DEVICE FOR CLEANING INSIDE OF PIPE

PURPOSE:To provide the device capable of removing a solid deposit on the inner wall of a sewer pipe, etc., so that sludge is not stuck on the deposit. CONSTITUTION:Supporting members 5 and 5 are provided on the front and rear ends 4a and 4b of a casing 4 contg. an impact propeller 3 and extended longitudinally. A scraper 6 having the outer diameter almost equal to the inner diameter of a sewer pipe 1 is fixed to the front 5a of the supporting member 5A. The inner wall 1a of the pipe is scraped by the scraper 6 by the thrust of the propeller 3 to remove the deposit on the inner wall. The scraped deposit is extruded by the forward movement of the scraper and discharged at the succeeding pit. The deposit is sucked when a suction pipe is provided. Since the deposit on which sludge tends to stick is removed in this way, the frequency of cleanings is reduced.
