Power pipeline obstacle removing inspection device and method

The invention provides a power pipeline obstacle removing inspection device. The power pipeline obstacle removing inspection device comprises a shell, a telescopic mechanism, pulleys, inspection equipment and an obstacle removing assembly. A plurality of groups of telescopic mechanisms are annularly mounted on the periphery of the shell, each group of telescopic mechanism comprises a plurality of telescopic rods, and each pulley is rotationally mounted at the end part of each telescopic rod; the obstacle removing assembly comprises obstacle removing pieces and an obstacle removing body, the obstacle removing pieces are mounted on the telescopic rods and located at the set distance in front of the pulleys; the obstacle removing body is mounted on the rear end face of the shell and used for removing obstacles attached to the side wall of the pipeline; when an obstacle which cannot be removed is encountered, the two groups of pulleys in any two opposite directions can relatively apply acting force to support the
