Harbor water exchange channel structure with wave blocking function

The invention relates to a harbor water exchange channel structure with a wave blocking function. The harbor water exchange channel structure is arranged at the target position of a breakwater and isused for water body exchange inside and outside the harbor, and comprises an upper structure and a lower flow passing channel (3), and a bottom protecting structure; the upper structure rests on the breakwater at the two sides of the breakwater gap position, and is composed of a flat plate (1), a wave blocking plate (2), a wave blocking wall (6), a wheel protecting sill (7) and a surface layer (8), and functions of wave blocking, passing vehicles and pedestrians are achieved; the bottom protecting structure is arranged on the seabed surface at the bottom of the breakwater gap position, and isused for preventing the seabed from being flushed by water flow, and the area between the upper structure and the bottom protecting structure is the lower flow passing channel (3); and the fluctuationtidal current flows into a
