Small rescue unmanned aerial vehicle

Abstract

The invention relates to a small rescue unmanned aerial vehicle which is used in cooperation with a rescue helicopter or a ship. The small rescue unmanned aerial vehicle comprises an unmanned aerial vehicle body, an inflation device, a life buoy, a life buoy storage device and a bobbin, wherein the life buoy storage device is an annular container with a storage groove at the bottom; the inflationdevice is provided with an inflation needle; the inflation needle is arranged at the top of the inner side of the life buoy storage device; the life buoy is arranged in the storage groove in a foldingmode; the life buoy comprises a life buoy body and an air nozzle, and the inflation needle is inserted into the air nozzle; the bobbin can be rotationally and horizontally fixed on the inner ring ofthe life buoy storage device; and a traction rope is arranged on the bobbin, and one end of the traction rope is tied on the life buoy. According to the small rescue unmanned aerial vehicle, the smallor micro unmanned aerial vehicle with low price serves as a carrier, the search and rescue cost is greatly reduced, the search and rescue visual field is wide, the searching range is large, and the mode is superior to a search and rescue mode of throwing or casting a large number of life-saving equipment in a certain area; the search and rescue personnel do not need to go deep and rescue, and thesafety of the search and rescue personnel is improved.

Description

technical field [0001] The invention belongs to the field of water rescue, and in particular relates to a small rescue drone. Background technique [0002] When in distress or trapped at sea, lakes, reservoirs, rivers and flood disasters, it is necessary to search and rescue missing or trapped persons. Search and rescue equipment includes assault boats, helicopters, search and rescue boats, rope throwers, life buoys, life jackets, etc. , and the use of flying equipment for high-altitude search and rescue is undoubtedly a more efficient search and rescue method. For example, using helicopters to directly search and rescue rescue targets is a very direct and fast method, but helicopters are expensive and consume a lot of energy, which will greatly increase search and rescue costs. , and a small number of helicopters are difficult to complete a large number of search and rescue work, the helicopter from the response to reach the search and rescue area, and then to carry out the...

[0002] When in distress or trapped at sea, lakes, reservoirs, rivers and flood disasters, it is necessary to search and rescue missing or trapped persons. Search and rescue equipment includes assault boats, helicopters, search and rescue boats, rope throwers, life buoys, life jackets, etc. , and the use of flying equipment for high-altitude search and rescue is undoubtedly a more efficient search and rescue method. For example, using helicopters to directly search and rescue rescue targets is a very direct and fast method, but helicopters are expensive and consume a lot of energy, which will greatly increase search and rescue costs. , and a small number of helicopters are difficult to complete a large number of search and rescue tasks. The process of helicopters responding to the search and rescue area and then to the implementation of search and rescue also takes a certain amount of time, which may lead to missing valuable search and rescue time and reduce the possibility of rescue targets surviving

[0003] With the popularization and continuous development of UAVs, the use of UAVs to search for rescue targets and release life-saving equipment is being used more and more; and the use of UAVs to directly rescue rescue targets requires UAVs to provide sufficient The lifting force or pulling force of the general micro-UAV or small UAV cannot be realized at all, and it needs to pay a high cost to equip a large UAV

[0004] When people move in water, there is a lot of resistance, and they are often faced with unfavorable situations such as waves, wind, and currents. Micro or small UAVs do not have enough power to drag people in the water to move to the target area, even if they use a certain pulling force (such as with Larger UAVs with a lift force of more than 20kg) for direct rescue, and drag the resc
