Claim 7:
8. An operating method of the anchoring device of claim 1, comprising:
after fixing the free ends of multiple anchor chains on the seabed, scaling up or scaling down the anchor chain to make the anchoring device float on the sea surface; and
locking the shaft lock for a period of time, and then releasing the shaft lock for a period of time, wherein
when the shaft lock is locked, the central main shaft cannot rotate, and when the shaft lock is released, the central main shaft can rotate,
when the tide level rises:
while the shaft lock is in a locked state, the anchor chain is prevented from protruding and gradually tightens, the drainage volume of the anchoring device for adapting to tide level increases, and the water level line rises, and
while the shaft lock is in a released state, the anchor chain protrudes to drive the hoisting wheel where the anchor chain is located to rotate, the hoisting wheel rotates to drive the corresponding horizontal axis to rotate via a chain, then drives the corresponding vertical shaft to rotate by the transmission between the vertical bevel gear and the transverse bevel gear, and finally drives the central main shaft to rotate via the gears on the vertical shafts that mesh with the central main gear at the same time, so that the volute springs on both ends of the central main shaft shrink and store energy, and

when the tide level drops:
while the shaft lock is in the locked state, the anchor chains are prevented from retracting and gradually slacken, and
while the shaft lock is in the released state, the volute spring releases elastic potential energy and drives the central main gear to rotate in a direction opposite to a direction of rotation when the tide level rises, so as to drive the hoisting wheel of at least some of the plurality of hoisting wheel compartments to rotate via corresponding vertical and horizontal axes respectively, so that automatic retraction of the anchor chains is achieved.
