Description

Technical Field

[0001] This utility model belongs to the field of hazardous chemical transportation technology, specifically relating to an emergency protection device for the combined water and land transportation of hazardous chemicals. Background Technology

[0002] In the modern logistics system, waterway transportation has significant advantages such as large transport capacity and low cost, and undertakes a large number of hazardous chemical transport tasks. However, the flammable, explosive, toxic and harmful characteristics of hazardous chemicals make it highly likely that once a leakage accident occurs during water-land combined transport, it will cause devastating damage to personnel safety, ecological environment and surrounding facilities.

[0003] Currently, while emergency protective devices for the combined land and water transport of hazardous chemicals have played a protective role to some extent, there are still many problems that need to be solved. Existing protective devices mainly focus on the physical protection of hazardous chemical containers, such as preventing collisions that could cause container breakage during handling and loading / unloading, or securing containers during transport to reduce the risks caused by shaking. At the same time, some protective devices also take into account the collection and treatment of waste liquid after leakage of liquid hazardous chemicals, such as setting up special collection tanks and drainage pipes to prevent the leaked liquid from spreading further and causing pollution over a larger area.

[0004] However, when hazardous chemicals leak, especially volatile hazardous chemicals, they will rapidly release toxic and harmful gases, posing a serious threat to the surrounding environment and human health. Existing emergency protection devices generally lack the function of effectively treating leaked gases. These leaked gases may spread to a large area in a short period of time. If they are in densely populated areas or poorly ventilated places, the degree of harm will be amplified dramatically.

[0005] Therefore, it is evident that developing an emergency protection device for combined land and water transport that can effectively treat leaked gases and reduce their toxicity in the event of hazardous chemical leaks is of great practical significance and urgency. Utility Model Content

[0006] The purpose of this invention is to provide an emergency protection device for the combined land and water transport of hazardous chemicals, which can quickly adsorb and neutralize toxic gases when hazardous chemicals leak, and can rapidly absorb and preserve the released toxic gases to prevent their further spread.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] An emergency protection device for the combined land and water transport of hazardous chemicals includes a storage compartment. Two partitions are provided inside the storage compartment and near both ends of the storage compartment. The two partitions divide the interior of the storage compartment into an installation cavity, a liquid storage cavity, and a gas storage cavity. The installation cavity is located between the two partitions, and the liquid storage cavity and the gas storage cavity are located on the sides of the two partitions that are far apart from each other.

[0009] A sealed storage box is installed inside the installation cavity. An absorption structure and a spraying structure are installed on the storage compartment. A locking component is installed inside the storage compartment and outside the sealed storage box.

[0010] The locking assembly includes a mounting frame fixed inside the storage compartment and located outside the sealed storage box. The mounting frame has multiple threaded rods internally connected to it. A strip-shaped groove corresponding to the threaded rods is provided on the outside of the sealed storage box near the bottom.

[0011] The spraying structure includes at least one water pump installed on the top of the storage chamber. The input end of the water pump extends into the liquid storage chamber through a hose. The top of the storage chamber and above the sealed storage box is equipped with a number of water spray plates equal to the number of water pumps. The output end of the water pump is connected to the water spray plates through a hose.

[0012] The absorption structure includes a fan installed on the top of the storage chamber. The output end of the fan extends into the gas storage chamber through a hose. An absorption air plate is installed on one side of the top of the storage chamber. The input end of the fan is connected to the absorption air plate through a hose.

[0013] The top of the inner side of the storage chamber is provided with an inclined surface for guiding the gas to the location of the absorption plate.

[0014] The storage compartment is fitted with a transparent glass panel on the outside.

[0015] Multiple water bladders are provided on the inner side of the storage compartment and on the side where the two partitions are close to each other. Multiple conical blocks that are compatible with the water bladders are assembled on the outer side of the sealed storage box.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention uses a water pump to spray the purification liquid into the installation cavity, which can quickly adsorb and neutralize toxic gases in the event of a hazardous chemical leak, and can also quickly absorb and preserve the emitted toxic gases to prevent further diffusion.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4 As shown, the emergency protection device for the combined land and water transport of hazardous chemicals includes a storage compartment 1. Partitions 2 are provided inside the storage compartment 1 and near both ends of the storage compartment 1. The two partitions 2 divide the interior of the storage compartment 1 into an installation cavity 3, a liquid storage cavity 4, and a gas storage cavity 5. The installation cavity 3 is located between the two partitions 2, and the liquid storage cavity 4 and the gas storage cavity 5 are located on the sides of the two partitions 2 that are far apart from each other.

[0026] A sealed storage box 6 is installed inside the installation cavity 3. The hazardous chemical is sealed and assembled inside the sealed storage box 6. Furthermore, a transparent glass plate 17 is provided on the outside of the storage compartment 1. The transparent glass plate 17 allows the user to observe the inside of the storage compartment 1. The transparent glass plate 17 is made of anti-fog and anti-scratch material (such as tempered glass or acrylic sheet) and can be detached and installed by means of buckles or slide rails, which facilitates regular cleaning to ensure the observation effect.

