Problems solved by technology
[0002] The detection of volatile or volatile organic compounds in the silt soil at the bottom of the lake can effectively reflect the accumulation of organic pollutants in the lake; The content is very low and cannot truly reflect the accumulation of volatile organic compounds. Therefore, the best sampling site is the deepest part of the soft silt layer. Since the sampling personnel on the shore cannot know where the deepest part of the silt is in advance, they cannot sample to the deepest part. sludge samples from

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] as attached Figures 1 to 9 The detection sampling system of volatile or semi-volatile organic compounds in the shown soil comprises the bullet soil sampler 32 at the bottom of the lake that is bullet-shaped and the tip is vertically downward, and the bullet soil sampler 32 at the bottom of the lake is provided with energy A vertical lifter 31 that drives the lake bottom bullet soil sampler 32 up and down. A horizontal silt surface drop plate 35 is arranged below the lake bottom bullet soil sampler 32. The geometric center of the drop plate 35 is hollowed out with a bullet soil sampler. through hole 38;
[0032] When the lower surface of the silt surface drop plate 35 touched the silt surface at the bottom of the lake, the silt surface supported the silt surface drop plate 35 upwards, and the lifter 31 could drive the bullet soil sampler 32 at the bottom of the...

The invention discloses a system for detecting and sampling volatile or semi-volatile organic compounds in soil, which comprises a bullet-shaped lakebed bullet soil sampler with a vertically downward tip, and a vertical lifter capable of driving the lakebed bullet soil sampler to lift up and down is arranged right above the lakebed bullet soil sampler. A horizontal sludge surface landing disc is arranged below the lake bottom bullet soil sampler, and a bullet soil sampler penetrating hole is hollowed in the geometric center of the landing disc; the deepest sampling part of a soft sludge layer can be accurately sampled, and the accumulation condition of volatile organic compounds can be truly reflected.
Description
technical field [0001] The invention belongs to the field of soil sampling detection. Background technique [0002] The detection of volatile or volatile organic compounds in the silt soil at the bottom of the lake can effectively reflect the accumulation of organic pollutants in the lake; The content is very low and cannot truly reflect the accumulation of volatile organic compounds. Therefore, the best sampling site is the deepest part of the soft silt layer. Since the sampling personnel on the shore cannot know where the deepest part of the silt is in advance, they cannot sample to the deepest part. sludge samples. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a detection and sampling system for volatile or semi-volatile organic compounds in soil, which can sample the deepest silt soil samples. [0004] Technical solution: In order to achieve the above object, the det...
