Magnetic coupling charging device

A magnetic coupling charging device belongs to the technical field of coal mine underground inspection robot charging devices and comprises a charging assembly and a receiving assembly. And the charging assembly is connected with the receiving assembly, so that the receiving assembly completes charging under magnetic coupling connection. The magnet coupling charging device is installed at a track of the underground coal mine track robot, power is obtained through interaction of a receiving end coupling magnet and a charging end coupling magnet of a robot end, electricity is generated through rotation of an electromagnet, and the electricity is stored in a storage battery of the robot end. According to the underground inspection robot charging device, automatic charging of the underground inspection robot is achieved, stable endurance support is provided for work of the underground inspection robot, all electric components are subjected to explosion-proof isolation, the safety performance of the charging devic
