Description

Technical Field

[0001] The utility model belongs to the technical field of sampling devices, and in particular relates to a surface water sampling device. Background Art

[0002] Surface water is generally sampled using a sampler that draws in samples through negative pressure. During sampling, some samples may be located in relatively narrow gaps, such as rock cracks. To take out the samples, the operator needs to put his hands and arms into the cracks and then operate the sampler to take the samples. In this way, when the operator puts his hands and arms into the cracks, they may be scratched by sharp stones around them, which poses a certain safety hazard to the operator during the sampling process. In addition, the operator needs to bend over and lie on the sampling position during sampling, which has poor stability and makes sampling difficult in outdoor environments. Utility Model Content
