Floating breakwater capable of eliminating medium and long period waves and unit of floating breakwater
The invention belongs to the technical field of coast engineering, and particularly relates to a floating breakwater capable of eliminating medium and long period waves and a unit of the floating breakwater. A high-reliability OWC device is integrated with the floating breakwater, waves enter the air chamber from the wave incidence hole, wave energy is gathered in the air chamber, water in the air chamber ascends and descends greatly due to strong resonance, at the moment, the water acts on the perforated energy consumption plate arranged in the air chamber, and the energy consumption of the water in the air chamber is reduced. The water body is converted into turbulent flow through the perforated energy dissipation plate to cause obvious turbulent flow energy dissipation, so that the mechanical energy of the water body is effectively reduced; water columns in the air chamber do heaving motion to cause air above the water body to be strongly extruded, kinetic energy of the water body is converted into internal energy of the air, and the air containing energy passes through the energy dissipation air holes, so that the internal energy of the air is converted into turbulent kinetic energy. The method has the characteristics of high wave absorbing capacity, high reliability, low manufacturing cost and low construction difficulty, and is a novel floating breakwater arrangement scheme suitable for medium-long period wave sea conditions.
本发明属于海岸工程技术领域，具体涉及一种可消中长周期波浪的浮式防波堤及其单元。本发明将可靠性高的OWC装置与浮式防波堤集成，波浪从波浪入射孔进入气室，使波浪能聚集于气室内部，气室内水体因发生强烈共振呈现大幅度升降运动，此时水体将作用到安置于气室内部的开孔耗能板，水体经过开孔耗能板转换为湍流引起明显的湍流动能耗散，有效降低水体的机械能；气室内水柱做升沉运动引起水体上方的空气被强烈挤压，实现水体动能到气体内能的转化，蕴含能量的气体通过消能气孔，实现气体内能到湍动能的转化。本发明具有强消波能力、高可靠性、低造价、低施工难度的特点，适用于中长周期波浪海况下的新型浮式防波堤布置方案。
