Description

TECHNICAL FIELD

[0001] The utility model relates to the technical fields of pipeline detection, in particular to a pipeline anti-leakage detection device. BACKGROUND

[0002] The pipeline is an important component of the water system, and once leakage occurs, it will not only cause waste of water resources, but also threaten the stability and safety of the water system; pipeline leakage may cause toxic substances or harmful wastewater to leak into the environment, causing water pollution, so it is necessary to detect the anti-leakage of the pipeline before embedding.

[0003] The patent document with Chinese application number CN202122616801.9 "Building water supply and drainage pipeline anti-leakage detection device" discloses a building water supply and drainage pipeline anti-leakage detection device, which cooperates between the crossbar, the first spring and the rubber pad. When the user fixes the pipeline, the end of the pipeline is first pressed against the rubber pad, then the handle of the screw rod is rotated, the screw rod moves the sleeve, and in turn indirectly drives the lower pressing block and the rubber pad to move, and at the same time, the other end of the pipeline is pressed tightly during movement, and after being tightly pressed, the first spring is compressed by the external pressure, which always gives the rubber pad an elastic deformation force, ensuring that the rubber pad is tightly pressed against the end face of the pipeline to prevent leakage. The existing device solves the problem of insufficient sealing of the pipeline on both sides during work. However, the patent still has the following shortcomings: it can only detect single caliber pipelines and cannot detect multiple caliber pipelines, so a pipeline anti-leakage detection device needs to be designed.
