Description

Technical Field

[0001] The utility model relates to the technical field of hazardous chemicals, in particular to an emergency treatment device for leakage of hazardous chemicals. Background Art

[0002] In the continuous development of mankind, various chemicals are constantly produced, which has brought great convenience to human production and life. However, chemicals are generally stored in chemical storage tanks. Once the chemical storage tanks are damaged, it will cause great harm to people's lives and health. Therefore, plugging devices for hazardous chemical leaks came into being. In the prior art, plugging devices are often used to plug plane damage, while chemical storage tanks are often curved structures. Existing plugging devices cannot adapt well to fit different curved surfaces, resulting in a large amount of chemical leakage after plugging. To address the existing problems.

[0003] For example, a Chinese patent (publication number: CN113479504A) discloses a plugging device for transporting hazardous chemicals. The plugging device, by providing a hinge assembly, a rubber part, a sealing cover, and an adsorption mechanism, allows the device to be directly adsorbed on the damaged part of the surface of the transport device. The hinge assembly can adapt to fit the curved surface of the transport device, and cooperate with the rubber part and the sealing cover to make the sealing effect better, quicker and more practical. However, the above technical solution is a single-sealing structure when sealing the leak point. Due to the single-sealing structure, its plugging effect is poor.

[0004] Secondly, when barreled chemicals leak, due to the difference in internal and external pressure, the place where the chemicals leaked is prone to splashing, which leads to the leakage being directly sealed during the plugging process, causing the chemicals to splash toward the upper and lower ends, which can easily cause harm to personnel.

[0005] Therefore, an emergency treatment device for leakage of hazardous chemicals is proposed. Summary of the invention

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figures 1 to 7 , the utility model provides a technical solution:

[0038] An emergency treatment device for leakage of hazardous chemicals, comprising a container barrel 1, wherein an arc-shaped baffle plate 3 is slidably mounted on the circumferential surface of the container barrel 1, an arc-shaped plate 5 is slidably mounted inside the arc-shaped baffle plate 3, and a first airbag 6 is fixedly mounted on the inner circumferential surface of the arc-shaped plate 5; an adjusting rod 4 is rotatably mounted on the outer circumferential surface of the arc-shaped plate 5; a cavity column 7 is fixedly mounted inside the adjusting rod 4, and the left end of the cavity column 7 is located outside the adjusting rod 4 and passes through the arc-shaped plate 5 and the first airbag 6; a moving ring 8 is slidably mounted on the inner left end of the cavity column 7, a plurality of U-shaped grooves 81 are evenly arranged on the left end of the moving ring 8, and a rotating plate 82 is rotatably mounted inside the U-shaped groove 81; a second airbag 9 is arranged on the left side of the rotating plate 82, and a threaded head is arranged at the center position of the right end of the second airbag 9, and the threaded head rotates with the inner left end of the moving ring 8.

[0039] Two second screws 22 are rotatably installed at the upper opening of the arc baffle 3, and a ring 2 is slidably installed on the circumferential surface of the two second screws 22. Two first screws 21 are rotatably installed on the circumferential surface of the ring 2, and the adjacent end of the first screw 21 is located on the inner side of the ring 2. A convex sliding groove 31 is opened at the inner upper end of the arc baffle 3.

[0040] By adopting the above technical scheme, chemicals are generally stored in chemical storage tanks, and once the chemical storage tanks are damaged, it will bring great harm to people's lives and health, so the plugging device for dangerous chemical leakage came into being. In the prior art, the plugging device is often used to plug the plane damage, and the chemical storage tank is often a curved surface structure. The existing plugging device cannot adapt to fit different curved surfaces well; secondly, during the leakage of barreled chemicals, due to the difference in internal and external pressure differences, the place where the chemicals leak is prone to splashing, which leads to the direct sealing of the leaking place during the plugging process, which is easy to cause chemicals to splash toward the upper and lower ends, and thus easily cause harm to personnel; the structure of the device is as follows: it includes a container barrel 1 A circular ring 2 is slidably installed on the outer side of the container barrel 1, wherein two first screws 21 are rotatably installed on the circumferential surface of the circular ring 2, and the adjacent ends of the two first screws 21 are located inside the circular ring 2. Therefore, during use, the adjacent ends of the two first screws 21 can fit together with the outer circumferential surface of the container barrel 1 during rotation, thereby allowing the circular ring 2 to be in a fixed state. Secondly, two second screws 22 are rotatably installed on the upper end of the circular ring 2, and the lower ends of the two second screws 22 can rotate through the circular ring 2 and are located at the lower end of the circular ring 2, and the lower end of the second screw 22 is rotatably installed on the upper end of the arc baffle 3. During use, rotating the second screw 22 can allow the arc baffle 3 to move up and down in a straight line.

