ship anti-rolling device

Abstract

The invention proposes a ship anti-rolling device, which includes: tilting table, anti-rolling weight, waterproof elastic material, driving oil cylinder, bracket, oil pipe, working oil cylinder, working piston, pressing plate, fixed hinge support, slide rail, Hinge and drive rod. When the rolling motion occurs during the navigation of the ship, the pressure plate on the flooded side of the present invention will drive the anti-rolling weight on the deck to move to the non-immersed side under the action of water pressure, and then the left and right sides will be caused by the movement of the anti-swaying weight. The weight difference creates a moment that slows down the ship's roll. In addition, during the anti-rolling process, the anti-rolling heavy objects do not need to be controlled manually, and the degree of automation is high; compared with the traditional anti-rolling device, the device of the present invention will not cause additional flow resistance, so it will not bring additional energy consumption to the ship's 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 swings and yaw motions of ships is called ship sway, which is a harmful performance. Violent rocking movement will reduce the speed of the ship, cause cargo damage, destroy 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 external f...

AI Technical Summary

Problems solved by technology

When the ship rolls, the fin stabilizer can increase the lift by turning the angle of the fin angle to achieve ship stabilization, but the fin angle after turning it 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
