DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 10 The present invention provides a technical solution: a small solid-state hydrogen storage device for a laboratory, comprising a shell 1, a universal wheel 11 for controlling the horizontal movement of the shell 1 is arranged below the shell 1, an opening is arranged on one side of the shell 1, and a rotating plate 3 is rotatably connected to the opening of the shell 1; The universal wheel 11 enables the shell 1 to be moved horizontally, which is convenient for transporting the solid-state hydrogen storage device in the laboratory, and the rotating structure of the rotating plate 3 and the shell 1 allows the rotating plate 3 to be rotated to the upper end to touch the ground, so that the small solid-state hydrogen storage device used in the laboratory can be rolled into the shell 1, avoiding the inconvenience of manpower in installing the solid-state hydrogen storage device in the shell 1 due to the lack of lifting equipment in the laboratory.

[0021] A gear 4, wherein the gear 4 is disposed in the housing 1, a placement seat 41 is disposed above the gear 4, and a solid hydrogen storage tank 5 is mounted on the placement seat 41; A locking assembly 6, the locking assembly 6 is located at both sides below the solid-state hydrogen storage tank 5, and the locking assembly 6 includes a clamping ring 64 for clamping and fixing the solid-state hydrogen storage tank 5; After the solid-state hydrogen storage device 5 is moved into the shell 1, the solid-state hydrogen storage tank 5 is vertically placed on the placement seat 41 to pre-fix the solid-state hydrogen storage tank 5, and then the clamp ring 64 is driven to retract inward through the locking assembly 6, so as to stably fix the solid-state hydrogen storage tank 5 in the shell 1, thereby preventing the solid-state hydrogen storage tank 5 from remaining stable when the shell 1 is moved, and preventing the solid-state hydrogen storage tank 5 from tipping over and causing damage to its function.

[0022] The rack 7 is arranged at a lower side of the housing 1 , and the rack 7 controls the locking assembly 6 to clamp and fix the solid hydrogen storage tank 5 .

[0023] The locking assembly 6 is controlled by the sliding structure of the rack 7 to clamp and release the solid hydrogen storage tank 5 so that the solid hydrogen storage tank 5 can be quickly disassembled and installed in the housing 1 .

[0024] A handle 12 is fixedly connected to the outer wall of the shell 1 on one side away from the rotating plate 3, and a slide groove 13 is fixedly connected to the upper and lower sides of the shell 1 respectively. An observation glass 2 is slidably connected in the slide groove 13, one end of the observation glass 2 abuts against the inner wall of the shell 1, and the other end of the observation glass 2 is rotatably connected to the inner wall of the rotating plate 3.

[0025] The structure of the handle 12 makes it convenient for laboratory personnel to push the shell 1 to move horizontally, and the structure of the observation glass 2 makes it convenient for laboratory personnel to observe the status of the solid-state hydrogen storage tank 5. When the rotating plate 3 rotates to touch the ground, the observation glass 2 can slide out of the slide groove 13, so that the laboratory personnel can install the solid-state hydrogen storage tank 5 after the solid-state hydrogen storage tank 5 rolls into the shell 1 through the rotating plate 3.

[0026] A rotating shaft 32 is provided below the rotating plate 3 , and the rotating plate 3 is rotatably connected to the shell 1 via the rotating shaft 32 . A sealing gasket 31 is provided on the top of the rotating plate 3 , and the rotating plate 3 is sealedly connected to the upper inner wall of the shell 1 via the sealing gasket 31 .

[0027] The rotating plate 3 rotates with the shell 1 through the structure of the rotating shaft 32, so that after the rotating plate 3 rotates to touch the ground, the upper end of the rotating plate 3 extends into the shell 1, which is convenient for the solid hydrogen storage tank 5 to be transported into the shell 1. The structure of the sealing gasket 31 ensures the airtightness of the shell 1 while preventing the rotating plate 3 from colliding with the top inner wall of the shell 1 during the rotation and closing process to cause damage.

[0028] There are several gears 4, which are evenly distributed horizontally at the bottom of the shell 1, and two adjacent gears 4 are meshed for transmission. The bottom of the gear 4 is rotatably connected to the bottom inner wall of the shell 1 through an axis, and the placement seat 41 is fixedly connected to the top of the gear 4. The placement seat 41 and the gear 4 rotate through the axis, the inner side of the placement seat 41 is set to be circular, and the outer wall of the placement seat 41 is set to be protruding at both ends.

[0029] The bottom of the solid-state hydrogen storage tank 5 is fixedly connected with a base 52 , and the base 52 is vertically inserted into the placement seat 41 . The base 52 is pre-fixed with the placement seat 41 , and a positioning ring 51 is fixedly connected to the side wall of the solid-state hydrogen storage tank 5 above the base 52 .

[0030] The structure of several gears 4 and the placement seat 41 facilitates the installation of several groups of solid hydrogen storage tanks 5. The circular structure inside the placement seat 41 facilitates the vertical insertion of the base 52 into the placement seat 41, so that the placement seat 41 can pre-fix the solid hydrogen storage tank 5 by clamping the base 52.

