The present invention may, however, 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, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

FIG. 2 is a cross-sectional view of a support according to an embodiment of the present invention, and FIG. 3 is a cross-sectional view of a vessel supporting apparatus according to an embodiment of the present invention, Fig.

1 to 3, the vessel supporting apparatus 10 includes a support unit 100, a buoyancy control unit 200, and a fluid transfer unit 300.

The support part 100 has a closed inner space for receiving the fluid and is in close contact with the lower surface of the ship to support the ship. For example, the support 100 may have the shape of an airbag. The support portion 100 can provide a pushing force to the ship in close contact with the lower surface of the ship. Here, the force pushing the ship up can be buoyancy.

In order to provide buoyancy, an interior space for accommodating the gas may be provided inside the support part 100. As the gas is received in the internal accommodation space, buoyancy is generated in the support portion 100, and the generated buoyancy can be provided to the ship.

The support portion 100 may have a shape corresponding to the lower surface of the ship in order to provide buoyancy to the entire lower surface of the ship. Also, a separation preventing portion 110 may be provided along the edge of the supporting portion 100 to prevent the supporting portion 100 from being separated from the lower side of the ship.

As shown in FIGS. 1 and 2, the separation preventing portion 110 may be provided along the edge of the support portion 100. The separation preventing portion 110 may protrude from other portions of the support portion 100 and may cover the lower side surface of the ship. The separation preventing portion 110 surrounds the lower side surface of the ship so that the support portion 100 can be prevented from being separated from the lower portion of the ship.

Also, according to some embodiments of the present invention, the support 100 may be secured to the vessel by separate securing means (not shown). For example, a magnetic force body may be provided on the upper surface of the support portion 100. Accordingly, the support portion 100 and the ship can be magnetically coupled to prevent the support portion 100 from being detached from the lower portion of the ship.

The engagement and disengagement between the support portion 100 and the ship can be easily performed regardless of the presence or absence of the fixing means. For example, when the gas is completely removed or the liquid is filled in the internal space of the support part 100, the buoyancy is removed, so that the connection between the support part 100 and the ship can be released naturally.

As described above, in the present invention, a ship supported by the support portion 100 may be a ship under construction. Accordingly, since the coupling and disengagement between the support part 100 and the ship are easily performed, the ship supporting device 10 can be easily applied to various ships to adjust the draft of the ship.

The buoyancy control unit 200 controls the buoyancy of the support unit 100 by supplying liquid or gas to the support unit 100 or extracting the liquid or gas contained in the support unit 100 according to a change in the draft of the ship.

As described above, in the present invention, the object supported by the support portion 100 may be a ship being dried. The construction of the ship may proceed after the launch. In other words, the ship can be added to the ship in a state where the ship is docked on the sidewalk.

A fender may be installed on the wall to prevent collision between the ship and the wall. The fender contacts the side of the vessel and maintains the distance between the vessel and the vessel wall.

On the other hand, as the ship is dried, structures and the like are added and the weight of the ship may increase. As the weight of the ship increases, the draft increases as the ship sinks to a certain depth. Alternatively, the structure may be installed on the ship and removed for the purpose of drying the ship. For example, a small crane can be removed while working on the ship's deck. When a structure such as a crane is removed, the weight of the ship is reduced. When the weight of the ship is reduced, the ship floats to a certain depth and the draft is reduced.

Thus, during the drying of the ship, a change in weight is accompanied by the vertical movement of the ship at sea level. If the ship is moved vertically, the surface of the ship may be damaged due to friction with the fender.

In order to prevent damage to the surface of the ship due to friction with the fender, it is desirable to limit the vertical movement of the ship. The buoyancy control unit 200 according to the embodiment of the present invention can limit the vertical movement of the ship even if the weight of the ship changes. For this purpose, the buoyancy control unit 200 may control the buoyancy of the support unit 100. That is, the buoyancy control unit 200 may increase the buoyancy of the support unit 100 when the weight of the ship is increased and decrease the buoyancy of the support unit 100 when the weight of the ship is decreased. The buoyancy control of the buoyancy control unit 200 allows the vertical movement of the ship to be reduced. A detailed description of the configuration of the buoyancy control unit 200 will be given later with reference to FIG.

The fluid transferring part 300 serves to transfer the fluid between the support part 100 and the buoyancy control part 200. The fluid transferring part 300 includes a gas transferring part 310 for transferring the gas and a liquid transferring part 320 for transferring the liquid.