[0027] See attached document Figure 3A locking assembly is installed inside the storage compartment 1 and outside the sealed storage box 6. The locking assembly includes a mounting frame 7 fixed inside the storage compartment 1 and outside the sealed storage box 6. Multiple threaded rods 8 are threaded inside the mounting frame 7. An abutment block is fitted to the end of the threaded rod 8 near the sealed storage box 6. The abutment block can be made of rubber or the like. The surface of the abutment block is provided with anti-slip texture, which increases the friction between the abutment block and the sealed storage box 6 and prevents damage to the sealed storage box 6 due to excessive tightening of the threaded rod 8. A strip groove 9 corresponding to the threaded rod 8 is provided on the outside of the sealed storage box 6 near the bottom. A shock-absorbing rubber pad is laid in the strip groove 9 to further reduce shaking during transportation.

[0028] When locking the sealed storage box 6, the threaded rod 8 can be screwed on, and then the threaded rod 8 will gradually move towards the sealed storage box 6 and gradually abut against the sealed storage box 6. The bottom of the inner side of the storage compartment 1 is provided with a groove that matches the sealed storage box 6. The sealed storage box 6 is placed in the groove, so that when the sealed storage box 6 is subjected to the abutment force of the threaded rod 8, displacement is avoided.

[0029] Storage compartment 1 is equipped with a spraying structure, see attached diagram. Figure 1 and attached Figure 2 The spraying structure includes at least one water pump 12 installed on the top of the storage chamber 1. The input end of the water pump 12 extends into the liquid storage chamber 4 through a hose. The liquid storage chamber 4 and the hose are sealed together. The top of the storage chamber 1 and above the sealed storage box 6 are spray plates 13 with the same number as the water pump 12. The output end of the water pump 12 is connected to the spray plate 13 through a hose. Spray nozzles are provided below the spray plate 13.

[0030] When gas escapes from the sealed storage box 6, a sensor is installed in the mounting cavity 3. This sensor can be any of the following: an electrochemical sensor, a photoionization sensor, or an infrared sensor. When the sensor detects gas escape, a controller installed on the device controls the water pump 12 to drive it. This causes the water pump 12 to draw the purification liquid from the liquid storage cavity 4 through a hose and spray it into the mounting cavity 3, thereby reacting chemically with the escaped gas to reduce its toxicity.

[0031] Furthermore, if the hazardous chemical is cyanide, the purification solution can be sodium hypochlorite solution, hydrogen peroxide, etc., to decompose the cyanide into carbon dioxide and nitrogen gas. The specific formula is as follows:

[0032] NaCN + NaClO → NaCNO + NaCl

[0033] 2NaCNO+3NaClO+H2O→N2↑+3NaCl+2NaHCO3

[0034] If the hazardous chemical is an organophosphorus pesticide such as parathion or phorate, the purification solution can be sodium hydroxide solution, sodium carbonate solution, etc., to convert the organophosphorus pesticide into a less toxic product. The specific formula is as follows:

[0035] parathion + NaOH → p-nitrophenol + diethylphosphoric acid

[0036] This application is not limited to the two examples mentioned above, and can also be used to purify other leaked hazardous chemicals;

[0037] See attached document Figure 1 and attached Figure 2 An absorption structure is installed on the storage chamber 1. The absorption structure includes a fan 10 installed on the top of the storage chamber 1. The output end of the fan 10 extends into the gas storage chamber 5 through a hose. An absorption air plate 11 is installed on one side of the top of the storage chamber 1. The input end of the fan 10 is connected to the absorption air plate 11 through a hose.

[0038] In the event of a hazardous chemical leak, the aforementioned sensors and controller drive the blower 10, which collects the hazardous chemical gas through a hose and introduces it into the gas storage chamber 5. This isolates the gas from the gas in the sealed storage box 6, preventing leakage to the outside due to the limited sealing effect in the installation chamber 3. The blower 10 can also collect low-toxic or non-toxic gases generated during the spraying process, preventing disruption to the subsequent spraying effect. The gas storage chamber 5 is filled with an activated carbon adsorption layer or a chemical neutralizing agent (such as sodium hydroxide particles) to further adsorb or neutralize the introduced toxic gases. Furthermore, the top of the inner side of the storage chamber 1 is provided with an inclined surface 14 to guide the gas to the position of the absorption air plate 11. The inclined surface 14 guides the gas to the hose position at the input end of the blower 10.

[0039] See appendix Figure 4 Multiple water bladders 16 are provided on the inner side of the storage compartment 1 and on the side where the two partitions 2 are close to each other. Multiple conical blocks 15 that are compatible with the water bladders 16 are assembled on the outer side of the sealed storage box 6. With this arrangement, when a collision occurs during transportation, the sealed storage box 6 will cause the conical blocks 15 to be displaced by a huge force, causing them to puncture the water bladders 16. The water bladders 16 are filled with the same purification liquid as the liquid storage chamber 4, which can then chemically react with the hazardous chemicals in the sealed storage box 6, reducing their toxicity. Opening and closing plates are provided on the outer side of the storage compartment 1 at the positions of the installation chamber 3, the liquid storage chamber 4, and the gas storage chamber 5, for removing objects from inside the installation chamber 3, the liquid storage chamber 4, and the gas storage chamber 5.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
