Description

Technical Field

[0001] The utility model relates to the technical field of water sample collection, in particular to an intelligent water sample collection device. Background Art

[0002] Collecting natural water samples and analyzing their various physical and chemical indicators is an important part of the physical, chemical, biological, and environmental science research of natural water samples. Biochemical oxygen demand is a comprehensive indicator that represents the content of oxygen-demanding pollutants such as organic matter in water. Generally, organic matter can be decomposed by microorganisms, but microorganisms need to consume oxygen when decomposing organic matter. If the dissolved oxygen in the water is not enough to meet the needs of microorganisms, the water body is in a polluted state.

[0003] Sometimes there are floating objects on the surface of the water area to be tested. The existing water sample collection devices generally have floating objects stuck to the bottom after use, and the floating objects will also be mixed in the water sample, which will affect the test results. Most of the existing automatic sampling devices use a suction pipe to extract water and sample. If the suction force is too large, it will cause the mud and sand on the bottom of the water to be sucked in. To this end, we provide a water sample intelligent collection device to solve the above problems. Utility Model Content
