Hierarchical water-collecting device applied to rivers, lakes, reservoirs and canals

The invention belongs to the technical field of water sample collection, and discloses a hierarchical water-collecting device applied to rivers, lakes, reservoirs and canals. A water collection barrelis connected with a steel wire rope through an embedded connection ring; a water tube is directly connected into the water collection barrel; the water tube is connected with the steel wire rope through a loop; the tail end of the water tube is connected with a water pump; the steel wire rope, the water tube and the loop are accommodated into a recovering device. Compared with the conventional device, the device has the advantages of higher water sampling accuracy and more reliable result; moreover, the water sampling efficiency is increased, and time and labor cost are reduced; moreover, thedevice can be applied to a plurality of environments such as rivers, lakes and canals, can be used without assistance of a ship body, and has a wider application range. 本发明属于水样采集技术领域，公开了种用于河湖库渠的分层采水装置，集水筒通过镶装的连接环连接钢丝绳；水管直接接入集
