摘　　要：随着海洋牧场建设向纵深发展,对海洋生态环境、渔业资源进行动态监测和评估变得尤为重要,移动式自主监测是可行方案之一。针对现有监测方式效率低、灵活性差、成本高、运输投放困难等问题,提出了可搭载多类型监测设备的组合式无人监测船。进行了船体结构设计和监测仪器安装机构设计,考虑船体吃水载重及平稳性进行了配重机构设计;基于计算流体力学方法对船体阻力性能进行仿真计算并完成了水下推进器选型,对无人船连接桥结构受到浪高海况的影响,进行了静力学强度有限元分析,船体结构强度能够抵抗4级海浪。对样机开展了试验验证,试验结果表明:无人监测船各机构工作运行稳定无干涉,设计吃水深度0.25 m,航速达2.5 m/s,能够胜任海洋牧场工作海况;监测设备搭载后工作稳定,可实时监控水下渔业资源、勘探水底地形、监测水体pH、温度和溶解氧等数据。该研究为海洋动态、实时监测及数字化提供了技术支撑,为海洋牧场组合式无人监测船的设计研究提供了一种低成本高可靠的实施方案。With the in-depth development of marine ranching construction,dynamic monitoring and assessment of marine ecological environment and fishery resources have become particularly important,and mobile autonomous monitoring is one of the feasible solutions.Aiming at the problems of low efficiency,poor flexibility,high cost and difficult transportation and delivery of existing monitoring methods,a combined unmanned monitoring ship equipped with multiple types of monitoring equipment was proposed.The hull structure design and monitoring instrument installation mechanism design were carried out,and the counterweight mechanism design was carried out considering the hull draft load and stability.Based on the computational fluid dynamics method,the hull resistance performance was simulated and calculated,and the underwater thruster selection was completed,and the static strength finite element analysis was carried out on the unmanned ship connecting bridge structure in high waves,and the strength of the hull structure could resist the 4th level wave.The test results show that the unmanned monitoring vessel has stable operation without interference,the design draft is 0.25 m,the speed is 2.5 m/s,and it can be competent for marine ranching work sea conditions.The monitoring equipment works stably after being installed,and can monitor underwater fishery resources,explore underwater terrain,monitor water pH,temperature and dissolved oxygen in real time.This study provides technical support for ocean dynamic,real-time monitoring and digitalization,and provides a low-cost and reliable implementation scheme for the design and research of marine ranching combined unmanned monitoring vessels.
