DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0018] Embodiment one, please refer to Figures 1-6 A wind power generation device of a multi-fan-blade fan head, comprising: The wind power warehouse 200 is internally provided with a generator set for wind power generation, and the bottom of the wind power warehouse 200 is provided with a base 100 for support; The multiple groups of blades 300 have an inclination angle and are arranged at the side of the wind power warehouse 200; The output end of the multiple groups of blades 300 is provided with a hydraulic warehouse one 401 through bolts, the side of the wind power warehouse 200 is provided with a buffer warehouse 409, and the hydraulic warehouse one 401 and the buffer warehouse 409 are connected through a transmission member, the transmission member includes a hydraulic warehouse two 402 arranged at the side of the wind power warehouse 200, the inner wall of the hydraulic warehouse one 401 is slidably connected with a sliding block 404 through an arc elastic expansion rod 403, and the side of the hydraulic warehouse one 401 is slidably connected with an extrusion arc rod 405. When the wind is strong, the multiple groups of blades 300 rotate rapidly, driving the hydraulic warehouse one 401 bolted at the output end of the multiple groups of blades 300 to rotate rapidly, so that the sliding block 404 in the hydraulic warehouse one 401 is stretched under the action of centrifugal force, and the arc elastic expansion rod 403 is slid in the hydraulic warehouse one 401, so that the pressure in the hydraulic warehouse one 401 increases, driving the extrusion arc rod 405 slidably connected with the hydraulic warehouse one 401 to move.

[0019] One end of the hydraulic chamber two 402 is slidingly connected with a force rod one 406, the force rod one 406 is located at the side of the extrusion arc rod 405, and is in contact with the extrusion arc rod 405, the other end of the hydraulic chamber two 402 is slidingly connected with a top rod 407, the side of the force rod one 406 is equipped with a spring two 408, the end of the spring two 408 away from the force rod one 406 is equipped on the inner wall of the hydraulic chamber two 402. When the extrusion arc rod 405 is in a rotating state and synchronously extends, the extrusion arc rod 405 can extrude the force rod one 406 and drive the force rod one 406 to move to the side, cooperate with the hydraulic chamber two 402 slidingly connected with the force rod one 406, so that the pressure in the hydraulic chamber two 402 increases, and drive the top rod 407 slidingly connected with the hydraulic chamber two 402 to move upwards.

[0020] The top rod 407 is fixed at the bottom of the buffer chamber 409, the inside of the buffer chamber 409 is connected with a buffer rod 411 through the spring one 410, the top of the buffer rod 411 is fixedly connected with a buffer plate 412, and the inside of the buffer chamber 409 is equipped with a rubber block 413. When the top rod 407 moves upwards, the top rod 407 drives the buffer chamber 409 fixedly connected therewith to move upwards, the buffer chamber 409 drives the buffer plate 412 to move to the bottom of the output shaft of the plurality of blades 300 and contact with the output shaft, when the plurality of blades 300 shakes due to too high rotating speed, the buffer plate 412 can be extruded downwards, the buffer plate 412 drives the buffer rod 411 fixedly connected therewith to extrude the spring one 410 and move downwards, and the buffer rod 411 moves to the rubber block 413 in sequence and rubs the rubber block 413 violently to buffer, after the buffering operation is completed, the buffer rod 411 and the buffer plate 412 can be reset under the action of the spring one 410. In this way, corresponding buffering operation can be performed in this case to reduce the possibility of damage.

[0021] When the wind force is weakened, the sliding block 404 loses the centrifugal force effect and can be reset under the action of the arc-shaped elastic telescopic rod 403, and the extrusion arc rod 405 is reset, the force rod one 406 loses the limitation of the extrusion arc rod 405 and can be served under the action of the spring two 408, so that the device is reset. In this way, when the floating is small, the use of the buffer chamber 409 is stopped, and the spring one 410 in the buffer chamber 409 is prevented from being damaged due to long-term use, so that the use time of the buffer chamber 409 is prolonged.

[0022] The top of the wind power generation chamber 200 is equipped with a hot air assembly 500 for preventing the plurality of blades 300 from icing, and the top of the wind power generation chamber 200 is equipped with a cleaning assembly 600 for cleaning the wind power generation chamber 200.

[0023] When in use, when the wind is strong, the plurality of blades 300 rotate rapidly, driving the hydraulic chamber one 401 assembled on the output end of the plurality of blades 300 to rotate rapidly, so that the sliding block 404 in the hydraulic chamber one 401 is stretched under the action of centrifugal force, stretching the arc-shaped elastic expansion rod 403 and sliding in the hydraulic chamber one 401, so that the pressure in the hydraulic chamber one 401 increases, driving the extrusion arc rod 405 connected with the hydraulic chamber one 401 to move. At this time, the extrusion arc rod 405 is in a rotating state and is simultaneously extended, so that the extrusion arc rod 405 can extrude the stress rod one 406 and drive the stress rod one 406 to move to the side, cooperating with the hydraulic chamber two 402 connected with the stress rod one 406 to make the pressure in the hydraulic chamber two 402 increase, driving the jack 407 connected with the hydraulic chamber two 402 to move upward, so that the jack 407 drives the buffer chamber 409 fixedly connected thereto to move upward, and the buffer plate 412 is driven by the buffer chamber 409 to move to the bottom position of the output shaft of the plurality of blades 300 and contact with the output shaft. When the plurality of blades 300 shake due to excessive speed, the buffer plate 412 can be extruded downward, so that the buffer rod 411 fixedly connected with the buffer plate 412 extrudes the spring one 410 and moves downward. The buffer rod 411 is then sequentially moved to the rubber block 413 and rubbed with the rubber block 413, thereby buffering. After the buffering operation is completed, the buffer rod 411 and the buffer plate 412 can be reset under the action of the spring one 410. When the wind weakens, the sliding block 404 loses the action of centrifugal force and can be reset under the action of the arc-shaped elastic expansion rod 403. Similarly, the extrusion arc rod 405 is reset, and the stress rod one 406 loses the restriction of the extrusion arc rod 405 and can be reset under the action of the spring two 408, so that the device is reset.

