In the pipeline leakage detection sound pickup 1, the sound amplifying cover 11 is arranged, and the bottom of the sound amplifying cover 11 is provided with the opening 111, so that the outline of the opening 111 is adapted to the outer wall of the water supply pipeline; the pickup sensor 12 is mounted on the sound expansion cover 11, and the pickup sensor 12 is connected with the calculation processing device 2; the sound signals of different lengths of the water supply pipeline 100 are respectively monitored in real time through the plurality of leakage detection sound pickups 1, the collected sound signals are sent to the calculation processing device 2, the collected sound signals are processed and analyzed by the calculation processing device 2, the sound signals collected by the leakage detection sound pickups 1 are compared with preset water leakage sound signals, and then the intensity of the water leakage sound signals in the sound signals collected by the adjacent leakage detection sound pickups 1 is compared, so that the approximate position of a water leakage point on the water supply pipeline 100 can be determined. This pipeline adapter of leaking hunting 1 simple structure, the leakage condition that can online real-time supervision water supply pipeline 100, the convenient instant discovery leakage position reduces the loss that leaks and cause.

In order to reduce the noise of the sound signal collected by the pipeline leakage detection pickup 1, referring to fig. 2 and 3, in this embodiment, the leakage detection pickup 1 further includes an external wave-absorbing layer 13, and the external wave-absorbing layer 13 is attached to the outer side of the sound-amplifying cover 11; the sensing part of the sound pickup sensor 12 is arranged in the sound amplification cover 11. The external wave absorbing layer 13 is made of wave absorbing material and attached to the outer side of the sound amplifying cover 11 to absorb external sound waves, so that interference of the external sound waves on sound signals collected by the pickup sensor 12 is reduced, and accuracy of a water leakage monitoring result is improved.

Specifically, the calculation processing device 2 includes an amplification unit, a filtering unit, an a/D conversion unit, a calculation processing chip, and the like. The output end of the pickup sensor 12 is connected with the input end of the amplifying unit, the output end of the amplifying unit is connected with the input end of the filtering unit, the output end of the filtering unit is connected with the input end of the A/D conversion unit, and the output end of the A/D conversion unit is connected with the input end of the calculation processing chip.
