[0002] In recent years, with the continuous advancement of urbanization, rapid industrial development, increasing sewage discharge, and faster population migration, the urban water resource load has increased. In addition, most urban water bodies are closed shallow water bodies with static or poor mobility, which have the characteristics of small water environment capacity, weak water self-purification ability, and easy pollution, which brings huge challenges to urban water environment management. With the continuous development of digital technology and information technology, the construction of water environment information system has provided efficient technical support for urban water environment management, and improved the efficiency of urban water environment management to a certain extent.

[0003] The core of digital twin is to build a simulation model to achieve seamless integration and real-time mapping of information space and physical space, so as to manage the physical space objects throughout their life cycle, reduce the uncertainty of complex system predictions and avoid the risks brought by emergency events. At present, in order to meet the digital twin technology of water environment management, the "A Water Affairs Digital Management and Control Equipment" with the publication number of CN219657623U discloses a device that can perform real-time monitoring on the water surface, which has a buoy, and when the push plate moves downward, it drives the monitoring probe to go down to the deeper part of the pool to monitor the water quality.

[0004] However, since most urban water bodies are static or closed shallow water bodies with poor fluidity, the monitoring probes are easily wrapped by solid debris such as sludge, aquatic plants, and garbage during use, resulting in inaccurate detection data. In order to overcome the above technical problems, it is urgent to improve the existing technology. Utility Model Content

[0005] The utility model aims to provide a water quality monitoring device for digital twin technology to solve the technical problem of inaccurate detection data caused by probe contamination.

[0006] According to a first aspect of the present invention, a water quality monitoring device for digital twin technology includes:

[0007] A control box, which is provided with a microprocessor, a data storage, a wireless communication module and a water quality detection module, wherein the water quality detection module, the microprocessor and the data storage together constitute a detection circuit, and the wireless communication module, the microprocessor and the data storage together constitute a communication circuit; the water quality detection module comprises a driving device, an outer sleeve, an inner sleeve and a telescopic rod, wherein the inner sleeve is threadedly connected inside the outer sleeve, the driving device drives the outer sleeve to rotate, the inner sleeve is connected to the control box through the telescopic rod, the inner side wall of the inner sleeve is connected to a water quality sensor, and a guide hole is provided at the bottom of the inner sleeve;

After receiving the radio signal, the wireless communication module of the control box processes the signal and feeds it back to the microprocessor. Subsequently, the microprocessor issues a control instruction to enable the drive device to drive the outer sleeve to rotate. Since the telescopic rod limits the inner sleeve, Rotational freedom, so the inner sleeve moves toward the direction of the water body under the rotation of the outer sleeve, so that the water quality sensor is placed in the water body to be monitored. In this process, since the utility model is provided with a filter cartridge and the moving path of the inner sleeve passes through the interior of the filter cartridge, the filter cartridge can isolate solid debris in the water body outside the filter screen, thereby avoiding contact between the water quality sensor and the solid debris to ensure the accuracy of the water quality detection result; in addition, since the filter cartridge is fixedly connected to the outer sleeve, whenever the inner sleeve moves in the up and down directions, the filter cartridge can rotate with the outer sleeve, thereby shaking and cleaning the solid debris adhering to the filter screen to prevent the filter screen from being blocked. The microprocessor sets up a digital twin model, and through model training, establishes a mapping relationship between actual water quality parameters and digital twin model parameters, processes and analyzes the collected real-time water quality monitoring data in real time, and predicts the water quality change trend and the impact range of pollution sources in the future, so as to realize real-time monitoring of the water quality status of the water area and provide a scientific basis for precise decision-making in water environment management. The data storage device provides a safe storage environment for the collected water quality monitoring data, protects the water quality monitoring data from external environmental factors (such as temperature changes, humidity, vibration and electromagnetic interference, etc.), and also has the function of data backup, and can transmit the collected water quality monitoring data to the data center through the wireless communication module.

[0011] According to some embodiments of the present invention, in order to avoid friction between the inner sleeve and the filter cartridge, a gap is provided between the inner wall of the filter cartridge and the outer wall of the inner sleeve.

[0012] According to some embodiments of the utility model, the filter screen has a plurality of filter holes, and a plurality of brushes are provided on the outer side wall of the lower bottom of the inner sleeve, and the moving path of any of the brushes passes through at least one of the filter holes. When the inner sleeve moves downward, its brush can contact the rotating filter screen to further clean the solid debris adhering to the filter holes.

[0013] According to some embodiments of the present invention, in order to facilitate the cleaning of solid debris adhering to the filter holes, all the filter holes are arranged to be inclined upward from the outside of the filter cartridge to the inside thereof.

