Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of membrane structure heat preservation, specifically relates to an energy-saving air bag convenient for light transmission and light shielding switching. BACKGROUND

[0002] In response to the national "low carbon environmental protection" appeal, while reducing the operating cost of air-supported membrane structure, the air-supported membrane structure usually reserves 10% of the area to use light-transmitting membrane material in the design, which is commonly known as "skylight" in the industry. The "skylight" is similar to the window of a conventional building, which can allow sunlight to pass through. The existence of the "skylight" can ensure that the indoor lighting reaches the same brightness as when the light is on at night, thereby saving lighting costs. However, this structure has obvious drawbacks in actual use in summer and winter.

[0003] Compared with the remaining 90% of the area of the air-supported membrane structure, the "skylight" area is not filled with thermal insulation materials to ensure light transmission. In hot summer weather, under the double effects of heat conduction and heat radiation, the temperature inside the venue is high, increasing the cooling energy consumption, especially when the sunlight directly hits the human body through the skylight, making the body feel hot and easily causing people to feel irritated. In cold winter weather, hot air rises, and the "skylight" is located at the top of the air membrane, so a large amount of heat is lost through this area, increasing the heating energy consumption.

[0004] The main body of the air-supported membrane structure is mainly composed of membrane material, which is a flexible woven material that cannot withstand large concentrated loads. This characteristic of the membrane material makes it impossible to fix the conventional light shielding structure on the main body of the air membrane. SUMMARY

[0005] Therefore, the utility model provides an energy-saving air bag convenient for light transmission and light shielding switching, which can not only play a role in shading and energy saving in summer, but also play a role in light transmission and heat preservation in winter, and has the advantages of simple structure, convenient operation and low manufacturing cost.

[0010] Further, the light-transmitting air bag is connected with a gas supply pipeline, the gas supply pipeline is connected with a three-way valve, and the gas supply pipeline is connected with a gas supply unit through the three-way valve.

[0011] Further, the light-blocking air bag is connected with a gas supply pipeline, the gas supply pipeline is connected with a three-way valve, and the gas supply pipeline is connected with a gas supply unit through the three-way valve.
