Description
Technical field
But the present invention relates to a kind of semi-submersion type self deepening boat from low speed partially surfaced condition floating upward quickly when navigating by water at a high speed.
Background technology
In existing technology, ships and light boats are divided into water surface ships and light boats and ships and light boats two big classes under water in its navigation mode in water.Ships and light boats are to change its weight after submarine is annotated draining by set ballast chamber under water, and the reserve buoyance of elimination or recovery ship is dived floating.During dive, adopt dump injection; During come-up, adopt high pressure air or mechanical pump draining.This drainage pattern often needs a large amount of high pressure airs or high-performance kinetic pump.Particularly during the dynamic floating upward quickly of ships and light boats, all the more so.Adopt this mode that deepens, the manufacturing cost height of the structure of ships and light boats and system complex, security requirement height, ships and light boats not only, and use and operate also very complicated.Water surface ships and light boats swim on the water surface and navigate by water, and use operation comparatively convenient, but when having navigation a little less than the wind-proof and wave-proof performance, disguised poor, freeboard depth is than problems such as height.
Summary of the invention
Technical matters to be solved by this invention is the deficiency that exists at above-mentioned prior art and a kind of semi-submersion type self deepening boat is provided, and it is not only simple in structure, and it is floating quick to dive, and uses easy to operately, and the wind-proof and wave-proof performance is strong, good concealment during awash run.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is:
Include hull 2 and be arranged on the ship propulsion system 6 of afterbody, be provided with sealing or semi-enclosed superstructure above the hull, in the bilateral symmetry of hull vertical ballast chamber 1 is set, vertically the afterbody opening 4 of ballast chamber communicates with the external world; Described vertical ballast chamber is the runner shape, and runner is that preceding high back is low; Its difference is that afterbody opening 4 places of vertical ballast chamber are installed on able to turn on or off watertight hatchcover 5; Vertically ballast chamber extends to the ship stern from stem, establish bow ballast chamber 3 in the hull stem, and communicate with vertical ballast chamber 1 of both sides, be installed on breather pipe 7 above the bow ballast chamber, install sea valve or opening at the lowest part of bow ballast chamber, and corresponding configuration clap board alow, so that hull bottom forms negative pressure.
Press such scheme, the runner of described vertical ballast chamber can be linearity or curve-like.
Press such scheme, also hull bottom ballast chamber longitudinally can be set in the bottom of hull, the afterbody opening of hull bottom ballast chamber communicates with the external world.
Press such scheme, the afterbody opening part of ballast chamber is installed on able to turn on or off watertight hatchcover alow.
The present invention half dives and the dominant mechanism of come-up state navigation is: when ships and light boats when berthing and navigate by water at a slow speed, water injects the ballast chamber of hull both sides and hull bottom by afterbody opening (the opening the watertight hatchcover) gravity flow of ballast chamber.Ships and light boats weight is increased, eliminate the reserve buoyance of ships and light boats, can make the ships and light boats dive, to hull, flush, only expose the part of deck or superstructure, enter partially surfaced condition with the water surface.When ships and light boats were done to quicken navigation under dynamic action, extraneous water and ballast water formed difference of pressure, and ships and light boats make ballast water form back stream under effect of inertia, and the ships and light boats bow slightly lifts; The negative pressure that stern forms produces adsorption to ballast water; Favourable stern inclines and makes the hull dynamic lift rise, and causes ballast water all to be discharged voluntarily fast with the speed of a ship or plane increase of ships and light boats and from stern; The weight saving of ships and light boats, the reserve buoyance of ships and light boats is recovered, the purpose that reaches the ships and light boats come-up and navigate by water at a high speed.The come-up of ships and light boats helps reducing running resistance, further improves the speed of a ship or plane of ships and light boats.In addition, navigate by water at a high speed after ballast water all discharges voluntarily from stern, close the watertight hatchcover of opening part, ships and light boats are bubbled through the water column at reduction of speed with when berthing at ships and light boats.
