Abstract
The utility model relates to an automatic inflated life-saving bar, which is a single-person life-saving apparatus for emergency life-saving when accidental falling into water happened in rivers, lakes, the sea, reservoirs, harbors, etc. The automatic inflated life-saving bar is composed of water activated batteries, an electric igniter, a gas releasing device, an air bag, a casing, etc. The water activated battery is wound on the centre shaft of a battery sleeve via a medicine foil which is composed of a plurality of chemical components, and is pressed and connected with leading wires of the electric igniter via two wiring connectors; the water activated battery generates chemical reaction and releases electric energies quickly under the action of water; the ignition is synchronous, and a U-shaped life buoy is formed by the automatic inflation to the air bag. The automatic inflated life-saving bar has the advantages of high inflation speed, high safety, high life-saving rate, compact structure, small size, light weight, far distance of throwing and accurate point of descent.
Description
The utility model relates to a kind of automatic inflation type single emergency life support apparatus (ELSA) waterborne.
Existing buoyant apparatus is a lot, the life jacket, the buoy quoit that are fit to single emergency survival are arranged, life boat that is suitable for going into emergency survival etc. is arranged more, all each has something to recommend him and its weak point is arranged, as life jacket, buoy quoit and so on, can only be effective to the owner, target is difficult to skish, and cast is limited, influence the lifesaving rate, and life boat is often slipped up because of having little time to catch up with the time.A kind of air heave type saving bar that appears on the market now, adopt the hydraulic type switch, directly utilize the pressure energized of water, this lifesaving hold in both hands must entry 20～30 centimetres the degree of depth, could produce certain pressure, must overcome ability energized behind the spring force again, making the igniting time ratio of getting angry slower, need be passed to the process of contact behind its rubber diaphragm pressurized, be subjected to the influence of burn-in effects or spring strength error, all reduced reliability to a certain extent as Rubber Parts through action.The air heave type saving bar that another kind appears on the market, adopt electronic switch and common heavy-duty battery, electronic switch has two contact studs, profit uses water as conductor, with rapid energized after the two contact stud short circuits, but its holding time of general battery be 1 year, change battery after 1 year again, bring the difficulty of changing battery to the user, just in case forget the replacing battery, the lifesaving effect equals zero.
Task of the present utility model is to avoid the deficiency of above-mentioned technology, and the automatic air heave type saving bar that a kind of inflation is rapider, use is more reliable, safe is provided.
The utility model is realized by following scheme: comprise housing, battery is housed in the housing, electrical igniter is housed in the seat of getting angry, the gas generating device in the cover of getting angry with fold after shape of a hoof air bag communicate, its invention is that described battery is a water activated battery, the medicine paper tinsel circumvolution of being made up of various chemical components is on the axis of battery tube, and the gag that is fixed on battery tube small end and can be pulled away from battery cover with the battery cover and the close-fitting of its formation inlet channel, and two connector crimping are directly adopted in being connected of going between between water activated battery and electrical igniter.Gag after utilization is pulled away from make water rapidly by inlet channel irritate to the medicine paper tinsel and simultaneously attack discharge the electric energy of high potential, big electric current rapidly, realize light a fire, get angry, inflating synchronous.
The utility model compared with prior art, kept the volume of former technology little, advantages such as in light weight, cast is far away, accuracy in placement, structure is further simplified, owing to adopted water activated battery, not only Keeping life can reach 4～5 years, and voltage height, electric current are big, so the rapid aeration speed of igniting is faster, use safety and reliability, the lifesaving rate is higher, is widely used in the water survival use in river, river, lake, sea, reservoir, bay etc. various climatic conditions under.
Accompanying drawing 1 provides the structural representation of the utility model.
In conjunction with above-mentioned accompanying drawing embodiment the utility model is remake and to elaborate.
From accompanying drawing 1 as can be known, automatically the housing of air heave type saving bar is with plastic production, profile such as clavate or torch tubular or grenade shape, and this shape facility is suitable for throwing, and is that the weight of accuracy in placement guarantees.Housing is a main body part in addition with barred body (13), big end is a gasbag chamber, top cover (1) is pressed into its close-fitting, small end is the battery chamber, be spirally connected with nut (15), push down battery cover (17), make between battery cover and the battery tube (16) and form inlet channel with three-jaw structure by omoplate in the nut, seal ring (21) waterproof is leaked, and close-fitting the gag (18) that can be pulled away from the battery cover.Described gag is pulled away from mechanism backguy (20) and draw ring (19) promptly is set on gag.
Parts in addition such as water activated battery, electrical igniter, gas generating device, the shape of a hoof air bag after folding are housed in the housing.Owing to adopt water activated battery, realize light a fire, get angry, inflate synchronously, and voltage height, electric current are big, so light a fire, inflationtime is rapider.Medicine paper tinsel (14) circumvolution that water activated battery is made up of number of chemical composition such as cmpds such as magnesium, chlorine is on the battery cover (17) that is located at barred body (13) small end on the axis of battery tube (16).Being connected of lead-in wire directly adopts two connectors (12) crimping, electrical igniter (10) to be contained in the seat (11) of getting angry between water activated battery and electrical igniter (10).
In the cover (22) of getting angry of gas generating device the medicine cover (8) with a plurality of air extractor vents is housed, the prescription of selecting the patent No. 86103322 solid gas forming agents for use is housed in the medicine cover suppresses the solid powder column (9) that forms, between the filtering net (7) filtering medium (6), the filtering medium top is pory dividing plate (23), communicate with the air extractor duct (5) of the cover of getting angry, air extractor duct is inserted in the air inlet pipe (3), and is fastening with locknut (4), makes with air bag (2) to communicate.
Air bag (2) adopts industrial bright and beautiful silk polyurethane cloth to be pressed into the shape of a hoof through cutting, and periphery is equipped with climbs the band (not shown), helps the drowning people that saving bar is pulled to and is inserted in health at one's side, and air bag is put into the big end gasbag chamber of housing after folding.
The saving bar total weight is about 600 grams, and buoyancy can reach 78.4N, and inflationtime was less than 5 seconds automatically.Through the test of making moist, in the environment of relative humidity 85～90%, do not see the misoperation phenomenon takes place.
During use, pull out with the gag (18) of draw ring (19) earlier water activated battery, again saving bar is thrown near the drowning people or the updrift side of current, water is promptly irritated rapidly to medicine paper tinsel (14) from the battery cover inlet channel, and cause chemical reaction and discharge electric energy with the medicine paper tinsel, transfer to electrical igniter (10) by lead-in wire and connector, thereby the powder column of the gas generating device that ignites (9), powder column is heated and generates nitrogen, overflow from the air extractor vent of medicine cover, through filter screen and filtering medium, inflate to air bag (2) through air extractor duct again, just wash out top cover after the gas of certain pressure has been arranged when air bag, go out barred body and expand into horse shoe life buoy rapidly and bubble through the water column, as long as just the drowning people catches buoy quoit to be rescued.After saving bar used, only the gas generating device and the water activated battery that need more renew just can be reused.
