Description

Technical Field

[0001] This application relates to the technical field of municipal pipelines, and in particular to a device for blocking the ports of municipal pipelines. Background Art

[0002] Municipal pipelines refer to various pipeline systems used in the construction and operation of urban infrastructure. They are mainly used for water supply, drainage, gas, electricity, communication, etc., to ensure the normal operation of the city and the convenience of residents' lives. These pipelines are usually buried underground, through which various substances and energies can be transported to meet the needs of different fields in the city.

[0003] Currently, the commonly used pipeline blocking devices are usually cover plates or single-body airbags. The cover plate is generally provided with a sealing ring to cooperate with the inner wall of the pipeline. The sealing ring is stuffed into the pipeline, and the cover plate abuts against the pipeline port for sealing. When using the cover plate for blocking, a large frictional force between the sealing ring and the inner wall of the pipeline requires heavy equipment such as excavators or bulldozers to forcibly insert (push) the sealing ring into the pipeline. During disassembly, the same heavy equipment such as excavators or tractors is also needed to forcibly pull the sealing ring out of the pipeline. The installation and disassembly are inconvenient and time-consuming and energy-consuming. The single-body airbag is mostly made of polymer materials such as rubber. When using the airbag, the airbag is placed into the pipeline and inflated. After the airbag expands, it abuts against the inner wall of the pipeline to achieve the blocking of the pipeline. However, during the use of the single-body airbag, an inflation device is required for inflation, which is time-consuming and energy-consuming. The frictional force between the inflated airbag and the inner wall of the pipeline is also likely to cause wear of the airbag, resulting in an unstable blocking effect of the pipeline blocking device.

[0004] Therefore, we propose a device for blocking the ports of municipal pipelines to solve this problem.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

A plug cover 5 is fixedly installed between the two connecting frames 4. A threaded cylinder 14 is fixedly installed on the side of the plug cover 5 close to the pipe body 1. A sleeve 6 is sleeved outside the threaded cylinder 14. The sleeve 6 is slidably matched with the threaded cylinder 14. Connecting plates 9 are fixedly installed on the four sides of the threaded cylinder 14. Two connecting rods 8 are hinged to the side of the four connecting plates 9 away from the sleeve 6. Support plates 7 are provided on one side of the four connecting plates 9. One side of the two connecting rods is hinged to the support plate 7. The four support plates 7 are in contact with the inner wall of the pipeline. A limiting mechanism is provided between the plug plate and the support plate 7. A driving mechanism is provided in the threaded cylinder 14; through the rotating shaft 3 and the connecting frame 4, the plug cover 5 can move and rotate at the same time, so that it can rotate to be parallel to the pipe body 1 when needed to plug the pipe body 1, and when not needed, it can rotate upward to move the plug cover 5 away to prevent affecting the water discharge of the pipe body 1. Through the four plug plates, the inside of the pipe body 1 can be abutted, so that the plug cover 5 is fixed at the port of the pipe body 1 and is not easy to move, and the plugging effect is stable.

[0022] Referring to Figures 3-4, the driving mechanism includes a screw rod 17, a rotating plate 16 and a motor. An installation groove is provided on one side of the sleeve 6 close to the threaded cylinder 14. A rotating plate 16 is rotatably installed on the side of the installation groove away from the threaded cylinder 14. A screw rod 17 is fixedly installed on the side of the rotating plate 16 close to the threaded cylinder 14. A screw rod 17 is fixedly installed on the side of the plug plate away from the pipe body 1. The screw rod 17 is in threaded connection with the threaded cylinder 14. A second motor 15 is fixedly installed on the side of the plug cover 5 away from the pipe body 1. The output end of the second motor 15 is in transmission connection with the screw rod 17, which can drive the sleeve 6 to move.

[0023] Refer to Figures 3-4 , the limiting mechanism includes a limiting block 12 and a limiting groove 13. Four limiting blocks 12 are fixedly installed on the side of the plug cover 5 close to the support frame. The limiting blocks 12 are in a T shape. Four limiting grooves 13 are opened on the side of the plug cover 5 close to the limiting blocks 12. The limiting blocks 12 are in sliding fit with the limiting grooves 13, which can limit the support plate 7.

[0024] Refer to Figure 2 , hydraulic cylinders 11 are fixedly installed on one side of the two chutes. The output ends of the hydraulic cylinders 11 are in transmission connection with the sliders 2, which can drive the sliders 2 to move.

[0025] Refer to Figures 1-3 , rotating shafts 3 are rotatably installed on the sides of the two sliders 2 away from the pipe body 1. One ends of the two rotating shafts 3 away from the sliders 2 are fixedly connected to a connecting frame 4. A first motor 10 is fixedly installed inside the slider 2. The output end of the first motor 10 is in transmission connection with the rotating shaft 3, which can drive the plug cover 5 to rotate.

[0026] Refer to Figures 3-4 , a sealing gasket is fixedly installed on the side of the plug cover 5 close to the pipe body 1. The sealing gasket is in contact with one side of the pipe body 1, which can seal one side of the pipe body 1.

[0027] The implementation principle of a municipal pipeline port plugging device in an embodiment of the present application is as follows: When in use, the hydraulic cylinder 11 can be started. The hydraulic cylinder 11 pushes the slider 2 forward until it moves to the end of the chute. Then, the first motor 10 is started. The first motor 10 drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the connecting frame 4 to rotate. The connecting frame 4 drives the plug cover 5 to rotate downward and be parallel to the pipeline body 1. Then, the hydraulic cylinder 11 is started again. The hydraulic cylinder 11 drives the slider 2 to move to the other side of the chute until the plug cover 5 completely enters the pipeline interior to plug the pipeline. The sealing gasket contacts one side of the pipeline to prevent water from overflowing. At the same time, the second motor 15 is started. The second motor 15 drives the screw rod 17 to rotate. While the screw rod 17 rotates, it drives the sleeve 6 to move away from the pipeline body 1. When the sleeve 6 moves, it drives the connecting plate 9 to move. The connecting plate 9 drives the connecting rod 8 to move. The connecting rod 8 drives the support plate 7 to move. The limiting block 12 enables the support plate 7 to slide within the limiting groove 13, so that the four support plates 7 contact the four sides of the inner diameter of the pipeline body 1, thereby fixing the plug plate.
