本発明は、電柱の倒れを防止するための支線に葛がから
みつき巻上るのを防止するための巻上り防止具に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding-up prevention device for preventing kudzu from becoming tangled and winding up on a branch line for preventing a utility pole from falling down.
従来から山地、野原、堤防ｐよび空地などに立設された
電柱の支線には、葛や蔦などのつるがしばしばからみつ
いて巻上る。Traditionally, the branches of utility poles erected in mountains, fields, embankments, and open spaces often become entangled with vines such as kudzu and ivy.
特に葛は、その繁殖力が旺盛で、約半月程で支線を巻上
って配電線に絡１す、配電線を短絡させる。Kudzu, in particular, has a strong reproductive capacity and winds up branch lines in about half a month, causing them to become tangled and short-circuited.
そのため、配電線の短絡防止のために葛の伐採をしばし
ば行なわねばならず、葛の伐採のために多大な労力が費
やされる。Therefore, in order to prevent short circuits in the power distribution lines, kudzu must be cut down frequently, and a great deal of labor is expended in cutting down the kudzu.
この葛は、多年生のつる草でろって、成長期間は４〜１
１月でろり、山地、野原、堤防、道端、空地などにむい
て、日本全国にわたって生育して秒り、強害草である。This kudzu is probably a perennial vine, and its growth period is 4 to 1.
It is a highly harmful grass that grows all over Japan in January, growing in mountains, fields, embankments, roadsides, vacant lots, etc.
この葛は、地下茎と種子で繁殖する。This kudzu reproduces by underground rhizomes and seeds.
茎の基部は木質化する。茎はつる状になって１０ｍ以上
にもなり、盛んに分枝しながら左巻で他物にからみつく
、葉は大形であり、地下茎は地中深く横走する。The base of the stem becomes woody. The stems are vine-like and can grow to over 10 meters long, branching vigorously and twisting around other things in a left-handed manner.The leaves are large, and the underground stems run deep underground.
このような葛が支線に巻付くのを防ぐために、従来℃ま
支線の途中下方に開いた傘状の巻上り防止具を装着して
いるが、巻上り防止具の下方で複数本の葛が絡１つて前
記巻上り防止具の直径よりも大きくなると、葛は巻上り
防止具を乗越えて上方の支線に巻上り始め、葛の巻上り
防止の効果はあまり期待できない。In order to prevent such kudzu from wrapping around the branch line, an umbrella-shaped anti-curling device that opens midway down the branch line is conventionally installed, but multiple kudzu can become trapped under the anti-curling device. If the diameter of the kudzu becomes larger than the diameter of the curling-up prevention device, the kudzu will climb over the curling-up prevention device and begin to wind up on the upper branch line, and the effect of preventing the kudzu from curling up cannot be expected to be very effective.
したがって本発明の目的は、葛の支線への巻上りを確実
に防止することができる巻上り防止具を提供することで
ある。Therefore, an object of the present invention is to provide a curling prevention device that can reliably prevent kudzu from curling up onto a branch line.
