Description

Technical Field

[0001] This invention relates to the field of acetylene cylinder compartment leakage detection technology, and in particular to an acetylene cylinder compartment leakage detection device. Background Technology

[0002] Acetylene, as an important chemical raw material, is widely used in welding, cutting, and other fields. Due to its highly flammable and explosive chemical properties, its storage and transportation require specially designed containers. Ensuring the sealing performance of these containers is a crucial aspect of ensuring the safety of acetylene storage and transportation.

[0003] Currently, commonly used methods for leak detection in acetylene container cells mainly include the water immersion method, the soap water method, and the pressure decay method. Each of these methods has certain limitations. Specifically, the water immersion method requires completely submerging the container in water and identifying the leak location by observing bubbles. This is complex and time-consuming, making it unsuitable for large-scale testing scenarios, and may also cause corrosion or damage to the container surface. The soap water method can only detect localized areas, with limited coverage. Reliance on manual operation leads to low detection efficiency and a tendency to miss potential leaks. The pressure decay method determines the presence of a leak by monitoring changes in the internal pressure of the container, but this method is sensitive to fluctuations in ambient temperature and pressure, easily affected by external conditions, leading to misjudgments or missed detections. Furthermore, these methods generally lack real-time monitoring capabilities, making it impossible to dynamically track leaks. Data recording largely relies on manual labor, which is not only inefficient but also prone to introducing errors, failing to meet the demands of modern chemical storage and transportation industries for efficient and precise management.

[0004] With the gradual adoption of IoT and sensor technologies in industrial inspection, intelligent inspection methods have become an industry trend. However, intelligent leak detection technologies for acetylene container cells are still relatively scarce, and a complete technical solution capable of simultaneously achieving high-precision leak identification, real-time data uploading, and automated operation and maintenance management has not yet been formed. Therefore, there is an urgent need to develop an efficient, accurate, and intelligent acetylene container cell leak detection device and method to improve the safety level and management efficiency of acetylene during storage and transportation. Summary of the Invention

[0005] The purpose of this invention is to provide an acetylene cylinder compartment leakage detection device that achieves efficient, accurate, and intelligent acetylene cylinder compartment leakage detection, thereby improving the safety level and management efficiency of acetylene during storage, transportation, and handling.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An acetylene cylinder compartment leakage detection device includes a detection chamber body, an acetylene gas detector, a weighing sensor, a wireless communication module, and a cloud platform;

[0008] The weighing sensor is installed at the bottom inside the testing chamber to support the acetylene cylinder compartment and measure the weight of the acetylene cylinder compartment in real time.

[0009] Acetylene gas detectors are distributed and installed at key leak points in the acetylene cylinder compartments inside the detection chamber to measure acetylene gas concentration data in real time.

[0010] The weight data and acetylene gas concentration data of the acetylene cylinder compartment together constitute the acetylene cylinder compartment leakage detection data; the wireless communication module is used to collect the acetylene cylinder compartment leakage detection data and timestamp information and upload them to the cloud platform;

[0011] The cloud platform is used to receive, store, and process the acetylene cylinder compartment leakage detection data and timestamp information uploaded by the wireless communication module, and generate acetylene cylinder compartment alarm signals or acetylene cylinder compartment safety status analysis reports.

[0012] As one possible approach, the testing chamber is constructed from welded steel plates with an internal anti-corrosion coating. A viewing window made of tempered glass is located on the side of the chamber. A roller shutter door is located on the front of the chamber, driven by a motor to open and close. The opening and closing time of the roller shutter door is controlled to within 5 seconds.

[0013] As one possible approach, the acetylene gas detector has an electrode coated with a catalyst inside, and the output is electrically connected to an amplifier circuit; the catalyst is for the electrochemical reaction of acetylene gas, and the electrode is designed to be detachable.

[0014] When acetylene gas comes into contact with the electrode, an electrochemical reaction occurs, generating a current signal proportional to the acetylene gas concentration. After being processed by the amplification circuit, this signal is converted into the acetylene gas concentration. The detection limit of the acetylene gas detector is 1 ppm.

[0015] There are multiple acetylene gas detectors, which are distributed and installed at the corresponding key leak points in the acetylene cylinder container inside the detection room, forming an acetylene gas concentration monitoring network covering the entire area of ​​the acetylene cylinder container.

[0016] A display is located on the inner side of the testing chamber, opposite the viewing window; the wireless communication module is also used to send the collected acetylene gas concentration data to the display; the display is used to receive and display the acetylene gas concentration data sent by the wireless communication module.

