摘　　要：现有的振荡水柱式波能发电装置中没有波能收集装置与之相匹配,振荡气室对波浪能的俘获效率偏低,所以系统发电效率不理想。研究提出了一种新型波能收集结构,并通过数值模拟的方法,研究其对波能利用率的影响。将现有的岸式振荡水柱波能发电的气室设置成离岸式,保证气室内具有一定的水面高度,在气室的前部加装抛物面型结构的防波堤,并在其中安置导流板。通过比较增加收集装置前后以及不同收集装置形状时气室内水柱的振荡幅值,最终确定最佳收集结构。数值模拟和实验研究结果表明,这种波能收集装置最大可使振荡气室内水柱的振荡幅度提高约80%,极大地提高了波浪能的利用效率。In current oscillating water column type wave power generation equipment, there is no matched wave energy collection device. While the wave energy collection efficiency of the oscillating air chamber is rather low, resulting in an unsatisfactory power generation efficiency of the system. A new wave energy collection structure is proposed and its wave energy utilization rate is studied with numerical simulation. The air chamber of the current onshore oscillating water column type wave power generation equipment is reset as offshore type and a certain water depth is ensured in it. A paraboloid breakwater structure is installed in front of the air chamber and flow deflectors are installed in it. The oscillation amplitudes of the water column before and after the installation of the collection structure and with different shapes are compared. The best collection structure is thus determined. The results of numerical simulations and experiment studies show that the proposed waver energy collection structure can increase the oscillation amplitude of the water column by 80%, which greatly improves the wave energy utilization rate.
