Description

TECHNICAL FIELD

[0001] The application relates to the technical field of drainage systems, in particular to a pressure-limited drainage intelligent system for underground water. BACKGROUND

[0002] With the acceleration of urbanization and the increase of population density, underground water resources are facing increasingly severe challenges. In some areas, due to the imperfection of the drainage system, the underground water pressure is too high, resulting in frequent problems such as ground subsidence and damage to building foundations. In addition, due to the complexity of the underground environment, the traditional drainage system is difficult to meet the real-time, accurate and efficient monitoring and control requirements.

[0003] In order to solve the above problems, the drainage system is reformed and optimized through intelligent technology. Advanced technologies such as Internet of Things, big data and artificial intelligence are adopted to realize remote monitoring, automatic control and intelligent management of underground water. Specifically, the intelligent system can monitor the underground water level, pressure, flow and other key parameters in real time, and automatically adjust the operating parameters of the drainage pump station according to these parameters, so as to realize accurate control of the underground water level. SUMMARY

[0004] The embodiment of the application provides a pressure-limited drainage intelligent system for underground water, which solves the problem of excessive underground water pressure in the prior art, resulting in ground subsidence and damage to building foundations, and realizes accurate control of the flow rate of underground water flowing into the water collecting pool, which helps to ensure that the underground water level fluctuates within a preset threshold range and avoids potential risks caused by excessively high or low water level.

[0005] The embodiment of the application provides a pressure-limited drainage intelligent system for underground water, which includes a water level monitoring module, a valve control module, an automatic control cabinet and a monitoring platform.

[0006] The water level monitoring module and the valve control module are connected with the automatic control cabinet, and the automatic control cabinet is connected with the monitoring platform.

[0007] The water level monitoring module includes a water level acquisition unit, a plurality of monitoring points are arranged in the underground water monitoring area, which is used for acquiring real-time data of the underground water level, obtaining first underground water level data, and uploading the first underground water level data to the automatic control cabinet;

[0008] The water level monitoring module is a water level monitor arranged in the underground water monitoring area, which is mainly used for monitoring the water level of the underground water;

[0009] The valve control module includes a judgment module, which is used for judging whether the first underground water level data exceeds the preset first upper limit threshold of the underground water level by pre-setting the first upper limit threshold and the first lower limit threshold of the underground water level;

[0010] The valve control module also includes a valve regulating unit for adjusting the opening size of the electric valve, including:

[0011] S101 If the groundwater level exceeds the preset upper limit threshold, an early warning signal is sent to the automated control cabinet. The automated control cabinet controls the electric valve and water pump by sending a remote operation signal, turns on the water pump and fully opens the electric valve, allowing groundwater to flow into the collection tank.

[0012] S102, a second upper limit threshold and a second lower limit threshold for groundwater level are set at the midpoint between the first upper limit threshold and the first lower limit threshold, wherein the second upper limit threshold is lower than the first upper limit threshold, the second lower limit threshold is higher than the first lower limit threshold, and the second upper limit threshold is higher than the second lower limit threshold.

[0013] S103 When the groundwater level drops to the second lower threshold of the groundwater level by pumping water into the collection tank, the automatic control cabinet sends a remote operation signal to gradually reduce the opening and closing size of the electric valve, so that the flow rate of groundwater into the collection tank decreases and the groundwater level gradually rises.

[0014] S104 When the groundwater level is pumped into the collection tank by the water pump, and the groundwater level rises to the second upper threshold of the groundwater level, the automatic control cabinet sends a remote operation signal to gradually increase the opening and closing size of the electric valve, so that the flow rate of groundwater into the collection tank increases and the groundwater level gradually decreases.

[0015] The valve control module includes an electric valve installed on the inlet pipe of the water collection tank. The opening and closing speed of the valve is adjusted by an electric actuator. The valve control module also includes a water pump, which draws groundwater to the water collection tank.

[0016] The automated control cabinet sends real-time data on groundwater levels, the operating status of electric valves, and the start / stop status of drainage pumps to the monitoring platform. The monitoring platform can remotely control the operating status of electric valves and the start / stop status of drainage pumps.

[0017] The valve control module also includes a water collection tank return unit, which switches to the water collection tank return unit when the groundwater level is lower than the first threshold of the groundwater level.

[0018] Specifically, the automated control cabinet determines whether the groundwater level is lower than the preset first lower limit threshold and cannot be restored after a certain period of time. If the automated control cabinet determines the result, the water collection tank return unit is activated.

[0019] The water collection tank return unit starts working, injecting the water stored in the water collection tank back into the groundwater monitoring area through the return pipe to replenish the groundwater level.

