Abstract

(57) [Summary] [Problem] Since a conventional sign ring has a structure in which a suspending member is passed through a sign piece mounting hole, it is inevitable to use a thin string-like one, which causes deterioration of the suspending member. There is a problem in that the sign body is easily broken due to abrasion and the sign body falls off from the conductor holding body. In a marker ring including a conductor gripping body (1) and a marker body (2) suspended from the conductor gripping body (1) via a suspending member (3), the suspending member (3) is on the upper surface of the marker body (2). It is formed into a substantially inverted J shape integrally with the
The marker 2 is suspended from the conductor gripping body 1 by engaging a character-shaped suspending member 3 with the upper outer peripheral surface of the conductor gripping body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign ring that is used by being attached to an overhead power transmission line (including an overhead ground wire).

[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 body 1 for gripping a conductor, and a marker body 2 suspended below the conductor gripping body 1 via a suspending member 3. The conductor holding body 1 is an opening ring body having a C-shaped cross section formed of plastic or the like, and the opening 1 is closed after holding 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 mounting hole 1c for mounting a marker 2 described later is provided on the lower side of the conductor gripping body 1.

The marker 2 has a substantially elliptical shape and is made of a material such as a plastic plate. A hanging member 3 is integrally formed with the upper surface of the marker body 2. The suspending member 3 has a string-like shape, and the tip side is fixed to the marker body 2 after the tip side is passed through the marker body mounting hole 1c of the conductor gripping body 1. Reference numeral 4 is a fixed portion of the hanging member 3. As a result, the marker 2 is suspended from the conductor gripper 1.

In this sign ring, the sign body 2 moves flutteringly due to the wind, so that the birds and humans are informed of the existence of the overhead power transmission line A, and the birds and humans are prevented from colliding with the overhead power transmission line A. To do.

[0006]

However, in the conventional sign ring, since the sign body 2 is formed of a rigid plastic plate or the like, the resistance of the wind is large, and when the sign body 2 is hit by the wind, it is suspended. Tensile stress and wear occur on the lowering member 3. For this reason, there is a problem that the hanging member 3 is broken due to deterioration or wear, and the marker body 2 falls off from the conductor gripping body 1. That is, since it is necessary to pass the suspending member 3 through the sign body mounting hole 1c, the suspending member 3 must be a thin string-like member. Therefore, the suspending member 3 is easily broken due to deterioration or wear, and the sign body 2 is separated from the conductor gripping body 1. It will fall out.

[0007]

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 does not easily drop from a conductor gripping body, and the structure thereof is a conductor gripping body and In a marker ring composed of a marker suspended from a conductor gripping body via a suspending member, the suspending member is formed on the upper surface of the marker and integrally with it in a substantially inverted J shape, and the substantially inverted J The character-shaped suspending member is engaged with the outer peripheral surface of the upper portion of the conductor gripping body to suspend the marker body on the conductor gripping body.

If the hanging member is formed in a substantially inverted J shape, and the substantially J shaped hanging member is engaged with the upper outer peripheral surface of the conductor gripping body, the thickness and height of the hanging member can be increased. Can be arbitrarily selected. Therefore, it is possible to effectively prevent the suspension member from breaking due to deterioration or wear.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. 1 and 2 show one embodiment of the sign ring according to the present invention. This marker ring includes a conductor holding body 1 and a hanging member 3 on the conductor holding body 1.
The present invention is the same as the conventional marker ring in that it is composed of the marker body 2 suspended via the connector, but according to the present invention, the suspending member 3 is formed in a substantially inverted J shape, and the substantially inverted J shape is used. It is characterized in that the character-shaped hanging member 3 is engaged with the upper outer peripheral surface of the conductor gripping body 1.

That is, the hanging member 3 is formed on the upper surface of the sign body 2 integrally therewith in a substantially inverted J shape. In this embodiment, two substantially J-shaped hanging members 3 are formed. Two substantially inverted J-shaped suspension members 3
Is displaced with respect to the longitudinal direction of the conductor gripping body 1,
Further, the rising portions 3a face each other so that they can be attached from both side surfaces of the conductor gripping body 1. As described above, when the two hanging members 3 are provided and the rising portions 3a are opposed to each other and are attached from both side surfaces of the conductor gripping body 1, the hanging member 3 is located above the conductor gripping body 1. The effect is that it is difficult to come off from the outer peripheral surface. The marker 2 and the suspension member 3 formed integrally with the marker 2 are formed of a plastic plate or the like.

Since the substantially inverted J-shaped suspension member 3 is structured to be engaged with the upper outer peripheral surface of the conductor gripping body 1, its thickness, height, etc. can be freely selected. That is, the labeled body 2
The thickness, height, etc. of the substantially inverted J-shaped hanging member 3 may be determined in consideration of the strength of the wind received by the. Therefore, it is possible to effectively prevent the suspension member 3 from breaking due to deterioration or wear.

It should be noted that stopper walls 1d are provided at both ends in the longitudinal direction of the conductor gripping body 1 so that the substantially J-shaped hanging member 3 does not fall. Further, this conductor holding body 1 is an opening ring body having a C-shaped cross section formed of plastic or the like as in the conventional one, and the opening is closed after the overhead power transmission line A is held and one of the openings is closed. By fitting a protrusion (not shown) provided in the above into a recess (not shown) provided in the other of the openings, the overhead power transmission line A
It is to be attached to.

In order to attach the indicator ring having the above-mentioned configuration to the overhead power transmission line A, first, the conductor gripping body 1 is fixed at a predetermined position in the longitudinal direction of the overhead power transmission line A, and then the suspension member 3 is attached to the conductor gripping body 1. Engage with the upper peripheral surface. Thereby, the marker 2 can be suspended on the conductor gripper 1. Since the suspending member is formed in a substantially inverted J shape, it is easy to attach the suspending member to the outer peripheral surface of the upper portion of the conductor gripping body and does not hinder the movement of the marker. A plurality of such marking rings are attached in the longitudinal direction of the overhead power transmission line A.

Although two hanging members 3 are formed in the above embodiment, the number may be one. Further, it is preferable to form the marker 2 in a mesh shape instead of a plate shape because the resistance of the wind to the marker 2 can be reduced. Furthermore, it is preferable that the surface of the marker 2 is colored in a red or yellowish color, or that a fluorescent coloring paint is applied, in order to attract the attention of birds and humans. Also,
Light may be reflected by using a rigid or flexible metal plate having brightness for the sign body 2.

[0015]

As described above, the marker ring according to the present invention is a marker ring comprising a conductor gripping body and a marker hanging from the conductor gripping body through a suspending member. The conductor gripping body is formed by forming a member on the upper surface of the sign body and integrally with the sign body in a substantially inverted J shape, and engaging the hanging member having the substantially inverted J shape with an upper outer peripheral surface of the conductor gripping body. It is characterized in that the above-mentioned sign is suspended. Therefore, the thickness and height of the suspending member can be arbitrarily selected, so that the suspending member can be effectively prevented from breaking due to deterioration or wear, and the life of the marker ring can be extended. Further, since the suspending member is formed in a substantially inverted J shape, the work of attaching it to the outer peripheral surface of the upper portion of the conductor gripping body is easy and the movement of the sign body is not hindered.
