Description

Automatic inflatable lifesaving bar

The utility model relates to a kind of aquatic life-saving equipment, particularly a kind of automatic air heave type single emergency device waterborne.

Existing aquatic life-saving equipment is a lot, but mainly contain life jacket, buoy quoit, liferaft, life boat etc., for liferaft and life boat all is to be on the scene and could to rescue after finding have the people to rescue, time is longer, cause the rescue failure easily, life jacket need be put in advance could be effectively, then invalid for the people who does not put in advance, buoy quoit can be thrown near the drowning people, make the drowning people catch the back and be rescued, but because the buoy quoit volume is big, relatively heavier, cast is nearer, and be difficult for skishing target, person far away is then invalid for distance, it is 86103322 " inflated water lifesaving appliances " that Patent Office of the People's Republic of China discloses a number of patent application in November, 87, the disclosed solid type gas generator that has electric igniter of this device has simple in structure, aeration speed is fast and stable, gas is pure, advantages such as nontoxic non-corrosiveness, it is a kind of compressed air source unit preferably, but because this lifesaving appliance still need be carried at the crewman and just can work on one's body, then invalid for the people who does not carry this device, can not all carry for general passenger, this just makes the rescue scope be very restricted, simultaneously, the electric igniter of this device be utilize water electric conductivity after amplifying and energized has determined this device to meet water and will work, make and deposit difficulty, as deposit and badly will be moved by water enchroachment (invasion) is wet, also be easy to misoperation in a humid environment.

The purpose of this utility model is in order to overcome the weak point in the above-mentioned technology, provides a kind of and helps throwing and needn't everyone volume of taking with oneself little, in light weight, the single emergency device that reliability is high.

The purpose of this utility model can realize by following measure:

For the ease of throwing, design stub of a kind of outer appearance or resemble the saving bar of a flash light, the powder column of battery, switch, electric igniter, solid gas forming agent, colation cooling layer and air bag all are contained in the barred body, and it is little to make it volume, in order to throwing at a distance accurately.In order solving to meet water or make moist the problem of misoperation to take place, to change electronic switch into hydraulic type switch that the pressure that needs water could energized, saving bar must could be worked when sinking under the water certain position.In barred body that air bag is also packed into, adopt the rubber fabric of industrial bright and beautiful silk fabric gluing or polyamine fat cloth to make " shape of a hoof " in advance and after folding, put into barred body, in case during inflation, just can go out the barred body top cover and form " shape of a hoof " buoy quoit for ease of use.For the ease of mounting or dismounting, barred body is made up of water inlet lid, pressure-sensitive cavity, barred body shell, caput housing and top cover.The hydraulic type switch is made up of rubber diaphragm, pressure-sensitive cavity, movable push rod, antivibration spring, movable contact spring and static contact, the elastic force of antivibration spring is relevant with the degree of depth that needs submerged, and can make switch have certain shake-proof ability, during in water enters into the water lid and to rubber diaphragm generation pressure, this pressure is during greater than the elastic force of antivibration spring, switch connection, saving bar just become " shape of a hoof " buoy quoit.

The utility model compared with prior art, its distinguishing feature is whole parts all are contained in stub of an outer appearance or resemble in the clavate housing of a flash light, volume is little, in light weight, throw far away, accuracy in placement, aeration speed is fast and stable, be not subjected to humidity effect, ambient temperature subzero 25 ℃ can normal operation to the scope above freezing 50 ℃, safe and reliable, lifesaving rate height, be convenient to deposit, the water survival that extensively is adapted to river, river, lake, sea uses, and is a kind of desirable emergency life support apparatus (ELSA) waterborne.

Accompanying drawing is the constructional drawing of automatic air heave type water survival rod.

In conjunction with the accompanying drawings saving bar is described in detail as follows:

Water inlet is covered 1 and is threaded with pressure-sensitive cavity 5 usefulness and compresses rubber diaphragm 2, antivibration spring 3 is enclosed within on the movable push rod 4, movable push rod is contacted with rubber diaphragm, movable contact spring 6 is contained in the contact of the other end of movable push rod as switch, a static contact 7 another contact as switch is arranged in the front of movable push rod sense of motion, seal ring 8 is housed between pressure-sensitive cavity and the barred body shell 12 also to be tightened with nut 9, battery 10 is housed in the barred body shell, connector 11 and gas generating device housing 13, electric igniter 14 is housed in the gas generating device housing, powder column 15, medicine cover 16, filtering net 17, cooling system conditioner 18 and air gate 19, the switch series connection back that pig-tail wire footpath connector and the movable contact spring and the fixed touching plate of electric igniter are formed is connected with battery, it is repressed the forming of prescription of 86103322 solid gas forming agents that powder column uses number of patent application, medicine is covered with many air extractor vents, the other end of barred body shell adopts with caput housing 22 and is threaded, the material that the rubber fabric of the industrial bright and beautiful silk fabric gluing of air bag 21 usefulness or polyamine fat cloth or other are fit to do buoy quoit make in advance " shape of a hoof " shape and with India rubber tube 20 bonding jails, the other end of India rubber tube 20 is enclosed within on the air gate 19, and it is fastening with lasso at socket place, be placed on airbag fold in the caput housing well then, it is unimpeded that air bag folding should help gas, at last top cover 23 is enclosed within on the caput housing, wherein, caput housing and top cover are to make with flexible plastic, the barred body shell is to make with duroplasts, about 600 grams of the total weight of saving bar, center of gravity is near the caput housing.During use, be thrown into saving bar near the drowning people or the updrift side of current, submerged was 20 to 80 centimetres after saving bar fell into water, the pressure of water is greater than the elastic force of antivibration spring, rubber diaphragm moves movable push rod, the switch connection that movable contact spring and static contact are formed, electric igniter is switched on power supply and ignites, powder column is heated and produces nitrogen, overflow from the air extractor vent of medicine cover, after filtration with the cooling after, can obtain about 45 ℃ pure nitrogen at air gate, by India rubber tube to airbag aeration, just after air bag has had certain gas, go out top cover and rapidly inflation become " shape of a hoof " buoy quoit and emerge, as long as the drowning people catches near the buoy quoit floating to just can be rescued.After the use, as long as just change new powder column and electric igniter can be reused.
