Description

Technical Field

[0001] The invention relates to the technical field of gas cylinder storage cabinets, in particular to a safety explosion-proof cabinet for gas cylinders. Background Art

[0002] Medical gases (such as oxygen, carbon dioxide, and nitric oxide) are core resources for medical treatment, surgical procedures, and equipment operation. Their storage safety directly impacts clinical reliability. Traditionally, medical cylinders are stored in explosion-proof cabinets and rely on manual handling and securing. Operators use cylinder carts to transport the cylinders to the cabinet, manually adjust their position, and secure them with steel chains. However, this method has significant drawbacks: 1. Cylinders are large and heavy, creating significant friction between the cabinet bottom and the cylinders. Manual movement can cause them to slip or become stuck, making handling laborious and posing a risk of tipping. 2. Traditional anti-tip structures often utilize rigid steel frames or steel chains. The rigid contact between the cylinder and the frame can easily cause surface coating wear, scratches, and even localized dents. Long-term use can accelerate corrosion and shorten the lifespan of the cylinders. 3. Management relies on manual inspections, making it difficult to promptly detect abnormal temperature and humidity within the cabinet, gas leaks, or fire hazards. Emergency response relies on empirical judgment, resulting in a high response lag. Therefore, there is an urgent need for a new type of safety explosion-proof cabinet that integrates assisted movement, flexible fixation, precise environmental control and cloud-based collaborative management to solve the problems of high operational risks, large equipment losses and low management efficiency in the storage of medical cylinders.

DETAILED DESCRIPTION

[0027] See also Figure 1-Figure 2 A gas cylinder safety explosion-proof cabinet of the present invention includes a cabinet body 1, a cabinet door 2, a cylinder moving device 3, a cylinder fixing device 4, an environmental adjustment device 5, a sensor module, a control module, a communication module and a power module.

[0028] The front of the cabinet body 1 is hinged with a double-opening cabinet door 2, which can be sealed to the cabinet body 1. The cabinet body 1 and cabinet door 2 can be made of double-layer cold-rolled steel plates. The interlayer between the cabinet body 1 and the cabinet door 2 is filled with flame-retardant and heat-insulating materials such as ceramic fiber to enhance the structural stability of the cabinet body 1 and improve explosion resistance and temperature control. The interior and exterior surfaces of the cabinet body 1 and cabinet door 2 are sprayed with epoxy resin powder to improve corrosion resistance and antistatic properties.

[0029] The steel cylinder moving device 3 and the steel cylinder fixing device 4 are both fixedly arranged in the cabinet 1. The steel cylinder moving device 3 is used to assist in moving and fixing the steel cylinder.

