The invention discloses a snow removal device of a cable. The snow removal device comprises a frame, wherein the frame is a U-shaped metal plate, two first gears are arranged at two outer sides of anupper end of the frame by rotation shafts, an inverse L-shaped baffle plate is inwards and fixedly arranged at an inner side of the upper end of the frame, the inverse L-shaped baffle plate and the frame form two grooves with downward openings, a groove wheel is arranged in each groove and shares the same rotation shaft with a first gear, third gears are arranged below the two first gears and areengaged with the first gears, the two third gears are connected by a rotation shaft and are driven by a motor, fourth gears are fixedly arranged on a driving shaft of the motor and are engaged with the third gears, a first connection rod is hinged with an upper end of the baffle plate, a snow push block is hinged with the other end of the first connection rod and is arranged in front of the frame,a rectangular block with an arc groove is arranged at a lower end of the snow push block, and the first connection rod is hinged with an upper end of the snow push block. By the snow removal device,a traditional snow removal mode of the cable is substituted, the snow removal effect is good, and the personal risk is reduced.
