Description

Technical Field

[0001] The present invention relates to the technical field of drainage systems, and in particular to a digital intelligent pressure-limited drainage system for groundwater. Background Art

[0002] With the acceleration of urbanization and increasing population density, groundwater resources face increasingly severe challenges. In some areas, due to inadequate drainage systems, groundwater pressure is excessively high, leading to frequent problems such as land subsidence and damage to building foundations. Furthermore, due to the complex underground environment, traditional drainage systems struggle to meet the demands for real-time, accurate, and efficient monitoring and control.

[0003] To address these issues, the company is seeking to transform and optimize its drainage system through digital technologies. This includes the use of advanced technologies such as the Internet of Things, big data, and artificial intelligence to achieve remote monitoring, automatic control, and intelligent management of groundwater. Specifically, the digital system monitors key parameters such as groundwater level, pressure, and flow in real time, and automatically adjusts the operating parameters of drainage pumping stations based on these parameters, thereby achieving precise control of groundwater levels. Summary of the Invention

[0004] The embodiments of the present application solve the problem in the prior art of excessive groundwater pressure leading to ground subsidence and damage to building foundations by providing a digital pressure-limited drainage system for groundwater. This system achieves precise control of the flow rate of groundwater flowing into the collection tank, helps ensure that the groundwater level fluctuates within a preset threshold range, and avoids potential risks caused by excessively high or low water levels.

[0005] An embodiment of the present application provides a digital and intelligent pressure-limited drainage system for groundwater, including: a water level monitoring module, a valve control module, an automated control cabinet and a monitoring platform.

[0006] The water level monitoring module and the valve control module are both connected to the automation control cabinet, and the automation control cabinet is connected to the monitoring platform through a network.

[0007] The water level monitoring module includes a water level acquisition unit, which is used to collect real-time data of the groundwater level by arranging multiple monitoring points in the groundwater monitoring area, obtain first groundwater level data, and upload the first groundwater level data to the automation control cabinet;

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

[0009] The valve control module includes a judgment module, which is used to judge whether the first groundwater level data exceeds the preset first upper limit threshold of the groundwater level by presetting a first upper limit threshold and a first lower limit threshold of the groundwater level;

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

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

[0012] S102, setting a second upper threshold and a second lower threshold of the groundwater level at a midpoint between the first upper threshold and the first lower threshold of the groundwater level, wherein the second upper threshold is lower than the first upper threshold, the second lower threshold is higher than the first lower threshold, and the second upper threshold is higher than the second lower threshold;

[0013] S103: When the groundwater level is pumped into the water collection tank by the pump and the groundwater level drops to the second lower threshold of the groundwater level, the automation 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 water collection tank is reduced and the groundwater level gradually rises;

[0014] In step S104, when the groundwater level is pumped into the water collection tank by the pump and reaches the second upper threshold of the groundwater level, the automation control cabinet sends a remote operation signal to gradually increase the opening and closing of the electric valve, thereby increasing the flow rate of groundwater into the water collection tank and gradually reducing the groundwater level;

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

[0016] The automated control cabinet sends the collected real-time data of groundwater level, the operating status of the electric valve, and the start and stop status of the drainage pump to the monitoring platform, which can remotely control the operating status of the electric valve and the start and stop of the drainage pump.

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

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

[0019] The water collection tank return unit starts working, and the water stored in the water collection tank is re-injected 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 real-time data to the automation control cabinet.

[0021] When the groundwater level rises back to the preset second lower threshold of the groundwater level, the automation control cabinet sends a signal to close the water collection tank return unit.

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

[0023] S201, collecting historical meteorological data to obtain a historical meteorological data set, and analyzing meteorological data in the historical meteorological data set, such as rainfall, wind speed, wind direction, etc.;

[0024] S202, using a meteorological model or machine learning algorithm to predict the weather conditions in the next week, it should be noted that rainy weather is extracted;

[0025] S203, sending the predicted rainy weather to the data analysis unit and the automation control cabinet;

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

[0027] S301, collecting historical rain weather data and corresponding groundwater level data;

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

[0029] S303: Based on the prediction results of the weather prediction unit, a prediction model is used to predict the changing trend of the groundwater level in the future, and the prediction results are sent to the automation control cabinet.

