[0015] Mark explanation:

[0016] 1 wind power gear box, 2 flange plate, 3 filter cylinder, 4 installation cavity, 5 supporting ring, 6 spring, 7 filter core, 8 rotating shaft, 9 rotating disc, 10 clamping plate, 11 handle, 12 fastening bolt. Specific implementation

[0017] The present application will be further described below in combination with the drawings.

[0018] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and specific implementation. It should be understood that the specific implementation described herein is only used to explain the present application, and is not used to limit the present application.

[0019] Reference Figures 1-3 A wind power gear box convenient for replacing air filter core, comprising a wind power gear box 1, a flange plate 2 is arranged at the installation opening of the wind power gear box 1, the flange plate 2 is connected with a filter cylinder 3 through bolts, a plurality of installation cavities 4 are arranged in the filter cylinder 3, a supporting ring 5 is arranged at the bottom of the installation cavity 4, a spring 6 is arranged on the supporting ring 5, and a filter core 7 is placed on the spring 6; a rotating shaft 8 is arranged at the top center of the filter cylinder 3, a rotating disc 9 is arranged on the rotating shaft 8, a plurality of clamping plates 10 are arranged at the outer ring of the rotating disc 9, the clamping plates 10 correspond to the installation cavities 4 one by one, the clamping plates 10 rotate to the filter core 7 along with the rotating disc 9, the filter core 7 is lifted up under the action of the spring 6 and is limited under the action of the clamping plates 10, so that the filter core 7 is fixed. Specifically, the filter core 7 is placed in the installation cavity 4, the bottom of the filter core 7 is placed on the spring 6, and then the rotating disc 9 is rotated, so that the clamping plates 10 press on the top of the filter core 7, and the filter core 7 is lifted up under the action of the spring 6, so that the filter core 7 can be fixed; when it is needed to be disassembled, the rotating disc 9 is rotated again, the clamping plates 10 are rotated away from the filter core 7, and then the filter core 7 can be taken out, which is convenient and fast.
