Beschreibung
Zusammenfassung:	The invention discloses a noise reduction device for a wind turbine. The noise reduction device comprises a rotary noise reduction covering plate; the folding noise reduction covering plates are installed on the rotating noise reduction covering plate and located at the target position of the tower barrel, and the target position corresponds to the tail end position of the blade of the wind turbine when the blade moves to be parallel to the tower barrel; the rotating mechanism is used for driving the rotating noise reduction covering plate to rotate in the circumferential direction of the tower drum; the folding mechanism is used for folding or unfolding the folding noise reduction covering plate; and the control mechanism is used for driving the rotating mechanism and the folding mechanism to act, and the control mechanism is installed on the tower drum. According to the device provided by the invention, the whole set of device can be controlled by a yaw system to perform yaw wind alignment along with blades
