Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical leakage sealing technology, specifically to an emergency sealing device for hazardous chemical leakage. Background Technology

[0002] Hazardous chemicals are widely used in industrial production, storage, and transportation, and are characterized by flammability, explosiveness, toxicity, and strong corrosivity. Once a leak occurs, it can cause serious environmental pollution, such as soil and water contamination, and may also trigger major safety accidents such as fires and explosions, posing a significant threat to human life. Leaks are prone to occur at the connection points of hazardous chemical output pipelines. With the development of the chemical industry and the increasing use of hazardous chemicals, the development of an efficient, reliable, and adaptable emergency sealing device for hazardous chemical leaks is urgently needed.

[0003] However, existing emergency containment devices for hazardous chemical leaks still have some problems in use:

[0004] First, when a leak occurs at a pipeline connection, it is usually sealed manually using simple tools. Manual sealing is slow and ineffective, and the leaked hazardous chemicals may also harm the operators, thus reducing the sealing effect of emergency sealing devices.

[0005] Secondly, existing emergency sealing devices have low flexibility. In actual operation, the position of the positioning plate used to install the sealing components cannot be flexibly adjusted according to specific sealing needs, thus affecting the sealing efficiency of the sealing device. Utility Model Content

[0006] In order to solve the problems of slow sealing speed, poor sealing effect and poor use flexibility of existing sealing devices, the purpose of this utility model is to provide an emergency sealing device for hazardous chemical leaks.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an emergency sealing device for hazardous chemical leaks, comprising an installation block, the installation block being fixedly installed on the outer surface of a pipeline, an adjustment component being provided on the upper surface of the installation block, a positioning plate being provided on one side of the adjustment component, a support plate being fixedly connected to one side of the installation block, an airbag sealing component being provided on the upper surface of the support plate and one side of the positioning plate, the airbag sealing component comprising a bidirectional air pump, the bidirectional air pump being fixedly installed on the upper surface of the support plate, a branch pipe being connected to the output end of the bidirectional air pump, a connecting air pipe being connected to the end of the branch pipe, and an airbag being fixedly connected to the end of the connecting air pipe through the positioning plate.

[0008] Preferably, the adjustment assembly includes a guide shell, which is fixedly disposed on the upper surface of the mounting block. A servo motor is fixedly mounted on one side of the guide shell, and the servo motor passes through the guide shell and is fixedly connected to a bidirectional screw. A slider is threaded on the outer surface of the bidirectional screw, and a moving rod is fixedly connected to one side of the slider.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application uses an airbag sealing component to facilitate rapid inflation of the airbag. The two airbags will deform according to the actual shape of the pipe connection, so that the airbags fit tightly with the connection and quickly seal the leakage point at the connection, replacing the traditional manual sealing and improving the sealing speed and effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides an emergency sealing device for hazardous chemical leaks, including an installation block 1. The installation block 1 is fixedly installed on the outer surface of a pipeline. An adjustment component 3 is provided on the upper surface of the installation block 1. A positioning plate 4 is provided on one side of the adjustment component 3. The setting of the adjustment component 3 facilitates the adjustment of the position of the positioning plate 4 for the sealing component. The positioning plate 4 is located on both sides of the pipeline. The cross-sectional shape of the positioning plate 4 is arc-shaped. The arc-shaped positioning plate 4 provides reliable support for the airbag 23 and also helps to guide the airbag 23 to more accurately cover the leak point when it is inflated, thereby improving the sealing effect. A support plate 5 is fixedly connected to one side of the installation block 1. The upper surface of the support plate 5 and one side of the positioning plate 4 are jointly provided with an airbag sealing component 2. The airbag sealing component 2 facilitates the rapid and effective sealing of the leak point at the pipeline connection, thereby improving the sealing effect of the sealing device.

