The front upper cover and the front lower cover are snap-fitted to form a first cylindrical shell, and the rear upper cover and the rear lower cover are snap-fitted to form a second cylindrical shell. A cleaning mechanism is arranged at one end of the first cylindrical shell, and the other end of the first cylindrical shell is connected to the second cylindrical shell. A power unit is arranged inside the second cylindrical shell; the cleaning mechanism and the power unit are connected to a controller, and the cleaning mechanism, the power unit, and the controller are all electrically connected to a power supply device. The utility model is a pipeline inner wall cleaning device, which can solve the problem of long time consumption and low efficiency of manual pipeline dredging, and can perform efficient and convenient pipeline dredging and cleaning work.
