Technical Field
The invention relates to a water quality monitoring technology, in particular to a stopping mechanism and an outdoor water quality monitoring device thereof.
Background
Water is a source of life, and the quality of water in a common water source directly influences the surrounding environment and the health of drinking groups. With the increasing strictness of environmental regulations, the protection of water quality has been an important work of environmental protection departments. At present, regular water quality spot check and detection are mainly carried out on some water source places, rivers, lakes and the like, so that the quality of the water quality is monitored, pollution is timely discovered, and the water quality treatment effect is detected.
Although a very comprehensive data analysis can be obtained through a laboratory through a periodic sampling detection mode, under the condition of relatively strong fluidity, pollutants are possibly washed away in sampling interval time, so that the pollution of rivers in the later period is difficult to find a source, and responsibility tracing is difficult to perform. In addition, for key water areas, such as water source areas or key lake pollution treatment areas, the pollution treatment areas are generally far away and have large areas. If the sampling period is too long, a great hidden danger obviously exists, particularly in a water source area, once the sampling period reaches below two times in a month, the water quality problem is found later, and thousands of drinkers are damaged healthily at this time. However, if the sampling frequency is too high, a large amount of manpower and material resources are needed, and the method is obviously not suitable for the current basic environment. The existing internet of things is mature, so that the technology of the internet of things can be completely utilized to realize online monitoring of water quality, the sampling frequency is greatly reduced, the cost is low, and the data is acquired in real time, so that the time and the area of water quality change can be confirmed in time, and later-stage research, responsibility pursuit and the like are facilitated.
