<p><P>PROBLEM TO BE SOLVED: To efficiently clean the inside of a pipe even when level difference is formed therein. <P>SOLUTION: In the apparatus for cleaning the inside of a pipe, a rotary member 1 freely rotating around an axial center X along the longitudinal direction of a pipe is provided with support arms 2 in such a manner that the tip of each support arm is projected toward the inner face side of the pipe, and is provided with a contact member 3 which can be brought into contact with the inner face side of the pipe. Further, a driving unit 4 for driving and rotating the rotary member is provided so as to drive and rotate the rotary member in such a manner that each contact member comes in contact with the inner face side of the pipe along the circumferential direction of the pipe while moving the rotary member in the inside of the pipe, so that a substance deposited on the inner face of the pipe is removed. The support arms 2 are provided so as to be insertable into the pipe in such a manner that each of their tips faces the rear side in the moving direction in the inside of the pipe and is also projected to the inner face side of the pipe. The tips of the support arms inserted into the pipe are provided movably in the radial direction of the pipe, and further, each of the tips of the support arms is elastically energized toward the inner face side of the pipe. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
