A water inlet pipe 4 is connected to the middle water inlet end of the valve seat 1 at the center position between the first water outlet pipe 2 and the second water outlet pipe 3. A water inlet control valve 5 is connected to the inner side of the water inlet pipe 4. A protective shell 6 is detachably connected to the side of the valve seat 1 opposite to the water inlet pipe 4. An installation plate 7 is embedded inside the protective shell 6. A controller 8 is fixedly installed on the surface of the installation plate 7. The signal input terminal of the drive motor 9 is connected to the signal output terminal of the controller 8 to facilitate the response and start of the drive motor 9. The transmission hexagonal column 31 is meshed with the drive gear 11 through an emergency drive gear. After the waterproof plug 30 is opened, the transmission hexagonal column 31 is directly exposed. The transmission hexagonal column 31 is rotated by the handle of the internal hexagonal sleeve, which in turn drives the drive gear 11 to rotate. In case of failure, the ball valve can be opened manually in an emergency. The drive motor 9 is fixedly installed on the surface of the installation plate 7 at the top position of the controller 8. A limit plate 13 is fixedly installed on the inner end face of the protective shell 6. The output shaft end of the drive motor 9 is connected to the transmission gear 10. The bottom of the transmission gear 10 is meshed with the drive gear 11. The middle of the drive gear 11 is fixedly installed with the transmission shaft 12. The end of the drive shaft 12 is connected to the connecting shaft 15 located inside the valve seat 1. The end of the connecting shaft 15 is connected to the ball core 16 located inside the valve seat 1. The end faces of the drive gear 10 and the drive gear 11 are in contact with the limiting plate 13. The drive gear 10 drives the drive gear 11 and the drive shaft 12 to rotate. A rotating bushing is embedded in the inner side of the valve seat 1. The connecting shaft 15 rotates in the rotating bushing. The transmission shaft 12 and the connecting shaft 15 are connected by a keying fit, which facilitates the rotation of the transmission shaft 12 by the transmission gear 10 and the drive gear 11, thereby facilitating the synchronous rotation of the connecting shaft 15. This enables more flexible and convenient rotation of the ball core 16. The center of the ball core 16 is provided with a water inlet channel 17. A horizontal channel 18 is provided in the ball core 16 at a position corresponding to the center of the first water outlet pipe 2 and the second water outlet pipe 3. A first vertical channel 19 is provided at the bottom of the inner middle part of the ball core 16 in a direction perpendicular to the horizontal channel 18. A second vertical channel 20 is provided at the top of the inner middle part of the ball core 16 in a direction perpendicular to the horizontal channel 18.

The position of the inlet channel 17 corresponds to the inlet connecting hole 21, and the inlet channel 17 is connected to the inlet connecting hole 21. The horizontal channel 18 does not penetrate the ball core 16. The first vertical channel 19 and the second vertical channel 20 penetrate the ball core 16. After the horizontal channel 18 rotates to a position corresponding to the center of the first water outlet pipe 2 and the second water outlet pipe 3, it connects to either the first water outlet pipe 2 or the second water outlet pipe 3. After the first vertical channel 19 and the second vertical channel 20 rotate to a position corresponding to the center of the first water outlet pipe 2 and the second water outlet pipe 3, they connect to the first water outlet pipe 2 and the second water outlet pipe 3 respectively. This allows the position and angle of the internal water inlet channel 17, the horizontal channel 18, the first vertical channel 19, and the second vertical channel 20 to be adjusted by rotating the ball core 16. This also allows for selective control of either the first water outlet pipe 2 or the second water outlet pipe 3, and facilitates communication between the first vertical channel 19 and the second vertical channel 20 and the first water outlet pipe 2 and the second water outlet pipe 3 respectively. This enables the water entering the water inlet pipe 4 to be quickly distributed and delivered to the first water outlet pipe 2 and the second water outlet pipe 3, facilitating irrigation at different irrigation points.

