[0044] Please refer to Figures 1-12, a special gas cabinet system with a self-sealing mechanism provided in this embodiment includes a cabinet body 1 and a tank body 11 arranged in the cabinet body 1.

A connecting pipe 12 is connected in the cabinet body 1, an air outlet pipe 13 is connected to the tank body 11, and a control valve for controlling the opening and closing of the air outlet pipe 13 is arranged on the tank body 11. The setting of the control valve is also an existing structure and will not be elaborated here. An installation frame 14 is fixedly connected in the cabinet body 1, and a sealing component is arranged in the installation frame 14; a limiting mechanism is also included, which is arranged in the cabinet body 1; during installation, the limiting mechanism moves to limit and fix the tank body 11, and the sealing component is triggered to move by a triggering mechanism to self-seal and wrap the air outlet pipe 13. The sealing component drives the connecting pipe 12 to move through the triggering mechanism and contacts and communicates with the air outlet pipe 13 on the tank body 11, and then drives the sealing component to wrap and seal the connection part of the two. Its sealing effect is good and its installation is simpler and more convenient; during disassembly, the limiting mechanism moves upward to reset, the air outlet pipe 13 is driven to close through a transmission mechanism, and then the sealing component is triggered to unlock through the triggering mechanism to realize the separation of the gas storage tank and the connecting pipe 12. By closing the air outlet pipe 13 first, the hydrogen remaining inside the tank body 11 can be effectively prevented from overflowing, improving the safety during the disassembly of the sealing component and having strong practicability.

[0045] In the further embodiment provided by the present invention, the sealing component includes two convex blocks 21 slidably connected in the installation frame 14 and two rectangular blocks 22; both ends of the two rectangular blocks 22 are rotatably connected to both sides of the two convex blocks 21 through rotating plates 23.

Arc-shaped plates 24 are fixedly connected to both the two convex blocks 21 and the two rectangular blocks 22. The same sealing ring 25 is fixedly connected inside the four arc-shaped plates 24. The four arc-shaped plates 24 can form a circular ring. One side of the sealing ring 25 is fixedly connected with a rubber ring 26. The rubber ring 26 has good sealing performance and stretchability; one end of the air outlet pipe 13 is connected with a first interface pipe 27, and the rubber ring 26 is fixedly connected to the outside of the first interface pipe 27.

[0046] Furthermore, the guiding unit includes moving blocks 31 fixedly connected to the two convex blocks 21; two track grooves 32 are opened in the installation frame 14. The track groove 32 is composed of an inclined groove, two horizontal grooves and a vertical groove. The part of the horizontal groove close to the connecting pipe 12 is set as a wave crest shape. Its specific shape can be referred to in the attached Figure 7 description. Both of the two moving blocks 31 are slidably connected in the corresponding track grooves 32 through track rods 33. By setting the track grooves 32 and the track rods 33, the movement track of the moving blocks 31 can be controlled. A limiting member for limiting the movement of the moving blocks 31 is also arranged in the installation frame 14.

[0047] Furthermore, the limiting member includes a blocking block 4 elastically and slidably connected in the mounting frame 14. A groove for the blocking block 4 to slide is provided on the mounting frame 14. The blocking block 4 is arranged at the vertical groove of the track groove 32, and the moving block 31 can be restricted by the blocking block 4.

[0048] In an embodiment further provided by the present invention, the limiting mechanism includes an electric telescopic rod 51 fixedly connected in the cabinet body 1 and a positioning frame 52. The electric telescopic rod 51 is connected to an external power supply and a control switch. After the electric telescopic rod 51 is powered off, it maintains the state before power-off. The positioning frame 52 can limit the can body 11. The bottom end of the electric telescopic rod 51 is fixedly connected with a limiting frame 53. By driving the limiting frame 53 to move downward through the operation of the electric telescopic rod 51, the can body 11 in the positioning frame 52 can be further fixed and limited.

[0049] In the embodiment provided by the present invention, the triggering mechanism includes two trigger blocks 61 elastically and slidably connected in the mounting frame 14. The two trigger blocks 61 are respectively arranged on both sides of the communicating pipe 12. Wedge-shaped through grooves 62 are opened inside the two trigger blocks 61. The wedge-shaped through grooves 62 penetrate through the trigger blocks 61. The two trigger blocks 61 are fixedly connected with the same fixed disk 63; the fixed disk 63 is fixed on the communicating pipe 12. A plurality of limiting grooves 64 are opened on the fixed disk 63. The plurality of limiting grooves 64 are distributed in an annular array with the communicating pipe 12 as the center. Limiting rods 65 are fixedly connected to each arc-shaped plate 24. Each limiting rod 65 is slidably connected in the corresponding limiting groove 64; A fixed rod 66 is fixedly connected between the mounting frame 14 and the cabinet body 1. A translation plate 67 is slidably connected to the fixed rod 66. Two wedge-shaped rods 68 and two L-shaped support plates 69 are fixedly connected to the translation plate 67. The wedge-shaped rods 68 will be clamped and matched with the wedge-shaped through grooves 62 during the movement stroke. A support spring 610 is fixedly connected between the translation plate 67 and the mounting frame 14. Two L-shaped pulling plates 611 are fixedly connected to the limiting frame 53. The L-shaped pulling plates 611 will contact the L-shaped support plates 69 during the movement stroke. The L-shaped support plates 69 and the L-shaped pulling plates 611 are both arranged in an L shape.

