[0024] like Figures 1 to 5As shown, a double-membrane gas storage cabinet device comprises a bottom membrane 6, an outer membrane 1 is fixedly connected to the top of the bottom membrane 6, a delivery pipe 3 is fixedly connected to the outer membrane 1, an inner membrane is fixedly sleeved inside the bottom membrane 6, an output pipe 4 is fixedly connected to one side of the inner membrane, a base 2 is installed at the bottom of the bottom membrane 6, a blower 7 is installed on the upper surface of the base 2, an output end of the blower 7 is connected to a delivery pipeline 5 for delivering and extracting air inside the pressure regulating space, and a disassembly assembly 9 for connecting to a fixed support frame 8 is provided on the delivery pipe 3;

[0025] Specifically, the disassembly and assembly component 9 can be set up to assemble and fix the delivery pipe 5 on the delivery pipe 3, so as to facilitate the delivery and extraction of air in the pressure regulating space formed between the outer membrane 1 and the inner membrane. Compared with the threaded connection method, the stability of the delivery pipe 5 installed on the delivery pipe 3 is effectively improved, the normal use of the delivery pipe 5 is ensured, the accidental leakage of the delivery pipe 5 during the transmission process is avoided, and the controllability and stability of the pressure regulating space during use are guaranteed.

[0026] like Figure 1 and Figure 5 As shown, a support frame 8 for supporting the conveying pipeline 5 is installed on the top of the base 2;

[0027] Specifically, the support frame 8 is set to normally support the conveying pipe 5, so that the outer wall surface of the conveying pipe 5 will not fit the outer membrane 1, thereby not causing pressure on the outer membrane 1, effectively avoiding the need for the blower 7 to fight against the pressure produced by the conveying pipe 5 on the outer membrane 1 when the gas inside the inner membrane decreases and the shape of the outer membrane 1 changes, thereby reducing the extra energy and power required for the blower 7 to transport air.

[0028] like Figures 2 to 4 As shown, the disassembly assembly 9 includes a connection block 1 906 and a connection block 2 907, the outer walls of the delivery pipe 5 and the delivery pipe 3 are respectively fixedly connected with two connection blocks 1 906 and two connection blocks 2 907, the other ends of the two connection blocks 1 906 and the two connection blocks 2 907 are respectively welded with a fastening ring 1 901 and a fastening ring 2 902, the outer wall of the delivery pipe 5 is bonded with a sealing gasket 903, and the side wall of the delivery pipe 3 is provided with a sealing groove 904 for storing the sealing gasket 903, and a fastening portion 905 for enhancing the connection fastness between the delivery pipe 3 and the delivery pipe 5 is provided between the fastening ring 1 901 and the fastening ring 2 902, and the sealing gasket 903 is made of soft rubber material;

[0029] Specifically, by inserting the sealing gasket 903 into the sealing groove 904, the sealing gasket 903 can be deformed accordingly during the process, thereby enhancing the sealing effect of the connection between the delivery pipe 5 and the delivery pipe 3, and preventing air from leaking or penetrating at the connection.

[0030] like Figures 2 to 4 As shown, the fastening portion 905 includes a sliding groove 1 9052 and a sliding groove 2 9053. The side walls of the fastening ring 1 901 and the fastening ring 2 902 are respectively provided with a sliding groove 1 9052 and a sliding groove 2 9053. Two sliding blocks 9051 with wide ends and narrow middle are arranged on adjacent sides of the fastening ring 1 901 and the fastening ring 2 902. The two ends of the sliding block 9051 can be slidably connected to the inside of the sliding block 9051 and the sliding groove 2 9053. The fastening ring 2 902 is provided with an interception portion 10 for intercepting and fixing the sliding block 9051.

[0031] Specifically, by installing the two sliding blocks 9051 inside the sliding groove 1 9052, when the sealing gasket 903 is inserted into the sealing groove 904, the sliding block 9051 is rotated so that the other ends of the two sliding blocks 9051 can be rotated to the inside of the sliding groove 2 9053, thereby enhancing the tightness of the connection between the fastening ring 1 901 and the fastening ring 2 902, preventing the delivery pipeline 5 from shaking or even loosening due to the flow impact of the gas when transporting the gas, thereby ensuring the stability and firmness of the delivery pipeline 5 when in use.

