The utility model provides a removal ballast leveling control device of floating fan can restrain the slope and motion response of floating fan. Including portable ballast, smooth movable rail way, limit bearing and leveling control server etc.. Portable ballast has power, brake and locking system, can slide on the track by the receive real -time signal, and braking and lock are died. Smooth movable rail says according to floating wind turbine foundation's overall arrangement and usable space settings to lay the ballast and remove required slide rail, hinge, lead screw etc. Orbital tip sets uplimit bearing, prevents ballast roll -off track to place the auxiliary assembly of ballast power. Real -time initiative control command according to the velocity magnitude and the direction monitoring data of wind, wave, stream, is sent to removing ballast to the mountable of leveling control server in the deck or a fan tower section of thick bamboo on basis.
