Description

A kind of extensive angle, comprehensive can regulate arbitrarily sweep the wind-powered electricity generation fan automatically

Technical field:

Utilize aerodynamic principle to make the common electrical fan be transformed into comprehensive (360 °) adjustable wind-powered electricity generation fan of sweeping, in order to improve full chamber air, it belongs to the fluid mechanics application.

Background technique:

Electric fan comes out century more than one nearly, and kind development therebetween also is multifarious: horizontal displacement formula (100.About), vertical supending roll type (to improve the firing angle covering scope), 90 ° of dicyclo twin shafts movable (30 each other.About face upward bow) etc. all be utilize mechanical turbine, scroll bar and torque arm to drive to turn to change left and right, upper and lower jet flow sweep to and do limited part and wave and sweep wind and improve the firing angle covering scope, certainly also occur electronic control (program control type) in the recent period and make gentle breeze, natural wind and face upward the angle of bowing (about 30 °) up and down, sweep the wind purpose but always reach by mechanical transmission such as turbine, scroll bar, torque arm at last in any case, its deficiency shows that all rotating angle is limited.

Summary of the invention:

The present invention is the kind of drive of abandoning prior art, reduce mechanical transmission fault probability, it is to utilize similar existing a kind of on record moving runner (non-driven by motor) of angle of attack cover that is provided with, but we only do it: drying to allow it produce running torque and do not have other when fan becomes the wind purposes, this is enclosed within the runner of fan blade front, the wind energy that provides by fan blade by fluid mechanics principle can produce reaction " couple " and can promote this runner and do coaxial turn (but not being and the fan blade interlock that it is moving that its belongs to unregulated power body) when axial jet runs into when this runner is provided with many angle of attack blades.Key is that the outer of the rotating disk (1) in this wheel is located to add to do some protruding peach formula slopes (2) that have, fast speed is swept in its protruding peach number decision, this protruding peach slope peak energy is constantly touched resilient sphere feeler lever (3) when making it meet the wind rotation, produce the shunt running couple, and this feeler lever is to be fixed on the axial cross bar (4) with electric fan, it can center on the center---and with bearing (8) is that the suspension rod (7) of round dot is done 360 ° of turns at a slow speed, and it leads to two power lines of motor, tie up in the bearing box with two collector rings (5), with be contained in an insulator on contact power supply by two the flexible brushes (6) on its lid do interaction, power line is twisted off because of 360 ° of continuous turns with regard to avoiding like this.Electric fan is to be fixed on the cross bar (4), and it also can do 360.(by regulating card (9)) regulated in turn, and it is fixing between fan (11) and fixed card by Hooke's universal joint (10) (locking device is arranged), so just constitute three-dimensional can regulate, can finish the comprehensive wind purpose of sweeping, thereby the air-flow that improves the interior space effectively is even suitable, reaches to radically reform and heat radiation comprehensively.From performance electric fan technology has been very ripe, and not enough person sweeps the wind angle limited by mechanical drive mode in the aestheticism, and is less than normal! By designing this unique texture and varied wide-angle that combines with prior art and the kind that contains than long drive journey scope according to different market demands behind the such scheme, select and satisfy the reasonable product of various varying environment demands for different Consumers, singly hang in conjunction with (seeing accompanying drawing) as two commentaries on classics, in like manner also can do single the commentaries on classics and hang combination, vertical two commentaries on classics, desk-top single, double commentaries on classics etc.Also just reduce fault generation probability such as therefore causing wearing and tearing from the life-span owing to abandon turbine, scroll bar, torque arm mechanical transmission, relatively say and also can reduce part energy consumption (energy-conservation), this method great advantage is the investor so long as possess electric fan specialized factory, can retrofit soon (simple in structure), and the other parts of the world of end discovery still have the extensive angle that adopted this type of control to sweep the wind-powered electricity generation fan at present.

Description of drawings:

(1), (1 ') is can regulate two dimension electric fan, (2) be that the anterior impeller outer of electric fan is along the protruding peach formula slope rotating disk of locating, (3) be the flexible ball face feeler lever (movable adjustable) that contacts with protruding peach, (4) be cross bar, it and bearing outside fix on the tray both sides, and (5) are for being equipped with two collector rings that insulate with periphery in the tray, (6) be the tray lid, two brushes that insulate with periphery are housed, and (7) are hollow suspension rod (length is adjustable), (8) bearing.

Embodiment:

The electric fan (watt level visual surround space size and decide) of wheel rotating disk before having with two, it can make two-dimensional adjustment, be installed in the cross bar two ends, bearing (8) is housed in the middle of the cross bar, the design of two electric fan wheel rotating disks have protruding peach formula slope several, it and two are installed in terminal feeler lever (3) rubbing contact of cross bar (4), the feeler lever end is that elastic sphere can be with "---〉" F1, the F2 couple is passed to cross bar (4), after rotating, two fans send wind energy, the reaction force that produces can promote impeller and do coaxial rotation when its jet ran into the runner that is provided with angle of attack blade, at this moment its wheel disc periphery be provided with peak, protruding peach formula slope will periodically constantly touch have that elasticity is touched thick stick (3) and by it with couple F1, the F2 mode is given whippletree (4) work done, thereby promote cross bar and drive 360 ° of rotations continuously that two electric fans works are the center with the bearing, its jet is also just done 360 ° and is revolved and penetrate, hanging a common ceiling fan again as for vertical lower plays and cooperates jet to contain face, try to achieve the even genial no dead angle of air-flow, be unlikely to electric fan wind and blow, make the people feel nature and happy as A pleasant breeze blows gently facing to a direction.(5), (6) be electric current by with two collector rings and the brush of peripheral insulation board, it guarantees at 360 ° of unlikely electric wires that twist off of rotation continuously.

Claims (2)

1. extensive angle, comprehensive adjustable wind-powered electricity generation fan of sweeping automatically, it is to sweep the wind heat radiation with the driven by motor fan blade, not to be to regulate swing angle size different with regulating method with prior art common electrical sector for they, the described wind-powered electricity generation fan of sweeping automatically comprises: vertical suspension rod, cross bar, regulate card, prop up card, feeler lever, be contained in two electric fans on the cross bar two ends, and be sleeved on the blade rotary wheel that has the angle of attack on two electric fans on the cross bar two ends, it is characterized in that: feeler lever is to link to each other with cross bar (4) admittedly with adjustable way, utilize aerodynamic principle to become the couple that promotes this blade rotary wheel rotation with two electric fan jets that reaction couple form will be contained on the cross bar two ends with the blade rotary wheel that has the angle of attack, some protruding peach formulas slope also is set at the blade rotary wheel edge simultaneously, and remove to touch front end by this protruding peach formula slope and have sphere and have light and soft flexible feeler lever (3), thereby make the cross bar rotation, produce shunt running couple (F1 continuously by energy of rotation, F2), making the electric fan work of two automatic and adjustable joints that are contained in cross bar (4) two ends almost is that friction-free revolving at a slow speed penetrated for 360 ° around vertical suspension rod work, and the common electric fan of prior art is then with turbine, scroll bar, the torque arm machinery type is done to strafe back and forth in the limited angle.