The gas transfer unit 310 transfers the gas from the support unit 100 to the buoyancy control unit 200 or transfers the gas from the buoyancy control unit 200 to the support unit 100. Likewise, the liquid transfer unit 320 transfers liquid from the support unit 100 to the buoyancy control unit 200 or transfers the liquid from the buoyancy control unit 200 to the support unit 100.

The gas transferring part 310 and the liquid transferring part 320 may have the shape of a tube. That is, the gas can move between the support part 100 and the buoyancy control part 200 through one pipe, and the liquid moves between the support part 100 and the buoyancy control part 200 through one pipe.

According to some embodiments of the present invention, the gas transfer unit 310 may include a tube for transferring the gas from the supporter 100 to the buoyancy controller 200, and a tube for transferring the gas from the buoyancy controller 200 to the supporter 100 May be provided. Likewise, the liquid transfer unit 320 may include a pipe for transferring the liquid from the support unit 100 to the buoyancy control unit 200, and a separate pipe for transferring the liquid from the buoyancy control unit 200 to the support unit 100. Hereinafter, the gas transfer unit 310 and the liquid transfer unit 320 are embodied as one pipe.

The fluid may be supplied to the support portion 100 through the fluid transfer portion 300 or may be extracted from the support portion 100. A fluid inlet 120 may be provided in the support 100 to receive or extract the fluid. The fluid transfer part 300 can enter the inner space of the support part 100 through the fluid inlet 120. [ The shape of the holes provided in the fluid inlet 120 may be the same as the cross-section of the fluid delivery portion 300. Accordingly, the fluid contained in the support portion 100 can be prevented from flowing out through the fluid inlet 120, not the fluid delivery portion 300.

When the fluid is supplied to the support portion 100 or the fluid is extracted from the support portion 100, the buoyancy change in the portion of the support portion 100 where the fluid inlet 120 is provided in the entire region of the support portion 100, It may be larger than the buoyancy change. That is, since the fluid is supplied or extracted through the fluid inlet / outlet 120, the buoyancy change at the relevant portion progresses faster than the buoyancy change at the other portion, so that the difference in buoyancy between the different portions of the support 100 It can happen.

Uneven force can be applied to the ship when the buoyancy difference occurs in the support portion (100). For example, a large buoyancy force may be applied to the fore part and a small buoyancy force may be applied to the fore part.

The fluid inlet 120 may be located at the center of the lower surface of the support 100 to mitigate unbalanced forces on the ship. The fluid transfer part 300 is connected to the fluid inlet 120 and the fluid can be supplied or extracted through the central part of the support part 100. The increased buoyancy spreads outward from the center of the support portion 100 or the reduced buoyancy spreads outward from the center of the support portion 100 so that the ship can be provided with buoyancy in a balanced state.

On the other hand, the portion of the bottom surface of the ship where the center of gravity of the ship is applied may not be the center of the bottom surface. For example, the position of the center of gravity of the ship may vary depending on the position of the structure mounted on the ship.

Accordingly, according to some embodiments of the present invention, the support 100 may have a plurality of fluid ports. Thus, among the plurality of fluid outlets, the fluid transfer unit 300 is connected to the fluid outlets corresponding to the center of gravity of the ship, so that the fluid can be supplied or extracted. The user may allow the fluid to be supplied or extracted through the appropriate fluid inlet in consideration of the center of gravity of the vessel. This makes it possible to provide buoyancy to the ship in a state in which the balance of the ship is maintained.

As described above, the fluid transfer unit 300 may transfer a gas or a liquid, and the fluid transfer unit 300 may include a gas transfer unit 310 and a liquid transfer unit 320. Here, the gas transfer unit 310 is used to perform supply and extraction of gas, and the liquid transfer unit 320 can be used to perform supply and extraction of liquid.

Both the gas and the liquid can be accommodated in the interior space of the support 100. It is preferable to distinguish the gas and the liquid from each other and supply them to the internal accommodation space or to extract them from the internal accommodation space.

The liquid can be accommodated in the lower space of the inner accommodating space. Even if the end of the gas transferring part 310 is included in the lower space of the inner accommodating space in this state, there is no problem in supplying the gas. The supplied gas rises through the liquid and reaches the upper space of the inner accommodating space of the supporter 100. However, in order to extract the gas in the internal accommodation space, the end of the gas transfer unit 310 must be located in the upper space.

