Description

Technical Field

[0001] The utility model specifically relates to the technical field of flexible photovoltaic brackets, in particular to a novel wind-resistant flexible photovoltaic bracket. Background Art

[0002] At present, photovoltaic new energy projects are continuously promoted and gradually combined with fisheries and agriculture to form a new model of complementary development of multiple industries. Flexible photovoltaic brackets are a structural system that installs photovoltaic modules on flexible cables and applies prestress by tensioning the cables to provide bearing capacity. According to the number of cables, the common flexible photovoltaic brackets currently include single-layer double-cable systems and double-layer three-cable systems. Compared with traditional rigid photovoltaic brackets, flexible photovoltaic brackets have the characteristics of light weight, large span, simple structure and low cost, and have good adaptability to terrain, which expands the application scope of photovoltaic power generation.

[0003] However, there are also some problems with the flexible photovoltaic support structure. The single-layer double-cable system structure has limitations in terms of span, and often has large deformations, which can easily cause hidden cracks in photovoltaic modules. The double-layer three-cable system improves the support's bearing capacity by adding stabilizing cables, but it also has disadvantages such as poor structural stability and weak wind resistance. Especially in areas with large wind loads, the wind suction effect of the structure is significant, the bearing capacity of the cable is greatly weakened, and the support will produce obvious upward displacement deformation, which has a greater adverse effect on the safety of the photovoltaic support. Therefore, how to strengthen the ability of flexible photovoltaic supports to resist wind suction and avoid hidden cracks or flipping of photovoltaic modules is one of the key issues in this field.
