Problems solved by technology

[0002] At present, military ships and civilian ships used in various countries in the world generally use vertical stern rudders to control turning and deceleration. When the ship is performing performance tests or avoiding obstacles such as other ships and reefs during high-speed driving, especially when the rudder is full , acts on the ship to produce heeling moment, heave force and pitching moment. Excessive force and moment increase the difficulty of ship attitude control in high-speed navigation and easily cause the ship to capsize. In ship technology and use In today's era, where both have been greatly developed, the issue of safety and security has become an increasingly important issue, and it has always been a major technical difficulty in the field of navigation.

Embodiment 1

[0019] Such as figure 1 As shown, the present embodiment provides a device for reducing the heel angle of a ship when turning, including a hull 1, a propeller 2 and a stern rudder 3 are arranged at the tail of the hull 1, and the left and right sides of the tail of the hull 1 are respectively arranged There is a control board 4 for unloading the thrust of the stern rudder 3, and the two control boards 4 are respectively connected to the hull 1 through a telescopic device 5. When making a sharp turn with full rudder, the control panel 4 can effectively unload part of the thrust of the stern rudder 3, which is more conducive to controlling the attitude of the ship, completely solving the problem that the ship is easy to capsize during the full rudder steering process, and greatly improving the ship's performance. Safety during testing and navigation.

[0020] Wherein, the telescoping device 5 can control the control panel 4 to be attached to the hull 1 , or extend backward to t...

Embodiment 2

[0024] This embodiment provides a method for applying the device for reducing the heel angle of the ship when turning, which is characterized in that:

[0025] S1. When the ship sails forward normally, the two control panels 4 are not stretched out, and are attached to the left and right sides of the hull 1 respectively;

[0026] S2, when the stern rudder 3 is deflected to one side, the control panel 4 on the other side opposite to it is stretched out under the drive of the telescopic device 5, and extends to the outside of the propeller 2;

[0027] S3, adjusting the angle between the control panel 4 and the hull 1 through the telescopic device 5;

[0028] S4. After the hull 1 rotates stably, retract the control panel 4 on the corresponding side through the telescopic device 5 .

Abstract

The invention relates to the technical field of ships, in particular to a device for reducing a transverse inclination angle of a ship during turning. The device comprises a ship body; a propeller and a stern rudder are arranged at the tail of the ship body; two control boards used for unloading thrust of the stern rudder are respectively arranged at the left side and the right side of the tail of the ship body; the two control boards are respectively connected with the ship body by a telescopic device. When the ship takes a sudden turn at full rudder, the control boards are capable of effectively unloading part of the thrust of the stern rudder, so that the ship attitude is better controlled, the problem that the ship easily turns over in a steering process at full rudder is thoroughly solved, and the safety of a ship test and a sailing process is greatly improved.
