Description

Underground distribution line arrangement device for improved safety of wire connection

[0001] The present invention relates to an underground distribution line arrangement device for improving safety of wire connection.

[0002] High-voltage electricity transmitted from power plants or substations is transformed into a certain voltage and then distributed to consumption areas. This distribution can be done through overhead lines or underground lines.

[0003] Distribution management is done through wiring adjustments of overhead or underground cables. In large cities where wiring adjustments are frequent, the underground cable wiring method is widely used because it improves space utilization and facilitates wiring adjustment and management.

[0004] Wiring adjustments of underground cables can be made through connection control between underground cables, between underground cables and distribution lines, and between underground cables and distribution boxes, and these connections are made through connecting devices (or connectors).

[0005] The above connecting device (or connector) is installed on a cantilever-shaped tray (hanger). When installed in this manner, if a strong vibration such as an earthquake is applied from the outside, the tray (hanger) shakes, which eventually causes damage to the fixed part, making maintenance inevitable.

[0006] In addition, conventional trays (hangers) could not freely adjust the area where underground cables were installed, so the trays had to be installed at close intervals to prevent sagging of underground cables, which had the fundamental problem of relatively increasing construction costs.

[0007] The purpose of the present invention is to provide an underground distribution line arrangement device for wire connection with improved safety, which can facilitate the installation of underground distribution lines, thereby maximizing the convenience of the work, facilitate the easy and simple withdrawal of underground distribution lines accommodated in an installation platform, and prevent sagging of underground distribution lines by firmly fixing the underground distribution lines.

[0008] The present invention to achieve the above purpose,

[0009] A support arm composed of a fixed member installed on the wall of a power utility, a pipe body that supports an underground distribution line that extends horizontally from the fixed member and is placed on the upper surface, a pedestal connection part that protrudes from the side of both ends of the pipe body and is formed to face each other with respect to the pipe body, and a supporter connection part that protrudes from the side of both ends of the pipe body to be positioned lower than the table connection part and is formed to face each other with respect to the pipe body.

[0010] A distribution line mounting unit comprising a body having a 'C' shape with an interior that is open toward the direction of installation and the wall of the power tunnel so that underground distribution lines to be installed can be removably accommodated, and is integrally formed at the end of the pipe, wherein the interior is formed such that the upper surface and the side surface are perpendicular to each other, and the inner lower surface is formed to slope upward toward the wall of the power tunnel, and the inner upper surface, lower surface, and side surface are provided with guide portions sunken with a constant width and depth, and an installation stand comprising idlers that are installed on the inner upper surface, side surface, and lower surface of the body respectively so as to face each other with respect to the guide portion and reduce friction when the underground distribution lines move;

[0011] A pedestal that is interconnected with a pedestal connection part and a pin so that it can be folded or unfolded, and can be used to place underground distribution cables,

[0012] A wire clamp installed on the upper surface of the pedestal to pressurize and fix the underground distribution wires that are introduced inside,

[0013] A wire fixing member consisting of a supporter that is interconnected to enable folding and unfolding via a supporter connection part and pins and supports and supports the lower part of the unfolded stand;

[0014] A motor accommodated in the body,

[0015] A lead screw that rotates by a motor,

[0016] A push unit consisting of a push nut block that is accommodated in the body so that it can be guided by a guide section and pushes the underground distribution line inserted into the installation stand to the support arm while reciprocating along the length of the lead screw;

[0017] An operation switch installed in a distribution line support unit that outputs an operation signal;

[0018] It is characterized by including a control unit that receives an operation signal from an operation switch and controls the operation of a motor so that a push nut block moves back and forth along a guide unit.

[0019] The present invention can maximize the convenience of work by facilitating the installation of underground distribution lines, and can easily and simply pull out underground distribution lines accommodated in an installation platform, making work convenient, and can firmly fix underground distribution lines, thereby preventing sagging of underground distribution lines.

[0038]

[0039] Referring to FIGS. 1 to 5, the underground distribution line arrangement device for improving safety for wire connection according to the present invention is composed of a distribution line support unit (100), a wire fixing member (200), a push unit (300), an operation switch (400), and a control unit (500). Accordingly, the underground distribution line (L) can be easily installed, thereby maximizing the convenience of the work. The underground distribution line (L) accommodated in the installation member (120) can be easily and conveniently pulled out, thereby making the work convenient. The underground distribution line (L) can be firmly fixed, thereby minimizing safety accidents caused by sagging of the underground distribution line (L).

[0040]

[0041] Referring to FIGS. 1 to 4, the power distribution line support unit (100) is composed of a support arm (110) and an installation stand (120). In the present embodiment, it is installed (fixed) in a cantilever shape on the wall surface of a power tunnel (T) via a fixing means (anchor bolt) and is used for the purpose of installing an underground power distribution line (L) or placing an installed underground power distribution line (L).

[0042] The above support rock (110) is composed of a fixed piece (111), a pipe body (112), a pedestal connection part (113), and a supporter connection part (114) and serves to support the installed underground distribution line (L).

