The invention provides an air inlet oil leakage prevention device of a piston engine oil tank of an unmanned aerial vehicle and the unmanned aerial vehicle. The air inlet oil leakage prevention device of the piston engine oil tank of the unmanned aerial vehicle comprises a mounting base, a fixing support, an air pipe and a balance weight part; the mounting base is provided with an assembling part used for being assembled with the unmanned aerial vehicle, the fixing support is rotatably mounted on the mounting base, the air pipe and the balance weight part are arranged on the fixing support, the air pipe is provided with a first port and a second port, and the second port is used for being communicated with an air inlet of an oil tank of the unmanned aerial vehicle. Compared with the prior art, according to the air inlet oil leakage prevention device of the unmanned aerial vehicle piston engine oil tank, when the oil tank inclines, the gravity action of the counter weight is utilized, the counter weight rotates to the lower position, and the first end opening of the air pipe rotates to the position higher than the counter weight; therefore, the first port of the air pipe can be kept higher than the air inlet of the oil tank, and the oil leakage prevention effect is achieved.

    本发明提供一种无人机活塞发动机油箱的进气口防漏油装置和无人机,无人机活塞发动机油箱的进气口防漏油装置,包括:安装座、固定支架、气管和配重件;所述安装座上设置有用于与无人机装配的装配部,所述固定支架可转动地安装在所述安装座上,所述气管和所述配重件设置在所述固定支架上,所述气管具有第一端口和第二端口,所述第二端口用于与无人机油箱的进气口连通。相对于现有技术,本发明的无人机活塞发动机油箱的进气口防漏油装置能够在油箱的倾斜的时候,利用配重物的重力作用,配重物向低处转动,而气管的第一端口则转动到相对配重物更高的位置,从而有利于保持气管的第一端口能够高于油箱的进气口,从而起到防漏油的作用。
