Solar glass reinforced plastic back plate condensing lens assembly and processing method thereof

Abstract

The invention discloses a solar glass reinforced plastic back plate condensing lens assembly and a processing method of the condensing lens assembly. The condensing lens assembly comprises a lens set, a glass reinforced plastic back plate and support assemblies, wherein the lens set consists of a plurality of ultrathin plain glass lenses; the glass reinforced plastic back plate is made of SMC (Sheet Molding Compound) molded glass reinforced plastic; and the support assemblies comprise support rods, upper cover plates and lower cover plates. The processing method comprises the steps of dividing to form the lenses with equal length according to the dimension of the glass reinforced plastic back plate, combining the lenses into the fan-shaped lens set according to a certain layout, silvering the back surface of glass by a chemical glass silvering method or a nano silvering method, coating ultraviolet protective paint or protective paint with an adhesive force greater than Grade 1 on the surface of a silver layer, fabricating the glass reinforced plastic back plate, gluing the lens set and the glass reinforced plastic back plate, and sealing the edge of the lens set with a weather-proof adhesive or a structural adhesive. The condensing lens assembly is high in reflectivity and good in condensation performance, and has a high adaptive capacity to an environment.

Description

technical field [0001] The invention relates to a solar fiberglass back plate concentrating lens assembly and a processing method thereof. Background technique [0002] The solar concentrating system is a device used to absorb and collect solar energy in the solar thermal utilization system. It is the key to affecting the efficiency of solar energy utilization. Its core component is the concentrating lens assembly. The existing concentrating lens assembly has the following problems: Pure glass is tempered or hot-bent, and the formed paraboloid, hyperboloid or spherical surface has a high error, and mass production cannot be realized when the lens is silvered, and the thickness of the silver layer is uneven, which affects the light-gathering effect; Several small pieces of plastic lenses are fixed to the plastic back plate to form a parabolic structure. The plastic lens and the plastic back plate have poor aging resistance and low impact resistance, which cannot meet the need...

[0002] The solar concentrating system is a device used to absorb and collect solar energy in the solar thermal utilization system. It is the key to affecting the efficiency of solar energy utilization. Its core component is the concentrating lens assembly. The existing concentrating lens assembly has the following problems: Pure glass is tempered or hot-bent, and the formed paraboloid, hyperboloid or spherical surface has a high error, and mass production cannot be realized when the lens is silvered, and the thickness of the silver layer is uneven, which affects the light-gathering effect; Several small pieces of plastic lenses are fixed to the plastic back plate to form a parabolic structure. The plastic lens and the plastic back plate have poor aging resistance and low impact resistance, which cannot meet the needs of long-term outdoor operation; To obtain the light-gathering effect, the reflection efficiency is difficult to achieve a high index, and the surface of the reflective film is easily scratched, easy to attenuate and degrade; Poor adaptability and weak anti-aging performance, resulting in low solar energy utilization efficiency
