中文摘要:
      针对一种新型的柱式抗风浪环境监测浮标在波浪条件下的水动力特性进行了试验研究。柱式浮标体由舱体、浮架、配重、锚绳组成,通过浮架采集水样,实现垂向不同深度的水质分层监测,可用于海水养殖等海域的环境监测。本文通过物理模型试验,研究多种波浪工况下柱式浮标的运动和锚绳拉力,分析波高、波周期对浮标的横摇、纵摇、摇摆角度、锚绳拉力等水动力特性的影响,得到不同波浪要素下浮标的水动力量化特征参数。结果表明,三向锚绳系缚作用下,浮标运动轨迹受波高的影响较小,垂向运动幅值总体上随周期增大而增大;本文研究条件下,迎波面锚绳的最大拉力受波高的影响较小,但随着波浪周期的增大而减小。总体而言,本文提出的柱式浮标具有较好的抗风浪能力。
英文摘要:
      The hydrodynamic characteristics of a new type of column anti-wind wave environment monitoring buoy under wave conditions are studied. The column body consists of the cabin, the floating frame, the counterweight and the anchor rope. To achieve different depth of water quality monitoring, it collects water samples through the floating frame, also can be used for environmental monitoring of marine aquaculture area. In this paper, the motion of the buoy and the anchor rope tension under various wave conditions are studied through the physical model test. Analyze the influence of wave height and wave period on hydrodynamic characteristics such as roll, pitch, swing angle, anchor rope tension, etc. The hydrodynamic characteristic parameters of the buoy under different wave elements are obtained. The results show that the buoy movement trajectory under the tethering action of the three-way anchor rope is less affected by the wave height, and the amplitude of the vertical movement decreases with the increase of the wave period. Under the conditions of this study, the maximum tension of the wave-facing anchor rope is less affected by the wave height, but decreases with the increase of the wave period. In general, the column buoy proposed in this paper has good ability to resist wind and wave.
