Compressed air used for driving the lifting rod to move upwards to prevent a cable from being damaged is arranged in the shell, the lifting rod is connected with a pipe through a connecting assembly, a controller and an unlocking device are arranged in the shell, the battery is connected with the controller and used for supplying power to the controller, and the controller is connected with the strain gauge and controls the unlocking device according to data of the strain gauge. Therefore, the unlocking device disconnects the connecting assembly and enables the lifting rod to move upwards. When earth is excavated on the side face, the early warning function can be triggered in time. 本发明公开了一种地下电缆防破坏预警装置，包括壳体、设置在
