[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this utility model is a wind turbine operation and maintenance protection device for wind power generation, comprising:

[0025] The maintenance and protection mechanism includes a guide frame 14, which is U-shaped. Guide blocks 15 are symmetrically slidably provided on the upper end of the guide frame 14. A bearing seat 16 is fixed in the middle of the upper end of the guide block 15. A docking ring 17 is provided above the bearing seat 16. A columnar protrusion is provided on the lower part of the outer surface of the docking ring 17 and extends into the middle of the bearing seat 16.

[0026] The columnar protrusion connects the bearing seat 16 and the docking ring 17. The bearing seat 16 allows the docking ring 17 to rotate at multiple angles to facilitate maintenance. The docking ring 17 supports one end of the fall arrest rope and can move to multiple positions by sliding the guide block 15 within the guide frame 14 to meet the needs of multi-position maintenance.

[0027] The maintenance and protection mechanism also includes a mounting bracket 11, which is threadedly fixed to the upper edge of the outer surface of the rudder;

[0028] Mounting bracket 11 provides a structural installation environment and ensures structural stability during installation.

[0029] The upper end of the mounting bracket 11 has threaded posts 12 at equal intervals on both sides, and the upper end of the threaded posts 12 is fixedly provided with mounting posts 13, which are rotatably connected to the bottom end of the guide bracket 14 on both sides.

[0030] The mounting post 13 connects and fixes the guide frame 14 and the mounting frame 11 with the help of the threaded post 12. The threaded connection method makes it easy to disassemble and assemble the structure.

[0031] Working principle: The mounting frame 11 and the guide frame 14 are pre-installed and fixed by the threaded column 12. A guide block 15 is slidably installed in the upper end of the guide frame 14 and then connected to one end of the fall protection rope through the docking ring 17. The other end of the fall protection rope is connected to the human body. At this time, when the maintenance personnel are performing maintenance on the wind turbine, the maintenance personnel act on the guide block 15 while moving. By sliding the guide block 15 in the guide frame 14, the maintenance personnel can move to multiple positions to complete the maintenance of the wind turbine.

[0032] This solution allows for multi-position movement of wind turbines without disassembling the ropes, reducing operational risks, improving performance, and meeting requirements.

[0033] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0037] The columnar protrusion secures the wireless emergency alarm 23 to the sliding block 22.

[0038] A sleeve post 24 is fixedly provided at the middle of the bottom end of the sliding block 22 and is fitted into the opening at the bottom end of the inner wall of the sliding groove 21.

[0039] The interlocking of the sleeve 24 and the opening restricts the structure of the sliding block 22, thereby ensuring the stability of the wireless emergency alarm 23 during installation.

[0040] The upper end of the sliding block 22 is close to the upper end of the inner wall of the sliding groove 21, and a rectangular opening protrusion is provided in the middle of the upper end of the sliding block 22.

[0041] The rectangular protrusions facilitate gripping the sliding block 22 to apply the force required for assembly and disassembly.

[0042] Working principle: The wireless emergency alarm 23 is pre-installed by fitting the columnar protrusion with the sliding block 22. At this time, the sliding block 22 is held by the rectangular opening protrusion, and the lower end of the sliding block 22 is placed into the sliding groove 21. Then, an inward force is applied, and the sliding block 22 is fixed by fitting the column 24 and the opening. When the maintenance personnel fall, they can use the wireless emergency alarm 23 at their location to call for help.

[0043] This solution, while providing protection for maintenance personnel as described above, can also ensure their timely rescue, further enhancing protection capabilities and meeting the required needs.
