Description

Technical Field

[0001] This utility model relates to the field of water conservancy and irrigation technology, specifically to a water conservancy irrigation device for water conservancy construction. Background Technology

[0002] Water conservancy projects involve the control and utilization of surface water and groundwater. Irrigation is a convenient and environmentally friendly way to utilize surface water and groundwater, which can both protect water resources and promote agricultural production. Sprinkler irrigation is the most common irrigation method in Chinese agricultural production. Water is delivered to farmland through pipelines and then sprayed out through sprinklers to irrigate the farmland.

[0003] Existing irrigation equipment uses rotating nozzles for large-area irrigation during sprinkler irrigation. The angle of the nozzle is fixed during the rotation process, and it is not possible to simultaneously adjust the small vertical angle of the nozzle while rotating. This results in a fixed directional spraying range, which can easily lead to excessive water volume at close range and insufficient water volume at long range, as well as significant deviations in water volume at different ranges within the irrigation coverage area. Based on this, a new irrigation equipment for water conservancy construction is proposed. Utility Model Content

[0004] This utility model provides a water conservancy irrigation device for water conservancy construction, which solves the problem mentioned in the above technical background that the angle of the nozzle of the existing irrigation equipment is fixed during the rotation of the sprinkler, the directional spraying range is fixed, which easily causes excessive water volume at the near range and insufficient water volume at the far range, and large deviations in water volume at different ranges within the irrigation coverage area.

[0005] A water conservancy irrigation device for water conservancy construction includes a fixed base, a water supply pipe fixedly installed inside the fixed base, a branch pipe fixedly installed at the top of the water supply pipe, support rods fixedly installed on both sides of the top of the fixed base, a bearing seat fixedly installed at the top of the support rods, a support rod rotatably connected to the middle of the top of the bearing seat via a bearing, connecting rods rotatably connected to both sides of the top of the support rods, a nozzle fixedly installed at the end of the connecting rod, a horizontal plate fixedly installed below the support rod, and adjustment mechanisms for moving the nozzle up and down on both sides of the top of the horizontal plate. Two flexible hoses are fixedly connected to the top of the branch pipe, and the flexible hoses are fixedly connected to the nozzles.

[0006] Preferably, the adjusting mechanism includes a rotating rod rotatably connected to the horizontal plate, a cylindrical tube fixedly mounted on the rotating rod, an elliptical groove formed on the surface of the cylindrical tube, a slider slidably connected in the elliptical groove, a movable rod fixedly connected to one side of the slider, and the top of the movable rod slidably connected to the bottom of the connecting rod.

[0007] Preferably, the top two sides of the support seat are fixedly provided with arc-shaped slides, the bottom of the rotating rod extends through into the arc-shaped slide and is fixedly fitted with a gear, and an arc-shaped rack is fixedly provided on one inner wall of the arc-shaped slide, and the gear meshes with the arc-shaped rack.

[0008] Preferably, the center of the arc-shaped rack and the center of the support rod during rotation are on the same vertical axis.

[0009] Preferably, both the rotating rod and the movable rod are configured as electrically telescopic rods.

[0010] Preferably, the bottom of the support base is fixedly provided with a housing, the bottom of the support rod extends through into the housing and is fixedly fitted with a first bevel gear and a second bevel gear, a motor is fixedly provided on one side of the housing, and the output shaft of the motor is fixedly connected with a bevel half gear, the bevel half gear meshing with the first bevel gear and the second bevel gear.

[0012] Preferably, the water pipe is provided with a first connector and a second connector at both ends, and the first connector and the second connector are threaded together.

[0013] The beneficial effects of this utility model are: (1) In this utility model, while the support rod drives the nozzle to rotate horizontally, the horizontal plate below the support rod rotates synchronously. The rotating rod and gear on the horizontal plate move synchronously in the arc-shaped slide. While the gear moves, it continuously meshes with the arc-shaped rack, so that the gear drives the rotating rod and the cylindrical tube to rotate continuously. As the cylindrical tube rotates, the slider slides in the elliptical groove and drives the movable rod to move up and down while sliding, which drives the connecting rod and the nozzle at its end to move up and down, thereby adjusting the angle of the nozzle. This achieves the synchronous and coordinated effect of horizontal rotation and vertical angle adjustment of the nozzle. While rotating horizontally, the vertical angle of the nozzle is dynamically adjusted to correct the water volume imbalance caused by the difference in the parabolic trajectory of water droplets during irrigation, avoid large deviations in water volume at different ranges within the irrigation coverage area, and solve the problem of near flooding and distant drought caused by single-angle rotation.

[0014] (2) In this utility model, the motor drives the bevel half gear to rotate. The bevel half gear meshes with the first bevel gear and the second bevel gear in turn, so that the first bevel gear and the second bevel gear drive the support rod to rotate in opposite directions. The direction of rotation of the support rod and the nozzle can be adjusted without changing the direction of rotation of the motor. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figure 1-4 As shown, a water conservancy construction irrigation device includes a fixed base 1, with a fixing nail fixed at the bottom of the fixed base 1. A water supply pipe 2 is fixed inside the fixed base 1, and a branch pipe 3 is fixed at the top of the water supply pipe 2. Support rods 4 are fixed on both sides of the top of the fixed base 1, and a bearing seat 5 is fixed at the top of the support rods 4. A support rod 6 is rotatably connected to the middle of the top of the bearing seat 5 via a bearing. Connecting rods 7 are rotatably connected to both sides of the top of the support rod 6. A nozzle 8 is fixed at the end of the connecting rod 7. A horizontal plate 9 is fixed below the support rod 6. Adjustment mechanisms for the up and down movement of the nozzle 8 are provided on both sides of the top of the horizontal plate 9. Two flexible hoses 10 are fixedly connected to the top of the branch pipe 3, and the flexible hoses 10 are fixedly connected to the nozzle 8.

