Description

Technology Field

[0001] The present invention relates to a D-type rack structure, and more specifically, to a D-type rack structure having a support band that prevents rotation of the D-type rack structure due to the tension of a wire and allows for easy reinstallation even if rotation occurs. Background Technology

[0002] Generally, the purpose of the D-type rack for single-line installation (hereinafter referred to as the 'D-type rack structure') is to prevent safety accidents involving people and animals by maintaining an appropriate separation distance when the low-voltage line or neutral line in an overhead power distribution line is insufficient from a structure or is in close proximity to streetlights, road signs, etc.

[0003] In other words, when a ground fault occurs while the multi-grounded neutral wire of a 22.9kV-y extra-high voltage line is in contact with a street light or road sign, and the fault current is discharged to the ground through the neutral wire via the street light or road sign, there is a risk of electric shock due to the ground voltage, so the neutral wire must be kept separate from the ground using a D-type rack structure.

[0004] FIG. 1 briefly illustrates a conventional D-type rack structure. Referring to FIG. 1, the conventional D-type rack structure is composed of a conventional main body (4) for connecting and supporting wires, a bar-shaped conventional support part (3) integrally connected to the main body (4), and a conventional support band (2) connected to the end of the support part (3) to allow it to be fixed to a utility pole (1), etc.

[0005] At this time, tension is generated by the wire connected to the main body (4), and due to the generated tension, the D-shaped rack structure rotates, and as a result, the distance from the wire is reduced, which causes a problem.

[0006] In addition, when the D-type rack structure rotates, the D-type rack structure must be removed and reinstalled, which results in a power outage and makes the work difficult. Prior art literature

[0021] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0022] Terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms.

[0023] The above terms are used solely for the purpose of distinguishing one component from another.

[0024] Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the invention are omitted.

[0025] A D-type rack structure of one embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0026] FIG. 2 shows a plan view of a D-type rack structure according to the present invention.

[0027] As illustrated in FIG. 2, a D-shaped rack structure according to one embodiment of the present invention comprises a support band (10) fastened to one side of a utility pole (1), a main body (40) for connecting and supporting a wire, a bar-shaped support part (20) integrally connected to the main body (40), and a connecting part (30) integrally connected to the support band (10), characterized in that the support band (10) and the support part (20) are connected by the connecting part (30).

[0028] The main body (40) has the same configuration as the conventional main body (4) and corresponds to the prior art, so a detailed description thereof will be omitted.

[0029] The support band (10) may be formed in a circular shape for effective connection with the utility pole (1), and teeth (12) may be formed in the center direction on the inner side of the support band (10).

[0030] At this time, one side of the tooth (12) is formed perpendicular to the support band (10).

[0031] More specifically, one side of the tooth (12) is formed perpendicular to the tangential direction of the support band (10).

[0032] That is, when the support band (10) rotates due to the tension of the wire, a tooth (12) may be formed in the center direction on the inner side of the support band (10) to improve the resistance against the direction of rotation of the support band (10), and one side of the tooth (12) is formed perpendicular to the support band (10) to suppress rotation.

[0033] More specifically, when the support band (10) rotates clockwise, the left side of the tooth (12) is formed perpendicular to the support band (10), and when the support band (10) rotates counterclockwise, the right side of the tooth (12) can be formed perpendicular to the support band (10).

[0034] At this time, the point where one side of the tooth (12) is formed perpendicular to the support band (10) can be determined according to the position of the wire connected to the main body (40).

[0035] FIG. 3 shows a front view of a D-type rack structure according to the present invention.

[0036] FIG. 4 shows a detailed view of a connecting part, which is a component of a D-type rack structure according to the present invention.

[0037] As shown in FIGS. 3 and 4, the connecting portion (30) has a fixing hole (32) and a variable hole (34) formed through the connecting portion (30), and the fixing hole (32) and the variable hole (34) are formed spaced apart, and the variable hole (34) is formed closer to the support band (10) side than the fixing hole (32).

[0038] Additionally, there may be multiple variable holes (34), and FIG. 4 shows three variable holes (34), namely a first variable hole (34a), a second variable hole (34b), and a third variable hole (34c).

