Description

[Detailed description of the invention] [Field of industrial application] This invention is designed to prevent short-circuit accidents caused by small birds entering the clamp cover to build their nests through the edge wire openings, and then snakes climbing up and crawling onto utility poles aiming for the birds. This invention relates to a cover for preventing bird and snake damage that is attached to an opening for a border line in order to eliminate the factors that cause this.

[Prior art and its problems]

Conventionally, it is known that the edge line opening of the clamp cover is provided with a lid having, for example, a zigzag line cut in the center to prevent small birds or snakes from entering the clamp cover. However, when a rim line was passed through this opening, a gap was created in the lid near the rim line, and small birds could enter through this gap, and snakes could also sneak in to catch them. .

[Means for solving problems]

Therefore, the present invention forms a cover member in which a mounting cylinder part that can be attached and detached from the opening for the edge line and a holding cylinder part that holds the edge line are connected, and an inner cover and an upper cover are provided inside the cover member. The inner cover, the upper cover, and the lid provided at the opening for the edge line of the clamp cover form a triple barrier to completely prevent birds and snakes from entering. It is an object of the present invention to provide a bird and snake damage prevention cover for a clamp cover.

[Effect]

The left and right bodies are integrally formed by connecting the mounting cylinder part and the holding cylinder part, and the cover member is attached to the opening for the rimming line of the clamp cover with the rimming line sandwiched therebetween, and the engaging pin is inserted into the cover member. Furthermore, since the right and left bodies of the cover member can be combined by engaging the locking piece and the engagement hole, installation is easy and reliable.

Further, on the inside of the cover, a triple barrier can be formed by the lid piece provided on the opening for the edge line, the inner lid provided on the mounting cylinder part of the cover member, and the upper lid provided on the holding cylinder part,
This can prevent birds and snakes from entering the clamp cover.
