The wind driven generator mainly comprises an impeller, a cabin, a tower, a control system, a yaw system, a hydraulic system, wind condition acquisition equipment and a power supply device, wherein a coupler is designed between a high-speed end of a speed-increasing gear box and a generator of the existing wind driven generator set, the coupler can rotate at different speeds under normal operation and maintenance working conditions, and a protective cover device is usually installed on the outer side of the coupler in order to ensure the safety of operators of the wind driven generator set and equipment in the cabin. In order to meet the on-site hoisting requirement, a part of large wind turbines can be also provided with a barring gear, so that a gear ring is arranged on the outer ring of a coupler brake disc to cooperate with the barring of the wind turbines. In addition, the temperature inside the cabin of the wind turbine generator is higher under the generating working condition of the wind turbine generator, and a set of axial flow fan needs to be separately configured for ventilation.
An existing coupler shield adopts a shield body structure with supporting legs, corresponding supporting structures are required to be arranged on the shield body structure to support the shield body, the supporting legs of the shield body structure are usually in a long strip shape, and stability of the whole supporting structure is reduced.
