Description

Technical Field

[0001] This invention relates to the field of water quality testing equipment technology, specifically to a water supply network pollution detection device and its detection system. Background Technology

[0002] Real-time, continuous, and reliable monitoring of water quality in water supply networks is crucial for ensuring water supply safety. Currently, common online water quality monitoring devices typically expose water quality sensors directly or through simple filtration structures to the water flowing through the network to measure parameters such as pH, turbidity, and residual chlorine. However, in actual long-term operation, these devices have revealed several inherent defects caused by limitations in their structural design.

[0003] First, most devices only use simple filters or sedimentation chambers to pretreat water samples. Their structure has limited effectiveness in retaining fine particles, colloidal substances, and microbial films. The sensor probe or optical window is in direct contact with the water flow containing impurities for a long time, which can easily cause pollutants to adhere, accumulate, or even physically block the water. This not only leads to a decrease in sensor sensitivity and distortion of measurement data, but also requires the equipment to be frequently shut down for manual cleaning or sensor replacement, resulting in high maintenance costs and difficulty in guaranteeing reliability.

[0004] Secondly, some devices design pretreatment modules such as sedimentation and filtration as separate independent units from sensing and detection modules, connected by complex pipelines. This structure not only increases the overall volume and internal flow resistance of the device, but also makes it easier for pollutants to accumulate in dead corners of the connecting pipelines and cavities, becoming a source of secondary pollution and reducing the pretreatment effect. At the same time, the modular separation structure also makes maintenance and operation cumbersome. Summary of the Invention

[0005] The purpose of this invention is to provide a water supply network pollution detection device and its detection system that combines rapid response and accurate analysis capabilities through the series and coordinated operation of cyclone separation, filtration, online detection by multiple sensors and offline verification. This enables all-weather, multi-level, automated monitoring and early warning of water quality in the network, achieving the effect of timely detection of pollution hazards and ensuring water supply safety, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, a water supply network pollution detection device is provided, including an online water quality detection component installed on the water supply network. The online water quality detection component includes a main shell and an early warning monitoring component and a water quality detection component connected thereto. Inside the main shell, a control component, a detection component, a cyclone separator, and a valve are arranged sequentially from top to bottom. A main inlet pipe connected to the cyclone separator is provided on the outside of the main shell.

[0007] In one possible implementation, the cyclone separator includes an inverted cone-shaped settling chamber, at least one spiral-shaped guide vane on the inner wall of the settling chamber, a useful guide cylinder extending upward at the top of the settling chamber, a ball valve connected to the bottom of the settling chamber via a flange, and an outlet at the upper end of the settling chamber.

[0008] In one possible implementation, a filter cartridge is connected to the top of the flow guide tube via a flange. The filter cartridge includes a mesh-like filter cartridge shell and an ultrafiltration membrane nested inside it. The radius of the filter cartridge is smaller than the radius of the flow guide tube.

[0009] In one possible implementation, a detection component is fitted on the outside of the filter cartridge, and a water-proof pad is provided at the bottom of the detection component. The detection component includes a detection sleeve, the inner side plate of the detection sleeve is mesh-like, and multiple mounting holes communicating with the inside and outside are arranged in a ring at the top of the detection component, which are respectively equipped with a pH sensor, a residual chlorine sensor, a conductivity sensor and a dissolved oxygen sensor.

[0010] In one possible implementation, a ball valve is provided on the main inlet pipe, which extends into the main body housing and is connected to the cyclone separator and the early warning monitoring component via a three-way valve; the detection component is connected to the water quality detection component via a pipe and a ball valve is installed on the pipe.

[0011] In one possible implementation, the early warning monitoring component includes a protective housing and an early warning monitoring cavity disposed therein. The early warning monitoring cavity is provided with an inlet and an outlet that communicate with the outside through the protective housing. A turbidity sensor is provided at the top of the early warning monitoring cavity, and a drain outlet and ball valve are provided at the bottom of the early warning monitoring cavity.

[0012] In one possible implementation, the control component includes a waterproof housing and a circuit board disposed therein, and also includes a battery connected to the circuit board. The output and input terminals of the circuit board are respectively connected to an early warning monitoring component, a detection component, and a water quality detection component.

[0013] In one possible implementation, the water quality testing assembly includes a hinged water quality testing housing and a door panel, with a reagent kit and a testing sensor housed inside the water quality testing housing.

