Description

Technical Field

[0001] This utility model relates to the field of laboratory supplies technology, and further to a novel fireproof and explosion-proof gas cylinder safety cabinet. Background Technology

[0002] Gas cylinders are typically used to store flammable, explosive, toxic, or highly corrosive gases, such as hydrogen, oxygen, and acetylene. If these gases leak or explode, they can cause fires, poisoning, or even catastrophic accidents, resulting in serious casualties and property damage. Therefore, gas cylinder cabinets are commonly used to store gas cylinders. A gas cylinder cabinet is a metal container used to improve local exhaust ventilation, protect gas cylinders from external fires, and protect surrounding objects from internal fires. Gas cylinder cabinets are commonly used in laboratories or factories. Their structure generally includes a cabinet body. Traditional cabinets are mostly single-layer sheet metal structures, lacking professional fire and explosion protection functions, and cannot effectively isolate fire or explosion risks. This means that in the event of a fire or leak inside the gas cylinder cabinet, personnel cannot be alerted in time or effectively protected, and there is also the possibility that external fires could damage the gas cylinders.

[0003] Therefore, there is an urgent need to develop a new type of fireproof and explosion-proof gas cylinder safety cabinet to solve the technical problem of poor fire protection function of existing gas cylinder cabinets. Utility Model Content

[0004] In view of the above-mentioned technical problems, the purpose of this utility model is to provide a new type of fireproof and explosion-proof gas cylinder safety cabinet, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel fireproof and explosion-proof gas cylinder safety cabinet includes: a cabinet body, a storage cavity inside the cabinet body, a plurality of supports for storing gas cylinders to be stored in the storage cavity, an opening on the side wall of the cabinet body, and a cabinet door corresponding to the opening, and an exhaust outlet on the cabinet body.

[0007] A sensing and monitoring system is installed inside the storage cavity, and the sensing and monitoring system is used to monitor the pressure, temperature and humidity parameters inside the storage cavity in real time;

[0008] A spray system for reducing the temperature of the gas cylinders to be stored;

[0009] An exhaust system, which is connected to the exhaust outlet, is used to exhaust gas;

[0010] An alarm system is used to issue an alarm signal to alert personnel;

[0011] A control and display system is installed on the cabinet and is connected to the sensing and monitoring system, the sprinkler system, the exhaust system, and the alarm system to enable real-time control of the exhaust system, the sprinkler system, and the alarm system based on monitoring data.

[0012] By incorporating a cabinet, sensor monitoring system, sprinkler system, ventilation system, alarm system, and control display system, the system enables real-time monitoring of the gas cylinders inside the cabinet and their surrounding environment. This ensures that in the event of gas leaks, external fires, internal depressurization, or other unexpected situations, the system can immediately alert personnel and coordinate with the ventilation and sprinkler systems to handle the emergency, eliminating potential safety hazards and effectively improving the practicality and reliability of the device.

[0013] In some embodiments, the novel fireproof and explosion-proof gas cylinder safety cabinet provided in this application further includes: a door closer, one end of which is disposed on the cabinet wall corresponding to the storage cavity inside the cabinet body, and the other end of which is connected to the side of the cabinet door corresponding to the side near the opening.

[0015] In some embodiments, a manifold is also provided in the storage cavity, and several of the gas cylinders to be stored are connected to an external gas supply pipeline through the manifold, and a pressure reducing device is connected to the manifold.

[0016] By setting up manifolds, the efficiency and flexibility of gas supply can be effectively improved. In addition, the manifolds are equipped with pressure reducing devices, which can reduce the high-pressure gas in the gas cylinder to a suitable pressure level. The manifolds can also precisely control the gas flow rate, thereby effectively ensuring the safe operation of gas-using equipment.

[0017] In some embodiments, the cabinet door is provided with a three-point linkage lock, which includes three locking points. The cabinet door is provided with three movable sides, and the three locking points are respectively provided on the three movable sides.

[0018] By setting up a three-point interlock, the sealing of the cabinet door is effectively enhanced, preventing gas leakage or external fire sources from entering the cabinet. This further improves the safety and reliability of the gas cylinder cabinet. In addition, the three-point interlock can also ensure the formation of a double-person, double-lock mechanism to achieve standardized management of gas cylinders.

[0019] In some embodiments, the sensing and monitoring system includes a combustible gas detector, which is disposed on the cabinet wall corresponding to the exhaust outlet.

