The invention discloses a shading and condensing device for a vacuum tube. The device comprises first rotating wheels arranged on the two ends of the vacuum tube, wherein the first rotating wheels can rotate around the vacuum tube, a second rotating wheel is sleeved at the inner side of each first rotating wheel, the first rotating wheels and the second rotating wheels can rotate relative to eachother, the inner end face of each first rotating wheel is fixedly provided with a fixed block, the radial outward protruding part of each fixed block is used for blocking the corresponding second rotating wheel, the axial bulging part or / and fixed block of the second rotating wheel on one end of the vacuum tube is / are used for fixing one end of a reflector plate, and the axial bulging part or / and fixed block of the second rotating wheel on the other end of the vacuum tube is / are used for fixing the other end of the reflector plate. The device provided by the invention is suitable for being installed on a vacuum tube collector or a water heater, the reflector plate can be arranged below the vacuum tube and used for condensing light in a heat collecting process, thus the heat collection efficiency can be improved; and the reflector plate can be turned above the vacuum tube and used for shading the sunlight in a sunshading process, thus the problem of overheating solar energy products can be better solved.
Description
technical field [0001] The invention relates to the field of solar photothermal technology, in particular to a sunshade concentrating device for vacuum tubes. Background technique [0002] At present, countries around the world are advocating energy conservation and emission reduction, and making full use of renewable energy. Driven by this orientation, as the solar energy industry is steadily maturing, solar energy is no longer just providing hot water for bathing, but has begun to enter the comprehensive utilization fields of solar cooling and heating. [0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: in practical applications, there will be a problem of excess heat in spring and autumn when cooling and heating alone or at the same time, and this phenomenon seriously affects Development of the solar industry. In addition, for buildings that are not frequently inhabited, solar products wi...
