The invention provides a pulse eddy current detection device with a cleaning function. The pulse eddy current detection device comprises an electric trolley, wherein a first rotating shaft and a second rotating shaft are arranged at the front end of the electric trolley; a first rotating rod and a second rotating rod are arranged on the first rotating shaft, and are connected with a sheath; a brush is arranged on the outer surface of the sheath; a third rotating rod and a fourth rotating rod are arranged on the second rotating shaft, and are connected with a detection probe; a temperature detector and a pressure detector are arranged at the upper part of the electric trolley. The pulse eddy current detection device with the cleaning function has the following advantages: by the arrangement of the temperature and pressure detectors and an infrared obstacle avoiding sensor, detection of temperature and pressure in a pipeline is realized, and unnecessary damage to the detection probe is reduced; meanwhile, the sheath is mounted on the detection probe, so that on the one hand, the detection probe can be protected, and on the other hand, the effect of cleaning the inside of the pipeline can be achieved.
Description
technical field [0001] The invention belongs to the field of pulsed eddy current detection, in particular to a pulsed eddy current detection device with cleaning function. Background technique [0002] Pipeline corrosion has always been the primary factor that threatens the safety of pipeline network operation. Pipeline corrosion is in a state of being repairable and unpredictable all the year round. In-pipeline detection technology is a new detection technology in foreign countries in recent years. It uses geometric detection, magnetic flux leakage technology, pulse Eddy current and ultrasonic technologies detect the corrosion and cracks in the pipeline, and combine the principle of metal corrosion to predict the damage of the pipeline, so as to achieve the function of prevention and control; among them, the pulsed eddy current detection technology has its unique advantages, mainly including It has the advantages of strong agent, rich spectrum, fast response speed, and stro...
