Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to an anti-seepage device for drainage pipes. Background Art

[0002] Drain pipes are an important component of the drainage system. The pipes in the urban drainage system are usually composed of multiple intricately connected and intertwined pipes, which play an important role in transporting and discharging water resources.

[0003] In the drainage system, pipes are usually buried in sections inside the tunnel, and then connected through fixing parts. Fasteners are used to dock the pipes during the connection process, and fasteners such as flanges are used. The connection requirements are high, and the airtightness of the connection must be ensured to prevent water from seeping out. When the tightening force of the fastening bolts does not meet the requirements during the connection, the airtightness of the pipe connection will be problematic, causing water inside the pipe to seep out and water to accumulate inside the foundation pit. At this time, the inside of the foundation pit needs to be drained, which is very troublesome. Therefore, we propose a drainage pipe anti-seepage device. Utility Model Content

[0004] In view of the above background technology, the prior art has the disadvantages and defects that water seepage is easy to occur at the pipe connection.

[0005] The utility model discloses a drainage pipe anti-seepage device, comprising a connecting pipe, the outer surface of the connecting pipe is fixedly connected with a fixing ring, the fixing ring is provided with a sealing groove inside, a sealing pipe is installed outside the connecting pipe, a fixing mechanism is installed outside the sealing pipe, a connecting piece is installed inside the sealing pipe, a sealing ring is fixedly connected to the inner wall of the sealing pipe, a sealing ring 1 and a sealing ring 2 are fixedly connected inside the sealing ring, and a supporting ring is installed outside the sealing pipe.

[0006] Furthermore, the inner wall of the sealing tube is slidably connected to the outer surface of the fixing ring, and the sealing tube and the fixing ring are connected and fixed by a connecting piece.

[0007] Furthermore, the fixing mechanism comprises a fixing plate, an outer surface of the fixing plate is fixedly connected to an outer surface of the sealing tube, a reinforcing rib is fixedly connected to the outer surface of the fixing plate, and an outer surface of the reinforcing rib is fixedly connected to the outer surface of the sealing tube.

[0008] Furthermore, a fixing screw is fixedly connected to the outer surface of the fixing plate, and a fixing bolt is threadedly connected to the outer surface of the fixing screw.

[0009] Furthermore, the outer surface of the fixed screw is slidably connected to a movable plate, and the outer surface of the movable plate is slidably connected to the outer surface of the fixed ring.

[0010] Furthermore, the outer surface of the fixed plate is fixedly connected to the limiting plate, the outer surface of the limiting plate is slidably connected to the inside of the movable plate, and the outer surface of the fixing bolt is slidably connected to the outer surface of the movable plate.

[0011] Furthermore, the sealing ring 1 is slidably connected to the inside of the fixing ring, the outer surface of the sealing ring 2 is slidably connected to the inside of the sealing groove, and the outer surface of the sealing ring is slidably connected to the outer surface of the fixing ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model cooperates between a fixing mechanism, a sealing ring 1, a sealing ring 2 and a sealing tube. First, the fixing mechanism can connect the sealing tube with the fixing ring. During use, a closed space is formed between the sealing tube and the connecting tube. At this time, the sealing ring 1 and the sealing ring 2 can seal the sealing tube and the fixing ring. The sealing groove and the sealing ring can perform multiple seals on the connection to ensure the airtightness of the connection and effectively prevent water seepage. The purpose of sealing the connecting tubes is achieved and the problem of loose connection and easy water seepage between the connecting tubes is solved.

[0014] 2. The utility model facilitates the installation of the sealing tube by providing components such as support rings. During installation, the support ring can lift the sealing tube to facilitate the installation and fixation of the fasteners. The staff does not need to lift the pipeline, and the installation is very convenient. By providing components such as limit plates, the limit plates can control the moving direction of the moving plate when the moving plate moves. When the fixing bolts are tightened with the moving plate, the moving plate will not be driven to rotate, and the sealing tube can be driven to be tightly connected with the connecting tube, which is conducive to better increasing the sealing effect of the sealing ring 1 and the sealing ring 2.
