Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a real-time water quality monitoring device for farmland irrigation. Background Technology

[0002] In the development of modern agriculture, farmland irrigation is a key link in ensuring the healthy growth of crops and achieving high and stable yields. High-quality irrigation water plays a vital role in the growth and development of crops, yield and quality, as well as the stability of the soil ecological environment. However, with the rapid advancement of industrialization and urbanization, as well as the development and changes in agricultural production itself, farmland irrigation water quality faces many challenges.

[0003] When existing water quality monitoring systems monitor irrigation water for farmland, the roots of plants in the irrigation water can affect the monitoring end, leading to deviations in the monitoring data.

[0004] An existing patent (publication number: CN220040416U) discloses a water quality monitoring device, relating to the field of farmland irrigation technology. It includes an installation rod and an anti-clogging component. A monitoring instrument is installed in the middle of the installation rod. The anti-clogging component, used to prevent objects from clogging the monitoring end, is located at the lower end of the installation rod. The anti-clogging component includes a strainer net, a monitoring tube, a rotating rod, and a cleaning rod. The monitoring tube is installed inside the strainer net, and the rotating rod is installed in the middle of the strainer net. The cleaning rod is installed at the lower end of the rotating rod. A wire hole is provided on the surface of the installation rod. This water quality monitoring device uses the strainer net to provide external protection for the monitoring tube of the monitoring instrument, preventing plant roots and other objects in the irrigation water from affecting the monitoring tube and improving the accuracy of the monitoring data. A motor, powered by a solar panel, is connected to the top of the rotating rod. The rotation of the rotating rod causes the cleaning rod to rotate outside the strainer net, cleaning roots and other objects and preventing clogging.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing water quality monitoring devices lack a structure that provides warnings when monitoring water quality. As a result, when water quality abnormalities occur, staff cannot promptly learn of the changes in water quality and therefore cannot take timely measures to ensure the safety of irrigation water for farmland.

[0006] To address this, a real-time water quality monitoring device for farmland irrigation is proposed. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A real-time water quality monitoring device for farmland irrigation includes a guiding mechanism 1, and a monitoring mechanism 2 is fixedly connected to the right side of the inner side of the guiding mechanism 1.

[0029] The monitoring mechanism 2 includes a protective shell 21, a water quality sensor 22, a microcontroller 23, and an alarm 24. The protective shell 21 is fixedly connected to the right side of the inside of the guide mechanism 1. The water quality sensor 22 is fixedly connected to the inside of the protective shell 21. The detection end of the water quality sensor 22 extends through the protective shell 21 to the inside of the guide mechanism 1. The microcontroller 23 is fixedly connected to the front of the guide mechanism 1. The alarm 24 is fixedly connected to the right side of the guide mechanism 1.

[0030] In this embodiment: the protective shell 21 provides physical protection for the internal water quality sensor 22, preventing damage from external factors such as collisions, friction, and corrosion, thereby ensuring the stable and reliable operation of the water quality sensor 22 and extending its service life. The water quality sensor 22 detects water quality parameters in real time within the water storage plate 13, accurately acquiring various components and indicators in the water, such as pH, conductivity, and dissolved oxygen, providing crucial data for judging the quality of irrigation water and enabling real-time monitoring of farmland irrigation water quality. The microcontroller 23 receives the detection data transmitted from the water quality sensor 22, analyzes, processes, and compares this data, and determines whether the water quality meets the requirements for farmland irrigation through preset standards and algorithms. Once an abnormality in water quality is detected, it can promptly issue a command to control the alarm 24 to sound an alarm, realizing intelligent monitoring and management of water quality. Under the control of the microcontroller 23, when an abnormality in water quality occurs, the alarm 24 can promptly issue obvious alarm signals such as sound and light to attract the attention of relevant personnel and remind them to take timely measures.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the guide mechanism 1 includes a guide shell 11, a lower inclined plate 12, a water storage plate 13, a drain pipe 14, a solenoid valve 15, and a connecting pipe 16. The guide shell 11 is fixedly connected to the top of the water storage plate 13, the microcontroller 23 is fixedly connected to the front side of the guide shell 11, and the alarm 24 is fixedly connected to the right side of the guide shell 11.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, the lower inclined plate 12 is fixedly connected to the bottom of the inner side of the guide shell 11, the water storage plate 13 is fixedly connected to the bottom of the guide shell 11, the protective shell 21 is fixedly connected to the right side of the inner side of the water storage plate 13, and the detection end of the water quality sensor 22 extends through the protective shell 21 to the inner side of the water storage plate 13.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, the drain pipe 14 is fixedly connected to the left side of the rear side of the lower inclined plate 12, the solenoid valve 15 is fixedly connected to the bottom of the drain pipe 14, and the connecting pipe 16 is fixedly connected to the bottom of the solenoid valve 15.

