Detailed implementation mode

[0020] In order to more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0021] As Figures 1 to 3 shown, the embodiment of the present utility model provides a wind power fan blade mounting structure, including a mounting head 1. Three uniformly distributed connecting seats 2 are fixedly arranged on the outer wall of the mounting head 1. A docking seat 3 is inserted into each connecting seat 2. A fan blade 4 is fixedly arranged at one end of each docking seat 3. A docking and mounting structure 5 is arranged between each connecting seat 2 and the fan blade 4;

[0022] The docking and mounting structure 5 includes a first connecting ring 501. The inner wall of the first connecting ring 501 is fixedly connected to the outer ring of a rotating bearing 502. The inner ring of the rotating bearing 502 is fixedly connected to the outer wall of the connecting seat 2. Three uniformly distributed first docking rings 503 are fixedly arranged on the outer wall of the first connecting ring 501. A docking post 504 is inserted into the inner wall of each first docking ring 503. The docking and mounting structure 5 includes a second connecting ring 506. Three uniformly distributed second docking rings 508 are fixedly arranged on the outer wall of the second connecting ring 506. The inner wall of each second docking ring 508 is inserted and connected to one side of the outer wall of the corresponding docking post 504.

[0023] A plurality of uniformly distributed fixing posts 507 are fixedly arranged on the inner wall of each second connecting ring 506. One end of each of the plurality of fixing posts 507 is fixedly connected to the surface of the fan blade 4. A retaining disc 509 is fixedly arranged at one end of the docking post 504. A fixing nut 505 is threadedly connected to the other side of the outer wall of the docking post 504. A limiting groove 511 is opened on the surface of each docking post 504. A limiting thread groove is opened on one side of the inner wall of the limiting groove 511. A limiting bolt 510 is threadedly connected to the inner wall of the limiting thread groove. When the limiting bolt 510 is separated from the limiting thread groove, the limiting bolt 510 is located in the limiting groove 511, ensuring the limitation of the docking post 504 and facilitating its movement, preventing the docking post 504 from falling out of the second docking ring 508. The outer wall of the limiting bolt 510 is threadedly connected to the limiting thread hole opened on the outer wall of the second docking ring 508.

[0024] The inner wall of the connecting base 2 is fixedly provided with a fixing plate 6. One side of the fixing plate 6 is rotatably connected with a docking gear disc 7. A plurality of mounting studs 8 are inserted into a plurality of through holes opened on one side of the docking gear disc 7. One ends of the plurality of mounting studs 8 are fixedly connected to the side of the other end of the docking base 3, and a mounting nut is threadedly connected to one side of the outer wall of each mounting stud 8.

[0025] Working principle: During installation, the connecting base 2 connected to the installation head 1 and the docking base 3 connected to the fan blade 4 are in a separated state. At this time, the docking post 504 is placed in the second docking ring 508 and separated from the first docking ring 503. When installing the fan blade 4, the installation head 1 is placed flat, and the fan blade 4 is lifted by a hoisting device. At this time, the docking base 3 approaches the connecting base 2. The rotating bearing 502 on the connecting base 2 is connected to the first connecting ring 501. The operator rotates the first connecting ring 501, and then aligns the first docking ring 503 with the docking post 504. The docking post 504 is inserted into the first docking ring 503, thereby ensuring the alignment of the docking base 3 and the connecting base 2.

[0026] After the mounting studs 8 connected to the docking base 3 are aligned with the docking gear disc 7 connected to the fixing plate 6, tighten the mounting nuts on the mounting studs 8. Subsequently, the operator tightens the fixing nut 505 on the docking post 504 and simultaneously tightens the limit bolt 510 on the second docking ring 508 to complete the installation of the fan blade.

[0027] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
