Description

Technical Field

[0001] The invention belongs to the technical field of ship anti-rolling devices and relates to a pulse-started ship anti-rolling flywheel device. Background Art

[0002] The anti-roll device is a device that uses the gyroscopic effect to achieve automatic stabilization. Its core technology lies in the high-speed rotating rotor. This rotor generates a torque to counteract the sway through its gyroscopic stabilization effect, thereby reducing the sway of the hull, aircraft and other means of transportation. In recent years, anti-roll devices have been particularly widely used in the field of ships. As ships are affected by factors such as wind and waves during navigation, the hull will sway, which not only affects the comfort of navigation but may also cause damage to the equipment and personnel on board. The anti-roll device can keep the hull stable, improving the safety and comfort of navigation.

[0003] At present, most of the actual solutions for ship roll reduction devices are gyro-type. The advantage of this design is that it can reduce the rolling and pitching directions at the same time. However, in fact, since most ships themselves are slender shuttle-shaped, firstly, the pitching amplitude is much smaller than the rolling amplitude, and the actual beneficial effect of reducing the pitching direction is not obvious. During the long-distance travel of the ship, the bow roll and yaw problems have a greater impact, and the traditional gyro-type roll reduction device cannot provide useful help; secondly, the traditional gyro-type roll reduction device must use a thrust bearing that can provide a large axial force during installation. This design wears quickly and has a relatively high friction energy consumption. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to solve the deficiencies in the prior art and to provide a pulse-started marine anti-roll flywheel device.

[0005] Technical solution: The present invention discloses a pulse-started marine anti-roll flywheel device, comprising a fixed bracket, a flywheel front cover, a flywheel rear cover, a flywheel shaft, a flywheel, a right bearing end cover, a left bearing end cover, a right support damping cylinder, a left support damping cylinder, a right support damping cylinder rod and a left support damping cylinder rod. The fixed bracket is fixed in a cabin at the center of the ship. The fixed bracket is provided with a front column bracket and a rear column bracket arranged front and rear along the bow direction. The outer shaft of the flywheel front cover is hinged in the shaft hole of the front column bracket, and the outer shaft of the flywheel rear cover is hinged in the shaft hole of the rear column bracket. The flywheel front cover and the flywheel rear cover are interlocked to form a vacuum spherical shell. The inner side of the flywheel front cover is uniform. There are evenly distributed front electromagnetic poles, evenly distributed rear electromagnetic poles on the inner side of the flywheel rear cover, and evenly distributed permanent magnet poles on the outer hub of the flywheel. When the ship is affected by wind and waves or ocean currents and causes bumps and shakes, the fixed bracket is driven to shake laterally, and the flywheel rotates at high speed along the left and right directions of the flywheel axis in the vacuum spherical shell. When the flywheel rotates at high speed, a large moment of inertia is generated. Through the energy transmission of the right support damping cylinder, the left support damping cylinder, the right support damping cylinder rod and the left support damping cylinder rod, the energy that drives the vacuum spherical shell to swing left and right and horizontally is consumed, which is used to greatly reduce the amplitude and frequency of the ship's roll and improve the heading stability.

[0007] A further improvement of the present invention is that the coils of the front end electromagnetic poles 1 to 8 and the rear end electromagnetic poles 1 to 8 have positive and negative poles. When the positive poles of the front end electromagnetic poles 1 to 8 and the rear end electromagnetic poles 1 to 8 are connected to a high level and the negative poles are connected to a low level, a forward current flows through the coils, and the magnetic pole end close to the inner side of the vacuum spherical shell is an S pole; when the positive poles of the front end electromagnetic poles 1 to 8 and the rear end electromagnetic poles 1 to 8 are connected to a low level and the negative poles are connected to a high level, a reverse current flows through the coils, and the magnetic pole end close to the inner side of the vacuum spherical shell is an N pole; when the positive and negative poles of the front end electromagnetic poles 1 to 8 and the rear end electromagnetic poles 1 to 8 are connected to a high level at the same time or the positive and negative poles are connected to a low level at the same time, the coils have no current, and the magnetic pole end close to the inner side of the vacuum spherical shell is an O pole, i.e., no polarity; The positive and negative poles of the front electromagnetic poles one to eight and the rear electromagnetic poles one to eight are respectively connected to an external high-frequency pulse voltage with a phase difference, and the direction of the magnetic poles in the vacuum spherical shell is constantly changing, driving the permanent magnet poles one to eight to drive the flywheel to rotate at high speed, and the high-speed rotation of the flywheel is achieved by increasing the frequency of the external voltage.

[0008] A further improvement of the present invention is that the right side support damping cylinder rod is telescoped inside the right side support damping cylinder.

[0009] A further improvement of the present invention is that the left side support damping cylinder rod is telescoped inside the left side support damping cylinder.

[0010] A further improvement of the present invention is that an upper double-fork ear plate is installed at the upper end of the right-side supporting damping cylinder rod, an upper ear axis plate is arranged on the outer side of the right bearing end cover, the upper double-fork ear plate is hinged to the upper ear axis plate, a lower double-fork ear plate is arranged at the lower end of the right-side supporting damping cylinder, a lower ear axis plate is arranged on the right side of the fixed bracket, and the lower double-fork ear plate is hinged to the lower ear axis plate.

[0011] A further improvement of the present invention is that an upper double-fork ear plate 2 is installed at the upper end of the left-side supporting damping cylinder rod, an upper ear axis plate 2 is arranged on the outer side of the left bearing end cover, the upper double-fork ear plate 2 is hinged to the upper ear axis plate 2, a lower double-fork ear plate 2 is installed at the lower end of the left-side supporting damping cylinder, a lower ear axis plate 2 is arranged on the left side of the fixed bracket, and the lower double-fork ear plate 2 is hinged to the lower ear axis plate 2.

[0012] A further improvement of the present invention is that the flywheel is installed in the center of the flywheel shaft, and the flywheel shaft is installed between the right bearing end cover and the left bearing end cover through a high-speed bearing, and the high-speed bearing is used to support the flywheel to rotate at high speed along the left and right directions of the flywheel shaft in the vacuum spherical shell.

[0013] A further improvement of the present invention is that the right bearing end cover is fixed to the right side of the vacuum spherical shell by a right bolt, and the left bearing end cover is fixed to the left side of the vacuum spherical shell by a left bolt.

[0014] Compared with the prior art, the pulse-started marine anti-roll flywheel device provided by the present invention achieves at least the following beneficial effects: When a ship installed with the present invention is sailing at sea and is affected by wind, waves or ocean currents to cause bumps and shaking, the fixed bracket will be driven to shake laterally. At this time, the flywheel is started, and the positive and negative poles of the front electromagnetic pole and the rear electromagnetic pole are respectively connected to an external high-frequency pulse voltage with a phase difference, resulting in the magnetic pole direction in the vacuum spherical shell constantly changing, thereby driving the permanent magnet magnetic pole to drive the flywheel to rotate, so that the flywheel rotates at high speed along the left and right directions of the flywheel shaft in the vacuum spherical shell where the flywheel front cover and the flywheel rear cover are fixed. The energy transmission of the right support damping cylinder, the left support damping cylinder, the right support damping cylinder rod and the left support damping cylinder rod can greatly reduce the amplitude and frequency of the ship's rolling, can replace the traditional gyroscopic anti-roll device, and improve the heading stability. At the same time, it has a good transmission ratio and friction characteristics, a compact structure and a long service life, thereby ensuring the comfort of the ship's navigation and avoiding damage to the equipment and personnel on board.
