Description

Technical Field

[0001] This utility model belongs to the field of gas storage technology, specifically a special gas cabinet with a protective device. Background Technology

[0002] Special gas holders are key safety equipment for handling high-purity and highly hazardous gases in modern industrial production. They are widely used in laboratories, semiconductor chip manufacturing, photovoltaic industry, pharmaceuticals and bioengineering, mainly due to their mandatory requirements for safety control, process purity and operational stability.

[0003] The principle of special gas cabinets with protective devices mainly involves two aspects: physical isolation and gas leak monitoring. Through the application of precise physical isolation and gas leak monitoring principles, special gas cabinets with protective devices can efficiently monitor leaks of internal special gases, providing strong support for the use of special gases.

[0004] Existing special gas holders, when requiring rapid disassembly of the gas tank in an emergency, mostly rely on finding specific tools and loosening multiple fasteners to disassemble the tank. Since loosening and removing these components one by one is time-consuming, it increases personnel safety risks. Therefore, to address these issues, a special gas holder with a protective device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a special gas cabinet with a protective device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a special gas cabinet with a protective device, including a cabinet body. Cabinet doors are rotatably installed on both sides of the interior of the cabinet body. Handles are fixedly installed on the outer sides of the cabinet doors. Multiple mounting bases and fixing blocks are fixedly installed at both ends of the inner wall of the cabinet body. An irregular rotating plate is provided inside the mounting base. A limit rod is fixedly installed inside the irregular rotating plate. Both ends of the limit rod are rotatably installed on the inner wall of the mounting base. Springs are fixedly installed at both ends on one side of the inner wall of the mounting base. One end of one spring is fixedly installed on the outside of the irregular rotating plate, and one end of the other spring is fixedly installed with a moving block. One end of the irregular rotating plate is tightly attached to a pressing rod, which is slidably mounted inside the mounting base. The other end of the irregular rotating plate is tightly attached to a connecting rod, and a mounting groove is provided on one side of the connecting rod. One end of the irregular rotating plate is mounted inside the mounting groove on the side of the connecting rod. By pressing the pressing rod inward, one end of the irregular rotating plate is moved downward. When one end of the irregular rotating plate moves downward, the other end moves upward. When one end of the irregular rotating plate moves upward, it will disengage from the limiting relationship between itself and the mounting groove in the connecting rod. At this point, the connecting rod can be pulled out to remove the gas storage tank.

[0007] Preferably, connecting plates are fixedly installed at both ends of the outer side of the fixing block, and a rotating rod is provided between the multiple connecting plates. A bolt is fixedly installed inside the rotating rod, and the bolt passes through the internal thread of one connecting plate and is installed inside the other connecting plate. A binding strap is fixedly installed on the outer side of the rotating rod, and a fixing plate is fixedly installed on one end of the binding strap. One end of the connecting rod is fixedly installed on the side of the fixing plate. The rotating rod is driven to rotate by rotating the bolt. When the rotating rod rotates, it will cause one end of the binding strap fixedly installed on its outside to wrap around the outside of the rotating rod, ultimately achieving the effect of adjusting the length of the binding strap.

[0008] Preferably, a support base is fixedly installed at the bottom of the inner wall of the cabinet, and a buffer pad is provided inside the support base. The buffer pad is made of rubber. The elasticity and compressibility of the rubber material can effectively absorb and disperse this impact energy, making the gas storage tank more stable when stored.

[0009] Preferably, an electrochemical sensor is fixedly installed on the top of the cabinet, and the detection end of the electrochemical sensor is located inside the cabinet. Warning lights are installed at both ends of the internal part of the electrochemical sensor. By placing the detection end of the electrochemical sensor inside the cabinet, the effect of real-time detection of special gases inside the cabinet can be achieved.

[0010] Preferably, a control panel is fixedly installed on the outside of the cabinet door. The electrochemical sensor and the warning light are electrically connected to the control panel. The control panel is used to control their start and stop. The electrochemical sensor sends a signal to the control panel to cause the warning light to issue a warning, which is used to remind the staff.

[0011] Preferably, each of the cabinet doors is equipped with a viewing window made of glass. The viewing window allows for observation of the gas tank inside the cabinet without frequently opening the cabinet door.

[0012] The advantages of this utility model are:

