[0037] The working principle of the solid-state hydrogen storage safety protection device is as follows: when it is needed to prevent hydrogen leakage of the solid-state hydrogen storage device 2 from causing danger, the adjusting ring 308 is first rotated to separate the rubber pad 309 from the screw rod 307, and then the bottom plate 302 is moved to drive the mounting plate 306, so that the mounting plate 306 drives the screw rod 307 to separate from the fixed plate 303 and the fixed hole 304; at this time, the bottom plate 302 can be taken out from the protection box 301; after the bottom plate 302 is removed, the solid-state hydrogen storage device 2 is placed on the bottom plate 302, and then the bottom plate 302 is placed into the protection box 301; at the same time, the screw rod 307 fixed on the mounting plate 306 needs to be inserted into the fixed hole 304; after the screw rod 307 is inserted into the fixed hole 304, the adjusting ring 308 is sleeved on the arc surface of the screw rod 307; finally, the screw rod 307 is rotated to drive the rubber pad 309 to abut against the upper surface of the fixed plate 303, so that the installation of the bottom plate 302 is completed; at this time, the solid-state hydrogen storage device 2 is placed in the protection box 301; when the solid-state hydrogen storage device 2 leaks hydrogen, the hydrogen detector 314 detects that there is hydrogen leakage, and then transmits a signal to the central processing system in the controller 1; the central processing system controls the fan 315 to start, so that the leaked hydrogen in the protection box 301 can be extracted; the extracted hydrogen enters the tank 312 through the communication pipe 311 for storage; when the hydrogen detector 314 does not detect hydrogen, the fan 315 is automatically powered off; personnel can regularly extract the hydrogen in the tank 312 for transportation; the one-way valve 305 installed on the outer wall of the communication pipe 311 can prevent the hydrogen from flowing back into the protection box 301 after entering the tank 312; in addition, the sealing ring 310 can block the small gap between the protection box 301 and the bottom plate 302, thereby improving the sealing performance between the protection box 301 and the bottom plate 302; finally, the rubber pad 309 can improve the friction force of the side of the adjusting ring 308 close to the fixed plate 303, so that the adjusting ring 308 can abut against the upper surface of the fixed plate 303 more stably.

[0038] When it is needed to use different sizes of solid-state hydrogen storage devices 2, the solid-state hydrogen storage device 2 is first placed on the bottom plate 302, and then the pressing rod 46 is rotated to separate from the screw rod 42, so that the limiting of the screw rod 42 is released; then the screw rod 42 is rotated to drive the ear plate 43, so that the two ear plates 43 move towards each other along the arc surface of the screw rod 42; the ear plate 43 drives the clamping plate 44; when the clamping plate 44 abuts against the side of the shell 21 of the solid-state hydrogen storage device 2 stably, the pressing rod 46 is rotated to abut against the arc surface of the screw rod 42, so that the clamping and limiting of the solid-state hydrogen storage device 2 are completed; the clamping plate 44 moves along the inner wall of the sliding hole 45, thereby improving the stability of the movement of the clamping plate 44.

[0039] The circuit and the control involved in the utility model are prior art, and will not be described in detail here.
