The invention discloses a wind-induced vibration turbulent flow device for a flexible tower of a shrinkage-type wind generating set, and aims at solving the technical problems in the prior art that when the wind generating set is in a halted state, a flexible tower structure is easily damaged by vortex-induced vibration, and an existing turbulent flow device for inhibiting vortex-induced vibrationis subjected to wind-load fatigue damage for a long time when the wind generating set works normally. The wind-induced vibration turbulent flow device for the flexible tower comprises a foundation fixedly connected with the ground, a tower is installed on the foundation, a cabin is installed at the end, away from the ground, of the tower, a hub used for installing blades is installed on the cabin, the outer surface of the tower is provided with turbulent flow device bodies which are spirally distributed, and the included angle between turbulent flow plates of the turbulent flow device bodiesand the outer surface of the tower can be adjusted through a driving member. The flexible tower wind-induced vibration turbulent flow device has the following advantages that the turbulent flow devicebodies effectively inhibit vortex-induced vibration, the turbulent flow device bodies in the closed state cannot influence operation and power generation of the unit, and the problems of external loads and noise on the tower are solved while the wind-load fatigue damage to the turbulent flow device bodies is lowered.
