Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and more specifically, to a photovoltaic tracking support. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductors to convert solar energy into electrical energy. Traditional photovoltaic power generation equipment includes photovoltaic brackets and photovoltaic panels installed on the brackets. In the above-mentioned photovoltaic power generation equipment, the position between the photovoltaic panels and the photovoltaic brackets remains unchanged, while the angle at which sunlight hits the photovoltaic panels is constantly changing. Therefore, the photovoltaic panels in the above-mentioned photovoltaic power generation equipment have low absorption efficiency of sunlight, resulting in poor power generation performance.

[0003] Currently, in existing technologies, if photovoltaic brackets need to be adjusted, most of them are installed on adjustment structures, and only rotation in one direction is possible. This makes it impossible to adjust to any angle according to site requirements, which greatly reduces the flexibility of adjustment and the light absorption efficiency. Summary of the Invention

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] 1. A flipping component is installed on the support column. The flipping component is equipped with a bracket component, and the bracket component is equipped with a lever component. The solar photovoltaic panel is installed on the lever component. The flipping component can be used to flip the panel in different directions, so that the solar photovoltaic panel can adjust the flipping direction according to the light source and improve the solar energy collection efficiency.

[0017] 2. The support frame can drive the solar photovoltaic panel to slide along the arc-shaped guide rail of the circular ring, so that the solar photovoltaic panel can move on a horizontal plane. When the support frame is combined with the flipping component, it can not only flip in different directions such as front and back or left and right, but also move on a horizontal plane, increasing the energy storage capacity of the light source.

[0018] 3. The lever assembly supports the solar photovoltaic panel. The limiting wheel is always located in the inverted V-groove formed between the two wing plates. This ensures that no matter how the cylinder rotates, the tilt angle of the lower wing plates on both sides is limited by the limiting wheel, preventing the solar photovoltaic panel from collapsing due to strong winds and excessive rotation angle. The gravity blocks on both sides of the rotating arm form a vertical downward force under their own weight, reducing the rotation angle of the cylinder and improving the balance of the horizontal strip.

[0052] Detailed usage and function of this embodiment:

[0053] When the motor 8 is started, the motor 8 drives the fixed column 9 to rotate. After the fixed column 9 rotates, the arc frame 10 connected to one side will flip left and right together. The arc frame 10 drives the column 11. After the column 11 rotates, the shaft 12 inserted on one side of the column 11 will flip left and right together. The shaft 12 drives the circular ring 13 to flip left and right.

[0054] When the motor 15 is started, it drives the gear 16 to rotate. The gear 16 drives the meshing gear 17 to rotate. After the gear 17 rotates, it drives the shaft 12 that is inserted in the middle, causing the shaft 12 to drive the circular ring 13 to flip back and forth.

[0055] When the second motor 19 is started, it drives the first gear 20 to rotate. The first gear 20 rolls on the tooth groove of the side gear 21. The first guide slider 26 and the second guide slider 28 slide in the corresponding arc-shaped guide rail 14. The first guide slider 26 and the second guide slider 28 drive the fixed block 22 and the disc 18 to slide along the periphery of the circular ring 13. The arc-shaped frame 25 drives the solar photovoltaic panel 7 to move.

[0056] The mounting bracket 6 presses down on the horizontal strip 32. Under the elastic action of the return spring 35, the limiting wheel 37 is always pressed against the inverted V groove of the two wing plates 39. Under the action of the gravity of the gravity blocks 45 on both sides, a downward gravity is generated, which reduces the amplitude of the angular rotation of the rotating arm 42 and improves the balance of the horizontal strip 32.

[0057] Through the specific embodiments described above, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
