[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-6 The present invention discloses a quality-differentiated water supply system capable of maintaining a monitoring probe without stopping the machine or disassembling it, comprising:

[0040] The filtration system consists of a plurality of filtration devices, which are connected step by step to perform graded filtration treatment on raw water;

[0041] Water storage and delivery system, used to store the treated water output from each filtering device and deliver it to each user end;

[0042] A water quality monitoring system, which is composed of a plurality of water quality monitoring probes, which are respectively arranged at the water outlets of a plurality of filtering devices, and are used to monitor the water quality parameters of the treated water output by each filtering device;

[0043] A cleaning system, used to separate each water quality monitoring probe from the water quality monitoring system and clean and rinse each water quality monitoring probe in turn with a cleaning agent and pure water, and discharge the water mixed with the cleaning agent out of the water quality monitoring system;

[0044] The control system is used to process the monitoring data of the water quality monitoring system and adjust and control the filtration system according to the preset water quality standards.

[0045] The present invention adds a cleaning system for cleaning the water quality monitoring probe in the original quality-differentiated water supply system, so that when the water quality monitoring probe needs cleaning and maintenance, it can be separated from the water quality monitoring system by the cleaning system, so that the area where the water quality monitoring probe is located is called a cleaning area independent of the water quality monitoring system, which can ensure that the cleaning system will not contaminate the original treated water during the subsequent cleaning process, and can also enable the entire quality-differentiated water supply system to continue water supply operations without being disturbed by the cleaning system.

[0046] It should be noted that the filtration system and the control system are both mature existing technologies and will not be described in detail here.

[0047] In one embodiment, the water storage and delivery system includes multiple storage tanks, multiple connecting pipes for connecting the storage tanks and the water outlet ends of corresponding filtering equipment, and multiple water pipes for delivering treated water in the storage tanks to the user end, and the water quality monitoring system is connected to each connecting pipe.

[0048] This design allows the filtered treated water to be temporarily stored in the storage tank, avoiding the problem of long waiting time caused by re-filtration when needed, and can also provide a certain redundancy for the differentiated water supply system and improve water supply stability.

[0049] In one embodiment, the cleaning system comprises:

[0050] A plurality of water quality monitoring pipes 1, which are used to be connected with corresponding connecting pipes, and corresponding water quality monitoring probes are located in the water quality monitoring pipes 1, and are used to monitor the treated water flowing through the water quality monitoring pipes 1;

[0051] A plurality of chemical cleaning mechanisms 2 are used to be connected to the corresponding water quality monitoring pipelines 1 to transport cleaning chemicals and pure water into the corresponding water quality monitoring pipelines 1 to clean the water quality monitoring probes;

[0052] A plurality of blocking and isolating mechanisms 3 are arranged in each water quality monitoring pipeline 1 and are used to prevent the chemicals from entering the water storage and transportation system through the water quality monitoring pipeline 1 during chemical cleaning.

[0053] With such a design, during the normal monitoring process, by installing the water quality monitoring probe on the water quality monitoring pipe 1, when the treated water flows through the water quality monitoring pipe 1, the water quality monitoring probe can be used to detect the water quality of the treated water flowing through, so that the detection data obtained by the water quality monitoring probe can accurately reflect the water quality of the treated water. When the water quality monitoring probe needs to be cleaned, the water quality monitoring probe is first separated from the water quality monitoring pipe 1 by the sealing and partitioning mechanism 3, and then different cleaning agents can be delivered to the water quality monitoring probe by the chemical cleaning mechanism 2 to clean the dirt, biofilm, and mineral deposits on the surface of the probe, and finally discharged and collected without causing pollution to the original treated water.

[0054] In one embodiment, the water quality monitoring pipeline 1 includes a main pipe 11 connected to a corresponding connecting pipe, a branch pipe 12 connected to the main pipe 11 and provided with a water quality monitoring probe installed thereon, and a return pipe 13 for water flow in the branch pipe 12 to flow back to the main pipe 11 is provided between the branch pipe 12 and the main pipe 11, and the return pipe 13 is located on the side of the branch pipe 12 close to the liquid outlet end of the main pipe 11;

[0055] A water flow guiding mechanism 4 for isolating the main pipe 11 is disposed in the main pipe 11 . The water flow guiding mechanism 4 is located between the inlet of the branch pipe 12 and the outlet of the return pipe 13 .