[0032] like Figure 4 As shown, a blocking ring 9054 is fixedly installed inside the second sliding groove 9053;

[0033] Specifically, the blocking ring 9054 can intercept and block the two sliding blocks 9051 to prevent the two sliding blocks 9051 from completely rotating into the second sliding groove 9053, thereby ensuring the connection effect of the sliding block 9051 between the fastening ring 1 901 and the fastening ring 2 902.

[0034] like Figure 4 As shown, the intercepting portion 10 includes a side plate 101 and a side plate 102, and the two ends of the fastening ring 902 are both installed with the side plate 101 and the side plate 102, and a screw 103 is threadedly connected between the side plate 101 and the side plate 102, and a through hole 104 for the screw 103 to pass through is opened on the sliding block 9051;

[0035] Specifically, by sequentially passing the screw 103 through the side plate 101, the through hole 104 and the side plate 102, the screw 103 can be installed and fixed. At this time, the screw 103 can limit the placement position of the sliding block 9051, preventing the sliding block 9051 from rotating during use or even sliding out of the sliding groove 1 9052 or the sliding groove 2 9053, thereby enhancing the stability of the sliding block 9051 during use.

[0036] When in use, the user can insert one end of the delivery pipe 5 into the interior of the delivery pipe 3. During the movement of the delivery pipe 5, the sealing gasket 903 can be squeezed into the interior of the sealing groove 904. The sealing gasket 903 is deformed during the movement, thereby ensuring the sealing effect of the connection between the delivery pipe 3 and the delivery pipe 5. Then, the user can rotate the two sliding blocks 9051 into the interior of the sliding groove 1 9052, and then pull the two sliding blocks 9051 respectively, so that the two ends of the sliding blocks 9051 are simultaneously located in the interior of the sliding groove 1 9052 and the sliding groove 2 9053, thereby enhancing the stability of the sealing gasket 903 inserted into the interior of the sealing groove 904 and enhancing the safety of the delivery pipe 5. The firmness and stability of the screw 103 installed on the conveying pipe 3, and at this time the blocking ring 9054 can block the side of the sliding block 9051 located inside the sliding groove 9053, preventing the sliding block 9051 from completely sliding into the sliding groove 9053, ensuring the stability of the sliding block 9051 when in use, and ensuring the tightness and firmness of the connection between the fastening ring 1 901 and the fastening ring 2 902. Finally, the user rotates the screw 103 through the side plate 101, the through hole 104 and the inside of the side plate 2 102 in turn, which can realize the installation and fixation of the screw 103. At the same time, the screw 103 set can also enhance the installation of the sliding block 9051 in the sliding groove 9 052 and the stability of the inside of the sliding groove 9053, and then start the blower 7 to transport air to the pressure regulating space formed between the outer membrane 1 and the inner membrane through the conveying pipe 5. When the pressure inside the inner membrane is balanced with the pressure between the outer membrane 1 and the inner membrane, the bottom membrane 6 stops working. Since the output pipe 4 and the inner membrane are fixedly connected, when the gas in the outer membrane 1 is used, the gas can be output to the outside through the output pipe 4. When not in use, the output end of the output pipe 4 can be sealed with a sealing plug. During the gas output process, the inner membrane retracts. At this time, start the blower 7 to transport air to the conveying pipe 3 through the conveying pipe 5. The support frame 8 provided can support the conveying pipe 5. The extra energy and power required for the blower 7 to transport air is reduced (the transport pipe 5 directly suspended on the outer membrane 1 will generate pressure on the outer membrane 1 to prevent the shape of the outer membrane 1 from changing when the methane in the inner membrane space decreases. When the blower 7 transports air to the pressure regulating space, it is necessary to counteract the pressure of the transport pipe 5 on the outer membrane 1, and the blower 7 requires more power). When the air pressure is balanced, the bottom membrane 6 is stopped (in actual use, a pressure detector connected to the blower 7 with an electric wire is provided on the outside, and the pressure detector is connected to the pressure alarm device through electric wires. Therefore, when the pressure detector detects the pressure change in the pressure regulating space, the bottom membrane 6 can be controlled in real time and the user can be reminded).

[0037] In summary: through the provided disassembly and assembly component 9, the delivery pipe 5 can be assembled and fixed on the delivery pipe 3, which is convenient for conveying and extracting the air in the pressure regulating space formed between the outer membrane 1 and the inner membrane. Compared with the threaded connection method, the stability of the delivery pipe 5 installed on the delivery pipe 3 is effectively improved, the normal use of the delivery pipe 5 is ensured, the accidental leakage of the delivery pipe 5 during the transmission process is avoided, and the controllability and stability of the pressure regulating space during use are guaranteed.