[0013] This invention uses an inward pressing rod to move one end of an irregular rotating plate downwards. When one end of the irregular rotating plate moves downwards, it causes the other end to move upwards. When one end of the irregular rotating plate moves upwards, it disengages from the limiting relationship between itself and the mounting groove inside the connecting rod. At this point, the connecting rod can be pulled out to remove the gas tank. This allows for the disassembly of the gas tank to be completed in just two steps: pressing and pulling. The operation is simple and efficient, minimizing the time that operators are exposed to hazardous environments. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a special gas cabinet with a protective device includes a cabinet body 1. Cabinet doors 2 are rotatably mounted on both sides of the interior of the cabinet body 1. Handles 3 are fixedly mounted on the outer sides of the cabinet doors 2. Multiple mounting bases 4 and fixing blocks 5 are fixedly mounted on both ends of the inner wall of the cabinet body 1. An irregular rotating plate 6 is provided inside the mounting base 4. Limiting rods 7 are fixedly mounted inside the irregular rotating plate 6, with both ends of the limiting rods 7 rotatably mounted on the inner wall of the mounting base 4. Springs 8 are fixedly mounted on both ends of one side of the inner wall of the mounting base 4. One end of one spring 8 is fixedly mounted on the outside of the irregular rotating plate 6, and one end of the other spring 8 is fixedly mounted on a moving block 9. A pressing rod 10 is tightly attached to the outside of one end of the irregular rotating plate 6, and the outside of the pressing rod 10 slides... The irregular rotating plate 6 is installed inside the mounting base 4. The other end of the irregular rotating plate 6 is closely attached to the connecting rod 11. An installation groove 12 is opened on one side of the connecting rod 11. One end of the irregular rotating plate 6 is installed inside the installation groove 12 opened on the side of the connecting rod 11. During operation, in order to replace and disassemble the gas tank more quickly, the pressing rod 10 is pressed inward to make one end of the irregular rotating plate 6 move downward. When one end of the irregular rotating plate 6 moves downward, it will make the other end move upward. When one end of the irregular rotating plate 6 moves upward, one end of the irregular rotating plate 6 will disengage from the limiting relationship between the irregular rotating plate 6 and the installation groove 12 opened in the connecting rod 11. At this time, the connecting rod 11 can be pulled out to achieve the effect of removing the gas tank.

[0023] Both ends of the outer side of the fixing block 5 are fixedly installed with connecting plates 17. A rotating rod 15 is provided between multiple connecting plates 17. A bolt 16 is fixedly installed inside the rotating rod 15, and the bolt 16 passes through the internal thread of one connecting plate 17 and is installed inside another connecting plate 17. A binding strap 14 is fixedly installed on the outer side of the rotating rod 15. A fixing plate 13 is fixedly installed on the outer side of one end of the binding strap 14. One end of the connecting rod 11 is fixedly installed on the side of the fixing plate 13. During operation, in order to adapt the binding strap 14 to different sizes of gas storage tanks and fix them, the rotating rod 15 is rotated by rotating the bolt 16. When the rotating rod 15 rotates, it will cause one end of the binding strap 14 fixedly installed on its outer side to wrap around the outside of the rotating rod 15, thus achieving the effect of adjusting the length of the binding strap 14.

[0024] A support base 18 is fixedly installed on the bottom of the inner wall of the cabinet 1. The support base 18 has a buffer pad 19 inside, which is made of rubber. During operation, in order to reduce the impact when the gas tank is placed, the elasticity and compressibility of the rubber material can effectively absorb and disperse this impact energy, making the gas tank more stable when stored.

[0025] An electrochemical sensor 21 is fixedly installed on the top of the cabinet 1. The detection end of the electrochemical sensor 21 is located inside the cabinet 1. Warning lights 22 are installed at both ends of the electrochemical sensor 21. During operation, in order to detect special gases inside the cabinet 1, the detection end of the electrochemical sensor 21 is located inside the cabinet 1 to achieve the effect of real-time detection of special gases inside the cabinet 1.

[0026] A control panel 23 is fixedly installed on the outside of the cabinet door 2. The electrochemical sensor 21 and the warning light 22 are electrically connected to the control panel 23. The control panel 23 is used to control their start and stop. When working, if there is a gas leak inside the cabinet 1, the electrochemical sensor 21 sends a signal to the control panel 23 to make the warning light 22 issue a warning to remind the staff.

[0027] Each of the cabinet doors 2 has a viewing window 24 installed inside. The viewing window 24 is made of glass. During operation, in order to make it easier to observe the gas tank, the viewing window 24 made of glass can achieve the effect of observing the gas tank in the cabinet 1 without frequently opening the cabinet door 2.

[0028] Working principle: In existing special gas cabinets, when a gas storage tank needs to be quickly disassembled in an emergency, it is mostly done by finding specific tools and loosening multiple fasteners to disassemble the gas storage tank. Since loosening and removing these parts one by one takes a lot of time, it will increase the safety risks to personnel. When special gases need to be stored, the gas storage tank containing the special gas is first placed inside the support base 18. Then, the end of the binding strap 14 with the connecting rod 11 is inserted into the mounting base 4. At this time, the moving block 9 moves backward. When the moving block 9 moves backward, the mounting groove 12 opened inside the connecting rod 11 is blocked by one end of the irregular rotating plate 6. At this time, the connecting rod 11 cannot move horizontally, thus achieving the effect of installing the binding strap 14. Then, the rotating rod 15 is rotated by rotating the bolt 16. When the rotating rod 15 rotates, it will cause one end of the externally fixed binding strap 14 to wrap around the outside of the rotating rod 15, thus achieving the effect of adjusting the length of the binding strap 14 and fixing gas storage tanks of different sizes.

[0029] When it is necessary to quickly disassemble the gas tank, press the pressing rod 10 inward to move one end of the irregular rotating plate 6 downward. When one end of the irregular rotating plate 6 moves downward, it will move the other end upward. When one end of the irregular rotating plate 6 moves upward, it will disengage from the limiting relationship between the irregular rotating plate 6 and the mounting groove 12 opened in the connecting rod 11. At this time, pull out the connecting rod 11 to remove the gas tank. The gas tank can be disassembled in just two steps: pressing and pulling. The operation is simple and efficient, and the time that the operator is exposed to the dangerous environment is minimized.
