The invention relates to a charging platform of an unmanned aerial vehicle for high-voltage transmission line inspection. The charging platform comprises a current mutual inductance mechanism, a rectification and voltage stabilization module and a charging platform; the current mutual inductance mechanism is used for obtaining electric energy from a high-voltage transmission line; the output end of the current mutual inductance mechanism is connected with the input end of the rectification and voltage stabilization module, the output end of the rectification and voltage stabilization module isconnected with the input end of the charging platform, a plurality of magnetic attraction charging devices and a plurality of infrared transmitters are installed on the top surface of the charging platform, magnetic metal contacts and receivers are correspondingly installed on the multi-rotor unmanned aerial vehicle, and a fixing mechanism is mounted on the bottom surface of the charging platform. According to the invention, stable charging of the unmanned aerial vehicle on the charging platform can be ensured without additionally installing a mechanical fixing device, and the device can automatically charge the multi-rotor unmanned aerial vehicle for high-voltage power transmission line inspection as long as stable current always flows through the power transmission line body.

Description

technical field [0001] The invention belongs to the field of multi-rotor unmanned aerial vehicles, and relates to a charging device for multi-rotor unmanned aerial vehicles, in particular to a charging platform for unmanned aerial vehicles for inspection of high-voltage transmission lines. Background technique [0002] In recent years, with the expansion of the grid scale and the large increase in the amount of high-voltage transmission line equipment, the traditional manual inspection method is inefficient and cannot meet the requirements of existing line operation and maintenance. Instead, UAV, as an emerging technology, has been widely used in the inspection of high-voltage transmission lines. It has the advantages of high inspection efficiency, high inspection accuracy, no terrain restrictions, and low economic cost. However, in the process of using it for line inspection operations, due to the long flight distance, the initial power of the battery when the UAV takes off...

AI Technical Summary

Problems solved by technology

Indoor charging is the traditional manual charging method, which requires drone operators to charge the spare battery of the drone indoors in advance, and manually replace it after arriving at the job site

Outdoor charging is mostly an integrated UAV machine nest installed on the top of a high-voltage transmission tower, with a complex mechanical structure inside, low system reliability, difficult maintenance, and high cost

At the same time, this technology also faces the difficulty of transmitting electric energy from high potential (transmission line body) to ground potential (high voltage transmission tower)