[0020] By installing combustible gas detectors on the cabinet walls corresponding to the exhaust outlets, leaked gas is captured as soon as it diffuses through the exhaust outlets, thereby significantly improving the leak detection efficiency and safety reliability of the gas cylinder safety cabinet and providing reliable technical protection for gas storage in high-risk environments.

[0021] In some embodiments, the cabinet includes a base plate, and a trolley flap is connected to the side of the base plate corresponding to the opening via a hinge. The trolley flap is connected to the side wall of the cabinet via a hydraulic device.

[0022] By setting up a trolley flap, it is convenient for the trolley of gas cylinders to enter and exit the storage cabinet. When not in use, this flap has a hydraulic function that can be folded to reduce sparks caused by metal collisions, without taking up other space, further improving the practicality of this device.

[0023] In some embodiments, the exhaust outlet includes an upper exhaust outlet and a lower exhaust outlet. The upper exhaust outlet is located on the top wall of the cabinet, and the lower exhaust outlet is located on the cabinet at the end corresponding to the bottom plate. The alarm system is correspondingly installed on the top wall of the cabinet.

[0024] In some embodiments, the base plate has a hydraulic groove.

[0025] In some embodiments, the cabinet wall includes an outer layer and an inner layer, with a heat insulation layer disposed between the outer layer and the inner layer.

[0026] By incorporating three layers of insulation material, the heat insulation and fire resistance of the cabinet are enhanced, thereby protecting the internal gas cylinders and further improving the fire safety and security performance of the gas cylinder safety cabinet.

[0027] Compared with the prior art, the novel fireproof and explosion-proof gas cylinder safety cabinet provided by this utility model has the following beneficial effects:

[0028] 1. This device, by setting up a cabinet, a sensor monitoring system, a sprinkler system, an exhaust system, an alarm system, and a control and display system, realizes real-time monitoring of the status of gas cylinders inside the cabinet and their surrounding environment. This ensures that in the event of gas leaks, external fires, internal depressurization, or other unexpected situations, the system can immediately alarm to notify personnel and link the exhaust system and sprinkler system to carry out emergency treatment of the unexpected situation, thereby eliminating safety hazards and effectively improving the practicality and reliability of the device.

[0029] 2. This device, by setting a door closer, effectively ensures that the cabinet door is always closed, thereby effectively avoiding safety hazards caused by the cabinet door not being closed due to human negligence, and further improving the safety performance of the gas cylinder cabinet.

An opening is provided on the side wall of the cabinet body 20, and a cabinet door is correspondingly provided at each opening. An exhaust outlet 21 is provided on the cabinet body 20. The sensor monitoring system 30 is located within the storage cavity and is used for real-time monitoring. The system monitors the pressure, temperature, and humidity parameters inside the storage chamber. The spray system 40 is used to reduce the temperature of the gas cylinder 10 to be stored. The exhaust system is connected to the exhaust outlet 21 and is used to exhaust gas. The alarm system 50 is used to issue an alarm signal to remind personnel. The control and display system 60 is installed on the cabinet 20 and is connected to the sensor monitoring system 30, the spray system 40, the exhaust system, and the alarm system 50 to enable real-time control of the exhaust system, the spray system 40, and the alarm system 50 based on the monitoring data.

[0039] Specifically, the cabinet 20 is made of double-layer steel plate, and the cabinet walls are fixedly supported by metal brackets 11. Two gas cylinder placement slots are provided on the brackets 11, facing the opening to ensure convenient placement of the gas cylinders. The sensing and monitoring system 30 includes temperature, pressure, and humidity sensors, which are integrated on the inner wall of the cabinet 20. Additionally, the sprinkler system 40 is connected to an external water source and sprays water onto the storage chamber through sprinkler heads. The sprinkler system 40 typically also includes a coolant supply device to ensure that the sprayed water is cooling water, thereby effectively ensuring the cooling effect and reducing the temperature of the gas cylinders in the event of a fire. The exhaust system is usually located outside the exhaust outlet 21, and the fan can be waterproof.

The control display system 60 is located on the top of the cabinet 20 and includes a touch screen to display temperature, pressure, gas concentration curves and historical data, and to adjust parameters. By combining monitoring parameters such as temperature, pressure and gas concentration, accurate risk assessment can be achieved. At the same time, the control display system 60 can be used to control the sprinkler system 40 and the exhaust system to deal with safety hazards in a timely manner.

[0040] It should be noted that the novel fireproof and explosion-proof gas cylinder safety cabinet provided in this application is not only suitable for laboratories, but also for factory workshops and other places where gas cylinders are needed.