[0014] In one possible implementation, the top of the main body casing is provided with a solar panel connected to the battery, and also includes a signal antenna provided at the top of the main body casing and connected to a circuit board.

[0015] A detection system for a water supply network pollution detection device includes a water supply network pollution detection device, a data transmission unit, and a background monitoring terminal. The data transmission unit is communicatively connected to the control component of the detection device and the background monitoring terminal. The early warning monitoring component of the detection device has a built-in turbidity sensor, and the water quality detection component has built-in total chlorine sensor, OPR sensor, conductivity sensor, and temperature sensor. The detection component also has built-in pH sensor, residual chlorine sensor, conductivity sensor, and dissolved oxygen sensor, all of which are connected to the control component. The control component receives and preprocesses the water quality parameter data collected by each sensor and sends the data to the background monitoring terminal through the data transmission unit. The background monitoring terminal has a built-in water pollution threshold database and receives the preprocessed water quality parameter data, compares it with preset thresholds, and generates a water pollution judgment result.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a parallel early warning monitoring component and a depth detection path including a cyclone separator and a filter cartridge on the main water inlet path, the device can perform rapid screening and accurate analysis simultaneously. The early warning monitoring component is dedicated to turbidity detection. Utilizing the characteristic that turbidity is sensitive to pollution events, the device can detect abnormal turbidity of the water body with almost no delay, thus achieving early warning.

[0017] 2. By employing a multi-stage pretreatment unit consisting of a hydrocyclone separator and an ultrafiltration membrane filter cartridge, the water sample entering the depth detection path is purified step by step. The hydrocyclone separator uses centrifugal force to efficiently remove particulate impurities with a higher specific gravity, while the filter cartridge further traps fine suspended solids and biofilm debris, resulting in high cleanliness of the water sample entering the subsequent sensor detection chamber. This makes it less likely for precision detection components such as pH sensors, residual chlorine sensors, conductivity sensors, and dissolved oxygen sensors to be contaminated or clogged, significantly reducing maintenance frequency and sensor wear, and improving the long-term stability and data reliability of online detection.

[0018] 3. By integrating multi-parameter online sensors into a detection component mounted outside the filter cartridge and connecting it to a water quality detection component capable of reagent-based testing via a controllable pipeline, the device integrates both real-time online monitoring and laboratory-level precise verification capabilities. The control component can automatically determine whether to initiate verification testing based on online monitoring results or preset programs, and integrates and remotely reports all data, making the monitoring results more comprehensive and accurate, enhancing the ability to judge complex water pollution, and realizing the integration and intelligence of monitoring functions.

[0019] 4. By installing control components that integrate data processing, communication, and control logic, and equipping them with solar panels and signal antennas, the device can automatically execute the entire process of sampling, detection, cleaning, sewage discharge, and data transmission and reception, and achieve energy self-sufficiency and remote monitoring. This reduces the need for manual intervention and allows the device to be deployed at pipeline nodes in areas without mains power or in remote areas, enabling continuous monitoring around the clock and without human intervention, thus improving the coverage and operational efficiency of the monitoring network.

[0024] like Figure 1 The device shown is a water supply network pollution detection device, which is applied to municipal water supply, industrial water supply or building water supply network systems. It is used to monitor the water quality of the water supply network in real time, detect potential pollution hazards in a timely manner and issue early warnings to ensure water supply safety.

[0025] In one implementation, such as Figure 1-10 The device for detecting pollution in a water supply network includes an online water quality detection component installed on the water supply network. The online water quality detection component includes a main shell 1 and an early warning monitoring component 7 and a water quality detection component 4 connected thereto. Inside the main shell 1, from top to bottom, there are a control component 6, a detection component 11, a cyclone separator 9 and a valve 5. On the outside of the main shell 1, there is a main water inlet pipe 101 connected to the cyclone separator 9.

