Accompanying drawing explanation
Fig. 1 is the overboard life saving appliance structural representation of specific embodiment of the invention Portable, personal;
In figure, 1 is supply chamber, and 2 is watchband, and 3 is the first supply chamber, and 4 is the second supply chamber, and 5 is air bag, and 6 is valve, and 7 is buckle, and 8 is safety valve, and 9 is filter screen bag, and 10 is catalyst chamber, and 11 is alarm mechanism, and 12 is protective case.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and principle of work, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
As shown in Figure 1, the overboard life saving appliance of a kind of Portable, personal, comprises supply chamber 1 and watchband 2.Described supply chamber 1 is divided into two bins by bulkhead, is respectively the first supply chamber 3 and the second supply chamber 4.Second supply chamber 4 inside is spaced, be provided with a catalyst chamber 10, a filter screen bag 9 is provided with in catalyst chamber 10, filter screen bag 9 is fixed in catalyst chamber 10, second supply chamber 4 outside is provided with an alarm mechanism 11, and safety valve 8 is communicated with the first supply chamber 3 and the catalyst chamber 10 be arranged in the second supply chamber 4.Hydrogen peroxide is stored, filter screen bag 9 internal reservoir manganese dioxide in first supply chamber 3.Second supply chamber 4 side of supply chamber 1 is connected with the end of watchband 2, and relative opposite side first supply chamber 3 is provided with a buckle 7 coordinated with watchband 2 free end end.Be provided with the air bag 5 for stored-gas in watchband 2, air bag 5 is communicated with by valve 6 with the catalyst chamber 10 in the second supply chamber 4.When people falls into the water, after people applies certain pressure to safety valve 8, safety valve 8 is opened, and the hydrogen peroxide stored in the first supply chamber 3 flows to the catalyst chamber 10 that is arranged in the second supply chamber 4 and contacts with the manganese dioxide in filter screen bag 9 and generates gas.
In order to prevent under normal circumstances, false touch safety valve 8, safety valve is also provided with a protective case 12.
Manganese dioxide as added 0.3 gram with the hydrogen peroxide of 36 milliliters can produce the gas of 5 liters in 3 seconds, can be full of rapidly and allow people float the required air bag of about 4 liters.Therefore the capacity of the hydrogen peroxide stored in the first supply chamber 3 is greater than 36 milliliters, the quality of the manganese dioxide of filter screen bag 9 internal reservoir is greater than 0.3 gram, the capacity being arranged on the air bag 5 in watchband 2 is greater than 4 liters, pressing once safety valve 8, will import the hydrogen peroxide of 36 milliliters to catalyst chamber 10 in the second supply chamber 4.Persons falling in water understands anxiety after overboard, safety valve 8 may be pressed repeatedly, enter the second supply chamber 4 to prevent excessive hydrogen peroxide to react with manganese dioxide, cause producing excessive gas, may be excessive owing to filling, cause air bag 6 to be destroyed, therefore on safety valve 8, be also provided with the traffic statistics table of statistics hydrogen peroxide flow, whether the function that traffic statistics table can control safety valve 8 works, and under normal conditions, it is normal that traffic statistics table controls safety valve 8 function.When traffic statistics table statistics reaches 36 milliliters by the flow of the hydrogen peroxide of safety valve 8, traffic statistics table controls safety valve 8 malfunction, the i.e. function of hard closing safety valve 8, even if drowning people's continuous print presses safety valve 8, safety valve 8 also can not be opened again, thus ensure that the safety of air bag 6, also ensure that the normal work of the overboard life saving appliance of Portable, personal.In order to ensure that the overboard life saving appliance of Portable, personal can use by secondary, described traffic statistics table being also provided with reset button, after persons falling in water is rescued, pressing reset button, traffic statistics table will be made to control safety valve 8 function normal.In order to prevent persons falling in water by mistake by reset button in water, described reset button is provided with water level detector, and when water level detector senses water, reset button is inoperative.
As a further improvement on the present invention, drowning people is found for the ease of other people, second supply chamber 4 outside of the supply chamber 1 of the overboard life saving appliance of described Portable, personal is provided with an alarm mechanism 11, described alarm mechanism 11 comprises sound and light alarm mechanism, the storage bag of smoke generation mechanism and storage coloring agent, safety valve 8 and sound and light alarm mechanism, smoke generation mechanism and storage bag are connected by wire, when after man overboard, safety valve 8 is subject to the pressure of people, safety valve 8 controls sound and light alarm mechanism and sends sound and light alarm, storage bag discharges its coloring agent stored, smoke generation mechanism is fuming.The storage bag three of described sound and light alarm mechanism, smoke generation mechanism and storage coloring agent can be arranged on supply chamber 1 second supply chamber 4, also can optionally in three two be arranged on supply chamber 1 second supply chamber 4, can also optional one be arranged on supply chamber 1 second supply chamber 4, have six kinds and installation method be set.
Conveniently succour persons falling in water and can not disturb the operation of the regular event of persons falling in water, the overboard life saving appliance of Portable, personal is fixed in the waist of personnel, arm or wrist by watchband 2.
The overboard lifesaving method of a kind of Portable, personal, step one, overboard for Portable, personal life saving appliance is worn by the personnel that wear; Step 2, after people is overboard, applies pressure to safety valve 8; Step 3, safety valve 8 is opened, and the hydrogen peroxide stored in the first supply chamber 3 enters catalyst chamber 10 in the second supply chamber 4; Step 4, traffic statistics table statistics is by the flow of the hydrogen peroxide of safety valve 8, and when the flow added up reaches 36 milliliters, traffic statistics table controls safety valve 8 malfunction, i.e. the function of hard closing safety valve 8; Step 5, the hydrogen peroxide entering catalyst chamber 10 produces a large amount of oxygen through the surface of filter screen bag 9 and the manganese dioxide generation chemical reaction of its internal reservoir; Step 6, the oxygen that step 5 produces enters air bag 5 by valve 6, and air bag 5 is expanded and produces buoyancy, personnel are worn in relief; Step 7, safety valve 8 controls sound and light alarm mechanism and sends sound and light alarm, and storage bag discharges its coloring agent stored, and smoke generation mechanism is fuming; Step 8, after persons falling in water is rescued, presses reset button, and the overboard life saving appliance of Portable, personal can reuse.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
