Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical accident handling simulation training, and in particular to a multifunctional leak-stopping simulation training device. Background Technology

[0002] With the rapid development of my country's economy, the country's chemical industry has also achieved significant progress. The amount of hazardous chemicals used in production, operation, storage, and transportation is constantly increasing. Due to the flammable, explosive, toxic, and corrosive properties of hazardous chemicals, as well as the special characteristics of the environments they are in, such as high temperatures and high pressures, accidents involving hazardous chemicals are highly likely and extremely dangerous. Once a leak occurs, it not only causes significant loss of life and property but also easily leads to severe environmental pollution and damage.

[0003] In the handling of hazardous chemical spills, plugging and sealing the leak is a crucial measure and method for eliminating the hazard. Choosing appropriate plugging tools and methods can achieve twice the result with half the effort. However, plugging operations are difficult, dangerous, and technically demanding, and professional rescue forces lack practical experience. Therefore, there is an urgent need to utilize simulation training devices to conduct systematic practical training to improve the ability to handle hazardous chemical accidents.

[0004] Currently, overseas leak sealing simulation training mainly relies on chemical plant simulation facilities or abandoned tank trucks to conduct targeted training. Rescue personnel can quickly familiarize themselves with chemical production processes and the internal structure of tank trucks, but the simulated scenarios are limited, and the types of leaked media are few, making it insufficient to handle most leak accident scenarios.

[0005] Domestic leak-sealing simulation training devices typically combine miniature chemical equipment to simply simulate common leak locations in leak accidents. However, these devices differ significantly in size from the targets in real leak accidents, failing to meet the requirements of realistic training. Researchers at the Shanghai Fire and Rescue Research Institute designed modular, multi-functional pressurized leak-sealing simulation training devices using actual hazardous chemical tank trucks as carriers. These devices offer advantages such as centralized on-site automatic control and wireless remote automatic control, achieving the requirements of realistic and standardized leak-sealing training. However, the leaking medium cannot reach a high-temperature state, which is inconsistent with reality. Other scholars have improved and innovated leak-sealing simulation training devices, designing controllable leak outlets to increase the randomness and controllability of leak-sealing training; designing leak-sealing training scoring systems to evaluate leak-sealing effectiveness and reduce errors in evaluation based on direct observation or experience; some training devices use water as the leaking medium, which cannot simulate gas leaks; some use pressurized gas cylinders or steam to simulate pressurized leak-sealing processes, but the gas cylinders or steam cannot maintain a stable leak pressure. The characteristics and ideas of these leak-sealing simulation training device designs provide reference and ideas for the design of multifunctional leak-sealing simulation training devices. To overcome the shortcomings of the above-mentioned leak-sealing simulation training devices, integrate leak scenarios from fixed sources such as chemical plants and mobile sources such as hazardous chemical tank trucks, break through the limitations of fixed leak points, single shapes, and uncontrollable gas and liquid leak media, and optimize the leak-sealing effect evaluation system, it is very important and necessary to design a multifunctional leak-sealing simulation training device.

The outlet end of the liquid supply device 2 is connected to the inlet end of the simulated leak device 1 via a pipe, and the outlet end of the gas supply device 3 is connected to the inlet end of the simulated leak device 1 via a pipe. The simulated leak device 1 has an internal pipeline for connecting to the leak point. The inlet end of the internal pipeline is connected to the inlet end of the simulated leak device 1, and the outlet branch pipe 4 of the internal pipeline is connected to the leak point.

[0027] Working principle: Liquid supply device 2 generates and supplies liquid at a certain pressure to simulated leak device 1, while gas supply device 3 generates and supplies gas at a certain pressure to simulated leak device 1. The liquid or gas is transported within internal pipelines until it reaches the leak point through outlet branch pipe 4, creating a simulated leak effect. Liquid and gas supplies are switched separately as needed.

[0028] In one embodiment, each discharge branch pipe 4 is equipped with a flow control valve 5 for controlling the flow rate of the discharge branch pipe 4. The flow control valve 5 can individually adjust the flow rate of a specific discharge branch pipe 4, thereby achieving different leakage effects at different leakage locations.