[0017] One possible implementation is a strain gauge alloy steel load cell with a multi-point support structure, a measurement range of 0 to 2000 kg, and a resolution of 0.1 kg; the surface of the load cell is nickel-plated.

[0018] The top of the weighing sensor is fixed with a limit module by bolts; the limit module is made of metal and has a rectangular frame structure, which is used to fix the position of the acetylene cylinder container and eliminate weighing errors caused by external vibration or tilting; the inner side of the frame of the limit module has a guide groove with a polished surface, which is used to guide the positioning of the manipulator arm of the manual forklift or forklift robot.

[0019] The output terminal of the weighing sensor is electrically connected to a signal conditioning circuit; the output signal of the weighing sensor is a millivolt-level voltage signal that is proportional to the weight of the acetylene cylinder compartment. This millivolt-level voltage signal is processed by the signal conditioning circuit and converted into the weight of the acetylene cylinder compartment.

[0020] The wireless communication module is also used to send the collected acetylene cylinder compartment weight data to the display; the display is used to receive and display the acetylene cylinder compartment weight data sent by the wireless communication module.

[0021] As one possible approach, the wireless communication module supports three communication methods: 4G, 5G and WiFi. It is used to collect acetylene gas concentration data, acetylene cylinder container weight data and timestamp information and upload them to the cloud platform.

[0022] The wireless communication module has a built-in encryption algorithm to encrypt and protect transmitted data.

[0023] After receiving the data, the cloud platform uses a preset analysis model to dynamically monitor the changes in acetylene gas concentration and the weight of the acetylene cylinder compartment, and generates an alarm signal or a safety status assessment report for the acetylene cylinder compartment.

[0024] As one possible approach, the cloud platform stores and processes the acetylene cylinder compartment leakage detection data and timestamp information uploaded by the wireless communication module, uses time series algorithms to identify the changing trends of acetylene gas concentration and acetylene cylinder compartment weight, and generates acetylene cylinder compartment alarm signals by combining historical data.

[0025] When the acetylene gas concentration exceeds the preset threshold or the weight of the acetylene cylinder compartment changes abnormally, the cloud platform generates an alarm signal for the acetylene cylinder compartment and notifies the relevant management personnel via SMS or email.

[0026] As one possible approach, the cloud platform is deployed on a distributed server cluster and employs load balancing technology; the user interface of the cloud platform supports access from multiple terminals, including PCs and mobile devices.

[0027] As one feasible approach, the acetylene cylinder container leak detection device is equipped with a main power system and a backup power system. The backup power system uses a lithium-ion battery pack as an energy storage unit with a capacity of 2000mAh, enabling the device to operate for at least 2 hours in the event of a power outage in the main power system.

[0028] As one possible approach, cloud platforms and external warehouse management systems interact with each other via standard interface protocols.

[0029] Based on the safety status assessment report of the acetylene cylinder container provided by the cloud platform, the warehouse management system automatically plans the storage and retrieval path of the forklift robot for the acetylene cylinder container; based on the alarm signal of the acetylene cylinder container provided by the cloud platform, the warehouse management system triggers the emergency response mechanism to isolate the problematic acetylene cylinder container to a designated area.

[0030] As one possible approach, the warehouse management system binds the unique identification information of the acetylene cylinder container to an RFID tag; the RFID tag is installed in a fixed position on the outer shell of the acetylene cylinder container, with a reading and writing distance of 0 to 10 centimeters.

[0031] Beneficial technical effects of the present invention:

[0032] The acetylene cylinder compartment leak detection device of this invention achieves real-time monitoring of acetylene cylinder compartment leaks through a high-sensitivity acetylene gas detector layout, significantly improving the efficiency and accuracy of acetylene cylinder compartment leak detection. By combining a weighing sensor and a wireless communication module, it enables dynamic monitoring of acetylene gas usage and remote data transmission, facilitating timely monitoring of acetylene gas consumption by management personnel. The limit module design simplifies the storage and retrieval operation process for forklift robots, improving inbound and outbound efficiency. Through integration with a warehouse management system, it achieves fully automated management from detection to processing, providing enterprises with an intelligent solution.

[0046] See Figure 1-6 This embodiment provides an acetylene cylinder compartment leakage detection device, the core of which lies in the intelligent and automated management of acetylene cylinder compartment leakage detection through the coordinated work of an acetylene gas detector, a weighing sensor, a wireless communication module, a cloud platform, and a limit module, combined with a warehouse management system.

