Description

Technical Field

[0001] This invention relates to a fire drill simulation device, and more particularly to an integrated module for hazardous chemical emergency training simulation. Background Technology

[0002] The transportation of hazardous chemicals involves flammable, explosive, and toxic substances such as liquefied natural gas, liquefied petroleum gas, and compressed natural gas. Due to the complex structure of vehicles and the dynamic changes in the environment, accidents during transportation are characterized by their suddenness, diversity, and cascading effects. For example, a vehicle overturning may lead to tank leaks, fires, or explosions, resulting in environmental pollution and casualties. Firefighters need a precise understanding of the vehicle's structure, such as the location of emergency shut-off valves and pipeline distribution, as well as the physical properties of the hazardous chemicals, such as pressure and temperature, to quickly develop a rescue plan. Traditional training often fails to cover these technical details.

[0003] Existing emergency training methods for hazardous chemical transportation suffer from problems such as limited simulation scenarios and low technological integration. Most training relies on simple operation drills using decommissioned vehicles, which cannot simulate the various types of valves on existing hazardous chemical transport vehicles, the various cracks and defects at accident sites, or the situation of hazardous chemical transport vehicles overturning. Furthermore, the training process is not repeatable, making it difficult to meet the needs of targeted, combat-oriented training. Summary of the Invention

[0004] Based on the above, the purpose of this invention is to provide a hazardous chemical emergency training simulation integrated module. This module has various types of valves and various crack defects, which can simulate real-life hazardous chemical emergency response scenarios, especially the situation of hazardous chemical transport vehicles overturning and tipping over, enabling trainees to effectively master the corresponding emergency response measures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The hazardous chemical emergency training simulation integrated module includes a chemical plant simulator and a hazardous chemical transportation simulator. The chemical plant simulator includes a chemical plant simulation tank, and the hazardous chemical transportation simulator includes a hazardous chemical transportation simulation tank. The chemical plant simulation tank and the hazardous chemical transportation simulation tank are fixed and horizontally set on a base.

[0007] One side of the chemical plant simulation tank is equipped with a fire inlet, a first pressure gauge, and multiple valves of different types. The fire inlet, the first pressure gauge, and each valve are connected by a pipe. The other side of the chemical plant simulation tank is equipped with multiple defects of different types. The interior of the chemical plant simulation tank is divided into multiple defect training sections. Each defect training section is connected to one valve of one type and one defect of one type, thereby forming multiple defect training units.

[0008] A tilting mechanism is provided between the hazardous chemical transport simulation tank and the base. One end of the tilting mechanism is fixed to the base, and the other end is rotatably connected to the hazardous chemical transport simulation tank. The hazardous chemical transport simulation tank is tilted by the tilting mechanism.

[0009] As a preferred option for the integrated module for hazardous chemical emergency training simulation, the different types of valves include: turbine butterfly valves, ball valves, gate valves, globe valves, and handle-operated wafer butterfly valves.

[0010] As a preferred option for the integrated module for hazardous chemical emergency training simulation, the different types of defects include: crack defects, circular defects, triangular defects, transverse defects, and longitudinal defects.

[0011] As a preferred embodiment of the hazardous chemical emergency training simulation integrated module, the interior of the chemical plant simulation tank is divided into multiple defect training sections. Each defect training section is connected to a valve of a certain type and a defect of a certain type, thereby forming five defect training units. The multiple defect training sections are multiple pipes installed inside the chemical plant simulation tank. The turbine butterfly valve and the crack defect are connected by pipes to form a first defect training unit. The ball valve and the circular defect are connected by pipes to form a second defect training unit. The gate valve and the triangular defect are connected by pipes to form a third defect training unit. The gate valve and the transverse defect are connected by pipes to form a fourth defect training unit. The handle-type clamp butterfly valve and the longitudinal defect are connected by pipes to form a fifth defect training unit.

