[0002] Urban drainage networks are a crucial component of urban infrastructure, primarily used for collecting, transporting, and treating sewage and rainwater to ensure urban sanitation and residents' quality of life. For example, urban drainage networks can quickly and effectively discharge sewage and rainwater out of urban areas through underground pipe systems. Especially during the rainy season, drainage networks can rapidly divert rainwater, reducing the risk of urban flooding. Furthermore, urban drainage networks can also treat urban sewage to meet standards before discharge, reducing pollution to the natural environment. However, due to the deep burial of urban drainage networks and the complex on-site conditions, various network defects are prone to occur, such as pipe damage and incorrect connections between storm and sewage pipes, which seriously affect the normal and healthy operation of the drainage network.

[0003] Therefore, operation and maintenance personnel often use anti-fouling monitoring devices in drainage pipe networks to monitor the water conditions within the network, such as temperature, to monitor the network's operation. However, due to the large amount of impurities and waste present in urban drainage pipe networks, these substances can easily accumulate on the monitoring devices, affecting their normal operation and negatively impacting the acquisition of water condition monitoring data. Therefore, how to prevent pollutants from accumulating on the anti-fouling monitoring devices in drainage pipe networks has become an urgent technical problem to be solved. Summary of the Invention

[0034] Currently, urban drainage network operation and maintenance personnel often use anti-fouling monitoring devices to monitor changes in the water state within the drainage network, thereby analyzing network defects. However, due to the large amount of impurities or waste present in urban drainage networks, these substances can easily accumulate on the monitoring devices, affecting their normal operation. Therefore, the technical challenge lies in how to prevent contaminants from accumulating on the anti-fouling monitoring devices in drainage networks.

[0035] To at least address the aforementioned issues, this application provides a drainage pipe network anti-fouling monitoring device, which can effectively prevent pollutants from accumulating and ensure the normal operation of the device.

[0036] Please see Figures 1 to 4 As shown, an embodiment of this application provides a drainage pipe network anti-fouling monitoring device, which includes a water monitoring module 1; the water monitoring module 1 includes a guide body 11, a connecting bracket 12 and a water monitoring unit 13; the rear end of the guide body 11 is inverted triangular in shape and connected to the water monitoring unit 13, and the front end is square in cross-section and connected to the connecting bracket 12; the guide body 11 floats in the inspection well 2 so as to monitor the water status in the drainage pipes connected to both ends of the inspection well 2 through the water monitoring unit 13.

[0037] Please refer to Figures 2 to 4 As shown, the guide body 11 is cone-shaped with no corners in the direction of the incoming flow. The upper, flat portion of the guide body 11 is a float, and the lower portion is metal. The overall density of the guide body is lower than that of water. The upper part of the guide body 11 is a float, and the lower part is metal, which can lower the center of gravity and guide the water flow. Furthermore, because the guide body 11 is cone-shaped, it can effectively prevent debris from getting stuck.

[0038] In addition, the float material of the fluid guide 11 is corrosion resistant.

[0039] In some implementations, the floating material includes polyethylene (PE), polypropylene (PP), polyurethane foam (PU), etc., and this application does not impose any restrictions on this. In practical applications, the floating material with the appropriate density can be selected according to the buoyancy requirements.

[0040] Furthermore, a lifting body wing 111 is adopted above the guide body 11. When the water flow velocity is greater than a certain speed, the guide body 11 is in a highly suspended state. When the flow velocity is relatively low, the guide body 11 is prone to running aground. At this time, it can touch the bottom to reduce swaying, thereby ensuring that the whole device is in the water and continuously monitoring water information.

[0041] Please refer to Figures 2 to 4As shown, the connecting bracket 12 is an L-shaped hardened bracket. The connecting bracket 12 can ensure the durability of the cable under twisting conditions, and due to the L-shaped design, it can provide a downward force to the water monitoring module 13 with the weight of the cable when the water level is low, thereby ensuring that the water monitoring module 13 can contact the water in the inspection well 2.

[0042] Please refer to Figures 2 to 4 As shown, the water monitoring unit 13 also has an inverted triangular shape, similar to the front end of the guide tube 11. A temperature probe 134 is located below the water monitoring unit 13, and the temperature probe 134 collects the water temperature information inside the drain pipe. Positioning the temperature probe 134 below the water monitoring unit 13 effectively lowers the equipment's center of gravity.

[0043] For further details, please refer to Figures 2 to 4 As shown, a set of plate-type eddy current generators 131 are symmetrically arranged on both sides of the middle part of the temperature probe 134, which can enhance the acceleration of the fluid around the temperature probe 134, enhance heat exchange, and enable the temperature probe 134 to monitor information more accurately.

