Description

Technical Field

[0001] The utility model relates to the field of environmental detection, in particular to a portable heavy metal sampler for environmental detection. Background Art

[0002] A heavy metal sampler is an instrument used to collect heavy metal elements in soil, water, atmosphere and other environments. It usually includes a sampler, a sample container, a sampling tube and other parts. Different sampler types can be selected according to needs, such as soil sampler, water sampler, etc.

[0003] After searching, Chinese patent announcement number: CN218067115U discloses a portable soil heavy metal sampling device, which relates to the technical field of soil sampling equipment, including a support tube, a sampling barrel is provided at the lower end of the support tube, a push rod is slidably connected inside the support tube, a push plate is slidably connected inside the sampling barrel, the lower end of the push rod is connected to the push plate through a thread, the upper end of the support tube is connected to a limiting hoop through a thread, handles are provided on both sides of the outer surface of the limiting hoop, the upper end of the push rod is connected to a push handle through a thread, exhaust holes are penetrated through the push plate and the upper wall of the sampling barrel, and the heavy metals in the soil are sampled through a sampling barrel made of polyvinyl chloride, and the sampled soil is pushed outward by the push plate, which is convenient for taking out the soil inside the sampling barrel, and the sampling barrel made of polyethylene is in direct contact with the soil to avoid the influence of the metal of the sampler on the sample, thereby ensuring the accuracy of subsequent detection.

[0004] The above device uses a sampling tube made of polyethylene to sample the soil. Although it can avoid the impact of metal sampling on the soil sample, the hardness of polyethylene is lower than that of metals such as iron. When sampling, the sampler also needs to press and step on the sampling tube into the soil. The sampling tube made of polyethylene alone is easier to damage due to its lower hardness than the metal sampling tube. Although the device can push the soil in the sampling tube out for collection, some soil will stick to the inner wall. It needs to be completely cleaned before each sampling to avoid affecting the sample, which is relatively time-consuming. Therefore, a portable heavy metal sampler for environmental detection is proposed to solve the above problems. Utility Model Content
