Detailed Implementation

[0020] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Over time, the water quality may change during the transportation of water through municipal pipe networks. In order to monitor the water quality transported by municipal pipe networks in real time, pipe network water quality monitoring devices are installed on the pipes of municipal pipe networks.

[0022] For sewage transportation in municipal pipe networks, turbidity is a key water quality early warning indicator, directly related to water supply security, pipe network stability, and public health. Typically, water turbidity is obtained through turbidity sensors.

[0023] However, in actual operation, parameters such as water temperature, pH value, conductivity, and residual chlorine need to be considered in conjunction with turbidity to create a comprehensive picture of the water quality in the pipe network.

[0024] In the process of developing this application, the applicant discovered at least the following shortcomings in the relevant technology: Obtaining parameters such as turbidity, temperature, pH, conductivity, and residual chlorine in water typically requires the installation of corresponding sensors, which leads to complex wiring and high costs, leaving room for improvement.

[0025] Based on the above-mentioned technical problems, this application provides a multi-parameter pipeline water quality monitoring device, which integrates a sensor chip for testing temperature, pH value, conductivity and residual chlorine into a monitoring module. This monitoring module is also integrated with a turbidity sensor to form an independent monitoring device, so that the monitoring device can simultaneously monitor the turbidity, temperature, pH value, conductivity and residual chlorine of the water quality, thereby simplifying wiring and reducing costs.

[0026] Based on the above design concept and in conjunction with the accompanying drawings, the details of the setup of the multi-parameter pipeline water quality monitoring device provided in this application are further described below.

[0027] Figure 1 A schematic diagram of the structure of a multi-parameter pipeline water quality monitoring device 10 according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 A schematic diagram of the explosion. Combined with... Figure 1 as well as Figure 2 The multi-parameter pipeline water quality monitoring device 10 provided in this application is used for monitoring the water quality of municipal pipelines 20. The monitoring device includes a monitoring pipeline 100, a turbidity sensor 200, and a monitoring module 300 (combined with...). Figure 5 The monitoring system includes a monitoring pipe 100 with a valve 400, a monitoring chamber 110 built into the monitoring pipe 100, the monitoring pipe 100 extending axially, and a monitoring end 120 and a water supply end 130; a turbidity sensor 200 connected to the monitoring end 120 of the monitoring pipe 100, the monitoring part of the turbidity sensor 200 being disposed within the monitoring chamber 110; a monitoring module 300 integrating at least one sensing chip, the monitoring module 300 being disposed within the monitoring chamber 110 and connected to the turbidity sensor 200; and a valve 400 connected to the water supply end 130 of the monitoring pipe 100 and connected to the municipal pipeline 20.

[0028] The multi-parameter pipeline water quality monitoring device 10 provided in this application has a monitoring chamber 110 built into the monitoring pipeline 100. The valve 400 is connected to the water supply end 130 of the monitoring pipeline 100 and is connected to the municipal pipeline 20. Therefore, when the valve 400 is opened, the water in the municipal pipeline 20 can flow into the monitoring chamber 110 of the monitoring pipeline 100 through the valve 400. Since the turbidity sensor 200 is connected to the monitoring end 120 of the monitoring pipeline 100 and the monitoring part of the turbidity sensor 200 is set in the monitoring chamber 110, the turbidity of the water in the municipal pipeline 20 can be obtained through the turbidity sensor 200. In addition, since the monitoring module 300 integrates at least one sensor chip and is set in the monitoring chamber 110, the other parameters of the water quality in the municipal pipeline 20 can be monitored through the monitoring module 300.