Beneficial effect of the present invention is: 1, ships and light boats are simple in structure, need not increase extra last floating apparatus and power, low cost of manufacture, and safety performance height; 2, arrange the notes ballast chamber by the speed of a ship or plane that changes ships and light boats, reach the quick conversion of the latent floating state of ships and light boats, such dynamic translation is effective and rapid, uses operation also very convenient; 3, during partially surfaced condition, the wind-proof and wave-proof performance of ships and light boats is strong, good concealment during navigation; Be mainly used in ships and light boats when berthing, need to reduce the above ships and light boats shape of the water surface, need to reduce the ships and light boats of special purpose such as freeboard, as the quick ships and light boats of stealthy requirement, the quick rescue ship of low freeboard etc.

The specific embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.Include hull 2, at afterbody ship propulsion system 6 is set, bilateral symmetry at hull is provided with vertical ballast chamber 1, the afterbody opening 4 of ballast chamber communicates with the external world, afterbody opening 4 places at described vertical ballast chamber 1 are provided with able to turn on or off watertight hatchcover 5, be made of a telescopic lever and a side pivotally attached watertight hatchcover 5, the rotation that can make progress of watertight hatchcover is opened; Vertically ballast chamber 1 is the runner shape, and runner is that preceding high back is low, so that ballast water flows out from afterbody opening 4.In order to make ships and light boats after the dive keep relative flat floating, establish bow ballast chamber 3 in the hull stem, and communicate with vertical ballast chamber 1 of both sides, be installed on breather pipe 7 above the bow ballast chamber 3.During come-up, the water of bow ballast chamber 3 flows out together along the runner of vertical ballast chamber 1; Lowest part at bow ballast chamber 3 can be installed sea valve or opening, and corresponding configuration clap board alow, so that hull bottom forms negative pressure.The water that is lower than vertical ballast chamber 1 runner can flow out outside the ships and light boats by being located at the minimum sea valve of bow ballast chamber 3 or the opening of hull.When ships and light boats float in the water, because of the lowest part of vertical ballast chamber 1 afterbody opening 4 underwater, extraneous water can flow in the ballast chamber 1 automatically.Because weight increases gradually, ships and light boats begin to sink, and the degree of depth that ships and light boats sink is directly proportional with the stowage of runner.The size of ballast chamber will be in conjunction with institute dive height and the floading condition after diving determine.Usually the ballast water yield of ballast chamber is the 50-150% of ships and light boats self displacement, and example: a marine railway water yield is 300 tons, needs the half latent freeboard limit of arriving.By calculating, the weight that increases by 200 tons just can make drinking water increase to the freeboard place, therefore needs to establish in ship＞200m
3The volume of runner; Need half latent certain (the superstructure domestic demand is established the part buoyancy compartment) to superstructure, by calculating, the weight that increases by 380 tons just makes drinking water increase to superstructure certain, therefore needs to establish in ship＞380m
3The volume of runner.Ships and light boats need float when navigating by water at a high speed, and ship is made accelerated movement.At this moment, vertically the ballast chamber 1 interior water water that carries begins to flow into the external world automatically from stern opening 4.Along with water in the ballast chamber reduces, the speeding up of ships and light boats, the water in the runner can all be discharged.When ships and light boats are made decelerated movement, after intaking, stern opening lowest part flows in vertical ballast chamber 1 automatically again, make in ships and light boats sinking half latent the swimming.Vertically ballast chamber 1 is arranged on hull both sides or hull midship line face, presses the arrangement requirement of ships and light boats and determines that vertical ballast chamber of each side can be provided with 1-2.The tail end side of the being stern structure of hull, ships and light boats will have the higher speed of a ship or plane (displacement Fo Shi counts Fr Δ＞1.6).Be that the bottom of ships and light boats stern end is under the effect of speed and slides shape, it is extraneous that runner water is flowed into.
