Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, the present invention provides an embodiment: a wind driven generator blade assembly comprises a wind driven generator support 1, a wind driven generator 30 consisting of a blade rotating shaft 2 and three wind driven generator blades 3, a driving gear 301 fixedly installed at one end of the blade rotating shaft 2, a generator 50 arranged in the wind driven generator support 1 and a driven gear II 501 fixedly connected to one end of a shaft of the generator 50, wherein the wind driven generator 30 is located on one side of the wind driven generator support 1, and a guide fan 40 is arranged on the other side of the wind driven generator support 1.

Further, a guiding rotating shaft 41 is arranged in the middle of the guiding fan 40, a plurality of guiding blades 4 distributed around the guiding rotating shaft 41 on the guiding rotating shaft 41 in an average circumference are arranged on the guiding rotating shaft 41, and the windward side of each guiding blade 4 faces the wind power generator blade 3.

Further, the guiding rotation shaft 41 is not parallel to the blade rotation shaft 2, and both ends of the guiding rotation shaft 41 are coplanar with both ends of the blade rotation shaft 2, but if the wind power generators 30 are installed at different heights in a mountain, both ends of the guiding rotation shaft 41 and both ends of the blade rotation shaft 2 may be made to be not coplanar, and in essence, the guiding fan 40 is directly facing to another wind power generator 30.

Further, the distance from the guide rotating shaft 41 to the end point of any guide blade 4 is smaller than the distance from the guide rotating shaft 41 to the plane formed by the center lines of the three aerogenerator blades 3 along the extension line of the center line of the guide blade 4, so that the guide blade 4 is prevented from colliding with the aerogenerator blades 3 when rotating to damage or influence the rotating speed.

Further, one end of the guide rotating shaft 41 close to the blade rotating shaft 2 is provided with a first driven gear 401, the first driven gear 401 is located on one side of the driving gear 301, and the first driven gear 401 is in transmission connection with the driving gear 301.

Further, the second driven gear 501 is located on the opposite side of the first driven gear 401 with respect to the driving gear 301, and the second driven gear 501 is in transmission connection with the driving gear 301.

Further, the driving gear 301 and the driven gear 501 are bevel gears, the driven gear 401 is a cylindrical gear, and by selecting the bevel angle of the bevel gear, the guiding rotating shaft 41 of the guiding fan 40 and the blade rotating shaft 2 can be in different angles, preferably, the angle is 5 to 30 degrees, the angle is not too large, the loss of the wind energy can be caused to a certain extent by the work done to change the wind direction, and the guiding blade 4 is shortened due to the fact that the guiding blade 4 is required to be prevented from colliding with the wind turbine blade 3 by the too large angle, and the guiding effect is weakened.

The working principle is as follows: please refer to fig. 5, fig. 5 shows an arrangement and installation manner of a wind power generation device using the wind power generator blade assembly of the present invention, it can be seen that the wind direction deflects under the guidance of the guiding fan 40, the wind power generation device which originally can not generate electricity by rotating downwards at the wind also obtains a small amount of continuous wind energy deflected, therefore, in the wind power generation device distributed in an ordered array, all wind power generation devices facing the wind direction can generate electricity by rotating downwards at any wind, although the rotating speed of some blade rotating shafts 2 is fast, the rotating speed of some blade rotating shafts 2 is slow, but the utilization rate of the device is still improved compared with the existing wind power generation device, and the idle rate is reduced.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
