Overhead wires are routed through ground structures such as electric poles. In this case, overhead wires placed on both sides of the ground structure are electrically connected to each other through jumper wires. If the jumper wire is installed in a downward direction, algae nests will not form. On the other hand, if the jumper wire is constructed upward, accidents that occur close to the female tie of the jumper wire can be prevented. Therefore, the jumper wire can be installed by rotating it according to the surrounding environment of the installation location.

If the jumper line rotates due to wind pressure, vibration, or natural passage of time, it is difficult to make a clear judgment because the reference point changes depending on the viewing angle even if a patrolling employee observes it from under a utility pole.

Figure 1 shows a location where the jumper wire fixing device 100 (shown in Figure 2) according to an embodiment of the present invention is used. A jumper wire fixing device 100 may be installed at the dotted line circle in FIG. 1 .

As shown in Figure 1, a jumper wire (P) is stretched downward with the electric pole (P) in between to electrically connect the power lines to each other. A horizontal support (H) is fixedly installed on the electric pole (P) and connected to the jumper wire (P) by an insulator (I). However, since the jumper wire (P) is stretched, the jumper wire (P) may become twisted or tangled due to wind, etc. In this case, since it has a negative effect on the power line, it is necessary to fix the jumper wire (P) so that it does not rotate. In particular, rotation of the jumper wire (P) is also caused by rotation of the insulator (I) and the connection part 50 coaxially engaged with it, so when fixing the connection part 50, rotation of the jumper wire (P) can be prevented. there is.

As shown in FIG. 1, the connection part 50 includes a pair of plate-shaped brackets 501, an insulator connection part 503, a fixing pin 505, and a connection rod 507. In addition, the connection part 50 may further include other parts.

A pair of plate-shaped brackets 501 are connected to the electric pole (P). That is, the pair of plate-shaped brackets 501 are fixedly installed on the horizontal support (H) fixed to the electric pole (P) and connected to the electric pole (P) through the horizontal support (H). A pair of plate-shaped brackets 501 are inclined and connected to each other. That is, the pair of plate-shaped brackets 501 are respectively attached to the upper and lower parts of the horizontal support (H), and are inclined so that the separation distance gradually narrows and meets each other on the right side of the horizontal support (H). An opening 501a is formed when a pair of plate-shaped brackets 501 meet each other. One end of the connecting rod 507 is caught and fixed in the opening 501a.

The insulator connection portion 503 is connected to the insulator (I). The insulator connection portion 503 includes a pair of connection cantilevers 5031 and a support portion 5033. A pair of connection cantilevers 5031 are spaced apart from each other. An opening 5031a is formed in each pair of connection cantilevers 5031. A pair of connecting cantilevers 5031 are connected to each other through a support portion 5033.

The fixing pin 505 extends in the y-axis direction across the pair of connecting cantilevers 5031. A fixing pin 505 is inserted into each opening 5031a. An opening (not shown, hereinafter the same) through which the fixing pin 505 passes is formed at the other end of the connecting rod 507. Since the other end of the connecting rod 507 is located between a pair of connecting cantilevers 5031, the fixing pin 505 is inserted into the opening 5031a and the opening of the connecting rod 507 to connect the insulator connecting portion 503 and connected.

As shown by the dotted line in FIG. 1, the jumper wire fixing device according to an embodiment of the present invention prevents the connection portion 50 from being twisted and prevents the jumper wire (J) from rotating. The structure of this jumper wire fixing device will be described below with reference to FIGS. 2 and 3.

Figure 2 schematically shows a jumper wire fixing device 100 according to an embodiment of the present invention. The structure of the jumper wire fixing device 100 in FIG. 2 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the structure of the jumper wire fixing device 100 can be modified differently.

As shown in FIG. 2, the jumper wire fixing device 100 includes a length-variable fixing unit 10 and a rotatable fixing unit 20. In addition, the jumper wire fixing device 100 may further include other components. The jumper wire fixing device 100 is installed on the connection portion 50 (shown in FIG. 1) to suppress rotation of the jumper wire J (shown in FIG. 1).

The length-variable fixing unit 10 extends long along the y-axis direction. The length variable fixing unit 10 is connected to one end of the rotatable fixing unit 20. The rotatable fixing unit 20 extends in the x-axis direction intersecting the y-axis direction.

