Gravity-operated deep-sea anchoring device combining anchor with decelerating

An anchoring device having a decelerating wing, comprising:

• an anchoring base, being a floating body, and having a chamber formed therein, at least one groove formed in a bottom end thereof;
• at least one water diversion pipe installed at a side end of the anchoring base and communicating with the chamber, the at least one water diversion pipe having a switch valve;
• a support base disposed at a top end of the anchoring base;
• at least one main decelerating wing disposed upon the support base to cover the top end of the anchoring base, an outer edge of the at least one main decelerating wing tilting towards the anchoring base, a resistance space being defined between the at least one main decelerating wing, the support base, and the anchoring base;
• at least one secondary decelerating wing disposed on each side of the support base below the at least one main decelerating wing, an end of each secondary decelerating wing extending beyond a corresponding side end of the anchoring base;
• at least one anchor body pivotally coupled to the bottom end of the anchoring base within the at least one groove, and tilted relative to the bottom end;
• and
• at least one elastic spring having a first end disposed on a top wall of the at least one groove and a second end coupled to a top of a corresponding anchor body, each elastic spring being configured to elastically abut the corresponding anchor body, the corresponding anchor body thereby protruding from the groove.
