Hereinafter, other objects and features of the present invention in addition to the above objects will be clearly revealed through the description of the embodiments with reference to the accompanying drawings.

Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. Terms such as those defined in a commonly used dictionary should be interpreted as having a meaning consistent with the meaning in the context of the related technology, and should not be interpreted as an ideal or excessively formal meaning unless explicitly defined in this application. Does not.

Hereinafter, with reference to the accompanying drawings to describe a preferred embodiment of the posture stabilization device for a ship according to the present invention.

The ship's attitude stabilizing device 1 according to the present invention includes a movable plate 10, a rotating means 20, a lifting means 30, and a blocking film 40.

Meanwhile, in the following description, when the ship is inclined to one side in the process of rolling in the left and right direction, moving upward in the inclining process is referred to as rising, and moving downward is referred to as descending.

And, the rising and lowering of the movable plate is called ascending when the movable plate disposed on the upwardly inclined side moves upward while the ship is rolling in the left and right direction, and the movable plate disposed on the downwardly inclined side moves downward. Moving is called descent.

The movable plate 10 extends in the longitudinal direction and is formed in the form of a flat plate having a predetermined width, and a pair of the movable plate 10 is disposed in a direction symmetrical to each other, and the lower ends are disposed so as to contact each other.

The overall length and width of the movable plate 10 are selectable according to the size of the ship, and there is no particular limitation.

In addition, the movable plate 10 shown in the drawing is generally in the form of a square plate, but a triangle narrowing toward the bottom, a triangle or semicircular shape narrowing toward the top, or a plurality of ribs are arranged radially and gathered toward the center. It can be changed into various shapes such as the shape of an umbrella that opens outward.

Here, the movable plate 10 is disposed so that the lower ends are in contact with each other, but is rotatably coupled by a rotating means 20 to be described later, so that the pair of movable plates 10 can be folded when not in use, thereby minimizing the space required for storage. I can.

On the other hand, the movable plate 10 is further formed with a support plate 12 bent horizontally in opposite directions to each other at the top, the support plate 12 is moved up and down while the movable plate 10 is disposed underwater. When the movable plate is not inclined, it is supported to move vertically up and down.

The movable plate 10 has a storage space 11 formed therebetween while a pair of the movable plates 10 are separated from each other, and seawater is stored in the storage space 11 to restrict the ship from moving upward by waves.

That is, when the ship is rolled left and right by waves, the movable plate 10 also moves upwards or downwards at the same time, rotates in the direction of spreading or gathering, and the resistance force generated by the weight of seawater stored in the storage space 11 This is to limit the ship's movement upward. This is because the resistance force generated through the sum of the weight of seawater stored in the storage space 11 and the resistance force generated by the area of the movable plate 10 limits the rise of the ship to stabilize the ship's attitude and minimize the rolling phenomenon. do.

Looking at this with reference to FIG. 3, the movable plate 10 restricts the movement of the ship upward while the ship is rolled left and right in the process of being rolled left and right by the waves. It can be maintained.

At this time, the ship's posture stabilization device according to the present invention is disposed on the left and right sides of the ship as shown in FIG. 3 so that the ship is horizontal while moving in opposite directions when rolling.

Here, when the movable plate 10 is put into the water after stopping in the operating state, the movable plate 10 waits in an open state in a direction away from each other and limits the movement of the ship upward by the waves.

In addition, since the storage space 11 formed between the movable plates 10 is formed in a state where both sides are closed by a blocking film 40 to be described later, seawater of a certain capacity is discharged while the movable plate 10 is open to both sides. Even if the force to lift the ship is generated by maintaining the stored state at all times, it is possible to form resistance against ascent by the weight of seawater.

The rotating means 20 is coupled to the lower end of the pair of movable plates 10 in contact with each other to rotate the upper end of the movable plate 10 in a direction close to or away from each other, wherein the rotating means 20 is a movable plate ( 10) It is desirable to be configured so as to limit the angle at which they are separated from each other.

That is, when the movable plate 10 is placed underwater, it rotates in a direction away from each other when moving upward, that is, the movable plate 10 is rotated and at the same time, it is movable by preventing it from rotating beyond a predetermined angle. It prevents the plate from being overturned by the weight of seawater in the process of moving upward.

To this end, the rotation means 20 including the angle limiting means are used in various doors and various industrial fields, and a detailed description of the internal structure will be omitted.

The elevating means 30 is for elevating the movable plate 10 from underwater to a ship, and a elevating wire 32 for binding a plurality of ropes 31 and a plurality of ropes 31 into one, It includes a take-up roller 33 to which the lifting wire 32 is wound, and a driving motor 34 for rotating the take-up roller 33.

