The application discloses a double-
impeller wind power generator, and belongs to the technical field of
wind power generation. The double-
impeller wind power generator comprises a
tower, a pivot, two impellers, a transmission mechanism, a generator, a transmission mechanism, a
yaw mechanism and a
control system. The pivot is rotationally connected with the
tower through a bearing, and a
machine cabin is arranged at the top of the pivot. The two impellers are arranged at opposite ends of the
machine cabin respectively, the rotating direction of one
impeller is opposite to that of the other impeller, and the two impellers are transmissionally connected with the transmission mechanism. The input end of the generator is connected with the output end of the transmission mechanism. The
yaw mechanism is used for driving the pivot to rotate around the axial direction of the
tower, so as to change the orientation of the impellers. The
control system is electrically connected with the transmission mechanism, the impeller mechanism, the generator and the
yaw mechanism respectively, and is used for managing and monitoring the operation of the equipment. The application can reduce the
mechanical load of the
machine cabin, improve the wind energy capturing efficiency by optimizing the
stress distribution and enhancing the structural strength, and improve the power generation efficiency.