[0020] The airbag sealing assembly 2 includes a bidirectional air pump 22, which is fixedly installed on the upper surface of the support plate 5. The bidirectional air pump 22 can quickly inflate the airbag 23 to achieve rapid sealing, and can also deflate after sealing. The output end of the bidirectional air pump 22 is connected to a branch pipe 21, and the end of the branch pipe 21 is connected to a connecting air pipe 24. The branch pipe 21 can evenly distribute the gas output by the bidirectional air pump 22 to the two connecting air pipes 24. The connecting air pipe 24 is a flexible hose, which gives it good flexibility and allows it to maintain its connection with the airbag 23 when the positioning plate 4 is adjusted. The end of the connecting air pipe 24 passes through the positioning plate 4 and is fixedly connected to the airbag 23, which facilitates the rapid inflation of the airbag 23 by the gas in the connecting air pipe 24.

[0021] The outer surface of the airbag 23 is coated with a rubber coating, which enhances the sealing of the connection between the airbag 23 and the pipeline, allowing the airbag 23 to fit more tightly to the pipeline leak after inflation, achieving rapid and effective emergency sealing. The airbag 23 is fixedly installed on one side of the positioning plate 4, and the stability of the airbag 23 during inflation and sealing is ensured by the support of the positioning plate 4.

[0022] The adjustment assembly 3 includes a guide shell 32, which is fixedly mounted on the upper surface of the mounting block 1. A servo motor 31 is fixedly mounted on one side of the guide shell 32, and a support frame 33 for use with the servo motor 31 is fixedly mounted on the other side of the guide shell 32. The servo motor 31 is fixedly mounted on the upper surface of the support frame 33, which in turn stably supports the servo motor 31, ensuring that it does not shake during operation. The servo motor 31 passes through the guide shell 32 and is fixedly connected to a bidirectional screw 37. By controlling the forward and reverse rotation of the servo motor 31, the rotation direction and speed of the bidirectional screw 37 can be precisely adjusted. A slider 36 is threaded on the outer surface of the bidirectional screw 37. The slider 36 is slidably connected to the guide shell 32. The slider 36 is threaded in the opposite direction of the thread on the outer surface of the bidirectional screw 37. The sliding connection between the slider 36 and the guide shell 32 ensures the stability and linearity of the slider 36's movement. When the bidirectional screw 37 rotates, the two sliders 36 move towards or away from each other along the axial direction of the bidirectional screw 37.

[0023] Furthermore, a movable rod 34 is fixedly connected to one side of the slider 36, which facilitates the movement of the slider 36 and drives the movable rod 34 to move. A limiting groove 35 is symmetrically opened on one side of the guide shell 32 to cooperate with the movable rod 34. The movable rod 34 is slidably connected to the limiting groove 35. The limiting groove 35 plays a limiting and guiding role in the movement of the movable rod 34. One end of the movable rod 34 is fixedly connected to the positioning plate 4. The movement of the movable rod 34 drives the positioning plate 4 to move, and the position of the positioning plate 4 can be flexibly adjusted to facilitate subsequent sealing work.

[0024] Working principle: First, the entire device is fixed to the outer surface of the pipe by mounting block 1, providing a stable foundation for subsequent operations.

[0025] Then, the position of the positioning plate 4 is adjusted by adjusting component 3, and the servo motor 31 is started. The output shaft of the servo motor 31 drives the bidirectional screw 37 to rotate. When the bidirectional screw 37 rotates, it drives the slider 36 to move in opposite directions along the guide shell 32. The movement of the slider 36 drives the moving rod 34 to move. The limiting groove 35 plays a role in limiting and guiding the movement of the moving rod 34. The moving rod 34 drives the positioning plate 4 to move. According to the actual situation of the pipeline, the positioning plate 4 used to install the sealing component is adjusted to a suitable position to prepare for the subsequent work of the airbag sealing component 2.

[0026] When a leak occurs at the pipe connection, the airbag 23 is deflated, and the airbag sealing component 2 starts working, activating the bidirectional air pump 22. The output gas is evenly distributed to the two connecting air pipes 24 through the branch pipe 21. The gas enters the airbag 23 through the connecting air pipes 24. The rubber coating on the outer surface of the airbag 23 can enhance its sealing at the pipe connection. As the airbag 23 inflates, it deforms according to the actual shape of the pipe connection and fits tightly against the pipe leak, thereby achieving rapid sealing of the hazardous chemical leak point.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