Further, the gas can be accommodated in the upper space of the inner accommodating space. In this state, even if the end of the liquid transfer part 320 is included in the upper space of the internal accommodating space, there is no problem in supplying liquid. The supplied liquid descends in the upper space and reaches the lower space of the inner accommodating space of the supporter 100. However, in order to extract the liquid in the inner accommodation space, the end of the liquid transfer part 320 must be located in the lower space.

The end of the liquid transfer part 320 connected to the support part 100 is disposed adjacent to the lower surface of the internal space of the support part 100 and the end of the gas transfer part 310 connected to the support part 100 is connected to the support part 100 The inner surface of the inner receiving space.

FIG. 3 is a cross-sectional view of the supporting part 100, showing the end of the fluid transferring part 300 provided in the internal space of the supporting part 100. As shown in FIG.

The distal end of the liquid transfer section 320 may be disposed adjacent to the lower surface of the support section 100 and the distal end of the gas transfer section 310 may be disposed adjacent to the upper surface of the support section 100. [ Since the ends of the liquid transfer part 320 are disposed adjacent to the lower surface of the support part 100, extraction of gas can be prevented in extracting the liquid. Further, since the distal end of the gas transferring part 310 is arranged adjacent to the upper surface of the supporting part 100, extraction of liquid can be prevented in extracting the gas.

According to some embodiments of the present invention, the liquid transfer unit 320 is divided into a liquid supply unit (not shown) for supplying liquid and a liquid extracting unit (not shown) for liquid extraction. (Not shown) for supplying the gas and a gas extracting unit (not shown) for extracting the gas.

In this case, the ends of the liquid supply portion and the gas supply portion can be freely determined in the internal accommodation space of the support portion 100, and only the ends of the liquid extraction portion and the gas extraction portion can be limited to specific positions. The end of the liquid extracting portion is disposed adjacent to the lower surface of the retainment chamber and the end of the gas extraction portion can be disposed adjacent to the upper surface of the internal accommodation space.

4 is a view illustrating a buoyancy control unit according to an embodiment of the present invention.

4, the buoyancy control unit 200 includes a first valve 211, a second valve 212, a valve control unit 220, a pump unit, a draft measuring unit 240, a gas tank 250, (260) and a drain portion (270).

The draft measuring unit 240 measures the change in the draft of the ship. The draft measuring unit 240 controls the valve control unit 220 and the pump unit based on the measured result.

The valve control unit 220 controls the first valve 211 connected to the gas transfer unit 310 or controls the second valve 212 connected to the liquid transfer unit 320 under the control of the draft measuring unit 240 . The valve control unit 220 opens the valves 211 and 212 and the valve control unit 220 closes the valves 211 and 212 when the fluid is not transferred.

As the first valve 211 is opened, gas transfer is performed through the gas transfer unit 310 and liquid transfer can be performed through the liquid transfer unit 320 as the second valve 212 is opened.

The pump unit may include a first pump 231 and a second pump 232. The pump unit serves to supply liquid or gas to the supporting unit 100 or to extract the liquid or gas contained in the supporting unit 100 under the control of the draft measuring unit 240.

The gas can be supplied to the supporting part 100 or the gas of the supporting part 100 can be extracted as the first pump 231 operates with the first valve 211 opened. Likewise, when the second pump 232 is operated in a state where the second valve 212 is open, the liquid can be supplied to the support 100 or the liquid of the support 100 can be extracted.

When the draft of the ship is increased, the pump unit can provide the power for supplying the gas to the support unit 100 and the power for extracting the liquid contained in the support unit 100. That is, the first pump 231 generates a force to move the gas from the gas tank 250 toward the gas transfer unit 310, and the second pump 232 moves from the liquid transfer unit 320 to the drainage unit 270 It is possible to generate a force for causing the liquid to move.

Further, when the draft of the ship is reduced, the pump section can provide power for supplying the liquid to the support section 100 and for extracting the gas contained in the support section 100. That is, the first pump 231 generates a force to move the gas toward the gas tank 250 from the gas transfer unit 310, and the second pump 232 moves from the water supply unit 260 to the liquid transfer unit 320 It is possible to generate a force for causing the liquid to move.

