The four legs are fixedly connected to the base 6 through the reinforcing plate 4, and the inside of the base 6 is poured with concrete. A steel mesh 8 is welded inside the base 6, and the surface of the steel mesh 8 is sprayed with corrosion-resistant paint. A cable bracket 2 is welded on the upper side of the surface of the main body 1, and the outer wall surface of the beam 9 is sprayed with a corrosion-resistant layer. The outer wall surface of the beam 9 is evenly welded with multiple reinforcing ribs, the outer wall surface of the base 6 is connected with a moisture-proof pad, and the outer wall surface of the steel cable 5 is connected with an insulating layer 3.

[0023] Working principle: First, adjust the position of the steel cable 5 to be located at the center inside the main body 1, place the ballast platform 7 at the lower center position inside the base 6, connect the steel cable 5 to the ballast platform 7, and then pour the inside of the base 6. After pouring is completed, fix the reinforcing plates at the lower ends of the four legs to the surface of the base 6 with bolts, and then insert the lower end of the support shaft 10 into the inside of the base 6 and fix it to the base 6. When encountering strong wind environment, the stress is evenly distributed to the steel cable 5, the support shaft 10 and the four legs. The overall structure is more stable and the wind resistance is greatly improved.
