Embodiment
Fig. 1 is the structural representation according to the solar-energy light collector of one embodiment of the invention.As shown in Figure 1, solar-energy light collector comprises cylinder groove supporting surface 110, catoptron optically focused array 120, steel wire 130, mechanical drive control system 140, absorption plant 150 and the fixed support 160 of connection chip architecture.
Cylinder groove supporting surface 110 has recessed cylindrical shape or director circle cylindrical shape, is made up of some support frames (not shown) and some arc-shaped rails (not shown).Each arc-shaped rail is fixed on the fundamental plane, and its center of circle forms the cylinder groove axis all point-blank.The support frame layout that parallels to the axis, two ends are limited in the guide rail, form the cylinder groove supporting surface.The plane passing the cylinder groove axis and divide the cylinder groove supporting surface equally is called the cylinder groove shaft section.
The catoptron optically focused array 120 of connection chip architecture is configured in above the cylinder groove supporting surface 110.The catoptron optically focused array 120 of connection chip architecture is made of at least two ribbon catoptrons.The length direction of each ribbon catoptron is along the axis direction of cylinder groove supporting surface, and its Width is along the circumferencial direction of cylinder groove supporting surface.
Form by the mechanical hook-up flexibly jointed chain between the described ribbon catoptron.In an example, described flexibly jointed chain is realized by hinge or soft band.Described each ribbon catoptron is adjacent that catoptron is closely linked together and relative position is fixed, and entire emission mirror optically focused array can cover whole cylinder grooves.
Solar energy absorption plant 150 is installed in cylinder groove axis place.This solar energy absorption plant can be photo-thermal or photovoltaic absorption plant, also can be photo-thermal photovoltaic set composite or other helioplant.In an example, this absorption plant is tubulose or strip.Need explanation, absorption plant 150 also can be installed in cylinder groove near axis or other parallel with it position.
The shape of connection chip architecture catoptron optically focused array 120 is configured to and can will reflexes to cylinder groove axis place with parallel with the cylinder groove shaft section and the vertical sunshine that passes the direction incident of cylinder groove axis, promptly in the space that the absorption plant size limits.
The effect of steel wire 130 and mechanical drive control system 140 is myotatic reflex mirror optically focused array 120, and making it to be axle with the cylinder groove axis in arc-shaped rail, is that radius moves with arc-shaped rail place radius of a circle.Therefore, connection chip architecture catoptron optically focused array can be with the variation of the angle of incident sunshine keeps along the circumferencial direction unitary rotation of cylinder groove and in rotation process sunshine is reflexed to state in the space that the absorption plant size limits.
Mechanical drive control system 140 is by the real-time feedback to solar motion, and the rotation of control connection chip architecture catoptron optically focused array makes its real-time follow-up sun's motion.In tracing process, the rotation of connection chip architecture catoptron optically focused array is constantly carried out, and satisfies the continuity of following the tracks of.
160 pairs of guide rails of fixed support play a supportive role, make in tracing process catoptron optically focused array in groove when guide rail moves, arc-shaped rail maintains static.
Fig. 2 is a kind of synoptic diagram of sun optically focused principle.As shown in Figure 2, the circular arc 210 with certain radius is xsects of Fig. 1 cylinder groove supporting surface.Para-curve 220-1,220-2,220-3 are the xsects of a series of cylindrical curved surface, are the family of parabolas that main shaft is overlapping and focus is identical.In an example, the center of circle of focus and circular arc 210 is overlapping.
From the angle of three-dimensional, the line segment of reservation is that a series of xsects are the band of a para-curve part.These bands are end to end on the cylinder groove supporting surface.
By on the surface of band, plating reflectance coating, promptly formed the connection chip architecture catoptron optically focused array that previous embodiments is mentioned.
When sunshine directly over the cylinder groove supporting surface during vertical incidence, because incident light is parallel to each parabolical main shaft, parallel incident beam becomes convergent beam after the reflection of the connection chip architecture catoptron optically focused array on the cylinder groove supporting surface, converge on the focus separately.As mentioned before, different para-curves have identical focus.Therefore, parallel incident ray converges to same place, converges on the cylinder groove axis under the overlapping situation of focus and cylinder groove axis.
