Problems solved by technology

[0002] The existing automatic inflatable life-saving devices in water use calcium carbide and water to react to produce acetylene to inflate. Although the reaction is fast, acetylene is a highly flammable gas and has certain dangers; At the same time, the gas will also generate a lot of heat, which has higher requirements on the device and is more dangerous; there is a principle that the volume of oxygen or carbon dioxide in the liquid state becomes gaseous t

Embodiment 1

[0018] Such as figure 1 and figure 2 As shown, a diameter of 45cm is an elastic plastic ring 1 with a gap, which is hollow inside, and a buckle 2 is respectively provided at its two ends, and these two buckles 2 are mutually locked to make the elastic plastic ring 1 It becomes a closed circle, a pressure sensor 4 is provided on a buckle 2, and a C-shaped airbag 3 is wrapped around the elastic plastic ring 1. The C-shaped airbag 3 is a C-shaped with a gap, and its two ends are sealed and fixed. At both ends of the elastic plastic ring 1, a cut-off valve (not shown in the figure) connecting the inner space of the elastic plastic ring 1 and the external C-shaped air bag is provided at the end provided with a pressure sensor. The pressure sensor on the buckle 4 can control the opening and closing of the stop valve; the cavity in the elastic plastic ring 1 stores difluorodichloromethane and monofluorotrichloromethane with a volume ratio of 1:1.1, and the C-type airbag is coated w...

Embodiment 2

[0021] Such as image 3 As shown, the present invention includes a elastic plastic ring 1 with a diameter of 45 cm and a gap, which is hollow inside, and is provided with a buckle 2 at both ends, and the two buckles 2 can be locked or disassembled. , the elastic plastic ring 1 can be made into a closed ring, and a C-shaped airbag 3 is wrapped around the elastic plastic ring 1. The C-shaped airbag 3 is a C-shaped with a gap, and its two ends are sealed and fixed on the elastic plastic ring 1 At the two ends of the elastic plastic ring 1, a cut-off valve (not shown) connecting the internal space and the external C-shaped airbag is provided. This cut-off valve is controlled by a string 5, and the elastic plastic ring 1 is Difluorodichloromethane and monofluorotrichloromethane with a volume ratio of 1:0.9 are stored in the cavity of the airbag. The C-type airbag is coated with fluorescent paint, which is convenient for finding people who fall into the water at night.

Abstract

The invention relates to an underwater lifesaving device, in particular to an underarm automatic inflation life buoy. The underarm automatic inflation life buoy comprises a hollow elastic plastic ring (1) with a notch, wherein two clamp buckles (2) are respectively arranged at two ends of the notch, a C-shaped air sac (3) sleeves the exterior of the hollow elastic plastic ring (1), two ends of the C-shaped air sac (3) are respectively fixed at two ends of the elastic plastic ring (1) in seal mode, a stop valve is arranged at one end of the elastic plastic ring (1), and communicates an inner space of the elastic plastic ring (1) with the C-shaped air sac (3), dichlorodifluoromethane and fluoro trichloromethane are placed in the elastic plastic ring (1), and a volume ratio between the dichlorodifluoromethane and the fluoro trichloromethane is 1:0.8-1.2. The underarm automatic inflation life buoy has the advantages of being good in safety, quick to inflate, and low in cost, and can be widely popularized and used by swimmers.

Description

technical field [0001] The invention relates to a lifesaving device in water, in particular to an underarm automatic inflatable lifebuoy ring. Background technique [0002] The existing automatic inflatable life-saving devices in water use calcium carbide and water to react to produce acetylene to inflate. Although the reaction is fast, acetylene is a highly flammable gas and has certain dangers; some use gunpowder, which burns and emits a large amount At the same time, the gas will also generate a large amount of heat, which has higher requirements on the device and is more dangerous; there is a principle of using liquid oxygen or carbon dioxide to change the volume of gaseous oxygen or carbon dioxide to provide buoyancy, or It uses high-pressure gas to change low-pressure gas to inflate, but these two methods have very high requirements for gas storage devices, and generally require high-strength gas storage devices, which increases the weight and cost of life-saving devic...
