Embodiment Construction

[0024] Fig. 1 is a schematic structural view of a solar concentrating device according to an embodiment of the present invention. As shown in FIG. 1 , the solar concentrating device includes a cylindrical groove support surface 110 , a concentrating mirror array 120 in a joint structure, steel wires 130 , a mechanical transmission control system 140 , an absorbing device 150 and a fixing bracket 160 .

[0025] The support surface 110 of the cylindrical groove has a concave cylindrical shape or a quasi-cylindrical shape, and is composed of several supporting frames (not shown) and some arc-shaped guide rails (not shown). Each arc-shaped guide rail is fixed on the base surface, and its centers are all on a straight line, forming the axis of the cylindrical groove. The support frame is arranged parallel to the axis, and the two ends are limited in the guide rail to form a cylindrical groove support surface. A plane passing through the axis of the cylindrical groove and bisecting...

Abstract

The invention provides a solar concentrator and a condensing method. The solar concentrator includes: a concave cylindrical trough support surface and a condenser mirror array of unified structure matched on the cylindrical trough support surface. The condenser mirror array of unified structure includes a plurality of strip-shaped reflector mirrors; the length of each strip-shaped reflecting mirror is along the axial direction of the cylindrical trough support surface while the width is along the circumferential direction of the cylindrical trough support surface; and all strip-shaped reflecting mirrors are flexibly connected. The invention also includes an absorption device arranged above the cylindrical trough support surface. The condenser mirror array of unified structure is collocated into the shape of sunlight reflected into the size-restricted space of the absorption device; and the condenser mirror array of unified structure revolves the sun and rotates wholly along the circumferential direction of the cylindrical trough; in addition, in the rotating process, the condenser mirror array can maintain the shape of sunlight reflected into the size-restricted space of the absorption device.

Description

technical field [0001] The invention relates to a trough collection system applied to solar energy. In addition to collecting solar energy, it can also be used for other energy transmission and control using waves or radiation as carriers. Background technique [0002] People have been devoting themselves to the development and utilization of solar energy for a long time. Especially in recent years, due to rising oil prices and the requirement to reduce atmospheric carbon dioxide emissions, countries have made greater efforts to carry out research on solar energy utilization. However, solar energy is a low-density, intermittent, and constantly changing energy source in time and space, which is very different from conventional energy sources, which puts forward higher requirements for the collection and utilization of solar energy. [0003] In order to make full use of solar energy, it is first necessary to collect sunlight and track changes in sunlight, and then convert it ...
