[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] During the production of hazardous chemicals, when a leak occurs, rescue efforts are carried out at the leak site by spraying. During the spraying process, chemicals will continue to leak. When a leak occurs in a production pipeline, there is pressure inside the pipeline, which may cause the chemicals to spray outward, resulting in large-scale pollution, increasing the damage caused by the leak and causing huge damage to the environment.

[0020] To this end, the present invention provides a leakage rescue device for safe production of hazardous chemicals. Figure 1-9As shown, it includes a chemical transport pipeline body 1, a metal mesh 2 is fixedly connected to the outside of the chemical transport pipeline body 1, and the metal mesh 2 uses 0.2mm metal wire. When the 0.2mm wire covers the outside of the chemical transport pipeline body 1, the vibration generated when the liquid flows through the inside of the pipeline is not easy to affect the mesh, so as to reduce the possibility of false alarms in daily use. At the same time, when encountering the pressure shock caused by the leakage of the chemical transport pipeline body 1, it will also break quickly, so that the leakage of the chemical transport pipeline body 1 can be detected more accurately; a protective shell 3 is provided on the outside of the chemical transport pipeline body 1; the protective shell 3 slides on the outside of the metal mesh 2; a sliding component is provided inside the protective shell 3; the protective shell 3 moves back and forth on the outside of the chemical transport pipeline body 1 through the sliding component; The puncture blocking component is located outside the protective shell 3; the puncture blocking component includes an internal limit mechanism, which is used in conjunction with the puncture blocking mechanism, and the sliding component includes a servo motor 4; the servo motor 4 is fixed to one side of the outside of the protective shell 3; the output end of the servo motor 4 is installed with a drive module 5; the outside of the drive module 5 is rotatably connected to two groups of pressure rollers 6; the pressure rollers 6 are installed with a double-headed universal joint 7 at one end away from the drive module 5; another group of pressure rollers 6 are installed at the other end of the double-headed universal joint 7; the pressure rollers 6 are installed with a fixed block A8 at one end away from the double-headed universal joint 7; the fixed block A8 is fixed to the protective shell 3 inside; the outer side of the pressure roller 6 is fixed with anti-slip grooves 9; the pressure roller 6 and the outer side of the chemical transport pipeline body 1 are in contact with each other, and the pressure roller 6 forms a clamp on the outer side of the chemical transport pipeline body 1 through the mutual cooperation of multiple groups of pressure rollers 6 and double-headed universal joints 7, so that the protective shell 3 can remain stable on the outside of the chemical transport pipeline body 1. At the same time, the driving servo motor 4 can also make the protective shell 3 move back and forth on the outside of the chemical transport pipeline body 1. The puncture and blockage component includes an electric guide rail module 10 inside; the electric guide rail module 10 is located on both sides of the outside of the protective shell 3; the electric guide rail module 10 is rotatably connected to the rotating adjustment ring 11, and the action of the electric guide rail module 10 The purpose is to make the rotating adjustment ring 11 rotate inside the electric guide rail module 10 to control the angle of the rotating adjustment ring 11. It is a prior art and is well known to those skilled in the art, so it will not be described in detail in this solution. A fixed block B12 is fixed to one side of the outer side of the rotating adjustment ring 11. An electric telescopic rod 13 is fixed to the inner side of the fixed block B12. A magnetic head 14 is fixed to the telescopic end of the electric telescopic rod 13. A sealing arc pad 15 is magnetically attracted to the outer side of the magnetic head 14. A solidifying liquid storage capsule 16 is fixed to one side of the outer side of the sealing arc pad 15. A puncture head 35 is fixed to the outer bottom of the sealing arc pad 15. The inner limit mechanism includes a sliding rod 1 7; the sliding rod 17 slides inside the sealing arc pad 15; the metal blocking net 18 is slidably connected to the outside of the sliding rod 17; an elastic connecting rope 19 is installed at the end of the sliding rod 17; the elastic connecting rope 19 is fixed to the magnetic head 14 at one end away from the sliding rod 17; a micro explosive 20 is installed inside the magnetic head 14, and diisocyanate and water are set on the outside of the micro explosive 20, and then the two substances are separated by a partition, and multiple groups of slide grooves 21 are opened on the inside of the rotating adjustment ring 11; a baffle 22 is slidably connected to the inside of the slide groove 21; a spring rod 23 is fixed to the inside of the slide groove 21; the baffle 22 slides on the outside of the spring rod 23.

