solar concentrator

Abstract

The invention discloses a solar concentrating sheet, which comprises a back support plate with a square curved surface structure and a sunlight reflection plate, the sunlight reflection plate is bonded to the surface of the back support plate, and also includes a plurality of connecting rods and more than three installation bolts , the back side of the back support plate is fixedly connected with a plurality of arc-shaped ribs, and the plurality of arc-shaped ribs are connected by a plurality of connecting rods, and more than three mounting bolts are fixedly connected or hinged on the connecting rods. Each arc-shaped back rib is provided with more than two process holes, and the corresponding process holes are located at the equal radius of the sector formed by the arc-shaped back ribs. The light concentrating sheet of the present invention is light in weight and high in rigidity, is suitable for any batch production order, has low production cost, high light concentrating precision, is easy to control, and has a long service life as a whole.

Description

technical field [0001] The invention relates to a structure of a solar concentrating sheet. Background technique [0002] The solar concentrating sheet is a component of various solar concentrating devices. The solar concentrating device generally uses multiple solar concentrating sheets to be installed together in a reflective focusing manner to form a precise circular concentrating disc or trough concentrating surface. ; Sunlight shines on solar reflectors, which focus light on a focal point or a focal line, heating objects at the focal point or focal line to very high temperatures; low-cost manufacturing technology for solar concentrators become the bottleneck of industrial development. The industry generally requires solar concentrators to have high concentrating precision, focus size and external dimensions to be manufactured in various ways according to actual conditions, and the relationship between order size and cost can be stably controlled. The traditional solar...

Problems solved by technology

The traditional solar concentrating sheet is designed and manufactured with a whole piece of stamping parts. In small batch non-standard manufacturing, it leads to high mold investment, high production cost, unstable performance, heavy weight, and poor rigidity; in mass manufacturing, stamping products With residual deformation, the shape of the concentrating surface varies with material properties and batches, resulting in uncontrollable residual deformation of the product. The concentrating precision is too low, and the stamping die is not available, resulting in high requirements for material purchase characteristics, increasing costs, and affecting use accuracy and quality. performance
