[0060] The working principle and use process of the present invention: when in use, before installing the water quality sensor body A7 or the water quality sensor body B8, it is convenient to fit the ball head seat 10 with the ring seat 9 on the inner circumference of the end seat 5, and at the same time, the multiple groups of arc blocks 15 on the outer circumference of the ball head seat 10 and the multiple groups of arc grooves 16 on the inner circumference of the ring seat 9 are mutually clamped, which is convenient for installing the ball head seat 10, and the open ends on both sides of the outer circumference of the ball head seat 10 are perpendicular to the water flow direction on the inner side of the cross tube 4, so that the spherical arc surface on the outer circumference of the ball head seat 10 can directly face the water inlet end or water outlet end on the inner side of the cross tube 4, and then take the external thread ring 13 and can be screwed together with the internal thread 12 on the inner side of the end seat 5, so as to facilitate the tightening of the ball head seat 10 inserted into the inner side of the ring seat 9. It can operate more stably, and then it is convenient to place the water quality sensor body A7 and the water quality sensor B on the inner side of the two groups of end covers 6 respectively, and at the same time, the end cover 6 can be fixed to the surface of the end seat 5 on the outer periphery of the two groups of cross tubes 4 by bolts, and the ring body 28 and the ring groove 27 between the end cover 6 and the end seat 5 can fit and connect with each other, so as to improve the tightness after the connection between the two, and then connect the corresponding lines and equipment by wires, so that the water quality sensor body A7 and the water quality sensor body B8 can detect the front-end water quality of the water supply of the water plant, and at the same time, the high-pressure water flow flowing through the inside of the cross tube 4 can directly impact on the outer peripheral arc surface of the ball head seat 10, so that the high-pressure water flow can be diverted along the arc surface, which is convenient for buffering while providing the water quality sensor It has a certain protective effect, and the water flow can easily enter the ball head seat 10 along the open ends on the other two sides and is convenient for the water quality sensor to detect, so that the water quality sensor can detect the water quality at the front end of the water plant more safely and stably. Later, when the water quality sensor is used to detect the front-end water quality of the water plant's water supply, the PLC terminal control cabinet 22 can be used to control and open the shut-off valves 19 on the inner sides of the two groups of pipe seats 2 on the outer periphery of the front-end pipe body 1, so that the water flow inside the front-end pipe body 1 can enter the inner side of the pipe seat 2, and at this time, the solenoid valve A20 on the outer periphery of a group of horizontal pipes 4 between the two groups of three-way pipes 3 can be opened, so that the water flow can enter the inner side of the horizontal pipe 4, so that the water quality sensor body A7 in the horizontal pipe 4 here can detect the water. The water quality is detected, and at the same time, the detection module 23 inside the PLC terminal control cabinet 22 is convenient for detecting the operation information of the water quality sensor body A7, and the feedback analysis module 24 is analyzed, so that the analysis module 24 analyzes the detected information and feeds it back to the PLC terminal control cabinet 22. When the water quality sensor body A7 fails, the PLC terminal control cabinet 22 can timely close the solenoid valves A20 at both ends of the outer periphery of the horizontal pipe 4 here according to the collected information and the analysis results. At the same time, the solenoid valve B21 at the connection between another group of horizontal pipes 4 and the three-way pipe 3 can be started and release the blocked pipe, so that the water flow can enter the horizontal pipe 4 here, so that the water quality sensor body B8 inside the horizontal pipe 4 can continue to detect the water quality.It is convenient to maintain the faulty water quality sensor body A7 while continuing to stably detect the water quality of the water supply front end of the water plant, which is convenient to reduce the impact of the water quality sensor failure on the water quality detection. At the same time, the PLC terminal control cabinet 22 is convenient to upload the fault information to the cloud terminal processor 25, and the cloud terminal processor 25 is fed back to the monitoring platform 26, which is convenient for feedback and warning to the staff, so that the staff can go to the site for maintenance in time.
