Description

Technical Field

[0001] This utility model relates to the field of special gas holders, and in particular to an automatic sealing device and a special gas holder for gas leakage. Background Technology

[0002] A special gas holder is a device specifically designed for storing hydrogen. Its main functions are explosion-proof and leak-proof. The special gas holder uses explosion-proof copper powder composite material, which has excellent explosion-proof performance. When hydrogen is stored in the special gas holder, it can play a protective role in the event of a leak, preventing the leak from spreading and reducing the risk of an accident. The design and manufacture of special gas holders take into account the special properties of these gases to ensure safety and stability during use.

[0003] Special gas cabinets are usually equipped with heat dissipation mechanisms to ensure the safety and stability of gas storage and use. The purpose of the heat dissipation mechanism is to quickly dissipate the heat generated inside the special gas cabinet to prevent the gas storage container from overheating, thereby ensuring the stability of gas storage and use. The heat dissipation mechanism requires heat exchange between the cabinet and the outside environment to achieve the heat dissipation effect of the cabinet.

[0004] In existing technologies, ventilation holes are often provided on the surface of the cabinet to dissipate heat from the inside of the cabinet in conjunction with a heat dissipation mechanism. However, when a special gas inside the cabinet leaks, the leaked gas will escape to the outside through the ventilation holes on the surface of the cabinet, which will have a certain impact on the environment and the staff.

[0005] Currently, no effective solution has been proposed for the problems existing in related technologies, such as the leakage of special gases inside the cabinet, which then escapes to the outside through the heat dissipation holes on the surface of the cabinet. Utility Model Content

[0057] Example 1

[0058] An illustrative embodiment of this utility model, such as Figure 1As shown, an automatic sealing device for gas leakage includes a slide rail component 100, a first sealing component 200, a lifting component 300, a second sealing component 400, and a control component 500. The gas holder includes a slide rail component 100 mounted on the cabinet for mounting components; a first sealing component 200 slidably connected to the slide rail component 100 for sealing the ventilation holes in case of gas leakage; a lifting component 300 mounted on the cabinet and connected to the first sealing component 200 for lifting the first sealing component 200; a second sealing component 400 mounted at the ventilation holes of the cabinet and surrounding the ventilation holes for sealing the gap between the first sealing component 200 and the cabinet wall at the ventilation holes when the first sealing component 200 seals the ventilation holes; and a control component 500 mounted on the cabinet and connected to the slide rail component 100, the lifting component 300, and the second sealing component 400 for controlling the slide rail component 100, the lifting component 300, and the second sealing component 400.

[0059] like Figure 2 and Figure 3 As shown, the slide rail component 100 includes two slide rail components 110 and two blocking components 120. The two slide rail components 110 are disposed on the cabinet of the special gas cabinet and located on both sides of the heat dissipation hole, respectively, for sliding connection of the first sealing component 200; the two blocking components 120 are respectively disposed on the corresponding slide rail component 110 and are telescopically connected to the slide rail component 110, for supporting the first sealing component 200 when it is above the heat dissipation hole.

[0060] Specifically, the two slide rail components 110 are installed on the special gas cabinet by means of welding, riveting or bolting, and are located at the heat dissipation holes of the special gas cabinet. The two slide rail components 110 are located on both sides of the length direction of the heat dissipation holes. In addition, the length direction of the slide rail components 110 is set in the vertical direction.

[0061] In some embodiments, the slide rail 110 includes, but is not limited to, a linear guide rail.

[0062] It should be noted that each slide rail 110 has a slot at its top, through which the blocking member 120 passes, thereby enabling the blocking member 120 to extend and retract within the slide rail 110.

[0063] Specifically, the blocking member 120 is slidably connected to the slide rail member 110. The blocking member 120 can extend and retract along the groove in the slide rail member 110. That is, when the first sealing member 200 seals the heat dissipation holes of the special gas cabinet, the blocking member 120 is in a retracted state; when the first sealing member 200 does not seal the heat dissipation holes of the special gas cabinet, the blocking member 120 extends through the groove into the interior of the slide rail member 110, thereby providing support for the first sealing member 200.

[0070] In some of these embodiments, the first seal 210 includes, but is not limited to, a sealing plate.

[0071] Specifically, the filter element 220 is detachably connected to the first seal 210 by means of threaded connection or other means. That is, the first seal 210 has several threaded holes, and the filter element 220 can be installed with the threaded holes.

