After the power generation component is installed, the mounting frame 120 is placed in a longitudinal position and fixed, and there is no need to install the power generation component at high altitude, which greatly facilitates the power generation component and improves the installation efficiency.

[0033] Preferably, a fastening cable 130 is further included, wherein the first end of the fastening cable 130 is connected to the mounting frame 120 and the second end is arranged at a preset position. By arranging the fastening cable 130, after the mounting frame 120 is placed in the longitudinal position, the fastening cable 130 is used to improve the stability of the frame fixation.

[0040] Specifically, the rotating frame includes a rotating base 311 rotatably connected to the top of the frame, and the rotating base 311 is transmission-connected to the generator 340.

The number of sails 320 is equal to the number of large arms 312 and corresponds one to one, and the sails 320 are arranged at the second ends of the large arms 312.

[0041] When in use, the wind acts on the sail 320 to drive the rotating seat 311 to rotate through the large arm 312, thereby driving the generator 340 to rotate, thereby achieving the purpose of generating electricity.

[0042] Specifically, the second end of the arm 312 is provided with a support arm 313, which is fixedly connected to the second end of the arm 312 and extends freely in the longitudinal direction, and the sail 320 is arranged on the support arm 313.

[0045] By setting up an angle adjustment component, the angle between the sail 320 and the wind direction can be adjusted according to the position of the sail 320 and the wind direction, so as to achieve the purpose of converting wind energy from any wind direction into electrical energy. At the same time, the wind force difference received by the sails 320 on both sides can also be increased, thereby achieving the purpose of improving the conversion efficiency.

[0046] Specifically, the angle adjustment assembly includes a traction rope 331 , a first end of the traction rope 331 is connected to the sail 320 , and a second end of the traction rope 331 is connected to the reeling mechanism.

[0047] When in use, the reeling length of the traction rope 331 is adjusted by the reeling mechanism according to the position of the sail 320 and the direction of the wind, thereby achieving the purpose of changing the angle of the sail 320 .

[0048] Specifically, Figure 5-6 As shown, the angle adjustment component is used to adjust the angle between the sail 320 and the wind direction according to the position of the sail 320 and the wind direction, so that there is always a wind force difference between the wind forces received by the sails 320 on the left and right sides, so that the motor 340 can be driven by the upper arm 312 to rotate and generate electricity, thereby achieving the purpose of generating electricity.

[0049] Preferably, a wind direction sensor is also included to achieve the purpose of confirming the wind direction. Preferably, a position sensor is also included to achieve the purpose of confirming the position of the sail 320.
