Consequently, positioning crossarms in various locations was very cumbersome and dangerous, which limited the ability to install overhead distribution lines in response to diverse installation environments.

[0042] As shown in FIGS. 2 to 4, the above leakage detection mechanism (40) is installed on the crossarm movable member (21) and outputs a leakage detection signal when a leakage is detected. In this embodiment, the leakage detection mechanism (40) can be installed at various locations, such as the crossarm (30), as long as it can detect leakage from the overhead power line (L). Meanwhile, in this embodiment, the leakage detection mechanism (40) can be any ordinary sensor as long as it can detect leakage.

[0043] The above leakage alarm device (50) is installed on the movable member (21) having a winding mechanism (51), a leakage alarm screen (52), and a weight (53), as shown in FIG. 5.

[0044] The above winding mechanism (51) is equipped with a case (51a), a winding motor (51b), and a winding drum (51c) to wind or unwind a notification screen (52).

[0045] The above case (51a) is provided with an opening hole (51a1) that is opened downward and is installed on the lower surface of the reinforcing member insertion part (21a). In this embodiment, the opening hole (51a1) is provided on the lower plate of the case (51a).

[0046] The above winding motor (51b) is installed inside the case (51a). In this embodiment, the winding motor (51b) can be any of the usual driving means as long as it can drive the winding drum (51c).

[0047] The above winding drum (51c) is connected to the winding motor (51b) and rotates by the winding motor (51b). In this embodiment, the winding drum (51c) is connected to the drive shaft (not shown) of the winding motor (51b).

[0049] The weight (53) is installed on the leakage alarm (52) and is located on the outside of the case (51a). In this embodiment, the weight (53) is connected to the other end of the leakage alarm (52). Meanwhile, in this embodiment, the weight (53) may be in the shape of a rod.

[0050] When this leakage alarm device (50) receives a leakage detection signal from the leakage detection mechanism (40), it drives the winding motor (51b) to unwind the leakage alarm screen (52).

[0052] FIGS. 6 to 9 are diagrams illustrating the operation of the present invention. With reference to FIGS. 6 to 9, the operation of the present invention is described as follows.

[0053] The method of visually indicating a short circuit in the present invention is described as follows.

[0054] When the present invention is installed, if the leakage detection device (40) detects a leakage, the leakage detection device (40) transmits a leakage detection signal to the leakage notification device (50).

[0055] Then, as the winding motor (51b) of the leakage alarm device (50) is driven, the winding drum (51c) rotates, and the leakage alarm (52) wound on the winding drum (51c) is unwound, causing the leakage alarm (52) to unfold as shown in FIG. 6. Meanwhile, when the leakage alarm (52) unfolds, the shaking of the leakage alarm (52) is minimized by the weight (53).

[0056] When the leakage warning screen (52) is unfolded in this manner, the occurrence of a leakage can be visibly and quickly notified through the warning message of the leakage warning screen (52).

[0057] Meanwhile, the method of moving the cross arm (30) in the horizontal direction (left and right direction) in the present invention to vary the position of the cross arm (30) according to the installation environment of the overhead power line (L) is described as follows.

[0058] As shown in FIG. 2, if the center of the crossarm (30) is installed on the utility pole (P), overhead power lines (L) can be installed at both ends of the crossarm (30). (See FIG. 7)

[0059] However, depending on the installation environment of the overhead power line (L), the crossarm (30) may need to be used in a cantilevered form.

[0060] In this case, the operator grasps the lower end of the guide pin (23c) and moves the fixing pin member (23) upward so that the first and second fixing pins (23a, 23a') of the fixing pin member (23) detach from the reinforcing member (21) and reinforcing member (30) as shown in FIGS. 7 and 8.

[0061] At this time, the fixing pin member (23) is stably moved upward by the guide pin (23c) and is not detached from the pin guide part (21b) by the stopper (22), so the risk of loss of the fixing pin member (23) is eliminated.

[0062] Afterward, when the position of the reinforcing bar (30) is moved while the reinforcing bar (30) is inserted into the reinforcing bar moving insertion part (21a), and the fixing pin member (23) is inserted into the first and second pin fixing holes (21a2, 21a2') of the reinforcing bar moving insertion part (21a) and the first and second connecting holes (31, 31') of the reinforcing bar (30), the reinforcing bar (30) is fixed to the reinforcing bar moving member (21) as shown in FIG. 9, and the reinforcing bar (30) is arranged in a cantilever shape.

[0064] The present invention, as described above, can notify the outside of the occurrence of a short circuit more quickly and accurately by unfolding the short circuit notification screen (52) to visually indicate the occurrence of a short circuit when a short circuit occurs.

[0065] In addition, the present invention has the effect of allowing the position of the crossarm (30) to be easily moved through simple operation, thereby enabling the crossarm (30) to be arranged in various ways in a simple manner according to the installation environment of the overhead power line (L).

[0066] In addition, the present invention has the effect of conveniently releasing the fixation of the reinforcing bar (30) through the fixing pin member (23), conveniently moving the fixing pin member (23) upward through the guide pin (23c), and conveniently preventing the fixing pin member (23) from coming off through the stopper (22) installed on the guide pin (23c).

[0068] Meanwhile, in the sense that the present invention further includes various structures applicable to overhead power distribution, such as a leakage current notification structure, in a structure for fixing overhead power distribution lines, the title of the invention is defined as "safety-enhancing leakage current detection type overhead power distribution line fixing device," and the subject of the claim is defined as "overhead power distribution line fixing device."
