Problems solved by technology
[0003] The soft fuel bag is made of non-metallic materials, and its working pressure is generally 3-5kPa. If multiple pressure control and protection methods are not used for closed refueling, it will cause damage to the fuel bag; at the same time, it will not cause quantitatively added fuel when the refueling is stopped. Loss due to siphon; In addition, when the oil needs to be pumped back after the soft oil bag works, the oil suction resistance is large due to the small oil suction caliber, and the suitable vacuum degree cannot be guaranteed, which will cause the fuel in the oil bag to be sucked dirty, which will affect the life of the oil bag. great influence

The invention relates to a closed oil filling / pumping adaptor. The closed oil filling / pumping adaptor comprises an oil receiving adaptor mounted in an oil port of a soft oil bag of an unmanned aerial vehicle launching box, and an oil filling adaptor mounted at a power oil outlet end of an oil filling vehicle, wherein the oil receiving adaptor comprises a shell having an oil receiving cavity; an oil receiving inlet and an oil receiving outlet externally connected with the oil bag are respectively formed in the two ends of the oil receiving cavity; the oil filling adaptor comprises an oil inlet and an oil outlet; the oil outlet is connected with the oil receiving inlet of the oil receiving adaptor; a stabilizing valve is arranged in the oil filling adaptor; and one end of the stabilizing valve is connected with the oil inlet, and the other end is communicated with the oil receiving adaptor through a first quick joint. The closed oil filling / pumping adaptor is high in integration degree, compact in structure and simple in operation, can effectively protect the safety of the soft oil bag in the oil filling / pumping process, prevents the damage of the oil bag in the oil filling or the shortening of service life of the oil bag caused by insufficient pumping of oil in the oil bag in the oil pumping, has the key effect on the realization of oil filling / pumping of the soft oil bag with high pressure control requirement, and can realize sufficient pumping of the oil bag.
Description
technical field [0001] The invention relates to a closed adapter for refueling and pumping, which is used in the field of unmanned aerial vehicle power technology where fuel is stored in soft oil bags and has high safety requirements. Background technique [0002] With the strengthening of the construction of domestic drones, the application scope of drones has involved land and resources investigation, environmental monitoring, water monitoring, disaster relief and other fields, and it is playing an increasingly important role at the moment. An area of focus that is being vigorously developed. 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 UAVs. UAVs generally use soft fuel bladders. [0003] The soft fuel bag is made of non-metallic materials, and its working pressure is generally 3-5kPa. If multiple pressure control and protection methods are not used for closed r...
