In the middle of the protective box 102, there is a hydrogen placement rack 200 for preventing hydrogen in the hydrogen storage tank 100. The upper and lower surfaces of the hydrogen placement rack 200 are provided with breathable grilles 201 for facilitating the fixed installation of the hydrogen placement rack 200. In the middle of the hydrogen placement rack 200, there is a hydrogen storage tank 100 for storing hydrogen. A number of positioning rings 300 for stably fixing the hydrogen storage tank 100 are evenly arranged on the surface of the hydrogen storage tank 100. At the four corners of the positioning ring 300, there are main positioning rods 301 for fixing the positioning ring 300 to the four corners of the inner wall of the hydrogen placement rack 200. The main positioning rods 301 adopting a four-corner design method can improve the stability of the positioning ring 300 for the hydrogen storage tank 100. On both sides of the positioning ring 300, there are secondary positioning rods 302 for fixing the positioning ring 300 to the inner wall of the hydrogen placement rack 200. The secondary positioning rods 302 are used to improve and reinforce the stability of the main positioning rods 301. On the front of the hydrogen placement rack 200, there is an opening and closing cover plate 202 for opening or closing the hydrogen placement rack 200. The opening and closing cover plate 202 and the front of the hydrogen placement rack 200 can be fixedly connected by using angle irons and bolts or movably connected by using hinges. On both sides of the middle of the opening and closing cover plate 202, there are fixing plates 103 for preventing the opening and closing cover plate 202 and the hydrogen placement rack 200 from falling. On one side of the upper end of the fixing plate 103, there is a first fixing block 104 for fixing the upper end of the fixing plate 103. On one side of the lower end of the fixing plate 103, there is a second fixing block 105 for fixing the lower end of the fixing plate 103.

[0024] During use, remove the fixing bolts 107 at both ends of the fixing plate 103 to separate the fixing plate 103 from the first fixing block 104 and the second fixing block 105. Open the opening and closing cover plate 202 and place the hydrogen storage tank 100 into the positioning ring 300 inside the hydrogen placement rack 200. Stabilize the hydrogen storage tank 100 through the positioning ring 300, stabilize the positioning ring 300 and the hydrogen storage tank 100 through the main positioning rods 301 at the four corners, protect the bottom of the hydrogen storage tank 100 through the buffer groove 207 and the buffer sponge 208, provide double protection for the hydrogen storage tank 100 through the hydrogen placement rack 200 and the buffer pads 205, and protect the hydrogen placement rack 200 through the protective box 102. Thus, when the mobile trolley 101 transports the hydrogen storage tank 100 and a collision occurs, it can effectively slow down the protection of the hydrogen storage tank 100 inside the hydrogen placement rack 200 and avoid damage to the hydrogen storage tank 100.
