The present inventive concept relates to a lifesaving unit for rescuing water disaster victims, and more particularly, to a propulsion unit for a lifebuoy that can be stably propelled even if a buoyancy body provided to a water disaster victim is overturned.
In general, drowning accidents frequently occur in places with abundant water such as rivers, lakes, reservoirs, and the sea. These drowning accidents are caused by not responding promptly and appropriately to emergency situations such as inexperienced swimming, losing footing on a ship, and capsizing of a ship. Therefore, equipment capable of rescuing lives is installed in places where drowning accidents frequently occur, or lifeguards are present to prevent drowning accidents. These drowning accidents occur because such emergency situations occur unexpectedly and, in most cases, prompt rescue is not provided. In some unfortunate cases, ordinary people who have not received proper safety and rescue training directly participate in the rescue and instead drown together with a drowning person.
In addition, for a nearby drowning person, it is possible to rescue the drowning person from outside the water by throwing a life tube, rope, pole or the like at the drowning person. However, if the distance is far from a drowning person, even if a life-saving tube or rope is thrown at the drowning person, there is a high probability of failure because the life-saving tube or rope cannot reach the drowning person or does not reach a correct position. Even if it is successful, it takes a lot of time and the drowning person may lose consciousness or miss the rope or the like, making all rescue efforts futile.
Therefore, there is an urgent need for a lifesaving means capable of more safely and quickly delivering a lifesaving tube to a drowning person and guiding the drowning person to a safe place.
The present disclosure has been derived to solve the above problems and, more specifically, the present inventive concept has an object to provide a propulsion unit for a lifebuoy, which enables normal propulsion by changing the position of a propulsion part so that the propulsion part faces downward in the water, even if a lifesaving unit is overturned and landed on the water surface during lifesaving activities.