As the gas is supplied to the supporting part 100 and the liquid is extracted from the supporting part 100, the buoyancy of the supporting part 100 increases. As the liquid is supplied to the supporting part 100 and the gas is extracted from the supporting part 100, buoyancy of the supporting part 100 is decreased. As the buoyancy of the support portion 100 is adjusted, the variation of the draft of the ship supported by the support portion 100 can be mitigated.

The gas tank 250 serves to store the gas. The gas may be air or helium, but is not limited thereto. The gas stored in the gas tank 250 may be supplied to the support 100 and the gas extracted from the support 100 may be stored in the gas tank 250. A separate gas may be injected into the gas tank 250. If the internal pressure of the gas tank 250 is excessively high, a part of the gas contained in the gas tank 250 may be discharged to the outside have.

The water supply section 260 provides a path for transferring the liquid to the second pump 232 and the drain section 270 can provide a path for discharging the liquid transferred from the second pump 232. For example, the water supply 260 may have the form of a tube connected to the seawater around the seawall. That is, the end of the water supply unit 260 provided with the inflow port through which the liquid flows may be located below the sea level. Accordingly, as the second pump 232 operates, the seawater is introduced through the water supply unit 260, and the introduced seawater can be supplied to the support unit 100 through the liquid transfer unit 320.

On the other hand, the liquid flowing through the water supply unit 260 is not limited to seawater around the wall. For example, a separate liquid tank (not shown) for containing the liquid may be provided. In this case, the liquid contained in the liquid tank may be introduced into the support portion 100 through the water supply portion 260, and the liquid extracted from the support portion 100 may be transferred to the liquid tank to be received.

5 and 6 illustrate fluid delivery according to an embodiment of the present invention.

5, the gas contained in the gas tank 250 is discharged through the gas transfer unit 310, and the liquid introduced through the liquid transfer unit 320 may be discharged through the drain unit 270.

The valve control unit 220 may open the first valve 211 and the second valve 212 when it is determined that the draft of the ship has increased according to the measurement result by the draft measuring unit 240. [ The first pump 231 generates a force directed toward the gas transferring part 310 from the gas tank 250 and the second pump 232 generates a force directed toward the drainage part 270 from the liquid transferring part 320 .

Accordingly, a flow of the gas moving from the buoyancy control unit 200 toward the support unit 100 and a flow of the liquid moving from the support unit 100 toward the buoyancy control unit 200 are generated.

As the gas is supplied and the liquid is removed, buoyancy of the support part 100 increases and buoyancy of the support part 100 increases. Thus, even if the weight of the ship increases, the ship is supported by a larger buoyancy, so that the variation of the draft of the ship can be mitigated.

6, the gas introduced through the gas transfer unit 310 is transferred to the gas tank 250, and the liquid introduced through the water supply unit 260 may be discharged through the liquid transfer unit 320.

The valve control unit 220 may open the first valve 211 and the second valve 212 when it is determined that the draft of the ship has decreased according to the measurement result by the draft measuring unit 240. [ The first pump 231 generates a force directed toward the gas tank 250 from the gas transfer unit 310 and the second pump 232 generates a force directed toward the liquid transfer unit 320 from the water supply unit 260 .

Accordingly, the flow of the gas moving from the support portion 100 to the buoyancy control portion 200 and the flow of the liquid moving toward the support portion 100 from the buoyancy control portion 200 are generated.

As the liquid is supplied and the gas is removed, the buoyancy of the support 100 is reduced and the buoyancy of the support 100 is reduced. Thus, even if the weight of the ship is reduced, the ship is supported with a smaller buoyancy, so that the change of the draft of the ship can be mitigated.

7 is a view showing a ship supporting apparatus according to an embodiment of the present invention supporting a ship.

Referring to FIG. 7, the ship 20 can be supported by the support 100. The support portion 100 can support the ship 20 by being in close contact with the lower surface of the ship 20 in a state of being immersed in seawater.

A fender 40 may be provided between the ship 20 and the wall 30. The distance between the ship 20 and the seam 30 can be maintained by the fender 40.

7 shows that the buoyancy control unit 200 connected to the fluid conveyance unit 300 is provided on the septal wall 30, but the buoyancy control unit 200 is not limited in its position. For example, the buoyancy control unit 200 may be provided on the deck of the vessel 20, and may be provided above or below the sea level.

