Description

Technical Field

[0001] The present invention relates to the field of solar photovoltaic and supporting devices thereof, and in particular to a cable-driven wind-resistant flexible photovoltaic support and a use method thereof. Background Art

[0002] As the global demand for energy continues to rise and the greenhouse effect becomes more pronounced, a global wave of pursuit of green energy transformation has been set off. Photovoltaic power generation, with its clean and renewable characteristics, is increasingly becoming an important part of energy supply. As an important part of clean energy, photovoltaic power generation is facing new development opportunities and challenges. Flat land is an ideal site for photovoltaic power generation, and its installation area has gradually become saturated. In order to further expand the application scope of photovoltaic power generation and improve the utilization rate of clean energy, complex terrains such as mountains have become new development hotspots. However, correspondingly, the terrains such as mountains are complex and the terrain winds are obvious. When facing complex and changeable environmental conditions, especially in geographical areas with strong winds, the design of traditional photovoltaic brackets faces the dual challenges of stability and adaptability.

[0003] Traditional photovoltaic brackets are rigid structures with poor adaptability to complex terrain. At the same time, due to the limitations of structural characteristics, rigid photovoltaic brackets are difficult to effectively disperse wind force in windy environments, which can easily lead to stress concentration and structural fatigue, and then cause structural damage, affecting the overall stability and service life of the photovoltaic system. Existing flexible brackets usually use steel cables or other prestressed structures. Although they improve the adaptability to terrain and have a certain degree of flexibility, they can alleviate the impact of wind loads on the structure to a certain extent. However, due to their purely flexible structure and insufficient rigidity, their swing under continuous wind force may cause collisions between photovoltaic panels, causing damage to photovoltaic panels and causing major accidents such as fires.

[0004] In addition, the existing flexible brackets use a fixed installation method for photovoltaic panels, which limits the flexible response of photovoltaic panels to lighting conditions and cannot be adaptively adjusted according to changes in the position of the sun or changes in external natural conditions, thereby affecting the power generation efficiency and service life.

[0005] Therefore, a cable-driven wind-resistant flexible photovoltaic bracket and a method of use are needed to solve the problems existing in the prior art. Summary of the invention

The telescopic rod (406) can be extended along the arrangement direction of the steel cable (2). Both ends of the telescopic rod (406) are equipped with support rods (412) that are supported upwards. The support rods (412) are supported upwards and intersect with the installation box (411). A photovoltaic panel (5) is installed above the installation box (411).

7. A cable-driven wind-resistant flexible photovoltaic support as claimed in claim 6, characterized in that: The front end of the front connection point (401) is provided with a protruding block (407), and the rear end of the rear connection point (403) is provided with a concave block (408), and the protruding block (407) can extend into the concave block (408).

8. The method for using a cable-driven wind-resistant flexible photovoltaic support according to claim 7, characterized in that: The steps include: Step a, when bad weather conditions occur, the photovoltaic panel (5) adjusts the photovoltaic panel angle, the drive motor (103) starts, and drives the cable winch (105) to tighten the drive rope (3), the drive rope (3) shortens under the movement of the cable winch (105), pulls the rope rings (404) closer to each other, drives the middle connection point (402) to move downward, the spring inner rod (414) gradually extends, compresses the spring (415), and the second fixing member (410) slides backward along the direction of the steel cable (2), and the concave block (408) located in the front approaches the convex block (407) located in the rear, until the frame composed of the connecting rods (418) changes from a parallelogram to a rectangle, the convex block (407) is embedded in the concave block (408), and the entire structure becomes rigid; Step b, when the bad weather ends, the photovoltaic panel (5) readjusts the photovoltaic panel angle, the drive motor (103) starts in the reverse direction, drives the winch (105) to release the drive rope (3), the drive rope (3) becomes longer under the movement of the winch (105), the compressed spring (415) rebounds, drives the spring inner rod (414) to gradually retract, so that the rope rings (404) move away from each other, drives the middle connection point (402) to move upward, and the second fixing member (410) slides forward along the direction of the steel cable (2), and the concave block (408) at the front gradually moves away from the convex block (407) at the rear, until the frame composed of the connecting rods (418) changes from a rectangle to a parallelogram in the initial state, and the structure as a whole becomes flexible.
