ANCHOR Russian patent published in 1997 - IPC

FIELD: shipbuilding. SUBSTANCE: anchor comprises shank 1 and suction part provided with recess on side of its base and made in the form of truncated cone 7 with bead 8 and flat longitudinal spokes 6 resting against spherical support 4 engageable with shank 1; when anchor is embedded in soil, upper portion of bead 8 rests against shank 1 and upper portion becomes perpendicular to direction of application of load. Soil is free to pass through spaces between spokes 6, thus providing for deep embedding. In case anchor comes to absolute obstacle in form of cable or rope, vector of buoyant force is directed upward and anchor is forced out to surface of soil. EFFECT: increased holding power of anchor. 2 dwg
