The anti-sag member 110 is installed symmetrically on both sides of the circular ring body 10 and the circular ring body 10 interposed between the plurality of overhead power transmission lines (C) to generate a tension change in the overhead power transmission line (C). It is configured to include a variable spacing sphere 20 for correcting this by its own elastic force.

At this time, the circular ring body 10 is a component for guiding the operation of the interval variable sphere (20). That is, the circular ring body 10 is a means for guiding the movement of the overhead power transmission line (C) when a change in tension occurs in the overhead power transmission line (C). A pair of opening holes 13 are respectively provided on both sides with reference to (11), and guide holes 15 opened up and down are formed in upper and lower portions of each opening hole 13 .

The variable spacing sphere 20 is configured to include a leaf spring 21 , an overhead power transmission line binding piece 23 , and a connecting ring body 27 .

At this time, the leaf spring 21 is a component that provides an elastic force for correcting the tension of the overhead power transmission line (C), and hinge holes 22 are provided at both ends, and it is preferable that the overall shape is made in an arc shape.

The overhead power transmission line binding piece 23 is made up of two sets and one pair so as to wrap the overhead power transmission line C, and is hinge-rotatably connected by hinge pins 24 at both ends of each leaf spring 21, and guide holes 15 ), a guide pin 26 inserted into the guide hole 15 to slide along the protrusion is formed.

In addition, a hinge hole 25 is provided on one side of the overhead power transmission wire binding piece 23 to communicate with the hinge hole 22 and into which the hinge pin 24 is inserted.

Here, the nut N is fastened to the end of the guide pin 26 inserted into the guide hole 15 to prevent the overhead power transmission wire binding piece 23 from being separated from the guide hole 15 .

In addition, the connecting ring body 27 is a component for connecting the overhead power transmission line binding piece 23 consisting of two sets of one pair, and is bound to both ends of the overhead power transmission line binding piece 23 by a bolt fastening method.

At this time, the connection ring body 27 is provided with a cutout 28 so as to be connected to the overhead power transmission line binding piece 23 by spreading it. Accordingly, the connecting ring body 27 is tightly bound to the outer surface of the overhead power transmission wire binding piece 23 made of two sets of one pair by its own elastic force.

The anti-sag member 110 is a pair of arc-shaped plate springs 21 that spreads the overhead power transmission line C in both directions by its own elastic force when deflection occurs due to a change in tension of the overhead power transmission line. By making it possible to efficiently control the tension of the overhead power transmission line (C), the sagging phenomenon of the overhead power transmission line (C) can be prevented in advance. The operation state of this anti-sag member 110 is illustrated in FIG. 4 .

4 is a view for explaining the operating state of the anti-sag member of the overhead power transmission line according to an embodiment of the present invention. If you do:

First, the circular ring body 110 is positioned between the overhead power transmission lines C that are parallel to each other, and an arc-shaped plate spring 21 end is inserted into each opening hole 13 . After that, it is connected to the overhead power transmission line (C) using the overhead power transmission line binding piece 23 consisting of two sets and one pair, and the overhead power transmission line binding piece 23 is attached to the end of the leaf spring 21 with a hinge pin ( 24) to enable hinge rotation.

At this time, the hinge pin 24 is inserted and connected to the hinge hole 22 and the hinge hole 25 .

In addition, if the connecting ring body 27 is placed at both ends of the overhead power transmission line binding piece 23 composed of two sets and one pair, and then the connecting ring body 27 is placed, the connecting ring body 27 is processed by its own elastic force. The outer surface of the power transmission line binding piece 23 is wrapped, and then, when the connecting ring body 27 is rotated, the connecting ring body 27 is fastened to the overhead power transmission line binding piece 23 by a bolt fastening method.

In addition, the guide pin 26 is inserted into the guide hole 15 and the nut N is fastened to the end thereof.

The deflection preventing member 110 of the overhead power transmission line installed in this way has an arc shape as shown in the dotted line in FIG.

