Description

Technical Field

[0001] This invention relates to the field of farmland irrigation equipment technology, specifically to a zoned pressure regulating device for farmland irrigation pipeline networks. Background Technology

[0002] With the development of modern agriculture, farmland irrigation has gradually shifted from traditional flood irrigation to water-saving irrigation methods such as drip irrigation, sprinkler irrigation, and micro-sprinkler irrigation. To meet the irrigation needs of different crops, different growth stages, and different planting areas, farmland irrigation systems typically adopt a network structure combining main pipes, branch pipes, and zoned irrigation. Water pumps deliver irrigation water to each irrigated area to improve water resource utilization efficiency and crop yield. Therefore, the rational control of the total irrigation water volume directly affects irrigation effectiveness, water-saving performance, and the operational stability of the entire irrigation system.

[0003] For example, Chinese patent CN111213571A discloses an irrigation pipe for farmland irrigation. In this component, a support plate is fixedly connected to the bottom of the curved pipe surface, and a counterweight is fixedly connected to the bottom of the support plate. A connecting plate is fixedly connected to the bottom of the support plate by bolts, and support legs are fixedly connected to both sides of the bottom of the connecting plate. A fixing frame is fixedly connected to the left end of the curved pipe. This invention relates to the field of irrigation pipe technology. In this irrigation pipe for farmland irrigation, one end of the curved pipe inlet is horizontal, and the counterweight makes the bottom of the curved pipe face downwards, allowing the support legs to touch the bottom and supporting the pipe inlet to prevent it from sinking into the sludge. The filter frame inside the fixing frame can filter out impurities in the water, preventing impurities from entering the external water pump and affecting its normal operation. Pulling the pull ring disengages the first locking block from the slot, allowing the filter frame to be pulled out of the fixing frame for cleaning or replacement. The operation is convenient and improves practicality. However, in practical application, the irrigation water volume in farmland irrigation is mostly controlled by manually adjusting the valve opening or starting and stopping the water pump. When it is necessary to adjust the total amount of irrigation water according to the farmland area, soil moisture or crop growth stage, it is easy to cause excessive irrigation water, resulting in water waste, soil water accumulation and insufficient irrigation of crops. To solve the above problems, we propose a zoned pressure regulation device for farmland irrigation pipeline network. Summary of the Invention

[0008] Preferably, a connecting rod is fixedly connected to the bottom surface of the rotating rod, and a water turbine blade is rotatably installed inside the fixed tube, with the top end of the water turbine blade fixedly connected to the bottom surface of the connecting rod.

[0013] In summary, the present invention has the following main beneficial effects: By setting up delivery pipes, irrigation water is first delivered into the delivery pipes, and then sent into the water supply pipes through connecting components. The water flow area inside each water supply pipe is adjusted by water control components to regulate the irrigation water volume in different zones. Subsequently, the irrigation water is sprayed onto the farmland through sprinkler pipes and nozzles. At the same time, pressure reducing valves can reduce the water pressure entering the sprinkler pipes, keeping the nozzles spraying stably. This allows for flexible adjustment of the total irrigation water volume according to different farmland areas, soil moisture, and crop growth stages, avoiding excessive irrigation that wastes water resources or insufficient irrigation that affects crop growth. In addition, the pressure reducing valves can control the water pressure inside the sprinkler pipes according to the local irrigation volume, thereby improving irrigation uniformity and efficiency. By setting up water impeller blades, when irrigation water flows through the fixed pipe, the water flow drives the water impeller blades to rotate, causing the connecting rod to synchronously drive the rotating rod to rotate, thereby enabling the main gear to rotate synchronously according to the water flow state. This utilizes the power of the water flow to drive the main gear to rotate automatically, making it easier to adjust the flow rate inside the water delivery pipe according to the water supply status, reducing frequent manual adjustments and improving the automation level of irrigation water volume regulation. By setting up a rotating ball, when the rotating ball is rotating, the water delivery holes on the outer wall of the rotating ball can form different communication areas with the inside of the water delivery pipe, thereby adjusting the water flow rate inside the water delivery pipe. At the same time, the sealing ring always fits against the inner wall of the rotating groove to seal the water delivery pipe. This allows for the adjustment of irrigation water volume in each zone according to irrigation needs, achieving precise control of the total amount of irrigation water and avoiding over-irrigation or insufficient water supply. By setting up a transmission rod, when the main gear rotates, the auxiliary gear meshes with the main gear, causing the transmission rod to rotate synchronously, which in turn drives the rotating ball to rotate. This achieves power transmission between the main gear and the rotating ball, allowing operators to control the water flow area inside the water supply pipe synchronously simply by changing the auxiliary gear with a different gear ratio, improving the efficiency of irrigation flow regulation. It also facilitates quick adjustment of the water supply according to different irrigation needs. By setting up a support frame, the transmission rod can be supported and guided, keeping the transmission rod rotating stably. At the same time, the limit frame and the limit groove are movably fitted together to position the auxiliary gear. Then, the auxiliary gear is locked and fixed by bolts and threaded grooves, preventing the auxiliary gear from loosening or shifting during long-term use. This ensures that the main gear and auxiliary gear always maintain stable meshing, improving the transmission reliability and adjustment accuracy of the water control mechanism.

