Floating type comb-like wave consumption device with bottom plate and application of device

The invention discloses a floating type comb-like wave consumption device with a bottom plate and application of the device. The floating type comb-like wave consumption device comprises floating bodyunits, a wave stop backboard and the embankment body bottom plate. The floating body units provide floating force for the floating type comb-like wave consumption device and achieve the wave stop function. The wave stop backboard is vertically arranged between the two adjacent floating body units and achieves the function of connecting the floating body units and the wave stop function. The embankment body bottom plate is horizontally arranged between the two adjacent floating body units and achieves the function of connecting the floating body units and the wave stop function. In the floating type comb-like wave consumption device, the length proportion of a floating box body and a plate structure can be optimized and adjusted according to engineering requirements, and the special embankment body bottom plate ca
