Multi-depth water sampling device

Abstract

The invention discloses a multi-depth water sample collection device, which comprises a plurality of water suction hoses (1) with different lengths, a peristaltic pump (2) and a first multi-way valve (3), and all the water suction hoses (1) are arranged side by side After passing through the peristaltic pump (2), each suction hose (1) is connected to the corresponding water inlet of the first multi-way valve (3), and one water outlet of the first multi-way valve (3) is used to discharge water samples. The invention has the advantages of simple structure, convenient use, and multi-point flexible sampling with the movement of the ship body.

Description

technical field [0001] The invention belongs to the technical field of water body sample collection experiments, and in particular relates to a multi-depth water sample collection device. Background technique [0002] At present, my country's environmental situation is severe, especially the water resources environment. The water source of many cities comes from lakes, and the water quality of lakes also has a very important impact on their surrounding environment. It can be seen that the monitoring of lake water quality is a very important part of urban environmental protection and improvement. The commonly used automatic water quality sampling boats that can work in lakes are mostly integrated boats, which are large in size and inflexible, and it is difficult to sample at fixed points because of their poor stability. [0003] Chinese patent document CN 203350081 U discloses a fixed-point multi-depth water sample collection device, which includes a sampling pipe, a water p...
