[0002] The plugging of municipal pipeline ports refers to the closing of the ports or openings of municipal pipelines to prevent the leakage of fluids or the entry of external substances. In municipal engineering, especially in the construction of sewage pipelines, it is often necessary to locally plug the sewage pipelines and pump out the water in the sewage pipelines to facilitate the operation of construction workers entering the sewage pipelines. The traditional sewage pipe plugging method only uses a plugging airbag for plugging. However, when the plugging airbag is actually used, if the inner wall surface of the pipeline is rough or has sharp edges, when the airbag enters the pipeline and expands, it may be damaged or even scratched by these uneven surfaces, and in severe cases, air leakage may occur, affecting the plugging effect of the pipeline. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a plugging device for municipal pipeline ports, which solves the technical problem that the traditional plugging equipment only uses an airbag to plug the pipeline, and the airbag may leak air, affecting the plugging effect.

One end of the plugging platform is fixedly installed with an air pump, and a guide air pipe is fixedly installed inside the plugging platform. One end of the guide air pipe is connected to the output end of the air pump, and the other end of the guide air pipe passes through the plugging platform and is connected to a plugging airbag. A fixing mechanism for clamping the pipeline is arranged at one end of the plugging platform close to the air pump.

[0005] Furthermore, the plugging platform is provided with a small head end and a large head end, and the circular surface diameter from the small head end to the large head end gradually increases. The plugging airbag is arranged at the small head end of the plugging platform, and the plugging airbag is set to be spherical. The air pump and the fixing mechanism are both arranged at the large head end of the plugging platform.

[0006] Furthermore, the fixing mechanism includes a plurality of sliding rods. A plurality of sliding grooves for the sliding rods to slide are opened at the end of the plugging platform, and a clamping rod is fixedly sleeved outside the sliding rods.

[0007] Furthermore, a rotating ring is rotatably installed at the end of the plugging platform. A plurality of limiting grooves are opened on the rotating ring, and the plurality of sliding rods are respectively inserted into the plurality of limiting grooves.

[0008] Furthermore, the clamping rod is set to be U-shaped, and an extrusion block is fixedly connected to one end of the clamping rod far from the sliding rod. <www.patentguru.com>

[0009] Furthermore, a hollow handle is fixedly connected to the inner wall of the swivel, the air pump is arranged inside the hollow handle, and the hollow handle is provided with anti-slip grooves.

[0010] By means of the above technical solution, the present invention provides a plugging device for a municipal pipeline port, which has at least the following beneficial effects:

[0011] 1. The utility model can achieve double-layer sealing of the pipeline by arranging the sealing airbag and the sealing platform, greatly reducing the probability of accidental water leakage or air leakage in the pipeline and optimizing the sealing effect of the equipment.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0020] In municipal engineering, especially in the construction of sewage pipes, it is often necessary to partially block the sewage pipes and pump out the water in the sewage pipes to facilitate construction workers to enter the sewage pipes for work. The traditional sewage pipe blocking method is to use a blocking airbag for blocking. However, when the blocking airbag is actually used, if the wall surface inside the pipe is rough or has sharp edges, when the airbag enters the pipe and expands, it may be damaged or even scratched by these uneven surfaces, which may cause air leakage in severe cases, affecting the blocking effect of the pipe.

[0021] To solve the defects of the above-mentioned blocking device during use, please refer to Figure 1-Figure 4 The utility model provides a blocking device for municipal pipeline ports, which can perform double-layer blocking of the pipeline through the blocking airbag 3 and the blocking platform 1, thereby enhancing the blocking effect of the device and allowing the device to be stably installed at the ends of pipelines with different diameters, thereby improving the practicality of the device. The blocking device is based on a blocking platform 1, one end of which is fixedly installed with an air pump 5, and the interior of the blocking platform 1 is fixedly installed with an air guide tube 2, one end of the air guide tube 2 is connected to the output end of the air pump 5, and the other end of the air guide tube 2 passes through the blocking platform 1 and is connected to the blocking airbag 3, which can be driven to inflate the blocking airbag 3 through the air guide tube 2. The blocking airbag 3 can be expanded to block the pipeline, and the blocking platform 1 is provided with a small head end and a large head end, and the diameter of the circular surface from the small head end to the large head end gradually increases. The blocking airbag 3 is provided at the small head end of the blocking platform 1, and the blocking airbag 3 is set in a spherical shape. The blocking airbag 3 is inserted into the interior of the pipeline, and as the blocking airbag 3 goes deeper, the sealing airbag 3 can be The blocking platform 1 is inserted into the pipeline until the outer surface of the blocking platform 1 is in contact with the edge of the pipeline. Since the diameter of the circular surface from the small end to the large end of the blocking platform 1 gradually increases, the blocking platform 1 can fit the inner wall of pipelines of different diameters, and can block the pipeline from the port of the pipeline. After the air pump 5 inflates the blocking airbag 3, the blocking airbag 3 gradually expands to fill the space inside the pipeline. As the blocking airbag 3 expands, its outer wall will fit closely with the wall surface inside the pipeline to form a sealed isolation, and the pipeline can be blocked from the inner wall of the pipeline. In conjunction with the fixing mechanism 4, the pipeline can be double-sealed, which greatly reduces the chance of accidental water leakage or air leakage in the pipeline and improves the sealing effect of the equipment.