[0014] According to some embodiments of the utility model, the telescopic rod has at least two joint tubes, and any two adjacent joint tubes are limited in rotational freedom, thereby limiting the rotational freedom of the inner sleeve relative to the control box.

[0015] According to some embodiments of the utility model, all the joint pipes have a polygonal structure to meet the technical requirements of anti-rotation.

[0016] According to some embodiments of the present invention, in order to reduce signal interference, the wireless communication module is disposed on the outer side of the control box.

[0017] According to some embodiments of the present invention, the water quality monitoring device further comprises a propeller, and the propeller is disposed on the floating block.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] like Figure 1 and Figure 2As shown, according to an embodiment of the first aspect of the utility model, a water quality monitoring device for digital twin technology includes a control box 100 and a float 200, wherein the float 200 is connected to the bottom of the control box 100, and the float 200 can be selected as a low-density plastic part and has a cavity. At this time, the overall density of the float 200 is much lower than the density of water, so that the control box 100 can float on the water surface through the float 200.

[0031] Specifically, the top surface of the control box 100 is provided with a photovoltaic panel 300, one side of the control box 100 is provided with a shooting device 400, and the other side of the control box 100 is provided with a wireless communication module 500. In this embodiment, the shooting device 400 can be a high-definition camera, and the wireless communication module 500 can be a GPRS wireless communication module 500. The control box 100 is provided with a microprocessor 110, a data storage 120, a water quality detection module 600 and a battery 130. The battery 130 can be a lithium battery, which provides power for all electrical components. The photovoltaic panel 300 converts solar energy into electrical energy to supplement the battery 130. The utility model requires strict sealing treatment of electrical components to prevent them from short circuiting when exposed to water. The water quality detection module 600, the shooting device 400, the microprocessor 110 and the data storage 120 together construct a detection circuit, and the wireless communication module 500, the microprocessor 110 and the data storage 120 together construct a communication circuit. The detection circuit and the communication circuit are interconnected to meet the working path of wireless control - hydrological monitoring - data storage - wireless transmission.

[0032] It can be understood that the camera 400 is the basis of video flow measurement, which is used to capture images of the surface of the water body. The camera 400 stores the clear video image data it captures in the data storage 120 and transmits the data to the data center through the wireless communication module 500. The water quality detection module 600 obtains the five water quality constants (temperature, pH value, conductivity, turbidity and dissolved oxygen of the water body) by detecting the water body. The water quality detection module 600 stores its water quality monitoring data in the data storage 120 and transmits the data to the data center through the wireless communication module 500. The microprocessor 110 sets a digital twin model, establishes a mapping relationship between actual water quality parameters and digital twin model parameters through model training, processes and analyzes the collected real-time water quality monitoring data in real time, and predicts the trend of water quality changes and the scope of pollution sources in the future, so as to achieve real-time monitoring of water quality conditions in the water area and provide a scientific basis for the precise decision-making of water environment management; and the microprocessor 110 can extract the video monitoring area image through digital twin technology, combine vectors and matching feature point data, and calculate the water area flow rate, hydrological characteristics and other data. The data storage 120 provides a safe storage environment for all detection data, protects the detection data from external environmental factors (such as temperature changes, humidity, vibration and electromagnetic interference, etc.), and also has the function of data backup, and can transmit valuable data to the data center through the wireless communication module 500.

[0033] like Figure 2 and Figure 3As shown, in order to solve the technical problem of inaccurate detection data caused by probe contamination, the floating block 200 is rotatably connected with a filter cartridge 700, and a sealing structure is provided at the connection between the filter cartridge 700 and the floating block 200. The filter cartridge 700 is provided with a filter screen 710 below the floating block 200, and the filter screen 710 has a plurality of filter holes 711 that can filter solid debris. At the same time, the water quality detection module 600 includes a driving device 610, an outer sleeve 620, an inner sleeve 630 and a telescopic rod 640, and the inner sleeve 630 is threadedly connected to the outer sleeve 620. The driving device 610 can be a motor, and its main shaft 611 is connected to a rotating plate 612, and the rotating plate 612 is fixedly connected to the outer sleeve 620, so that the driving device 610 can drive the outer sleeve 620 to rotate. The inner sleeve 630 is connected to the control box 100 through the telescopic rod 640. The telescopic rod 640 has at least two joint tubes 641. In this embodiment, the number of the joint tubes 641 is three, and each joint tube 641 has a polygonal structure, such as a rectangle, so that any two adjacent joint tubes 641 are limited in rotational freedom, thereby limiting the rotational freedom of the inner sleeve 630 relative to the control box 100. The inner side wall of the inner sleeve 630 is connected with a water quality sensor 650. The bottom of the inner sleeve 630 is provided with a guide hole 631, and water enters and exits the inner sleeve 630 from the guide hole 631. The water quality sensor 650 can use a conventional detection sensor, which can detect the water quality of the water body in contact with it to obtain the five water quality constants. However, when a sudden water pollution incident occurs or a certain water pollutant is monitored, if it is necessary to obtain water quality index parameters other than the five water quality constants, it is necessary to deploy a water quality monitoring device with a special water quality sensor 650 to meet the monitoring of different water quality index parameters.

