A bird repeller for a high voltage transmission tower, comprising a U-shaped base (1), the U-shaped base (1) being vertically mounted with a support rod (2) and the middle portion of the U-shaped base (1) being provided with mounting holes (3), the top portion of the support rod (2) being rotatably mounted with a rotary shaft (4), side walls of the rotary shaft (4) being fixedly mounted with a plurality of rotating arms (5), the number of the rotating arms (5) being at least three, and the rotating arms (5) being symmetrically distributed around the support rod (2) as the rotation center, a head end of each rotating arm (5) being provided with a wind cup (6), the rotary shaft (4) being fixedly mounted with a reflective device (8) by means of support legs (7) uniformly mounted on the top edge of the rotary shaft (4), the center position of an upper surface of the rotary shaft (4) being provided with a platform (9), the platform (9) being mounted with an acousto-optic repeller (10). Rotatable mirror blades (64) are mounted in the wind cup (6), such that the frequency of light irradiation in a bird repelling area is increased during the rotation of the mirror blades (64), enhancing the bird repelling effect.La présente invention décrit un dispositif avifuge destiné à une tour de transmission haute tension, comprenant une base en forme de U (1), la base en forme de U (1) ayant une tige de support (2) montée verticalement sur cette dernière et la partie médiane de la base en forme de U (1) étant pourvue des trous de montage (3), la partie supérieure de la tige de support (2) ayant un arbre rotatif (4) monté rotatif sur cette dernière, les parois latérales de larbre rotatif (4) ayant une pluralité de bras rotatifs (5) montés à demeure sur ces derniers, le nombre de bras rotatifs (5) étant au moins trois, et les bras rotatifs (5) étant répartis symétriquement autour de la tige de support (2) servant de centre de rotation, une extrémité de tête de chaque bras rotatif (5) ét
