BIRD DAMAGE PREVENTION TOOL AND BIRD DAMAGE PREVENTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a technology for integrating a pair of wiring fitting tools by an impeller shaft and coupling rods and for fitting the fitting parts of the wiring fitting tools in the state where the impeller shaft with a number of rotary impellers mounted in a rotatable manner and the coupling rods are provided, especially in relation to a bird damage prevention tool by which a number of rotary impellers for preventing birds from perching on the wiring are indirectly fitted to the wiring via the wiring fitting tools.SOLUTION: In a bird damage prevention tool 1, end portions of an impeller shaft 3 with a number of rotary impellers 5 mounted in a rotatable manner are supported by shaft support parts 21 of a pair of wiring fitting tools 2a and 2b, thereby preventing birds from perching on wiring 7. Each of the rotary impellers 5 is formed by integrally molding a cylindrical part 51 which is mounted on the impeller shaft 3 in a rotatable manner, and three rectangular vanes 52 at an equal angle and in a radial shape. The pair of wiring fitting tools 2a and 2b is fitted to the wiring 7 in a freely swingable state by fitting parts 22 in the state where the impeller shaft 3 with a number of rotary impellers 5 mounted in a rotatable state and coupling rods 4 are provided.SELECTED DRAWING: Figure 1
