Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a rotatable steel cable clamp. Background Technology

[0002] In recent years, China's photovoltaic industry has developed rapidly, but available land resources are becoming increasingly scarce. Traditional fixed supports can no longer meet market demands. The method of installing photovoltaic modules using flexible suspension supports is gaining increasing market acceptance, especially in mountainous projects. Flexible supports can ignore the impact of terrain, allowing for the construction of photovoltaic power plants and improving the utilization rate of mountainous areas. However, mountainous terrain is complex and undulating, making it difficult to maintain a uniform height for the steel cables of the flexible supports. This results in numerous bends in the cables, affecting their load-bearing capacity. Therefore, solving the problem of ensuring the load-bearing capacity of steel cables in complex terrain with bends is a pressing issue that needs to be addressed.

[0003] The closest prior art to this utility model is Chinese Utility Model Patent No. CN222363347U, entitled "A Steel Cable Clamp for Photovoltaic Panel Profiles." This utility model relates to the field of steel cable clamps, and particularly to a steel cable clamp for photovoltaic panel profiles. The photovoltaic panel profile steel cable clamp includes: a U-bolt; the U-bolt includes two threaded rods and a U-shaped portion, with both ends of the U-shaped portion connected to the threaded rods; wherein a stop block is provided below the U-shaped portion, and a locking element for fixing the steel cable is provided below the stop block; the locking element includes an upper locking buckle. The photovoltaic panel profile steel cable clamp provided by this utility model, through the setting of the locking element and the design of the upper and lower locking buckles within the locking element, can effectively lock the steel cable, preventing it from loosening or falling off during operation. Simultaneously, the cooperative design of the positioning screw and anti-slip bolt can increase the stability and anti-slip properties of the fixation, ensuring that the steel cable can be firmly fixed in place under various working conditions, improving work efficiency and safety, and facilitating installation and disassembly.

[0004] By reading the specification of this utility model patent, it can be seen that it cannot solve the technical problem of connecting steel cables with bends in complex terrain and ensuring the stress performance of the steel cables.

[0005] This utility model is proposed to address the relative shortcomings of existing technologies. Utility Model Content
