Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing a power pole or a power transmission tower from being short-circuited due to nesting of birds.

[0002]

2. Description of the Related Art In recent years, birds often nest on distribution poles and transmission towers. In power distribution poles, there are many arms suitable for nesting, and in power transmission towers, there are many spaces suitable for nesting. Such a portion is a portion where the transmission line is subjected to a jumper process, and the high-voltage transmission line is relayed through various connection fittings.

[0003] By the way, in the suburbs of cities, unlike in the case of mountainous areas, metal waste such as plastic and wire are often used as nesting materials. Therefore, when nesting is performed near the exposed portion of the high-voltage electric wire as described above, the power transmission lines are short-circuited by the metal material, and an unexpected accident occurs.

[0004] Therefore, in the related art, a barbade is formed by laying nets of fishing lines or wires in places where birds are likely to nest, so as to block the invasion and nesting of birds. Various measures have been taken to prevent birds from nesting by disturbing the sense of direction of birds by attaching such a thing and preventing short-circuiting of transmission lines due to nesting.

[0005]

However, a wind turbine provided with a magnet has a limit in magnetic force, and cannot provide a wide range of effects. In addition, the method of using the grease or the wire is complicated in installation work, and the effect of preventing bird damage cannot be expected much. In the case of power transmission towers in particular, it is almost impossible to build a reliable barricade due to the large nesting space. In addition, such complicated installation work is extremely dangerous because the work is performed at a high place.

[0006] The present invention has been made in view of the above problems, and has as its object to provide a simple and extremely effective method for preventing bird damage.

[0007]

That is, according to the present invention, there is provided a method for preventing a short-circuit accident or the like in a power distribution pole (1) or a power transmission tower (11) due to nesting of birds. (1) A flat member (20) of any shape having high reflectivity is movably attached to an appropriate place of the power transmission tower (11), and the reflected light threatens a bird.
It is characterized by hindering nesting. Such a method is easier to install than conventional methods for preventing bird damage and can be realized at low cost.

According to a second aspect of the present invention, an eccentric weight (22) is mounted on the flat member (20). Flat member (20)
By attaching the weight (22) that decenters the center of gravity to the flat member (20), the flat member (20) loses balance and moves more irregularly, so that the effect of threatening birds by the reflected light is improved.

Further, according to the present invention, the flat member (20) is a compact disk (CD-ROM).
ROM). The CD-ROM is excellent in mechanical strength, weather resistance, insulating properties, etc., as well as reflective power, and is very suitable. In addition, by using a CD-ROM or a defective CD-ROM that is no longer needed, it can be effectively used for recycling.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a flat member having a metallic luster or luster and having a high reflectivity to light is freely attached to a distribution pole or a power transmission tower where birds are likely to nest.
In this method, birds are intimidated by reflected light when they move and are driven away.

As the flat member having high reflectivity, various members such as a mirror-finished aluminum plate or a stainless steel plate, or a metal-plated resin material can be used.
Since it is necessary to leave it outdoors for a long period of time, those having excellent mechanical strength, weather resistance (heat resistance, cold resistance) and excellent insulation properties from the viewpoint of safety are preferred. Therefore, in the present embodiment,
As a member satisfying the above conditions, a compact disc 20
(Hereinafter referred to as CD-ROM).

Since the CD-ROM 20 is made of polycarbonate, it has excellent mechanical strength, weather resistance and insulation properties.
In addition, it has an advantage that it is easy to move because it is lightweight. Moreover, since the CD-ROM 20 can obtain seven colors of reflected light such as interference fringes depending on the reflection angle, it is an optimal member for threatening birds.

The embodiment will be described below with reference to FIGS.

FIG. 1 shows an embodiment for preventing nesting in a power distribution pole 1. FIG. 1 (a) is a front view, and FIG. 1 (b) is a plan view. Is the case. In FIG. 1, reference numeral 1 denotes a telephone pole, reference numeral 2 denotes an air (vacuum) switch, reference numeral 3 denotes an arm for mounting the switch 2, and reference numeral 5 denotes a distribution line to the arm 3 (that is, the electric pole 1). Reference numeral 4 is a champer wire for relaying.

