Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a flexible photovoltaic bracket installation structure. Background Art

[0002] Flexible photovoltaic brackets can effectively solve the adaptability and economic problems of photovoltaic brackets in certain mountainous scenarios, so they are widely used in mountain photovoltaic power stations. Flexible photovoltaic brackets are rapidly expanding their application scope in the field of photovoltaic power generation due to their characteristics of saving land resources, low cost, large span, high clearance, less consumables, strong pre-installation, and greatly shortening the overall construction period, becoming one of the key technologies to promote the further development of the photovoltaic industry and energy transformation.

[0003] A single set of flexible photovoltaic brackets usually includes a base, steel cables, an anchoring system, photovoltaic modules and connecting stabilizing components. The photovoltaic modules are fixed on the steel cables stretched between the two bases to reduce the materials required for the supporting structure of the photovoltaic modules. The axial tension of the stretched steel cables is used to bear the load on the photovoltaic modules. The anchoring system and the connecting stabilizing components stabilize and connect the flexible photovoltaic brackets.

[0004] The existing flexible photovoltaic brackets usually include at least two groups of flexible photovoltaic brackets arranged in a longitudinal arrangement, and a connecting rod is arranged between two adjacent groups of flexible photovoltaic brackets, and the two ends of the connecting rod are respectively connected to the bases of the two adjacent groups of flexible photovoltaic brackets. Due to the undulating mountain terrain, the two adjacent groups of flexible photovoltaic brackets are not completely parallel, which makes the required connecting rods not of uniform standard length. The existing construction often adopts on-site cutting and welding methods to adjust the length of the connecting rod according to the actual situation on site. However, the heavy generators, cutting machines and welding machines are transported in the mountains, which undoubtedly increases the labor intensity and construction difficulty of the workers.
