Technical field

The utility model relates to the technical field of emergency rescue, specifically an amphibious lifesaving stretcher and a control module.

Background technique

As my country's development of waters or sea areas increases, the frequency of people's maritime activities has gradually increased, resulting in frequent drowning accidents. The existing methods of placing lifebuoys are all manual, which is difficult to accurately throw. Moreover, many areas on the water that need rescue are inaccessible and cannot be rescued in a timely manner. The cost of using helicopters for rescue is high and the maneuverability is poor. With the development of science and technology, drones have begun to be used in various industries due to their advantages of low cost, fast flight speed and short preparation time. In view of the need for rapid response in water rescue, drones with fast response and strong maneuverability have been widely used in water rescue. Using a drone to carry a lifebuoy is a common method, but because this method requires taking the lifebuoy and the drone out of the storage location in advance, and then carrying out the operation after simple debugging, the preparation time is relatively long. There are errors and there is no guarantee that a person who falls into the water will get it. Patent No. 201921252749. Slow, not suitable when the sea conditions are bad or the distance is too far;

Our company has proposed a flying lifebuoy, and its patent number is CN213921429U; it solves the above technical problems well, opens up a new idea for water rescue, and has broad application prospects; in some rescue processes, active rescue is required , if the person to be rescued is weak, children or women cannot swim to the shore (safe area) by themselves after using the lifebuoy; therefore, it is necessary to consider actively pulling the person to be rescued to the shore (safe area). In addition, when multiple people need rescue , the current rescue equipment cannot provide good rescue; for this reason, our company carried out further development and design during the production and research and development process, and proposed an amphibious rescue stretcher and control module.
