[0002] A special gas cabinet is a device used for storing, distributing, and controlling gases. It typically consists of a sealed metal cabinet and internal components such as a gas storage container, pressure regulator, and valves. Special gas cabinets can be used to store various gases, such as oxygen, nitrogen, and hydrogen, and can distribute and control gases as needed. The main function of a special gas cabinet is to ensure the safe storage and use of gases.

[0003] Special gas cabinets are usually equipped with heat dissipation mechanisms to ensure the safety and stability of gas storage and use. In existing technologies, heat dissipation holes are often opened on the surface of the cabinet to dissipate heat from the inside of the cabinet in conjunction with the heat dissipation mechanism. However, when the special gas inside the cabinet leaks, the leaked gas will diffuse to the outside through the heat dissipation holes on the surface of the cabinet and the heat dissipation mechanism, which will have a certain impact on the environment and personnel, and is quite inconvenient.

[0013] Preferably, the cabinet is provided with a rotatable sealing door, and the sealing door is fitted with an observation window, which is made of transparent material.

[0014] This invention also provides a method for using a leak-proof special gas holder, including the following specific steps: Step 1: Initial preparation and cylinder placement. Open the sealed door of the cabinet, place the cylinder securely on the partition, and ensure that the top of the cylinder faces the fixed plate and the connecting pipe is connected to the cylinder's interface. Based on the characteristics of the gas inside the cylinder, select and install a filter plate that can effectively filter the leaked gas in the filter groove of the treatment plate. Step 2: The gas cylinder is fixed and a sealed space is established. Start the motor and drive the lead screw to rotate, which causes the positioning plate to move smoothly downward under the guidance of the slide rod. The positioning plate hugs and secures the neck of the gas cylinder through the sealing ring embedded inside. At the same time, the bellows fixed between the fixing plate and the positioning plate extends, together with the two to form a sealed space that completely covers the top of the gas cylinder. Step 3: System operation and status monitoring. After closing the sealed door, turn on the exhaust fan of the exhaust mechanism to force the air inside the cabinet into the filter box through the exhaust pipe and then discharge it, forming a stable airflow circulation to provide continuous heat dissipation for the gas cylinder and related components. Step 4: Automatic Leak Response and Emergency Handling. When a leak occurs at the top of the gas cylinder, the leaking gas accumulates and the pressure increases in the sealed space formed by the bellows. This pressure pushes the piston rod of the valve opening and closing assembly upward, thereby releasing the lock on the rack through mechanical linkage. Driven by the first compression spring, the rack instantly springs up. On the one hand, it drives the gear and valve rod to rotate, immediately opening the valve of the treatment pipe and guiding the leaking gas through the filter plate for purification before safe discharge. On the other hand, the springing rack will trigger the switch button of the warning assembly, activating the buzzer installed on the cabinet to issue an alarm to notify the staff to handle the situation. Step 5: Automatic cleaning and system maintenance. During daily use, each time the positioning plate moves up and down to fix or release the gas cylinder, the cleaning mechanism connected to it via the connecting rod will rise and fall synchronously. Under the action of the second compression spring, the cleaning plate in the mechanism always fits tightly against the surface of the filter screen on both sides of the cabinet, automatically scraping off the attached impurities, maintaining the air permeability and heat dissipation efficiency of the filter screen, and ensuring that the equipment is in the best working condition.

