[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 to 2, an embodiment provided by the present utility model: an automatic plugging device for leakage of hazardous substances in chemical production, including a bottom plate 1. A plurality of support blocks 2 are fixedly connected to the top end of the bottom plate 1. The top ends of two of the support blocks 2 are fixedly connected to a first pipe 3, and the top ends of the other two support blocks 2 are fixedly connected to a second pipe 4. Here, the plurality of support blocks 2 can effectively support the first pipe 3 and the second pipe 4. The left side of the first pipe 3 is fixedly connected to the right side of the second pipe 4. The rear side of the top end of the bottom plate 1 is fixedly connected to a housing 5. The front left side of the housing 5 is fixedly connected to a sensor 6. Here, the sensor 6 can timely detect whether an accident of dangerous gas leakage occurs at the connection of the first pipe 3 and the second pipe 4. A driving component for providing power is fixedly connected to the inner wall of the housing 5. The driving component includes a motor 7. The rear end of the motor 7 is fixedly connected to the rear side of the inner wall of the housing 5. Here, the housing 5 can provide stable support for the motor 7 to make it rotate stably. The driving end of the motor 7 is fixedly connected to a main shaft 8. Here, the motor 7 can drive the main shaft 8 to rotate. The front side of the driving component is fixedly connected to a turntable 9. Here, when the main shaft 8 rotates, it can further drive the turntable 9 to rotate;

[0032] Two support rods 10 are rotatably connected to the front side of the turntable 9. The other ends of the support rods 10 are rotatably connected to sliding columns 11. When the turntable 9 rotates here, it can drive the two support rods 10 to rotate, thereby driving the two sliding columns 11 to move closer to the center along the grooves formed on the housing 5. The front sides of the support rods 10 are slidably connected to the front end of the inner wall of the housing 5. The outer parts of the sliding columns 11 are slidably connected to the front end of the inner wall of the housing 5. The front end of the sliding column 11 is fixedly connected to a crescent ring 12. When the sliding column 11 moves, it can drive the crescent ring 12 to move synchronously. A rubber pad 13 is fixedly connected to the outer side of the crescent ring 12. The inner side wall of the rubber pad 13 is in contact with the outer parts of the first pipe 3 and the second pipe 4. Here, the two rubber pads 13 move closer and form a closed loop after moving a certain distance to complete the plugging of the leakage of the first pipe 3 and the second pipe 4.

[0033] Refer to Figures 2 to 4 , a limiting ring 14 is fixedly connected to the outer side of the rubber pad 13. One end of the rubber pad 13 is fixedly connected to a spring 15. The other end of the spring 15 is fixedly connected to one side of the inner wall of the crescent ring 12. Here, the spring 15 enables the rubber pad 13 to be squeezed tighter against the first pipe 3 and the second pipe 4, thereby improving the plugging effect. A support component for maintaining the stability of the turntable 9 is fixedly connected to the bottom end of the inner wall of the housing 5. The support component includes two support columns 16. The bottom ends of the support columns 16 are fixedly connected to the bottom end of the inner wall of the housing 5. The top ends of the two support columns 16 are fixedly connected to a support ring 17. Here, the support columns 16 provide stable support for the support ring 17. The inner wall of the support ring 17 is rotatably connected to the outside of the turntable 9. Here, the support columns 16 and the support ring 17 can give the turntable 9 stable support to make it rotate stably without deviation.

[0034] On the left side of the top end of the bottom plate 1, there is a storage barrel 18 fixedly connected. On the inner wall of the top end of the storage barrel 18, there is a water pump 20 fixedly connected. One end of the water pump 20 is fixedly connected with a suction pipe 19. When a leakage accident occurs, the water pump 20 here will be responsive to the sensor 6, and thus the adhesive liquid inside the storage barrel 18 is pumped into the suction pipe 19. The output end of the water pump 20 is fixedly connected with a hose 21. One end of the hose 21 is fixedly connected to the inner wall of the limiting ring 14. The adhesive liquid in the suction pipe 19 will be further pumped into the hose 21, and then transmitted to the groove of the rubber pad 13, so as to carry out aftercare work on the leakage points of the pipeline 1 3 and the pipeline 2 4, and there is no need for staff to handle it, further improving the production efficiency of the chemical plant.

[0035] Working principle: When dangerous gas leaks at the connection of the pipeline 1 3 and the pipeline 2 4 supported by the bottom plate 1 and the support block 2, the sensor 6 immediately senses the leakage accident and sends a signal. After receiving the signal, the motor 7 starts and drives the main shaft 8 to rotate. The rotation of the main shaft 8 drives the turntable 9 to rotate, and then drives the sliding column 11 to move towards the center along the groove on the housing 5 through the support rod 10. The support pillar 16 and the support ring 17 here can provide necessary support for the turntable 9 when it rotates, making it rotate stably and preventing deviation. At the same time, the crescent ring 12 and the rubber pad 13 fixedly connected thereto also move accordingly until the two rubber pads 13 approach and form a closed loop to complete the sealing of the leakage point. During this process, the spring 15 ensures that the rubber pad 13 is in close contact with the outside of the pipeline, improving the sealing effect.

[0036] When the leakage is sealed, the water pump 20 starts to work in response to the sensor 6, pumping the adhesive liquid in the storage barrel 18 into the suction pipe 19. The adhesive liquid is transmitted to the groove of the rubber pad 13 through the hose 21, further strengthening the sealing effect and carrying out aftercare treatment on the leakage point, reducing the need for manual intervention, and improving the production efficiency and safety of the chemical plant.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
