Description

Technical Field

[0001] This invention relates to the field of emergency response equipment technology, and in particular to an emergency response equipment for dangerous goods container leaks. Background Technology

[0002] Container transport of dangerous goods is a high-risk operation at port terminals. During loading, transportation, and unloading, various uncertainties may lead to abnormal situations such as damage or leakage of dangerous goods packaging containers.

[0003] When transporting chlorine (Cl2) in existing dangerous goods containers, negative pressure filters are used to maintain negative pressure inside the container to prevent chlorine from leaking out during transport. Since chlorine leaks inside the container cannot be directly observed by the naked eye, people outside may open the container door when a chlorine leak occurs, resulting in the chlorine being directly inhaled and causing harm to their health.

The two gears drive the rotating hook to rotate, so that the notch of the rotating hook engages with the hanging rod. At this time, the cabinet door is locked from the inside. This device can lock the cabinet door from the inside in case of chlorine gas leakage, preventing external personnel from opening the container door because they cannot directly observe the chlorine gas leak with the naked eye, which would cause the chlorine gas to be directly inhaled by the external personnel and thus cause harm to their health.

[0015] 2. The negative pressure filter drives airflow, which in turn drives the fan blades to rotate. The fan blades, through a rotating shaft, drive the fixed ring to rotate. The fixed ring causes the striking rod to collide with the inside of the striking cylinder. This device allows the negative pressure filter to strike the striking cylinder and produce a sound when filtering leaking chlorine gas, thus alerting external personnel to the gas leak inside the hazardous materials container.

[0028] Reference Figures 1-8An emergency handling device for leaks in a hazardous materials container includes a hazardous materials container body 1. One end of the container body 1 has an opening, and two cabinet doors are symmetrically arranged on the inner wall of the opening. Hanging rods 6 are fixedly installed on the top of each cabinet door near the outer surface of the container body 1. Two first support blocks 7 are symmetrically fixedly installed on the inner wall of the container body 1 near the hanging rods 6. Gears 10 are rotatably installed on the upper surface of each of the two first support blocks 7. A rotating hook 8 is fixedly installed through the bottom end of each gear 10, penetrating the lower surface of the first support block 7. A notch is formed on the outer surface of the rotating hook 8 near the hanging rods 6, and the hanging rods 6 are matched with the notch. A second support block 13 is fixedly installed on the inner wall of the container body 1 near the hanging rods 6. A square opening is formed through the outer surface of the second support block 13, and a square sliding rod 9 is slidably installed on the inner wall of the square opening. A first rack 11 is fixedly installed at one end of the rod 9 near the two gears 10. A second rack 12 is also fixedly installed at one end of the square slide rod 9 near the two gears 10. The first rack 11 and the second rack 12 are arranged opposite to each other. The first rack 11 meshes with one of the gears 10, and the second rack 12 meshes with the other gear 10. A fixing cylinder 5 is fixedly installed on the inner wall of the dangerous goods container body 1 near the hanging rod 6. The end of the fixing cylinder 5 away from the hanging rod 6 is provided with a through hole. A piston plate 16 is fixedly installed at the other end of the square slide rod 9 through the end face of the other end of the fixing cylinder 5. The piston plate 16 is slidably installed on the inner wall of the fixing cylinder 5. An installation plate 501 is fixedly installed on the inner wall of the fixing cylinder 5 away from the piston plate 16. A spring 502 is fixedly installed on the outer surface of one side of the installation plate 501. The other end of the spring 502 is fixedly installed on the outer surface of the piston plate 16.

[0029] The movement of the piston plate 16 drives the square slide rod 9 to move. The square slide rod 9 drives the two gears 10 to rotate in opposite directions through the first rack 11 and the second rack 12. The two gears 10 drive the rotating hook 8 to rotate, so that the notch of the rotating hook 8 engages with the hanging rod 6. At this time, the cabinet door is locked from the inside. This device can lock the cabinet door from the inside in case of chlorine gas leakage, preventing external personnel from opening the container door because they cannot directly observe the chlorine gas leak with the naked eye, which would cause the chlorine gas to be directly inhaled by the external personnel and thus cause harm to their health.

