かかる積雪ｖＪ重を解消するものでおる。It is well known that water columns and concrete columns that support electric wires and cables are reinforced against wind pressure loads and horizontal loads by installing branch lines, but when there are multiple tanks of snow, A large load is applied to the branch line due to the settling force of snow, which can stretch the branch line and, in the worst case scenario, cause it to break or cause the pole to collapse. Conventionally, there is a device to prevent such inconvenience, for example,
No. 0-152756. In this device, the lower end of the heat pipe is buried deep underground so that it faces the high-temperature area generated by geothermal heat, and the upper end of the heat pipe is fixed along the branch line of a utility pole, allowing the heat pipe to transfer geothermal heat to the branch line. By transporting the snow to the surrounding area and melting it, the snow load on the branch line is eliminated.

埋設のための掘削工事に特別な設備や長い工期を要する
ことになり、これが原因で全体としてのコストが高騰す
る問題があった。By the way, a heat pipe is a relatively thin tubular body with a small surface area per unit length. Therefore, in order to generate the necessary and sufficient amount of heat by 1 q, the end of the heat pipe must be inserted into the tube where the temperature is sufficiently high. In places where the temperature is not particularly high, it is necessary to increase the insertion length of the heat pipe to increase the surface area of the part used for heat input. However, with the above-mentioned conventional equipment, in order to obtain enough heat to melt snow on the branch line, it is necessary to bury the heat pipe deep underground to increase the length of the buried part of the heat pipe. The problem was that the excavation work required special equipment and a long construction period, which caused the overall cost to rise.
この発明は上記の事情を背景としてなされたもので、施
工が容易であって安価な支線の融雪装置を提供すること
を目的とするものである。This invention was made against the background of the above-mentioned circumstances, and an object thereof is to provide a branch line snow melting device that is easy to construct and inexpensive.
この発明は、上記の目的を達成するために、ヒートパイ

徴とするものである。In order to achieve the above object, the present invention forms the lower end side of the heat pipe in a spiral shape, buries the spiral part in a high temperature heat collecting part underground, and It is characterized in that the upper end side extending above the ground is fixed along with a branch line stretched diagonally between the utility pole and underground.

面積が広くなるから、ヒートパイプを特に深く埋設せず
に、融雪に必要充分な熱量を得ることができる。In the device of this invention, during the snowy season, the temperature of the spiral buried part of the heat pipe becomes higher than that of the part along the branch line, so the lower end of the heat pipe becomes the heating part underground, whereas Since the upper end of the side serves as the cooling section, the geothermal heat applied to the heating section is carried to the cooling section and radiated, and as a result, the snow around the branch line is melted. In this invention, the underground portion has a spiral shape and has a large surface area per unit depth, so it is possible to obtain sufficient heat for snow melting without burying the heat pipe particularly deep.

を防止するために断熱構造とされている。FIG. 1 is a schematic diagram showing one embodiment of the present invention, in which a branch line 2 for reinforcing a telephone pole 1 supporting communication cables and electric wires is stretched diagonally. is made by twisting, for example, three or four mild steel wires, one end of which is fixed near the top of the utility pole 1, and the other end fixed to an anchor 3 buried underground. . A heat pipe 4 is fixedly attached to the branch line 2 from approximately the middle to the lower part thereof, and the lower end part of the heat pipe 4 is formed in a spirally curved state. It is buried in a relatively high temperature heat collecting part 5 underground. Here, the heat pipe 4 has a structure in which a corrugated pipe is used as a container and substantially only a condensable fluid is sealed inside the container as a working fluid, and the above-ground portion is connected to the branch line 2 using heat insulating tape, aluminum tape, etc. Fixed. Although not shown in the drawings, the portion of the heat pipe 4 that is close to the ground surface has a heat insulating structure to prevent heat radiation from that portion.

。In the above device, during the snowy season, the temperature on the ground side is lower than the temperature of the underground heat collecting part 5, so the lower end of the heat pipe 4 located in the heat collecting part 5 becomes the heating part, and the branch line 2 Since the upper end side serves as a cooling section, the working fluid sealed inside evaporates at the lower end side, and the vapor flows to the upper end side and radiates heat, so that the heat pipe 4 absorbs geothermal heat. Bring it to the ground side and melt the snow around branch line 2.

らず、破断などの事故を防止することができる。In that case, in the above device, the part of the heat pipe 4 that is buried in the heat collecting part 5 and serves as the heating part is spiral-shaped, so the buried length of the heat pipe 4 per unit depth is In other words, even if the depth of the pipe 4 is shallow, the heat transfer area as a heating part is large, so there is sufficient heat input for snow melting, and therefore the area around the branch line 2 is Since the snow is melted and a hollow portion is formed, snow does not come into contact with the branch line 2, so no snow load is applied to the branch line 2, and accidents such as breakage can be prevented.

る。In addition, in the above embodiment, since the heat pipe 4 with a corrugated pipe as a container is used, the heat pipe 4 itself has flexibility, and therefore, it is difficult to form the heating part in a spiral shape or at the construction site. In addition, the surface area per unit length of the heat pipe 4 is increased, and heat input can be increased.

きる。As explained above, in this invention, among the heat pipes that melt snow by transporting geothermal heat to the surroundings of the branch line, a δ2
The part that collects geothermal heat is formed in a spiral shape.
The length of the heat pipe existing per unit depth becomes longer, and the area for heat collection, that is, the heat transfer area of the heating part, becomes wider. Therefore, in order to obtain the amount of heat required for snow melting, the heat pipe As a result, according to this invention, the depth of excavation can be made shallow, which reduces construction costs and shortens the construction period. can be made cheaper.