FIGS. 8 and 9 are views showing the mixing ratios of the fluids contained in the support according to the embodiment of the present invention.

As shown in FIG. 8, the total weight of the ship 20 may not be large when the structure 50 mounted on the ship 20 is small. In this case, the ratio of the fluid accommodated in the interior accommodating space of the support portion 100 may be high in liquid and low in gas. Accordingly, the support portion 100 supports the ship 20 with relatively low buoyancy.

On the other hand, when the structure is added in the state as shown in FIG. 8, the weight of the ship 20 may increase. That is, as shown in FIG. 9, when the additional structure 60 is mounted on the ship 20, the total weight of the ship 20 is increased.

In this case, the ratio of the fluid accommodated in the interior accommodating space of the support portion 100 may be high in gas and low in liquid. Thus, the support portion 100 supports the ship 20 with a relatively high buoyancy.

In this way, considering the total weight of the ship 20, the ratio of the fluid accommodated in the interior accommodating space of the support portion 100 is determined differently, so that the variation of the draft of the ship 20 is alleviated, The friction between them can be reduced.

This explains that liquid supply and gas extraction are performed at the same time, and liquid extraction and gas supply are performed simultaneously. However, according to some embodiments of the present invention, liquid supply, liquid extraction, gas supply, and gas extraction may be performed independently.

That is, when the draft of the ship 20 increases, only the gas supply is performed without extracting the liquid, only the liquid extraction is performed without the gas supply, or the liquid extraction and the gas supply can be performed at the same time. Likewise, when the draft of the ship 20 is reduced, only the liquid supply is performed without extracting the gas, only the gas extraction is performed without the liquid supply, or the gas extraction and the liquid supply can be performed at the same time.

In addition, regardless of the increase in the draft of the ship 20 or the decrease in the draft, the liquid supply, the liquid extraction, the gas supply, and the gas extraction can be performed independently to reduce the variation of the draft of the ship 20.

10 is a view showing a ship supporting apparatus according to another embodiment of the present invention.

Referring to FIG. 10, the ship supporting apparatus 11 includes a support unit 400, a buoyancy control unit 500, and fluid transfer units 610 to 650.

The shape and function of the support part 400, the buoyancy control part 500 and the fluid transfer parts 610 to 650 are similar to those of the support part 100, the buoyancy control part 200 and the fluid transfer part 300, Is omitted. Hereinafter, differences between the support unit 100, the buoyancy control unit 200, and the fluid conveyance unit 300 will be described.

The support portion 400 may include a plurality of different inner accommodation spaces 410 to 450. The plurality of inner accommodation spaces 410 to 450 are isolated from each other, and the fluid flow between the respective inner accommodation spaces can be blocked.

The plurality of inner accommodating spaces 410 to 450 may be provided along the long axis of the supporter 400, but the present invention is not limited thereto. For example, a plurality of internal accommodation spaces may be provided along the short axis of the support unit 400, and a plurality of internal accommodation spaces may be provided in a lattice form. Also, considering the weight distribution formed on the ship, the support part 400 may be divided into various forms, and a plurality of internal accommodation spaces may be provided.

The fluid conveyance units 610 to 650 may be connected to the plurality of the inner receiving spaces 410 to 450. Each of the fluid transferring units 610 to 650 independently transfers fluids, and the buoyancy control unit 500 may transfer fluids to the fluid transferring units 610 to 650. That is, liquid supply, liquid extraction, gas supply, and gas extraction can be performed for each of the plurality of internal storage spaces 410 to 450.

The size of buoyancy provided by each internal accommodation space can be determined according to the weight distribution of the ship or the posture of the ship. For example, when the weight of the bow of the ship increases, the buoyancy control unit 500 may increase the buoyancy of the inner receiving space located on the lower surface of the bow of the ship and may not increase the buoyancy of the remaining inner receiving space.

Or when the draft at the stern side is larger than that at the bow of the ship, the buoyancy control unit 500 reduces the buoyancy of the internal accommodation space located on the lower surface of the ship and increases the buoyancy of the internal accommodation space located on the lower surface of the ship And the buoyancy of the remaining internal accommodation space may not be increased.

As described above, according to the weight distribution of the ship or the attitude of the ship, the buoyancy of the plurality of the internal storage spaces 410 to 450 is independently controlled, so that the balance and the draft of the ship can be maintained more efficiently.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
