Embodiment 1

[0072] Embodiment 1 is a solar building, from figure 2 and Figure 8 The structure of the building can be seen. The frame of the building includes a building front column 11 , a building rear column 15 , and a reflector support 14 . The inner and outer surfaces of the building include floor slabs 20 , inner wall panels 21 , outer wall thermal insulation panels 12 , floors 13 , and shallow arc reflective panels 6 . The shallow arc reflector 6 is fixedly mounted on the reflector bracket 14 .

[0073] The shallow arc reflector 6 includes a reflector upper substrate 28 , a reflector lower substrate 32 and a reflector insulation layer 10 sandwiched therebetween. Please refer to the specific structure of the reflector Figure 9 and Figure 9A . The base plate 28 on the reflector plate and the base plate 32 on the reflector plate are generally stamped from thin plates, and a heat insulating pad 25 can be added between them, and then riveted and fixed. The flat mirror 24 is ad...

Abstract

The invention provides a solar energy utilization device and an application method. A fixed reflector provided with a shallow camber-shaped reflection surface is utilized for reflecting sunlight, and a tracking mechanism is utilized for operating a receiver for tracking the sunlight collected by the reflection of the reflector. By adopting the fixed shallow camber-shaped reflection surface, the solar energy utilization device greatly simplifies the structure, reduces the manufacturing cost and can bear gale and other severe environments, and simultaneously, compared with the existing linear concentration solar device with the fixed reflection surface, the solar energy utilization device can effectively reduce the defocusing degree, thereby achieving a higher concentrating ratio. The reflector comprises a coreboard to which a reflecting layer is attached, and the coreboard comprises an upper base board, a lower base board and an intermediate thermal insulation layer. A tongue-and-groove sealing strip is installed on the lateral surface of the coreboard, and the coreboard can be used as a roof board, a thermal insulation board, a wallboard, a floorboard and the like. The receiver can be a vacuum tube collector or a solar panel. The solar energy utilization device can be fixed on a locking device at a terminal of the reflector under severe weather and other extreme conditions.

Description

technical field [0001] The invention relates to a solar energy utilization device and a use method. Background technique [0002] Solar energy is the most important renewable energy source, but the energy flux density of solar radiation is very low, about 1 kilowatt per square meter. If it is directly converted into heat energy, the temperature of the working medium is low, and only hot water can be produced for bathing, which is of limited use. Flat-panel solar cells can be installed on the roof, do not take up land, and have strong wind resistance, so they have a long life span of up to twenty-five years. However, the cost is also high due to material technology and other reasons. The power generation cost of flat-panel solar cells is much higher than that of biogas power generation, wind power generation and traditional hydropower and coal power, and even more than ten times higher than that of coal power. [0003] Using reflective concentrators to improve the energy f...
