Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage repair, in particular to a leakage repair device for water supply and drainage pipelines. Background Art

[0002] Water has the function of promoting human metabolism, thereby helping the excretion of toxins from the human body. Therefore, water is an indispensable substance for the human body. Water needs to be transported to production and living areas through water supply pipes. When transporting water through pipes, the pipes are arranged below the ground. Steel pipes or iron pipes are needed to transport drinking water and sewage. However, due to long-term operation, water pipes will be damaged. Due to water pressure in the pipes, when a leak occurs, the water in the pipes will flow out of the pipes, causing waste of water resources and affecting water delivery. In order not to affect the water supply and drainage work and reduce the waste of water resources, it is necessary to inspect and repair the pipes as soon as possible. The existing technology has the following deficiencies: when repairing leaks in existing pipelines, the main method is to disconnect the water supply and then replace or weld the pipes to repair the leaks. However, the water supply and drainage work will be affected after the water is cut off. Therefore, a device that can directly repair the leak has appeared. The design structure of the existing leak repair transposition is complex, inconvenient to use, and the leak repair efficiency is low.

[0003] And in the application document with publication number CN217927783U, a water supply and drainage pipe leak repair device is mentioned. When using the device, the strap is located on the outside of the water pipe. After adjusting the tightening component to the leak point of the water pipe, the strap is fixed through the connecting component, and then the first screw is rotated. The first screw drives the pressure piece to move toward the strap, and the pressure piece presses the strap and the waterproof membrane at the leak point for waterproofing. The transposition design has a simple structure, low leak repair efficiency, and is easy to use, but there are still certain defects that need to be optimized. The specific defects are as follows: after long-term use, the waterproof membrane needs to be replaced, but the current design is not convenient for disassembly and replacement, and the tightening component is only applicable to one leak point.

[0004] Therefore, it is particularly important to design a water supply and drainage pipeline leak repair device to change the above technical defects and improve overall practicality. Utility Model Content
