Multi-angle steering photovoltaic tracking support

Abstract

The invention provides a multi-angle steering photovoltaic tracking support which comprises stand columns, a first rotating shaft rotationally connected to the tops of a plurality of parallel stand columns and a second rotating shaft perpendicular to the first rotating shaft and rotationally connected to the first rotating shaft, the first rotating shaft and the second rotating shaft are driven by a motor, and a purline is fixed to the second rotating shaft; the lower end of the first rotating shaft is fixedly connected with first swing arms, the free ends of the parallel first swing arms are rotationally connected with a transverse connecting rod, the lower end of the second rotating shaft is fixedly connected with second swing arms, and the free ends of the parallel second swing arms are rotationally connected with a longitudinal connecting rod. The photovoltaic tracking support can rotate in the north-south direction and the east-west direction, and the utilization rate of sunlight in the solar oblique illumination time period is increased; meanwhile, due to the effective connection of the structures between the rows, a plurality of rows of supports rotating in the south-north direction are driven by one motor, each row of supports rotating in the east-west direction is driven by one motor, resources are saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic brackets, in particular to a photovoltaic tracking bracket with multi-angle steering. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. Photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in the solar photovoltaic power generation system. The angle change realizes the adjustable angle to maximize the utilization of solar energy. [0003] The existing automatic angle-adjusting photovoltaic brackets can only adjust the angle in the north-south direction. When the sun is oblique in the morning, morning and afternoon, the solar panel cannot rotate the angle in the east-west direction, and can only absorb the maximum absorption at noon. Solar energy, the overall light utilization rate is not much impro...

AI Technical Summary

Problems solved by technology

[0003] The existing self-adjusting angle photovoltaic support can only adjust the angle in the north-south direction. When the sun is slanting in the morning, morning and afternoon, the solar panel cannot rotate in the east-west direction, and can only absorb it to the greatest extent at noon. Solar energy, the overall light utilization rate is not greatly improved

[0004] Another problem is that the photovoltaic support for automatic angle adjustment is composed of multiple rows and columns. In order to ensure that the solar panels between rows and columns rotate in the same direction at the same time, each row and column need to be driven by a separate motor to rotate. The number of motors required is large, the energy consumption is high, and the cost is correspondingly increased
