Description

Technical Field

[0001] The present invention relates to a rainwater monitoring device, in particular to a monitoring device for determining initial rainwater, and belongs to the field of rainwater monitoring devices. Background Art

[0002] In the fields of urban rainwater management and environmental protection, the accurate determination and effective treatment of initial rainwater are of great importance. Initial rainwater is polluted rainwater formed by washing surface pollutants in the initial stage of rainfall, and the concentration of pollutants it contains is relatively high. If it is directly discharged into natural water bodies or the diversion treatment with later cleaner rainwater is improper, it will cause serious pollution to the water environment and affect the ecological balance.

[0003] Currently, there are many problems to be solved urgently in the determination of initial rainwater in the prior art. Most devices rely on fixed thresholds to determine initial rainwater, such as using a fixed rainfall amount (such as 2 mm) or time (such as 30 minutes) as the determination standard. However, in actual situations, the pollutant concentrations, rainfall intensities, and surface characteristics in different regions vary greatly. This fixed-threshold determination method lacks flexibility and adaptability, and it is difficult to accurately define initial rainwater, resulting in insufficient pertinence of treatment measures.

[0004] Therefore, it is urgent to improve the monitoring device for determining initial rainwater to solve the above existing problems. Summary of the Invention

[0005] The object of the present invention is to provide a monitoring device for determining initial rainwater. Rainwater is collected by a rainwater collection funnel and flows into the lower flip funnel through a bottom quantitative drainage hole. When the gravity of the rainwater received by the flip funnel exceeds the counterweight, the balance rod swings, driving the trigger magnet to move. The swing sensor detects the magnetic field change signal and converts it into an electrical signal and transmits it to the edge algorithm processing module. The temperature and humidity sensor measures the ambient temperature and humidity data in real time, and the timer records the time information. Both transmit the data to the edge algorithm processing module. The edge algorithm processing module analyzes and processes the data to judge the rainfall amount, rainfall intensity, and the time of initial rain, so as to dynamically adjust the cumulative rainfall threshold and the judgment conditions for initial rainwater.

Detailed implementation manners

[0034] The following will detail the implementation manners of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0035] Such as Figure 1 - Figure 10As shown in the figure, the monitoring device for determining initial rainwater provided in this embodiment includes a housing 1 and a rain gauge assembly 2. Since the device is usually used in an outdoor environment, complex natural conditions may damage internal components. The presence of the housing 1 can extend the service life of the device and ensure the normal progress of monitoring work. The rain gauge assembly 2 is used to calculate the rainfall. The rain gauge assembly 2 includes a diversion trough 3, a balance rod 4, and a swing sensor 5. A rainwater collection funnel 6 is provided directly above the diversion trough 3. The diversion trough 3 provides a space for the installation and swing of the balance rod 4 and is also used to receive rainwater from the rainwater collection funnel 6. The swing sensor 5 is used to calculate the number of swings of the balance rod 4. A quantitative water discharge hole 7 is opened at the bottom of the rainwater collection funnel 6. The rainwater collection funnel 6 collects rainfall and guides the rainwater into the diversion trough 3. At the same time, the quantitative water discharge hole 7 at the bottom can control the amount of rainwater entering the diversion trough 3, making the rainfall measurement more accurate and stable. The balance rod 4 is arranged inside the diversion trough 3 in a lever structure. The balance rod 4, as the core measurement component, uses the lever principle to swing according to the force change at both ends. A rotating rod 8 is rotatably connected to the center of the balance rod 4, and both ends of the rotating rod 8 are fixedly connected to the diversion trough 3. The rotating rod 8 serves as the rotation fulcrum of the balance rod 4, enabling the balance rod 4 to swing around it, ensuring that the swinging action of the balance rod 4 is stable and repeatable. A counterweight 9 is threadedly connected to the head end of the balance rod 4. There are differences in rainfall intensity and rainfall distribution in different regions. The adjustable counterweight 9 enables the rain gauge to be calibrated according to the actual situation, improving the versatility and measurement accuracy of the device. The torque generated by the counterweight 9 cancels out the water body torque, triggering the balance rod 4 to swing. A trigger magnet 10 is fixedly connected to the lower bottom surface of the tail end of the balance rod 4. The swing sensor 5 is fixed on the outer wall of the diversion trough 3. The swing sensor 5 forms a magnetic induction cooperation with the trigger magnet 10. The trigger magnet 10 moves as the tail end of the balance rod 4 swings, forming a magnetic induction cooperation with the swing sensor 5 fixed on the outer wall of the diversion trough 3, converting the swing of the balance rod 4 into a magnetic field change signal, which is then detected by the swing sensor 5. The tail end of the balance rod 4 is located directly below the quantitative water discharge hole 7. A tipping funnel 11 is rotatably connected to the upper surface of the tail end of the balance rod 4. The tipping funnel 11 is used to receive the rainwater flowing down from the quantitative water discharge hole 7. When the gravity of the rainwater in the tipping funnel 11 exceeds that of the counterweight 9, it will cause the balance rod 4 to swing. Finally, the balance rod 4 drives the tipping funnel 11 to descend and contact the diversion trough 3, and the tipping funnel 11 flips to pour the rainwater into the diversion trough 3. A drain pipe 12 is connected to the lower end of the diversion trough 3, and the rainwater in the diversion trough 3 is discharged through the drain pipe 12;

