Description

Technology Field

[0001] The present invention relates to a power distribution line incoming line holder, and more specifically, to a power distribution line incoming line holder capable of ensuring stability and convenience of maintenance by neatly organizing incoming lines connected to a power distribution line. Background Technology

[0002] As is well known, a drop wire is a line that connects the distribution line to the consumer through a pole-mounted transformer.

[0003] In Korea, three 22.9kV high-voltage distribution lines and a neutral line pass through, and from there, it is converted to 220V for household lighting via a pole-mounted transformer and then supplied through the service entrance line.

[0004] Generally, service entrance lines were very intricately tangled on utility poles, which not only spoiled the aesthetics but also posed a problem that could lead to safety accidents for workers performing wiring or maintenance work.

[0005] As a prior art for solving these problems, Korean registered patent No. 10-0870737 (registration date November 20, 2008) 'holder for organizing incoming lines of power distribution lines' is disclosed.

[0006] The above prior art is characterized by comprising: a plurality of plate-shaped connecting plates formed to have the same curvature as the utility pole so as to be installed along the longitudinal direction of the utility pole and in close contact with a part of the outer surface of the utility pole; a plate-shaped supporting plate formed to protrude outwardly from the connecting plates and protrude along the longitudinal direction of the connecting plates, with a plurality of insertion holes formed through it for mounting the connecting wires; and a connecting band connecting the connecting plates to each other, having elastic force such that a restoring force acts when the connecting plates are mounted and tensions when the connecting plates are separated so that the connecting plates detach from the utility pole.

[0007] However, the aforementioned conventional technology has a structure in which the incoming line is inserted through an insertion hole and one side of the outer circumference of the incoming line is supported, which not only reduces workability for wiring and maintenance but also has the problem that it is difficult to ensure stability because multiple incoming lines become entangled with each other during strong winds. Prior art literature

[0008] Republic of Korea Registered Patent No. 10-0870737 The problem to be solved

[0009] The present invention has been devised to solve the conventional problems described above, and the objective of the present invention is to provide a power distribution line incoming line holder that can ensure workability, convenience, and stability for wiring and maintenance by neatly organizing the outer circumference of the incoming line connected to the power distribution line over a wide area. means of solving the problem

[0010] To achieve the above objective, the present invention has the technical concept of a holder for supporting an incoming line connected to a power distribution line, comprising: a base frame including a clamp coupled to a utility pole, an upper base slat horizontally connected to the upper part of the clamp and having a guide rack provided on one inner surface of a guide slit formed long in the direction of the utility pole, and a lower base slat horizontally connected to the lower part of the clamp to form a through space through which the incoming line passes in the inner lower part of the upper base slat; a mounting member having a mounting groove formed therein to be extendable in the direction of the utility pole in the through space of the base frame and to support the outer circumference of the incoming line; a fixed frame slidably coupled between the upper base slat and the lower base slat of the base frame to fix the incoming line mounted on the mounting member; and an operating pinion rotatably coupled to the fixed frame to engage with the guide rack and to slide the fixed frame along the base frame.

[0011] The above fixed frame may include a fixed lath vertically positioned between an upper base slat and a lower base slat of the base frame to fix the incoming line by pressing the mounting member in the direction of the utility pole, a lower sliding lath horizontally connected to the lower end of the fixed lath and slidably coupled to the upper surface of the lower base slat, and an upper sliding lath horizontally connected to the upper end of the fixed lath and slidably coupled to the lower surface of the upper base slat.

[0012] The above mounting member may include a mounting portion that is coupled to a fixing lath of the fixing frame and has a mounting groove formed to wrap around the outer circumference of the incoming line, and a support portion that is connected to the upper and lower parts of the mounting portion by a folding line to extend and retract in the direction of the utility pole and is supported by the clamp.

[0013] It may further include an elastic pressure member that slides along the base frame and elastically maintains the pressure state of the fixing frame, which fixes the incoming line mounted on the mounting member.

[0014] The above elastic pressure member may be composed of a tension spring that is connected between the fixing lath of the fixing frame and the clamp of the base frame and elastically maintains the pressure state of the fixing lath pressing the mounting member. Effects of the invention

[0015] According to the present invention implemented by the above-described solution, a mounting member temporarily installed by wrapping the outer circumference of an incoming line with a wide surface area is firmly fixed by the pressure of a fixed frame that slides by the rotation of an operating pinion. This not only allows the incoming line to be safely and neatly arranged, but also provides a very useful effect of ensuring workability and convenience for the maintenance of the incoming line, as the fixed frame slides along the base frame by the rotation of the operating pinion, thereby reducing or widening the gap of the mounting member.

[0017] In order to fully understand the present invention, preferred embodiments of the present invention will be described below with reference to the attached drawings.

[0018] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art.

[0019] Accordingly, it should be noted that the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations, and that identical members may be shown with the same reference numeral in each drawing.

