Method and system for automatically balancing ship body of large cargo ship with ballast function

Abstract

The invention discloses a method and a system for automatically balancing the ship body of a large cargo ship with a ballast function. At least four mutually independent balance cabins are arranged on the periphery of the bottom of the ship body; the tilt angle of the ship body after cargo loading is detected; water inside the balance cabins positioned at lower positions is pumped into the balance cabins at higher positions, and the pumping of the water is stopped until the ship body is horizontal. According to the system implementing the method, the balance cabins are connected through pipelines, a water pump is mounted on each pipeline, each water pump is controlled by a balance controller respectively, and when cargo loaded in the ship body is out of balance, the water amount inside each balance cabin is adjusted to keep the ship body balance. The method has the advantage that when the weight at one end of the ship body is higher, water can be automatically supplemented into the opposite balance cabins to keep the integral horizontality of the ship body. Meanwhile, the balance cabins further play roles of ballast cabins. The system is simple in structure and easy to implement.

Description

technical field

[0001] The invention relates to an automatic balancing system of a large cargo ship hull, which is mainly used for automatic balancing of the hull of a large cargo ship (such as a ferry boat), and adjusts the hull to the level after loading cargo. Background technique

[0002] Due to the huge hull of a large cargo ship (such as a container cargo ship), it is impossible to equalize the weight of all parts of the hull after being filled with cargo, which will cause the hull to tilt. In order to maintain the balance of the hull, it is necessary to adjust the loading volume of each place to keep the load basically equal when loading the cargo, which causes a lot of trouble to the loading work, not only affects the work efficiency, but also makes it impossible to achieve a complete balance. In the prior art, there is a Chinese utility model patent (notification number: CN1401540A) for a ship safety self-rescue balancing device. Its main structure is to set an auto...