[0026] In this embodiment, the main shell 1 serves as the primary support and protective structure, typically made of corrosion-resistant, high-strength metal or engineering plastic. An installation space is formed inside the main shell 1, and a backwash pump connected to the detection component 11 is installed within it. Water from the pipeline enters the hydrocyclone separator 9 via the main inlet pipe 101 and a portion passes through a three-way valve. The hydrocyclone separator 9 uses centrifugal force to separate heavier particulate impurities from the water sample. The pretreated water sample flows sequentially through the detection component 11 for real-time online sensing and detection. It can also be diverted to the water quality detection component 4 for more precise reagent-based detection as needed. Another portion of the water sample enters the early warning monitoring component 7, which performs rapid turbidity screening on the raw water to achieve early warning. The control component 6 coordinates the operation of all components and processes, stores, and transmits data. The entire detection process is highly automated, enabling continuous and real-time monitoring of the pipeline water quality, timely detection of water pollution, and ensuring water supply safety.

[0027] In one possible implementation, the cyclone separator 9 includes an inverted cone-shaped settling chamber 901, at least one spiral-shaped guide vane 902 is provided on the inner wall of the settling chamber 901, a guide tube extends upward at the top of the settling chamber 901, a ball valve 8 is connected to the bottom of the settling chamber 901 through a flange, and the upper end of the settling chamber 901 is a water outlet.

[0028] In this embodiment, the inverted conical structure of the settling chamber 901 is matched with the spiral guide vane 902. That is, the spiral angle of the guide vane 902 is adapted to the cone angle of the settling chamber 901, and the edge of the vane fits seamlessly with the chamber wall without any gaps or dead angles. This allows the water sample to enter from the main inlet pipe 101 and form a stable spiral downward flow under the guidance of the vane. Centrifugal force and gravity work together to act on the impurities, thereby improving the settling efficiency. At the same time, the coaxial connection between the guide tube and the upper outlet of the settling chamber 901 allows the upper clean water sample to be discharged smoothly, avoiding secondary suspension of impurities caused by water flow turbulence. The bottom ball valve 8 is connected to the flange of the settling chamber 901 to ensure the sealing during sewage discharge. The water flow impact force when the ball valve 8 is opened can wash away residual impurities on the chamber wall, thereby extending the maintenance cycle of the hydrocyclone separator 9.

[0029] The working principle is as follows: the water sample to be tested enters the upper part of the settling chamber 901 tangentially through the main inlet pipe 101. Under the guidance of the guide vanes 902, a strong vortex is formed. Under the action of centrifugal force, suspended particles with a density greater than that of water are thrown towards the chamber wall and rotate downward along the cone wall to settle, eventually accumulating near the drain outlet at the bottom. The lighter clean water forms a low-pressure vortex towards the center and moves upward, and is discharged through the outlet at the top of the guide tube. This effectively removes large particles in the water sample that may clog the sensor or interfere with the detection results, extends the service life of the precision detection components, and improves the detection accuracy.

[0030] In one possible implementation, a filter cylinder 10 is connected to the top of the flow guide tube via a flange. The filter cylinder 10 includes a mesh-like filter cylinder shell and an ultrafiltration membrane nested inside it. The radius of the filter cylinder 10 is smaller than the radius of the flow guide tube.

[0031] In this embodiment, the mesh-like filter cartridge shell and the internal ultrafiltration membrane form a double-layer filtration system. The mesh of the shell serves to initially intercept large particulate impurities and protect the ultrafiltration membrane. The ultrafiltration membrane is mainly used to intercept biofilm debris, thereby reducing interference and damage to the sensor. The radius of the filter cartridge 10 is smaller than that of the guide tube. It is connected to the hydrocyclone separator 9 through the curved guide tube to ensure that the water flow smoothly transitions from the guide tube to the filter cartridge 10. The working principle is as follows: After the clean water separated by the hydrocyclone flows out of the guide tube, it enters the filter cartridge 10. The water first passes through the outer mesh-like shell to remove any possible residual fine particles, and then passes through the ultrafiltration membrane to filter the biofilm debris. This greatly reduces the contamination of the optical sensor window by suspended solids and the adhesion of the electrochemical sensor electrodes, ensuring the long-term stable operation of various sensors and the reliability of the detection data.

[0032] In one possible implementation, a detection component 11 is sleeved on the outside of the filter cartridge 10, and a water-proof pad is provided at the bottom of the detection component 11. The detection component 11 includes a detection sleeve, the inner side plate of the detection sleeve is mesh-shaped, and multiple mounting holes communicating with the inside and outside are provided at the top of the detection component 11 and arranged in a ring. A pH sensor 12, a residual chlorine sensor 13, a conductivity sensor 14 and a dissolved oxygen sensor 15 are respectively provided.

