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.

Anchoring device for adapting to tide level of wave energy power generation device, and operating method therefor

The present application relates to a method for selecting a wave height threshold, based on a target location, original wave height samples are acquired, and a wave height threshold interval are obtained; combined with wave height threshold and based on GPD and specified return period, a design wave height Hscorresponding to each threshold within the wave height threshold interval is calculated according to the sample wave height values which are greater that the threshold; a difference is calculated to obtain a stable threshold interval, and a threshold within the stable threshold interval is selected as a reasonable threshold for design wave height estimation. In this method, the stability of estimated values can be determined directly and objectively to realize wave height threshold selection.
