Combined ship anti-rolling device based on two-dimensional vector thruster and moving heavy objects

Abstract

The invention discloses a combined ship stabilizer based on a two-dimensional vector propeller and moving a heavy object, and relates to the ship stabilizer. Rolling propellers are connected with direct-current power motor shaft couplings through propeller swing rods, the direct-current power motor shaft couplings are connected with power motors through power motor brackets, and the power motor brackets are connected with swing motors through the direct-current power motor shaft couplings. The power motor brackets are installed on direct-current motor supporting platforms, rear power propellerbrackets are connected with front-back moving ship propellers, and guide rail heavy objects are installed on guide rails. The guide rails are installed on a profile platform, the direct-current motorsupporting platforms are installed on the left and right sides of the guide rails, and the front-back moving ship propellers which are used for a hull moving forth and back are installed on the two sides of the rear part of the swing motor. The profile platform is installed in close proximity to the direct-current motor supporting platforms on both sides, swing motor shaft couplings are connectedwith the swing motors, the swing motors are arranged on swing motor supporting platforms, and connecting pieces between the hull and a profile plate are arranged on the profile platform.

Description

technical field [0001] The invention relates to a ship anti-rolling device, in particular to a combined ship anti-rolling device based on a two-dimensional vector propeller and a moving heavy object. Background technique [0002] When a ship sails in sea waves, due to the influence of wind, waves, currents and other factors, it will produce six degrees of freedom of motion: roll, pitch, yaw, sway, surge and heave. Improper control of these movements will cause attitude instability and endanger the safety of ship navigation ([1]Perez T, Blanke M. Ship roll damping control[J].Annual Reviews inControl, 2012, 36(1):129-147) . The shaking of the ship when navigating in the river and sea is mainly rolling. In order to reduce the shaking of the ship, generally the hull will be modified and equipped with some anti-rolling devices. In some yacht-based luxury goods, comfort has become a very important indicator to measure the quality of a yacht. [0003] Fin stabilizer is currently...

Although the anti-rolling gyro has a better anti-rolling effect, it is technically more difficult and more expensive

[0006] Using the Coriolis effect when the weight moves in the radial direction in the rotating system, Hirakawa et al. ([3] Hirakawa Y, Hirayama T, Kakizoe K, et al. Sea trial of prototype Vertical Weight Stabilizer (VWS) from Yokohama National University in Japan anti-rolling system for small ships[J].Journalof Marine Science&Technology,2014,19(3):292-301) proposed a vertical gravity stabilizer system, and confirmed its effectiveness in ship model experiments, but lack suitable actuators, the practical application of the system is more difficult
