Description

Technical Field

[0001] The invention relates to a fire drill simulation device, in particular to a hazardous chemical emergency training simulation integrated module. Background Art

[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 environment during transportation, accidents are often sudden, diverse, and cascading. For example, a vehicle overturning could cause a tank to leak, burn, or explode, leading to environmental pollution and casualties. Firefighters must have a precise understanding of the vehicle structure, such as the location of emergency shut-off valves and pipeline layout, as well as the physical properties of hazardous chemicals, such as pressure and temperature, to quickly develop rescue plans. Traditional training struggles to cover these technical details.

[0003] Existing emergency training methods for hazardous chemical transportation have problems such as single simulation scenarios and low technical integration. Most training relies on scrapped vehicles for simple operation drills. It is impossible to simulate the various types of valves on existing hazardous chemical transportation vehicles and the various cracks and defects at accident scenes. It is also impossible to simulate the overturning of hazardous chemical transportation vehicles. Moreover, the training process is not repeatable, making it difficult to meet the needs of practical and targeted training. Summary of the Invention

[0041] This embodiment provides a hazardous chemical emergency training simulation integrated module, such as Figures 1 to 3As shown, it includes a chemical plant simulator 100 and a hazardous chemical transport simulator 200. By setting up two operating areas, trainees can conduct special training for different types of hazardous chemical transport vehicles and improve their ability to deal with 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 arranged on a base 300. The base 300 is in the shape of two steps. The hazardous chemical transport simulation tank 210 is at the lower part of the base 300, and the chemical plant simulation tank 110 is at the upper part of the base 300. A plurality of tool boxes 301 are arranged below the upper part of the base 300, and a step 302 is arranged at one end of the upper part of the base 300. The plurality of tool boxes 301 are used to store tools and equipment needed during training and maintenance. The step 302 facilitates maintenance personnel to climb to the upper part of the base 300 for maintenance, thereby improving the integration and convenience of the device.

[0042] In this embodiment, a fire water inlet 111, a first pressure gauge 112 and a plurality of different types of valves are provided on one side of the chemical plant simulation tank 110. The fire water inlet 111, the first pressure gauge 112 and each valve are connected by a pipe. The fire water inlet 111 is used to connect a fire water pump to provide the chemical plant simulation tank 110 with the water source required for simulation. The first pressure gauge 112 is used to display the water pressure in the pipe. A plurality of different types of defects 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 a plurality of defect drill sections, each defect drill section corresponding to a different type of valve and a different type of defect, thereby forming a plurality of defect drill units. The provision of a plurality of defect drill units is conducive to helping trainees become familiar with different types of valve operations and chemical plant defects, master corresponding emergency response measures, and improve the ability to deal with complex situations.

[0043] Specifically, different valve types include turbine butterfly valves 121, ball valves 122, stop valves 123, gate valves 124, and handle-wafer butterfly valves 125; different defect types include crack defects 131, circular defects 132, triangular defects 133, transverse defects 134, and longitudinal defects 135. The five defect drill units correspond to five valve types and five defects, encompassing most of the scenarios that may arise in actual hazardous chemical accidents. By understanding and operating a variety of valves and defects, trainees can improve their valve control and defect handling capabilities in hazardous chemical emergency response, ensuring timely interruption of hazardous chemical flow and leakage to prevent further escalation of accidents.

[0044] Optionally, the multiple defect drill sections are multiple pipes arranged inside the simulated tank 110 of the chemical plant. The turbine butterfly valve 121 and the crack defect 131 are connected by pipes to form a first defect drill unit, the ball valve 122 and the circular defect 132 are connected by pipes to form a second defect drill unit, the stop valve 123 and the triangular defect 133 are connected by pipes to form a third defect drill unit, the gate valve 124 and the transverse defect 134 are connected by pipes to form a fourth defect drill unit, and the handle clamp butterfly valve 125 and the longitudinal defect 135 are connected by pipes to form a fifth defect drill unit. The valves and defects are directly connected by pipes to simulate the leakage of hazardous chemicals from tank defects. Because the pipe volume is small, the amount of liquid that can be loaded is correspondingly small, which can reduce simulation consumption, increase simulation speed, and have better sealing performance.

[0045] Alternatively, multiple defect drill sections are provided inside the simulated tank 110 of the chemical plant and are divided into five independent defect drill areas by a partition plate 120. The turbine butterfly valve 121 and the crack defect 131 are connected through the first defect drill area to form a corresponding first defect drill unit. The ball valve 122 and the circular defect 132 are connected through the second defect drill area to form a corresponding second defect drill unit. The stop valve 123 and the triangular defect 133 are connected through the third defect drill area to form a corresponding third defect drill unit. The gate valve 124 and the transverse defect 134 are connected through the fourth defect drill area to form a corresponding fourth defect drill unit. The handle clamp butterfly valve 125 and the longitudinal defect 135 are connected through the fifth defect drill area to form a corresponding fifth defect drill unit. The valves and defects are connected through the defect drill area. The setting of the defect drill area is more in line with actual transportation and storage conditions, and can better simulate the state when a leak occurs, resulting in a better simulation effect.