[0015] The technical effects and advantages of this invention are as follows: (1) The present invention utilizes the combination of an exhaust mechanism and a sealing and fixing mechanism. The exhaust mechanism can be used to heat the gas cylinder normally with the filter screen. The sealing and fixing mechanism can not only fix the gas cylinder inside the cabinet, but also automatically and promptly open the treatment pipe for filtering the leaked gas when a leak occurs at the top of the gas cylinder. At the same time, it can also trigger a buzzer to alarm and remind the staff. While ensuring heat dissipation performance, it improves the safety and reliability of the special gas cabinet during use and is easy to use. (2) The present invention utilizes a combination of a sealing and fixing mechanism and a cleaning mechanism. When the sealing and fixing mechanism uses a motor to drive the positioning plate to fix or release the gas cylinder, the filter screen can be cleaned once. The elastic force of the second compression spring ensures that the cleaning plate and the filter screen are in full contact, effectively scraping away accumulated dust and fiber impurities, avoiding mesh blockage. This not only maintains the air permeability of the filter screen but also ensures the smooth flow of heat dissipation air, enabling the exhaust mechanism to maintain the quality of heat dissipation.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides, for example Figure 1-7 The leak-proof special gas holder shown includes a cabinet body 1, a partition 3, an exhaust mechanism 4, a sealing and fixing mechanism 5, and a cleaning mechanism 6. Filter screens 2 are fixedly installed on both sides of the cabinet body 1. The partition 3 is fixedly connected to the bottom of the inner wall of the cabinet body 1. The exhaust mechanism 4 is located on the cabinet body 1 to circulate the air inside the cabinet body 1. The sealing and fixing mechanism 5 is located inside the cabinet body 1 to fix and seal the gas cylinder. The cleaning mechanism 6 is connected to the sealing and fixing mechanism 5 and is used to clean the filter screens 2. The exhaust mechanism 4, in conjunction with the filter screens 2, can normally dissipate heat from the gas cylinder. The sealing and fixing mechanism 5 not only fixes the gas cylinder inside the cabinet body 1 but also automatically and promptly detects leaks at the top of the gas cylinder. Opening the treatment pipe 511 for filtering leaked gas also triggers a buzzer 524 to alert staff. This ensures heat dissipation while improving the safety and reliability of the special gas cabinet during use. It is easy to use, and when the sealing and fixing mechanism 5 uses a motor to drive the positioning plate 56 to fix or release the gas cylinder, the filter screen 2 can be cleaned. The elastic force of the second compression spring 65 ensures that the cleaning plate 63 and the filter screen 2 maintain full contact, effectively scraping away accumulated dust and fiber impurities and preventing mesh blockage. This not only maintains the air permeability of the filter screen 2 but also ensures smooth airflow for heat dissipation, allowing the exhaust mechanism 4 to maintain the quality of heat dissipation.

[0020] Specifically, the exhaust mechanism 4 includes a filter box 41, an exhaust pipe 42, a mounting bracket 43, and an exhaust fan 44. The filter box 41 is fixedly connected to the top of the cabinet 1. The top of the filter box 41 has a filter screen with a large aperture, mainly used to protect the internal exhaust fan 44 from problems such as reduced speed, abnormal noise, or even burnout of the exhaust fan 44 motor due to foreign objects getting tangled or blocked. This ensures the long-term stable operation of the heat dissipation and exhaust system. Its large aperture also minimizes airflow resistance, ensuring smooth ventilation and minimizing the impact on the exhaust fan 44's extraction efficiency, thus ensuring timely heat dissipation from the cabinet. The exhaust pipe 42 is symmetrically and interlocked with the cabinet. At the top of the cabinet 1, the exhaust pipe 42 connects the cabinet 1 and the filter box 41, ensuring that the exhaust fan 44 can draw the gas inside the cabinet 1 into the filter box 41 for discharge when it is running. The mounting bracket 43 is symmetrically fixed to both sides of the inner wall of the filter box 41. The exhaust fan 44 is fixedly installed inside the mounting bracket 43 to extract the gas inside the cabinet 1. The exhaust fan 44 is electrically connected to an external power supply through an external switch. The exhaust fan 44 can extract the gas inside the cabinet 1, forcing the internal air to flow, thereby accelerating the removal of the heat generated by the gas cylinder and related components during operation, achieving a continuous and stable heat dissipation effect.

