The dried food and nuts submarine of cargo hold inflation

Technical field

The utility model relates to a kind of novel dried food and nuts Submarine Design, particularly this dried food and nuts submarine with the inflation of its cargo hold for its feature.

Background technology

In the World War II later stage, Germany once used military submarines to transport military materials, and started to design Store Carrier under water.Afterwards, the state such as Great Britain and America also studied and used nuclear carrier under water.Investigated construction Submarine Oilier, submarine ore-carrier, and other under water cargo ship possibility, its load carrying ability is 20,000-5 ten thousand tons.Under water ship military aspect application and to navigate by water at subglacial be very attractive, it can shorten the voyage through Chukchi Sea greatly.The transport of hiding is in wartime particular importance.

Under storm condition, the same speed of a ship or plane and load-carrying, under nuclear high speed water, oil tanker has obvious advantage relative to conventional oil tanker: what oil tanker loaded due to its freight house under water is liquid oil, it can not be compressed, when its navigation any degree of depth under water, the external and internal pressure total energy of its freight house keeps balance, and therefore its freight house housing can use non-withstand voltage structure.For the Submarine Oilier of identical tonnage, larger than the load carrying ability of pressure-resistance structure 30% of the non-pressure-resistance structure of freight house.In addition loading and unloading oils does not need to use any weight-lifting equipment, and oil can be loaded and unloaded by the aperture on hull and pipeline, and it is that Modern submarine is technically easy to accomplish that hull is opened aperture.But, up to now, in the world also without any the Submarine Oilier of practicality, more there is no Store Carrier.

Summary of the invention

The freight house that the present invention relates to carrier under water fills with air, and in cabin, the pressure of air enables freight house housing resist outside hydraulic pressure.It also makes the direction of net pressure suffered by freight house housing change into internal pressure by external pressure, and the internal pressure of this type of hull, the instability status of housing can be avoided, make cargo hold housing can become the non-pressure-resistance structure of single-layer metal.Such single hull, making underwater case to be opened large hatch becomes possibility, and the intensity caused thus and sealing problem also easily solve, and which overcome the difficulty of Modern submarine being loaded large-scale military equipment and goods.In addition, such arrangement effectively can reduce hull weight and increase cargo load, greatly reduces traffic cost.

It is a kind of cargo hold inflation dried food and nuts submarine of new structure, comprise pressure-resistance structure cabin and non-pressure-resistance structure cabin two class, the dry cargo hold of this submarine is the single-layer metal housing of non-pressure-resistance structure, and this dry cargo hold housing is provided with the hatch door of size dimension, in order to load and unload the dried food and nuts of full range of sizes; Its personnel compartment comprises work cabin, personnel's habitation module, commander compartment, control compartment, high pressure gas deposit cabin, personnel channel cabin and pressure conversion cabin, and they are the double-level-metal housing of pressure-resistance structure;

Personnel channel cabin and the pressure conversion cabin of pressure-resistance structure is provided with between the personnel compartment of pressure-resistance structure and the dry cargo hold of non-pressure-resistance structure, air pressure in pressure conversion cabin can regulate, so that personnel can change cabin turnover dry cargo hold eliminating accident by pressure when cargo hold has an accident;

Paste at cargo hold inwall and cover the airtight anti-gas-leak film of one deck, bulkhead gas leakage when navigating by water under water with hunter killer-craft dry cargo hold;

Opened door on the single-layer metal housing of the non-pressure-resistance structure of these submarine cargo holds, they are located at cargo hold bow respectively, bottom, top and sidepiece:

Arrange anticyclonic pressure deposit cabin in the cabin of pressure-resistance structure, settle air compressor, high-pressure gas bottle, or liquefied air tank, and the loading line and the charge valve that connect them, for filling with high pressure air to the dry cargo hold of submarine, to balance the hydraulic pressure of dry cargo hold outboard;

This kind of submarine is provided with the water surface discharge hoses road of umbilical, for a long time by the water surface supplied fresh air when making this kind of submarine under water, ensures that the normal running of diesel engine in ship and personnel breathe supply.