[0030] See also Figure 3-Figure 7The cylinder fixing device 4 can be provided with multiple groups to store the same number of cylinders as the cabinet body 1, that is, one cylinder corresponds to one cylinder fixing device 4. The cylinder fixing device 4 includes a fixing plate 41 fixed to the rear cabinet panel of the cabinet body 1. The front side of the fixing plate 41 is an arcuate opening adapted to the surface shape of the cylinder and is provided with an air ring mounting groove. The arc-shaped air ring 42 is fixedly embedded in the air ring mounting groove. The arc-shaped air ring 42 in this embodiment can be pre-inflated by an external inflation device during assembly or inflated in conjunction with the cylinder moving device 3 to expand it. The linkage inflation will be further explained later. A strap mounting groove 43 is provided inside the fixing plate 41. The strap mounting groove 43 includes a receiving portion 43.1 and an extension portion 43.2. The receiving portion 43.1 is connected to the extension portion 43.2. The extension portion 43.2 is arranged close to the left side of the fixing plate 41 and is connected to the outside. A rotating shaft 44 is fixedly mounted at the center of the storage portion 43.1. A winding drum 45 is rotatably mounted on the rotating shaft 44. The winding drum 45 is a cylindrical body with an I-shaped cross-section, one end of which is closed and has a retaining hole for the rotating shaft 44 to pass through. A spring 46 is mounted on the outer periphery of the rotating shaft 44 and housed within the winding drum 45. The ends of the spring 46 are respectively fixedly connected to the outer wall of the rotating shaft 44 and the inner wall of the winding drum 45. A strap 47 is wound around the outer wall of the winding drum 45. One end of the strap 47 is fixedly connected to the outer wall of the winding drum 45. The other end of the strap 47 extends outward from the extension portion 43.2 and is fixedly mounted with a hook 48. A hook ring 49 is fixedly mounted on the front right side of the fixing plate 41 to engage with the hook 48. In order to fix the strap, a fixed clamping block 411 and a movable clamping block 412 are further symmetrically provided on both sides of the extension portion 43.2. The fixed clamping block 411 is fixedly connected to the right side of the extension portion 43.2. A movable groove 410 connected to the outside is provided on the left side of the extension portion 43.2. The movable groove 410 is divided into a clamping block accommodating portion 410.1, a connecting rod portion 410.2, a fixed portion 410.3 and a movable portion 410.4 from right to left. The movable clamping block 412 can be movably arranged in the clamping block accommodating portion 410.1. The left side of the movable clamping block 412 is fixedly connected with a push rod 413. The push rod 413 passes through the connecting rod portion 410.2, the fixed portion 410.3 and the movable portion 410.4 in sequence and extends to the outside, and is fixedly connected with a knob head 413.1 and a card 413.2. The movable portion 410.4 and the card 413.2 are adapted to be rectangular in shape. The fixed portion 410.3 is a circular groove, and its thickness is slightly wider than that of the card 413.2. The opposite surfaces of the fixed clamping block 411 and the movable clamping block 412 are bonded with an anti-slip rubber layer.

[0031] During use, the hook 48 is pulled out to hook the hook ring 49, and the push rod 413 is pushed to move the movable clamping plate 412 to the right, thereby clamping the strap 47 together with the fixed clamping block 411. At the same time, the card 413.2 passes through the movable portion 410.4 to the fixed portion 410.3, and then the push rod 413 is rotated. The push rod 413 and the movable portion 410.4 form a spatial cross and are locked in the fixed portion 410.3, thereby restricting the movement of the movable clamping plate 412. The strap 47 can no longer be pulled, and the middle of the cylinder is fixed, preventing it from tipping. When the hook 48 is released, the winding drum 45 rotates under the reset action of the spring 46, and the strap 47 is automatically wound and retracted into the fixed plate 41. This improves the convenience of operation and solves the problem of the steel chain not being fixed tightly enough and easily damaging the surface of the cylinder.

[0032] See also Figure 8-Figure 9 The cylinder moving device 3 includes a mounting base 31. The upper surface of the mounting base 31 is provided with a plurality of U-shaped grooves 32. Multiple groups of U-shaped grooves 32 can be provided corresponding to the cylinder fixing device 4, that is, one U-shaped groove 32 is placed corresponding to each cylinder. The U-shaped grooves 32 are provided with a plurality of air grooves 33. A gas pressure column 35 is movably inserted into the air groove 33. The outer periphery of the gas pressure column 35 is symmetrically provided with a protrusion 35.1. The center of the protrusion 35.1 is provided with a through hole. The inner wall of the air groove 33 is symmetrically provided with a limit groove 34. A movable rod 36 is fixedly provided in the limit groove 34. The movable rod 36 passes through the through hole so that the protrusion 35.1 can be movably sleeved on the outside of the movable rod 36 and embedded in the limit groove 34. A spring 37 is provided on the outer sleeve of the movable rod 36, and the two ends of the spring 37 are respectively fixed to the bottom of the protrusion 35.1 and the limit groove 34. A cylinder 38 is fixedly mounted at the bottom of the air groove 33. A branch pipe 39 is connected below the cylinder 38. Multiple branch pipes 39 within the same U-shaped groove 32 are connected to one end of a main pipe 310, the other end of which is connected to the air inlet of the arc-shaped air ring 42. When the spring 37 is in its natural state, the portion of the air pressure column 35 extending from the air groove 33 is in the shape of an inclined column, with a ball socket defined at its top. A ball 35.2 is movably embedded within the socket. Ball 35.2 can be made of a relatively hard rubber material with a polished surface. The inner wall of the socket is coated with a smooth material, such as Teflon, to reduce the ball's rotational resistance. A plug body 35.3 is fixedly provided at the bottom of the air pressure column 35, and the plug body 35.3 can be movably inserted into the cylinder 38, and a sealing rubber ring is fixedly provided on the circumference of the plug body 35.3 to ensure that the plug body 35.3 and the cylinder 38 are sealed and the entire air chamber is formed from the branch pipe 39 to the main pipe 310. The air chamber is pre-filled with gas in the initial state, and the amount of pre-filled gas cannot cause the arc-shaped air ring 42 to expand.