[0021] Furthermore, the sealing and fixing mechanism 5 includes a fixing plate 51, a motor 52, a lead screw 53, a slide bar 54, a slider 55, a positioning plate 56, a bellows 57, a sealing ring 58, and a leakage handling assembly. The fixing plate 51 is fixedly connected to one side of the inner wall of the cabinet 1. A connecting pipe for connecting to a gas cylinder is also fixedly inserted on the fixing plate 51. This connecting pipe is fixedly inserted and inserted into the cabinet 1, facilitating connection to external equipment for immediate use of the internal gas. The partition 3 has an internal mounting groove, and the motor 52 is fixedly installed inside the mounting groove. The motor 52 is electrically connected to an external power source through an external switch. 2. The lead screw 53 can rotate in both directions, thereby allowing the positioning plate 56 to move vertically back and forth via the slider 55 under the limitation of the slide rod 54. After the gas cylinder is placed on both sides of the partition 3, the positioning groove on the positioning plate 56 can be used to limit and fix the gas cylinder. One end of the lead screw 53 is rotatably connected to the fixing plate 51, and the other end of the lead screw 53 is rotatably connected to the partition 3. The output end of the motor 52 is connected to the lead screw 53 for transmission. Slide grooves are provided on both sides of the inner wall of the cabinet 1. The end of the slide rod 54 is fixedly connected to the inner wall of the slide groove, and the slider 55 is slidably connected to the slide rod 54. The positioning plate 56 is connected to the lead screw 53 for transmission. The slider 55 is fixedly connected to both sides of the positioning plate 56. The bellows 57 is fixedly installed between the fixing plate 51 and the positioning plate 56 to cover the top of the gas cylinder. After the positioning plate 56 fixes the gas cylinder, the bellows 57 can be used to cover the top of the gas cylinder, thus forming a space for sealing the top of the gas cylinder with the fixing plate 51 and the positioning plate 56, which facilitates subsequent leakage treatment of the top of the gas cylinder. The positioning plate 56 has symmetrical positioning grooves, and the sealing ring 58 is embedded in the positioning groove to limit the displacement of the gas cylinder and seal the top of the gas cylinder. The setting of the sealing ring 58 is not... Working in conjunction with the positioning groove, it achieves a tight fit around the neck of the gas cylinder, effectively preventing displacement of the gas cylinder in the vertical and horizontal directions. Its elastic sealing material can fully fill the microscopic gaps on the surface of the gas cylinder, forming a reliable airtight isolation layer. This ensures the integrity of the closed space formed by the bellows 57, preventing leaked gas from overflowing. Its highly elastic rubber material also plays a good role in buffering and protection, avoiding direct rigid contact between metal parts and the gas cylinder body, preventing scratches on the cylinder body during the fixing process, improving operational safety and extending the service life of the equipment. The leak handling component is located at the top of the fixing plate 51.

[0022] Furthermore, the leak handling assembly includes a handling plate 59, a filter plate 510, a handling pipe 511, a valve opening and closing assembly, and an early warning assembly. The handling plate 59 is fixedly connected to the top of the inner wall of the cabinet 1. The interior of the handling plate 59 has symmetrically arranged filter grooves. The filter plate 510 is slidably inserted into the inner cavity of the filter groove. The filter plate 510 can be replaced according to the gas cylinders containing different gases, so that harmful gases can be filtered in a targeted manner when a leak occurs. The handling pipe 511 is fixedly connected to the top and bottom of the handling plate 59. The handling pipe 511 is fixedly inserted into the fixed plate 51. The valve opening and closing assembly is set between the fixed plate 51 and the handling pipe 511 for opening and closing the handling pipe 511. The early warning assembly is set on the cabinet 1 and can issue a timely warning when a leak occurs, reminding the staff to handle the situation.

[0023] Furthermore, the valve opening and closing assembly includes a valve 512, a valve stem 513, a gear 514, a fixed cylinder 515, a pressing plate 516, a rack 517, and a first compression spring 518. The valve 512 is mounted on the processing pipe 511, and the valve stem 513 is rotatably mounted on the valve 512 for opening and closing the processing pipe 511. The gear 514 is fixedly inserted into the valve stem 513. The fixed cylinder 515 is symmetrically fixedly connected to the top of the fixed plate 51. The pressing plate 516 is slidably inserted into the inner cavity of the fixed cylinder 515. The rack 517 is fixedly connected to the top of the pressing plate 516 and passes through the fixed cylinder 515 to mesh with the gear 514. The first compression spring 518 is... Inside the fixed cylinder 515, one end of the first compression spring 518 is fixedly connected to the extrusion plate 516, and the other end of the first compression spring 518 is fixedly connected to the bottom end of the inner wall of the fixed cylinder 515. The first compression spring 518 always provides a stable upward elastic force to the extrusion plate 516, so that when the extrusion plate 516 is released, the rack 517 can be ejected in time under the elastic force of the first compression spring 518, and drive the gear 514 to rotate, so that the valve stem 513 rotates to open the valve 512, thereby opening the treatment pipe 511 in time when there is a leak, so that the leaked gas can be treated by the corresponding filter plate 510 before being discharged.

