A steel cable 4 is fixedly connected to each connecting ear 3. The steel cables 4 are staggered and cross-arranged. The lower part of the steel cables 4 passes through the wind power tower body 2. A tensioning mechanism 5 is arranged at the lower end of each steel cable 4. The structural base 1 and the wind power tower body 2 form a supporting wind power tower body for wind power generation. The steel cables 4 cooperate with the tensioning mechanism 5 to tighten and reinforce the upper part of the wind power tower body 2, thereby improving the stability of the upper part of the wind power tower body 2. The entire structural steel cable 4 is arranged in the wind power tower body 2, occupies less ground, and is more beautiful.

The guide wheel 7 is arranged inside the wind power tower body 2, and the lower part of the steel cable 4 passes through the guide wheel 7. This structure uses the guide wheel 7 to change the pulling direction of the steel cable 4, so that the steel cable 4 can be horizontally extended from the wind power tower body 2.
[0026] refer to Figure 1 As shown, a through hole 8 is opened at the lower part of the wind power tower body 2 , and the steel cable 4 passes through the through hole 8 .