[0036] Inside the housing 1, an edge algorithm processing module 13 and a timer 14 are fixedly connected. On the outer wall of the housing 1, a temperature and humidity sensor 15 is fixedly connected. Both the timer 14 and the temperature and humidity sensor 15 are electrically connected to the edge algorithm processing module 13. The swing sensor 5 is electrically connected to the edge algorithm processing module 13. When the data processing module calculates the cumulative rainfall value by counting the number of pulses, a certain compensation algorithm can be adopted. Considering the possible errors caused by continuous rain falling during the swing of the balance rod 4, by analyzing and modeling factors such as the swing period, historical rainfall data, and local rainfall intensity characteristics, the measurement data is corrected at the software level. For example, according to the common local rainfall intensity, the possible additional rainfall during the swing of the balance rod 4 is estimated and corresponding compensation is made in the final rainfall calculation result to further improve the measurement accuracy. At the same time, the edge algorithm processing module 13 receives data from the swing sensor 5, the timer 14, and the temperature and humidity sensor 15, and comprehensively analyzes the rain-related signals detected by the swing sensor 5 in combination with the temperature and humidity data and time information, and processes the data in real time at a position close to the data source without transmitting a large amount of raw data to a remote server, reducing data transmission delay and network burden. The timer 14 records the time information and transmits the time data to the edge algorithm processing module 13, which helps the edge algorithm processing module 13 analyze the change of rainfall over time by providing accurate time stamps. The temperature and humidity sensor 15 measures the temperature and humidity of the environment in real time and transmits the temperature and humidity data to the edge algorithm processing module 13. According to the temperature and humidity data, rainy weather and dry weather can be further judged.

[0037] Among them, as Figure 1 - Figure 10 shown, a rainwater collection port 21 is opened at the upper end of the housing 1. The rainwater collection port 21 enables rainwater to enter the device for subsequent processing and measurement. A filter screen 22 is fixedly connected to the inner wall of the housing 1 near the rainwater collection port 21. When rainwater enters the device, the filter screen 22 can effectively block larger particle impurities such as leaves, branches, and dust. If these impurities enter the subsequent measurement components, they may interfere with the measurement process, resulting in inaccurate data, or even block the pipeline or damage the equipment. Below the filter screen 22, there is a water diversion funnel 23. The water diversion funnel 23 is located directly above the rainwater collection funnel 6. The water diversion funnel 23 guides the rainwater filtered by the filter screen 22 to the rainwater collection funnel 6 below through its funnel shape, ensuring that the rainwater can be concentrated and smoothly flow into the rainwater collection funnel 6, avoiding the rainwater from splashing everywhere or flowing disorderly on the inner wall of the housing 1, thus ensuring the efficiency and stability of rainwater collection;

