Abstract

The utility model relates to a multi-functional air-bag shell of underwater vehicles, is mainly used for underwater vehicles, and belongs to the field of ships and warships. Shell steel plates of an underwater vehicle are wrapped with a plurality of blocked air bags, and each air bag is provided with a breather pipe (4) and an air port (3). When the underwater vehicle needs to sink, the air bag is deflated; when the underwater vehicle needs to float, the air bag is inflated; and accordingly the movements of sinking and floating are completed. Simultaneously, the air bag can buffer impact force of the shell steel plates when the underwater vehicle is crashed, thereby protecting the shell steel plates of the underwater vehicle. In addition, inflating quantity and exhausting quantity can be controlled by a computer, the appearance of the vehicle body can be controlled locally, and fast upwarp and fast sinking of a vehicle prow can be achieved. Simultaneously, the air bag can enable the appearance of the vehicle body to be in a shape of a plurality of convex surfaces and concave surfaces, and accordingly water resistance of turbulent flow is reduced and sailing speed is increased. The underwater vehicle is wrapped by the air bag, thereby reducing noise made by a propulsion system of the underwater vehicle, reducing reflected waves of enemy warship sonar and enabling the underwater vehicle not easy to be found by the enemy warship.

Description

Multi-functional submarine navigation device air bag shell

Technical field

The utility model is mainly used in submarine navigation device, belongs to the field, naval vessel.

Background technology

All finish by Ballast Tank inflation, exhaust when the submarine navigation device that China uses at present need float or sink, Ballast Tank has occupied the available space of aircraft preciousness; In addition, the shell of submarine navigation device all adopts outer cover of steel plate, collision or hit easily when stranded and split steel plate and the shipwreck disaster takes place, and outer cover of steel plate is also found by the enemy warship sonar easily.

Summary of the invention

The utility model has overcome the problems referred to above, it is an air bag of the shell steel plate of submarine navigation device being wrapped a plurality of piecemeals, each air bag all is furnished with breather pipe (4) and vent (3), when need sinking, gives submarine navigation device air bags, give airbag aeration when needing come-up, thereby finish and the come-up action.Simultaneously, the impulsive force of ship outer casing steel plate when air bag can also cushion the aircraft collision, protection aircraft shell steel plate.In addition, can also control the filling of each air bag, free air capacity,, finish the action that fore upwarps rapidly and sink rapidly from part control hull lines by computer.Simultaneously, the air bag of a plurality of inflations or exhaust also can form hull lines a plurality of convex or concave shape, can reduce the turbulent drag of water like this, accelerates aircraft or route speed waterborne under water; Because the parcel of air bag, submarine navigation device can reduce the noise that its propulsion system spreads out of; The air bag made from rubber can also reduce the backward wave of enemy warship sonar, makes submarine navigation device be difficult for being found by enemy warship.

The utility model is wrapped in the air bag shell of forming navigation on the outer cover of steel plate of submarine navigation device by a plurality of air bags; Each air bag is made into single integral gasbag and is furnished with vent (3) and breather pipe (4) by gasbag chamber (1), air bag sidewall (2), air bag antetheca (5), air bag frame (7), air bag base plate (8).

Five, the specific embodiment

Below in conjunction with description of drawings principle of work of the present utility model.

Referring to Fig. 1, Fig. 5, the air bag of a plurality of piecemeals is wrapped on the shell steel plate of submarine navigation device.Referring to Fig. 2, Fig. 3, each air bag all is furnished with breather pipe (4) and vent (3), when hull need float, give gasbag chamber (1) inflation by breather pipe (4) by vent (3), gasbag chamber (1) is full of the volume that will arrange water behind the gas, the hull come-up, when hull need sink, give gasbag chamber (1) exhaust by breather pipe (4) by vent (3), gasbag chamber (1) is in the pressure lower compression of water, the hull cumulative volume reduces, and hull sinks; In addition, if the breather pipe of each air bag is all joined solenoid electric valve, the unlatching of valve is closed by computer control, and the filling of each air bag, free air capacity when the hull fore partly needs to float rapidly, can be given fore part airbag aeration with regard to may command; Stern part air bags, fore can upwarp rapidly.Otherwise, when the hull fore partly needs to sink rapidly, can give fore part air bags; Stern part airbag aeration, fore can sink rapidly.By Fig. 2, Fig. 3 as can be seen, air bag sidewall (2) one-tenth rugosity and thickness are all thinner, and air bag sidewall (2) can stretch when inflation, exhaust preferably like this; The thickness of air bag antetheca (5) is also thinner, so air bag antetheca (5) so just can reduce the turbulent drag of hull generation when navigating by water preferably in inflation, can form convexity and spill preferably during exhaust.Air bag frame (7) is more abundant, can guarantee that like this profile of single air bag is indeformable, guarantees that simultaneously interface is level and smooth between air bag and the air bag, reduces the resistance of water.