One end of the rope 31 is coupled to the movable plate 10, and preferably a pair is coupled to each other in a state that is spaced apart in the longitudinal direction, but is symmetrical with respect to the center point in the longitudinal direction of the movable plate 10 Is coupled to the position.

As for the rope 31 used herein, various materials may be used, and there is no particular limitation on the material.

On the other hand, the rope 31 has both ends fixed to each movable plate 10 and the center may be formed in a form of binding with the lifting wire 32 to be described later, through which the movable plate 10 is separated from each other angle. Can be limited.

That is, when both ends of the rope 31 are coupled to each movable plate 10, the movable plate 10 is rotated only by the length of the rope 31, so that the rotation angle of the movable plate can be adjusted to the length of the rope. will be.

On the other hand, the rope 31 is disposed below the center line in the width direction of the movable plate 10, through which the movable plate 10 pulled upward by the rope 31 is vertically maintained while maintaining an open state. Go to.

That is, since the movable plate 10 generates resistance at the same time as the ship rises in a mutually open state, the rolling phenomenon of the ship can be minimized (see FIGS. 3 and 4).

The lifting wire 32 is a metal wire having high durability to support the weight of seawater stored in the storage space 11 of the movable plate 10 as the other ends of the plurality of ropes 31 are each bound together. ) Is preferably used, and more preferably, a metallic wire and a cloth material surrounding it in several layers are included in order to minimize corrosion due to salt.

The take-up roller 33 is one end of the lifting wire 32 is fixed to wind or unwind the lifting wire 32 according to rotation, and a known take-up roller is used, but is disposed on the deck or side of the ship.

Further, the driving motor 34 rotates the take-up roller 33 while being driven by the applied power and signal.

Such an elevating means 30 is used to remove the movable plate 10 from underwater in order to store the movable plate 10 on the deck of the ship during the operation of the ship.

The blocking film 40 is to close openings formed at both ends of the pair of movable plates 10 in the longitudinal direction, and both ends are fixed to the pair of movable plates 10 and folded according to the position of the pair of movable plates. The storage space 11 formed between the pair of movable plates 10 is closed or configured to be unfolded.

That is, the blocking film 40 forms a storage space 11 in which seawater is stored between the pair of movable plates 10, and is unfolded when the movable plate 10 is opened and folded when it is close. It is made of a material or a soft synthetic resin material.

In addition, the blocking film 40 can additionally obtain an effect of preventing the movable plate 10 from spreading beyond a predetermined angle. The rotation of the movable plate 10 is prevented when the blocking film 40 is fully extended. By limiting, it is possible to prevent the movable plate 10 from being overturned.

As described above, the blocking film 40 closes both sides of the storage space 11 formed between the pair of movable plates 10 to maintain a state where seawater is always stored in the storage space 11, and stored seawater It minimizes the rolling phenomenon by forming resistance against the rise of the ship through the weight of

In addition, in a state in which the blocking film 40 is not provided, when the seawater moves by the ocean current, the movable plate 10 deviates from the horizontal state, so that the area forming the resistance force decreases, thereby reducing the resistance force.

However, in the present invention, even if the movable plate 10 is inclined by an ocean current, the amount of seawater stored in the storage space 11 by the blocking film 40 is the same, so that resistance is not lost.

In the present invention made as described above, when the ship moves up and down by waves while the ship is stationary on the water surface, seawater is stored in the storage space 11 formed by the movable plate 10 and the blocking film 40. It is possible to stably maintain the attitude of the ship by limiting the movement of the ship upward through the weight of the stored seawater.

In addition, when the movable plate 10 moves up and down and moves away from each other or close to each other during a rotational operation, it is possible to maintain a horizontal level through the support plate 12 formed on the movable plate 10, thereby increasing the reliability of the operation.

Meanwhile, the movable plate 10 is preferably moved up and down in an open state, and this will be described in more detail as follows.

When the movable plate 10 is placed underwater, it maintains a mutually open state, so that when the ship rises, the resistance force is generated by interlocking with each other to prevent a rolling phenomenon due to the rise of the ship.

That is, the storage space 11 formed by the movable plate 10 and the blocking film 40 is in a state where seawater is always stored, so even if the movable plate 10 is pulled upward by the rising of the ship, the weight of the seawater Resistant force is generated to suppress this.

Therefore, in the present invention, it is preferable to move the movable plate 10 up and down while maintaining the mutually open state, and in particular, when the ship is repeatedly raised and lowered left and right due to the rolling phenomenon, the movable plate at a lowering position ( 10) is prepared for the next ascending operation after the descending speed is made quickly, and the movable plate 10 in the elevated position must maintain resistance against ascending to minimize the shaking of the ship due to the rolling phenomenon.

Here, the auxiliary movable body 50 shown in FIG. 5 is further provided as a means for further minimizing the shaking of the vessel together with the resistance of the movable plate 10.