[0029] Combination Figure 1 as well as Figure 2In order to achieve the connection between the monitoring device and the municipal pipeline 20, the monitoring device provided in this application also includes an installation component 500 and a connecting pipe 600. The installation component 500 includes a first pipe body 510 and a second pipe body 520. Both the first pipe body 510 and the second pipe body 520 are arc-shaped and can be spliced ​​together to form a ring structure covering the outer circumference of the municipal pipeline 20. In addition, a water inlet 530 is provided on the circumference of the first pipe body 510. The water inlet 530 is connected to the connecting port 20a opened on the municipal pipeline 20. The connecting pipe 600 connects the water inlet 530 and the valve 400, so that the water of the municipal pipeline 20 can be output to the valve 400 through the connecting pipe 600.

[0030] In some embodiments, both the first pipe body 510 and the second pipe body 520 are semi-circular in shape, adapted to the outer diameter of the municipal pipeline 20. Each of the opposite sides of the first pipe body 510 and the second pipe body 520 is provided with an outwardly extending connecting flange 540. The connecting flanges 540 of the first pipe body 510 and the second pipe body 520 are connected by multiple screws, thereby allowing the mounting component 500 to be fixed to the municipal pipeline 20. Furthermore, by selecting a first pipe body 510 and the second pipe body 520 with appropriate apertures according to the diameter of the municipal pipeline 20, the versatility and applicability of the monitoring device can be improved.

[0031] In some embodiments, the connecting pipe 600 can be integrally formed with the first pipe body 510, or the two can be welded together. One end of the connecting pipe 600 wraps around the water inlet 530, and the other end of the connecting pipe 600 is connected to the valve 400. That is, through the transfer of the connecting pipe 600 and the valve 400, this application can transport water transported by the municipal pipeline 20 to the monitoring pipeline 100, that is, the area that the turbidity sensor 200 and the monitoring module 300 can monitor, and then monitor the relevant parameters of the water quality.

[0032] When installing the turbidity sensor 200 with integrated monitoring module 300 onto valve 400, valve 400 can be controlled to close to avoid installation inconvenience caused by water leakage in municipal pipeline 20. After the turbidity sensor 200 with integrated monitoring module 300 and valve 400 are assembled in place, valve 400 can be opened, allowing water in municipal pipeline 20 to be transported to monitoring pipeline 100 through valve 400. This enables the turbidity sensor 200 and monitoring module 300 to operate, thereby monitoring relevant water quality parameters. This facilitates the assembly of the turbidity sensor 200 with integrated monitoring module 300 and valve 400. For example, valve 400 can be a ball valve with an operating lever for controlling its opening, allowing for quick and easy opening of valve 400.

[0033] In some embodiments, the connecting pipe 600 can be threadedly connected to the inlet 530 of the valve 400, and the inlet end of the monitoring pipe 100 can be threadedly connected to the outlet of the valve 400, to facilitate the connection and assembly of the connecting pipe 600 with the valve 400 and the valve 400 with the monitoring pipe 100. Additionally, sealing rings can be provided between the connecting pipe 600 and the inlet 530 of the valve 400, and between the inlet end of the monitoring pipe 100 and the outlet of the valve 400, to prevent water leakage.

[0034] Figure 3 It shows Figure 1 An assembly diagram of the turbidity sensor 200, which integrates the monitoring module 300, and the monitoring module 300. Figure 4 It shows Figure 3 The cross-sectional structural schematic diagram, combined with Figure 3 as well as Figure 4 In some embodiments, the turbidity sensor 200 includes a first body 210, which is tubular, and a connecting protrusion 220 is provided on the circumferential surface of the first body 210. The monitoring device also includes an assembly pipe 700 and a clamp 800. The monitoring end 120 of the monitoring pipe 100 is connected to the assembly pipe 700. The connecting protrusion 220 on the first body 210 is placed on the end of the assembly pipe 700 away from the monitoring pipe 100. The clamp 800 is connected to the outer circumferential surface of the assembly pipe 700 and the connecting protrusion 220, so that the first body 210 and the monitoring pipe 100 can be assembled together using the clamp 800 and the assembly pipe 700.

