Embodiment Construction

[0046] figure 1 It is a structural schematic diagram of the concentrating solar energy device of the present invention. figure 1 Schematic diagram showing the cross-section or rotating section of the concentrating solar device 1, which mainly includes a reflector structure 2, a receiving device 5 and a cover glass 6, wherein the reflector structure 2 is composed of two curved mirrors, which are respectively primary reflectors 3 and secondary reflector 4. The primary reflector 3 is obtained by punching and coating a thin metal sheet; and has a circular focal line; the secondary reflector 4 is arranged in the space of the primary reflector, and is located near two mutually parallel focal lines or an annular focal line, which This layout is conducive to improving the angular tolerance of the entire optical system and reducing the pressure on the precision requirements of the mechanical tracking system. In actual use, the curved mirror of the primary reflector 3 is a part of a p...

Abstract

The invention discloses a concentrating solar energy device, which comprises a reflecting mirror structure, a receiving device and a cover glass. The reflector structure includes a primary reflector for receiving sunlight; a secondary reflector for receiving the sunlight reflected by the primary reflector. Wherein the secondary reflector is arranged in the space of the primary reflector. The receiving device is arranged at the bottom of the primary reflector, and is located at the position of the reflected light path of the secondary reflector, and receives the sunlight reflected by the secondary reflector. Wherein the reflector structure, the receiving device and the cover glass form a closed light concentrating unit. The invention has reliable structural performance, high strength, low cost and long service life, and can be installed in an array for large-scale application.

Description

technical field [0001] The invention relates to a concentrated solar energy device. Background technique [0002] As a kind of clean and environment-friendly energy, solar energy has been devoted to its development and utilization for a long time. Especially in recent years, due to the rising oil price and the improvement of environmental protection requirements, as well as the limitation of atmospheric carbon dioxide emissions, countries have worked harder to carry out research on solar energy utilization, which is critical to the key components of solar energy application equipment, especially It is the efficiency of solar energy reception and the manufacturing cost that put forward higher requirements. Spotlight has the advantage of low cost, but optical tracking is expensive. There are two main types of optical concentrating systems: transmission concentrating and reflective concentrating; the transmissive mirror is mostly made of organic materials; the reflective conc...
