Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to FIGS. 2 to 4 attached hereto.

FIG. 2 is a schematic view of a ballast system of a ship according to the present invention, FIG. 3 is an installation view of a ballast system of a vessel according to the present invention, and FIG. Fig.

2 to 3, the ballast system of a ship according to the present invention mainly includes a ballast tank 100, a main pipeline 200, a branch pipe 300, and a valve 400 .

The ballast system of the present invention according to the present invention is designed to minimize the use of pipes to simplify the structure and to facilitate ease of maintenance by facilitating the approach of the operator. In order to improve the ease of maintenance, It is a ballast system.

First, the ballast tank 100 is disposed below the upper deck D.

The ballast tank 100 stores the ballast water so that the center of gravity of the vessel S can be downwardly stably navigated.

In other words, in the case of a cargo ship, in order to solve the difficulty in balancing the ship because the depth of the ship is lowered when the cargo is not loaded on the ship, the ballast water is supplied to the ballast tank 10 to control the depth of the ship do.

Since the ballast water in the ballast tank 100 increases the resilience of the ship S, it is recommended that the International Maritime Organization (IMO) carry more than 30% of the cargo load. However, this ballast water has been pointed out as a cause of disturbing the marine ecosystem. Therefore, the International Maritime Organization has concluded an international convention on ballast water treatment in 2004, And must be installed or exchanged on the high seas.

4, the ballast tank 100 is installed in the ship S so as to be disposed at the port and starboard positions, respectively.

In addition, the ballast tank 100 may be provided with a plurality of divided spaces of the vessel S.

The upper part of the upper deck D and the upper part of the ballast tank 100 may be integrally formed or the upper deck D and the ballast tank 100 may be integrally formed with each other. A predetermined space may be formed between the upper portions of the first and second substrates 100 and 100.

In addition, the ballast tank 100 is provided with a drainage system (not shown) for discharging the stored ballast water.

Meanwhile, the inner wall of the ballast tank 100 may be waterproof coated to prevent corrosion due to seawater or the like.

Next, the main pipeline 200 serves to supply the ballast water to the ballast tank 100.

The main pipeline 200 is installed at one side of the ballast tank 100.

At this time, the main pipeline 200 is supplied with ballast water from a ballast water supply device (not shown), and is installed so as to pass through one side of the ballast tank 100 and connect to the inside thereof.

The main pipeline 200 mainly includes a supply line 210 and a branch line 220.

The supply line 210 is installed to pass through one side of the ballast tank 100 and is a pipeline for transferring the ballast water supplied from the ballast water supply device into the ballast tank 100.

The branch line 220 is connected to the supply line 210 and is provided with a branch pipe 300 to be described later.

The branch line 220 is connected to the supply line 210 and extends horizontally to an upper position of the ballast tank 100.

That is, when the supply line 210 installed through the ballast tank 100 is disposed vertically through one side of the ballast tank 100, the branch line 220 is positioned at a position where the vertical direction of the supply line 210 ends And corresponds to a portion that is bent and horizontally arranged in the horizontal direction.

The reason why the branch line 220 is extended to the upper portion of the ballast tank 100 to horizontally arrange the branch line 220 is to prevent the ballast water from being submerged in the ballast water when the ballast water is stored in the ballast tank 100, So as to prevent the branch line 220 from being corroded by the seawater.

FIG. 4 is a top view of a ship equipped with a ballast system according to the present invention. As shown in FIG. 4, the main pipeline 200 includes a ballast tank 100, respectively.

That is, the ballast water can be supplied to the ballast tank 100 by supplying the ballast water from the ballast water supply device at a specific position to the position of each ballast tank 100 through one pipe.

Next, the branch pipe 300 is a part for injecting the ballast water directly into the ballast tank 100 to inject the ballast water.

A plurality of branch pipes 300 are installed in the branch lines 220 of the main pipeline 200 at regular intervals.

At this time, the branch pipe 300 is partially exposed to the upper portion of the upper deck D, and the end is folded back into the ballast tank 100 to be connected.

The branch pipe 300 is installed adjacent to the branch line 220 at regular intervals in the branch line 220 of the main pipeline 200 disposed above the ballast tank 100, You can install it with minimal use.

In other words, since the plurality of branch pipes 300 installed in the main pipeline 200 are formed to have a short length, a separate support installation is not required, thereby simplifying the structure and greatly reducing the material cost.

The branch pipe 300 is connected to the branch line 220 of the main pipeline 200 so that a portion exposed above the upper deck D is bent at a right angle as shown in FIGS. It may bend gently in the form of

Next, the valve 400 serves to control the flow of ballast water in injecting the ballast water.

The valve 400 is installed in the branch line 220 of the main pipeline 200 installed to be exposed on the upper deck D.

That is, it is installed on one side of the branch line 220 exposed on the upper deck D so that the operator can easily perform the maintenance of the valve 400.

Also, since the valve 400 is installed in the ballast tank 100 and is locked in the ballast water, the valve 400 can not be accessed by the operator, and a remote type valve for controlling the valve 400 can be used.

The valve 400 may be exposed to the upper portion of the upper deck D and operated by an operator. The operator may manually or electronically connect the ballast water to the ballast tank 100 Or automatically opened and closed to allow the user to open the door automatically.

In addition, since the valve 400 is disposed to be exposed on the upper deck D, the contact of the ballast water can be blocked by locking the valve 400, thereby extending the service life of the valve 400.

In addition, a separate casing (not shown) is provided in the valve 400 and the branch line 220, which are installed to be exposed to the upper deck D, to protect them from rainwater and the like, .

In addition, a marking unit (not shown) may be further provided to identify an exposed area where the valve 400 and the branching line 220 of the upper deck D are installed.

Hereinafter, the operation of the ballast system of the ship described above with reference to Figs. 3 to 4 will be described.

First, the ballast water supplied from a separate ballast water supply device for supplying ballast water is transferred into the ballast tank 100 through the supply line 210 of the main pipeline 200.

Thereafter, the ballast water is transferred to the branch line 220 connected to the supply line 210 of the main pipeline 200, and a plurality of branch pipes 220 provided in the branch line 220 horizontally disposed above the ballast tank 100, The ballast water is transferred to the ballast water tank 300.

Thereafter, the ballast water is delivered through the branch pipe 300, which is exposed to the upper portion of the upper deck D of the vessel S, and the ballast water flow is controlled through the valve 400 installed in the branch pipe 300 .

At this time, the valve 400 may be separately operated for each branch pipe 300, or may be set to be simultaneously opened or closed at the same time.

Meanwhile, the ballast water delivered through the branch pipe 300 is supplied to the ballast tank 100 through the branch pipe 300 bent to be connected to the inside of the ballast tank 100 again.

At this time, the end of the branch pipe 300 bent to be connected to the inside of the ballast tank 100 is preferably disposed above the level of the ballast water level.
