Abstract

(57) [Summary] In a conventional marker ring, since the marker piece 2a is plate-shaped, it is easily subjected to wind stress, which causes the connecting piece 2b to break due to deterioration or wear. There is a problem that the piece 2a falls off from the conductor grip 1. SOLUTION: The marker piece 2a of the marker body 2 is formed by a perforated plate, whereby the resistance of the wind applied to the marker piece is reduced, and the stress applied to the connector piece or the connecting piece is generated. This is to reduce wear and extend the life of the marker ring.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign ring used by attaching to an overhead power transmission line.

[0002]

2. Description of the Related Art Overhead transmission lines may pass through birds, especially protected bird habitats. In order to prevent birds from colliding with the overhead power transmission line,
A marking ring as shown in FIG. 3 may be attached. Further, a sign ring as shown in FIG. 3 may be attached in order to inform a person on board a helicopter or a person under construction under an overhead power transmission line of the existence of the overhead power transmission line.

This marker ring is composed of a conductor gripping portion 1 for gripping a conductor and a marker body 2 suspended below the conductor gripping portion 1. The conductor gripping portion 1 is an opening ring body having a C-shaped cross section, and the opening 1 is closed after gripping the overhead power transmission line A, and the protrusion 1a provided on one side of the opening 1a.
Is attached to the overhead power transmission line A by fitting into the recess 1b provided on the other side of the opening. Further, a marker piece mounting hole 1c for mounting a marker piece 2 described later is provided on the lower side of the conductor grip portion 1. Marker 2
Is composed of a rigid plate-shaped marking piece 2a and a rod-shaped connecting piece 2b integrally formed on the upper portion of the marking piece 2a. In this marker 2, the connecting piece 2b is attached to the conductor gripping portion 1
It is hung on the conductor gripping portion 1 by passing it through the marker piece mounting hole 1c and fixing its tip to the marker piece 2a. Reference numeral 3 is a fixed portion of the connecting piece 2b. Conductor grip 1
The marker 2 is made of plastic or the like.

In this sign ring, the sign piece 2a of the sign body 2 moves flutteringly due to the wind, so that the bird and the human are informed of the existence of the overhead power transmission line, and the bird and the human collide with the overhead power transmission line. Is to prevent.

[0005]

However, in the conventional marker ring, since the marker piece 2a is formed of a rigid plate-like member, the wind resistance is large, and when the marker piece 2a is hit by the wind, it is connected. Tensile stress and wear occur on the piece 2b. For this reason, the connecting piece 2b is broken due to deterioration or wear, which causes a problem that the marking piece 2a falls off from the conductor gripping portion 1.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a marker ring in which a marker piece is less likely to fall off from a conductor gripping portion. It consists of a sign suspended from the conductor grip,
The marker is a marker ring composed of a marker and a connecting piece, wherein the marker of the marker is formed of a perforated plate or a flexible strip.

By forming the marking piece of the marking body from a perforated plate or a flexible strip-shaped plate, it is possible to reduce the wind resistance applied to the marking piece. For this reason, it is possible to reduce the tensile stress applied to the connecting piece and the abrasion generated in the connecting piece. Therefore, the connecting piece 2b is less likely to break,
The life of the marker ring can be extended.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows a first embodiment of a marking ring according to the present invention. This marking ring includes a conductor gripping portion 1 and a marking body 2 suspended from the conductor gripping portion 1.
The marker 2 is the same as a conventional marker ring in that the marker 2 is composed of a marker piece 2a and a connecting piece 2b, but the present invention forms the marker piece 2a of the marker 2 with a perforated plate. The point is that it was done. That is, in this embodiment,
The marker piece 2a is formed in a mesh shape. In FIG. 1, the black-painted portion is the perforated portion 2c. This perforated part 2c
The marker piece 2a having a mark is generally formed of a rigid plastic plate, but it may be formed of a flexible plastic plate.

As described above, when the marker piece 2a of the marker body 2 is formed of the mesh-shaped perforated plate, the wind resistance received by the marker piece 2a can be reduced. For this reason, it is possible to reduce the stress applied to the connecting piece 2b and the wear generated in the connecting piece 2b. Therefore, the connecting piece 2b is less likely to break, and the life of the marker ring can be extended. Marker piece 2a
When the plate is formed of a flexible plastic plate, the wind resistance can be further reduced, so that the life of the marker ring can be further extended.

In the above embodiment, the case where the marker piece 2a is formed in a mesh shape is shown. However, the marker piece 2a may be a perforated plate, and the shape and size of the hole are not particularly limited. Not something to do. For example, one large round hole, 2
It may be one or more slightly larger holes such as circles, triangles and squares.

FIG. 2 shows a second embodiment of the marking ring according to the present invention. This marker ring is formed by forming the marker piece 2a with a flexible strip-shaped plate. That is, the marker piece 2a is formed of a flexible plastic plate or the like, and a plurality of cuts 2d are made at predetermined intervals in the vertical direction except the upper part. Thus, even if the notch 2d is formed in the marker piece 2a to form the marker piece 2a into a strip-shaped plate, the resistance of the wind received by the marker piece 2a can be reduced, so that the connecting piece 2b is less likely to break. The life of the marker ring can be extended. 2, the same parts as those in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted.

Although a plurality of cuts 2d are formed in the embodiment of FIG. 2, the number of cuts 2d is not particularly limited and may be one, for example.

1 and 2, the shape of the conductor gripping portion 1 and the shapes of the marking piece 2a and the connecting piece 2b of the marking body 2 are not particularly limited to the shapes of the embodiment, and for example, the shape of the marking piece 2a is not limited. The shape may be circular or the like. Also,
In FIGS. 1 and 2, since the marking piece 2a is colored red or yellow or the fluorescent coloring paint is applied to the surface of the marking piece 2a, it draws attention of birds and humans. preferable. Alternatively, a rigid or flexible metal plate having brightness may be used for the marker piece 2a to reflect light.

[0014]

As described above, the marker ring according to the present invention comprises the conductor gripping portion and the marker suspended from the conductor gripping portion, and the marker comprises the marker piece and the connecting piece. In the marker ring, the marker piece of the marker body is characterized by being formed of a perforated plate or a flexible strip-shaped plate, so that it is possible to reduce the wind resistance applied to the marker piece. . Therefore, it is possible to reduce the tensile stress applied to the connecting piece and the abrasion generated in the connecting piece. Therefore, the connecting piece is less likely to break, and the life of the marker ring can be extended.
