Technical field
The present invention relates to water quality monitoring technical fields more particularly to a kind of detection of winter water environment to use water intaking vehicle.
Background technique
Water quality monitoring is type, the concentration and variation tendency of each pollutant of pollutant in monitoring and measurement water body, comments
The process of valence water quality condition.Monitoring range is very extensive, including is not contaminated and contaminated natural water（River, river, lake, sea
And underground water）And various industrial water drainages etc..Main monitoring project can be divided into two major classes：One kind is reflection water quality condition
Overall target, such as temperature, coloration, turbidity, pH value, conductivity, suspended matter, dissolved oxygen, COD and biochemical oxygen demand (BOD)；
Another kind of is some noxious materials, such as phenol, cyanogen, arsenic, lead, chromium, cadmium, mercury and organic agricultural chemicals.For objective appraisal rivers and sea
The situation of foreign-water matter needs the measurement for carrying out flow velocity and flow in addition to above-mentioned monitoring project sometimes
When carrying out water quality monitoring operation in winter, the water surface is caused to freeze since temperature is lower, it is therefore desirable to first remove the water surface
Then ice is sampled to water body, when the prior art is operated, be often sampled in the form of manually digging hole, this
Class operation mode is excessively time-consuming and laborious, and if ice face is too thick, and operation is just more difficult, while being easy in operating process
The security risks such as existing ice face cracking are improved for problems needs.
