Abstract
The invention belongs to a kind of fast speed buoyancy anti-sink device for submarines, form by gas generator [1], quickly cooling device [2] and rubber pocket [3].Principle of work is: solid gunpowder is lighted automatically during submarine accident, and combustion gas is full of leather bag [3] through over cooling, produces buoyancy, makes the submarine come-up.Characteristics of the present invention are: 1 buoyancy that provides is extra, and unrestricted.2 separate with high-pressure system, can not produce the detonation problem.3 device volumes are little, and are easy and simple to handle, and any model submarine all can use.
Description
The invention belongs to a kind of fast speed buoyancy anti-sink device for submarines.
At present, submarine to stock buoyancy more and more littler, and the volume of each subdivision is increasing in the pressure-resistant cabin.If the pneumatic shell damage and water inflow causes submarine accident, then submarine just can't float voluntarily, causes people's ship of dying heavy.In order to strengthen the survivability of submarine self, the various countries expert proposed various schemes, and attempt addresses this problem.The U.S. carries out the research of " he rescues " for this reason specially.Develop deep submersible rescue vehicle (DSRV).The Soviet Union and France have carried out the test that utilizes the solid gunpowder combustion gas that ballast chamber is blown down fast, but because of containing H in the combustion gas
2With fire gases such as CO, be mixed with the danger that produces blast with high pressure air, the ballast chamber volume is limited in addition, still can't resolve problem.West Germany then adopts the hydrazine air-blowing to remove, and also is to blow down fast to ballast chamber, still can't resolve the problem that increases buoyancy.And hydrazine is poisonous, should not store on ship for a long time.In addition, also studied " escape ball " abroad and rescued the method that the people abandons ship, if but do not have an accident, submarine is just being loaded with a useless at ordinary times spheroid forever.
The present invention is exactly a kind of submarine self-saving fast speed buoyancy anti-sink device that proposes at above-mentioned existing problems.Its principle of work is: during the submarine pressure hull damage and water inflow, the solid fuel in the container (or artificial) is automatically lighted, and the gas that burning produces is inflated to rubber pocket, makes it to produce buoyancy, makes the wrecking submarine come-up.The present invention has following characteristics: 1. the buoyancy that is provided is extra, and unrestricted.2. separate with high pressure air system, can not produce the detonation problem.3. device volume is little, and is easy and simple to handle, and irrelevant with the submarine self character, promptly any submarine all can adopt this device.
The present invention mainly is made up of gas generator (1), quickly cooling device (2) and rubber pocket (3).Wherein gas generator (1) comprises housing (4), grate (5), electric firing cap (6), the cartridge bag that ignites (7), nozzle (8), moistureproof diaphragm (9) and seal ring (15).Quickly cooling device (2) is made up of conduit (10), separation rubber diaphragm (11) and conduit (12).Between nozzle (8) and the leather bag (3) a connector (13) is arranged.In order to make leather bag external and internal pressure difference is that safety valve (14) is housed on a homogeneous, the leather bag, regulates the inside and outside differential pressure size, and constant buoyancy is provided.
After submarine damaged cabin water inlet, (or manual control) connects electric firing cap (6) under autoalarm control, lights the cartridge bag that ignites (7), makes the pressure in the powder burning chamber of gas generator (1) reach 30 kilograms per centimeter
2More than, and the solid gunpowder that ignites rapidly.This solid gunpowder adopts the double-basis solid gunpowder; Ignition powder adopts black powder.Under the control of area of injection orifice, the solid gunpowder burning can produce the 70-90 kilograms per centimeter
2The combustion gas of pressure sprays from spout.The pressure at spout place identical with ambient pressure (relevant) with the degree of depth of submarine accident.Under the difference of pressure of conduit (10) and conduit (12), cooling water expansion tank passes through conduit (12) with the 40-60 kilograms per centimeter
2Pressure is ejection around spout, makes combustion gas be cooled to the temperature that rubber can bear rapidly.After playing 4.5 seconds during spontaneous ignition, rubber pocket is inflated rapidly, and certain buoyancy is provided immediately.After the buoyancy of submarine was greater than gravity, ship began come-up.Pressure in ten meters of every come-ups, the ambient pressure barometric pressure that will descend, rubber pocket increases, thereby the leather bag volume increases.When greatly to a certain limit, safety valve (14) self-opening, outwards unnecessary combustion gas is put in the pond.
Claims (7)
