The invention relates to the technical field of automatic equipment, in particular to a full-automatic cleaning device of an equal-diameter threaded wall deep pipe with an intelligent detector. The full-automatic cleaning device comprises a main frame and a rotating rack, wherein a bristle planting wall is arranged on an external wall of the rotating rack; brush bristles are arranged on the bristle planting wall; the main frame is provided with main support rods and auxiliary support rods; a connecting part is arranged at the end part of the outer end of each auxiliary support rod; the connecting parts are connected with wheel stands via pin shafts; a rotating wheel is arranged at each of the two ends of each wheel stand; and antiskid rubber tracks are arranged on the two rotating wheels in a surrounding manner. The full-automatic cleaning device of the equal-diameter threaded wall deep pipe with the intelligent detector can move freely on an internal wall of the deep pipe; the brush bristles can be used for cleaning in a moving or static process; and the full-automatic cleaning device solves the problem that the internal wall of the deep pipe cannot be cleaned.
