Dam slope deicing device for pumped storage power station and use method of dam slope deicing device

The invention relates to the technical field of deicing, in particular to a dam slope deicing device for a pumped storage power station, and provides the dam slope deicing device for the pumped storage power station in order to solve the problems that the size of an ice surface punched hole cannot be adjusted according to the radius of a pipeline by a conventional ice breaking device, and the equipment is unstable in working due to the fact that the ice surface is relatively smooth and has no adhesive force during working. Comprising a bottom plate, a vertical plate is arranged at the upper end of the bottom plate, a liftable icebreaking device is arranged on the vertical plate, the icebreaking device comprises a rotatable first disc, a plurality of icebreaking knives are arranged at the lower end of the first disc, and when the first disc rotates, a structure that the icebreaking knives oscillate up and down while rotating circumferentially can be formed; a rotatable two-way threaded rod is further arranged
