Description
Technical field
The present invention relates to ship domain, specially a kind of permanent ballast for improving vessel stability and reducing ship center of gravity.
Background technique
Vessel stability operates for safety of ship particularly important；Some ships for various reasons, in certain Loading conditions
Under, it may appear that the situation of stability deficiency, therefore huge security risk can be faced.
Vessel stability is improved, the primary method to eliminate safe hidden trouble is to reduce the center of gravity of ship.Ship center of gravity is lower, ship
What stability improved is more obvious.
In general, some ships reduce ship center of gravity using cement injection in the sky cabin of bottom, the disadvantage is that cement is close
Degree is smaller, needs a large amount of empty cabin (or empty cabin of big volume of compartment) that a large amount of cement is perfused, and the hollow cabin of Ship Design is limited, is difficult
Meeting has extra a large amount of empty cabin to carry out cement injection；Cement injection difficulty of constructing is big, and long construction period, needs a large amount of manpower
Or material resources reduce ship center of gravity.
In addition, some ships place specific casting pig in the sky cabin of bottom to reduce ship center of gravity, the disadvantage is that needing to entrust
The casting pig of cast iron manufacturer casting is held in the palm, the casting of cast iron manufacturer and procurement cycle are long, at high cost；It is placed in sky cabin not solid
It is fixed, ballast casting pig vulnerable to inertia force in ship's navigation influence and move, hit ship body construction, destructible ship ontology
Structure.
Summary of the invention
Present invention aims in view of the deficiencies of the prior art, and a kind of raising vessel stability is provided and reduces ship weight
Fixed ballast (steel plate) object of the heart reduces ship center of gravity and improves vessel stability, while specific lower cost and efficiently applying
Work.
It is achieved through the following technical solutions above-mentioned purpose:
A kind of permanent ballast for improving vessel stability and reducing ship center of gravity comprising:
Four sides of the shape of the first permanent ballast and the second permanent ballast, two permanent ballasts are "convex" shaped on one side,
Opposite is symmetrically two concaves on one side；
Vertical fixed flat steel is mounted on the both sides of permanent ballast one side "convex" shaped, while vertical fixed flat steel is mounted on fixation
Among the groove of two concaves of ballast another side；
And vertical fixed flat steel is by welding the first permanent ballast and the second permanent ballast and ship body construction knot
Together in one.
Respectively installation is vertical before and after "convex" shaped on one side of the shape of first permanent ballast and the second permanent ballast
Vertical fixed flat steel is installed on fixed flat steel, another symmetrical side respectively in the groove of two concaves, first layer
First permanent ballast and ship body construction are welded in one, and vertical fixed flat steel is by blocking fixation at " convex " and " recessed " slot
Ballast, and vertical fixed flat steel and the first permanent ballast, the second permanent ballast and ship body construction junction
It is welded in one, permanent ballast is prevented to be moved by inertia force in ship's navigation.
And permanent ballast is arranged close to as far as possible in the empty cabin of hull bottom, to greatly improve vessel stability.
The present invention has the advantages that
1. the density of fixed ballast (steel plate) object is big, the empty cabin of required installation is smaller, and to ship center of gravity is reduced, it is steady to improve ship
Property effect is the most obvious.
2. fixed ballast (steel plate) object is by described herein, fixed ballast (steel plate) object is blended in one, not by ship
Oceangoing ship navigation in inertia force influence and generate movement, will not more destroy or influence ship body construction.
3. cost is relatively low for fixed ballast (steel plate) object, short construction period is easy to construct.Due to fixed ballast (steel plate) object
It is not limited by the plate thickness of steel plate and material grade, shipbuilding enterprise can cut fixed ballast (steel with the tailing of steel plate
Plate) object and vertical fixed flat steel；Since monolithic fixed ballast (steel plate) object can manually be helped to transport, it is not required to loop wheel machine, so construction week
Phase is short and easy for construction.
Detailed description of the invention
Fig. 1 is first layer fixed ballast (steel plate) object figure of the invention；
Fig. 2 is the structural schematic diagram integrally overlapped of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of fixed ballast (steel plate) object for improving vessel stability and reducing ship center of gravity referring to FIG. 1-2, comprising:
Four sides of the shape of the first permanent ballast 1 and the second permanent ballast 2, two permanent ballasts are " convex " word on one side
Shape, opposite is symmetrically two concaves on one side；
Vertical fixed flat steel 3 is mounted on the both sides of permanent ballast one side "convex" shaped, while vertical fixed flat steel 3 is mounted on admittedly
Among the groove of two concaves of level pressure loading another side；
And vertical fixed flat steel 3 is by welding the first permanent ballast 1 and the second permanent ballast 2 and ship body construction
It is incorporated into one；
Respectively installation is vertical solid before and after "convex" shaped on one side of the shape of first permanent ballast 1 and the second permanent ballast 2
Determine band steel 3, vertical fixed flat steel 3 is installed on another symmetrical side respectively in the groove of two concaves, first layer
First permanent ballast 1 is welded in integrally formed fillet welding 5 with ship body construction, and vertical fixed flat steel 3 passes through " convex " and " recessed "
Permanent ballast, and vertical fixed flat steel 3 and the first permanent ballast 1, the second permanent ballast 2 and ship are blocked at slot
Body construction junction is welded in one, and fixed ballast (steel plate) object is prevented to be moved by inertia force in ship's navigation, from
And permanent ballast (steel plate) is influenced to move by inertia force in ship's navigation, will not more destroy or influence ship bulk junction
Structure.
And fixed ballast (steel plate) object is arranged close to as far as possible in the empty cabin 4 of hull bottom, therefore can substantially reduce ship center of gravity,
To greatly improve vessel stability.
The density of fixed ballast (steel plate) object is big, and the empty cabin of required installation is smaller, and to ship center of gravity is reduced, it is steady to improve ship
Property effect is the most obvious;Fixed ballast (steel plate) object is dissolved in one, is not influenced by inertia force in ship's navigation and generates shifting
It is dynamic, it will not more destroy or influence ship body construction;Cost is relatively low for fixed ballast (steel plate) object, and short construction period is easy to apply
Work.Since fixed ballast (steel plate) object is not limited by the plate thickness of steel plate and material grade, shipbuilding enterprise can use the side of steel plate
Angle clout cuts fixed ballast (steel plate) object and vertical fixed flat steel；Since monolithic fixed ballast (steel plate) object can be helped manually
Fortune, is not required to loop wheel machine, so short construction period and easy for construction.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
