本発明は、電線の風騒音を抑止する低風騒音装
置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a low wind noise device for suppressing wind noise from electric wires.
電線に風が吹き当つた場合には、電線後方にカ
ルマン渦が生じ、これにより風騒音が発生する。 When wind blows against an electric wire, a Karman vortex is generated behind the electric wire, which generates wind noise.
従来、この種電線の風騒音を抑止する低風騒音
装置としては、電線に装着する複数個のリング体
相互を細長連結体で一体的に連結してなり、これ
を電線に間隔を有して装着し、電線の長手方向に
直交する方向からの投影形における外形を長手方
向に沿つて変化させ、これによりカルマン渦を乱
し、もつて風騒音を抑止したものが知られる。 Conventionally, this type of low wind noise device for suppressing wind noise from electric wires has been constructed by integrally connecting a plurality of ring bodies attached to the electric wires with an elongated connecting body, which are attached to the electric wires at intervals. It is known that the electric wire is attached to the electric wire, and its external shape when projected from a direction perpendicular to the longitudinal direction of the electric wire changes along the longitudinal direction, thereby disturbing the Karman vortex and thereby suppressing wind noise.
しかしながら、上記従来の低風騒音装置の細長
連結体は１個であつたので、これを架線前の電線
に予め装着した場合には、電線の架線時の回動等
により架線後においては、その細長連結体の位置

には電線の風が吹き当る面の投影形における長手
方向に沿う外形変化が少なく、場合によつては外
形変化が生じないので、それだけカルマン渦の乱
れが少なく風騒音抑止効果が減少する欠点があつ
た。 However, since the above-mentioned conventional low wind noise device has only one elongated connecting body, if this is attached to the electric wire before the overhead line, it may be difficult to connect it after the overhead line due to the rotation of the electric line during the overhead line. The position of the elongated connecting body deviates from the planned position. In such cases, there is little change in the longitudinal direction of the projected surface of the wire on which the wind blows, and in some cases there is no change in the shape, so the disturbance of the Karman vortex is reduced and the effect of suppressing wind noise is high. There was a downside to reducing it.
一方、電線の架線後において低風騒音装置をそ
の細長連結体が所定位置に配置されるように装着
する方法も考え得るが、このようにすると、勢い
その装着作業が煩雑になる欠点がある。 On the other hand, it is also conceivable to mount the low wind noise device after the electric wire has been wired so that its elongated connecting body is placed in a predetermined position, but this method has the disadvantage that the installation work becomes complicated.
本発明は、このような欠点を改良したものであ
る。 The present invention improves these drawbacks.
これを第１図〜第３図に示した一実施例に基づ

１，２の可撓性を増大している。 The ring bodies 1 and 2 are made of rubber, plastic, or metal, and a portion thereof is provided with a vertically divided slit 4 as shown in FIG. At both ends of the slit 4, as shown in FIG. By engaging with the recess 6, the ring bodies 1, 2 can be gripped and attached to the electric wire. Further, in FIG. 2, reference numeral 7 indicates a groove formed in the ring bodies 1, 2, and this groove 7 increases the flexibility of the ring bodies 1, 2.
また細長連結体３は、リング体１，２と同様の
材料からなると共に、第２図に示す如くその個数
をリング体１，２の周方向に沿つて３個具備させ
てあり、また相互間隔は略同一としてある。 Further, the elongated connecting body 3 is made of the same material as the ring bodies 1 and 2, and is provided in three pieces along the circumferential direction of the ring bodies 1 and 2, as shown in FIG. are almost the same.
更に、細長連結体３の断面における幅と高さ

３個のうち１個の細長連結体３の一部があらわれ
るように決定してある。 Furthermore, the width and height in the cross section of the elongated connecting body 3 are such that when it is attached to an electric wire, at least one of the three elongated connecting bodies is projected from an arbitrary direction perpendicular to the longitudinal direction of the electric wire. It has been decided that a part of body 3 will appear.
尚、図において８は細長連結体３の内側面に形
成した電線把持溝を示す。 In the figure, reference numeral 8 indicates a wire gripping groove formed on the inner surface of the elongated connecting body 3.
また細長連結体３は３個に限らず２個以上であ

抑止効果は向上する。 However, according to the low noise noise device of the present invention, since the plurality of ring bodies are integrally connected to each other by the plurality of elongated connecting bodies, when this is attached to the electric wire, the electric wire will not rotate during the overhead line. Even if the wind blows on the surface, the frequency at which elongated connected bodies appear in the projected form is much higher than in conventional products, and the disturbance of the Karman vortex increases accordingly, reducing the wind noise suppression effect. improves.
