The present invention includes high holding power anchor, hawse pipe, anchor mouth and anchor table. It adopts gravity sliding inward-inclined turning principle to implement said invention. By utilizing that the gravity of anchor is in the upper portion of its pin shaft, the pitch angle of the hawse pipe is designed into 35-50 deg., the inner mouth of anchor mouth is designed into that it has a flat-straight inner part, a linear contracted middle part and an expanded outer portion part, and its outer mouth has a smooth circular arc. The hawse pipe is welded on the ship body and upper deck in pitch angle of 45 deg., the lower end mouth of the hawse pipe is welded together with wide inner lower mouth of the anchor mouth, and the upper mouth of the curved plate of the side surface of the anchor table is welded with outer lower mouth of the hawse pipe. |
