The underwater mobile monitoring platform that utilizes marine animals as carriers provides a new solution to address the issues of short endurance, high costs, and bulky size associated with traditional underwater mobile monitoring platforms. Based on most marine animals that have the behavioral habit of long-duration swimming, a micro hydrokinetic energy harvesting system is proposed. This system applies a miniature vertical-axis water turbine as its energy conversion component. The hydrokinetic energy is derived from the relative movement between marine animals and the surrounding seawater. A conceptual design of a novel underwater mobile monitoring platform is presented. A finite element model of the external-rotor permanent magnet synchronous generator is established to comprehensively evaluate the performance of the generator. Numerical simulation is utilized to conduct a comparative analysis of different diversion channel designs. Preliminary water tank experiments show that the designed micro energy harvester can effectively capture the hydrokinetic energy generated by water flow movement. The startup flow rate of the harvester is around 0.16 m s−1. The output power increases with the increase in water flow velocity, reaching a maximum value of ≈57 mW within the range of water flow rate of about 0.2–0.5 m s−1.

用于水下监测的海洋动物运动微型流体动能采集器设计
以海洋动物为载体的水下移动监测平台，为解决传统水下移动监测平台续航能力短、成本高、体积大的问题提供了新的解决方案。基于大多数海洋动物具有长时间游泳的行为习惯，提出了一种微型流体动力能量收集系统。该系统采用微型垂直轴水轮机作为能量转换部件。流体动能源自海洋动物与周围海水之间的相对运动。提出了一种新型水下移动监测平台的概念设计。建立外转子永磁同步发电机有限元模型，综合评价发电机的性能。利用数值模拟对不同导流渠道设计进行比较分析。初步水箱实验表明，所设计的微型能量采集器能够有效捕获水流运动产生的流体动能。收集器的启动流速约为0.16 m s -1。输出功率随着水流速度的增加而增加，在水流速度约0.2~0.5 m s -1范围内达到最大值约57 mW 。
