Description

Technical Field

[0001] The utility model relates to the technical field of pipe network inspection, in particular to a pipe network leakage inspection device. Background Art

[0002] When a pipeline leaks during use, it usually needs to be inspected and repaired to ensure the safe operation of the pipeline system.

[0003] A Chinese patent with application publication number CN216010441U discloses a heating pipe leakage detection device in a city's centralized heating network. In this patent, a detection mechanism is set up, which can not only detect the heating pipe to which it is attached, but also detect the vicinity of the heating pipe to which it is attached, thereby greatly improving the range of detecting heating pipe leakage. At the same time, the two detection methods also greatly improve the accuracy of the overall device in detecting heating pipe leakage, and the overall device can perform detection in one place for a long time, avoiding the situation where the staff can only perform detection after the heating pipe leaks.

[0004] When using the above patent, we found that the device is not convenient for detecting elevated pipelines. When the pipeline is installed higher through the support frame, it is inconvenient for the inspectors to detect the pipeline. Therefore, we proposed a pipeline network leakage inspection device.
