Technical Field [0001] The present invention relates to a marine rudder linkage and flap hinge device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rudder adjustment device for a ship having a flap rudder angle adjustment function, and more particularly to a rudder adjustment device for a ship capable of variably controlling the angle of a rudder rudder.

In order to improve the efficiency of the rudder for the ship, rudder control system of a ship connected with a rudder blade is used.

However, in the case of flap tack, there are many cases where the steering angle of the diagonal is rarely used during normal operation, and the steering angle of the diagonal is often used in the low speed, especially in the port.

Related prior arts are Korean public room Yongshin public opening No. 20-2013-0000570 'Flap interlocking device and hinge device for marine rudder'.

It is an object of the present invention to provide a rudder adjusting device capable of variably controlling the angle of a flap rudder in a rudder adjusting device.

Another object of the present invention is to provide a rudder control device capable of exhibiting better steering performance at low speeds.

The present invention relates to a rudder trunk, a rudder blade connected to the rudder trunk in an angle-adjustable manner, A flapper rotatably connected to the rudder blade; And an angle adjusting device for adjusting the angle of the flap rattles with respect to the rudder blades.

Wherein the angle adjusting device comprises: a first link which is held in a fixed state in a direction parallel to a center axis of the hull; A slider slidable on the first link; And a second link having one end slidably installed along the central axis of the flap and the other end rotatably connected to the slider.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a rudder adjusting device for a ship having a variable adjusting function of a flap angle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving it will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings.

It should be understood, however, that the present invention is not limited to the embodiments disclosed herein but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a side view showing a rudder adjustment device of a ship according to the present invention.

As shown in the drawing, the rudder adjustment device 100 of the present invention includes a rudder blade 120 rotatably connected to a rudder trunk 110 formed on a hull, And an angle adjusting device 200 for varying the angle of the flap rattles 130 according to the angle of the rudder blades 120 so that the angle of the rattler blades 120 can be variably controlled.

The angle regulating device 200 includes a first link 210 that is fixed to a center axis of the hull passing through a pivot 125 of the rudder blade 120, And a second link 230 connecting the slider 220 and the first link 210. The slider 220 is connected to the first link 210,

The first link remains fixed in a direction parallel to the central axis of the hull.

One end of the second link 230 is connected to the slider 220 so as to be slidable along the central axis (SC in FIG. 2) of the flap 130 and the other end is rotatably supported by the slider rotation shaft 225 .

The present invention is characterized in that the angle of the flap rim 130 can be variably adjusted by adjusting the position of the slider 220 or adjusting the angle of the second link 230 rotatably connected to the slider 220 do.

FIG. 2 is a plan view showing an operating structure of a rudder adjusting device of a ship according to the present invention, and FIGS. 3 and 4 are views showing a change in flap angle according to the movement of a slider of a ship rudder adjusting device according to the present invention.

When the rudder blade 120 has the steering angle A with respect to the center axis SC of the ship, the first link 210, the second link 230, and the slider 220 are interlocked The flap rim 130 also has the flap angle B.

The flap angle B becomes larger as the slider 220 moves away from the pivot 125 of the rudder blade 120 on the first link 210 and conversely the rudder blade 120 And the smaller the closer to the pivot shaft 125 is.

The first embodiment of the present invention is provided with position adjusting means for adjusting the position of the slider 220 relative to the first link 210.

The position adjusting means may move the slider 220 on the first link 210 using a chain and a sprocket or move the slider 220 on the first link 210 using a linear motor.

To increase the flap angle B, the slider 220 is moved on the first link 210 away from the pivot 125 of the rudder blade 120 and the flap angle B as shown in Fig. The slider 220 may be moved on the first link 210 so as to approach the pivot 125 of the rudder blade 120 as shown in FIG.

The position of the slider 220 can be adjusted according to the speed of the ship.

When the slider 220 is positioned at a position close to the rotation axis 125 of the rudder blade 120 so that the flap angle B becomes smaller when the ship is flying at a high speed, B) changes but the flap angle B has a small angle. If the flap angle B is increased during high-speed operation, an excessive load may be applied to the flap rim 130, thereby decreasing durability.

Conversely, if the slider 220 is positioned on the first link 210 at a position relatively far from the pivot 125 of the rudder blade 120 so that the flap angle B becomes larger when the ship is operating at low speed, The flap angle B is greatly changed according to the steering angle of the blade 120, so that the steering performance of the ship can be improved. This is because the load applied to the flap rim 130 is relatively small at the time of low-speed operation, so that even if the flap angle B increases, the durability is not impaired.

The second embodiment of the present invention is provided with angle adjusting means for adjusting the angle of the second link 230 pivotally connected to the slider 220 with respect to the slider. The slider 220 having the angle adjusting means slides on the first link 210 with no force.

The slider 220 is moved on the first link 210 in a direction away from the pivot 125 of the rudder blade 120. On the contrary, when the angle adjusting means operates to increase the flap angle B, The slider 220 moves on the first link 210 in the direction of approaching the pivot 125 of the rudder blade 120 when the means operates to make the flap angle B smaller.

The angle adjusting means may be composed of a drive motor, gears, and the like.

Table 1 below shows the flap angle according to the change of the steering angle according to the relative position of the slider on the silver first link.

Where y is the distance between the pivot 125 of the rudder blade 120 and the pivot 130 of the flap 130 and is the distance between the pivot 125 of the rudder blade 120 and the pivot 135 of the slider It is a street.

Since the length of y is always constant, the length of y is 1, and the length of x is expressed as a relative size to the length of y.

Figure pat00001

As shown in Table 1, when the length of x is small, the flap angle B is slightly larger than the angle A, but when the length of x is large, the flap angle B is larger than the angle A So that the steering performance is improved.

As described above, according to the present invention, the rudder adjusting device of a ship having a variable adjusting function of the flap angle can variably adjust the flap angle of the flap rudder adjusted according to the rudder angle of the rudder blades, And it is possible to exert a better steering performance at a low speed without causing a problem of increasing the capacity of the steering wheel.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, many variations and modifications may be made without departing from the scope of the present invention. It will be understood that they may be selectively combined. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