[0024] Furthermore, the valve opening and closing assembly also includes a sleeve 519, a piston rod 520, a snap-fit ​​rod 521, and a pressing rod 522. The sleeve 519 is symmetrically fixedly embedded inside the fixed plate 51. The piston rod 520 is slidably inserted into the inner cavity of the sleeve 519. A positioning groove is formed on the outer wall of the sleeve 519. A snap-fit ​​hole is formed on the outer wall of the pressing plate 516. One end of the snap-fit ​​rod 521 is slidably inserted into the inner cavity of the positioning groove, and the other end of the positioning rod passes through the fixed cylinder 515 and is slidably inserted into the inner cavity of the positioning hole. The piston rod 520 is slidably inserted into the inner cavity of the snap-fit ​​rod 521. The pressing rod 522 is fixedly connected to both sides of the piston rod 520. A pressing groove is formed on both sides of the inner wall of the snap-fit ​​rod 521. The pressing rod 522 is slidably inserted into the inner cavity of the pressing groove. Under normal conditions, the piston rod 520... Figure 5 As shown, in this state, the clamping rod 521 can be extended by the squeezing rod 522 to position the squeezing plate 516, and the rack 517 can fix the gear 514. At this time, the valve 512 is in the closed state, which makes it easy to keep the space formed by the bellows 57, the fixing plate 51, and the positioning plate 56 in a sealed state. When the internal gas cylinder leaks, the internal gas can gradually increase, thereby pushing the piston rod 520 up, which allows the clamping rod 521 to slide and disengage from the clamping hole. Under the elastic force of the first compression spring 518, the rack 517 can be ejected in time and drive the gear 514 to rotate, causing the valve rod 513 to rotate and open the valve 512. Thus, the treatment pipe 511 can be opened in time when there is a leak, so that the leaked gas can be treated by the corresponding filter plate 510 before being discharged.

[0025] Furthermore, the warning component includes a switch button 523 and a buzzer 524. The switch button 523 is symmetrically fixedly installed at the bottom of the fixing plate 51, and the buzzer 524 is symmetrically fixedly connected to both ends of the cabinet 1. The switch button 523 and the buzzer 524 are electrically connected. When the rack 517 pops up, the top of the rack 517 will press the switch button 523, thereby making the buzzer 524 sound, which can conveniently remind nearby staff that the gas cylinder is leaking and can be dealt with in a timely manner.

[0026] Specifically, the cleaning mechanism 6 includes a connecting rod 61, a connecting plate 62, a cleaning plate 63, a limiting rod 64, and a second compression spring 65. The connecting rod 61 is symmetrically and fixedly connected to the bottom end of the positioning plate 56. The connecting plate 62 is fixedly connected to the bottom end of the connecting rod 61. The cleaning plate 63 is slidably inserted into the inner cavity of the connecting plate 62. Limiting grooves are equidistantly formed on the inner wall of the connecting plate 62. One end of the limiting rod 64 is fixedly connected to the cleaning plate 63, and the other end of the limiting rod 64 is slidably inserted into the inner cavity of the limiting groove. One end of the second compression spring 65 is fixedly connected to the inner wall of the limiting groove. The other end of the spring 65 is fixedly connected to the limiting rod 64. When the positioning plate 56 moves back and forth in the vertical direction, it can fix or release the gas cylinder. In either case, the connecting rod 61 can drive the connecting plate 62 to move in the vertical direction. Under the elastic force of the second compression spring 65, the cleaning plate 63 and the filter screen 2 can maintain full contact, effectively scraping away accumulated dust and fiber impurities, avoiding mesh blockage. This not only maintains the air permeability of the filter screen 2, but also ensures the smooth flow of heat dissipation air, so that the exhaust mechanism 4 can maintain the quality of heat dissipation.

[0027] Furthermore, a sealing door 7 is rotatably mounted on the cabinet 1, and an observation window is embedded in the sealing door 7. The observation window is made of transparent material, and the edge of the sealing door 7 is embedded with a corrosion-resistant silicone sealing strip. When the door is closed, it can be locked by a lock to achieve a tight fit with the cabinet 1, ensuring that the inside of the cabinet is sealed. The observation window is made of high-strength, impact-resistant transparent polycarbonate material, and its inner surface is often covered with an explosion-proof film and an anti-condensation coating. While maintaining a wide field of vision, it can effectively resist unexpected internal pressure impacts and prevent water vapor condensation, achieving uninterrupted, high-definition visual monitoring.