[0030] In this embodiment, a gas valve 14 is fixedly installed at one end of the fixed cylinder 5 near the hanging rod 6. The gas valve 14 is connected to the inside of the fixed cylinder 5. A pressure sensor 15 is fixedly installed at one end of the fixed cylinder 5 near the gas valve 14. One end of the pressure sensor 15 is located inside the fixed cylinder 5.

[0031] Compressed air at a certain pressure is injected into the fixed cylinder 5 through the gas valve 14. When the piston plate 16 slides and comes into contact with the pressure sensor 15, the pressure sensor 15 receives an electrical signal, which causes the negative pressure filter 2 to increase its filtration efficiency and prevent chlorine leakage.

[0032] In this embodiment, a negative pressure filter 2 is fixedly installed on the top wall of the dangerous goods container body 1. An air outlet pipe 3 is provided on the upper surface of the negative pressure filter 2. The air outlet end of the air outlet pipe 3 passes through the upper surface of the dangerous goods container body 1. A sliding sleeve 17 is fixedly installed on the outer surface of the fixed cylinder 5 near the negative pressure filter 2. The sliding sleeve 17 is connected to the interior of the fixed cylinder 5. A square sliding column 18 is slidably installed on the inner wall of the sliding sleeve 17. One end of the square sliding column 18 abuts against the outer surface of the piston plate 16. An annular groove 1601 is provided on the outer circumference of the piston plate 16 near the mounting plate 501. One end of the square sliding column 18 abuts against the inner wall of the annular groove 1601.

[0033] When the annular groove 1601 on the piston plate 16 slides to the position of the square slide post 18, one end of the square slide post 18 slides into the interior of the annular groove 1601 under the force of the tension spring 23. This device restricts the position of the piston plate 16 and prevents the rotating hook 8 from being unlocked.

[0034] In this embodiment, a rotating shaft 21 is rotatably mounted on the other end of the square sliding column 18. An air inlet pipe 4 is provided on the outer surface of the negative pressure filter 2 near the rotating shaft 21. A fixing plate 19 is fixedly mounted on the inner wall of the air inlet pipe 4. A drive fan blade 20 is fixedly mounted on one end of the rotating shaft 21 through the outer surface of the fixing plate 19. A frustum 29 is fixedly mounted on the outer circumference of the rotating shaft 21. An angle is provided on the outer surface of the frustum 29. A chamfer 30 matching the angle is provided on the outer surface of the fixing plate 19 near the frustum 29. The rotating shaft 21 and the fixing plate 19 are slidably mounted. A fixing ring 27 is fixedly mounted on the outer circumference of the rotating shaft 21 near the frustum 29. An annular groove is provided on the outer circumference of the fixing ring 27. Multiple striking rods 28 are rotatably mounted at equal intervals on the inner wall of the annular groove. A striking cylinder 31 is fixedly mounted on the outer surface of the fixing plate 19 near the fixing ring 27. The end of the striking rod 28 abuts against the inner wall of the striking cylinder 31.

[0035] When the truncated cone 29 moves away from the chamfer 30, the position of the rotating shaft 21 is unrestricted. The airflow driven by the negative pressure filter 2 will drive the drive fan blade 20 to rotate. The drive fan blade 20 drives the fixed ring 27 to rotate through the rotating shaft 21. The fixed ring 27 drives the striking rod 28 to collide with the inside of the striking cylinder 31. This device allows the negative pressure filter 2 to strike the striking cylinder 31 to make a sound when filtering leaked chlorine gas, which is used to alert external personnel that there is a gas leak inside the dangerous goods container body 1.

