Compared with the prior art, the invention has the beneficial effects that:
1. this fan blade that wind power generation used, through being equipped with first wind blade, second wind blade and third wind blade, three blade size is different, all blades can be blown and rotate together when wind-force is big, a plurality of wind blades generate electricity together, because second wind blade and third wind blade are littleer first wind blade relatively, when the first wind blade can't be blown to the undersize of wind-force, second wind blade or third wind blade can continue to rotate and generate electricity for the device, the generating efficiency of device has been improved, and the condition of unable power supply when having overcome wind-force not enough.
This fan blade for wind power generation, through being equipped with first wind blade axle, second wind blade axle and third wind blade axle, because connecting cylinder inside is the fretwork, the third wind blade axle cup joints in the second wind blade axle, and the second wind blade axle cup joints in first wind blade axle again, all can not influence second wind blade axle and third wind blade axle when first wind blade axle does not rotate, and three wind blade axles use the method of cup jointing to connect, make them not only link together but also each not influence.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a cross-sectional view of a first wind blade of the present invention.
In the figure: 1. a first wind blade; 2. a second wind blade; 3. a third wind blade; 4. a support bar; 5. a third wind blade shaft; 6. a second wind blade shaft; 7. a first wind blade shaft; 8. a connecting cylinder; 9. the blade assists the rotating machine.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-2, an embodiment of the present invention is shown: the utility model provides a fan blade that wind power generation used, including bracing piece 4, the top of bracing piece 4 is provided with connecting cylinder 8, the back of connecting cylinder 8 is provided with supplementary commentaries on classics machine 9 of blade, the output of connecting cylinder 8 is provided with first wind blade axle 7, the one end of first wind blade axle 7 is provided with second wind blade axle 6, the one end third wind blade axle 5 of second wind blade axle 6, the outside of first wind blade axle 7 is provided with first wind blade 1, the outside of second wind blade axle 6 is provided with second wind blade 2, the outside of third wind blade axle 5 is provided with third wind blade 3.
Further, the area of first wind blade 1 is greater than second wind blade 2, and the area of second wind blade 2 is greater than third wind blade 3, and first wind blade 1, second wind blade 2 and third wind blade 3 run through respectively and set up on first wind blade axle 7, second wind blade axle 6 and third wind blade axle 5, and three wind blade has improved the generating efficiency of device, has overcome the unable difficulty of generating electricity of wind-force undersize.
Further, the connecting cylinder 8 is movably connected with the first wind blade shaft 7, the second wind blade shaft 6 is sleeved in the first wind blade shaft 7, the third wind blade shaft 5 is sleeved in the second wind blade shaft 6, and the three wind blades can be connected together and can operate independently.
