Problems solved by technology

When analyzing water environment samples, it is necessary to sample the water body through tools such as sampling cylinders, and then plan-sampling-analysis-comprehensively obtain information. At present, the structure of the device for sampling water bodies is relatively simple. Sampling comparison requires repeated sampling of water bodies, which not only has low sampling efficiency, but also causes errors in the measurement results caused by the mixing of sampled water bodies, and also has a certain impact on the judgment of the same sampling area

Abstract

The invention discloses a sampling device for water environment sample analysis and a sampling method. At present, a water body sampling device is single in structure, water bodies with different depths need to be repeatedly sampled and compared, and the sampling efficiency is low. The sampling device for water environment sample analysis comprises a measuring rod (1), a first sampling cylinder (2), a second sampling cylinder (3) and a third sampling cylinder (4), wherein the first sampling barrel is fixedly connected with a first adjusting frame (5); the second sampling barrel is fixedly connected with a second adjusting frame (6); the third sampling barrel is fixedly connected with a third adjusting frame (7), the first adjusting frame, the second adjusting frame and the third adjustingframe penetrate through rectangular insertion holes (8) of the measuring rod respectively, puller bolts (9) are screwed into threaded holes in the first adjusting frame, the second adjusting frame andthe third adjusting frame, and the ends of the puller bolts abut against the side surface of the measuring rod. The sampling device is applied to the field of water sampling detection.

Description

technical field [0001] The invention relates to a sampling device and sampling method for water environment sample analysis. Background technique [0002] With the continuous advancement of my country's economic construction, the establishment and improvement of the city's water environment governance system, and the city's expansion and reconstruction projects, these all affect the city's water environment governance system, especially the city's expansion and reconstruction of the city's water environment. Impact. The water environment sample analysis is essential to the water environment detection. The sample analysis is mainly to determine the environmental quality (or pollution degree) and its changing trend through the determination of the representative values ​​of the factors affecting the environmental quality. Environmental monitoring is to track the changes in environmental quality and determine the level of environmental quality through the detection of the conte...