The rotatable fixing unit 20 is formed of multiple joints and can rotate around axes in multiple directions. For example, the rotatable fixation unit 20 may rotate about the x-axis or y-axis. Additionally, the rotatable fixing unit 20 may rotate about another direction crossing the x-axis direction and the y-axis direction, for example, the z-axis direction. The rotatable fixing unit 20 includes a hook portion 2015 formed at its other end. Therefore, since the rotatable fixing unit 20 can rotate in multiple directions, the jumper wire fixing device 100 can be fixed by freely moving the hook portion 2015 regardless of the location.

Meanwhile, the length variable fixing unit 10 includes a rod part 101, a screw fixing part 103, a fastener part 105, a fixed support part 107, a screw part 109, and a ring part 111. do. In addition, the length variable fixing unit 10 may further include other components.

The rod portion 101 extends long along the y-axis direction. The cross section of the rod portion 101 is formed in a polygonal shape. That is, the cross section of the rod portion 101 is formed at an angle. By forming the cross section of the rod portion 101 to be polygonal rather than circular, it is possible to prevent the pair of guide plates 1053 from separating. That is, the cross-section of the rod unit 101 is formed into a polygon so that it interferes with the pair of guide plates 1053, thereby minimizing the separation of the pair of guide plates 1053.

The fixed support portion 107 is located at one end of the rod portion 101. The screw fixing part 103 is located at the other end of the rod part 101. A screw hole 103a extending along the y-axis direction is formed in the screw fixing portion 103.

The screw portion 109 has an outer surface formed in a screw shape. The screw portion 109 extends long along the y-axis direction. The screw portion 109 is spaced apart in parallel with the rod portion 101 and rotates and translates along the rod portion 101. The screw portion 109 may move along the y-axis direction through the screw hole 103a. That is, when the screw part 109 is rotated clockwise, the fastener part 105 gradually approaches the fixed support part 107. Conversely, when the screw portion 109 is rotated counterclockwise, the fastener portion 105 gradually moves away from the fixed support portion 107.

The ring portion 111 is formed at one end of the screw portion 109. The ring portion 111 is located further outside the rod portion 101, that is, in the +y axis direction. Therefore, the jumper wire fixing device 100 can be fixed by inserting the securing hook into the ring portion 111 and rotating the screw portion 109. That is, since the high-voltage power line cannot be accessed during indirect live wire work, the jumper wire fixing device 100 can be fixed near the jumper wire using the hook 111.

The fastener portion 105 is formed at the other end of the screw portion 109. The fastener portion 105 moves along the rod portion 101. As a result, the separation distance between the fastener portion 105 and the fixed support portion 107 can be adjusted. That is, after inserting the plate-type bracket between the fastener part 105 and the fixed support part 107, the jumper wire fixing device 100 can be fixed to the plate-type bracket by narrowing the distance between the fastener part 105 and the fixed support part 107. You can.

The fastener portion 105 includes a fastener body 1051, a pair of guide plates 1053, and a bracket cover portion 1055. In addition, the fastener unit 105 may further include other components.

The fastener body 1051 is connected to a pair of guide plates 1053. The fastener body 1051 is seated on the rod portion 101. Since the fastener body 1051 is supported by a pair of guide plates 1053 and is seated on the rod portion 101, the fastener body 1051 can move stably along the y-axis direction.

A pair of guide plates 1053 are positioned to be spaced apart from each other along the z-axis direction. A pair of guide plates 1053 are located on both sides of the rod unit 101. As the screw portion 109 rotates, the pair of guide plates 1053 moves along the y-axis direction.

The bracket cover portion 1055 is connected to the other end of the fastener body 1051 and the screw portion 109. The bracket cover portion 1055 forms a bracket insertion space S that is concave toward the fixed support portion 107. Therefore, the plate-type bracket can be stably fixed by inserting it into the bracket insertion space (S). That is, the plate-shaped bracket is firmly fixed on both sides of the rod portion 101 by the fixed support portion 107 and the fastener portion 105, respectively.

