The invention discloses an underground metal pipeline detector based on an electromagnetic induction mechanism, which comprises a detector shell of which the cross section is concave with a downward opening, a rack slidably sleeves the top wall of the detector shell, teeth are arranged on two side walls of the rack, a first spring is fixedly connected between the rack and the detector shell, a mounting block is welded to the bottom wall of the rack, a transmitting coil is fixedly connected to the lower surface of the mounting block, and two receiving coils are fixedly connected to the lower surface of the mounting block. The detector has the advantages that the transmitting coil and the receiving coil can be quickly collected into the detector shell for protection when a raised obstacle appears on a detection road surface, the detector is prevented from being damaged by the obstacle, automatic marking can be performed when a metal pipeline is detected, manual marking is avoided, time and labor are saved, the detection efficiency is greatly improved; meanwhile, the inclination angle and the extending length of the push rod can be adjusted according to different users, and the detector is suitable for different users.
Description
technical field [0001] The invention relates to the technical field of underground pipeline detection, in particular to an underground metal pipeline detector based on an electromagnetic induction mechanism. Background technique [0002] The pipeline detector can quickly and accurately detect the position, direction, depth of underground tap water pipes, metal pipes, cables, etc. One of the necessary instruments for water supply companies, gas companies, railway communications, municipal construction, industrial and mining, and infrastructure units for renovation, maintenance, and census of underground pipelines. Metal detectors are generally used for the detection of metal pipelines. Metal detectors are a high-performance There are three main types of metal detectors specially designed for security: electromagnetic induction type, X-ray detection type and microwave detection type, which are electronic instruments used to detect metal. [0003] In the prior art, when the ex...
