ANTI-ROLLING DEVICE CAPABLE OF VARYING THE PROTRUDED LENGTH OF A BILGE KEEL

摘要

PURPOSE: An anti-rolling device is provided to prevent damage to a bilge keel by minimizing the protruded length of the bilge keel through rotation, contraction, and folding motions.;CONSTITUTION: An anti-rolling device comprises a bilge keel(20). The bilge keel is installed along the longitudinal direction of the outer surface of a ship or a marine structure. A rotation unit(30) is coupled to one end of the bilge keel and reduces the protruded length of the bilge keel through rotation. The rotation unit has a motor(31), a transfer gear(32), and a rotation gear(33). The motor supplies driving force to the bilge keel. The transfer gear is connected to the motor. The rotation gear is coupled to the end of the bilge keel and transfers torque to the bilge keel.;COPYRIGHT KIPO 2012
