Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-9, an embodiment of the present invention is: a wind power generation device that is convenient for disassembly and assembly, including a tower 1, the tower 1 is used to install the main body of the wind power generation device, an adjustment shaft 2 is slidably connected to the circumferential surface of the tower 1, a coupling shaft 3 is fixedly connected to the inner surface of the adjustment shaft 2, a rotating device 8 is arranged above the tower 1, the rotating device 8 is used to adjust the angle of the wind power generation device, a positioning device 9 is arranged above the tower 1, the positioning device 9 is used for quick and stable installation and disassembly of the device, a support plate 5 extends around the tower 1 to increase the support area of the tower 1, making the device more stable during wind power generation, and the support plate 5 can be supported by a support rod 10 after it is unfolded, improving the support strength of the device and further enhancing the stability during wind power generation. The coupling shaft 3 includes a torsion shaft 4, the torsion shaft 4 is hinged to the circumferential surface of the coupling shaft 3, the bottom end of the torsion shaft 4 is fixedly connected to a support plate 5, a convex shaft 6 is fixedly connected to the side of the support plate 5 close to the tower 1, a convex shaft 7 is fixedly connected to the bottom end of the circumferential surface of the tower 1, the coupling shaft 3 further includes a support rod 10, the support rod 10 is hinged to the inner surface of the convex shaft 6, a first card slot 11 is opened on the circumferential surface of the tower 1, a trapezoidal clamping block 12 is slidably connected to the inner surface of the first card slot 11, an annular inner inclined groove 13 is opened on the lower surface of the adjustment shaft 2, the bottom end of the support rod 10 is hinged to the inner surface of the convex shaft 7, and a torsion spring 1 is arranged at the hinge between the support rod 10 and the convex shaft 7. A first spring is arranged between the trapezoidal clamping block 12 and the first card slot 11. The upper surface of the adjustment shaft 2 abuts against the lower surface of the trapezoidal clamping block 12. The trapezoidal clamping block 12 pops out of the first card slot 11 to limit the adjustment shaft 2, preventing the adjustment shaft 2 from moving upward and preventing the support plate 5 from loosening during wind power generation. When the support rod 10 resets, it pulls the support plate 5 to retract and close to the tower 1 through the convex shaft 6. When the support plate 5 is close to the tower 1, it pushes the adjustment shaft 2 upward, thereby reducing the area of the device and facilitating storage and movement.

[0024] Working principle: Place the tower 1 on a plane, then push the adjustment shaft 2 downward. The adjustment shaft 2 drives the coupling shaft 3 to move downward, and the coupling shaft 3 drives the torsion shaft 4 to move downward. During this process, the bottom end of the support plate 5 contacts the plane, and its top end moves downward under the influence of the torsion shaft 4, so that the support plate 5 expands around the tower 1, increasing the support area of the tower 1 and making the device more stable during wind power generation. At the same time, the support rod 10 is connected to the tower 1 and the support plate 5 through the first convex shaft 6 and the second convex shaft 7. When the support plate 5 expands, it squeezes the support rod 10 to rotate downward along the axis of the second convex shaft 7. Furthermore, after the support plate 5 expands, it can be supported by the support rod 10, improving the support strength of the device and further enhancing the stability during wind power generation. When the adjustment shaft 2 moves downward, the annular inner inclined groove 13 formed on its lower surface contacts the inclined surface of the first trapezoidal block 12 and is pushed into the first clamping groove 11 through the guidance of the inclined surface. After the first trapezoidal block 12 retracts into the first clamping groove 11, it squeezes the first spring, causing the first spring to contract. After the adjustment shaft 2 continues to move downward, the elastic reset effect of the first spring drives the first trapezoidal block 12 to pop out of the first clamping groove 11 and limit the adjustment shaft 2, preventing the support plate 5 from loosening during wind power generation. When the device needs to be stored, press the first trapezoidal block 12 into the first clamping groove 11, so that the adjustment shaft 2 loses its limit. At this time, the elastic reset effect of the first torsion spring drives the support rod 10 to rotate and reset to fit the circumferential surface of the tower 1. When the support rod 10 resets, it pulls the support plate 5 to retract and close to the tower 1 through the first convex shaft 6. When the support plate 5 is close to the tower 1, it pushes the adjustment shaft 2 upward, thereby reducing the area of the device and facilitating storage and movement.

