本発明は風による電線の騒音を防止する電線の
風騒音防止器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wind noise suppressor for electric wires that prevents noise caused by wind on electric wires.
架設した電線に風が吹き当ると電線後方にカル
マン渦が生じ、このため風騒音を発生する。 When wind blows against an installed electric wire, a Karman vortex is generated behind the wire, which generates wind noise.
従来、電線の風騒音防止には第１図に示すよう
に電線Ｃにスパイラルロツド６を巻付けてカルマ

ラルロツド６の巻付け作業は非常に面倒で長時間
を要する等の問題点があつた。 Conventionally, wind noise in electric wires has been prevented by winding a spiral rod 6 around the electric wire C to disturb the Karman vortex as shown in Figure 1. There were problems such as it being very troublesome and requiring a long time.
本発明は上記点にかんがみなされたもので、以

にも適用し得る。 The present invention has been made in view of the above points, and an embodiment illustrating the same will be described below.
In Fig. 2, 1 is the main body of the wind noise preventer made of plastic or the like, and 2 is the wind noise preventer bar with both ends curved diagonally downward. The entire length of the noise prevention bar 2 is tightly attached to the electric wire C. Reference numeral 3 denotes a ring-shaped mounting band integrally formed approximately at the center of the wind noise prevention bar 2, with a locking protrusion 4 formed at one end and a fitting groove 5 formed at the other end. 4 is fitted and locked into the fitting groove 5, and the wind noise suppressor main body 1 is attached to the electric wire C. As shown in FIG. 3, the wind noise suppressor constructed in this manner is attached to the electric wire C alternately above and below at intervals to disturb the Karman vortex and prevent wind noise. Incidentally, the attachment band 3 is not limited to a ring-shaped one, as long as it can attach the wind noise prevention bar 2 to the electric wire C. Further, the material of the wind noise suppressor according to the present invention is not limited to plastic, but may also be metal, and the bar 2 and the band 3 may be made of different materials. Furthermore, the present invention is applicable not only to bare wires but also to covered wires.
本発明は上述のようになり、両端末部を斜め下

迅速に行え作業性が著るしく向上するなどの優れ
た効果がある。 The present invention is as described above, and the wind noise prevention bar main body 1 having the mounting band 3 integrally formed approximately in the center of the wind noise prevention bar 2 having both end portions curved diagonally downward is mounted. By making the band 3 tightly adhere to the wire C and preventing installation wind noise, it has excellent effects such as extremely easy and quick installation to the wire C and a marked improvement in work efficiency. be.