[0021] When working, the device is connected to an external power supply and then connected to an external control device to control and drive the device.

[0022] The wire mesh 2 is attached to the outside of the chemical transport pipeline body 1. When the chemical transport pipeline body 1 leaks, the liquid inside the chemical transport pipeline body 1 will be ejected outward along the rupture, and the high-pressure airflow formed will cause the wire mesh 2 to break and damage. The external control device senses the damaged area of the wire mesh 2 to control the servo motor 4 to start working. The servo motor 4 drives the drive module 5 to work, so that the pressure roller 6 rotates inside the protective shell 3. At this time, the pressure roller 6 drives the double-headed universal joint 7 and the other set of pressure rollers 6 to rotate, so that the protective shell 3 is in the chemical transport The outside of the pipeline main body 1 moves back and forth. When the protective shell 3 moves to the damaged position of the chemical transport pipeline main body 1, the electric rail module 10 outside the protective shell 3 starts to work, driving the rotating adjustment ring 11 to rotate inside the electric rail module 10 to adjust the position of the fixed block B12 on the outside of the chemical transport pipeline main body 1, so that the fixed block B12 is facing the damaged part. The anti-slip groove 9 increases the friction between the pressure roller 6 and the surface of the chemical transport pipeline main body 1, making the rotating adjustment ring 11 more stable and reliable during the movement on the surface of the chemical transport pipeline main body 1.

[0023] At this time, the electric telescopic rod 13 is driven to start extending, and the magnetic head 14 at the bottom of the electric telescopic rod 13 pushes the sealing arc gasket 15 to approach the damaged part, so that the puncture head 35 pierces the damaged part of the chemical transport pipeline main body 1 until the sealing arc gasket 15 is tightly attached to the chemical transport pipeline main body 1. In the process of the sealing arc gasket 15 approaching the chemical transport pipeline main body 1, the solidified liquid storage capsule 16 will be squeezed and then ruptured, and the internal solidified liquid will flow out, sealing the area where the sealing arc gasket 15 and the chemical transport pipeline main body 1 are in contact with each other, and then begins to solidify, making the area where the sealing arc gasket 15 is connected to the chemical transport pipeline main body 1 tighter and more reliable, while improving the sealing performance of the sealing arc gasket 15 on the damaged part of the chemical transport pipeline main body 1, the firmness of the connection between the sealing arc gasket 15 and the chemical transport pipeline main body 1 is improved, so as to achieve rapid rescue of the leakage of the chemical transport pipeline main body 1, and reduce the occurrence of losses caused by untimely rescue.

[0024] When the sealing arc pad 15 is completely penetrated into the chemical transport pipeline body 1 to seal the leak, the micro explosive 20 is driven to start exploding, blowing up the partition separating the diisocyanate and water, causing the two substances to mix, thereby generating a chemical reaction to produce a large amount of carbon dioxide and polyurethane mixture. The chemical reaction equation is OCN-R-NCO+2H2O→NH2-R-NH2+2CO2↑. The generated carbon dioxide gas will push the sliding rod 17 through the sealing arc pad 15 and the puncture head 35 to enter the chemical transport pipeline body 1. The sliding rod 17 drives the metal blocking net 18 and the metal blocking net 18 to move into the chemical transport pipeline body 1. The metal blocking net 18 is tightly matched with the inner side of the sealing arc pad 15, that is, when the sliding rod 17 and the metal blocking net 18 are pushed into the chemical transport pipeline body 1 together, the metal blocking net 18 needs to be pushed internally. The expansion of the gas inside the magnetic head 14 pushes the sliding rod 17 and the metal blocking net 18 into the interior of the chemical transport pipeline body 1. At this time, the electric telescopic rod 13 is driven to start shrinking. The magnetic head 14 is magnetically connected to the sealing arc pad 15. At this time, the magnetic head 14 moves upward and separates from the sealing arc pad 15. The magnetic head 14 pulls the elastic connecting rope 19 to pull the sliding rod 17 back to the interior of the sealing arc pad 15. The metal blocking net 18 remains stationary due to the close fit with the interior of the sealing arc pad 15. It begins to expand outward under compression to form a metal net to seal the inner side of the damaged part of the chemical transport pipeline body 1, further increasing the firmness and reliability of the sealing arc pad 15 in sealing the damaged part of the chemical transport pipeline body 1. At the same time, the polyurethane mixture formed by the reaction will solidify to seal the connection between the sliding rod 17 and the sealing arc pad 15.

