[0002] Hydrogen gas storage tanks are equipment specifically used to store gas and also serve to stabilize system pressure. They can be divided into different types according to the pressure they can withstand. There are many types of hydrogen gas storage tanks available, such as:

[0003] Publication number CN114623382A discloses a safety explosion-proof gas storage tank, which is provided with a sealed cavity on the outside of the tank body of the gas storage tank. Through the coordinated use of an explosive gas detection device, a processor, an alarm and an indicator light, when the explosive gas detection device detects dangerous gas, the signal is transferred to the alarm and the indicator light through the processor, which can timely avoid the occurrence of explosion accidents and is safer to use. However, the above device still has certain shortcomings when used. When the gas storage tanks are transported and delivered, the transportation of multiple groups of gas storage tanks may cause collisions between the gas storage tanks. At this time, the collision between the gas storage tanks may cause damage to the hydrogen energy gas storage tank and gas leakage. Therefore, the above device cannot perform good protection when transporting the hydrogen energy gas storage tanks.

[0004] Therefore, we proposed a high-protection hydrogen gas storage tank that can solve the above problems well. Utility Model Content

A set of inflatable airbags 5021 are adhered to one end of the interior of the docking sleeve 502. Several cams 5022 are fixed to the inside of one end of the inflatable airbags 5021. The outside of the inflatable airbags 5021 is connected to one end of the gas pipeline 4. The interior of the second positioning member 6 includes a second screw 601 threadedly connected to the middle of the front protective bracket 2. A set of positioning protrusions 602 are fixed to one end of the second screw 601. A positioning groove 603 is fixed between two adjacent sets of positioning protrusions 602. The diameter of the positioning protrusions 602 is smaller than the diameter of the positioning groove 603. The number of the positioning grooves 603 is the same as the number of the convex keys 5022 fixed on one side of the expansion airbag 5021. The positioning grooves 603 form a locking mechanism between the convex keys 5022 and the positioning protrusions 602, and the outer side of the positioning protrusions 602 can extend into the inner position of the docking groove 503.

[0031] First, two or more groups of hydrogen energy storage tank bodies 1 are placed flush, and then the first positioning member 5 and the second positioning member 6 are rotated so that the first screw 501 set inside the first positioning member 5 is rotated and moved in the protective bracket 2 on the rear side, and the second screw 601 set inside the second positioning member 6 is rotated and moved in the protective bracket 2 on the front side, so that the positioning protrusion 602 and the positioning groove 603 fixed at one side of the second screw 601 extend into the docking groove 503 opened inside the docking sleeve 502. At this time, one end of the gas pipeline 4 is processed for gas transmission, and the valves set at both sides of the protective bracket 2 are ensured to be closed. At this time, the gas pipeline 4 is internally The gas will be transported to the interior of the first positioning member 5. At this time, the expansion airbag 5021 provided inside the first positioning member 5 causes the expansion airbag 5021 to expand inside the first positioning member 5, so that the convex key 5022 provided on the outside of the expansion airbag 5021 will expand and slide inside the first positioning member 5. At this time, the outer side of the convex key 5022 will be embedded in the internal position of the positioning protrusion 602 and the positioning groove 603, which can facilitate the limited movement of the positioning groove 603 and the positioning protrusion 602, thereby avoiding the phenomenon of two or more groups of hydrogen energy storage tank bodies 1 colliding with each other during transportation.

A set of piston blocks are fixed to the end of the exhaust pipe 7 that extends into the accommodating tube 9. A set of air outlets are opened at the position of the piston blocks in the exhaust pipe 7. The accommodating tube 9 slides between the air outlets of the exhaust pipe 7 and the interior of the exhaust pipe 7.

[0033] By closing the valve connected to the first positioning member 5 on one side of the gas pipeline 4, the valve connected to the side of the leg support 3 on the gas pipeline 4 can be opened at this time, so that the gas is transported to the inside of the leg support 3 through the gas pipeline 4. Since one end of the gas pipeline 4 is connected to the middle position of the exhaust pipe 7, and a piston is provided at the gas outlet position of the exhaust pipe 7, and the exhaust pipe 7 is provided in the internal position of the accommodating tube 9, the accommodating tube 9 will be extended by the extension member 10 at this time, so that the accommodating tube 9 drives the extension member 10 to extend its position inside the leg support 3. At this time, by increasing the contact area, the hydrogen energy storage tank body 1 is placed more stably, and the hydrogen energy storage tank body 1 is more effectively protected.
