Windproof structure of extradosed cable-stayed bridge

According to the windproof structure of the extradosed cable-stayed bridge, in the windproof structure, a plurality of linkage assemblies are arranged at the bottom of a cable-stayed bridge body, two balance weight plates are symmetrically arranged on each linkage assembly, wind direction sensors are further arranged on the linkage assemblies, rotating grooves are formed in the surfaces of the balance weight plates, and rotating shafts are arranged in the rotating grooves; and a plurality of uniformly distributed air guide blades are arranged on the rotating shaft. The cable-stayed bridge body is subjected to weight balancing and stability improving through the weight balancing plate, meanwhile, the orientation of the weight balancing plate can be automatically adjusted according to the wind direction, it is guaranteed that the weight balancing plate is parallel to the wind direction all the time, wind resistance is reduced, the weight balancing plate can be kept parallel to the wind direction all the time by
