Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird damage preventive tool for protecting facilities such as overhead power distribution lines, overhead power transmission lines, and substations from bird damage accidents.

[0002]

2. Description of the Related Art Small birds such as pigeons and sparrows mainly use overhead power distribution lines, overhead power transmission lines, or electric wires of substations, etc., and large birds such as crows and hawks use electric lines and substations. Equipment such as
For example, arms and transformers installed on the pillars are used as perch,
It is also known to make a nest in a part of it. If birds stay in the upper part of the pillar or make nests in the upper part of the pillar, an accident such as short-circuiting of the electric line will occur, so it has been attempted to use a warning sound generator, a light generator, etc. as a defense against bird damage. There is.

As a means for protecting the electric line from damage by birds, it has been attempted to attach a balloon having an eyeball pattern or suspend flags at appropriate intervals. (For example, the actual development Sho 53-15159
(Gazette No. 6) As protective means for electric line equipment, it has been attempted, for example, to attach a protective cover to the connection portion of the electric wire, or to attach a protective cover to the insulator that bundles the electric wires across the insulator from the electric wire. .

[0004]

Most of the conventional bird damage prevention devices have some effect at the beginning of use, but there is a problem that they are not effective for long-term use. For example, at the beginning of the installation of the alarm sound generator, etc., birds could not approach, but the clever crow quickly became accustomed to the alarm sound and remained on the electric line. In order to find nesting on the pillar, there is a problem that the electric line has to be regularly patrolled, and when the nesting is found, it is necessary to climb to the pillar and remove it so as not to damage the electric line. There was a problem that didn't happen.

There is a problem that any bird damage prevention means and bird damage prevention equipment are not suitable for long-term use. Therefore, the present invention was carried out by investigating an electric line used by birds as a retaining tree, and found that many birds have a stable electrical line facility according to their size as a retaining tree, and when they retain or fly away, the wings are flapping. Focusing on the use of an electric line facility without obstacles as a perch, the present invention has led to the invention of a bird damage prevention device that is an unstable perch and has its properties reversed.
