Symmetrically arranged on both sides of the adjusting wheel 103a-2, which has two advantages, namely, the mass distribution of the speed changing part 103a is uniform, and deflection force is not generated during rotation; secondly, since there is a certain resistance when the adjusting wheel 103a-2 rotates, the adjusting wheel 103a-2 rotates better by providing two first driving members 103a-3 to increase the driving force. The adjusting wheel 103a-2 is connected with the fastening wheel 103a-5, an archimedes spiral gear 103a-21 is arranged on the side face of the adjusting wheel 103a-2, threads 103a-41 matched with the archimedes spiral gear 103a-21 are arranged on one side face of the adjusting wheel 103a-4, a breaking gear 103a-42 is connected on the other side face of the adjusting wheel, a plurality of the breaking gears 103a-42 are arranged on the adjusting wheel 103a-4, and a plurality of the breaking gears 103a-42 can be spliced into a complete gear. In this embodiment, the broken gears 103a-42 are provided with four, so that each broken gear 103a-42 is a full gear of one-fourth size.
Preferably, the fastening wheel 103a-5 is provided with a plurality of moving grooves 103a-51 for the adjusting rod 103a-4 to move up and down, and the breaking gear 103a-42 and the screw 103a-41 are respectively disposed at two sides of the adjusting rod 103 a-4.
Further, the tensioning device 103a-7 includes a tensioning pulley 103a-71 engaged with the chain 103a-6, a fixing plate 103a-72 fixing the tensioning pulley 103a-71, and a spring 103a-73 pulling the tensioning pulley 103 a-71. The fixing plate 103a-72 is provided with a sliding groove 103a-74, a sliding block 103a-75 is arranged in the sliding groove 103a-74, the tensioning wheel 103a-71 is fixed on the sliding block 103a-75, and the spring 103a-73 is arranged in the sliding groove 103a-74 and is connected with the sliding block 103 a-75.
Preferably, the sliding grooves 103a-74 are arranged obliquely, and the oblique direction is the connecting line direction of the tensioning wheels 103a-71 and the rotating shaft of the speed increasing gear box 103 b. The reason for the inclined arrangement is that the space in the fairing 106 is limited, so that the distance between the broken gear 103a-42 and the transmission shaft of the speed-increasing gear box 103b is not too large, and when the broken gear 103a-42 is enlarged, if the tension wheel 103a-71 moves horizontally, the tension wheel 103a-71 may be in contact with the broken gear 103a-42 to cause teeth, so that the sliding groove 103a-74 is inclined, so that the broken gear 103a-42 moves obliquely downwards, thereby realizing tensioning of the chain 103a-6, and preventing the tension wheel 103a-71 from contacting the broken gear 103 a-42. The reason that the oblique direction is the connection line direction of the tension wheels 103a-71 and the rotating shaft of the speed increasing gear box 103b is that the contact tooth number of the chain 103a-6 and the rotating shaft of the speed increasing gear box 103b can be ensured to be consistent, and the phenomenon that the contact tooth number of the rotating shaft of the speed increasing gear box 103b and the chain 103a-6 is reduced to cause sliding teeth does not occur. The rotation axis of the speed increasing gear box 103b is provided with a gear which is engaged with the chains 103 a-6.
Further, the wind power generation module 100 further comprises a fairing 106, a nacelle 107 and a tower 108, the fairing 106 is rotationally engaged with the nacelle 107, the nacelle 107 is rotationally engaged with the tower 108, the hub 102 and the speed changing member 103a are both arranged in the fairing 106, and the tensioning device 103a-7 is fixed on the nacelle 107.

The braking device 110 is installed in the speed increasing gear box 103b and the generator 104, which limits the transmission shaft between the generator 104 and the speed increasing gear box 103b to perform a braking function, and the braking device 110 may be implemented by adopting the prior art.
In summary, after the control module 300 receives the wind speed and wind direction information detected by the monitoring module 200, the yaw device 109 is controlled to rotate the nacelle 107 to the windward direction, the pitch device 105 is used to make the blades 101 at the optimal pitch angle, at this time, the region where the broken gear 103a-42 should be located is determined according to the wind speed and the rotation speed of the blades, the first driving member 103a-3 is used to drive the adjusting wheel 103a-2 to rotate, so that the broken gear 103a-42 is located in the region, and when the rotation speed of the blades and the rotation speed of the generator meet the requirements, the first driving member 103a-3 is stopped.
Through the system provided by the invention, the transmission ratio of the speed changing unit 103 can be changed to be adjustable, when the wind force is smaller, the transmission ratio is reduced, the generator 104 can be driven to rotate, when the wind speed is larger, the transmission ratio is increased, the rotating speed of the blades 101 is reduced, the generating capacity is increased, namely, the blades 101 are protected, the generating capacity is improved, the braking device 110 is not required to brake at any time, the service life of the braking device 110 is prolonged, and the plurality of blades can be controlled to rotate only by arranging one pitch device 105, so that the cost is saved, and the space in the fairing 106 is saved.
It should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered in the scope of the claims of the present invention.
