Ship Anti-rolling Device for Wave Electricity Generation and Wave
Power System
Technical Field
This invention relates to the field of marine technology and power generation, particularly to a ship anti-rolling device for wave electricity generation and wave power system.
Background
Since American ship Columbia installed first electric lamp in 1880, the marine power capacity has also been expanding along with the increases of tonnage, speed, and performance of the ships. One of the characteristics of today's technology development is reflected in the use of electric propulsion of a ship, which a specific power generator is used for the electric motor to drive the propeller for ship propulsion, while other marine generators are used to supply electricity for service load. One of the main trend of the future development of marine technology will be reflected in applying the electrical equipment on board to replace many of non-electrical devices (such as the steam-driven heaters, washing machines, kitchen equipment, etc.; the hydraulically driven steering systems, dive systems, etc.; pneumatically driven valves, brakes, scuba diving system, the ship turbine start, etc.) to make an all-electric ship (United States, Mukuund R. Patel: Shipboard Electrical Power Systems, 2012).
Therefore, the demand for ship power capacity is still increasing further. It is well known, that electrical power is easy to use, but not so to store in large quantity. A ship generator is similar to a public power plant, where almost all of the power can be used in time. Ship power capacity demand, is big, as well as the power generation of ship generators, and so the energy consumption (a ship generator mainly consumes diesel) is large. When it is in port, a ship can be connected to a power supply on shore to turn off the auxiliary engines of diesel generator sets that contaminate harbor; when sailing in the ocean, a lot of energy consumption is difficult to avoid. Taking into account the natural and inexhaustible wave energy around a ship, the present invention is to investigate a device for electricity generation based on the use of wave energy to supply electricity for ships sailing in the ocean.
The wave is one of the moving form of the sea, resulting from the interaction of external forces (such as wind, changes in atmospheric pressure, celestial tidal forces, etc.), l gravity and surface tension of the sea water. When the waves form, the water points move in the shock and displacement, and changes in their position produce the corresponding kinetic and potential energies. The wave energy is the sum of kinetic and potential energies of waves on the sea surface, proportional to the square of wave height, period of wave motion and the width towards the wave front. It can be estimated by the changes in the water potential of the ups and downs, i.e., P = 0.5TH2 (P stands for the wave power per unit width of wave front, in kw/m; T the wave period, in s; H is the wave height, in m). It has been estimated that the wave power of world's oceans can reach 70 billion kilowatts; in the areas with a high density of wave energy flow, the wave energy flow per one meter off the coast is sufficient to provide illumination for 20 families. Wave power is the main form of wave energy utilization.
The electricity generation of wave power in practice always used pneumatic devices of wave power in the early stage. Large-scale research and development of wave power began in 1970s. The oil crisis made people pay more attention to the value of wave energy. United Kingdom, Japan, United States, Norway, France, Spain and China among others have made significant achievements in the field of wave power research and development. Among them, the relatively more mature devices of wave power are basically three types.
1, Oscillating water column type; it uses a container device in a fixed volume, communicating the sea, where the position change of water surface generated by waves causes the volume change of air in the container and compresses the air (intermediate medium) to drive the impeller of the power device for electricity generation. The wave power station of 100KW (fixed shore style) at Shanwei, Guangdong Province, China (built by Guangzhou Institute of Energy, Chinese Academy of Science), Japanese power boat "Hamming" (floating type) and other wave power devices for beacon lights are all of this type. For example, Japanese power boat "Hamming", by Japan Marine Science and Technology Center built in 1978-1979, is a floating equipment of 80 meters long and 12 meters wide, consisting of 22 air piston chambers with openings underneath, wherein the air is compressed and expanded with the ups and downs of wave movements, forming a high-speed air flow through the nozzle to collide the turbine to rotate for electricity generation, and achieving in small scale the electricity transmission to land, which Japan has taken as the most preferred option of "Island Power". Japanese power boat "Hamming" is not in true sense of a boat, not to supply electricity for ship, but essentially a prop-type wave power station floating offshore of the oscillating water column type.
