Main shaft assembly and photovoltaic tracking support adopting same

Abstract

The invention discloses a main shaft assembly and a photovoltaic tracking support adopting the main shaft assembly. The photovoltaic tracking support is provided with a main shaft and a plurality of stand columns arranged at intervals, the main shaft is horizontally arranged at the upper ends of the stand columns, the main shaft is composed of a plurality of main shaft assemblies, and a main rotation assembly is fixed to the upper end of the middle stand column. Auxiliary rotation assemblies are fixed to the upper ends of the stand columns located on the side portions, the two sides of the main rotation assembly are fixedly connected with the two main shaft assemblies located in the middle correspondingly, the two sides of each auxiliary rotation assembly are fixedly connected with the two main shaft assemblies located on the side portions correspondingly, and the auxiliary rotation assemblies are symmetrically distributed on the two sides of the main rotation assembly; the main rotation assembly and the auxiliary rotation assembly are fixedly connected through a synchronous transmission rod. The main shaft of the photovoltaic tracking support is uniform in bearing strength distribution, safer and more reliable in structural design, light in overall weight and more convenient to produce and install.

Description

technical field [0001] The invention relates to the technical field of solar energy facilities, in particular to a main shaft assembly and a photovoltaic tracking bracket using the main shaft assembly. Background technique [0002] With the continuous progress of society, the solar photovoltaic power generation industry has developed rapidly. In the solar photovoltaic power generation industry, solar photovoltaic support is a key facility to ensure the effective operation of the overall device. At present, solar photovoltaic power generation support is divided into fixed support mode, adjustable support mode and tracking support mode according to the form. The fixed bracket method is an early developed product, which has the characteristics of simple structure, low cost, and stability and reliability. The adjustable bracket method adds the function of adjusting the installation angle of photovoltaic modules with the seasons on the basis of the fixed bracket, and can realiz...
