Description

Technology Field

[0001] The present invention relates to a space-type lightweight rack for low-voltage aerial branching, and more specifically, to a space-type lightweight rack for low-voltage aerial branching capable of preventing sagging of low-voltage aerial branching wires and introducing stable low voltage. Background Technology

[0002] Generally, racks are installed on utility poles installed on the ground to support low-voltage and neutral wires wired in 2, 3, or 4-wire configurations, and by connecting the low-voltage and neutral wires to the racks, sagging and shaking caused by their own weight are prevented. However, existing racks that support wires in only one direction and can only support wires of a set thickness cause problems such as prolonged installation and maintenance time, which increases the likelihood of safety accidents, including casualties.

[0003] In particular, there are currently no overhead line racks dedicated to low-voltage aerial branching. The current situation involves installing vertical overhead branching racks in the middle of low-voltage lines using existing 2-wire racks (single-phase) and 4-wire racks (three-phase). When installing low-voltage aerial branching using existing low-voltage overhead line racks dedicated to utility poles, there is a problem where the low-voltage lines and service entrance wires sag due to the weight of the steel structure.

[0004] Korean Patent Publication KR 10-2013-0039565 A (2013.04.22) The problem to be solved

[0005] Therefore, the objective of the present invention is to provide a space-type lightweight rack for low-voltage aerial branching that prevents complaints regarding sagging of low-voltage wires and improves the aesthetics of low-voltage facilities by ensuring that the low-voltage wires are fixed and maintained in a state that prevents left and right slippage. means of solving the problem

[0006] A space-type lightweight rack for a low-voltage aerial branch according to the present invention for achieving the above objective comprises: a rack body part formed as a pair to clamp a low-voltage wire; and a body coupling part that fixes and connects the pair of rack body parts to maintain the clamped state of the low-voltage wire of the pair of rack body parts while the pair of rack body parts clamp the low-voltage wire. By connecting the pair of rack body parts with the body coupling part, the low-voltage wire can be clamped, and as a result, the low-voltage wire can be fixed and maintained in a state that prevents left and right slippage, thereby preventing complaints regarding sagging of the low-voltage wire and improving the aesthetics of the low-voltage facility.

[0007] Here, it is desirable that the pair of rack body parts further include a rotatable coupling part that allows one side of the pair of rack body parts to be rotatably connected, so that the user's convenience can be improved because the pair of rack body parts are not separated and are not individual.

[0008] Furthermore, it is desirable that the pair of rack main bodies further include a clamping recess formed by being recessed from the surface of the pair of rack main bodies to receive and clamp the low-voltage wire, so that stable clamping can be achieved by receiving and clamping the low-voltage wire in the clamping recess.

[0009] Here, the clamping recess is formed according to the number of low-voltage wires, so it is desirable to be able to clamp while accommodating the low-voltage wires even when there are two or three low-voltage wires.

[0010] In addition, it is desirable to further include a pair of anti-slip members that prevent the rack main body from sliding relative to the low-voltage wire when clamping while receiving the low-voltage wire by being positioned inside the clamping recess and clamping it, so that the low-voltage wire can be clamped and fixed in a state that prevents left and right sliding.

[0011] Here, it is preferable to further include a branch support member formed on either of the pair of rack main bodies to connect and support the branch wire, so as to prevent sagging of the low-voltage wire while connecting and supporting the branch wire.

[0012] And the branch support member is preferably further comprising a pair of support extension members extending from two regions at a predetermined distance from one of the pair of rack main body members; and a branch wire support member connected and coupled to the pair of support extension members, so that the branch wire can be stably maintained in a coupled state.

[0013] Here, it is preferable that the branch support member further includes an insulating connection member formed to allow the branch wire to be connected in an insulated manner, which is rotatably supported while accommodating the branch wire support member, thereby enabling the connection of branch wires connected in multiple directions while being insulated.

[0014] And, the above main body coupling part is preferably formed by penetrating or recessing a pair of the above rack main bodies; and a male coupling part inserted and coupled to the above female coupling part, so that a pair of rack main bodies can be coupled to firmly clamp a low-voltage wire.

[0015] Here, the female coupling part has female screw threads formed on the inside, and the male coupling part has a bolt shape and male screw threads formed on the outside. It is desirable that an operating groove is formed to prevent the user from gripping and slipping, so that operation can be easily performed even when the user grips and rotates it through the operating groove. Effects of the invention

[0016] According to the present invention, a pair of rack main body parts can be joined by a main body coupling part to clamp a low-voltage wire, and as a result, the low-voltage wire can be fixed and maintained in a state where it is prevented from sliding left or right, thereby preventing complaints regarding sagging of the low-voltage wire and improving the aesthetics of the low-voltage facility.

