Disc-type concentrated reflector of solar power system

Abstract

The invention relates to a disc-type concentrated reflector of a solar power system. The disc-type concentrated reflector comprises a body in the hyperboloid mirror form. A folded edge is formed on the periphery of the body towards a concave of the mirror. Thickness of the folded edge is equal to that of the mirror body. A bent portion of the folded edge and the body has bending radian of 90-135degrees. Length of the folded edge is 1 / 10 of width of the reflector. The disc-type concentrated reflector has the advantages that the traditional molding method of the solar concentrated reflector is replaced, the hyperboloid mirror is formed into the reflector towards the concave with the folded edge arranged on the periphery, and accordingly the problem that due to the reflector itself or environmental factors, deformation stress concentration occurs to the solar concentrating device under the static condition and the dynamic condition, causing the permanent deformation, is solved, and a reference standard is provided for the reflector production industry.

Description

technical field [0001] The invention relates to a reflective mirror used in a solar power generation system, in particular to a reflective mirror for a dish-type concentrating solar power generation system. Background technique [0002] When it comes to solar concentrating technology, generally speaking, the use of concentrating lenses must be introduced. Chinese patent document CN201210197Y discloses the structure of a "solar concentrating mirror": the concentrating mirror includes several fan-shaped and arc-shaped concentrating lenses, and several concentrating lenses are radially arranged in a ring at a certain distance, and each connecting rod connects adjacent The condensing lenses are connected as a whole to form a condensing lens that is in the shape of an arc as a whole. Correspondingly, the Chinese patent document CN10873084A discloses the structure of "a solar energy technology device": it includes a first reflector, a first concentrating lens and a solar panel, a...

AI Technical Summary

Problems solved by technology

[0004] However, for reflective lenses, whether it is the static standby state after the lens is processed and assembled after the solar heat concentrating device or when the heat engine of the solar heat concentrating device is running, after a period of assessment, it will be found that existing or in use The elastic-plastic deformation of the planar-curved concentrating lens

This phenomenon will cause the focusing accuracy of the lens to disperse point by point, and the energy gathering efficiency will gradually decrease until the whole machine of the solar spot tracking system fails.
