Title:
DEVICE FOR DETECTING FRACTURE OF REBAR FOR UTILITY POLE
Document Type and Number:
WIPO Patent Application WO/2017/043752
Kind Code:
A1
Abstract:
The present invention relates to a device for detecting fracture of a rebar for a utility pole, comprising: detection units (10, 40, 60) inserted into an inner space (5) of a utility pole (1) through a hole (3), which is formed on one side of the utility pole (1), such that the same moves while contacting the inner surface of the utility pole (1) and detects magnetic fields of rebars (7, 9) buried in the utility pole (1); a data logger (20) for receiving magnetic field data regarding the rebars (7, 9) detected by the detection units (10, 40, 60) and storing the same; and a fracture status detection unit (30) for detecting the fracture status of the rebars (7, 9) on the basis of the amount of change in magnetic field included in the magnetic field data stored in the data logger (20). The present invention is advantageous in that it is possible to detect the fracture status of the belowground rebar of a utility pole, which is buried in the ground, and it is also possible to detect the fracture status of a plurality of rebars simultaneously.
