Abstract
The utility model discloses a drowning self-rescuing device, which comprises an air bag (1), an air generator (2) communicated with the air bag (1) through a conduit (3), and a pressure switch (4) arranged on the conduit (3). The drowning self-rescuing device has small volume at ordinary times; and when being tied on a person, the device is not separated and does not affect swimming or water activities. In danger, when a swimmer is sunken to an underwater depth of 2 meters, the pressure switch (4) is automatically switched on by the set pressure, the high-pressure liquid air in the air generator (2) is quickly conveyed to the air bag (1) by the conduit (3) in short time, and the air bag (1) is quickly expanded to increase the buoyancy so as to assist the drowning person in surfacing and realize self-rescuing.
Description
Technical field
The utility model relates to a kind of life preserver, specifically a kind of drowned self-help apparatus with automatic lifesaving function.
Background technology
The drowning lifesaving product that generally uses is buoy quoit and life jacket at present.They only are applicable to complete prepared occasion, are not easy to carry.The child at the nearly side of a pond, rivers lake, pupil also can not wear life jacket all day and be with buoy quoit for anti-drowning, and can feel very inconvenient like this; The swimmer wears life jacket or is being with buoy quoit swimming, can make the swimming activity be subjected to certain restriction, influence the effect of swimming activity, all dislikes using, but in case occurs that trick is knotted or other unforeseen circumstances and drowning with regard to danger close.Therefore, the thing died from the water of the person of being able to swim is much.
The utility model content
The technical problems to be solved in the utility model provide a kind of normal condition lower volume very little, wear on the health or when swimming all very easily, drowned self-help apparatus with automatic lifesaving function.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: drowned self-help apparatus includes air bag, by the gas generator that conduit communicates with air bag, is installed in supravasal pressure switch.
High-pressure liquid gas is housed in the described gas generator.
When bearing 0.2 bar pressure under water, described pressure switch opens automatically.
Drowned self-help apparatus ties up on the person in that volume is very little at ordinary times, can not separate, and can not influence swimming and water activity.When in danger, when the swimmer sinks to certain depth, the pressure that pressure switch is set and after opening automatically, in very short time, the high-pressure liquid gas in the gas generator is transported to air bag by conduit rapidly, and air bag is expanded rapidly, increase buoyancy, help the drowning person to emerge, realize saving oneself.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, drowned self-help apparatus includes air bag 1, by the gas generator 2 that conduit 3 communicates with air bag 1, is installed in the pressure switch 4 on the conduit 3.Drowned self-help apparatus ties up on the person in that volume is very little at ordinary times, can not separate, and can not influence swimming and water activity.When in danger, when the swimmer sinks under water 2 meters the degree of depth, the pressure that pressure switch 4 is set (0.2 bar pressure) will be opened automatically, in very short time, high-pressure liquid gas in the gas generator 2 is transported to air bag 1 by conduit 3 rapidly, and air bag 1 is expanded rapidly, increases buoyancy, help the drowning person to emerge, realize saving oneself.
Claims (3)
1. a drowned self-help apparatus includes air bag (1), it is characterized in that: also include the gas generator (2) that communicates with air bag (1) by conduit (3), be installed in the pressure switch (4) on the conduit (3).
2. drowned self-help apparatus according to claim 1 is characterized in that: described gas generator is equipped with high-pressure liquid gas in (2).
3. drowned self-help apparatus according to claim 1 is characterized in that: open automatically when described pressure switch is born 0.2 bar pressure under water.
