[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment: Refer to Figures 1-3 a low - energy - consumption thermal insulation air film shown in the figure, including:

[0030] An upper sealing film body 1, and the upper sealing film body 1 is a semi - circular sealing film body with an arc - shaped upper end and a horizontal lower end in cross - section;

[0031] A lower film body 2, and the lower film body 2 is a double - layer film body, and the upper end of the lower film body 2 is fixedly connected to the lower end of the upper sealing film body 1 through a connection structure;

[0032] An internal venue space is formed inside the double-layer film body of the lower film body 2. The sealed inner cavity of the upper sealing film body 1 and the internal venue space of the lower film body 2 are two non-connected cavities.

[0033] A blower 4 is provided outside the lower film body 2 and fills the lower film body 2 and the upper sealing film body 1 with filling gas through a pipeline.

[0034] Furthermore, the upper sealing film body 1 includes a sealed cavity outer film 11 and a sealed cavity diaphragm 12. The sealed cavity outer film 11 is an arc-shaped film, and the sealed cavity diaphragm 12 is a horizontally arranged film body. Both ends of the sealed cavity outer film 11 are fixedly sealed with both ends of the sealed cavity diaphragm 12 respectively.

[0035] Based on the above structure, through the combination of the upper sealing film body 1 and the lower film body 2, the two form an air film building with the same structure and span as the air film hall in the prior art. At the same time, the upper sealing film body 1 is used to form a sealed top space, thereby eliminating the ineffective space above, so that this part does not participate in the gas exchange inside the air film hall, and then reducing the air change rate required when using the fresh air system, while reducing the energy consumption required when the air conditioning system operates, and being able to maintain the high-span ratio of the existing air film hall building, enabling the air film hall to maintain its own mechanical properties and avoiding affecting the safety of the force.

[0036] In this way, on the premise of ensuring safety and reliability, the energy consumption when operating the fresh air system and the air conditioning system in the venue is greatly reduced, achieving the effect of energy conservation and emission reduction.

[0037] It should be noted that in order to improve the use effect of the upper sealing film body 1, an inert gas can also be filled into the upper sealing film body 1 to improve the heat preservation effect of the upper sealing film body 1, or heat preservation cotton can be laid on the inner bottom of the upper sealing film body 1 to ensure its heat preservation performance, reduce the heat exchange between the upper sealing film body 1 and the lower film body 2, and the use effect is better.

[0038] Furthermore, a tension film 3 is preset inside the sealed cavity outer film 11. The upper end of the tension film 3 is fixed to the inner side of the sealed cavity outer film 11, and the lower end of the tension film 3 is fixed to the upper end of the sealed cavity diaphragm 12, so that the sealed cavity diaphragm 12 forms a horizontal hoisting film. By using the tension film 3, it can be avoided that the sealed cavity diaphragm 12 deforms and sags under the action of the internal air pressure and its own gravity after being filled with gas, ensuring the flatness of the sealed cavity diaphragm 12 and providing a stable and effective activity space inside the air film hall.

[0039] Furthermore, the lower film body 2 includes an outer film body 21 and an inner film body 22. Both the lower ends of the outer film body 21 and the inner film body 22 are fixed to the air film foundation, and the upper end of the inner film body 22 is fixed and sealed with the upper end of the outer film body 21.

[0040] Further, the pipeline includes an air outlet pipe 41, a first air inlet pipe 42, and a second air inlet pipe 43. One end of the air outlet pipe 41 is fixedly connected and communicated with the output end of the fan 4. The first air inlet pipe 42 is located between the outer membrane body 21 and the inner membrane body 22 and is provided with air outlet holes. Both ends of the first air inlet pipe 42 are fixedly connected and communicated with one end of the air outlet pipe 41 and one end of the second air inlet pipe 43 respectively;

[0041] The end of the second air inlet pipe 43 far from the air outlet pipe 41 is fixedly connected and communicated with the sealed inner cavity between the sealed cavity outer membrane 11 and the sealed cavity diaphragm 12 at the bottom wall. Solenoid valves are provided on both the first air inlet pipe 42 and the second air inlet pipe 43;

[0042] Thus, the fan 4 can be used to fill the sealed membrane body 1 and the lower membrane body 2 with gas to form a stable air film structure, which is convenient for building an air film hall.

[0043] Further, a first rope edge 111 is formed at the fixed lower end of the sealed cavity outer membrane 11 and the sealed cavity diaphragm 12, and a second rope edge 211 is formed at the fixed upper end of the outer membrane body 21 and the inner membrane body 22;

[0044] The connecting structure includes an anchor bolt 5 and an elastic gasket 6. The anchor bolt 5 passes through the lower end of the sealed cavity outer membrane 11 and the upper end of the outer membrane body 21 to fix the two. Elastic gaskets 6 are attached to both the outer side of the sealed cavity outer membrane 11 and the inner side of the outer membrane body 21. When the anchor bolt 5 is tightened, the two elastic gaskets 6 approach each other and clamp the sealed cavity outer membrane 11 and the outer membrane body 21. The first rope edge 111 is located at the end of the elastic gasket 6 far from the sealed cavity outer membrane 11, and the second rope edge 211 is located at the end of the elastic gasket 6 far from the outer membrane body 21;

[0045] The lower end of the sealed cavity outer membrane 11 and the upper end of the outer membrane body 21 can be fixedly connected by the anchor bolt 5 and the elastic gasket 6, and elastic clamping can be achieved, ensuring connection stability while reducing damage to the air film structure itself.

[0046] Further, an external waterproof strip 7 is fixed to the outer sides of the sealed cavity outer membrane 11 and the outer membrane body 21. The external waterproof strip 7 covers the outside of the anchor bolt 5 and the elastic gasket 6. A flexible deformation part 71 is formed at the fixing place of the lower end of the external waterproof strip 7 and the outer side of the outer membrane body 21. The setting of the external waterproof strip 7 can provide waterproof protection for the connection part of the sealed membrane body 1 and the lower membrane body 2, and the setting of the flexible deformation part 71 enables the external waterproof strip 7 to undergo a certain amount of deformation, thereby avoiding mutual wear or detachment between the external waterproof strip 7 and the air film building when the air film building deforms, and ensuring the effectiveness of the external waterproof strip 7.

[0047] Working principle of the utility model: During daily use, first, the lower end of the outer membrane 11 of the sealing cavity and the upper end of the outer membrane body 21 are fixedly connected through the anchor bolts 5 and the elastic gaskets 6, that is, the upper sealing membrane body 1 and the lower membrane body 2 are fixedly assembled, and the first air inlet pipe 42 and the second air inlet pipe 43 are penetrated and fixed. Then, the air is sent into the sealed inner cavity of the upper sealing membrane body 1 and the inner and outer membrane cavities of the lower membrane body 2 through the fan 4, so that the upper sealing membrane body 1 and the lower membrane body 2 expand to form an air film hall. Through the combination of the upper sealing membrane body 1 and the lower membrane body 2, the two form an air film building with the same structure and span as the air film hall in the prior art. At the same time, the upper sealing membrane body 1 is used to form a sealed top space, thereby eliminating the ineffective space in the upper part, so that this part does not participate in the gas exchange inside the air film hall, thereby reducing the air change rate required when using the fresh air system, reducing the energy consumption required when the air conditioning system operates, and being able to maintain the high-span ratio of the existing air film hall building, so that the air film hall maintains its own mechanical properties and avoids affecting the safety of the force;

[0048] In this way, on the premise of ensuring safety and reliability, the energy consumption of the fresh air system and the air conditioning system in the venue is greatly reduced, achieving the effect of energy conservation and emission reduction.
