| description | The utility model discloses a safety protection device to be used for protecting a synchronous pitch converting device. The safety protection device comprises a first driving device and a clutch. When a pitch converting motor of the synchronous pitch converting device stops operating due to malfunction, the clutch separates the pitch converting motor and a pitch converting push rod of the synchronous pitch converting device, the first driving device is connected with the pitch converting push rod, the first driving device provides power for emergent feathering, safety of the pitch converting mechanism and a wind generating set can be guaranteed, safety protection when pitch converting driving loses efficacy is achieved, and operation of the first driving device is not blocked by the pitch converting motor and the pitch converting motor is not damaged due to the fact that the pitch converting motor and the variable-pitch push rod are separated. |
