Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection, in particular to a water conservancy pipeline leakage detection device. Background Art

[0002] Depending on the material, water conservancy pipelines can be connected by flange bolt connection, welding, thermal fusion and other methods. After long-term use of the pipeline, its interface is prone to leakage due to problems such as aging of seals, loose bolts, rusted welds or improper thermal fusion process.

[0003] A search revealed patent publication number CN220102893U, which discloses a pipeline leak detection device. This device seals the pipeline using a first notch and a second notch, creating a sealed cavity within the lower and upper shells. Two electrodes extend into the bottom of the lower shell. When a leak occurs, the two electrodes conduct. A detector detects this conduction and determines it is a pipeline leak. This information is then transmitted to a management platform via a wireless communication module, allowing for timely shutdown or scheduled maintenance. This structure allows for real-time leak detection via the leak detection device, and the detected information can be transmitted to the management platform after a leak occurs, making it more convenient to use.

[0004] Although the above solution can detect leaks through the detector and two electrodes extending into the bottom of the lower shell, due to the small coverage area of ​​the two electrodes, when only a slight leak occurs at the pipeline interface, it often takes a long time for the lower shell to collect leaked water sufficient to trigger the detector, and the occurrence of leakage cannot be detected in time, which needs to be improved.
