本考案は、電線に取付けられて雪が電線に付着
することを抑制できる難着雪装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-snow accretion device that is attached to electric wires and can suppress snow from adhering to the electric wires.

抑制するが、このような従来の難着雪リングは初
期段階の着雪を有効に抑制することができない。 Referring to FIG. 1, a conventional anti-snow device, a so-called anti-snow ring, will be explained. A anti-snow ring 2 is fixed to an electric wire 1 at an appropriate position in the length direction. Snow attached to the top surface of the electric wire 1 tends to move downward on the outer circumference of the electric wire 1 due to its weight,
It moves along the twist of the strands of the electric wire 1 and hits the end face of the anti-snow ring 2, thereby falling off from the outer peripheral surface of the electric wire 1, thereby suppressing the increase and growth of snow accretion. Conventional anti-snow rings cannot effectively suppress snow accretion in the early stages.

る。 In order to achieve this purpose, the anti-snow accretion device of the present invention includes a boss portion fixed to the outer periphery of the electric wire, a ring portion disposed radially outside of the boss portion, and a ring portion extending radially to connect with the boss portion. At least the ring part and the connecting part are made of an elastic material. The weight of the snow that has adhered to the ring causes the ring and the connecting part to elastically deform, and when the snow that has adhered eventually falls away from the outer circumferential surface of the ring, the ring and the connecting part tend to return to their original positions due to their elasticity. The return force generated at that time causes random vibrations in the wire, and this random vibration causes snow adhering to the wire to fall off the wire.

has 0. The anti-snow accretion device 5 is made of a heat-resistant material with a large elastic change, such as heat-resistant rubber, and therefore the ring portion 9 and the connecting portion 10 are elastically deformed.

に弾性変形するように厚み、長さ等を決定する。 As shown in FIG. 4, one connecting portion 10 is divided into two parts, and one cut portion 11 for passing the electric wire 6 into the boss portion 8 is provided. In the embodiment, the fastener 7 is used to attach the boss portion 8 to the electric wire 6, but in order to reliably prevent the occurrence of corona, the inner circumferential surface of the boss portion 8 and the cut portion 11 are partitioned. It is desirable to fix the boss portion 8 to the electric wire 6 by applying a strong and long-life adhesive to the surface, and the abutting portions of the cut portion 11 are provided with a bulging protrusion on one side and the protrusion on the other side. It is also possible to provide a recess into which the snow accretion prevention device fits to facilitate its installation.Furthermore, the entire anti-snow accretion device may be divided into two parts, and the boss portion 8, the ring portion 9, and the connecting portion 10 may be made of different materials. You can also let
Further, the thickness, length, etc. of the ring portion 9 and the connecting portion 10 are determined so that they can be easily elastically deformed by early snow accumulation.

６から離れ、落下する。 When snow blows in the direction of the arrow 14 as shown in FIG. 5, the snow adheres to the surface of the blowing side of the ring part 9, and the weight of the snow causes the ring part 9 and the connecting part to rotate in the circumferential direction. Or it twists and stores elastic energy. The two-dot chain line in Figure 5 indicates snow accumulation. When the ring part 9 is twisted by a predetermined amount, the snow on the surface of the ring part 9 separates from the ring part 9 and falls, and the ring part 9 and the connecting part 10 try to return to their original shapes due to their elastic energy, causing a predetermined vibration. This vibration propagates to the electric wire, causing the electric wire 6 to vibrate randomly. In this way, the electric wire 6
Due to the random vibration of the electric wire 6, snow adhering to the electric wire 6 separates from the electric wire 6 and falls.
なおボス部８の端面は、従来の難着雪リング２
の端面と同様に、電線６のより線のよりに沿つて
移動してこの端面に当たる雪を電線１の外周面か
ら離して落下させる役目をもつ。 Note that the end surface of the boss portion 8 is similar to that of the conventional anti-snow ring 2.
Similarly to the end face of the electric wire 1, it moves along the twist of the strands of the electric wire 6 and has the role of causing snow that hits this end face to fall away from the outer peripheral surface of the electric wire 1.

る。 As described above, according to the present invention, the anti-snow accretion device has a ring part and a connecting part, and when snow accumulates on the ring part, the ring part and the connecting part are elastically deformed, and as snow falls from the ring part, the ring part and the connecting part are elastically deformed. Vibration of the ring part and the connecting part causes random vibrations in the electric wire. In this way, snow on the wires can be caused to fall due to the random vibrations of the wires, and snow accretion on the wires can be suppressed.
