Description

Technical Field

[0001] The utility model belongs to the technical field of solar houses and relates to a solar light and heat collection house. Background Art

[0002] The temperature difference between day and night is large in plateau and desert areas. People working and living in these areas often have problems with their normal work and life due to high temperatures during the day or low temperatures at night. The usual solution is to use air conditioning for cooling during the day and auxiliary heating at night, which consumes a lot of energy. This method causes increased energy consumption in houses in plateau and desert areas, and the cost of work and life remains high.

[0003] Therefore, a low-energy consumption house is needed to solve the above problems. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a solar thermal energy collection house, comprising: a house, a focusing lens, an optical fiber bundle, and a heat storage tank. The focusing lens is a concave mirror made of a circular reflective material or a convex lens made of a light-transmitting material. The optical fiber bundle is a light-guiding beam formed by bundling a plurality of optical fibers in parallel. The heat storage tank is an energy storage container storing heat-absorbing and heat-releasing phase change materials. A heat dissipation port is arranged at the lower end of the side wall of the heat storage tank. The heat storage tank is placed indoors in the house, the focusing lens is mounted on the outdoor roof of the house, and the two ends of the optical fiber bundle are respectively connected to the focusing lens and the heat storage tank. The reflection focus of the concave mirror and the rotation axis of the outdoor end of the optical fiber bundle are located in the same straight line, and the refraction focus of the convex lens and the rotation axis of the outdoor end of the optical fiber bundle are located at In the same straight line, the light reflected by the concave mirror or the light refracted by the convex lens converges to the cross-section of the outdoor port of the optical fiber bundle; during the period of strong sunlight during the day, the focusing lens converges the strong light reflected or refracted by the sunlight to the outdoor port of the optical fiber bundle, and the optical fiber bundle transmits the strong light to the heat storage tank inside the house. After the heat storage tank absorbs heat under the strong light, it changes phase and stores thermal energy. After the temperature drops at night, the heat dissipation port of the heat storage tank opens, and the heat storage tank changes phase and releases heat, radiating heat from the heat dissipation port to the house to maintain the indoor temperature; the heat storage tank has a heat storage capacity about 5 times higher than that of water, which can be used for heating people working and living in the house. Therefore, the optical fiber bundle transmits strong light to the room of the house, which can be used for indoor insulation, hot water supply, natural light lighting and other purposes.

[0005] Preferably, the outdoor end of the optical fiber bundle is connected to the bottom of the concave mirror from bottom to top, and a reflector is provided directly in front of the concave mirror. The reflection focus of the concave mirror, the reflection focus of the reflector, and the rotation axis of the outdoor end of the optical fiber bundle are located in the same straight line, and the reflection surface of the concave mirror faces the reflection surface of the reflector, and the reflection surface of the reflector faces the outdoor port cross-section of the optical fiber bundle. The strong light reflected by the concave mirror is reflected secondary to the outdoor end of the optical fiber bundle by the reflector, so that the installation position of the optical fiber bundle is more flexible and changeable, instead of the optical fiber bundle having to be installed on the straight line where the reflection focus of the concave mirror is located. At the same time, due to the continuous change of the position of the sun, the light collection intensity and efficiency of the optical fiber bundle fluctuate greatly. After using the reflector, the area of ​​the reflector is increased, which can improve the collection efficiency of the light reflected by the concave mirror, and reflect more sunlight to the outdoor end of the optical fiber bundle, thereby improving the light collection efficiency.

[0006] More preferably, the reflecting surface of the reflector includes a plane lens, a concave lens, and a convex lens. The reflecting surface of the plane lens is equal to the cross-section of the outdoor port of the optical fiber bundle, the reflecting surface of the concave lens is larger than the cross-section of the outdoor port of the optical fiber bundle, and the reflecting surface of the convex lens is smaller than the cross-section of the outdoor port of the optical fiber bundle. By using different plane lenses, concave lenses, and convex lenses as the reflecting surface of the reflector, the reflector can be installed at different far and near positions on the focal length line of the concave mirror, and the strong light reflected from the concave mirror to the reflector is processed in different ways such as secondary convergence, divergence, and direct reflection, so that the installation position of the reflector and the outdoor port of the optical fiber bundle is diversified, which can adapt to different light collection and installation requirements in different environments.

[0007] More preferably, a fan-shaped notch is provided at the lowest point of the mirror surface of the concave mirror, the notch runs through the front and back mirror surfaces of the concave mirror, and the notch is used to drain rain and snow in rainy and snowy weather.

[0008] Preferably, the outer end of the optical fiber bundling chamber is connected to the bottom of the convex lens from bottom to top.

[0011] Preferably, the house includes a basement.

[0012] The beneficial effects of the utility model are:

[0013] The utility model introduces sunlight into the room through a focusing lens and stores it in a heat storage tank, and then converts the solar energy collected during the day into thermal energy through the phase change heat storage and heat release characteristics of the heat storage tank to heat the machine room at night; or uses the sunlight for indoor lighting through a diffuser, so it can be used for indoor insulation, hot water supply, natural light lighting and other purposes.
