[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Figures 1 to 4 As shown, an embodiment of the present invention provides an adjustable wind power generation device, the wind power generation device comprising:

[0033] A base 10, wherein the base 10 is hollow;

[0034] An air drive unit 40 is fixedly connected to the upper end of the base 10. The air drive unit 40 includes a core ventilation pipe 41 and an air guide column 42. The core ventilation pipe 41 is a cylindrical structure with an opening at one end. The opening is provided at the end of the core ventilation pipe 41 close to the base 10. Two air guide columns 42 are provided and the two are mirror-imaged. The side of the air guide column 42 close to the core ventilation pipe 41 is arc-shaped. A slit structure with large openings at both ends and a small opening in the middle is formed between the core ventilation pipe 41 and the air guide column 42. The portion of the core ventilation pipe 41 close to the slit is provided with multiple air holes.

[0035] A power generation assembly 50, comprising a generator 52 fixedly connected to the interior of the base 10 and blades 51 located at the mouth of the core ventilation tube 41, wherein the blades 51 are fixedly connected to the rotor shaft of the generator 52;

[0036] a steering assembly 60 , the steering assembly 60 being connected to the air driving unit 40 to drive the air driving unit 40 to rotate;

[0037] The detection component 70 is used to detect wind direction and wind speed. The detection component 70 is connected to a control unit, and the control unit is used to control the steering component 60 to adjust the direction of the slit structure.

[0038] In this embodiment, when generating electricity, wind enters the slit structure from the opening at one end of the slit. According to the Venturi effect, the flow velocity of the fluid increases when passing through the reduced flow cross-section, and the air flow velocity through the slit structure increases. According to Bernoulli's principle, the increase in flow velocity is accompanied by a decrease in fluid pressure, thereby generating a low-pressure area and forming an adsorption effect. Therefore, the air pressure in the slit structure is lower than the external air pressure. The air in the core ventilation pipe 41 enters the slit structure, so that the external air enters the slit structure through the opening of the core ventilation pipe 41 and is discharged from the slit structure. The air entering the core ventilation pipe 41 drives the blades 51 to rotate, thereby driving the generator 52 to rotate, so that The generator 52 generates electricity; during the power generation process, the detection component 70 detects the wind speed and wind direction in real time and sends the detection data to the control unit, and the control unit controls the operation of the steering component 60 according to the detection results. The steering component 60 drives the air driving unit 40 to rotate to adjust the direction of the slit, so that the angle between the air flowing into the slit structure and the wind direction changes. In windy weather, the angle between the slit structure and the wind direction is increased, and in light wind weather, the angle between the slit and the wind direction is reduced, thereby adjusting the pressure difference between the inside and outside of the core ventilation pipe 41, and then adjusting the rotation speed of the blade 51, so that the rotation speed of the blade 51 is maintained within a safe range while maintaining the power generation power of the generator 52.

[0039] The adjustable wind power generation device disclosed in the embodiment of the present invention realizes the flow of air in the core ventilation pipe 41 to drive the power generation component 50 to generate electricity based on the Venturi effect and Bernoulli's principle. The direction of the slit structure on the core ventilation pipe 41 can also be adjusted by the steering component 60 to control the pressure difference inside and outside the core ventilation pipe 41, thereby adjusting the rotation speed of the power generation component 50, so that in windy weather, the power generation component 50 can still maintain a safe rotation speed, so that it can operate safely and generate electricity in windy weather without stopping.