[0031] The inner side of the locking assembly 6 is slidably connected with a push plate 61, and the push plate 61 abuts against the outer wall of the placement seat 41. The outer side of the push plate 61 is fixedly connected with a slide column 62. The outer end of the slide column 62 is arranged in a slot in the locking assembly 6. The slide column 62 is slidably connected to the slot of the locking assembly 6. A first spring 63 is arranged at the end of the slide column 62, one end of the first spring 63 is fixedly connected to the slide column 62, and the other end of the first spring 63 is fixedly connected to the inner wall of the slot of the locking assembly 6.

[0032] Since the two ends of the placement seat 41 are set in a protrusion shape, when the protrusion of the placement seat 41 abuts against the abutment plate 61, the abutment plate 61 is pushed to both sides, causing the abutment plate 61 to slide in the direction of the locking assembly 6, that is, the sliding column 62 shrinks into the locking assembly 6 and compresses the first spring 63. When the placement seat 41 rotates, the protrusions on both sides of the placement seat 41 and the abutment plate 61 are deflected, and under the elastic force of the first spring 63, the abutment plate 61 is pushed to slide inward until the abutment plate 61 abuts against the placement seat 41 again.

[0033] A clamp ring 64 is fixedly installed above the abutment plate 61 . The clamp ring 64 is in contact with the outer wall of the positioning ring 51 . An anti-skid pad 65 is provided on the inner wall of the clamp ring 64 . The clamp ring 64 is clamped and fixed to the positioning ring 51 via the anti-skid pad 65 .

[0034] As the abutment plate 61 slides inward, it drives the clamping ring 64 to slide horizontally inward, so that the clamping ring 64 clamps the outer wall of the positioning ring 51, and the structure of the anti-slip pad 65 prevents the clamping ring 64 from loosening during the process of clamping the positioning ring 51, causing the positioning ring 51 to rotate inside the clamping ring 64.

[0035] The outer walls on both sides of the clamp ring 64 are set as bevels, and symmetrically distributed locking rods 42 are fixedly connected to the upper part of both sides of the gear 4. During the rotation of the gear 4, the locking rods 42 rotate along the bevels of the clamp ring 64 and abut against the outer wall of the clamp ring 64.

[0036] As the placement seat 41 rotates, the gear 4 rotates synchronously with the placement seat 41, so that after the protrusion of the placement seat 41 slides out from the inner side of the support plate 61, the clamping ring 64 abuts against the outer wall of the positioning ring 51. At this time, the gear 4 and the placement seat 41 are still rotating, so that the locking rod 42 slides toward the hypotenuse direction of the clamping ring 64 until the locking rod 42 abuts against the outer wall of the clamping ring 64, thereby preventing the clamping ring 64 from loosening during the process of clamping the positioning ring 51.

[0037] The rack 7 is arranged at the lower side close to the rotating plate 3, and the rack 7 is meshed with the gear 4 close to the rotating plate 3 for transmission. The rack 7 is horizontally slidably connected to the bottom inner wall of the shell 1, and a thread groove 73 is arranged in the middle of the rack 7. A rotating rod 8 is arranged at a position of the shell 1 corresponding to the thread groove 73, and the rotating rod 8 passes through the inner wall of the shell 1. The rotating rod 8 is rotatably connected to the inner wall of the shell 1, and a screw rod 81 is fixedly connected to the inner side of the rotating rod 8, and the screw rod 81 extends into the thread groove 73, and the screw rod 81 is threadedly connected to the thread groove 73.

[0038] By rotating the structure of the rotating rod 8, the screw rod 81 is rotated. Since the threaded groove 73 is threadedly connected to the screw rod 81, and the inner wall at the bottom of the shell 1 limits the rotation of the rack 7, the rack 7 slides toward the observation glass 2, causing the gear 4 close to the rack 7 to rotate, and all the gears 4 rotate synchronously.

[0039] A limiting frame 71 is fixedly connected above the rack 7, and a limiting groove 72 is provided on the side of the limiting frame 71 facing the rotating plate 3. The limiting groove 72 is viewed horizontally from the limiting frame 71. A fixed plate 33 is fixedly connected to the lower inner side of the rotating plate 3. The fixed plate 33 is located in the lower middle part of the rotating plate 3. The limiting groove 72 is parallel to the fixed plate 33. The limiting groove 72 is stuck on the outer side of the fixed plate 33 during the sliding process of the rack 7.

[0040] Before fixing the solid-state hydrogen storage tank 5, the rotating plate 3 is first rotated to close with the shell 1. During the process of driving the rack 7 to move, the limit frame 71 moves synchronously until the limit groove 72 in the limit frame 71 slides to the outside of the fixed plate 33, thereby restricting the rotation of the fixed plate 33 to prevent the rotating plate 3 from automatically opening during the movement of the shell 1. At the same time, when the solid-state hydrogen storage tank 5 needs to be taken out, that is, when the rotating plate 3 needs to be opened, the locking assembly 6 will synchronously release the solid-state hydrogen storage tank 5, thereby facilitating the installation and disassembly of the solid-state hydrogen storage tank 5.

[0041] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