[0035] Combination Figure 3 as well as Figure 4 In some embodiments, an annular limiting flange 710 is provided on the inner side of the end of the assembly pipe 700 away from the monitoring pipe 100. The monitoring end 120 of the monitoring pipe 100 is inserted into the assembly pipe 700 with an interference fit or a threaded fit and abuts against the limiting flange 710. An annular supporting flange 720 is provided on the inner side of the end of the assembly pipe 700 away from the monitoring pipe 100. The connecting protrusion 220 on the first body 210 rests on the supporting flange 720. The connecting protrusion 220 and the outer circumference of the supporting flange 720 are on the same circumference, so that the two can be locked together by a clamp.

[0036] Combination Figure 4In some embodiments, a sealing element 900 is further provided between the connecting protrusion 220 and the supporting flange 720 to improve the sealing performance between them and prevent water leakage. For example, the connecting protrusion 220 has a first sealing groove 230 on the side facing the supporting flange 720, and the supporting flange 720 has a second sealing groove 730 on the side facing the connecting protrusion 220. The sealing element 900 is embedded in the first sealing groove 230 and the second sealing groove 730 respectively to ensure the sealing performance between the connecting protrusion 220 and the supporting flange 720. In other configurations, only the first sealing groove 230 or the second sealing groove 730 may be provided. The sealing element 900 is embedded in the first sealing groove 230 and the second sealing groove 730 and protrudes from the surface of the other component to contact the surface of the other component, thus also achieving the sealing performance between the connecting protrusion 220 and the supporting flange 720.

[0037] Figure 5 It shows Figure 1 A schematic diagram of the structure of the turbidity sensor 200 integrating the monitoring module 300 is shown in the figure. Figure 5 In some embodiments, the first body 210 has a first end and a second end. The first end of the first body 210 is disposed within the monitoring cavity 110. The first end of the first body 210 is solid, so that the interior of the first body 210 forms a sealed cavity that can be isolated from water, facilitating the assembly of waterproof components such as the monitoring circuit board and power supply. In addition, the first end of the first body 210 is provided with a step 240, which has a step 240 surface and a transition surface 242. The step 240 surface and the end face of the first end of the first body 210 are connected through the transition surface 242, and the step 240 surface and the transition surface 242 are perpendicular to each other. The turbidity sensor 200 also includes a light emitter 250 and a light receiver 260. The light emitter 250 is mounted on the transition surface 242, and the light receiver 260 is mounted on the step 240 surface. The light emitter 250 and the light receiver 260 are used together to form the aforementioned monitoring unit.

[0038] In this application, the light emitter 250 is mounted on the transition surface 242, and the light receiver 260 is mounted on the step surface 240. This allows the light emitted by the light emitter 250 to be received by the light receiver 260 after a 90° bend. This is a 90° scattering method, which has extremely high sensitivity and is especially suitable for low turbidity measurement. It can also effectively reduce chromaticity interference and has high resistance to particulate matter sedimentation and bubble interference. It is particularly suitable for applications with high precision requirements for low turbidity measurement.

[0039] Combination Figure 5In some embodiments, the turbidity sensor 200 further includes a light-shielding element 270, which is mounted on the surface of the step 240 and located between the light receiver 260 and the transition surface 242. This arrangement maximizes the extraction of the true scattered signal emitted by the light emitter 250 while minimizing interference signals, thereby significantly improving the accuracy and stability of the measurement. Exemplarily, the light-shielding element 270 is a block structure, connected to the surface of the step 240 by screws. The light-shielding element 270 can be made of a rough, dark-colored (e.g., matte black) material to absorb direct light emitted by the light emitter 250 and prevent reflection within the monitoring cavity 110.

