Abstract

The invention relates to a tracking control device of a solar condensation photovoltaic power generation mirror field. The device comprises a pitch tracking control mechanism, an azimuth tracking control mechanism and heliostat transmission mechanisms, wherein the pitch tracking control mechanism comprises a pitch driving rod, a pitch driving wheel and a pitch motor; the azimuth tracking control mechanism comprises an azimuth driving rod, an azimuth driving wheel and an azimuth motor; the pitch motor drives the pitch driving wheel to rotate so as to drive the pitch driving rod to move in a push and pull reciprocating way; the azimuth motor drives the azimuth driving wheel to rotate so as to drive the azimuth driving rod to move in a push and pull reciprocating way; and the pitch driving rod and the azimuth driving rod move in a reciprocating way, and heliostats are driven by all heliostat transmission mechanisms to complete pitch and azimuth operation. In the invention, two motors are adopted to drive an array of heliostats to follow the sun, so that the number of the used motors in a unit light collecting area is reduced, and the mirror field can consist of small-sized heliostats which are light in weight and easy to assemble and modulate and have high anti-wind load capacity, high tracking precision and low energy consumption.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and relates to a tracking control device for a large-scale concentrating solar cell power field, in particular to a tracking control device for a solar concentrating photovoltaic power generation mirror field. Background technique [0002] Solar photovoltaic power generation is divided into concentrated photovoltaic power generation and ordinary photovoltaic power generation. Concentrating photovoltaic power generation uses non-imaging concentrating mirrors to concentrate direct sunlight to concentrating solar cells, which has the advantages of high photoelectric conversion efficiency and less battery materials. Non-imaging concentrators and concentrating solar cells are assembled together to form a concentrating photovoltaic power generation unit. A large number of concentrating photovoltaic power generation units are spliced ​​together to form a whole, called a heliostat. A large number ...
