Abstract
The utility model relates to a device for fixing fan blades of a wind generator without screws, which comprises a fan blade flange and fan blades, wherein the fan blade flange is fixed on the shaft of a generator through a screw cap arranged at the front end of the fan blade flange; clamping grooves are formed on the fan blade flange and matched with those formed at the root of the fan blades; a fan blade pressure plate used for fixing the fan blades is arranged at the rear end of the fan blades; and a flange stop ring used for fixing the fan blade pressure plate is arranged behind the fan blade pressure plate. In the utility model, the clamping grooves formed on the fan blade flange are directly matched and fixedly connected with those formed at the root of the fan blades, the traditional structure that the fan blades are fixed through screws is replaced by the device which fixes the fan blades through the fan blade pressure plate and the flange stop ring, so that the fixation of the fan blades is firmer, the structure of the wind generator is simplified, and the installation is convenient.
Description
Technical field
The utility model relates to a kind of fan blade fixing device of wind-driven generator, relates in particular to a kind of power-driven generator leaf fixing device without any screw.
Background technique
The fan blade of wind-driven generator is fixed on the fan blade flange by screw usually, this kind 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 cause the screw of fixing fan blade loosening, make the fracture of fan blade root.For fear of the appearance of this type of situation, just need make the fixing more firm of fan blade.
The model utility content
The utility model to provide a kind of and has been connected firmly in order to overcome the above problems, power-driven generator leaf fixing device without any screw simple in structure.
The technical solution of the utility model is: comprise fan blade flange, fan blade, the fixed by nut that the fan blade flange is provided with by front end is on generator shaft, the fan blade flange is provided with draw-in groove and matches with the draw-in groove of fan blade root, the fan blade rear end is provided with fixedly fan blade of fan blade pressing plate, is provided with flange behind the fan blade pressing plate and ends fixedly fan blade pressing plate of circle.
The utility model directly cooperates fixedly connected by draw-in groove is set on the fan blade flange with the draw-in groove of fan blade root, and utilize fan blade pressing plate and flange to end circle and fix, replaced in the past by the fixing structure of fan blade of screw, make that fixing of fan blade is more firm, also simplified the structure of wind-driven generator, easy for installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is fan blade among the figure, the 2nd, and generator shaft, the 3rd, the fan blade flange, the 4th, the fan blade pressing plate, the 5th, flange ends circle, the 6th, nut.
Embodiment
