[0064] The present application replaces the traditional water level detection sensor with a water level monitoring structure that can display colors, uses the color displayed by the measuring component 2 to judge the water level, and monitors the water level while reducing the use of sensors, which can reduce the cost of the entire automated irrigation. At the same time, using a mechanical structure to measure the water level of the paddy field can improve the reliability of water level monitoring in the automated irrigation system and make it easier to adapt to complex field environments.

[0068] The mounting bracket 1 is nailed into the paddy field through the ground anchor rod 12, so that the mounting bracket 1 has good stability in subsequent use.

[0069] Embodiment 2

[0070] As one of the embodiments of this technical solution, Figure 2 As shown, the measuring component 2 includes a separation cylinder 21, which is fixed to the side wall of the inner ring of the mounting ring 11 through a connecting rod. A floating platform 22 is arranged inside the separation cylinder 21. The floating platform 22 may be hollow. A gas with a density lower than that of air is filled in the cavity of the floating platform 22 to increase the buoyancy of the floating platform 22, thereby providing a structural basis for driving the operation of the marking component 3. At least two vertically distributed guide rods 23 are inserted on the floating platform 22, and the guide rods 23 are fixed to the inner wall of the separation cylinder 21. A plurality of evenly distributed through holes are opened on the surface of the separation cylinder 21.

[0071] The lifting rod 24 has its bottom end fixed at the center of the top of the floating platform 22 , and its top end passes through the top side wall of the partition cylinder 21 and is connected to the marking component 3 .

[0072] When installing the measuring component 2, an installation hole is excavated at a pre-selected position, and the installation bracket 1 is nailed around the installation hole so that the bottom end of the separation tube 21 extends into the installation hole. The area where the separation tube 21 extends accounts for at least one-fifth of the total length of the separation tube 21.

[0075] As one of the embodiments of this technical solution, Figure 3 and 7 As shown, the identification component 3 includes an identification plate 31 arranged vertically, the identification plate 31 is divided into at least three identification areas from top to bottom, and each identification area is coated with a color, the color types between the identification areas are different, the identification area is a rectangular structure, the water level represented by the color from top to bottom of the identification plate 31 is from low to high, and a certain range of water level values ​​are marked by the identification area of ​​the rectangular structure, and the height of the identification area represents the specific range of the water level interval, because the amount of water required by rice in different periods is different, and the required amount of water can be within a certain range. Through the above identification method, the monitoring cost can be reduced;

[0083] The grid plate 311 can enhance positioning accuracy and reduce reflections and shadows, and can adapt to complex backgrounds. In complex or changing backgrounds, the grid structure can effectively isolate color areas, allowing the recognition module to focus on the color information within the grid without being disturbed by the background. This is especially helpful for color recognition in the wild and dynamic environments, reducing the difficulty of the recognition module in recognizing colors, thereby lowering the standards for specific recognition equipment and reducing costs.

[0084] The grid plate 311 itself is light in color, such as gray or light yellow.

[0085] Embodiment 4

[0087] The bearing shell 41 and the partition plate are both provided with through grooves, and the through grooves are covered with a partition net 44 . The partition net 44 only separates the filter material and the gravel, and does not filter impurities such as impurities and sludge.

[0088] The coarse filter layer 42 and the fine filter layer 43 filter and block the debris and silt in the paddy field to prevent them from entering the separation cylinder 21 and affecting the lifting and lowering of the floating platform 22 .

[0089] Embodiment 5

[0090] As one of the embodiments of this technical solution, Figure 4 and 5 As shown, it also includes a pressing component 5 to prevent the identification plate 31 from being driven by wind, and there are two pressing components 5, and the two pressing components 5 are symmetrically arranged on both sides of the outer shell 32;

[0091] The pressing assembly 5 comprises a bearing plate 51, a slanted plate 52 arranged to be tilted upward is fixed to one side of the bearing plate 51, and a curved plate 53 is further provided on one side of the slanted plate 52, the curved plate 53 is bent upward, and the curved plate 53 is connected to the slanted plate 52;

[0092] The bearing plate 51 is connected to the base 55 via a connecting column 54 at its bottom end, and the base 55 is connected to the identification plate 31 via a sliding connecting rod, which passes through the side wall of the outer shell 32 through a sliding through groove on the side wall of the outer shell 32.

[0093] A guide member 56 is also provided on the pressing assembly 5. The connecting column 54 is rotatably connected to the base 55, that is, the connecting column 54 can rotate.

[0094] When the wind blows, the guide member 56 is used to ensure that the bearing plate 51, the inclined plate 52 and the curved plate 53 are always facing the wind direction. When the wind blows to the inclined plate 52 and the curved plate 53, downward pressure is formed to press down the identification plate 31, so as to prevent the identification plate 31 from floating up due to the wind and affecting the water level monitoring. At the same time, since the floating platform 22 has a large buoyancy, the floating platform 22 will not be completely pressed into the water, thereby not affecting the water level monitoring.