[0012] Alternatively, the multiple defect training sections are set inside the simulated tank of the chemical plant and divided into five independent defect training areas. The turbine butterfly valve and the crack defect are connected through the first defect training area to form a first defect training unit. The ball valve and the circular defect are connected through the second defect training area to form a second defect training unit. The gate valve and the triangular defect are connected through the third defect training area to form a third defect training unit. The gate valve and the transverse defect are connected through the fourth defect training area to form a fourth defect training unit. The handle-operated clamp butterfly valve and the longitudinal defect are connected through the fifth defect training area to form a corresponding fifth defect training unit.

[0013] As a preferred embodiment of the hazardous chemical emergency training simulation integrated module, the flipping mechanism specifically includes: a telescopic rod with one end rotatably connected to the base and the other end rotatably connected to a first position point of the hazardous chemical transport simulation tank; and a flipping support column with one end fixed to the base and the other end rotatably connected to a second position point of the hazardous chemical transport simulation tank. The line connecting the first position point and the second position point is not parallel to the length direction line of the hazardous chemical transport simulation tank. When the telescopic rod extends or retracts, the spatial position of the first position point relative to the second position point changes, and the hazardous chemical transport simulation tank flips and tilts along the second position point. The telescopic rod is driven to extend or retract by a driving device.

[0014] As a preferred embodiment of the hazardous chemical emergency training simulation integrated module, the first position point is the midpoint of the length direction line on the surface of the hazardous chemical transport simulation tank. A first support bar is fixedly connected to the first position point along the length direction. The first support bar is connected to the other end of the telescopic rod through a first hinge. One end of the telescopic rod is connected to the base through a third hinge. A second support bar is fixedly connected to the second position point. The second support bar is connected to the other end of the flip support column through a second hinge. One end of the flip support column is fixedly connected to the bottom of the hazardous chemical transport simulation tank.

[0015] As a preferred embodiment of the hazardous chemical emergency training simulation integrated module, the tilting mechanism further includes a hydraulic cylinder and a support column. The hydraulic cylinder drives the telescopic rod, and the support column overlaps with the first support bar. It also includes a power switch, a hydraulic start / stop switch, an emergency stop switch, a manual / automatic switching knob, and a lifting knob.

[0016] As a preferred embodiment of the hazardous chemical emergency training simulation integrated module, the hazardous chemical transportation simulation tank also includes an operation box, which is divided into an LPG operation box and a LPG operation box.

[0017] As a preferred embodiment of the hazardous chemical emergency training simulation integrated module, both the liquefied petroleum gas control box and the liquefied natural gas control box are equipped with emergency shut-off valves between themselves and the hazardous chemical transportation simulation tank.

[0018] As a preferred embodiment of the hazardous chemical emergency training simulation integrated module, the liquefied petroleum gas (LPG) control box is equipped with: a first electrostatic grounding reel, a thermometer, a second pressure gauge, an emergency shut-off valve puller, an inlet / outlet, a first gas phase balance port, inlet / outlet emergency shut-off valve levers, and a gas phase balance port emergency shut-off valve lever; the liquefied natural gas (LNG) control box is equipped with: a first natural gas shut-off valve, a second natural gas shut-off valve, a third natural gas shut-off valve, a second gas phase balance port, a loading / unloading port, and a second electrostatic grounding reel.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. Through understanding and operating various valves, trainees can improve their valve control capabilities in emergency handling of hazardous chemicals, ensuring that the flow of hazardous chemicals can be cut off in a timely manner to prevent the accident from escalating;

[0041] This embodiment provides a hazardous chemical emergency training simulation integrated module, such as... Figures 1 to 3As shown, the system includes a chemical plant simulator 100 and a hazardous chemical transport simulator 200. By setting up two operating areas, trainees can conduct specialized training for different types of hazardous chemical transport vehicles, improving their ability to respond to accidents involving specific transport vehicles. The chemical plant simulator 100 includes a chemical plant simulation tank 110, and the hazardous chemical transport simulator 200 includes a hazardous chemical transport simulation tank 210. The chemical plant simulation tank 110 and the hazardous chemical transport simulation tank 210 are fixed and horizontally set on a base 300. The base 300 is in the form of two steps, with the hazardous chemical transport simulation tank 210 at the lower part of the base 300 and the chemical plant simulation tank 110 at the higher part. Multiple toolboxes 301 are set below the higher part of the base 300, and a step 302 is set at one end of the higher part of the base 300. The toolboxes 301 are used to store tools and instruments needed during training and maintenance. The step 302 facilitates maintenance personnel to climb the higher part of the base 300 for maintenance, thereby improving the integration and convenience of the system.

