[0048] The following is combined Figures 1-7 This invention describes a gas storage system. The gas storage system includes: a double-layer gas storage membrane 100, a membrane pressing device 200, a fastening device 300, an air inlet device 400, and an exhaust device 500.

[0049] The double-layer gas storage membrane 100 includes an inner membrane 101 and an outer membrane 102. The outer membrane 102 is located outside the inner membrane 101 and forms a cavity for filling gas between them. The outer membrane 102 has an air inlet duct 111 and an air outlet duct 112 on its outer side. The air inlet duct 111 has an air inlet 103, and the air outlet duct 112 has an air outlet 104. The air inlet duct 103 and the air outlet 104 are connected to the cavity. A membrane pressing device 200 is located on the outside of the double-layer gas storage membrane 100, and the membrane pressing device 200 has an assembly hole; a fastening device 300 passes through the assembly hole of the membrane pressing device 200 to fix the double-layer gas storage membrane 100 to the mounting surface through the membrane pressing device 200; an air inlet device 400 is connected to an air inlet 103; an air outlet device 500 is connected to an air outlet 104 and is used to cooperate with the air inlet device 400 to adjust the pressure between the inner membrane 101 and the outer membrane 102.

[0050] Specifically, the double-layer gas storage membrane 100 consists of an inner membrane 101 and an outer membrane 102, forming a cavity between them for filling with gas. This cavity can be filled with air or an inert gas. An air inlet device 400 injects gas into the space between the inner membrane 101 and the outer membrane 102 through an air inlet 103, and an air outlet device 500 exhausts gas from the space between the inner membrane 101 and the outer membrane 102 through an air outlet 104. The cooperation of the air inlet device 400 and the air outlet device 500 achieves pressure regulation between the inner membrane 101 and the outer membrane 102. Generally, the pressure is maintained between 200-400 Pa to protect the outer membrane 102.

[0051] Specifically, the air inlet duct 111 and the air outlet duct 112 are located on the outer membrane 102. Multiple air inlets 103 are formed at the intersection of the air inlet duct 111 and the outer membrane 102; multiple air outlets 104 are formed at the intersection of the air outlet duct 112 and the outer membrane 102. Both the air inlets 103 and the air outlets 104 are quincunx-shaped and are joined by thermal sealing of the membrane material to achieve low resistance and protect the membrane. The air inlet duct 111 is connected to the air inlet device 400, and the air outlet duct 112 is connected to the air outlet device 500, enabling air intake and exhaust within the cavity, thereby achieving pressure regulation between the inner membrane 101 and the outer membrane 102.

[0052] Furthermore, the gas storage system of this utility model is also equipped with a condenser 107, a positive pressure protector 108, an observation window 109, and a lightning rod 110.

[0053] The double-layer gas storage membrane 100 of this invention uses a pressing device 200 and a fastening device 300 to fix it to the mounting surface, replacing the existing fixing method that requires the installation of embedded parts. This fixing method eliminates the need for embedded parts, making installation quick and convenient. The original installation method required pre-processing embedded parts, transporting them to the site, and then installing them. This invention eliminates the need for pre-processing and assembling embedded parts; it can be installed using the existing pressing device 200 and fastening device 300, saving time and reducing costs.

[0054] This utility model provides a gas storage system, which includes: a double-layer gas storage membrane 100, a membrane pressing device 200, a fastening device 300, an air inlet device 400, and an air outlet device 500. The double-layer gas storage membrane 100 includes an inner membrane 101 and an outer membrane 102. The outer membrane 102 is disposed outside the inner membrane 101 and forms a cavity between them. An air inlet duct 111 and an air outlet duct 112 are provided on the outer side of the outer membrane 102. The air inlet duct 111 is provided with an air inlet 103, and the air outlet duct 112 is provided with an air outlet 104. The air inlet duct 103 and the air outlet 104 are connected to the cavity. A pressure-pressing device 200 is located on the outside of the double-layer gas storage membrane 100, and the pressure-pressing device 200 has mounting holes. A fastening device 300 passes through the mounting holes of the pressure-pressing device 200 to fix the double-layer gas storage membrane 100 to the mounting surface via the pressure-pressing device 200. An air inlet device 400 is connected to an air inlet duct 111. An air outlet device 500 is connected to an air outlet duct 112 and is used in conjunction with the air inlet device 400 to adjust the pressure between the inner membrane 101 and the outer membrane 102. The gas storage system provided by this utility model, through the cooperation of the air inlet device 400 and the air outlet device 500, achieves pressure regulation between the inner membrane 101 and the outer membrane 102, protecting the outer membrane 102; the use of the pressure-pressing device 200 and the fastening device 300 to fix it to the mounting surface replaces the fixing method of installing embedded parts in the prior art, saving construction time and reducing costs.

