Description

Technical Field

[0001] This invention relates to the field of fire drill equipment, and more particularly to a training device for handling hazardous chemical tanker leaks. Background Technology

[0002] In recent years, with the increasingly widespread application of tank trucks and the continuous development of highway infrastructure, tank trucks have become an important tool for the inter-regional transportation of natural gas. As mobile pressure vessels, LPG, LNG, and CNG tank trucks are more prone to leakage due to the pressurized nature of the tanks themselves and the potential risks during transportation. The uncertainty of accident locations, the complexity of the on-site environment, the diversity of leakage scenarios, and the flammability and explosiveness of the leaked media make the handling of such accidents highly dangerous, technically complex, and difficult. Fire and rescue teams are increasingly emphasizing training to improve their operational capabilities in handling LPG tank truck accidents. However, there are relatively few training devices for LPG tank truck leak accidents, and some training devices have limited functions and structures, resulting in unsatisfactory training effects. Therefore, the construction of a multi-functional, comprehensive tank truck training device that meets actual combat needs is urgently needed.

[0003] In fire drills for handling leaks from hazardous chemical tanker trucks, scrapped tanker trucks are typically used as training subjects. The tanker is filled with a non-toxic, harmless simulated fluid (gas or liquid). The instructor creates an artificial leak point at any location on the tanker, simulating a fluid leak. Trainees then follow strict leak handling procedures to seal the leak point, completing the fire drill. However, each drill requires creating an artificial leak point on the tanker, limiting its lifespan and making it unsuitable for repeated drills. Furthermore, after sealing the leak point, the instructor cannot quickly verify its effectiveness, impacting the overall efficiency of the drill and subsequent tanker repair. Summary of the Invention

[0004] To overcome the shortcomings of fire drills involving the repeated artificial creation of leak points in hazardous chemical tanker leak response training, which can shorten the service life of the tanker and make it unsuitable for repeated drills over a long period, as well as the low efficiency of leak point sealing qualification testing, which affects the efficiency of drills and subsequent tanker repair, this invention provides a hazardous chemical tanker leak response training device.

Experts and firefighters jointly review and determine the modules, and are responsible for software compilation, implementation, and solenoid valve hardware linkage. Attached Figure Description

[0044] Preparation of this hazardous chemical tanker leak response training device:

[0045] The fluid transport device 31 is filled with a colorless and odorless simulated fluid, and the two storage tanks 8 are filled with a colored detection fluid.

[0046] First, the instructor opens the side covers 21 at both ends of the tank 2 and installs two U-shaped plates 7 with leak holes of arbitrary shapes on the outer ends of the two leak pipes 61. Then, the instructor controls the electric push rod 41 to move the entire telescopic pipe backward, so that the two moving pipes 43 move their connected leak detection components backward along the adjacent connectors 341. The two leak pipes 61 are retracted into the tank 2. Then, the instructor rotates the two ring frames 4. At the same time, the ring frames 4 drive the transfer pipe 34 to rotate along the diversion pipe 32 and the side support 33 through the moving pipes 43 until the two leak pipes 61 are aligned with the two positioning slots 201 in different directions. Then, the instructor controls the electric push rod 41 to move the entire telescopic pipe forward to reset, so that the two moving pipes 43 move their connected leak detection components forward along the adjacent connectors 341. The two leak pipes 61 are released outward to the corresponding positioning slots 201, completing the directional adjustment of the two leak pipes 61 and their connected U-shaped plates 7, so that the position of the U-shaped plates 7 needs to be handled in each exercise.

[0047] Finally, the instructor closed the side covers 21 at both ends of the tank 2 back to their original positions, preparing to begin the drill for handling hazardous chemical tanker leaks.

[0048] The drills for handling hazardous chemical tanker leaks using this training device were conducted as follows:

[0049] The fluid conveying equipment 31 conveys colorless and odorless simulated fluid to the diversion pipe 32 through the conveying pipe 311. The simulated fluid enters the two transfer pipes 34 along the diversion pipe 32, and enters the adjacent moving pipe 43 through the connector 341. Then it is sprayed outward from the leakage hole of the square plate 7 through the adjacent leakage pipe 61, thus starting the drill of the hazardous chemical tanker leakage disposal training device.