[0041] Secondly, the top of the arc-shaped baffle plate 3 is in a state of being in contact with the outer circumferential surface of the container barrel 1, so as to prevent the splashing of the chemical from splashing downwards during the blocking process, so as to avoid endangering the safety of personnel. Secondly, an adjusting rod 4 is rotatably installed on the circumferential surface of the arc-shaped baffle plate 3, wherein the left end of the adjusting rod 4 is located on the inner side of the arc-shaped baffle plate 3, and an arc plate 5 is rotatably connected to the end of the adjusting rod 4 located on the inner side of the arc-shaped baffle plate 3, and the outer circumferential surface of the arc plate 5 is rotatably connected to the adjusting rod 4, and a first adjusting rod 4 is fixedly installed on the inner circumferential surface of the arc plate 5. An airbag 6, secondly, a slide 51 is fixedly installed at the center position of the upper end of the arc plate 5, and a convex slide groove 31 is opened at the upper end of the inner part of the arc baffle 3, and the top of the slide 51 is slidably installed inside the convex slide groove 31; during use, the adjusting rod 4 can make the arc plate 5 bring the first airbag 6 close to or away from the outer circumferential surface of the container barrel 1, and under the restriction of the slide 51 and the convex slide groove 31, the arc plate 5 and the first airbag 6 can maintain a horizontal state during the movement, so as to avoid the arc plate 5 and the first airbag 6 from rotating synchronously with the adjusting rod 4.

[0042] In addition, the interior of the adjusting rod 4 is in a cavity state, and a cavity column 7 is fixedly installed inside the adjusting rod 4, one end of the cavity column 7 passes through the arc plate 5 and the first airbag 6, an air intake pipe 71 is arranged inside the cavity column 7, and a limiting ring 74 is fixedly installed at the left end inside the cavity column 7; the outer circumferential surface of the air intake pipe 71 is consistent with the inner diameter of the cavity column 7, and the interior of the air intake pipe 71 is in a cavity state and the two ends are through, and a plug 72 is slidably installed at the left end of the interior of the air intake pipe 71, and the left end of the plug 72 is located on the outside of the air intake pipe 71, and one end of the outer side A connecting ring 73 is fixedly installed on the circumferential surface, wherein the outer diameter of the connecting ring 73 is smaller than the inner diameter of the cavity column 7. Secondly, a plurality of springs 731 are fixedly installed between the connecting ring 73 and the left end of the air intake pipe 71. During use, the external air delivery pipe pushes the plug 72 to slide until it slides out of the interior of the air intake pipe 71, so that the external gas can pass through the air intake pipe 71 and enter the interior of the cavity column 7. Under the action of the spring 731, the plug 72 can be reset to block the left end opening of the air intake pipe 71 to prevent gas leakage.

[0043] In addition, a movable ring 8 is slidably installed at the left end of the cavity column 7 between the connecting ring 73 and the limiting ring 74, and a plurality of U-shaped grooves 81 are evenly opened at the left end of the movable ring 8, and corresponding rotating plates 82 are rotatably installed inside the U-shaped grooves 81, wherein the rotating plates 82 can form a cylindrical structure when combined together; secondly, a second airbag 9 is fixedly installed at the left end inside the movable ring 8, and the second airbag 9 is located inside the plurality of rotating plates 82.

[0044] When in use, the ring 2 is slidably installed on the outside of the container barrel 1. After moving to a suitable position, the two first screws 21 are rotated so that the end of the first screw 21 located on the inner side of the ring 2 can fit together with the outer circumferential surface of the container barrel 1, so that the ring 2 can be in a fixed state, and then the safety officer manually rotates the two second screws 22, and the lower end of the second screw 22 moves downward, so that the second screw 22 can move downward synchronously with the arc baffle 3, so that the splashed chemicals can splash downward after encountering the arc baffle 3, so as to avoid the chemicals splashing onto the body of the personnel and causing harm; after the arc baffle 3 blocks the splashed chemicals, at this time, the adjusting rod 4 is rotated, and the adjusting rod 4 can push the arc plate 5, the first An airbag 6 approaches the cracked part of the container barrel 1, and then, with the movement of the adjusting rod 4, the arc plate 5 can carry the first airbag 6 to seal the cracked part of the container barrel 1, and in the process of movement, the top sliding installation of the slide 51 is connected to the inside of the convex slide groove 31 to prevent the arc plate 5 from rotating synchronously with the adjusting rod 4; and in the process of movement of the adjusting rod 4, the cavity column 7 will move synchronously with it, so that the left end of the cavity column 7 can extend to the inside of the container barrel 1. After the left end of the cavity column 7 is located inside the container barrel 1, the safety officer uses the external air pipe to insert from the right end of the cavity column 7 to push open the plug 72, so that the plug 72 can slide to the left, so that the left and right ends of the cavity column 7 can be in a through state.

