A traditional propeller can easily become entangled with floating objects while operating. In this paper, we present a newly developed Electromagnetic-valve-control-based Water-jet Propulsion System (ECWPS) for an unmanned surface cleaning vessel that can be flexibly controlled via a Micro Control Unit (MCU). The double-structure was adapted to the unmanned surface cleaning vessel for floating-collection missions. Computational Fluid Dynamics (CFD) software for operating effect simulation was also used to reveal the working principle of the ECWPS under different conditions. Neglecting the assembly technique, the design level, controlling strategy, and maneuvering performance of the ECWPS reached unprecedented levels. The ECWPS mainly consists of an Electromagnetic-valve Array (EA), pipeline network, control system, and water-jet source. Both CFD analyses and experimental results show that the hydraulic characteristic of the ECWPS was predicted reasonably, which has enormous practical value and development prospects.

传统螺旋桨在操作时很容易被漂浮物缠住。在本文中，我们介绍了一种新开发的基于电磁阀控制的喷水推进系统（ECWPS），该系统可通过微控制单元（MCU）进行灵活控制。双重结构适用于无人值守的表面清洁船，用于漂浮式收集任务。还使用用于操作效果模拟的计算流体动力学（CFD）软件来揭示ECWPS在不同条件下的工作原理。忽略了ECWPS的组装技术，设计水平，控制策略和操纵性能，达到了前所未有的水平。ECWPS主要由电磁阀阵列（EA），管道网络，控制系统和喷水源组成。
