Description

Automatic life-buoy for drowning man

The utility model relates to a kind of water survival facility, particularly a kind of when the people is drowned automatic or manual control the drowned automatic lifesaving device of rapid inflatable lifesaving.

Existing water survival utensil, the buoy quoit of makeing as kapok or foamed plastic, life jacket etc., its shortcoming is that volume is big, inconvenience is carried; Manual inflation or pressurized air inflatable air bag formula life saving apparatus, its shortcoming are must be standby at sufficient gas before the following water, and volume is big, and also inconvenience is carried.Especially operation at sea, flood-fighting, swimming etc., it is very inconvenient to carry life." swimming life-saving belt " shortcoming (CN86106182) is to have only manual control device, for the drowning often out of reach lifesaving purpose of the person that is not able to swim, the mixing and the chemical reaction velocity of its chemical substance are slower, the lifesaving poor effect, chemical reaction slowly takes place in equipped standby chemical substance moisture-sensitive, and effective age is short.

The purpose of this utility model is to provide a kind of drowned automatic lifesaving device product, has when people are drowned when being dying to be badly in need of automatic or manual control inflatable lifesaving, and inflation fast (2-5 is in second) is standbyly carried the air bag unaerated, and volume is little, and characteristics such as be easy to carry.Waterborne the saving oneself and the unexpected use of saving oneself of falling into water of suitable operation at sea, overwater bailout, flood-fighting, swimming etc.

The utility model be achieved in that drowned automatic lifesaving device by air bag, gas generator and automatically and manual control device and safety switch constitute.The employing reaction is fast, the many chemical substances of reaction back generation gas, as sodium bicarbonate and hydrochloric acid or natrium carbonate and sulfuric acid or ammonium bicarbonate and hydrochloric acid or sodium bicarbonate and sulfuric acid.The leading portion part of air bag fuses with the port part of the housing of gas generator and constitutes chemical reaction chamber.Air bag is made many air chambers (or single air chamber), is communicated with breather cheek valve between each air chamber and the catalyst chamber, and each air chamber is provided with exhaust and chews, so that with the back emission gases.The profile of air bag can be made various ways such as belt type, vest type, annular.Acids aqua thing is contained in the medicine bag made from the flexible plastic of resistance to chemical attack, medicine bag is compressible to change, with sealing film phonograph seal, be placed in the gas generator, adopt the nail thorn to open bag, the Taper Pipe of opening bag is placed on the medicine bag the inside, bases pulvis thing (also can convert water and be diluted to liquid object) is placed in the catalyst chamber of the shell ends oral area of gas generator and air bag leading portion, pressing mechanism adopts spiral compression spring and extrusion plug and buckle to constitute, be arranged on medicine bag in the gas generator below, its role is to push the film that seals that Taper Pipe punctures medicine bag, and extrude acids aqua thing and spray in the catalyst chamber and bases pulvis thing generation chemical reaction.The shunting disk that has many fluid holes is equipped with in the exit of medicine bag, and acid solution is sprayed on the bases pulvis thing equably.Automatically be arranged on the bottom of gas generator with manual control device and safety switch, available safety switch pins automatic and manual control device simultaneously.Automatic control device discharges pressing mechanism with mechanical compression diaphragm control level Four transmission levers card, the amplification ratio of lever card is 1:10-20, utilize the pressure control mechanical compression diaphragm action of the depth of water, lever card by the level Four transmission amplifies, and the buckle of pressing mechanism and the claw of level Four card are thrown off.The bottom of gas generator to press mold dish and snap seats has the inlet opening, and when inflating in order to overcome, because the parital vacuum difference of pressure of the mobile formation of extrusion plug is blocked with the water blockoff plug at ordinary times, the water blockoff plug is contained on the extrusion plug and in company with extrusion plug and moves together.Standbyly carry the air bag unaerated, foldable regularly pack in the leather sheath with gas generator, buckle on the leather sheath, be convenient to hang between waist and carry, also air bag can be worn, gas generator hangs between waist and carries.When being badly in need of, open insurance, enter catalyst chamber by the chemical substance in the automatic or manual control setup control gaseous producer chemical reaction sharply takes place, discharge a large amount of gases, rapid sufficient air bag produces the buoyancy lifesaving.

The utility model has following characteristics compared to existing technology: do not inflate when 1, standby, volume is little.2, can with behind the air bag folding and gas generator be packaged in and hang in the leather sheath between waist, also air bag can be worn, gas generator hangs between waist and carries, and is easy to carry.3, air bag is made many air chambers, and each air chamber is communicated with breather cheek valve with catalyst chamber, damages certain air chamber in order in using, and other air chamber plays the lifesaving effect in the same old way.4, air bag can be made various ways such as belt type, vest type, annular, extensively adapts to various range of uses, as operation at sea, overwater bailout, flood-fighting, swimming etc. waterborne save oneself, the unexpected use of saving oneself of falling into water.5, the leading portion of air bag is a main reaction chamber partly, make the volume of gas generator littler, and catalyst chamber is big, and inflation is (2-5 second) rapidly, and lifesaving is effective.6, adopt the mechanical compression diaphragm, with level Four transmission levers card the action force of pressure-sensitive diaphragm is amplified 10-20 and doubly control the release pressing mechanism, utilize the pressure of the depth of water to realize automatic guidance, control reliably, and is highly sensitive.7, have manual control device and safety switch simultaneously,, can fall into water and save oneself for the person that is not able to swim, also can before Lin Xiashui, inflate standby, for water under the person of being able to swim can select as required gas filed opportunity with whether inflate.8, equipped standby chemical substance is that lattice are from splendid attire and sealing respectively, and its effective age is long.
