Embodiment Construction

[0046] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0047] Such as Figures 1 to 18 As shown, the wind power generator includes a constant speed sample pinion shaft 1, a variable pitch drive shaft 2, a blade shaft gear 3, a fan blade main shaft 4, an anti-reverse gear 5, a main shaft housing support 6, a constant speed sample driver 8, blades 9 and a stroke switch 39 etc.

[0048] see in conjunction Figure 13 with 14 , the blade 9 includes a blade shaft, and the blade 9 rotates around the blade shaft to change the windward angle, that is, to change the pitch. The second end of the blade shaft is provided with the blade shaft gear 3 , and the stop plate 36 is provided on the blade shaft.

[0049] see in conjunction image 3 , the constant ...

Abstract

A wind power generator, comprising: an impeller unit comprising a blade main shaft (4) and a plurality of blades (9) provided thereon and driving the same to rotate; a constant speed template gear shaft (1) provided so as to be rotatable with respect to the blade main shaft (4); and a rotation speed difference acquisition unit comprising an input structure and an output structure, the input structure being connected between the constant speed template gear shaft (1) and the blade main shaft (4), and acquiring the rotation speed difference between the constant speed template gear shaft (1) and the blade main shaft (4), and the output structure being connected to the blades (9) and driving the same to rotate according to the rotation speed difference acquired by the input structure. The wind power generator can automatically change pitch.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a wind power generator. Background technique [0002] In today's energy shortage and environmental deterioration, wind energy, as a renewable clean energy, is increasingly valued and developed by countries all over the world. Due to the huge economic, social, environmental protection value and development prospect of wind energy development, wind power technology has made great progress in the past 20 years, and wind power development has the fastest growth rate among all kinds of energy development. At present, only the manufacturing technology of fixed-pitch wind turbines and the megawatt-level permanent magnet direct-drive synchronous generator technology that has just been put into use have not yet been improved in terms of large-scale wind turbines, variable pitch control, active stall control, variable speed and constant frequency and other advanced wind power...
