Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a large-span flexible photovoltaic support. Background Technology
[0002] Due to geographical and environmental limitations, more and more photovoltaic (PV) systems are increasingly opting for flexible PV supports in recent years. However, existing flexible PV supports have shortcomings in terms of structural system and force transmission path. The main cable and backstay are anchored to the tower beams, resulting in significant localized stress concentration and a substantial increase in the number of anchor points, leading to higher costs. Furthermore, the tower columns are compression-bending structures, causing significant stability issues and severely restricting the development of large-span flexible PV supports. Therefore, it is essential to find a flexible PV support that is economical, efficient, has a large span capacity, and is not limited by geographical constraints. However, existing large-span flexible PV supports still suffer from low overall strength, an inability to flexibly handle minor deformations, and a tendency for steel cables to loosen.
[0003] Therefore, it is essential to invent a large-span flexible photovoltaic support system. Utility Model Content

The connecting base is fixedly installed at the bottom of the support frame, and the support frame is fixedly installed on the ground surface via the connecting base. The connecting seat is fixedly installed at the top of the support frame. The tensioning structure is rotatably installed inside the connecting seat. An intermediate support leg is installed on the outer side of the intermediate support frame, and the intermediate support leg is fixedly installed on the ground surface between two sets of support frames.
[0005] The tensioning structure includes a rotating seat, a support arm, an intermediate traction seat, an intermediate traction block, and a flexible bracket.

The top force-applying seat is fixedly installed on the top of the support arm, and the top force-applying block is rotatably installed inside the top force-applying seat. The force-applying tension cable is fixedly installed on the top force-applying block.

The support base is fixedly installed on the top of the support skeleton, and the pressure block is fixedly installed above the support base. A flexible bracket is sandwiched between the support base and the pressure block, and the extension bracket is fixedly installed at both ends of the support skeleton. Intermediate support legs are slidably installed at both ends of the support skeleton and inside the extension bracket, and are fixed with bolts. The stabilizing steel cable is fixedly installed on the front and rear sides of the support skeleton and fixed to the ground.
[0008] The tensioning structure forms a force-saving lever structure, with the center of the rotating seat as the center. The support arm is pulled outward and rotated by the tension cable, so that the middle tension block can move outward, thereby tightening the flexible support. The tensioning flexible support is made of steel metal cable, and the surface of the tensioning flexible support can be used to install photovoltaic brackets. The tension cable is made of steel metal cable, and after the tension cable is applied, one end of it is fixed to the ground.
[0009] Several intermediate support frames are used, and all intermediate support frames are on the same plane and supported on the ground by adjusting the intermediate support legs; the intermediate support frames can be connected and fixed to the flexible bracket through the support base and pressure block, and are kept stable by the tension of the stabilizing steel cable.

[0011] 1. The tensioning structure of this utility model, through the fulcrum of the rotating seat, the lever amplification effect of the support arm, and the input force of the tensioning cable, drives the displacement of the intermediate traction block to dynamically tighten the flexible support.

Its labor-saving design and adjustability ensure the flatness and long-term reliability of the photovoltaic panel installation surface.
[0012] 2.
