[0002] After years of operation, various pipelines may be damaged or leak due to corrosion, aging, poor operation and management, etc. Therefore, the pipelines need to be repaired to restore their functions and extend their service life.

[0003] During the pipeline repair process, repairs are often started while liquid is still flowing in the pipeline. Therefore, in order to facilitate the repair, the liquid in the pipeline needs to be diverted. However, sometimes the liquid in the pipeline flows at a high speed and has a large impact force, resulting in the diversion structure being unable to be quickly and effectively fixed, reducing the repair efficiency. At the same time, there is no universal diversion device for different pipelines, which makes the repair cost high. Utility Model Content

[0004] The purpose of the utility model is to provide a pipeline diversion structure for pipeline repair. During the repair, a fixing ring is inserted into the pipeline, and then the electric rod is started to push the top plate against the inner wall of the pipeline to fix the device. After the device is fixed inside the main pipeline, the rotating ring is rotated to make the baffle continuously move into the pipeline until it extends into the upstream of the damaged position. Then the air pump is started to inflate the airbag so that it is sealed with the pipeline after expansion, and then the pipeline can be repaired. The liquid in the pipeline is guided out from the outlet pipe. When the repair is completed, the top plate is retracted, the gas in the airbag is released, and the device is retracted. The diversion device is not only stable and easy to operate, but also can be applied to pipelines of different diameters, reducing the repair cost.
