Description

Unmanned water drones for disasters The present invention relates to an unmanned water drone, and more specifically, to a disaster-use unmanned water drone capable of rapidly moving to rescue distressed persons in disaster situations such as water safety accidents. Small reservoirs and fishing grounds (hereinafter collectively referred to as "reservoirs") are among the places where water safety accidents frequently occur. Generally, since reservoirs are not equipped with separate rescue equipment for the event of a water safety accident, rescuers had to either enter the water themselves to rescue the victim or use a separate small boat. As such, in the past, when a water safety accident occurred, people had to rescue the distressed person directly, making a rapid response difficult. Consequently, delays in response time led to the loss of life during the golden hour for rescue, resulting in casualties. Furthermore, when a person used a boat for rescue, there was a risk of secondary safety accidents, such as the boat capsizing or running aground due to poor driving skills, and the rescue process interfered with other people performing other tasks. In response to these issues, unmanned water drones have recently been proposed. Patent Registration No. 10-2654024, "Water Rescue Drone," is equipped with a life tube connected to a winch; it allows for the rescue of a distressed person by lowering the life tube so they can grasp it, and then controlling the aircraft to move the person to a riverbank or coastline. However, since such water rescue drones must continue flying with the life tube suspended from the winch, they are unable to fly for extended periods; consequently, while they can be operated when a water safety accident is reported, they have the disadvantage of being difficult to operate on a regular basis. Patent Publication No. 10-2021-0083597, "Water Drone," comprises a video camera capable of surveying the surroundings, an infrared sensor capable of detecting a rescuer, a pollution measurement sensor capable of measuring water quality pollution, a speaker capable of transmitting voice to the rescuer, a lighting means capable of illuminating the rescuer, and a rescue rope mounted on the side for the rescuer to grasp, thereby enabling the search for and rescue of a drowning victim in the event of a drowning incident. Although the water drone is capable of rapidly deploying to rescue a drowning victim in the event of an incident, it has a problem in that it is difficult to operate continuously because it is shaped like a conventional boat, causing noise or waves during movement that interfere with the surroundings.
