Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water sample detection, and particularly relates to a water sample collection and detection device. BACKGROUND

[0002] Water sample detection refers to detection of physical properties, detection of metal compounds, detection of non-metal inorganic compounds, detection of organic compounds, biological monitoring, determination of hydrological and meteorological parameters, and detection of bottom material of environmental water bodies (rivers, lakes, reservoirs and underground water) and water pollution sources (domestic sewage, hospital sewage and industrial sewage).

[0003] In the prior art, when water quality is sampled and detected, manual sampling of water quality is usually performed, and the water sample to be detected is placed in the inside of a detection device to complete detection work. However, in areas where water pollution is relatively serious, water pollution changes differently at different water depths. At this time, sampling and detection of water quality at different depths need to be compared, and the traditional manual method cannot meet such a demand. At this time, a mechanical sampling and detection device needs to be used to complete the work. However, when the existing mechanical sampling and detection device samples water quality, a sampling pipe or a storage device enters water quality at different depths. When the sampling pipe or the storage device is used, the water quality samples at different depths may be mixed and mixed. At this time, the accuracy of water quality detection is reduced. Meanwhile, when multi-level water quality detection is performed, the detection port of the detection device needs to be cleaned frequently by the worker. Therefore, a large amount of time is wasted on equipment cleaning, thereby affecting the use effect. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a water sample collection and detection device to solve the problems in the background art.

[0005] The above technical purpose of the present application is achieved by the following technical scheme:
