BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called insulator between a plurality of pole equipment such as a transformer installed above a utility pole, and a fastening insulator attached to a pole of a utility pole to secure a transmission line. The present invention relates to a nesting preventive device for preventing birds from flying and nesting in places where nesting is likely to occur, such as between the nests.

[0002]

2. Description of the Related Art Conventionally, birds can easily nest on the upper part of a telephone pole, for example, between pole mounted devices such as a plurality of transformers, or between a stranded insulator attached to a crosspiece and an edging wire. Known as a place.

[0003]

The present situation is that birds are left unprotected without any nesting prevention measures, although there are places where birds can easily nest, as described above. They nested and often caused distribution line accidents. Therefore, an object of the present invention is to provide a nesting preventive device that prevents birds from nesting by attaching the birds so as to cover the upper surface of the place where the birds easily nest.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, a nesting prevention device according to the present invention is mounted on a utility pole or a brace attached to a utility pole so as to cover an upper surface of a place where birds easily nest. A nesting preventive device, comprising a plurality of barrier rods having a predetermined length projecting radially and slightly downward from a front surface of an attachment band attached to the electric pole or the crosspiece. In this way, by attaching the mounting band to the utility pole or arm bar so that the barrier rod group covers the top of the place where birds easily nest, it is possible to nest tree twigs that birds have carried for nesting. Even if it is dropped from above, the upper surface of the barrier rod group slides down and is blocked, thereby preventing nesting.

Each of the barrier rods 2 is formed of a synthetic resin material into a rod shape having a diameter of about 10 mm and a length of about 400 mm, and has a base end portion fixed to the front surface of the front half 1 a of the mounting band 1 via the mounting member 7. .

[0007] The nesting prevention device A thus constructed is shown in FIG.
As shown in the figure, three transmission lines W fastened to the vertical rod V
1, W2, W3, a predetermined distance from the transmission line W2 such that the barrier rod 2 covers the upper surface of the second transmission line W2 from the top, particularly the upper surface between the insulation insulator I and the edging wire K. Then, the mounting band 1 is attached to the vertical rod V and fixed. As described above, the upper surface between the terrestrial insulator I and the edging wire K of the second transmission line W2 from the top is covered with the nesting prevention tool A in general because of the habit of birds, the uppermost terrestrial insulator I The nesting is not performed on the upper surface between the arresting line K and the second or third insulator I and the arranging line K. This is because the third upper surface can be covered by covering the upper surface between the second insulation insulator I and the edging wire K with the nesting prevention tool A. The nesting preventive device A is attached to the arresting insulator I as shown in FIG. 4 because each of the barrier rods 2, 2... The upper surface between the wrapping line K is covered, and even if a tree twig or the like that a bird has carried to nesting falls from above, it is blocked by the barrier rods 2 and the barrier rods 2 Slide down the top. Therefore, nesting is not performed.

The nesting prevention tool A1 shown in FIG. 5 is installed horizontally on a utility pole P as shown in FIGS.
This is for covering the upper surface between the transformers T. This area is also where nesting is easy. This nesting prevention tool A1 is a mounting band 1 that is wrapped around a telephone pole P and fixed.
An arcuate mounting member 7a is fixedly mounted on the front half surface of the device, and a plurality of (six) barrier rods 2 are fixed to the mounting member 7a. These barrier rods 2, 2,... Are also protruded radially and slightly inclined downward. Then, as shown in FIG. 6, the mounting band 1 is circulated around the utility pole P at a predetermined distance from the upper surfaces of the transformers T, T, and a key-shaped hook 8 at one end is provided with a plurality of through holes 9 formed in the mounting band 1. , 9... Are attached by being hooked to a predetermined one of the through holes 9. As shown in FIGS. 7 and 8, the barrier rods 2 of the nesting preventer A1 thus mounted cover the transformers T, T and the upper surface between the transformers T, T, so that birds can be twigs of trees. Even if it is dropped from above, it is blocked by the barrier rods 2 and slides down the upper surface, thereby preventing nesting.

[0009] The nesting prevention tool A2 shown in FIG. 9 is a telephone pole P for retaining the end of the transmission line W as shown in FIGS.
It is used by being attached to. This nest prevention tool A
Reference numeral 2 denotes a plurality of (three) arc-shaped mounting members 7a fixedly mounted on the front half surface of a mounting band 1 to be wrapped around and fixed to a utility pole P similarly to the nesting prevention tool A1 shown in FIG. The barrier rod body 2 is fixed. These barrier rods 2
Are also projected radially and slightly inclined downward. As shown in FIG. 10, arms B, B are mounted horizontally and parallel to the upper part of the utility pole P with the utility pole P interposed therebetween, and a pair of upper and lower support brackets S are formed on the arms B, B. , S are assembled such that their ends cross each other, and at the crossed ends, a retaining insulator I is retained via a connecting bolt C, and an end of the transmission line W is moored to the retaining insulator I. In this case, the tip intersection of the support fittings S, S is a place D where nesting is easy.
