Description

Technical Field

[0001] The utility model specifically relates to the technical field of flexible photovoltaic brackets, in particular to a single-layer cable bracket with high wind resistance and high stability and capable of adapting to complex terrains. Background Art

[0002] Among the many photovoltaic application scenarios, mountainous areas are generally recognized as the most difficult scenarios for photovoltaic power station design and construction due to their complex gullies, complicated and changeable terrain, geology, geomorphology and hydrological conditions. In addition, with the tightening of land use policies, how to improve land use efficiency and increase internal rate of return has become the core demand of photovoltaic owners.

[0003] The flexible bracket uses a method of tensioning prestressed steel strands between two fixed points. The two fixed points use a rigid foundation to provide reaction force, which can achieve a large spacing of tens of meters. This design can avoid unfavorable factors such as undulating mountains and high vegetation. It only needs to set the foundation points at the appropriate location and tension the prestressed steel strands. Compared with traditional rigid photovoltaic brackets, flexible photovoltaic brackets have the characteristics of light weight, large span, simple structure and low cost. They have better adaptability to terrain and can effectively utilize unfavorable terrain such as mountains and fish ponds.

[0004] However, there are also some problems with flexible brackets. The single-layer cable structure system is prone to shaking up and down under wind loads, the central column tilting to one side during tensioning, and hidden cracks in photovoltaic modules. How to effectively reduce the deformation of module cables under wind loads, improve the overall stability of the bracket structure, and reduce the risk of hidden cracks in modules is one of the key issues in this field.