[0033] In this embodiment, the detection component 11 is sleeved on the outside of the filter cylinder 10. The mesh of its inner side plate and the mesh of the filter cylinder shell form a permeable channel, allowing the filtered water sample to diffuse evenly into the inside of the detection sleeve. The annular mounting holes at the top of the detection component 11 are equipped with water quality sensors, which are evenly distributed around the circumference. The sensor probes pass through the mounting holes and extend into the inside of the detection component 11 to contact the water sample in the detection chamber, thereby measuring the corresponding water quality parameters in real time. The water-proof pad is made of elastic sealing material and is used to isolate the cyclone separator 9 from the detection component 11, preventing unfiltered water from short-circuiting into the detection area. The working principle is that after the clean water sample passes through the ultrafiltration membrane from the inside of the filter cylinder 10, it is detected by the sensors installed on the top of the detection component 11. The pH sensor 12 is used to detect the acidity and alkalinity of the water sample, the residual chlorine sensor 13 is used to detect the amount of disinfectant residue, the conductivity sensor 14 is used to assess the total dissolved solids content in the water, and the dissolved oxygen sensor 15 is used to reflect the redox state and microbial activity potential of the water body, which can comprehensively reflect the basic chemical and sanitary conditions of the pipe network water.

[0034] In one possible implementation, the main water inlet pipe 101 is equipped with a ball valve 8. After the main water inlet pipe 101 extends into the main body shell 1, it is connected to the cyclone separator 9 and the early warning monitoring component 7 respectively through a three-way valve. The detection component 11 is connected to the water quality detection component 4 through a pipe and a ball valve 8 is installed on the pipe.

[0035] In this embodiment, the three-way valve enables selective connection between the main inlet pipe 101 and the cyclone separator 9 and the early warning monitoring component 7. In this way, the inlet water is divided into two paths: one path enters the cyclone separator 9 for pretreatment and in-depth detection, and the other path directly enters the early warning monitoring component 7 for rapid screening. The detection component 11 is connected to the water quality detection component 4 through a pipeline, and a ball valve 8 is installed on the pipeline. The ball valve 8 is used to control whether to send a portion of the water sample after online detection to the water quality detection component 4 for laboratory-level verification detection. This allows the device to have both rapid online monitoring and accurate offline verification capabilities, improving the integrity and reliability of the detection system.

[0036] In one possible implementation, the early warning monitoring component 7 includes a protective housing 701 and an early warning monitoring cavity 702 disposed therein. The early warning monitoring cavity 702 is provided with an inlet 705 and an outlet 704 that pass through the protective housing 701 and communicate with the outside. A turbidity sensor 703 is provided at the top of the early warning monitoring cavity 702, and a drain outlet and a ball valve 8 are provided at the bottom of the early warning monitoring cavity 702.

[0037] In this embodiment, turbidity is a highly sensitive indicator of sudden water pollution, especially particulate matter pollution, biological pollution, or chemical precipitation pollution. The turbidity sensor 703 is installed at the top of the early warning monitoring chamber 702, directly opposite the inlet 705. After the water sample enters, it can directly contact the sensor probe. The early warning monitoring chamber 702 is cylindrical in shape, forming a smooth flow channel with the inlet 705 and outlet 704 to prevent water sample stagnation. The ball valve 8 at the bottom drain outlet can periodically discharge impurities from the early warning monitoring chamber 702 to prevent contamination of the sensor probe. Inside the protective housing 701, for easy turbidity detection... The early warning monitoring chamber 702 has an observation window on one side and is equipped with a transparent baffle. An LED light source is installed inside the protective housing 701 to provide stable and uniform backlight or sidelight illumination for observation and turbidity measurement. The working principle is that by diverting raw water into the early warning monitoring chamber 702 and directly measuring its turbidity through the turbidity sensor 703, abnormal turbidity phenomena in the pipeline network can be detected with almost no delay. If the turbidity sensor 703 detects a value exceeding the preset threshold, the control component 6 can immediately issue an alarm signal to prompt the staff to intervene, thereby achieving early detection and rapid response to pollution events.

[0038] In one possible implementation, the control component 6 includes a waterproof housing 603 and a circuit board 601 disposed therein, and also includes a battery 602 connected to the circuit board 601. The output and input terminals of the circuit board 601 are respectively connected to the early warning monitoring component 7, the detection component 11 and the water quality detection component 4.

