Description

Technical Field

[0002] A photovoltaic flexible support structure is a support structure used to mount solar panels, designed to provide stable support and adaptability to various installation environments. Compared to traditional rigid supports, flexible photovoltaic supports offer greater adaptability and flexibility, meeting the needs of diverse sites. Specifically, the flexible support solution replaces the traditional rigid support system with steel strands. Its unique feature is that the strands are pre-tensioned using a pre-wire method. After the panels are installed, the strands are allowed to deform slightly under varying load conditions. This allows for large spans of 10 to 30 meters, meeting the needs of diverse terrains.

[0003] During the actual installation of photovoltaic flexible brackets, for mountainous terrain with large slopes and steep ground, in addition to the two end brackets at the upper and lower ends, several middle brackets should be set between the end brackets according to the terrain conditions to further improve the overall stability of the photovoltaic flexible bracket. However, most of the middle brackets in the existing technology are simple T-shaped I-beam structures, and their upper supports are horizontal planes, which cannot be adaptively adjusted according to the two main steel strands and the stabilizing steel strands, causing the steel strands at some supporting positions to be severely deformed and the pre-tension direction to be offset, affecting the overall stability of the photovoltaic flexible bracket installation. At the same time, since the top of the middle bracket is in rigid contact with the steel strand, the service life of the steel strand will be reduced after long-term use. Utility Model Content
