The utility model relates to an internal surface corrosion circumference magnetic flux leakage detection device of filling station's buried tank jar. The purpose is that the device that provides should be able to be walked and carry out magnetic flux leakage detection along the circumference on storage tank jar internal surface is automatic, has detection efficiency height, characteristics that manpower and materials consumption is few. Technical scheme is: an internal surface corrosion circumference magnetic flux leakage detection device of filling station's buried tank jar, its characterized in that the device includes the frame and the drive frame the traction drive subassembly, mounts and is being examined the internal surface of storage tank jar and to being examined the magnetism that carries out magnetic magnetization construction package and go on detecting in the internal surface of storage tank jar to storage tank jar internal surface through magnetic attracting mode " signal conversion and locating
