Cutout water hole 8 opens up area.
It is understood that in the present embodiment, only illustrate by the floor 2 being arranged in ballast tank and for vertical 3 structure of bone,
It is appreciated that in other embodiments, can also be arranged in ballast tank other can generate shadow to the circulation of ballast water
Loud structural member is as partitioning standards.Meanwhile it is appreciated that in the present invention with floor 2 and vertical bone 3 be divide foundation
Be: each floor 2 and vertical bone 3 being arranged in ballast tank will form inhibition, flowing water to the circulation of the ballast water in ballast tank
Hole 8 is provided with accordingly on floor 2 and vertical bone 3, so being divided with floor 2 and vertical bone 3, will be spaced by floor 2 and vertical bone 3
Each region out is as the region for being divided out described in the present embodiment.
In embodiments of the present invention, step S200 includes:
It step S210, is four grades by region division；
Step S220, the outflow sectional area summation in the region of four grades is determined respectively and flows into sectional area summation.
Specifically, region includes: the level-1 area 4 for being provided with ballast suction inlet 1 in step S210, discharge orifice and level-one are flowed out
The level-2 area 5 that region 4 is connected to, the tertiary zone 6 that outflow discharge orifice is connected to level-2 area 5, removes level-1 area 4, second level area
Level Four region 7 outside domain 5 and tertiary zone 6.The vertical bone 3 that will be flowed through between each region and ballast suction inlet 1 or 2 quantity of floor into
Row divides, and being provided with the region that the region of ballast suction inlet 1 connects for level-1 area 4, with level-1 area 4 between is level-2 area 5,
Connecting with level-2 area 5 is tertiary zone 6, and rest part is level Four region 7, by each region division grade.
In the present embodiment, the inflow discharge orifice of tertiary zone 6, level-2 area 5 and level-1 area 4 is respectively rear stage area
The outflow discharge orifice in domain 4.The discharge orifice 8 opened up on i.e. same floor 2 or vertical bone 3.
By the way that each region is divided into different brackets as foundation according to the region quantity flowed through between ballast suction inlet 1,
To the convenient outflow sectional area summation to each hierarchical region and flow into sectional area summation and calculate, and, facilitate determine it is each etc.
The individual region quantity in grade region, to reasonably arrange 8 position of discharge orifice and quantity.
In embodiments of the present invention, include: in step S300

Determine that the minimum outflow sectional area summation minimum of the hierarchical region flows into sectional area summation according to the maximum stream flow of ballast suction inlet 1；
Then, the region quantity of each grade is calculated separately, is cut with the minimum outflow sectional area summation and minimum flow into of the hierarchical region
Area summation divided by the hierarchical region quantity, that is, may know that the minimum outflow section for the discharge orifice 8 that each area requirement opens up respectively
It is long-pending to flow into sectional area with minimum；Finally, to open up aperture claimed range and discharge orifice 8 about discharge orifice 8 in Ship Design specification
The requirement for opening up position is condition, determines that its discharge orifice 8 opens up aperture and position in corresponding region.
Further, the quantity of the floor and vertical bone that need to open up outflow discharge orifice and inflow discharge orifice can be first calculated separately,
Then flowing water divided by setting outflow discharge orifice and is flowed into respectively with minimum outflow sectional area summation and minimum inflow sectional area summation
The quantity of the floor in hole and vertical bone calculates the sectional area for the discharge orifice 8 for needing to open up on each floor and vertical bone, then basis
Aperture, which is opened up, about discharge orifice 8 in Ship Design specification requires 8 quantity of discharge orifice for judging to need to open up on each floor and vertical bone.
Quantity and pore size are opened up with what this determined discharge orifice 8, finally opens up position about discharge orifice 8 according still further in Ship Design specification
The requirement set, determine discharge orifice 8 opens up position.
In embodiments of the present invention, the minimum outflow sectional area summation in the region of each grade is not less than twice of ballast tube respectively
Sectional area, the minimum sectional area for flowing into sectional area summation and being not less than twice of ballast tube respectively in each region of each grade.Pass through
The minimum outflow sectional area summation in the region of each grade and minimum inflow sectional area summation setting are not less than twice of ballast respectively
The sectional area of pipe, it is ensured that the ballast water flux density in each hierarchical region.
It in embodiments of the present invention, further include to outflow discharge orifice and the position for flowing into discharge orifice after step S340
Stren gsth test.Pass through the Stren gsth test to outflow discharge orifice and the position for flowing into discharge orifice, it is ensured that in ballast tank of ship
Floor 2 and vertical bone 3 structural strength, guarantee the structural strength of hull, avoid outflow discharge orifice and flow into discharge orifice arrangement
Ship's structural strength is caused to decline.