[0038] Among them, as Figure 1 - Figure 10As shown in the figure, a water collecting area assembly 31 is provided at the upper end of the housing 1. The water collecting area assembly 31 includes a fixed measuring rod 32, a fixed ring 33, and a sliding ring 34 slidably connected to the fixed measuring rod 32. The fixed measuring rod 32 is fixedly connected to the housing 1. The fixed ring 33 is sleeved on the outer wall of the lower end of the fixed measuring rod 32. The fixed measuring rod 32 provides a vertical support structure for the water collecting area assembly 31 to ensure the stability of the entire mechanism and serves as a guide rail for the up and down sliding of the sliding ring 34. A plurality of main keels 35 are rotatably connected to the outer wall of the fixed ring 33. A standard-size water permeable membrane 36 is fixedly connected to one side of the plurality of main keels 35. A plurality of secondary keels 37 are rotatably connected to the outer wall of the sliding ring 34. The plurality of main keels 35 correspond to the plurality of secondary keels 37 one by one, and one end of the secondary keel 37 is rotatably connected to the outer wall of the main keel 35. A plurality of drainage holes 38 are formed in the upper surface of the fixed ring 33. The drainage holes 38 are directly above the rainwater collection port 21. The fixed ring 33 is fixed to the outer wall of the lower end of the fixed measuring rod 32, serving as the rotation fulcrum of the main keel 35 and providing a fixed connection point for one end of the standard-size water permeable membrane 36. At the same time, the drainage holes 38 formed therein facilitate the water received by the standard-size water permeable membrane 36 to drain into the rainwater collection port 21. The sliding ring 34 is slidably connected to the fixed measuring rod 32. By moving up and down, its position on the fixed measuring rod 32 is changed, thereby driving the secondary keel 37 to move, realizing the adjustment of the unfolded area of the standard-size water permeable membrane 36, and thus changing the water collecting area. The standard-size water permeable membrane 36 directly receives rainfall and is the main component for collecting rainwater. It guides the rainwater to the drainage holes 38 of the fixed ring 33 and then flows into the rainwater collection port 21 for subsequent monitoring of flow rate, water quality, etc.;

[0039] Further, as Figure 1 - Figure 10As shown, a cavity 41 is formed inside the fixed measuring rod 32. A sliding block 42 is slidably connected inside the cavity 41. Both sides of the sliding block 42 extend to the outer wall of the fixed measuring rod 32 and are fixedly connected to the sliding ring 34. A lead screw 43 is rotatably connected inside the cavity 41. The lead screw 43 passes through the sliding block 42 and is threadedly connected. The cavity 41 inside the fixed measuring rod 32 provides a space for accommodating components such as the sliding block 42 and the lead screw 43, and at the same time limits the movement track of the sliding block 42, so that it can only slide linearly along the direction of the lead screw 43 inside the cavity 41. The sliding block 42 slides along the direction of the lead screw 43 inside the cavity 41 and is fixedly connected to the sliding ring 34 through the extension of both sides, converting the rotational motion of the lead screw 43 into the up-and-down linear motion of the sliding ring 34, and then driving the secondary keel 37 to move to adjust the water collection area of the standard-size water-permeable membrane 36. The lead screw 43 rotates inside the cavity 41. Through the threaded connection with the sliding block 42, its own rotational motion is converted into the linear motion of the sliding block 42. A first bevel gear 44 is fixedly connected to the lower end of the lead screw 43. The first bevel gear 44 is fixedly connected to the lower end of the lead screw 43, realizing the conversion of the power direction. A second bevel gear 45 is meshed with one side of the first bevel gear 44. A driving motor 46 is fixedly connected to the top inside the housing 1. The output end of the driving motor 46 is connected to the second bevel gear 45. The driving motor 46 serves as the power source of the entire water collection area assembly 31, providing the power required to drive the lead screw 43 to rotate. By controlling the forward and reverse rotation and speed of the driving motor 46, the rotation direction and speed of the lead screw 43 are controlled, and then the position and water collection area of the sliding ring 34 are accurately adjusted. The second bevel gear 45 is meshed with the first bevel gear 44, receiving the power from the output shaft of the driving motor 46 and transmitting it to the first bevel gear 44, and then driving the lead screw 43 to rotate. The driving motor 46 is electrically connected to the edge algorithm processing module 13. The edge algorithm processing module 13 can make an intelligent decision based on the data analysis result and send a control instruction to the driving motor 46 to adjust the rotation speed, rotation direction or start-stop state of the motor;

