Description
Technical Field
[0001] The utility model relates to the field of protection technology, in particular to a special gas cabinet with multi-layer protection. Background Art
[0002] With the continuous development of the chemical industry, various chemical gases are widely used in industry. Due to their physical and chemical properties, gases are also highly dangerous. Therefore, special gas cabinets are needed to collect and store them. Special gas cabinets are mainly used to supply special gases, such as flammable, explosive, and highly toxic gases.
[0003] Existing special gas cabinets with multi-layer protection generally only rely on the solid outer cabinet structure and the internal neutralization and adsorption treatment mechanism to prevent gas leakage. Once a leak occurs, the leaked gas will directly contact the cabinet and affect it, which may not only damage the cabinet, but also increase the difficulty of subsequent cleaning work on the cabinet. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a special gas cabinet with multi-layer protection to solve the technical problem that the special gas directly contacts the cabinet body after leakage.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special gas cabinet with multi-layer protection, comprising a cabinet body, a storage ring is fixedly connected to the top of the cabinet body, a sealing cover is fixedly connected to the inside of the storage ring, a clamping rod is fixedly connected to the bottom of the sealing cover, a rotating ring is provided on one side of the clamping rod, a block is fixedly connected to one side of the rotating ring, an inner rod is fixedly connected to one side of the block, an outer tube is provided on the outer side of the inner rod.
[0006] By adopting the above technical solution, the neutralizing liquid bottle sprays the neutralizing liquid outward through the injector and nozzle provided therewith, so that the leaked liquid can be effectively neutralized in the sealed cover, thereby preventing the accumulation of harmful gases inside and avoiding possible dangers.
[0007] Furthermore, a reinforcement ring is fixedly connected to the sealing cover, and a plurality of the reinforcement rings are provided, and the plurality of reinforcement rings are evenly arranged at equal distances.
[0008] By adopting the above technical solution, the sealing cover can more firmly maintain its shape and function when subjected to internal pressure impact, and effectively prevent gas leakage caused by deformation or damage.
[0009] Furthermore, an L-shaped sliding groove is provided on the rotating ring, and the L-shaped sliding groove is matched with the clamping rod.
[0010] By adopting the above technical solution, the fixing and unlocking operations of the sealing cover are made more convenient and reliable. The special shape of the L-shaped slide groove ensures that the clamping rod can be firmly locked on the rotating ring after insertion, thereby effectively maintaining the sealing cover in a closed state and preventing gas leakage.
[0011] Furthermore, a mounting groove is fixedly connected to the bottom of the cabinet, and a steel cylinder is arranged inside the mounting groove.
[0012] By adopting the above technical solution, it is ensured that the steel cylinder can be stably fixed in the installation groove, and the steel cylinder is effectively prevented from moving or tipping over due to external force or its own weight.
[0013] Furthermore, the outer tube is fixedly connected to the mounting groove, a nozzle is provided below the stopper, and a neutralizing liquid bottle is fixedly connected to the bottom of the nozzle.
[0014] By adopting the above technical solution, the structural stability of the special gas cabinet is enhanced, and the position fixation and normal function of the outer tube and its internal components during the use of the special gas cabinet are ensured.
[0015] Furthermore, four clamping rods are provided, and the four clamping rods are evenly arranged in a ring shape along the center line of the sealing cover.
[0016] By adopting the above technical solution, the four clamping rods are evenly distributed to jointly bear and disperse possible external forces or internal pressures, effectively preventing overall structural damage caused by single point failure and enhancing the stability of the connection between the sealing cover and the rotating ring.
[0017] Furthermore, a sliding sealing sheet is provided between the inner rod and the outer tube, and a sealing space is provided between the sliding sealing sheet and the outer tube.
[0018] By adopting the above technical solution, a variable sealing space is formed by setting a sliding sealing plate between the inner rod and the outer tube, so that when the internal pressure of the special gas cabinet changes, the sliding sealing plate can flexibly respond and move, thereby adjusting the volume of the sealing space.
[0019] Furthermore, the interior of the sealed space is filled with helium at normal pressure.
[0020] By adopting the above technical solution, the presence of normal pressure helium provides a reliable reference pressure point for the special gas cabinet, so that when abnormal situations such as gas leakage occur, the system can quickly sense the pressure change.
[0021] Furthermore, a slope is provided on one side of the top of the L-shaped slide groove.
[0022] By adopting the above technical solution, the existence of the inclined surface reduces the friction resistance between the rotating ring and the clamping rod, thereby reducing the difficulty of operation and the required force, so that the rotating ring can be rotated more easily and smoothly when it needs to be rotated.
[0023] Furthermore, the sealing cover is made of polycarbonate.
[0024] By adopting the above technical solution, the polycarbonate material has excellent impact resistance and high strength, so that the sealing cover can withstand external physical shock and pressure, and effectively protect the gas inside the special gas cabinet from external damage.

