Abstract
The invention relates to a pipeline leakage detector, which is characterized in that the pipeline leakage detector comprises a sound collector (1), a sound adjusting amplifier (2) and an earphone receiver (3); the sound collector (1) transmits a collected signal to the sound adjusting amplifier (2) through a lead; and the sound adjusting amplifier (2) amplifies the received signal and conveys the amplified signal to the detection receiver (3). In this way, the pipeline leakage can be detected. The beneficial effects of the invention are that the collected underground pipeline waterdrop sound signal has no miscellaneous sound because the sound collector is against the ground of the underground pipeline tightly and seamlessly; the signal is transmitted to the sound adjusting amplifier; no signal loss occurs; and the leakage of the underground pipeline is determined by listening to the sound from a horn of the sound adjusting amplifier. In this way, the detector is practical, and the leakage detection of the underground pipeline is realized.
