[0023] In the above structure, after the wind measuring device 6 detects the direction of the wind, it sends a signal to the motor 2 9, prompting the power output shaft of the motor 2 9 to start rotating after receiving the signal. When the motor 2 9 rotates, it drives the gear 1 10 to rotate. Since the gear 10 and the circular gear 3 13 are in a meshing transmission state, when the gear 1 10 rotates, it drives the circular gear 3 13 to rotate on the inner wall of the placement groove 8. When the circular gear 3 13 rotates, it drives the gear 2 12 and the rotating rod 11 to rotate, which makes the circular gear 3 13 more stable during the rotation process. When the circular gear 3 13 rotates, it also drives the connecting plate 14 and the wind turbine body 3 to rotate, thereby adjusting the direction of the blade 5.

[0024] In a preferred embodiment: the power shaft of the wind turbine body 3 is fixedly equipped with blades 5;

[0025] In the above structure, the rotational force of the blades 5 is converted into electrical energy by the wind turbine body 3 , and the wind direction is detected by the wind measuring device 6 .

[0026] In a preferred embodiment, the buffer assembly 7 includes a mounting block 701, a fixing block 702 is fixedly assembled on the inner wall of the mounting block 701, a rotating column 703 is rotatably connected to the inner wall of the fixing block 702, one end of a connecting block 704 is fixedly assembled on the outer wall of the rotating column 703, a circular cylinder 705 is fixedly assembled on the other end of the connecting block 704, one end of a spring 706 is fixedly assembled on the inner wall of the circular cylinder 705, one side of a circular plate 708 is fixedly assembled on the other end of the spring 706, a pressure rod 707 is fixedly assembled on the other side of the circular plate 708, a rotating block 711 is fixedly assembled on the end of the pressure rod 707 away from the circular plate 708, a placing block 709 is provided on the outer wall of the rotating block 711, and a cylinder 710 is rotatably connected to the inner wall of the placing block 709;

[0027] In the above structure, when the wind power tower 2 collapses, the tower body 1 contacts the ground. When the tower body 1 is under pressure, it will prompt the mounting block 701 to move. The movement of the mounting block 701 drives the rotating column 703, the fixed block 702, and the connecting block 704 to apply pressure to the circular cylinder 705. Under the action of pressure, the circular cylinder 705 drives the spring 706 to apply pressure to the circular plate 708, the pressure rod 707 and the rotating block 711. After the rotating block 711 is under pressure, it drives the cylinder 710 to rotate on the inner wall of the placement block 709. After the spring 706 is under pressure, it releases elastic potential energy and drives the mounting block 701 to retract, thereby protecting the wind power tower 2.

[0028] In a preferred embodiment, the rotating block 711 is fixedly assembled with the cylinder 710, the circular plate 708 is slidably connected with the inner wall of the circular cylinder 705, the mounting block 701 is fixedly assembled with the inner wall of the tower body 1, and the placement block 709 is fixedly assembled with the outer wall of the wind power tower 2;

[0029] In the above structure, the buffer assembly 7 is limited and fixed by the tower body 1 and the wind power tower 2, so that the buffer assembly 7 is more stable when placed or operated, the cylinder 710 and the pressure rod 707 are connected by the rotating block 711, and the circular plate 708 is limited by the circular cylinder 705.

[0030] In a preferred embodiment, gear 1 10 and gear 2 12 are both meshed with circular gear 3 13 for transmission, gear 1 10 and gear 2 12 are of the same shape and size, and wind measuring device 6 is electrically connected to motor 2 9;

[0031] In the above structure, when gear 1 10 rotates, it drives circular gear 3 13 to rotate on the inner wall of the placement slot 8. When circular gear 3 13 rotates, it drives gear 2 12 to rotate. Since gear 1 10 and gear 2 12 have the same shape and size, circular gear 3 13 will not get stuck when rotating. The direction of the wind is monitored by the wind measuring device 6, and after the wind measuring device 6 monitors the direction of the wind speed, it sends a signal to motor 2 9.

[0032] In a preferred embodiment, there are four groups of buffer components 7 , and the four groups of buffer components 7 are respectively located on the outer wall of the wind power tower 2 ;

[0033] In the above structure, four groups of buffer components 7 are used to protect the four directions of the wind power generation tower 2, thereby reducing the damage when the wind power generation tower 2 collapses.

[0034] Working principle: After the wind direction is detected by the wind measuring device 6, a signal is sent to the motor 2 9, so that the power output shaft of the motor 2 9 starts to rotate after receiving the signal, and the rotation of the motor 2 9 drives the gear 1 10 to rotate. Since the gear 1 10 and the circular gear 3 13 are meshed with each other for transmission, when the gear 1 10 rotates, it drives the circular gear 3 13 to rotate on the inner wall of the placement slot 8. When the circular gear 3 13 rotates, it drives the gear 2 12 and the rotating rod 11 to rotate together, which makes the circular gear 3 13 more stable during the rotation process. At the same time, the rotation of the circular gear 3 13 will also drive the connecting plate 14 and the wind turbine body 3 to rotate, thereby achieving the blade 5 is adjusted in the direction of rotation. When the wind power tower 2 collapses, the tower body 1 contacts the ground. The tower body 1 is subjected to pressure and drives the mounting block 701 to move. The movement of the mounting block 701 drives the rotating column 703, the fixed block 702, and the connecting block 704 to apply pressure to the circular cylinder 705. The circular cylinder 705 is subjected to pressure and applies pressure to the spring 706, the circular plate 708, the pressure rod 707, and the rotating block 711. The rotating block 711 is subjected to pressure and drives the cylinder 710 to rotate on the inner wall of the placement block 709. The spring 706 releases its elastic potential energy after being subjected to pressure, driving the mounting block 701 to retract, thereby protecting the wind power tower 2.