The fixed support portion 107 includes a flat surface 1071 and a support piece 1073. In addition, the fixed support 107 may further include other components. The flat surface 1071 is formed parallel to the zx plane. The flat surface 1071 faces the bracket insertion space S along the y-axis direction. The support piece 1073 supports the flat surface 1071. The cross-sectional area of the support piece 1073 gradually increases as it approaches the rod portion 101. The fixed support portion 107 is formed in the shape of a right triangle. Therefore, the plate-shaped bracket can be stably and firmly fixed between the fixed support portion 107 and the fastener portion 105.

Meanwhile, the rotatable fixing unit 20 includes a universal joint portion 201, a fixing piece portion 203, a rotation inhibiting portion 205, a rotating portion 209, a polygonal column portion 211, a grip portion 213, and a hook portion. Includes (215). In addition, the rotatable fixing unit 20 may further include other components.

The universal joint portion 201 is formed on the side of the rod portion 101. The universal joint portion 201 is located between the fixed support portion 107 and the fastener portion 105.

Hereinafter, the structure of the rotary fixing unit 20 included in the jumper wire fixing device 100 of FIG. 2 will be described in more detail with reference to FIG. 3.

FIG. 3 schematically shows an exploded structure of the rotary fixing unit 20 included in the jumper wire fixing device 100 of FIG. 2. The disassembled structure of the rotary fixing unit 20 in FIG. 3 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the disassembled structure of the rotary fixing unit 20 can be modified differently.

As shown in FIG. 3, the rotatable fixing unit 20 includes a universal joint portion 201, a fixing piece portion 203, a rotation inhibiting portion 205, a screw 207, a rotating portion 209, and a polygonal column portion ( 211), a grip portion 213, and a hook portion 215. In addition, the rotatable fixing unit 20 may further include other components.

The fixing piece portion 203 is connected to the universal joint portion 201 along the x-axis direction. The rotating part 209 is connected to the fixed piece part 203. The rotating part 209 includes a pair of arms 2091 and a lower part 2093 spaced apart from each other. A pair of arms 2091 is connected to the lower part 2093 and the polygonal pillar portion 211, and a screw 207 is located between them. The lower part 2093 is coupled to the fixing piece 203 by the screw 207 and rotates.

The rotating unit 209 may rotate about the x-axis direction. The polygonal pillar portion 211 is located on the rotating portion 209 and is connected to the rotating portion 209. The cross section of the polygonal pillar portion 211 is formed in a polygonal shape. For example, the cross-section of the polygonal pillar portion 211 may be square. As a result, the rotation inhibiting portion 205 can be hung on both sides of the polygonal column portion 211 to inhibit rotation of the rotatable fixing unit 20. That is, before fixing the jumper wire fixing device, the rotary fixing unit 20 can rotate around multiple axes to secure the free position of the hook portion 215, etc. However, after the jumper wire fixing device is positioned, further rotation is not necessary for fixation, so the rotation of the rotatable fixing unit 20 can be suppressed using the rotation inhibiting portion 205 and the polygonal column portion 211. .

The rotation inhibiting portion 205 is attached to the side of the fixing piece portion 203. The rotation inhibiting portion 205 includes a first plate portion 2051, a second plate portion 2053, and a third plate portion 2055. The first plate portion 2051 extends in a direction intersecting the x-axis direction. The second plate portion 2053 is connected to the first plate portion 2051. The second plate portion 2053 extends in a direction intersecting the first plate portion 2051. The third plate portion 2055 is connected to the second plate portion 2053. The third plate portion 2055 extends in a direction intersecting the second plate portion 2053. A fixing groove 2055a is formed in the third plate portion 2055. The fixing groove 2055a includes a pair of inner surfaces 2055a1. A pair of inner surfaces 2055a1 face parallel to the side surface of the polygonal pillar portion 211. Therefore, when the polygonal pillar portion 211 is inserted into the fixing groove 2055a, it cannot rotate and is thus firmly fixed to the fixing groove 2055a. As a result, additional rotation of the rotatable fixing unit 20 can be suppressed.

Meanwhile, the rotation inhibiting portion 205 further includes a pair of side portions 2057 and a rotation axis 2061. A pair of side portions 2057 are installed on both sides of the connection portion of the first plate portion 2051 and the second plate portion 2053, respectively. The rotation axis 2061 is rotationally fixed to the pair of side parts 2057 and crosses the pair of side parts 2057. As a result, the first plate portion 2051 and the second plate portion 2053 are connected to the rotation axis 2061 and rotate about the rotation axis 2061.

