ABSTRACT:
A floating overturn prevention device includes a flat-top base and a pillar coupled to a bottom surface of the flat-top base and extending therefrom. The flat-top base is a floating body for floating desired equipment on the water. The pillar further includes a weight member fixed on the bottom end of the pillar to maintain balance and keep the center of gravity of the floating overturn prevention device under the water. The floating overturn prevention device filter includes a balancing member coupled to the bottom end of the pillar. The balancing member includes a plurality of balancing plates vertical to the water level when the floating overturn prevention device balances on the water level. Therefore, the balancing plates can generate a reaction force to keep the floating overturn prevention device stable.
