Patent ID: 8042558

Claim:
A high-pressure water cleaning system, having a cleaning main body, the cleaning system being configured to eject high-pressure water from the cleaning main body to an object to clean the object, while moving the object at a constant speed with respect to the cleaning main body, comprising: a support frame member having a length which is larger than a width of the object, the support frame member being supported at extended end portions thereof at both sides by bearing units and eccentric rotational shafts extending in a direction perpendicular to a surface of an extended plane of the support frame member such that the support frame member is eccentrically rotatable, the eccentric rotatable shafts being configured to rotate to cause the support frame member to perform rotational motion; a plurality of high-pressure water ejecting nozzles which are arranged on the surface of the support frame member to be equally spaced apart from each other and are directed to face the object; and a drive device configured to cause the eccentric rotational shafts to rotate; wherein the high-pressure water ejecting nozzles are supplied with the high-pressure water through a water passage extending along the support frame member and are configured to eject the high-pressure water to the object being moved at the constant speed while performing the rotational motion.
