Description

Variable rudder of a ship {CONTROLLERABLE RUDDER OF A VESSEL}

The present invention relates to a variable rudder of a ship so that steering performance is excellent even when sailing at low speed or when sailing at high speed.

In general, ships are provided with rudders to divert the direction of travel, which are usually hydrofoils that rotate on a vertical axis, such as rudder stock, usually located behind the ship's propellers. By generating a transverse force, by deflecting the flow of seawater to the foil plane side to form a steering moment (centering the steering center) based on the center of gravity of the ship to change the direction of the ship.

As the rudder of such a ship becomes larger, the structural stability becomes important because the force required to change direction increases, and the area is proportional to the size of the ship. Accordingly, various structures and methods have been developed for rudder to improve steering performance and structural stability according to the size of a ship.

As described above, when the rudder of a ship according to the prior art is designed as a structure for improving steering performance at high speed, the steering performance is reduced at low speed, and when designed as a structure for improving steering performance at low speed, high speed Due to the poor steering performance at, it was difficult to design to satisfy both conditions.

The present invention has been made to solve the above problems, to have excellent steering performance in navigation at high speed as well as navigation at high speed.

In the rudder of the ship according to the present invention, in the rudder of the ship, a rudder body is installed in the hull to change the direction for steering, a variable member installed to protrude from the rudder body or inserted into the rudder body, And a variable drive for protruding from or being inserted into the rudder body.

The present invention reduces the area of the sea when sailing at high speeds and satisfies steering performance while reducing the impact on resistance. It also has the effect of enabling quick steering.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a side view showing a variable rudder of the ship according to the invention, Figures 2 and 3 is a side cross-sectional view showing a variable rudder of the ship according to the present invention. As shown, the rudder 100 of the ship according to an embodiment of the present invention is a rudder body 110 is installed on the hull 1, and a variable member 120 is installed to protrude or inserted into the rudder body 110. ), And a variable driver 130 protruding from or inserting the variable member 120.

The rudder body 110 is installed such that the rudder stock 111 coupled vertically to the upper side is installed at the rear of the propeller 2 from the hull 1 so that the direction is changed for steering of the hull 1, and the variable member therein. The mounting space 112 for installing the 120 is provided.

The variable member 120 is installed in the mounting space 112 of the rudder body 110 to protrude from the rudder body 110 or to be inserted into the rudder body 110, thereby expanding and reducing the area of the rudder 100, and When protruding to some extent from the 112, the locking portion 121 is formed at one end thereof so as not to be caught and separated from the rudder body 110.

The variable member 120 is slidably coupled back and forth to the mounting space 112 of the rudder body 110, for example, so that an operation protruding from the rudder body 110 and an operation inserted into the rudder body 110 are performed smoothly. .

Variable member 120 may be made of a single unit to be mounted on one side of the rudder body 110, as in the present embodiment is made of a pair to be installed on each side of the rudder body 110 in order to increase the variable range of the area.

The variable member 120 may be operated by a single variable drive unit 130 in the case of a pair, but may also be operated by each of the variable drive unit 130 in a pair as in the present embodiment, in which case the variable drive unit By operating independently of each other by the operation of the 130, the area of the rudder 100 can be minutely changed.

The variable drive unit 130 allows the variable member 120 to protrude from the rudder body 110 or to be inserted into the rudder body 110. When the variable member 120 is formed in a pair, the variable drive unit 130 is formed to be a single unit to form the variable member 120. It can be operated at the same time, it is made in a pair as in the present embodiment can operate the variable member 120, for example, it consists of a cylinder 131 installed inside the rudder body (110).

The cylinder 131 is formed of a hydraulic cylinder, but is not limited thereto, and may be formed of a pneumatic cylinder, and the piston rod 131a reciprocating by being fixed horizontally inside the rudder body 110 is provided at one side of the variable member 120. Connected.

On the other hand, the variable rudder 100 of the ship according to the invention guides the guide portion 140 provided in the rudder body 110 and the variable member 120 to guide the movement of the variable member 120 in the rudder body 110. It may further include.

The guide part 140 may include, for example, a guide protrusion 141 provided at any one of the rudder body 110 and the variable member 120, and the rudder body 110 and the variable member (slidably coupled to the guide protrusion 141). It may include a guide groove 142 provided in the other one of the 120, provided in the upper and lower sides of the rudder body 110 and the variable member 120, as in this embodiment, or alternatively in various locations 4, the guide protrusion 141 may be formed in the rudder body 110, and the guide groove 142 may be formed in the variable member 120. The guide protrusion 141 and the guide groove 142 may be reversed in its formation position.

Referring to the operation of the variable rudder of the ship according to the present invention having such a configuration as follows.

When the ship sails the ocean or sails at high speed, as shown in FIG. 3, the rudder 100 may be inserted into the rudder body 110 by the operation of the variable driver 130. Reduces the area of Due to the reduction of the area of the rudder 100, the resistance by sea water generated in the steering process of the rudder 100 is reduced, and stable steering is achieved.

In addition, when the vessel sails at a low speed to berth the port, as shown in FIG. 2, the variable member 120 protrudes from the rudder body 110 by the operation of the variable drive unit 130. Increase the area Therefore, in the case of low-speed navigation, even if the area of the rudder 100 increases, the resistance of the seawater applied to the rudder 100 is not a problem, but also enables precise steering or sharp steering.

In addition, regardless of the speed of the ship, in the event of an emergency, the rudder 100 is increased due to the protruding portion of the variable member 120 to enable rapid steering so that collision is avoided quickly.

In addition, the movement of the variable member 120 by the variable drive unit 130 is guided by the guide unit 140 to allow the variable member 120 to move stably in the rudder body 110 to improve the reliability of the operation. .

According to the embodiment of the present invention as described above, when sailing at high speed or when sailing at high speed to reduce the effect on the resistance while reducing the impact on the resistance, and when sailing at low speed or emergency Increasing the area allows for precise and fast steering.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. And will be included in the described technical idea.
