When the drive motor 22 is started, the drive motor 22 drives the lead screw 10 to rotate, the lead screw 10 drives the moving block 11 to move, the moving block 11 drives the two first support plates 12 to move synchronously, the two first support plates 12 drive the same second rotating shaft 13 to move, the second rotating shaft 13 drives the first fixing block 16 to move, the first fixing block 16 drives the first support block 17 to move, the first support block 17 drives the slider 18 to move, the second support block 19 drives the second fixing block 20 to move, and the second fixing block 20 drives the third rotating shaft 15 to move, facilitating the adjustment of the elevation angle of the wind turbine body 8 according to the wind direction, and facilitating the improvement of wind energy utilization rate and power generation reliability. When the second stepper motor 52 is started, the second stepper motor 52 is powered by the sliding connection and continuous contact of the two contact blocks. The second stepper motor 52 drives the second rotating shaft 46 to rotate, the second rotating shaft 46 drives the sun gear 47 to rotate, the sun gear 47 simultaneously drives the three planet gears 49 to rotate, the three planet gears 49 respectively drive the three third rotating shafts 48 to rotate, and the three planet gears 49 drive the same internal gear ring 50 to rotate, achieving speed reduction, converting the high-speed low-torque of the second stepper motor 52 into low-speed high-torque. At the same time, the second stepper motor 52 drives one of the two first transmission shafts 28 to rotate, one of the two first transmission shafts 28 drives the first sprocket 41 to rotate, the first sprocket 41 drives the second sprocket 43 to rotate through the chain 42, the second sprocket 43 drives the other of the two first transmission shafts 28 to rotate, and the two first transmission shafts 28 both drive the two first spiral bevel gears 29 and the two second bevel gears 27 to rotate, the two second bevel gears 27 both drive the two first bevel gears 26 to rotate, the two first bevel gears 26 both drive two of the multiple rotating shafts 25 to rotate. At the same time, the two first spiral bevel gears 29 both drive the two second spiral bevel gears 30 to rotate, the two second spiral bevel gears 30 both drive the two second transmission shafts 31 to rotate, the two second transmission shafts 31 both drive the two third bevel gears 32 to rotate, the two third bevel gears 32 both drive the two fourth bevel gears 33 to rotate, the two fourth bevel gears 33 both drive the two fifth bevel gears 34 to rotate, the two fifth bevel gears 34 both drive the two third transmission shafts 35 to rotate, the two third transmission shafts 35 both drive the two third spiral bevel gears 36 to rotate, the two third spiral bevel gears 36 both drive the two fourth spiral bevel gears 37 to rotate, and the two fourth spiral bevel gears 37 both drive the two fourth transmission shafts 38 to rotate,Both of the two fourth transmission shafts 38 drive the two sixth bevel gears 39 to rotate.

The multiple rotating shafts 25 drive the blades to rotate respectively, which is convenient for dynamically adjusting the blade angles, further adapting to the wind speed change, and improving the wind energy utilization rate and power generation reliability at the same time.

[0065] Embodiment 2

[0066] The difference between this embodiment and Embodiment 1 is that: an anemometer is fixedly installed on the top of the base 1, and the anemometer is used to detect the magnitude of the wind, so as to pre-adjust the angle of the blade according to the magnitude of the wind, reduce the impact of dynamic load, and avoid damaging the blade.

[0067] Embodiment 3

[0068] The difference between this embodiment and Embodiment 1 is that: micro-grooves are opened on the blade surface. Through the setting of the micro-grooves, the flow separation effect can be delayed to enhance the starting performance at low wind speeds. At the same time, a centrifugal weight self-adjusting mechanism is installed at the blade root. The centrifugal weight is connected to the wind turbine body 8 and generates centrifugal force as the rotational speed increases. When the rotational speed exceeds the threshold, the centrifugal force overcomes the spring pre-tightening force, driving the weight to move radially outwards, triggering the limit switch or mechanical link to act, and automatically increasing the blade centrifugal force to limit the rotational speed when encountering strong winds, avoiding over-speed damage.

[0069] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