[0044] For further details, please refer to Figures 2 to 4 As shown, a compression-type flow enhancement cavity 132 is provided behind the temperature probe 134. Due to the presence of air within the compression-type flow enhancement cavity, under pulsating flow conditions, the gas volume continuously compresses and changes under the influence of wake vortex pressure turbulence, forming resonance. This enhances the mixing effect of the tail fluid, strengthens the pulsating flow of the fluid around the temperature probe 134, enhances heat exchange, reduces the laminar boundary layer thickness of the temperature probe 134, and reduces the thermal inertia of the temperature probe 134, enabling the temperature probe 134 to provide more accurate monitoring information.

[0045] Furthermore, the compressed flow-enhancing cavity 132 is equipped with an ultrasonic cavitation generator. Ultrasonic cavitation refers to the process where, when the ultrasonic energy is sufficiently high, tiny bubbles (cavitation nuclei) existing in the liquid vibrate, grow, and continuously accumulate sound field energy under the action of the ultrasonic field. This further enhances the turbulence of the water surrounding the temperature probe 134, further strengthens the heat exchange effect, reduces the thermal inertia of the temperature probe 134, and enables the temperature probe 134 to provide more accurate monitoring information.

[0046] For further details, please refer to Figures 2 to 4As shown, the lower end of the water monitoring unit 13 is provided with a folded guide surface 133. The unfolded design ensures that the device will not snag on debris as it flows with the water. When the fluid flows through the irregular guide surface 133, it will be deflected. When the guide surface 133 is facing the current, it will generate a lateral thrust. The water monitoring unit 13 will tilt laterally about the connecting bracket 12 as its axis. Subsequently, due to the center of gravity, the tilt will return to its original position and continue to vibrate at a low frequency, thereby enhancing the overall turbulence effect and the shaking of the water monitoring unit 13. This can accelerate the fluid around the temperature probe 134, enhance heat exchange, and enable the temperature probe 134 to monitor information more accurately.

[0047] In some embodiments, please refer to Figures 2 to 4 As shown, the water monitoring module 1 has a streamlined structure, which gradually narrows from top to bottom. This reduces the flow area and ensures stable flow, while the streamlined shape can minimize the accumulation of debris on the device, thus ensuring its normal operation.

[0048] Furthermore, the vertical section of the L-shaped hardened bracket is connected to a cable, which is used to transmit the monitoring information collected by the water monitoring module to the processing module. The processing module determines whether the drainage pipe is damaged or leaking based on the received monitoring information.

[0049] Furthermore, the processing module includes an alarm unit, which includes an SMS alarm and / or a warning light.

[0050] When the urban drainage network is operating normally, the type of water within the drainage pipes is fixed. However, due to the temperature differences between different types of water, when a defect in the pipe causes mixing of multiple water types, the water temperature will change significantly due to temperature neutralization. Therefore, after the water monitoring module 1 acquires monitoring information about the water status within the drainage pipe, the cable transmits the monitoring information to the processing module. At this time, the processing module will determine whether the drainage pipe is damaged or leaking based on the monitoring information, so that maintenance personnel can repair the drainage pipe in a timely manner.

[0051] In some embodiments, the temperature probe 134 within the water monitoring unit 13 collects water temperature information. If the drain pipe is damaged or leaking, the water inside will mix. At this time, the water temperature will change significantly due to temperature neutralization. The processing module analyzes the monitoring information to determine if the water temperature change exceeds a preset threshold. If it does, it indicates that the drain pipe is damaged or leaking.

[0052] The water monitoring module 1 in the drainage network anti-fouling monitoring device provided in the above embodiments of this application can float in the inspection well 2, thereby monitoring the water status in the drainage pipes connected to both ends of the inspection well 2 in real time.

[0053] In some embodiments, the drainage pipe network anti-fouling monitoring device provided in this application is placed in an inspection well, and the temperature probe 134 integrated below the water monitoring module 1 will collect the water temperature information accordingly. When the drainage pipe is not damaged or leaking, the water in the drainage pipe is stable, and the water temperature information will show periodic regular fluctuations, which are related to the residents' water usage patterns in the morning and evening. However, once the drainage pipe experiences groundwater leakage, rainwater mixing, or illegal wastewater discharge, the water in the drainage pipe will become mixed. At this time, the water temperature will change significantly compared to a sunny day without mixing. At this time, the processing module receives the monitoring information and analyzes whether the change in water temperature information exceeds a set threshold. If it exceeds the preset threshold, it indicates that the drainage pipe is damaged or leaking. At this time, the alarm unit in the processing module will issue a warning so that maintenance personnel can maintain the drainage pipe in a timely manner.

[0054] As described above, the drainage network anti-fouling monitoring device provided in this application adopts a special streamlined structure design to enable the water monitoring module inside the drainage pipe to float in the inspection well, thereby avoiding a large amount of garbage from getting stuck and ensuring that the drainage network anti-fouling monitoring device can operate normally.

[0055] The descriptions of the processes or structures corresponding to the above figures each have their own emphasis. For parts of a process or structure that are not described in detail, please refer to the relevant descriptions of other processes or structures.

[0056] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
