Embodiment 1

[0017] Such as figure 1 , figure 2 , The annular airbag rapid inflation device includes a fastening screw 1, a top cover 2, a top cover sealing ring 3, a gas generator 4, a bottom sealing ring 5, a buffer chamber 6, and an air bag 7.

[0018] Two gas generators 4 are installed inside the buffer chamber 6, and are connected with the top cover 2, the top cover sealing ring 3, and the bottom sealing ring 5 through fastening screws 1 to form an internal airtight cavity, and the air bag 7 is connected through its own ventilation pipe, The gas generator wire passes through the bottom wire hole to connect to the external signal source.

[0019] The gas generator 4 mainly includes an electric igniter, a double-base propellant charge, and metal shell parts. The electric igniter is an electric starting ignition device, which is used to ignite the double-base propellant charge, and the ignition current is 1A. The double-base propellant charge is used to produce energy from gas. The c...

Abstract

The invention discloses an annular airbag quick inflation device, which is composed of a fastening screw (1), a top cover (2), a top cover sealing ring (3), a gas generator (4), a bottom sealing ring(5), a buffer chamber (6) and an airbag (7). The buffer chamber (6) is connected with the airbag (7). The two gas generators (4) are fixed in the buffer chamber (6) and are provided with a top cover (2), which is tightly connected with the buffer chamber (6) through fastening screws (1). A lead hole is arrange at that bottom of the buffer chamer, and the gas generator (4) is connected with an external signal source through the lead, a large amount of clean gas is generated after the electric signal is receive and excited, and the gas is cooled and decompressed through the buffer chamber (6), and the gas enters an air bag for inflation after removing impurities. The invention has the advantages of simple structure, light weight, quick response, all-weather reliable operation, and is a device capable of rapidly inflating an air bag through electric signal control.

Description

technical field [0001] The invention relates to an annular airbag inflation device, which is mainly suitable for realizing rapid inflation of an annular airbag by using an electric signal remote control device to work. technical background [0002] With the development of society and changes in the international situation, whether in the field of national defense weapons or economic development, the protection of ocean waters and the exploration of water resources have become more and more important. Various underwater and surface weapons and detection platforms have also emerged as the times require. When some detection platforms work, they need to rise from the diving state to the water surface for floating, and a carrier is needed to help realize the process of surfacing from the water to the water surface. After inflating the annular airbag in the water, it uses buoyancy to drive the load to float to the water surface, which is a solution for underwater objects to rise ...
