Description

Technical Field

[0001] The utility model relates to the field of hydrogen energy storage equipment, in particular to a graphene magnesium-based solid-state hydrogen storage tank plug interface. Background Art

[0002] A hydrogen storage tank is a container for storing hydrogen. Existing hydrogen storage and transportation container technologies include high-pressure hydrogen storage, liquid hydrogen energy storage, metal hydride hydrogen storage, low-temperature adsorption hydrogen storage, nano-carbon tube high-pressure adsorption hydrogen storage, and liquid organic hydride hydrogen storage. The corresponding hydrogen storage tanks for various hydrogen storage technologies are also different.

[0003] The current mainstream solid-state hydrogen storage tanks / systems are mainly composed of solid-state hydrogen storage materials, stainless steel / aluminum shells, air pipe channels, filters, cooling fins, valves and heating / heat dissipation pipes. Since the pressure of solid-state hydrogen storage tanks is generally lower than 5MPa, higher-cost high-pressure valves are not required.

[0004] The plug interface of the solid-state hydrogen storage tank needs to be optimized and improved during use. Unlike conventional ordinary new energy batteries, the plug interface needs to be sealed during use.

[0005] The utility model patent with Chinese patent application number 202223326002.9 discloses a solid-state hydrogen storage tank, including a shell, an insulation layer, a hydrogen inlet, a hydrogen outlet, a solid-state hydrogen storage unit, a support plate, a high-voltage sealed power socket, and a high-voltage sealed temperature sensor socket. The support plate is provided with a bracket (support block or support ring) made of elastic material, which can provide sufficient clamping force for the solid-state hydrogen storage unit under different temperature conditions and fix it on the shell to maintain the stability of the equipment structure. The setting of the hydrogen inlet and the hydrogen outlet can enable the hydrogen to flow continuously during hydrogen storage and remove the reaction heat in time. By adjusting the hydrogen flow rate and cooperating with the external hydrogen cooling circulation equipment, the balance between the reaction heat release and the heat removal can be maintained, and the operating temperature can be maintained accurately and stably. The solid-state hydrogen storage unit is provided with a hydrogen flow channel that runs through it, which can effectively increase the hydrogen diffusion rate, thereby increasing the hydrogen storage and release speed of the solid-state hydrogen storage tank and improving the operating efficiency. The technical solution proposed in the above utility model does not make any improvements or innovations on the gas outlet of the solid-state hydrogen storage tank. In actual use, there will still be technical problems such as hydrogen leakage during the hydrogen storage tank's intake or discharge process. Utility Model Content

[0008] Furthermore, the plug interface is exposed on the upper top surface of the hydrogen storage tank.

[0009] Furthermore, the plug interface includes a protective groove, a charging interface arranged in the protective groove, and a charging and discharging interface arranged in the protective groove, and a sealing structure is arranged in the protective groove.

[0010] Furthermore, the sealing structure includes a first annular groove and a second annular groove arranged on the inner side wall of the protective groove, a first sealing rubber ring is embedded in the first annular groove, and a second sealing rubber ring is embedded in the second annular groove.

[0014] Compared with the existing solid-state hydrogen storage tank, the utility model has the advantage that by providing a sealing structure, it can ensure that the hydrogen storage tank will not leak hydrogen during use, thereby further improving the safety of the solid-state hydrogen storage tank during use.
