[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 and Figure 2 This utility model provides a solid hydrogen storage device with high sealing performance, including a placement body 1, a placement groove on the side of the placement body 1, a solid hydrogen storage tank 2 placed in the placement groove of the placement body 1, a fixing mechanism 3 movably connected inside the placement body 1, a buffer mechanism 4 fixedly connected to the bottom of the placement body 1, and six placement grooves in the placement body 1 arranged in two rows and three columns, with the same spacing between the placement grooves in the placement body 1.

[0023] In this embodiment of the application, the placement body 1 is provided with six placement slots, each of which contains a solid hydrogen storage tank 2. Multiple solid hydrogen storage tanks 2 can be transported at one time. The six placement slots are arranged in two rows and three columns, and the spacing between the placement slots is the same, so that the force is more uniform.

[0024] Reference Figure 3 and Figure 4The fixing mechanism 3 includes an adjustable first handwheel 301. A first bidirectional screw 302 is fixedly connected to the bottom end of the first handwheel 301. An upper fixing plate 303 and a lower fixing plate 304 are threadedly connected to the side of the first bidirectional screw 302. The upper fixing plate 303 and the lower fixing plate 304 are mirror-symmetrical and can move synchronously in opposite directions. An output gear 305 is fixedly connected to the top end of the side of the first bidirectional screw 302. A synchronous belt 306 meshes with the side of the output gear 305. The synchronous belt 306 is located away from the output gear. One side of wheel 305 is engaged with a synchronous wheel 307. The inside of the synchronous wheel 307 is fixedly connected to a second bidirectional screw 308. The top of the second bidirectional screw 308 is fixedly connected to a second handwheel 309. The side of the second bidirectional screw 308 is threadedly connected to the inside of the upper fixed plate 303 and the lower fixed plate 304. The upper fixed plate 303 and the lower fixed plate 304 are mirror symmetrical about the center plane of the two rows of placement slots in the placement body 1. The threaded grooves in the upper fixed plate 303 and the lower fixed plate 304 are synchronously mirror symmetrical with the upper fixed plate 303 and the lower fixed plate 304.

[0025] In this embodiment, the side of the first bidirectional screw 302 is provided with a mirrored threaded groove. At this time, the upper fixing plate 303 and the lower fixing plate 304 will only move towards each other or in opposite directions. When the upper fixing plate 303 moves upward, it can fix the upper solid hydrogen storage tank 2. When the lower fixing plate 304 moves downward, it can fix the lower solid hydrogen storage tank 2. Therefore, this application can simultaneously perform the fixing work of six solid hydrogen storage tanks 2. After the first handwheel 301 is driven by the output gear 305, the synchronous wheel 307, and the synchronous wheel 309, the first handwheel 301 and the second handwheel 309 can rotate synchronously. Therefore, two hands or two people can simultaneously use the first handwheel 301 and the second handwheel 309 to adjust, apply more force, and thus ensure the stability of the fixation.

[0026] Reference Figure 1 and Figure 5 The buffer mechanism 4 includes a connecting rod 401 fixedly connected to the bottom end of the placement body 1. The bottom end of the connecting rod 401 is fixedly connected to a limiting plate 402. The side of the limiting plate 402 is movably connected to a limiting sleeve 403. The bottom end of the limiting sleeve 403 is fixedly connected to a placement plate 405. Both the connecting rod 401 and the side of the placement plate 405 are provided with buffer mounting 404. The top end of the buffer mounting 404 contacts the bottom end of the placement body 1, and the bottom end of the buffer mounting 404 contacts the top end of the placement plate 405.

[0027] In this embodiment, when the connecting rod 401 moves up and down within the limiting sleeve 403, it will compress the buffer mounting 404. When the buffer mounting 404 is compressed, it will automatically buffer the movement, thereby ensuring the stability of the main body 1 when it shakes and preventing hydrogen leakage.

[0028] The working principle of this utility model is as follows: When it is necessary to place the solid hydrogen storage tank 2 in the placement body 1, the first handwheel 301 is rotated. When the first handwheel 301 rotates, it drives the first bidirectional screw 302 to rotate. The side of the first bidirectional screw 302 is provided with a mirrored thread groove. At this time, the upper fixing plate 303 and the lower fixing plate 304 will only move towards each other or in opposite directions. This causes the upper fixing plate 303 and the lower fixing plate 304 to move towards each other. Therefore, the upper fixing plate 303 moves downward and away from the placement groove above the placement body 1, and the lower fixing plate 304 moves upward to the placement groove below the raw material placement body 1. At this time, the placement groove in the placement body 1 is in an empty state. The solid hydrogen storage tank 2 is placed into the placement groove of the placement body 1.

[0029] When the solid hydrogen storage tank 2 enters the placement slot of the placement body 1, the first handwheel 301 is rotated in the reverse direction. The first handwheel 301 rotates in the reverse direction, which drives the first bidirectional screw 302 to rotate in the reverse direction. When the first bidirectional screw 302 rotates in the reverse direction, the upper fixing plate 303 and the lower fixing plate 304 move in opposite directions. At this time, the upper fixing plate 303 moves upward to fix the upper solid hydrogen storage tank 2, and the lower fixing plate 304 moves downward to fix the lower solid hydrogen storage tank 2. The fixing of the solid hydrogen storage tank 2 can be carried out quickly.

[0030] After the solid hydrogen storage tank 2 is fixed, it can be transported. During transportation, when the road surface is bumpy, the placement body 1 will move the solid hydrogen storage tank 2 up and down. When the placement body 1 moves up and down, it will cause the connecting rod 401 to move up and down within the limiting sleeve 403. At this time, the placement body 1 will compress the buffer installation 404. When the buffer installation 404 is compressed, it will automatically buffer the movement, thus ensuring the stability of the placement body 1 when it shakes. After transportation, when removing the solid hydrogen storage tank 2, simply turn the first handwheel 301 again to make the upper fixing plate 303 and the lower fixing plate 304 move towards each other, automatically releasing the solid hydrogen storage tank 2, which can be quickly removed.

[0031] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
