The present invention provides an anchoring device with decelerating wing, balance mechanism and anti-collision gravity anchor base and impact pile body and anchor composite, comprising: gravity base, buoyancy unit, decelerating wing and impact pile body. Among them, a gravity base provides gravity to generate anchoring force with the weight and friction at the sea floor. The decelerating wing includes main decelerating wing and secondary decelerating wing, which lets water flow generate resistance when passing through the said decelerating wing and slow down the sinking speed of the gravity base to a safe region. Besides, buoyancy unit can absorb part of the impact energy when crashing the sea floor that results in deformation of the force to avoid being crashed by fast impacting on the sea floor. The impact pile body can be tube or solid column, which makes gravel, deposited soil on the sea floor or rock on the sea floor embedded by sinking speed and generates tremendous anchoring force. Thereby, the present invention provides excellent anchoring force by gravity with the weight and friction at the sea floor of gravity base and impact pile body that is compounded and shoveled into the sea floor. When doing deep-sea anchoring, it merely needs to move the area where is going to be anchored to make buoyancy unit inflow and lose buoyance and it can make gravity base slowly sink into sea floor by decelerating wings and maintaining balance of balanced anchor to finish anchoring work. It then has no construction costs on doing anchoring by manpower, which is applicable to all types of sea floor and is beneficial to laying offshore facilities and ocean current power generation equipment.