2, Mechanical type: it uses the wave movement to drive the active parts of the device - "Nodding Duck", raft, float, roller, "Mejillon", "Sea Snake", "Anaconda", "Sea Carpet" among others, where the moving parts compress oil, water or other intermediate media to drive the power devices for electricity generation. For example, "Nodding duck" type device was invented by Saltin UK (1973). The device uses a duck-shaped cam, which gets the "Duck" rise its head when the wave hits "Duck", because the surface water has a big impact on "Duck", while the deep water has a small impact. After its wave-peak passed, the wave impact weakens to make "Duck" bow. "Nodding duck" swings up and down around the central axis to drive working pump, converting the kinetic and potential energies of waves to mechanical energy to drive the generator for electricity generation.
3, Water flow type: it uses a shrink waterway to introduce the waves into a high-level reservoir, forming water level difference, i.e. water head to be used for directly driving the turbine generators for electricity generation. For example, Norway built two wave power stations near Bergenin 1985. One was a power station with a convergence groove collecting waves, built based on the above principle. The device for collecting waves is used to gather the waves in a range of 10 kilometers to a narrow entrance in width of 500 meters, when the waves rise up to 20 meters in height and enter a large funnel groove to be pressed into a 100-meter high reservoir, where the water level difference is used to generate electricity.
So far wave power is limited to the areas near the coastline constructing shore-based hydraulic structures or offshore floating bodies (fixed to the sea bed by mooring or anchoring with the solving the undersea electricity transmission problems) for collection of the waves and installation of electricity generation equipment there. It is also contemplated that the electricity generation may be combined with the wave absorption to improve coastal environment and develop the device for wave absorption and electricity generation, which can generate electricity, but also smooth the coastal sea to benefit both aquaculture and ships berthing at port.
However, the wave energy in oceans is little to make use in practice, and obviously, a ship in the ocean need to have some kind of structure receiving the wave-impact to absorb wave energy and convert it into useful mechanical energy for the designing a suitable ship device for wave power generation using this mechanical energy to generate electricity. Anti-rolling device of the ship is directly related to the action of wave force, such as bilge keel, fin stabilizer, anti-rolling rudder ... and so on. But these traditional anti-rolling device or system is fixed to the hull, relatively stationary; or consuming the active movement of shipboard energy to do work against the wave force. These means of anti-rolling determine their unsuitability as the above-mentioned structure on the hull capable of absorbing wave energy to use its mechanical energy for electricity generation.
Nevertheless, the present inventor has a recently authorized patent "A Ship Anti-rolling Device" (patent number: ZL 2013 2 0278249.X), involving a structure arranged on both sides of the hull, termed as sidewalls, which can make mechanical movement in inward and outward cycle upon the periodic action of wave forces in the ocean. In short, its upper end is fixed to the elastic parts as coil springs, while its inside is attached to the airbags equivalent to the sealed containers containing a quantity of gas in compliance with Boyle - Mariotte specific law. The sidewall turns inward under the wave force to press the elastic parts and airbags, the mechanical energy converted from wave energy is further transmitted into the elastic potential energy and gas pressure potential energy; when the action of waves retreats periodically, it turns outward upon the above elasticity and gas pressure. Its effect is anti-rolling.
In view of the above problems and shortcomings, a ship anti-rolling device for wave electricity generation comes on the agenda that makes the ship in the ocean use the waves to generate electricity and have a capacity of anti-rolling at mean time. Summary of the Invention

Embodiment 1
As shown in Fig. 1, a ship anti-rolling device for wave electricity generation provided by this embodiment includes a marine wave power generation mechanism and a shipside wave force absorption mechanism providing motive power for the former mechanism, wherein the shipside wave force absorption mechanism consists of energy conversion moving walls 3 movably connected with the bilge of the ship, and the energy conversion moving walls 3 may produce mechanical movement under the action of the wave force; and the marine wave power generation mechanism generates electric energy under the drive of the energy conversion moving walls 3, for supplying power to the ship.
When the ship sails on the sea, the horizontal amplitude of rolling in shaking of six degrees of freedom, caused by the wave force, of a hull 13 is the largest, and wave energy driving the huge ship to roll horizontally may be converted into electric energy by the ship anti-rolling device for wave electricity generation, so that power supply to the ship and rolling reduction of the ship are realized.
