[0085]

[0086] FIGS. 9 to 16 are diagrams illustrating the operation of the present invention. With reference to FIGS. 9 to 16, the operation of the present invention is described as follows.

[0087] In this embodiment, normally, with the support (51) and the movable member (52) positioned as shown in FIG. 2, the underground power line (L) is placed on the first and second support members (12a, 12a').

[0088] In this state, when the leakage detection sensor (80) detects a leakage from the underground power line (L), it outputs a leakage detection signal.

[0089] At this time, when the control unit (100) receives a leakage detection signal, the control unit (100) operates the driving device (53b).

[0090] Then, the screw (53a) is rotated in the reverse direction and then rotated in the forward direction by the driving device (53b), so that the transfer assembly (54) moves a certain amount to the left and then returns to its original position to the right.

[0091] Here, when the transfer assembly (54) moves to the left, the support (51) moves to the left as in FIG. 9, and the advanced mechanism (60) penetrates the discharge hole (91b) of the case (91) and the vulnerable part (92b) of the receiver (92) as in FIG. 10.

[0092] Afterwards, when the transfer assembly (54) moves to the right, the support (51) moves to the right as shown in FIG. 11, and the advanced mechanism (60) is removed from the discharge hole (91b) of the case (91) and the vulnerable part (92b) of the receiver (92) as shown in FIG. 11.

[0093] Then, the fluorescent material contained in the receptor (92) passes through the penetrating vulnerable part (92b) and the discharge hole (91b) and is discharged to the bottom of the power conduit (T).

[0094] Therefore, when an administrator inspects the underground power distribution facility, they can detect that a leakage current is occurring in the surrounding area through the fluorescent material marked on the floor of the power conduit (T).

[0095] Meanwhile, the process of arranging and removing (replacing) the underground power line (L) in this embodiment is described as follows.

[0096] First, this embodiment is set up with the movable platform (52) positioned as shown in FIG. 12.

[0097] Afterwards, with the underground power line (L) inserted into the inclined roller (20), vertical roller (30), and horizontal roller (40), the underground power line (L) is pulled and moved to a desired position.

[0098] At this time, since the inclined roller (20) is tilted, when the underground power line (L) is pulled and moved forward and backward, the underground power line (L) does not deviate between the vertical roller (30), the horizontal roller (40), and the inclined roller (20) and is stably moved and positioned as shown in FIG. 12.

[0099] However, in this case, when moving the underground power line (L) to the first and second side walls (12, 12') after pulling the underground power line (L) to the desired position, the inclined roller (20) is inclined, so a problem arises in that it is very difficult for the worker to move the underground power line (L) to the first and second side walls (12, 12').

[0100] However, in the case of the present embodiment, after pulling the underground power line (L) to a desired position, when the operator operates the input unit (70) to drive the drive device (53b), the drive device (53b) rotates the screw (53a), and accordingly, the transfer assembly (54) moves to the right.

[0101] At this time, the moving platform (52) moves while pushing the underground power line (L) to the right as shown in Fig. 13, and the underground power line (L) moves upward to the right as shown in Fig. 13, passes over the inclined roller (20), and lands on the first and second support parts (12a, 12a') as shown in Fig. 14.

[0102] Here, by precisely controlling the rightward movement of the movable unit (52) to adjust the position of the underground power line (L), the underground power line (L) can be accurately and conveniently placed at the desired location.

[0103] In addition, in this embodiment, the installed underground power line (L) can be conveniently removed.

[0104] For example, when an underground power line (L) needs to be replaced, with the movable platform (52) positioned as shown in FIG. 12, the worker separates the movable platform (52) from the support platform (51) and then uses the handle (51b) of the support platform (51) to move the support platform (51) to the right of the underground power line (L) to be removed.

[0105] Then, the operator operates the input unit (70) to drive the drive device (53b), thereby moving the transfer bundle (54) to the right of the underground power line (L) to be removed.

[0106] Afterwards, the operator inserts the movable unit (52) into the support (51) so that the movable unit (52) is positioned to the right of the underground power line (L) as shown in FIG. 15, and then operates the input unit (70) to drive the driving device (53b) to move the transfer assembly (54) to the left.

[0107] Then, the underground power line (L) moves as shown in Fig. 15 and is placed on the inclined roller (20) as shown in Fig. 16.

[0108] At this time, the worker pulls the underground power line (L) forward or backward so that the underground power line (L) is removed (separated) from the tray device (10).

[0109]

[0110] The present invention as described above has the effect of preventing safety accidents caused by leakage current by indicating the leakage current through a fluorescent material when leakage current occurs from an underground power distribution line (L).

[0111] In addition, the present invention has the effect of easily replacing the receptor (92) by installing the receptor (92) in a case (91) so that it can be inserted and removed.

[0112] In addition, the present invention has the effect of allowing underground power distribution lines (L) to be conveniently laid and removed (replaced). That is, the present invention has the effect of allowing underground power distribution lines (L) inserted between the inclined roller (20), the vertical roller (30), and the horizontal roller (40) and then moving the movable platform (52) to the right, so that when laying the underground power distribution lines (L), the underground power distribution lines (L) can easily ride over the inclined roller (20) by the movable platform (52), thereby allowing the underground power distribution lines (L) inserted into the inclined roller (20), the vertical roller (30), and the horizontal roller (40) to be conveniently moved to the first and second side walls (12, 12'). In addition, the present invention has the effect of allowing the underground power line (L) to be conveniently removed (replaced) because the movable platform (52) can be easily moved and positioned manually, and then the movable platform (52) can be moved to the left via the transfer device (53) so that the underground power line (L) can be easily moved toward the inclined roller (20). Therefore, the present invention has the effect of reducing the labor of workers and improving safety and work efficiency when laying the underground power line (L) and removing (replacing) the underground power line (L).

[0113] In addition, the present invention has the effect of enabling both leakage indication and underground power line (L) movement work using a wire moving mechanism (50), thereby allowing for very efficient use.

[0114]

[0115] Meanwhile, in the sense that the present invention further includes various structures for underground power distribution, such as a leakage detection structure, in a structure in which an underground power distribution line (L) is connected to a tray mechanism (10), the title of the present invention is defined as 'underground power distribution connection mechanism equipped with a safety function capable of detecting leakage', and the subject of the claim of the present invention is defined as 'underground power distribution connection mechanism'.
