Abstract
The invisible life jacket of the invention consists of a gas generator, a vessel and an airbag. The airbag (attached drawing, 1) has a plurality of lifesaving floating bodies which can keep inflation state separately and when unaerated, the airbag takes the shape of a thin belt. The gas generator (not lined out in the attached drawing) is a container divided into two cavities. The vessel (attached drawing, 3) connects the airbag with the gas generator.. A user puts on the invisible lifesaving jacket before gonging into the water. When the swimmer is in danger or the lifesaver approaches the victim, open the charge valve on the gas generator of the invisible lifesaving jacket and shake, then the airbag puffs fast and the invisible lifesaving jacket acts as a lifesaving jacket. The proportion and dosage of gas generation substance added into the invisible lifesaving jacket should be strictly in accordance with the instruction labeled in the specification before using the lifesaving jacket and periodic security checks are indispensable.
Description
Affiliated technical field:
The present invention is a hidden lifejacket, is a kind of life preserver that is used for being different from of lifesaving or swimming activity life jacket commonly used or buoy quoit.
Background technology:
People for the safety of self, need wear life jacket or buoy quoit when lifesaving or swimming.But life jacket or buoy quoit but produce adverse influence to lifesaving or swimming activity in my life security of protection.The lifesaver can not be very fast near subject of salvage; Swimmer's swimming activity is subjected to certain restriction, influences the effect of swimming exercise, in this case, some swimming fans is all arranged because of being reluctant to wear the life jacket loss of life every year.
Summary of the invention:
In order to overcome the disadvantage of traditional life jacket, buoy quoit, the present invention is designed to stealth with life jacket (buoy quoit), and promptly under normal circumstances volume is very little for its lifesaving floating body.
The technical solution used in the present invention is: change the floating body of traditional life jacket (buoy quoit) into air bag, when needing, give airbag aeration by gas generator by the ventilation flue.The air bag profile can be several patterns, as: can be twice thin, inflatable adhesive tape (as the dress trousers suspender belt); Or be one waist-belt, (as Sam Browne belt) also can make the vest pattern.In swimming activity or lifesaving early stage, hidden lifejacket is in not inflated condition, coming into effect relief or swimmer near subject when causing danger situation, open charge valve, shake a little, two kinds of materials in the gas generating unit mix the back chemistry reflection take place, and produce enough gas, make air bag in seconds full, swimmer or lifesaving rescuer can obtain safety control as wearing common life jacket, buoy quoit.
The present invention is simple in structure, and its beneficial effect is: the lifesaver can implement relief faster; The swimmer can better carry out swimming exercise under situation about ensuring the safety of human life.
Description of drawings:
Hidden lifejacket is made up of gas generator, air bag and three main portions of conduit.
Accompanying drawing is a scheme drawing of the present invention.Among Fig. 1,1,2 is two cavitys of gas generator, holds the liquid of two kinds of aerogenesis respectively; 3 is valve body, cavity barrier film 4 can be opened with handle 7 rotations, makes the mixing 5 of two kinds of liquid in the gas generator be gas vent, and the gas that gas generator produces from then on mouth enters the ventilation flue, enters four～six air bags then; 6 are cavity connection sieve bolt; 8 are the antiseepage plug, leak in order to prevent the aerogenesis material.Among Fig. 2,1 is the individual air bags of four (or six), is the buoyancy aid of hidden lifejacket; 2,3 is the ventilation flue, by the ventilation flue gas that the cavity producer produces is sent into air bag; 4 is aie escape valve, and after airbag aeration used, it was standby to bleed off gas; 5 is boiler check valve, and its effect is when the air bag qi of chong channel ascending adversely is used, and as certain air bag breakage, is unlikely to make the gas leakage of other air bags; 9 is safety valve, and when gaseous tension surpassed safety value, safety valve was opened automatically, and assurance air bag, conduit and gas generator can not blasted because of air pressure is too high.
The specific embodiment:
One, the structure of hidden lifejacket and installation
Hidden lifejacket can be produced and be large, medium and small three kinds of models.The gas generator cavity of every kind of model and the size of air bag, conduit thickness, aerogenesis material consumption should require design according to buoyancy.
1, when hidden lifejacket uses for the first time, number of assembling steps is as follows: 1., with the cavity of gas generator (among Fig. 11,2) separately, in gas generator cavity 2, adorn a kind of aerogenesis material of people (as aluminium sulphate) earlier, 2., load onto barrier film (among Fig. 1 4) at the cavity mouth, 3., cavity 1 firmly is connected with cavity 2,4., another aerogenesis material (sodium bicarbonate) is packed in the gas generator, 5., with gas vent with safety plug (among Fig. 1 8) shutoff, 6., with the conduit of air bag (among Fig. 22,3) and in the firm outlet that is connected on gas generator of air bag (among Fig. 2 1).
2, the charge valve of gas generator (among Fig. 1 3) is designed to revolve and turn 90 degrees abovely, the cavity barrier film can be opened to guarantee charge valve, and two kinds of aerogenesis materials can fully be mixed.
3, the volume of two kinds of aerogenesis materials is 90% of a gas generator cavity volume, and two kinds of aerogenesis materials can fully mix when opening barrier film with assurance.
Two, the use of hidden lifejacket
1, swimmer or lifesaver be before following water, on one's body hidden lifejacket is worn on, descend water to swim or sue and labour then.When the swimmer causes danger, or the lifesaver opens the charge valve of hidden lifejacket gas generator, and shakes a little during near subject, and air bag is full at once, makes the effect of hidden lifejacket performance life jacket.
2, for guaranteeing the quality of hidden lifejacket, hidden lifejacket should adopt franchise (in every county, city).Aerogenesis material and accessory are specially joined by speciality store.
3, after the hidden lifejacket inflation is used, the gas in the air bag is emitted, it is standby to reload the aerogenesis material before the use.
4, hidden lifejacket between used life, is not kept properly, in order to avoid air bag and conduit are aging, damaged.
5, hidden lifejacket will be done regular safety inspection according to the security regulations of air bag, conduit and gas generator, and as prescribed placement aerogenesis material, to guarantee the normal practicality of hidden lifejacket.
Claims (2)
1. hidden lifejacket is a kind ofly more effectively to be used to swim or the life preserver of lifesaving activity, and it is made up of inflatable bladders (being four～six independent air bags that non-return valve is housed), conduit and gas generator three parts.(other producers are provided with safety valve.) this hidden lifejacket do not causing danger or during not near subject, the life jacket air bag is in not inflated condition, volume is very little, is convenient to swimmer's swimming, and the lifesaver can be quickly near subject of salvage; When the swimmer causes danger or rescuer during near subject of salvage, open charge valve, gas generator produces enough gas, and four life saving air bags are inflated rapidly, the effect of hidden lifejacket performance life jacket.
2. hidden lifejacket according to claim 1 is characterized in that: certain air bag breakage in (1), the several air bag, other air bags still can keep full, make hidden lifejacket performance lifesaving effect.(2), the hidden lifejacket simple structure, inflation is rapidly, and is safe and practical.The safety valve of gas generator is in suitable air pressure in the time of guaranteeing the hidden lifejacket inflation.