[0028] How to use this invention: Step 1: Initial preparation and gas cylinder placement. Open the sealed door 7 of cabinet 1, place the gas cylinder securely on partition 3, and ensure that the top of the gas cylinder faces the direction of fixed plate 51 and that the connecting pipe is connected to the interface of the gas cylinder. Then, according to the characteristics of the gas in the gas cylinder, select and install a filter plate 510 that can effectively filter the leaked gas in the filter groove of the treatment plate 59. Step 2: The gas cylinder is fixed and a sealed space is established. Start the motor 52 and drive the lead screw 53 to rotate, which drives the positioning plate 56 to move down smoothly under the guidance of the slide rod 54. The positioning plate 56 hugs and secures the neck of the gas cylinder through the sealing ring 58 embedded inside it. At the same time, the bellows 57 fixed between the fixing plate 51 and the positioning plate 56 extends, together with the two to form a sealed space that completely covers the top of the gas cylinder. Step 3: System operation and status monitoring. After closing the sealing door 7, turn on the exhaust fan 44 of the exhaust mechanism 4 to force the air inside the cabinet 1 to be drawn into the filter box 41 through the exhaust pipe 42 and then discharged, forming a stable airflow circulation to provide continuous heat dissipation for the gas cylinder and related components. Step 4: Automatic Leakage Response and Emergency Handling. When a leak occurs at the top of the gas cylinder, the leaking gas accumulates and the pressure increases in the sealed space formed by the bellows 57. This pressure pushes the piston rod 520 of the valve opening and closing assembly upward, thereby releasing the lock on the rack 517 through mechanical linkage. Driven by the first compression spring 518, the rack 517 instantly springs up. On the one hand, it drives the gear 514 and the valve rod 513 to rotate, immediately opening the valve 512 of the treatment pipe 511, guiding the leaking gas through the filter plate 510 for purification and safe discharge. On the other hand, the springing rack 517 will trigger the switch button 523 of the warning assembly, activating the buzzer 524 installed on the cabinet 1 to issue an alarm to notify the staff to handle the situation. Step 5: In daily use, each time the positioning plate 56 moves up and down to fix or release the gas cylinder, the cleaning mechanism 6 connected to it via the connecting rod 61 will rise and fall synchronously. Under the action of the second compression spring 65, the cleaning plate 63 in the mechanism always fits tightly against the surface of the filter screen 2 on both sides of the cabinet 1, automatically scraping off the attached impurities, maintaining the air permeability and heat dissipation efficiency of the filter screen 2, and ensuring that the equipment is in the best working condition.

10. A method of using a leak-proof special gas holder according to any one of claims 1-9, characterized in that, The specific usage steps are as follows: Step 1: Initial preparation and gas cylinder placement. Open the sealed door (7) of the cabinet (1), place the gas cylinder securely on the partition (3), and ensure that the top of the gas cylinder faces the fixed plate (51) and the connecting pipe is connected to the interface of the gas cylinder. According to the gas characteristics inside the gas cylinder, select and install a filter plate (510) that can effectively filter the leaked gas in the filter groove of the treatment plate (59). Step 2: The gas cylinder is fixed and a sealed space is established. Start the motor (52) and drive the lead screw (53) to rotate, which will drive the positioning plate (56) to move down smoothly under the guidance of the slide bar (54). The positioning plate (56) hugs and secures the neck of the gas cylinder through the sealing ring (58) embedded inside it. At the same time, the bellows (57) fixed between the fixing plate (51) and the positioning plate (56) extends and together with the two forms a sealed space that completely covers the top of the gas cylinder. Step 3: System operation and status monitoring. After closing the sealed door (7), turn on the exhaust fan (44) of the exhaust mechanism (4) to force the air inside the cabinet (1) to be drawn into the filter box (41) through the exhaust pipe (42) and then discharged, forming a stable airflow circulation to provide continuous heat dissipation for the gas cylinder and related components. Step 4: Automatic response and emergency handling of leaks. When a leak occurs at the top of the gas cylinder, the leaked gas accumulates and the pressure increases in the sealed space formed by the bellows (57). This pressure pushes the piston rod (520) of the valve opening and closing assembly to move upward, thereby releasing the lock on the rack (517) through mechanical linkage. Driven by the first compression spring (518), the rack (517) bounces up instantly. On the one hand, it drives the gear (514) and valve rod (513) to rotate, immediately opening the valve (512) of the treatment pipe (511) and guiding the leaked gas to flow through the filter plate (510) for purification and safe discharge. On the other hand, the bounced rack (517) will trigger the switch button (523) of the warning assembly, start the buzzer (524) installed on the cabinet (1), and issue an alarm to notify the staff to handle the situation. Step 5: Automatic cleaning and system maintenance. In daily use, each time the positioning plate (56) moves up and down to fix or release the gas cylinder, the cleaning mechanism (6) connected to it via the connecting rod (61) will rise and fall synchronously. Under the action of the second compression spring (65), the cleaning plate (63) in the mechanism always fits tightly against the surface of the filter screen (2) on both sides of the cabinet (1), automatically scraping off the attached impurities, maintaining the air permeability and heat dissipation efficiency of the filter screen (2), and ensuring that the equipment is in the best working condition.
