摘　　要：近年来,随着国内外各种大型养殖设施的建造,养殖业开启了进军深远海、拓展湾外海域养殖空间的序幕。为响应潮流和趋势,推动养殖业转型升级,笔者所在研究团队正在研制适应湾外底层水域的大型升降式刚性网箱,同时开发与之相配套的浮式自动投饵系统,以解决该网箱饲料投喂管理等问题。该系统利用内置蓄电池组提供能量来源,通过内置PLC控制程序,离岸式自动实现定时、定点、定量投喂饵料等一系列精确的动作。目前已完成该系统的小型化样机研制并进行初步试验,储料仓总容积为0.23 m^(3),储料总量为164 kg,4个独立控制的储料仓可实现分时段投喂,投饵能力平均约为66.09 kg·min^(-1)(仓门开口尺寸:90 mm×100 mm)。通过初步试验,表明所研制的浮式自动投饵系统基本达到设计要求,具有结构简单、适应恶劣海况性能强、操作便捷、投饵动作精确、故障率低、运行稳定等优点。In recent years,with the construction of various large-scale aquaculture facilities at home and abroad,it has opened the prelude for the aquaculture industry to enter the deep sea and expand the aquaculture space outside the bay.In response to trends to promote the transformation and upgrading of the aquaculture industry,the author s research team is developing large-scale lifting rigid cages that are suitable for the bottom waters outside the bay.In order to solve the problems of feeding management in the net cages culture,we have developed a floating auto-feeding system.The system uses built-in batteries to provide the energy,and offshore automatically realizes a series of precise actions such as timing,fixed-point,and quantitative feeding of bait with the help of a built-in PLC control program.At present,the miniaturized prototype of the system has been developed and preliminary experiment has been carried out.The total volume of the feed bin is 0.23 m^(3),and the total volume of feed storage is 164 kg.The four independently controlled feed bins can realize to feed at different intervals.The average feeding ability is about 66.09 kg·min^(-1)(size of bin door opening:90 mm×100 mm).The preliminary experiment shows that the floating auto-feeding system basically meets the design requirements.It has the advantages of simple structure,strong performance in adapting to harsh sea conditions,convenient operation,accurate feeding action,low failure rate,and stable operation,etc.
