Solar energy beam concentration and light focusing control system

Abstract

The invention relates to a solar energy beam concentration and light focusing control system. The solar energy beam concentration and light focusing control system comprises a mirror array for tracing the sun in real time and a solar thermal collector for receiving beam concentration light beams. The mirror array is provided with collecting mirror units, wherein the number of the collecting lens units is M lines * N rows, each collecting lens unit comprises a paraboloid collecting mirror and an upper layer reflecting mirror, and the bottom portion of the paraboloid collecting lens is provided with a through hole. A middle layer first reflecting mirror is arranged in the direction of the light path of each through hole, a middle layer second reflecting mirror is arranged in the direction of the light path reflected through each middle first reflecting mirror. The middle first layer reflecting mirrors and the middle layer second reflecting mirrors can enable M*N light beams on the upper layer to be gathered to form dense balanced light beams. The lower layer reflecting mirrors which enable the dense balanced light beams to be reflected to the solar thermal collector are arranged in the direction of the light path of the dense balanced light beams. The solar energy beam concentration and light focusing control system enables mirror array light beams to be concentrated,reduces control points, simplifies maintenance and installation, and employs a single integrated circuit to replace a complex computer control system.

Description

technical field [0001] The invention relates to a solar energy concentration control system, which is widely used in the fields of solar thermal power generation, solar air conditioning, heating, hot water and the like. Background technique [0002] In the field of solar thermal utilization, the rotating parabolic reflector has always been the most effective device for concentrating sunlight, but its focus moves with the reflector. This restricts the size and quality of the receiver. If the size is large, it will be difficult to design, manufacture, and install precision. If it is a trough or tower type, it will also block the reflector, and the heavy weight will increase the load on the support rod; at the same time, The heat collection receiver is in a moving state, which is not conducive to the export of energy and the design of heat preservation. In order to solve this problem, people have been working hard to invent a kind of concentrator whose focal position is fixed ...

AI Technical Summary

Problems solved by technology

This method is easy to control one mirror, but two motors are needed to control one mirror, so M×N×2 motors are needed to control the second reflection mirror of M×N mirror arrays

Moreover, for each reflector, there are different controls for latitude and longitude deflection, which is obviously very complicated