[0033] When placing a cylinder, the operator aligns the cylinder cart with the U-shaped groove 32 and presses against the top of the mounting seat 31. The cylinder is moved so that it presses against the air pressure column 35. The air pressure column 35, in contact with the cylinder, moves downward along the air groove 33, forming a concave support structure that acts as a circumferential limit for the bottom of the cylinder, preventing involuntary movement. When the cylinder is pushed, the rolling friction between the bottom of the cylinder and the contacting sphere 35.2 causes the sphere 35.2 to rotate, allowing the cylinder to move easily on the air pressure column 35, thus solving the problem of difficult movement when placed flat. As the air pressure column 35 moves downward, the plug 35.3 at its bottom moves downward along the cylinder 38. The gas in the air chamber is squeezed by external force and transported from the branch pipe 39 to the main pipe 310 to the arc-shaped balloon 42, inflating the arc-shaped balloon 42 and causing it to expand. The expanded arc-shaped balloon 42 contacts the cylinder, preventing damage to the cylinder from rigid contact with the fixed bracket and extending the service life of the cylinder.

[0034] The sensor module is used to collect environmental data inside the cabinet 1. It includes a temperature sensor, a humidity sensor, a gas concentration sensor and a smoke sensor. The temperature sensor and the humidity sensor are used to monitor the temperature and humidity inside the cabinet 1. The gas concentration sensor is used to detect the gas concentration inside the cabinet 1 to determine whether the cylinder is leaking. The smoke sensor is used to detect the smoke concentration inside the cabinet 1 to determine whether there is a fire source inside the cabinet 1.

[0035] The environmental conditioning device 5 is used to maintain the environmental data in the cabinet 1 within a preset range, ensuring that the cylinders are stored under good environmental conditions. The environmental conditioning device 5 is selected according to the corresponding sensor module, and includes a refrigeration unit, a heating unit, a dehumidification unit, and a ventilation unit. The refrigeration unit and the heating unit are used to regulate the cabinet 1 and respectively perform cooling and heating operations on the cabinet 1. The dehumidification unit can dehumidify the cabinet 1, and the ventilation unit can ventilate the cabinet 1. For example, the refrigeration unit uses semiconductor refrigeration chips for ventilation and cooling, the heating unit uses electric heating wires for ventilation and heating, and the dehumidification unit uses a dehumidifier. In fact, the refrigeration unit, heating unit, dehumidification unit, and ventilation unit can be selected from a variety of products on the market, so they are not specifically limited in this embodiment.

