▎ 摘　　要

NOVELTY - The device has a walking mechanical leg (2) provided with four groups. Two sides of the walking mechanical leg are correspondingly set on two sides of a robot body (1). The sides of the robot body are located between two groups of the walking mechanical legs and provided with a transverse auxiliary anti-dumping mechanical leg (3). A front end of the robot body is provided with a radar sensor. A back part of the robot body is provided with a graphene storage battery group box (5). An upper part of a front part of the robot body is provided with a detection image collecting device (9). USE - Municipal engineering underground pipeline four-foot robot pipeline detecting device. ADVANTAGE - The walking mechanical leg makes the robot skid-proof and has good buffer effect when walking, for observing the condition in the pipeline conveniently, so that the robot can stably pass when meeting the small step position or high and low obstacles. The device is not easy to fall, and does not need to completely dredge the pipeline and can pass and detect, and ensures wider application range, uses the movable detection image collecting device and the high-brightness illuminating lamp to ensure wider detection field. The detection image collection device is provided with a metal protective cover, for avoiding dirty water above the underground, ensuring the disposable detection work by reverse traction metal safety rope, smoothly dragging the robot, and solving the emergency situation of the recovery abnormal working state robot. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for using a municipal engineering underground pipeline four-foot robot pipeline detecting device. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a municipal engineering underground pipeline four-foot robot pipeline detecting device. 1Robot body 2Walking mechanical leg 3Transverse auxiliary anti-toppling mechanical leg 5Graphene storage battery pack box 6Metal retaining ring 7Metal safety rope 8Horizontal searchlight 9Detecting image collecting device 10High brightness illumination lamp 14Detecting image collecting device cable 15High brightness illuminating lamp cable 16Storage battery door panel
