Embodiment Construction

[0017] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 and figure 2 As shown, the moment gyro stabilization device of the present invention is composed as follows. The gyro rotor 1 is fixed on the inner frame 4 through the bearings 2a, 2b, driven by the flat motor 3, and the flat motor 3 is also fixed on the inner frame 4. The inner frame 3 is fixed on the base 5 through trunnions 8a, 8b and bearings 7a, 7b on both sides, and can rotate (precess) around the trunnions. Damper (magnetic powder brake) 6, servo motor 9 and sensor 10 are respectively installed on both sides of the trunnion, and controller 11 receives the signal of sensor 10 through the line and controls the action of damper (magnetic powder brake) 6 and servo motor 9. The battery 12 supplies power to the device. Base 5 can be fixed on any position where the strength of the hull is sufficient.

Abstract

The invention discloses a ship torque gyro stabilizer. Gyroscopic torque is converted into restoring torque of a ship body. A gyrorotor is driven through a flat motor to rotate at a high speed to provide the gyroscopic torque, and the size of damping force outputted through a damper or rotating speed meter-adjustment procession speed of a servo motor can be adjusted by adopting a dynamic feedback mechanism, so that the gyroscopic torque can be converted into the restoring torque of the ship body to the great extent so as to achieve good stabilizing effect. The ship torque gyro stabilizer is simple in structure and convenient to mount; no modification is required for an existing ship when mounted, navigability and comfortableness of small ships can be improved easily, and popularization and application prospects are quite broad.

Description

technical field [0001] The invention belongs to the technical field of ship anti-rolling, in particular to the anti-rolling technology and method for small ships (less than 100 feet in length and less than 200 tons in displacement) using a gyro method. Background technique [0002] The swaying of the ship has a huge impact on the habitability, navigation and safety of the ship. The ship is most likely to roll at sea, and the swing amplitude is the largest, which has a serious impact on the life and work of the crew. Therefore, anti-rolling technology is particularly important for improving the performance of the ship, and the anti-rolling technology is mainly aimed at ship rolling. At present, the most commonly used anti-rolling methods mainly include bilge keel, anti-rolling water tank and three kinds of anti-rolling fins. [0003] The bilge keel is installed on the bilge of the ship along the length of the ship to increase roll damping. Unless the size of the bilge keel ...
