[0040] Working principle: The device is fixed on the main base 1, which can be installed in the form of a cylindrical tower, a column or a roof according to the installation scene, and needs to meet the installation requirement that the height from the bottom end of the main base 1 to the wind rotor 6 is higher than the opening radius of the flipper 8, to provide stable support for the overall structure; the fixed cylinder 2 is fixedly installed above the main base 1, the rotating cylinder 3 is rotatably nested in the fixed cylinder 2, to form a basic structure for horizontal rotation adjustment; the U-shaped frame 4 is arranged on the top of the rotating cylinder 3, the swing frame 5 is rotatably installed between the U-shaped frames 4 through a rotating shaft, the swing cavity 12 reserved in the rotating cylinder 3 provides space for the pitch swing of the swing frame 5, and together they constitute a "horizontal and pitch" dual-dimension adjustment frame of the device.
[0041] Wind direction tracking and angle self-adaptive adjustment: Horizontal wind direction tracking: the horizontal wind direction sensors 23 installed on the upper end of the swing frame 5 and the outer side wall of the U-shaped frame 4 detect the included angle between the horizontal wind direction and the axis of the wind rotor 6 in real time; when the wind direction deviates, the signal is transmitted to the control system to trigger the wind direction tracking motor 10 fixedly installed on the lower end face of the fixed cylinder 2 to start, the driving end of the wind direction tracking motor 10 is directly connected to the lower end face of the rotating cylinder 3, the rotating cylinder 3 is driven to rotate around the axis of the fixed cylinder 2, and then the U-shaped frame 4, the swing frame 5 and the wind rotor 6 are synchronously rotated, until the axis of the wind rotor 6 is collinear with the horizontal wind direction, to realize the self-adaptation of the horizontal wind direction. Pitch angle adjustment: the vertical wind direction sensor 22 fixedly installed on the U-shaped frame 4 detects the inclination angle of the wind relative to the ground in real time, after the detection signal is fed back, the pitch adjustment motor 11 fixedly installed on the U-shaped frame 4 starts, the driving end of the pitch adjustment motor 11 is directly connected to the side wall of the swing frame 5, the swing frame 5 is driven to pitch around the rotating shaft between the U-shaped frames 4, and then the included angle between the wind rotor 6 and the ground is adjusted, so that the wind rotor 6 always adheres to the inclined wind direction, to maximize the capture of wind energy, and to avoid the lateral impact force of the inclined wind on the structure.
[0042] Wind energy capture and electric energy conversion: Wind energy capture and transmission: The wind rotor 6 is rotatably installed inside the swing frame 5, and three fan blade holders 7 are evenly rotatably installed on the wind rotor 6 at an angle of 120°. A flipper 8 is installed on each fan blade holder 7 through a flip motor 9.

Power regulation and electric energy generation: The input end of the clutch 17 fixedly installed inside the swing frame 5 is fixedly connected with the transmission driven bevel gear 16.

[0045] Signal and power transmission: all rotating structures of the device, such as the contact surface of the rotating cylinder 3 and the fixed cylinder 2, and the rotating shaft of the swing frame 5 and the U-shaped frame 4, adopt the "conductor ring and brush" structure. In addition to the output cable of the generator 13, the control signals and power supply of the wind direction tracking motor 10, the pitch adjustment motor 11, the overturning motor 9, and the blade direction adjustment motor 18 are all transmitted through this structure to ensure that the control signals are not interrupted and the power supply is stable during the horizontal rotation and pitch swing of the device, ensuring the cooperative operation of each structure.