[0039] At this time, a plurality of variable holes (34) can be formed along the circumference of a circle centered on a fixed hole (32).

[0040] That is, the first variable hole (34a), the second variable hole (34b), and the third variable hole (34c) can be formed along the circumference of a circle centered on the fixed hole (32).

[0041] As illustrated in FIGS. 3 and 4, a first hole (22) and a second hole (24) are formed in the support member (20) that penetrate the support member (20), and the first hole (22) and the second hole (24) are spaced apart and formed along the longitudinal direction of the support member (20), and the second hole (24) is formed closer to the support band (10) side than the first hole (22).

[0042] The support band (10) and the support member (20) are connected by the connecting member (30), and more specifically, the first connecting member (36) connects the connecting member (30) and the support member (20) through the fixing hole (32) and the first hole (22), and the second connecting member (38) connects the connecting member (30) and the support member (20) through the variable hole (34) and the second hole (24), so that the support band (10) and the support member (20) can finally be connected.

[0043] Accordingly, it is preferable that the fixed hole (32) and the first hole (22) are formed to correspond to each other, and that the variable hole (34) and the second hole (24) are also formed to correspond to each other.

[0044] The first connecting member (36) and the second connecting member (38) are fastening or coupling devices, and may be bolts and nuts, etc. Since this corresponds to the prior art, a detailed description is omitted.

[0045] FIG. 5 shows an embodiment of a D-type rack structure according to the present invention.

[0046] FIG. 5(a) shows the initial state of the D-type rack structure according to the present invention. That is, it is a state in which no tension is generated by the wire connected to the main body (40).

[0047] FIG. 5(b) shows a case where the D-shaped rack structure according to the present invention rotates clockwise due to tension from the wire connected to the main body (40), and FIG. 5(c) shows a case where the D-shaped rack structure according to the present invention rotates counterclockwise due to tension from the wire connected to the main body (40).

[0048] When a conventional D-type rack structure is initially installed, no rotational force is generated because it can withstand the tension caused by the wires; however, as time passes, it can no longer withstand the tension, causing the conventional D-type rack structure to rotate, and as a result, the distance from the wires is reduced.

[0049] Accordingly, the D-type rack structure according to the present invention has the effect of maintaining a distance from the wire by changing the connection angle with the connecting part (30) of the support part (20) when rotational force is generated, as shown in FIG. 5 (b) and (c).

[0050] FIG. 5(b) shows a case where the support member (20), which is loaded by a wire connected to the main body (40), rotates clockwise, and is characterized by adjusting the angle of the support member (20) in the opposite direction to the direction of rotation to prevent a reduction in the distance from the wire.

[0051] More specifically, the first connecting member (36) connecting the fixed hole (32) and the first hole (22) is fixed, and the second connecting member (38) connecting the second variable hole (34b) and the second hole (24) is unfastened, and the second connecting member (38) is fastened so that it can connect the third variable hole (34c) and the second hole (24), thereby allowing the angle of connection with the connecting part (30) of the support part (20) to be modified.

[0052] Figure 5 (c) shows a case where the support member (20), which is loaded by a wire connected to the main body (40), rotates counterclockwise, and is characterized by adjusting the angle of the support member (20) in the opposite direction to the direction of rotation to prevent a reduction in the distance from the wire.

[0053] More specifically, the first connecting member (36) connecting the fixed hole (32) and the first hole (22) is fixed, and the second connecting member (38) connecting the second variable hole (34b) and the second hole (24) is unfastened, and the second connecting member (38) is fastened so that it can connect the first variable hole (34a) and the second hole (24), thereby allowing the angle of connection with the connecting part (30) of the support part (20) to be modified.

[0054] Although the present invention has been described above with reference to the embodiments illustrated in the drawings, this is merely for the purpose of explaining the invention, and those skilled in the art will understand that various modifications or equivalent embodiments are possible from the detailed description of the invention.

[0055] Therefore, the true scope of rights of the present invention must be determined by the technical concept of the patent claims. Explanation of the symbols
