[0031] A second vertical rod 10 is provided in the device box 2, a second support is provided on the outer periphery of the second vertical rod 10, and one end of the second support is fixedly connected to the inner wall of the device box 2; the top of the second vertical rod 10 is connected to the first transmission assembly, and the rotating first vertical rod 8 drives the second vertical rod 10 to transmit through the first transmission assembly; a first transmission plate 12 is fixedly provided at the bottom of the second vertical rod 10;

[0032] A shaft 6 is rotatably arranged at the center of the bottom of the turntable 3, a second transmission plate 13 is fixedly sleeved on the shaft 6, a third gear 15 is fixedly arranged at the bottom of the shaft 6, and a same set of transmission belts 14 is sleeved between the first transmission plate 12 and the second transmission plate 13, wherein the area of ​​the first transmission plate 12 is larger than that of the second transmission plate 13;

[0033] An output rod 19 is provided on the top of the generator 4, and a second transmission assembly is provided in the device box 2. The rotation of the third gear 15 drives the output rod 19 to rotate;

[0034] In this embodiment, the wind drives the rotation, the fan blade assembly 5 drives the rotating disk 3 to rotate synchronously, the rotating disk 3 drives the first inner gear ring 7 to rotate, the first inner gear ring 7 drives the first vertical rod 8 to rotate through the first gear 801, the first vertical rod 8 drives the second vertical rod 10 to rotate through the first transmission assembly, the second vertical rod 10 drives the first transmission plate 12 to rotate, the first transmission plate 12 drives the second transmission plate 13 to rotate through the transmission belt 14, the second transmission plate 13 drives the shaft rod 6 to rotate, the shaft rod 6 drives the output rod 19 of the generator 4 to rotate through the third gear 15 and the second transmission assembly;

[0035] Among them, when the first inner gear ring 7 drives the first gear 801 to rotate, the first speed increase will be performed in this process; specifically, since the diameter of the first inner gear ring 7 is larger than the diameter of the first gear 801, when the first inner gear ring 7 drives the first gear 801 to rotate, the rotation speed of the first gear 801 will be greater than the rotation speed of the first inner gear ring 7, and then the rotation speed of the first vertical rod 8 will be greater than the rotation speed of the blade assembly 5, which is the first speed increase; the first vertical rod 8 drives the second vertical rod 10 to rotate through the first transmission assembly;

[0036] When the first transmission plate 12 drives the second transmission plate 13 to rotate through the transmission belt 14, a second speed increase will be performed in this process; specifically, since the diameter of the first transmission plate 12 is larger than the diameter of the second transmission plate 13, when the first transmission plate 12 drives the second transmission plate 13 to rotate through the transmission belt 14, the linear speeds of the two are consistent due to the limitation of the transmission belt 14, so the rotation speed of the second transmission plate 13 will be lower than the rotation speed of the first transmission plate 12, and then the rotation speed of the shaft rod 6 will be greater than the rotation speed of the second vertical rod 10, which is the second speed increase;

[0037] Therefore, when the fan blade assembly 5 is affected by wind and rotates to drive the output rod 19 on the generator 4 to rotate, it will go through the first speed increase and the second speed increase during the transmission process.

When the first vertical rod 8 rotates, the first vertical rod 8 drives the second inner gear ring 9 to rotate, and the second inner gear ring 9 drives the second vertical rod 10 to rotate through the second gear 11. In addition, since the diameter of the second inner gear ring 9 is larger than the diameter of the second gear 11, and because the second inner gear ring 9 is meshed with the second gear 11, the linear speeds of the two are consistent. Then, when the rotation speed of the second gear 11 is greater than the rotation speed of the second inner gear ring 9, the rotation speed of the second vertical rod 10 is finally made greater than the rotation speed of the first vertical rod 8, completing the third speed increase.
