Full-automatic deviation rectifying device

The utility model discloses a full-automatic deviation rectifying device which comprises two bottom frames, two passive power generation mechanisms, a driving mechanism and a carrier roller set, a bearing support I and a bearing support II are installed on the two bottom frames respectively, and the carrier roller set comprises the carrier roller support I and the carrier roller support II. The carrier roller bracket I is rotationally mounted in the middle of the bearing bracket I, and a carrier roller I is fixedly mounted in the carrier roller bracket I; by using the passive power generation mechanism, when the position of the belt I or the belt II deviates, the belt I drives the transmission wheel I to rotate or the belt II drives the transmission wheel II to rotate, so that the passive power generation mechanism generates electric energy and supplies power to the driving mechanism, and the driving mechanism drives the carrier roller bracket I or the carrier roller bracket II; the belt deviation rectifying