Returning to Figure 2, the rotation inhibiting portion 205 further includes an elastic member 2058 (shown in Figure 2). The elastic member 2058 connects one or more side portions of the pair of side portions 2057 and the first plate portion 2051. As a result, even if the rotation inhibiting portion 205 is pulled and released from the polygonal column portion 211 by the elastic force of the elastic member, the rotation inhibiting portion 205 returns to the polygonal column portion 211 and remains in the polygonal column portion 211. is inserted into Therefore, the rotation inhibition state of the rotation type fixing unit 20 by the rotation inhibition unit 205 is firmly maintained.

The grip portion 213 protrudes in the direction in which the hook portion 215 extends, that is, in the -y-axis direction, which is opposite to the +y-axis direction. In addition, the rotatable fixing unit 20 is formed in a direction that intersects the direction in which it extends, and is formed in a ring shape.

The shape of this grip part 213 is useful when the hook part 215 is inserted at a specific location to fix the jumper wire fixing device, and then release the fixing state when necessary. That is, since it is difficult to remove the hook portion 215 inserted inside a specific location, the grip portion 213 located in the opposite direction of the hook portion 215 is grasped and lifted. Therefore, the fixed state of the jumper wire fixing device can be easily released.

Figure 4 schematically shows a flowchart of a method for attaching and detaching a jumper wire fixing device according to an embodiment of the present invention. The method of attaching and detaching the jumper wire fixing device in FIG. 4 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the method of attaching and detaching the jumper wire fixing device can be modified differently.

As shown in Figure 4, the method of attaching and detaching the jumper wire fixing device includes the steps of providing a jumper wire fixing device (S10), attaching the hook to the securing hook included in the clamp stick (S20), and providing the clamp stick. A step of arranging in parallel in two directions (S30), a step of inserting the screw part located between the ring part and the screw fixing part among the screw parts, and the ring part into the clamp stick (S40), inserting the hook between the support part and the connecting rod. Step (S50), positioning one of a pair of plate brackets between the fixed support portion and the fastener portion in the width direction (S60), rotating the screw portion forward to bring the plate bracket into close contact with the fixed support portion and the fastener portion. It includes a step of fixing (S70) and a step of removing the clamp stick (S80). In addition, the method of attaching and detaching the jumper wire fixing device may further include other steps.

Figures 5 to 8 schematically show each step of the method of attaching and detaching the jumper wire fixing device described above. Therefore, hereinafter, the method of attaching and detaching the jumper wire fixing device will be described in detail through FIGS. 5 to 8, focusing on FIG. 4.

First, in step S10, a jumper wire fixing device is provided. That is, the jumper wire fixing device 100 of FIG. 2 can be used.

In step S20, the hook portion 111 of the jumper wire fixing device 100 is attached to the securing hook 510 included in the clamp stick 500. (shown in FIG. 5) As a result, preparations are made for work by connecting the jumper wire fixing device 100 to the clamp stick 500 using an indirect live wire method. Meanwhile, a hollow space 500a is formed inside the clamp stick 500. Since the hollow space 500a is formed to be long along the direction in which the clamp stick 500 extends, the jumper wire fixing device 100 can be manipulated as desired by partially inserting the length-variable fixing unit 10 to fix the jumper wire. Work can be easy.

Returning again to FIG. 4, in step S30, the clamp stick 500 is arranged parallel to the second direction, that is, the direction in which the length variable fixing unit 10 is extended. As a result, preparations can be completed to partially insert the length-variable fixing unit 10 into the hollow space 500a.

In step S40, the screw part 109 (shown in FIG. 5) and the ring part 111 (shown in FIG. 5) located between the ring part and the screw fixing part among the screw parts are inserted into the clamp stick 500. (shown in FIG. 6), that is, part of the length variable fixing unit 10 is inserted into the hollow space 500a within the clamp stick 500.

In step S50, the hook portion 215 is inserted between the support portion 5033 and the connecting rod 507. (shown in FIG. 6) As a result, the rotary fixing unit 20 can be firmly fixed to the connection portion 50.

