Abstract

The present invention relates to a kind of blade screw-free fixing device for wind power generator.Including blade-flange, fan blade, blade-flange is fixed on generator shaft by the nut that front end is arranged, blade-flange is provided with draw-in groove and the draw-in groove with fan blade root matches, and fan blade rear end arranges fan blade pressing plate and fixes fan blade, is provided with the flange fixing fan blade pressing plate of only circle after fan blade pressing plate.The present invention directly coordinates fixing connection by arranging draw-in groove on blade-flange with the draw-in groove of fan blade root, and utilize fan blade pressing plate and flange only circle to be fixed, instead of the structure being in the past screwed fan blade, make the fixing more firm of fan blade, also simplify the structure of wind-driven generator, easy for installation.

Description

A kind of blade screw-free fixing device for wind power generator
Technical field
The present invention relates to the vane fixer of a kind of wind-driven generator, particularly relate to a kind of blade screw-free fixing device for wind power generator.
Background technology
The fan blade of wind-driven generator is generally screwed on blade-flange, this kind of structure is in running, owing to the rotating speed of its fan blade can increase along with the increase of wind speed, when wind speed is too high, may result in the loosened screw of fixing fan blade, make fan blade fracture of root.Appearance in order to avoid this type of situation, it is necessary to make the fixing more firm of fan blade.
Summary of the invention
The present invention is to solve problem above provide a kind of be connected firmly, the blade screw-free fixing device for wind power generator of simple in construction.
The technical scheme is that and include blade-flange, fan blade, blade-flange is fixed on generator shaft by the nut that front end is arranged, blade-flange is provided with draw-in groove and the draw-in groove with fan blade root matches, fan blade rear end arranges fan blade pressing plate and fixes fan blade, is provided with the flange fixing fan blade pressing plate of only circle after fan blade pressing plate.
The present invention directly coordinates fixing connection by arranging draw-in groove on blade-flange with the draw-in groove of fan blade root, and utilize fan blade pressing plate and flange only circle to be fixed, instead of the structure being in the past screwed fan blade, make the fixing more firm of fan blade, also simplify the structure of wind-driven generator, easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, 1 is fan blade, and 2 is generator shaft, and 3 is blade-flange, and 4 is fan blade pressing plate, and 5 is flange only circle, and 6 is nut.
Detailed description of the invention
A kind of blade screw-free fixing device for wind power generator, including blade-flange 3, fan blade 1, blade-flange 3 is fixed on generator shaft 2 by the nut 6 that front end is arranged, blade-flange 3 is provided with draw-in groove and the draw-in groove with fan blade 1 root matches, fan blade 1 rear end arranges fan blade pressing plate 4 and fixes fan blade 1, is provided with flange only circle 5 and fixes fan blade pressing plate 4 after fan blade pressing plate 4.
