Hereinafter, an embodiment in which the power supply pole is embodied will be described with reference to FIGS. 1 to 8.
As shown in FIGS. 1 and 2, the power supply pole Q consists of a single hollow cylinder in which a cable is routed, and has a main body 1 in which a lower end side is embedded and erected, and an upper end of the main body 1. It is provided with a device arrangement portion 2 in which devices such as switches and outlets are arranged on the side, and is composed of a lid member 6 that closes the upper end of the main body portion 1.

The main body 1 is a single hollow cylinder made of metal and forming a square cylinder, and a long groove 5 extending in the axial direction of the main body (cylindrical axial direction) is formed through a cable or a cable on the lower end side to be embedded. A protective tube can be introduced inside. Further, the upper end side is partially cut out, and the lid member 6 is attached so that the device arrangement portion 2 to which the exposed outlet and the intercom can be attached is arranged on the side portion of the main body portion.

Further, in the main body portion 1, in the side portion 1b on the side opposite to the side portion 1a where the equipment arrangement portion is located, a drain hole 3 (31, 32) for draining the water flowing into the inside of the main body portion to the outside is provided. ) Are provided at different positions in the axial direction of the main body. Further, on the side of each drain hole (31, 32), a display unit 4 suggesting the position of the ground line at the time of burying is provided. The display unit 4 is composed of an adhesive sheet on which the characters "GL" indicating the position of the adhesive sheet ground line are printed. On this adhesive sheet, a display "drainage hole" indicating that it is a drainage hole is printed on the display unit 4. The upper end of the colored portion where the “GL” of the display unit 4 is outlined is located at the same height as the lower end edge of the drain holes 3 (31, 32).

Further, a root skein 7 is attached between the long groove 5 on the lower end side and the drain hole 31 located below the drain holes 3. The root skein 7 prevents the main body 1 (power pole Q) from tilting, especially when it is buried in the soil. When burying the root skein 7 in concrete, there is little problem even if it is removed and buried.

The lid member 6 is made of synthetic resin, and as shown in FIG. 4, the device arrangement portion 2 having a flat surface and an opening, the lid portion 61 that closes the upper end of the main body portion 1, and the main body portion are wired. It is provided with a receiving port 62 for receiving a cable, and is screwed and integrated to the upper end portion of the main body portion 1.

Subsequently, the usage state of the power supply pole Q of the present embodiment will be described. As shown in FIG. 6, a power pole Q is erected in a hole in which a chestnut stone F is laid, a lower end side is buried in concrete and erected, and a cable protection pipe P buried in the soil passes through a long groove 5 and a lid. It is piped to the receiving port 62 of the member 6. The concrete C with the holes backfilled flows into the main body from the lower end of the main body 1 and the long groove 5, and is at the same position as the ground line G outside the main body.

When backfilled with soil, the fluidity is low, so the amount of water that enters the main body from the lower end of the main body 1 and the long groove 5 is small, and the water that has flowed into the main body soaks into the soil and is drained. Water does not collect in the main body, but when burying concrete as shown in Fig. 6, water collects in the main body, and the accumulated water evaporates and enters the equipment provided on the upper end side. A drain hole 3 is provided so as not to cause rust or malfunction due to dew condensation inside.

Further, by providing the drainage hole 3, even if the lower end side is blocked when burying concrete, it is possible to drain water from the drainage hole 3 to the outside, so that the lower end side is not blocked. There is no need. That is, by allowing the concrete C to flow into the main body 1 so as to be the same as the ground line G, the water in the main body can be drained from the drain hole 3. In this example, the root skein 7 is buried in the attached state, but the root skein is not always necessary.

Further, the drain holes 3 are provided at two locations (31 and 32) so that drainage can be performed at different positions in the axial direction of the main body, and as shown in FIGS. 7 and 8 (b), the ground line G is drained on the upper side. By increasing the buried amount (buried length) on the lower end side so as to correspond to the hole 32, drainage is possible even if the upward protrusion length H2 from the ground line G is lowered. Therefore, the height of the device arrangement portion can be changed to a desired height depending on the device to be attached and the surrounding environment. That is, as shown in FIG. 6, of the two drain holes (31, 32), the upward protrusion length from the land line G when the lower drain hole 31 and the ground line G are buried so as to be aligned with each other. The protrusion length H2 shown in FIG. 7 is smaller than that of H1.

Further, as shown in FIG. 3 (c), the axial length L2 of the long groove 5 on the lower end side of the drainage hole 3 (31, 32) is larger than the distance L1 from the lowermost end to the uppermost end where drainage is possible. It is formed large. As a result, the height of the power pole can be changed without changing the depth U of the cable protection pipe P buried in the soil (see FIGS. 6 and 7).

Further, since the drain holes 3 (31, 32) and the display unit 4 are provided on the opposite side of the equipment arranged in the equipment arrangement unit 2 in the main body unit 1, they are not conspicuous and are aesthetically pleasing.

The present invention is not limited to the above embodiment, and may be modified as follows.
-For example, although the device arrangement portion 2 is provided on the lid member 6 that is separate from the main body portion 1, it may be provided integrally with the main body portion 1 as shown in FIG.
-For example, the main body 1 is made of metal and has a square cylinder shape, but the material may be changed, and the main body portion 1 may be not limited to the square cylinder shape but may have a cylindrical shape.

-For example, the long groove 5 forming the cable introduction opening does not have to be formed longer than the distance L1 from the lowermost end to the uppermost end of the drainage holes that can be drained at different heights, and is not a long groove but a plurality of long grooves. A cable introduction opening may be formed by a through hole.

-For example, although a plurality of drain holes 3 (31, 32) are provided apart in the axial direction of the main body, they may be formed in a groove shape extending in the axial direction as shown in FIG. According to this example, the device arranging portion 2 can be arranged at an arbitrary height as long as the drain hole 3 faces the ground surface.

-For example, the drain hole 3 is provided on a side portion 1b different from the equipment arrangement portion 2, but may be provided on the same side 1a or on a side portion not opposite to the equipment arrangement portion 2. Further, not only one side portion but also a plurality of side portions may be provided individually or straddling each other.

-For example, the display unit 4 is provided with a plurality of adhesive sheets according to the number of drain holes 3, but a plurality of ground lines may be displayed by one adhesive sheet, and the display unit 4 is not limited to the adhesive sheet. It may be displayed by engraving or engraving.