[0022] When the plugging platform 1 is clamped at the end of the pipeline, the plugging platform 1 may be displaced and loosened, resulting in a gap between the outer wall of the plugging platform 1 and the port of the pipeline, affecting the plugging effect of the device. To solve this technical problem, a fixing mechanism 4 for clamping the pipeline is provided at one end of the plugging platform 1 close to the air pump 5. Both the air pump 5 and the fixing mechanism 4 are arranged at the large end of the plugging platform 1, that is, the fixing mechanism 4 is arranged outside the pipeline. The plugging platform 1 can be firmly fixed on the pipeline through the fixing mechanism 4. Among them, the fixing mechanism 4 is based on multiple sliding rods 42. Multiple sliding grooves 6 for the sliding rods 42 to slide are opened at the end of the plugging platform 1. The sliding grooves 6 are arranged as strip-shaped grooves. A clamping rod 43 is fixedly sleeved on the outside of the sliding rod 42. The clamping rod 43 is arranged in a U shape, which can provide a sliding space for the clamping rod 43 to avoid the sliding of the clamping rod 43 conflicting with the pipeline. And an extrusion block 44 is fixedly connected to the end of the clamping rod 43 far from the sliding rod 42. The synchronous sliding of multiple sliding rods 42 along the sliding groove 6 can drive the clamping rod 43 to slide. The synchronous sliding of multiple clamping rods 43 can realize the expansion and contraction actions. When multiple clamping rods 43 contract, they can带动 the extrusion block 44 to clamp the outer wall of the pipeline, tightly clamp the device at the end of the pipeline, realize the fixation of the device, prevent the plugging platform 1 from loosening, and ensure the sealing performance of the plugging platform 1.

[0023] To realize the synchronous expansion and contraction of multiple clamping rods 43, a rotating ring 41 is rotatably installed at the end of the plugging platform 1. Multiple limiting grooves 45 are opened on the rotating ring 41. Multiple sliding rods 42 are respectively inserted into the interiors of the multiple limiting grooves 45. The limiting grooves 45 are arranged as arc-shaped grooves. The positions of the sliding rods 42 in the sliding grooves 6 can be limited through the limiting grooves 45. Rotating the rotating ring 41 can change the positions of the limiting grooves 45. The limiting grooves 45 can drive multiple sliding rods 42 to slide synchronously along the sliding grooves 6, and further control the expansion and contraction of the clamping rods 43, which is convenient for clamping the device at the end of the pipeline and also convenient for removing the device from the end of the pipeline. And by controlling the contraction degree of the clamping rods 43, the device can be clamped on pipelines with different diameters, making the device applicable to pipelines with different diameters and further improving the practicality of the device.

[0024] To facilitate the control of the rotation of the rotating ring 41, a hollow handle 46 is fixedly connected to the inner wall of the rotating ring 41. The air pump 5 is arranged inside the limiting groove 45 to avoid the limiting groove 45 affecting the installation of the air pump 5. And anti-slip lines are arranged on the limiting groove 45. An anti-slip pad is installed between the end face of the rotating ring 41 and the plugging platform 1 to increase the friction between the rotating ring 41 and the plugging platform 1 and prevent the rotating ring 41 from automatically rotating. When it is necessary to control the installation and disassembly of the device, only need to manually rotate the hollow handle 46, and the rotating ring 41 can be rotated through the hollow handle 46.

[0025] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