[0017] refer to Figure 1 - Figure 8 A pressure regulating device for a farmland irrigation network includes: a delivery pipe 1, a plurality of delivery holes 2 opened on the outer wall of the delivery pipe 1, a plurality of water supply pipes 3 arranged on the outer wall of the delivery pipe 1, a water spray pipe 4 arranged at one end of the water supply pipe 3, a plurality of water spray holes 5 opened on the outer wall of the water spray pipe 4, a nozzle 6 fixedly connected inside the water spray hole 5, a pressure reducing valve 7 fixedly connected to one end of the water spray pipe 4, the pressure reducing valve 7 being fixedly sleeved together with the water supply pipe 3, a connecting box 8 arranged at one end of the water supply pipe 3, a main gear 9 arranged on the top surface of the connecting box 8, a connecting component arranged inside the connecting box 8 for connecting the water supply pipe 3 and the delivery pipe 1, and a water control component arranged inside the water supply pipe 3 for controlling the water volume; By setting up a delivery pipe 1, irrigation water is first delivered into the delivery pipe 1, and then sent into the water supply pipe 3 through the connecting component. The water flow area inside each water supply pipe 3 is adjusted by the water control component to adjust the irrigation water volume of different zones. Subsequently, the irrigation water is sprayed onto the farmland through the sprinkler pipe 4 and the sprinkler head 6. At the same time, the pressure reducing valve 7 can reduce the water pressure entering the sprinkler pipe 4, so that the sprinkler head 6 can maintain a stable spraying state. In this way, the total amount of irrigation water can be flexibly adjusted according to different farmland areas, soil moisture and crop growth stages, so as to avoid excessive irrigation water causing water waste or insufficient irrigation affecting crop growth. At the same time, the pressure reducing valve 7 can control the water pressure inside the sprinkler pipe 4 according to the local irrigation volume, thereby improving irrigation uniformity and irrigation efficiency.

[0018] As a further embodiment of the present invention, the connecting component includes a connecting hole 10, which is formed on the outer wall of the connecting box 8.

The fixing pipe 13 is fixedly sleeved together with the water supply pipe 3. A positioning component is provided on the top surface of the connecting box 8 for positioning the main gear 9. By setting up the connecting pipe 11, when the irrigation water inside the conveying pipe 1 flows through the conveying hole 2, the irrigation water can enter the connecting box 8 through the connecting pipe 11, and then flow into the water supply pipe 3 through the fixed pipe 13, realizing the connection between the conveying pipe 1 and the water supply pipe 3. At the same time, the positioning component can position the main gear 9, so that the subsequent water control mechanism can maintain stable transmission, thereby ensuring that each water supply pipe 3 can supply water stably and improving the reliability of water supply in each irrigation zone.

[0019] As a further embodiment of the present invention, the positioning component includes a rotating hole 14, which is opened on the top surface of the connecting box 8. A rotating rod 15 is rotatably installed inside the rotating hole 14. A positioning groove 16 is opened on the top surface of the rotating rod 15. A positioning block 17 is fixedly connected to the bottom surface of the main gear 9. The positioning block 17 and the positioning groove 16 are movably fitted together. By setting the rotating rod 15, when it is necessary to adjust the water volume inside the water supply pipe 3, the rotating rod 15 can drive the main gear 9 to rotate synchronously. At the same time, the positioning block 17 and the positioning groove 16 are movably fitted together to position the main gear 9, ensuring that the main gear 9 always maintains a stable installation state. This prevents the main gear 9 from axially moving during the adjustment process, improves transmission stability, and makes the irrigation water volume adjustment more precise.