[0050] In a further solution provided by the present invention, one end of the air outlet pipe 13 is communicated with a second interface pipe 71. An elastic rubber ring 72 is arranged inside the second interface pipe 71. The elastic rubber ring 72 is fixed at one end of the second interface pipe 71. When the first interface pipe 27 on the communicating pipe 12 contacts the second interface pipe 71, the elastic rubber ring 72 can be extruded, so that the elastic rubber ring 72 deforms, facilitating the sealing of the gap between the first interface pipe 27 and the second interface pipe 71, and realizing the sealing between the connection of the first interface pipe 27 and the second interface pipe 71.

[0051] In a further solution provided by the present invention, an air connection component is provided on the mounting frame 14. The air connection component includes an air connection frame 81 fixedly connected to the mounting frame 14. A diversion pipe 82 is connected between the air connection frame 81 and the rubber ring 26. When leakage occurs at the connection of the first interface pipe 27 and the second interface pipe 71, the diversion pipe 82 can introduce the leaked hydrogen into the air connection frame 81 for storage. In addition, an exhaust pipe can be provided on the air connection frame 81 to introduce the hydrogen in the air connection frame 81 into the communication pipe 12 for conduction when necessary.

[0052] In a further solution provided by the present invention, the transmission mechanism includes a first toothed plate 91 slidably connected to the limiting frame 53. A vertical rod 92 is fixedly connected between the positioning frame 52 and the cabinet body 1. A cam 93 and a first bevel gear 94 are fixedly connected to the vertical rod 92; a rotating rod 95 is rotatably connected to the cabinet body 1. A second bevel gear 96 and a gear disk 97 are fixedly connected to the rotating rod 95. The first toothed plate 91 meshes with the gear disk 97 during its movement stroke. When the first toothed plate 91 contacts the gear disk 97 and triggers it to rotate one week, the first toothed plate 91 will separate from the gear disk 97. An incomplete helical gear 98 is fixedly connected to the switch valve rod of the tank body 11; an abutting frame 99 is connected to the cabinet body 1 through an elastic telescopic rod. A helical toothed plate 910 is elastically connected in the abutting frame 99. The helical toothed plate 910 meshes with the incomplete helical gear 98 during its movement stroke. The teeth of the incomplete helical gear 98 are composed of helical teeth. One side of the helical teeth is set as an inclined surface, and the other side is set as a flat surface. The helical toothed plate 910 is also composed of helical teeth, and its helical teeth are the same as those on the incomplete helical disk. When the flat side of the teeth of the helical toothed plate 910 contacts the flat side of the teeth of the incomplete helical gear 98 during the movement of the helical toothed plate 910, the movement of the helical toothed plate 910 will drive the incomplete helical gear 98 to rotate. On the contrary, when the inclined surface of the teeth of the helical toothed plate 910 contacts the inclined surface of the teeth of the incomplete helical gear 98 during the movement of the helical toothed plate 910, the helical toothed plate 910 will be squeezed into the interior of the abutting frame 99. An auxiliary component is also provided on the cabinet body 1.

[0053] In a further solution provided by the present invention, the auxiliary component includes an auxiliary rod 101 fixedly connected to the first toothed plate 91. A rectangular groove 102 is formed on the cabinet body 1. The auxiliary rod 101 is slidably connected in the rectangular groove 102. The rectangular groove 102 is composed of two inclined grooves and two vertical grooves. The inclined grooves and the vertical grooves are connected end to end in sequence. For its specific shape, please refer to the attached Figure 8 description. By providing the rectangular groove 102 and the auxiliary rod 101, the horizontal movement of the first toothed plate 91 can be controlled, so that it can intermittently contact the gear disk 97.

