Abstract

The present invention belongs to the photovoltaic generation research field, and especially provides a dual-axis tracking photovoltaic generation device. The device comprises an upper control industrial control computer and a PLC controller. The upper control industrial control computer is arranged at a control chamber, the PLC controller is arranged in the electrical cabinet of the control chamber, and the dual-axis tracking photovoltaic generation device further comprises a landing leg matrix, a quadruple photovoltaic panel swinging strut, an east-west direction rotation execution mechanism, a north-south direction rotation execution mechanism, an east-west direction rotation transmission mechanism, a north-south direction rotation transmission mechanism and a two-way tilt sensor. The dual-axis tracking photovoltaic generation device realize autorotation of a photovoltaic module at the east-west direction to track sunlight and automatic regulation at the north-south direction according to month transformation, a single controller controls a plurality of photovoltaic tracking subsystems connected in a surrounding area at the same time to reach linkage control and establish an agriculture light complementation photovoltaic generation mode of photovoltaic generation at the upper portion and agricultural cultivation at the lower portion so as to realize one earth used for multiple purposes and promote farmers' income increasing, enterprises' income increasing, government tax increasing and environment gain.

Description

technical field [0001] The invention belongs to the research field related to photovoltaic power generation, in particular to a dual-axis tracking photovoltaic power generation device. Background technique [0002] Solar photovoltaic power generation is a technology that accepts incident sunlight by using an array formed by solar photovoltaic modules, converts light energy into electrical energy through photovoltaic panels, 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 the solar photovoltaic power generation system, a large number of photovoltaic module racks are generally deployed on the open ground (or the surface directly receiving light such as the roof of the building), and the photovoltaic module panels are installed on the racks to receive sunligh...
