Anchor system anchoring device and buoy

The utility model relates to an anchor system anchoring device and a buoy. The device comprises an anchorage and a hollowed-out ground gripping frame, the first side of the hollowed-out ground gripping frame is movably connected with the side face of the anchorage, and the hollowed-out ground gripping frame is provided with a hollowed-out part which is communicated from top to bottom. Compared with the prior art, the hollow ground gripping frame is arranged, and after the hollow ground gripping frame sinks into the seabed along with the anchorage, the hollow part can be filled with silt on the seabed, so that the hollow ground gripping frame sinks into the silt on the seabed; when the anchor is subjected to horizontal acting force, the horizontal acting force can be conducted to the hollowed-out ground gripping frame, the hollowed-out ground gripping frame sinks into seabed sludge, the sludge can prevent the hollowed-out ground gripping frame from moving in the horizontal direction, finally the anchor is prev