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

[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 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 avoid potential risks caused by excessively high or low water levels.

[0033] Precise control of flow rate can reduce unnecessary energy waste. When the groundwater level approaches the preset threshold, the opening and closing size of the electric valve is gradually reduced or increased to reduce the running time of the pump and save energy.

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

[0039] The water level monitoring module and the valve control module are both connected to the automation control cabinet, and the automation control cabinet is connected to the monitoring platform through a network.

[0040] The water level monitoring module includes a water level acquisition unit, which is used to collect real-time data of the groundwater level by arranging multiple monitoring points in the groundwater monitoring area, obtain first groundwater level data, and upload the first groundwater level data to the automation control cabinet;

[0041] The water level monitoring module is a water level monitoring device arranged in the groundwater monitoring area, which is mainly used for monitoring the groundwater level;

[0042] The valve control module includes a judgment module, which is used to judge whether the first groundwater level data exceeds the preset first upper limit threshold of the groundwater level by presetting a first upper limit threshold and a first lower limit threshold of the groundwater level;

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

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

[0045] S102, setting a second upper threshold and a second lower threshold of the groundwater level at a midpoint between the first upper threshold and the first lower threshold of the groundwater level, wherein the second upper threshold is lower than the first upper threshold, the second lower threshold is higher than the first lower threshold, and the second upper threshold is higher than the second lower threshold;

[0046] S103: When the groundwater level is pumped into the water collection tank by the pump and the groundwater level drops to the second lower threshold of the groundwater level, the automation 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 water collection tank is reduced and the groundwater level gradually rises;

[0047] In step S104, when the groundwater level is pumped into the water collection tank by the pump and reaches the second upper threshold of the groundwater level, the automation control cabinet sends a remote operation signal to gradually increase the opening and closing of the electric valve, thereby increasing the flow rate of groundwater into the water collection tank and gradually reducing the groundwater level;

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

[0049] The automated control cabinet sends the collected real-time data of groundwater level, the operating status of the electric valve, and the start and stop status of the drainage pump to the monitoring platform, which can remotely control the operating status of the electric valve and the start and stop of the drainage pump.

[0050] The technical solutions in the above embodiments of the present 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 accurately controlled, which helps to ensure that the groundwater level fluctuates within the preset threshold range and avoid potential risks caused by excessively high or low water levels.

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

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

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

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

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

[0057] The water collection tank return unit starts working, and the water stored in the water collection tank is re-injected 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 real-time data to the automation control cabinet.

[0059] When the groundwater level rises back to the preset second lower threshold of the groundwater level, the automation control cabinet sends a signal to close the water collection tank return unit.

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

[0061] Through the water collection tank return unit, when the groundwater level is too low and cannot be replenished in time due to climate drought and other reasons, the water resources stored in the water collection tank can be effectively utilized to replenish the groundwater, ensure that the groundwater level is maintained at a certain level, and maintain the ecological balance and the safety of groundwater resources.

[0062] Through the cooperation of the automated control cabinet and the water level monitoring module, real-time monitoring and intelligent management of the groundwater level 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 is automatically closed when the water level rises to the second threshold. No human intervention is required, which improves management efficiency.

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

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

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

[0066] S201, collecting historical meteorological data to obtain a historical meteorological data set, and analyzing meteorological data in the historical meteorological data set, such as rainfall, wind speed, wind direction, etc.;

[0072] S303: Based on the prediction results of the weather prediction unit, a prediction model is used to predict the changing trend of the groundwater level in the future, and the prediction results are sent to the automation control cabinet.

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

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

[0075] Through weather forecasting and data analysis, we have achieved early prediction and pre-adjustment of groundwater levels, effectively avoiding the rapid rise in groundwater levels and potential risks caused by rainy weather, improving the intelligence level of groundwater management, reducing the need for manual intervention, and improving management efficiency.

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