Zero-speed fin stabilizer with rotor

Abstract

The invention relates to a device for reducing the swaying degree of a ship when the ship is in navigation, in particular to a zero-speed fin stabilizer with a rotor. The zero-speed fin stabilizer with the rotor comprises a main fin blade, and one end of the main fin blade is connected with a main fin shaft. The zero-speed fin stabilizer with the rotor is characterized in that a first groove with an arc cross section is formed in the edge of the thick side of the main fin blade, and the first rotor which is longitudinally arranged is arranged in the first groove. A gap exists between the first rotor and the arc face of the first groove. The end, away from the main fin shaft, of the first rotor is connected with the main fin blade in a rotating mode. The other end of the first rotor is provided with a first driving device. The first driving device can drive the first rotor to rotate. The zero-speed fin stabilizer with the rotor can solve the problem that the fin stabilizer does not have the obvious stabilization effect on the ship in the low-speed and zero-speed conditions. The problems that the principal dimension of the ship is increased, the available space is reduced, stability is reduced, and the manufacturing cost of the ship is increased are solved, wherein the problems are caused by an additionally-arranged stabilization water tank.

Description

technical field [0001] The invention relates to a device for reducing the degree of shaking of a ship when the ship is sailing, in particular to a zero speed stabilizer fin with a rotor. Background technique [0002] When a ship is sailing, affected by external factors such as wind and waves, the hull usually rolls. In order to reduce the lateral shaking of the hull, anti-rolling devices will be installed on the ship. Fin stabilizer is currently the most effective and widely used anti-rolling device. Stabilizer fins are usually installed in the bilge of the two sides of the ship, and the section is wing-shaped, also known as side rudder. The fin stabilizer is rotated by the operating mechanism, so that the water flow exerts force on the fin stabilizer, thereby forming a stabilizer moment and reducing the roll of the hull, so as to reduce the roll of the hull. Since the fin stabilizers use the principle of hydrodynamics, the traditional fin stabilizers have a good anti-rol...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a zero-speed fin stabilizer with a rotor. The problem that the rolling effect is not obvious, avoiding the increase of the main scale of the ship, the decrease of the available space, the decrease of stability, and the increase of ship manufacturing cost caused by the addition of anti-roll water tanks
