Problems solved by technology

[0005] The existing disc-shaped photothermal power generation backplane is generally composed of a steel plate and a reflective mirror attached to the steel plate. It has a strong structural strength and has a relatively outstanding effect in terms of wind resistance and deformation, but the overall weight is heavy and the transportation is not large. Convenient, and the temperature and weather resistance of the steel plate is poor, which is not conducive to long-term use
According to the solar concentrating disc published in the second issue of 2012 "Solar Concentrating Disc Technology Development Status", the concentrating disc emitter mirror group composed of 82 concentrating mirrors is used, and the total reflection area is 87.82.m 2 , the weight of the entire concentrator reaches 7257kg, which is not conducive to mass production, and the on-site concentrator adjustment is time-consuming and laborious

Embodiment 1

[0029] Such as figure 1 with 2 As shown, a photothermal power generation composite material backplane includes a backplane 1 and a reflective mirror laid on one side of the backplane. The other side of the backplane 1 is provided with a plurality of ribs 2 and a plurality of connecting discs. 3. The ribs 2 extend from the edge of the connecting disc 3 to the edge of the back plate 1 . A plurality of nuts 4 are arranged on the connecting disk 3 . The backplane 1 and the connection disc 3 are made of epoxy resin. Further, a reinforcing layer is arranged inside the backboard. Further, the reinforcement layer includes chopped strand mat, square cloth, triaxial cloth, and PVC sandwich foam laid sequentially from the outside to the inside. The setting of the reinforcement layer can enhance the strength of the composite material backplane, and protect the backplane structure from being damaged by particles such as external sand and gravel. Further preferably, the reinforcing ri...

Abstract

The invention relates to a photothermal power generation composite material backplane and a preparation method thereof. The composite material backplane includes a backplane and a reflective mirror surface laid on the backplane, and the backplane is provided with a reinforcement integrally formed with it. Ribs and a plurality of connecting discs, the connecting discs are tightly connected with the reinforcing ribs, and the back plate and the connecting discs are both made of epoxy resin. Firstly, the connecting discs are prepared in the mold, and then on the back In the plate mold, the reinforcement layer auxiliary materials, reinforcement ribs, connecting discs and vacuum auxiliary materials are laid according to the requirements, epoxy resin is vacuum poured, and after cooling and forming, a back plate integrally formed with the reinforcing ribs and connecting discs is obtained, and then in the The reflective glass is glued on the back plate to obtain a composite material back plate. Compared with the prior art, the composite material backboard prepared by the invention has uniform structure, high strength, low cost, long service life, simple preparation process and convenient installation of the backboard.
