Detailed Implementation
[0039] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0040] like Figures 1-7 As shown, the IoT-based intelligent recharge system and device provided in this embodiment includes:
[0041] The IoT platform is used to collect real-time data from sensor modules and send commands to the control module based on preset logic. It supports switching between remote automated control and local manual control. The sensor modules include water level gauges, pressure gauges, and water quality sensors. Further configuration of the IoT platform is as follows:
[0042] Receive real-time data from the sensor module;
[0043] The system status is intelligently determined based on real-time data, and corresponding control commands are sent to the control module.
[0044] Supporting remote monitoring and operation, as well as switching between local manual control modes, the IoT platform serves as the system core. It collects real-time data from sensor modules, including water level, pressure, and water quality, and sends commands to the control module based on preset logic. It also supports switching between remote automated control and local manual control, achieving intelligent management throughout the entire process. Water level gauges monitor the water level in the reinjection well and water treatment device, providing basic data for system start-up, shutdown, and mode switching. Pressure gauges monitor water pressure in the pipeline, ensuring stable pressure during reinjection and backwashing processes to prevent system overload. Water quality sensors monitor water quality indicators before and after reinjection water pretreatment, including iron ion content and turbidity. The control module includes three reinjection solenoid valves. The system includes a backwash solenoid valve 4, a backup pipeline solenoid valve 5, and a water treatment solenoid valve 6. By receiving instructions from the IoT platform, the system controls the opening and closing of each pipeline, enabling function switching. The recharge solenoid valve 3 controls the opening and closing of the recharge path for treated water, while the backwash solenoid valve 4 controls the opening and closing of the path for the backwash medium (water or air) to achieve cleaning and regeneration of the filter element. In the event of a main pipeline failure, the backup pipeline solenoid valve 5 switches to the backup pipeline to ensure continuous system operation. The water treatment solenoid valve 6 controls the opening and closing of the water path for the aeration device and filter element, automating the water treatment process. By integrating sensor data through the IoT platform, the system achieves automated control of functions such as recharge, water treatment, and backwashing, supports remote monitoring and operation, and significantly improves management efficiency.
[0045] The water treatment device includes an aeration tank 1 and a storage tank 7 connected by a water treatment solenoid valve 6. An activated carbon-manganese sand filter element 101 is fixedly installed inside the aeration tank 1. The water treatment device is used for aeration oxidation and filtration purification of water. The aeration tank 1 is located in the first section of the pipeline. Aeration allows the extracted water to fully contact with air, oxidizing reducing substances such as Fe ions into large particles for subsequent filtration removal. The activated carbon-manganese sand filter element 101 is integrated into the subsequent pipeline, utilizing the adsorption of activated carbon and the filtration properties of manganese sand to remove impurities, odors, and residual iron and manganese ions from the water, ensuring that the quality of the reinjection water meets standards. The device also includes a pipeline system, including a reinjection pipeline 100, a backwash pipeline 200, and a backup pipeline 300. Different functions are achieved through switching via a control module. The reinjection solenoid valve 3 is fixedly installed on the reinjection pipeline 100, the backwash solenoid valve 4 is installed on the backwash pipeline 200, and the backup pipeline solenoid valve 5 is installed on the backup pipeline 300.
[0046] Normal reinjection process:
[0047] The reinjection pipeline 100 includes an aeration tank 1, one end of which is connected to an inlet 1001. The inlet 1001 is connected to a reinjection water pump 1002 via a reinjection solenoid valve 3. The reinjection water pump 1002 is connected to the aeration tank 1 via a storage tank 7. The output end of the aeration tank 1 is connected to a reinjection well, and a water level gauge is installed inside the reinjection well.
[0048] When the IoT platform detects through the water level gauge that the reinjection well needs water replenishment, it automatically starts the pumping process:
[0049] The reinjection pump 1002 pumps water through the inlet 1001 and the reinjection solenoid valve 3 into the storage tank 7 and the aeration tank 1. Through aeration, Fe ions and other reducing substances are fully oxidized to form large particulate precipitates.
[0050] Aerated water flows into activated carbon-manganese sand filter element 101 to remove oxidized particles, residual iron and manganese ions and odor impurities.
[0051] The IoT platform controls the opening of the reinjection solenoid valve 3, and the purified water is injected into the reinjection well through the reinjection pipeline.
[0052] After the water level gauge detects that the water level in the well has reached the standard, the platform automatically shuts off the reinjection pump 1002 and the reinjection solenoid valve 3, completing one reinjection process;
[0053] Backwashing process:
[0054] The backwash pipeline 200 includes a reinjection water pump 1002, which is connected to the aeration tank 1 via a backwash solenoid valve 4. The aeration tank 1 is connected to the reinjection well via the backwash solenoid valve 4. A pressure gauge is fixedly installed inside the aeration tank 1. When the pressure gauge detects that the pressure drop through the activated carbon-manganese sand filter element 101 exceeds the threshold, the backwash process is initiated.
[0055] The IoT platform closes the recharge solenoid valve 3 and opens the backwash solenoid valve 4, allowing the backwash medium, such as water, to flow back into the activated carbon-manganese sand filter element 101.
[0056] The backwashing medium flushes out the impurities trapped in the activated carbon-manganese sand filter element 101, thereby regenerating the activated carbon-manganese sand filter element 101.
[0057] After backflushing is completed, the platform closes the backflushing solenoid valve 4, restores the connection and disconnection of the reinjection pipeline 100, and the system continues to standby or execute the reinjection task.
