The invention relates to a water turbine water guide blade connecting lever structure connected with a movable water guide blade of a unit. The problems that in the overhauling process, connection between an existing water turbine connecting lever and a movable water guide blade of the unit wastes time and labor, the efficiency is low, equipment is prone to being damaged, and accidents happen are solved. The water turbine water guide blade connecting lever structure comprises a guide blade flap arm connected with a water guide blade shaft head and a connecting plate connected between the guide blade flap arm and a connecting rod assembly; the water turbine water guide blade connecting lever structure is characterized in that the guide blade flap arm is provided with a barrel matched with the water guide blade shaft head, and the barrel is provided with a through groove in the axial direction so as to form a two-flap structure; a shroud ring body is also arranged at the position, matched with one end of the barrel of the guide blade flap arm, of a connecting plate; the shroud ring body is also provided with a through groove to form a two-flap structure, and a locking bolt is arranged on the connecting plate; a split key is arranged at the matching part of the guide blade flap arm and the water guide blade shaft head in the axial direction. The water turbine water guide blade connecting lever structure is convenient and rapid to disassemble and assemble; host machine equipment damage caused by clamping of guide water blades is prevented, the labor intensity is reduced, the working efficiency is improved, and the safety of persons and equipment is guaranteed.
