Description

Technical fields:

[0001] This utility model relates to a water quality sampling and testing device for farmland irrigation. Background technology:

[0002] In the daily production process of farmland, farmland irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply crops with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient rainfall or uneven distribution. Therefore, it is necessary to carry out artificial irrigation to make up for the lack of natural rainfall.

[0003] Before irrigating farmland, the water quality of the irrigation water needs to be tested to ensure that the water quality meets the requirements. However, most existing testing devices collect irrigation water and then conduct external water quality testing, which takes too long and has low feedback efficiency, and cannot obtain accurate water quality test results at the irrigation site. Utility model content:

[0004] This utility model provides a water quality sampling and testing device for farmland irrigation. It features a reasonable structural design, integrated control based on a controller, and various functional components and electrical elements. It can be directly connected to water pipelines and uses built-in multi-type sensors for detection. This allows for rapid and accurate acquisition of irrigation water source test results before irrigation, improving the overall efficiency of water quality testing. Simultaneously, it can visually display whether the irrigation water source meets quality standards, thereby ensuring the normal growth of crops in the farmland and solving the problems existing in the prior art.

[0026] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0027] like Figure 1-7 As shown, a water quality sampling and testing device for farmland irrigation is provided, the device comprising:

[0028] The housing 1 has two parallel detection channels inside it. Each detection channel has an interface at both ends for connecting to a water supply pipe to detect the water quality of the irrigation water source. The detection channels are independent and not interconnected.

[0029] Each detection channel is equipped with a detection component 3, which is arranged in a ring on the inner wall of the detection channel to detect the irrigation water entering the detection channel. The detection component includes a flow sensor, a temperature sensor and a pH sensor. A solenoid valve 2 is provided on the end of the housing near the farmland. The solenoid valve 2 is used to control the flow of irrigation water to ensure that qualified irrigation water enters the farmland.

[0030] The housing is equipped with a display component configured with the detection component, which is used to display whether the irrigation water quality is qualified; a controller is provided inside the housing, which is connected to the detection component through an AD converter, connected to a solenoid valve through a driver, and connected to the display component through a trigger.

[0031] The pH sensor, temperature sensor, and flow sensor are arranged in a ring from the inside out within the detection path.

[0032] The display component includes a red indicator light 4 and a green indicator light 5.

[0033] An insulation layer is provided on the outside of the shell.

[0034] The controller is an STM32F103C8T6 with 64 pins. The controller is connected to the AD converter via pin 15, to the trigger via pins 33 and 34, and to the driver via pin 38.

[0035] The AD converter is model AD8551 and has 8 pins. The AD converter is connected to pin 15 of the controller through pin 6 and to the detection component through pin 3.

[0036] The trigger is model FDS9945. Pin 2 of the trigger is connected to pin 34 of the controller, and pin 3 of the trigger is connected to pin 33 of the controller. Green indicator light and red indicator light are connected to pin 5 and pin 8 of the trigger.

[0037] The driver is model ULN2003 and has 16 pins. The driver is connected to pin 38 of the controller via pin 1. A first relay is connected to pin 16 of the driver. A first resistor and a first diode are connected in parallel on the first relay. A drive interface is provided on the first relay.

[0038] The working principle of a water quality sampling and testing device for farmland irrigation in this embodiment of the present invention is as follows: Based on the integrated control function of the controller, and in conjunction with various types of functional components and electrical components, it can be directly connected to the water supply pipeline. It uses built-in multi-type sensors for detection, and can quickly and accurately obtain the detection results of irrigation water source before irrigation, thereby improving the overall efficiency of water quality detection. At the same time, it can intuitively display the qualified irrigation water source, thereby ensuring the normal growth of crops in the farmland. Compared with the detection methods in the prior art, it can combine the detection link and the irrigation link, simplifying the actual detection process.

