The utility model relates to a multidirectional adaptive suspended tidal current turbine, which comprises an upper balance wing, a lower balance wing, domes, turbine blades, electric generators, connecting fixing rods and anchor lashing rings; both the upper balance wing and the lower balance wing are installed above and below the domes respectively, the turbine blades are fixed on the outer side of a rotor of the electric generator respectively, the electric generators are fixed on the domes through the connecting fixing rods, and the anchor lashing rings are installed on the outer sides of the domes; and the domes have automatic suspension functions and also have good stability against overturning. After the multidirectional adaptive suspended tidal current turbine is installed, the suspension system can be adjusted with the stream in real time according to the changes in current direction, and the direction of incident flow is consistent with the axial lines of the domes, that is, the direction of incident flow is perpendicular to the rotating plane of the blades, so that the waterflow collection effect is remarkable, and the tidal current energy generation system has considerable generating efficiency at a lower flow velocity.
