Description

一种多点同步取水样装置 技术领域
本发明属于水文测验领域，具体地涉及一种多点同步取水样装置。
背景技术
天然河流中的泥沙均为非均匀沙，悬移质含沙量和级配的垂向分布是河流动力学及泥沙运动研究的重要课题。为研究悬移质含沙量和级配的垂向分布规律，需要大量采集河流垂线多点含沙水样。在我国多数水文站，受取样装置与观测设施所限，单点积深法为常规取样测沙方法，无法实现同步多点取样，观测结果具有局限性。并且传统的河流分层取样方法需要借助船只到达垂线位置再逐层取样，耗费大量人力物力，并且在山区河流难以实现。
发明内容
为了克服现有技术的不足，本发明提供了一种多点同步取水装置，可实现在河流中多点同步取水样。
本发明的目的是通过以下技术方案实现的：一种多点同步取水样装置，主要包括不锈钢棒、取样管、转盘、微型抽水泵、抽水导管、取水导管、取样瓶、支架、电机和旋转电机。所述不锈钢棒内设有六个圆管，每个圆管均与不锈钢棒的外壁相切；所述取样管分别嵌于六个圆管内，每根取样管的进水口处设有球阀，相邻取样管中的球阀通过连杆两两连接，连杆末端与电机相连，电机固定在不锈钢棒外侧。所述不锈钢棒的上端与转盘连接，所述微型抽水泵设置于转盘上，转盘与旋转电机连接，旋转电机设置于转盘内部；所述抽水导管与微型抽水泵的进水口连接；所述取水导管与微型抽水泵的出水口连接；所述支架表面上设有六个均匀分布的取样瓶，所述支架为圆环结构，不锈钢棒的侧面上设有四根水平支杆，支架中心穿过不锈钢棒由支杆固定。
进一步地，所述抽水导管与取样管之间通过雌雄接口相连。
进一步地，所述取水导管的出水口位于取样瓶的开口上方。
进一步地，六根取样管的进水口距离水面的高度分别为0.2m、0.2H、0.4H、0.6H、0.8H、H-0.2m，其中H为取样处水深。
与现有技术相比，本发明具有如下有益效果：可同步完成河流垂线六点分层含沙水样采集，且操作人员无需入水，无需借助测船，大幅度提高河流含沙水样取样效率，减小采样工作成本。

具体实施方式
下面结合说明书附图对本发明作进一步的说明。
参阅图1，为本发明一种多点同步取水样装置的结构示意图，主要包括不锈钢棒1、取样管2、转盘3、微型抽水泵4、抽水导管5、取水导管6、取样瓶7和支架8。所述不锈钢棒1内设有六个圆管，每个圆管均与不锈钢棒1的外壁相切，相切能够最小化占用不锈钢棒截面积，便于转盘安装；所述取样管2分别嵌于六个圆管内，六根取样管2的进水口距离水面的高度分别为0.2m、0.2H、0.4H、0.6H、0.8H、H-0.2m，其中H为取样处水深，如图2所示。每根取样管2的进水口处设有球阀，如图3，本领域技术人员通过球阀从而控制取样管2开启与闭合，确保获得指定位置的水样，相邻取样管2中的球阀通过连杆两两连接，连杆末端与电机相连，电机固定在不锈钢棒1的外侧，控制连杆抬升与下降。所述不锈钢棒1的上端与转盘3连接，所述微型抽水泵4设置于转盘3上，转盘3与旋转电机连接，旋转电机设置在转盘3内部，电机轴带动转盘转动；所述抽水导管5与微型抽水泵4的进水口连接，所述抽水导管5与取样管2之间通过雌雄接口相连，可自控分离与接合，所述微型抽水泵4的型号为18WG-18，装置通电后，当抽水导管5与取样管2接合，微型抽水泵即开始工作，当抽水导管5与取样管2分离，微型抽水泵即停止工作。所述取水导管6与微型抽水泵4的出水口连接；所述支架8表面上设有六个均匀分布的取样瓶7，所述取水导管6的出水口位于取样瓶7的开口上方，用于采样收集。所述支架8为圆环结构，不锈钢棒1的侧面上设有四根水平支杆，支架8中心穿过不锈钢棒1由支杆固定。
本发明的工作过程为：不锈钢棒1入水前，取样管2进水口处的球阀均处于关闭状态，此时，抽水导管5与取样管2接合，通过水文缆道将不锈钢棒1固定在河流需要取样的垂线上。采样开始，将该装置通电，不锈钢棒1外侧的电机工作带动连杆下降，位于取样管2进水口处的所有球阀均打开，微型抽水泵4开始工作，水样通过取样管2进入抽水导管5，再通过取水导管6流入取样瓶7内，取样瓶7内流入一定水量后，微型抽水泵4断电停止工作，电机控制抽水导管5抬起与取样管2分离，完成一点采样。随后旋转电机工作，自控转盘3带动抽水导管5和取水导管6顺时针旋转30°并停留5秒，这一步是为了排出导管中残留的水。随后自控转盘再次转动30°，抽水导管5与下一根取样管2接合，完成下一点采样。依 次完成六点采样后，自控转盘顺时针旋转30°，通过水文缆道将不锈钢棒1取出水面，运送到岸边，连杆上升，关闭取样管2进水口处的所有球阀，设备断电，取下六个取样瓶，即完成一条垂线采样。
