Problems solved by technology

[0003] The wearable life preserver is usually worn on the user's wrist or collar. In the event of a drowning accident, the user opens the high-pressure gas valve by pulling the trigger mechanism or automatically triggering by external conditions (such as immersion in water, etc.), so that the high-pressure gas is filled into the foldable life preserver. The airbag of the life preserver is used to lift the user out of the water by the buoyancy of the life preserver. This kind of life preserver can only be worn on the user's body, and the cost of use is relatively high. The force of the trigger mechanism pulls the trigger mechanism or the trigger mechanism fails, etc.) The life-saving device cannot perform the life-saving function. At the same time, some life-saving devices that rely on water immersion to trigger have high requirements for storage environment humidity, temperature and other conditions, and the equipment is prone to failure or accidental self-starting. For example, patent CN105501410A discloses a swimsuit-type anti-drowning intelligent life jacket, including a swimsuit-type life jacket body, an air bag, a trachea and a gas storage bottle. On the body of the lifejacket, there is a solenoid valve at the connection between the mouth of the gas cylinder and the trachea. The body of the lifejacket also includes an intelligent controller. The intelligent controller is connected to the drowning sensor switch on the diving goggle through a wire. , power supply module, pressure sensor, sound and light alarm, solenoid valve controller, operation display screen, GPS positioning module and satellite communication module or mobile phone communication module, the single-chip microcomputer controls the solenoid valve to open according to the time when the drowning sensor switch is intruded into the water, and the gas storage The bottle inflates the airbag, at the same time, the sound and light alarm emits sound and light, and the satellite communication module or mobile phone communication module sends out a rescue signal and the geographical position to the outside world. Distress signal, but the cost is expensive, and the popularization and use are limited
[0004] The external projectile lifesaving device refers to the life-saving equipment (lifebuoy or other buoyancy body, etc.) projected by the shore personnel to the drowning person by manpower or compressed gas to achieve the purpose of life-saving when launching a drowning accident. The cost of using this life-saving equipment It is relatively low but has a limited range of use. Generally, the life-saving equipment that is thrown by humans is usually used, and the effective throwing radius will not exceed 10m. The equipment itself is large in size. When using it, it is usually necessary to fix the equipment on the ground and set the relevant parameters of the corresponding launch orientation to achieve the purpose of lifesaving. Once a mistake occurs, it is difficult to have a second chance of recovery.

Embodiment 1

[0043] An anti-drowning life preserver, such as figure 1As shown, it includes rescue air bag 2, housing 5, gas source cylinder 7, control valve seat 8, striker 10, water-soluble tablet 12, hammer 13, spring II 14 and water-through shell 18, and the two ends of the shell 5 are opened with a Hole, one end is socketed with the rescue air bag 2, the inner wall of the housing 5 at the other end is connected with the outer wall of the control valve seat 8 through threads, and the end surface of the housing 5 and the protruding step of the control valve seat 8 are tightly fitted through a flat gasket;

[0044] The anti-reverse flow limiting valve 3 is installed in the through hole at one end of the housing 5 socketed to the life-saving air bag 2, such as figure 2 As shown, the anti-reverse flow-limiting valve is mainly composed of an inflatable seat 3.1, a spring I3.6 and a small steel ball 3.4. In the inflatable seat 3.1, there are inflatable holes I3.5, inflatable holes II3.2 and ...

Embodiment 2

[0052] An anti-drowning lifesaving device, the basic structure of which is the same as that of Example 1, the difference is that there is no protective cover outside the gas source steel cylinder, and the life saving device can also effectively play the role of lifesaving, but the safety and stability of the gas source are compared with those of the embodiment 1's life saver is inferior.

Embodiment 3

[0054] An anti-drowning lifesaving device, the basic structure of which is the same as that of Embodiment 1, the difference is that there is no anti-reverse flow limiting valve, and the lifesaving device can also effectively play the role of lifesaving, but it cannot prevent the gas from being filled into the rescue airbag and returning to the airflow path .

Abstract

The invention relates to a drowning prevention life saving device. The drowning prevention life saving device comprises a life-saving airbag, a shell, a gas source cylinder, a control valve seat, a firing pin, water-soluble tablets, a hammer, a spring II and a water-communicating shell, through holes are formed at two ends of the shell, one end of the shell is sleeved with the life-saving airbag, the other end f the shell is sealed through the control valve seat, the gas source cylinder is placed inside the shell, the shell is not in contact with the gas source cylinder, the outlet end of the gas source cylinder is connected with the control valve seat, the control valve seat is a hollow column, the control valve seat is provided with an inflatable flow hole penetrating through a hollow cavity, the control valve seat is hermetically connected with one end of the shell and the inflatable flow hole is exposed to an inner cavity of the shell, the firing pin is arranged in the hollow cavity of the control valve seat, the hammer and the firing pin are separated through the water-soluble tablets, the hammer is located in the water-communicating shell, the water-communicating shell is connected with the control valve seat, the hammer and the water-communicating shell co-compress the second spring. The drowning prevention life saving device has the advantage of low cost, is easy to carry, has excellent safety and stability, and has excellent promotion and use value.

Description

technical field [0001] The invention belongs to the field of lifesaving devices and relates to a lifesaving device for preventing drowning. Background technique [0002] The anti-drowning lifesaving device is a relatively common safety device. This device is mainly used to prevent suffocation caused by drowning when personnel accidentally fall into the water or near the water. At present, the common life-saving devices on the market mainly include wearable and There are two types of external projection. [0003] The wearable life preserver is usually worn on the user's wrist or collar. In the event of a drowning accident, the user opens the high-pressure gas valve by pulling the trigger mechanism or automatically triggering by external conditions (such as immersion in water, etc.), so that the high-pressure gas is filled into the foldable life preserver. The airbag of the life preserver is used to lift the user out of the water by the buoyancy of the life preserver. This ki...
