Above-mentioned all temps, pressure, electromagnetic force, vibration, the concrete structure of humidity gauge tap or control reference parameter are as follows, but do not place restrictions in the parameter that provides below, as long as floatable black box is in air or the difference value of the environmental baseline parameter that provides in normal condition of the environmental baseline parameter that obtains in seawater and aircraft, but can be as the switch controlled variable of these openable container 5 switches 6.

1, the temperature detect switch (TDS) of low temperature: described to be subjected to temperature controlled switch 6 being less than or equal to-10.0 ℃ of states be the hermetically closing state, and at aircraft just often, aircraft is less than or equal to-10.0 ℃ of environment for floatable black box provides.Aircraft accidents happened the back floatable black box leave aircraft, on the sea, the water surface is higher than-10.0 ℃ of states, switch 6 is the conducting opening, but different gasifiable thing in two or more openable containers 5 or pressure gas 4 all enter in the sealed soft bag 2 and mix, produce chemical reaction, produce the very little gas of a large amount of gases or density, make sealed soft bag 2 gassies or low density gas, become balloon body and produce buoyancy.

2, the temperature detect switch (TDS) of high temperature: or the temperature detect switch (TDS) 6 of described high temperature is the hermetically closing state being higher than 50.0 ℃ of (＞50.0 degrees centigrade) states, and at aircraft just often, aircraft is higher than 50.0 ℃ of environment for floatable black box provides to be less than or equal to.Aircraft accidents happened the back floatable black box leave aircraft, on the sea, the water surface is less than or equal to 50.0 ℃ of (≤50.0 degrees centigrade) states, switch 6 is the conducting opening, but different gasifiable thing in two or more openable containers 5 or pressure gas 4 all enter in the sealed soft bag 2 and mix, produce chemical reaction, produce the very little gas of a large amount of gases or density, make sealed soft bag 2 become balloon body and produce buoyancy.

3, dual pressure control switch: the described switch 6 that controlled by static pressure is the hermetically closing state greater than 1.5 atmospheric pressure states the time, and at aircraft just often, aircraft provides greater than 1.5 atmospheric pressure hyperbaric environments for floatable black box.Aircraft accidents happened the back floatable black box leave aircraft, on the sea, the water surface is less than or equal to 1.5 atmospheric pressure, switch 6 is the conducting opening, but different gasifiable thing in two or more openable containers 5 or pressure gas 4 all enter in the sealed soft bag 2 and mix, produce chemical reaction, produce the very little gas of a large amount of gases or density, make sealed soft bag 2 become balloon body and produce buoyancy.Utilization is left two kinds of environment of aircraft in the aircraft neutralization, but the pressure difference that floatable black box is subjected to is technical essentials of this switch as switch 6 controlling elements of openable container 5, for this reason also can be just often with aircraft, provide greater than 5.0-3.0 atmospheric pressure hyperbaric environment, when aircraft after floatable black box leaves aircraft and enters sea, the water surface fast after accidents happened, as long as environment in less than the water of 3.0 atmospheric pressure pressure, but the switch 6 of openable container 5 can be opened and emits gasifiable thing or pressure gas 4 enters sealed soft bag 2.

4, electromagnetic force gauge tap: the switch 6 of described electromagnetic force control has the sheet metal that two or polylith can be subjected to magnetic attraction; But two of switch 6 usefulness of openable container 5 or the polylith sheet metal sealed open that can be subjected to magnetic attraction exactly.At aircraft just often, aircraft can be subjected to the sheet metal of magnetic attraction to attract sealing two or polylith to floatable black box with electromagnet.Aircraft accidents happened the back floatable black box leave aircraft, on the sea, the water surface do not have electromagnet to attract sheet metal, two or the separation of polylith piece sheet metal, switch 6 is the conducting opening, but different gasifiable thing in two or more openable containers 5 or pressure gas 4 all enter in the sealed soft bag 2 and mix, produce chemical reaction, produce the very little gas of a large amount of gases or density, make sealed soft bag 2 become balloon body and produce buoyancy.

