Description
Technical field
This utility model is related to a kind of small space personnel operation, escape, lifesaving appliance under water, and in particular to a kind of semi-closure
The solid oxygen rebreather of formula.
Background technology
Respiratory organ is a kind of Portable, personal preventer, is mainly used in environment anoxia or there is toxic and harmful danger
And human life it is safe when, the wearable respiratory organ of personnel realizes the protection of respiratory system, so as to safe escape hazardous area.
People often carry out operation, exploring in the water surface or water, run into emergency, and needs are escaped under water
Raw, lifesaving, such as：Helicopter falls over into water, submarine accident, amphibischer Panzerwagen have an accident, colliery floods, under water operation in narrow space, and people
The limited time held one's breath, majority's breath holding time 60-90 seconds, it is necessary to which rebreather is escaped helping people.
The oxygen source of respiratory organ is typically divided to two kinds of steel bottle type compression oxygen source and Chemical Oxygen Source.Steel bottle type compression oxygen source is by air
Or oxygen compression is stored among steel cylinder；Chemical oxygen is using personal breathing system made by chemical drugss chemical reaction life oxygen principle
Blanket insurance protection unit.Chemical Oxygen Source is also divided to two kinds：One kind is using peroxide or superoxides and water and CO2Reaction generates oxygen
Gas, one kind is that pyrolysis occur using rich oxygen containing chlorate or perchlorate to release oxygen.Steel bottle type self-rescuer volume
Larger, heavier-weight, maintenance is complicated, carries inconvenient.Peroxide or superoxides self-rescuer product oxygen efficiency are relatively low, during oxygen supply
Between it is shorter, be only capable of using more than ten minutes, and current isolation type peroxide self-rescuer, medicine outside is provided with one and opens
Dynamic raw oxygen oxygen candle, increased the volume of self-rescuer, inconvenient using carrying.
At present the oxygen source of underwater breathing typically takes steel bottle type to compress oxygen source, and steel bottle type self-rescuer volume is larger, weight
Amount is heavier, and maintenance is complicated, carries inconvenient.Particularly volume is larger, in small space using extremely inconvenience, has a strong impact on narrow and small
Job space progress, the best opportunity for affecting escape lifesaving adversely, the person's of giving people life security brings greatly threat.
The content of the invention
The purpose of this utility model is to overcome the above-mentioned not enough of prior art and provide a kind of life-span length, small volume, weight
Amount is light, carry a kind of half-closed solid oxygen rebreather easy to use.
Technical solution of the present utility model is：Chlorate oxygen candle oxygen generator and carboloy dioxide canister top phase
Connection；Interface is connected with air bag lower interface on carboloy dioxide canister；Interface is equipped with mouth tool group on air bag.
The oxygen generator be chlorate oxygen light up oxygen generator, including starter, ignition powder, oxygen candle, thermal insulation layer,
Gas purification medicine layer, generator metal shell；Oxygen candle upper end is equipped with ignition powder, center and the ignition powder center of starter
It is corresponding.
The Starting mode of the starter is that the mechanical type striker impact fire in a stove before fuel is added is lighted a fire or electric ignition, to start oxygen candle.
The oxygen is lit up based on sodium chlorate, addition fuel titanium valve, iron powder, catalyst cobalt hydroxide, chlorine-inhibiting agent peroxidating
Barium, stabilizer potassium hyperchlorate, silica flour, binding agent Kaolin, powder mix homogeneously compacting is formed.
The gas purification medicine layer is hopcalite, Na2O2, molecular sieve absorbents.Absorb H2O、Cl2、CO2, CO etc. it is micro
Foreign gas, the oxygen for making output reaches《Medical oxygen》Standard, directly can breathe for people.
The built-in carbon-dioxide absorbent calcium hydroxide of the carboloy dioxide canister, absorbs the carbon dioxide of characteristics of contaminated respiratory droplets.
Carbon-dioxide absorbent is calcium hydroxide, sodica calx（Soda lime）, a kind of, any two kinds of combinations in Lithium hydrate or three kinds.
Nose clip (10) is connected with the pneumostome tool group (8).
The air bag volume is that 4～10L ensures human body respiratory capacity.The air bag top is divided into circular cone stage body, it is to avoid air bag
Personnel's sight line is blocked when heaving, the freedom of movement of person head is limited.
Vertical dimension between the air bag front has a relief valve, relief valve and mouth to have is 20～40cm, reduces breathing resistance
Power, it is to avoid personnel's breathing fatigue.
There is a fixation belt at the air bag back side, for securing the air-bag to human body front, it is to avoid heave limit because of air bag
Physical activity processed；Belt is axially connected in air bag lower cylinder with air bag in wire type, it is ensured that the one side of air bag energy is close to chest,
It is easy to the fixation of air bag, reduces impact of the buoyancy to air bag；
Central angle of the air bag on the air bag cylindrical cross section corresponding to two junction points of belt and air bag is 120 °
～150 °, it is ensured that in the case that human chest fixation is close at the air bag back side, air bag can freely shrink when personnel breathe.
The air bag upper end is connected with mouth tool group, lower end and carboloy dioxide canister（2）It is connected.
The contrary one-way cock of air-breathing expiration both direction, breather cheek valve door and airbags are set in the mouth tool group
Logical, expiratory one-way valve door Jing airways are connected with carboloy dioxide canister bottom；Mouth tool group front end is provided with a waterproof valve, prevents
Water enters air bag and carboloy dioxide canister.
This utility model compared with prior art, life-span length, it is lightweight, carry easy to use, it is adaptable to narrow and small sky under water
Between operation, distress personnel escape, lifesaving uses.Its advantage is also resided in：
(1) oxygen candle life-span length of the present utility model, without the need for spare part, ensures more strong, non-maintaining, it is possible to reduce equipment
Inspection and maintenance expense afterwards；
(2) oxygen candle oxygen-producing amount is high, and under conditions of equal oxygen is produced, the volume of oxygen candle only has high-pressure oxygen cylinder volume
1/3, be self-rescuer production, transport, storage, carry provides convenient；
(3) oxygen candle can carry out oxygen supply according to the offering oxygen way of prior design, without the need for adjusting, using simple and reliable；
(4) oxygen candle is stored and Keep Clear-High Voltage using existing under atmospheric pressure state, not.
