Description

Technical Field

[0001] This invention relates to the field of photovoltaic support equipment, and in particular to a wind-resistant stepped photovoltaic support. Background Technology

[0002] A photovoltaic (PV) support structure is a support structure designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system. Its structure is formed by connecting the support structure with steel cables, and then fixing the solar panels to the steel cables, arranging them in a large-scale array.

[0003] Application No. 202220228248.3 discloses a steel cable photovoltaic support structure, which features an upper stabilizing steel cable structure, stabilizing rods between the upper struts and the multi-array array, and a large gap between the front and rear rows of solar panels. This design helps to ventilate and effectively reduce wind pressure. However, its drawback is that the inclined beam structure is in a straight line. This inclined beam structure inevitably results in the front and rear rows of solar panels being installed on an angled line. With this design, when the wind speed is high, most of the wind blowing through the first row of solar panels is absorbed by the rear row of solar panels, resulting in excessive wind pressure on the rear solar panels and increasing the safety hazard of the entire support system. Moreover, the stabilizing rods connecting the front and rear arrays use giant steel pipes, and the intermediate piles use a combination of I-beams and struts, which increases manufacturing costs.
