The first gear 623 consists of two sets of gears 6231, 6232, 6233, and 6234 arranged at intervals, and the first gear 623 rotates as the first pinion 622 rotates.

[0051] Referring again to Figure 1 and in conjunction with Figures 9 to 13, the second transmission device 63 includes a second rotating shaft 631, a clutch 632 pivotally connected to one end of the second rotating shaft 631, a second transmission gear 633 pivotally connected to the second rotating shaft 631 and located below the clutch 632, a sleeve 634 sleeved on the second rotating shaft 631 and located between the clutch 632 and the second transmission gear 633, and a first large gear set 635 pivotally connected to the other end of the second rotating shaft 631. More specifically, the clutch 632 includes an upper housing 6321, a lower housing 6322 for housing the upper housing 6321, a bushing 6323 axially connecting the upper housing 6321 and the lower housing 6322 and having a square shaft hole 6324, and a plurality of counterweights 6325 respectively disposed between the upper housing 6321 and the lower housing 6322. The second gear 633 meshes with the first gear 623. The second gear 633 consists of two sets of gears 6331, 6332, 6333, and 6334 arranged at intervals. The second gear 633 has a square gear shaft hole 6335 inside. When one of the gears 6331, 6332, 6333, or 6334 of the second gear 633 rotates, it changes its rotation direction to the opposite direction to that of one of the gears 6231, 6232, 6233, or 6234 of the first gear 623. The sleeve 634 is a hollow tube into which the bushing 6323 is inserted. The first large gear set 635 includes a large gear 6351, a shaft 6352 connected to one end of the large gear 6351, a pressure plate 6353 connected to one end of the shaft 6352, and a spring 6355 sleeved between the pressure plate 6353 and the second gear 633. The other end of the shaft 6352 is shaped like a square rod 6354 to fit the square gear shaft hole 6335 and the square shaft hole 6324, so that the square rod 6354 passes through the spring 6355, the square gear shaft hole 6335 of the second gear 633, the sleeve 634, and the bushing 6 of the clutch 632. 323, and the second rotating shaft 631 is inserted into the shaft 6352 and the square rod 6354, and connected to the upper housing 6321 at one end of the second rotating shaft 631 through a cover 6356; when rotating at high speed, the plurality of counterweights 6325 of the clutch 632 will gradually push outward with inertia, and at the same time push the lower housing 6322 downward (as shown in Figures 15A to 15C), the lower housing 6322 pushes the sleeve 634 and at the same time pushes the second gear 633 downward, so that the second gear 633 successively meshes with the first gear 623 to change speed.

[0052] The second power device 64 includes a second rotating rod 641 that passes through the bracket 234 and a second power gear 642 that meshes with the large gear 6351. The second power gear 642 is shaft-connected to one end of the second rotating rod 641 and rotates with the large gear 6351, thereby driving the second rotating rod 641 to rotate as well.

[0053] The power generation device 7 is rotatably connected to the second power device 64 to drive the power generation device 7 to rotate, so that the second power device 64 connects the power generated by the wind turbine unit 3 to the power generation device 7 to generate electricity, as shown in Figure 13, so that the clutch 632 drives the second speed change device 63 to change speed as the rotation speed increases, thereby increasing the power generation efficiency.

