[0005] However, as the tree (30) grows, its branches and leaves can approach the high-voltage overhead power lines (20) or various electrical facilities installed on the utility pole (1) of the power distribution line. When a tree approaches the power distribution line in this way, there is a problem that it causes serious accidents, such as causing a short circuit or damaging the electrical facilities.

[0006] Conventionally, because there was no device to prevent trees from approaching power distribution lines, methods such as pruning trees using tree pruning cutters or replacing overhead power lines with sturdy AITC (fully insulated) cables were used.

[0007] However, since trees grow continuously every year, pruning must be performed annually; during this process, workers are exposed to the risk of accidents such as electric shock, and there is a problem in that the effectiveness of tree pruning cannot be achieved, particularly when trees grow to the sides or tops of utility poles.

[0008] As such, there is a problem of incurring excessive maintenance costs to prevent trees from accessing power distribution lines, such as by performing tree pruning annually or replacing overhead power lines with expensive AITC cables. Prior art literature

[0050] FIG. 2 is a perspective view of a tree access prevention device for a power distribution line according to an embodiment of the present invention, FIG. 3 is an enlarged view of the fixed assembly area of ​​FIG. 1, and

[0051] Referring to FIGS. 2 and 3, a tree access prevention device (1) for a power distribution line according to one embodiment of the present invention comprises a crossarm fastening part (100) that is fastened to a crossarm (40, see FIG. 7), a vertical support part (200) that is assembled to the crossarm fastening part (100), a prevention net fastening part (300) that is assembled to the vertical support part (200), and a tree prevention net (500).

[0052] Here, one crossbar fastening part (100), a vertical support part (200), and a prevention net fastening part (300) are fixed to the crossbar (40), so they can be called a fixed assembly (2). That is, the tree access prevention device (1) of the power distribution line of this embodiment can be implemented in a form in which a tree prevention net (500) is assembled to the pair of fixed assemblies (2) installed on adjacent poles (30).

[0053] Since the crossbar (40) is typically installed at the top of the utility pole (30), the tree access prevention device (1) for the power distribution line can be installed at a high position. Therefore, the tree access prevention device for the power distribution line can block the branches and leaves of growing trees by covering the trees located between the utility poles (30) with a tree prevention net (500).

[0054] FIG. 4 is an exploded perspective view of the fixed assembly of FIG. 3, FIG. 5 is an enlarged view of the crossarm fastening part of FIG. 2, FIG. 6 is a side view of the state in which a fastening bolt is coupled to the crossarm fastening part of FIG. 2, and FIG. 7 shows the state in which a tree access prevention device of one embodiment of the invention is installed on a power distribution line.

[0055] With reference to FIGS. 4 to 7, the tree access prevention device (1) of the embodiment of the power distribution line will be described in more detail.

[0056] The crossbar fastening part (100) is fastened to the crossbar (40) of adjacent poles (30) and can be made of a pair.

[0057] The reinforcing member (100) may be configured to include a fastener (110) that is coupled to the reinforcing member (40) and an assembly connecting member (120) that is assembled to the vertical support member (200).

[0058] The fastening member (110) may include a pair of fastening plates (111, 112) that surround a reinforcing bar (40) and each have bolt holes (111a, 112b) formed therein, a fastening bolt (113) inserted into the pair of bolt holes (111a, 112b) and the bolt holes (111a, 112b) of the reinforcing bar (40), and a fastening nut (114) mounted on the fastening bolt (113).

[0059] For example, each fastening plate (111, 112) has a rectangular cross-section, and a pair of fastening plates (111, 112) can be spaced apart at a distance where a reinforcing bar (40) can be inserted. A pair of fastening plates (111, 112) can have a 'C' shape in an extended form relative to each other.

[0060] A pair of fastening plates (111, 112) may be coupled such that anti-detachment protrusions (111b, 112b) protrude from the inner side. Thus, when the reinforcing bar (40) is positioned between the fastening plates (111, 112), it can be prevented from coming loose. For example, the anti-detachment protrusions (111b, 112b) may include a rubber material.

[0061] At this time, the bolt holes (111a, 112b) formed in each fastening plate (111, 112) and the bolt holes (111a, 112b) formed in the reinforcing bar (40) can be connected to each other. Subsequently, a fastening bolt (113) is inserted into a pair of bolt holes (111a, 112b) and the bolt holes (111a, 112b) of the reinforcing bar (40), thereby fixing the fastening plates (111, 112) to the reinforcing bar (40). After the fastening bolt (113) is inserted, a fastening nut (114) is mounted on the end of the fastening bolt (113).

[0062] The fastening member (110) may further include an anti-detachment pin (115) inserted into the fastening bolt (113). The anti-detachment pin (115) may be inserted into a pin hole formed through the outer end of the fastening bolt (113).

[0063] Here, the fastening bolt (113) may have a head (113a) shape that can be grasped by a grab stick. Also, the fastening bolt (113) and the fastening nut (114) may be configured to be fastened to a socket.

[0064] Therefore, as shown in FIG. 7, the worker can safely install the crossarm fastening part (100) on the crossarm (40) using an insulating tool such as a live wire stick (S).

[0065] The assembly connection part (120) is formed in a shape that extends from the fastener (110).

[0066] The assembly connection part (120) may include a connection part body (121), a connection plate (123), an assembly bolt (150), and an assembly nut (160).

[0067] The connecting body (212) is coupled to the fastener (110) and may have a block shape.

