[0075] When the wind speed decreases, the lift at the tail of the tail fin 622 decreases, the tail end of the rudder rod 621 is displaced downward under the action of gravity, thereby deflecting the assembly shell 6 by a certain angle, the transmission shell 1 and the impeller module 4 provided on the assembly shell 6 are also deflected, so as to increase the windward projection area of the blade 41 and improve the wind energy conversion efficiency of the impeller module 4; and with the increase of the deflection angle of the assembly shell 6, the distance between the moving magnet 535 and the fixed magnet 533 also increases, and the attraction between the moving magnet 535 and the fixed magnet 533 decreases, so that the moving magnet 535, the telescopic shaft 534, the connecting bracket 536 and the movable shaft sleeve 538 are reset along the axial direction of the unit main shaft 611 under the elastic force of the reset spring 537; with the decrease of the wind speed, the rotation speed of the transmission shell 1 also decreases, and the centrifugal force received by the flying rod 31 also decreases, so that the flying rod 31 drives the telescopic shell 32 and the transmission shaft sleeve 2 to slide along the axial direction of the unit main shaft 611 under the action of gravity, and finally makes the transmission shaft segment 612 inserted into the transmission cavity 21 of the transmission shaft sleeve 2 under the magnetic force between the first magnet 539 and the second magnet 540, so that a power transmission path is formed between the impeller module 4 and the generator 61, and the kinetic energy generated by the impeller module 4 can be transmitted to the generator 61 for power generation; secondly, in the process of sliding of the telescopic shell 32 towards the transmission shaft segment 612, the rack 43 drives the blade 41 to reverse and turn by a certain angle through meshing with the gear 42, so as to improve the wind energy utilization coefficient of the impeller module 4.

[0077] 1、The device drives the unit main shaft 611 to rotate by setting the transmission shaft segment 612 and the transmission shaft sleeve 2 on the unit main shaft 611, and drives the generator 61 to operate, when the wind speed is too high, the load module 3 controls the transmission shaft sleeve 2 and the transmission shaft segment 612 to be separated to cut off the power transmission path between the impeller module 4 and the generator 61, so as to avoid overloading of the generator 61, compared with the scheme of braking the power generation equipment in the prior art, the scheme effectively reduces the degree of wear and tear of the parts during the operation of the equipment, prolongs the service life of the parts, reduces the maintenance cost of the equipment, and solves the defects in the prior art.

[0079] 3、The device is provided with the ball shaft assembly 53 and the tail rudder assembly 62, so that when the wind speed is too high, the assembly shell 6 tends to be in a vertical state, the windward projection area of the blade 41 is reduced, the wind energy conversion efficiency of the impeller module 4 is reduced, the frictional resistance between the inner surface of the semispherical convex groove 531 and the outer surface of the spherical convex block 532 is increased under the magnetic force between the permanent magnet 533 and the moving magnet 535, and the structural stability of the assembly shell 6 is further enhanced; meanwhile, the distance between the first magnet 539 and the second magnet 540 is increased under the magnetic force between the permanent magnet 533 and the moving magnet 535, the attraction between the two is weakened, the magnetic force constraint on the transmission shaft sleeve 2 is released, the transmission shaft sleeve 2 is separated from the transmission shaft section 612 under the centrifugal force of the flying rod 31, so as to cut off the power transmission path between the impeller module 4 and the generator 61, and prevent the generator 61 from being overloaded.
