The rod 220 is opened upward to form a sliding hole 221 along the longitudinal direction and the fixing grooves 222 are formed on the upper surface of the sliding hole 221 at regular intervals.

The insulator 230 includes a cable fixing end 231 formed on the upper portion thereof for fixing the cable 20, an extension rod 232 extending downward from the lower portion thereof, A rod 233 disposed between the rod 232 and extending over the rod 220 in the vicinity of the sliding hole 221 and a fixing plate 233 provided at the lower end of the rod 232, As shown in FIG.

Further, the clamping plate 233 is bolted to the rod 220 to fix its position.

Next, the operation and effect of the power distribution tower having the cable line variable function according to the temporary example of the present invention through the above-described configuration will be described.

Referring to FIG. 1, a case of constructing an electricity distribution tower according to the present invention will be described as an example.

First, the lower end of the power distribution tower body 100 is embedded in the paper surface 10 and fixed. A plurality of rotary supports 200 are installed on the upper portion of the power distribution tower body 100. In the case shown in FIG. 1, the rotating supports 200 are arranged in two stages.

A spacer 300 having a predetermined length is positioned between the rotatable supporters 200. Therefore, the rotary supports 200 may be spaced apart from each other by a certain distance.

At this time, the rotary plate 210 of the rotary support 200 and the spacers 300 are gear-connected to each other. An elastic member 320 that externally senses the center shaft 110 is positioned between the spacer 300 and the rotary support 200. Accordingly, a certain amount of elastic force exists between the rotary supports 200 and the spacers 300.

Rods 220 protruding at a predetermined length are installed on both sides of the rotary plate 210. After determining the wiring direction of the cable 20 connected to the insulator 230 located on the top of the rod 220, the direction of the rod 220 is determined. The placement direction of the rod 220 is determined according to the wiring direction of the cable 20.

The wiring direction of the cable 20 is achieved by rotating the rotating plate 210. Therefore, after the rotation plate 210 is rotated at a predetermined angle, the rotation plate 210 is fixed to the spacer 300. Fixing the spacer 300 and the rotation plate 210 is determined by aligning the position fixing holes 212 formed in the spacer 300 and the rotation plate 210. Then, the first fixing member 213, such as a bolt, is inserted into the position fixing holes 212, and the position is fixed.

Therefore, the rotational position of the rotary support 200 is varied and positioned, and accordingly, the wiring direction of the cable 20 is determined to be variable.

If the rods 220 are parallel to each other, a bird may form a nest. In order to prevent this, the rod 220 may be rotated up and down to fix its position .

Referring to FIG. 3, the second rotating portion 224 of the rod 220 hinged to the first rotating portion 214 of the rotating plate 210 is rotated.

That is, when the rod 220 is rotated downward, the first fixing holes 214b formed in the pair of hinge supporting ends 214c and the second fixing holes 214b formed in the second rotating portion 224 of the rod 220 2 fixing holes 224b can be varied and positioned. After the positions of the first and second fixing holes 214b and 224b match the desired positions, the second fixing member 223 is inserted into the first and second fixing holes 214b and 224b, As shown in Fig.

Also, the case where the rod 220 is rotated upward is also performed in the same manner as described above.

At this time, the rod 220 is rotated about the rotation axis C inserted in the first and second rotation holes 214a and 224a.

In addition, when the power distribution tower is constructed as described above, a plurality of insulators 230 may be arranged on the upper portion of the rod 220. FIG. That is, by varying the position of the insulator 230, the distance between the cables 20 can be varied.

The case where any one of the insulators 230 is varied at the upper portion of the rod 220 will be described.

Referring to FIG. 4, first, the hooking plate 233 or the insulator 230 is lifted upward. The extension rod 232 connecting between the hooking plate 233 and the fixed end 234 is positioned to slide in the sliding hole 221 of the rod 220 and is smaller than the width of the sliding hole 221 So that it is lifted above the rod 220.

That is, the fixed end 234 may be separated from the fixing groove 222 formed on the upper surface of the sliding hole 221. After the removed fixed end 234 is moved to the position of another fixing groove 222 formed at another position, the fixed end 234 is inserted into the fixing groove 222 and positioned.

The hooking plate 233 extends over the upper surface of the sliding hole 221. At this time, bolts are fastened to the clamping plate 233 and the rod 220 to fix the position thereof. The description of the bolt fastening method will be omitted because it is conventionally adopted by the same technique using a bolt and a nut.

On the other hand, after the distribution tower is constructed by varying the distribution direction of the cable 20 such as the distribution line, the distribution direction of the cable 20 may be reset and changed.

When the first fixing member 213 fixing the rotational position of the rotary plate 210 is detached from the position fixing hole 212 as described above, the spacing member 300 and the rotary plates 210 are separated from each other, The elastic members 320 are spaced apart from each other by a predetermined distance. That is, they are mutually open. After rotating the rotary support 200 to a variable position thereafter, the first fixing member 213 is used to fix the position thereof.

Since the surfaces of the spacer 300 and the rotary plate 210 which are in contact with each other are connected by the gear teeth G, even if the first fixing member 213 is partially broken, It may not be easy to change.

As described above, according to the present invention, when a power distribution tower is constructed, a plurality of rotary support bodies, in which insulators are installed and supported by cables, are rotated in the body of the power distribution tower, There is an effect that can be made.

In addition, since the rods provided on the turntable can be rotated in an upward / downward direction and fixed to be inclined, it is possible to prevent nests such as birds from forming nests, thereby preventing a fire and a power failure .

In addition, when the power distribution tower is installed, the position of a plurality of insulators fixed to the rods of the rotary support can be easily changed, and the line width between the cables can be easily set.

In addition, when one of the plurality of insulators fastened to the rods of the rotary support is broken and replaced when the power distribution tower is installed, no separate material is consumed and can be easily replaced, There is also an effect of reducing the cost of the system.

Further, since the operator inserts a bolt hole into the rods of the rotary support located at a high altitude, the bolt hole is drilled and the bolt is tightened by sliding the bolt hole to a predetermined position without varying the position of the insulators. It is possible to prevent human accidents in advance.
