Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
To shown in Figure 2, a kind of wind-driven generator energy storage device, this energy storage device comprise frame 1, energy storage device 2, energy conversion device 3 and induction controller like Fig. 1.The roller bearing 22 that said energy storage device 2 comprises motor 21, be connected with motor 21, an end connect the strand cable 23 of roller bearing 22, connect the counterweight 24 of strand cable 23 the other ends; Output gear 31, axle center and output gear 31 axle center that the annular of the gear teeth all arranged inside and outside said energy conversion device 3 comprises at the input gear 32 on the same shaft axis, be located between input gear 32 and the output gear 31 and the inboard gear teeth of the gear teeth and output gear 31 and import the corresponding conversion gear 33 of the gear teeth of gear 32.Conversion gear 33 is connected an end of roller bearing 22 through coupling shaft 34, and conversion gear 33 can be around coupling shaft 34 rotations; Conversion gear 33 is more than or equal to 2 in the energy conversion device 3, and conversion gear 33 evenly distributes around input gear 32 axle center.
Working principle: the generator 21 of wind-driven generator that wind-driven generator 21 devices comprise windmill, connect the speed reducer A of windmill, input gear 32 connects speed reducer A 21 energy storage devices 2, the speed reducer B that is connected with wind-driven generator 21 energy storage devices 2 output gears 31, connection speed reducer B and be connected the induction controller that wind-driven generator 21 installs.Before generating, set induction controller, confirm the scope of wind-power electricity generation.
Wind-force just often; Generated energy is within the scope of wind-power electricity generation; If wind-force drives that windmill rotates and turn clockwise through the speed reducer A input gear 32 that drives wind-driven generator 21 energy storage devices 2 that slows down, input gear 32 drives conversion gears 33 and is rotated counterclockwise, and conversion gear 33 drives output gears 31 and is rotated counterclockwise; Output gear 31 drives speed reducer B, and speed reducer B drives generator 21 generatings.
When wind-force is big; Generator 21 generated energy are greater than setting range, and induction controller is connected motor 21 with unnecessary electric current, and motor 21 drives roller bearing 22 and turns clockwise; Roller bearing 22 rotations make strand cable 23 be wrapped on the roller bearing 22 and the counterweight 24 of slinging, and electric energy more than needed is converted into gravitational potential energy.If the wind-force endurance is longer, counterweight 24 is raised to the highest, after the induction controller induction; The fan blade angle conversion of control windmill stops operating windmill and is static, and input gear 32 is static, and counterweight 24 receives gravity effect to the whereabouts; Counterweight 24 drives roller bearing 22 and turns clockwise; Because of 32 slack roller bearing 22 rotations of input gear drive conversion gear 33 counterclockwise autobiographies, conversion gear 33 drives output gear 31 and is rotated counterclockwise generator 21 normal power generation.Respond to through induction controller when counterweight 24 drops to certain position (being minimum and the highest intermediate portion approximately), induction controller control roller bearing 22 stops operating, and the fan blade angle of control windmill is that windmill is rotated further the drive generating.If wind-force is less,, exhaust up to gravitational potential energy through induction controller control energy storage device 2 exoergic stable electric generations.
Because the adjusting of wind-driven generator 21 energy storage devices 2 makes the windmill generating more stablize the working efficiency that can also improve wind-driven generator 21
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