[0072] In some of these embodiments, the filter element 220 includes, but is not limited to, a filter cartridge.

[0073] It should be noted that the number of filter elements 220 can be set according to actual needs, and no further restrictions are imposed here.

[0074] Furthermore, the first sealing component 200 also includes a lug 230. The lug 230 is disposed on the top of the first sealing component 210 and is used for connecting components in the lifting component 300.

[0075] Specifically, there are two hanging ears 230. The two hanging ears 230 are installed at the top corner of the first seal 210 by means of welding, riveting or bolting. That is, the hanging ears 230 can be passed through by the components in the lifting component 300, thereby realizing the connection between the first seal 210 and the lifting component 300.

[0076] It should be noted that the number of ear loops 230 can also be 1, 3, etc., that is, the number of ear loops 230 can be set according to actual needs, and no further restrictions are imposed here.

[0077] like Figure 2 and Figure 4 As shown, the lifting component 300 includes a lifting drive component 310, two transmission connectors 320, two winding rollers 330, and two lifting ropes 340. The lifting drive component 310 is mounted on the special gas holder and connected to the control component 500. The two transmission connectors 320 are respectively connected to both ends of the output shaft of the lifting drive component 310, allowing unidirectional rotation under the action of the lifting drive component 310. The two winding rollers 330 are respectively connected to their corresponding transmission connectors 320, allowing rotation under the action of the transmission connectors 320. The first ends of the two lifting ropes 340 are respectively connected to their corresponding winding rollers 330, and the second ends of the two lifting ropes 340 are respectively connected to both sides of the first sealing component 200, allowing the first sealing component 200 to rise.

[0078] Specifically, the lifting drive component 310 is installed on the special gas cabinet by means of welding, riveting or bolting, and the lifting drive component 310 is connected to the control component 500 by means of wired connection.

[0079] In some of these embodiments, the lifting drive 310 includes, but is not limited to, a rotary motor.

[0080] Specifically, the two transmission connectors 320 are connected to the two ends of the output shaft of the lifting drive 310 along the length direction by means of welding, riveting or bolting, and are coaxially connected with the output shaft of the lifting drive 310. It should be noted that the transmission connectors 320 can rotate in the forward direction under the drive of the lifting drive 310, and can rotate freely in the reverse direction when the lifting drive 310 is not working.

[0081] In some of these embodiments, the transmission connection 320 includes, but is not limited to, a one-way bearing.

[0082] Specifically, the two winding rollers 330 are respectively sleeved on the corresponding transmission connectors 320, and are coaxially connected to the corresponding transmission connectors 320 by welding, riveting or bolting, and the winding rollers 330 can rotate with the transmission connectors 320.

[0083] In some embodiments, the winding roller 330 includes, but is not limited to, a hollow circular roller.

[0084] Specifically, the first ends of the two lifting ropes 340 are connected to the corresponding winding rollers 330 by means of tying or other methods, and the second ends of the two lifting ropes 340 pass through the corresponding hanging ears 230 on the first seal 210 and are connected to the first seal 210 by means of tying or other methods.

[0085] In some of these embodiments, the lifting rope 340 includes, but is not limited to, a steel cable.

[0086] It should be noted that the first end and the second end of the lifting rope 340 are the two ends of its length direction, respectively.

[0087] like Figure 2 As shown, the second sealing component 400 includes a second sealing element 410 and an inflation element 420. The second sealing element 410 is disposed on the cabinet of the special gas cabinet and is arranged circumferentially around the heat dissipation holes, used to seal the gap between the first sealing component 200 and the cabinet wall at the heat dissipation holes when the first sealing component 200 closes the heat dissipation holes; the inflation element 420 is disposed on the cabinet of the special gas cabinet and communicates with the second sealing element 410, and the inflation element 420 is connected to the control component 500, used to inflate the second sealing element 410, causing it to expand.

[0088] Specifically, the second sealing element 410 is installed on the special gas cabinet by means of bonding, riveting or bolting, and the second sealing element 410 can expand under the action of the inflation element 420, thereby sealing the gap between the first sealing element 210 and the special gas cabinet.

[0089] In some of these embodiments, the second seal 410 includes, but is not limited to, an airbag.