[0068] The connecting plate (123) consists of at least one and can be coupled to the connecting body (121). In this embodiment, one connecting plate (123) is coupled to the center of the connecting body (121), and multiple connecting holes (123a) may be formed in the connecting plate (123). Although four connecting holes (123a) are shown penetrating the plate, the number, shape, location, etc. of the connecting holes (123a) can be modified.

[0069] The assembly bolts (150) are inserted into the connecting holes (123a) and may have a number corresponding to the number of connecting holes (123a). Of course, considering the fastening force, working environment, etc., the assembly bolts (150) may have a number smaller than the number of connecting holes.

[0070] The assembly nut (160) can be fastened to the assembly bolt (150). The assembly nut (160) may have a number corresponding to the number of assembly bolts (150).

[0071] The assembly connection part (120) including the above-described configuration allows the reinforcing member (100) and the vertical support part (200) to be assembled.

[0072] The vertical support member (200) is configured to support the tree prevention net (500) at a certain height below the crossarm (40). The vertical support member (200) can be called an ‘I-shaped support arm’.

[0073] The vertical support member (200) can be modified to have an appropriate length as needed. For example, the vertical support member (200) can be manufactured in various lengths and then replaced with a size suitable for the installation site, and then assembled and installed on the assembly connection part (120) of the reinforcing member (100).

[0074] The vertical support member (200) is assembled to each reinforcing member (100) and can be made of a pair.

[0075] The above vertical support member (200) may include a support bar (210), a first assembly connecting member (220) coupled to one side of the support bar (210), and a second assembly connecting member (230) coupled to the other side of the support bar (210).

[0079] At this time, the shape of the connecting plate (221, 222) and the connecting hole (221a, 222a) of the vertical support member (200) may have a shape corresponding to the connecting plate (123) of the above-described reinforcing member (100).

[0080] Accordingly, during assembly, the connecting plate (123) of the reinforcing member (100) can be inserted between the connecting plates (221, 222) of the vertical support member (200). Subsequently, the assembly connecting part (120) of the reinforcing member (100) and the first assembly connecting part (220) of the vertical support member (200) can be fixed to each other by fastening an assembly bolt (150) and an assembly nut (160) to the connecting holes (123a, 221a, 222a) formed in the connecting plates (123, 221, 222).

[0081] The second assembly connecting part (230) is positioned in the center of the support bar (210) and may include a connecting plate (231) having a connecting hole (231a) formed therein. The connecting plate (231) and the connecting hole (231a) of the second assembly connecting part (230) may have shapes corresponding to the connecting plates (123, 221, 222) and connecting holes (123a, 221a, 222a) described above.

[0082] The first assembly connecting part (220) and the second assembly connecting part (230) can be arranged in directions orthogonal to each other.

[0083] The second assembly connecting part (230) can be assembled with the prevention net fastening part (300).

[0084] The prevention net fastening part (300) is assembled to each vertical support part (200) and can be made of a pair.

[0085] The prevention net fastening part (300) may include a horizontal bar (310), a third assembly connecting part (340), and a pair of branch bars (320, 330).

[0086] The horizontal bar (310) is positioned in a direction perpendicular to the horizontal bar (310) of the vertical support (200), that is, in a horizontal direction. Likewise, the horizontal bar (310) is manufactured in various lengths and can be replaced and assembled to suit the work site.

[0087] The third assembly connecting part (340) is positioned on one side of the horizontal bar (310) and can be coupled to the second assembly connecting part (230) of the vertical support part (200) described above.

[0088] The connecting plates (341, 342) of the third assembly connecting part (340) each have connecting holes (341a, 342a) formed therein and may be formed as a pair. Likewise, the pair of connecting plates (341, 342) and connecting holes (341a, 342a) of the third assembly connecting part (340) may have shapes corresponding to the connecting plates (123, 221, 222, 231) and connecting holes (123a, 221a, 222a, 231a) described above.

[0089] Accordingly, during assembly, the connecting plates (221, 222) of the vertical support member (200) can be inserted between the connecting plates (341, 342) of the prevention net fastening member (300). Subsequently, the third assembly connecting part (340) of the prevention net fastening member (300) and the second assembly connecting part (230) of the vertical support member (200) can be fixed to each other by fastening an assembly bolt (150) and an assembly nut (160) into the connecting holes formed in the connecting plates.

[0090] The branching bar (320, 330) branches off from the other side of the horizontal bar (310) and may be formed as a pair. For example, the branching bar (320, 330) may be in a shape that is spread out at a certain angle on the horizontal plane, like the horizontal bar (310). Therefore, the above-described protection net fastening part (300) can be called a 'Y-shaped support arm'.

[0091] The prevention net fastening part (300) may further include fastening bolt holes (321, 331) formed through each of the pair of branch bars (320, 330) so that a fixing bolt for fixing the tree prevention net (500) is inserted.

[0092] The tree prevention net (500) can be assembled to a pair of prevention net fastening parts (300).

[0093] That is, after the above-described fixed assembly (2) is installed on the crossbar (40) of adjacent utility poles (30), the tree protection net (500) can be installed on the tree by means of the protection net fastening part (300) of the fixed assembly (2).

[0094] Here, the tree prevention net (500) may be made of a metal mesh with appropriate strength to inhibit the growth of trees. Of course, the tree prevention net (500) may be modified to have other materials such as plastic yarn.

[0095] The tree access prevention device (1a) for a power distribution line according to an embodiment of the present invention, which includes the above-described configuration, can be safely and easily installed at the site by a worker using a live-line stick (S), etc., as shown in FIG. 7.