5, vibration force gauge tap: the switch 6 of described vibration force control is that black box 1 is subjected to the switch that the conducting of vibration force ability is opened more than 30 kilograms, and it is to keep the hermetically closing state of switch that black box 1 is subjected to 30 kilograms of following vibration forces.At aircraft just often, the aircraft vibration can not be higher than 30 kilograms of vibration forces, accidents happened that the back floatable black box leaves that aircraft drops into the sea for aircraft, instantaneous in the water, can both produce greater than 30 kilograms of vibration forces makes switch 6 be the conducting opening, but different gasifiable thing in two or more openable containers 5 or pressure gas 4 all enter in the sealed soft bag 2 and mix, produce chemical reaction, produce the very little gas of a large amount of gases or density, make sealed soft bag 2 become balloon body and produce buoyancy.Local oscillator power control switch also can be according to the parameter of the concrete maximum vibration power scope of aircraft as switch 6 air-tight states, and use greater than the normal maximum vibration power of aircraft range parameter as the vibration force parameter of opening switch 6.The parameter of gauge tap 6 is not placed restrictions in 30 kilograms of vibration forces, can determine the parameter of vibration force gauge tap 6 according to different aircraft normal vibration strength separately.

6, the switch of humidity control; The switch 15 of humidity control be with switch 15 that the control of water or anhydrous immersion humidity is arranged as controlled variable, when when humidity sensor 17 is in anhydrous soaking state, aircraft is to be in normal condition, humidity sensor 17 makes switch valve 16 be the hermetically closing state.Have an accident and work as aircraft, floatable black box fall into the water ((in seawater)), the humidity sensor 17 of sealed soft bag 2 outsides is in when water logging blister attitude is arranged, humidity sensor 17 sends and refers to that the present makes switch valve 16 be the conducting opening, but different gasifiable thing in two or more openable containers 5 or pressure gas 4 all enter in the sealed soft bag 2 and mix, produce chemical reaction, produce the very little gas of a large amount of gases or density, make sealed soft bag 2 gassies or low density gas, become balloon body and produce buoyancy.

Chemical reaction takes place, the gasifiable thing or the pressure gas material of the floatable black box of imitative flame snuffer principle: gasifiable thing or pressure gas 4 are aluminium sulphate and sodium bicarbonate solution, but aluminium sulphate and sodium bicarbonate solution are contained in respectively in two openable containers 5, sealed soft bag 2 also can be put some gas-development agents, as Radix Glycyrrhizae or Chinese honey locust etc.At aircraft just often, aluminium sulphate does not contact mutually with the sodium bicarbonate solution material, and any chemical reaction does not take place.Accidents happened that the back floatable black box leaves that aircraft drops into the sea for aircraft, in the water after, but the switch 6 of these two openable containers 5 is all opened, aluminium sulphate and sodium bicarbonate solution all enter sealed soft bag 2 to be mixed, and produces a large amount of carbon dioxides, makes sealed soft bag 2 become balloon body and produces buoyancy.Except that the combination of aluminium sulphate and sodium bicarbonate solution generation gas, before other two or more chemicals reactions is solid or liquid or pressure gas, produce the complex of the very little gas of a large amount of gases or density after the reaction, all can be used for the gasifiable thing or the pressure gas material of the floatable black box of imitative flame snuffer principle.

Chemical reaction takes place, imitative flame snuffer principle, but the floatable black box that two or more openable container swing crushings are opened: gasifiable thing or pressure gas 4 are contained among the rapid wear container 10, and rapid wear container 10 and black box 1 independently are positioned among the sealed soft bag 2 respectively.Rapid wear container 10 is meant at aircraft and just often is difficult for damaging, aircraft accidents happened the back very big vibration force that provided intentionally of floatable black box, or leave aircraft and drop into the sea, instantaneous in the water, spontaneous very big vibration force and make 10 fragmentations of rapid wear container, gasifiable thing or pressure gas 4 in the rapid wear container 10 enter sealed soft bag 2, solid in two or more rapid wear containers 10 or the gasifiable thing of liquid or pressure gas 4 mix in sealed soft bag 2, take place to produce a large amount of gases or the very little gas of density behind the chemical reaction, make folding small size sealed soft bag 2 become balloon body and produce buoyancy.

Two, chemical reaction not taking place, utilizes temperature, pressure change, makes solid or liquid or pressure gas become the floatable black box of the very little gas of a large amount of gases or density:

(1) be fit to changes in environmental conditions, the gasifiable thing that states of matter changes or the parameter of pressure gas are selected:

1, with the gasifiable thing or the pressure gas of temperature environment control states of matter: gasifiable thing or pressure gas 4 are that to be less than or equal to-10.0 ℃ of states be solid or liquid, and are being higher than the material that increases with temperature rising volume that-10.0 ℃ of states are gas.At aircraft just often, aircraft is less than or equal to-10.0 ℃ of environment for floatable black box provides, and gasifiable thing or pressure gas 4 are solid or liquid, and volume is very little.Accidents happened that the back floatable black box leaves aircraft for aircraft, and on the sea, the water surface is higher than-10.0 ℃ of environmental baselines, gasifiable thing or pressure gas 4 become a large amount of gases or the very little gas of density, make sealed soft bag 2 become balloon body and produce buoyancy.The controlled variable of this temperature control states of matter is-10.0 ℃, also can be-10.0 ℃ of a certain numerical value that become between-4 ℃ to+3 ℃.According to gasifiable thing or pressure gas 4 not between different with ocean temperature, the controlled variable that a little higher than seawater 1-25 ℃ temperature of also available selection changes as states of matter.

