The water outlet pipe 8 is connected with the water outlet of the multi-channel flow tank 2. The water outlet pipe 8 can be led out of the cabinet body 1 and connected with a water storage tank to collect a small amount of wastewater generated in the detection process. The water quality detection sensor and the pressure transmitter 13 are arranged in the multi-channel flow tank 2 and are respectively connected with the controller 14. The sampling pump 4 and the display 15 are respectively electrically connected with the controller 14. The display 15 is preferably a touch screen display, which is convenient for human-computer interaction. The water quality detection sensor is used to collect water quality data of the water sample in the multi-channel flow tank 2 and display the data through the display 15. The pressure transmitter 13 is used to detect the water pressure in the multi-channel flow tank 2 and feed back the sampling water pressure signal to the controller 14 in real time. The controller 14 judges whether the sampling water has an abnormal condition according to the sampling water pressure signal, timely eliminates the water quality data abnormality caused by the water supply problem, and ensures the effectiveness of the detection data of the water quality detection cabinet. The controller 14 can also control the working state of the sampling pump 4 according to the water pressure signal fed back by the pressure transmitter 13, so as to ensure the stability of the water pressure in the multi-channel flow tank 2. The compact multi-parameter water quality online detection cabinet of the embodiment utilizes the multi-channel flow tank 2 to provide a stable state required for water quality detection, and utilizes the sampling pump 4, the rotor flow meter 5 and the pressure transmitter 13 to ensure suitable and stable water pressure and flow in the multi-channel flow tank 2, so as to improve the detection result stability and accuracy of the water quality detection sensor, ensure the effectiveness and reliability of the detection data, realize continuous real-time online detection of water quality, and improve the water quality data acquisition efficiency.

During use, the sampling pump 4 pressurizes the water in the pipeline to a suitable water pressure, so as to ensure that the sampling water can flow stably in each link of the water quality detection. The rotor flow meter 5 is used to adjust the water flow with a suitable flow rate to enter the multi-channel flow channel 2, so as to ensure the optimal detection water flow rate required by each water quality detection sensor. The pressure transmitter 13 arranged in the multi-channel flow channel 2 feeds back the sampling water pressure signal to the controller 14 in real time. The controller 14 judges whether the sampling water is abnormal according to the sampling water pressure signal, and timely eliminates the water quality data abnormality caused by the water supply problem. When the pressure transmitter 13 data exceeds the set range, the controller 14 opens the electromagnetic exhaust valve 7 to exhaust. When the pressure transmitter 13 data returns to the normal range, the water quality data can be normally detected. The effective automatic exhaust of the gas in the multi-channel flow channel 2 can effectively ensure the effectiveness of the detection data of the water quality detection cabinet. The temperature sensor 9, the pH sensor 10, the residual chlorine sensor 11 and the turbidity sensor 12 arranged in series in the multi-channel flow channel 2 collect and analyze a variety of water quality data at the same time, and obtain continuous water quality data, so as to improve the collection efficiency. The controller 14 transmits the collected multi-parameter water quality data to the remote monitoring platform through the wireless transmission module 16, and saves the data in the historical database, so as to allow an operator to analyze and judge the tap water quality.