[0042] In this embodiment, a fire inlet 111, a first pressure gauge 112, and multiple valves of different types are provided on one side of the chemical plant simulation tank 110. The fire inlet 111, the first pressure gauge 112, and each valve are connected by a pipeline. The fire inlet 111 is used to connect a fire pump to provide the water source required for the simulation of the chemical plant simulation tank 110. The first pressure gauge 112 is used to display the water pressure in the pipeline. Multiple defects of different types are provided on the other side of the chemical plant simulation tank 110. The interior of the chemical plant simulation tank 110 is divided into multiple defect training sections. Each defect training section corresponds to a different type of valve and a different type of defect, thus forming multiple defect training units. The setting of multiple defect training units helps trainees become familiar with the operation of different types of valves and defects of chemical plants, master the corresponding emergency handling measures, and improve their ability to deal with complex situations.

[0043] Specifically, the different types of valves include: turbine butterfly valve 121, ball valve 122, gate valve 123, gate valve 124, and handle-operated wafer butterfly valve 125; the different types of defects include: crack defect 131, circular defect 132, triangular defect 133, transverse defect 134, and longitudinal defect 135. The five defect drill units correspond to five types of valves and five types of defects, encompassing most situations that may occur in actual hazardous chemical accidents. Through understanding and operating various valves and defects, trainees can improve their valve control and defect handling capabilities in hazardous chemical emergency response, ensuring the timely shut-off of hazardous chemical flow and leakage, and preventing further escalation of the accident.

[0044] Optionally, multiple defect simulation sections are constructed using multiple pipes installed inside the simulated chemical tank 110. A turbine butterfly valve 121 and a crack defect 131 are connected via pipes to form a first defect simulation unit; a ball valve 122 and a circular defect 132 are connected via pipes to form a second defect simulation unit; a gate valve 123 and a triangular defect 133 are connected via pipes to form a third defect simulation unit; a gate valve 124 and a transverse defect 134 are connected via pipes to form a fourth defect simulation unit; and a handle-operated clamp butterfly valve 125 and a longitudinal defect 135 are connected via pipes to form a fifth defect simulation unit. The valves and defects are directly connected via pipes to simulate the leakage of hazardous chemicals from tank defects. Because the pipe volume is relatively small, this scheme allows for a smaller liquid capacity, reducing simulation consumption, increasing simulation speed, and providing better sealing performance.

[0045] Alternatively, multiple defect simulation sections are set inside the simulated chemical plant tank 110 and divided into five independent defect simulation zones by partition plates 120. The turbine butterfly valve 121 and the crack defect 131 are connected through the first defect simulation zone to form the first defect simulation unit; the ball valve 122 and the circular defect 132 are connected through the second defect simulation zone to form the second defect simulation unit; the gate valve 123 and the triangular defect 133 are connected through the third defect simulation zone to form the third defect unit; the gate valve 124 and the transverse defect 134 are connected through the fourth defect simulation zone to form the fourth defect unit; and the handle-operated wafer butterfly valve 125 and the longitudinal defect 135 are connected through the fifth defect simulation zone to form the fifth defect unit. The valves and defects are connected through the defect simulation zones. The setup of these zones better reflects actual transportation and storage conditions, enabling better simulation of the state when a leak occurs, resulting in a more effective simulation.

[0046] Furthermore, each defect simulation area is equipped with a vent 113 at the top and a drain port 114 at the bottom. The vent 113 is used to release gas and protect the chemical plant simulation tank 110 from overpressure damage, while the drain port 114 is used to drain liquid and ensure that the interior of the chemical plant simulation tank 110 is completely emptied.

