Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic technology, and more specifically, to a flexible photovoltaic wind-resistant frame and a flexible photovoltaic support. Background Technology

[0002] Flexible photovoltaic (PV) support structures typically support PV modules directly via two main cables. End and middle supports constrain the main cables and provide prestressing conditions. To support the PV modules, the main cables of the flexible PV support structure are usually arranged in parallel, forming a planar structure. Planar structures generally have poor stiffness and stability. The main function of the wind-resistant frame is to rigidly connect the main cables to the stabilizing cables, forming a spatial structure with better overall integrity and stability. This prevents structural damage and microcracks in the modules when the flexible PV support structure is subjected to wind loads, snow loads, and gravity loads. Current wind-resistant frames are planar trusses, which have poor stability and insufficient load-bearing capacity.

[0003] Therefore, how to improve the structural stability of wind-resistant frames to reduce the risk of microcracks in flexible photovoltaic supports has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
