Problems solved by technology

The bilge keel has a simple structure, low cost and can play a certain anti-rolling effect, but it also has no anti-rolling effect at low speeds, and the anti-rolling efficiency is very low, which cannot meet the stability requirements of modern ships

Embodiment Construction

[0022] According to the structural characteristics of ships and ocean structures, an implementation example of an arrangement of magnetic fluid stabilizers on ships and ocean platforms is proposed.

[0023] The stabilizer is the obliquely inserted MHD stabilizer, which is mainly used for ships that require high stability and have buoys themselves. Such as: small waterplane area catamaran, high-speed wave piercing vessel, semi-submersible offshore platform, etc.

[0024] Such as figure 2 , 3 As shown, the stabilizers are arranged symmetrically in the buoys on both sides. It directly inserts the seawater pipeline (1) of the stabilizer into the underwater floating body obliquely, and the platform is disturbed by waves to produce a counterclockwise sway. At this time, the electrodes are energized, and the seawater moves under the action of electromagnetic force, and the reaction force is produces a clockwise torque. It includes a seawater pipeline (1), a superconducting magne...

Abstract

The present invention relates to one new kind of rock reducer with raised seaworthiness by means of magnetic fluid technology. The magnetic fluid rock reducer includes sea water pipe, liquid helium storage tank inside the sea water pipe of non-metal material, superconductive magnets homogeneously arranged on the outer wall of the pipe, and two, one positive and one negative, rock reducing electrodes inside pipe with the magnetic inducing line in the direction perpendicular to current direction. Through regulating the direction of current and magnetic field, sea water is made to move under the mutual action of current and magnetic field in sea water to produce one moment in the counter direction of ship rocking to reach the aim of reducing rocking. The present invention can reduce or eliminate the rocking of ship in wave, raise its seaworthiness and stability and improves the comfort of the ship.

Description

technical field [0001] The invention belongs to a novel anti-rolling device which applies the magnetic fluid technology to improve the seakeeping performance of ships, in particular to a ship-used internal magnetic magnetic fluid anti-rolling device. Background technique [0002] Modern ships generally have anti-rolling water tanks, anti-rolling fins and other devices to improve the seakeeping of ships. But they have the following defects and deficiencies: [0003] The anti-rolling water tank has a low anti-rolling effect and occupies a large volume of the cabin, which virtually increases the operating cost. [0004] Stabilizer fins are the most widely used anti-rolling form at present, and have relatively high anti-rolling efficiency, but their structure is complex, the cost is high, and they cannot achieve the anti-rolling effect at low or no speed. The bilge keel, also known as the anti-sway keel, is a simple device to reduce the sway of the ship. It is generally arran...
