The present utility model will be specifically described with reference to examples below in order to make the objects and advantages of the present utility model more apparent. It should be understood that the following text is intended to describe only one or more specific embodiments of the utility model and does not limit the scope of the utility model strictly as claimed.

Referring to fig. 1 to 4, the blade assembly for a wind power generator according to the present utility model is smart in design and mainly includes a bracket 1. The bracket 1 is provided with upright posts 11, and both ends of the upright posts 11 are provided with rotating shaft limiting pieces 12 for controlling the rotating range of the blade mechanism 3 so as to ensure the safe operation of the blades. In addition, a generator set 2 is arranged at the bottom of the bracket 1 to convert wind energy into electric energy. The output end of the generator set 2 is provided with a driving shaft 21, and the driving shaft 21 and the rotating shaft limiting part 12 are connected in a rotating way so as to ensure that wind power can be smoothly transmitted to the generator set 2.

Fig. 1-3 further illustrate the design of splice 31. A positioning hole 311 is formed through the center of the upper end surface of the splicing member 31, and the driving shaft 21 is connected to the vane mechanism 3 through the positioning hole 311. This design allows the blade mechanism 3 to rotate freely under the influence of wind force while maintaining a stable connection.

Referring to fig. 2 and 4, we can see that the outside of the splice 31 is provided with a positioning groove 312. The positioning groove 312 is designed to be connected with the fan blade 32 conveniently, the bottom of the fan blade 32 is fixedly connected with a positioning piece 321, and the positioning piece 321 can be inserted into the positioning groove 312 to realize firm connection between the fan blade 32 and the splicing piece 31.

In fig. 4, we can see that the bottom of the positioning element 321 is provided with a splicing groove 322, the splicing groove 322 is mutually clamped with the top ends of the fan blades 32, and the adjacent fan blades 32 can be mutually spliced by adopting the design, so that the overall height of the blade mechanism 3 can be flexibly adjusted according to actual use requirements.

Finally, according to fig. 2-4, a reinforcing groove 313 is formed at the bottom of the splicing element 31, and a clamping element 314 is fixedly connected to the inner side of the reinforcing groove 313. The inner side of the positioning piece 321 is fixedly connected with a reinforcing strip 323, and the reinforcing strip 323 can be mutually clamped with the clamping piece 314. The design ensures that the connection between the fan blades 32 and the splicing piece 31 is firmer, and the stability and durability of the blade assembly are enhanced, so that the whole wind driven generator can run more safely and has higher efficiency.

The working principle of the utility model is as follows:

1. the blade assembly for a wind turbine is mounted by first fitting the splice 31 over the drive shaft 21.

2. Then, the positioning piece 321 arranged at the bottom of the fan blade 32 is inserted into the positioning groove 312 arranged on the splicing piece 31, so as to realize the connection between the fan blade 32 and the splicing piece 31.

3. Meanwhile, the reinforcing strip 323 is clamped into the reinforcing groove 313, and the clamping piece 314 is arranged in the reinforcing groove 313, so that the mutual clamping between the clamping piece 314 and the reinforcing strip 323 can enable the connection between the fan blade 32 and the splicing piece 31 to be firmer.

4. Because the top of the fan blade 32 and the splicing groove 322 formed at the bottom of the positioning piece 321 are mutually clamped, adjacent fan blades 32 can be spliced with each other.
