[0001] The utility model relates to the field of large-span flexible photovoltaic brackets, and specifically relates to a large-span flexible photovoltaic side-span bracket structure. Background Technique

[0002] With the rapid development of renewable energy, photovoltaic power generation, as a clean and sustainable energy form, has been widely applied. However, traditional photovoltaic brackets face many challenges in large-span installations, such as insufficient structural stability, high installation complexity, and large steel consumption. These problems not only affect the overall performance and service life of the photovoltaic system, but also increase the construction and operation costs.

[0003] At present, most of the existing photovoltaic brackets on the market adopt rigid designs. Although they perform well in small-span applications, in large-span cases, deformation and instability are likely to occur. For example, when installing photovoltaic panels in a sewage treatment plant, due to the large area of the sewage treatment plant, the span of the flexible photovoltaic bracket is also very large, and the wind load effect of strong wind weather on the flexible photovoltaic bracket needs to be considered to ensure its strong stability. In addition, the installation process of the existing brackets often requires special equipment and technology, resulting in a long construction period and affecting the economy of the project. Therefore, there is an urgent need for a new type of bracket structure that can provide better flexibility and stability under large-span conditions.
