Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, specifically a photovoltaic flexible support mounting base. Background Technology

[0002] The prestressed suspension flexible photovoltaic (PV) support system is a novel type of flexible PV support system. This system applies prestress to the cables to give them stiffness, and through stabilizing cables and four-corner pyramids, forms a stable system, making the system a unified whole to resist lateral loads such as component weight, snow load, and wind load. Simultaneously, the flexible PV support system can effectively control the cable deflection, making it a controllable quantity, resulting in a visually stunning PV power station after construction. Construction employs a sliding installation method, which significantly improves installation efficiency while ensuring the safety of the PV modules, effectively shortening the construction cycle of the PV power station. After the components reach the designated position, specialized connectors are used to fix the components and cables in place.

[0003] In photovoltaic installations, flexible steel cables are installed in parallel between two mounting frames, creating a height difference that forms an inclined mounting surface for installing photovoltaic modules. However, when multiple photovoltaic modules are installed on the steel cables between the two mounting frames, the resulting load is significant, which can easily cause the mounting frames to tilt inward or even collapse. Therefore, a flexible photovoltaic support mounting base is proposed to optimize the above-mentioned existing technology. Utility Model Content

[0025] Please see Figures 1-9In this embodiment of the utility model, a photovoltaic flexible support mounting base includes a tensioning seat 2 disposed on the outside of a mounting frame 1.
