Abstract

The invention provides a river and lake layered synchronous rapid water collection device. The river and lake layered synchronous rapid water collection device is structurally characterized in that a plurality of water inlet guide pipes are uniformly or non-uniformly arranged on a water collector 1 in a vertical direction, wherein the A water inlet guide pipes 2 at the top of the water collector 1 are sequentially connected by A hoses according to the sequence; the A water inlet guide pipes 2 at the top of the water collector 1, and the B water inlet guide pipes 2 of a water collection bottle 6 are sequentially connected by B hoses; the water collection bottle 6 is connected with a multi-through chamber 7 by a C hose; and the multi-through chamber 7 is connected with a vacuum pump 9 by a D hose. The river and lake layered synchronous rapid water collection device has the advantages that a phenomenon that a traditional water collector is easily influenced by wave current movement to deviate from a pre-set sampling point can be effectively overcome, and water samples with different depths are accurately collected; meanwhile, the sampling of the water samples with the different depths is carried out at the same time and the consistency of sampling time is guaranteed; the operation is simple, the sampling time is short and the sampling efficiency is high; and the device is durable and is not easy damage, and is suitable for being repeatedly used outdoors for a long period.

Description

technical field [0001] The invention relates to a layered synchronous rapid water collection device suitable for rivers and lakes, and belongs to the field of water sample collection equipment manufacturing. Background technique [0002] Water sample collection is an important part of the water quality analysis of rivers and lakes. Due to the influence of its own characteristics and external disturbances, the sediment and other substances in the water body have different distribution and change laws along the water depth direction. In order to explore the distribution characteristics of sediment in water bodies and the migration and transformation laws of various pollutants, accurate vertical stratified sampling of water bodies is an indispensable technical support. Therefore, accurate collection of water samples at different depths is a key means to scientifically grasp the law of water quality changes, and is the basis and premise for studying water quality changes in rive...
