Prism refraction harmless anti-bird device for overhead transmission line

The utility model relates to the technical field of power transmission auxiliary equipment, in particular to an overhead power transmission line prism refraction harmless anti-bird device which comprises a base body, a supporting pipe is installed on the upper surface of the base body, a supporting rod is placed in the supporting pipe, and a spherical prism is arranged at the end, away from the supporting pipe, of the supporting rod. A threaded groove is formed in the spherical prism, the number of the supporting rods is multiple, and threads are arranged at the ends, away from the supporting pipe, of the supporting rods. According to the scheme, the anti-bird performance is not influenced by the natural environment and weather, the flexible support can play a role in elasticity under the windless condition, the weight of birds can enable the anti-bird device to swing, the refraction change effect of the spherical prisms is achieved, and the sound generated by mutual collision of the spherical prisms and the