[0050] After the instructor signals the start of the drill to the trainees, the trainees follow the strict leakage handling training procedure to seal the leakage holes of the U-shaped plate 7. The difficulty of sealing the leakage holes of the U-shaped plate 7 varies depending on its structure. After the trainees complete the sealing of the leakage holes of the U-shaped plate 7, the simulated fluid that has entered the leakage pipe 61 cannot be discharged from the leakage holes of the U-shaped plate 7 in time. This causes the simulated fluid in the moving pipe 43 and the leakage pipe 61 to gradually accumulate. The simulated fluid that remains in the moving pipe 43 enters the expansion bladder 51 through the nozzle 431. The simulated fluid inflates the expansion bladder 51 in all directions. When the inflated expansion bladder 51 comes into contact with the pressure sensors 52 on the left and right sides, the pressure sensors 52 send a signal to the fluid delivery device 31 through the circuit system, indicating that the device has been triggered.

[0051] After all four pressure sensors 52 have fed back a triggered signal to the fluid delivery device 31 through the circuit system, it indicates that the trainee has completed the sealing of the leakage holes of the two I-beams 7. Subsequently, the fluid delivery device 31 stops delivering simulated fluid to the diversion pipe 32. At this time, the trainee can clearly hear the sound of the fluid delivery device 31 stopping. The trainee can quickly determine that the sealing of the leakage holes of the two I-beams 7 is complete. After the trainee has judged that the sealing of the leakage holes of the I-beams 7 is complete, the trainee sends a response to the instructor that the sealing work is complete.

[0052] When the instructor checks whether the sealing of the leakage hole of the U-shaped plate 7 is up to standard, the instructor first presses down on the U-shaped plate 7 to push the leakage pipe 61 backward along the annular frame 4. The leakage pipe 61 drives the output pipe 62, the mixing pipe 64, and the L-shaped pipe 65 to move closer to the moving pipe 43. The leakage pipe 61 compresses the first spring 63, and the L-shaped pipe 65 pushes the plug 651 into the outlet end of the branch pipe 81, connecting the internal space of the branch pipe 81 and the L-shaped pipe 65. The colored detection fluid in the storage tank 8 then passes through the branch pipe 81. If the L-shaped tube 65 enters the inlet groove 641 of the mixing tube 64, and there is still an inconspicuous gap in the leakage hole of the U-shaped plate 7, a small amount of simulated fluid will continue to flow out of the leakage hole of the U-shaped plate 7. At this time, the simulated fluid flowing through the inlet groove 641 mixes with the colored detection fluid and flows from the outlet groove 642 through the through hole 643 into the leakage tube 61, and then flows out from the leakage hole of the U-shaped plate 7. When the instructor sees the colored detection fluid flowing out of the U-shaped plate 7, he can determine that the sealing work of the leakage hole of the U-shaped plate 7 is unqualified.

[0053] When the instructor presses down on the I-beam 7 and does not see any colored detection fluid flowing out, the instructor then presses down on the detection block 71, causing the second spring 72 to move backward. This allows the L-shaped groove 711 of the detection block 71 to connect to the internal space of the leakage pipe 61 through the pressure relief hole 611. If no colored detection fluid flows out from inside the leakage pipe 61 through the pressure relief hole 611 and the L-shaped groove 711, the instructor will not see any colored detection fluid flowing out from the detection block 71. This indicates that there is no simulated fluid inside the leakage pipe 61, meaning that the simulated fluid has already leaked out completely from the leakage hole of the I-beam 7. Therefore, it can be determined that the sealing of the leakage hole of the I-beam 7 is seriously unqualified.

[0054] When the instructor presses the I-beam 7, no colored detection fluid is seen flowing out of the I-beam 7. However, when the detection block 71 is pressed, a large amount of colored detection fluid flows out of the detection block 71. This indicates that the colored detection fluid and the simulated fluid are sealed inside the leakage pipe 61 after mixing. The colored detection fluid and the simulated fluid will not leak out from the leakage hole of the I-beam 7. Therefore, it can be determined that the sealing work of the leakage hole of the I-beam 7 is qualified.

[0055] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention are existing technologies known to those skilled in the art.