[0054] Referring again to Figures 1, 8 to 13 and in conjunction with Figures 14A to 15C, the wind power generation device 1 of the present invention, composed of the aforementioned components, in actual use, when the blade 322 of the blade assembly 32 is rotated by wind force, the blade 322 drives the transmission shaft 321 to rotate, and drives the disc brake 45, the driven bevel gear 326, and the front brake drive ring 41 on the transmission shaft 321 to rotate together. The driven bevel gear 326 drives the drive bevel gear 612 to mesh and rotate, transmitting the rotational power downward to the first rotating rod 611 to rotate, causing the first rotating rod 611 to drive the first power gear 613 to rotate, with the help of the first... A power gear 613 rotates, driving the first pinion 622, which meshes with it, to rotate. The first pinion 622 drives the first rotating shaft 621 to rotate, which in turn drives the first transmission gear 623 to rotate. The fourth gear 6234 of the first transmission gear 623 drives the fourth gear 6334 of the meshing second transmission gear 633 to rotate (as shown in Figure 16A). The fourth gear 6334 of the second transmission gear 633 drives the clutch 63 at one end of the connected second rotating shaft 631 to rotate. Simultaneously, as shown in Figures 15A to 15C, when the second transmission gear 613 rotates... When the clutch 632 at one end of the shaft 631 rotates at high speed due to wind power, the plurality of counterweights 6325 of the clutch 632 will gradually push outward due to inertia, simultaneously pushing the lower housing 6322 downward (as shown in Figures 15A to 16A). When the lower housing 6322 pushes the sleeve 634 downward, it simultaneously pushes the second gear 633 downward and compresses the spring 6355 more and more, so that the third gear 6333 of the second gear 633 meshes with the third gear 6233 of the first gear 623 (as shown in Figure 16B), and so on, the second gear 633 of the second gear 633 meshes with the third gear 6233 of the first gear 623. 32 meshes with the second gear 6232 of the first gear 623 (as shown in Figure 16C). Finally, the first gear 6331 of the second gear 633 meshes with the first gear 6231 of the first gear 623 (as shown in Figure 16D) to reduce speed. When the second rotating shaft 631 rotates, the large gear 6351 on the second rotating shaft 631 meshes and drives the second power gear 642 on the second rotating rod 641 to rotate, and transmits power to the generator 7 to generate electricity. The transmission unit 6 forms a speed reduction effect, thereby achieving higher torque to drive the generator 7.

[0055] Please refer to Figures 8 to 13. When the blade 322 of the blade assembly 32 is subjected to less wind force, after the transmission unit 6 decelerates, the multiple counterweights 6325 of the clutch 632 at one end of the second rotating shaft 631 will lose inertia and be subjected to gravity and the restoring force of the compressed spring 6355 as the deceleration occurs, returning the multiple counterweights 6325 to their original positions inside the lower housing 6322, causing the lower housing 6322 to be pushed upwards.

[0056] Please refer to Figures 7 and 8, and in conjunction with Figures 14A and 14B. When the wind speed is too strong, the wind force pushes the pusher 4322 of the brake plate 432, which in turn drives the other end of the pusher 4322 to be pressed by the compression spring 332. This causes the rear brake drive ring 42 to gradually fix towards the front brake drive ring 41. When the rear brake drive ring 42 is pushed, it simultaneously pushes the disc brake disc 45, which is electrically connected to the disc brake pusher 44, to start braking and deceleration, thereby fixing the drive shaft 321 and stopping the rotation of the blades 322 of the blade assembly 32. At this time, the solenoid valve 433 locks the brake plate 432 at its maximum angle, preventing the rear brake drive ring 42 from being pushed back by the compression spring 332, and locking the rear brake drive ring 42 in the fully braked position, thus causing the front brake drive ring 41 to engage. The rotating ring 41 cannot rotate, thus pushing the rear brake drive ring 42 back, locking the blade 322 of the blade assembly 32 in place. When the wind speed decreases, the pusher 4322 reduces the wind force, causing the other end of the brake plate 432 to automatically return to its original position via the compression spring 332, driving the separation between the rear brake drive ring 42 and the front brake drive ring 41, thereby allowing the blade assembly 322 to rotate. When the blade 322 of the 2 rotates, and the rear brake drive ring 42 separates from the front brake drive ring 41, the disc brake pusher 44 is not pushed by the rear brake drive ring 42, the disc brake pusher 44 is released, and the disc brake disc 45 electrically connected to the disc brake pusher 44 is notified to release. The drive shaft 321 will not be fixed by the disc brake disc 45, so that the blade 322 of the blade assembly 32 can continue to rotate.
