Sampling module and outdoor water quality monitoring device thereof

Abstract

The invention relates to a sampling module and an outdoor water quality monitoring device thereof. The sampling module comprises a sampling support, which is fixedly arranged on the top surface of a second partition plate and located between a first partition plate and the second partition plate. A water diversion ring is fixed in the sampling support; a drainage groove is formed in the inner sideof the water diversion ring, and the inner side of the water diversion ring is provided with a switching disc in a sealed and circumference manner. A first drainage channel and a second drainage channel are formed in the inner side of the switching disc; one end of the second drainage channel communicates with the top of the first drainage channel; the other end of the second drainage channel runs through the switching disc; the first drainage channel and the switching disc are coaxial, and the bottom of the first drainage channel and the top of a water conduit are assembled in a circumferentially-rotating and sealed mode; the water conduit is internally of a hollow drainage inner pipe; the bottom of the drainage inner pipe communicates with one end of a drainage pipe and one end of a water inlet pipe; the other end of the drainage pipe is led out of a housing and is lower than the lowest positions of the bottom plate and the drainage inner pipe; the other end of the water inlet pipeis sequentially communicated with a first one-way valve and a water pump and then, communicated with a water inlet head; and one side of the water inlet head is communicated with the water inlet pipe.

Description

technical field [0001] The invention relates to water quality monitoring technology, in particular to a sampling module and an outdoor water quality monitoring device thereof. Background technique [0002] Water is the source of life, and the quality of water in general water sources directly affects the surrounding environment and the health of drinking groups. With the increasingly stringent environmental protection regulations, the protection of water quality has become an important task of the environmental protection department. At present, it mainly conducts regular water quality spot checks and tests for some water sources, rivers, lakes, etc., so as to monitor the quality of the water, and at the same time detect pollution in time and test the effect of water quality control. [0003] Although a very comprehensive data analysis can be obtained through the laboratory through regular sampling and testing, in the case of relatively strong fluidity, the pollutants may h...

AI Technical Summary

Problems solved by technology

[0003] Although a very comprehensive data analysis can be obtained through the laboratory through regular sampling and testing, in the case of relatively strong fluidity, the pollutants may have been washed away within the sampling interval, which makes it difficult to pollute the river in the later stage. Once the source is found, it will be difficult to pursue accountability

In addition, for key water areas, such as water sources or key lake pollution control areas, they are generally remote and large in size.

If the sampling period is too long, there are obviously great hidden dangers, especially in water sources. Once the sampling period reaches less than twice a month, it will be too late to discover water quality problems. At this time, thousands of drinkers have already been affected damage to health

However, if the sampling frequency is too high, it will require a lot of manpower and material resources, which is obviously not in line with the current basic environment.
