1. An anchoring device for adapting to tide level for a wave energy power generation device, comprising:
a housing with a central main shaft provided at a center thereof, wherein
two ends of the central main shaft are respectively rigidly connected to a volute spring,
a shaft lock and a central main gear capable of driving the central main shaft to rotate are mounted on the central main shaft,
an interior of the housing is divided into a plurality of independent compartments, including a central compartment accommodating the central main shaft, and a plurality of hoisting wheel compartments are 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, an anchor chain wound on the hoisting wheel protrudes out of the housing through an opening at a bottom of the hoisting wheel compartment, each side of the hoisting wheel is provided with an extension shaft, and a first chain wheel is installed on the part of the extension shaft that passes through the hoisting wheel compartment,
a plurality of horizontal shafts respectively corresponding to the hoisting wheel compartments and vertical shafts respectively corresponding to the horizontal shafts are arranged in the central compartment, and a vertical bevel gear is fixedly installed on each horizontal shaft, and
a transverse bevel gear meshing with the vertical bevel gear and a gear meshing with the central main gear are installed on each vertical shaft, a second chain wheel capable of driving the horizontal shaft to rotate is installed on a part where both ends of each horizontal shaft pass through the central compartment, and the first chain wheel and the second chain wheel are connected by a chain drive.
