Abstract

The invention relates to a composite process of a reflecting lens assembly of a disc-type solar spotlight tracking system. The composite process is characterized by comprising the following steps: integrally combining a hyperboloidal fan-shaped base plate with reinforcing ribs and a hyperboloidal fan-shaped panel in a mode of welding so as to form a hyperboloidal fan-shaped metal back plate; carrying out electrophoretic paint dip-coating for rust prevention on the whole of the hyperboloidal fan-shaped metal back plate, and subsequently spraying automobile finish to one plane at which the reinforcing ribs are located on the hyperboloidal fan-shaped metal back plate; shearing PA and EN films; machining thin glass into a flat tapered spotlight reflecting lens; putting the sheared PA and EN films between the hyperboloidal fan-shaped metal back plate and the flat tapered spotlight reflecting lens, and positioning; putting the positioned combined piece into a vacuum bag and entering a vacuum gel clamping furnace; and vacuuming in advance, heating, rising the temperature, cooling and taking out of the furnace, thereby accomplishing the composite molding. After being composited, the reflecting lens assembly does not crack or drop off, is good in high or low temperature resistance, strong in impact resistance and can pollute the environment; and the contact rate of the composite plane can be more than 98%.

Description

technical field [0001] The invention relates to a reflector lens assembly of a dish-type solar concentration tracking system, which is a core component in the dish-type solar concentration tracking system and belongs to the field of photothermal technology. Background technique [0002] In the existing technology, the reflective lens assembly in the dish-type solar concentrating tracking system is made of fan-shaped 5mm single-layer glass, which is tempered by hot-bending hyperboloids. After forming, it is chemically silver-plated, and then coated with solar mirror paint on the silver layer. With a height of 1000mm and a width ranging from 900 to 300mm, it consists of 77 reflective lens components of 4 specifications to form a disc-shaped member with a diameter of 9 meters. Each lens is fixed on the disc-shaped bracket by 4 screws for focusing. [0003] This fan-shaped hyperboloid concentrating reflective lens assembly has the following disadvantages: [0004] 1: Hot bendin...
