The invention belongs to the technical field of water lenses, and particularly relates to a variable-focus water lens device for optical engineering, which comprises a base and a Z-shaped lens barrel, the Z-shaped lens barrel is formed by splicing a first lens barrel and a second lens barrel, rings are arranged on the outer walls of the adjacent ends of the first lens barrel and the second lens barrel, a plurality of bolt assemblies are inserted between the two rings, and a transparent shell is arranged in the Z-shaped lens barrel. The inner walls of the adjacent ends of the first lens cone and the second lens cone are provided with pressing rings, the edge of the transparent shell is connected with a hose, and the other end of the hose is connected with a water injection mechanism. According to the invention, water is injected into the hose through the water injection mechanism, so that convex lenses with different focal lengths can be formed on the transparent shell, when dust on the surface of the transpar
