Multifunctional marine lifesaving device

Abstract

The invention discloses a multifunctional marine lifesaving device which comprises an inflation air bag for serving as a temporary shelter place, a wind power generation system, a wave power generation system, a positioning and navigation system, a solar cell panel and electric heating pipes. The inflation air bag is of a double-layer structure, and a switch valve, a manhole and a breather valve are respectively arranged on the inflation air bag. The wind power generation system is arranged outside the inflation air bag. The positioning and navigation system is arranged at the top of the inflation air bag. The solar cell panel is arranged outside the inflation air bag. The electric heating pipes are arranged in an inflation air bag interlayer. The multifunctional marine lifesaving device is simple in structure and convenient to operate, can rapidly provide a warm and food-supplying safe place where fresh air can be provided, positioning can be performed and the danger can be avoided for persons in distress after marine perils occurs, the time for waiting for rescue is prolonged, and the survival rate of the persons in distress is improved.

Description

technical field [0001] The invention belongs to the field of sea rescue, and in particular relates to a multifunctional sea lifesaving device. Background technique [0002] According to statistics, as many as 100,000 people die every year due to shipwrecks all over the world. Maritime dangers are characterized by suddenness, great harm, and difficulty in rescue. The main reasons for the death of people in distress at sea are as follows. ① After falling into the water, the water temperature is low, resulting in death. The temperature of the human body is generally not lower than 35 degrees Celsius, while the temperature of seawater is generally lower than 20 degrees Celsius. In winter and at night, the temperature of seawater can be as low as below 10 degrees Celsius. The survival time of people in 0-4 ℃ ice water generally does not exceed 30 minutes. In the Titanic incident, thousands of people fell into the sea water, and most of them were frozen to death within ten minut...

AI Technical Summary

Problems solved by technology

① After falling into the water, the water temperature is low, resulting in death

③Death due to lack of water and nutritional supplements

Once a marine accident occurs, the scope of rescue is often very large, and it is difficult to find the victim at the first time. Therefore, it is difficult to survive for more than 3 days without supply personnel.

[0003] The existing marine lifesaving devices mainly include life buoys, life jackets, life rafts, etc. Although they can help people in distress not to sink into the water in a short period of time, they cannot solve the key problems that lead to death, such as low temperature, choking water, and lack of nutritional supplements.
