Abstract:
PURPOSE: A balancing device of a floating body is provided to guarantee the stability of a floating body and to protect workers and equipment in the floating body by removing and reducing the fluctuation of the floating body. CONSTITUTION: A balancing device of a floating body comprises a pair of eccentric rotary units(U), a conveying device(460), and a driving unit(450). The pair of eccentric rotary units is arranged in a state of maintaining a phase angle difference at 180 degree to generate moment in the opposite direction of fluctuation of a floating body. Each eccentric rotary unit comprises a rotary body of which the center of gravity is eccentric and a driving shaft. The driving shaft rotates the rotary body. The conveying device is coupled to the eccentric rotary units to control a separation distance between the eccentric rotary units so that the moment can be controlled. The driving unit provides power to the driving shaft to rotate the rotary body.
