An unmanned aerial vehicle and its working method

Abstract

The invention discloses an unmanned plane fueling vehicle and a working method thereof. The unmanned plane fueling vehicle comprises a vehicle body. An accessory bin, an operation bin and an oil tank assembly are arranged on a chassis of the vehicle body. A power assembly is arranged in the accessory bin. An oil circuit system, an electric system and a gas circuit system are arranged in the operation bin. The oil circuit system comprises three sets of fueling circuits and a main oil circuit. Each fueling circuit comprises a first manual ball valve connected with an oil tank. Each first manual ball valve is connected with a coarse filter. The coarse filter is connected with a first electromagnetic valve, a fifth electromagnetic valve and a ninth electromagnetic valve. According to the unmanned plane fueling vehicle and the working method thereof, functions and technologies are advanced, operation is easy, performance is reliable, a soft oil bag can be effectively protected in oil fueling and pumping processes, and the situations that the oil bag is damaged during fueling, or oil in the oil bag cannot be pumped completely during oil pumping, and consequently the service life of the oil bag is shortened are avoided. The unmanned plane fueling vehicle can also be applied to other fields that fuel is stored in soft oil bags and safety requirements are extremely high.

Description

technical field [0001] The invention relates to a UAV refueling vehicle, in particular to the field of refueling technology for UAVs using soft oil bags for fuel storage and high safety requirements, and is mainly used for refueling or extracting fuel for UAVs on site; The invention also relates to a working method of the drone refueling vehicle. Background technique [0002] In recent years, the drone industry at home and abroad has developed rapidly, but the current application level of drones in my country is only in its infancy, which also means that the domestic drone market has a huge room for future development. With the in-depth advancement of mechanization and information construction, the demand for domestic drones is growing rapidly, and the variety and quantity of drones will also increase. The application range of drones has involved many fields, but most drones are Facing the problem of low battery life, gasoline-powered drones will provide longer battery life...

AI Technical Summary

Problems solved by technology

With the in-depth advancement of mechanization and information construction, the demand for domestic drones is growing rapidly, and the variety and quantity of drones will also increase. The application range of drones has involved many fields, but most drones are Facing the problem of low battery life, gasoline-powered drones will provide longer battery life. In order to maximize the use of fuel load capacity and platform durability, the use of lightweight materials will undoubtedly increase the flight life of drones. At the same time, drones generally use soft fuel bladders

[0003] At present, in the field of UAVs, manual or electric fuel pumps are generally used to refuel UAVs. The above-mentioned refueling methods have the following problems: it is difficult to control the amount of fuel to be refilled and the refilling time is long. Note or electric fuel pump refilling is suitable for model aircraft and small UAVs, but not for medium or large UAVs, especially for UAVs with high safety requirements such as soft fuel bladders.
