Description

Anti-electric shock skirt for icicle remover for tunnel {ANTI SHOCK SKIRT FOR TUNNEL ICICLE CRUSHER}

The present invention relates to an electric shock prevention skirt for an icicle removal device for a tunnel, and more particularly, to an electric shock prevention skirt installed in an icicle removal device for a tunnel that crushes icicles generated in a tunnel in which a high voltage cable is disposed.

Recently, there is an increasing trend of electric vehicles operated by electricity, and on railways where these electric vehicles are operated, catenary lines (including jog lines) are installed along the upper part of the railway to supply power to the electric cars, and the catenary lines are installed on the ceiling of the tunnel in the tunnel. Or, it is fixed and installed to an insulator installed on the upper side.

On the other hand, in old tunnels or poorly constructed tunnels, it is a reality that water leakage partially occurs in the ceiling, and even if it is repaired, it is a reality that the water leakage cannot be completely caught. This leakage phenomenon in the tunnel grows as icicles on the ceiling of the tunnel in the winter, and when the icicles touch the catenary, the catenary is short-circuited and the power supply trips, causing the electric vehicle to stop. cannot be guaranteed, so a lot of manpower is put in to remove icicles so that short circuits of catenary wires do not occur in the winter season, and when icicles are confirmed, icicles are removed by live wire work. In this way, in order to remove the icicles in the winter season, safety accidents frequently occur due to the cost required due to the input of a lot of manpower and the removal of icicles during live wire work and electric vehicle operation.

In order to solve the above problem, Korean Patent Registration No. 10-1782533 discloses a system for preventing the generation of icicles in a tunnel through a hot air fan. Referring to FIG. 1, Korean Patent Registration No. 10-1782533 includes a warm air blowing pipe 1 through which warm air generated through a warm air fan is blown out, and the warm air blowing pipe 1 supports a pipe installation frame 2. It is characterized in that the generation of icicles is prevented in advance by controlling the temperature and humidity in the tunnel (T) through. However, as tunnels generally have large entrances, in order to keep the inside of the tunnel at room temperature to block icicles in advance, energy is consumed excessively and initial and maintenance costs are high, making it difficult to actually use them. .

Korean Patent Publication No. 10-2021-0037859 discloses a mobile icicle crushing system for an electric railway tunnel that removes icicles generated in a tunnel. Referring to FIG. 2, in Korean Patent Laid-Open Publication No. 10-2021-0037859, a crushing moving means 3 moving forward and backward in the longitudinal direction of a tunnel T, and a crushing means 4 installed in the crushing moving means 3 ), and is implemented to crush icicles generated at the top of the tunnel by moving along the predetermined path of the crushing moving means 3. However, such a structure that needs to be installed in the tunnel in advance has a disadvantage in that railroad operation must be stopped for maintenance and the device continues to run back and forth when sub-zero weather continues regardless of whether or not icicles actually occur.

In actual field, it is recognized as more reasonable to crush the icicle by visually identifying the location where the icicle is generated through a worker or a mobile machine. However, as described above, in the process of crushing icicles by hand through the icicle removal rod of a pole, an electric shock accident due to falling water flowing through the icicle removal rod may occur, so there is a limit to blocking it in advance. . In addition, in the case of wearing thick insulating gloves to prevent electric shock, it increases the inconvenience of workers, and it is difficult to work while wearing insulating gloves because removing icicles at high locations requires detailed control. there is
