Abstract

The invention provides a photovoltaic biaxial linkage tracking system, and relates to a photovoltaic module subsystem biaxial tracking system. The photovoltaic biaxial linkage tracking system is characterized by comprising a plurality of independent photovoltaic tracking assembly subsystems which are arranged in longitudinal lines in tandem along a first direction and connected through universal couplers. Each photovoltaic tracking assembly subsystem comprises a fixed beam truss structure (220), wherein a plurality of photovoltaic panel installation positions are arranged on the upper front surface of the fixed beam truss structure (220), fixed ends for hauling cables (308) are installed under two sides of the back surface, and the plurality of photovoltaic panel installation positions are used for installing photovoltaic panels; and a first direction rotating shaft of one photovoltaic tracking assembly subsystem in the middle of the subsystems which are arranged in longitudinal lines in tandem is connected to a first direction rotation control mechanism through a universal coupler, the first direction rotation control mechanism controls the rotation of the first direction rotating shaft, and a second direction rotating shaft control rod of the photovoltaic tracking assembly subsystem in the middle of the subsystems which are arranged in longitudinal lines in tandem is connected to a second direction rotation control mechanism.

Description

technical field [0001] This application generally relates to the field of photovoltaic power generation, and in particular to a dual-axis linkage tracking control system for photovoltaic power generation devices. Background technique [0002] Solar photovoltaic power generation is a technology that accepts incident sunlight by using an array formed by a subsystem of solar photovoltaic modules, converts light energy into electrical energy through photovoltaic conversion, and collects the generated electrical energy for use. This technology has the advantages of no pollution, low cost, and sustainable power generation, and it is increasingly used in tropical or desert areas with strong sunlight all over the world. [0003] At present, in solar photovoltaic power generation systems, a large number of photovoltaic module subsystem racks are generally deployed on the open ground (or directly illuminated surfaces such as building roofs), and photovoltaic panels are installed on th...
