An Anti-rolling System Based on Moving Slider

Abstract

The invention discloses a rolling-relieving system based on a moving slide block. The rolling-relieving system comprises a power part, a track frame part, the moving slide block and a control part; the control part is used for coordinating work of the whole system; the power part provides power for moving of the moving slide block in the track frame part; when the ship rolling angle is greater than a certain numerical value, the control part starts a servo motor, the servo motor drives the moving slide block to conduct reciprocating movement in the frame according to a certain period, ship sway damping is increased, and thus ship rolling is eliminated or relieved; and when the ship rolling angel is decreased to a certain numerical value, the servo motor is stopped, and the system stops working. The rolling-relieving system has the advantages of simple structure, small size, large rolling-relieving torque, rapid response and the like, and ship rolling can be effectively relieved or eliminated.

Description

technical field [0001] The invention belongs to the field of ship technical equipment, and relates to a ship anti-rolling device, in particular to a rolling-reducing device based on a moving slider. Background technique [0002] When a ship is sailing or stationary, it is inevitable to be affected by wind and waves to sway, including roll, pitch, heave and yaw, among which roll has the greatest impact on the ship. The roll of the ship not only affects the navigation of the ship, but also It is easy to cause dizziness of the crew and passengers, and even a ship capsizing accident in severe cases, which is extremely harmful. The ship anti-rolling device eliminates or reduces ship oscillation by increasing the sway damping or increasing the anti-wave heeling moment. The existing ship stabilization devices mainly include fin stabilizers, water tank stabilizers, gyro stabilizers, rudder stabilizers, bilge keels, etc. Among them, fin stabilizers and water tank stabilizers are rel...

AI Technical Summary

Problems solved by technology

The existing ship stabilization devices mainly include fin stabilizers, water tank stabilizers, gyro stabilizers, rudder stabilizers, bilge keels, etc. Among them, fin stabilizers and water tank stabilizers are relatively mature and widely used; and Compared with other types of anti-rolling devices, fin stabilizers have the advantages of high anti-rolling efficiency, small size, and light weight, and are widely used in high-speed small boats, but they have higher requirements for control systems and relatively high costs. The application on low-speed and large-tonnage ships is limited; the design principle of the anti-rolling water tank is relatively simple. A well-designed passively controllable anti-rolling water tank can achieve a 50% anti-rolling effect by adjusting the water flow velocity and phase in the cabin. The anti-rolling water tank occupies a large volume, consumes a lot of energy during the work process, and must be carried out simultaneously with the hull design. Its control system is provided by a professional supplier, and it is rarely used on real ships; It is different from the rolling cycle in order to achieve anti-rolling while maneuvering, but special steering gear needs to be designed, and its anti-rolling effect is much smaller than that of fin stabilizers. It is generally used together with fin stabilizers or water tanks; the anti-roll gyro has a structure It is relatively compact, does not increase navigation resistance, relatively low power consumption, and high efficiency. It is generally used on small ships such as luxury yachts and patrol boats. It also has potential demand on small warships that need to sail at full speed. The key technology is high-speed rotor bearing lubrication. And cooling, eliminating the vacuum in the rotor, etc., the price is relatively expensive

[0003] The existing mobile slider ship anti-rolling device has a small moving distance of the slider and a heavy slider, so the anti-rolling torque is small, the power required by the power system is large, and the response of the control system and the anti-rolling effect are not very ideal.
