Is pulled up by a pulling rope device, and the rotating blade 6a is lifted.
And the cleaning device 6 is allowed to flow downstream again to continue the cleaning. Thus, even if the cleaning device 6 is caught and stopped at any position in the drainage channel 1 while the inner surface of the drainage channel 1 is being cleaned by the cleaning device 6, it is possible to manually release the hooking and pull out. The same operation can be repeated any number of times, so that the cleaning device 6 can be caught in the drainage channel 1 and the drainage channel 1 can be effectively cleaned without becoming unusable. The cleaning device according to the present invention is constructed as described above. When the cleaning device is in a state of being almost stopped or in a stopped state, the rotary blade is remotely inclined to pursue. Since the rotating blades are pulled back from the upstream side by the reel device via the rope body, the inclination of the rotating blades is extended to the original state, and the rotating blades can be caused to flow downstream again to continue cleaning. Even if the cleaning device is caught and stopped at any position in the pipeline while cleaning the inner surface of the pipeline with this cleaning device, it is possible to manually release the latch and easily perform the same operation as many times as possible. The cleaning can be repeated, and the cleaning can be effectively performed without the cleaning device getting caught in the pipeline.
