Underground hole roadway transient electromagnetic probe capable of being self-adaptively centered

The utility model discloses an underground hole roadway transient electromagnetic probe capable of being self-adaptively centered, relates to the technical field of underground water body detection, and solves the problems that when the hole diameter of a drill hole is larger than the diameter of the probe, the probe cannot be centered in the hole, so that the detection accuracy of the probe is influenced, and the detection of a disaster-causing water body of a coal mine is not facilitated. According to the technical scheme, the device is characterized by comprising a detection rod, an EMC assembly is fixedly installed at the upper end of the detection rod, a protective cover is arranged outside the upper end of the detection rod in a sleeving mode, a tip cone head is fixedly installed at the end, away from the detection rod, of the protective cover, and installation grooves are formed in the outer ring face of the detection rod at intervals; positioning holes which are uniformly distributed are formed in the