[0043] The above fixed member (111) is a square plate, and in the present embodiment, it is fixed against the wall of the power hole (T) using a fixing means (anchor bolt).

[0044] The above-mentioned pipe body (112) is a square pipe having a space provided inside, and one end is integrally formed with a fixed piece (111), and is installed horizontally in a cantilever shape on the wall surface of a power pipe (T) via the fixed piece (111), and the other end is integrally formed with a body (121) that constitutes a mounting base (120).

[0045] For example, the inside of the above-mentioned body (112) is connected to the inside of the body (121), and the motor (310) and lead screw (320) of the push unit (300) are accommodated inside the body (112) and the body (121).

[0046] The above-mentioned pedestal connecting portion (113) protrudes parallel to the sides of both ends of the pipe body (112) and is placed between the fixed piece (111) and the installation base (120), with the upper surface positioned on the same plane as the upper surface of the pipe body (112), and is formed to face each other with respect to the pipe body (112), and the pin (P) is fitted in a horizontal direction.

[0047] The above supporter connecting portion (114) protrudes from the side surfaces of both ends of the pipe body (112) so as to be positioned lower than the pedestal connecting portion (113), but is positioned between the supporter connecting portions (114), and is formed to face each other with respect to the pipe body (112), and the pin (P) is fitted in a vertical direction.

[0048] The above-mentioned laying platform (120) is composed of a body (121) and an idler (122), and in the case of the present embodiment, it is integrally formed at the end (opposite the fixed piece) of the pipe body (112) and is used for laying underground distribution lines (L).

[0049] The above body (121) has a 'C' shape with the interior opened toward the direction of installation and the wall of the power pipe (T) so that the underground distribution line (L) to be installed can be inserted and received in a removably manner, and the interior of the body (121) has a structure in which it is mutually connected with the interior of the pipe (112) (see FIGS. 3 and 4).

[0050] The interior of this body (121) has upper and side surfaces that are perpendicular to each other, and the lower surface is formed to slope upward from one side (the lower side of the front) toward the wall of the power tunnel (T). By forming the lower surface to slope in this way, the underground distribution line (L) introduced inside slides and is placed as close as possible to the inner side surface, so that the left-right movement of the underground distribution line (L) can be suppressed as much as possible during the installation process, allowing the work to proceed stably.

[0051] In addition, a guide part (121a: see Fig. 4) that is sunken (opened) with a certain width and depth is integrally provided on the inner upper surface, side surface, and lower surface of the body (121), and a push nut block (330) of the push unit (300) is installed in this guide part (121a) so that it can move back and forth.

[0052] The above idler (122) is a type of roller, and in the present embodiment, it is installed on the inner upper surface and side and the inclined lower surface of the body (121) so as to be able to idle, and rotates in place when moving in the direction of laying the underground distribution line (L) to reduce friction.

[0053]

[0054] Referring to FIGS. 1 to 4, the wire fixing member (200) is composed of a supporter (210), a wire clamp (220), and a supporter (230). In the present embodiment, it is installed so as to be foldable or unfoldable on a support arm (110) and serves to pressurize and fix an underground distribution line (L) that is installed thereon.

[0055]

[0056] The above-mentioned support (210) is a plate having a predetermined width and thickness, and in the case of the present embodiment, it is interconnected to be foldable or unfoldable via a table connection part (113) and a pin (P) to support an underground distribution line (L).

[0057] The above-mentioned wire clamp (220) is a ring-shaped member whose outer surface is cut to a predetermined width. In the present embodiment, it is installed on the upper surface of the support (210) and serves to pressurize and fix an underground distribution line (L) that is inserted and detachably inserted through the cut inner side.

[0058] The above supporter (230) is interconnected to be foldable or unfoldable via the supporter connection part (114) and the pin (P) and serves to support and support the lower part of the unfolded stand (210).

[0059] For example, when the supporter (230) is rotated upward around the pin (P), the supporter (210) is placed horizontally, and when the supporter (230) is rotated counterclockwise around the pin (P), the upper surface is brought into contact with the lower surface of the supporter (210), thereby supporting the supporter (210) without it folding.

[0060] As described above, since the area around the support rock (110) is expanded by the pedestal (210), the area where the underground distribution line (L) is installed can be expanded, so that the sagging of the underground distribution line (L) can be minimized. Furthermore, since the wire clamp (220) pressurizes and fixes the installed underground distribution line (L), the sagging of the underground distribution line (L) can be more reliably prevented.

[0061]

[0062] Referring to FIG. 1 and FIG. 3 to FIG. 5, the push unit (300) is composed of a motor (310), a lead screw (320), and a push nut block (330). In the present embodiment, it is installed in the distribution line support unit (100) and, when the installation is completed, it serves to pull out the underground distribution line (L) from the installation stand (120).

[0063] The above motor (310) is a conventional servo motor, and in the case of this embodiment, it is installed in the support arm (110) and its operation is controlled by the control unit (500) to rotate the lead screw (320) in the forward or reverse direction.