2, control the gasifiable thing or the pressure gas of states of matter with the pressure environment: gasifiable thing or pressure gas 4 are to be solid or liquid greater than 1.5 atmospheric pressure states the time, at aircraft just often, aircraft provides greater than 1.5 atmospheric pressure environment for floatable black box, gasifiable thing or pressure gas 4 are solid or liquid, and volume is very little.Accidents happened that the back floatable black box leaves aircraft for aircraft, on the sea, when the water surface is less than or equal to 1.5 atmospheric pressure states, gasifiable thing or pressure gas become gas with the pressure material that volume increases that diminishes.Utilization is in aircraft and leave the variation of two kinds of environment of aircraft, the pressure difference that floatable black box is subjected to is as the states of matter running parameter of gasifiable thing or pressure gas 4, before preventing that floatable black box from falling in the water, gasifiable thing or pressure gas 4 also do not gasify or are not gasified totally, external environment condition pressure may be greater than 1.5 atmospheric pressure after floatable black box was fallen in the water, so difference according to gasifiable thing or pressure gas 4, at aircraft just often, aircraft provides greater than 5.0-3.0 atmospheric pressure hyperbaric environment for floatable black box, when aircraft after accidents happened floatable black box leave aircraft and enter the sea fast, behind the water surface, as long as in the water environment less than 5.0-3.0 atmospheric pressure pressure, the gasifiable thing or the pressure gas 4 of solid or liquid can both become gas.

(2) concrete various gasifiable thing or the pressure gas of selecting:

1, with pressure gasifiable thing or the pressure gas 4 that volume increases that diminish is: preferred inert nitrogen gas, argon gas, carbon dioxide, air a certain.A certain or several potpourri of these gases is contained in the sealed soft bag 2, and at aircraft just often, aircraft provides greater than 1.5 atmospheric pressure environment for floatable black box, as 5.0-3.0 atmospheric pressure hyperbaric environment is provided, and makes the smaller volume of these gases.Accidents happened that the back floatable black box leaves aircraft for aircraft, and on the sea, when the water surface is less than or equal to 1.5 atmospheric pressure states, gasifiable thing or pressure gas are subjected to pressure and diminish, and volume increases greatly, and sealed soft bag 2 becomes balloon body and produces buoyancy.Nearly all in theory in fact gas all has with the pressure character that volume increases that diminishes, and all can select for use as hydrogen, oxygen etc., but preferred inert gas is safer, and black box is not had damage effect.

2, rise with temperature and pressure gasifiable thing or the pressure gas 4 that volume increases that diminish is: preferred inert liquid oxidizing gases, a certain as liquid nitrogen, liquid argon, liquid carbon dioxide, liquid fluorine Lyons.A certain or several potpourri of these liquid gas is contained in the sealed soft bag 2, and at aircraft just often, aircraft keeps liquid needed temperature and pressure for floatable black box provides this liquid gas.As the fusing point-210 of liquid nitrogen ℃; Boiling point-195.8 ℃; Critical temperature-147 ℃.The critical temperature of liquid argon is :-122.29 ℃, when temperature of argon gas greater than-122.29 ℃, liquefiable never, only in temperature of argon gas during less than its critical temperature, being added on corresponding pressure could liquefy.Fluorine Lyons chemical property is stable, wherein the most important thing is dichlorodifluoromethane CCl2F2 (F-12), and dichlorodifluoromethane is no gas gas at normal temperatures and pressures; Dichlorodifluoromethane fusing point-158 ℃, boiling point-29.8 ℃, density 1.486 gram per centimeters-30 ℃.The critical temperature of ammonia and carbon dioxide is higher than or near room temperature, such material is easy to be compressed into liquid at normal temperatures.But the critical temperature of oxygen, nitrogen, hydrogen, helium etc. is very low, and wherein the critical temperature of helium is one 268 ℃.Make these gas liquefactions, must accordingly certain cryogenic technique will be arranged, enabling to reach their critical temperatures separately, and then make its liquefaction with the method that increases pressure.As seen gasifiable thing of the utility model or pressure gas 4 usefulness ammonia and carbon dioxide are promptly easily realized again relatively safety, because ammonia is corrosive, then liquid carbon dioxide is that the best of gasifiable thing or pressure gas 4 is selected material for use in the utility model.

