Floating ash treatment mechanism in drainage pipeline

The invention discloses a floating ash treatment mechanism in a drainage pipeline, and relates to the field of drainage pipeline cleaning. The floating ash treatment mechanism comprises a pipeline, a shell, driving assemblies, a rotating assembly, cleaning assemblies and an air blowing assembly. The shell is slidably arranged in an inner cavity of the pipeline; the driving assemblies are fixedly mounted in the shell; the rotating assembly is rotationally connected to the right portion of the shell, and the driving assemblies are used for driving the rotating assembly to rotate; the cleaning assemblies are slidably connected to the side wall of the rotating assembly; the air blowing assembly is fixedly mounted at the end part of the rotating assembly; and the air blowing assembly is used for blowing out floating ash. Through the arrangement of the driving assemblies, pushing force of water flow is converted into driving force needed during rotary cleaning, manual operation is not needed, the mechanism is simpl
