Figure 3-4As shown, when in use, the detection end below the non-contact infrared sensor 5 is the set lowest water level line, and the detection end above the non-contact infrared sensor 5 is the set highest water level line. When the floating rod 4 does not cover the detection end of the lowest water level line below the non-contact infrared sensor 5, the non-contact infrared sensor 5 sends a signal to the controller 6, so that the controller 6 controls the electromagnetic gate 16 of the water inlet pipe 15 to open, so that the liquid connected to the water inlet pipe 15 is sent to the rice-shrimp breeding area until the water level line in the rice-shrimp breeding area pushes the floating rod 4 to cover the detection end of the lowest water level line below the non-contact infrared sensor 5, so that the electromagnetic gate 16 is closed.

[0045] Working principle: When the water level regulating device for rice-shrimp farming is used, the lifting column 2 arranged at the bottom end of the limit box 1 provides support for the whole and is installed in the rice-shrimp farming area. As the bottom end of the guide rail 3 is inserted into the land surface of the rice-shrimp farming area, the floating rod 4 arranged inside the guide rail 3 floats in contact with the water surface in the farming area along with the opening on one side of the guide rail 3, and rises and falls synchronously with the water level through the floating rod 4. The non-contact infrared sensor 5 arranged at the top of the floating rod 4 realizes a preliminary judgment of the predetermined water level as the detection end is shielded by the floating rod 4. When the height of the low water level detection end of the non-contact infrared sensor 5 is not shielded by the floating rod 4, the electromagnetic gate 16 opens the water inlet pipe 15 to supply water to the breeding area. After the floating rod 4 blocks the height of the low water level detection end set by the non-contact infrared sensor 5, the electromagnetic gate 16 closes the water supply. When the height of the high water level detection end set by the non-contact infrared sensor 5 is blocked by the floating rod 4, the controller 6 receives the electrical signal to control the electric water pump impeller 7 to pump water, so that the drainage pipe 12 is provided with a corrugated telescopic tube 13 and an auxiliary pipe 14 located in the water body of the breeding area to pump water, and cooperates with the filter element 10 inside the filtering treatment box 9 to filter the water body, so as to prevent solids and suspended matter from clogging the inside of the water pump casing 8 and affecting the water level regulation processing operation, thereby increasing the overall practicality.