[0029] In one embodiment, the simulated leak device 1 includes a tank 101 and at least one installation pipe 102 connected to the tank 101. At least one cylindrical body 103 communicating with the interior of the tank 101 and a pipe interface for connecting the installation pipe 102 are provided on the outer side of the tank 101. The inlet end of the tank 101 is the inlet end of the simulated leak device 1. The installation pipe 102 includes a first straight pipe section, a bent section, and a second straight pipe section connected in sequence. The first end of the installation pipe 102 is connected to the pipe interface via a flange. A shut-off valve 104 is provided on the installation pipe 102. Both the inlet end and the processing end of the shut-off valve 104 are connected to the installation pipe 102 via flanges. The shut-off valve 104 is located on either the first or second straight pipe section. The second end of the installation pipe 102 is sealed. The first tank leak point is located on the bottom surface of tank 101, the second tank leak point is located on the side of tank 101, and the third tank leak point is located at the junction of tank 101 and cylinder 103. The first pipeline leak point is located on the flange between shut-off valve 104 and installation pipe 102, the second pipeline leak point is located on the first or second straight pipe section, the third pipeline leak point is located on shut-off valve 104, and the fourth pipeline leak point is located on the bend. The internal pipeline is located inside tank 101, and the discharge branch pipe 4 connects the leak points on tank 101 to the pipeline interface. Table 1 is a comparison table of common leak locations, leak outlet shapes, and leak causes. This utility model determines the leak point locations based on the table below.

[0030] Table 1

[0031] In one embodiment, there are four installation pipes 102, each pipe including at least one of a first pipe leak point, a second pipe leak point, a third pipe leak point, or a fourth pipe leak point. All leak points on the four installation pipes 102 simultaneously include the first pipe leak point, the second pipe leak point, the third pipe leak point, and the fourth pipe leak point. During leak-sealing simulation training, multiple sets of training can be conducted simultaneously using leak points at the same location or leak points at different locations.

[0032] In one embodiment, a quick-release connector is provided at the first end of the mounting tube 102. The quick-release connector allows for the replacement and expansion of new functional modules; new functional modules can be replaced using the same mounting tube 102 for repeated operational training. It also allows for changes to the leak location, leak outlet shape, and size to meet the needs of different leak scenarios.

[0033] In one embodiment, there are two cylinders 103, and at least one third tank leakage point is provided at the joint position of each cylinder 103 and the tank 101. During leakage plugging simulation training, multiple sets of training can be conducted simultaneously using leakage points at the same location or leakage points at different locations.

[0034] In one embodiment, the liquid supply device 2 includes a storage tank 201, a centrifugal pump 202, a pressure monitor 203, and a pressurization tank 204. The outlet of the storage tank 201 is connected to the inlet of the centrifugal pump 202 via a pipeline, and the outlet of the centrifugal pump 202 is connected to the inlet of the pressurization tank 204 via a pipeline. The outlet of the pressurization tank 204 is connected to the inlet of the simulated leak device 1. The pressure monitor 203 is installed on the pipeline between the centrifugal pump 202 and the pressurization tank 204. The liquid supply device 2 also includes a frequency converter control cabinet 205 for controlling the operating intensity of the centrifugal pump 202. To make the pressure of the leaked liquid (e.g., water) adjustable and controllable, the frequency converter control cabinet 205 is used to change the speed of the centrifugal pump 202, thereby achieving water supply and primary pressurization. The pressurization tank 204 is used for secondary pressurization, reducing the start-stop frequency of the centrifugal pump 202, so that the liquid pressure can be smoothly regulated. The pressure monitor 203 can monitor the pressure value of the first pressurization in real time, thereby determining the pressure value that the pressurizing tank 204 should apply. During operation, the storage tank 201 is switched to the discharge state, and the frequency converter control cabinet 205 is set to automatic operation of the centrifugal pump 202. The centrifugal pump 202 begins pumping water and providing system pressure, while the pressurizing tank 204 performs secondary pressurization. After the pressure reaches the preset value, the frequency converter control cabinet 205 controls the pressure to stabilize, and the pressurized medium flows out from the leakage point. When the pressure does not meet the set pressure, the centrifugal pump 202 and the pressurizing tank 204 continue to operate to maintain pressure stability. The storage tank 201 has a capacity of 1000L, and the pressure tank is a diaphragm type.

