Description

[0001] Dry-dock for preventing inflow mud [

The present invention relates to a dry dock, and more particularly, to a dry dock for preventing inflow of tidal mud contained in seawater introduced into a dry dock through a lower drainage tank at the time of ship launch.

Generally, a dry dock structure refers to a facility constructed in a shipyard or a port to dry and repair a ship. It is a ship that has a length sufficient to allow a ship of a certain size or less to enter and exit a ship having a sufficient depth to launch the ship, Width and depth to connect with the sea, and the front, side walls and floor are made of reinforced concrete and the entrance is equipped with a gate.

1 is a conceptual view schematically showing a conventional dry dock.

1, a conventional dry dock is provided with a dock gate 20 between the dry dock 10 and the sea, and a drain sump 30 through which the seawater moves under the dock gate 20 .

Here, one end of the drain tank 30 is formed through the bottom of the dry dock 10, and the other end is formed through the bottom layer of the bottom of the seawater.

At this time, predetermined drainage lines (31) are further provided at one end and the other end of the drain tank (30), so that seawater is discharged into the dry dock (10) through the drain tank (30) .

The tidal mud at the bottom of the sea water together with seawater is structurally pumped to the dry dock 10 through the drainage tank 30 when the ship is in operation by pumping seawater into the dry dock 10 by using a pump 40, Respectively.

After the completion of the launching process of the ship, the sea water poured into the dry dock 10 is forcibly pumped through the drain tank 30 and drained to the sea. At the bottom of the drain dock 10, The included tidal mud remains.

In order to collect the tidal mud left on the floor of the dry dock 10 and to clean the dry dock 10 thoroughly, a lot of manpower and equipment must be mobilized, and a long period of time is required, Occurs.

In addition, the cost required for cleaning the inside of the dry dock 10 and for collecting tidal mud is excessively increased, and subsequent processes such as ship manufacturing and repair are delayed, resulting in a great cost loss.

(0001) Korean Patent Publication No. 10-2007-0044851 (published on May 02, 2007) (0002) Korean Utility Model Registration No. 20-0282821 (issued on July 23, 2002)

The present invention has been made to solve the above problems and provides a dry dock for preventing inflow of tidal mud contained in seawater introduced into a dry dock through a lower drainage tank when the ship is launched I have to.

Another problem of the present invention is to provide a dry dock for preventing inflow of tidal mud which can reduce the use of the pump by half, thereby reducing power consumption.

According to an aspect of the present invention, there is provided a dock comprising: a dock housing formed to be lower than a sea level and recessed at a predetermined depth from a ground surface, the dock housing having a predetermined inner space; A gate, a seawater passage formed in the bottom of the dock gate for communicating the oceans with the inner space of the dock housing, and a pump installed in the seawater passage, wherein the dock gate comprises at least one through hole And a lid for opening or blocking the through hole.

And the through hole further comprises a valve.

Wherein the valve is a one-way flow-controlled hydraulic valve.

The present invention can prevent the inflow of tidal mud contained in seawater introduced into the dry dock through the lower drainage tank when the ship is launched, so it is necessary to clean the dry dock and to collect the manpower required for collecting the tidal mud, .

In addition, since the present invention can carry out a subsequent process immediately after draining the seawater, the entire ship manufacturing process time is shortened.

Further, the present invention can reduce the use of the pump by half, thereby reducing the use of electric power, thereby reducing the cost.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate preferred embodiments of the invention and, together with the description, serve to further the understanding of the technical idea of the invention, And shall not be construed as interpretation.
1 is a conceptual diagram schematically showing a conventional dry dock,
FIG. 2 is a schematic view showing a dry dock for preventing inflow of tidal mud according to an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a dry dock for preventing inflow of tidal mud according to the present invention will be described in detail.

FIG. 2 is a schematic view showing a dry dock for preventing inflow of tidal mud according to an embodiment of the present invention.

Referring to FIG. 2, the dry dock for preventing the inflow of tidal mud according to the preferred embodiment of the present invention includes a dock housing 100, a dock gate 200, a seawater passage 300, and a pump 400 This will be described in detail as follows.

The dock housing 100 is formed to be recessed at a certain depth from the ground lower than the sea level.

In addition, a predetermined internal space is provided, and the ship is accommodated in the internal space, and the manufacturing and repairing process of the ship proceeds.

The dock gate 200 opens or shuts the internal space of the dock housing 100 against the ocean, and the ship enters and exits through the dock gate 200.

The seawater circulation passage 300 is formed in the bottom of the dock gate 200. One side of the seawater circulation passage 300 passes through the seawater bottom layer of the ocean and the other side passes through the bottom of the dock housing 100.

The pump 400 is installed in the seawater circulation passage 300. The seawater stored in the dock housing 100 is forcibly pumped to the sea through the seawater circulation channel 300.

At least one through hole 210 is formed in the dock gate 200 at a predetermined height and a lid 220 is installed in the through hole 210.

That is, when the seawater is to be introduced into the dock housing 100, the seawater is naturally flowed through the through hole 210 and, on the other hand, in order to discharge the seawater to the sea, The pump 400 pumps the seawater by forced pumping.

Meanwhile, the valve 230 may be further provided in the through hole 210. In order to prevent the reverse flow of the seawater, seawater is introduced only in the direction of the dock housing 100, (one-way) flow-controlled hydraulic valve.

In addition, a predetermined filtering network 310 may be installed at one end and the other end of the seawater circulation channel 300 to filter foreign matter having a predetermined size or more.

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, And will fall within the scope of the appended claims.