[0041] In one embodiment, refer to the appendix to the specification. Figure 1 and 2 Based on the above embodiments, the novel fireproof and explosion-proof gas cylinder safety cabinet provided in this application also includes a door closer 24. One end of the door closer 24 is disposed on the cabinet wall corresponding to the storage cavity on the cabinet body 20, and the other end of the door closer 24 is connected to the side of the cabinet door corresponding to the opening.

[0042] Specifically, the door closer 24 complies with relevant safety standards such as GA93-2004 to ensure that the door closer 24 can work reliably in emergency situations such as fires, thereby ensuring the safety performance of the gas cylinder cabinet. One end of the door closer 24 is fixed to the inner top wall of the cabinet 20 corresponding to the inner side of the storage cavity, and the other end is connected to the inner side of the cabinet door through a hinge seat. The hinge seat is embedded in the edge of the cabinet door. The hydraulic or spring device of the door closer 24 enables the gas cylinder cabinet door to automatically close to the initial position after opening, thereby effectively avoiding safety hazards caused by human negligence that the cabinet door is not closed, and thus effectively improving the safety and reliability of the overall device.

[0043] In one embodiment, refer to the appendix to the specification. Figure 1 and 2 Based on the above embodiments, a manifold 70 is also provided in the storage cavity, and several gas cylinders 10 to be stored are connected to an external gas supply pipeline through the manifold 70. A pressure reducing device is connected to the manifold 70.

[0044] Specifically, the manifold 70 includes multiple inlets for connecting gas cylinders and an outlet for connecting to an external gas supply system. By concentrating the gas from multiple cylinders through valves and pipes to form a unified gas supply system, the manifold 70 effectively improves the efficiency and flexibility of the gas supply. In addition, the manifold 70 is equipped with a pressure reducing device, which can reduce the high-pressure gas in the cylinders to a suitable operating pressure level. The manifold 70 can also precisely control the gas flow rate, thereby effectively ensuring the safe operation of gas-using equipment. Furthermore, the manifold 70 generally adopts a one-in-one-backup or multiple-in-one-backup configuration. That is, when one set of gas cylinders is used up, it can automatically or manually switch to the backup set, thereby ensuring the continuity and stability of the gas supply. This switching function can effectively reduce gas supply interruptions caused by cylinder replacement, thereby effectively reducing the space occupied by the cylinders, improving the space utilization rate within the storage chamber, and further enhancing the overall reliability of the device.

[0045] In one embodiment, refer to the appendix to the specification. Figure 2 The cabinet door is equipped with a three-point linkage lock 221, which includes three locking points 222. The cabinet door has three movable sides, and the three locking points 222 are respectively located on the three movable sides.

[0046] Specifically, the three-point linkage lock 221 consists of a stainless steel lock body and three sets of linkage bolts. The stainless steel lock body and the three sets of linkage bolts achieve synchronous unlocking and locking actions through a gear linkage mechanism. The three movable sides are correspondingly located on the upper and lower sides of the cabinet door and the side away from the door closer 24. The three sets of linkage bolts are correspondingly located at three locking points 222 on the three movable sides of the cabinet door. The locking points 222 on the upper and lower movable sides are usually located at the edge to ensure a tight engagement, thereby ensuring a secure lock on the cabinet door and effectively preventing lock failure due to external impact or door deformation. The locking point 222 on the movable side away from the door closer 24 is usually located at the midpoint. By setting the three-point linkage lock 221, the sealing performance of the cabinet door is effectively enhanced, preventing gas leakage or external fire sources from entering the cabinet, thereby further improving the safety and reliability of the gas cylinder cabinet.

[0047] In one embodiment, refer to the appendix to the specification. Figure 1 and 2Based on the above embodiments, the sensing and monitoring system 30 includes a combustible gas detector, which is installed on the cabinet wall of the cabinet 20, where an exhaust outlet 21 is provided.

[0048] Specifically, the combustible gas detector can be an explosion-proof combustible gas detector, which is fixed to the side of the exhaust outlet 21 of the cabinet 20 by a fixed bracket. Its probe can be a rotatable probe to adapt to different exhaust outlet 21 directions and leakage path changes, thereby ensuring that the leaked gas is captured as soon as it diffuses through the exhaust outlet 21, thus significantly improving the leakage detection efficiency and safety reliability of the gas cylinder safety cabinet, and providing reliable technical protection for gas storage in high-risk environments.

[0049] In one embodiment, refer to the appendix to the specification. Figure 1 and 2 The cabinet 20 includes a base plate 23. A trolley flap 80 is connected to the side of the base plate 23 near the opening via a hinge. The trolley flap 80 is connected to the side wall of the cabinet 20 via a hydraulic device 90.

