The invention discloses a power drum type ice guide cable for a river channel in a cold region. The power drum type ice guide cable is obliquely arranged on the downstream side of an ice discharging channel, forms an included angle with a main channel, and consists of an upper anchoring pile, a lower anchoring pile, motors, drums, a drum rotating shaft, an upper steel wire rope and a lower steel wire rope. Each drum is a cylinder, and the surface is uneven, the drum is composed of a drum floating body, a drum body and a drum weight which are sequentially connected from top to bottom, the motoris arranged in the drum body, the drum rotates by taking the drum rotating shaft as the center under the action of the motor, and the upper steel wire rope and the lower steel wire rope are fixedly connected with the upper and lower ends of the drum rotating shaft. The N drums are connected in series through the upper steel wire rope and the lower steel wire rope to form the drum type ice guide cable, N is a positive integer larger than 2, and the two ends of the upper steel wire rope and the lower steel wire rope are fixed to the upper anchoring pile and the lower anchoring pile located on the two sides of the river channel through fixing buckles respectively. The ice guide cable can effectively avoid the accumulation of a large amount of ice and ensure the water delivery safety in the ice period.