[0034] In this embodiment: the guide shell 11 guides and converges the water flow entering the device, allowing the water to flow along the designed path and concentrate on the water storage plate 13. This ensures that the water quality sensor 22 can detect representative water samples. At the same time, it supports and limits the microcontroller 23, alarm 24, lower inclined plate 12, and water storage plate 13. The inclined structure of the lower inclined plate 12 facilitates the rapid flow and convergence of the water, allowing the water to flow smoothly from the guide shell 11 to the water storage plate 13. The water storage plate 13 stores a certain amount of water, providing a relatively stable detection environment for the water quality sensor 22. In this environment, the water quality sensor 22 can detect water quality parameters more accurately. The drain pipe 14 discharges the water inside the water storage plate 13 to the solenoid valve 15. The solenoid valve 15, controlled by the microcontroller 23, controls the opening and closing of the drain pipe 14. The connecting pipe 16 is used to connect to external irrigation equipment, allowing the discharged water to flow smoothly to the designated location.

[0035] Specifically, such as Figure 5 As shown, support columns 3 are fixedly connected to both sides of the bottom of the guide shell 11, and the bottom of the support columns 3 is engraved with anti-slip texture.

[0036] Specifically, such as Figure 5 As shown, limit tubes 4 are fixedly connected to both sides of the guide shell 11, and a grounding rod 5 is slidably connected to the inner side of the limit tube 4. The bottom of the grounding rod 5 is tapered.

[0037] In this embodiment: by setting the support column 3, the guide shell 11 can be stably supported on the ground, so that the device can maintain balance during operation. By setting the anti-slip texture, the friction between the support column 3 and the ground is increased, which further improves the stability of the device. By setting the limiting tube 4, the ground insertion rod 5 can be supported and limited. By setting the ground insertion rod 5, the device can be firmly fixed in the farmland, preventing the device from deviating from its original position due to external pulling or movement. By setting the bottom of the ground insertion rod 5 to be conical, it is easier to insert into the loose soil.

[0038] Specifically, such as Figure 1 As shown, a left inclined plate 6 is fixedly connected to the bottom of the inner side of the water storage plate 13, and the surface of the left inclined plate 6 is coated with anti-corrosion paint.

[0039] Specifically, such as Figure 1As shown, a filter plate 7 is fixedly connected to the top of the inner side of the guide shell 11, and the surface of the filter plate 7 is coated with an anti-corrosion coating.

[0040] In this embodiment: by setting the left inclined plate 6, the water flow can be guided to one side of the water quality sensor 22, so that the water in the water storage plate 13 can be more effectively collected in one place, which is convenient for the water quality sensor 22 to detect. By setting the anti-corrosion coating, it can effectively resist the corrosion of various chemicals in the water and protect the structure of the left inclined plate 6 from damage. By setting the filter plate 7, larger impurities in the water, such as leaves, weeds, and silt, can be intercepted, preventing these impurities from entering the water storage plate 13 and affecting the normal operation of the water quality sensor 22. By setting the anti-corrosion coating, the filter plate 7 can be prevented from being corroded by chemicals in the water, maintaining the effectiveness of its filtration function.

[0041] Working principle: First, the user moves the guide shell 11 to the designated work area and supports the entire device on the ground using the support column 3. Next, the user slides the ground insertion rod 5 out from the inside of the limiting tube 4 and inserts it into the soil. Then, the user connects the connecting pipe 16 to the irrigation equipment of the farmland. After the connection is completed, the user powers on and activates the microcontroller 23, water quality sensor 22, and alarm 24. At this time, the user pours the water to be irrigated from the top of the guide shell 11, and the water flows through the filter plate 7. The filter plate 7 blocks larger impurities in the water, such as leaves, weeds, and silt. The filtered water flows downwards along the guide plate 12 into the inner side of the water storage plate 13. When the water flows into the left inclined plate 6 at the bottom of the inner side of the water storage plate 13, the inclined plate 6 guides the water flow to the detection end of the water quality sensor 22. Once the water quality sensor 22 comes into contact with the water flow, it immediately begins to work, monitoring various water quality indicators in real time. If the detection results show that the water quality meets the requirements for farmland irrigation, the water flow will... The water is discharged through the drain pipe 14 from the storage plate 13, then flows through the solenoid valve 15 and the connecting pipe 16, and finally flows into the irrigation equipment for normal irrigation of the farmland. Conversely, when the water quality sensor 22 detects that the water quality does not meet the requirements, it will immediately send a signal to the microcontroller 23. After receiving the signal, the microcontroller 23 will react quickly and control the solenoid valve 15 to close, preventing the substandard irrigation water from flowing into the farmland and avoiding damage to crops. At the same time, the microcontroller 23 will also control the alarm 24 to emit a loud alarm sound to attract the user's attention and prompt the user to deal with the substandard irrigation water in time. Finally, after the user has treated the irrigation water, the water quality sensor 22 will continue to monitor the water quality. Once it detects that the water quality has returned to normal, it will transmit a signal to the microcontroller 23. The microcontroller 23 will then control the alarm 24 to stop emitting the alarm sound and reopen the solenoid valve 15, so that the treated and qualified irrigation water can flow smoothly to the irrigation equipment to continue to provide irrigation services for the farmland.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