[0050] Specifically, the bottom plate 23 of the cabinet 20 is connected to the trolley flap 80 via two double-axis hinges on the side near the opening of the cabinet 20. The hydraulic device 90 is fixed to the side wall of the cabinet 20 via a mounting bracket. By setting the hydraulic device 90, the stability of the trolley flap 80 is also ensured when transporting gas cylinders, thereby ensuring the safety of transporting gas cylinders.

[0051] In one embodiment, refer to the appendix to the specification. Figure 1 and 2 Based on the above embodiments, the exhaust outlet 21 includes an upper exhaust outlet and a lower exhaust outlet. The upper exhaust outlet is located on the top wall of the cabinet 20, and the lower exhaust outlet is located on the end of the cabinet 20 that is close to the bottom plate 23. The alarm system 50 is correspondingly installed on the top wall of the cabinet.

[0052] Specifically, the exhaust outlet 21 includes an upper exhaust outlet and a lower exhaust outlet. The upper exhaust outlet is located at the center of the top wall of the cabinet 20 to discharge leaked rising gas. The lower exhaust outlet is located at one end of the cabinet 20 near the bottom plate 23 to discharge leaked sinking gas. The exhaust outlet 21 is controlled and adjusted by a louvered adjustable air valve and an electric actuator to ensure that when a flammable gas leak occurs in the gas cylinder cabinet, because the gas density in the gas cylinder is less than that of air, the leaked gas diffuses upward along the inner wall of the cabinet, ensuring that the leaked gas gathers at the exhaust outlet 21 as soon as possible and is finally discharged through the area of ​​the exhaust outlet 21. By setting the alarm system 50 on the top wall of the cabinet 20, the visibility of the alarm is improved, further ensuring the alarm's prompting effect.

[0053] In one embodiment, refer to the appendix to the specification. Figure 1 and 2Based on the above embodiments, the bottom plate 23 has a hydraulic groove 231.

[0054] Specifically, the hydraulic tray 231 is equipped with a set of universal wheels to facilitate the daily handling of the gas cylinder cabinet. It also enables the gas cylinder cabinet to be stably placed in a preset position when it is not needed, effectively improving the mobility, safety and adaptability of the gas cylinder safety cabinet.

[0055] In one embodiment, based on the above embodiment, the cabinet wall of the cabinet 20 includes an outer layer and an inner layer, and a heat insulation layer is provided between the outer layer and the inner layer.

[0056] Specifically, the outer layer is preferably made of high-quality galvanized steel sheet, and the inner layer is preferably made of high-temperature resistant aluminum alloy sheet as fireproof and heat-insulating material. The surface is coated with ceramic fireproof coating and there is a heat insulation layer in the middle, which complies with the European standard "EN 14470-2". By setting three layers of heat insulation material, the heat insulation and fireproof performance of the cabinet 20 is enhanced, thereby protecting the internal gas cylinders and further improving the fire protection and safety performance of the gas cylinder safety cabinet.

[0057] Additionally, it should be noted that a document bag 25 is located on the side of the cabinet door near the opening. Document bag 25 can be used to store important documents such as the instruction manual, certificate of conformity, and inspection report of the gas cylinder, allowing users to easily access the basic information and safety requirements of the gas cylinder at any time. It can also be used to record the usage records, filling records, and maintenance records of the gas cylinder, facilitating the traceability and management of the gas cylinder's usage process. The document bag 25 can also contain the gas cylinder's safety operating procedures and precautions, reminding users to follow the correct steps when operating the gas cylinder and avoiding safety accidents caused by improper operation.

[0058] The working principle of this utility model is as follows: When an unexpected situation such as gas leakage, fire or depressurization occurs inside the cabinet 20, the device first detects the abnormal situation through the sensor monitoring system, such as excessively high temperature inside the cabinet 20, excessively high concentration of leaked gas, or excessive pressure. The sensor monitoring system immediately feeds the information back to the control display system 60, which automatically issues an audible and visual alarm and transmits the alarm information to the mobile phone or computer of the management personnel via the network. In addition, the control display system 60 is also linked with the ventilation system, fire extinguishing system, and sprinkler system 40. For example, when a gas leak is detected, the exhaust fan is automatically started to remove the leaked gas in time, and when a fire is detected, the sprinkler system 40 is automatically started to extinguish the fire and cool down the area in time, thereby achieving the effect of automatically eliminating safety hazards and protecting the gas cylinder in time.

[0059] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
