Abstract

The utility model relates to a portable life buoy, which belongs to the technical field of life buoy. The portable life buoy solves the problem that the existing life buoy can not be carried about, and ensures the personnel safety of operation at sea. Because the portable life buoy can preset the depth of falling into water, the worries of personnel operation at sea and visitors swimming in water can be solved. The utility model is mainly composed of an exterior package body, a folding life buoy body, an automatic control valve which is arranged on the life buoy body, chemical agentia, etc. The utility model is mainly used on water, and can be used for the personnel operation at sea and various big, middle and small bathing beaches.

Description

Portable life buoy

The utility model relates to the technical field of buoy quoit.

At present, big, the medium and small ship of each of operation all has buoy quoit on the water, and they generally all are to be suspended on the hull, when personnel were drowned, just throwing went down to give first aid to, and therefore the time of delay is long, and situation waterborne is very complicated, often the purpose of out of reach rescue.Such as, drowned as personnel, nobody knows, though or know, throw buoy quoit down, but when meeting current and too suddenly waiting other unforeseen circumstances, can meet accident unavoidably; For another example, ship suffers accident, and when shipwreck or shipwreck, the ship's staff will be helpless, and can not each personnel can both obtain that benzene heavily, is hung on buoy quoit limited on the hull, in this case, just has many personnel of having and experiences misfortunes.In addition, in various bathing beaches etc. during swimming, if be with cane---during water wing, some disppointment unavoidably, if but be not with, do not quite trust rather.

At these situations, the purpose of this utility model has designed a kind of in light weight exactly, folding can carrying, and under the drowning degree of depth situation that presets voluntarily, the buoy quoit of the function of have automatic expansion expansion, floating automatically.

The utility model content mainly is made up of the external packing body of a band window and collapsible lifesaving rubber ring of placing within it.On the lifesaving rubber ring, be provided with automatic controlling valve and preset depth marker, with and in-to-in chemical reaction chamber and chemical agent.For the ease of carrying, also being provided with the nose ear on the rubber circle body, to be exposed to external packing external.

The utility model has solved the drawback that former buoy quoit can not be carried, and has guaranteed operation at sea personnel's personal safety, owing to can preset the drowning degree of depth, has therefore also solved the trouble and worry when normally swimming underwater work personnel and visitor.It can be used in waterborne, underwater work personnel widely, and each large, medium and small swimming place.

Now accompanying drawing is made brief description

Existing detail illustrates its structural principle and embodiment.As shown in drawings, ［ 4 ］ are the external packing bodies, and window curtain ［ 1 ］ is arranged thereon, check apron ［ 6 ］, snap-fastener ［ 5 ］; ［ 11 ］ be the lifesaving rubber ring, automatic controlling valve ［ 8 ］ is arranged thereon, catalyst chamber ［ 12 ］ and nose ear ［ 15 ］; Valve seat ［ 17 ］ is arranged on automatic controlling valve ［ 8 ］, valve gap ［ 18 ］ by screw thread be connected with valve seat ［ 17 ］, between valve seat ［ 17 ］, valve gap ［ 18 ］, valve block ［ 9 ］, valve spring ［ 13 ］, ［ 14 ］ are arranged; And be engraved on the depth of water scale mark ［ 2 ］ on the valve seat ［ 17 ］ in addition and be engraved on depth of water mark line ［ 3 ］ on the valve gap ［ 18 ］, chemical agent ［ 10 ］ is arranged in catalyst chamber ［ 12 ］ and go out vent hole ［ 16 ］.［ 7 ］ be annular water inlet on the valve gap ［ 18 ］.

When normal circumstances, the utility model utilizes nose ear ［ 15 ］ to be through in the waist-belt, carry, the available snap-fastener of window curtain ［ 1 ］［ 5 ］ on it closes, also the snap-fastener left-hand thread of available behind is on it, utilize check apron ［ 6 ］ that folding buoy quoit ［ 11 ］ is kept off outside in the packaging body, in case it is drowned, when human body arrives the depth of water that presets, exterior river acts on the valve block ［ 9 ］ by the annular opening ［ 7 ］ that covers outward, overcome the spring force of preset, move after making valve block ［ 9 ］, river enters the valve block hole by annular opening ［ 7 ］, arrive the valve spring seat hole on the valve seat ［ 17 ］, entered catalyst chamber ［ 12 ］, chemical agent ［ 10 ］ carries out rapid generated reactive gas with water, owing to go out vent hole ［ 16 ］ on the catalyst chamber, because of folding reason, the through hole cross section is very little, therefore the very fast rising of chamber pressure, pressed gas acts on the bigger valve block of area, with spring force lump together overcome very soon bear hydraulic pressure on the less area valve block, make valve block ［ 9 ］ close water inlet, catalyst chamber ［ 12 ］ continues reaction under surplus liquid, expand, at this moment, the air outlet hole mouth sectional area increases, pressed gas is constantly inflated to folding rubber circle body by the both sides air gate in a steady stream, because the people side hampers the inside expansion of rubber ring, so expanding gas just produced outside reaction thrust at both sides curtain place, makes that the buoy quoit in the middle part of the external packing body window is at first outwards heaved, and step by step folding lifesaving circle body emitting automatically from level to level, at this moment, the drowning person has reached the purpose of rescue as long as can instead be placed on the health once being with have gentle hands is light.

The employed external packing body of the utility model ［ 4 ］ available artificial leather etc. is made, the packaging body of making must have certain shape freezability, chemical agent ［ 10 ］ can adopt sodium peroxide (Na202) powder, valve spring ［ 13 ］, ［ 14 ］ available 65Mn steel, valve seat, valve gap can be made with alloy in lightweight attractive in appearance, valve block can be better with resistance to abrasion, also high-carbon steel such as 65Mn make elasticity preferably, to cooperate precision between valve gap ［ 18 ］ and the valve block ［ 9 ］, the size of the water inlet aperture of valve body should guarantee catalyst chamber boost close before, charge into enough flooding quantitys, guarantee that all chemical agents all participate in reaction; Folding lifesaving circle body can adopt the canvas material pressing of one-side band rubber to form, the utility model is easy to maintenance, if the time is longer, inside penetrates water vapour, and when chemical agent lost efficacy, inside was bound to produce gas and heaves to some extent, pass through annular opening, push up inner valve block and emit gas, can back out valve gap if necessary, add a spot of sodium peroxide (Na202) powder again and get final product.
