Abstract

The utility model relates to an emergency life saving apparatus in water, which comprises a life buoy and a life jacket. The utility model is characterized in that inner cavities of the life buoy and the life jacket are provided with disaster boxes, a hydrochloric acid pottery, calcium carbonate powers and sodium carbonate powders which are dispersedly arranged in the disaster boxes, and a box cover of each disaster box is buckled on the disaster box from the outside of the life buoy or the outside of the life jacket. The utility model adopts the structure, when a disaster occurs to a person in water, a nylon button is undrawn, the disaster box is broken up by hands, and hydrochloric acid is acutely reacted with the calcium carbonate powers or the sodium carbonate powers to generate gas. The life saving apparatus can be inflated quickly, the head of the person who is in danger floats out of a water surface, and the purpose of life saving is achieved.

Description

Emergency survival utensil in the water

The utility model relates to a kind of emergency survival utensil when drowned, and it can produce the buoyancy that drowning person's head is emerged in two seconds.

Life saving apparatus in the existing water, the air mattress when mainly containing buoy quoit, the life jacket of inflatable or rigid foam filled type and playing water etc.They have played good lifesaving effect really.But prerequisite is must prior aerification or filler.Resistance in the time of certainly will will increasing swimming like this; Hinder the arm stroke of arm, influence beginner's progress; Operation brings inconvenience in also feeding water simultaneously.In addition, because the especially long-time friction of hard life saving apparatus of life saving apparatus very easily injures skin and causes suffering, have a strong impact on movable normally carrying out in the water.Therefore a lot of people are reluctant to wear life saving apparatus.Moreover a lot of drowning persons are due to the accident, and the akinesia that has a cramp in the leg greatly when being flushed to depths or swimming as slipping in torrent also has the long-distance swimming strength not prop up or by winding such as foreign material such as pasture and water in the water ...Although above-mentioned tragedy is in successive years, these people are reluctant for preventing that this from the extremely low accident of probability taking place bind round too fat to move life saving apparatus.The broad masses that also have the flood district, the students in middle and primary schools that go for an outing, who is ready often to put the life saving apparatus of that tympanites again? as seen traditional life saving apparatus has been difficult to satisfy various contact water persons' demand.

The purpose of this utility model provide a kind of can rapid self-aerated portable water when in danger in water in the emergency survival utensil, when making unexpected the generation, person in distress's head can be emerged rapidly, avoid taking place tragedy.

The utility model is achieved in that the emergency survival utensil comprises in the water and is used for gas filed buoy quoit, life jacket.The inner chamber that is characterized in its buoy quoit, life jacket is provided with safety box, and the Paris white or the natrium carbonate powder of hydrochloric acid narrow-necked earthen jar and bulk storage is housed in the safety box.The protecting cover of safety box is outer or be buckled in outward by life jacket on the antetheca of safety box by buoy quoit, and buckles with nylon buckles.

The utility model adopts said structure, gets into danger in water, only need draw back nylon buckles (buckle closure can come off voluntarily) when meeting accident, and smashes safety box with hand, and this life saving apparatus just can be inflated rapidly, and person in distress's head is emerged, and reaches the purpose of lifesaving.

The emergency survival utensil is to utilize CaCO in the utility model water ₃(NaCO ₃)+2HCl=CaCl ₂(NaCl ₂)+H ₂O+CO ₂↑ principle realizes the fast aeration of emergency survival utensil.The emergency survival utensil comprises and is used for gas filed buoy quoit, life jacket in the water, and Fig. 1--Fig. 4 has only provided the enforcement illustration of buoy quoit, and life jacket and its are in like manner.Among Fig. 1-Fig. 7,1 is buoy quoit, and safety box 2 is fixed in the chamber of buoy quoit 1 or life jacket rear wall near the position of shirtfront.Hydrochloric acid narrow-necked earthen jar 5 and Paris white (or natrium carbonate powder) are housed in the safety box 2.Safety box 2 can be made the thin wall box that wall thickness is 0.5-1.0mm with rigid plastic, and inboard wall of cartridge has the high reinforced rib of 2mm except that antetheca, increases rigidity, the opening part loam cake grid 6 of safety box with expendable weight.Hydrochloric acid narrow-necked earthen jar 5 is the thin-walled glass container, and loam cake grids 6 in the safety box 2 of packing into after the flexible foam that available 2mm is thick wraps up are so that reactant overflows.The protecting cover 3 of safety box 2 is by being buckled in outward on the safety box 2 outside the buoy quoit or by life jacket, and for not damaging buoy quoit, protecting cover 3 domestic demands add a soft lining, buckle with nylon buckles 7.Volume size decision when the consumption of Paris white of putting in the safety box 2 (or natrium carbonate powder) and hydrochloric acid will be according to buoy quoit or life jacket aerification.Because of natrium carbonate contains the crystal water that generally can reach 10 mol wts, usage quantity is big slightly, and is difficult to accurate grasp, and price is high slightly.And use calcium carbonate also can reach requirement fully, so following narration is example with calcium carbonate.Volume is 19 cubic decimeters during as small-sized buoy quoit aerification, but from buoy quoit intensity and use two aspects safely and consider, can charge into 18 cubic decimeters carbon dioxide, and can guarantee also that like this user's is perfectly safe that (actual measurement is learnt, people's head volume is the 4.8-6.0 cubic decimeter, the proportion of the person is almost same with water, therefore as long as generation is greater than the gas of head volume in the emergency survival utensil, person in distress's head just can emerge), at this moment need restrain with calcium carbonate 82, hydrochloric acid 60 gram (as get that commercially available concentration is 37%, proportion is 1.18 hydrochloric acid, needs 162 grams).For making not residual corrosive materials behind calcium carbonate (or natrium carbonate powder) and the hydrochloric acid reaction, at buoy quoit or life jacket inner chamber bulk storage 10-30 gram Paris white or natrium carbonate powder, so that it reacts completely.For making safety box on the buoy quoit be positioned at people's front all the time, be provided with braces 4 on buoy quoit in use, braces 4 usefulness snap-fasteners and buoy quoit 1 are fixed.Adopt the buoy quoit or the life jacket of the utility model structure, have inflation simultaneously and chew, also can work as common buoy quoit use, but will notice that at this moment the protecting cover of safety box do not open, prevent misoperation.

The utility model structure is reasonable in design.When underwater work or recreation, wear the emergency survival effect that the utlity model has.Instantly before the water or when entering area, flood district, (be example for sake of convenience temporarily with the circle with the emergency survival circle.Life jacket and its in like manner repeat no more) be placed in the oxter routinely and worn braces, safety box is disposed in the front.With weighing at this moment,, owing to carefully reasonably design, except that weigh 350 grams according to same buoy quoit, do not influence the normal activity of human body basically simultaneously because of safety box is not had an effect.When meeting accident, only need draw back nylon buckles (protecting cover comes off voluntarily) and pinch the chest safety box with the fist knocking or with hand, can make glass container fragmentation in the box, when the time comes, violent chemical reaction takes place in excessive the contact with calcium carbonate or natrium carbonate of hydrochloric acid, produce a large amount of gases simultaneously in very short time, distension plays buoy quoit, realizes the emergency survival function.
