Problems solved by technology

For example, when the person who fell into the water floats on the water using portable life-saving equipment, he lacks effective tools to form a connection with the person in the safe zone, so that the person in the safe zone can pull him to the safe zone; After the equipment floats on the water, he lacks effective tools to help other drowning persons nearby; for another example, when someone falls into the water, it is difficult for rescuers to pass the lifesaving equipment to the drowning pe

Embodiment 1

[0029] Such as Figure 1-6 As shown, a portable water lifesaving device 1 includes a casing 2, the casing 2 is made of hard metal material, the casing 2 is provided with an airbag 3, and a gas generating device 5 connected to the airbag 3 through a conduit 6, and also includes a control gas generating device 5. The inflation switch 12 of the device 5, when the inflation switch 12 is triggered, the gas generating device 5 is opened to inflate the airbag 3 through the conduit 6; the casing 2 is divided into a first casing 21 and a second casing 22, and the first casing 21 and the second casing 22 are respectively connected to the One end of the airbag 3 is connected, and there is a connecting piece between the first shell 21 and the second shell 22. The value of the connection strength produced by the connecting piece is smaller than that produced by the airbag 3 on the first shell 21 and the second shell 22 when it is inflated. The value of the tensile force. When the airbag 3...

Embodiment 2

[0042] Such as Figure 1-9 As shown, a plurality of portable water lifesaving devices 1 can be connected by means of the lock 9 or the ejection lock 4 after being inflated, and various connections can be formed according to the position of the lock 9 or the elastic lock 4 on the shell. Mode to adapt to different life-saving situations.

[0043] The gas generating device 5 is also provided with a gas generating quantity control device 11 , which can control the quantity of gas generated by the gas generating device 5 . Operating the inflation switch 12 can control the gas generating quantity control device 11, so that the gas generating device 5 can inflate the air bag 3 according to the set quantity. The inflation mode is divided into 3 levels. Short press the inflation switch once, then one-third of the total amount of gas will be injected into the airbag, and a total of three short presses can be made; long press the inflation switch to fill it up at one time. The gas gene...

Abstract

The invention provides a portable overwater lifesaving device. The portable overwater lifesaving device comprises a shell, an inflation switch, a launching lock catch, a rope, a launching device and arope recycling device and is characterized in that an air bag and an air generating device are arranged in the shell, the air generating device is connected with the air bag through a guide pipe, oneend of the rope is connected with the launching lock catch, the other end of the rope is connected with the shell, and the launching device can launch the launching lock catch; the rope recycling device can recycle the rope and allow the launching lock catch to approach the shell; the shell and/or the air bag is provided with lock catches, the lock catches can be connected together, and the lockcatches can be connected with the launching lock catch. By arranging the launching lock catch, the rope, the launching device, the rope recycling device, the lock catches and the like, the portable overwater lifesaving device can achieve self-rescuing and mutual-assistance rescuing during lifesaving.

Description

technical field [0001] The invention relates to a water life-saving device, in particular to a portable water life-saving device. Background technique [0002] According to the World Health Organization, an estimated 360,000 people died from drowning in 2015 alone. Drowning is often caused by emergencies, including problems with one's own physical condition, accidental falling into the water, encountering floods, encountering shipwreck, etc. When victims encounter danger, they lack effective rescue tools. Large, heavy, single function and other shortcomings. In order to overcome these defects, a series of portable water life-saving devices have been developed, such as Chinese patent CN105460181B discloses a kind of portable water life-saving device, utilizes a compressed air tank to inflate an inflatable life buoy; Chinese patent CN106043628B discloses a portable water life-saving ball, The elastic bag is inflated by using the gas and foam generated by the reaction of the ...
