[0002] As global greenhouse gas emissions intensify and climate change becomes a serious problem, the international community's demand and pressure to reduce carbon emissions are increasing year by year. Traditional energy sources are facing price fluctuations, resource depletion, environmental pollution and other problems. Energy transformation is imperative. As a clean energy source, solar photovoltaic power generation is widely used and is highly respected worldwide, and has received strong support and development. Photovoltaic brackets are an important part of solar photovoltaic power generation systems. They carry photovoltaic panel components and are fixed to the ground. In recent years, solar flexible photovoltaic bracket systems have received more and more attention due to their unique technical characteristics, and have broad prospects and competitiveness in the industry. Due to the structural characteristics of the flexible system, it is extremely important to determine whether its wind resistance meets the requirements.

[0003] The existing flexible support system mainly adopts a single-layer double-cable structure and a double-layer three-cable structure. The disadvantage of the single-layer double-cable structure is that the span is small and it is suitable for some special terrains but the economic benefits are not particularly high; the disadvantage of the double-layer three-cable structure is that it has poor wind resistance.

[0004] In view of this, the inventor hopes to provide a wind-resistant flexible photovoltaic bracket based on a double-layer multi-cable structure, which can meet the span requirements, have a stable structure, be easy to construct, and have sufficient wind resistance. Utility Model Content
