This application has the advantage of being suitable for pipes of different thicknesses by setting up a trough body, an L-shaped block, a first threaded rod, a clamping block, a first turning handle, a second threaded rod, a second turning handle, a clamping block, a first electric telescopic rod, a rotating shell, a partition, a second electric telescopic rod and a cleaning brush for coordinated use, thereby solving the problem that the existing dredging ship mud pipe cleaning device is not suitable for pipes of different thicknesses, cannot be adjusted according to the thickness of the pipe to be cleaned, is not convenient for cleaning pipes of different thicknesses, and reduces the applicability of the device; Prior art 2 (application number 202323276679.0, a Chinese patent published on July 30, 2024) A mud pipe cleaning device, comprising a mud discharge hose, a mud discharge hard pipe and a hard mud discharge port, the mud discharge hard pipe and the hard mud discharge port are respectively fixed at both ends of the mud discharge hose, and also include a clamping end cover, a cleaning rod, an air guide channel and a cleaning disk, the clamping end cover is clamped on the hard mud discharge port, and the cleaning rod axially passes through the clamping end cover and extends to the inside of the mud discharge hose. In this application, when the end of the cleaning rod extends into the mud discharge hard pipe, an inflation device is used to inflate the air guide channel. At this time, the gas enters the cleaning disc through the connecting hole to expand the cleaning disc and finally the cleaning disc abuts against the inner wall of the mud discharge hard pipe. At this time, the cleaning rod is pulled out to the outside of the mud discharge hose.
