An anti-rolling device for a ship in a moored state

Abstract

The invention aims at providing anti-rolling equipment for ships in a mooring state, which comprises two anti-rolling devices and a rope. The rope is arranged on a ship; each end of the rope is connected the anti-rolling device arranged below water; the anti-rolling device comprises a framework, two baffles and two expansion links; supporting ends of the two baffles are symmetrically installed on the left end and the right end of the framework through a rotating shaft; hanging ends of the two baffles are respectively connected with the two expansion links; and each expansion link is connected with the framework through a respective angle shaft. The anti-rolling equipment has the characteristics that the structure is simple, the weight is light, the anti-rolling equipment does not occupy too much ship space, the cost is low, the anti-rolling equipment is convenient to operate, can be controlled in a passive mode or an active control mode, can be widely applied to conducting anti-rolling operation on common ships, and can be particularly applied to small ships below dozens of tons.

Description

technical field [0001] The invention relates to a small ship, in particular to an anti-rolling device for the small ship. Background technique [0002] At present, the devices used for ship stabilization in the world mainly include the following types: fin stabilizers, bilge keels, and water tanks for stabilization. The bilge keel is a passive anti-rolling device installed on the left and right sides of the bilge; the fin stabilizer is an active anti-rolling device. At medium and high speeds, the required control moment countermeasures are generated through the relative speed between the fin and the fluid. The disturbance moment of waves on the ship; in the mooring or zero speed state, the required control moment is generated by actively slapping the water surface. The device has a good anti-rolling effect in the moving state, but in the mooring state, The shaking effect is slightly poor, and the energy consumption is large, and the price is expensive, so it cannot be widel...

Problems solved by technology

The bilge keel is a passive anti-rolling device installed on the left and right sides of the bilge; the fin stabilizer is an active anti-rolling device. At medium and high speeds, the required control moment countermeasures are generated through the relative speed between the fin and the fluid. The disturbance moment of waves on the ship; in the mooring or zero speed state, the required control moment is generated by actively slapping the water surface. The device has a good anti-rolling effect in the moving state, but in the mooring state, The shaking effect is slightly poor, and consumes a lot of energy, and the price is expensive, so it cannot be widely used on general ships. It is mainly used in the field of ships, luxury yachts and other ships.

The anti-rolling water tank is another anti-rolling device, which forms the required control moment by controlling the flow of water in the tank. However, whether it is a passive water tank or a controllable passive water tank, its layout on the ship needs to be consistent with the hull. The structure is coordinated and takes up a lot of space