[0035] In one embodiment, the gas supply device 3 includes a steam boiler 301, which is equipped with a feed valve 302, a main gas valve 303, a drain valve 304, and a safety valve 305. The steam boiler 301 also includes a level controller 306 and a pressure controller 307. The main gas valve 303 is connected to the feed end of the simulated leak device 1 via a pipeline. The steam boiler 301 heats the internal liquid (e.g., water), causing it to evaporate and form a high-pressure gaseous leak substance. This gaseous leak substance is discharged from the main gas valve 303 and enters the internal piping network, ultimately forming a leak at the leak location. The safety valve 305 prevents overpressure explosions and accidents. The drain valve 304 is used to discharge waste when cleaning the steam boiler 301 and its interior. The drain valve 304 and the feed valve 302 are separate to prevent blockage and obstruction of the feed. The level controller 306 can automatically replenish the liquid in the steam boiler 301 to prevent dry burning, and the pressure controller 307 can promptly provide feedback on the pressure information inside the steam boiler 301; it will also promptly issue an alarm when the pressure is abnormal. Both the level controller 306 and the pressure controller 307 are controlled by a control terminal located in the control box 308.

[0036] In one embodiment, the discharge end of the pressurization tank 204, the main air valve 303, and the inlet end of the simulated leakage device 1 are respectively connected to a three-way switching valve 6 via pipelines. The discharge end of the pressurization tank 204 is connected to the first inlet of the three-way switching valve 6, the main air valve 303 is connected to the second inlet of the three-way switching valve 6, and the inlet end of the simulated leakage device 1 is connected to the outlet of the three-way switching valve 6. The on / off states of the first and second inlets of the three-way switching valve 6 are opposite: when the first inlet is connected to the outlet, the second inlet is disconnected from the outlet; when the second inlet is connected to the outlet, the first inlet is disconnected.

[0037] In one embodiment, an automatic detection and control system is also included. This system comprises a control system, a control terminal, and an automatic leak-stopping effect evaluation system. The control system controls the on / off state of the flow control valve 5 to control the opening and closing of the leaking part. In this invention, the flow control valve 5 is a PLC-guided pneumatic solenoid valve. This system has a short response time, is simple to operate, and has a wide range of applications. A pressure sensor is also installed at the discharge branch pipe 4. The flow control valve 5 and the pressure sensor are connected to the PLC to control the opening and closing of the leaking part and to store and process pressure data. The control terminal is implemented by connecting an IoT gateway and a remote control to the PLC control system. The IoT control system connects the PLC to the IoT gateway and, using wireless transmission methods such as wireless networks and WIFI, uploads pressure sensor data and solenoid valve control switch data to a remote computer or portable device. This enables remote PLC programming, remote data monitoring, pressure data acquisition and display, and data application.

[0038] The handheld remote control terminal can serve as a backup control terminal when the wireless transmission path of the IoT control terminal is affected. It controls the opening and closing of the solenoid valve by adding an industrial remote controller. The remote controller has strong anti-interference capabilities and rapid response, and is used for emergency opening and closing of leaking parts, preventing the IoT control terminal from being unable to control the opening and closing of leaking parts due to network fluctuations.

[0039] To better reflect the effectiveness of leak sealing, this device employs an automated evaluation system based on Internet of Things (IoT) technology to objectively assess the sealing results. The system uses a programmed PLC to have pressure sensors detect initial and final pressure values, pressure changes, effective initial pressure, and pressure comparison values, uploading these data to the PLC's memory. An IoT gateway then provides real-time feedback of the leak pressure to a portable display device, which displays these pressure values ​​on a screen via cloud configuration. Once the leak is sealed, the pressure continues to rise to its maximum value. At this point, the leak sealing is considered complete, and the test timing ends. A delay timer records the pressure maintained for a fixed period; if there is no significant pressure drop, the leak sealing is successful. A significant pressure drop indicates the leak has not been completely sealed. The evaluation system analyzes the detected data to derive various detection values ​​and automatically evaluates the sealing effect based on the recorded data. This eliminates the need for manual verification of sealing success, avoiding the influence of human factors during training, assessments, or competitions, and ensuring fair and impartial results.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model.
