Water body layered synchronous sampling automatic device and sampling method

Abstract

The invention relates to an automatic device for layered synchronous sampling of water bodies. The device includes a support circular pipe (1), a sliding water intake pipe (2), a connecting pipe (3), a sampling bottle (5) and a vacuum pump (7), wherein, There are strip-shaped gaps in the longitudinal direction of the support round pipe (1) marked with scale; there are multiple sliding water intake pipes (2), and one end of each sliding water intake pipe (2) is stuck in the strip-shaped gap through the slider and can be Slide up and down, and the other end is respectively connected to the lower water inlet of the sampling bottle (5) through the connecting pipe (3), and the upper gas outlet of the sampling bottle (5) is connected to the vacuum pump (7). The invention also provides a sampling method using an automatic device for synchronous sampling of water layers. The invention can realize layered synchronous sampling of water bodies, has little mutual interference between water bodies of various layers, has high sampling efficiency, has relatively simple overall structure, and satisfies the sampling requirements of water quality environment monitoring of different water bodies.

Description

technical field [0001] The invention belongs to the field of water quality environment monitoring, and relates to an automatic device and a sampling method for layered synchronous sampling of water bodies, which are suitable for layered synchronous sampling of shallow water bodies below the surface of water bodies such as rivers and lakes. Background technique [0002] Sampling of rivers, lakes and reservoirs is an important part of environmental science research and water environment protection and management. Analyzing and studying physical and chemical indicators such as phytoplankton, zooplankton, and pollutants in each layer of water body requires simultaneous collection of water samples in layers. [0003] In the past, general-purpose water sampling devices were mainly used to collect water samples, such as plexiglass water sampling devices, card-type water sampling devices, and multi-channel water sampling devices. Each water sampler basically requires multiple people...