The auxiliary movable body 50 is provided in the movable plate 10, wherein the movable plate 10 is provided with an entrance 13 formed through the longitudinal direction, and the entrance 13 is the storage space 11 ) Is formed through to communicate with the outside.

In addition, the auxiliary movable body 50 includes an opening/closing plate 51 for opening and closing the entrance 13, and a hinge 52 for coupling the opening/closing plate 51 to the movable plate 10 so as to be rotatable. .

At this time, the entrance 13 is shown that one is formed on the movable plate 10 in the drawing, but as another embodiment, a plurality of the movable plates 10 may be formed at regular intervals. It can also be formed in position.

The opening/closing plate 51 opens or closes the entrance 13, and has a relatively large area compared to the entrance 13 to close the entrance 13 and is formed in a flat plate shape.

In addition, the hinge 52 is coupled to one end of the opening and closing plate 51 to the movable plate 10, but the opening and closing plate 51 is rotatably coupled.

In the auxiliary movable body 50 made as described above, the opening and closing plate 51 closes the entrance 13 in the process of moving upward while the movable plates 10 are spreading each other, and conversely, while the movable plates 10 are close to each other. When moving downward, open the doorway (13).

Through this, the resistance force of seawater generated when the movable plate 10 moves downward is dispersed through the entrance 13 so that the movable plate 10 can be quickly moved downward.

That is, in the process of moving the movable plate 10 downward, a resistance force that is restricted by seawater is generated. By opening the doorway 13, the seawater that is the cause of the resistance force is moved so that the movable plate 10 is folded to each other. It rotates in the direction and at the same time makes it possible to quickly move downwards.

Accordingly, there is an advantage in that the movement of the movable plate against the waves can be made quickly, thereby enhancing the effect of stabilizing the attitude of the ship.

In addition, when the height of the wave is not high, the auxiliary movable body 50 allows the movable plate 10 to descend quickly while descending while the movable plate 10 is open to both sides.

This is to increase the descent speed of the movable plate 10 by dispersing the resistance force by allowing external seawater to move toward the storage space 11 as the opening/closing plate 51 is opened when descending (see FIG. 8).

In addition, in the present invention, as shown in FIG. 6, a movable plate tilting module 60 is further provided for tilting to one side and raising the movable plate 10 in the process of receiving the ship.

That is, the movable plate tilting module 60 must move the movable plate 10 away from the water and move to the ship while the ship is operating again in a stopped state.

At this time, when the movable plate 10 is raised in a state that is open to both sides, a stronger force is required for the ascent, and there is a problem in that the drive motor 34 of the lifting means 30 must be provided in a large size for this purpose.

Therefore, by solving this problem and using the small drive motor 34, the movable plate 10 is inclined to one side and separated from the water in order to reduce the volume occupied by the drive motor 34 and eliminate overload.

To this end, the movable plate tilting module 60 includes a pull wire 61 having one end coupled to one side in the length direction of the movable plate 10, and a driving part 62 for raising the pull wire 61. .

Here, the driving unit 62 may include a motor operated by an applied power and a signal, and a winding roller configured to wind or unwind the pull wire 61 while being coupled to the motor to rotate.

It is necessary to raise the movable plate 10 by first raising the movable plate 10 to one side through the movable plate tilting module 60 and then tilting the movable plate 10 from the water through the lifting means 30. It has the effect of shortening the time and allowing the movable plate 10 to rise even when a relatively small drive motor is used.

And, in the present invention, there is further provided a resistance blade 70 protruding in the horizontal direction from the lower end of the movable plate 10 in contact with the movable plate 10 as shown in Figure 7, the resistance blade 70 is a movable plate 10 In the process of ascending and descending, it is possible to move vertically upwards or downwards.

Here, the resistance blade 70 is made of a cloth material having elastic force, and is gently bent downward when the movable plate 10 rises to form a resistance force to suppress the rise of the movable plate 10, and has a predetermined length and It is formed to have a width to prevent the movable plate 10 from tilting to one side when rising or falling.

In addition, a plurality of the resistance blades 70 may be disposed at regular intervals, and when viewed from the upper side, the pair of movable plates 10 may be configured to protrude horizontally at mutually alternating (交互) positions. I can.

On the other hand, it is more preferable that the resistance blade 70 is rotatably coupled to one side of the movable plate 10 through a hinge so that it is unfolded when the movable plate is raised and folded when the movable plate is lowered.

And it is preferable that the resistance blade is made of the same metal material as the movable plate 10 to prevent corrosion, and at this time, as shown in FIG. It can be placed to increase the resistance.

As described above, in the present invention, specific matters such as specific components, etc., and limited embodiments and drawings have been described, but this is provided only to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , If a person of ordinary skill in the field to which the present invention belongs, various modifications and variations are possible from these descriptions.