Fig. 3 is the synoptic diagram that utilizes the connection chip architecture catoptron optically focused array of principle formation shown in Figure 2.Be positioned at catoptron 320-1 and 320-8 on the cylinder groove supporting surface 310,320-2 and 320-7,320-3 and 320-6,320-4 and 320-5 correspond respectively to para-curve 220-1 shown in Figure 2,220-2, the part of 220-3 and 220-4.When the sunshine vertical incidence, the mirror 320-1 that is reflected respectively ... and the 320-8 reflection, point to the absorption plant 150 that is positioned at the common focus place.
Need explanation, it is a parabolical part that the cross-sectional profiles of each ribbon catoptron not only can be chosen as, and can also be the combination of various straight lines, curve or straight line and curve.Certainly, such shape of cross section should satisfy the condition in the space that will reflex to the qualification of absorption plant place or its size with the sunshine of the parallel incident of cylinder groove shaft section.
In an example, be continuous between each ribbon catoptron, do not block mutually.Figure 10 is the synoptic diagram of the embodiment that do not block mutually of a catoptron.Catoptron 1020-1, the linking part between the 1020-2...1020-8 is parallel with parallel incident light, therefore can not block mutually each other.
In an example, described ribbon catoptron is made by the minute surface of high reflectance or the minute surface of the alternative reflection of wavelength.
In an example, each ribbon catoptron width can both be radiated near the absorption plant reflected light that satisfies band, promptly in the spatial dimension of its size restrictions by the size decision of absorption plant.For reaching high light gathering efficiency, strip width further can be dwindled, satisfy the sunray that is radiated on it and substantially all reflex in the described scope.The concrete size of absorption plant is looked factors such as method for making, material, focusing ratio, bearing accuracy and is determined.
In addition, as seen from Figure 2,, can select to join the quantity of the ribbon catoptron of chip architecture catoptron optically focused array by selecting parabolical quantity; Select each parabolical summit spacing size, can adjust the width of the ribbon catoptron of connection chip architecture catoptron optically focused array.
Because the rotation of the earth, the position of the relative catoptron optically focused of sun array is all changing at any time.If each catoptron still is in the origin-location, the overwhelming majority that is radiated the sunray in the catoptron optically focused array can't be reflexed to the absorption plant at described axis place, promptly cause a large amount of energy dissipations, thereby capacity usage ratio reduces greatly.The present invention drags connection chip architecture catoptron optically focused array by the mechanical drive control system and moves in arc-shaped rail, realizes the tracking of catoptron optically focused array to solar azimuth, thereby can assemble sunshine well in the real-time follow-up solar motion.
Optically focused principle schematic when Fig. 4 is the sunray oblique incidence.As shown in Figure 4, when the sunray oblique incidence, catoptron optically focused array moves with the flexibility interlock form of multi-disc combination in arc-shaped rail under the control of mechanical drive control system, make the relative cylinder groove shaft section of shaft section (calling system's shaft section in the following text) of catoptron optically focused array tilt, and parallel with the sunshine incident direction.So, sunshine incides the catoptron 420-1 that is positioned on the cylinder groove supporting surface 410 with the direction that is parallel to system's shaft section, 420-2 ..., and 420-8.Catoptron 420-1,420-2 ... and 420-8 reflexes to incident ray common focus respectively, thus with solar light focusing to the heat sink 150 that is installed in the focus place.
By setting to the mechanical drive control system, can control the movement velocity and the direction of catoptron optically focused array, make described system shaft section always be parallel to the direct sunlight line, thereby make the sunray that shines in the catoptron optically focused array all be reflected to the absorption plant at described axis place.
Fig. 5 is the synoptic diagram that drags catoptron optically focused array.As shown in Figure 5, (comprise ribbon catoptron 320-1,320-2 when catoptron optically focused array 320, ..., when and 320-8) needs were mobile, mechanical drive control system 140 was by steel wire 130, and traction array 320 moves with speed V along arc-shaped rail in cylinder groove supporting surface 110.In Fig. 5, catoptron 320-1 ... and 320-8 moves to left, and wherein catoptron 320-3 has moved to the bottom of cylinder groove supporting surface, and mirror reflects mirror 320-8 has moved to outside the cylinder groove supporting surface.Therefore, connection chip architecture catoptron optically focused array can be with the variation of the angle of incident sunshine keeps along the circumferencial direction unitary rotation of cylinder groove and in rotation process sunshine is reflexed to state in the space that the absorption plant size limits.
