At present, for underground power transmission, only related research is carried out on a drill pipe or a drill string, the diameter of the drill pipe or the drill string is usually larger than 100mm, and power and signals can be transmitted simultaneously by adopting a wire butting method. No relevant research is seen on the design of power and signal transmission in the center rod of the core drill, the diameter of the center rod is usually below 35mm, and the center rod only performs axial drawing action unlike the drill rod or drill string which needs rotary drilling in operation, but the extremely small size limitation of the center rod causes that the power transmission is extremely difficult to perform in the center rod.
