PURPOSE:To easily and uniformly perform the removal of depositions and the carrying-out of the settled foreign matter over the total length of piping and to make noise small by providing a device with a screw, a screw driving motor, a battery and an ultrasonic and performing ultrasonic cleaning while the device travels by itself in liquid in the piping. CONSTITUTION:The ultrasonic self-traveling cleaning device for piping inside floats in liquid in the piping and is provided with a suction part 16 for sucking in liquid from the front, a screw 18 for discharging the liquid backwards and giving driving force for the self-traveling of a capsule 12, a screw driving motor 15 and a battery, a discharge part 17 for the liquid discharged backwards, an ultrasonic oscillator 14 for giving ultrasonic waves to the piping. The device gives ultrasonic waves while traveling by itself inside piping to subject the piping inside to ultrasonic cleaning and also the liquid is jetted from a discharge part 17 in the upper part of the capsule 12 to bring it into contact with the piping inside above the capsule 12, applying the vibration on the ultrasonic waves also to the liquid to perform ultrasonic cleaning. |
