PURPOSE:To clean the interior of a pipe efficiently using an extremely simple and low cost equipment. CONSTITUTION:A propeller 11 which is rotated by a water stream guided by a guide nozzle 8 is provided on the body of a device, then an arm 15 equipped with a brush 14 at the tip is installed on the rotating shaft 11a of the propeller 11 in a freely closing manner, and floating wheels 9, 19 are mounted on the device body. The propeller 11 is rotated by the riding of the device body over a water stream, then the brush 14 comes in contact with the inner surface of a pipe A through the arm 15 to do the cleaning job, and cleaning the intrapipe is performed more efficiently in proportion to a move rapid flow, without requiring a drive mechanism for cleaning. Thus, cleaning the intrapipe efficiently is done with such extremely simple and low cost equipment. |
