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 pit

Embodiment 1

[0022] Such as Figure 1-2 As shown, the present embodiment provides a device for avoiding rudder turning and overturning, including a hull 1, a propeller 2 and a stern rudder 3 are arranged at the tail of the hull 1, and a liftable support frame 4 is arranged at the tail of the hull 1, Both ends of the support frame 4 are respectively connected with control baffles 5, and the free ends of the control baffles 5 are respectively connected to both sides of the hull 1 through drag cables 6. The control baffles 5 are provided with a number of openings. The combined control hole 51, when making a sharp turn with full rudder, the control baffle 5 can effectively unload part of the thrust of the stern rudder 3, which is more conducive to controlling the attitude of the ship, and completely solves the problem that the ship is prone to capsize during full rudder steering. The problem greatly improves the safety of the ship test and navigation process.

Embodiment 2

[0027] This embodiment provides a method for applying the device for avoiding rudder turning and overturning, which is characterized in that:

[0028] S1. When the ship sails forward normally, the support frame 4 is on the upper part of the slide rail, and the control baffle 5 is placed on the deck of the hull 1;

[0029] S2. When it is necessary to use the control baffle 5 to unload the thrust of the stern rudder 3 during the steering process of the hull 1, the support frame 4 is lowered along the slide rail, and the two control baffles 5 are respectively located on the left and right sides of the stern rudder 3 , the control hole 51 on the control baffle 5 is in an open state;

[0030] S3, when the stern rudder 3 is biased to the left, the control hole 51 on the control baffle plate 5 on the right side of the stern rudder 3 is closed, and part of the thrust of the stern rudder 3 is unloaded;

[0031] S4, when the stern rudder 3 is biased to the right, the control hole 51 on...

Abstract

The invention relates to the technical field of ships, and in particular relates to a device for preventing steering capsizing. The device comprises a ship body, wherein a proper and a stern rudder are arranged on the tail part of the ship body, a liftable supporting frame is arranged on the tail part of the ship body, two ends of the supporting frame are separately connected with a control baffle plate, a free end of each control baffle plate is connected to two sides of the ship body by virtue of a pull rope, anda plurality of control holes which can be opened and closed are formed in the control baffle plate. When in full-rudder sharp turn, the control baffle plate can effectively unload partial thrust of the stern rudder, the posture of the ship can be better controlled, the problem that the ship is easy to capsize in the full-rudder steering process is thoroughly solved, and the safety of the ship test and sailing process is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a device and method for avoiding rudder turning and capsizing. Background technique [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 lead to ship capsizing. 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 navigation field that is difficult to break thro...
