Title:
BALANCE MAINTENANCE DEVICE OF FLOATING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/019122
Kind Code:
A1
Abstract:
The present invention provides a balance maintenance device of a floating structure, comprising: a driving device which rotates a driving shaft; a first eccentric rotator which is positioned on the one side of the driving device, and is connected to the driving shaft to rotate around the driving shaft by the rotation of the driving shaft; and a second eccentric rotator which is positioned on the other side of the driving device, and is connected to the driving shaft to rotate around the driving shaft by the rotation of the driving shaft, wherein the second eccentric rotator rotates with a phase difference of 180 degrees from the rotation of the first eccentric rotator. Further, according to the present invention, the balance maintenance device of the floating structure comprises: a first driving device which rotates a first driving shaft; a first eccentric rotator which is positioned on the one side of the first driving device, and of which one end is connected to the first driving shaft so that the first eccentric rotator may rotate around the first driving shaft by the rotation of the first driving shaft; a second driving device which rotates a second driving shaft; and a second eccentric rotator which is positioned on the other side of the second driving device, and of which one end is connected to the second driving shaft so that the second eccentric rotator may rotate around the second driving shaft by the rotation of the second driving shaft, wherein the second eccentric rotator has a phase difference of 180 degrees from the rotation of the first eccentric rotator.
