Airplane air dropping lifesaving device

Abstract

The invention relates to aircraft airdrop life-saving apparatus which is mainly composed of a waterproof windproof tarp 1, an inflatable floating bag, a safety valve 7 and a one-way air inlet valve 8, the waterproof windproof tarp 1 is arranged on the floating bag of the life-saving apparatus, the inflatable floating bag is divided into two layers of the upper inflatable floating bag 2 and the lower inflatable floating bag 3, the safety valve 7 is positioned on the floating bag of the life-saving apparatus, the one-way air inlet valve 8 is positioned at one side of the inflatable floating bag, an automatic inflation device 4 when meeting with water and a high-pressure air cylinder 5 are arranged between the upper inflatable floating bag 2 and the lower inflatable floating bag 3. The automatic inflation device 4 and the high-pressure air cylinder 5 are respectively parallelly positioned at the two sides of the inflatable floating bag. A self-drainage device 6 and a self-righting device 9 are arranged below the life-saving apparatus. The self-drainage device 6 is positioned in the middle of the space which is below the life-saving apparatus, and the self-righting device 9 is distributed on four angles below the life-saving apparatus. When a ship is in distress, lives of personnel are threatened, and a rescue ship can not arrive to the scene at the first time, the aircraft airdrop life-saving apparatus can be carried to the accident scene for implementing the airdrop by utilizing the speed advantage of a helicopter or a fixed wing aircraft. The airdrop life-saving apparatus can form a life raft through the automatic inflation by the automatic inflation device after being fallen into the water. Persons in distress can enter the life raft for waiting for the further rescue of the rescue ship, thereby wining precious time for the rescue work.

Description

[0001] Field [0002] The invention relates to an air-dropped life-saving device for automatically inflating multi-person airplanes in contact with water, which is used for lifesaving in oceans and rivers. Background technique [0003] At present, when the ship is in distress, it takes a long time for the ship of the rescue department to reach the scene of the accident, and the time required for the rescue aircraft is relatively short. However, when rescuers are rescued, only one person can be rescued by hanging rescuers at a time, which is very inefficient. Summary of the invention [0004] In order to overcome the above shortcomings, the present invention provides an aircraft airdrop life-saving device. [0005] The purpose of the present invention is achieved as follows: an aircraft airdrop life-saving device, which is mainly composed of a waterproof and wind-proof tarp 1, an inflatable floating bag, a safety valve 7, and a one-way air inlet valve 8. The waterproof and wind-pro...

[0003] At present, when a ship is in distress, it takes a long time for the ship of the rescue department to arrive at the scene of the accident, and the rescue aircraft takes a short time. However, when rescuers are rescued, only one person can be rescued at a time through suspension, which is very inefficient.
