[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1-2 , the present utility model provides a technical solution for a fireproof and heat-insulating storage structure for hydrogen cylinders of hydrogen energy: a fireproof and heat-insulating storage structure for hydrogen cylinders of hydrogen energy, including a sealed box 1, a storage chamber 7 is opened in the sealed box 1, a nitrogen chamber 3 is opened on one side of the sealed box 1, a nitrogen cylinder 6 is installed in the nitrogen chamber 3, a nitrogen filling machine 4 is fixedly installed at the top of the nitrogen cylinder 6 in the nitrogen chamber 3, a gas supply pipe 5 is connected from the nitrogen filling machine 4 to the storage chamber 7, a nitrogen chamber maintenance door 2 is installed on one side of the nitrogen chamber 3, several pairs of slide rails 8 are installed in the storage chamber 7, a partition board 10 is movably installed between several pairs of slide rails 8 by using slide ways 9, several bearing platforms 11 are fixedly installed on one side wall surface of the partition board 10, a pair of fixing belts 13 are installed above each bearing platform 11 on the partition board 10, a hydrogen cylinder 12 is placed in the bearing platform 11 and within the fixing belt 13, a sealing door 14 is installed on one side of the storage chamber 7, and a pressure relief valve 15 is installed at the top of the storage chamber 7 and on one side of the sealing door 14.

[0016] Further, the nitrogen filling machine 4 is connected to the nitrogen cylinder 6, and a pressure gauge communicating with the outside is installed in the storage chamber 7.

[0017] Further, heat insulation materials are installed on the inner side wall surfaces of the storage chamber 7.

[0018] Further, the fixing belt 13 adopts a metal chain structure.

[0019] Embodiment: When the device is in use, first open the sealing door 14, then pull out the partition plate 10 from the position of the sealing door 14 through the cooperation of the slide rail 8 and the slideway 9, place the hydrogen cylinder 12 on the bearing platform 11 and then fix it with the fixing belt 13.

[0020] After all the hydrogen cylinders 12 are fixedly installed, push the partition plate 10 back into the interior of the storage chamber 7.

[0021] After all the partition plates 10 are installed, close and seal the sealing door 14.

[0022] Heat insulation materials are installed on the inner side wall surfaces of the storage chamber 7, which can isolate the heat transfer to a certain extent.

[0023] After closing the sealing door 14, inject nitrogen into the storage chamber 7 through the nitrogen filling machine 4 and the nitrogen cylinder 6. The air in the storage chamber 7 is discharged from the pressure relief valve 15 as the nitrogen is injected. The pressure gauge in the storage chamber 7 can display the air pressure to prevent the air pressure from being too high.

[0024] When the storage chamber 7 is filled with nitrogen, it can play a certain fire prevention role. At the same time, due to the existence of the pressure relief valve 15, the air pressure in the storage chamber 7 is slightly higher than the external air pressure, which can also weaken the internal and external air pressure difference of the hydrogen cylinder 12 and prevent the hydrogen cylinder 12 from bursting due to excessive internal pressure.

[0025] When it is necessary to take out the hydrogen cylinder 12, actively relieve the pressure through the pressure relief valve 15. After the air pressure in the storage chamber 7 is balanced, open the sealing door 14, pull out the partition plate 10 from the storage chamber 7 and then take out the hydrogen cylinder 12, which is convenient and fast.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
