Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a catamaran floating dock.

As is well known, conventional floating docks have a concave shape in the vertical plane and are expensive to construct.

The present invention has been made by focusing on the above points,
That is, the purpose of the present invention is to use a self-propelled used hull, which can accommodate ships of equal size in terms of buoyancy, and which is much cheaper than conventional hulls. , it is possible to move to the desired sea area without the need for a boat or the like. To provide a catamaran type floating dock.

Another object of the present invention is to provide a catamaran-type floating dock that can adjust the degree of sinking of the entire floating dock depending on the total displacement tonnage and water intake of a ship accommodated within the dock body.

Still another object of the present invention is to provide a catamaran type floating dock which can also be used as a dry dock by providing a work platform that can be raised and lowered within the dock body.

Next, embodiments of the present invention that can achieve the above objects will be described in detail with reference to the accompanying drawings.

1 shows two self-propelled used hulls, all of the equipment on the deck and inside the hull has been removed, and the engine,
The screw, steering, and other things necessary for self-propulsion were left in place, and everything else was removed as appropriate.

Reference numeral 2 indicates a dock body, and the hulls 1, 1 are attached to the left and right sides of the dock body 2 through girders. A water tank 3 is provided on the outside of the hold of the hulls 1, 1 attached to the left and right sides of the dock body 2, and seawater can be injected into and drained from the water tank 3. That is, in the illustrated example, a movable plate 5 that moves up and down by hydraulic pressure is provided inside the water inlet 4, and a desired amount of seawater is injected or drained by remotely controlling the movable plate 5. This is designed to adjust the degree of sinking of the entire floating dock and to maintain balance when a ship or the like enters the central dock body 2 and a load is applied.

Reference numeral 6 indicates watertight doors installed at the front and rear of the dock body 2, which are rotated by hydraulic pressure and configured so that when the doors are closed, the inside and outside of the dock body are watertightly shut off, allowing the seawater inside to be discharged. It can also be used as a dry dock.

Reference numeral 7 indicates a workbench installed in the dock body 2 so as to be movable up and down by hydraulic pressure. The workbench 7 can be lifted out of the water and used as a dry dock.

In addition, in Fig. 4, 9 is a hoist rail,
10 is a hoist mounting plate running on the rail 9; in FIGS. 2 and 4, 11 is a working deck stretched over the hull; and in FIGS. 1 to 3, 12 is a crane.

In the configuration described above, depending on the total displacement tonnage and water intake of the ship accommodated in the dock body 2, an appropriate amount of seawater is injected into the water tank 3 or drained from the water tank 3, and the floating dock is constructed. In addition to determining the degree of sinking as well as maintaining balance, the work deck 11 can be used for the ship accommodated in the dock body 2 through the watertight door 6, or the deck of the existing hull 1, 1 can be used. In addition, the ship is fixed on the work platform 7 to drain the seawater inside the dock body 2, and the work platform 7 is raised to perform work in a so-called dry dock state. Furthermore, if necessary, the vessel will move to the desired sea area to carry out work.

Although two embodiments of the present invention have been described above, the present invention is not limited thereto, and the design may be modified as follows.

() A girder 8a integrated with the girder 8 between the hulls 1, 1 and the dock body 2 as shown in FIG.
(In the figure, reference numeral 9 indicates a hoist rail).

() Both ends of the girder connecting the dock body 2 and the hulls 1 and 1 may be fixed to the keel by passing through the hull.

() As shown in Figures 2 and 5, girder 8
A brace 13 may be provided at 8a to reinforce the mechanical strength.

() When the ship's interior rigging is removed, some or all of the cabin and various facilities necessary for daily life may remain.

() Depending on the total displacement tonnage and water intake of the ship accommodated in the dock body 2, or according to the total weight of the ship placed on the work platform 7, the amount of water poured into the water tank 3 is adjusted to the degree of sinking of the entire floating dock. It may also be calculated and automatically performed by a computer in connection with the above.

As mentioned above, the present invention utilizes a second-hand self-propelled hull, and in terms of providing buoyancy, it is possible to accommodate ships of equal size at a much lower cost than conventional hulls. At the same time, it is possible to move to a desired sea area without the need for a dock boat, etc., and it is also possible to adjust the degree of sinking of the entire floating dock according to the total displacement tonnage and water intake of the ship accommodated within the dock body. Furthermore, by providing the dock body with a watertight door that can be opened and closed, and by providing a work table that can be raised and lowered within the dock body, it can also be used as a dry dock.
