Document Type and Number:
WIPO Patent Application WO/2019/074039
Kind Code:
A1
Abstract:
A cleaning mechanism 3 cleans surfaces of tubes P included in a tube group Q while traveling in the tube group Q. The cleaning mechanism 3 is provided with a rotary shaft 32 that rotates about a prescribed rotation axis A, and a scraper 34 that removes substances adhering to the surfaces of the tubes P by coming into contact with the surfaces of the tubes P. The scraper 34 is connected to the rotary shaft 32 so as to be widened, by the centrifugal force of the rotary shaft 32, outward in the radial direction about the rotation axis A. When passing the tubes P, the scraper 34 comes into contact with the surfaces of the tubes P while the radial widening is changed in accordance with the surface shapes of the tubes P.
