Abstract

The utility model discloses a water body-protector which comprises an outer shell capable of opening and closing and a reed. The utility model takes metal fasteners and wet broken objects to bind, and the outer shell is provided with an airbag which forms two chambers by multiple kinking. Chemicals, which are mixed to sharply generate chemical reaction and quick release a lot of gas, are arranged in the chamber; after the air bag is filled with the gas, the air bag expands to produce buoyancy to make the people who fall into water save themselves. The body-protector has the advantages of simple structure, easy operation and portability as an ornament for small size; the utility model is a safety protection appliance which is suitable for people working and campaigning on water, tour on waterway, original learning swimming, and falling into water for children when the children play; the utility model does not affect freedom of action of water living.

Description

Water body-protector

The utility model relates to safety method field, particularly aquatic life-saving equipment.

For operation at sea personnel, water activity personnel, beginning swimmer, the child that travels outdoors, all might unexpected fall into water and cause danger, as carry swimming lifesaving circle and so on lifesaving appliance, seem very inconvenient, therefore, be sought after a kind of safety precaution utensil that can tie with oneself, personal protection arrangement waterborne is exactly a kind of portable lifesaving appliance of being dying, it utilizes the mixing of two kinds of chemical substances and chemical reaction sharply takes place, discharge a large amount of gases rapidly and be full of air bag, generation buoyancy rises the people and obtains rescue.But the flak jacket apparatus structure complexity waterborne of prior art need possess gas generator, just can make gas be full of air bag by valve or switch manipulation and produce buoyancy, because complex structure, just can not do very small and exquisitely, as the safety precaution utensil of tiing with oneself, be blemish in an otherwise perfect thing really.

The purpose of this utility model be to overcome the defective of prior art and provide a kind of structure simpler, implement easily, volume is small and exquisite, the personal protection arrangement waterborne of being more convenient for carrying.

The utility model personal protection arrangement waterborne comprises a shell, this shell is involuted by two halves, wall is provided with a reed within it, the opening and closing place of shell is fixing by metal screw thread and moist breaking matter wrapping, folding dead front type air bag is housed in the shell, air bag forms the chambers of two storage chemical substances through kinking repeatedly, automatically opening air bag when shell is also stretched, chemical substance in two chambers is just directly mixed sharply generation chemical reaction in capsule, discharge a large amount of gases rapidly and make airbag inflation produce buoyancy, the drowning people is saved oneself in time out of danger.

Advantage of the present utility model is the undesirable gas producer, chemical substance is directly at the air bag internal reaction, therefore also save valve, switch and so on part in addition, therefore structure is simple especially, implements easily, and volume can be done very small and exquisitely, can be used as ornament and tie any part the people, do not influence alerting ability movable in people's water, do not hinder operation at sea, water activity personnel's freedom of action yet.

Description of drawings.

Fig. 1 is the utility model structure cutaway view.

Fig. 2 is № 1 a shell expansion drawing.

Do following describing in further detail in conjunction with above-mentioned accompanying drawing embodiment.

The two halves that the shell (1) of personal protection arrangement waterborne (seeing Fig. 1-2) is become to have ornamental value by hard plastic injection molding, but and by the nonrigid plastic doubling folding that fuses, the opening and closing place is fixing by metal screw thread (3) and moist breaking matter (2) wrapping, metal screw thread (3) can be copper wire or galvanized wire, moist breaking matter (2) can be paper tape or earth, one strip reed (6) is located at shell (1) inwall, also can fix and freely to be provided with, when paper tape or earth are subjected to wet molten having no progeny, the packing force that reed (6) overcomes metal screw thread (3) launches shell (1).

Folding dead front type air bag (5) is housed in the shell (1), the material of air bag is made by resistant to corrosion flexible material such as rubber or blowing, air bag (6) forms two chambers through kinking repeatedly, preferably smear french talc at kinking place, air bag inwall, avoid adhesion, be equipped with in two chambers after two kinds of mixing can attack chemical substance (8), this chemical substance (8) can be the combination of sodium bicarbonate and liquid citric acid, can be the combination of ammonium hydrogencarbonate and hydrochloric acid also, can produce a large amount of CO after the mixing ₂Gas expands air bag (5).Spring (4) and plastic pipe (7) also are housed respectively in two chambers, and its effect is that chemical substance (8) is fully mixed, and air bag (5) is had support, and can not stick together and influences the effect of chemical reaction.

The proportioning of chemical substance (8) is an example with sodium bicarbonate and citric acid: get sodium bicarbonate 15 grams, citric acid 23 grams add suitable quantity of water, can produce 4 liters of gases after reaction, are applicable to that child saves oneself.As get sodium bicarbonate 18 grams, citric acid 27 grams add suitable quantity of water, can produce 5 liters of gases after reaction, can save oneself for the adult.

This personal protection arrangement can install the band rope on air bag (5), so that tie in waist or front, and total weight 75 grams～150 grams.

When operation at sea personnel or water activity personnel or child travel outdoors fall into water after, moist breaking matter on the personal protection arrangement (2) is met water-solubleization, metal screw thread (3) unclamps, shell (1) launches under reed (6) effect, the air bag (5) of interior dress launches rapidly, under air bag (5) inner spring (4) effect, two kinds of chemical substances (8) fully hybrid concurrency are given birth to reaction, thereby produce a large amount of gases and be full of whole osed top air bag (5), and continue to make it to expand into certain volume, make the carrier in time out of danger or meet other people and fall into water and rescue human thereby produce cooresponding buoyancy.

Claims

1, a kind of personal protection arrangement waterborne by shell (1), may be folded on the dead front type air bag (5) in the shell (1) and the chemical substance (8) that air bag (5) expands is formed, is characterized in that:

A. described shell (1) is involuted by the two halves of the one that links to each other, and the opening and closing place is fixing by metal screw thread (3) and moist breaking matter (2) wrapping;

B. shell (1) inwall is provided with a reed (6);

C. air bag (5) is along repeatedly kinking and constitute two chambers of any part, and the chemical substance (8) that can produce gas after the mixing is housed in respectively in two chambers.

2, personal protection arrangement waterborne as claimed in claim 1 is characterized in that described chemical substance (8) can be the combination of sodium bicarbonate and liquid citric acid, also can be the combination of ammonium hydrogencarbonate and hydrochloric acid.

3, personal protection arrangement waterborne as claimed in claim 1 is characterized in that in two chambers of air bag (5) plastic pipe (7) and spring (4) being housed respectively also.