[0039] The overall solution mainly includes a housing 1, inside which are two parallel detection channels. Each detection channel has an interface at both ends for connecting to a water supply pipe to detect the water quality of the irrigation water source. The detection channels are independent and not interconnected. Each detection channel contains a detection component 3, which is arranged in a ring on the inner wall of the detection channel to detect the irrigation water entering the channel. The detection component includes a flow sensor, a temperature sensor, and a pH sensor. A solenoid valve 2 is located on the end of the housing near the farmland. The solenoid valve 2 is used to control the flow of irrigation water to ensure that qualified irrigation water enters the farmland. A display component is located on the housing and is configured with the detection components. The display component is used to show whether the irrigation water quality is qualified. A controller is located inside the housing. The controller is connected to the detection components through an AD converter, the controller is connected to the solenoid valve through a driver, and the controller is connected to the display component through a trigger.

[0040] Since water quality testing requirements are not particularly high during farmland irrigation, multiple aspects such as pH value, temperature, and flow rate can be tested. Generally speaking, when the quality of irrigation water source is unqualified, the above three parameters will fluctuate significantly. Therefore, this application can complete accurate water quality testing by using multiple corresponding sensors during the testing process.

[0041] The type of sensor can be flexibly set and adjusted according to the type of crop and irrigation growth requirements, as long as the specific requirements of power change and electrical load are met.

[0042] The pH sensor, temperature sensor, and flow sensor in this application are arranged in a ring from the inside to the outside within the detection path. Their specific detection positions are set according to the functionality of the sensors in order to obtain more accurate detection data.

[0043] During actual testing, the two water supply pipes are connected to the two ports of the detection channel respectively. At this time, the solenoid valve is in the closed state, and the irrigation water enters the two detection channels from the end away from the farmland. The pH sensor, temperature sensor and flow sensor start to work to detect multiple parameters of the irrigation water and transmit them to the controller. The controller compares the detection data with the set threshold range.

[0044] When the detected parameters are within the threshold range, it indicates that the irrigation water quality meets the irrigation requirements and is considered qualified water quality. The controller illuminates the green indicator light through the trigger and transmits a relay signal to the solenoid valve through the driver, opening the solenoid valve to irrigate the farmland. When any detected parameter is outside the threshold range, the red indicator light will illuminate, and the solenoid valve will be closed to prevent unqualified irrigation water from entering the farmland.

[0045] The core component of this application is a controller, model STM32F103C8T6, which has 64 pins. The controller is connected to the AD converter through pin 15, to the trigger through pins 33 and 34, and to the driver through pin 38, forming the overall hardware circuit. The detection and irrigation of irrigation water are achieved by relying on the above overall hardware circuit.

[0046] To further improve detection accuracy, an insulation layer is installed on the outside of the housing to reduce the impact of external conditions on the detection results.

[0047] Preferably, the AD converter is model AD8551, which has 8 pins. The AD converter is connected to pin 15 of the controller through pin 6, and the AD converter is connected to the detection component through pin 3. The AD converter converts the sensor signal into a signal type that the controller can accurately recognize, thus avoiding misidentification.

[0048] Preferably, the trigger is model FDS9945. Pin 2 of the trigger is connected to pin 34 of the controller, and pin 3 of the trigger is connected to pin 33 of the controller. Green and red indicator lights are connected to pins 5 and 8 of the trigger, which can quickly trigger and light up the corresponding indicator lights when a detection result is obtained.

[0049] Preferably, the driver is model ULN2003, which has 16 pins. The driver is connected to pin 38 of the controller through pin 1. A first relay is connected to pin 16 of the driver. A first resistor and a first diode are connected in parallel on the first relay. The first relay has a drive interface that can be connected to a solenoid valve to ensure that the solenoid valve responds quickly when opening or closing.

[0050] It should be noted that the detection channel interface used in this application is a conventional interface set in the prior art, which can be adapted to the water supply pipeline, and will not be described in detail in this application.

[0051] In summary, the water quality sampling and testing device for farmland irrigation in this embodiment of the present invention, based on the integrated control function of the controller and in conjunction with various types of functional components and electrical elements, can be directly connected to the water supply pipeline. It uses built-in multi-type sensors for detection, which can quickly and accurately obtain the detection results of irrigation water sources before irrigation, improving the overall efficiency of water quality testing. At the same time, it can intuitively display the qualified irrigation water sources, thereby ensuring the normal growth of crops in farmland. Compared with the detection methods in the prior art, it can combine the detection and irrigation processes, simplifying the actual detection process.

[0052] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
