摘　　要：解决网箱养殖过程中网衣的清洗问题,设计涡旋式网箱清洗设备。应用伯努力方程和动量定理,对设备的水动力学参数进行了计算,通过公式推导和计算机程序模拟,设计出动力圆盘的结构参数及最佳喷水孔尺寸。通过水池模型试验,研究设备的水动力性能,制造出生产样机,并进行了海上清洗实验。结果显示,对藻类及其它附着物清洗效果良好,但对牡蛎及紫贻贝的清洗效果较差,可通过缩短清洗周期或采用其它方法来解决。In order to solve the problem of cage-net cleanup during cage mariculture, this paper explores the swirl current fish-cage cleanup equipment and hydraulics calculation during the design course. Based on the Bernoulli Equation and theorem of momentum, it calculates the construction sizes of the disc with formula illation and computer program simulation. It provides an academic basis for further study on fish-cage cleanup equipment. And a prototype of the equipment is produced for the experiment on the sea. According to the results of the experiment, the equipment is very effective in the cleanup of marine alga, but the cleanup of Oyster and Mussel is not very efficient. This can be solved by shortening the cleanup period or taking other methods.
