欠点があつた。 In winter, ice and snow may accumulate on power transmission line suspension supports, so-called steel towers.In such conditions, steel towers have a large surface area that is exposed to the wind due to ice and snow, resulting in increased wind pressure resistance and Due to the increased load, etc., there is not only a risk of collapse but also a risk of short circuit. For example, ice and snow may adhere to the insulators of aerial termination connections on steel towers, i.e. connections made of insulators, insulating materials, etc., which are installed to connect power transmission lines suspended by the tower and underground cables. In such cases, due to the conductivity of ice and snow, a short circuit may occur between the transmission line and the tower through the ice and snow. Countermeasures against short circuits include enlarging the shape of the insulator to increase the distance between the power transmission line attached to the insulator and the steel tower, or changing the shape of the insulator to a shape that makes it difficult for snow to adhere to it. . However, in the case of the former of these measures, the size of the insulator must be determined within the strength limits of the steel tower, and especially in areas with heavy snowfall, a large amount of snow adheres to the large insulator, resulting in a large load on the steel tower. There are limits to the size of insulators for reasons such as: Furthermore, even in the latter case, it is difficult to reliably prevent the adhesion of ice and snow, and therefore it is not possible to reliably prevent short circuits. Therefore, in order to eliminate this inconvenience,
Conventionally, devices have been considered to melt the ice and snow that has accumulated on the insulator, and one example is a snow melting device that transports thermal energy possessed by underground water or geothermal heat, which does not require energy costs, to the insulator via a heat pipe. can. In other words, this type of snow melting device generally has one end of the heat pipe installed near the bottom surface of the insulator, and hot water obtained as a result of underground water pumped up by digging a well or water supplied to a geothermal well, to the other end of the heat pipe. It is true. However, snow melting equipment with this type of configuration requires equipment such as pumps to pump up groundwater or supply water to geothermal wells, leading to problems such as increased equipment costs, increased maintenance costs, and high running costs. be. Therefore, a snow melting device may be considered in which the other end of the heat pipe is inserted into the well or the geothermal well.
However, wells or geothermal wells that are dug to obtain sufficient groundwater or geothermal heat for snow melting are underground.
The snow melting device requires a fairly long heat pipe because the depth may be more than 10 meters and the height of the insulator on the steel tower may be more than 10 meters. However, since the exterior of conventional heat pipes is usually composed of a straight pipe with high rigidity, it is not only nearly impossible to transport a fairly long heat pipe, but even if it were not possible to transport it, it would be difficult to transport it. Even so, there were problems such as the extremely difficult task of inserting a heat pipe, which is made up of a fairly long straight pipe, 10 meters underground without bending it. Therefore, conventional snow melting devices have such problems and have the disadvantage that they cannot be easily installed.

とされている。 Embodiments of this invention will be described below with reference to the accompanying drawings. Figures 1 to 3 show an embodiment of this invention, in which an air terminal connection part 3 is connected to a support base 4 on a suspension part 2 that projects almost horizontally from a power transmission line suspension support, so-called a steel tower 1. It is protruded through. The air terminal connection portion 3 is composed of an insulator 5 forming an exterior body, an insulating material, and the like. Further, as shown in FIG. 1, the power transmission line 6 led from another tower 1 is held back at the aerial termination connection 3, and the held power transmission line 6 is passed through the insulator 5 and is connected to the ground. Connected to the middle cable. Further, a heat dissipation plate 7 is provided at the base end of the insulator 5 with a support base 4 interposed therebetween.
As shown in FIG. 2, the heat dissipation plate 7 has a shape with a semicircular notch so as not to hit the lower protrusion of the air terminal connection part 3, and is formed in a pair. A plurality of cylindrical spaces are formed in a direction perpendicular to the end face having a semicircular notch, and the cylindrical spaces penetrate only to the end face opposite to the end face. Further, a heat sink plate heat pipe 8 is inserted into the cylindrical space, and the heat sink plate 7 containing the heat sink plate heat pipe 8 is closed by a header 9. Further, the upper end of a heat pipe 10 for transporting geothermal heat is connected to each header 9, and the heat pipe 10 branches off at a predetermined position from the upper end and becomes one line below the branching point. The lower end is inserted into the geothermal well 11. As shown in FIG. 3, the heat pipe 10 has a structure in which a corrugated pipe, for example, a stainless steel corrugated pipe with a diameter of 50 mm, is used in a part as the exterior body 12, and a flexible wick 13 is used in the exterior body 12. It has a structure in which a working fluid is sealed in an exterior body 12, and a heat insulating material 14 is coated on the outer peripheral surface of at least a portion of the exterior body 12 located on the ground.

を変形させながら接続を容易に行なえる。 Therefore, the snow melting device constructed as described above melts snow at the aerial terminal connection as follows. That is, the heat pipe 10 transports heat if there is a temperature difference between one end and the other end, so when it snows, the heat pipe 10 connected to the header 9
Since one end is at a low temperature, a temperature difference occurs between the other end inserted into the geothermal well 11 and the one end.
The heat pipe 10 transports geothermal heat to the heat sink 7 via the header 9. The heat transferred to the heat sink 7 is radiated and warms the insulator 5 from the base end. As a result, the ice and snow that have accumulated on the insulator 5 are removed from the heat pipe 1.
It can be solved by geothermal energy through 0. By the way, when installing the snow melting device configured as described above, one end of the heat pipe 10 is connected to the geothermal well 11.
When inserting the heat pipe 10 into the geothermal well 11, the heat pipe 10 is bent at the flexible portion of the heat pipe 10. Furthermore, when leading the heat pipe 10 from the geothermal well 11 to the header 9 on the steel tower 1, the heat pipe 10 can be easily fixed by bending the heat pipe 10 and attaching it to the side of the steel tower 1 as described above. Even when connecting the heat pipe 10 to the header 9, the heat pipe 10
Connections can be easily made while deforming the

できる等の効果がある。 As is clear from the above explanation, since this invention uses a heat pipe with a flexible structure in a snow melting device that uses groundwater or geothermal heat, the number of wells and geothermal wells that are dug to utilize groundwater or geothermal heat is considerable. Even in deep areas, a fairly long heat pipe can be deformed and transported, and a long heat pipe can be easily inserted into a well or geothermal well, making it easy to install the snow melting device of this invention. In addition, when a flexible corrugated pipe is used as the exterior body of the heat pipe,
Since a heat pipe using a corrugated pipe has a larger surface area than a heat pipe using a straight pipe as an exterior body that has the same outer diameter as the corrugated pipe, the electric heating area is larger. Therefore, the amount of heat transported per unit time by the heat pipe increases. As a result, the efficiency of melting the ice and snow that has accumulated on the air terminal connection is improved. Furthermore, the larger the temperature difference between the heat input part and the heat radiation part of the heat pipe, the more
Since it has the property of increasing the amount of heat transported, it can be expected to have an even greater snow melting effect under low temperature weather conditions such as during snowfall.
