Abstract

A pair of expansion links each having a rotary jet nozzle are respectively expanded in the opposite two directions in synchronism with each other within a tank. With these link mechanisms capable of expansion and contraction, the link arms forming the links can be closed until the link arms are parallely adjoined to one another. The link mechanisms are driven by a driving shaft from outside the tank. The inner surface of the tank is scanned with streams of water sprayed from the nozzles along with the expansion of the expansion links thereby cleaning the inner surface of the tank.
