Description

Technical Field

[0001] The utility model relates to the field of ship accessories, in particular to a device for reducing the swaying and bumping of a ship. Background Art

[0002] The motion state of a ship when sailing in the ocean is one of the key difficulties in the ship's operational control performance. When it is sailing and working on the ocean, it will inevitably produce swaying motion due to the effects of ocean environmental disturbances such as sea breeze and waves. On the one hand, the swaying of the ship will affect the normal navigation of the ship and increase its navigation risk, while also causing adverse psychological and physiological effects on the crew and passengers; on the other hand, long-term swaying of the ship will have a bad impact on the ship's own structure, increase maintenance costs and reduce service life;

[0003] The anti-roll gyro has the advantages of being unaffected by the ship speed, compact structure, small space occupation, and good anti-roll effect. Therefore, it is increasingly widely used in the field of ship anti-roll. A heavy flywheel is installed inside the anti-roll gyro. The high-speed rotating flywheel has momentum and the precession physical effect of the gyro. The swaying motion of the hull causes the rotating flywheel to generate a precession torque, which pushes the flywheel and the rectangular frame to precess together. At the same time, the rotating flywheel generates an anti-roll torque during precession, which is transmitted to the hull through the rectangular frame and the base to suppress the swaying of the hull.

[0004] The flywheel is usually equipped with a winding harness for various purposes, including power supply. One end of the winding harness is fixed to the flywheel frame and is in a reciprocating swing state relative to the base, while the other end is fixed to the base and is relatively static. The winding harness repeatedly winds with the precession of the flywheel frame. After long-term use, the internal copper wire of the winding harness will be fatigued and broken due to repeated curling and bending, and the winding harness needs to be replaced regularly.
