Stabilizer suitable for low-speed ship

Abstract

The invention discloses a stabilizer suitable for a low-speed ship. The stabilizer comprises two rotating pillars, two rotatable supporting frames, a driving device and a control system, wherein the two rotating pillars are correspondingly and symmetrically mounted on the two sides of the bilge or the bottom of a ship body through the rotatable supporting frames, the rotating pillars are connectedwith a first transmission mechanism through an internally fixed connecting rod, the first transmission mechanism is driven to rotate by a first motor in a cabin, and the rotatable supporting frames are connected with a second motor in the cabin through a second transmission mechanism; and the two motors are fixed to a platform in the cabin and connected with the control system, and the rotating pillars are cones. Compared with an existing fin stabilizer, the stabilizer has the advantages that the structure is simple, installation is convenient, rolling of the ship can be reduced, and thus theship has good seakeeping performance. The stabilizer is suitable for the low-speed ship and marine structures which need to be moored at sea, such as scientific research vessels, fishing vessels andcargo ships.

Description

technical field [0001] The invention relates to an anti-rolling device, in particular to an anti-rolling device suitable for low-speed ships and marine structures requiring mooring operations at sea. Background technique [0002] As early as 1852, German physicist Heinrich Magnus proposed the Magnus effect, that is, when the rotational angular velocity vector of a rotating object does not coincide with the forward velocity vector of the object, it is perpendicular to the plane composed of the rotational angular velocity vector and the translational velocity vector A transverse force will be generated in the direction of . Under the action of this lateral force, the object's forward trajectory is deflected. The Magnus effect can be used to explain the curve ball in table tennis, the banana ball in football and other phenomena. Previous researchers used the Magnus effect to design sailboats with rotating cylinders that get propulsion from airflow around two large rotating cy...

AI Technical Summary

Problems solved by technology

At present, anti-rolling devices are widely used in the world, such as fin stabilizers, anti-roll tanks and bilge keels, among which fin stabilizers and bilge keels are mainly suitable for high-speed ships and their installation positions are limited, while anti-roll tanks can be used for Low-speed ships take up too much space on the hull and are expensive, so this patent invented an economical and reliable anti-rolling device suitable for low-speed ships
