Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle refueling, and relates to a vehicle-mounted unmanned aerial vehicle refueling system. Background Art

[0002] In order to adapt to different operational requirements and different terrain requirements, it is necessary to refuel the drone in a mobile and convenient manner. Existing mobile gas stations only have simple refueling and refueling functions. During the refueling, refueling and storage processes, there is a lack of oil purification. As a result, after long-term use, mobile gas stations will deposit impurities in the oil pipelines and oil storage tanks. These impurities will also flow with the oil, which will cause pipeline blockage in severe cases and reduce the quality of the drone oil.

[0003] Therefore, in view of the technical defect that the existing mobile gas stations lack oil purification during the refueling process, oil replenishment process and oil storage process, the utility model discloses a vehicle-mounted UAV refueling system. Utility Model Content

[0004] The utility model aims to provide a vehicle-mounted UAV refueling system, which can realize refueling of the UAV, self-circulation of oil, and refilling of the oil storage tank, and can purify the oil during the process of refueling, self-circulation, and refilling of the oil storage tank.

[0005] The utility model is realized by the following technical solutions:

[0006] A vehicle-mounted unmanned aerial vehicle refueling system comprises an oil storage tank, on which a refueling port, an oil return port and an oil drain port are provided, the refueling port is connected to a refueling gun via a refueling pipeline, and an oil return pipeline and an oil extraction pipeline are provided in parallel on one side of the refueling pipeline; electric valves are provided on the refueling pipeline, the oil return pipeline and the oil extraction pipeline, and an oil pump and a purifier are provided on the refueling pipeline; the inlet end of the oil return pipeline is provided between the purifier and the refueling gun, and the outlet end of the oil return pipeline is connected to the oil return port; the inlet end of the oil extraction pipeline is provided between the purifier and the refueling gun, and the outlet end of the oil extraction pipeline is provided between the refueling port and the oil pump.

[0007] When the drone is refueling, the electric valve on the refueling pipeline is opened, and the electric valves on the oil return pipeline and the oil extraction pipeline are closed. The oil inside the oil storage tank is transported to the refueling gun through the refueling pipeline by the oil pump. At the same time, the oil is filtered and purified by the purifier on the refueling pipeline, and the drone is refueled through the refueling gun.

[0008] When the oil is self-circulating, the electric valve on the oil return pipeline opens, and the electric valves on the refueling pipeline and the oil extraction pipeline close. At this time, the oil flows out from the oil outlet into the refueling pipeline under the action of the oil pump, passes through the purifier, and then flows back to the oil return port through the oil return pipeline, so that the purified oil returns to the oil storage tank, realizing the self-circulation purification of the oil.

[0009] When the oil needs to be added to the oil storage tank, the electric valves on the oil return pipeline and the oil extraction pipeline are opened, while the electric valve on the refueling pipeline is closed. At this time, under the suction of the oil pump, the external oil is reversely sucked into the oil extraction pipeline through the refueling gun. The sucked oil flows to the purifier through the outlet of the oil extraction pipeline for purification, and then is transported to the oil return pipeline, and then flows back to the oil storage tank through the oil return pipeline, so as to replenish the oil in the oil storage tank.

[0010] In order to better realize the utility model, further, a refueling reel is provided at the outlet end of the refueling pipeline, an oil pipe is wound around the refueling reel, and the outlet end of the refueling pipeline is connected to a refueling gun through the oil pipe.

[0011] In order to better implement the utility model, further, a pressure gauge is provided on the refueling pipeline between the purifier and the inlet end of the oil return pipeline.

[0012] In order to better realize the utility model, further, a regulating valve group is arranged between the inlet end of the refueling pipeline and the oil pump.

[0013] In order to better implement the present invention, further, the control valve group includes a stop valve and a pressure regulating valve connected in series.

[0014] In order to better implement the utility model, further, a first oil drain valve is arranged in parallel between the stop valve and the pressure regulating valve.

[0015] In order to better implement the utility model, further, a second oil drain valve is provided at the oil drain port.

[0016] In order to better realize the utility model, further, a carrying platform is provided at the bottom of the oil storage tank.

[0017] In order to better realize the utility model, further, a sealing cover is provided on the top of the oil storage tank, and an observation window is provided on the side wall of the oil storage tank.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] The utility model provides a refueling pipeline connected to the refueling port of the oil storage tank, and sequentially arranges an oil pump and a purifier on the refueling pipeline, so that the oil enters the purifier through the refueling pipeline for purification and then is transported to the drone through the refueling gun, thereby ensuring the purification of the oil during the refueling of the drone and the quality of the oil transported to the drone; at the same time, an oil return pipeline and an oil extraction pipeline are connected in parallel on one side of the refueling pipeline, and the self-circulation flow of the oil in the oil storage tank through the purifier is realized through the oil return pipeline, thereby purifying the stored oil in the oil storage tank, thereby avoiding the deposition of a large amount of impurities in the pipeline and the oil storage tank after the oil is stored for a long time; the external oil is sucked into the purifier through the oil extraction pipeline for purification, and then the oil is transported to the oil storage tank through the oil return pipeline, thereby purifying the oil in the oil storage tank during the oil replenishment process.

[0031] like Figure 2 As shown, the left and right ends of the bottom of the oil storage tank 1 are respectively provided with an oil drain port and a refueling port, and the top of the oil storage tank 1 is provided with an oil return port. The oil drain port is connected to an oil drain pipeline provided with a valve, and the oil stored in the oil storage tank 1 can be quickly drained through the oil drain pipeline. The refueling port is connected to the inlet end of the refueling pipeline 01, and the refueling pipeline 01 is sequentially connected in series with an oil pump 4, a valve, and a purifier 5. Under the power provided by the oil pump 4, the oil in the oil storage tank 1 flows to the refueling gun 2 after passing through the purifier 5, and the drone can be refueled through the refueling gun 2.

[0032] At the same time, a return oil pipeline 02 and an oil extraction pipeline 03 are arranged in parallel on one side of the refueling pipeline 01, and the inlet end of the return oil pipeline 02 and the inlet end of the oil extraction pipeline 03 are both arranged between the purifier 5 and the refueling gun 2, and an electric valve 3 is arranged between the inlet end of the return oil pipeline 02 and the inlet end of the oil extraction pipeline 03 on the refueling pipeline 01.

[0033] like Figure 2 As shown, when the UAV is refueled, the electric valve 3 on the refueling pipeline 01 is opened, while the electric valves 3 on the oil return pipeline 02 and the oil extraction pipeline 03 are closed. Under the power of the oil pump 4, the oil in the oil storage tank 1 is purified by the purifier 5 and then transported to the refueling gun 2. The UAV can be refueled through the refueling gun 2.