[0047] In this embodiment, the acetylene cylinder container leakage detection device includes a detection chamber body 1, an acetylene gas detector, a weighing sensor 5, a wireless communication module 7, and a cloud platform 10.

[0048] The weighing sensor 5 is installed at the bottom inside the main body 1 of the testing chamber to support the acetylene cylinder compartment 11 and measure the weight data of the acetylene cylinder compartment in real time.

[0049] Acetylene gas detectors are distributed and installed at the critical leak points of acetylene gas cylinder compartments 11 inside the main body of the detection chamber 1, for real-time measurement of acetylene gas concentration data.

[0050] The weight data and acetylene gas concentration data of the acetylene cylinder compartment together constitute the acetylene cylinder compartment leakage detection data; the wireless communication module 7 is used to collect the acetylene cylinder compartment leakage detection data and timestamp information and upload them to the cloud platform 10; the data acquisition frequency of the wireless communication module 7 is once per second.

[0051] The cloud platform 10 is used to receive, store, and process the acetylene cylinder compartment leakage detection data and timestamp information uploaded by the wireless communication module 7, and generate acetylene cylinder compartment alarm signals or acetylene cylinder compartment safety status analysis reports.

[0052] In this embodiment, the detection chamber body 1 is the core load-bearing structure of the entire device. It is welded from steel plates and coated with an anti-corrosion coating inside, which can adapt to the highly corrosive environment of acetylene gas.

[0053] The side of the testing chamber body 1 is provided with a viewing window 2. The viewing window 2 is made of tempered glass material with a thickness of 8 mm. It has good light transmission and impact resistance, making it convenient for operators to observe the internal conditions of the testing chamber body 1.

[0054] The front of the testing chamber body 1 is equipped with a roller shutter door 3, which is driven by a motor to open and close. Opening the roller shutter door 3 opens the testing chamber body 1, making it easy for operators to place the acetylene cylinder container 11 onto the weighing sensor 5 at the bottom of the testing chamber body 1. Closing the roller shutter door 3 closes the testing chamber body 1, creating a closed environment for acetylene cylinder container leakage detection inside the testing chamber body 1. The opening and closing time of the roller shutter door 3 is controlled within 5 seconds to ensure the high efficiency of the acetylene cylinder container leakage detection process.

[0055] In this embodiment, the wireless communication module 7 and the cloud platform 10 can be installed inside the testing room body 1 or outside the testing room body 1.

[0056] In this embodiment, the acetylene gas detector has an electrode coated with a catalyst inside, and the output terminal is electrically connected to an amplifier circuit.

[0057] The catalyst is a catalyst for the electrochemical reaction of acetylene gas, preferably one of a noble metal catalyst or a metal oxide catalyst, more preferably platinum, palladium or their alloys; the electrode has a service life of 5 years and the electrode is detachable, so that the acetylene gas detector can be quickly maintained by replacing the electrode;

[0058] The working principle of the acetylene gas detector is based on electrochemical sensor technology. When acetylene gas comes into contact with the electrode, an electrochemical reaction occurs, generating a current signal that is proportional to the acetylene gas concentration. After being processed by the amplification circuit, the signal is converted into the acetylene gas concentration. The detection limit of the acetylene gas concentration of the acetylene gas detector is 1 ppm.

[0059] There are multiple acetylene gas detectors, which are distributed and installed at the corresponding locations of key leak points in the acetylene cylinder container 11 inside the main body of the detection room 1, forming an acetylene gas concentration monitoring network covering the entire area of ​​the acetylene cylinder container 11.

[0060] On the inner side of the detection chamber body 1, a display 4 is provided opposite to the viewing window 2; the wireless communication module 7 is also used to send the collected acetylene gas concentration data to the display 4; the display 4 is used to receive and display the acetylene gas concentration data sent by the wireless communication module 7, and the operator can view the acetylene gas concentration data displayed on the display 4 through the viewing window 2 which is set opposite to the display 4.

[0061] In this embodiment, the weighing sensor 5 is a strain gauge alloy steel weighing sensor with a multi-point support structure. The multi-point support structure enables accurate measurement of the weight of the acetylene cylinder container, with a measurement range of 0 to 2000 kg and a resolution of 0.1 kg. The surface of the weighing sensor 5 is nickel-plated to enhance its corrosion resistance.

[0062] The weighing sensor 5 is equipped with a limit module 6 on its top. The limit module 6 is made of metal material and has high strength and deformation resistance. It is used to fix the position of the acetylene cylinder container 11 and eliminate weighing errors caused by external vibration or tilting.

