Before detection, the motor 8 on the mounting block 7 can be started to drive the screw 9 to rotate, so that the scraping disc 10 moves back and forth on the screw 9 to clean the garbage and waste on the inner wall of the oil and gas pipeline, facilitating the ultrasonic detection probe 5 to perform better detection and improving the accuracy of the data. The bearing 14 can better connect the cleaning brush 15 with the motor 8 precisely, making the cleaning brush 15 fit tightly with the oil and gas pipeline and performing secondary cleaning on the inner wall to improve the accuracy of the detected leakage data. The driving body 11 drives the driving wheel 12 to move forward or backward, thereby driving the driven wheel 13 to move forward or backward, facilitating the all-round detection of the oil and gas pipeline.