[0027] 2. The utility model provides a reinforcement ring, which is fixedly connected to the sealing cover, which can effectively disperse and absorb external impact or pressure, prevent the sealing cover from being deformed or damaged when subjected to external force, thereby ensuring that the gas inside the special gas cabinet is reliably protected;
[0028] 3. The utility model sets a sealing cover as an important safety barrier to prevent harmful gases from leaking from the inside of the special gas cabinet to the external environment, thereby avoiding potential safety risks and environmental pollution. At the same time, the polycarbonate material also has good transparency, so that the sealing cover remains strong and durable while allowing the operator to clearly observe the situation inside the special gas cabinet, thereby improving safety.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0035] The following describes an embodiment of the utility model based on its overall structure.
[0036] Embodiment 1:
[0037] A special gas cabinet with multiple layers of protection, such as Figure 1-Figure 4 As shown, it includes a cabinet 1, a storage ring 2 is fixedly connected to the top of the cabinet 1, a sealing cover 3 is fixedly connected to the inside of the storage ring 2, a clamping rod 5 is fixedly connected to the bottom of the sealing cover 3, a rotating ring 6 is arranged on one side of the clamping rod 5, a stopper 7 is fixedly connected to one side of the rotating ring 6, an inner rod 8 is fixedly connected to one side of the stopper 7, an outer tube 9 is sleeved on the outer side of the inner rod 8, and the neutralizing liquid bottle 17 is sprayed outwardly through the self-provided injector and nozzle 15, so that the leaked liquid can be effectively neutralized in the sealing cover 3, and the harmful gas inside can be prevented from gathering, and the possible danger can be avoided. When the internal air pressure continues to increase, the helium filled in the sealing space 14 will be compressed, thereby driving the rotating ring 6 to continue to rotate, and the clamping rod 5 will escape from the inside of the L-shaped slide groove 10, so that the gas in the sealing cover 3 can be dissipated to the inside of the cabinet 1, so as to realize multi-stage pressure relief, which can not only effectively prevent the danger of explosion caused by excessive internal air pressure, but also ensure the stable operation of the special gas cabinet under extreme conditions.
[0038] See also Figure 3 A reinforcement ring 4 is fixedly connected to the sealing cover 3, and a plurality of reinforcement rings 4 are provided, and the plurality of reinforcement rings 4 are evenly arranged at equal distances, so that the sealing cover 3 can more firmly maintain its shape and function when subjected to internal pressure impact, and effectively prevent gas leakage caused by deformation or damage. When the sealing cover 3 inside the storage ring 2 on the top of the cabinet 1 needs to be pulled downward, the presence of the reinforcement ring 4 also provides additional support and guidance, making the pulling-out process of the sealing cover 3 smoother and more reliable.
[0039] See also Figure 3 and Figure 4An L-shaped slot 10 is provided on the rotating ring 6, and the L-shaped slot 10 is matched with the clamping rod 5, making the fixing and unlocking operations of the sealing cover 3 more convenient and reliable. The special shape of the L-shaped slot 10 ensures that the clamping rod 5 can be firmly locked on the rotating ring 6 after insertion, thereby effectively maintaining the closed state of the sealing cover 3 to prevent gas leakage. When the unlocking operation is required, the clamping rod 5 only needs to be moved along the path of the L-shaped slot 10 through a specific operation, so as to easily release the sealing cover 3 from the locked state, which not only simplifies the operating process and improves work efficiency, but also can respond quickly in emergency situations to ensure the safe use of the special gas cabinet.
[0040] See also Figure 2 , Figure 3 and Figure 4 The bottom of the cabinet 1 is fixedly connected with a mounting groove 11, and a steel cylinder 12 is arranged inside the mounting groove 11, ensuring that the steel cylinder 12 can be stably fixed in the mounting groove 11, and effectively preventing the steel cylinder 12 from moving or tipping over due to external force or its own weight. The internal structure and size of the mounting groove 11 match the steel cylinder 12, further enhancing the stability and safety of the steel cylinder 12 during the installation process.
[0041] See also Figure 2 , Figure 3 and Figure 4 The outer tube 9 and the mounting groove 11 are fixedly connected, a nozzle 15 is arranged below the block 7, and a neutralizing liquid bottle 17 is fixedly connected to the bottom of the nozzle 15, which enhances the structural stability of the special gas cabinet and ensures that the outer tube 9 and its internal components are fixed in position and function normally during the use of the special gas cabinet. At the same time, a nozzle 15 is arranged below the block 7, and the bottom of the nozzle 15 is fixedly connected to the neutralizing liquid bottle 17, so that when a gas leak occurs, the neutralizing liquid can be quickly and accurately sprayed to the leakage point through the nozzle 15, effectively neutralizing the harmful gas and reducing the risk of leakage.
