1 is a conceptual diagram of a mobile harbor that is an example of a floating body, Figure 2 is a conceptual diagram showing the principle of the balancing device of the floating body according to the present invention, Figures 3 to 8 show embodiments of the present invention to be.

As shown in FIG. 1, the floating body 1, such as a mobile harbor, is capable of loading and unloading cargo 3 at sea. That is, after docking the vessel (not shown) such as a container ship through the docking device 5 at sea, using the loading and unloading device 7 to unload the cargo (3) to the vessel or to load the cargo of the vessel .

At this time, since the loading and unloading work of the cargo 3 is performed at sea, rocking occurs in the floating body 1 during the loading and unloading work of the cargo 3, and the shaking of the cargo 3 Since the loading and unloading operation may be difficult, the float 1 requires a balancing device for maintaining the equilibrium of the float 1.

Here, although the causes of fluctuation of the floating body (1) generated in the sea are various, typically due to blue, algae, or wind, these fluctuation causes may form their own waves. For example, in the case of blue, in the design of general ship equipment, the wave period may be set within about 5 seconds. Of course, such a cycle may be set differently depending on the structure of each ship device and the working environment of the ship device, in the present invention may be set differently depending on the working position of the floating body (1).

As shown in FIG. 2, the masses A and B in accordance with the oscillation period of the floating body, for example, the oscillation period of the moving port (reference numeral 1 of FIG. 1) by blue, algae, or wind having a predetermined period. ) Is rotated in the X direction, but the centrifugal forces FA and FB by the rotation of the masses A and B are adjusted to be equal to each other, the floating body 1 has a moment M due to the masses A and B. (Moment in the direction perpendicular to the XY plane) is generated.

Here, the magnitude of the moment M can be obtained as shown in Equation 1 below.

(m is the mass of each mass, r is the radius of rotation, ω is the rotational angular velocity, L is the distance from the center, and subscripts A and B are the masses)

At this time, the moment (M) also has a constant period in conjunction with the rotation period of the mass (A, B), the direction is changed, the cycle of the moment (M) is the cause of the fluctuation, for example, blue, algae, or wind The oscillation of the floating body can be reduced or eliminated by making the moment M in the direction opposite to that of the floating body in accordance with the oscillation period of the floating body by, for example.

In addition, due to the change in the intensity or periodicity of the cause of fluctuation, or the change in the weight distribution of the floating body due to the internal cause of the floating body, for example, loading or unloading of the cargo (reference number 3 in FIG. 1) in the floating body 1 When there is a change in the weight distribution of the fluid (1), there may occur a case in which the amount or period of generation of such moment (M) needs to be changed, in which case the change of rA, rB, ωA, ωB, LA, or LB Through the generation period and the magnitude of the moment (M) can be changed.

That is, when it is necessary to increase the amount of generation of moment M, rA, rB, ωA, ωB, LA, or part of all of LB is increased or when the amount of generation of moment M is reduced, rA, rB By reducing a part or all of ωA, ωB, LA, or LB, the amount of generation of the necessary moment M can be adjusted.

Here, only some of these variables may be changed, and others may be fixed in advance.

On the other hand, when the equilibrium holding device of the floating body of this principle is provided in order to generate the moment (M) in the opposite direction to the swinging of the floating body, the moment in the direction perpendicular to the XY plane by the rotation of the mass (A, B) Other moments, for example, the moment in the Y direction, etc. may occur, in order to offset this, the balancing device of the floating body may be provided side by side in pairs.

That is, the moving motor assembly 465, which is a reference point of the movement of the rotating body 410, is disposed at either end of the feeding shaft or at the center of the feeding shaft 464 that does not interfere with the pair of eccentric rotating units U, The feed shaft 464 may be rotated.

Here, the one side portion 464a and the other side portion 464b of the feed shaft 464 may be formed opposite to each other in the direction of the screw.

In addition, the moving motor assembly 465 may be configured to rotate one side portion 464a and the other side portion 464b of the feed shaft 464 at the same time. In this case, the moving motor assembly 465 may rotate the one side portion 464a and the other side portion 464b of the feed shaft 464 at the same time to forward or reverse rotation. U may be conveyed closer to each other or farther from each other, thereby adjusting the separation distance L.

Referring to FIG. 11B, any one of the eccentric rotation units U (eg, the eccentric rotation unit disposed on the left side in FIG. 11B) may be fixed by fixing means 490 such as a breaker or a stopper, and the feed shaft 464. ) May not be combined with).

