摘　　要：介绍了一种新型便携式多深度水质采样器的研究背景、工作原理、结构组成,分析了其适用性和应用前景。对已有的简易水质采样器的结构形式、技术特点进行了改进。该采样器的主要优点是可较为精确采集到测验所需水位的水体,并在采水的同时及时避免了污物,而且能够在一次取样中,取到2个不同深度的水样,有效解决了高效多层取水的问题,造价低廉,较为经济,容易配置,适用面较广。the study background, operating principle and structural components of one new portable sampler for water quality at multiple depths are introduced. Its applicability and application prospects are analyzed. The structural modes and technical features of the existing simple water-quality samplers are improved. The new sampler features that water at the required levels can be sampled precisely, trashes and wastes can be avoided while water is sampled. Furthermore, two samples of water at different depths can be collected once. It sam- pies effectively at multiple depths and with characteristics of lower cost, easy arrangement and wide application range.