The various novel cargo submarine of inflation under water, engineering submarine and military submarines can be designed according to the principle of the invention, these submarines can load tank, battlebus, go straight up to or vertical-lift air-craft, deep submergence vehicle, middle-size and small-size submarine, guided missile, torpedo, dried food and nuts, bulk goods, freight container, be engaged in mine-laying under water, submarine supply, the piling of cloth cable stringing, Reconnaissance Survey, probing mining, salvage archaeology etc.It is multi-functional that they can be designed as a ship simultaneously.

Accompanying drawing explanation

Fig. 1 is the longitudinal profile schematic diagram of the dry cargo hold submarine of a cargo hold inflation.

This figure is divided into two parts I and II:

Part I I, its major part is made up of non-withstand voltage monoshell metal hull, comprises inflation dry cargo hold 4 and water tank 5; Only have minority be pressure structure personnel live and work chamber: comprise personnel channel cabin 7, commander compartment 8, pressure conversion cabin 9 and high-pressure air source store and control compartment 3.

Hatch 6a, 6b and 6c open the head at submarine respectively, bottom and top sidepiece, are used as to load and unload dried food and nuts from dry cargo hold 4.

Part II II, be all that personnel live and work cabin, it is made up of the common double-level-metal pressure-resistance structure of submarine.

Fig. 2 is the A--A viewgraph of cross-section on Fig. 1;

Fig. 3 is the B--B viewgraph of cross-section on Fig. 1;

Fig. 4 is the enlarged view of Fig. 3 cross section node 1.It is the hull of a non-withstand voltage single betal can shown in arrow 1; Arrow 2 is depicted as the airtight air-prevention that dry cargo hold inwall pastes and leaks film, prevents air from leaking due to cargo hold bulkhead.

Concrete embodiment:

Principle features of the present invention is that the dry cargo hold of submarine is filled with high pressure air.Like this when submarine under water time, the inboard of cargo hold and the pressure of outboard can be made to remain in same level (or both only have a little difference of pressure).The compressed air pressure of inboard balances the pressure of foreign water, just as Submarine Oilier by internal oil pressure support side of a ship outside hydraulic pressure principle.This inboard compression pressure that utilizes is called as " inflation top pressure principle " to the principle balancing foreign water pressure.

The principle features of the freight house inflation submarine that application " inflation top pressure principle " is invented and purposes comprise following some:

1) even the cargo hold of large-scale hull also can be frivolous non-pressure-resistance structure, just as Submarine Oilier.The weight of hull can be greatly reduced thus.Pressurized air is dry, does not almost have weight, it only occupy submarine carry full goods after idle space, therefore make the load coefficient of submarine greatly increase.

2) owing to keeping balance at the side of a ship internal gas pressure of hull cargo hold and outboard hydraulic pressure, hull housing does not need withstand voltage double hull, and it can be substituted by a non-withstand voltage single-layer metal housing.Like this, facilitate and open large hatch on this housing, large-sized military equipment and other goods are are easily loaded and unloaded by this kind of hatch at this submarine.Large hatch on this submarine has three kinds: at the bow of cargo hold, and bottom and top (side) portion, see hatch 6a, 6b and the 6c on Fig. 1 and Fig. 3.

Hatch 6a is located at the bow of submarine cargo hold, when submarine floats on the surface, for loader-unloader motor-car or motor device, as a large amount of amphibious landing tank, battlebus, logs in canoe, hovercraft and other civil cars, freight container and heavy rolling equipment etc.

Hatch 6b is the bottom being located at submarine cargo hold, the hatch door of this kind of hatch can be opened greatly about the same with the bottom area of whole submarine, because cabin internal gas pressure is identical with the hydraulic pressure of this degree of depth, even if large-area like this hatch door opens, seawater also can not enter in cargo hold.Can be implemented in operation snugly under water thus, bothering not by water surface storm.