[0019] The outer side of the valve seat 1 is provided with multiple sets of connecting arms 25. The end of the protective shell 6 is provided with mounting seats 26 corresponding to the connecting arms 25. The protective shell 6 and the valve seat 1 are connected by the connecting arms 25 and the mounting seats 26. The outer side of the valve seat 1 is connected with a support plate 27 between the two connecting arms 25. The positions of the connecting arms 25 and the mounting seats 26 are corresponding, and the connecting arms 25 and the mounting seats 26 are fixedly connected by locking bolts. The support plate 27 is used to reinforce the two connecting arms 25. The connecting arms 25, the mounting seats 26 and the support plate 27 facilitate the combination and connection between the protective shell 6 and the valve seat 1, making the protective shell 6 easy to disassemble and thus facilitating the maintenance of its internal structure. At the same time, the support plate 27 ensures the stability of the connection.

[0020] The four corners of the limiting plate 13 are provided with inner spacers 28, which separate the mounting plate 7 and the limiting plate 13. The mounting plate 7 and the limiting plate 13 are connected by an inner spacer 28 and a connecting pin 29. The connecting pin 29 passes through the mounting plate 7 and is inserted into the inner spacer 28. The mounting plate 7 and the limiting plate 13 facilitate the arrangement and installation of the drive mechanism. The inner spacer 28 and the connecting pin 29 facilitate the connection between them, ensure the stability of the installation, and facilitate the subsequent disassembly and maintenance of individual components.

[0021] like Figure 8 As shown, the intelligent irrigation method of this embodiment includes the following steps: Step 1: Collect multidimensional status data; Step two: Analyze irrigation needs based on data; Step 3: Generate irrigation control instructions; Step four: The ball valve initiates the irrigation process.

[0022] Step one includes collecting plant status data and environmental status data. The plant status data includes soil moisture, crop transpiration, and leaf water content. When obtaining soil moisture, high-precision capacitive soil moisture sensors are buried in different areas of the cotton field to monitor and obtain the volumetric water content of the soil in real time. The soil moisture sensors must be evenly distributed at the specified intervals, and the depth of the soil moisture sensors must be sufficient to cover the main root distribution layer. Crop transpiration is measured by stem flow meter to measure the sap flow velocity in the trunk, reflecting the transpiration rate of the crop. Leaf water content is indirectly reflected by the stem contraction rate through the installation of leaf temperature sensor and stem diameter sensor on a typical plant. When acquiring environmental status data, small weather stations are set up in the field to collect air temperature, relative humidity, light intensity, wind speed and rainfall. After the plant status data and environmental status data are collected, the data need to be calibrated and denoised to provide accurate data support for subsequent irrigation demand analysis. Step 2: Based on the collected and processed multi-source data, combined with the cotton growth cycle and water requirement patterns, calculate the cotton water requirement and output precise irrigation decisions; When calculating the water requirement of cotton, it is necessary to determine the effective soil moisture, calculate the crop water deficit index, and predict the water requirement. When determining the effective soil moisture, the effective water reserve is obtained by calculating the current soil moisture. When calculating the crop water deficit index, it is necessary to combine transpiration and effective precipitation. The calculation formula is: Water Deficit Index = (Evapotranspiration - Effective Precipitation) / (Evapotranspiration). When evapotranspiration is greater than effective precipitation, it indicates that the crop is short of water. When predicting water demand, it is necessary to use machine learning models based on weather forecasts and historical water use data to predict crop water demand in the next 7 days, specifically choosing an LSTM neural network. Step 3: When generating instructions, a safety threshold needs to be set. The target soil moisture threshold needs to be adjusted according to different growth stages of cotton, as follows: During the seedling stage, water requirements are low, and the target humidity is 60%-70% of field capacity. During the budding stage, water requirements gradually increase, with a target humidity of 70%-80% of field capacity. During the flowering and boll-forming stage, water demand is at its peak, with a target humidity of 80%-90% of field capacity. During the boll-opening stage, water requirement decreases: the target humidity is 65%-75% of field capacity. When the effective humidity is less than the safety threshold, irrigation demand needs to be triggered and irrigation control instructions need to be generated. Step 4: After generating irrigation control instructions based on the water requirements of the plants, the irrigation control instructions are sent to the controller 8. The controller 8 controls the inlet control valve 5 and the drive motor 9 to respond. The inlet control valve 5 allows water to enter the inlet pipe 4, while the drive motor 9 drives the transmission shaft 12 and the connecting shaft 15 to rotate, so that the ball core 16 rotates at different angles within the valve seat 1. By rotating the ball core 16 within the valve seat 1, the first water outlet pipe 2 and the second water outlet pipe 3 can be opened individually or simultaneously, and water can be transported for irrigation through the first water outlet pipe 2 and the second water outlet pipe 3.

