Well hole sand cleaning tool

The invention provides a borehole sand cleaning tool which comprises a center pipe, a first center flow channel and a second center flow channel which are not communicated in the axial direction are formed in the center pipe, a first through hole is formed in the side wall of the first center flow channel, and a second through hole is formed in the side wall of the second center flow channel; the sleeve is arranged on the central pipe in a sleeving mode, the two ends of the sleeve are rotationally connected with the outer wall face of the central pipe through rotating mechanisms correspondingly, and a rotational flow space is formed between the sleeve and the radial direction of the central pipe; therefore, the first center flow channel, the first through hole, the rotational flow space, the second through hole and the second center flow channel are sequentially communicated to form an overflowing channel. Wherein a plurality of wing ribs extending outwards in the radial direction are arranged on the outer wa
