Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a flexible photovoltaic support for supporting photovoltaic panels, applicable to photovoltaic power plants, distributed photovoltaic systems, and other scenarios. Background Technology

[0002] With the continued growth of global demand for clean energy, photovoltaic (PV) power generation, as an important way to utilize renewable energy, is expanding its application scale. PV support structures, as key structures supporting PV panels, directly affect the stability, lifespan, and economic benefits of PV power generation systems. Currently, most traditional PV support structures widely used in the market are rigid structures, such as fixed concrete supports and steel structures. These types of supports have significant limitations: First, they require high-quality installation sites, necessitating flat ground. In complex terrain areas such as mountains, slopes, and tidal flats, not only are initial site preparation costs high, but construction is also difficult, hindering widespread application. Second, rigid supports consume large amounts of materials, such as steel or concrete, leading to high costs and requiring more manpower and resources for transportation and installation. Third, rigid structures lack flexibility; when faced with dynamic loads such as strong winds and snow accumulation, stress concentration issues become prominent, making the structure susceptible to damage and affecting the long-term stability of the PV system.

[0003] Although some improved photovoltaic (PV) support structures have emerged in existing technologies, such as tracking supports that adapt to sunlight by adjusting their angle, or new supports that utilize lightweight materials, core issues such as adaptability to complex terrain, optimization of rigid-flexible mechanics, and overall cost control have not been effectively resolved. Therefore, developing a PV support structure that combines terrain adaptability, structural stability, and economic practicality has become a pressing technical challenge in the PV power generation field. The flexible PV support structure of this invention is an innovative solution proposed based on these industry pain points. Summary of the Invention

Cable tensioning mechanisms are respectively provided on the first main cable 1-1, the first auxiliary cable 1-2, the second main cable 2-1, and the second auxiliary cable 2-2.

[0024] In this embodiment, the first sub-frame includes a first support rod 4-2 and a second support rod 4-3.
