Description

Technical Field

[0001] This utility model relates to the field of water source well control technology for renewable energy stations, and specifically to an intelligent control system for renewable water source wells. Background Technology

[0002] Water resource management faces severe challenges globally, making the efficient use of every drop of water crucial in arid regions and agricultural irrigation. Water source wells often encounter problems such as difficulty in reinjection, uneven reinjection flow from each well, and water overflow during reinjection. Without automatic control, monitoring, and alarm systems, overflows are difficult to manage promptly and effectively, ultimately causing system malfunctions and equipment damage. Traditional water source well control systems typically use wired connections, requiring extensive cabling, which is not only costly and difficult to install and maintain, but also lacks flexibility and is susceptible to environmental factors. When water source wells are far from the plant and lack nearby power, they cannot respond to real-time operating status, leading to system malfunctions and shortened equipment lifespan. Utility Model Content

The monitoring platform is used to receive data from the PLC controller and issue commands to the actuator.

[0005] Furthermore, the actuator includes a submersible pump, a valve, and a flow meter.

[0006] Furthermore, the intelligent control system also includes a control box and a power module; the transmitting gateway, wireless water immersion alarm, and wireless liquid level sensor are located outside the control box, while the receiving gateway, PLC controller, actuator, and monitoring platform are located inside the control box; the power module includes a main power supply, a solar panel, and a charging controller connected in sequence; the power module is connected to the wireless communication module and the control module respectively.

[0007] Furthermore, the wireless liquid level sensor is installed inside the water well, with a monitoring distance of up to 500 meters; the wireless water immersion alarm is installed on the ground at the wellhead, with a transmission distance of up to 5000 meters.

[0009] Furthermore, the communication protocol includes RS485 protocol, TCP / IP protocol or WLAN protocol.

[0010] Furthermore, the receiving gateway can receive multiple sets of signals simultaneously, meaning that one gateway can simultaneously receive signals from multiple wireless water leak alarms.

[0020] Example 1

[0021] like Figure 1As shown, this embodiment provides an intelligent control system for renewable water source wells, including a wireless communication module, a monitoring module, and a control module. The wireless communication module includes a receiving gateway and a transmitting gateway. The monitoring module employs non-electrical measurement technology, including a wireless water immersion alarm and a wireless liquid level sensor. The control module uses automatic control, including a PLC controller, actuators, and a monitoring platform. The PLC controller includes a wireless input interface, a central processing unit, a memory, and a wireless output interface. The wireless input interface is connected to the receiving gateway for receiving signals. The central processing unit has a built-in machine learning algorithm for processing signals. The wireless output interface is connected to the input terminal of the monitoring platform, and the output terminal of the monitoring platform is connected to the actuators for controlling the system's operating status. The actuators include submersible pumps, valves, and flow meters. The monitoring platform sends and executes signals while simultaneously having an SMS sending function.

[0022] like Figure 2 As shown, the intelligent control system also includes a control box and a power module; the transmitting gateway, wireless water immersion alarm, and wireless liquid level sensor are located outside the control box, while the receiving gateway, PLC controller, actuator, and monitoring platform are located inside the control box; the power module includes a main power supply, a solar panel, and a charging controller connected in sequence; the power module is connected to the wireless communication module and the control module respectively.

[0023] like Figure 3 As shown, this embodiment uses multiple parallel-connected water source wells. In the absence of power, a wireless level sensor, flow meter, submersible pump, and valve are installed directly in each well. A wireless water immersion alarm is installed on the ground at the wellhead. A transmitting gateway is connected to the wireless level sensor and the wireless water immersion alarm, and wirelessly transmits the reinjection water level signal to the control box via LoRa. The receiving gateway in the control box can simultaneously receive signals from multiple wireless water immersion alarms. After detecting the signal, the receiving gateway transmits it to the PLC controller via the RS485 communication protocol. The PLC controller determines the water level based on the transmitted signal and sends control signals to the actuators to start or stop the submersible pumps, and adjusts the reinjection flow of each well according to the flow meter readings.

[0024] Example 2

[0025] like Figure 4 As shown in the figure, the operating procedure of the intelligent control system for renewable water source wells in this embodiment monitors water well leakage according to the operating strategy. First, the water source well's liquid level is monitored during reinjection using a wireless liquid level sensor to determine if the liquid level is normal. If the liquid level is normal, the submersible pump operates. If the liquid level is abnormal, with water overflowing or exceeding a set value, another reinjection well is switched, and a wireless water leakage alarm sends an alarm signal. Upon receiving the signal, the control box controls the submersible pump to stop operating.

[0026] Meanwhile, when the submersible pump is running, it is also necessary to determine whether the reinjection flow of the water source well is normal. If it is normal, the system will operate normally. If an abnormality occurs, the pump frequency will be adjusted according to the flow meter to ensure that the flow of each water source well is balanced. Ultimately, this will ensure the normal reinjection flow of the water source well and the protection against water level increases and overflows, thus realizing the safe operation of the water source well through automatic control.

[0027] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
