A third threaded docking hole 12 is arranged at the top of the reinforcement bracket 1, and there are a plurality of third threaded docking holes 12, and the plurality of third threaded docking holes 12 are evenly arranged in a circumferential manner.
[0019] Furthermore: to facilitate improving the stability of the wind turbine column while being able to protect the threaded docking part at its bottom from rainwater, a reinforcement support frame 4 is slidably arranged on the top of the reinforcement bracket 1. There are a plurality of reinforcement support frames 4, and the plurality of reinforcement support frames 4 are evenly arranged in a circumferential manner. A driving mechanism 10 is arranged between the reinforcement support frame 4 and the reinforcement bracket 1. An arc-shaped clamping plate 5 is fixedly connected to the surface of the reinforcement support frame 4. A rubber pad 11 is fixedly arranged on the inner arc surface of the arc-shaped clamping plate 5.

A vertical reinforcement bolt 8 is threadedly connected inside the internal threaded ear plate 7. A second threaded docking hole 9 that is threadedly adapted to the vertical reinforcement bolt 8 is arranged at the top of the reinforcement bracket 1;
[0020] As a detailed description: the driving mechanism 10 includes a limit sliding groove 101 opened on the top of the reinforcement bracket 1.
