An easy-to-operate municipal underground pipeline partition construction device

Abstract

The invention belongs to the field of municipal construction, and particularly relates to a municipal underground pipeline partition construction device convenient to operate. The device comprises a columnar connecting part, the outer side walls of the two ends of the connecting part are fixedly sleeved with annular partition boards, round movable plates are arranged on the sides, away from the connecting part, of the annular partition boards, the round movable plates and the connecting part are in sealed connection through elastic rings, the side walls, close to the annular partition boards,of the round movable plates are fixedly connected with connecting rods, the ends, away from the round movable plates, of the connecting rods are fixedly connected with piston blocks made of magnetic materials, a mounting cavity is formed in the connecting part, an electromagnet is fixedly connected into the mounting cavity, the two sides of the mounting cavity are provided with sliding cavities communicating with the mounting cavity, and the piston blocks are arranged in the sliding cavities and are in sliding seal connection with the sliding cavities. Through the dual-layer seal elastic ring,the pipeline partition effect can be improved, placing is easy, the attaching degree of the device and the pipeline is high, and in addition, in the interior of the hidden with the dark light, the good warning effect is achieved.

Description

technical field [0001] The invention belongs to the field of municipal construction, and in particular relates to an easy-to-operate municipal underground pipeline partition construction device. Background technique [0002] Under municipal roads, various pipelines are often installed, such as drainage pipes, sewage pipes, etc., and cracks will appear in these underground pipelines during long-term use, especially at the joints of two pipelines. [0003] The construction workers usually weld the cracks manually, and they need to block and cut off the flow in the pipeline before construction. Once the blocking device is broken, the construction workers are easily flooded by fluid or even suffocated. There is a great security risk. [0004] The retrieved application publication number is CN 106958713 A, a construction device for partitioning municipal underground pipelines, which includes left and right splints symmetrically arranged and an airbag ring located between the lef...

AI Technical Summary

Problems solved by technology

[0006] 1. During the installation process of the device, it is impossible to ensure that the axis of the air bag ring coincides with the axis of the pipe, and the adjustment and placement are difficult;

[0007] 2. The device is only blocked by the air bag ring. Once the air bag ring is damaged, the fluid will break through the blocking device, causing serious consequences;

[0008] 3. The device does not have a warning device. Once the welding sparks are splashed on the airbag ring, it is easy to cause damage to the airbag ring.