[0020] As a further embodiment of the present invention, a connecting rod 18 is fixedly connected to the bottom surface of the rotating rod 15, and a water turbine blade 19 is rotatably installed inside the fixed tube 13, with the top end of the water turbine blade 19 fixedly connected to the bottom surface of the connecting rod 18. By setting up the water turbine blade 19, when irrigation water flows through the fixed pipe 13, the water flow drives the water turbine blade 19 to rotate, causing the connecting rod 18 to synchronously drive the rotating rod 15 to rotate, thereby enabling the main gear 9 to rotate synchronously according to the water flow state. In this way, the main gear 9 is automatically driven to rotate using the power of the water flow, which facilitates the subsequent change of the flow rate inside the water delivery pipe 3 according to the water supply state, reduces frequent manual adjustments, and improves the automation level of irrigation water volume regulation.

[0021] As a further embodiment of the present invention, the water control component includes a rotating groove 20, which is opened inside the water supply pipe 3.

A water supply hole 35 is opened on the outer wall of the rotating ball 21. A control component is provided on the outer wall of the water supply pipe 3 for controlling the rotation of the rotating ball 21. By setting a rotating ball 21, when the rotating ball 21 is rotating, the water delivery hole 35 is opened on the outer wall of the rotating ball 21, so that the water delivery hole 35 can form different communication areas with the inside of the water delivery pipe 3, thereby adjusting the water flow rate inside the water delivery pipe 3. At the same time, the sealing ring 22 always fits against the inner wall of the rotating groove 20 to seal the water delivery pipe 3. In this way, the irrigation water volume of each zone can be adjusted according to the irrigation needs, so as to achieve precise control of the total amount of irrigation water and avoid over-irrigation or insufficient water supply.

[0022] As a further embodiment of the present invention, the control component includes a control hole 23, which is opened on the outer wall of the water supply pipe 3. A transmission rod 24 is rotatably installed inside the control hole 23. A secondary gear 25 is provided on the top surface of the transmission rod 24. The main gear 9 meshes with the secondary gear 25. By setting up a transmission rod 24, when the main gear 9 rotates, the auxiliary gear 25 meshes with the main gear 9, causing the transmission rod 24 to rotate synchronously, which in turn drives the rotating ball 21 to rotate. This achieves power transmission between the main gear 9 and the rotating ball 21, allowing the operator to control the water flow area inside the water supply pipe 3 synchronously simply by changing the auxiliary gear 25 with different gear ratios, thereby improving the efficiency of irrigation flow regulation and facilitating quick adjustment of water supply according to different irrigation needs.

[0023] As a further embodiment of the present invention, a limiting frame 26 is provided on the bottom surface of the auxiliary gear 25, a limiting groove 27 is provided on the top surface of the transmission rod 24, the limiting frame 26 and the limiting groove 27 are movably fitted together, a threaded groove 28 is provided on the top surface of the transmission rod 24, a bolt 29 is provided inside the auxiliary gear 25, the bolt 29 is threadedly connected to the threaded groove 28, a support frame 30 is fixedly connected to the outer wall of the connecting box 8, and the transmission rod 24 and the support frame 30 are movably fitted together. By setting up the support frame 30, the support frame 30 can support and guide the transmission rod 24, so that the transmission rod 24 can rotate stably. At the same time, the limiting frame 26 and the limiting groove 27 are movably sleeved together to position the auxiliary gear 25. Then, the auxiliary gear 25 is locked and fixed by bolt 29 and threaded groove 28. This prevents the auxiliary gear 25 from loosening or shifting during long-term use, ensuring that the main gear 9 and the auxiliary gear 25 always maintain stable meshing, and improving the transmission reliability and adjustment accuracy of the water control mechanism.

[0024] As a further embodiment of the present invention, a rotating groove 31 is provided on the bottom surface inside the positioning groove 16, and a rotating plate 32 is rotatably installed inside the rotating groove 31. A placement groove 33 is provided on the bottom surface of the positioning block 17, and a tension spring 34 is fixedly connected to the top surface inside the placement groove 33.
