Description

Technology Field

[0001] The present invention relates to a device for preventing electric shock accidents for workers during construction electrical work, and more specifically, to a device for preventing electric shock accidents for workers during construction electrical work that prevents electric shock accidents caused by leakage current by detecting and notifying leakage points occurring in cables by the prevention device, prevents leakage current caused by cable damage or sheathing by preventing impact from being transmitted to the cable by the elastic catch support, and improves workability and convenience by allowing workers and construction equipment to move up and down by means of an elevator transport means. Background Technology

[0003] Generally, overhead distribution lines are configured such that a relatively high-voltage crossarm is fixed to the upper part of a utility pole installed at regular intervals along a roadside, and the relatively high-voltage overhead distribution line is supported in an insulated state through a relatively high-voltage insulator installed on the crossarm; a low-voltage crossarm is fixed to the lower part of the relatively high-voltage crossarm, and the low-voltage overhead distribution line is supported in an insulated state through a low-voltage insulator on the low-voltage crossarm; and a pole-mounted transformer is installed between the relatively high-voltage crossarm and the low-voltage crossarm, connecting the relatively high-voltage overhead distribution line to the input terminal of the pole-mounted transformer and the low-voltage overhead distribution line to the output terminal of the pole-mounted transformer, thereby stepping down the high-voltage electricity distributed through the relatively high-voltage overhead distribution line to low-voltage electricity by the pole-mounted transformer and distributing it through the low-voltage overhead distribution line.

[0004] Accidents in which workers are electrocuted frequently occur due to leakage currents in overhead power lines during the installation or maintenance processes of such conventional multi-unit residential buildings.

[0005] However, conventionally, there is no separate device to detect leakage current from overhead power lines in multi-unit buildings, which leads to frequent electric shock accidents for workers. Additionally, there is no separate configuration to support overhead power lines or cushion impacts, which causes leakage current due to cable sagging or external impacts. Furthermore, since workers must move to the location of the overhead power lines to perform work, there is a persistent problem requiring a separate ladder for movement.

[0006] The aforementioned invention refers to background technology in the technical field to which the present invention belongs, and does not refer to prior art. Prior art literature

[0027] The above wall fixing bracket panel (20) is connected and fixed to the wall surface of the multi-unit building (100).

[0028] The above wall fixing bracket panel (20) is made of metal or synthetic resin and is formed into a square panel structure.

[0029] The above wall fixing bracket panel (20) is fixed by screwing or attaching it to the wall surface of the multi-unit building (100).

[0030] One end of the horizontal guide support panel (30) is connected and fixed to the wall fixing bracket panel (20) which is fastened to the multi-unit building (100).

[0031] The above horizontal guide support panel (30) is made of metal or synthetic resin and is formed into a square panel structure.

[0032] The horizontal guide support panel (30) is fixed by screwing or attaching one end to the front of the wall fixing bracket panel (20).

[0033] The upper end of the vertical blocking panel (40) is connected and fixed to the other end of the horizontal guide support panel (30) which is fastened to the wall fixing bracket panel (20).

[0034] The above vertical blocking panel (40) is made of metal or synthetic resin and is formed into a rectangular or square panel structure.

[0035] The upper end of the vertical blocking panel (40) is fixed to the other end of the horizontal guide support panel (30) by being screw-fastened.

[0036] The cable (200) is protected by the vertical blocking panel (40) to prevent external impact from being transmitted to the cable (200) and to prevent the cable (200) from being damaged by external impact.

[0037] In addition, the vertical blocking panel (40) prevents heat from sparking or overheating caused by a short circuit or leakage current generated in the cable (200) from being transmitted to the worker.

[0038] The above lifting and transfer means (50) is connected to and fixed to the vertical blocking panel (40) which is fastened to the horizontal guide support panel (30).

[0040] By driving the lift transfer cylinder (52), the worker riding on the lift platform member (54) is transported up and down, allowing for stable work and placement of work materials, thereby enabling effective work performance and reducing fatigue.

[0041] The above elastic locking support member (60) is connected to and fixed to the vertical blocking panel (40) which is fastened to the horizontal guide support panel (30).

[0042] The above elastic locking support member (60) comprises a guide rail support bar (61) fixed by screwing one end to the inner surface of the vertical blocking panel (40) connected to the horizontal guide support panel (30), a guide support tube (62) movably fitted into the guide rail support bar (61) connected to the vertical blocking panel (40), a cushioning support coil spring (63) fixed by screwing the lower end to the upper surface of the guide support tube (62) connected to the guide rail support bar (61), and a cushioning support panel (64) fixed by screwing the lower surface to the upper end of the cushioning support coil spring (63) connected to the guide support tube (62), thereby supporting the cable (200) by the elasticity of the cushioning support coil spring (63).

[0043] The cable (200) is supported by the elasticity of the above buffer support coil spring (63), thereby preventing the cable (200) from sagging during the work process or after the work is completed, and cushioning the shock transmitted from the outside.

[0050] The above warning guide buzzer (80) is connected and fixed to the above wall fixing bracket panel (20) attached to the multi-unit building (100).

[0051] The above warning guide is fixed by screwing it to the above wall fixing bracket panel (20), and receives a detection signal from the above safety detection sensor (71) and emits a warning sound to warn the worker of overheating or short circuit, thereby preventing the worker from evacuating or accessing the cable (200) and preventing safety accidents from occurring.

[0052] It is preferable to fix a vibrator, which is a vibrator, to the outer surface of the guide support tube (62) by screwing it in.

[0053] The vibration of the above vibrator is transmitted to the guide support tube (62), preventing it from getting stuck while moving along the guide rail support bar (61), and removing foreign matter or moisture attached to the outer and inner surfaces, thereby reducing the cost and time associated with maintenance.

[0054] It is preferable to further attach or fix to the above-mentioned lift step member (54) a friction elastic panel made of an elastic synthetic resin material having friction protrusions formed integrally on its upper surface by screw fastening.

[0060] It is preferable to further form bearing grooves on the inner surface of the guide support tube (62), and to rotatably fit ball bearings into the bearing grooves so that a portion of them protrudes outward.

[0061] The ball bearing is guided on the outer surface of the guide rail support bar (61), thereby preventing friction or jamming during the movement of the guide support tube (62).