[0036] The control module includes a PLC controller, a display screen, and an alarm. The display screen, sound and light alarm, sensor module, communication module, and power module are all electrically connected to the PLC controller. The display screen is used to display real-time temperature, humidity, gas concentration, and smoke concentration data within the cabinet 1. The alarm is located outside the cabinet 1 and is independently configured for each type of environmental data. It includes an LED alarm and a sound and light alarm. The LED alarm and sound and light alarm are set with different colored indicator lights according to the environmental data to provide different warnings. The PLC controller is configured as follows: a. Collect environmental data from the sensor module and compare it with preset thresholds. The preset thresholds include the temperature range thresholds set in the PLC controller's internal program, as well as the thresholds for humidity, gas concentration, and smoke concentration. The temperature thresholds include high and low temperature thresholds.

[0037] b. Continuously collect temperature, humidity, gas concentration and smoke concentration data. When one of the environmental data exceeds the threshold, the environmental adjustment device is triggered to start adjustment and generate a graded alarm signal. The display screen is controlled to display a warning sign and the alarm is turned on according to the graded alarm signal.

[0038] c. The environmental data and graded alarm signals are transmitted to the gateway through the communication module. The gateway communicates with the cloud server, and the cloud server communicates with the mobile terminal and exchanges data.

[0039] The cloud server, built on a cloud platform, integrates a systematic management model with integrated data collection, storage, and analysis capabilities, forming a big data analytics platform that supports distributed information processing. This platform integrates an explosion-proof cabinet safety monitoring system accessible from mobile terminals. This system, leveraging the cloud server's database architecture, comprises two core modules: a cloud storage system and a cloud publishing system. It features historical data backtracking, real-time status monitoring, visual analysis of sensor data trends, abnormal status warnings, and environmental parameter out-of-limit alarms. Staff access the cloud server via mobile terminals connected to the wireless network, obtaining real-time information on the explosion-proof cabinet's operating status, environmental data, and dynamic alarms. This enables collaborative management of data interaction and timely responses throughout the entire process.

[0040] The graded alarm signals include minor and major alarms. Minor alarms display a warning sign on the display, activate an LED alarm light, and send a message to staff via the communication module. Major alarms display a warning sign on the display, activate an audible and visual alarm, and send a message to staff via the communication module. Examples of LED alarm lights include green and blue LEDs, while examples of audible and visual alarms include yellow and red LEDs.

[0041] The communication module may be a wireless communication module, such as a 4G / 5G or Wi-Fi communication module.

[0042] The power module is used to supply power to each module. It includes a mains power interface and a backup battery. The backup battery is configured to automatically switch when the mains power is interrupted to ensure uninterrupted operation of the explosion-proof cabinet.

[0043] Environmental adjustment process in cabinet 1 and corresponding alarm status: 1. When the temperature data reaches the high temperature threshold or the low temperature threshold, the PLC controller will control the refrigeration unit or the heating unit to input cold air or warm air into the cabinet 1. The temperature data on the on-site display screen will be marked in red and a green light alarm will be issued. At the same time, a "temperature too high / temperature too low" message will be issued to the staff.

[0044] 2. When the humidity data reaches the humidity threshold set in the program, the PLC controller will control the dehumidification unit to perform dehumidification operation on cabinet 1. The humidity data on the on-site display screen will be marked in red and a blue light alarm will be issued. At the same time, a "humidity is too high" message will be sent to the staff to remind them.

[0045] 3. When the gas concentration data reaches the gas concentration threshold set in the program, the PLC controller will control the ventilation unit to suck and discharge the gas in cabinet 1 and input external air, while keeping the excess gas concentration data less than 5% to avoid excessive leakage of gas concentration in cabinet 1. If the concentration of flammable gas is too high, it is very easy to cause an explosion. The gas concentration data on the on-site display screen is marked in red and an audible and visual alarm such as a yellow light is issued. At the same time, a "gas concentration is too high" message is issued to the staff to remind them to check for cylinder leakage in time.

[0046] 4. When the smoke concentration data reaches the gas concentration threshold set in the program, the smoke concentration data on the on-site display screen will be marked in red and a red light sound and light alarm will be issued. At the same time, a "smoke concentration is too high" message will be sent to the staff to remind them to check the cabinet 1 and the storage of the cylinders in time.
