The utility model provides a mechanical ice remover for a power transmission line. The mechanical ice remover comprises a straight cylindrical shell, a spring guiding mechanism, a compression spring, a beating head, a driving mechanism and a position control mechanism, the front end and rear end of the shell are both provided with rope connection structures, the spring guiding mechanism is slideably arranged in the shell, the rear end of the compression spring is arranged on the spring guiding mechanism, the beating head is used for beating icing on the power transmission line, the rear end of the beating head is arranged at the front end of the compression spring, the driving mechanism is arranged on the shell and connected with the spring guiding mechanism, the driving mechanism is used for compressing the compression spring so that the beating head can beat the icing depending on the elastic potential energy of the compression spring, and the position control mechanism is used for locking or unlocking the spring guiding mechanism or the beating head. According to the mechanical ice remover, the requirement of ice breaking is met, the line is not damaged, the operation is simple, and repeated operation on the ground in a long time can be realized.