[0020] In addition, detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the invention may be omitted.

[0021] A power distribution line incoming line holder according to an embodiment of the present invention includes a base frame (100), a mounting member (200), a fixed frame (300), and an operating pinion (400).

[0022] The base frame (100) is connected to the utility pole (10) to form the base of the incoming line holder.

[0023] Referring to FIGS. 1 and 2, the base frame (100) includes a clamp (110), an upper base slat (120), and a lower base slat (130).

[0024] The clamp (110) is formed in the shape of a metal tube to be coupled to the outer circumference of the utility pole (10). As shown in FIG. 2, the clamp (110) may consist of a left and right pair that are curved to wrap around both sides of the outer circumference of the utility pole (10). At this time, the pair of clamps (110) are firmly coupled to the outer circumference of the utility pole (10) by fastening a bolt (112) and a nut (113) through a flange (111).

[0025] The upper base slat (120) is made of a flat metal plate and is horizontally connected to the upper side of one side of the outer circumference of the clamp (110). A guide slit (121) is formed in the upper base slat (120) that is long in the direction of the utility pole (10) and penetrates vertically. A guide rack (122) is integrally provided on the inner surface of one side of the guide slit (121) to engage with the operating pinion (400). Optionally, the guide slit (121) may be formed parallel to two points on the front and back of the upper base slat (120) as shown in FIG. 2. An upper guide rail (123) may be formed on the bottom surface of the upper base slat (120) in the direction of the utility pole (10). The outer end of the upper guide rail (123) may be formed to be connected to the inner end of the guide slit (121).

[0026] The lower base slat (130) is made of a metal plate of the same shape as the upper base slat (120) and is horizontally connected to the lower part of one side of the outer circumference of the clamp (110). A through space (140) through which an incoming line (20) passes is formed on the inner side between the lower base slat (130) and the upper base slat (120), and a mounting member (200) is installed therein. A lower guide rail (131) may be formed on the upper surface of the lower base slat (130) in the direction of the utility pole (10). Optionally, the lower guide rail (131) may be formed parallel to two points on the front and back of the upper surface of the lower base slat (130) to guide the sliding of the two fixed frames (300).

[0027] The mounting member (200) is installed in the through space (140) of the base frame (100) so as to be extendable in the direction of the utility pole (10) and functions to mount the incoming line (20).

[0028] Referring to FIGS. 1 and 3, the mounting member (200) includes a mounting portion (210) that is coupled to a fixed frame (300) and has a mounting groove (211) formed to wrap around the outer circumference of the incoming line (20), and a support portion (220) that is connected to the upper and lower parts of the mounting portion (210) by a folding line (230) to extend in the direction of the utility pole (10) and is supported by a clamp (110).

[0029] It is preferable that the mounting member (200) be molded from a synthetic resin material having a predetermined elasticity so that the mounting portion (210) and the support portion (220) form a single unit.

[0030] As shown in FIG. 3, a plurality of semicircular mounting grooves (211) may be formed on the inner surface of the mounting portion (210). The inner diameter of the mounting groove (211) is made to be equal to or slightly smaller than the diameter of the incoming line (20), so that the outer circumference of the incoming line (20) can be wrapped over a wide area and temporarily mounted. A coupling groove (212) is formed in the center of the outer surface of the mounting portion (210) and is rotatably coupled to the coupling projection (311) of the fixed frame (300) described later. To elaborate, since the mounting member (200) can be rotated by the coupling groove (212) which is rotatably coupled to the coupling projection (311), the angle at which the incoming line (20) is mounted can be adjusted.

[0031] The support member (220) is formed in a roughly square frame shape, and the upper and lower ends of the support member (220) are connected to the upper and lower ends of the mounting member (210) by a folding line (230) formed horizontally, thereby extending in the direction of the utility pole (10). That is, as the support member (220) and the mounting member (210) fold along the folding line (230), the space between them decreases or widens, and the space between them expands, thereby performing an extension action.

[0032] The fixed frame (300) is slidably coupled between the upper base slat (120) and the lower base slat (130) of the base frame (100) and functions to fix the incoming line (20) mounted on the mounting member (200).

[0033] Referring to FIGS. 1 and 3, the fixed frame (300) includes a fixed lath (310) vertically positioned between the upper base slat (120) and the lower base slat (130) of the base frame (100) to fix the incoming line (20) by pressing the mounting member (200) in the direction of the utility pole (10), a lower sliding lath (320) horizontally connected to the bottom of the fixed lath (310) and slidably coupled to the upper surface of the lower base slat (130), and an upper sliding lath (330) horizontally connected to the top of the fixed lath (310) and slidably coupled to the bottom surface of the upper base slat (120).

[0034] Referring to FIG. 2, the fixed frame (300) can be slidably coupled to two points, front and back, of the base frame (100).

