Abstract
A ship body of a submarine has a vacuum structure; the vacuum structure is characterized in that a layer of vacuum steel plate (2) is additionally arranged on a ship body shell (1); a certain gap exists between the vacuum layer steel plate (2) and the ship body shell (1); the gap is vacuumized to form a vacuum layer (3), so the noise generated by various machines is only transmitted to the vacuum layer steel plate (2); due to the arrangement of the vacuum layer (3) between the vacuum layer steel plate (2) and the ship body shell (1), the noise on the vacuum layer steel plate (2) cannot be transmitted to the ship body shell (1) of the submarine, so that the noise of the submarine is reduced.
Description
Technical field
The invention belongs to hull and manufacture field, specially refer to the hull of Submarine.
Background technology
Conventional submarine and atomic submarine are radiated the noise in water, are a kind of noises that the disguise of submarine itself is constituted a serious threat.Therefore, reducing submarine noise is the gordian technique of improving its combat capabilities.
The noise of conventional submarine and atomic submarine has three sources, and the one, by the running of the various mechanical equipments of Method for Inside Submarine's, vibration, friction, the major cycle water pump of the reducing gearbox of main frame and reactor etc.But the vibration of its various device and the noise of running are to pass to hull by the pedestal of equipment and air and other members, thereby cause the vibration of hull shell, and are radiated in water.The 2nd, screw propeller when rotation vibration, bounce current and the noise that produces; The 3rd, in the time of submarine movement, hull impacts the turbulent flow that causes of current and the hydrodynamic noise that produces.
At present, the measure of main noise-decreasing has: dress boat equipment adopts damping support or damping buoyant raft, adopts low noise screw propeller, development is used pump injecting type propelling unit that noise is less and the natural-circulation capacity (object is to cancel the noise of major cycle water pump) of mhd propulsion system, raising nuclear power plant, use electric propulsion (in order to eliminate this Main Noise Sources of reducing gear in steam propulsion mode) etc., but its effect is undesirable, the Submarine of China is in the technical U.S. and the Russia of lagging behind of noise.
To sum up state conclusion, no matter be contained in the equipment of submarine the inside, its noise and vibration is all sat or be sent on hull shell by the air in submarine bin by the machine of machinery and equipment, thereby causes that hull shell and then vibrates and generation noise.
Object of the present invention is just to provide a kind of vacuum hull, make the noise of the machinery and equipment in bin cannot pass to submarine hull shell, reduce the noise of submarine, strengthen the disguise of submarine itself, and improve the pressure resistance of hull, also actv. has prevented the impact of sea temperature on Method for Inside Submarine's, thereby has improved the fighting capacity of China's submarine.
Summary of the invention
In order to achieve the above object, the technical scheme that the present invention takes is: it has vacuum structure a kind of hull of submarine; It has hull shell, vacuum steel plate, and vacuum layer, evacuating valve, and connecting material forms.Described vacuum layer is on hull, to add one deck vacuum layer steel plate again, between described vacuum layer steel plate and hull shell, has certain gap, is evacuated and forms vacuum layer between this gap, and this noise that various machines are produced can only be sent to vacuum layer steel plate.Between vacuum layer steel plate and hull shell, owing to there being the relation of vacuum layer, the noise on vacuum layer steel plate cannot be passed on the hull shell of submarine, thereby reduced the noise of submarine.Between described vacuum layer steel plate and hull shell, fix and be connected with the good material of sound insulation vibration isolating effect.In order to prevent that the degree of vacuum of vacuum layer and the leakage of vacuum are being divided into several vacuum layer regions on the hull of submarine, evacuating valve is installed in each region, vacuum indicator, and place getter MAT'L.
Brief description of the drawings
Fig. 1 is the front view of a kind of Submarine hull of the present invention shell.
Fig. 2 is the A-A cutaway view of a kind of Submarine hull of the present invention shell
Structure shown in figure comprises: ship outer casing (1), vacuum layer steel plate (2), vacuum layer (3), connecting material (4), getter MAT'L (5), vacuum indicator (6), evacuating valve (7)
Specific embodiments
By reference to the accompanying drawings 1, accompanying drawing 2 is described further the embodiment of the present invention:
A kind of hull of Submarine has vacuum structure, its vacuum structure by: on ship outer casing (1), add again one deck vacuum layer steel plate (2), between described vacuum layer steel plate (2) and hull shell (1), there is certain gap, between this gap, be evacuated and form vacuum layer (3), the noise that various machines are produced can only be sent to vacuum layer steel plate (2), between vacuum layer steel plate (2) and hull shell (1) owing to there being the relation of vacuum layer (3), noise on vacuum layer steel plate (2) cannot be passed on the hull shell (1) of submarine, thereby reduce the noise of submarine.Between described vacuum layer steel plate (2) and hull shell (1), fix and be connected by the good connecting material of sound insulation vibration isolating effect (4).For the degree of vacuum that prevents vacuum layer (3) declines, being divided into several vacuum layer (3) region on the hull shell (1) of submarine, each region is installed evacuating valve (7) vacuum indicator (6) and is placed getter MAT'L (5).
Claims (2)
- A Submarine hull its formed by ship outer casing (1), vacuum layer steel plate (2), vacuum layer (3), connecting material (4), getter MAT'L (5), vacuum indicator (6), evacuating valve (7); It is characterized in that: on ship outer casing (1), add again one deck vacuum layer steel plate (2), between described vacuum layer steel plate (2) and hull shell (1), there is certain gap, between this gap, be evacuated and form vacuum layer (3), between described vacuum layer steel plate (2) and hull shell (1), fix and be connected by the good connecting material of sound insulation vibration isolating effect (4).
- 2. according to a kind of Submarine hull described in claim 1, it is characterized in that: on the hull shell (1) of submarine, be divided into several vacuum layer (3) region, each region is placed getter MAT'L (5) and vacuum indicator (6) evacuating valve (7) is installed.