Time under water from the bottom cargo hatch handling goods of submarine, water tank or directly in cargo hold water inlet can be allowed, reduce with the load-carrying after supplying dry cargo hold unloading, automatically regulate simultaneously and air pressure in stabilizing cabin to keep the diving depth of submarine constant;

According to this dry cargo hold feature, a series of military and engineering submarine can be designed, and they can a ship multipotency:

The function of military submarines comprises: 1, a large amount of der Amphibien-Tank, and amphibious assault vehicle and manned submarine or frogman log under water; 2, guided missile, easy the diving under water of torpedo is penetrated; 3, mine-laying under water; 4, become loading, release, reclaim the mother ship carrier of deep submergence vehicle and medium and small submarine; 5, the tender ship of the goods and materials under water of deep submergence vehicle and submarine, defense preparations, personnel;

The function of civilian submarine comprises: prospect under water, pipe laying, cloth cable, measures, piling, drilling well, physical prospecting, salvage, and archaeology waits series of new under-water operation engineering submarine.

Because the submerged depth of this kind of submarine is little, usually 40 meters of depth of waters, so the water surface discharge hoses road of available umbilical, for a long time by the water surface supplied fresh air when making this kind of submarine under water, ensure that the normal kinetic of diesel engine in ship and personnel breathe supply.And the disguise of underwater operation and not by sea storm impact advantage it can occupy.

Hatch 6c is out at the top of submarine cargo hold and sidepiece, when submarine floats on the surface, can be used to from dry cargo hold 4, load and unload bulk goods, dried food and nuts or equipment.Their handling can be undertaken by the hatch door on top or pipeline.The hatch door of side is also be handling motor device usually.The hatch door on top also can be gone straight up to or the outlet of lifting table of vertical-lift air-craft, so that the landing when submarine floats of this kind of aircraft.

3) although the pressure of the inboard of submarine cargo hold and outboard normally keeps balance, if needed, internal pressure can be greater than external pressure.Such arrangement is the fugitiveness of bearing external pressure in order to avoid cargo hold housing and producing.Thus, Hull Strength can improve, especially for the hull structure of large span shell.

4) cabin of inflating is conducive to keeping out into water.Meet when inflation cabin and damage, pressurized air can slow down cabin water inlet greatly.If infringement occurs in bottom cabin, no matter damaged part area has much, all cabin flooded condition can not occur.When cargo hold undamaged portion is when being greater than outboard hydraulic pressure at cabin inner air pressure, the gas leak-proof film being affixed on cabin inner walls can be used for the gas leak and the outboard water inlet that stop cargo hold undamaged portion.

The inflation technology and equipment of inflation submarine

The hull of dry cargo hold is the single hull structure of steel or other metals and the airtight leakproof film (see Fig. 4) of attached internal layer.Inflation pressure depends on the degree of depth of diving.Inflation pressure increases with the increase of the submarine diving degree of depth.The too large degree of depth, can challenge to equipment and safety.If but diving depth is too little, so adopt cargo hold inflation technology of the present invention just nonsensical.Therefore need to select the suitable degree of depth.Here by as follows for the inflation technique classification of inflation submarine:

1) once inflate at the water surface

This method, is that submarine floats over sea and carries out, when after Container Loading, is closed by cargo hold, is inflated by pipeline and charge valve with air compressor or high-pressure gas bottle or liquefied air tank to cargo hold.Inflation pressure should be equally large with the dive under water hydrostatic pressure of keel depth of expection.In submerge process, the degree of depth remains unchanged usually, and trickle keel depth changes the difference of pressure of inboard and the outboard caused, and can be born by the casing rigidity of cargo hold hull.When submarine is inflated across the sea, the internal gas pressure that cargo hold bears also oneself must be born by cargo hold housing.

