Beschreibung
Zusammenfassung:	The invention provides a blade locking device for a wind power draught fan set, which comprises a flange plate, a limiting disc and a locking mechanism, the locking mechanism comprises a friction disc, an annular base, an annular friction plate, an inner circle friction plate and a cone, the friction disc is arranged in the limiting disc, the annular base is positioned in a hub and forms a moving pair in the central axis direction of the flange plate, and the inner circle friction plate is arranged in the limiting disc. The annular friction plate is in friction contact with the bottom of the friction disc, and the friction face of the inner circle friction plate is in friction contact with the inner circle face of the friction disc. The annular base is pushed to move in the direction close to the limiting disc, so that the annular friction plate makes friction contact with the friction disc, the inner circle friction plate moves in the direction close to the inner circle face of the friction disc under the ac