[0035] The fixed lath (310) is made of a flat metal plate and is positioned vertically between the upper base slat (120) and the lower base slat (130). A connecting projection (311) is provided in the center of the inner surface of the fixed lath (310) so that the connecting groove (212) of the mounting member (200) is rotatably connected.

[0036] The lower sliding lath (320) is made of a flat metal plate and is horizontally connected to the bottom of the fixed lath (310). A lower sliding rail (321) may be provided at the center of the bottom surface of the lower sliding lath (320) so as to be slidably connected to the lower guide rail (131) of the lower base slat (130).

[0037] The upper sliding lath (330) is made of a metal plate of the same shape as the lower sliding lath (320) and is horizontally connected to the top of the fixed lath (310). A pinion hole (331) is formed in the center of the upper surface of the upper sliding lath (330), so that the pinion shaft (410) of the operating pinion (400), which will be described later, is rotatably connected thereto. A rail support (332) may be provided protruding from the inner edge of the upper surface of the upper sliding lath (330) so as to be slidably in contact with the bottom surface of the upper base slat (120). An upper sliding rail (333) may be provided in the center of the upper surface of the rail support (332) so as to be slidably connected to the upper guide rail (123) of the upper base slat (120).

[0038] The operating pinion (400) is rotatably coupled to the upper sliding lath (330) so as to engage with the guide rack (122) of the base frame (100), and functions to slide the fixed frame (300) along the base frame (100).

[0039] Referring to FIG. 3, a pinion shaft (410) is provided at the lower center of the operating pinion (400) and is rotatably coupled to the pinion hole (331) of the upper sliding lath (330), and a shaft hole (420) is formed at the upper end so that the knob shaft (431) of the rotary knob (430) is detachably coupled.

[0040] Referring to the enlarged view shown in the lower part of FIG. 2, the operating pinion (400) is movably coupled to the guide slit (121) so as to engage with the guide rack (122). In short, when the rotary knob (430) is turned in one direction, the operating pinion (400) engaged with the guide rack (122) rotates and moves left and right along the guide slit (121).

[0041] Meanwhile, the inlet line (20) holder according to an embodiment of the present invention may further include an elastic pressure member (500) that elastically maintains the pressure state of a fixing frame (300) that fixes an inlet line (20) mounted on a mounting member (200) by sliding along a base frame (100) by means of an operating pinion (400).

[0042] Referring to FIG. 1, the elastic pressure member (500) can be implemented as a tension spring that elastically maintains the pressure state of the fixed lath (310) pressing the mounting member (200) by connecting between the fixed lath (310) of the fixed frame (300) and the clamp (110) of the base frame (100). Optionally, the tension spring can connect the upper and lower parts between the fixed lath (310) and the clamp (110) respectively to maintain an upper and lower balance. At this time, a loop may be provided in the fixed lath (310) and the clamp (110) to connect the tension spring.

[0043] The operation of the embodiment of the present invention configured as described above will be explained in detail with reference to the attached drawings as follows.

[0044] First, the fixed frame (300) to which the mounting member (200) is attached is slidably connected to the base frame (100), and then the base frame (100) is firmly connected to the outer circumference of the utility pole (10) using a clamp (110).

[0045] Next, the inlet line (20) passing through the through space (140) formed on the inner side of the base frame (100) is inserted into the mounting groove (211) of the mounting member (200) to be temporarily mounted.

[0046] Next, when the rotary knob (430) is turned in the direction of the arrow shown in FIG. 4, the operating pinion (400) engaged with the guide rack (122) rotates and moves along the guide slit (121), and at the same time, the fixed frame (300) slides in the direction of the arrow.

[0047] Then, as the support part (220) and the mounting part (210) are folded around the folding line (230) and the distance between them is reduced, the inlet line (20) is fixed by the mounting member (200) as shown in FIG. 4.

[0048] Afterwards, the fixed frame (300) pressing the mounting member (200) firmly maintains the pressure state of the mounting member (200) by means of the elastic pressure member (500), thereby preventing movement caused by external physical factors such as strong winds.

[0049] Accordingly, according to the embodiment of the present invention described above, the mounting member (200), which is temporarily mounted by wrapping the outer circumference of the incoming line (20) with a wide area, is firmly fixed by the pressure of the fixed frame (300) that slides by the rotation of the operating pinion (400). Therefore, not only can the incoming line (20) be safely and neatly arranged, but the fixed frame (300) slides along the base frame (100) by the rotation of the operating pinion (400), causing the spacing of the mounting member (200) to decrease or widen, thereby ensuring workability and convenience for the maintenance of the incoming line (20).

[0050] The embodiments of the present invention described above are merely illustrative, and those skilled in the art will readily understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0051] Therefore, it can be well understood that the present invention is not limited only to the forms mentioned in the detailed description above.

[0052] Accordingly, the true scope of technical protection of the present invention should be determined by the technical concept of the appended claims, and the present invention should be understood to include all variations, equivalents, and substitutions within the scope of the technical concept defined by the appended claims.