[0023] The working principle and usage process of this utility model: In actual application, the intelligent ball valve for farmland irrigation first obtains the cotton growth status and environmental parameters in real time and accurately through multiple monitoring devices deployed on the cotton field. Combining the cotton growth characteristics and environmental dynamics, the water demand of the cotton is determined and converted into irrigation control commands. The controller 8 receives the irrigation control commands and then controls the inlet control valve 5 and the drive motor 9 to respond. The inlet control valve 5 controls the opening of the inlet pipe 4, allowing water to enter the inlet pipe 4. After the drive motor 9 starts responding, the drive motor 9 drives the transmission gear 10 to rotate, the transmission gear 10 drives the drive gear 11 to rotate, and then the meshing connection of the transmission gear 10 and the drive gear 11 drives the transmission shaft 12 to rotate, thereby driving the connecting shaft 15 to rotate synchronously, and finally the connecting shaft 15 drives the ball core 16 in the valve seat 1 to rotate in position, thereby realizing water supply regulation. During the specific control process, after the ball core 16 rotates inside the valve seat 1, the position and angle of its internal water inlet channel 17, horizontal channel 18, first vertical channel 19 and second vertical channel 20 are adjusted by the rotation of the ball core 16. After the horizontal channel 18 rotates to a position corresponding to the center of the first water outlet pipe 2 and the second water outlet pipe 3, the horizontal channel 18 can be selectively connected to the first water outlet pipe 2 and the second water outlet pipe 3, so as to facilitate selective control of the first water outlet pipe 2 and the second water outlet pipe 3. By rotating the first vertical channel 19 and the second vertical channel 20 to positions corresponding to the centers of the first water outlet pipe 2 and the second water outlet pipe 3, the first vertical channel 19 and the second vertical channel 20 are connected to the first water outlet pipe 2 and the second water outlet pipe 3, respectively. This allows water to be quickly distributed and delivered to the first water outlet pipe 2 and the second water outlet pipe 3 after entering the water inlet pipe 4. This facilitates irrigation at different irrigation points, ensures irrigation accuracy, realizes the automation and intelligence of irrigation, and guarantees the water supply during the key growth period of cotton. In emergency use, open the waterproof plug 30 to expose the transmission hexagonal column 31 directly. Use the internal hexagonal sleeve handle to rotate the transmission hexagonal column 31, which in turn drives the emergency drive gear to rotate. The emergency drive gear then drives the drive gear 11 to rotate, thus enabling the ball valve to be opened manually in case of a malfunction for emergency use. Furthermore, the drive motor 9, transmission gear 10, drive gear 11, and transmission shaft 12 are arranged and installed using the mounting plate 7 and the limiting plate 13. The inner spacer 28 and connecting pin 29 facilitate the connection between them while ensuring the stability of the installation. They also facilitate the subsequent disassembly and maintenance of individual components. In addition, the protective shell 6 and valve seat 1 are connected by the connecting arm 25, mounting base 26, and support plate 27, making the protective shell 6 easy to install and disassemble, ensuring a stable connection, and facilitating the maintenance of its internal structure. At the same time, the support plate 27 ensures the stability of the connection between them.
