摘要
鉴于传统的柱状采泥器、抓斗式采泥器比重较大,受海流、水深、底质情况制约,采样成功率低的问题,借鉴了船锚的工作原理,研制了锚式表层沉积物采集装置。其重量为抓斗式采泥器的1/3,操作简便,成功率近100%,可以推广使用。该文介绍其结构和工作过程。
One anchor-device sampler for the surface sediment collection was invented since conventional surface sediment sampler was too heavy for cancellation water current, depth, sediment condition and the sampling success rate. The new sampler like boat anchor whose quality was 1/3 of grab sampler＇s. What＇s more, the new sampler was very easy to operate and its success rate was nearly 100%, so it should be applied and popularized. In the paper, the structure and working process were introduced.