[0036] In this embodiment, a stop block 25 is fixedly installed on the outer surface of the square sliding column 18 near the other end. A tension spring 23 is sleeved on the outer surface of the square sliding column 18. One end of the tension spring 23 is fixedly connected to the outer surface of the stop block 25, and the other end of the tension spring 23 is fixedly connected to the outer surface of the sliding sleeve 17. An installation sleeve 2201 is fixedly installed on the upper surface of the dangerous goods container body 1. A lever 22 is rotatably installed on the inner wall of the installation sleeve 2201. The bottom end of the lever 22 penetrates the inner wall of the dangerous goods container body 1 and has a guide groove 24. Two guide posts 26 are symmetrically fixedly installed on the outer circumference of the stop block 25. The two guide posts 26 are slidably installed on the inner wall of the guide groove 24.

[0037] By manually moving the lever 22, the square sliding column 18 is driven to reset through the guide column 26 and guide groove 24. At this time, the piston plate 16 is reset by the high pressure gas inside the fixed cylinder 5. This device can release the lock of the rotating hook 8, making it easier to open the cabinet door. It should be noted that in the initial state, the end of the square sliding column 18 is abutting against the outer circumference of the piston plate 16.

[0038] In this embodiment, the surface roughness of the contact surface between the frustum 29 and the chamfer 30 is greater than Ra3.2, so that when the two are in contact, the rotation of the shaft 21 can be prevented by the friction between them.

[0039] It should be noted that before use, compressed air at a certain pressure is injected into the fixed cylinder 5 through the gas valve 14. During use, the operator places the chlorine gas into the interior of the hazardous materials container body 1, then closes the container door, and opens the negative pressure filter 2 to maintain a negative pressure state inside the hazardous materials container body 1. The negative pressure filter 2 is equipped with a filter bag, which filters out chlorine gas leaks to prevent leakage into the air. When chlorine gas leaks inside the hazardous materials container body 1, the internal pressure suddenly increases. At this time, the pressure difference between the compressed gas inside the fixed cylinder 5 and the pressure inside the hazardous materials container body 1... As the pressure decreases, under the action of spring 502, piston plate 16 moves closer to hanging rod 6. The movement of piston plate 16 drives square sliding rod 9 to move. Square sliding rod 9 drives two gears 10 to rotate in opposite directions through first rack 11 and second rack 12. The two gears 10 drive rotating hook 8 to rotate, so that the notch of rotating hook 8 engages with hanging rod 6. At this time, the cabinet door is locked from the inside. This device can lock the cabinet door from the inside in case of chlorine gas leakage, preventing external personnel from opening the container door because they cannot directly observe the chlorine gas leak and thus inhaling the chlorine gas directly, causing harm to their health. Through the sliding of piston plate 16, when piston plate 16 moves closer to hanging rod 6, the pressure sensor... When the pressure sensor 15 is pressed against the ground, it receives an electrical signal, causing the negative pressure filter 2 to increase its filtration efficiency and prevent chlorine leakage. When the annular groove 1601 on the piston plate 16 slides to the position of the square slide column 18, one end of the square slide column 18 slides into the annular groove 1601 under the force of the tension spring 23. This device restricts the position of the piston plate 16, preventing the rotating hook 8 from being unlocked. At this time, the truncated cone 29 moves away from the chamfer 30, and the position of the rotating shaft 21 is released. The negative pressure filter 2 drives the airflow, which drives the drive fan blade 20 to rotate. The drive fan blade 20 drives the fixed ring 27 to rotate through the rotating shaft 21. The fixed ring 27 drives the striking rod 28 and the striking cylinder 31 to rotate. The internal collision of the components allows the negative pressure filter 2 to strike the striking cylinder 31 and make a sound when filtering leaked chlorine gas, thus alerting external personnel that there is a gas leak inside the dangerous goods container body 1. After external personnel have checked that the gas filtration inside the dangerous goods container body 1 is complete, they can manually move the lever 22 to drive the square sliding column 18 to reset through the guide column 26 and guide groove 24. At this time, the piston plate 16 resets through the high-pressure gas inside the fixed cylinder 5. This device can release the lock of the rotating hook 8, making it easier to open the cabinet door. It should be noted that in the initial state, the end of the square sliding column 18 is abutting against the outer circumferential surface of the piston plate 16.