In addition, the other of the eccentric rotation unit (U) (for example, the eccentric rotation unit disposed on the right in Figure 11b) is not a separate temporary fixing means 490, the transfer block 461 and the feed shaft 464 and It can be configured to be linearly movable by the guide rail.

The moving motor assembly 465 may be coupled to rotate the feed shaft 464.

The feed shaft 464 at this time has a screw 464c in a single direction.

When the feed shaft 464 rotates forward or reversely according to the operation of the moving motor assembly 465, the distance that is disposed closer to or farther away from the eccentric rotation unit U is located on the left side. The range of (L) can be adjusted.

As such, the range of the separation distance L may be adjusted by the transfer device 460 shown in FIG. 11A or 11B.

Here, the minimum distance L _min and the maximum distance L _max, which may define the range of the separation distance L, may be obtained as in Equation 2.

(d is the horizontal distance from the moving motor assembly to each rotor, t is the horizontal distance from each rotor to the end of the frame, and e is the length of the joint)

That is, in the case of the distance adjusting first model, the minimum distance L _min which can be adjusted cannot be reduced to 0.5 or less of the maximum distance L _max , no matter how small.

However, since the driving device 450 is not at a position between the rotors 410 and is disposed outward of the one rotor 410, the distance L between the rotors 410 is relatively relatively increased. As compared with the first to fourth embodiments, it can be adjusted within a relatively wide range.

12 is a plan view of a distance control second model of the present invention.

Referring to FIG. 12, the second distance control model may further include a third shaft 530 serving as a main shaft for transmitting power to each eccentric rotation unit U.

The third shaft 530 is spaced apart from the eccentric rotation unit U, is installed in parallel with the feed shaft of the drive shaft 420 or the transfer device 460, the power of the drive device 450 (including the drive motor and the reducer) Through the power transmission mechanism 540, such as a pulley (gear) or gear (gear) can play a role to be transmitted to the drive shaft 420 which is the driven shaft.

The third shaft 530 may be rotatably supported by bearings 550 provided at both ends of the third shaft 530. The bearing 550 may be installed to be supported by the installation surface on which the transfer device 460 is installed.

The power transmission mechanism 540 includes a driving part 541 (for example, a driving pulley or a gear) slidably inserted and coupled to the third shaft 530, and a driven part 542 fixed or coupled to the driving shaft 420 ( For example, a driven pulley or gear) and an interlocking portion 543 (for example, a belt or a gear) coupled between the main body 541 and the driven part 542 to transmit power.

At this time, the third shaft 530 and the main body 541 is coupled through a sliding coupling having a spline cross-sectional shape, so that the power or torque can be transmitted while adjusting the separation distance L between the rotating bodies 410. Do it.

In the shaft system according to the second distance control model, the driving device 450 may be connected to the outside of any one of the third shaft 530 and the driving shaft 420 of the eccentric rotation unit (U).

The separation distance L may be adjusted by the transfer device 460 including the transfer block, the guide rail, the feed shaft, and the like as described in the above-described distance adjustment second model.

In this case, since the moving part 541 installed on the third shaft 450 must move together with the eccentric rotation unit U, the moving fork 544 attached to the frame of the eccentric rotation unit U is used. The main driving part 541 on the three axis 530 side can be moved. In this case, the moving fork 544 may include a support connected to the frame of the eccentric rotation unit U, and a U-shaped guide part formed at the end of the support and slidingly contacting the surface of the main drive 541.

In this case, the minimum distance L _min and the maximum distance L _max, which may limit the range of the separation distance L that may be adjusted by the transfer device 460, may be obtained as in Equation 3 below.

(t is the horizontal distance from each rotor to the end of the frame, s is the length between the bearings of the third axis, a is the horizontal distance from each rotor to the bearings of the third axis, b is the main or driven part from the bearing of the third axis) Means the interval between

That is, the smaller the t, the smaller the minimum moment M _min can be. Of course, M _max can be made larger by increasing s.

In practice, since the vibration of the floating body may be large or almost absent, it is ideal that the stabilization moment should be large or small. Therefore, it can be said that the distance adjusting second model is superior to the distance adjusting first model.

FIG. 13A is a plan view of a third model of distance adjustment of the present invention, and FIG. 13B is a front view of the third model of distance adjustment shown in FIG. 13A.

