Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and particularly to an adjustable photovoltaic bracket and an angle adjustment method thereof. Background Art

[0002] In a photovoltaic power generation system, the photovoltaic bracket is the most important part of the photovoltaic system and plays a role in installing and fixing solar panels. The photovoltaic bracket is a special bracket designed to place, install, and fix solar panels in the photovoltaic power generation system. The photovoltaic bracket is often installed on the roof, curtain wall, or ground of a building.

[0003] However, the adjustment range of the existing photovoltaic brackets remains unchanged during use and cannot be adjusted according to different seasons, reducing the applicability of angle adjustment.

[0004] To solve the above defects, in the prior art, a Chinese patent with the publication number CN218868169U discloses an adjustable photovoltaic bracket, including a base. One side of the base is fixedly connected with a support leg, and the other side of the base is fixedly connected with one end of a thrust bearing. The other end of the thrust bearing is fixedly connected with a box body. A first motor is fixedly connected to the base, and the output shaft of the first motor is fixedly connected to the rotation center of the box body. It can self-adjust its own inclination angle according to the illumination angle to improve the power generation efficiency, can adjust the amplitude of angle adjustment according to different seasons, improves the applicability of angle adjustment. At the same time, in windy weather and extreme weather, the device can retract the photovoltaic panel into the box body, improving the wind resistance of the photovoltaic panel and avoiding damage to the photovoltaic panel by the wind.

[0005] Moreover, in the prior art, a Chinese patent with the publication number CN220067313U discloses an adjustable photovoltaic bracket. Through the provided lifting mechanism and angle-adjustable actuator, the photovoltaic panel can be effectively adjusted. By the cooperation of the forward-rotating ball screw and the reverse-rotating ball screw, the first semi-circular bearing platform is driven to move relatively and towards each other. The lifting column drives the angle adjustment moving component and the angle actuator component to move. At the same time, the second ball screw drives the semi-circular moving platform to move, driving the angle-adjustable bearing column to drive the photovoltaic panel support platform and the photovoltaic panel arranged above to adjust the inclination angle, thereby fixing the inclination angle of the photovoltaic panel, further improving the light collection rate of the photovoltaic panel. The adjustment of the photovoltaic bracket can be realized automatically, with simple operation and convenient use.

[0006] During the use of the above device, the second ball screw drives the angle-adjustable bearing column to rotate, thereby adjusting the angle of the photovoltaic panel. However, in the above device, the second ball screw only drives the angle-adjustable bearing column to rotate. When the photovoltaic panel is adjusted in angle, the photovoltaic panel is too heavy, resulting in unstable inclination, which causes damage to the bracket. Therefore, in actual use, the bracket will be damaged when the photovoltaic panel is too heavy and causes the bracket to tilt. Summary of the Invention
