Description
Technical Field
The invention belongs to the technical field of water surface lifesaving, and particularly relates to an amphibious water surface lifesaving device based on box type wing pneumatic layout.
Background
The flood disaster is a natural disaster which frequently and seriously occurs at present, and the direct economic loss of the flood disaster accounts for about 60 percent of the total direct economic loss of various natural disasters. Flood disasters are characterized by high occurrence frequency, wide influence range and economic loss and weight.
However, although casualties and economic losses caused by flood often occur every year, safety rescue equipment for flood disasters is still relatively lacking. The existing rescue equipment mainly comprises: lifeboats, life rafts, hovercrafts, rubber boats, assault boats and the like, and most of the devices have the defects of large volume and weight, inconvenient storage and transportation, high difficulty in daily maintenance and the like. In addition, equipment driven by fuel oil power, such as lifeboats, submarines and the like, needs to take warming-up measures when being started in a low-temperature environment; the hovercraft has low dragging speed, so the number of the hovercraft reaching disaster areas in a short time is limited, and the use cost is high; the life raft, the rubber dinghy and the like have poor wind and wave resistance, are easily overturned under the influence of wind and waves, have insufficient power, and therefore have shorter rescue distance. Most importantly, the rescue equipment needs professional rescuers to risk driving to the trapped people and then rescue, and under the condition that water flow is very turbulent, the rescue action can be failed, and the safety of the rescuers can be damaged.
In recent years, a rescue method for throwing a life buoy by using an unmanned aerial vehicle is provided, and the problems are solved to a certain extent, but the method only simply uses the transportation function of the unmanned aerial vehicle and has poor throwing accuracy.