As shown in Fig. 2, the marine wave power generation mechanism includes moving magnetic bar power generation equipment 1, wherein the moving magnetic bar power generation equipment 1 includes a magnetic bar 4, a solenoid 5 and a force application arm 6; one end (the outer end shown in the figure) of the magnetic bar 4 is fixed on the top of the energy conversion moving wall 3 through the force application arm 6, the other end (the inner end shown in the figure) of the magnetic bar 4 faces the outer opening of the solenoid 5, and the magnetic bar 4 penetrates through the solenoid 5 to and fro under the drive of the energy conversion moving wall 3; and the force application arm 6 is positioned on the top of the energy conversion moving wall 3 and fixedly connected with the energy conversion moving wall 3 into a whole.
The specific movement state of the magnetic bar 4 is as shown in Fig. 3 and Fig. 4, namely the magnetic bar 4 may get into the solenoid 5 along the penetrating direction 14 and then get out of the solenoid 5 along the exiting direction 15. Further, the magnetic bar 4 is a bar magnet or an electromagnet; and the solenoid 5 consists of metal conductor windings.
The energy conversion moving walls 3 are board walls on the shipside, which may move under the action of the wave force and are positioned on two sides of the ship, the lower end of the energy conversion moving wall 3 is movably connected with the bilge of the ship through a rotating shaft 18, a frame 24 is arranged outside the energy conversion moving walls 3, and the energy conversion moving walls 3 stretch from the bilge of the ship toward the outer upper direction externally leaning against the frame 24; and wave may impact the energy conversion moving walls 3 through the frame 24. As shown in Fig. 9-12, an elastic component 17 is fixedly connected between the energy conversion moving wall 3 and the hull 13.
The elastic component 17 may be wound on the magnetic bar 4 and used for producing elastic deformation along the axial direction of the magnetic bar 4. An appropriate clearance is reserved between the elastic component 17 and the magnetic bar 4, so that the magnetic bar 4 may move relatively in the elastic component 17 and also has a similar effect of a guiding rod for the elastic component 17, and the stability of retraction and extension of the elastic component 17 is facilitated.
The inner end of the elastic component 17 is fixed at the outer opening of the solenoid 5 on the hull 13, to ensure that the hollow part in the elastic component 17 is communicated with the cavity of the solenoid 5.
Correspondingly, the solenoid 5 is positioned in the hull 13 and connected with the elastic component 17 through a guiding support 19. The guiding support 19 is used for guiding the magnetic bar 4 to penetrate through the solenoid 5 to and fro, to ensure that the magnetic bar 4 may smoothly get into and get out of the outer opening of the solenoid 5.
Preferably, the guiding support 19 is positioned at the joint of the inner end of the elastic component 17 and the outer opening of the solenoid 5, and the guiding support 19 is coated with a lubricant or provided with balls to reduce the friction when the magnetic bar 4 gets in and gets out of the solenoid 5. Moreover, a guide sleeve 20 is sleeved outside the elastic component 17, the guide sleeve 20 is arranged along the movement locus of the force application arm 6 when the energy conversion moving wall 3 rotates around the rotating shaft 18, and the limiting effect of the guide sleeve 20 is favorable for avoiding lateral bending after the elastic component 17 is loaded to keep the stability of retraction and extension of the elastic component 17.
Moreover, a guide sleeve gap 21 for accommodating the force application arm 6 is formed at the lower part of the guide sleeve 20 along the axial direction of the magnetic bar 4. The width of the guide sleeve gap 21 is smaller than the outside diameter of the elastic component 17 but larger than the width of the force application arm 6, the force application arm 6 may reciprocate along the guide sleeve gap 21, and the magnetic bar 4 connected with the force application arm 6 and the elastic component 17 correspondingly move along with the force application arm 6. Preferably, the guide sleeve 20 is fixed below a deck 25 thereon, and the deck 25 as well as a rain baffle 26 and a wave curtain 27 on the energy conversion moving wall 3 effectively protect the marine wave power generation mechanism between the hull 13 and the energy conversion moving wall 3 and the like from being corroded by seawater. It is worth noting that, the elastic component 17 includes any device with elastic deformation, wherein the elastic component 17 is preferably a cylindrical spiral compression spring.
