Cable well identification device

The invention relates to the technical field of electric power inspection, in particular to a cable well identification device which comprises a base, a lead screw, a nut and a driving mechanism, a front rail and a rear rail are arranged in front of and behind the right portion of the base respectively, and the lead screw is rotationally installed on the upper side of the right portion of the base. The device is reasonable and compact in structure and convenient to use, when a cable middle head in a cable well is broken down, generated smoke is recognized by the smoke sensor, the smoke sensor transmits a signal to the control module, the control module enables the driving mechanism to drive the lead screw to rotate, meanwhile, the control module enables the alarm to work, and the lead screw rotates to drive the nut to move upwards; the alarm is driven to penetrate through the well cover hole of the cable well and then is located above the ground, so that inspection personnel can conveniently observe and timel
