Description

Technical Field

[0001] The utility model belongs to the technical field of municipal water supply and drainage engineering, and particularly relates to a leakage detection device for municipal water supply and drainage engineering. Background Technique

[0002] A leakage detection device for municipal water supply and drainage engineering is a device used for a municipal water supply and drainage pipeline system to detect and locate possible leakage problems in the pipeline. It usually uses sound, vibration or other physical principles to identify abnormal phenomena in the pipeline, so as to judge whether there is leakage. When the pipeline leaks, the impact and friction of the water flow will generate specific sound signals. These sound signals are transmitted through the pipeline wall and change at the leakage point. The leakage detection device uses a highly sensitive microphone or sensor to capture these sound changes, and by amplifying, filtering and analyzing these signals, the leakage point can be identified. By using the leakage detection device for municipal water supply and drainage engineering, leakage points can be found and repaired in time, the water leakage rate of the water supply network can be reduced, and a large amount of water resources can be saved.
