Abstract:
1. A wind power generating device, comprising: a tower column; a first wind generating set installed at a position on the tower column within a predetermined distance from a top, of the tower column, the first wind generating set that generates a first torque on the tower column during rotation for power generating; and at least one second wind generating set installed at a position on the tower column below the first wind generating set, wherein the at least one second wind generating set generates a second torque on the tower column during rotation for power generating, and the second torque at least partially counteracts with the first torque; a bearing causing a mechanical connection between the at least one second wind generating set and the tower column; an electrical brush causing an electrical connection between the at least one second wind generating set and a cable inside the tower column; and a yawning system causing the at least one second wind generating set to rotate around the tower column toward any direction.
