Device for restraining pure stability loss instability movement of ship

Abstract

The invention relates to the technical field of ships, in particular to a device for restraining pure stability loss instability movement of a ship. The device comprises two wing plates, the two wing plates are respectively mounted on two sides of a bow of a ship body, and the wing plates and the ship body are arranged in a clearance manner. When the ship body runs normally, the two wing plates are arranged above the water surface; and when the ship body performs large-amplitude rolling movement, the wing plates on the two sides are alternately immersed into water to generate upward lift force. The wing plates are fixed above the water surface by a certain distance, a certain wing attack angle is formed between the wing plates and the ship body, and resistance of the ship body during normal navigation is not affected. Only when the ship body generates large-amplitude rolling or overturning motion caused by pure stability loss, the wing plates are immersed into the water, forward rolling restoring moment is generated, and active control of the rudder is combined, so that the effects of restraining pure stability loss unstable motion and preventing overturning can be achieved, and the safety of the ship body sailing in waves is improved.

Description

Technical field [0001] The present invention relates to the field of ship technology, in particular, a device for constraining the pureness of the ship. Background technique [0002] Due to the unique configuration, the inner paradigm is caused by the limit instability movement caused by the inclusion of the inclined inclined incident, causing the sinking of the ship to cause serious threat to ship navigation safety. The transit device is only constrained in conventional rolling movement, and the limit instability caused by the pureness of the pureness loss cannot be restrained. Therefore, it is necessary to develop constraints for the limit large motion motion caused by this special instability mode. Inventive content [0003] In response to the disadvantage of the above existing production technology, it provides a device that constrain the pureness of the ship's pureness of the ship, does not increase the resistance of normal navigation, and when the ship is slightly hilt, it...

AI Technical Summary

Problems solved by technology

[0002] Due to the unique configuration of the inclination ship type, it is prone to extreme instability movement caused by the phenomenon of pure loss of stability in trailing waves and stern waves, which will cause the ship to sink and capsize, and pose a serious threat to the safety of ship navigation. The anti-rolling device can only restrain the conventional rolling motion, but cannot restrain the extreme instability motion caused by the pure loss of stability.
