위와 같은, 구성으로 이루어진 본 발명의 작동관계를 설명하면 다음과 같다.Referring to the operation of the present invention made of a configuration as described above are as follows.

우선, 상기 송전선(4)이 유동되지 않을 경우에는 상기 제1 및 제2링크부재(30,40)와 애자(3) 및 송전선(4)의 무게에 의해 상기 회전블록(20)은 도 3 내지 도 5에 도시한 바와 같이, 제1 및 제2링크부재(30,40)가 상하방향으로 길게 연장되도록 배치된다.First, when the transmission line 4 does not flow, the rotary block 20 is formed by the weight of the first and second link members 30 and 40, the insulator 3, and the transmission line 4. As shown in FIG. 5, the first and second link members 30 and 40 are arranged to extend in the vertical direction.

그리고, 상기 애자(3)에 연결된 송전선(4)이 상하방향으로 유동되면, 도 6a 내지 도 6b에 도시한 바와 같이, 제1 및 제2링크부재(30,40)가 각각 회동되면서 애자(3)가 송전선(4)에 추종되도록 하여, 애자(3)에 하중이나 진동이 전달되는 것을 방지하며, 이때, 상기 피스톤댐퍼기구(70)가 제2링크부재(40)의 회동에 따라 신축되면서 댐핑기능을 하여, 충격 발생을 최대한 억제되도록 한다.When the transmission line 4 connected to the insulator 3 flows in the vertical direction, as shown in FIGS. 6A to 6B, the first and second link members 30 and 40 are rotated, respectively, and the insulator 3 is rotated. ) To follow the power transmission line (4), to prevent the load or vibration is transmitted to the insulator (3), at this time, the piston damper mechanism 70 is expanded and damped as the second link member 40 rotates Function to minimize the occurrence of impact.

그리고, 상기 제1 및 제2링크부재(30,40)는 회전블록(20)에 힌지결합되며, 제2링크부재(40)는 제1링크부재(30)의 길이보다 짧게 구성되어, 애자(3)가 회전블록(20)의 회전중심축으로부터 이격되도록 고정되므로, 제1 및 제2링크부재(30,40)의 회동가능방향과 송전선(4)이 유동되는 방향이 서로 다를 경우, 회전블록(20)을 회전시키는 분력이 발생되어, 제1 및 제2링크부재(30,40)가 송전선(4)의 유동방향과 평행이 되도록 회전시키게 된다. The first and second link members 30 and 40 are hinged to the rotary block 20, and the second link member 40 is configured to be shorter than the length of the first link member 30. 3) is fixed so as to be spaced apart from the center of rotation of the rotation block 20, when the rotational direction of the first and second link members 30 and 40 and the direction in which the transmission line 4 flows are different, the rotation block The component force for rotating the 20 is generated so that the first and second link members 30 and 40 are rotated to be parallel to the flow direction of the power transmission line 4.

이를 좀 더 상세히 설명하면, 도 7a 내지 도 7b에 도시한 바와 같이, 상기 송전선(4)이 좌우방향으로 회동될 경우, 분력에 의해 제1 및 제2링크부재(30,40)가 측방향으로 연장되도록 회전블록(20)이 회전되며, 제1 및 제2링크부재(30,40)가 회동되므로써, 애자(3)에 하중과 진동이 전달되는 것을 방지한다.In more detail, as shown in FIGS. 7A to 7B, when the power transmission line 4 is rotated in the horizontal direction, the first and second link members 30 and 40 are laterally moved by the component force. The rotating block 20 is rotated to extend, and the first and second link members 30 and 40 are rotated to prevent the load and the vibration from being transmitted to the insulator 3.

이와 같이 구성된 본원발명에 따른 송전선로의 간섭방지용 완철은, 송전선(4)의 유동방향에 따라 제1 및 제2링크부재(30,40)가 가공선의 유동방향과 평행하게 배치되도록 회전블록(20)이 회전되고, 제1 및 제2링크부재(30,40)가 적절히 회동되어 애자(3)에 가해지는 하중과 진동을 흡수함으로써, 애자(3) 또는 애자(3)와 지지대(2)의 고정부위가 손상(반복된 하중에 의해 파손)되는 것을 미연에 방지할 수 있게 되는 것이다.The complete anti-interference of the transmission line according to the present invention configured as described above, the rotation block 20 so that the first and second link members 30 and 40 are arranged in parallel with the flow direction of the overhead line according to the flow direction of the transmission line 4. ) Is rotated, and the first and second link members 30 and 40 are rotated appropriately to absorb the load and vibration applied to the insulator 3, so that the insulator 3 or insulator 3 and the support 2 It is possible to prevent the fixed portion from being damaged (broken by repeated loads).

나아가, 상기 과정을 좀 더 구체적으로 설명하면, 도 8a 및 도 8b에 도시된 바와 같이, 측방향으로 부는 바람에 의해 송전선(4)이 회전축(21-1)을 중심으로 시계 또는 반 시계방향으로 축 회전하게 되면, 축 회전되는 회전축(21-1)에 의해 회전축(21-1)에 고정된 회전드럼(22)이 함께 회전되고, 이때 과도하게 시계 또는 반 시계방향으로 송전선(4)이 진자운동을 하게 되면, 이로 인하여 회전드럼(22)이 함께 회전되다가 회전드럼(22)의 중심방향으로 탄발되는 가압부재(12)의 선단부가 회전드럼(22)의 결합홈(22-1)으로 삽입되면서 회전되는 회전드럼(22)을 고정하게 된다.In more detail, the process will be described in more detail. As shown in FIGS. 8A and 8B, the transmission line 4 is rotated clockwise or counterclockwise about the rotating shaft 21-1 by the wind blowing in the lateral direction. When the shaft is rotated, the rotating drum 22 fixed to the rotating shaft 21-1 is rotated together by the rotating shaft 21-1, which rotates axially. At this time, the transmission line 4 penetrates excessively clockwise or counterclockwise. When the movement, due to this the rotary drum 22 is rotated together, the tip portion of the pressing member 12 is shot in the direction of the center of the rotary drum 22 is inserted into the coupling groove 22-1 of the rotary drum 22 While rotating the rotating drum 22 is fixed.

한편, 상기 가압부재(12)에 의해 고정된 회전드럼(22)은 추후에 작업자가 전신주(1)로 올라가 가압부재(12)에 의해 고정된 회전드럼(22)을 원상태로 회복되도 록 하여 준다.On the other hand, the rotating drum 22 fixed by the pressing member 12 allows the worker to climb to the telephone pole 1 later to restore the rotating drum 22 fixed by the pressing member 12 to its original state. .

이와 같이, 상기 회전드럼(22)을 가압부재(12)에 의해 고정되도록 함으로서, 측방향으로 부는 바람에 의해 송전선(4)이 꼬이는 것을 미연에 차단하여 송전선(4)이 손상되는 것을 미연에 차단할 수 있을 뿐만 아니라, 반복적인 진자운동에 의해 애자(3)에 무리를 주어 애자(3)가 손상되는 것을 원천적으로 차단할 수 있다.As described above, the rotating drum 22 is fixed by the pressing member 12, thereby preventing the transmission line 4 from being twisted by the wind blowing in the lateral direction, thereby preventing the transmission line 4 from being damaged. In addition, it is possible to fundamentally prevent the insulator 3 from being damaged by giving a strain to the insulator 3 by repetitive pendulum movement.
