It is connected to the detection device inner upper；
Water inlet manifold and corresponding branch pipe are controlled, sample water is injected；
S2: detecting sample water by detection unit, and will test result and be transmitted to external equipment, completes the inspection to a sample water
It surveys；
S3: detent component unclamps lifting pipe, and cleaning disk body declines along sleeve, and floats on above sample water, opens drainpipe, release
Sample water；
S4: the cleaning disk body declines with the discharge of sample water, falls on the detection container interior bottom portion；
S5: the cleaning disk body is in the first operating mode, and external water-supply-pipe is to lifting pipe injection stable high voltage mixing
Water flow, water flow pass through the ejection assemblies, form high pressure mixing water flow；
S6: high pressure mixing water flows through the runner in over cleaning disk body, and rotation spray diagonally downward projects cleaning disk body；
S7: the thread groove interaction of the high pressure mixing water flow and detection container that eject provides a rotation to cleaning disk
The climbing power turned cleans the inner wall of the detection container in the cleaning disk gradually stable uphill process；
S8: the lifting pipe is along sleeve gradually stable rising, after contact electrode and the first conductive body contact, the cleaning disk body
In the second operating mode, control unit reduces the waterflood injection rate of external water-supply-pipe, injects stabilizing low voltage water flow, the cleaning circle
Disk slowly rises；
S9: after contact electrode and the second conductive body contact, the movement of control unit control card hyte part will be risen by detent component
Pipe clamp drops in the inner upper of detection container, and external water-supply-pipe stops water filling；
S10: opening drainpipe, and cleaning water is discharged, and waits next group of sample water detection.
7. a kind of multi-point water quality sampling method of sampling according to claim 6, which is characterized in that in the step s 7, clear
Floating platform is arranged in the bottom surface of dishwashing body；
The floating platform includes center floating platform and several annulus floating platforms, and the center floating platform is disc-shaped structure, and the annulus is floating
Platform is annular structure, and the center floating platform is arranged concentrically with the cleaning disk body, and the annulus floating platform is around the center floating platform
Center ring is around setting.
