[Abstract]:As a new type of renewable clean energy, oceanic energy can make a great contribution to the sustainable development of the World Economic Section. Marine aquaculture resources to promote the social development of rigid material demand and food supply to provide the necessary protection. The existing marine ecological aquaculture mostly concentrated in the harbour, most of them adopt mechanized aquaculture. But the harbor culture has become saturated now, and the marine ecological culture has defects in the aspects of structure design, anti-bad environment performance, resisting the impact of wind and waves, and so on. There are still some practical problems such as the difficulty of energy supply of aquaculture auxiliary equipment. In view of these problems, the following contents are mainly studied in this paper. The actual sea condition of marine ecological aquaculture equipment is analyzed, based on marine environmental physics. Based on the characteristics of sea water motion and marine hydrodynamics, the coupling mechanism of ocean wave, current and tidal current in actual sea area is studied. To establish an effective and accurate coupled fluid model. According to the actual situation of offshore ecological culture sea area, combined with the different structural forms in the coupled fluid movement, force and energy capture efficiency. Based on the analysis of traditional breakwater and marine energy capture power generation system, a new flexible protection system for wave dissipation and current reduction is proposed. It is determined that the protection system is mainly composed of floating HDPE pipeline and resistance type oceanic energy capture device. Based on the model similarity criterion, the three-dimensional model of ocean energy capture impeller is established, and the simulation calculation of CFD model is carried out. Based on the hydrodynamic test of the laboratory pool and the corresponding tidal current energy capture test system, the flexible protection system is optimized by comparing and analyzing the experimental results.
