This invention discloses a
bird droppings prevention device for
transmission line insulators, comprising a shaft and a bird-proof cover. The bird-proof cover includes a first bird-proof cover and a second bird-proof cover. The first bird-proof cover is connected to the shaft via a first fixing component. The second bird-proof cover is staggered vertically from the first bird-proof cover and fixed to the shaft. The fixing component prevents the first bird-proof cover from rotating relative to the shaft when tightened. Compared to existing technologies, the first bird-proof cover of this invention can rotate around the shaft, thereby positioning it above the second bird-proof cover. This allows the first bird-proof cover to be mounted on the second bird-proof cover under gravity, solving the problem of increased work difficulty caused by the bird-proof cover during high-altitude operations and addressing the issue of nowhere to store the bird-proof cover during temporary disassembly. This improves efficiency and significantly reduces safety issues associated with the bird-proof cover.
