Abstract

The utility model relates to a life-saving device in water. An aerogenous control device of the life-saving device in water is composed of electronic components; a eupyrexia resistor of the aerogenous control device and solid propellant on the periphery of the eupyrexia resistor are arranged around a piston. Lquid reactant is pushed by the piston to be jetted onto laminated plastic foam, and the liquid reactant reacts with solid reactant in the piston to produce gas, so an elastic gas bag wrapping the outer side of the piston can be inflated. The utility model has the advantages of simple structure, small size and convenient use, and the inflation speed of the gas bag is quite high. The utility model can not produce pollution material, which is suitable for the self-help in water and the accidental self-help of operation at sea, combat, fighting flood and rescuing from danger, swim, operation at deep water, etc.

Description

Life-saving device in water

The utility model relates to safety apparatus on a kind of automatic aerated water

The technical scheme of existing life-saving device, as " drowned automatic lifesaving device " (notification number CN2090804U, application number: 91214063.1), its shortcoming is that the automatic control inflation mechanism is mechanism's mode, complex structure, reliability and sensitivity are not as the electronic auto-control mode.Other has " automatic inflation swimming emergency lifesaving appliance " (notification number CN2101637U, application number: technical scheme 91209604.7), its weak point is still to need the manually gas filed beginning of control, and liquid reactants only contacts with solid reactant by opening aperture outflow, can't be fast, fully mix, influence speed of response.In addition, more than the technical scheme of two patent announcements, all be to adopt the acid-base neutralization reaction to produce carbon dioxide to put on the air, contrast spontaneous oxidation-reduction reaction gas making, under the same terms, the speed that gas takes place is slow, efficient is low.

The purpose of this utility model is: provide a kind of light, can carry, designs simplification, material be easy to get, can the reliable sensitive control inflation that triggers automatically, the life-saving device of pollution-free gas takes place efficiently, fast.

The purpose of this utility model is achieved in that and comprises elastic bag, aerogenesis control setup, reactant and storing apparatus thereof.Stick on the graphite of elastic bag outside face and metal aluminium flake two electrodes as stealthy battery, as humidity sensor, in water, produce a voltage, trigger transistor circuit, little resistor wire is heated in conducting, cause the moment decomposition of a spot of propellant of resistor wire on every side, emit gas, promote piston, the liquid reactants in the compression liquid storage tube is ejected into reactant fast and is filled with in the laminated placement foam-plastic blocks of solid reactant, make reactant (liquid oxidizer and solid reductant) rapid mixing, immediate response produces nitrogen, and elastic bag is risen greatly, becomes survival kit.

Contrast close technical solution, the utility model has following advantage: 1, adopt the high efficiency compound compositing formula of the spontaneous generation oxidation-reduction reaction of energy, liquid reactants is by spraying and the solid reactant rapid mixing, and gas making is rapid.2, resultant of reaction is pollution-free, and the nitrogen of generation is the big gas of safety.3, humidity sensor adopts graphite and metallic aluminium two electrodes to form the form of stealthy battery, no-voltage output on the electrode at ordinary times, but in water, can become a battery, could export enough control voltage.Can be because of the big false triggering of air humidity, voltage signal amplifies through transistor again, has guaranteed to trigger inflation automatically when getting into danger water environment, and is reliable, sensitive.4, this device major part can be by injection molding, and material is easy to get, and volume is little, is easy to carry.5, gas-forming substance sealing, long shelf-life.

Now in conjunction with the accompanying drawings concrete enforcement is described.

With reference to figure (1,2), be pasted with graphite flake 1 and metal aluminium flake 2 with conducting resinl on the outside face of air bag 12, graphite flake 1 and metal aluminium flake 2 are formed the two poles of the earth of stealthy battery.Graphite 1 is as anodal in water, and aluminium flake 2 is as negative pole, and the voltage between the two poles of the earth generally is 0.5-1.0 volt voltage (deciding on electrolyte content in the water).This voltage is received transistor BG by the tiny lead that connects electrode, passes air bag 12 ₁Emitter and base stage, transistor BG ₂Base stage be connected in resistance R ₁With BG ₁Collecting electrode between, BG ₂Collecting electrode meet BG ₁Emitter, simultaneously again by slight resistance to heat R ₂The anode of power connection 3, resistance R ₁The other end and BG ₂The negative pole (BG of emitter power connection 3 ₁, BG ₂Be connected into the Darlington transistor form).Graphite flake 1 Darlington transistor BG with the voltage control of metal aluminium flake 2 ₁, BG ₂The conducting situation, thereby control low-grade fever resistance 4(R ₂) whether conducting is generated heat.Resistor wire 4(R ₂) around have a spot of solid propellant peroxidating ring ketone in the sixth of the twelve Earthly Branches 6(amount be 0.5～2g) or other material that decomposed by the low-grade fever instantaneous heat to produce gas such as black powder, nitrocellulose,

Wet goods, the low-grade fever resistance R ₂And peroxidating ring ketone in the sixth of the twelve Earthly Branches 6 be in piston 5 around, promote piston so that produce gas, the liquid reactants 8 that compression liquid pipe is 7 li, make liquid reactants 8 push a small amount of petroleum ointment sealing layer 9 of the mouth of pipe open, flow along the plastics tubule 10 that some apertures are arranged, and be ejected into fast the foam layer that is filled with solid reactant 15 11 of laminated arrangement from aperture 101, (accompanying plastic pipe 10 between the two layers of foam plastic layer 11) reacts immediately, produce gas, elastic bag 12 is risen greatly, performance rescue effect.Electronic circuit board 13, liquid storage tube 7, foam layer 11 etc. are fixing in aggregates by plastic frame 14.Gasbag outer surface is provided with elastic 16, respectively this device is locked at place, arm oxter, the left and right sides for the user, holds the human body come-up after the inflation.

Contain oxidizer KNO in the liquid reactants ₂And have and promote and the NaOH of stabilization solid reactant deoxidation compound N ₂H ₂H ₂SO ₂, content respectively is 32～35%, 1～20%, 38～58%.Total consumption: children 15～25g, 25～40g grows up.In the above-mentioned substance, NaOH has following effect: reaction is preceding, stable nitrite solution, prevents to generate HNO ₂, emit NO ₂During reaction, in and H ₂SO ₂, discharge N ₂H ₄, promoting reaction, the acidity of residual solution is eliminated in the reaction back.

The also available NaNO of oxidizer ₂, the also available N of deoxidation compound ₂H ₄2HC1.
