The invention provides an impeller rotating device, an impeller assembling method and a wind power generator set. The wind power generator set comprises a generator and an impeller; the impeller rotating device comprises two or more pushing parts which are arranged on a rotor of the generator and are separated along the circumferential direction of the rotor at a preset angle; the impeller rotating device further comprises a pushing mechanism, and the pushing mechanism comprises a first linear driving unit and a second linear driving unit, wherein the first end part of the first linear drivingunit is hinged to a fixing structure of the wind power generator set, and a connecting part is separably connected with the pushing parts so as to push the rotor to rotate in a connected state; and the first end part of the second linear driving unit is hinged to the fixing structure, and the second end part of the second linear driving unit is hinged to the first linear driving unit so as to push the first linear driving unit to rotate around a hinged point between the first linear driving unit and the fixing structure. According to the impeller rotating device, the impeller assembling method and the wind power generator set, the problems that the impeller is difficult to assemble or even cannot be assembled due to limited assembling sites can be solved through a simple structure, meanwhile, the installation operation of blades can be simplified, and the installation cost of the blades can be reduced.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to an impeller rotating device, an impeller assembly method and a wind power generating set. Background technique [0002] A wind turbine is mainly composed of a tower, a nacelle, a generator and an impeller, and the impeller is a key factor in determining the power generation of a wind turbine. At present, the impeller is usually composed of a hub and three blades, and the generator is mainly composed of a rotor and a stator. Composition, wherein, the stator is connected with the base in the nacelle, and the rotor is connected with the impeller so as to be driven by the impeller to rotate relative to the stator along the axis of the rotor. In the actual installation process, the tower is usually hoisted on the foundation first, then the nacelle is hoisted to the tower, the generator is hoisted to the connecting flange of the nacelle again, and finally the impeller ass...
