[0002] Currently, there is a wide demand for aquatic ecological restoration. For aquatic ecological restoration water bodies mainly composed of submerged plants, the strong photosynthesis of these plants leads to a significant reduction in carbon dioxide content, oxygen supersaturation, and pH levels often exceeding 9. However, there is currently no equipment that can monitor pH while simultaneously aerating the water. Summary of the Invention

[0003] Purpose of the invention: To address the above-mentioned technical problems, this utility model provides an aeration device based on pH control; by monitoring pH and controlling aeration, the pH environment of the water body is improved, while promoting carbon sequestration by submerged plants.

[0004] Technical solution: To solve the above problems, the technical solution adopted by this utility model is as follows: A pH-controlled aeration device includes a power supply, a blower, a pH controller, a float, and a microporous aeration head. The power supply, blower, and pH controller are all mounted on the float. A pH probe is connected to the pH controller, with the probe tip extending into the water being measured. The blower is connected to the microporous aeration head. The pH controller is signal-connected to the blower. The power supply provides power to the blower, pH probe, and pH controller.

[0005] Furthermore, the power supply device includes a solar panel and a storage battery; the solar panel charges the storage battery, and the solar panel is assembled from six 550W monocrystalline silicon solar panels; the storage battery is a 51.2V, 293AH lithium iron phosphate battery, which powers the fan, pH probe, and pH controller.

[0006] Furthermore, it also includes a multi-hole adapter and an external hose; the blower is connected to the microporous aeration head in sequence through the multi-hole adapter and the external hose.

[0007] Its working principle is as follows: the pH of the water body is monitored by a pH probe, and the controller controls the blower to start aeration when the pH is greater than 8. The blower delivers air to the multi-hole adapter through the pipeline. The adapter is connected to a rubber hose (the length of the hose can be adjusted as needed). The air is introduced into the water body through the microporous aeration head to increase the carbon dioxide content in the water body and thus increase the pH of the water body.

[0008] Furthermore, the fan is a 120W fan with a maximum flow rate of 38m³ / h, and is fixed to the upper surface of the float with screws.

[0009] Furthermore, the controller is a pH controller, which can control the fan switch according to the pH set value.

[0010] Furthermore, the float is made of PVC material, with each float being 17cm high, 57cm long, and 49cm wide. Each float has a load-bearing capacity of no less than 50kg, and is composed of 6 floats, which can be connected by bayonet joints.

[0011] Furthermore, its multi-hole adapter is a five-way pagoda connector; its microporous aeration head is a microporous aeration disc; and its stainless steel support column is fixed to the upper surface of the float with screws.

[0012] Beneficial effects: Compared with existing technologies, the advantages of this utility model are: the aeration purpose is mainly to adjust the carbon dioxide content of water and remove excess oxygen from the water, thereby achieving the purpose of pH regulation.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0017] A pH-controlled aeration device includes a solar panel, a battery, a blower, a pH probe, a pH controller, a float, a microporous aeration head, a multi-hole adapter, an external hose, and a column. The solar panel and battery are the power supply units. The solar panel charges the battery, and the solar panel is composed of six 550W monocrystalline silicon solar panels. The battery is a 51.2V, 293AH lithium iron phosphate battery that powers the blower, pH probe, and pH controller.

[0018] The fan and pH controller are both mounted on the float; the column is a stainless steel bracket, and the bottom of the column is fixed to the upper surface of the float with screws; a solar panel is installed on the top of the column, and a battery is installed on the column body. The pH probe is connected to the pH controller, with its tip inserted into the water being measured. The pH controller is also connected to the fan, controlling its operation based on the set pH value. The pH controller is a pH163S controller.

[0019] The specific connection method between the pH probe and the pH163S controller is as follows: Connect the corresponding wires of the pH163S controller to the REF and INPUT ports, respectively, ensuring a secure connection to prevent looseness that could lead to unstable signal transmission.

[0020] The specific connection method between the pH163S controller and the blower is as follows: The pH163S controller has an alarm function and two normally open relay interfaces: a LO (AL) low alarm relay interface and a HI (AH) high alarm relay interface. Select one of the relay interfaces according to the actual control requirements; when the water pH value is higher than the set value, the blower can be started, so the HI (AH) interface can be selected. Connect one end of this relay interface to the corresponding port on the controller, and the other end to the corresponding signal input terminal of the blower control circuit to realize the controller's control of the blower's on / off signals. Setting the pH setpoint: This is done via the button operation instructions in the pH163S controller's user manual. Specifically: On the controller's monitoring interface, press the "Menu" button to enter the password verification interface, enter the initial password "0000" (or the modified password if already changed), and press the "Confirm" button to enter the main menu. In the main menu, find the "Alarm Setting" option (selectable via the "Down Shift" key and accessed via the "Confirm" button). In the Alarm Setting interface, set the high or low pH limit (corresponding to the pH condition for fan startup). After setting, press the "Confirm" button to save the settings and exit. When the water pH reaches or exceeds the set value (depending on the selected relay interface and setting logic), the controller will output a signal through the connected relay interface to control the fan to start; when the pH returns to the normal range, the fan will shut down according to the controller logic.

[0021] Working principle: The blower delivers air through a pipe to a multi-hole adapter, which connects to a rubber hose (the hose length can be adjusted as needed). The air is then introduced into the water through a microporous aeration head, thereby increasing the carbon dioxide content in the water and thus raising the pH of the water.

[0022] Example The following is a summary of the remediation efforts undertaken on a lake in Nanjing that is predominantly composed of submerged plants: like Figure 1As shown, the above-mentioned pH-controlled aeration equipment is selected. The solar panel is composed of 6 550W monocrystalline silicon solar panels, the battery is a 51.2V, 293AH lithium iron phosphate battery, and the fan is a common 120W fan with a maximum flow rate of 38m³ / h, which is fixed to the upper surface of the float with screws. The pH controller (pH163S controller) can control the fan switch according to the pH setting (the fan starts when the pH is greater than 8.5 and the power is turned off when the pH is less than 8). The float is made of PVC material, with a height of 17cm, length of 57cm, and width of 49cm per piece. The load-bearing capacity of a single piece is not less than 50kg. Six pieces are combined, and each piece can be connected by a bayonet. The multi-hole adapter is a five-way pagoda connector. The microporous aeration head is a microporous aeration disc (50cm in diameter). The column is a stainless steel bracket (6 evenly distributed, 1m high), which is fixed to the upper surface of the float with screws. The pH data after treatment by the equipment, as shown in the table below, are obtained through on-site experimental observation, indicating that the equipment effectively improved the pH value of the water.
