摘　　要：受水电梯级开发运行及生态环境保护措施等影响,我国众多河流干支流水体含沙量大幅减少,给水文泥沙测验造成了不少困难和问题。鉴于此,研制了一种新型双筒式河流悬移质及水质样品采集器,介绍了其总体设计方案、各核心部件及其作用和主要技术参数与制作材料。该采集器的优点是可在不同水流条件、水深处,一次性获得两个满足需求的大容量样品。实际应用结果表明:该采集器在保证取样质量的基础上,节约了劳动成本,降低了作业风险,有效解决了新的水沙条件下悬移质泥沙测验及水质样品取样难题。论文研究成果具有一定的推广价值。Under the influences of cascade hydropower station development and ecological environment protection,a large number of main streams and their distribuaries experience drastic reduction in sediment content,which can be troublesome for sediment sampling.A novel double-cylinder collector for suspended sediment and water quality sampling is introduced,including its general product design,its key components and functions,and major technical parameters as well as raw materials.A major advantage of this collector is that it is able to collect two large vol⁃umesamples at one time under different flow conditions and water depths.The actual application showed that the col⁃lector not only can guarantee sampling quality,but also can reduce the labor costs,lower sampling risks,and effec⁃tively solve the problems of suspended sediment measurement and water quality sampling under new conditions,which has certain popularized and applicable value.