[0020] During the backflow process, the water level monitoring module continues to monitor the groundwater level and feeds back the real-time data to the automated control cabinet.

[0021] When the groundwater level rises to the preset second lower limit threshold, the automatic control cabinet sends a signal to shut down the water collection tank return unit.

[0022] The valve control module also includes a weather forecasting unit for predicting upcoming weather conditions, including:

[0023] S201: Collect historical meteorological data to obtain a historical meteorological dataset, and analyze the meteorological data in the historical meteorological dataset, such as rainfall, wind speed, and wind direction.

[0024] S202 uses meteorological models or machine learning algorithms to predict the weather conditions for the next week. It should be noted that rainy weather is extracted from the forecast.

[0025] S203 sends the predicted rainfall weather to the data analysis unit and the automation control cabinet;

[0026] The valve control module also includes a data analysis unit for predicting future groundwater level trends, including:

[0027] S301 collects historical rainfall and weather data and corresponding groundwater level data;

[0028] S302, using statistical analysis and machine learning methods to establish a predictive model between groundwater level and rainy weather;

[0029] S303, based on the forecast results of the weather forecast unit, uses a forecasting model to predict the future trend of groundwater level changes and sends the forecast results to the automation control cabinet.

[0030] The automated control cabinet receives forecast results from the weather forecasting unit and the data analysis unit. Based on the forecast results, it adjusts the opening size of the electric valves in advance to adapt to the upcoming rainy weather and changes in groundwater level. At the same time, it monitors the operating status of the electric valves and water pumps to ensure stable system operation.

[0031] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0032] By adjusting the opening and closing size of the electric valve through an electric actuator, the flow rate of groundwater into the collection tank can be precisely controlled, which helps to ensure that the groundwater level fluctuates within a preset threshold range and avoids potential risks caused by excessively high or low water levels.

[0033] Precise flow rate control can reduce unnecessary energy waste. When the groundwater level approaches the preset threshold, the operating time of the water pump can be reduced by gradually decreasing or increasing the opening and closing size of the electric valve, thus saving energy.

[0038] Example 1: As Figure 1 As shown, this application discloses a digital intelligent system for pressure-limited drainage of groundwater, including a water level monitoring module, a valve control module, an automated control cabinet, and a monitoring platform.

[0039] Both the water level monitoring module and the valve control module are connected to the automated control cabinet, and the automated control cabinet is connected to the monitoring platform via a network.

[0040] The water level monitoring module includes a water level acquisition unit, which collects real-time groundwater level data by arranging multiple monitoring points in the groundwater monitoring area, obtains the first groundwater level data, and uploads the first groundwater level data to the automated control cabinet.

[0041] The water level monitoring module is a water level monitoring instrument installed in the groundwater monitoring area, mainly used for monitoring the groundwater level;

[0042] The valve control module includes a judgment module, which uses a preset first upper limit threshold and a first lower limit threshold of the groundwater level to determine whether the first groundwater level data exceeds the preset first upper limit threshold of the groundwater level.

[0043] The valve control module also includes a valve regulating unit for adjusting the opening size of the electric valve, including:

[0044] S101 If the groundwater level exceeds the preset upper limit threshold, an early warning signal is sent to the automated control cabinet. The automated control cabinet controls the electric valve and water pump by sending a remote operation signal, turns on the water pump and fully opens the electric valve, allowing groundwater to flow into the collection tank.

[0045] S102, a second upper limit threshold and a second lower limit threshold for groundwater level are set at the midpoint between the first upper limit threshold and the first lower limit threshold, wherein the second upper limit threshold is lower than the first upper limit threshold, the second lower limit threshold is higher than the first lower limit threshold, and the second upper limit threshold is higher than the second lower limit threshold.

[0046] S103 When the groundwater level drops to the second lower threshold of the groundwater level by pumping water into the collection tank, the automatic control cabinet sends a remote operation signal to gradually reduce the opening and closing size of the electric valve, so that the flow rate of groundwater into the collection tank decreases and the groundwater level gradually rises.

[0047] S104 When the groundwater level is pumped into the collection tank by the water pump, and the groundwater level rises to the second upper threshold of the groundwater level, the automatic control cabinet sends a remote operation signal to gradually increase the opening and closing size of the electric valve, so that the flow rate of groundwater into the collection tank increases and the groundwater level gradually decreases.

[0048] The valve control module includes an electric valve installed on the inlet pipe of the water collection tank. The opening and closing speed of the valve is adjusted by an electric actuator. The valve control module also includes a water pump, which draws groundwater to the water collection tank.