[0056] With this design, by installing the water quality monitoring probe at the end of the branch pipe 12, the convenience of disassembling and maintaining the water quality monitoring probe can be improved. Due to the setting of the return pipe 13, the treated water will not only flow along the main pipe 11, but part of the treated water will also flow to the main pipe 11 through the branch pipe 12 and the return pipe 13, ensuring that the data detected by the water quality monitoring probe installed on the branch pipe 12 can be consistent with the water quality of the treated water in the main pipe 11.

[0057] In a specific implementation, a protective cover with filter holes can be added in the branch pipe 12 to reduce the direct impact of water flow on the water quality monitoring probe, and at the same time reduce the interference of suspended matter and sediment in the water on the water quality monitoring data.

[0058] In one embodiment, the blocking and blocking mechanism 3 includes a rotating shaft 31 rotatably disposed in the branch pipe 12, and an arc-shaped plate 32 is disposed on the rotating shaft 31, which can rotate with the rotating shaft 31 and cut off the connection between the branch pipe 12 and the return pipe 13. The blocking and blocking mechanism 3 also includes a fixed baffle 33 fixedly disposed on the branch pipe 12 and located between the water quality monitoring probe and the main pipe 11. The rotating shaft 31 is provided with a movable baffle 34 that rotates with the rotating shaft 31 and cooperates with the fixed baffle 33 to cut off the branch pipe 12. The cross-sectional areas of the fixed baffle 33 and the movable baffle 34 are both smaller than the cross-sectional area of ​​the branch pipe 12.

[0059] A rotation driving assembly for driving the rotation shaft 31 to rotate is disposed at one end of the rotation shaft 31 away from the arc-shaped plate 32 .

[0060] With this design, when the water quality monitoring probe needs to be tested normally, the movable baffle 34 is mostly moved to above the fixed baffle 33 by rotating the rotating shaft 31, and the arc plate 32 no longer cuts off the connection between the branch pipe 12 and the return pipe 13, so that the water flow can flow from the area where the movable baffle 34 is moved to the water quality monitoring probe, and then flow back to the main pipe 11 through the return pipe 13; conversely, when the water quality monitoring probe needs to be cleaned, the movable baffle 34 and the fixed baffle 33 are rotated to cut off the branch pipe 12, and the arc plate 32 cuts off the connection between the branch pipe 12 and the return pipe 13, so that the upper section of the branch pipe 12 where the water quality monitoring probe is installed is separated from the branch pipe 12, so that the subsequent chemical flushing will not contaminate the treated water in the lower section of the branch pipe 12 and the main pipe 11.

[0061] It should be noted that when the movable partition 34 and the fixed partition 33 are in a state of cooperating to cut off the branch pipe 12, the arc plate 32 is also in a state of cutting off the connection between the branch pipe 12 and the return pipe 13, so that the rotating drive assembly can switch the working state by adjusting the rotation angle of the rotating shaft 31 once.

[0062] In one embodiment, the water flow guiding mechanism 4 includes a blocking seat 41 arranged in the main pipe 11 and located between the branch pipe 12 and the return pipe 13. The blocking seat 41 is provided with a through hole for water to pass through. The water flow guiding mechanism 4 also includes a blocking cover 42 arranged on the rotating shaft 31 and capable of rotating with the rotating shaft 31 to block the through hole.

[0063] This design enables the plugging cover 42 to cooperate with the plugging seat 41 to cut off the main pipe 11, so that the treated water needs to pass through the water quality monitoring probe during transportation, further improving the detection accuracy of the water quality monitoring probe.

[0064] It should be noted that when the movable partition 34 and the fixed partition 33 are in a state of cooperating to cut off the branch pipe 12, the plugging cover 42 is not in contact with the plugging seat 41, so that the water flow can be directly transported backward from the main pipe 11 through the gap between the plugging cover 42 and the plugging seat 41, thereby achieving the purpose of non-stop water delivery when the water quality monitoring probe is cleaned.

