海洋探测无人艇:平台设计及应用

Marine survey unmanned surface vessel:platform design and application

海洋探测无人艇应用范围广泛,但无人艇姿态易受风、浪、流、漂浮垃圾等环境因素影响,导致结构损坏、观测数据精度下降等问题。设计了无人艇双体宽甲板平台,多波束测深系统安装在升降机构上,保障最佳航行姿态和换能器安全,提高了采集数据的精度。2020年,该无人艇参与江西应急抗洪救灾堤坝勘察任务,在水流湍急、水质浑浊、漂浮垃圾多等不利环境下,圆满完成14 km堤坝底质勘察任务,共发现4处堤坝风险位置点,为抗洪抢险提供了重要的数据支撑。

Marine survey unmanned surface vessel(USV)has a wide range of applications.However,the attitude of USV is easily affected by wind,waves,currents and floating debris,which may cause structural damage or low precision observation.Double hull and wide deck platform of unmanned surface vessed was designed,and the transducer of multi-beam echo sounder was installed on the lifting mechanism.These designs improved the sailing attitude of the platform,the safety of the transducer and the accuracy of the observed data.In 2020,this USV was participated in the dike-inspection mission of Jiangxi’s emergency flood relief.It successfully inspected the sediment environment of 14 km dike,affected by the unfavorable working conditions like rapid water flow,turbid water and floating garbage.Four risks were located,which provided important data support for the anti-flood campaign.
