Offshore photovoltaic porous multi-stage wave energy attenuation floating breakwater and mounting method thereof

The invention discloses an offshore photovoltaic porous multi-stage wave energy attenuation floating breakwater and a mounting method thereof, and belongs to the technical field of breakwater lifting. The floating breakwater comprises a fixed seat and an offshore photovoltaic supporting platform, wherein fixed plate assemblies are mounted below the two sides of the fixed seat, and a chain winding roller assembly is arranged in the fixed seat. Sea waves impact one-way valve plug rods on the inner sides of circular through holes, then limiting springs are driven to move, and the function of flow slowing is achieved through movement of the limiting springs; and water flow enters an offshore side wave storage groove cylinder through the circular through holes and is pushed out through an offshore wave pushing plate, and undercurrent makes contact with a lower surge intercepting net for buffering when passing through a connecting chain. 本发明公开了一种海上光伏多孔多级衰减波能浮式防波堤及其安装方法，属于防波提技术领域，包括固定座和海上光伏支撑平台，所述固定座的两侧下方安装有固定板组件，所述
