Technical Field
[0001] The utility model belongs to the technical field of solar thermal energy, and in particular relates to a retractable dish-type concentrator. Background Art
[0002] Solar energy has the advantages of being clean, pollution-free and renewable. The rational and efficient development and utilization of solar energy is of great significance to the sustainable development of human society. The direct solar radiation energy flux density is low. People usually use the method of concentrating first and then utilizing solar energy. For example, the existing dish concentrator mainly uses the parabolic concentrating principle to concentrate the sunlight irradiated on the parabola to the focus for collection and utilization. The dish concentrator is usually provided with a retractable component, so that the angle of the concentrating dish can be changed. The dish concentrator power generation has high scalability and flexibility. It can be deployed on a large scale and is also suitable for distributed power generation. It is particularly suitable for establishing distributed power stations in water-scarce areas such as deserts and hills, as well as remote islands, rural areas, and pastoral areas. For example, the publication number: CN207849791U discloses a new dish The condenser structure includes a column, a rotating mechanism, a bracket, a back plate, a condenser and a heat absorber. The column and the back plate are connected by a rotating mechanism, and the rotating mechanism drives the back plate to track sunlight; the back plate includes a circular base plate and a plurality of lens seats fixed on the base plate, the lens seat is provided with an annular arc surface, and the axial section of the annular arc surface is a part of a parabola; the condenser is composed of a plurality of lenses, which are tightly fitted on the annular arc surface. The annular arc surface makes the light incident perpendicular to the base plate direction be reflected by the lenses and converged to the focal position, and the focus is the same as the position of the heat absorber. The condenser of the utility model is composed of lenses of different rings, and the mirror surface of each ring is composed of a plurality of mirror surfaces of the same shape arranged closely. The lenses of the same ring only need the same set of molds to be made, which simplifies the production process and improves the focusing efficiency.
[0003] However, there are some problems with the existing technology: although the existing dish concentrator has a high concentration efficiency, which makes it convenient for people to collect and utilize solar energy, in actual use, since the dish concentrator is exposed to the outdoors for a long time, dust often adheres to the mirror surface of the concentrating dish, which will continuously reduce the reflection efficiency of the mirror, thereby directly affecting the overall conversion efficiency and power of the system. Therefore, we propose a retractable dish concentrator. Utility Model Content

[0029] Furthermore, the empty cylinder 3 is fixedly connected to a side box 29, and the rotating mechanism includes a brake motor 14, which is fixedly installed at the bottom of the inner wall of the side box 29.