[0045] Then, gas is transported into the cavity column 7, so that the moving ring 8 at the left end of the cavity column 7 can move under the action of the gas, and in the process of movement, the rotating plate 82 will move synchronously, so that the rotating plate 82 gradually slides out of the cavity column 7, wherein the rotating plates 82 are combined together and the left end is located inside the limiting ring 74, and the second airbag 9 is located inside the rotating plate 82. Therefore, during the inflation process, the second airbag 9 will not hinder the movement of the moving ring 8, and when the moving ring 8 and the left end of the limiting ring 74 are attached together, the moving ring 8 The left end is located on the outside of the cavity column 7, and then, under the action of the gas, the second airbag 9 will be expanded. At this time, the rotating plate 82 can rotate, so as not to hinder the expansion operation of the second airbag 9. After the second airbag 9 is expanded, the cracked part of the inner wall of the container barrel 1 can be sealed, so as to achieve internal and external double sealing operations: compared with the traditional single-layer sealing on the market, the present device can seal the inner and outer walls of the container barrel 1 with the cooperation of the above-mentioned multiple structures, achieving a double sealing effect, further improving the sealing effect, thereby effectively improving the sealing efficiency of the device.

[0046] Specifically, such as 1 to Figure 7As shown, a slide 51 is fixedly installed on the upper end of the arc plate 5, and the upper end of the slide 51 is slidably installed inside the convex slide groove 31; an air intake pipe 71 is arranged inside the cavity column 7, and the inner diameter of the air intake pipe 71 is smaller than the inner diameter of the cavity column 7; a plug 72 is slidably installed on the left end of the inner part of the air intake pipe 71, and the left end of the plug 72 is located on the outer side of the air intake pipe 71, and a connecting ring 73 is fixedly installed on the left end of the plug 72; a spring 731 is fixedly installed between the right end of the connecting ring 73 and the outer side of the left end opening of the air intake pipe 71, and a limiting ring 74 is fixedly installed on the left end of the inner part of the cavity column 7.

[0047] By adopting the above technical solution, most of the plugging devices on the market use a shrinkable cable tie with a plugging plate for operation. This results in that when performing a plugging operation, when facing chemicals that are not sprayed, the above-mentioned traditional cable ties and plugging plates can perfectly perform the plugging operation. However, when facing some chemicals that are in a spraying state due to different pressure differences, when the above-mentioned device is performing a plugging operation, the chemicals will splash up and down after encountering an obstruction. On the one hand, it affects the field of vision of the construction workers. On the other hand, the chemicals splashing up and down are easy to splash onto the chemical protective clothing worn by the construction workers, which is easy to cause danger to the construction workers. Compared with the traditional blocking devices on the market, the device can make the sprayed chemicals splash downward after being blocked by the blocking rod under the action of the arc baffle 3, so as to avoid the chemicals splashing onto the body of the construction workers. During use, the safety officer manually rotates the second screw 22 to allow the arc baffle 3 to gradually move downward, and the sprayed chemicals will be sprayed onto the inner wall of the arc baffle 3 after encountering the arc baffle 3. Since the upper end of the arc baffle 3 is in a fit with the container barrel, the sprayed chemicals can only splash downward, thereby avoiding the situation where the chemicals splash upward, ensuring the safety officer's field of vision and personal safety.

[0048] Working principle: First, the ring 2 is slidably installed on the outside of the container barrel 1, and the two first screws 21 are rotated to fix the ring 2, and then the second screw 22 is rotated to move the arc baffle 3 downward.

[0049] Then, the adjusting rod 4 is rotated, and the adjusting rod 4 pushes the arc plate 5 and the first air bag 6 close to the outer circumference of the container barrel 1 to block the position where the chemical is sprayed.

[0050] Secondly, the cavity column 7 extends into the interior of the container barrel 1. At this time, the safety officer uses the head of the delivery pipe to push open the plug 72 to allow the gas to enter the interior of the cavity column 7, thereby allowing the moving ring 8 to move.

[0051] During the movement of the moving ring 8, the rotating plate 82 and the second airbag 9 will be located outside the cavity column 7, and then the second airbag 9 will be expanded under the action of the gas. At this time, the rotating plate 82 rotates, and the second airbag 9 can block the areas with large leakage on the inner wall of the container barrel 1, thereby achieving double blocking.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