[0039] In this embodiment, the control component 6 is responsible for periodically collecting data from all sensors, processing, analyzing, and storing the data; controlling the opening and closing of each ball valve 8 according to program logic to realize automatic sampling, flushing, backflushing, and sewage discharge processes; simultaneously, receiving alarm signals from the early warning monitoring component 7 and activating the linkage mechanism, and sending the data packaged to the remote monitoring center through the wireless communication module; then managing the charging and discharging process of the solar panel 2 to the battery 602 to optimize energy consumption; finally, its embedded software can be configured and programmed according to the specific requirements of different water supply networks.

[0040] In one possible implementation, the water quality testing component 4 includes a hinged water quality testing housing 402 and a door panel 401, with a reagent kit 404 and a testing sensor 403 disposed inside the water quality testing housing 402.

[0041] In this embodiment, the water quality detection component 4 includes a hinged water quality detection housing 402 and a door panel 401. The door panel 401 can be opened for easy internal maintenance and reagent replacement. Secondly, the detection sensor 403 includes sensors for total chlorine, OPR, conductivity, and temperature. The water quality detection housing 402 may also integrate a small precision peristaltic pump, a mixing reaction cell, and an optical detection unit to achieve automatic sample introduction, reagent addition, mixing reaction, and colorimetric / turbidimetric determination, avoiding systematic errors of a single parameter. The working principle is as follows: when the online detection component detects an abnormality in a parameter or requires periodic calibration as planned, the control component 6 can open the ball valve 8 on the connecting pipeline, allowing a portion of pretreated clean water sample to enter the water quality detection component 4. The water quality detection component 4 automatically performs a series of reagent addition, mixing, and reaction operations, and then reads the reaction results through the built-in detection sensor 403, comparing them with the standard in the reagent kit 404 to obtain accurate quantitative or semi-quantitative results.

[0042] In one possible implementation, the top of the main body shell 1 is provided with a solar panel 2 connected to the battery 602, and also includes a signal antenna 3 provided at the top of the main body shell 1 and connected to the circuit board 601.

[0043] In this embodiment, the solar panel 2 converts light energy into electrical energy and charges the battery 602 through the controller, which greatly extends the continuous working time of the device in areas without mains power access and improves deployment flexibility. The signal antenna 3 is used to receive and transmit wireless signals, such as GPRS, 4G, NB-IoT or LoRa signals, and transmits detection data, device status and alarm information to a remote server or cloud platform in real time. At the same time, it can also receive control commands from the monitoring center to realize remote control and configuration, which meets the communication needs of IoT nodes in the smart water system.

[0044] The workflow of the water supply network pollution detection device provided in this embodiment is as follows: Water from the network enters the device through the main inlet pipe 101. One stream is diverted to the early warning monitoring component 7, where it is checked in real time by the turbidity sensor 703. The other main stream enters the cyclone separator 9, where large particles of impurities are removed. The clean water rises and enters the filter cartridge 10 for fine filtration through the guide tube. Part of the filtered clean water sample is detected in real time at the top of the filter cartridge 10 by the pH sensor 12, residual chlorine sensor 13, conductivity sensor 14, and dissolved oxygen sensor 15, and the data is uploaded in real time. Another part of the water sample can be tested more accurately by the reagent method through the water quality detection component 4 according to the instructions. All detection data are collected and processed by the control component 6 and sent to the monitoring center through the signal antenna 3. The control component 6 also controls each ball valve 8 according to the preset program or remote instructions, either periodically or by event triggering, to perform automatic sewage discharge operations of the cyclone separator 9 and the early warning monitoring chamber 702, as well as backwashing operations of the filter cartridge 10, so as to realize the self-maintenance of the device. The solar panel 2 continuously replenishes the system with power to ensure long-term stable operation.

The data transmission unit is communicatively connected to the control component of the detection device and the background monitoring terminal. The early warning monitoring component of the detection device has a built-in turbidity sensor, and the water quality detection component has built-in total chlorine sensor, OPR sensor, conductivity sensor, and temperature sensor. The detection component also has built-in pH sensor 12, residual chlorine sensor, conductivity sensor, and dissolved oxygen sensor, all of which are connected to the control component 6. The control component 6 is used to receive and preprocess the water quality parameter data collected by each sensor, and send the data to the background monitoring terminal through the data transmission unit.
