Abstract
An impeller locking device for a wind generator is provided. The impeller locking device includes a locking hole formed on an impeller connecting disc, and a locking pin configured to fit into the locking hole. The locking pin is connected with a base of the wind generator; and when the locking pin is locked in the locking hole, a radial clearance is provided between the locking pin and the locking hole. When the axes of the locking pins and the locking holes are deviated radially, the locking pins can also be inserted into the locking holes, so that radial constraints of the locking pins and the locking holes are eliminated. A wind generator adopting the impeller locking device is further provided.
