Condensing lens

Abstract

The invention discloses a condensing lens.The condensing lens comprises a fixed support and a honeycomb core board assembly and a reflector which are sequentially installed on the fixed support in a stacked mode, the honeycomb core board assembly comprises a panel, a honeycomb core board and a backboard, the honeycomb core board is clamped between the panel and the backboard, the reflector is connected with the panel in a sticking mode through a pressure-sensitive adhesive, and the backboard is fixed with the fixed support.According to the condensing lens, the weight of the condensing lens is lighter than that of other types of products, and steel structure loading requirement is low; the surface is smooth and free of corrugation phenomenon, and the optical quality is optimal; the condensing lens can be suitable for batched production and manufacture, the initial capital investment is less, and the benefit can be obtained rapidly; the condensing lens is suitable for rapid and accurate focusing, and the site construction time is shortened.

Description

technical field [0001] The present application belongs to the technical field of photothermal power generation, and in particular relates to a concentrating lens. Background technique [0002] The high cost, dwindling supply and environmental impact of fossil fuels have been driving the development of solar energy and other clean alternatives. [0003] In the field of concentrated solar power generation, traditional concentrating lenses mainly include the following types: [0004] 1. Pure glass is tempered or hot-bent to form a paraboloid, hyperboloid, or spherical surface, and the back of the glass is silver-plated to form a concentrating effect. [0005] Its disadvantages are: tempered glass or hot-bent glass has problems such as high profile error, mass production cannot be realized by silver plating process, uneven thickness of silver layer of lens, and uneven concentration of concentrated energy. [0006] 2. Ultra-thin lenses are pasted on the molded glass fiber reinf...

AI Technical Summary

Problems solved by technology

[0005] Its disadvantages are: tempered glass or hot-bent glass has problems such as high surface error, mass production cannot be realized by silver plating process, uneven thickness of silver layer of lens, and uneven concentration of concentrated energy.

[0007] Its disadvantages are: the FRP backboard has rebound deformation during cooling after hot molding, and at the same time, there is a process of thermal stress release during use, and the backplane cannot guarantee the theoretical equation curve over time.

[0009] Its disadvantages are: the reflective efficiency of the reflective film is difficult to achieve a high index first, and the surface of the film is scratched and degraded under construction or severe sand and dust weather, which leads to a further reduction in reflectivity, which ultimately affects the economic efficiency of the entire system and attenuates quickly

[0011] The disadvantage is that although the back plate made of stretched steel plate has the advantage of mass production, the optical slope error is always out of tolerance due to welding deformation