[0064] The above lead screw (320) is a member having threads formed on the outer surface, and in the case of the present embodiment, one end is connected to the motor (310), and the other end is rotatably installed on the installation stand (120) via a bearing (see FIG. 4).

[0065] The above-mentioned push nut block (330) is a rectangular prism-shaped member, and in the case of the present embodiment, is arranged to be reciprocally movable on the guide portion (121a) of the installation stand (120). This push nut block (330) is coupled to the lead screw (320) and moves reciprocally in a straight line along the longitudinal direction of the lead screw (320) by the rotation of the lead screw (320). In this way, in the process of the push nut block (330) moving toward the support arm (110), the underground distribution line (L) installed in the installation stand (120) is pushed to the support arm (110) by the push nut block (330) and pulled outward.

[0066] For example, the motor (310) is operated by the control unit (500) to rotate clockwise at a set rotation speed, and when the set rotation speed is reached, it rotates counterclockwise at a set rotation speed and then stops, and accordingly, the push nut block (330) performs a linear reciprocating motion once in the forward and backward direction along the longitudinal direction of the lead screw (320).

[0067]

[0068] Referring to FIGS. 1 to 5, the operation switch (400) is installed on the front of the installation stand (120) of the distribution line support unit (100) and serves to output an operation signal.

[0069] For example, when a worker presses the operation switch (400), an operation signal is output and input to the control unit (500).

[0070]

[0071] Referring to FIG. 5, the control unit (500) receives an operation signal from the operation switch (400) and controls the operation of the motor (310).

[0072] For example, when an operation signal is input from the operation switch (400), the control unit (500) controls the operation of the motor (310). The motor (310) is operated by the control unit (500) to rotate clockwise by a set number of rotations, and when the set number of rotations is reached, it rotates counterclockwise by the set number of rotations and then stops. Accordingly, the push nut block (330) performs one linear reciprocating motion in the forward and backward direction along the longitudinal direction of the lead screw (320).

[0073]

[0074] Figures 6 and 7 are drawings for explaining the operation and effect of the underground distribution line arrangement device for improving safety for wire connection according to the present invention, and the following description is made with reference to these drawings.

[0075] The worker just needs to unfold the folded wire fixing bracket (200). First, by rotating the supporter (210) of the wire fixing bracket (200) upwards around the pin (P), the supporter (210) is placed horizontally, and by rotating the supporter (230) around the pin (P), the upper surface is brought into contact with the lower surface of the supporter (210), thereby supporting the supporter (210) from folding.

[0076] When the installation work of the wire fixing member (200) is completed as described above, the worker inserts the underground distribution line (L) to be installed into the inside of the body (121) of the installation member (120) and places it on the idler (122).

[0077] Next, when the worker grabs and pulls the tip of the inserted underground distribution line (L), the underground distribution line (L) moves, and at this time, the idler (122) rolls in place to reduce friction with the underground distribution line (L).

[0078] In addition, since the lower surface inside the body (121) is formed to be inclined, the underground distribution line (L) slides along the inclined idler (122) and is positioned as close as possible to the idler (122) positioned on the inner side, and accordingly, the movement of the underground distribution line (L) to the left and right can be suppressed as much as possible during the installation process, so that the installation work can be carried out stably.

[0079] And when the worker presses the operation switch (400) while the underground distribution line (L) is laid to the planned section, an operation signal is output and input to the control unit (500), and the control unit (500) receives the operation signal from the operation switch (400) and controls the operation of the motor (310).

[0080] The above motor (310) is controlled by the control unit (500) to rotate clockwise at a set rotational speed, and during this process, the lead screw (320) also rotates, and due to the rotation of the lead screw (320), the push nut block (330) moves toward the wall of the power conduit (T), and during this process, the underground distribution line (L) accommodated in the body (121) is pulled out from the body (121) and placed in the pipe (112).

[0081] And when the motor (310) rotates clockwise and reaches the set rotation speed, the control unit (500) controls the operation so that the motor (310) rotates counterclockwise, and during this process, the lead screw (320) also rotates, and due to the rotation of the lead screw (320), the push nut block (330) moves and returns to its initial state.

[0082] Meanwhile, when the underground distribution line (L) arranged in the above-mentioned pipe (112) is inserted into the wire clamp (220), the underground distribution line (L) is not only pressurized and fixed by the wire clamp (220), but also the area supporting the underground distribution line (L) by the support (210) is expanded, thereby preventing the sagging of the installed underground distribution line (L). Due to this effect, there is no need to install the underground distribution line arrangement device according to the present invention in a dense manner, so there is an advantage in that construction costs can be drastically reduced.

[0083] In addition, there is an advantage in that the underground distribution line (L) accommodated in the installation platform (120) can be easily and conveniently pulled out through the above-mentioned push unit (300), making work more convenient.

[0084]

[0085] Although the present invention has been described in detail only with respect to the described specific embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made within the technical scope of the present invention, and it will be apparent that such modifications and variations fall within the scope of the appended claims.