The safeguards technique that inflation dried food and nuts submarine navigates by water in the little depth range of regulation is very simple.But this technology is only suitable in a little depth range.In general, desirable depth range is under water within the scope of 25 to 50 meters.By this method, the normal operation of diving depth to inflation dried food and nuts submarine of 40 meters is enough.Interference by ocean surface storm when this degree of depth is enough to avoid navigation of submarine (when naval vessel dive is under water to four times of hull diameters deep, can be disturbed from the water surface, thus also not produce wave making resistance.Accordingly, the cross-sectional plane out to out of general this kind of submarine can not more than 10 meters, so 40 meters of degree of depth are when meet this condition.) and keep the disguise of submarine navigation (submarine when 40 meters of depth of water, estimated cannot be seen by the aerial airman undergone training).In addition, the hull of steel is easy to bear 4 additional atmospheric internal pressures.

As long as usually fill the cargo hold of 40 meters of diving depths and just can reach equilibrium of pressure inside and outside the side of a ship with the pressurized airs of 4 additional pressures.This pressure is less than the air pressure that a motor tire fills usually.Crewman can directly enter inflation cabin by any special respirator.In the pressurized air of these 4 additional pressures, oxygen partial pressure is very low, and such environment can not cause burning because oxygen partial pressure is high.Meanwhile, we also can resist certain external pressure (as 4atm) by the steel hull of design, so the degree of depth of its diving also can more than 40 meters (namely the highest can reach 80 meters).Think the normal running navigation ensureing inflation submarine, 40 meters is suitable diving depths, and it also allows to use simple " inflation of water surface expression of first degree " technology.

2) inflate step by step under water

Should in this way, inflate step by step to cargo hold along with diving depth increases.The method is only for large diving depth and large hatch.

3) Mixing and aeration

This methods combining " is once inflated at the water surface " and " inflating step by step under water " technology.

When submarine is at the water surface, first inflate to cargo hold.Again along with the continuous dive of submarine, then increase gradually and inflate to cargo hold.Air compressor on the bank or high pressure empty bottle or liquefied air tank can be relied on when submarine is at the water surface to inflate to cargo hold, inflated to cargo hold by the pipeline of the charge valve and connection that are contained in cargo hold.In order to support to inflate to cargo hold 4 and pressure transition cabin 9 and be vented, the storage of a source of high pressure air and control cabin 3 are used for depositing and control anticyclonic pressure bottle and air compressor.The pressure of high-pressure gas bottle can reach 200-300atm, as long as cargo hold inflation pressure is not high, it is just easy to be provided as and stores the appropriate space needed for high-pressure air source equipment and weight, thus makes cargo hold can keep a suitable air pressure.

The inflation of cargo hold and exhaust process can be arranged on control pressurer system in cabin 3 to realize automatic control by one, and this system comprises various pressure sensor, valve, instrument, telltale and pipeline.Conventional submarine has air compression system, is mainly used in blowing down water inlet and supporting impaired cabin.The same cargo hold inflation used in the present invention of equipment in this air compression system and bleeding.

Inflate the structure of submarine, power plant and master layout

1) structure

The hull of whole inflation submarine adopts steel or other metal constructions.Pressurized module structure is used as crewman and lives and settle Power equipment and controlling equipment.In these cabins, air pressure maintains 1 barometric pressure all the time, to ensure normal life and the work of crewman.Non-pressure-resistance structure is only for cargo hold and water tank.The cargo hold of a shipping submarine will occupy most of volume of submarine.Cargo capacity is larger, and it is larger that the benefit brought inflated by cargo hold.It is reported, an A-tanker under water, its non-withstand voltage cargo component, compared with the pressure-resistance structure of identical tonnage, can cause cargo capacity to increase by 30%, reduce productive costs 50% simultaneously.For the hull weight of such oil tanker under water, estimate that by the surface ship than same load-carrying be little.Non-withstand voltage inflation cargo component of the present invention possesses above-mentioned identical advantage equally.

2) power plant

Inflation submarine has the power of two types: diesel engine/electric power and nuclear power source.With bavin/electrodynamic, battery charge must be allowed on sea, so diving depth should not be very large.In this case, inflation pressure is also little.When submarine is on sea, the pressure of cargo compartment will be born by its casing rigidity, and submarine can navigate by water within the scope of projected depth.For nuclear inflation submarine, because nuclear power source can navigate by water for a long time under water, the restriction of the keel depth not having power system to cause.