In the case of a hugging column, nesting is often performed using the upper surface of the switch 2 and the two left and right hoops 3, 3 (broken line A in FIG. 1). Therefore, the CD-ROM 20 is attached by using the extra length of the bolt 6 which is located near the nesting point A and attaches the distribution line strap 5 to the arm 3.

In this embodiment, the CD-ROM 20 is adhered to the tip of an elongated support plate (or rod-shaped body) 21 having flexibility and excellent weather resistance (for example, made of black polyethylene). The other end of the support plate 21 can be easily attached to the extra length of the bolt 6 by fixing it with the nut 7.

Further, as shown in FIG.
The weight of the CD-ROM 20 is set at a predetermined position, and the center of gravity of the CD-ROM 20 is decentered, so that the balance of the CD-ROM is lost.
20 will move violently in response to crosswinds, etc.
The reflected light at that time can make the threat to birds more effective.

FIG. 2 shows a case where the present invention is applied to a torii pillar.
Also in this case, the bolt 6 for attaching the strap 5 to the arm member 8 can be used as described above. This embodiment uses a CD-
This is a method in which the ROM 20 is hung by a string 23 having weather resistance. Also in the case of such a suspension type, the CD-ROM 20 is easily dislodged by losing its balance by mounting the weight 22, which is effective against threats.

FIG. 3 shows a case in which the present invention is applied to an overhead ground wire cap mounting column (concrete pillar), and a CD-ROM 20 is attached by tying a string 23 to a safety rope hook 10 at the tip of an overhead ground wire cap 9. It is a method of hanging.

Next, an embodiment for preventing nesting in the power transmission tower 11 will be described. In the case of a power transmission tower, there are many places where nests can be nested due to the large space. However, as shown in FIG. 4, places which are considered to be necessary in the present invention, for example, the main arm 12 and the arm 1
3. Any number of attachment bolts can be freely attached using the extra length of the attachment bolts such as the arm suspension material 14, the gusset plate 15, and the like. In this figure, the right half is assumed to be a tension tower, and the left half is assumed to be a suspension tower.In the case of the right tension tower, the jumper wire is pulled down to the ground side, so as shown in the figure. At the end of the arm member main material 12, a CD-
The ROM 20 can be hung. However, in the case of the left suspension tower, the electric wires are hung on an insulator suspended at the tip of the arm member main member 12, so that the strings 23 like the tension tower are used.
Is difficult, and as shown in the figure, the hanging by the support plate 21 is preferable.

FIG. 5 is an enlarged view of a mounting portion of the CD-ROM 20. FIG. 5A shows a suspension using the support plate 21. Further, in the case of a tension-type steel tower, the string 23 may be used as a suspension, as shown in FIG.

As described above, in this embodiment, in any case, the CD
The installation work is extremely simple, since no special parts or tools are required for mounting the ROM 20; In addition, since the suspended CD-ROM 20 can sufficiently fulfill its function even if it is defective or unnecessary, the waste can be effectively used as a part of recycling, which is extremely economical.

[0023]

As described above, according to the first aspect of the present invention, a flat member having an arbitrary shape having a high reflectivity is movably attached to an appropriate position of a power distribution pole or a power transmission tower, and the reflected light is used. Since the birds are threatened to hinder nesting, installation is easier than conventional bird harm prevention methods, and special parts and tools for installation are not required, so it can be realized at low cost. .

According to the second aspect of the present invention,
Since the weight for eccentricity was attached to the flat member,
The flat member whose balance has been disturbed by this weight becomes more free to move, and the reflex action becomes remarkable, so that the threatening effect on birds is improved.

According to the third aspect of the present invention, a compact disk (CD-R) is used as the flat member.