[0065] In one embodiment, the reagent cleaning mechanism 2 includes two medicine storage boxes 21 for storing cleaning reagents and pure water respectively, and a liquid delivery assembly 22 connecting the medicine storage boxes 21 and the branch pipe 12;

[0066] A liquid storage cavity is provided in the medicine storage box 21, and a piston plate is provided in the liquid storage cavity which can move up and down and abuts against the inner wall of the medicine storage box 21. The piston plate divides the liquid storage cavity into two upper and lower chambers, and the cleaning agent and pure water are stored in the upper chamber. The upper and lower chambers are both connected to the liquid delivery and drainage assembly 22, and two valves are provided on the medicine storage box 21, which are respectively connected to the upper and lower chambers;

[0067] The infusion and drainage assembly 22 includes a plurality of infusion tubes connecting the upper and lower chambers of the medicine storage box 21 and the branch pipe 12, a drainage tube connecting the branch pipe 12, and a switching valve for controlling the connection status of the infusion tubes corresponding to different medicine storage boxes 21. The infusion tube corresponding to the upper chamber is connected to the area above the movable partition 34 of the branch pipe 12, the infusion tube corresponding to the lower chamber is connected to the area below the movable partition 34 of the branch pipe 12, and the drainage tube is connected to the area above the movable partition 34 of the branch pipe 12. When the movable partition 34 cuts off the branch pipe 12, treated water can be used to inject the medicine storage box 21 along the infusion tube corresponding to the lower chamber, so as to push the liquid stored in the upper chamber into the branch pipe 12 along the infusion tube corresponding to the upper chamber, and then be discharged from the branch pipe 12 through the drainage tube.

[0068] This design enables the liquid delivery component 22 to deliver treated water to the lower part of the piston plate, use the water pressure of the treated water itself to push the piston plate upward, and squeeze the upper agent into the area where the water quality monitoring probe is located, thereby achieving the delivery of the agent without the need for a water pump, effectively reducing costs.

[0069] During specific implementation, the liquid delivery and drainage assembly 22 includes a valve body, a valve core that can move up and down and is disposed in the valve body, and a telescopic component that drives the valve core to move up and down. The valve body and the branch pipe 12 are connected with pipes ②, ④ and ⑦ in sequence from top to bottom, wherein one end of pipe ② connected to the valve body is located above the protective cover, one end of pipe ④ connected to the valve body is located above the fixed partition 33, and one end of pipe ⑦ connected to the valve body is located below the fixed partition 33. On the other side of the valve body, pipes ①, ③, ⑤, ⑥ and ⑧ are disposed in sequence from top to bottom, wherein pipes ① and ⑥ are connected to the medicine storage box 21 corresponding to pure water, and are located on the upper and lower sides of the piston plate, respectively, pipes ③ and ⑧ are connected to the medicine storage box 21 corresponding to the cleaning agent, and are located on the upper and lower sides of the piston plate, respectively, and pipe ⑤ is connected to the wastewater storage tank;

[0070] When the reagent cleaning mechanism 2 is not working, the pipes ②, ④ and ⑦ are all blocked by the valve core, and the medicine storage box 21 and the water quality monitoring pipeline 1 do not interfere with each other;

[0071] When the reagent cleaning mechanism 2 is working, the valve core moves down to Figure 5 In the state shown, pipe ① is connected to pipe ②, pipe ⑥ is connected to pipe ⑦, and pipe ⑤ is connected to pipe ④, so that the medicine storage box 21 corresponding to the pure water is pushed by the treated water pressure, and the internal pure water is squeezed into the water quality monitoring probe, and the water quality monitoring probe is pre-cleaned, and the cleaning waste water is discharged through pipe ⑤. After that, the valve core moves up to the position shown in FIG. Figure 6 In the state shown, pipe ③ is connected to pipe ②, pipe ⑦ is connected to pipe ⑧, and pipe ⑤ is connected to pipe ④, so that the medicine storage box 21 corresponding to the cleaning agent is pushed by the treated water pressure, squeezing the internal cleaning agent into the water quality monitoring probe to clean the water quality monitoring probe, and the cleaning waste water is discharged through pipe ⑤. After a period of time, the valve core is switched to Figure 5 In the state shown, pure water is used to flush away the residual cleaning agent from the water quality monitoring probe, and the cleaning waste water is discharged through pipe ⑤. Finally, the valve core can be moved to Figure 4 The status shown is OK.

[0072] It should be noted that the medicine and treated water in the medicine storage box 21 are replenished and discharged through a valve at regular intervals.

[0073] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0074] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0075] In addition, "plurality" means two or more.