[0040] Among them, as Figure 1 - Figure 10As shown, on one side of the outer wall of the housing 1 close to the temperature and humidity sensor 15, a manual parameter input panel 51 is fixedly connected. Inside the housing 1, a wireless communication module 52 is fixedly connected. Both the wireless communication module 52 and the manual parameter input panel 51 are electrically connected to the edge algorithm processing module 13. The manual parameter input panel 51 gives the operator a certain degree of autonomy. In some cases, when GIS data cannot be obtained, is inaccurate, or specific assumptions and adjustments are required, key parameters can be manually input to calculate the catchment area. The wireless communication module 52 is responsible for wireless data communication with external devices or systems. On the one hand, it can receive important information such as terrain elevation data, surface permeability coefficient, and drainage pipe network topology parameters from the GIS mapping system, and transmit these data to the edge algorithm processing module 13 for effective calculation and analysis of related items such as the catchment area. On the other hand, it can also send the data processed by the edge algorithm processing module 13 to a remote server or other terminal devices to achieve remote storage, sharing, and further analysis of the data. The edge algorithm processing module 13 is electrically connected to the manual parameter input panel 51 and can receive data from the manual parameter input panel 51, integrating these manually input parameters into its data processing and analysis process. The edge algorithm processing module 13 is electrically connected to the wireless communication module 52 to achieve two-way data flow. In addition, it receives remote control instructions transmitted by the wireless communication module 52, enabling the edge algorithm processing module 13 to make corresponding functional adjustments according to remote operations, realizing remote intelligent management of the device.

[0041] Among them, as Figure 1 - Figure 10 shown, the other end of the drainage pipe 12 is connected to a tee 61. The drainage pipe 12 drains the excess rainwater in the diversion trough 3 into the tee 61. The tee 61, as a flow splitting device, provides two different drainage path options. The inner bottom surface of the housing 1 is fixedly connected with an initial rainwater collection bin 62. One end of the tee 61 extends into the interior of the initial rainwater collection bin 62. The initial rainwater collection bin 62 is used to store the initial rainwater diverted through the tee 61, providing samples for subsequent research on the component analysis and pollutant monitoring of the initial rainwater. The other end of the tee 61 extends outside the housing 1 and can discharge the rainwater into the external environment. An electric flow splitting valve 63 is fixedly connected inside the tee 61. The electric flow splitting valve 63 controls the flow direction of the rainwater in the tee 61. By opening or closing different ports, it determines whether the rainwater flows into the initial rainwater collection bin 62 or is discharged outside the housing 1. The electric flow splitting valve 63 is electrically connected to the edge algorithm processing module 13. The edge algorithm processing module 13 analyzes and judges whether rainwater needs to be collected based on the data from each sensor and preset rules and algorithms. Then, according to the analysis result, it sends a control signal to the electric flow splitting valve 63 to adjust the on-off state of the electric flow splitting valve 63, thereby controlling the flow direction of the rainwater.

[0042] Among them, asFigure 1 - Figure 10 As shown in Figure 10 , a portable water quality monitor I 71 is fixedly connected inside the diversion channel 3. One end of the tee pipe 61 extending to the outside of the housing 1 is provided with a sleeve 72. A portable water quality monitor II 73 is arranged inside the sleeve 72. Both the portable water quality monitor I 71 and the portable water quality monitor II 73 are electrically connected to the edge algorithm processing module 13. The portable water quality monitor I 71 detects the water quality of the rainwater in the diversion channel 3 in real time and transmits the data to the edge algorithm processing module 13 in a timely manner. The edge algorithm processing module 13 determines whether to collect or discharge this rainwater. The portable water quality monitor II 73 detects the water quality of the rainwater discharged from the tee pipe 61 to the outside of the housing 1, obtains various water quality parameters in the same way, and transmits the data to the edge algorithm processing module 13. By establishing a correlation between this data and the rainfall data, a data chain is established through the edge computing module.