Because the submerged depth of this kind of submarine is little, usually 40 meters of depth of waters, so the water surface discharge hoses road of available umbilical, for a long time by the water surface supplied fresh air when making this kind of submarine under water, ensure that the normal running of diesel engine in ship and personnel breathe supply.This is suitable especially to the Engineering operation submarine of fixed-point type.And the disguise of underwater operation and not by sea storm impact advantage it can occupy.

3) master layout

Fig. 1 is the longitudinal sectional drawing of cargo hold inflation dried food and nuts submarine, and it is divided into two parts:

Part I, the metal single shell structure hull that most of right and wrong are withstand voltage, comprises inflation dry cargo hold 4 and water tank 5; Hull except the pressure structure of minority: comprise crewman corridor 7, commander compartment 8, pressure conversion cabin 9 and high-pressure air source storage cabin and maneuvering and control cabin 3.

Part II is all that they are all double-level-metal housing pressure structure by the normal pressure cabin of crewman there live and work.

Fig. 2 is the viewgraph of cross-section of A-A section in Fig. 1.

Fig. 3 is the viewgraph of cross-section of B-B section in Fig. 1.

The hull of non-pressure structure comprises inflation dry cargo hold 4 and water tank 5.These structures occupy the space of major part inflation submarine.Remaining personnel compartment, piggyback pod, control convenience cabin, commander compartment, corridor and pressure conversion cabin.These cabins are all places that crewman works and lives, and all should maintain 1 atmospheric pressure, cabin all uses the structure of pressure-resistant cabin.These structure major parts are the sterns (Part II of figure mono-) at inflation submarine.Crewman corridor 7 connects commander compartment and other berthing spaces.Observation window is located at both sides, crewman corridor, in the face of inflation cargo hold 4 and pressure transition cabin 9, is used as monitoring and safeguards.Air pressure in this pressure transition cabin 9 can change, and passes through wicket 10 and 11 pass in and out cargo hold (see Fig. 3) to allow crewman.Important pipeline, communication line and electric wiring are layed in corridor so that maintenance.Cargo door can be opened at submarine bow, bottom and upper (side) portion, and such layout is advantageous particularly to handling Large-Scale Equipment, as tank, guided missile, aircraft, deep submergence vehicle, torpedo, submarine mine, and vehicle, freight container and other equipment.

The safety of inflation cargo hold

1) inflate safely and be vented, preventing gas leakage

When submarine is inflated across the sea, the leakage of gas should be prevented.The pressure that the autocontrol valve be connected when inflating under water gradually, with sensor should be used to control to inflate cabin increases (inflation) and reduces (exhaust).Submarine dive deeply be less than 100 meters of degree of depth time, fill with air to cargo hold; Dive deeply be greater than 100 meters of degree of depth time, in cabin, oxygen partial pressure can increase due to the corresponding increase of cabin compressed air pressure.To prevent cargo hold oxygen partial pressure high, easily cause burning.For preventing the goods in dry cargo hold to be easy to burning because oxygen partial pressure is too high, at least must fill when inflating to cargo hold with part oxygen free air or other non-flammable compressive gases; Suitable oxygenless gas comprises oxygen free air, nitrogen and carbon dioxide.In this environment, personnel enter these high pressure cargo hold cabins and must wear breathing apparatus.

First inflation cargo hold usually needed decompression before unloading.The simplest method is that cargo hold passes through to be vented under water or to realize decompression in the method for water surface exhaust.The operation of decompression exhaust needs controlledly to be exhausted through blow off valve, in order to avoid injury and damage equipment.

The inflation cargo hold of inflation submarine does not allow under water air leakage to occur, because such gas leakage can reduce the intensity of air leak position hull, causes the accident or exposes submarine position hidden under water at durante bello.When the internal pressure of cargo hold is greater than side of a ship external pressure (namely navigating by water in the little degree of depth), gas leakage under water usually occurs in hull and connects and other aperture places.For preventing gas leakage from occurring, spread at the inwall of cargo hold and cargo holds with the close film of anti-gas-leak, its function is just as the inner tube of a tyre of motor tire.

