[0031] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details given herein, that the present application can be practiced with other different systems, and that the present application is not limited to the details given herein.

[0033] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. The "in one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent or alternative to other embodiments.

[0034] Embodiment 1

[0035] Reference Figures 1-2 For the first embodiment of the present application, the embodiment provides an explosive gas storage tank, which comprises a storage unit 100, including an inner tank 101, an outer tank 102 arranged outside the inner tank 101, and a plurality of support tables 103 arranged below the outer tank 102.

[0038] It should be noted that the tank body is a double-layer structure composed of the inner tank 101 and the outer tank 102, both of which are horizontal cylindrical storage tanks, and the support tables 103 are specifically two, the upper surfaces of which are arc surfaces consistent with the curvature of the outer tank 102, and the outer tank 102 is stably arranged above the two support tables 103.

[0039] Preferably, the cooling pipeline 201 is spiral-shaped, fixedly connected between the inner tank 101 and the outer tank 102, and penetrates and is fixedly connected on both sides of the cooling liquid circulating pump 202. The cooling liquid circulating pump 202 can drive the cooling liquid in the cooling pipeline 201 to circulate and cool, and by using the principle of thermal expansion and contraction, the activity of the explosive gas in the tank can be reduced under high pressure, making it more stable.

[0040] Preferably, the inner tank 101 and the interlayer of the outer tank 102 are filled with an explosion inhibitor, in this embodiment, carbon dioxide. When the hydrogen storage tank is accidentally hit, dropped or crushed, which may cause the stored high-pressure hydrogen to leak, when the hydrogen leaks, the hydrogen will first mix with the carbon dioxide in the interlayer to form an inert gas mixture, significantly reducing the risk of explosion.

[0041] Embodiment 2

[0042] With reference to Figures 1-4 For the second embodiment of the application, which is different from the first embodiment, it further includes that the inflation interface 301 includes an inflation pipe 301a, a connecting flange 301b arranged on one side of the inflation pipe 301a, and a switching turntable 301c arranged outside the inflation pipe 301a.

[0043] The ventilation assembly 302 includes a round rod 302a, a ventilation groove 302b arranged on the outer surface of the round rod 302a, a piston 302c arranged on one side of the round rod 302a, a through hole 302d arranged on one side of the piston 302c, a spring 302e arranged on one side of the piston 302c, and a limiting torsion bar 302f arranged on one side of the piston 302c.

[0046] In use, the external high-pressure inflator is connected to the inflation interface 301 through the connecting flange 301b by bolting. After connection, the external device starts to inflate and pressurize the inflation interface 301. The pressure can stretch the spring 302e to separate the piston 302c from the outer tank 102. When the pressure is sufficient, the piston 302c leaves the outer tank. At this time, the gas can flow to the switching valve 303 through the following path: external inflator device-inflation pipeline 301a-vent groove 302b-vent hole 302d-switching valve 303.

[0047] In summary, the design is convenient for inflating the gas tank. In the absence of pressure, the air in the tank cannot overflow. When pressurized, the tank can be inflated through a series of paths, making the inflation safer and more reliable.