[0025] By using the sliding assembly, the puncture blocking assembly and the internal limiting mechanism, when the chemical transport pipeline main body 1 is damaged, the sealing arc pad 15 is quickly sealed at the damaged part through the sliding assembly, and then the metal blocking net 18 and the sliding rod 17 are sent into the interior of the chemical transport pipeline main body 1 through the internal limiting mechanism. By pulling out the sliding rod 17, the metal blocking net 18 forms a layer of metal net, which further reinforces the stability of the sealing arc pad 15, improves the practicality and reliability of the device, and enables rapid rescue of the leaking part when the chemical transport pipeline main body 1 leaks, reducing the large-scale pollution and damage to the environment caused by the splashing of dangerous chemicals due to pipeline damage.

[0026] For details, see Figure 1-Figure 2 、 Figure 4-Figure 5 、 Figure 8As shown, the middle part of the inner side of the rotation adjustment ring 11 is fixedly connected to the limit plate 24; the outer bottom of the limit plate 24 is fixedly connected to a connecting block 25, which is made of silicone material; the end of the connecting block 25 away from the limit plate 24 is fixedly connected to a rotating shaft 26; the outer side of the rotating shaft 26 is hinged with a sealing ring 27; the outer top of the sealing ring 27 is provided with a chamfer A28; the outer side of the baffle 22 is provided with a chamfer B29 near the chamfer A28; the chamfer B29 and the chamfer A28 are used in conjunction with each other. A liquid storage capsule 31 is fixedly connected to the inner side of the rotating adjustment ring 11; a puncture needle 30 is provided on the side of the baffle 22 close to the liquid storage capsule 31; the interior of the liquid storage capsule 31 is filled with silicate expansion sealant, and a plurality of release holes 32 are provided on the outer side of the baffle 22; a sealing strip 33 is fixedly connected to the outer side of the rotating adjustment ring 11; a sealing groove 34 is provided on the outer side of the rotating adjustment ring 11; the sealing groove 34 is arranged on the outer side of another group of rotating adjustment rings 11; the sealing strip 33 cooperates with the sealing groove 34.

[0027] During operation, when the flange at the pipe connection leaks, the two sets of protective shells 3 on the outside of the chemical transport pipe main body 1 approach each other, and the sealing strip 33 enters the sealing groove 34, so that the two sets of rotating adjustment rings 11 can seal the outside of the leaking flange, reducing the leakage of liquid from the flange at the connection of the chemical transport pipe main body 1. When one side of the protective shell 3 approaches the flange, the flange will squeeze the baffle 22, causing the baffle 22 to move inside the slide groove 21, and the puncture needle 30 on one side of the baffle 22 approaches the liquid storage capsule 31 inside the rotating adjustment ring 11, puncturing the liquid storage capsule 31. During the movement of the baffle 22, the gap between the outside of the baffle 22 and the surface of the chemical transport pipe main body 1 is large, which may cause the sprayed liquid to flow into the protective shell 3. Therefore, during the movement of the baffle 22, the sealing ring 27 is squeezed, and the chamfer A28 and The shape of the chamfer B29 is set so that the baffle 22 is in close contact with the sealing ring 27, and the sealing ring 27 is in contact with the surface of the chemical transport pipeline body 1. When the sealing ring 27 is squeezed, pressure is applied to the sealing ring 27, and the connecting block 25 begins to bend. During the bending of the connecting block 25, the sealing ring 27 is subjected to the downward pressure of the baffle 22 and begins to be in close contact with the surface of the chemical transport pipeline body 1. At the same time, due to the rotating shaft 26, the bending of the connecting block 25 will not affect the angle of the sealing ring 27. The silicate expansion sealant stored in the liquid storage capsule 31 begins to expand when it comes into contact with the air. The expanded fluid increases the release hole 32 and is ejected. The outside of the flange is temporarily blocked, and the release hole 32 is also blocked. Through the cooperation of the baffle 22 and the sealing ring 27, the possibility of the leaked liquid flowing into the interior of the protective shell 3 and causing damage to the parts inside the protective shell 3 is reduced.

[0028] To sum up, the problem of rescuing the leak by spraying in the process of dangerous chemical production is effectively solved. During the spraying process, the chemicals will continue to leak. When a leak occurs in the production pipeline, there is pressure inside the pipeline, which may cause the chemicals to spray outward, resulting in large-scale pollution, increasing the damage caused by the leak and causing huge damage to the environment.
