Embodiment

[0017] Example: see figure 1 , 2 , the knapsack emergency life-saving device of this embodiment includes a hollow non-closed spherical airbag 1 and an air supply device 2 in the inner cavity of the airbag. The airbag body is provided with a plurality of ventilation holes 4 which communicate the inner cavity of the airbag with the outside world.

[0018] image 3 , 4 As shown, the gas supply device 2 includes two high-pressure gas storage cylinders 6. The high-pressure gas storage cylinders 6 are connected to the airbag's inflation nozzle 3 through a pipeline, and an air pressure gauge 7 and a control valve are arranged on the pipeline.

[0019] In the specific setting, two high-pressure gas storage cylinders 6 are arranged in parallel, and the two high-pressure gas storage cylinders are connected to the airbag's inflation nozzle 3 through a parallel pipeline, and a mechanical valve 8 is provided on one branch of the parallel pipeline; An electronically controlled valve 9 i...

Abstract

The invention discloses a backpack type emergency survival device which comprises a hollow non-closed spherical airbag and an air supply device in an airbag, wherein the air supply device charges a sandwich of the airbag by a charging connector on the inner wall of the airbag; and the airbag body is provided with a plurality of ventilation holes through which the inner cavity of the airbag is communicated with the outside. The emergency survival device has simple structure, is easy to carry, can be used as survival equipment under the emergency condition and is widely applied to aloftwork operation, sailing, exploration, earthquake, flood and other natural disaster environments.

Description

Technical field: [0001] The invention relates to a life-saving device, in particular to a backpack-type emergency life-saving device which can protect the user and slow down the injury under the emergency situation of strong impact or when falling into the water, so as to play a life-saving role. Background technique: [0002] The existing high-altitude emergency life-saving equipment often adopts slow-drop wire rope or gliding method, which requires a long preparation time before use, and has a fixed position, so it is difficult to really play its due role in an emergency. In an emergency, due to the panic in the environment, it is difficult for the user to calmly follow the requirements of the equipment in a short period of time, which will not only delay the best time for escape, but may also cause greater bodily harm to the user. [0003] Among the surface emergency lifesaving equipment, the most common are life rafts and life jackets. Life rafts cannot withstand strong...
