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

There is tjemplon hull automatic balancing method and the system of ballast function

Technical field

The present invention relates to a kind of tjemplon hull automatic-balancing system, be mainly used in the self-equalizing of tjemplon (as ferryboat) hull, after lade, hull be adjusted to level.

Background technology

Tjemplon (as cargo-container ship) due to hull huge, after filling goods, hull being equal in weight everywhere can not be accomplished, the inclination of hull can be caused.In order to keep the balance of hull, needing when lade to regulate carrying capacity everywhere to keep substantially equal, causing very burden to loading work, not only affect work efficiency, also can not accomplish complete equilibrium.A kind of Chinese utility model patent of safety self-help balancing device for ship (notification number is CN1401540A) is had in prior art, its keystone configuration arranges the automatic control cabinet of hull in hull bottom, its center bottom is hull center of gravity position, utilizes its center of gravity effect to keep the stable of hull and balance.But this device does not act on substantially for the balance of tjemplon, hull weight balancing everywhere can not be regulated.

Summary of the invention

The object of the invention is to provide a kind of tjemplon hull automatic-balancing system with ballast function, to solve the unbalanced problem of hull that prior art exists.

Technical scheme of the present invention is: a kind of tjemplon hull automatic balancing method with ballast function, is characterized in that, comprise the following steps:

(1) four separate balance bunkers are at least provided with in the surrounding of the Ballast Tank of described hull bottom,

(2) the hull angle of inclination after lade is detected;

(3) water of the balance bunker being positioned at lower is drawn into the balance bunker of higher position, until stop pumping after hull level.

A kind of system implementing described tjemplon hull automatic balancing method, comprise the Ballast Tank and ballast water treatment system that are located at hull bottom, it is characterized in that, at least be provided with four separate balance bunkers in the surrounding of described Ballast Tank, connected by pipeline between each balance bunker, each pipeline is equipped with water pump, each water pump controls by balance controller, when the goods of hull draft is unbalance, regulate the water yield in each balance bunker, keep the balance of hull.

Described balance controller adopts sensing gyroscope instrument, take horizontal surface as benchmark, is automatically drawn into by the ballast water in the balance bunker of one end large for weight in the balance bunker of lightweight one end, until balance.

Described balance controller comprises water level detector and microcomputer controller, at the periphery of hull, several water level detector is set, the vessel draft depth signal detected is sent to microcomputer controller by water level detector, microcomputer controller controls the switch of relevant water pump and the conversion of pipe electromagnetic valve, automatically the ballast water in the balance bunker of one end large for weight is drawn in the balance bunker of lightweight one end, until balance.

Advantage of the present invention is: when one end weight of hull is larger, can in the balance bunker on trend opposite amount of makeup water, keep the horizontality of hull entirety.Meanwhile, balance bunker also has the effect of ballast cabin.Structure is simple, easily implements.

Accompanying drawing explanation

Fig. 1 is overall structure of the present invention (side) schematic front view;

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

Detailed description of the invention

See Fig. 1 and Fig. 2, a kind of tjemplon hull automatic-balancing system with ballast function of the present invention, comprise and be located at Ballast Tank 7 bottom hull 1 and the ballast water treatment system supporting with it (prior art), it is characterized in that, four separate balance bunkers 2 are at least provided with in the surrounding of the bottom of described Ballast Tank 7, connected by pipeline 5 between each balance bunker 2, each pipeline is equipped with water pump 4, each water pump 4 controls by balance controller 3, when the goods of hull draft is unbalance, regulate the water yield in each balance bunker 2, keep the balance of hull 1.

Described balance controller 3 adopts sensing gyroscope instrument, take horizontal surface as benchmark, cargo weight once hull one end is larger, the hull of this end will sink larger distance, hull will hitherward tilt, balance controller 3 detects this leaning angle, is automatically drawn into by the ballast water in the balance bunker 2 of one end large for weight in the balance bunker 2 of the one end on lightweight (opposite), until hull reaches basic horizontal.

Described balance controller 3 also can adopt water level detector 6 and microcomputer controller, at the periphery of hull 1, several water level detector 6 is set, the vessel draft depth signal detected is sent to microcomputer controller by water level detector, microcomputer controller controls the switch of relevant water pump and the conversion of pipe electromagnetic valve, automatically the ballast water in the balance bunker of one end large for weight is drawn in the balance bunker of lightweight one end, until balance.

In figure, pipeline 5 and water pump 4 are schematic diagrams, and water pump 4 can adopt the two-way water pump (changed by the change that turns to and flow to) drawn water, or the change (routine techniques) in the direction that realizes drawing water by the change of pipeline and valve.

The present invention's (static state) after hull draft goods gets final product work, and workflow (method) is:

First detect the hull angle of inclination after lade by balance controller 3, then the water of the balance bunker being positioned at lower is drawn into the balance bunker of higher position, until stop pumping after hull level.