[0054] Working principle: During operation, the tank body 11 to be installed is pushed into the positioning frame 52 in the cabinet body 1, and the electric telescopic rod 51 in the cabinet body 1 is started. The extension of the electric telescopic rod 51 drives the limiting frame 53 to move downward to limit and fix the tank body 11 in the positioning frame 52. When the limiting frame 53 moves downward to the stroke of the tank body of the tank body 11, the L-shaped pull plate 611 connected to the limiting frame 53 moves synchronously, and the L-shaped pull plate 611 will contact the L-shaped support plate 69 during movement and pull the L-shaped support plate 69 to move downward synchronously. The downward movement of the L-shaped support plate 69 will drive the wedge-shaped rod 68 to move through the translation plate 67. The downward movement of the wedge-shaped rod 68 will enter the wedge-shaped through groove 62 inside the moving block 31 and limit the moving block 31. After the wedge-shaped rod 68 enters the wedge-shaped through groove 62, it will drive the moving block 31 to move. The spring connected between the moving block 31 and the installation frame 14 will be stretched, and the movement of the moving block 31 will drive the fixed disk 63 and the communication pipe 12 to move synchronously, so that the first interface pipe 27 on the communication pipe 12 abuts against the second interface pipe 71 at one end of the air outlet pipe 13 on the fixed tank body 11. When the two are in contact, the first interface pipe 27 will squeeze the elastic rubber ring 72 in the first interface pipe 27, so that the elastic rubber ring 72 deforms to seal the connection between the two. When the fixed disk 63 moves, it will drive the arc-shaped plate 24 to move synchronously through the limiting rod 65. When the arc-shaped plate 24 moves, it will drive the convex block 21 and the rectangular block 22 to move synchronously. When the convex block 21 moves, it will be affected by the track groove 32, so that the arc-shaped plate 24 connected to the convex block 21 changes its position. The change in its position mainly starts from moving away from the first interface pipe 27, and continues to move a certain distance while maintaining the state of moving away, and then approaches the first interface pipe 27. The movement of the convex block 21 can drive the arc-shaped plates 24 connected by the rectangular blocks 22 on both sides to move synchronously through the cooperation of the rotating plate 23. The movement of the arc-shaped plate 24 will stretch the connected sealing ring 25, so that the inner diameter of the sealing ring 25 becomes larger, facilitating the entry of the second interface pipe 71. When the arc-shaped plate 24 moves back and approaches the first interface pipe 27, at this time, the sealing ring 25 will be stuck on the second interface pipe 71 under the action of the arc-shaped plate 24, so as to achieve further wrapping and sealing. And when the moving block 31 moves, it will squeeze the blocking block 4, so that the blocking block 4 retracts into the groove inside the installation frame 14. It is not until the blocking block 4 moves downward that the blocking block 4 will block above the moving block 31 to limit the moving block 31;

[0055] When the tank body 11 needs to be replaced, the electric telescopic rod 51 is driven to drive the limit frame 53 to move upward. The limit frame 53 drives the L-shaped pull plate 611 to move synchronously, so as to reduce the pulling force on the L-shaped support plate 69. At this time, the restoring force of the support spring 610 compressed on the translation plate 67 is generated, so as to drive the translation plate 67 to drive the L-shaped support plate 69 to move synchronously. When the translation plate 67 moves upward, it will also drive the wedge-shaped rod 68 to move out of the wedge-shaped through groove 62 in the trigger block 61. During the process that the wedge-shaped rod 68 moves out of the wedge-shaped through groove 62 but does not disengage, the first toothed plate 91 connected to the limit frame 53 will move to the other side of the rectangular groove 102 under the action of the auxiliary rod 101 and move along with the upward movement of the limit frame 53. At this time, the first toothed plate 91 will rotate with the gear disc 97 on the rotating rod 95 and drive the rotating rod 95 to drive the second bevel gear 96 to rotate. The rotation of the second bevel gear 96 will be engaged with the first bevel gear 94 on the vertical rod 92, so as to drive the vertical rod 92 to rotate accordingly. The rotation of the vertical rod 92 will drive the cam 93 to rotate. The rotation of the cam 93 will gradually reduce the extrusion on the contact frame 99. The contact frame 99 will move under the action of the elastic telescopic rod. When the contact frame 99 moves, it drives the helical toothed plate 910 arranged inside it to move synchronously and contact with the incomplete helical gear 98 on the valve rod of the switch valve of the tank body 11. During the contact process, the helical toothed plate 910 drives the incomplete helical gear 98 to rotate, so that the switch valve is closed. Then the contact frame 99 is reset under the rotation of the cam 93. At this time, the inclined surface side of the tooth of the helical toothed plate 910 contacts the inclined surface side of the incomplete helical gear 98, so the helical toothed plate 910 will retract into the contact frame 99 until it passes through the incomplete helical gear 98 and then resets under the action of the spring;

[0056] After the switch valve on the tank body 11 is closed, the air outlet pipe 13 will not discharge air at this time, and the wedge-shaped rod 68 will completely enter the wedge-shaped through groove 62 of the trigger block 61 and gradually separate from the wedge-shaped through groove 62. After separation, the abutting force of the wedge-shaped rod 68 on the trigger block 61 disappears. At this time, the restoring force of the spring connected between the trigger block 61 and the cabinet body 1 pulls the trigger block 61 to reset. The trigger block 61 drives the first interface pipe 27 to separate from the second interface pipe 71, and the arc-shaped plate 24 connected to the convex block 21 will spread again under the influence of the track groove 32, so that the expansion of the sealing ring 25 can be detached from the second interface pipe 71 conveniently.

[0057] Only some exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
