[0031] The hydrogen delivery situation can be detected by the provided flow meter 213 and temperature sensor 215. When in use, the hydrogen bottle 3 and the solenoid valve 212 are opened, and the hydrogen will enter the interior of the solid-state hydrogen storage container through the air supply pipe 1 and the connecting component 22. While transporting hydrogen, the hydrogen flow rate will be detected by the flow meter 213, and the pressure and temperature of the hydrogen inside the air supply pipe 1 will be monitored by the pressure sensor 214 and the temperature sensor 215. Then, the PLC control system of the solid-state hydrogen storage container is used to collect and analyze these data to determine whether the hydrogen filling process is completed, which is convenient and quick.

[0032] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0033] During use, the user connects the installation tube 2211 to the input end of the solid-state hydrogen storage container, opens the hydrogen bottle 3 and the solenoid valve 212, and the hydrogen will enter the interior of the solid-state hydrogen storage container through the air supply pipe 1 and the connecting component 22. While transporting hydrogen, the hydrogen flow rate will be detected by the flow meter 213, and the pressure sensor 214 and the temperature sensor 215 will monitor the pressure and temperature of the hydrogen inside the air supply pipe 1.

When the hydrogen storage is completed, the solenoid valve 212 is closed and waits for the subsequent hydrogen discharge operation signal. When the air supply pipe 1 needs to be disassembled to inspect and maintain the detection component 21, the pull rod 221 is pulled to drive the movable plate 223 to make the block 224 leave the outside of the air supply pipe 1 and the clamping ring 2213, and then the air supply pipe 1 can be pulled out. Separate from the mounting tube 2211 to inspect and maintain the detection assembly 21. After the inspection and maintenance of the air supply pipe 1 and the detection assembly 21 are completed, pick up the air supply pipe 1 and insert the cannula 2214 into the interior of the slot 2212. At this time, the snap ring 2213 will push the block 224 open. When the snap ring 2213 leaves the bottom surface of the block 224, the elastic force of the spring 222 will drive the movable plate 223 to reset the block 224 and fix the position of the air supply pipe 1 through the snap ring 2213, so that the cannula 2214 is located inside the slot 2212. At the same time, the adjusting screw 2210 can be rotated to drive the movable ring 228 to move the connecting ring 226 to the right through the connecting plate 227. Then the connecting ring 226 will drive the block 224 to move to the right and cling to the left side of the snap ring 2213, so that the cannula 2214 clings to the inner side of the slot 2212 to improve its sealing. Then it can continue to be used.
