The accommodating cavity 23 has a partition structure 30 to divide the accommodating cavity 23 into a plurality of accommodating sub-cavities 231. The plurality of accommodating sub-cavities 231 are used to accommodate different fillers.

[0027] The fixing device for wind turbine generator provided by the embodiment comprises a first cylinder 10 and a second cylinder 20. The first cylinder 10 has a first opening 11 at the top end. The first cylinder 10 has a first bottom wall 13. A generator connecting part 12 is arranged on the first bottom wall 13. The bottom of the wind turbine generator can extend into the first cylinder 10 through the first opening 11 and be fixed on the first bottom wall 13 of the first cylinder 10 through the generator connecting part 12, so as to facilitate the connection and fixation of the first cylinder 10 and the wind turbine generator. The second cylinder 20 is arranged on one side of the first cylinder 10 and detachably connected with the first cylinder 10. The second cylinder 20 is provided with a second bottom wall 21 and a second opening 22. The second cylinder 20 has a containing cavity 23 communicating with the second opening 22. In this way, the filler can be placed in the containing cavity 23 through the second opening 22. Then, the second cylinder 20 and the filler can provide loading force for the first cylinder 10 when the filler is placed in the second cylinder 20. In this way, the filler in the containing cavity 23 of the second cylinder 20 can provide stable loading force for the first cylinder 10, thereby ensuring the structural stability of the first cylinder 10. The containing cavity 23 is provided with a separation structure 30. The separation structure 30 can divide the containing cavity 23 into a plurality of containing sub-cavities 231. The plurality of containing sub-cavities 231 can contain different fillers. In this way, the number or position of the fillers can be adjusted. The fillers can be filled in any containing sub-cavity 231. In addition, the number of the fillers can be adjusted to determine different loading forces. In this way, the stability of the wind turbine generator connected with the first cylinder 10 can be ensured. Moreover, the first cylinder 10 and the second cylinder 20 can be installed on the roof, which facilitates hoisting and improves the practicability of the fixing device for wind turbine generator.

In addition, the fillers can be placed in the accommodating sub-cavities 231 of the second cylinder 20, which can ensure the structural stability of the first cylinder 10. In addition, the snap-fit ​​structure 40 is provided to snap-fit ​​one side of the partition 31 to the inner side wall of the second cylinder 20, so that the partition 31 can be installed in the accommodating cavity 23 and the partition 31 can be easily removed and installed.

The snap-fit ​​groove is arranged on the side wall of the second cylinder 20. When the snap-fit ​​block 41 is in the extended position, the snap-fit ​​block 41 is snap-fitted with the snap-fit ​​groove. When the snap-fit ​​block 41 is in the retracted position, the snap-fit ​​block 41 is separated from the snap-fit ​​groove. By adopting the above structure, a accommodating groove is provided on one side of the partition 31, and the snap-in block 41 can be telescopically inserted into the accommodating groove, so that the snap-in block 41 has an extended position extending out of the partition 31 and a retracted position retracted into the accommodating groove. A snap-in groove is provided on the side wall of the second cylinder 20. When the snap-in block 41 is in the extended position, the snap-in block 41 can pass through the accommodating groove and extend into the snap-in groove, thereby enabling the snap-in block 41 to be snap-fitted with the snap-in groove, thereby facilitating the separation of the partition 31 from the second cylinder 20.
