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 concentrated solar device which comprises a reflector structure, a receiving device and cover plate glass. The reflector structure comprises a primary reflector for receiving solar rays, and a secondary reflector for receiving the solar rays reflected by the primary reflector. 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 located in the reflective light path of the secondary reflector to receive the solar rays reflected by the secondary reflector. The reflector structure, the receiving device and the cover plate glass form a sealed concentrated unit. The concentrated solar device is reliable in performance, high in intensity, low in cost and long in service life, can be arranged in array and can be applied in large scale.

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...
