Abstract

The invention provides a flexible oil taking device and an unmanned aerial vehicle with the same. The flexible oil taking device comprises a heavy hammer, a flexible oil taking pipe, a sealing ring and an oil conveying opening cover. The heavy hammer is of a hollow structure, a through groove is formed in the oil taking face of the heavy hammer, and the flexible oil taking pipe is connected between the heavy hammer and the oil conveying port cover. The oil conveying port cover is of a hollow structure, a first connecting part and a second connecting part are arranged on the oil transportation port cover, the oil transportation port cover is fixedly connected with an aircraft through the first connecting part, and the oil transportation port cover is fixedly connected with an oil transportation pipeline on the aircraft through the second connecting part; and the sealing ring is arranged between the first connecting part and the aircraft. The flexible oil extractor has the advantages of being good in oil supply effect, simple in structure, modular in design, convenient to use and low in cost, and can be used for the unmanned aerial vehicle using liquid fuel so as to meet the oil supply requirement when negative overload occurs under the maneuvering flight condition of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of aircraft fuel supply, in particular to a flexible oil picker and an unmanned aerial vehicle equipped with it. Background technique [0002] A certain type of UAV uses liquid fuel as a power source. When the UAV conducts maneuvering flight and generates negative overload, it needs continuous and uninterrupted supply of fuel. In order to prevent fuel supply from being interrupted and endangering flight safety, various types of fuel supply devices under negative overload conditions are commonly used in the fuel system. [0003] At present, the commonly used anti-load overload devices mainly include overload box plus ejector pump, inverted oil tank, movable piston and soft oil tank, etc. An ejector device is required for the overload tank and ejector pump; the structure of the inverted oil pool is complex; the movable piston and the soft oil tank physically isolate the air from the fuel, and have a strong an...
