〈産業上の利用分野〉
この発明は架空送電線を支持する鉄塔の腕金部における
冠雪を防止するために、該腕金部から脚部にかけて添設
する加熱型ヒートパイプ融雪装置に関するものである。[Detailed Description of the Invention] <Industrial Application Field> In order to prevent snow from accumulating on the arms of a steel tower that supports overhead power transmission lines, the present invention provides a heating type that is attached from the arms to the legs of a steel tower that supports overhead power transmission lines. The present invention relates to a heat pipe snow melting device.
〈従来の技術とその課題〉
従来、豪雪地帯においては冬期に雪の重みにより、電柱
の支線に荷重が加わり、支線が断線したり、支線張力の
増加により電柱が傾いたり、鉄塔の脚部に損傷を与えた
りすることがある。<Conventional technology and its challenges> Conventionally, in areas with heavy snowfall, the weight of snow during winter places stress on the branch wires of utility poles, causing the branch wires to break, the poles to tilt due to increased tension on the branch wires, and the legs of the towers to be damaged. It may cause damage.
このような雪害を防止する方法として鉄塔用脚部や支線
の積雪を地熱を利用して融雪除去することが行なわれて
いる。One way to prevent such snow damage is to use geothermal heat to melt and remove snow from the legs and branch lines of steel towers.

の下部１３を地面１４内に埋めるというものであり、こ
れによって温度が５℃程度以上ある地熱をこのヒートパ
イプによって地上に輸送し、鉄塔脚部周囲の雪１５を融
雪除去しようとするものである。As shown in Fig. 3, an N pipe with both ends sealed is installed as a heat pipe 11 in the leg part 12 of the steel tower, and its lower part 13 is buried in the ground 14, thereby reducing the temperature to 5. The purpose is to transport geothermal heat of approximately 0.degree.
しかしながら、この方法は地熱がヒートパイプ内の上方

の放熱のため、該ヒートパイプの長さ（高さ）は限定さ
れ、このようなビートパイプを地上から１０〜５０１１
１もある鉄塔の腕金部までのばしたとしても睨合上の冠
雪まで融雪除去するということは期待できない。However, this method utilizes a thermal cycle 16 in which geothermal heat rises upward in the heat pipe, is cooled, and falls downward; however, because heat is dissipated from the outer surface of the heat pipe 11, the length of the heat pipe is The height (height) is limited, and such a beet pipe can be installed at a height of 10 to 5,011 cm from the ground.
Even if it extends to the arms of some steel towers, it cannot be expected to melt the snow to the top of the tower.

■ ′１４ＩＩＡ着雪の重量増と相俟って鉄塔への荷重

ある。When snow falls on the armrests of overhead power transmission line towers due to winter snowfall, this snow eventually remains as a heavy ice-like snow cap, which, combined with the increased weight of ■ '14IIA snowfall, This increases the load on the steel tower, and in the worst case scenario, there is a risk of the tower collapsing.
■ 睨合部上の冠雪の落下により腕金部の下部に位置し
ているジャンパー装置を損傷するおそれがある。■ There is a risk of damaging the jumper device located at the bottom of the armrest due to falling snow caps on the armrest.

る。Means for Solving the Problems> The present invention was obtained as a result of studies aimed at melting the snow cap on the above-mentioned steel tower arms, and is a method for solving the problems described above. To provide a heating type heat-vib snow melting equipment in which a heater is provided at the lower part of a snow melting heat pipe attached from a metal part to a leg part and both ends of which are sealed.

す。Figures 2A and 2B show the heat pipe snow melting device of the present invention having the above structure actually attached to the arm part 7 of the steel tower, and 8 in the figure indicates the heat pipe of the present invention. The snow melting device, 9 indicates the snow cap on the arm stand, and 10 indicates the power transmission line.

を防止することができるのである。As mentioned above, if a heat vibrator with a heater at the bottom is attached above and below the arm rest, even if the length of this pipe is 10111 or longer, the heating inside the pipe will be reduced. Since the inside of the pipe can be heated by connecting the device to a power source using a power cord, heat convection occurs constantly within the pipe, and by heating the surface of the heat pipe by heat convection, snow accumulation or crowning due to snowfall on the outside surface of the heat pipe can be prevented. It can prevent snow.