Referring to FIG. 13A or FIG. 13B, referring to the third model of distance control, two eccentric rotation units U are spaced apart so that each driving shaft 420 of the eccentric rotation unit U is arranged in parallel with a separation distance. There may be.

The fourth shaft 600 and the fifth shaft 610 may be arranged in a space between the eccentric rotation unit U in parallel with the driving shaft 420.

The distance between the eccentric rotation unit (U) may also be configured to be adjusted by the transfer device 460 including a transfer block, a guide rail, a feed shaft, and the like as described in the above-described distance adjusting second model.

In addition, both ends of each of the fourth shaft 600 and the fifth shaft 610 arranged in parallel are coupled to a bearing block installed in the space between the eccentric rotation unit (U) to avoid interference, each bearing block is a block Connected to the guide device (700, 710, 720, 730), the fourth axis 600 and fifth axis 610 and each bearing block is configured to be guided in the ascending or descending direction while maintaining the horizontal It is.

Each drive shaft 420 and the fourth shaft 600 or the fifth shaft 610 are connected to the pulleys 601 and 602 and the belt 603, respectively, and the rotation direction of the rotating body 420 can be reversed. The phase angle can also be 180 degrees.

To this end, the fourth shaft 600 and the fifth shaft 610 may further include gears 604 and 605 to reverse the direction of rotation.

Like the other models described above, the driving device 450 of the third distance-controlling model may be installed on any one of the fourth shaft 600, the driving shaft 420, and the fifth shaft 610, and one driving motor. Can be driven.

The rotating body 410 used in the third distance-controlling model may have a mass body 411 in the shape of a plate so that the two may rotate closest to each other without colliding with each other, and the position of the mass body 411 may be offset (f).

In this case, in theory, L _min can be 2r.

The distance of the two rotating bodies 410 can also be adjusted by a feeder 460 such as a lead screw as in the other models, and can be passively adjusted by vertical movement of the fourth and fourth shafts 600 and 610. have.

For example, when the two eccentric rotation units U are conveyed away from each other by the conveying device 460, the fourth shaft 600 and the fifth shaft 610 are driven by the predetermined belt 603 length and its tension. And each bearing block may be passively raised along the block guide device (700, 710, 720, 730).

In addition, when the two eccentric rotation unit (U) is conveyed toward each other by the conveying device 460, also due to the gravity of the belt 603 length, tension, axis or bearing block, the fourth shaft ( 600 and the fifth shaft 610 and each bearing block may be passively lowered along the block guide device (700, 710, 720, 730).

The fourth model, not shown, applies the above-described models, but instead of a single driving device, a separate individual driving motor is mounted on each of the eccentric rotation units so that the drive shaft of the eccentric rotation unit can be rotated. Can be.

At this time, each of the eccentric rotation unit can be adjusted to the mutual distance by the transfer device.

However, the fourth model has a simple structure because the drive shaft is not connected between the eccentric rotation units, but a large torque may be required because the individual drive motors must drive the eccentric rotating bodies. Applicable to

In the following, application apparatuses for applying to a floating body using various types of model units described above will be described.

Fig. 14 is a plan view of a first applicator having a float balancing device in pairs, and Fig. 15 is a plan view of a second applicator for simultaneously controlling the roll and the pitch of the float.

Referring to FIG. 14, since the first application device 800 does not always have a moment in a direction perpendicular to the components connecting the two eccentric rotation units U, the first application device 800 may be selected from the above-described distance adjusting first to fourth models. Distance adjustment models 801 and 802 can be installed in pairs to precisely match the direction of moment action.

For example, the pair of distance adjustment models 801 and 802 in the first application device 800 are spaced apart from each other by a predetermined distance, and at this time, the rotation of the rotating body between the models 801 and 802 is reversed. Direction, it is possible to generate a relatively large area of moment and facilitate the balancing control of the floating body.

Referring to FIG. 15, the second application device 810 may include two pairs of distance control models 811, 812, 813, and 814 in a paired basic arrangement as described with reference to FIG. 14. Rolls and pitching can be controlled together by placing them at right angles to correspond to the pitching direction.

In addition, since the minimum stabilization moment may be relatively large other than the distance adjusting second model described above with reference to FIG. 12, when there is little vibration of the floating body, it may be difficult to reduce the vibration. In addition, it can be installed with a small distance control model or a small application device of relatively small capacity, so that it can be applied to generate a smaller moment.
