An inflatable water lifesaving device and lifesaving method

Abstract

The invention discloses an inflatable over-water lifesaving device and a lifesaving method. The lifesaving device comprises a floating body floating on the surface of water as well as an underwater propulsion mechanism, a laser radar and a controller which are arranged on the floating body; the propulsion mechanism is used for enabling the floating body to move; the laser radar is used for acquiring position information of to-be-saved person; the input end of the controller is connected with the laser radar; the output end of the controller is connected with the propulsion mechanism and a gasgenerator separately; and the controller drives the propulsion mechanism to operate and or triggers the gas generator to turn on according to the position information of the to-be-saved person. Through the inflatable over-water lifesaving device and the lifesaving method, which are provided by the invention, the condition that an unmanned boat cannot be close to man overboard under interference such as wave flow is responded, an inflatable over-water lifesaving device is controlled to arrive at the place near the to-be-saved person, and an airbag on the floating body is controlled to be expanded, so that the floating center of the floating body is changed and the man overboard who is in a coma or loses physical power can be salvaged automatically.

Description

technical field [0001] The invention relates to the technical field of water lifesaving equipment, in particular to an inflatable water lifesaving device and a lifesaving method. Background technique [0002] At present, the domestic and foreign rescue equipment and methods for the rescue of people who have fallen into the sea mainly adopt some more traditional rescue methods, such as launching cables, throwing life buoys, inflatable rubber rafts or helicopter rescue. But once the sea conditions are bad or the people who fall into the sea are injured or unconscious, the people who fall into the sea just cannot grasp or even approach the launched cables, thrown lifebuoys, and inflatable rubber rafts. If the weather conditions are relatively poor, the helicopters cannot approach. At this time, we can only rely on rescue personnel to carry out rescue, but the speed of rescue will slow down in this way, and the risk of death will increase by one point every time the time increas...

AI Technical Summary

Problems solved by technology

However, since the unmanned boat is an underactuated large inertia time-lag system, dynamic positioning cannot be achieved, and it is difficult to adjust to a suitable salvage position when the boat is close to the salvage target

In addition, it is also difficult to ensure that during the salvage process of the drowning personnel, the hull vibration will not increase due to the change of the center of gravity of the ship, which will cause secondary damage to the drowning personnel or even the entire ship capsizing.
