Photovoltaic bracket suspension support structure
ActiveCN224289696UPerfect for simplicity needsreduce transport volumePhotovoltaic supportsPhotovoltaic energy generationRight triangleAgricultural engineering
This utility model discloses a photovoltaic bracket suspension support structure, mainly comprising triangular support stabilizing units. Each triangular support stabilizing unit consists of two equally sized right-angled triangular supports symmetrically arranged on the left and right sides of a column. The right-angled triangular supports are composed of a column, a crossbeam, and diagonal braces, with the column and crossbeam serving as the right-angled sides and the diagonal braces as the hypotenuses. The two right-angled triangular supports share a single column. This utility model offers advantages such as economy and safety, high construction efficiency, and rapid component installation. It effectively solves problems such as difficulty in installing photovoltaic modules in fish-solar hybrid projects, agricultural-solar hybrid projects, and projects with excessively high ground clearance, which often result in low efficiency, long construction periods, and uneconomical costs.
