Geological drilling anti-deviation device

The invention discloses a geological drilling anti-deviation device. The device comprises a drill pipe. The top end of the drill pipe is fixedly mounted with a motor. The top end of the drill pipe isfixedly provided with a fixed structure. The outer side of the bottom of the fixed structure is fixedly provided with a plurality of support legs. The bottom of the drill pipe is fixedly provided withan electrical box. The bottom end of the drill pipe is fixedly provided with a drill bit. By arranging the fixed structure, the diameter of the drill pipe can be adjusted arbitrarily, so that the drill pipe is fixed more firmly, the length of the arranged multiple support legs can be adjusted freely, the device adapts to fixing of uneven ground, an arranged infrared emitter is used for emitting infrared rays, a downstream path of the drill pipe is accurately measured, the arranged infrared sensor senses whether the downward path of the drill bit is consistent with the infrared rays, the pressure of the inner wall of t