[0047] In practical applications, the specific operating steps of the chemical plant simulator 100 are as follows:

[0048] 1. Preparation stage

[0049] S1. Check whether all components of the chemical plant simulator 100 are intact, including the fire water inlet 111, various valves and partitions 120 of each defect drill area, etc.

[0050] S2. Confirm that the fire hydrant connection is normal and ensure sufficient water supply during the drill;

[0051] S3. Prepare necessary personal protective equipment, such as safety helmets, protective gloves, and goggles, to ensure the safety of operators. Take out the necessary tools and equipment from toolbox 301.

[0052] 2. Operational Phase

[0053] S1. Be familiar with the location and markings of various valves, such as turbine butterfly valve 121, ball valve 122, gate valve 123, gate valve 124, and handle-operated wafer butterfly valve 125, etc.

[0054] S2. Operate each valve one by one to understand its opening and closing methods and force. For example, for manual valves, control the opening and closing of the valve by rotating the valve handle.

[0055] S3. During operation, observe whether the valve operates smoothly and whether there is any leakage. If any problems are found, record and handle them in a timely manner.

[0056] S4. Practice operating valves quickly and accurately in emergency situations to control the flow of hazardous chemicals, using different simulated scenarios.

[0057] 3. Defect Drills

[0058] S1. Select the defective area to be practiced, and isolate other defective areas by operating the valves on the pipeline;

[0059] S2. Open the fire water inlet 111, adjust the water flow, and simulate a hazardous chemical leak or other emergency.

[0060] S3. Observe the condition of the defective area to determine the severity and scope of the accident;

[0061] S4. Depending on the type of defect, various sealing tools and methods are used to seal the leaks. For example, external sealing bags and cotton quilts are used for binding and sealing, strong magnetic sealing tools are used for covering and sealing, and on-site sealing clamps are used for sealing.

[0062] S5. During the drills, pay attention to communication and collaboration with team members to ensure the efficient execution of emergency response work.

[0063] 4. Conclusion

[0064] S1. Close the fire water inlet 111 and stop the water supply;

[0065] S2. Check that all valves are in the correct closed position to ensure the safety of the fixed device;

[0066] S3. Clean up the drill site and put the used tools and equipment back into toolbox 301;

[0067] S4. Summarize and evaluate the exercise process, analyze the problems and shortcomings in the operation, propose improvement measures, and prepare for the next exercise and actual combat.

[0068] In this embodiment, a flipping mechanism 220 and a flipping equipment operating table 230 are provided between the hazardous chemical transport simulation tank 210 and the base 300. One end of the flipping mechanism 220 is fixed to the base 300, and the other end is rotatably connected to the hazardous chemical transport simulation tank 210. The flipping equipment operating table 230 controls the flipping mechanism 220 to flip the hazardous chemical transport simulation tank 210. Through the flipping design of the tank, the simulation training is closer to the actual situation, and the emergency response capabilities of trainees in complex environments are improved. One end of the hazardous chemical transport simulation tank 210 is equipped with a ladder 211, a weld defect 212, and a weld defect ball valve switch 213. The top of the hazardous chemical transport simulation tank 210 is equipped with a safety valve 214 and a maintenance manhole 215. Maintenance personnel can climb to the top of the hazardous chemical transport simulation tank 210 via the ladder 211 and perform maintenance and repairs on the inside of the tank through the maintenance manhole 215. The weld defect 212 is connected to the weld defect ball valve switch 213 via a pipeline. When the weld defect ball valve switch 213 is opened, liquid will seep out from the weld defect 212, which is used to simulate the situation of tank damage and hazardous chemical leakage after an accident in the hazardous chemical transport device. Trainees can handle the weld defect 212 by turning the hazardous chemical transport simulation tank 210 over, so as to better simulate the on-site situation and improve the training effect. The safety valve 214 is in an automatic working state. When the system pressure exceeds the set value, the safety valve 214 will automatically open to release pressure and ensure safety.