[0024] Embodiment two, please refer to Figures 1-7 On the basis of embodiment one, the hot air assembly 500 includes the hydraulic chamber three 501 assembled on the side of the wind power generation chamber 200. The output end of the plurality of blades 300 is bolted with the cam 502. One end of the hydraulic chamber three 501 is connected with the stress rod two 503. The other end of the hydraulic chamber three 501 is connected with the tooth rod 504. When the plurality of blades 300 are in a rotating state, the cam 502 can be rotated, and the cam 502 can extrude the stress rod two 503 and drive the stress rod two 503 to move to the side when the cam 502 is rotated to the stress rod two 503. Cooperating with the hydraulic chamber three 501 connected with the stress rod two 503, the pressure in the hydraulic chamber three 501 increases, driving the tooth rod 504 connected with the hydraulic chamber three 501 to move upward.

[0025] The side of the wind power generation bin 200 is rotationally connected with a gear 505, and the side of the gear 505 is fixedly connected with a torsion spring rod 506. When the toothed rod 504 moves upward, it drives the gear 505 meshed therewith to rotate, so that the gear 505 drives the torsion spring rod 506 fixedly connected therewith to rotate by a certain angle. When the cam 502 moves away from the force receiving rod 2 503, the restriction of the cam 502 to the force receiving rod 2 503 is cancelled, and the restriction on the torsion spring rod 506 is also cancelled. At this time, the torsion spring rod 506 can reverse rotate and reset under its own action. Thus, the torsion spring rod 506 can reciprocate by a certain angle.

[0026] The bottom of the wind power generation bin 200 is provided with a hot air pump 507 with an electric heating mechanism, the side of the hot air pump 507 is provided with a conveying pipeline 508, the top of the conveying pipeline 508 is rotationally connected with a pipeline joint 509, the pipeline joint 509 is located at the side of the torsion spring rod 506 and is in a fixed state with the torsion spring rod 506, and the side of the pipeline joint 509 is provided with an air outlet pipeline 510. The hot air pump 507 with an electric heating mechanism is started to input hot air into the conveying pipeline 508. When the torsion spring rod 506 reciprocates by a certain angle, it drives the pipeline joint 509 fixedly connected therewith to reciprocate, so that the pipeline joint 509 drives the air outlet pipeline 510 provided at the side thereof to reciprocate, and the hot air is uniformly sprayed to each position on the plurality of groups of blades 300 rotated to the position. The outer surfaces of the plurality of groups of blades 300 are prevented from icing, so that the device is more easy to use.

[0027] In use, on the basis of the first embodiment, the hot air pump 507 with an electric heating mechanism is started to input hot air into the conveying pipeline 508. When the plurality of groups of blades 300 are in a rotating state, the cam 502 is driven to rotate. When the cam 502 rotates to the force receiving rod 2 503, it presses the force receiving rod 2 503 and drives the force receiving rod 2 503 to move to the side, cooperates with the hydraulic bin 3 501 slidingly connected with the force receiving rod 2 503, increases the pressure in the hydraulic bin 3 501, drives the toothed rod 504 slidingly connected with the hydraulic bin 3 501 to move upward, drives the gear 505 meshed therewith to rotate, so that the gear 505 drives the torsion spring rod 506 fixedly connected therewith to rotate by a certain angle. When the cam 502 moves away from the force receiving rod 2 503, the restriction of the cam 502 to the force receiving rod 2 503 is cancelled, and the restriction on the torsion spring rod 506 is also cancelled. At this time, the torsion spring rod 506 can reverse rotate and reset under its own action. Thus, the torsion spring rod 506 can reciprocate by a certain angle, drives the pipeline joint 509 fixedly connected therewith to reciprocate, so that the pipeline joint 509 drives the air outlet pipeline 510 provided at the side thereof to reciprocate, and the hot air is uniformly sprayed to each position on the plurality of groups of blades 300 rotated to the position.

When the plurality of groups of blades 300 are in the rotating state, the chain wheel one 602 can be driven to rotate, the chain 603 assembled at the outer side of the chain wheel one 602 is matched, so that the chain wheel two 605 driven to rotate through the transmission connection of the chain 603 and the chain wheel one 602, the chain wheel two 605 drives the reciprocating screw rod 604 fixedly connected therewith to rotate.

[0029] The outer side of the reciprocating screw rod 604 is threadedly connected with a moving seat 606, the top of the moving seat 606 is assembled with a cleaning brush plate 607.
