Method of collecting sunlight using rotable reflection plate and its device

Abstract

The inventive device comprises a receiving system of sunlight reflected from a sunlight tilt reflection unit and a reflected sunlight receiving unit. A set of reflecting plates is mounted on a tilt reflecting support and the received sunray is reflected on the receiving system. The receiving system and the centre line of each reflecting plate are parallel. The driving mechanical unit mounted on the reflecting support makes the reflecting plates rotate, so as to track the angle change of the sun.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a method and device for gathering sunlight with a rotatable reflecting plate, including a reflecting device for reflecting sunlight and a receiving device for receiving reflected light from the reflecting device. Background technique [0002] In the prior art, solar energy collection and utilization systems are widely used in my country. The solar energy collection system can be used in solar water heaters, or in photovoltaic devices (such as solar cells, etc.), mainly to convert solar energy into thermal energy or electrical energy for users to use. Harvesting devices generally require structurally stable solar collector panels or reflectors and collectors combined using various methods.

AI Technical Summary

Problems solved by technology

[0003] The solar collection system disclosed in invention patent 96193759.9 has simple structure and process, small wind load, and is easy to make a large-scale solar power generation system, but its light leakage rate is high, and the reflectors cover each other heavily, and the reflectors in each group To correspond to two receiving devices, limiting the use of technology

Invention patent 96192810.7 discloses an improved solar collector with a replaceable reflector, which uses a combination of a structurally stable bottom plate mounted on a collector support and a flexible solar reflector, which greatly reduces the difficulty and cost of replacing the reflector, but The manufacturing process of the curved reflector is complicated, and the cost is higher than that of the flat reflector

The improved solar energy collection device disclosed in the invention patent 96192811.5 has a novel focus area, and the collector can be placed in the best position in the focus area during the entire solar cycle. The collector can rotate around the center of curvature of the reflector, but the arc The manufacturing process of the shaped solar reflector is complex, and the collector is placed above the reflector, which will block part of the reflector surface
