[0007]
DETAILED DESCRIPTION OF THE INVENTION
According to the bird and animal damage prevention device of the present invention, since the protrusion is provided on the outer periphery of the tubular body, this protrusion becomes an obstacle for birds and small animals, and it becomes difficult to be caught on the wire or to travel on the wire. As a result, birds and small animals do not get close to the wire. And in particular, since this projection has a trunk portion and a branch portion, even if this projection is installed relatively sparsely with respect to the tubular body, the branch portion becomes an obstacle between the installation positions of the projection, and the expected A sufficient effect can be secured. In addition, if the protrusions are placed loosely, the number of protrusions arranged per unit length can be reduced, so that it takes less time to manufacture the bird and animal damage prevention device, and the trunks are densely arranged. There is an advantage that the bird and animal damage prevention tool is lighter than the case, and the load applied to the electric wire is reduced.
Moreover, since the collar part is provided in the outer periphery of the tubular body, the effect which prevents the traffic of a small animal is still higher. In addition, since a plurality of protrusions project from the outer edge of the buttocks, the attachment of the plurality of protrusions can be completed simply by attaching a single collar to the tubular body, making it easy to manufacture bird and animal damage prevention tools. become able to.
Furthermore, since the branch portion is an obstacle at different height positions, it becomes extremely difficult for birds to be caught.
[0008]
Further, according to the wildlife prevention tool according to claim 2, since the protrusion is a flexible protrusion, it can be easily bent when subjected to an external force, and even if an operator touches it with his / her hand, the hand is damaged. In addition, even if a bird or the like comes into contact, it will not be hurt. Moreover, even if the bird and animal damage prevention tool falls as the electric wire is cut for some reason, the flexible projection does not damage the object at the dropping position.
[0009]
By the way, if it is a flexible protrusion, there is a possibility that it will be stepped on by birds and the like. In such a case, there is a possibility that the expected effect will not be obtained with the conventional protrusion, but in the case of the bird and animal damage prevention device of the present invention When the trunk is stepped down, the branch that turned to the side is turned upward, so that the bird is uncomfortable and the effect of dissipating the bird is not lost.
[0011]
In addition to the electric power supply wires, the bird and animal damage prevention device of the present invention can be mounted on a variety of wires wired overhead such as various communication cables and support wires stretched between power poles. is there.