[0034] In addition, the filter cartridge 700 is fixedly connected to the bottom of the outer sleeve 620, so that when the driving device 610 drives the outer sleeve 620 to rotate, the filter cartridge 700 also rotates together. In addition, since the inner sleeve 630 is threadedly connected to the outer sleeve 620, the moving path of the inner sleeve 630 naturally passes through the inside of the filter cartridge 700, that is, the inner sleeve 630 can move to the filter screen 710 of the filter cartridge 700. It can be understood that in order to avoid friction between the inner sleeve 630 and the filter cartridge 700, there is a gap between the inner side wall of the filter cartridge 700 and the outer side wall of the inner sleeve 630, that is, the inner size of the filter cartridge 700 is larger than the outer size of the inner sleeve 630.

[0035] With the above structure, the utility model floats on the water body through the floating block 200. At this time, the control box 100 is located above the water surface, and the filter screen 710 is located below the water surface. When the water quality needs to be monitored, the data center sends a radio signal to the regional base station, and the regional base station then sends the radio signal to the corresponding water quality monitoring equipment to remotely control the water quality monitoring equipment. After receiving the radio signal, the wireless communication module 500 of the control box 100 processes the signal and feeds it back to the microprocessor 110. Then the microprocessor 110 issues a control instruction to enable the drive device 610 to drive the water quality monitoring equipment. The outer sleeve 620 rotates, and since the telescopic rod 640 limits the rotational freedom of the inner sleeve 630, the inner sleeve 630 moves toward the water body under the rotation of the outer sleeve 620, thereby placing the water quality sensor 650 in the water body to be monitored. In this process, since the utility model is provided with a filter cartridge 700, and the moving path of the inner sleeve 630 passes through the interior of the filter cartridge 700, the filter cartridge 700 can isolate solid debris in the water body outside the filter screen 710, thereby avoiding contact between the water quality sensor 650 and the solid debris, so as to ensure the accuracy of the water quality detection results. In addition, since the filter cartridge 700 is fixedly connected to the outer sleeve 620, whenever the inner sleeve 630 moves in the up and down directions, the filter cartridge 700 can rotate along with the outer sleeve 620, thereby shaking off and cleaning the solid debris adhering to the filter screen 710 to prevent the filter screen 710 from being blocked, so that the water in the filter cartridge 700 maintains stable convection with the external water source, preventing the water in the filter cartridge 700 from becoming stagnant water.

[0036] In some embodiments of the present invention, since there is a gap between the inner side wall of the filter cartridge 700 and the outer side wall of the inner sleeve 630, a plurality of brushes 632 are provided on the lower bottom outer side wall of the inner sleeve 630, and each brush 632 can abut against the inner side wall of the filter cartridge 700, and the moving path of any brush 632 passes through at least one filter hole 711. When the inner sleeve 630 moves downward, its brush 632 can contact the rotating filter screen 710, and although solid debris is adhered to the outer side wall of the filter screen 710, the abutment of the brush 632 cuts off the possibility of solid debris entering from the outside to the inside, and when the brush 632 contacts the filter screen 710, the filter screen 710 will vibrate to further clean the solid debris adhered to the filter hole 711.

[0037] In some embodiments of the present invention, in order to facilitate the cleaning of solid debris adhering to the filter holes 711, all the filter holes 711 are arranged to be inclined upward from the outside to the inside of the filter cartridge 700. When the filter cartridge 700 starts to rotate, due to the arrangement of the filter holes 711, the solid debris adhering to the filter holes 711 has a tendency to diffuse outward, which is conducive to the cleaning of the solid debris.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments of the utility model, the water quality monitoring device further includes a propeller 800. In this embodiment, the number of the propellers 800 is two, and the two propellers 800 are both arranged on the floating block 200 and are arranged in a straight line. The propeller 800 can be a paddle driven by a motor, and the two propellers 800 can work independently of each other to achieve turning on the water surface. The water quality monitoring device can move autonomously on the water surface through the propeller 800 to monitor different monitoring points or perform emergency avoidance.

[0039] Of course, in addition to being able to perform long-distance control through a data center and a regional base station, the present invention can also perform short-distance control through a handheld controller, and is not limited to the above embodiments.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
