[0003] The existing water quality analysis device gradually exposes many drawbacks in practical application, one of the most prominent problems is that it cannot automatically detect and automatically clean. When detecting, the operator needs to select the corresponding detection probe according to the index to be detected, and when detecting multiple indexes of water quality, multiple detection probes need to be used, which has great uncertainty and is prone to errors. During the water quality analysis process, the detection probe is in contact with the water for a long time, and impurities, microorganisms and minerals in the water will gradually adhere to it. These attachments not only interfere with the accurate perception of water quality parameters by the detection probe, leading to deviations in detection data, but also may corrode the probe over a long period of time, shorten its service life and seriously affect the accuracy and reliability of the water quality analysis results.

[0004] The cleaning of traditional detection probes is mostly done by workers by putting the detection probe into clean water for cleaning. The entire cleaning process needs to be manually operated by workers, which is low in efficiency, and the cleaned probe needs to be naturally dried, which takes a long time and cannot quickly detect the quality of multiple samples.

[0034] Control program two: after all the indicators of the water quality sample are detected, or before the next water quality sample is detected, there is a water quality detection sensor 2 that is not cleaned and dried; then the work is paused, and the cleaning and drying work of the water quality detection sensor 2 is started, the rotating lifting mechanism 3 drives the water quality detection sensor 2 to be cleaned to move to the cleaning sleeve 54 one by one, and then moves to the air drying sleeve 63 one by one to perform the cleaning and drying work.
