Description

TECHNICAL FIELD

[0001] The utility model relates to ship anti-rolling technology field, concretely is a runner type small ship anti-rolling device. BACKGROUND

[0002] Ship motion control has been one of the core problems of ship maneuverability, due to the interference of sea waves, gales and other factors, the rolling of the ship body greatly limits the application of the ship. Therefore, it is of great significance to study how to minimize the negative effects of ship rolling and restore its balance at the fastest speed.

[0003] At present, the research and application of ship gyro anti-rolling device in Europe and the United States are in a leading position. For example: the Wartsila company of the United States launched a ship anti-rolling system named "EnergoFlow"; the Rolls-Royce company of the United Kingdom developed a ship anti-rolling system named "GyroActive", both of which realize the balance control of the ship through the control of hydraulic cylinders and other actuators, and then realize the anti-rolling effect. China Shipbuilding Industry Corporation also developed a ship anti-rolling device named "SSDG", which uses gyroscopes and accelerometers and other sensors to monitor the motion state of the ship, and adjusts the balance state of the ship through the control of hydraulic cylinders and other actuators to realize the anti-rolling effect.
