Description

Technical Field

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the acceleration of urbanization and the continuous growth of population, water shortage and water pollution problems are becoming increasingly serious. Traditional water supply systems often use a single water source, which makes it difficult to meet the different water quality needs of different users.

However, since the existing differentiated water supply system is equipped with a large number of water quality monitoring sensors to monitor the quality of the filtered water to ensure that the water quality meets the standards, the water quality monitoring sensors need to be cleaned and maintained regularly to maintain accuracy. Currently, the water quality monitoring sensors need to be removed from the differentiated water supply system during cleaning, which not only causes the water supply of the differentiated water supply system to be interrupted, but also because the water quality monitoring sensors are distributed in various places, there are also problems of long cleaning time and low efficiency.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not 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 of 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 water supply system with differentiated qualities and a monitoring probe that can be maintained without stopping the system or disassembling the monitoring probe, comprising:

[0040] The filtration system consists of multiple filtration devices, which are connected in stages to perform graded filtration treatment on the raw water;

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

[0042] Water quality monitoring system, which consists of multiple water quality monitoring probes, which are respectively set at the water outlet of multiple filtering devices to monitor the water quality parameters of the treated water output by each filtering device;

[0043] A cleaning system is 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 cleaning agents and pure water, and discharge the water mixed with the cleaning agents 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 probes in the original quality-separated water supply system, so that when the water quality monitoring probes need cleaning and maintenance, they can be separated from the water quality monitoring system by the cleaning system, so that the area where the water quality monitoring probes are located is called a cleaning area independent of the water quality monitoring system. This 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-separated 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 long waiting time caused by re-filtration when needed, and can also provide a certain redundancy for the quality-based 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 connected to 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] Multiple chemical cleaning mechanisms 2, used to connect to the corresponding water quality monitoring pipes 1, transport cleaning chemicals and pure water into the corresponding water quality monitoring pipes 1, and clean the water quality monitoring probes;

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

[0053] With this 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. After that, the chemical cleaning mechanism 2 can be used to supply different cleaning agents to the water quality monitoring probe 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. The main pipe 11 is provided with a branch pipe 12 connected to the main pipe 11 and for installing a water quality monitoring probe. A return pipe 13 is further provided between the branch pipe 12 and the main pipe 11 for returning water in the branch pipe 12 to the main pipe 11. 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 provided 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] This design, by installing the water quality monitoring probe at the end of the branch pipe 12, can improve the convenience of disassembling and maintaining the water quality monitoring probe. 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 isolating mechanism 3 includes a rotating shaft 31 rotatably disposed within the branch pipe 12. The rotating shaft 31 is provided with an arc-shaped plate 32 that 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 isolating 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 drive assembly for driving the rotation shaft 31 to rotate is provided 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 curved 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 curved 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 rotary 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 sealing seat 41 arranged in the main pipe 11 and located between the branch pipe 12 and the return pipe 13. The sealing 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 blocking cover 42 to cooperate with the blocking 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 blocking cover 42 does not contact the blocking seat 41, so that the water flow can be directly transported backward from the main pipe 11 through the gap between the blocking cover 42 and the blocking seat 41, thereby achieving the purpose of non-stop water supply when cleaning the water quality monitoring probe.

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

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

[0067] The infusion and drainage assembly 22 includes multiple 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 that controls 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. It is used to enable treated water to be injected into the medicine storage box 21 along the infusion tube corresponding to the lower chamber when the movable partition 34 cuts off the branch pipe 12, and push the liquid stored in the upper chamber to be injected into the branch pipe 12 along the infusion tube corresponding to the upper chamber, and 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 up, 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 assembly 22 includes a valve body, a valve core that can move up and down and is arranged 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 the end of pipe ② connected to the valve body is located above the protective cover, the end of pipe ④ connected to the valve body is located above the fixed partition 33, and the 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 arranged 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 respectively located on the upper and lower sides of the piston plate, pipes ③ and ⑧ are connected to the medicine storage box 21 corresponding to the cleaning agent, and are respectively located on the upper and lower sides of the piston plate, and pipe ⑤ is connected to the wastewater storage tank;

[0070] When the chemical cleaning mechanism 2 is not working, pipes ②, ④ and ⑦ are all blocked by the valve core, and the chemical 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, squeezing the internal pure water into the water quality monitoring probe, pre-cleaning the water quality monitoring probe, and the cleaning waste water is discharged through pipe ⑤. After that, the valve core moves up to 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 storage tank 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 switches 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 the ⑤ pipe. 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 the 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 various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications 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 for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can 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.
