Abstract
The present disclosure relates to a device and a method for pipeline leakage detection. The device for pipeline leakage detection includes a metal powder storage box, a plurality of ribs, and a signal collection and processing device. The metal powder storage box is ring-shaped and made of insulating material, which is configured to be sleeved on a pipeline. Metal powder is stored inside of the metal powder storage box, and inner and outer peripheral walls of the metal powder storage box are of mesh structure, which allows the metal powder to be ejected from the metal powder storage box under the push of leakage fluid of the pipeline. The plurality of ribs are made of insulating material, which are distributed evenly along an outer peripheral wall of the metal powder storage box, and fixed on the metal powder storage box respectively, and a plurality of coils arranged in a layer are configured inside the plurality of ribs. The signal collection and processing device is connected to each coil for collecting and monitoring electromagnetic signal of each coil and obtaining leakage parameters based on the abnormal signal when an abnormal signal occurs. The present disclosure can well detect whether the pipeline leaks and obtain the leakage parameters efficiently, portably, and accurately in the case of leakage.
