Description
Technical field
The present invention relates in water dive, in buoyancy aid cabin free surface curing technology field, particularly relate in a kind of water dive, liquid level solidification equipment in buoyancy aid cabin.
Background technology
The problem of rocking greatly with free surface fluid is very important mechanics problem in ocean freight, aeronautical engineering, petrochemical complex and nuclear reactor structure engineering, its liquid level to rock greatly the safety issue caused of common occurrence.
Stability is one of main performance index guaranteeing various marine float safe navigation and operation, and corresponding specification has all been formulated in current countries in the world, as the Main Basis judging stability in ship design or navigation.Free surface has and important influence latent, buoyancy aid stability.In recent years, the ship capsize accident caused because of various natural artificial origin is of common occurrence, and in these accidents, many Stability of Ship deficiencies that all causes with free surface are relevant.Such as, in " 11.24 " worst shipwreck in the shock whole nation in 1999, " large Shun " number ship sinks in stormy waves, dead 282 people in 304 passengers, according to post-survey, the sinking of this ship and the impact of free surface make stability disappear much relations, moreover, when free surface fluid shakes, impact effect has destructive effect to marine hydraulic hold border.
Summary of the invention
The technical problem to be solved in the present invention how to overcome the deficiencies in the prior art, provide in a kind of water dive, liquid level solidification equipment in buoyancy aid cabin.
The technical scheme that the present invention adopts for achieving the above object is: dive in water, liquid level solidification equipment in buoyancy aid cabin, comprise hydraulic actuating cylinder, rigid cover plate, guidepost, described rigid cover plate is rectangular, corner is provided with sleeve, the upper end of described rigid cover plate is provided with " day " font rigid frame, and described hydraulic actuating cylinder is connected by the middle part of cylindricality hinge with described rigid frame, and described guidepost has four, corresponding with the described sleeve on described rigid cover plate, be socketed in described sleeve.
Further: the trip distance of described hydraulic actuating cylinder is 3000 ~ 4000mm.
Further: the thickness of described rigid cover plate is 3 ~ 5mm.
Further: the internal diameter of described sleeve is 140 ~ 150mm.
The invention has the advantages that and drastically increase boats and ships etc. without the initial stability under free surface of water effect and large angle stability, greatly improve stability and the safety of caisson etc., structure of the present invention is simple, practical, has market outlook widely.
Accompanying drawing explanation
Fig. 1 integral structure schematic diagram of the present invention.
Detailed description of the invention
Dive in water, liquid level solidification equipment in buoyancy aid cabin, comprise hydraulic actuating cylinder 1, rigid cover plate 2, guidepost 3, described rigid cover plate 2 is rectangular, corner is provided with sleeve 21, the upper end of described rigid cover plate 2 is provided with " day " font rigid frame 22, and described hydraulic actuating cylinder 1 is connected by the middle part of cylindricality hinge with described rigid frame 22, and described guidepost 3 has four, corresponding with the described sleeve 21 on described rigid cover plate 2, be socketed in described sleeve 21.
The trip distance of described hydraulic actuating cylinder 1 is 3500mm, and the thickness of described rigid cover plate 2 is 3mm, and the internal diameter of described sleeve 21 is 150mm.
The present invention carries out design interpolation in Design and manufacturing process such as submarine, boats and ships, caissons.Submarine and boats and ships all carry out arranging interpolation the present invention in the cabins such as main ballast tank, trim adjustment water tank, fresh water tank, fuel oil tank, for caisson, before caisson making is built, carry out the sleeve in pre-buried the present invention, after adding pressure Cang Shui, complete installation the present invention, then carry out transportation by driving.The present invention carries out corresponding control by the hydraulic efficiency pressure system of hydraulic actuating cylinder 1 to liquid level.
Calculate with caisson example below:
Caisson swim stability system according to statics classical formulas derive and obtain.The stability of swimming of " gravity type quay design and construction specification " (JTS167-2-2009) regulation caisson represents with metacenter height m.Namely
m＝ρ-a
In formula:
ρ---metacentric radius;
A---caisson center of gravity is to the distance of centre of buoyancy.
Above formula is the metacenter height of caisson small angle oscillation under initial level transportation by driving state, namely represents the initial stability of caisson transportation by driving.The initial stability of small inclination supposition is the stable sufficient condition of caisson, instead of necessary condition.Caisson is different from boats and ships, need not ensure the initial stability under its horizontality, in general bar situation, even if caisson loses its initial stability under horizontality, but still can keep its stability of swimming in an inclined state.
The transportation by driving of caisson facts have proved, due to the polytropy of marine stormy waves, the existence of hawser trailing moment, inaccuracy or the separation of ballast leak, and caisson is transportation by driving under low dip or large heeling condition often.In addition, along with the appearance of the Large Caisson of various shape, the stability of swimming of caisson is difficult to be met.Adopt the method for the sleeping fortune that binds to ensure the safety of caisson, and the floating state of this inclination transportation by driving generally all need to be tried to achieve by model test.
Simply, effectively can improve caisson to swim stability by solidifying the mode of free surface.The concrete data of caisson are calculated as follows:
The long 21.4m of caisson, wide 11.4m, high 19m, arrange 1 road withe and 4 road across bulkheads in caisson.Caisson wall thickness 0.35m, partition wall thickness is 0.2m, the thick 1m of base plate.In pressurized compartment water 2m situation:
Height of gravitational center:
Total displacement of volume:
Front and back toe displacement of volume:
v
1＝26.78m
3
Caisson absorbs water:
Caisson height of center of buoyancy:
Center of gravity is to centre of buoyancy distance:
a＝y
c-y
w＝6.65-5.83＝0.82m
Metacentric radius:
Metacenter height:
m＝ρ-a＝1.18-0.82＝0.36m＜0.4m
Metacenter height does not meet the demands.
When after utilization solidification free surface technology, free surface effect disappears.Correlation computations is as follows:
Metacentric radius:
Metacenter height:
m＝ρ-a＝1.28-0.82＝0.46m＞0.4m
Metacenter height meets the demands.
Above-described embodiment, just in order to technical conceive of the present invention and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.The change of every equivalence done by the essence of content of the present invention or modification, all should be encompassed in protection scope of the present invention.
