Embodiment 1

[0034] refer to Figure 1-5 , the present invention provides a multi-layer water sample collection instrument, comprising: a water collection tube 1; a water suction device is arranged at the bottom of the water collection tube 1, and a gas storage device is provided at the top of the water collection tube 1; the water suction device and the gas storage device are connected to each other;

[0035]A plurality of partition plates 2 are arranged in the water collection cylinder 1, and there are several partition plates 2 in a circumferential array around the center line of the water collection cylinder 1, and a water collection cavity is formed between adjacent partition plates 2 and the inner wall of the water collection cylinder 1, and the water collection cavity A water collection shell 3 is arranged inside, and the outer wall of the water collection shell 3 is in contact with the inner wall of the water collection chamber. The bottom surface of the water collection shell 3 is ...

Embodiment 2

[0059] refer to Image 6 , in order to be able to collect water samples at a specific depth and in different directions, so as to enhance the accuracy of water sample collection at a specific depth, this embodiment proposes a water uniform mechanism, including a water uniform shell 37, an annular groove 38, and a lower water inlet 38 and circumferential water inlet hole 14;

[0060] The inner wall of the uniform water housing 37 is compatible with the outer wall of the water collection cylinder 1, the conical cylinder 8 and the water absorption cylinder 12. The top of the inner wall of the water uniform housing 37 is connected with the outer wall of the water collection cylinder 1 by threads, and the lower water inlet 38 is opened in the water uniform housing. On the bottom surface of the body 37, several circumferential water inlet holes 14 are provided in the uniform water casing 37 around the central line of the water uniform casing 37. The annular groove 38 is opened at th...

Abstract

The invention discloses a multi-layer water sample collector, which comprises a water sampling barrel, wherein a water absorption device is arranged at the bottom of the water sampling barrel, and a gas storage device is arranged at the top of the water sampling barrel; the water absorption device is communicated with the gas storage device; a plurality of partition plates are arranged in the water sampling barrel, a plurality of partition plates are circumferentially arrayed around the center line of the water sampling barrel, a water sampling cavity is formed between the adjacent partition plates and the inner wall of the water sampling barrel, a water sampling shell is arranged in the water sampling cavity, and an outer wall of the water sampling shell abuts against an inner wall of the water sampling cavity; a rubber layer is arranged on a bottom surface of the water sampling shell, and a communicating gap is formed in the rubber layer; a splitter plate is fixedly connected to the bottom of the water sampling barrel, a plurality of splitter holes are formed in a top surface of the splitter plate around the center of the splitter plate in a circumferential array manner, a plurality of splitter holes and a plurality of water sampling cavities are arranged in a one-to-one correspondence manner, conical shells are fixedly connected to the outer walls of orifices of the splitter holes, outer walls of the conical shells abut against inner walls of the communicating gaps, and the tops of the conical shells are located in the water sampling shell.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, environmental treatment and surface water collection of water body samples, in particular to a multi-layer water sample collection instrument. Background technique [0002] Water resources are essential resources for human survival, which can be divided into surface water and groundwater resources. Human production and life are inseparable from the existence of water. At present, water resources are mostly used for rivers, lakes, and reservoirs. Therefore, the protection of surface water resources has become more and more important. In recent years, with the development of industry, water resources have been polluted The problem has also aggravated, which has brought serious harm to human life, and the investment in environmental monitoring in water resources has also continued to increase. Testing water quality is the key to solving the problem of whether water resources are pol...
