Abstract

The invention relates to the technical field of wireless charging, and particularly discloses an inspection unmanned aerial vehicle wireless charging system, device and method based on high-voltage line energy taking. The system comprises a high-voltage electricity taking module, a wireless electric energy transmission module and an unmanned aerial vehicle charging module which are connected in sequence. The wireless power transmission module comprises a primary side voltage adjusting unit, a coupling unit and a secondary side voltage adjusting unit which are connected in sequence. The primaryside voltage adjusting unit is connected with the high-voltage electricity taking module, and the secondary side voltage adjusting unit is connected with the unmanned aerial vehicle charging module.The coupling unit comprises a transmitting coil connected with the primary side voltage adjusting unit, a receiving coil connected with the unmanned aerial vehicle charging module, and a multi-stage relay coil arranged between the transmitting coil and the receiving coil. The plurality of relay coils can effectively improve the transmission distance, and in combination with the insulator structure, not only can the requirement for the insulation distance between the high-voltage side and the low-voltage side be ensured, but also the size and the weight of the wireless power transmission moduleare reduced.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging system, device and method for a patrol drone based on high-voltage line energy harvesting. Background technique [0002] In recent years, with the rapid construction of my country's power grid and the rapid development of transmission lines of various voltage levels, in order to ensure the safe operation of the power grid, power inspection is an indispensable task. Compared with the traditional manual inspection, UAV inspection saves a series of high-level complex actions such as manual climbing, and the observation of special phenomena on high-voltage towers and power lines can be done through the PTZ camera on the UAV. Therefore, it has the advantages of safety, high efficiency and precision; secondly, the UAV can fly along the power line at high altitude, and the complex ground environment has no influence on the inspection process of the UAV, whi...