Taking the elastic component 17 which is the cylindrical spiral compression spring as an example, the working principle of the moving magnetic bar power generation equipment 1 is as follows:
As shown in Fig. 7, when wave 32 surges to one side of the ship, the energy conversion moving wall 3 on this side rotates inwards, under the action of the wave force, by taking the rotating shaft 18 at the bilge as an axis, the force application arm 6 drives the magnetic bar 4 to rotate inwards and get into the solenoid 5, and the cylindrical spiral compression spring is compressed at the same time ;
as shown in Fig. 8, after the action of the periodic wave force on the energy conversion moving wall 3 disappears, the compressed cylindrical spiral compression spring stretches to drive the force application arm 6 to move outwards, so as to drive the magnetic bar 4 to rotate outwards and get out of the solenoid 5; and meanwhile, the energy conversion moving wall 3 leans against the frame 24 agai ;
the process is repeated, when the magnetic bar 4 gets into and gets out of the solenoid 5, the induced electromotive force produced by the variation of magnetic flux in the solenoid 5 is guided to a circuit through a terminal to produce current, and the electric energy is output by a circuit unit (rectification, current conversion, frequency conversion or voltage conversion) to supply power to the ship.

The present invention further provides a wave power system, including the ship anti- rolling device for wave electricity generation in the above embodiments.

In conclusion, when the components on the hull are designed as the shipside wave force absorption mechanism for receiving wave energy and generating mechanical energy for power generation in the present invention, reference is made to the side walls involved in the preceding patent "Anti-Rolling Device for Ship" (Patent No. ZL201320278249.X) of the inventor, which are refitted into the energy conversion moving walls 3 which are obviously different on the aspects of comprehensive structure, beneficial effects and the like and are matched with the marine wave power generation mechanism, wherein the main improvement includes: (1) the force application arm 6 at the upper end of the energy conversion moving wall 3 is fixedly connected with one end of the magnetic bar 4 of the moving magnetic bar power generation equipment 1, and drives the magnetic bar 4 to get into and get out of the solenoid 5, so that power is generated as a main effect; and (2) the inner side of the energy conversion moving wall 3 is attached to the outer wall of the bellows 10 of the bellows air duct power generation equipment 2, the controllable valve 23 is arranged on the upper wall 22 of the bellows 10, the air duct 7 is formed in the device, the airflow in the air duct 7 may drive the impeller 8 and the generator 9 rotor, and the energy conversion moving walls 3 move mechanically to extrude the bellows 10 so as to achieve the beneficial effect of power generation.
As for more comprehensive key analysis, the main technical problem to be solved by the present invention, the adopted main technical means and the achieved main beneficial effect are significantly developed and differ from those of the preceding patent "Anti-Rolling Device for Ship" (Patent No. ZL201320278249.X) of the inventor, and the difference mainly lies in marine wave power generation: the preceding patent "Anti-Rolling Device for Ship" (Patent No. ZL201320278249.X) of the inventor is completely irrelevant with power generation on any aspect; while the main technical problem to be solved by the present invention is to generate power with wave energy when the ship sails on the sea, the main technical means adopted by the present invention is to provide the marine wave power generation mechanism (including the moving magnetic bar power generation equipment 1 and/or the bellows air duct power generation equipment 2) and the shipside wave force absorption mechanism providing motive power for the marine wave power generation mechanism, and the achieved main beneficial effect is to convert the wave energy into electric energy and supply power generated by wave to the ship.
In the present invention, in order that the energy conversion moving walls 3 timely rotate outwards to reset after the periodic wave force disappears and no additional energy is consumed for this, when the energy conversion moving walls 3 rotate inwards under the action of the wave force, the wave energy is converted into electric energy by the ship anti-rolling device for wave electricity generation, and a part of the wave energy is converted into elastic potential energy temporarily stored in the deformed elastic components 17 which are cylindrical spiral compression springs in this embodiment at the same time; with respect to the proportion of the electric energy and the elastic potential energy converted from the wave energy, the design strength and rigidity of the cylindrical spiral compression springs may be set low within an available range, as long as the elastic potential energy of the loaded cylindrical spiral compression springs reaches a threshold, namely the cylindrical spiral compression springs may push the energy conversion moving walls 3 to rotate outwards and reset at the moment when the action of the periodic wave force disappears, and the wave energy does not need to be converted into elastic potential energy in an over-high proportion in the design of the ship anti-rolling device for wave electricity generation.
