Floating type horizontal plate wave dissipation structure

The invention belongs to the field of technical research of a wave dissipation structure, and discloses a floating type horizontal plate wave dissipation structure which comprises a horizontal plate. The flexible plate is arranged above the horizontal plates and is configured to define a buffer area chamber between the horizontal plates; the floating plate is arranged on the bottom face of the horizontal plate, a plurality of expansion cavities are defined in the floating plate in the movement direction of sea waves, expansion wave dissipation mechanisms are arranged in the expansion cavities, when the sea waves pass through the expansion cavities, the expansion wave dissipation mechanisms can generate expansion protrusions, and the expansion protrusions move in the radial direction of the expansion cavities to form plunger pressure; wherein a plurality of through holes are formed in the horizontal plate, the through holes are configured to communicate the expansion cavity with the buffer area, when sea waves
