Robot for monitoring deformation of drainage pipeline

The invention discloses a robot for monitoring deformation of a drainage pipeline, which comprises a pivot shell, a plurality of supporting legs are distributed around the pivot shell in an annular array, and a signal acquisition end is fixedly mounted at one end, far away from the pivot shell, of each supporting leg; the signal acquisition end comprises a pressure sensor, the pressure sensor is used for detecting pressure information in real time and transmitting the pressure information to the controller, and a directional wheel is fixedly mounted at the other end of the movable rod; at least one of the directional wheels is driven by a servo motor; the main rod is of a telescopic structure. According to the method, the pressure can be monitored, so that the deformation part of the pipeline can be found in time, compared with a traditional method for monitoring through a camera, the workload of workers is reduced, the workers only need to judge suspected areas and do not need to pay attention to internal in
