Description

Technical Field

[0001] The present invention relates to the technical field of membrane structure heat preservation, and particularly relates to an energy-saving airbag that facilitates the switching between light transmission and light shielding. Background Art

[0002] In response to the country's call for "low-carbon environmental protection" and to reduce the operating costs of air-supported membrane structures, 10% of the area is usually reserved for light-transmitting membrane materials during the design of air-supported membrane structures, which is commonly known as "skylights" in the industry. The "skylights" are similar to the windows of conventional buildings and can allow sunlight to pass through well. The existence of the "skylights" can ensure that the indoor lighting reaches the same brightness as when the lights are on at night during the day, thus saving lighting costs. However, in actual use in summer and winter, there are obvious drawbacks to this structure.

[0003] Compared with the other 90% of the area of the air-supported membrane structure, in order to ensure light transmittance in the "skylight" area, no thermal insulation material is filled in this area. When the weather is hot in summer, under the dual action of heat conduction and heat radiation, the temperature inside the venue is relatively high, increasing the cooling energy consumption. Especially when sunlight shines directly on people through the skylight, the body feels hot and it is easy to make people irritable. When the weather is cold in winter, hot air rises, and the "skylight" is located at the top of the air film, and 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 materials. The membrane materials belong to flexible woven materials and cannot bear large concentrated loads. This characteristic of the membrane materials causes conventional light-shielding structures to be unable to be fixed on the main body of the air film. Summary of the Invention

[0005] In view of this, the present invention provides an energy-saving airbag that facilitates the switching between light transmission and light shielding, which can not only play a role in light shielding and energy saving in summer and light transmission and heat preservation in winter, but also has a simple structure, convenient operation and low manufacturing cost.

[0006] In order to solve the above technical problems, the present invention provides an energy-saving airbag that facilitates the switching between light transmission and light shielding, including, a light-transmitting airbag formed by a light-transmitting membrane material; a light-shielding airbag formed by a light-shielding membrane material; the light-transmitting airbag and the light-shielding airbag form an alternately changing main body.

[0007] Further, the light-transmitting airbag is connected with a gas supply pipeline, the gas supply pipeline is connected with a three-way valve, and is connected with a gas supply unit through the three-way valve.

[0008] Further, the light-shielding airbag is connected with a gas supply pipeline, the gas supply pipeline is connected with a three-way valve, and is connected with a gas supply unit through the three-way valve.

[0009] Further, when the light-transmitting airbag is fully inflated and bulged, the light-shielding airbag is closed.

[0010] Further, when the light-shielding airbag is fully inflated and bulged, the light-transmitting airbag is closed.

[0011] The beneficial effects of the above technical solutions of the present invention are as follows: 1. Based on the "air pillow heat insulation" theory, through the combination of the light-transmitting film material and the light-shielding film material, it plays a role in shading and energy saving in summer and light transmission and heat preservation in winter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will combine the accompanying drawings of the embodiments of the present invention Figures 1-4 , and clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0015] As Figures 1-4 shown: Embodiment

[0016] An energy-saving airbag 3 that facilitates the switching between light transmission and light shielding includes a light-transmitting airbag 1 formed by a light-transmitting film material; a light-shielding airbag 3 formed by a light-shielding film material 4; the light-transmitting airbag 1 and the light-shielding airbag 3 form an alternating transformation main body.

[0017] In this embodiment, the light-transmitting airbag 1 and the light-shielding airbag 3 form a unit and are arranged at intervals. One light-shielding airbag 3 is connected to two light-transmitting airbags 1. The light-transmitting airbag 1 is formed of a light-transmitting film material, and the light-transmitting film material is arranged at the upper and lower ends of the light-transmitting airbag 1, while the light-shielding airbag 3 is arranged on two sides of the light-transmitting airbag 1. The alternate inflation between the light-transmitting airbag 1 and the light-shielding airbag 3 realizes the alternate transformation of the light-transmitting and light-shielding functions. Embodiment

[0018] The light-transmitting airbag 1 is connected to a gas supply pipeline 5. The gas supply pipeline 5 is connected to a three-way valve 6 and is connected to a gas supply unit 7 through the three-way valve 6.

[0019] Different from the above embodiment, in this embodiment, the light-transmitting airbags 1 are connected in parallel by the gas supply pipeline 5, and the gas supply pipeline 5 is connected to a gas supply unit 7 or a gas supply system, and a three-way valve 6 can be added in the middle. Embodiment

[0020] The light-shielding airbag 3 is connected to a gas supply pipeline 5. The gas supply pipeline 5 is connected to a three-way valve 6 and is connected to a gas supply unit 7 through the three-way valve 6.

[0021] Different from the above embodiment, in this embodiment, by the same token, the light-shielding airbag 3 is also connected to a gas supply pipeline 5 and is connected to a gas supply unit 7 or a gas supply system, and the parallel connection method is also adopted. Embodiment

[0022] When the light-transmitting airbag 1 is fully inflated and bulges, the light-shielding airbag 3 is closed.

[0023] Different from the above embodiment, in this embodiment, when light transmission is required, the light-transmitting airbag 1 is filled through the gas supply pipeline 5. While the light-transmitting airbag 1 is being filled, the light-shielding airbag 3 is in a closed state. Embodiment

[0024] When the light-shielding airbag 3 is fully inflated and bulges, the light-transmitting airbag 1 is closed.

[0025] Different from the above embodiment, in this embodiment, when light shielding is required, the light-shielding airbag 3 is filled through the gas supply pipeline 5. While it is being filled, the light-transmitting airbag 1 is closed.

[0026] The working method (or working principle) of the present invention: When this technology is working, in summer, under the action of the control system, the direction of the gas supply pipeline 5 is switched through the "three-way valve 6" to supply gas to the "light-shielding airbag 3" and extract gas from the "light-transmitting airbag 1", and finally form as Figure 2The air cushion shown. At this time, the sealing film material of the "light-shielding airbag 3" is in a stretched state under the action of gas, completely blocking sunlight, and at the same time forming an air pillow with a certain thickness, which has a heat preservation effect. Of course, the "light-shielding airbag 3" can also be in a semi-stretched state through the control system and the air supply unit, that is, it can block part of the sunlight and at the same time have a heat preservation effect, such as Figure 3 shown.

[0027] In winter, under the action of the control system, the direction of the air supply pipeline 5 is switched through the "three-way valve 6" to supply air to the "light-transmitting airbag 1" and extract air from the "light-shielding airbag 3", and finally form an air cushion as shown in Figure 4 shown. At this time, the sealing film material of the "light-shielding airbag 3" is in a tensioned and straightened state under the action of pressure, unable to block sunlight, while the transparent film material is completely opened, allowing sunlight to pass through, and at the same time forming an air pillow with a certain thickness, which has a heat preservation effect.
