Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for persistent organic pollutants. Background Art

[0002] Persistent organic pollutants refer to chemical substances synthesized by humans that can persist in the environment, accumulate through the biological food chain (web), and have harmful effects on human health. They have four characteristics: high toxicity, persistence, bioaccumulation, and long-range migration. For humans at the top of the food chain, these toxicities are magnified by more than 70,000 times compared to the initial level.

[0003] However, in the prior art, the sampling of persistent organic pollutants in soil and sediment usually involves on-site soil collection. When collecting soil, it is usually carried out manually. However, during the collection process, the collection process is complex, delaying the collection efficiency, and the collected samples may be contaminated, thus affecting the accuracy of subsequent detection data. Content of the Utility Model

A second hole 116 is opened at the bottom of the support frame 103. A third hole 117 is opened at the top of the inner wall of the support frame 103

[0027] The effect achieved by the entire Embodiment 1 is that a first hole 102 is opened at the bottom of the outer frame 101, which facilitates installation and fixation. A support frame 103 is fixedly connected to the bottom of the outer frame 101, thereby playing a role in supporting and fixing. A side plate 104 is fixedly connected to one side of the outer wall of the support frame 103, which can facilitate sealing a certain part of the internal space of the support frame 103.

[0030] Working principle: First, move the entire device to the site where detection is required. After the device is placed stably, place the clean sample container 206 inside the placement groove 205 opened at the top of the rotating disk 201. Driven by the motor 107, the threaded lead screw 106 rotates, and thus the sampler 113 at the bottom of the lifting block 109 descends until it inserts into the soil for sampling collection through the second hole 116 opened at the bottom of the support frame 103. After the sampler 113 is filled with soil samples, it is lifted by the drive of the motor 107 again. Manually rotate the rotating disk 201 to rotate one of the sample containers 206 to the bottom of the sampler 113, then lower the sampler 113 to the top of the sample container 206. Finally, drive the push block at the bottom by the cylinder 112 to push the soil inside into the sample container 206. Then, manually take out the sample container 206 containing the sample.
