Ice breaking and melting device for water conveyance canal

The invention discloses an icebreaking and melting device for a water conveyance canal, and relates to the field of icebreaking of water conveyance canals, the icebreaking and melting device comprises longitudinal transmission mechanisms, a transverse transmission mechanism, an icebreaking mechanism and a rolling and melting mechanism, the longitudinal transmission mechanisms are symmetrically installed on river banks on the two sides of the water surface, and the transverse transmission mechanism is vertically arranged between the two longitudinal transmission mechanisms; the icebreaking mechanism is fixedly mounted on the transverse transmission mechanism, and an icebreaking knife is controlled by a driving group to cut an ice surface up and down; after the ice surface is broken through the ice breaking mechanism, the rolling mechanism controls the overturning guide rod set to turn the rope net body upwards from the vertical state so as to hold ice blocks to the position above the water surface, and then th
