Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the unmanned aerial vehicle oil supply system includes an engine 20, a main oil tank 10, a secondary oil tank 30 located on the same horizontal plane as the engine 20, and an oil pump 40 connected between the main oil tank 10 and the secondary oil tank 30 and used for pumping fuel oil from the main oil tank 10 into the secondary oil tank 30, wherein an oil supply pipe 50 is connected between the secondary oil tank 30 and an oil inlet of the engine 20, and an overflow pipe 60 is connected between the secondary oil tank 30 and the main oil tank 10.
When the unmanned aerial vehicle works, fuel in the main fuel tank 10 is pumped into the auxiliary fuel tank 30 by the oil pump 40, the overflow pipe 60 is connected between the auxiliary fuel tank 30 and the main fuel tank 10, the auxiliary fuel tank 30 can be in a full-oil state and the oil level can be kept stable as the oil pump 40 continuously pumps the fuel into the auxiliary fuel tank 30, the capacity of the auxiliary fuel tank 30 is smaller than that of the main fuel tank 10, the problem that the oil level of the auxiliary fuel tank 30 is too low can be avoided, and when the pitch angle or the roll angle of the unmanned aerial vehicle is greatly changed, the problem that the fuel cannot be contacted with the oil at the oil outlet of the auxiliary fuel tank 30 and air is; because the auxiliary fuel tank 30 and the engine 20 are positioned on the same horizontal plane, fuel in the auxiliary fuel tank 30 only enters the engine 20 under the suction force of the engine 20, the phenomenon that fuel is insufficiently combusted and discharged due to excessive fuel supply can be prevented, and the waste of fuel and the flameout of the engine due to excessive fuel can be avoided; the utility model discloses an unmanned aerial vehicle oil feeding system has solved current unmanned aerial vehicle and has caused the flame-out problem of engine because of the fuel feeding is too much or not enough, has not only reduced the fuel consumption, can improve the time of endurance moreover.
