Abstract
A ballastless system including a left-right rolling preventing function of a ship by valve control according to the present invention is a ballastless system that is located at the lower left and right sides of a ship and includes a pair of body straps 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.
Therefore, the present invention can replace the ballast tank system of existing vessels to replace the ballast tank system of existing vessels, thereby providing a pair of body straps 100, an inlet pipe 200, a curved pipe 300, and a sea water flowing through the outlet pipe 400, The current left and right current loads of the ship can be controlled by controlling the flow rate of the water remaining in the curved pipe 300 so as to prevent the left and right rolling of the ship without the ballast tank system and to maintain the balance of the ship do.
Description
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. .