In the moving magnetic bar power generation equipment 1, according to the Faraday's law that an induced electromotive force is produced by the variation of magnetic flux in a closed circuit, the induced electromotive force produced when the magnetic bar 4 gets into and out of the solenoid 5 is guided to the circuit through a terminal to produce current, and the power generation quantity is related with the quantity of metal conductor windings of the solenoid 5 and the physical parameters of the magnetic bar 4, such as magnitude of exciting current of the electromagnet and the like. Meanwhile, according to the Lenz's law that the effect of the induced current is such that it always opposes the cause which produces it, the magnetic bar 4 is subjected to certain repulsion when getting into and out of the solenoid 5, while the magnitude of the repulsion may be adjusted according to the sea condition and the rotating condition of the energy conversion moving wall 3 as required, e.g. the magnitude of exciting current of the magnetic bar 4 is adjusted, thus facilitating (not hindering) periodic normal repeated mechanical movement of the energy conversion moving wall 3 along with wave and continuously maintaining the functions of power generation and ship-rolling reduction of the ship anti-rolling device for wave electricity generation; so that when the energy conversion moving wall 3 rotates inwards under the action of the wave force, namely the magnetic bar 4 gets into the solenoid 5, the magnitude of the repulsion borne by the magnetic bar 4 and the compressing forces on the elastic component 17 can be appropriate superimposed and transferred to the energy conversion moving wall 3 through the force application arm 6, and as a result, the energy conversion moving wall 3 continues to rotate inwards, namely the magnetic bar 4 continuously gets into the solenoid 5 (to generate power), and the wave force is effectively buffered (ship-rolling is reduced).
The mechanism of the bellows air duct power generation equipment 2 is as follows: when the energy conversion moving wall 3 rotates inwards under the action of the wave force to extrude the bellows 10 on the same side, because the controllable valve 23 of the bellows 10 on this side has been timely closed and the controllable valve 23 of the opposite bellows 10 is being timely opened, compressed air in the bellows 10 on this side quickly flows to the opposite bellows 10 (is discharged from the opened controllable valve 23 thereof) through the air duct 7, to drive the impeller 8 in the air duct 7 to rotate, so as to drive the generator 9 to generate power; the elastic potential energy of the loaded elastic component 17 after the periodic wave force disappears is released to drive the energy conversion moving wall 3 on this side to rotate outwards, the pressure in the bellows 10 on this side is negative, and air quickly flows to the bellows 10 on this side under atmospheric pressure through the opposite vent 28, the opened opposite controllable valve 23 and the opposite bellow 10 by virtue of the air duct 7, to drive the impeller 8 in the air duct 7 to rotate, so as to drive the generator 9 to generate power; and the atmospheric pressure is quickly transferred from the opposite side to the bellows 10 on this side, so that the energy conversion moving wall 3 attached to the outer wall of the bellow 10 on this side rotates outwards, the magnetic bar 4 gets out of the solenoid 5 and the moving magnetic bar power generation equipment 1 may generate power.
As well known, the wave power generation devices in the world respectively have advantages and disadvantages, but face some problems together: too many intermediate links while low efficiency and seawater corrosion when wave energy is converted into electric energy. However the moving magnetic bar power generation equipment 1 and the bellows air duct power generation equipment 2 of the present invention are simple in structure, the energy conversion moving walls 3 may directly push the magnetic bars 4 under the action of the wave force to penetrate through the solenoids 5, or extrude the bellows 10 to produce airflow for driving the impeller 8 to rotate so as to generate power, so there are not so many intermediate links; and the energy conversion moving walls 3 and the hull are shaded by the deck 25, the rain baffles 26 and the wave curtains 27, so that main equipment may be protected from being corroded by seawater.
The embodiments of the present invention are given for illustration and description, but are not meant to be exhaustive or limit the present invention to the disclosed form. Many modifications and alterations are obvious to those of ordinary skill in the art. The embodiments are selected and described for better describing the principle and practical application of the present invention and enabling those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications adapted to specific purposes.
