Rotatable anti-rolling equipment

Abstract

The invention provides rotatable anti-rolling equipment, which comprises three groups of anti-rolling devices with the same structure and different sizes, each group of anti-rolling devices comprisesan outer shaft, an inner shaft and an anti-rolling plate, the outer shafts and the inner shafts are connected through supporting rods, outer gears are arranged at the two ends of the outer shafts correspondingly, inner transmission gears are arranged at the two ends of the inner shafts correspondingly, and the outer gears and the inner transmission gears on the same sides drive the outer gears andthe anti-rolling plates to rotate through transmission chains and driving of rotation of the inner transmission gears; and the three groups of anti-rolling devices are installed within the 1 / 3 of themiddle of a hull to 1 / 4 of the ship length, the distance between each group of outer shafts 3 is 1.5-2 m, the anti-rolling plate of the anti-rolling device in the middle group is wide, and the anti-rolling plates of the anti-rolling devices in another two groups are narrow. According to the rotatable anti-rolling equipment, the anti-rolling effect at various navigational speed can be ensured, meanwhile, various sea conditions can be taken into account, the anti-rolling effect under the severe sea conditions is ensured, and low resistance can be maintained in the calm sea conditions.

Description

technical field [0001] The invention relates to a novel rotatable anti-rolling device. Background technique [0002] Seakeeping of a ship refers to the ability of the ship to navigate under wind and wave sea conditions. Ship seakeeping has an important impact on ship navigation. On the one hand, the cargo movement caused by rolling may cause the ship to capsize. , propeller stall and a series of phenomena, thus affecting the navigation performance of the ship. [0003] The roll damping has a great influence on the roll of the ship. The traditional fin stabilizer cannot work effectively at zero speed and low speed. Although the appearance of the zero speed fin stabilizer solves this problem, it requires a large power, and The cost is expensive, and it is mostly suitable for high-value ships such as military ships. The anti-rolling water tank occupies too much space. The traditional bilge keel does not occupy the space and is cheap, but limited by the ship type, the width c...