[0069] Specifically, the hazardous chemical transport simulation tank 210 also includes an operation box, which is divided into an LPG operation box 240 and an LPG operation box 250, respectively simulating the transport of LPG and LPG. Both the LPG operation box 240 and the LPG operation box 250 are connected to the hazardous chemical transport simulation tank 210 through pipelines. An emergency shut-off valve 216 is installed on the pipeline. In case of emergency, such as leakage or other dangerous situations, the flow of fluid can be cut off in time by quickly operating the emergency shut-off valve.

[0070] In this embodiment, as Figure 4As shown, the liquefied petroleum gas control box 240 is equipped with: a first electrostatic grounding reel 241, a thermometer 242, a second pressure gauge 243, an emergency shut-off valve puller 244, an inlet / outlet port 245, a first gas phase balance port 246, an inlet / outlet emergency shut-off valve lever 247, and a gas phase balance port emergency shut-off valve lever 248. The first static grounding reel 241 is installed on the inner wall of the liquefied petroleum gas operating box 240 to conduct static electricity accumulated on equipment or vehicles to the ground, avoiding the risk of sparks and explosions caused by static electricity accumulation. The thermometer 242 and pressure gauge 243 are used to display the temperature and pressure values ​​inside the hazardous chemical transport simulation tank 210. When the temperature and pressure values ​​exceed the set values, the emergency shut-off valve 216 is shut off by the emergency shut-off valve puller 244 to prevent accidents. The inlet and outlet ports 245 are used to fill the hazardous chemical transport simulation tank 210 with liquid. The first gas phase balance port 246 is used to balance the pressure inside the tank when filling the hazardous chemical transport simulation tank 210 with liquid, preventing liquid backflow caused by pressure difference. In case of an accident or when the device is no longer in use, the inlet and outlet ports 245 and the first gas phase balance port 246 are shut off by the inlet and outlet emergency shut-off valve pull rods 247 and 248, respectively, to ensure safety. By installing the aforementioned components inside the liquefied petroleum gas control box 240, the scenario of an accident involving a liquefied petroleum gas transport vehicle is simulated, making the training more realistic and improving the trainees' emergency response capabilities in complex environments.

[0071] In this embodiment, as Figure 5As shown, the liquefied natural gas (LNG) control box 250 is equipped with: a first natural gas shut-off valve 251, a second natural gas shut-off valve 252, a third natural gas shut-off valve 253, a second gas phase balance port 254, a loading / unloading port 255, and a second static grounding reel 256. The first natural gas shut-off valve 251 consists of two DN25 shut-off valves connected to the second gas phase balance port 254 via a pipeline; the second natural gas shut-off valve 252 is a DN40 shut-off valve connected to the loading / unloading port 255 via a pipeline; the second gas phase balance port 254 and the loading / unloading port 255 are connected via a pipeline; the third natural gas shut-off valve 253 is a φ10 shut-off valve installed on the pipeline connecting the second gas phase balance port 254 and the loading / unloading port 255; the second static grounding reel 256 is installed on the inner wall of the LNG control box 240 to conduct static electricity accumulated on equipment or vehicles to the ground, preventing sparks and explosion hazards caused by static electricity accumulation. The loading / unloading port 255 is used to fill the hazardous chemical transport simulation tank 210 with liquid. The second gas phase balance port 254 is used to balance the internal pressure of the tank when filling it with liquid, preventing liquid backflow due to pressure difference. The first natural gas shut-off valve 251, the second natural gas shut-off valve 252, and the third natural gas shut-off valve 253 are used to shut off the second gas phase balance port 254, the loading / unloading port 255, and the pipelines connecting them in case of an emergency. By installing the aforementioned components inside the liquefied natural gas operation box 250, the scenario of an accident involving a liquefied natural gas transport vehicle is simulated, making the training more realistic and improving the emergency response capabilities of trainees in complex environments.

