The invention discloses a sound wave receiving device for pipeline leakage detection, which is characterized in that a detection end magnetic strip of a detection mechanism is mounted on a pipeline wall to receive a pipeline sound wave signal, a stabilizing mechanism is mounted below the detection mechanism to fix a detection device, and after amplification and data processing are carried out according to the received sound wave signal, the sound wave signal is transmitted to the detection mechanism; the waveform of the sound wave signal is displayed on the frequency spectrum displayer and is sent out in a wireless transmission mode, the device is easy to apply, and detection points can be selected at will to measure the sound wave signal under the condition that drilling is not needed.
Description
Technical field [0001] The invention is the field of pipeline sound wave detection technology. It is a pipeline leakage testing device. Background technique [0002] In the process of pipeline transportation, due to the corrosion of pipelines, the quality of the pipeline material, and artificial destruction, it often causes pipeline leakage. Sound transmission is a method of pipeline leak detection. To detect whether the pipeline leakage is the most basic function, sound transmission is transmitted.The signal itself carrys a lot of information related to the leakage source, which can not only quantify the leakage volume, but also accurately locate the leakage position of the pipeline on the basis of a certain algorithm. [0003] At present, in the pipeline leak detection system based on sound launch, the traditional sound wave receiving device is mainly a wired device that drilled and installed on the wall of the pipeline. Not only is the installation method complicated, the dete...
