More specifically, the device allows for the identification of the location of pipes containing cables, thereby facilitating maintenance and response in emergency situations. Additionally, the device cushions the transmission of shock to the pipes and cables through a settling buffer support and a lifting elastic fixing part, prevents the cables containing the pipes from sagging, improves support and fixing strength, and enables rapid maintenance by detecting and transmitting when the pipe moves due to external shock or sagging. Background Technology
[0003] Generally, electricity produced at power plants is supplied to the demand side through above-ground substations, corresponding transmission lines, above-ground lines, and underground electrical manholes.
[0004] In the case of supplying power to a demand-side building (apartment building) on the ground through a cable buried underground, the cable buried underground is pulled out to the ground near the outer wall of the building on the ground side, routed up along the outer wall, and brought into the interior through the entry point.
[0005] However, power cables in multi-unit dwellings are placed inside conduits to supply power, but since there is no separate device to verify the location of the conduits, there is a problem where excessive time is required to locate the conduits for maintenance. Furthermore, because there is no separate means to protect the conduits, problems persist where conduits are damaged by external forces, or cables placed inside are damaged or their insulation is damaged, leading to fires or electrical short circuits.