[0043] Among them, as Figure 1 - Figure 10 As shown in Figure 10 , a water level switch 81 is arranged inside the initial rainwater collection bin 62. A water pump 82 is fixedly connected to the upper surface of the initial rainwater collection bin 62. The water inlet end of the water pump 82 is connected with a water inlet pipe 83, and the water discharge end of the water pump 82 is connected with a water discharge pipe 84. One end of the water discharge pipe 84 extends to the outer wall of the housing 1. Both the water level switch 81 and the water pump 82 are electrically connected to the edge algorithm processing module 13. The water level switch 81 monitors the water level height inside the initial rainwater collection bin 62 in real time and converts the water level information into an electrical signal and feeds it back to the edge algorithm processing module 13. When the water level reaches the preset threshold, the water level switch 81 will trigger a corresponding signal to inform the edge algorithm processing module 13 of the water level state in the collection bin. The edge algorithm processing module 13 controls the electric flow dividing valve 63 accordingly based on the information fed back by the water level switch 81. The water pump 82 provides a controllable power source and can efficiently pump out the rainwater and transfer it to a designated position.

[0044] Among them, as Figure 1 - Figure 10 As shown in Figure 10 , a contact rain sensor device 91 is fixedly connected to the upper end of the fixed measurement benchmark 32. The contact rain sensor device 91 is used in cooperation with the temperature and humidity sensor 15 to enhance the accuracy of rainfall event recognition. The contact rain sensor device 91 is electrically connected to the edge algorithm processing module 13. The contact rain sensor device 91 is in direct contact with the rainwater and determines the occurrence of a rainfall event by sensing the presence of the rainwater. It can quickly and sensitively respond to the touch of raindrops, convert the physical contact into an electrical signal, provide instant information for rainfall monitoring, and is convenient for determining the time period of the last rainfall.

[0045] Among them, as Figure 1 - Figure 10As shown in the figure, a bracket 101 is fixedly connected to one side of the housing 1. A solar panel 102 is fixedly connected to one side of the bracket 101. The solar panel 102 is electrically connected to the electrical equipment inside the housing 1. The bracket 101 fixes the solar panel 102 at a specific position to ensure that it can receive solar radiation at an appropriate angle. At the same time, it keeps a certain distance between the solar panel 102 and the housing 1 of the monitoring equipment to avoid occlusion and interference, and provides a stable support for the solar panel 102 so that it can remain stable under different weather conditions. The solar panel 102 uses the photovoltaic effect to convert solar energy into electrical energy to provide power support for the electrical equipment inside the housing 1 to meet the energy requirements for the operation of the equipment.

[0046] As Figure 1 - Figure 10 shown, the principle of a monitoring device for determining initial rainwater provided in this embodiment is as follows: Key parameters are manually input through the manual parameter input panel 51. The temperature and humidity sensor 15 measures the temperature and humidity of the environment in real time and transmits the data to the edge algorithm processing module 13. During rainfall, the contact rain sensing device 91 directly contacts the rainwater to sense the presence of rainwater to determine the occurrence of a rainfall event. The timer 14 records the time information and transmits the time data to the edge algorithm processing module 13. The rainwater enters the device through the rainwater collection port 21 at the upper end of the housing 1, first passes through the filter screen 22 and then falls into the water diversion funnel 23. The rainwater falls into the rainwater collection funnel 6 below through the water diversion funnel 23, and then falls into the tipping funnel 11 through the quantitative drain hole 7. When the gravity of the rainwater in the tipping funnel 11 exceeds the weight of the counterweight 9, the balance rod 4 drives the tipping funnel 11 to swing downward and contact the diversion groove 3. The tipping funnel 11 flips to pour the rainwater into the diversion groove 3. The swing sensor 5 detects the magnetic field change signal, converts the swing of the balance rod 4 into an electrical signal, and transmits it to the edge algorithm processing module 13. At the same time, the portable water quality monitor 71 performs corresponding detection on the rainwater in the diversion groove 3 and transmits the detection data to the edge algorithm processing module 13. The rainwater flows into the tee 61 through the drain pipe 12. The edge algorithm processing module 13 controls the opening or closing of the electric diverter valve 63 to determine whether the rainwater flows into the initial rainwater collection bin 62 or is discharged to the outside of the housing 1. The water level switch 81 monitors the water level height in real time and feeds back the water level information to the edge algorithm processing module 13. After receiving the start instruction from the edge algorithm processing module 13, the water pump 82 pumps rainwater from the collection bin through the inlet pipe 83 and discharges the rainwater to the outer wall of the housing 1 through the outlet pipe 84. The portable water quality monitor 73 performs water quality detection on the rainwater discharged to the outside of the housing 1 and also transmits the data to the edge algorithm processing module 13.
