Mine vertical shaft system microwave power transmission device based on waveguide structure

The invention provides a microwave power transmission device of a mine vertical shaft system based on a waveguide structure. The microwave power transmission device comprises a receiving end and a transmitting end, the receiving end is mounted at the top of a cage and electrically connected with a power supply system in the cage, and the cage vertically runs along a coal mine vertical shaft; the transmitting end is installed at a vertical well mouth of a coal mine and electrically connected with a ground power supply system, and when a cage runs to the position of the well mouth, the receiving end is in butt joint with the transmitting end; the transmitting end comprises a signal source, an amplifier and a first waveguide; the receiving end comprises an anti-current connector, a second waveguide and a rectifying circuit; the first waveguide is matched with the second waveguide in shape; and the receiving end operates along with the to-be-charged device, and when the receiving end is in contact with the output
