Description

Creed Ship Drying Float Dock {Floating dock for shipbuilding}

The present invention relates to a floating dock, and more particularly, to a floating dock capable of maintaining flatness and straightness within a range suitable for the construction of a ship.

Generally, a dock is a facility built in a shipyard or a port to build and repair a ship. The dock is a length, a width, and a width sufficient to allow a ship to enter and close to the sea having a sufficient depth for launching the ship. It is a dry dock and quadrilateral steel box that digs deep into the sea, connects the side walls and floors with reinforced concrete or piles, and installs a dock gate at the entrance. There is a floating dock that has a tank and controls the degree of flotation by controlling the storage of seawater in these tanks.

The floating dock was mainly used only for repair of the vessel, which shows that the tank is submerged by filling the inner tank with seawater to submerge the dock, dragging the vessel into the floating dock, and then pumping the seawater inside the tank. The deck floats above the surface with the ship.

Since the floating dock itself is similar to a huge vessel, when a load is applied to it, the entire floating dock is tilted or distorted by the load, and the deck used as a workshop is also bent or distorted. It was deemed inadequate for the construction of new ships requiring precise straightness.

The present invention is to solve the above problems, by dividing the ballast tank of the floating dock in sub-units, and by adjusting the ballast amount of each ballast tank independently, the position of the object placed on the deck of the floating dock Or by adjusting the discharge amount of the ballast corresponding to the load of the object from the other ballast tanks around the buoy to adjust the posture in response to the load of the object, the buoy can maintain the straightness and level of the deck used as a workplace Its purpose is to provide poison.

In order to achieve the above object, the present invention provides a ballast tank having a ballast tank arranged on the deck and sidewalls in a symmetrical form and a symmetrical form, and a pumping system for adjusting the level of the ballast. Water level sensor for detecting the internal water level and deformation sensor provided on the deck and sidewall surface of the floating form dock, deformation sensor for measuring the deformation of the deck and sidewall, system for calculating the variation of the dock, system for controlling the ballast pumping system Is achieved.

The pumping system is preferably composed of inlet valves, outlet valves, pumps, individual ballast valves and distribution pipes connected to each ballast tank on a row basis.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 of the accompanying drawings is a perspective view of the present invention aquaculture dock.

As shown, the floating dock 100 is composed of a box-shaped pontoon (110) located in the center and side walls 120 formed on both sides of the pontoon 110, the pontoon 110 and both side walls 120 ) Are all equipped with a ballast tank. Drying or repair work of the ship is made in the deck 112, the upper portion of the pontoon (110).

The ballast tanks embedded in the pontoons 110 and the sidewalls 120 are arranged symmetrically and symmetrically, and allow to individually control drainage and water supply for each ballast tank. It is desirable to have a water level sensor that can detect the level of water.

In addition, the pontoon and the side wall is preferably provided with a deformation detection sensor for each predetermined position to be able to detect the deformation of the hull of the floating form dock 100.

2 is a layout view of the ballast tanks of the present invention.

Each ballast tank is preferably divided as much as possible in order to easily adjust the deformation of the aquaculture dock, so that the pumping system is also appropriately placed therein.

The ballast tank 200 embedded in the deck 100 and the side wall 120 of the floating dock is divided into subunits, and the arrangement state thereof is symmetrical up and down and left and right. Therefore, if the ballast corresponding to the weight is removed from the ballast tank 200 corresponding to the position of the object placed on the deck, the deck of the floating dock is not deformed.

As shown, the pumping system for adjusting the ballast amount of the ballast tank 200 is composed of a pump 220 and the valves (210, 230 and 250).

This part will be described in detail, the ballast tanks 200 divided into sub-units are controlled inflow and outflow of the ballast by the operation of one pumping system of the heat unit.

Each heat pumping system includes an inlet valve 210 for controlling the inflow of seawater, an outlet valve 230 for controlling the outflow of seawater, a distribution pipe 240 connected to each ballast tank 200, and each ballast tank. It is provided with a pipe connected to 200 is made of a ballast valve 250 for controlling the entrance and exit of the seawater into the individual ballast tank by the opening and closing operation.

When the outlet valve 230 is locked, the inlet valve 210 is opened, and the pump 220 is operated, seawater flows into the inlet valve 210 and is supplied to the distribution pipe 240. ) To each ballast tank 200 along the tube. The discharge of seawater is reversed.

The adjustment of the inflow amount of the individual ballast tank 200 is controlled by opening and closing of the ballast valve 240 provided in the pipe connected to each ballast tank 200.

3 of the accompanying drawings is a state diagram used in the form of dock for the present invention ship building.

As shown, the floating dock is moored in close proximity to the land workshop 300, the hull blocks 500 assembled in the land workshop 300 to the float dock 100 by using the crane 400 Will be mounted. When the hull block 500 is mounted, the deck of the flotation dock 100 is mounted before and after the ballast tank corresponding to the weight of the hull block 500 is discharged from the ballast tank corresponding to the mounting position of the hull block 500. You can keep the same state. Therefore, since the deck of the floating dock 100 can have a constant flatness and straightness, it is possible to construct the vessel in the floating dock 100.

The present invention is provided with a ballast system, which is divided into subunits, arranged in front and rear, and symmetrically, and has a system for predicting and calculating changes in posture and shape of the farm. Since the ballast can be adjusted according to the load on the deck and can be judged by the measurement system, the flatness of the deck can be maintained to the extent necessary for the ship's construction.

In addition, the present invention enables the construction of the ship in the floating dock to reduce the cost of the construction of the dock, and also to reduce the use of land to reduce the cost of construction of the entire ship. Therefore, there is an effect of increasing the price competitiveness in the shipyard using the incubated dock of the present invention.
