Disclosed is a control mechanism for a waterwheel device, wherein the waterwheel device comprises a waterwheel shaft (10), a plurality of blade carriers (12) radially distributed on the waterwheel shaft (10), a plurality of blades (2) which are respectively installed on the plurality of blade carriers (12), and pivot shafts (20) which are installed in the corresponding blade carrier (12), allowing one of the plurality of blades (2) to be pivoted relative to the corresponding blade carrier (12). The control mechanism comprises: stopper portions (22), provided on the blade (2) which is pivoted relative to the pivot shaft (20); and a control element (3), which in a first situation, abuts against the stopper portion (22) and limits the pivoting of the blade (2), which while in a second situation, is disabled to abut against the stopper portion (22), so that the blade (2) is pivoted relative to the corresponding blade carrier (12). |
