Inspection robot for detecting suspended span cable and inspection method thereof

The invention belongs to the technical field of submarine cable detection, and discloses an inspection robot for detecting a suspended span cable and an inspection method thereof.The inspection robot comprises a clamping device, an axial moving device, an underwater propelling device and a detection device; the axial moving device comprises a plurality of axial rolling wheels arranged on the inner wall of the clamping device, the clamping device walks along the surface of the submarine cable through the axial rolling wheels, and the underwater propelling device is arranged on the clamping device and used for achieving underwater movement of the inspection robot. The detection device is used for completing oil leakage and damage detection of the submarine cable. According to the method, the damage condition of the suspended span cable can be detected more accurately and economically, the fault point is positioned, meanwhile, landform detection and flow velocity observation are carried out, and the damage condi