[0058] Backup pipeline activation procedure:
[0059] The backup pipeline 300 includes a backup water pump 1003, which is connected to the storage tank 7 via a backup pipeline solenoid valve 5. The storage tank 7 is connected to the reinjection well via an aeration tank 1. When the reinjection pipeline 100 or the backwash pipeline 200 malfunctions, such as a damaged solenoid valve or a blocked pipeline:
[0060] The IoT platform identifies faults such as abnormal pressure and sudden drop in flow through sensor data and automatically opens the backup pipeline solenoid valve 5.
[0061] The water flow is switched to the backup reinjection pipeline 100 or the backwash pipeline 200 to ensure continuous system operation;
[0062] At the same time, the platform sends a fault alarm to remind maintenance personnel to repair the main line. After the repair is completed, the system can manually or automatically switch back to the main line.
[0063] The system integrates aeration oxidation with activated carbon-manganese sand filter cartridge 101, which efficiently removes iron ions and impurities from groundwater, ensuring that the quality of reinjected water meets the standards and protecting the groundwater aquifer. It has strong functional versatility, with reinjection, backwashing, and backup pipeline switching functions. The system has high reliability, low operation and maintenance costs, and can adapt to complex working conditions and long-term operation needs. It supports the switching between automatic control on the Internet of Things platform and local manual control, and can still operate stably in the event of network failure or special scenarios.
[0064] Furthermore, such as Figure 1 As shown, in the event of an IoT network failure or a special debugging scenario, the solenoid valve can be manually operated through the local control unit to achieve functions such as refilling, backflushing, and pipeline switching, ensuring that the system can still operate under extreme conditions and realizing manual control mode.
[0065] In summary, this invention achieves intelligent, efficient, and highly reliable recharge systems through the deep integration of IoT technology and water treatment technology, and has significant practical value and promising prospects for application in the fields of groundwater recharge and water resource management.
[0066] Furthermore, such as Figure 2 As shown, a water tank 2 is installed at the input end of the water inlet 1001, and a water tank inlet pipe 8 is installed on one side of the water tank 2. The water tank 2 acts as an energy storage device. By storing and releasing water, it can smooth the instantaneous pressure impact of the water inlet 1001, avoiding equipment damage or system instability caused by sudden pressure changes. When the pipeline is suddenly closed or opened, the elastic buffering capacity of the water tank 2 can absorb the shock wave generated by water hammer, protect the pipeline and valve, and extend the service life of the equipment. At the same time, the flow regulating valve of the water tank inlet pipe 8 can accurately control the water inlet of the water tank 2, realize the on-demand water supply of the water inlet 1001, and reduce energy waste.
[0067] Furthermore, such as Figure 1As shown, an electrical box 9 is fixedly installed on one side of the drain outlet 1004. The sensor module is installed inside the electrical box 9. The sensor module collects operating status data in real time and uploads the data to the Internet of Things (IoT) platform through the wireless communication module. After receiving the data from the electrical box 9, the IoT platform stores, analyzes, and visualizes the data. Through big data analysis technology, the IoT platform can explore the potential value in the data, such as load forecasting, power quality analysis, and equipment health status assessment, providing decision support for the optimized operation of the electrical system. Based on the data analysis results or user instructions, the IoT platform sends control commands to the electrical box 9, such as switch control and parameter adjustment. The control module inside the electrical box 9 receives and executes these commands to realize remote control functions.
[0068] like Figures 1-7 As shown, the principle of the IoT-based intelligent recharge system and device provided in this embodiment is as follows:
[0069] Normal reinjection process:
[0070] When the IoT platform detects through the water level gauge that the reinjection well needs water replenishment, it automatically starts the pumping process:
[0071] The reinjection pump 1002 pumps water through the inlet 1001 and the reinjection solenoid valve 3 into the storage tank 7 and the aeration tank 1. Through aeration, Fe ions and other reducing substances are fully oxidized to form large particulate precipitates.
[0072] Aerated water flows into activated carbon-manganese sand filter element 101 to remove oxidized particles, residual iron and manganese ions and odor impurities.
[0073] The IoT platform controls the opening of the reinjection solenoid valve 3, and the purified water is injected into the reinjection well through the reinjection pipeline.
[0074] After the water level gauge detects that the water level in the well has reached the standard, the platform automatically shuts off the reinjection pump 1002 and the reinjection solenoid valve 3, completing one reinjection process;
[0075] Backwashing process:
[0076] When the pressure gauge detects that the pressure drop of the activated carbon-manganese sand filter element 101 exceeds the threshold, the backwashing process is initiated:
[0077] The IoT platform closes the recharge solenoid valve 3 and opens the backwash solenoid valve 4, allowing the backwash medium, such as water, to flow back into the activated carbon-manganese sand filter element 101.
[0078] The backwashing medium flushes out the impurities trapped in the activated carbon-manganese sand filter element 101, thereby regenerating the activated carbon-manganese sand filter element 101.
[0079] After backflushing is completed, the platform closes the backflushing solenoid valve 4, restores the connection and disconnection of the reinjection pipeline 100, and the system continues to standby or execute the reinjection task.
[0080] Backup pipeline activation procedure:
[0081] When a fault occurs in the reinjection line 100 or the backflushing line 200, such as a damaged solenoid valve or a blocked line:
[0082] The IoT platform identifies faults such as abnormal pressure and sudden drop in flow through sensor data and automatically opens the backup pipeline solenoid valve 5.
[0083] The water flow is switched to the backup reinjection pipeline 100 or the backwash pipeline 200 to ensure continuous system operation;
[0084] At the same time, the platform sends a fault alarm to remind maintenance personnel to repair the main line. After the repair is completed, the system can manually or automatically switch back to the main line.
