Description

TECHNICAL FIELD [0001] The present invention relates to a floating dock including a rotating partition and a method for drying a floating structure using the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating dock including a rotating bulkhead and a method of drying a marine structure using the same.

When a ship or a large structure is to be built in a shipyard, large blocks are mounted on a large platform called a dock for finishing work.

In general, for efficient operation, the floating dock in the sea, rather than the land dock, may be combined with drying and decimating. The floating dock has a ballast tank therein. When the water is injected into the ballast tank, the floating dock sinks. When the water is discharged from the ballast tank, the floating dock floats up to the sea.

A typical floating dock has a rectangular shape that is long in one direction, and a square ship or an offshore installation is being dried on land or in a separate offshore floating dock.

The technique related to the floating dock is disclosed in Korean Patent Laid-open Publication No. 10-2014-0050792.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 1 is a perspective view of a floating dock having a rotating bulkhead according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating a rotating bulkhead rotated along a rail in the floating dock shown in FIG. 1, FIG. 4 is a plan view of a float-out in a floating dock according to an embodiment of the present invention. FIG.

1 to 4 show a floating dock 100, a dock main body 110, a rail 130, rotation barriers 120a and 120b (hereinafter also referred to as '120'), a dock center axis 10, A hull block 20, and a hull block 1 are shown.

A floating dock according to an embodiment of the present invention is characterized in that a rotary partition wall moves along a rail provided on a deck so that a hull block can be loaded out / floated out in any direction.

Here, when the ship is dried on the floating dock, a block for drying the ship is mounted on the floating dock, which is called a load-out. After the assembling of the mounted blocks is completed, the floating dock is submerged to float the assembled hull block, which is called float out.

The floating dock 100 according to the present embodiment includes a dock main body 110 having a deck of a polygonal plane.

The dock main body 110 is provided with a ballast tank so that when the water is injected into the ballast tank, the floating dock 100 sinks, and when the water is discharged from the ballast tank, the floating dock can be floated to the sea.

A rail 130 may be provided at the edge of the deck of the dock main body 110. In the drawing, the rail 130 is shown as being circular with a predetermined diameter centered on the dock center axis 10 in the vertical direction at the center of the deck, but this is merely an example, Of course, be applied.

Although the rail 130 is shown protruding on the deck of the dock body 110 in the figure, this is only an example, and if necessary, the rails 130 may be placed under the deck of the dock body 110 Of course, it can be invisible.

On the rail 130, at least one rotating partition 120 is provided. The rotary partition 120 is provided with a wheel (not shown) at a lower portion thereof and can move along the rail 130.

Although two rotary barriers 120 are shown in the drawing, the present invention is not limited thereto, and the scope of the present invention is not limited thereto, and one or more than three rotary barriers 120 may be provided Of course it is possible.

By moving the rotary partition 120 along the rail 130, the position of the rotary partition 120 can be changed as shown in FIGS. It is possible to easily switch the direction of the entrance or float-out advancement in which the hull block 1 is loaded-out without the dock main body 110 rotating due to the change in the position of the rotary partition 120. [

Referring to FIG. 3, when the hull block 1 assembled first in the seawall is loaded out to the floating dock 100 according to the present embodiment, the rotating partition 120 is vertically positioned on the seawall, And the hull block 1 located at the quay wall through the opened portion can be easily loaded out.

4, when the hull block 1 which has been dried or maintained in the floating dock 100 is to be floated out, the rotary partition 120 is rotated so as to open the direction to float out, Out.

This solves the problem that the conventional floating dock has to load-out or float out the hull block only in a predetermined direction due to the fixed partition, and it is possible to easily move the float dock in a desired direction To allow the hull block to be loaded out / floated out.

The rotating partition wall 120 according to the present embodiment can rotate around the partition wall central axis 20 which is placed in a vertical direction at the center of the rotating partition wall 120 itself. To this end, a motor (not shown) is installed below the rotating partition 120, and the motor is driven according to the driving signal to rotate the rotating partition 120 itself.

The rotary partition 120 is provided with facilities for drying or repairing the hull block 1 mounted on the dock main body 110 such as a crane and the state of the hull block 1 mounted in the dock in real time And a measuring unit for measuring it.

The rotary barriers 120 may be moved along the rails 130 so that the rotary barriers 120 may be moved to the center of the barriers 1, So that it is possible to smoothly work by rotating around the rotary shaft 20.

The floating dock 100 according to the present embodiment is provided with a control unit (not shown) to control movement and / or rotation of the rotating partition 120 depending on the load-out direction, the float-out direction, .

5 is a flowchart illustrating a method of drying a marine structure using a floating dock having a rotating bulkhead according to an embodiment of the present invention.

The drying method of the sea structure using the floating dock 100 having the above-described rotating partition wall can be carried out according to the following steps.

First, after the floating dock 100 is approached to the inner wall with the hull block to be mounted (step S200), the rotary partition 120 is slid along the rail so that the rotary partition 120 is disposed perpendicular to the inner wall S210). Through this, the portion of the hull wall facing the hull is opened, so that the hull block can be easily loaded on the floating dock 100 through the open portion (step S220).

It is possible to smoothly rotate the rotary partition wall 120 around the center axis 20 of the partition wall while performing various operations in the floating dock 100 with respect to the hull block (Step S230) .

Or the rotary partition 120 may be moved along the rail 130 to perform a predetermined operation on all sides of the hull block (step S240). In the case where there are a plurality of the rotating partition walls 120, facilities provided for each of the rotating partition walls 120 may be different. In this case, the rotating partition wall 120 is moved to a vicinity of a work site requiring work using the facility. This makes it possible to carry out the work in a considerably simpler manner compared to the case where a plurality of equipments have to be provided or it was very difficult to move the equipments to the work site.

After the work on the hull block is completed, a direction to float out the hull block is determined (step S250). When the direction to float out is determined, the rotary partition 120 is moved along the rail 130 so that the corresponding direction is opened (step S260). Thereafter, water is injected into the ballast tank to submerge the floating dock 100 so that the hull block floats on the sea and floats out (step S270).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.

100: floating dock 110: dock main body
