The operator can easily rotate the rotating shaft 7 through the handle 24, which improves the convenience of operation.

[0053] Working principle

[0054] Base installation: When installing the wind turbine support and fixing device, firstly, the four sets of base plates 11 of the base 1 in Example 1 are spliced ​​together by side blocks 13 and side grooves 12. Side sealing strips 18 are inserted into the side grooves 12 at the splicing points, and cross sealing strips 15 are installed in the bottom cross grooves 14. Then, the embedded rods 16 at the bottom of the four sets of base plates 11 are fixed with screws, and sealing gaskets 17 are installed between the embedded rods 16 and the base plates 11. Finally, the embedded rods 16 are inserted into the foundation for fixing, thus completing the installation of the base 1. This process improves the waterproof sealing performance of the base 1 and ensures the stability of the base 1.

[0055] Connection between the air duct and the base: Align the air duct 2 with the base 1, and insert the plug 20 on the air duct 2 into the annular insert rail (slot 19) of the base 1 to initially achieve the plug-in connection between the air duct 2 and the base 1. The four sets of fixing rods 3 are located inside the annular insert rail, providing a basis for subsequent fixing.

[0056] Duct fixing: After the duct 2 is initially inserted into the base 1, the operator can operate the handle 24 in embodiment 3 to rotate the rotating shaft 7 (based on the structure of embodiment 1). The rotating shaft 7 drives the gear 8 to rotate. Since the gear 8 meshes with the rack 9 on the movable frame 6, the rotation of the gear 8 will drive the movable frame 6 to slide along the fixed plate 5. During the sliding process, the positioning block 10 on the movable frame 6 will gradually insert into the positioning hole 4 on the fixed rod 3, thereby firmly fixing the duct 2 to the base 1. During this process, the guide rod 23 in embodiment 3 plays a good guiding and limiting role for the sliding of the movable frame 6, ensuring that the positioning block 10 can be accurately inserted into the positioning hole 4.

[0057] Operation and maintenance: During the operation of the wind turbine, if it is necessary to operate or maintain the components inside the wind duct 2, the operation door 21 in embodiment 2 can be opened (the operation door 21 is movably connected to the wind duct 2 via a hinge). After the operation is completed, the operation door 21 is closed. Since a sealing strip is provided between the operation door 21 and the sealing cover 22, the sealing effect of the sealing cover 22 can be guaranteed, protecting the components inside the wind duct 2.

[0058] The overall structure is stable: the rib plate 25 in embodiment 1 enhances the structural stability of the fixing plate 5 inside the wind duct 2; the fixing ring 26 on the outer wall of the wind duct 2 cooperates with the groove block of the base 1, further improving the stability of the connection between the wind duct 2 and the base 1, ensuring that the entire wind turbine support and fixing device can operate stably in various environments, and providing reliable support for the wind turbine.