[0049] The automated control cabinet sends real-time data on groundwater levels, the operating status of electric valves, and the start / stop status of drainage pumps to the monitoring platform. The monitoring platform can remotely control the operating status of electric valves and the start / stop status of drainage pumps.

[0050] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0051] By adjusting the opening and closing size of the electric valve through the electric actuator, the flow rate of groundwater into the collection tank can be precisely controlled, which helps to ensure that the groundwater level fluctuates within the preset threshold range and avoids the potential risks caused by excessively high or low water levels.

[0052] Precise flow rate control can reduce unnecessary energy waste. When the groundwater level approaches the preset threshold, the operating time of the water pump can be reduced and energy saved by gradually decreasing or increasing the opening and closing size of the electric valve.

[0053] Example 2: In Example 1, the groundwater level is lower than the preset groundwater level first threshold, and the groundwater level is too low and cannot be replenished in time due to drought and other reasons.

[0054] Therefore, the embodiments of this application are optimized based on the above embodiments.

[0055] In some embodiments, the valve control module also includes a water collection tank return unit, which switches to the water collection tank return unit when the groundwater level is lower than a first threshold.

[0056] Specifically, the automated control cabinet determines whether the groundwater level is lower than the preset first lower limit threshold and cannot be restored after a certain period of time. If the automated control cabinet determines the result, the water collection tank return unit is activated.

[0057] The water collection tank return unit starts working, injecting the water stored in the water collection tank back into the groundwater monitoring area through the return pipe to replenish the groundwater level.

[0058] During the backflow process, the water level monitoring module continues to monitor the groundwater level and feeds back the real-time data to the automated control cabinet.

[0059] When the groundwater level rises to the preset second lower limit threshold, the automatic control cabinet sends a signal to shut down the water collection tank return unit.

[0060] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0061] The water collection pool return unit can effectively utilize the water resources stored in the pool to replenish groundwater when the groundwater level is too low and cannot be replenished in time due to drought or other reasons, thus ensuring that the groundwater level is maintained at a certain level and maintaining ecological balance and the safety of groundwater resources.

[0062] By combining the automated control cabinet and the water level monitoring module, real-time monitoring and intelligent management of groundwater levels are achieved. When the water level is lower than the preset first threshold, the water collection tank return unit is automatically triggered to replenish water, and it automatically shuts off when the water level rises to the second threshold, without the need for manual intervention, thus improving management efficiency.

[0063] Example 3: In Examples 1 and 2, during rainy weather, the drainage volume of groundwater increases, the groundwater level rises rapidly, and the groundwater level rises rapidly, posing a threat to the ground and surrounding facilities.

[0064] Therefore, the embodiments of this application are optimized based on the above embodiments.

[0065] The valve control module also includes a weather forecasting unit for predicting upcoming weather conditions, including:

[0066] S201: Collect historical meteorological data to obtain a historical meteorological dataset, and analyze the meteorological data in the historical meteorological dataset, such as rainfall, wind speed, and wind direction.

[0067] S202 uses meteorological models or machine learning algorithms to predict the weather conditions for the next week. It should be noted that rainy weather is extracted from the forecast.

[0068] S203 sends the predicted rainfall weather to the data analysis unit and the automation control cabinet;

[0069] The valve control module also includes a data analysis unit for predicting future groundwater level trends, including:

[0070] S301 collects historical rainfall and weather data and corresponding groundwater level data;

[0071] S302, using statistical analysis and machine learning methods to establish a predictive model between groundwater level and rainy weather;

[0072] S303, based on the forecast results of the weather forecast unit, uses a forecasting model to predict the future trend of groundwater level changes and sends the forecast results to the automation control cabinet.

[0073] The automated control cabinet receives forecast results from the weather forecasting unit and the data analysis unit. Based on the forecast results, it adjusts the opening size of the electric valves in advance to adapt to the upcoming rainy weather and changes in groundwater level. At the same time, it monitors the operating status of the electric valves and water pumps to ensure stable system operation.

[0074] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0075] Through weather forecasting and data analysis, groundwater levels can be predicted and adjusted in advance, effectively avoiding rapid rises in groundwater levels and potential risks caused by rainy weather. This improves the intelligence level of groundwater management, reduces the need for manual intervention, and increases management efficiency.

[0076] By precisely controlling the opening size of the electric valve, the flow rate of groundwater into the collection tank is precisely controlled, which helps to ensure that the groundwater level fluctuates within the preset threshold range and maintains the safety of groundwater resources.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations.
