Abstract

The utility model relate to an underground pipeline detecting instrument. The main technical characteristics are that the detecting instrument includes a transmitter, a receiver, a signal comparison and analysis device, an image display device, and a voice prompt device; the signal comparison and analysis device, the image display device, and the voice prompt device are used with the transmitter and the receiver; the transmitter gives a signal current of a special frequency to a detected pipeline, and through utilizing the electromagnetic induction principle and detecting the magnetic field distribution of an underground pipeline, the accurate position, the direction, and the burial depth of the underground pipeline can be determined; the receiver adopts the three horizontal coil difference technology, so a received signal is stable and clear. The underground pipeline detecting instrument is reasonable in design, and the problem that a nonmetal probe must be used in the nonmetal pipeline detection is solved, so the underground pipeline detecting instrument can work normally. The underground pipeline detecting instrument has the advantages of high sensitivity, stable performance, strong anti-interference property, and deep detection depth. The underground pipeline detecting instrument provides convenience for the cable and pipeline reconstruction and extension maintenance, reduces excavated ground area, and saves man power, material resources, and time.

Description
