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.

The drainage groove has a plurality of and a plurality of drainage groove D121 evenly distributed on diversion ring D120 circumferencial direction, and every drainage groove D121 communicates with a sampling tube D330 one end respectively, every sampling tube D330 other end respectively with the inside intercommunication of sampling bottle D320, specifically, sampling tube D330 with install on sampling bottle D320 the second check valve D321 establish ties the back get into inside the sampling bottle D320.
The drainage tube D140 bottom is fixed with detects shell D610, detects the inside hollow detection inner chamber D161 that is of shell D610, detect the interior block of inner chamber D161, install detection magnet piece D522 slidable, detect magnet piece D522, float magnet piece D521 and all adopt the permanent magnet to make and its homopolar relative in order to produce the magnetic force of mutual repulsion, it is fixed with reset spring D620 top assembly to detect magnet piece D522 bottom, and reset spring D620 bottom and detection inner chamber D161 bottom surface assembly are fixed, detect inner chamber D161 bottom and be fixed with detection switch D630, and detection switch D630's trigger end is just to detecting magnet piece D522, can trigger detection switch after detecting magnet piece D522 descends to move down, and detection switch D630 chooses for use micro-gap switch and its signal terminal to pass through the signal terminal communication connection of interface board and controller in this embodiment.
At the initial state or when the water pump is not started, the water in the drainage inner tube D141 is discharged through the drainage pipe, so that the floating magnet block D521 moves to the bottommost part under the self-gravity force
The drive detects magnet piece D522 and overcomes reset spring and moves down until triggering detection switch D630, and the controller judges that there is not water in drainage inner tube D141 this moment, then just can start the water pump and sample, and this kind of design mainly is to avoid the water pollution next sampling of last sampling to cause sampling failure or the error is great.
During the use, the water pump starts, with water through the inlet tube pump send to drainage inner tube D141 in, the flow of inlet tube is 3 times big than the flow of drain pipe at least this moment, and water rises from drainage inner tube D141, gets into drainage groove D121 through first drainage channel, second drainage channel in, then gets into in the sampling bottle that corresponds with it through the sampling pipe that communicates with this drainage groove D121 in order to accomplish the sampling. The design structure is simple, and multiple times of sampling can be realized.
