Liquid leakage detection device and liquid leakage detection method

Abstract

A liquid leakage detection device includes an isolation layer configured to warp around a pipe. A thin-film detection circuit is disposed on the isolation layer. The thin-film detection circuit includes at least one detection electrode loop. The isolation layer defines openings at positions corresponding to the at least one detection electrode loop. Whether a leakage occurs can be determined by obtaining a change in the resistance value of the detection electrode loop. Multiple liquid leakage detection devices can be connected in series and wrapped around a plurality of segments of a single pipe, or multiple liquid leakage detection devices can be connected in series and wrapped around multiple independent pipes one by one, thereby realizing liquid leakage detection of multiple pipe segments and directly locating the location of the leaky pipe in the event of a liquid leakage in the pipe, reducing the time and cost of liquid leakage detection.