[0063] The output terminal of the weighing sensor 5 is electrically connected to a signal conditioning circuit; the output signal of the weighing sensor 5 is a millivolt-level voltage signal that is proportional to the weight of the acetylene cylinder container. This millivolt-level voltage signal is processed by the signal conditioning circuit and converted into the weight of the acetylene cylinder container.

[0064] The wireless communication module 7 is also used to send the collected acetylene cylinder container weight data to the display 4; the display 4 is used to receive and display the acetylene cylinder container weight data sent by the wireless communication module 7. The operator can view the acetylene cylinder container weight data displayed on the display 4 through the window 2 set opposite to the display 4.

[0065] In this embodiment, the limiting module 6 is fixed to the top of the weighing sensor 5 by bolts;

[0066] The limiting module 6 has a rectangular frame structure, and the inner side of the frame is provided with a guide groove 9, which is used to guide the manipulator arm of the manual forklift or forklift robot to be accurately positioned.

[0067] The guide groove 9 is 10 cm wide and 10 cm deep, and its surface is polished to reduce friction while ensuring the stability of the manual forklift or forklift robot arm.

[0068] The design of limit module 6 simplifies the storage and retrieval operation process of the forklift robot, improves the efficiency of entering and leaving the warehouse, and avoids damage or leakage of acetylene cylinders due to malfunctions.

[0069] The limiting module 6 has a rectangular frame structure, designed to limit the four-way offset of the acetylene cylinder container. If there are slight errors during placement, the limiting module 6 can rigidly correct them, eliminating the need for manual forklifts and AGVs for precise alignment. It also prevents collisions with the positioning detectors during placement. Therefore, this device improves placement accuracy, reduces calibration time, and increases efficiency.

[0070] In this embodiment, the wireless communication module 7 supports three communication methods: 4G, 5G and WiFi, and is used to collect acetylene gas concentration data, acetylene cylinder container weight data and timestamp information and upload them to the cloud platform 10.

[0071] The wireless communication module 7 has a built-in encryption algorithm to protect the transmitted data and prevent the data from being leaked or tampered with.

[0072] After receiving the data, the cloud platform 10 uses a preset analysis model to dynamically monitor the changes in acetylene gas concentration and the weight of the acetylene cylinder compartment, and generates an acetylene cylinder compartment alarm signal or an acetylene cylinder compartment safety status assessment report.

[0073] In this embodiment, the preset analysis model uses a gas detector to detect the acetylene gas concentration and weight of the acetylene cylinder container before it is put into storage, the acetylene gas concentration and weight of the acetylene cylinder container before it is taken out of storage, and the acetylene gas concentration and weight of the acetylene cylinder container when the empty cylinder is returned to storage. The model then compares the maximum, minimum and average values ​​in the database to generate a safety status assessment report.

[0074] In this embodiment, the cloud platform 10 stores and processes the acetylene cylinder compartment leakage detection data and timestamp information uploaded by the wireless communication module 7, uses a time series algorithm to identify the changing trends of acetylene gas concentration and acetylene cylinder compartment weight, and generates an acetylene cylinder compartment alarm signal by combining historical data.

[0075] When the acetylene gas concentration exceeds the preset threshold or the weight of the acetylene cylinder compartment changes abnormally, the cloud platform 10 generates an acetylene cylinder compartment alarm signal and notifies the relevant management personnel via SMS or email.

[0076] In this embodiment, the cloud platform 10 is deployed on a distributed server cluster, and high-concurrency data processing capability is achieved through load balancing technology;

[0077] The user interface of the cloud platform 10 supports access from multiple terminals, including PCs and mobile devices. Users can view acetylene cylinder compartment leakage detection data, acetylene cylinder compartment alarm information, and acetylene cylinder compartment safety status assessment reports through a browser or corresponding application.

[0078] In this embodiment, the acetylene container leak detection device is equipped with a main power system and a backup power system; the backup power system uses a lithium-ion battery pack as an energy storage unit with a capacity of 2000mAh, which can maintain the device operation for at least 2 hours in the event of a power outage of the main power system.

[0079] In this embodiment, the cloud platform 10 and the external warehouse management system 8 interact with each other through a standard interface protocol to ensure seamless connection between the acetylene cylinder container leakage detection data of the cloud platform 10 and the inventory management information of the warehouse management system 8.