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

[0047] In actual application, the specific operation steps of the chemical plant simulator 100 are as follows:

[0048] 1. Preparation

[0050] S2. Confirm that the fire water source is properly connected and ensure that there is sufficient water supply during the drill;

[0051] S3. Prepare necessary personal protective equipment, such as a safety helmet, protective gloves, goggles, etc. to ensure the safety of the operator, and take out the necessary tools and equipment from the tool box 301.

[0052] 2. Operational phase

[0055] S3. During operation, observe whether the valve moves smoothly and whether there is any leakage. If any problem is found, record and handle it in time;

[0056] S4. Combine different simulation scenarios to practice operating valves quickly and accurately in emergency situations to control the flow of hazardous chemicals.

[0057] 3. Defect drills

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

[0061] S4. Use various leak-sealing tools and methods to seal leaks according to different defect types. For example, use external sealing leak-sealing bags and quilts for bundling, use strong magnetic leak-sealing tools for covering and sealing, and use on-site leak-sealing fixtures for sealing.

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

[0063] 4. Ending stage

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

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

[0068] In this embodiment, a flipping mechanism 220 and a flipping device operating console 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 device operating console 230 controls the flipping mechanism 220 to flip the hazardous chemical transport simulation tank 210. The flippable design of the tank makes the simulation training closer to the actual situation, thereby improving the emergency response capabilities of the trainees in complex environments. A ladder 211, a weld defect 212 and a weld defect ball valve switch 213 are provided at one end of the hazardous chemical transportation simulation tank 210. A safety valve 214 and an inspection manhole 215 are provided on the top of the hazardous chemical transportation simulation tank 210. Maintenance personnel climb up to the top of the hazardous chemical transportation simulation tank 210 from the ladder 211 and perform maintenance and inspection on the inside of the tank through the inspection manhole 215; the weld defect 212 is connected to the weld defect ball valve switch 213 through a pipeline. When the weld defect ball valve switch 213 is opened, liquid will seep out of the weld defect 212, which is used to simulate the situation where the tank is damaged and hazardous chemicals leak after an accident occurs in the hazardous chemical transportation device. The training personnel can better simulate the on-site situation and improve the training effect by handling the weld defect 212 when the hazardous chemical transportation simulation tank 210 is turned over; the safety valve 214 is in automatic working state. When the system pressure exceeds the set value, the safety valve 214 will automatically open to release the pressure and ensure safety.

[0069] Specifically, the hazardous chemical transport simulation tank 210 also includes an operation box, which is divided into a liquefied petroleum gas operation box 240 and a liquefied natural gas operation box 250, which simulate the conditions of transporting liquefied petroleum gas and liquefied natural gas, respectively; the liquefied petroleum gas operation box 240 and the liquefied natural gas operation box 250 are both connected to the hazardous chemical transport simulation tank 210 through a pipeline, and an emergency shut-off valve 216 is provided on the pipeline. In an emergency, such as leakage or other dangerous situations, the emergency shut-off valve can be quickly operated to cut off the flow of the fluid in time.

[0070] In this embodiment, if Figure 4As shown, the liquefied petroleum gas operating box 240 is provided with: a first electrostatic grounding reel 241, a thermometer 242, a second pressure gauge 243, an emergency shut-off valve hand puller 244, an inlet and outlet liquid port 245, a first gas phase balance port 246, an inlet and outlet emergency shut-off valve pull rod 247 and a gas phase balance port emergency shut-off valve pull rod 248. The first electrostatic grounding reel 241 is installed on the inner wall of the liquefied petroleum gas operating box 240, and is used to conduct static electricity accumulated on equipment or vehicles into the ground to avoid sparks and explosion hazards caused by static electricity accumulation; the thermometer 242 and the 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 closed by the emergency shut-off valve hand puller 244 to prevent accidents; the liquid inlet and outlet 245 is used to load liquid into the hazardous chemical transport simulation tank 210, and the first gas phase balance port 246 is used to balance the pressure inside the tank when loading liquid into the hazardous chemical transport simulation tank 210 to prevent liquid backflow caused by pressure difference. When an accident occurs or the device is no longer used, the liquid inlet and outlet 245 and the first gas phase balance port 246 are closed by the inlet and outlet emergency shut-off valve pull rods 247 and the gas phase balance port emergency shut-off valve pull rod 248 to ensure safety. By arranging the aforementioned components inside the liquefied petroleum gas operating box 240, a scenario in which an accident occurs in a liquefied petroleum gas transport vehicle is simulated, making the training closer to the actual situation and improving the trainees' emergency response capabilities in complex environments.

