Inflatable life-saving backpack for marine peril escape

Abstract

The invention discloses an inflatable life-saving backpack for marine peril escape. The inflatable life-saving backpack comprises a backpack box body, a power cavity is formed in the backpack box body, an unfolding cavity located on the upper side of the power cavity is formed in the backpack box body, a composite power device is arranged in the power cavity, an auxiliary raft unfolding device which is positioned on the upper side of the composite power device and is symmetrical front and back is arranged in the unfolding cavity, auxiliary raft descending devices are correspondingly hinged toconnecting rods on the front side and the rear side, a main raft unfolding device located on the right side of the auxiliary raft unfolding device is arranged in the unfolding cavity, and an inflationdevice located on the lower side of the main raft unfolding device is arranged in the power cavity. According to the inflatable life-saving backpack, a propeller device can be used for enabling a person in distress to quickly free an accident sea area so as to be prevented from being influenced by vortex waves generated by a sunken ship; and an automatic inflation device can enable the life-saving backpack to become a small-sized life raft, so that the person in distress is prevented from being soaked in water for a long time, and then the survival rate of the person in distress in distress is effectively improved.

Description

technical field [0001] The invention relates to the technical field of shipwreck lifesaving, in particular to an inflatable lifesaving backpack for fast escape from shipwreck. Background technique [0002] A shipwreck is a distress caused by a ship encountering a natural disaster or other accidents at sea. There are many types of accidents that cause a shipwreck, such as ship grounding, grounding on rocks, collision, fire, explosion, ship disappearance, and damage to the main engine and equipment of the ship that cannot be repaired by itself. Ships out of control, etc. Shipwrecks can cause huge losses to life and property. There are many shipwrecks in the world every year. At present, the main escape methods in case of shipwrecks are: put on life jackets, use lifelines, life ladders to escape into the water or put on life jackets Jump directly into the water to escape, or board a lifeboat (raft) to escape from the ship. Due to the limited number of lifeboats (rafts), it is i...

AI Technical Summary

Problems solved by technology

[0003] Technical problem: In the event of a shipwreck, it takes a long time to organize personnel to take lifeboats (rafts), and they are easily affected by the vortex generated by the sinking ship and cannot escape. If those who escaped from the water are not good at swimming and cannot quickly move away from the sea area of ​​​​the sunken ship, they will also be involved in the vortex and die , while soaking in low-temperature water for a long time will lead to the death of the person who fell into the water
