Description

Technical Field

[0001] The utility model belongs to the field of samplers, and in particular relates to a sampler for environmental detection. Background Art

[0002] Water environment monitoring uses physical, chemical, and biological techniques to conduct qualitative, quantitative, and systematic comprehensive analysis of pollutants and their related components within the water environment, in order to explore and study the changing patterns of water quality. Water environment monitoring provides reliable basic data for water environment management and a scientific basis for evaluating the effectiveness of remediation measures.

[0003] The patent application with publication number CN212432674U discloses a sampler for fine chemical water environment detection, comprising: a sample storage cylinder, the sample storage cylinder having an open top and a closed bottom, a support plate provided on the outer side of the top of the sample storage cylinder, a connecting rod provided inside the sample storage cylinder, a handle provided on the top of the connecting rod, a limit rod provided at the bottom of one end of the handle penetrating the support plate, a spring provided on the outer sleeve of the limit rod, the spring being located between the handle and the support plate, a cover provided on the bottom end of the connecting rod penetrating the bottom of the sample storage cylinder, the inner wall of the cover slidingly fitting with the outer wall of the sample storage cylinder, and a plurality of water inlet holes provided on the outer wall of the bottom of the sample storage cylinder. The beneficial effects of the present utility model are: it can prevent larger impurities in the water source from being sucked into the sampler during sampling, facilitates cleaning of the sampler, and can conveniently realize single-handed operation of the sampler for sampling, ensures the stability of the center of gravity of the staff, and prevents the staff from falling into the water source.

[0004] However, the above technology has the following disadvantages when used:

[0005] 1. From the description in paragraph 0020 of the above document, “the sealing cap 7 is removed from the bottom of the sample storage tube 1, exposing the water inlet 8 to the outside. At this time, the sample storage tube 1 is inserted into the water source, and the water sample will enter the sample storage tube 1 from the water inlet 8. After the sampling is completed, the force of holding the handle 4 and the support plate 2 is reduced, and the spring 6 pushes the handle 4 away from the support plate 2, so that the handle 4 drives the connecting rod 3 to move up and put the sealing cap 7 on the bottom of the sample storage tube 1, and seal the water inlet 8 to prevent the water sample from leaking, and the sampling is completed. The entire sampling process can be operated with one hand, which is convenient and labor-saving, ensuring the stability of the center of gravity of the staff during sampling, and protecting the safety of the staff”, it can be seen that the water sample needs to enter the interior of the sample storage tube through the water inlet 8, and the water inlet 8 will be blocked after long-term use, which will cause the sample storage tube 1 to be unusable.

[0006] Therefore, a sampler for environmental detection is proposed to solve the above-mentioned drawbacks. Utility Model Content