[0090] It should be noted that the second sealing element 410 includes an inflation port, a deflation port, and a wooden plug. The inflation port is located on the second sealing element 410 and communicates with the inflation element 420, thereby enabling the inflation of the second sealing element 410. The deflation port is located on the second sealing element 410 and is used for deflation of the second sealing element 410. The wooden plug is screwed onto the deflation port to seal it.

[0091] Specifically, the inflation component 420 is fixed to the special gas cabinet by welding, riveting or bolting, and is connected to the control component 500 by wired connection, etc. The inflation component 420 is connected to the inflation port of the second seal 410 through an air pipe, thereby allowing the second seal 410 to expand.

[0092] In some of these embodiments, the inflation component 420 includes, but is not limited to, an air pump.

[0093] like Figure 5 As shown, the control unit 500 includes a communication component 510 and a control component 520. The communication component 510 is installed in the special gas cabinet and connected to an external remote control device for receiving and transmitting signals. The control component 520 is installed in the special gas cabinet and is connected to the communication component 510, the slide rail component 100, the first sealing component 200, the lifting component 300, and the second sealing component 400, respectively, for controlling the slide rail component 100, the lifting component 300, and the second sealing component 400.

[0094] Specifically, the communication component 510 is installed on the special gas cabinet by means of welding, riveting or bolting, and is connected to external remote control equipment by means of wireless connection.

[0095] In some embodiments, the communication device 510 includes, but is not limited to, a Bluetooth sensor, a WiFi sensor, and a ZigBee sensor.

[0096] Specifically, the control component 520 is installed on the special gas cabinet by welding, riveting or bolting, and is connected to the communication component 510, the telescopic drive component 130, the filter component 220, the lifting drive component 310 and the inflation component 420 by wired connection, etc., to control the start and stop of the telescopic drive component 130, the filter component 220, the lifting drive component 310 and the inflation component 420.

[0097] In some of these embodiments, the controller 520 includes, but is not limited to, an MCU, a Raspberry Pi, or a microcontroller.

[0098] The usage method of this embodiment is as follows:

[0099] In actual operation, when a leak occurs inside the special gas cabinet, the control unit 520 activates the telescopic drive unit 130, which drives the blocking unit 120 to extend and retract, thereby causing the blocking unit 120 to disengage from the slide rail 110 along the slot, and then causing the first sealing unit 210 to fall quickly along the slide rail 110 (it should be noted that since the winding roller 330 is connected to the output shaft of the lifting drive unit 310 through the transmission connector 320, and the transmission connector 320 is a one-way bearing, the winding roller 330 can rotate freely in the opposite direction).

[0100] When the first seal 210 completely covers the heat dissipation hole, the control unit 520 activates the inflation unit 420, which causes the second seal 410 to expand, thereby allowing the second seal 410 to seal the gap between the first seal 210 and the side wall of the special gas cabinet.

[0101] When there is no gas leakage inside the special gas cabinet, the control unit 520 starts the lifting drive unit 310. The lifting drive unit 310 drives the winding roller unit 330 to rotate through the transmission connector 320. That is, the lifting rope unit 340 can drive the first sealing unit 210 to rise, thereby opening the heat dissipation hole.

[0102] The advantage of this embodiment is that by connecting the first sealing component with the lifting component and the slide rail component, the first sealing component can be quickly lowered in the event of gas leakage in the special gas cabinet, thereby achieving rapid sealing of the heat dissipation holes of the special gas cabinet; by setting a second sealing component at the heat dissipation holes of the special gas cabinet, the second sealing component can seal the gap between the first sealing component and the side wall of the special gas cabinet, further improving the sealing effect, thereby preventing leaked gas inside the special gas cabinet from overflowing through the heat dissipation holes.

[0106] The special gas holder also includes a leak detection element 610. The leak detection element 610 is installed inside the special gas holder body 600 and is used to detect the gas pressure inside the special gas holder body 600.

[0107] Specifically, the leakage detection component 610 is fixed inside the special gas holder cabinet 600 by means of welding, riveting or bolting, and the leakage detection component 610 can detect the internal pressure changes inside the special gas holder cabinet 600 to detect the internal pressure changes inside the special gas holder cabinet 600.

[0108] In some of these embodiments, the leak detection device includes, but is not limited to, a pressure sensor.

[0109] The usage method and advantages of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
