Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a solar photovoltaic bracket. Background Art

[0002] Solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. They are divided into fixed brackets and flexible brackets. The lower part of the photovoltaic flexible bracket is a one-way rigid frame or rack structure, which is connected by pre-tensioned steel strands, and the photovoltaic components are directly fixed on the steel strands. The pre-tensioned steel strands resist deformation through the stiffness generated by tensioning.

[0003] Existing flexible supports often use pre-tensioned cables with nominal diameters of 12.7mm, 15.2mm, 17.8mm and 21.6mm steel strands. The maximum span that can be achieved with a single 21.6mm diameter steel strand is about 40m, but its installation cost is relatively high. In addition, when the span of conventional flexible supports exceeds 40m, the pre-tensioned cables are likely to reach their bearing capacity limit when the wind load is large, and the pre-tensioned cables also have large deflections and poor stability.

[0004] Therefore, how to improve the stability of solar photovoltaic brackets and save installation costs has become a problem that needs to be solved.
