Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, specifically a marine roll-damping gyroscope. Background Technology

[0002] During ship navigation, external factors such as waves and wind can easily cause the hull to roll, affecting navigational stability, passenger comfort, and operational safety. Existing technologies often employ hydraulic or mechanical gyro stabilization devices, which suffer from problems such as complex structure, large size, high energy consumption, and high maintenance costs. Furthermore, traditional gyroscopes often have an integrated flywheel and shaft, with externally mounted motors, resulting in a less compact overall layout and limiting their widespread application in small and medium-sized ships or vehicles. Therefore, there is an urgent need to develop a compact, energy-efficient, and easy-to-maintain marine roll-damping gyroscope to overcome the shortcomings of current practical applications. Utility Model Content

The flywheel assembly and the precession assembly are disposed on the inner side of the vacuum shell. The flywheel assembly includes a flywheel, a flywheel shaft, a flywheel bearing, a flywheel bearing flange, and a permanent magnet flywheel motor. The permanent magnet flywheel motor is disposed inside the flywheel, achieving internal motor installation. The flywheel shaft is fixed and does not rotate. The flywheel is connected to the flywheel shaft through the flywheel bearing and the flywheel bearing flange. The flywheel shaft is fixed to the precession assembly through a shaft fixing seat and is fixedly connected to the base through the precession assembly.

[0015] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0016] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0017] Please see Figure 1 and Figure 2In one embodiment of this utility model, a marine roll stabilization gyroscope includes: a base 15, a vacuum shell 7, a flywheel assembly, and a precession assembly. The vacuum shell 7 is disposed on the outer side of the base 15 and is integrally welded and sealed with the base 15 to form a vacuum cavity. The flywheel assembly and the precession assembly are disposed on the inner side of the vacuum shell 7, and the flywheel assembly and the precession assembly are all installed inside the vacuum cavity. The flywheel assembly includes a flywheel 3, a flywheel shaft 4, a flywheel bearing 2, a flywheel bearing flange 13, and a permanent magnet flywheel motor 1. The permanent magnet flywheel motor 1 is disposed inside the flywheel 3, realizing the motor is built-in. The flywheel shaft 4 is fixed and does not rotate, and is fixed by a shaft fixing seat 12. The shaft fixing seat 12 is fixedly connected to the inner ring of the precession motor bearing 5. The flywheel 3 is mounted on the flywheel shaft 4 through the flywheel bearing 2 and the flywheel bearing flange 13.

[0018] In one embodiment of this utility model, the precession assembly includes: a permanent magnet torque precession motor 6, a precession motor bearing 5, a precession motor rotor 14, and a precession motor stator 10. The permanent magnet torque precession motor 6 is a direct-drive structure with gearless and beltless transmission. The permanent magnet torque precession motor 6 is supported by the precession motor bearing 5. The precession motor rotor 14 is fixedly connected to the inner ring of the precession motor bearing 5. The precession motor stator 10 is connected to the base 15. The inner ring of the precession motor bearing 5 is connected to the flywheel assembly to support the flywheel assembly and enable flexible precession movement. A precession motor magnet 8 is provided between the precession motor rotor 14 and the precession motor stator 10. The precession motor magnet 8 is connected to the precession motor rotor 14. When the permanent magnet torque precession motor 6 is working, the precession motor rotor 14 and the entire flywheel assembly deflect together, thereby achieving precession.

[0019] In one embodiment of this utility model, the flywheel motor stator 11 and the flywheel motor magnet 9 are disposed inside the flywheel 3 and arranged coaxially with the flywheel 3. The flywheel motor stator 11 is fixed on the flywheel shaft 4, and the flywheel motor magnet 9 is fixed on the inner wall of the flywheel 3, thereby realizing a space-saving layout in which the motor is built inside the flywheel 3.

[0020] In this embodiment, when the ship rolls in the waves, the control system detects the tilt angle and angular velocity of the hull. Subsequently, the control system sends a command to the permanent magnet torque precession motor 6. This motor, as a precession motor, drives the precession motor rotor 14 to rotate in a direct drive manner, thereby applying a precise control torque to the entire flywheel assembly. According to the gyroscopic effect, the high-speed rotating flywheel 3 (driven by the built-in permanent magnet flywheel motor 1) will generate a gyroscopic torque (i.e., precession effect) opposite to the direction of the ship's roll when subjected to this control torque. This opposite torque acts on the base 15 through the precession motor bearing 5, and then on the hull, effectively resisting and offsetting the swaying caused by the waves, achieving the purpose of roll reduction and stabilization. The vacuum environment created by the vacuum shell 7 not only reduces the wind resistance loss when the flywheel 3 rotates at high speed, playing an energy-saving role, but also protects the internal precision components from the interference of the external environment (such as moisture and salt spray), ensuring the long-term stable operation of the system.

[0021] This marine roll-damping gyroscope achieves miniaturization, high efficiency, and high reliability. The flywheel shaft 4 is fixed and does not rotate, resulting in a more rational structure, longer service life, and lower maintenance costs. The permanent magnet flywheel motor 1 is built-in, with a compact layout and small size, making it widely applicable to various platforms such as ships and vehicles. It adopts a permanent magnet torque precession motor 6 for direct drive, with gearless and beltless transmission, resulting in high efficiency, energy saving, and simple maintenance. The vacuum shell 7 is fully sealed, waterproof and dustproof, energy-saving, and protects the internal mechanism, ensuring stable operation of the gyroscope in complex environments and effectively suppressing hull rolling.

[0022] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