[0017] In addition, by utilizing space-type lightweight racks for low-voltage aerial branching of low-voltage single-phase supply lines in fishing villages, it is possible to reduce investment costs by eliminating the installation of one utility pole.

[0018] In addition, since the pair of rack main bodies are separated and not individual, user convenience can be improved, and since the low-voltage wire is received and clamped in the clamping recess, stable clamping can be achieved.

[0019] In addition, even when the low-voltage wire is a 2-wire or 3-wire type, it can be clamped while accommodating the low-voltage wire, and the low-voltage wire can be clamped and maintained in a fixed state that prevents left and right slippage.

[0020] In addition, it can prevent sagging of low-voltage wires, support branch wires by combining them, and maintain stability in the combined state.

[0021] In addition, branch wires that are insulated and connected in multiple directions can be connected, and a pair of rack main bodies can be combined to firmly clamp low-voltage wires. Furthermore, the device has the effect of allowing easy operation even when a user grasps and rotates it via the operating groove. Brief explanation of the drawing

[0029] The second rack body (12) has a long rod shape, and one side is rotatably connected to the first rack body (11) by a rotational coupling part (30).

[0030] The main body coupling part (20) fixes and connects a pair of rack main body parts (10) so as to maintain the clamping state of the low-voltage wires of the pair of rack main body parts (10) while the pair of rack main body parts (10) are clamping the low-voltage wires. The main body coupling part (20) includes a female coupling part (21) and a male coupling part (22).

[0031] The female coupling portion (21) may be formed by penetrating or recessing a pair of rack body portions (10). The female coupling portion (21) may have female screw threads formed on the inside.

[0033] The control groove (221) can be held by the user and prevented from slipping.

[0034] The rotational coupling part (30) can rotatably connect one side of a pair of rack body parts (10).

[0035] A clamping recess (40) can be formed by being recessed from the surface of a pair of rack body parts (10) to accommodate and clamp low-voltage wires. The clamping recess (40) can be formed according to the number of low-voltage wires.

[0036] The anti-slip member (50) is positioned inside the clamping recess (40) so that when clamping while accommodating the low-voltage wire, the pair of rack main body parts (10) can be prevented from sliding against the low-voltage wire.

[0037] A branch support member (60) is formed on one of a pair of rack main body members (10) so that a branch wire can be connected and supported. The branch support member (60) includes a first support extension member (61), a second support extension member (62), a branch wire support member (63), and an insulation connection member (64).

[0043] Fig. 2 (a) Construction shape of a long-span low-voltage utility pole reflecting site conditions. A total of 3 utility poles are required, including the installation of new poles in the middle of the long span.

[0044] Fig. 2 (b) When constructing a space-type lightweight rack for low-pressure aerial branching, the construction of intermediate poles can be omitted, so only one pole is required on each side. Here, when utilizing a rack developed for a single-phase supply line, it is possible to maintain a span of 100m or more per span.

[0052] The anti-slip member can be made of a flexible material such as urethane or rubber, and it is preferable that it be made of a material capable of insulation.

[0053] Since the branch wire support must be connected and maintained in a state where it is combined with the first support extension and the second support extension, it may have a rod shape made of metal. The branch wire support may be made of an insulating material, and it is preferable that it be made of a material that has high strength so that shape deformation does not occur even after the branch wire is connected.

[0054] Due to the above-described space-type lightweight rack (1) for low-voltage aerial branching, a pair of rack body parts can be connected to the body part coupling part to clamp the low-voltage wire, and as a result, the low-voltage wire can be fixed and maintained in a state that prevents left and right slippage, thereby preventing complaints regarding sagging of the low-voltage wire and improving the aesthetics of the low-voltage equipment.

[0055] In addition, by utilizing space-type lightweight racks for low-voltage aerial branching of low-voltage single-phase supply lines in fishing villages, it is possible to reduce investment costs by eliminating one utility pole installation.

[0056] In addition, since the pair of rack main bodies are separated and not individual, user convenience can be improved, and stable clamping can be achieved by accommodating the low-voltage wire in the clamping recess.

[0058] In addition, it can prevent sagging of low-voltage wires, support branch wires by combining them, and maintain stability in the combined state.

[0059] In addition, branch wires connected in multiple directions while being insulated can be connected, and a pair of rack main bodies can be combined to firmly clamp low-voltage wires, and operation can be easily performed even when a user holds and rotates it through the operating groove.