[0080] Based on the safety status assessment report of the acetylene cylinder container provided by the cloud platform 10, the warehouse management system 8 automatically plans the storage and retrieval path of the forklift robot for the acetylene cylinder container; based on the alarm signal of the acetylene cylinder container provided by the cloud platform 10, the warehouse management system 8 triggers the emergency response mechanism to isolate the problematic acetylene cylinder container to a designated area.

[0081] In this embodiment, the safety status assessment report is generated based on parameters such as the leakage amount and weight of the acetylene cylinder container, and the content is displayed as safe, risky, low leakage, or high leakage. If the content is displayed as safe, the process continues to the next step; if the content is displayed as risky, the process is exited for leak point sealing and repair or temporary storage; if the content is displayed as low leakage or high leakage, the product is directly returned to the supplier. Based on this judgment, the AGV's travel route is different for each case, all of which are automated processes generated by the system.

[0082] In this embodiment, the warehouse management system 8 binds the unique identification information of the acetylene cylinder container 11 to an RFID tag; the RFID tag includes the following information: the production batch, filling time and gas type of the acetylene cylinder container 11;

[0083] The RFID tag is installed in a fixed position on the outer shell of the acetylene cylinder container 11, with a reading and writing distance of 0 to 10 centimeters to ensure the accuracy of RFID tag information reading.

[0084] In this embodiment, the overall design of the acetylene cylinder compartment leakage detection device follows the modular principle. The functional modules are connected through standardized interfaces, which facilitates maintenance and upgrades. For example, the power supply modules of the acetylene gas detector 4 and the weighing sensor 5 are designed independently and support hot-swapping operations, which can be replaced without affecting the operation of other modules.

[0085] Using the above-mentioned acetylene container leak detection device to perform acetylene container leak detection includes the following steps:

[0086] Step 1: Place the acetylene cylinder container 11 inside the detection chamber body 1, and close the roller shutter door 3 to create a closed acetylene cylinder container leakage detection environment inside the detection chamber body 1.

[0087] Step 2: Activate acetylene gas detector 4 and weighing sensor 5 to measure acetylene gas concentration data and acetylene cylinder container weight data respectively;

[0088] Step 3: The wireless communication module 7 collects acetylene gas concentration data, acetylene cylinder container weight data and timestamp information and uploads them to the cloud platform 10;

[0089] Step 4: The cloud platform 10 stores and processes the received acetylene gas concentration data, acetylene cylinder container weight data and timestamp information, determines whether there is a risk of leakage in the acetylene cylinder container 11, and generates an acetylene cylinder container alarm signal or an acetylene cylinder container safety status assessment report.

[0090] Step 5: The cloud platform 10 and the warehouse management system 8 work together; based on the safety status assessment report of the acetylene cylinder container provided by the cloud platform 10, the warehouse management system 8 automatically plans the storage and retrieval path of the forklift robot for the acetylene cylinder container; based on the alarm signal of the acetylene cylinder container provided by the cloud platform 10, the warehouse management system 8 triggers the emergency response mechanism to isolate the problematic acetylene cylinder container to a designated area.

[0091] The acetylene cylinder compartment leak detection device in this embodiment, through a high-sensitivity acetylene gas detector layout, achieves real-time monitoring of acetylene cylinder compartment leaks, significantly improving the efficiency and accuracy of acetylene cylinder compartment leak detection. The combination of a weighing sensor and a wireless communication module enables dynamic monitoring of acetylene gas usage and remote data transmission, facilitating timely monitoring of acetylene gas consumption by management personnel. The limit module design simplifies the storage and retrieval operation process for forklift robots, improving inbound and outbound efficiency. Through integration with the warehouse management system, it achieves fully automated management from detection to processing, providing enterprises with an intelligent solution.

[0092] The acetylene container leak detection device in this embodiment features an acetylene gas detector equipped with a high-sensitivity electrochemical sensor with a lower limit of 1ppm. The sensor is installed through a viewing window covering the entire area, and its replaceable electrodes balance accuracy and ease of maintenance. A strain gauge-type alloy steel weighing sensor, linked to a limit module, eliminates errors and accurately captures changes in leak weight. Employing a "local acquisition + cloud analysis" architecture, it uses dual-mode communication for high-frequency data transmission, and a cloud-based early warning model identifies risks in advance. The automated detection process is linked to the warehouse management system, reducing emergency response time to 5 minutes and eliminating manual intervention. It also features modular design and environmental adaptability from -20℃ to 50℃, among other special functional requirements. The optimized structure of the detection chamber and limit module enhances efficiency and safety.
