Description

{Underground distribution line connection type support device equipped with abnormality detection function}

The present invention relates to a support device connected to an underground distribution line equipped with an abnormality detection function.

Generally, in urban centers or large-scale apartment complexes, water and sewage pipes, as well as wires such as high-voltage lines, low-voltage lines, and communication cables, are installed in tunnel-type common outlets and managed collectively.

This tunnel-type utility outlet allows various types of wires and cables to be organized without interfering with each other, and for this purpose, multi-level shelves are installed at regular intervals inside the tunnel-type utility outlet.

Shelves provided to support multiple wires have a wide variety of installation structures, but most of them are configured to prevent interference between wires and prevent them from falling to the bottom of the utility outlet, thereby preventing electric leakage due to inflow water flowing into the utility outlet.

The prior art as a device for supporting such cables includes Patent Registration No. 1209242 (Underground Transmission and Distribution Cable Support Device), in which the cable mounting unit is spaced a certain width apart from the rail to be fixed to the upper part of the utility port. We proposed a configuration that allows for a greater number of cables to be wired and for easy additional wiring while being installed in multiple locations.

However, although the patent of the prior art provides the advantage of easy repair by securing more cable wiring and a wider work space, not only does a slight stretching action occur while maintaining the cable, but it also causes part of the cable to be cut when necessary. Therefore, the cable length becomes shorter, but there is a problem that a separate cable must be connected to compensate for this.

In addition, the conventional technology had a problem of being quite vulnerable to the inflow of infiltrating water because there was no means to detect if infiltrated water was flowing into the power outlet.