[0042] See also Figure 2 There are four clamping rods 5, and the four clamping rods 5 are evenly arranged in a ring shape along the center line of the sealing cover 3. The four clamping rods 5 are evenly distributed, and jointly bear and disperse possible external forces or internal pressures, effectively preventing the overall structural damage caused by single point failure, and enhancing the connection stability between the sealing cover 3 and the rotating ring 6. The annular arrangement of the four clamping rods 5 also ensures the uniformity and stability of the sealing cover 3 when subjected to force, avoiding deformation or damage caused by local stress concentration, which not only improves the safety of the special gas cabinet during use, but also extends its service life and reliability.
[0043] See also Figure 2A sliding sealing sheet 13 is provided between the inner rod 8 and the outer tube 9, and a sealing space 14 is provided between the sliding sealing sheet 13 and the outer tube 9. By providing the sliding sealing sheet 13 between the inner rod 8 and the outer tube 9, a variable sealing space 14 is formed, so that when the internal pressure of the special gas cabinet changes, the sliding sealing sheet 13 can flexibly respond and move, thereby adjusting the volume of the sealing space 14. When the internal pressure increases, the sliding sealing sheet 13 is pushed to slide into the outer tube 9, which not only changes the size of the sealing space 14, but also drives the inner rod 8 to slide inward through the connection between the inner rod 8 and the sliding sealing sheet 13. The sliding of the inner rod 8 is further transmitted to the rotating ring 6 connected thereto, causing the rotating ring 6 to rotate, ensuring that the special gas cabinet can respond quickly and accurately when facing pressure changes, thereby effectively protecting the special gas stored inside from damage.
[0044] See also Figure 2 The interior of the sealed space 14 is filled with helium at normal pressure. The presence of helium at normal pressure provides a reliable reference pressure point for the special gas cabinet, so that when an abnormal situation such as gas leakage occurs, the system can quickly sense the pressure change. When the gas inside the internal sealing cover 3 leaks, since the helium filled in the sealed space 14 is at normal pressure, the leakage may cause the pressure inside the sealing cover 3 to rise. This pressure change causes a pressure difference on both sides of the sliding sealing piece 13, thereby pushing the sliding sealing piece 13 to slide into the outer tube 9, which not only responds to the leakage in time, but also effectively triggers the safety protection mechanism of the special gas cabinet.
[0045] See also Figure 3 and Figure 4 A slope 16 is provided on one side of the top of the L-shaped slide groove 10. The existence of the slope 16 reduces the friction resistance between the rotating ring 6 and the clamping rod 5, thereby reducing the difficulty of operation and the required force, so that the rotating ring 6 can be rotated more easily and smoothly when it needs to be rotated. During the operation, the clamping rod 5 can slide smoothly into the slide groove along the slope 16, avoiding jamming or damage caused by inaccurate alignment or insufficient force, and helping the clamping rod 5 to be more accurately inserted into the L-shaped slide groove 10.
[0046] The implementation principle of the utility model is as follows: first, install the steel cylinder 12 into the installation groove 11 so that the steel cylinder 12 is stably fixed, and then pull the sealing cover 3 inside the storage ring 2 at the top of the cabinet 1 downward, at this time, the clamping rod 5 at the bottom of the sealing cover 3 can easily rotate the rotating ring 6 through the inclined surface 16, so that the clamping rod 5 is convenient for clamping into the L-shaped sliding groove 10;
[0047] When the gas inside the internal sealing cover 3 leaks, since the helium filled in the sealed space 14 is at normal pressure, a pressure difference is generated on both sides of the sliding sealing sheet 13, pushing the sliding sealing sheet 13 to slide inside the outer tube 9, driving the inner rod 8 to slide inside, and then driving the rotating ring 6 to rotate, and the rotating ring 6 drives the stopper 7 to move, making space so that the nozzle 15 at the bottom of the stopper 7 is exposed, and the neutralizing liquid bottle 17 sprays the neutralizing liquid outward through the nozzle 15 through the self-contained injector to neutralize the leaked liquid, prevent the harmful gas inside from gathering, and sound an alarm;
[0048] When the internal air pressure continues to increase, the helium filled in the sealed space 14 continues to be compressed, driving the rotating ring 6 to continue to rotate. At this time, the clamping rod 5 escapes from the L-shaped sliding groove 10, allowing the gas in the sealing cover 3 to escape into the cabinet 1, achieving multi-stage pressure relief.
[0049] Embodiment 2:
[0050] See also Figure 1 and Figure 3 The sealing cover 3 is made of polycarbonate, which has excellent impact resistance and high strength, so that the sealing cover 3 can withstand external physical impact and pressure, and effectively protect the gas inside the special gas cabinet from external damage. The polycarbonate material also has good transparency, so that the sealing cover 3 can remain strong and durable while allowing the operator to clearly observe the situation inside the special gas cabinet, which helps to detect abnormal situations in time and take corresponding treatment measures, thereby further improving the safety of the special gas cabinet.
[0051] The implementation principle of the utility model is that the polycarbonate material is a transparent material, so that when the special colored gas leaks, it is convenient for the staff to observe.
[0052] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
[0053] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