Other non-inert liquid oxidizing gases liquid oxygen, liquid ammonia, LPG, liquefied butane, liquefied natural gas (LNG) also can be used for gasifiable thing or pressure gas 4 in theory, but not as inert liquid oxidizing gases safety.

In a word, chemical reaction does not take place, it is liquid carbon dioxide that gasifiable thing of the present utility model or pressure gas 4 select material most.Liquid carbon dioxide gasifies at normal temperatures and is carbon dioxide, after liquid carbon dioxide becomes atmospheric carbon dioxide, volume increases about 500.00 times, just, adorn 1.0 liters of liquid carbon dioxides in the sealed soft bag 2 of floatable black box aboard for floatable black box provides-20 ℃ and 2.0 atmospheric environment., fall into the water as floatable black box after accidents happened at aircraft, sealed soft bag 2 can be changed into the volume about 50.00 liters, and sealed soft bag 2 can be held out the water surface to the black box of 50.00 kilograms of left and right sides weight of dress wherein with buoyancy.If black box has only 50.0 kilogram weights, then only adorn 0.1-0.2 in the sealed soft bag 2 and rise liquid carbon dioxide the floatable black box in the water is emerged.But consider that black box falls into seawater certain depth is arranged, seawater has pressure to the gasification carbon dioxide, and the displaced weight of the gas volume of the carbon dioxide that then gasifies is greater than black box weight.Liquid carbon dioxide is a safety, aircraft is in that just often the liquid carbon dioxide possessive volume is again little, aircraft is just often providing necessary temperature and pressure environment for liquid carbon dioxide again easily, so, liquid carbon dioxide pack in the sealed soft bag 2 of floatable black box into as gasifiable thing or pressure gas 4, and making floatable black box after accidents happened at aircraft can the emersion upstream face be a kind of good technical scheme.

(3) floatable black box of dress liquid carbon dioxide steel cylinder principle in the imitative Aircraft life-saving clothing of stay-supported switch:

But a high pressure vessel steel cylinder that gasifiable thing of liquid carbon dioxide or pressure gas 4 are housed as openable container 5, is put into sealed soft bag 2, be connected on the switch of steel cylinder opening with a rope, this root rope is connected in again on sealed soft bag 2 inwalls.Also establish an easily broken rope on sealed soft bag 2 outer walls, the easily broken rope of this root on the outer wall is connected on the aircraft again.Aircraft is after accidents happened, floatable black box leaves the instantaneous of aircraft, the easily broken rope of this root on the outer wall is earlier with the pulling of the rope in the sealed soft bag 2, open the switch of steel cylinder opening or make the pull bar gyration, during rotation default pricker punctured the diaphragm in the high-pressure gas steel cylinder, liquid carbon dioxide in the high-pressure cylinder enters sealed soft bag 2 and becomes carbon dioxide, and sealed soft bag 2 produced buoyancy after gas expanded.

(4) floatable black box of dress liquid carbon dioxide steel cylinder principle in the imitative Aircraft life-saving clothing of sensing switch:

But a high pressure vessel steel cylinder that gasifiable thing of liquid carbon dioxide or pressure gas 4 are housed as openable container 5, put into sealed soft bag 2, but the opening part of openable container 5 is provided with switch 6; This switch 6 is to be subjected to temperature controlled switch, or this switch 6 is the switches that are subjected to the control of static pressure, or this switch 6 is switches of electromagnetic force control, or this switch 6 is switches of vibration force control, or this switch 6 is switches 15 of humidity control.The switch parameter of these switches is selected as those switch parameters in the imitative flame snuffer principle of above-mentioned generation chemical reaction.

The switch 15 of humidity control comprises switch valve 16 and humidity sensor 17 at least; But the opening part of each openable container 5 is respectively equipped with switch valve 16, but or the opening part of each openable container 5 all use same switch valve 16; All or part of of humidity sensor 17 is positioned at the outside of sealed soft bag 2, and humidity sensor 17 is connected with switch valve 16, and gauge tap valve 16.When black box falls into the water, humidity sensor 17 touches water, humidity sensor 17 sends the opening signal of opening switch valve 16, switch valve 16 is opened, but liquid carbon dioxide or pressure gas in the switch valve 16 place openable containers 5 are emitted, the sealed soft bag 2 of black box outside is dashed to expand, and sealed soft bag 2 becomes balloon the black box of interior dress is climbed up on top of the water.