[0040] Figure 6 It shows Figure 5 An explosion diagram. Figure 7 It shows Figure 6 The structural diagram of the monitoring module 300 in the middle, combined with Figures 5-7 In some embodiments, the first end face of the first body 210 is provided with an assembly groove 211. The monitoring module 300 includes a second body 310, on which various monitoring chips are integrated. A portion of the second body 310 is adapted to be disposed in the assembly groove 211, and another portion of the second body 310 protrudes from the first end of the first body 210. A fixing protrusion 340 is provided on the peripheral surface of the other portion of the second body 310. The fixing protrusion 340 can be integrally formed with the second body 310, and the fixing protrusion 340 is connected to the end face of the first end of the first body 210, so as to realize the integration of the monitoring module 300 on the turbidity sensor 200. For example, the second body 310 is columnar, with one end fitted into the mounting groove 211 and the other end protruding from the first end of the first body 210, so that the monitoring end 120 of each monitoring chip is also located in the monitoring chamber 110 of the monitoring pipeline. Since water from the municipal pipeline can be transported to the monitoring chamber 110, the relevant parameters of the water quality transported to the monitoring chamber 110 can be monitored by each monitoring chip.

[0041] In some implementations, the monitoring module 300 integrates at least a residual chlorine sensor chip, a pH sensor chip, a conductivity sensor chip, and a temperature sensor chip. This configuration allows the monitoring module 300 to acquire parameters such as residual chlorine, pH, conductivity, and temperature of the water in the municipal water supply network. In specific implementations, the number or type of sensor chips on the monitoring module 300 can be adjusted according to monitoring requirements; this application does not impose any restrictions on this.

[0042] In some embodiments, the monitoring device further includes a monitoring circuit board (not shown), which is disposed within the first body 210 to isolate it from the monitoring cavity 110 and ensure that the monitoring circuit board can work normally. The monitoring circuit board is connected to the light transmitter 250, the light receiver 260 and the monitoring module 300 respectively for processing related data.

[0043] Combination Figure 7 In some embodiments, the second body 310 has a type interface 320 at one end of the mounting groove 211. The monitoring circuit board has connection terminals that are plugged into the type interface 320 to achieve a quick electrical connection and assembly between the monitoring circuit board and the monitoring module 300. In other embodiments, the terminals of the monitoring circuit board can also be directly soldered to the second body 310 to form a permanent connection between the monitoring module 300 and the monitoring circuit board. The specific configuration can be adjusted according to actual needs, and this application will not elaborate on this aspect.

[0044] Similarly, to ensure a tight seal between the second body 310 and the first body 210, a sealing ring (not shown) is provided between the second body 310 and the bottom of the mounting groove 211. Exemplarily, combined with... Figure 7 The second body 310 has multiple coaxial third sealing grooves 330 at one end of the assembly groove 211. The sealing ring and the third sealing groove 330 are set one-to-one. The sealing ring is embedded in the corresponding third sealing groove 330 and contacts the bottom of the groove of the assembly groove 211, thereby ensuring the sealing between the second body 310 and the bottom of the groove of the assembly groove 211. Correspondingly, it also ensures the sealing between the second body 310 and the first body 210.

[0045] In some embodiments, the monitoring device further includes a power supply (not shown), which is disposed within the first body 210 and electrically connected to the monitoring circuit board to serve the normal operation of the monitoring circuit board.

[0046] Combination Figure 3 as well as Figure 4 In some embodiments, the second end of the first body 210 is open to facilitate the assembly of the monitoring circuit board and power supply. Additionally, the turbidity sensor 200 includes a cover 280 connected to the second end of the first body 210 to seal the second end, thereby sealing the interior of the first body 210. Exemplarily, the cover 280 is threadedly connected to the second end of the first body 210 to facilitate the disassembly and assembly of the cover 280 and the first body 210, thereby facilitating the assembly and replacement of the internal components of the first body 210.

[0047] Combination Figure 3 as well as Figure 4In some embodiments, a wiring port 281 is provided at the end of the cover 280 away from the first body 210, through which a cable can be connected to the power supply and / or monitoring circuit board inside the first body 210. This configuration allows for wired data acquisition from the monitoring circuit board and / or charging or powering the power supply. In other embodiments, the data collected by the monitoring circuit board can also be collected to the user terminal wirelessly; this application does not impose any limitations on this method.
