Embodiment Construction

[0018] Such as Figure 1-2 As shown, this embodiment provides a manual portable water body water sample layered water sampler, including an external sleeve 14, a fixed handle 0 is arranged on the external sleeve 14, and three piston chambers 17 are arranged in the external sleeve 14 , each piston chamber 17 has a water outlet 5, and a piston 3 is installed inside the piston chamber 17. The piston 3 and the edge of the piston chamber 17 are surrounded by a rubber ring to form a sealing piston, which is respectively installed on the bottom of the piston chamber 17 and above the piston 3. There is a one-way valve 4, and a water collection pipe 7 is connected below the piston chamber 17. There is a scale on the casing wall outside the water collection pipe 7 for reading the depth of water entry. The zero line of the scale is flush with the bottom edge of the external casing. The bottom of the external casing has a connecting buckle 12, through which the connecting buckle 12 is con...

Abstract

The invention relates to a manual portable water body water sample layered water collector, which comprises an external casing, a fixed handle is arranged on the external casing, a piston cavity is arranged inside the external casing, a water outlet is arranged on the piston cavity, and a A piston is installed, and a one-way valve is installed on the piston chamber and above the piston. The piston chamber is connected to the water collection pipe. There is a scale on the outer casing wall of the water collection pipe for reading the depth of the water entry. , connect the bottom cover or the secondary connection through the connecting buckle; there are water inlets at different heights on the water collection pipe, the piston is connected with a linkage rod, the linkage rod is connected to the movable handle, and the movable handle is fixed on the fixed handle through the fixed core ; There is also a dial and a weight above the outer casing, and a pointer is installed on the dial to form an angle meter, which overcomes the inaccurate positioning of the water layer in the shallow water in the field, cumbersome operation, heavy weight, and power drive and other disadvantages.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a manual portable water sample layered water sampler, which is mainly used for collecting water samples of different layers in shallow waters such as lakes and rivers. Background technique [0002] Water body sampling is a prerequisite step for studying the water environment. Due to the influence of temperature, oxygen content, microorganisms and other water body autogenous and natural factors, different water layers will have different biological, physical, and chemical characteristics. In order to explore the differences in each water layer and provide a scientific and reasonable basis for water body protection and governance, it is necessary to conduct stratified sampling research on water bodies. [0003] At present, a large number of layered water collectors need to be powered by themselves, and their structures are complex, costly, or bulky, whi...