[0055] In one embodiment of this utility model, the gas storage system further includes an air inlet duct 105 and an air outlet duct 106. The air inlet duct 105 is located outside the air inlet duct 111 and connects the air inlet duct 111 and the air inlet device 400; the air outlet duct 106 is located outside the air outlet duct 112 and connects the air outlet duct 112 and the air outlet device 500. Specifically, the outer membrane 102 has quincunx-shaped holes on its inner side, allowing air to enter and exit to its inner side (i.e., the outer side of the inner membrane 101).

[0056] In one embodiment of this utility model, the exhaust device 500 includes: a connecting pipe 506, a flap 501, and a counterweight 502. The connecting pipe 506 is connected to the exhaust duct 106; the flap 501 is rotatably disposed inside the connecting pipe 506; the counterweight 502 is disposed on the flap 501, and the exhaust airflow is controlled by the rotation angle of the flap 501. Specifically, the exhaust airflow is controlled by the opening angle of the flap 501. The counterweight 502 is fixed to the flap 501 by bolts and nuts to increase its weight. Different weights of counterweights 502 can be installed as needed to adjust the difficulty of rotating the flap 501, thereby controlling the exhaust airflow. Understandably, when the pressure between the inner membrane 101 and the outer membrane 102 is low, it is insufficient to drive the flap 501 to rotate. At this time, the flap 501 seals the connecting pipe 506 and does not exhaust air. When the pressure between the inner membrane 101 and the outer membrane 102 is high enough, it drives the flap 501 to rotate. The flap 501 and the connecting pipe 506 form a gap for air supply and exhaust. Based on the pressure between the inner membrane 101 and the outer membrane 102, the angle of rotation of the flap 501 can be controlled, thereby controlling the exhaust air volume.

[0057] In one embodiment of this utility model, the exhaust device 500 further includes a blocking plate 503 and a mounting bracket 504. The blocking plate 503 is disposed inside the connecting pipe 506 and has a mounting hole; the mounting bracket 504 is sealed within the mounting hole, and the flap 501 is rotatably disposed on the mounting bracket 504 and can be tilted onto the mounting bracket 504. Specifically, the outer surface of the blocking plate 503 is sealed to the inner side of the connecting pipe 506, and its inner surface forms a mounting hole. The mounting bracket 504 is sealed within the mounting hole and is used to install the flap 501. Through the structure of the blocking plate 503 and the mounting bracket 504 in this embodiment, the sealing of the connecting pipe 506 is ensured when the flap 501 is closed.

[0058] Preferably, the mounting bracket 504 has a trapezoidal block structure on the side. When the flap 501 is attached to the mounting bracket 504, it is inclined to the axial direction of the connecting pipe 506, so that the flap 501 can rotate under the exhaust pressure.

[0059] In one embodiment of this utility model, the exhaust device 500 further includes a hinge 505, which is disposed between the mounting frame 504 and the flip plate 501. Specifically, by disposing of the hinge 505 between the mounting frame 504 and the flip plate 501, the flip plate 501 is rotatably connected around the hinge 505.

[0060] In one embodiment of this utility model, the pressing device 200 includes: a right-angle steel having a first side and a second side perpendicular to each other, the first side and the second side being pressed onto the outer membrane 102 respectively, the second side being parallel to the mounting surface, and an assembly hole being provided on the second side. Specifically, by pressing the first side and the second side of the right-angle steel onto the outer membrane 102, with the second side parallel to the mounting surface, a fastening device 300 passes through the assembly hole on the second side and the double-layer gas storage membrane 100, and is inserted into the mounting surface to achieve a pressing and sealing of the double-layer gas storage membrane 100.

[0061] In one embodiment of this utility model, multiple right-angle steels are provided, and the multiple right-angle steels are arranged to form a polygonal structure that is pressed onto the outer membrane 102. In order to ensure the fixation effect of the double-layer gas storage membrane 100, multiple right-angle steels are used to fix it. Depending on the actual situation, the multiple right-angle steels are arranged to form a hexagonal or octagonal structure.

[0062] In one embodiment of this utility model, the fastening device 300 includes an expansion bolt that passes sequentially through the right-angle steel and the double-layer gas storage membrane 100. Specifically, by installing the expansion bolt, the right-angle steel is used to fix the double-layer gas storage membrane 100.

[0063] In one embodiment of this utility model, the exhaust duct 112 and the air inlet duct 111 are respectively located on both sides of the outer membrane 102, and the angle between the exhaust duct 112 and the air inlet duct 111 in the circumferential direction of the outer membrane 102 ranges from 120° to 180°. Preferably, the angle between the exhaust duct 112 and the air inlet duct 111 is 180°, that is, they are arranged opposite each other on both sides of the outer membrane 102.

[0064] In one embodiment of the present invention, the air intake device 400 includes a fan that blows air between the inner membrane 101 and the outer membrane 102.

[0065] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
