An anchoring device for adapting to tide level for a wave energy power generation device comprises: a housing, wherein a central main shaft is provided at the center thereof, two ends of the central main shaft are respectively rigidly connected to a volute spring, and the interior of the housing is divided into several independent compartments, including a central compartment accommodating the central main shaft; a shaft lock and a central main gear capable of driving the central main shaft to rotate mounted on the central main shaft; and a plurality of hoisting wheel compartments arranged at equal intervals in a circumferential array around the central main shaft. A hoisting wheel is provided in each of the hoisting wheel compartments, and an anchor chain wound on the hoisting wheel protrudes out of the housing through an opening at the bottom of the hoisting wheel compartment.

A constant tension anchoring system mounted on a floating body in the ocean includes an anchor, an anchor chain, an anchor windlass, a towing cable, a load and a chain stopper. During the oscillatory motion of the waves, the constant tension anchoring system repeats the release and retraction so as to maintain a generally constant tension force and thereby ensure the safety of the anchoring system and the floating body.

An adaptor for an anchor including a first member configured for coupling a chain and a hollow second member for pivotally coupling an anchor. The second member defines a longitudinally extending blind slot on an inner surface and a longitudinally extending opening diametrically opposite the blind slot. The blind slot configured to restrict pivoting motion of the anchor within the second member and a swivel coupler for coupling the first member to the second member.

Method and apparatus for extending the operating depth of an existing shallow water anchoring system which includes a first cylindrical member having a plurality of fasteners thereon which slide over and attach to a distal end of the existing extendable anchoring pole and having a second cylindrical member with fasteners thereon which attach to a new extendable anchoring pole thereby forming a one-piece unit. The first cylindrical member can be slidably moved up and down the existing extendable anchoring pole so as to adjust the operating level of the new extendable anchoring pole so that the distal end of the new extendable anchoring pole can reach the bottom at a greater depth than the operating depth of the existing shallow water anchoring system. The new extendable anchoring pole is also slidable in the second cylindrical member for adjusting its operating depth.
