Ship stabilization device

Abstract

A ship stabilization device provided by the invention comprises an inclined table, a stabilization weight, a waterproof elastic material, a driving oil cylinder, a support, an oil pipe, a working oil cylinder, a working piston, a pressing plate, a fixed hinge support, a sliding rail, a hinge and a driving rod. When a ship performs rolling motion in the sailing process, the pressing plate on the soaking side can drive the stabilization weight on a deck to move towards the non-soaking side under the action of water pressure, and then the weight difference between a left board and a right board is caused through movement of the stabilization weight, torque is formed, so the rolling degree of the ship is relieved. In addition, in the stabilization process, the heavy object does not need to be manually controlled, so the automation degree is high; and compared with a traditional stabilization device, the device does not cause extra flow resistance, so extra energy consumption cannot be brought to ship navigation.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a ship anti-rolling device. Background technique [0002] When a ship sails in the ocean, it will inevitably be affected by wind and waves. Under the influence of wind and waves and other factors, the performance of periodic horizontal and vertical swaying and yaw motion of the ship is called ship swaying, which is a harmful performance. Violent rocking movement will reduce the speed of the ship, cause cargo damage, damage the hull and machinery; deteriorate the seaworthiness and maneuverability of the ship; dizzy the crew on board, affect the work and life of the crew on board, and reduce the comfort of the ship. [0003] The rocking motion of a ship can be divided into motions with six degrees of freedom: roll, pitch, yaw, surge, sway, and heave. Among them, the roll motion is the most severe, and the roll degree of the ship is affected by its own conditions and exter...

AI Technical Summary

Problems solved by technology

When the ship rolls, the fin stabilizer increases the lift by turning the angle of the large fin angle to achieve ship stabilization, but the large fin angle will bring a large additional flow resistance, which will cause additional energy consumption of the ship. In addition , the fin stabilizer device is complex and expensive; the water tank stabilizer device requires more equipment, which shows that the device is more complicated and the cost is relatively high; Causes additional energy consumption of the ship
