Problems solved by technology
Undoubtedly, there are many deficiencies in these two kinds of reflector components in the prior art, wherein the most important deficiencies are: the one is that its own weight is large, which increases the preparation cost of its mounting frame; The ability of sand and hail is very poor, which seriously affects its service life and increases the cost of normal operation; third, because it is exposed to the natural environment without much effective protection measures, the temperature difference between day and night of the reflector component itself Relatively large, especially in the autumn and winter seasons in high latitudes, the mirror surface of the reflector will have serious frosting

Embodiment Construction
[0034] The present invention will be further described below through the description of specific embodiments with reference to the accompanying drawings.
[0035] A typical specific implementation, as attached Figure 1~6 shown.
[0036] A solar concentrating reflector component for tower-type or Fresnel solar thermal power generation, comprising a rear reflector 1 made of toughened ultra-thin ultra-clear glass with a thickness of 1.1-1.6mm, and a mirror surface with a micro-arc plane, And the base 2 arranged on the back of the reflector 1, and the reflector 1 and the base 2 are fixedly connected as one; the base 2 has a corresponding embedded part 3 for fixed connection with its mounting frame , which:
[0037] a. The base 2 is a resin glass fiber fabric hollow sandwich structure FRP product, and the hollow sandwich structure FRP product base 2 is fixedly connected with the reflector 1 by laminating and bonding FRP and the two become one;
[0038] b. The rim 4 of the base 2...

Disclosed in the invention is a tower type or Fresnel solar thermal power generation solar concentrating reflector component, which includes a micro-arc plane rear reflector and a base, and the base is a resin fiberglass fabric hollow clip Core structure FRP parts are the main features. It has the characteristics of reasonable structure, high solar reflectivity, light weight, long service life, and no frost on the mirror surface.
Description
technical field [0001] The invention relates to a tower-type or Fresnel solar thermal power generation solar concentrating mirror component, which belongs to the solar thermal power generation equipment technology. Background technique [0002] The solar concentrating mirror component involved in the present invention has a shape as figure 1 As shown, the reflector mirror surface is a large curvature concave spherical micro-arc plane mirror surface. [0003] The solar concentrating mirror component involved in the present invention is composed of the solar concentrating mirror and a base (or called a back seat) fixedly connected. [0004] Existing solar concentrating reflectors for tower or Fresnel solar thermal power generation are made of toughened glass rear reflectors, assembled with heliostat mounting frames, and multi-point fixing screws for the reflection The different pulling distances adopted by the mirror make the reflector constitute a concave spherical micro-ra...
