An induced draft fan is installed on the center of the right end inside the back box. The lower end of the back box is connected with a hot air pipe. A lead screw is installed in the deicing rod. A driven wheel is installed on the center of the lower end of the lead screw. A driving wheel is engaged with the right end of the driven wheel. A lifting block is installed on the center of the upper end of lead screw. Lifting rods are installed on the left and right ends of the lifting block. A first connecting rod is hinged to the tail end of the lifting rod. A second connecting rod is hinged to the upper end of the first connecting rod. A deicing ring is connected to the upper end of the second connecting rod. A clamping ring is arranged on the inner side of the deicing ring. Deicing teeth are uniformly arranged on the inner side of the clamping ring. Hot air holes areuniformly disposed on the center of the clamping ring. Fixing plates are installed at both ends of the middle of the deicing rod. Fixing rods are mounted on the upper ends of the fixing plates. The rotary power overhead transmission line deicing device clamps a transmission line by the deicing ring, and doubly deices an ice layer on the transmission line, improves a deicing effect, is easy to operate, meets the need for deicing the transmission line, and is practical.
