Heliostat with glass micro-arc curved surface mirror forming process structure

Abstract

The invention discloses a heliostat through glass micro-arc mirror shaping technique in the solar utilizing technical domain, which is composed of curved mirror composite adjusting device and a group of single-chip glass micro-arc curved mirror shaping adjusting device, wherein the glass mirror rack of the single-chip glass micro-arc curved mirror shaping adjusting device is connected with the glass mirror through three groups of adjustable connecting devices at two ends or in the middle; two ends of each single-chip glass micro-arc curved mirror shaping adjusting device are fixed on the main frame of the curved mirror composite adjusting device through at least two groups of locking fixing piece, which are arranged adjacently; the incidence adjusting device is loaded near two groups of locking fixing piece adjacent to the main frame.

Description

technical field [0001] The invention relates to a heliostat in a solar power generation system, in particular to a heliostat composed of a glass micro-arc curved mirror, which belongs to the technical field of solar energy utilization. Background technique [0002] Solar thermal power generation technology converts solar energy into thermal energy and then into electrical energy through concentrated heat collection, which is one of the most promising ways of utilizing solar energy. [0003] At present, concentrating heat collection technology can be divided into two types: line focusing and point focusing according to the way of concentrating light. In the field of solar thermal power generation technology, three types of solar thermal power generation have been formed: trough-type line-focusing thermal power generation, dish-type thermal power generation and tower-type thermal power generation. system. Among them, the tower solar thermal power generation system has the adv...

AI Technical Summary

Problems solved by technology

This process has the following shortcomings: (1) The cost of forming the curved surface of the heliostat glass is high; this increases the initial investment cost of the tower solar power plant and restricts the large-scale development of tower thermal power generation

(2) The requirements for the production of glass hot bending molds are high; for large-scale tower solar thermal power stations, due to the large focal length of the heliostat and the small curvature of the heliostat, the glass hot bending mold must be very precise. For mechanical manufacturing higher level requirements

(3) Curved glass coating process is difficult to realize; special coating equipment is very expensive, and the size of curved glass is limited

Obviously, the existing foreign heliostat glass mirror molding process structure is not suitable for the current national conditions of our country
