Solar reflection plate

Abstract

The invention discloses a solar reflection plate which comprises a framework, a circular disk and a control system. The framework is formed by memory alloys crossed vertically and horizontally; the circular disk is formed by multiple memory alloy panels arranged on the framework, and can be folded and concave-convex deformed; and the control system is arranged in the center of the circular disk and is used for controlling the deformation of the circular disk according to a received ground signal. When in use, the reflection plate provided by the invention is emitted to a geosynchronous earth orbit; during emitting, the circular disk is folded to the minimum volume so as to be emitted into the geosynchronous earth orbit and is then unfolded to be used; when in use, a control signal is emitted to the reflection plate through a ground base station, and heat is produced through an emitting device, so that the circular disk formed by the shape memory alloys is concave-convex deformed in theshape, and is deformed to form a pan shape; and solar energy is reflected onto the earth through a light-reflective reflecting layer on the surface of the circular disk so as to be secondarily utilized, so that the energy and grain problems caused by insufficient light irradiation in partial areas are solved.

Description

technical field [0001] The invention belongs to the field of solar energy applications, in particular to a solar reflector. Background technique [0002] Solar energy is an indispensable source of energy for people's lives, but some areas are limited by the climate and the light time is short, resulting in energy shortages in some areas, and because these areas cannot receive sufficient light, plants cannot grow normally, and serious food problems have emerged . Contents of the invention [0003] Aiming at the above deficiencies in the prior art, the present invention proposes a solar reflection plate capable of secondary utilization of solar energy. [0004] For achieving the above object, technical scheme of the present invention is: [0005] A solar reflector, comprising: [0006] Skeleton, said skeleton is made of memory alloy intersecting vertically and horizontally; [0007] A disk, the disk is composed of several memory alloy plates installed on the skeleton, an...