The conical part 86 and the clamping shaft 87 are inserted into the second groove 85, so that the generator housing 84 is quickly connected to the rotating part 83. On the contrary, the generator housing 84 can be quickly separated from the rotating part 83, which is convenient for storage, and there is no need to repeatedly install and separate the rotating part 83 from the tower 1, avoiding the wear of the metal rotating shaft 82 during the installation and separation process, resulting in the loosening of the device during rotation and affecting the stability of the device. The rotating device 8 further includes a connecting rod 811, the connecting rod 811 is fixedly connected to the upper surface of the adjusting shaft 2, the top end of the connecting rod 811 is fixedly connected with a sliding ring 812, a turning key 813 is hinged to the upper surface of the sliding ring 812, a trapezoidal pressing block 814 is fixedly connected to the side of the turning key 813 close to the tower 1, the clamping shaft 87 abuts against the inner surface of the second groove 85, a second spring is arranged between the trapezoidal clamping block 810 and the second clamping groove 88, the clamping shaft 87 abuts against the inner surface of the through groove 89, the bottom surface of the rotating part 83 abuts against the top surface of the tower 1, the top conical surface of the conical part 86 abuts against the inner inclined surface at the top end of the rotating part 83, the inner surface of the sliding ring 812 is slidably connected to the circumferential surface of the tower 1, a second torsion spring is arranged at the hinge between the turning key 813 and the sliding ring 812. After the trapezoidal clamping block 810 is inserted into the through groove 89, the rotating part 83 can drive the generator housing 84 to rotate. The trapezoidal pressing block 814 is inserted into the through groove 89 and presses the trapezoidal clamping block 810, so that the trapezoidal clamping block 810 retracts into the second clamping groove 88. At this time, the clamping shaft 87 can be quickly pulled out of the second groove 85, thereby improving the convenience of disassembling the generator housing 84.

[0026] Working principle: When the device needs to adjust the angle according to the wind direction, rotate the rotating part 83. The rotating part 83 rotates in the first groove 81 through the metal rotating shaft 82, so as to conform to the wind direction, improve the power generation efficiency of the device. Insert the generator housing 84 into the second groove 85 through the conical part 86 and the clamping shaft 87, so that the generator housing 84 is quickly connected to the rotating part 83. On the contrary, the generator housing 84 can be quickly separated from the rotating part 83, which is convenient for storage, and there is no need to repeatedly install and separate the rotating part 83 from the tower 1, avoiding wear of the metal rotating shaft 82 during the installation and separation process, which may cause looseness of the device during rotation and affect the stability of the device. When the clamping shaft 87 is inserted downward into the second groove 85, it drives the trapezoidal clamping block two 810 to move downward. When the trapezoidal clamping block two 810 moves downward, its inclined surface contacts the inner inclined surface at the top of the rotating part 83 and contracts into the second clamping groove 88. When the second clamping groove 88 is aligned with the through groove 89, the elastic reset action of the second spring pushes the trapezoidal clamping block two 810 out of the second clamping groove 88 and into the through groove 89. At this time, the rotating part 83 can drive the generator housing 84 to rotate. When disassembling the device, the adjusting shaft 2 drives the connecting rod 811 to rise. The connecting rod 811 drives the sliding ring 812 to slide upward on the surface of the tower 1. The sliding ring 812 drives the twisting key 813 to move upward. The twisting key 813 then drives the trapezoidal pressing block 814 to move upward. When the trapezoidal pressing block 814 is aligned with the through groove 89, the elasticity of the second torsion spring drives the twisting key 813 and the trapezoidal pressing block 814 to rotate, so that the trapezoidal pressing block 814 is inserted into the through groove 89 and presses the trapezoidal clamping block two 810, so that the trapezoidal clamping block two 810 contracts into the second clamping groove 88 again. At this time, the clamping shaft 87 can be quickly pulled out of the second groove 85, thus improving the convenience of disassembling the generator housing 84.