[0072] Furthermore, such as Figure 6 and Figure 7As shown, the tilting mechanism 220 specifically includes: a telescopic rod 222 with one end rotatably connected to the base 300 and the other end rotatably connected to the first position point of the hazardous chemical transport simulation tank 210; and a tilting support column 224 with one end fixed to the base 300 and the other end rotatably connected to the second position point of the hazardous chemical transport simulation tank. The line connecting the first and second position points is not parallel to the length direction line of the hazardous chemical transport simulation tank 210, but is perpendicular to the cross-section along the length direction and located on the surface of the hazardous chemical transport simulation tank 210. When the telescopic rod 222 extends or retracts, the spatial position of the first position point relative to the second position point changes, and the hazardous chemical transport simulation tank 210 tilts and tilts along the second position point. The telescopic rod 222 is driven by a driving device. The system can extend or shorten. The first position point is the midpoint of the length direction line on the surface of the hazardous chemical transport simulation tank 210. A first support bar 217 is fixedly connected to the first position point along the length direction. The first support bar 217 is connected to the other end of the telescopic rod 222 through the first hinge 225. One end of the telescopic rod 222 is connected to the base 300 through the third hinge 227. A second support bar 218 is fixedly connected to the second position point. The second support bar 218 is connected to the other end of the tilting support column 224 through the second hinge 226. One end of the tilting support column 224 is fixedly connected to the bottom of the hazardous chemical transport simulation tank 210, thereby realizing the tilting function of the hazardous chemical transport simulator 200, which is used for simulating the overturning accident of a hazardous chemical transport vehicle.

[0073] Specifically, the bottom of the hazardous chemical transport simulation tank 210 is symmetrically provided with a first support bar 217 and a second support bar 218 along the length of the tank. The tilting mechanism 220 includes a hydraulic cylinder 221, a telescopic rod 222, two support columns 223, two tilting support columns 224, a first hinge 225, two second hinges 226, and a third hinge 227. The driving device hydraulic cylinder 221 drives and connects to the telescopic rod 222. One end of the telescopic rod 222 is movably connected to the base 300 through the hinge joint of the third hinge 227, and the other end is movably connected to the first support bar 217 of the hazardous chemical transport simulation tank 210 through the hinge joint of the first hinge 225. The two support columns 223 overlap with the first support bar 217, and the two tilting support columns 224 are movably connected to the second support bar 218 through the hinge joints of the two second hinges 226. In the non-working state, the hazardous chemical transport simulation tank 210 is horizontally placed on two support columns 223 and two tilting support columns 224 via the first support bar 217 and the second support bar 218 at the bottom. In the tilting state, the hydraulic cylinder 221 drives the telescopic rod 222 to extend. Under the combined action of the first hinge 225, the second hinge 226 and the third hinge 227, the first support bar 217 of the hazardous chemical transport simulation tank 210, which is attached to the two support columns 224, is lifted. The hazardous chemical transport simulation tank 210 tilts along the second support bar 218 as the axis, with a maximum tilting angle of 70 degrees. This simulates the scenario of an actual hazardous chemical transport vehicle overturning in an accident, and improves the emergency response capabilities of trainees in difficult environments.

[0074] More specifically, such as Figure 8 As shown, the control panel 230 of the tilting device is equipped with a power switch 231, a hydraulic start / stop switch 232, an emergency stop switch 233, a manual / automatic switching knob 234, and a lifting knob 235, which are used to control the tilting mechanism 220. The power switch 231 is used to start the drive motor, and the hydraulic start / stop switch 232 is used to control the drive motor to drive the hydraulic pump to deliver hydraulic oil to the hydraulic cylinder 221, thereby driving the telescopic rod 222 to complete the extension and retraction. The emergency stop switch 233 is used to quickly stop the tilting mechanism 220 in case of an emergency to ensure safety. The manual / automatic switching knob 234 is used to switch the control state of the tilting mechanism 220. In manual mode, the tilting height is controlled by the lifting knob 235. In automatic mode, the tilting mechanism 220 will control the hazardous chemical transport simulation tank 210 to reach the maximum tilting angle. At this time, switching to manual mode will stop the tilting mechanism 220 and keep the hazardous chemical transport simulation tank 210 in the current state, thereby realizing flexible control of the tilting mechanism 220 to achieve the tilting height required for simulation training.