Fig. 6 is the structural representation of catoptron optically focused array.As shown in Figure 6, the first web member 610-1 and the second web member 610-2 are arranged at the two ends of catoptron 610, the first web member 620-1 and the second web member 620-2 are arranged at the two ends of catoptron 620.The second web member 610-2 and the first web member 620-1 are combined together, and form a flexibly jointed chain.
Figure 11 is the schematic cross-section of flexibly jointed chain between the catoptron.Back-shaped 1110-1 is processed on one side of catoptron 1110, and another side is processed into hook 1110-2.Equally, one side catoptron 1120 be processed into back-shaped 1120-1, another side is processed into hook 1120-2.When two catoptrons connect, the termination of back-shaped 1120-1 of catoptron 1120 was slipped in the hook 1110-2 of catoptron 1110, forms loose fit with it, makes can relatively rotate between catoptron 1110 and 1120.
Get back to Fig. 6, non mirror part can be opened hole 630 near the flexibly jointed chain, so that ventilate, thereby reduces the resistance of wind.
It is noted that flexibly jointed chain can form between the catoptron or between the arrangement of mirrors.
In a specific embodiments, solar-energy light collector of the present invention is fixed on the ground by south-north direction, in the river shoal or desert such as spaciousness.When the sun moves westerly from east, the mechanical drive control system is by the tracking to solar azimuth, the flexibility interlock form motion that control catoptron optically focused array makes up with multi-disc toward east from the west in arc-shaped rail, guaranteeing can both to make at any time sunshine being parallel to the direction incident of system's shaft section, thus with solar light focusing to heat sink.In an example, in connection chip architecture catoptron optically focused array rotating process, it can be curling or crooked that this array turns to the outer part of track.When the relative position between the reflecting surface is in orbit fixed.
Fig. 7 and Fig. 8 are respectively the variation synoptic diagram of sun solar-energy light collector when diverse location.
The solar-energy light collector course of work is as follows: suppose the morning sun also in the east the time, catoptron optically focused array 320 towards with the position as shown in Figure 7.In Fig. 7, catoptron 320-6,320-7 and 320-8 move to the right side of cylinder groove supporting surface, and catoptron 320-1 ... and 320-5 then is hanging to beyond the supporting surface.When sunshine incides catoptron 320-6, when 320-7 and 320-8 are last, pass through reflection, light is focused on the absorption plant 150, and absorption plant 150 will absorb all luminous energy from catoptron.When the sun moves westerly, suppose to move to as shown in Figure 8.In Fig. 8, catoptron 320-1,320-2 and 320-3 move to the left side of cylinder groove supporting surface, and catoptron 820-4 ... and 720-8 then is hanging to beyond the supporting surface.At this moment, sunshine incides catoptron 320-1, and on 320-2 and the 320-3, through reflection, light is focused on the absorption plant 150.
It is axle that catoptron optically focused array is dragged in arc-shaped rail with the cylinder groove axis by steel wire under the control of mechanical drive control system, xsect place radius of a circle with arc-shaped rail is that radius moves, solar azimuth is followed the tracks of, what it moved to makes the sun incide light and the parallel condition of system's shaft section in the beam condensing unit towards satisfying with the position, it is identical with the angle of solar azimuth variation promptly to make catoptron optically focused array rotate, keep and sun synchronization, thereby make solar-energy light collector always obtain the highest light gathering efficiency, produce high optically focused ratio.
In the process of above-mentioned motion control, catoptron optically focused array moves in arc-shaped rail and realizes tracking to solar azimuth, and arc-shaped rail then is fixed on the ground motionless.Therefore, the present invention is firm in structure, and wind resistance is good, is fit to be applied in the helioplant under the most weather conditions of China.
Because catoptron optically focused array moves in arc guide rail with the flexibility interlock form of multi-disc combination when following the tracks of solar motion, follows the tracks of need not to rotate huge back-up system.
And because the catoptron optically focused array that is installed in the arc-shaped rail can be with the glass capsulation of high permeability, extraneous natural wind can not act directly on and be used for light harvesting mirror surface array, that is mirror array can not be subjected to the effect of extraneous wind-force.Therefore, this mirror array can be used very thin very light material, can use paper material under the extreme case, plates reflectance coating on the surface of paper material and gets final product, and the mechanical motion control system is simple, and the power that motion needs is little, has reduced the cost of device.
Need explanation, solar-energy light collector of the present invention can also be used to realize the bunching action of other radiation.
In addition, solar-energy light collector also can be used for the reverse transfer to radiation.
