Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rolling control system,

The present invention relates to a system for controlling right and left rolling of a ship, specifically, a ballast tank system for balancing an existing ship is removed, and the seawater introduced from the front of the ship is transferred to the rear of the ship, Ballast system including a pipeline and a left-right rolling prevention function of a ship by controlling a valve that maintains the balance of the ship by controlling the load of the left and right strings by controlling the amount of seated water discharged and discharged.

Generally, the ship is equipped with a ballast system for adjusting the draft and trim. This ballast system basically includes a plurality of ballast tanks provided in the hull and a ballast pump for supplying and draining ballast water to and from the ballast tanks have.

The ship's ballast tanks are intended for safe navigation by lowering the center of gravity of the ship by loading and unloading cargo. Several ballast tanks are installed symmetrically on the left and right sides of the ship. do.

The ballast water supplied to the ballast tank to hold the ship in the center thereof is called a ballast water. The ballast water is called a ballast water, which is filled in a tank of empty ship to catch the slope and weight of the ship, In general, when the ship is not loaded with goods, the depth with which the ship is immersed in water becomes low, making it difficult to balance the ship. Therefore, ballast water is filled into the ballast tank so that the ship can be navigated even when the load is not loaded. .

Such a conventional ballast system is characterized in that the ballast pump is usually installed in the engine room b together with the main engine or in the pump room a located along the cargo pump, The complex piping (c) and valve (d) are expensive to install and difficult to maintain due to the need to transport seawater through the seawater supply / discharge lines and the stripping line for each tank, The energy loss due to tube friction and the power consumption of the ballast pump become relatively large during transportation.

In addition, in the voyage of the ship, the process of discharging and discharging the marine water to the ballast tank is repeated according to the amount of loading and unloading of the cargo. During the operation of various solid matters such as sediment and marine life, It remains in the form of sediment in the ballast tank, and various solid matters remaining in the ballast tank are discharged to the outside together with the marine water when the cargo is loaded, thereby disturbing the surrounding marine ecosystem.

That is, if the environment of the marine ecosystem is discharged from another place due to the voyage of the ship, the ballast water filled in the ballast tank in a certain marine ecosystem is contaminated by the polluted marine ecosystem by the discharged ballast water It will be done.

As a countermeasure, the International Maritime Organization plans to install a facility for the treatment of ballast water on all ships in order to solve the problem of international marine environmental pollution caused by discharge and exchange of ballast water of ships as part of the regulation have.

However, the facilities for the treatment of ballast water are self-disinfection systems for ships, and they use technologies including irradiation of filters, ultraviolet rays, and spraying of chemical biocides. .

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited by the scope of the present invention.

Referring to FIG. 2, the ballastless system including the left-right rolling prevention function of the ship by the valve control according to the present invention is characterized in that the ballast system located at the lower left and right sides of the ship and inflowing seawater, A pair of body struts 100; A pair of inlet pipes (200) connected to the body cavity (100) and transferring seawater flowing from the body cavity (100); A pair of curved piping (300) connected to the introduction pipe (200) and transferring upwardly curved and introduced seawater toward the deck of the ship; A pair of inflow water control valves 210 mounted on one side of the introduction pipe 200 for controlling the amount of the sea water transferred to the curved pipe 300; A pair of discharge pipes (400) connected to the curved pipe (300) and discharging the seawater discharged from the curved pipe (300) to the left and right ends of the stern; A pair of drain water control valves 410 installed at one side of the discharge pipe 400 and controlling the discharge amount of the discharged sea water and connected to the inflow water control valve 210 and the drain water control valve 410, And a control unit 500 controlling the rolling of the ship by controlling the drainage control valve 210 and the drainage control valve 410 to adjust the flow rate of the retention of the pair of curved pipes 300.

Specifically, as shown in FIG. 2, seawater pushed in due to the navigation of the ship is introduced through a pair of artificial stres 100 formed at the lower end of the ship, that is, at the portion where the player sinks below the sea level.

The inflowing seawater is delivered to the inlet pipe 200 connected to the body cavity 100 and then discharged to the rear of the vessel through the curved pipe 300 and the outlet pipe 400 in sequence.

2, the curved pipe 300 is curved upward toward the deck of the ship, and the inlet pipe 200 and the outlet pipe connected to the front end and the rear end of the curved pipe 300 400 are provided with an inflow water control valve 210 and a drain water control valve 410 for controlling the seawater transferred to the curved pipe 300 and the discharged seawater.

In addition, the controller 500 may include a tilt sensor 510 (not shown) capable of detecting a tilt of the ship in the inside thereof, specifically, a gyro sensor, and may include a pair of left and right inflow control valves (210) and the drain water control valve (410).

3, when the tilt sensor 510 (not shown) senses that the tilt of the ship is biased to the right side, the control unit 500 controls the right side The inflow water control valve 210 of the line is closed and the drain water control valve 410 is opened to the maximum to empty the seawater in the right curved line 300. Conversely, And the drain water control valve 410 is closed to fill the left curved pipe 300 with seawater, thereby increasing the load on the port by the weight of seawater, thereby suppressing the rolling of the hull which is skewed toward the starboard.

On the contrary, when the tilt sensor 510 (not shown) senses that the inclination of the ship is shifted to the port, the control unit 500 closes the inflow water control valve 210 on the left line and the drain water control valve 410, The drain water control valve 210 is opened to the maximum and the drain water control valve 410 is closed to open the right curved pipe 300, By increasing the weight of sea water by filling seawater, the starboard load is increased to suppress the rolling of the hull which is inclined to the N port.

Accordingly, since the right and left rolling of the ship can be effectively suppressed, the existing ballast tank system can be sufficiently replaced, and the same effects as those of the existing ballast tank system can be obtained by using a pair of right and left body straps 100, 200, the curved piping 300, and the discharge piping 400. In this case,

2 and 4, the curved pipe 300 includes a gas discharge valve 310 for discharging gas existing in the curved pipe 300 on one side, and the gas discharge valve 310 are connected to the control unit 500 and controlled by the control unit 500.

That is, due to the structure of the upwardly curved pipe 300, the air transferred together with the inflow of seawater can stay inside the curved pipe 300. As shown in FIG. 4, And a bubble detection sensor 320 for detecting bubbles in the curved pipe 300. When the bubble detection sensor 320 is connected to the control unit 500 and bubbles are detected in the curved pipe 300, And a system for discharging the bubbles by opening the gas discharge valve 310 in the control unit 500 so that the flow of seawater can be smoothly performed through the discharge of the gas quickly.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