2) monitored control system

The usual live and work of crewman of cargo hold inflation submarine in the atmospheric chamber of a bar pressure (1atm), and does not go in high pressure cargo hold.Therefore, in atmospheric chamber, a monitored control system can be installed usually, in order to monitor cargo hold.Monitored control system can be used for monitoring the generation of cargo hold accident, comprises fire, water leaks and air leakage.Monitored control system comprises observation window, sensor, closed circuit television equipment and communicate/command echelon etc.

3) prevent fires

When inflating navigation of submarine 40 meters of depth of water degree of depth, cargo hold need add the air filling 4 additional pressures.In this case, the oxygen partial pressure in cargo hold is lower than 1atm.Oxygen partial pressure does not although it is so allow fire hazardous, but still needs to follow certain security procedure to inflation cargo hold, should take measures to prevent the burning of hold cargo.All need to arrange extinguishing equipment at cargo compartment and outside.If what fill in cargo hold is non-oxidising gas, fire prevention is not just a problem.

4) goods demand

In inflation cargo hold, the goods of all loadings must can bear the pressure in inflation cabin.This requires general dried food and nuts and bulk goods is all no problem usually.But to industry and military equipment, all by voltage-withstand test, all should compression test be done.Some also needs to take some preparation measures to goods, comprises and need add withstand voltage protecting sleeve to non-withstand voltage instrument and will fill it up with fuel etc. to engine fuel case before inflation.

Crewman is in the safety in anticyclonic pressure cabin

At ordinary times when navigation of submarine, crewman all stays in the atmospheric chamber of a barometric pressure (1atm), only has when the cargo hold Shi Caihui that has an accident enters cargo hold.Personnel enter the problem of cargo hold hyperbaric environment by therefore facing.Need when crewman enters and exit cargo hold to carry out according to hyperbaric diving table medical safety program.Crewman should complete diving training.Only have through diving training, crewman could carry out safe in operation in the hyperbaric environment in inflation cabin.When crewman exits high pressure cargo hold, decompression program must be followed equally.A pressure conversion cabin is located at and is positioned between normal ambient pressure cabin (atmospheric chamber) and high-pressure aerated cabin.People per minute 4 atmospheric speed can enter a hyperbaric environment usually.So personnel can enter anticyclonic pressure cargo hold by atmospheric chamber soon.

When submarine is when the depth of water is the degree of depth of 40 meters, pressure in inflation cargo hold is 4 additional pressures (ading up to 5 barometric pressures), now crewman can stop 24 hours safely in such a case, can directly breathe air in cabin, and need not wear breather mask.So just ensure that crewman has time enough handling failure and problem in anticyclonic pressure cargo hold.

Personnel must be reduced pressure when leaving cargo hold, occur to prevent decompression sickness.Decompression need be changed in cabin at pressure and carry out.Decompression time depends on the pressure of cargo hold, and personnel are exposed on anticyclonic time length, the type of breathing gas when cargo hold.Usual personnel only need within 10 to 20 minutes, to carry out the trouble in handle high voltages cabin, can use rapid decompression technology like this, and it only needs a few minutes can complete the decompression program of personnel.For guarantee safety, personnel strictly should follow suitable decompress(ion) program.

When diving depth is more than 60 meters, the air pressure in cargo hold can more than 7atm.Personnel just directly can not breathe pressurized air under air pressure high like this, now should breathe helium oxygen or nitrogen oxygen mixed gas with breathing apparatus.Decompression time also will than during above-mentioned comparatively lower hold pressure for long.The current mankind can breathe helium oxygen compound and reach 61 barometric pressures, and this is equivalent to the hydraulic pressure when 600 meters of depth of water.As can be seen here, operating personal can stop and operate under very high air pressure environment.