[0071] In this embodiment, if Figure 5As shown, liquefied natural gas operation 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 balancing port 254, a loading and unloading port 255, and a second static grounding reel 256. The first natural gas shut-off valve 251 is a pair of DN25 shut-off valves connected to the second gas-phase balancing port 254 via a pipe. The second natural gas shut-off valve 252 is a DN40 shut-off valve connected to the loading and unloading port 255 via a pipe. The second gas-phase balancing port 254 and the loading and unloading port 255 are connected by a pipe. The third natural gas shut-off valve 253 is a φ10 shut-off valve installed on the pipe connecting the second gas-phase balancing port 254 and the loading and unloading port 255. The second static grounding reel 256 is installed on the inner wall of the liquefied petroleum gas operation box 240 and is used to conduct static electricity accumulated in equipment or vehicles to the ground, preventing sparks and explosions caused by static electricity accumulation. Loading and unloading port 255 is used to load liquid into the simulated hazardous chemical transport tank 210. Second gas-phase balancing port 254 balances the internal pressure of the tank during loading, preventing liquid backflow caused by pressure differentials. First natural gas shut-off valve 251, second natural gas shut-off valve 252, and third natural gas shut-off valve 253, respectively, are used to shut off second gas-phase balancing port 254, loading and unloading port 255, and the connecting pipeline in the event of an emergency. By installing these components within LNG operation box 250, a scenario similar to an LNG transport vehicle accident is simulated, making training more realistic and enhancing trainees' emergency response capabilities in complex environments.

[0072] Furthermore, if Figure 6 and Figure 7As shown, the flipping 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 also includes a flip 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 connecting line between the first position point and the second position point is not parallel to the length direction line of the hazardous chemical transport simulation tank 210, and the length direction line is perpendicular to the cross section along the length direction and is located on the surface of the hazardous chemical transport simulation tank 210; when the telescopic rod 222 is extended or shortened, the spatial position of the first position point relative to the second position point changes, and the hazardous chemical transport simulation tank 210 flips and tilts along the second position point; the telescopic rod 222 is driven by the driving device It is moved to extend or shorten, the first position point is the midpoint of the length direction line of the surface of the hazardous chemical transportation simulation tank 210, and a first support bar 217 is fixedly connected through the first position point along the length direction, and the first support bar 217 is connected to the other end of the telescopic rod 222 through the first hinge 225, and one end of the telescopic rod 222 is connected to the base 300 through the third hinge 227; the second position point is fixedly connected with a second support bar 218, and the second support bar 218 is connected to the other end of the flip support column 224 through the second hinge 226, and one end of the flip support column 224 is fixedly connected to the bottom of the hazardous chemical transportation simulation tank 210, thereby realizing the flipping and tilting function of the hazardous chemical transportation simulator 200, which is used for simulation exercises when a hazardous chemical transportation vehicle flips and overturns.

[0073] Specifically, a first support bar 217 and a second support bar 218 are symmetrically arranged at the bottom of the hazardous chemical transportation simulation tank 210 along the length direction of the tank. The flipping mechanism 220 includes a hydraulic cylinder 221, a telescopic rod 222, two support columns 223, two flipping support columns 224, a first hinge 225, two second hinges 226 and a third hinge 227. The driving device hydraulic cylinder 221 drives 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 transportation simulation tank 210 through the hinge joint of the first hinge 225. The two support columns 223 are overlapped with the first support bar 217, and the two flipping support columns 224 are movably connected to the second support bar 218 through the hinge joints of the two second hinges 226. When in the non-working state, the hazardous chemical transport simulation tank 210 is horizontally placed on two support columns 223 and two flip support columns 224 through the first support bar 217 and the second support bar 218 at the bottom; when in the flipping state, the hydraulic cylinder 221 drives the telescopic rod 222 to extend, and under the joint 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 overlapped on the two support columns 224 is lifted, and the hazardous chemical transport simulation tank 210 is flipped along the second support bar 218 as the axis, with a maximum flipping angle of 70 degrees, thereby simulating the scenario of an actual hazardous chemical transport vehicle overturning in an accident, and improving the emergency response capabilities of trainees in difficult environments.

[0074] More specifically, if Figure 8 As shown, the tilting device operating console 230 is equipped with a power switch 231, a hydraulic start / stop switch 232, an emergency stop switch 233, a manual / automatic switch knob 234, and a lift knob 235 for controlling 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 extension and retraction. The emergency stop switch 233 is used to quickly stop the tilting mechanism 220 in an emergency to ensure safety. The manual / automatic switch knob 234 is used to switch the control state of the tilting mechanism 220. In manual mode, the lift knob 235 controls the tilting height. In automatic mode, the tilting mechanism 220 controls the hazardous chemical transport simulation tank 210 to reach its maximum tilting angle. At this time, the manual mode is switched on, the tilting mechanism 220 stops working, and the hazardous chemical transport simulation tank 210 remains in its current state, thus achieving flexible control of the tilting mechanism 220 and achieving the desired tilting height for simulation training.