Thereafter, when the overhead power transmission line C is in a taut state using a tensioner (not shown), the leaf spring 21 is in a flat state as shown by the solid line in FIG. 4 .

In addition, when the tension of the overhead power transmission line (C) is loosened after a predetermined period of time has elapsed after the installation of the overhead power transmission line (C), the leaf spring 21 forms an arc again as shown by the dotted line in FIG. 4, and the overhead transmission line (C) is pushed in both directions so that the overhead power transmission line (C) can maintain the taut tension.

At this time, the variable spacing sphere 20 moves along the guide hole 15 when the leaf spring 21 returns to the arc shape by its own elastic force, and induces the overhead power transmission line C to be opened in both directions. .

Accordingly, the anti-sag member 110 allows the arc-shaped plate spring 21 to spread the overhead power transmission line in both directions by its own elastic force to efficiently adjust the tension of the overhead power transmission line. In addition, in the installation process, the overhead power transmission line binding piece 23 consisting of two sets and one pair can tightly wrap the upper and lower parts of the overhead power transmission line, so that the sagging preventing member 110 of the overhead power transmission line is related to the change in tension of the overhead power transmission line. It is firmly installed and fixed without any need to maintain a safe installation state.

For example, by preventing the accumulation of contaminants such as foreign substances or corrosion in advance in the opening hole 13 , the guide hole 15 , and the hinge hole 25 , the normal operation of the sagging preventing member 110 is prevented. It is possible to prevent the interfering elements in advance, thereby preventing the deterioration of the tension control performance of the overhead power transmission line of the sagging member 110 .

By implementing the upper/lower caps 120 and 130 in a hemispherical shape, respectively, it is possible to minimize the accumulation of contaminants on the outer surfaces of the upper/lower caps 120 and 130 .

In addition, at least one LED lamp 121 on the inner surface of the upper/lower caps 120 and 130, and determining whether to drive the LED lamp 121 based on a change in tension generated in the plurality of overhead power transmission lines (C) It may further include a switch (not shown). At this time, the switch (not shown) is preferably installed at a predetermined position in contact with the overhead power transmission wire binding piece 23 moving by tension or restoration of the leaf spring 21 . For example, the switch (not shown) is installed in a predetermined position of the guide hole 15 or the opening hole 13, and drives the LED lamp 121 by the movement of the overhead power transmission line binding piece 23 (that is, luminescence) can be determined.

For this reason, the present invention is characterized in that when the change in tension generated in the overhead power transmission line (C) reaches a dangerous level, it can be checked and dealt with from a remote location.

In addition, the present invention is provided with an LED lamp emitting light of at least one color, and by displaying the degree of risk according to the change in tension by the color of the LED lamp, the degree of risk can be displayed step by step, thereby, It is also possible to determine this from a remote location and to respond appropriately according to the level of risk.

In this case, the upper/lower caps 120 and 130 may be implemented as a translucent material to diffuse the light of the LED lamp 121 .

On the other hand, when the LED lamp 121 is emitted at all times regardless of the change in tension, the device for preventing sagging of the overhead power transmission line 100 according to the present invention has a feature that can serve as an aviation obstacle indicator. At this time, by varying the color or brightness of the LED lamp 121 according to the surrounding illuminance, it is possible to improve the discrimination power. To this end, the apparatus 100 for preventing sagging of an overhead power transmission line according to the present invention may further include an illuminance sensor (not shown).

The self-power generation unit 140 is a means for generating self-power by natural wind, a pinwheel rotating by natural wind, a power generation unit (not shown) that generates self-power based on the rotation of the pinwheel, and It may be configured to include a battery unit 152 for storing the self-power. The self-power generated at this time may be used as power for driving the LED lamp 121 .

The pinwheel is preferably installed at a position where it can be greatly affected by the wind, and as illustrated in the drawing, it may be installed on the upper end of the upper cap 120 .

In addition, as illustrated in the drawings, the battery unit 152 may be installed inside a center of gravity bar 150 to be described later to act as a weight.
