Abstract
A kind of inflated water lifesaving appliance.It comprises the compressed air source unit that has electric igniter with the buoyancy aid bonded assembly, it is characterized in that this compressed air source unit has one and connects the solid type gas generator of this buoyancy aid and the drowning signal switch of control charge operation.After operation at sea personnel or occupant were not intended to fall into water, this lifesaving appliance (less than 4 seconds) was rapidly finished gas replenishment process automatically, and personnel are held out the water surface.The present invention is simple in structure, and cost is low; Transportation, safe and reliable; No matter under high temperature or cold environmental conditions, aeration speed is fast and stable; Be widely used under the various climatic conditions in the river, the usefulness of river, lake, sea rescue.
Description
The present invention relates to a kind of improved aquatic life-saving equipment, particularly a kind of inflated water lifesaving appliance.
Compressed air source unit in the aquatic life-saving equipments such as existing inflatable life jacket, buoy quoit and liferaft is normally by CO
2The mechanism of the control charge operation of high-pressure gas bottle and more complicated forms.When operation at sea personnel or occupant were not intended to fall into water, this compressed air source unit was just finished the gas replenishment process to buoyancy aid in the lifesaving appliance, and personnel are held out the water surface.This lifesaving appliance contrast on-inflatable formula aquatic life-saving equipment, its advantage is: easy to use and lifesaving effect is better etc., but owing to adopts CO
2High-pressure gas bottle is as source of the gas, thereby has following shortcoming: (one) aeration speed is influenced by environmental temperature.Not only aeration speed descends at low temperatures, and because the swelling heat absorption of high pressure gas so produce " freezing " phenomenon at exhausr port, stops up exhausr port, the purpose of out of reach lifesaving; (2) run into the danger that high temperature and fierce bump have blast; (3) gas cylinder is to utilize " firing pin " to pierce through gas cylinder to seal realization to the gas filed form of buoyancy aid, the structure more complicated of its compressed air source unit, and technical requirements and cost are also higher.
The objective of the invention is for a kind of improved inflatable water life saving device is provided.It replaces existing compressed air source unit with solid type gas generator and drowning signal switch, thereby can overcome the existing inflatable shortcoming of rescuing device waterborne effectively.
The present invention is achieved in that inflated water lifesaving appliance, comprise the compressed air source unit that has electric igniter with the buoyancy aid bonded assembly, it is characterized in that this compressed air source unit has one and connects the solid type gas generator of this buoyancy aid and the drowning signal switch of control charge operation.When operation at sea personnel or occupant are not intended to fall into water, the signal switch that falls into water meet water just rapidly (less than 0.1 second) produce electric signal, start electric igniter.Heat at electric igniter excites down, by the solid gas forming agent in the solid type gas generator chemical reaction takes place rapidly, produces lot of pure and non-poisonous nitrogen, just with the buoyancy aid inflation, personnel is held out the water surface (less than 4 seconds).Drowning signal switch is according to the characteristic of the difference of air and water conductive resistance, utilizes silicon control as conductive switch, can finish gas replenishment process automatically to reach after lifesaving appliance falls into water, and bubbles through the water column.
The present invention compared with prior art, its distinguishing feature is to adopt the solid type gas generator as source of the gas, and is influenced by ambient temperature little, aeration speed is fast and stable, even become gas under cryogenic conditions, still can satisfy the requirement of fast aeration; Internal pressure was low (less than 6kg/cm when gas generator became gas
2), safe and reliable; Gas is pure, nontoxic, non-corrosiveness; The signal switch that falls into water lags behind little, and reliability is big; Whole apparatus structure is simple, and cost is low.The present invention is widely used under the various climate environment conditions in the river, the usefulness of river, lake, sea rescue.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the inflated water lifesaving appliance scheme drawing that proposes according to the present invention.
The present invention is described in further detail below in conjunction with accompanying drawing.
This lifesaving appliance comprises a buoyancy aid (6), and buoyancy aid (6) is chained together with the drowning signal switch three of solid type gas generator and control charge operation.
The solid type gas generator is made up of electric igniter (1), solid gas forming agent (2), filtration cooling vessel (3) and housing (4) in the accompanying drawing.When the bridge wire connection energize of electric igniter (3), electric igniter (1) just produces enough heats and excites solid gas forming agent (2), and solid gas forming agent (2) is made up of oxidizer, deoxidation compound, auxiliary agent 1 and auxiliary agent 2, when oxidizer is Fe
2O
3Or KNO
3, deoxidation compound is NaN
3Or NH
4NO
2, auxiliary agent 1 is MnO
2With auxiliary agent 2 be SiO
2The time, become the gas best results.The nitrogen that solid gas forming agent (2) is generated is by filtering the filtration and the cooling of cooling vessel (3), at last by with buoyancy aid bonded assembly exhausr port (5) inflation buoyancy aid, lifesaving appliance is bubbled through the water column.
Drowning signal switch is an electronic switch.In the time of in two probe A of this switch and the B encroached water, because the electric conductivity of water is greater than air, promptly produce an electric signal and after amplifier (7) amplifies, trigger silicon control (8), make silicon control (8) conducting, thereby the loop that power supply (9), electric igniter (1) bridge silk, calling help signal lamp (10) and silicon control (7) are formed constitutes path, makes electric igniter (1) igniting.Igniting back axle silk blows, and power supply is only given calling help signal lamp (10) power supply.Like this, just, realized the automatic gas replenishment process of buoyancy aid.In the accompanying drawing on the electronic switch and connect a hand switch (11).When the electronic switch et out of order, can utilize hand switch (11) to start electric igniter (1), the same gas replenishment process of realizing buoyancy aid has improved the lifesaving reliability greatly.
Claims (6)
1, a kind of inflated water lifesaving appliance, comprise the compressed air source unit that has electric igniter (1) with buoyancy aid (6) bonded assembly, it is characterized in that this compressed air source unit has one and connects the solid type gas generator of this buoyancy aid (6) and the drowning signal switch of control charge operation.
