Description
Technical Field
[0001] The utility model relates to the technical field of water environment monitoring, in particular to a sample collecting device for water environment monitoring. Background Art
[0002] The collection and preservation of water samples is the basis of water pollution control and research. With the passage of time, the accumulation effect of environmental problems has become more and more prominent. How to effectively collect representative water samples has become the key to water environment control and research. A large amount of sedimentary or flocculated pollutants are deposited at the bottom of rivers, lakes, reservoirs and other water bodies, affecting the water quality of the water body, especially in Northeast my country, where the average rainfall over the years is small and the water exchange rate of reservoirs is low. After years of operation, flocculent deposition is common in the lower layer of the reservoir, causing serious pollution. With economic development, many agricultural water reservoirs have been transformed into urban water supply reservoirs. The change in water use goals has greatly improved water quality standards. In actual reservoir operation, many sudden water quality accidents have occurred, and these problems are closely related to the water quality of the lower layer of the water body.
[0003] At present, when sampling in water, a narrow-mouthed bottle with a volume of 2-3 liters is generally used to be placed in a metal frame. Heavy objects (lead, iron or stones) are installed at the bottom of the frame to increase the weight so that the sampler can sink into deep water. The bottle stopper is connected to a thin lead rope with a water depth scale marked on the rope. When the sampler sinks to a predetermined depth in the water, the thin rope is lifted, the bottle stopper is opened, and water can be injected into the bottle. This sampling method can be used for single-point sampling, but not for multi-point sampling. There is a problem of reduced efficiency between collection and release, and direct multi-point sampling inevitably has the problem of mixed pollution. For this reason, we propose a sample collection device for water environment monitoring. Utility Model Content
