Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a large-span oblique-stayed stable flexible steel belt structure. Background Art

[0002] In recent years, the research and development of more energy-saving and green new energy power generation industries has been increasingly rapid, and the scale of market applications has continued to expand. Among them, photovoltaic power generation technology, as a power generation technology that has been widely used, plays an increasingly important role in the subsequent upgrading and development of the energy industry. Photovoltaic power generation technology is a technology that uses photovoltaic panels with semiconductor interfaces to directly convert light energy into electrical energy through the photovoltaic effect;

[0003] As the most important component in the photovoltaic power generation system, the photovoltaic panel’s installation method and installation quality have a great impact on the efficiency of photovoltaic power generation. For large-scale photovoltaic systems, photovoltaic panels are generally installed in open outdoor environments, such as hillsides and vast flat land, through photovoltaic brackets. The use of large-span photovoltaic brackets can save steel and install more photovoltaic panels at the same time, which is conducive to improving economic benefits;

[0004] However, during the actual installation process, when encountering severe weather such as strong winds and heavy snow, the stability of the photovoltaic bracket is poor, and the photovoltaic panels themselves have a certain weight. When the span is large, the middle position of the photovoltaic bracket will sink, which will affect the support of the photovoltaic panel. Therefore, a large-span cable-stayed stable flexible steel belt structure is proposed. Utility Model Content
