深远海养殖工船投饲系统设计

Design of automatic feeding system for off-shore aquaculture ship

针对深远海养殖大型化、规模化发展需求,以大型养殖工船为依托平台,基于气力输送原理和自动化控制技术设计了远程自动投饲系统。该投饲系统由上料装置、饲料输送和分配装置、撒料装置以及自动控制装置等组成。系统设计输送管道直径80 mm,最大输送距离为85 m,系统以触摸屏为人机操作界面,以PLC为控制核心,根据投喂不同需求即时调节饲料投放速率和距离。海上试验结果显示,该投饲系统能有效完成工船养殖模式的投喂需求,投饲作业效率为0~40 kg/min,投饲距离为6~9 m。本研究为深远海养殖工船投饲系统研制提供了技术参考。

According to the needs of the large-scale development of marine aquaculture,a remote automatic feeding system is designed based on the principle of pneumatic conveying and automatic control technology.The feeding system is composed of a feeding device,feed conveying and distribution device,spreading device,and automatic control device.The designed diameter of the conveying pipeline is 80 mm and the maximum conveying distance is 85 m.The system takes the touch screen as the man-machine interface and PLC as the control core to adjust the feeding rate and distance in real-time according to different feeding needs.The results of the sea trial test show that the feeding system can effectively meet the feeding requirements of the craft aquaculture mode.The feeding efficiency is 0-40 kg/min and the feeding distance is 6-9 m.This study provides a technical reference for off-shore ship aquaculture.
