Portable drowning lifesaving device

Abstract

The invention discloses a portable drowning lifesaving device which comprises a bottom reaction unit, a shell, an air bag and a top knob switch unit. The folded air bag is placed in a right side of the shell, and several binding belts are arranged at one end of the shell. When the whole device is in water, the top knob switch unit is turned on so that the air bag is unbound; a first spring pushesthe air bag out from the inside; meanwhile, external water is sucked into a mounting groove through the through holes in the mounting groove; after the first spring extends to a certain extent, pressure on a second spring is weakened; the second spring starts to extend to push a gasket; a supporting insertion plate is pushed by the first spring to be tightly pressed at a through hole bulge of themounting groove; and after the whole locking block is pushed away by the gasket, chemical substances in the mounting groove make contact with water entering the mounting groove previously to generatea large amount of gas, the air bag is in a sealed state, the large amount of gas is generated in the air bag to enable the air bag to be inflated rapidly, and buoyancy is provided for a user to achieve a self-rescue function.

Description

technical field [0001] The invention relates to the field of drowning lifesaving, in particular to a portable drowning lifesaving device. Background technique [0002] There are many drowning accidents in the world every year. Some people drown in the water because they are not used to water or because of cramps, but there are also many people who drown because they entered the water to save people. When someone is drowning, it is difficult for the nearby people to find suitable floats for the drowning person in time. The inflatable swimming ring is too light and cannot be thrown far away, and the wood is too heavy. Professional lifebuoys are not always available, and more often it is the people on the shore. Go directly into the water to save people, and the drowning person directly entangles the rescuer due to panic, causing the two to sink together, which is very dangerous.

Problems solved by technology

The water-soluble thread wraps the inner structure of the airbag outside the airbag and then unlocks it, and it will not rotate because it is bound by the water-soluble thread. At this time, throw the life-saving bracelet to the drowning person in need, and the water-soluble thread will dissolve in water and Removing the restraints allows the life-saving bracelet to complete the inflation process and provide additional buoyancy for the drowning person. However, the airbag is exposed to the outside and is easy to wear and leak air. The water-soluble thread needs to be temporarily wound to delay the rescue. The user does not take it with him and thus delays the rescue. For this reason, we propose a portable drowning life-saving device to solve the above problems
