Split blade hydraulic-magnetic transmission well hole cleaning tool

The invention relates to a split blade hydraulic-magnetic transmission well hole cleaning tool, which consists of a flow tube casing, a rotating magnetic core, an upper gauge protection body and a rotating blade, wherein the gauge protection body is arranged in a position, near the external screw thread part, of the outer wall of the flow tube casing, the outer wall of the flow tube casing is also provided with a position limiting ring, the upper gauge protection body is arranged at one side of the position limiting ring, the rotating magnetic core is integrally formed by a rotating tube and a rotating shaft, a transition connecting section of the rotating tube and the rotating shaft is provided with a drilling fluid hole, a hydraulic conversion device is fixedly arranged outside the rotating shaft, permanent magnets are uniformly distributed on the outer wall of the rotating tube, the two adjacent permanent magnets have the opposite magnetic pole directions, a rotating magnetic core is arranged in the flow tube casing, permanent magnets are uniformly distributed on the inner wall of the rotating blade tube body, and the two adjacent permanent magnets have the opposite magnetic pole directions; the hydraulic conversion device is a double-layer tubular body, and an axial pressure difference blade is arranged between the two layers of tubes; the rotating blade is split and dismountable. The split blade hydraulic-magnetic transmission well hole cleaning tool has the advantages that through the hydraulic-magnet coupling transmission, the limitation by the condition whether a drill rod rotates or not is avoided, the hydraulic-magnetic coupling transmission is realized under the condition of drilling fluid circulation, and the well hole cleaning efficiency is improved.