Returning to Figure 4, in step S60, one of the pair of plate-shaped brackets 501 is positioned between the fixed support portion 107 and the fastener portion 105 in the width direction. (Showed in FIG. 7) FIG. 7 shows a state in which the jumper wire fixing device 100 is fixed to the upper bracket of a pair of plate-shaped brackets 501. The rotation of the polygonal pillar portion 211 is suppressed by the rotation inhibiting portion 205. Therefore, the jumper wire fixing device 100 is once stably fixed on the connecting rod 507 by inserting the hook portion 2015.

In step S70 of FIG. 4, the screw portion 109 is rotated forward to secure the plate-shaped bracket 501 in close contact between the fixed support portion 107 and the fastener portion 105. (shown in FIG. 7) That is, since the ring portion 111 is engaged with the clamp stick 500, the clamp stick 500 is manipulated to rotate the ring portion 111 to rotate the screw portion 109 forward. As a result, as the fastener portion 105 moves forward, the separation distance between the fixed support portion 107 and the fastener portion 105 is reduced, thereby allowing the plate-shaped bracket 501 to be fixed.

Finally, in step S80, the clamp stick is removed. (shown in FIG. 8) As a result, the length variable fixing unit 10 included in the jumper wire fixing device 100 is fixed to the plate bracket 501 in the x-axis direction, and the rotatable fixing unit 20 is attached to the hook portion. It is fixed on the connecting rod 507 along the y-axis direction by (215). That is, since the variable fixing unit 10 and the rotatable fixing unit 20 cross each other and are fixed to the connection portion 50, the jumper wire J can be fixed more firmly. To this end, the curvature of the portion of the connection portion 50 that is fastened to the hook portion 215 may be greater than or equal to the curvature of the hook portion 215 . More preferably, the curvature of the portion of the connecting portion 50 that is fastened to the hook portion 215 may be substantially the same as the curvature of the hook portion 215.

The jumper wire fixing device 100 is fixed to the connection portion 50 in the form of a crossbar. Therefore, problems such as the jumper wire (J) being twisted or falling off due to rotation of the connection portion 50, etc. can be easily solved.

FIG. 9 schematically shows another attachment method of the jumper wire fixing device 100 of FIG. 1. The attached state of the jumper wire fixing device 100 in FIG. 9 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the attachment state of the jumper wire fixing device 100 can be modified differently. In addition, the attached state of the jumper wire fixing device 100 in FIG. 9 is a state in which the jumper wire fixing device 100 in FIG. 8 is rotated by 90 degrees, so the same reference numerals are used for the same parts and detailed description thereof is omitted.

As shown in FIG. 9, when the fixing pin 505 is located in the x-axis direction, that is, toward the side, the hook portion 215 can be inserted in the horizontal direction. This is different in the case where the hook portion 215 is inserted in the vertical direction in FIG. 8. Since the rotatable fixing unit 20 can rotate 360 degrees about its longitudinal axis, this action is possible. That is, the jumper wire fixing device 100 according to an embodiment of the present invention can be applied to connections in various states.

Figure 10 schematically shows a flowchart of another method of attaching and detaching a jumper wire fixing device according to an embodiment of the present invention. The method of attaching and detaching the jumper wire fixing device in FIG. 10 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the method of attaching and detaching the jumper wire fixing device can be modified differently.

As shown in Figure 10, the method of attaching and detaching the jumper wire fixing device, and more specifically, the detachment method, includes the step of hanging the securing hook on the grip part and pulling the hook out between the support part and the connecting rod (S90), and reversing the screw part. It includes rotating the fastener part to move it away from the plate bracket (S100), and separating the fixed support part and the fastener part from the plate bracket. In addition, the method of attaching and detaching the jumper wire fixing device may further include other steps.

First, in step S90, the grasping hook is hung on the gripping part and the hook is pulled out between the support part and the connecting rod. As a result, once the rotatable fixing unit can be separated from the connection part.

Next, in step S100, the screw unit is reversely rotated to move the fastener unit away from the plate bracket. In other words, the fastener moves toward the clamp stick.

Finally, in step S110, the fixed support part and the fastener part are separated from the plate bracket. In other words, the fastening part is made to have a greater separation distance from the fixed support part by using the screw part. As a result, the fixed support portion and the fastener portion can be separated from the plate bracket. Therefore, the jumper wire fixing device can be removed from the connection part.

Although the present invention has been described according to the foregoing description, those skilled in the art will easily understand that various modifications and variations are possible without departing from the concept and scope of the claims described below.