[0019] The adjustment mechanism includes a rotating rod 11 rotatably connected to the horizontal plate 9. The rotating rod 11 is rotatably connected to the horizontal plate 9 via a bearing. A cylindrical tube 12 is fixedly mounted on the rotating rod 11. An elliptical groove 13 is formed on the surface of the cylindrical tube 12. A slider 14 is slidably connected in the elliptical groove 13. A movable rod 15 is fixedly connected to one side of the slider 14. The top of the movable rod 15 is slidably connected to the bottom of the connecting rod 7.

[0020] The cylindrical tube 12 is rotated by rotating rod 11, and the slider 14 slides in the elliptical groove 13. While sliding, it drives the movable rod 15 to move up and down, which in turn drives the connecting rod 7 and the nozzle 8 at its end to move up and down, thereby adjusting the angle of the nozzle 8.

[0021] The top two sides of the bearing seat 5 are fixedly provided with arc-shaped slide seats 16. The bottom of the rotating rod 11 extends through into the arc-shaped slide seat 16 and is fixedly fitted with a gear 17. An arc-shaped rack 18 is fixedly provided on one inner wall of the arc-shaped slide seat 16. The gear 17 and the arc-shaped rack 18 are meshed and connected.

[0022] While the support rod 6 drives the nozzle 8 to rotate horizontally, the horizontal plate 9 below the support rod 6 rotates synchronously. The rotating rod 11 and gear 17 on the horizontal plate 9 move synchronously within the arc-shaped slide 16. The gear 17 continuously meshes with the arc-shaped rack 18 during its movement, causing the gear 17 to drive the rotating rod 11 and the cylindrical cylinder 12 to rotate continuously. The rotation of the cylindrical cylinder 12 drives the adjustment of the vertical angle of the nozzle 8, thereby achieving a synchronous and coordinated effect of horizontal rotation and vertical angle adjustment of the nozzle 8. While rotating horizontally, the vertical angle of the nozzle is dynamically adjusted, correcting the water imbalance caused by the difference in the parabolic trajectory of water droplets during irrigation, and solving the problem of near-term flooding and distant drought caused by single-angle rotation.

[0023] The center of the arc-shaped rack 18 is on the same vertical axis as the center of the support rod 6 when it rotates, ensuring that when the rotating rod 11 rotates with the horizontal plate 9, the gear 17 at the bottom of the rotating rod 11 always meshes with the arc-shaped rack 18 inside the arc-shaped slide 16.

[0024] Both the rotating rod 11 and the movable rod 15 are electrically telescopic rods. By extending and retracting the rotating rod 11, the gear 17 moves up and down, controlling the meshing of the gear 17 with the arc-shaped rack 18. This allows for both fixed-angle irrigation and horizontal rotation with angle adjustment, providing greater flexibility. By extending and retracting the movable rod 15, the range of angle adjustment of the nozzle 8 at the end of the connecting rod 7 can be adjusted. For example, extending the movable rod 15 allows the nozzle 8 to swing at an angle of 30°-40°, while shortening the movable rod 15 allows the nozzle 8 to swing at an angle of 25°-35°.

[0025] The bottom of the support base 5 is fixedly provided with a housing 19. The bottom of the support rod 6 extends through into the housing 19 and is fixedly fitted with a first bevel gear 20 and a second bevel gear 21. A motor 22 is fixedly provided on one side of the housing 19. The output shaft of the motor 22 is fixedly connected to a bevel half gear 23. The bevel half gear 23 meshes with the first bevel gear 20 and the second bevel gear 21. When the bevel half gear 23 meshes with the first bevel gear 20, it separates from the second bevel gear 21.

[0026] The motor 22 drives the bevel gear 23 to rotate. The bevel gear 23 meshes with the first bevel gear 20 and the second bevel gear 21 in turn, so that the first bevel gear 20 and the second bevel gear 21 drive the support rod 6 to rotate in opposite directions. This causes the support rod 6 to drive the nozzle 8 to swing continuously, expanding the irrigation range.

[0027] The bottom of the connecting rod 7 has a limiting groove 24, and the top of the movable rod 15 is hinged to a limiting block 25. The limiting block 25 is slidably connected in the limiting groove 24. Both the limiting groove 24 and the limiting block 25 are set as T-shaped structures to improve the stability of the movable rod 15 when it slides at the bottom of the connecting rod 7 to move the connecting rod 7 and the nozzle 8 at its end up and down, and to adjust the spraying angle of the nozzle 8.

[0028] The water supply pipe 2 has a first connector 26 and a second connector 27 at both ends. A control valve is provided on one side of the water supply pipe 2. The first connector 26 and the second connector 27 are threaded together. The second connector 27 is movably connected to one end of the water supply pipe 2. Both ends of the water supply pipe 2 are provided with sealing gaskets. By rotating the second connector 27 and threading it with the first connector 26, multiple water supply pipes 2 can be connected together. Multiple water supply pipes 2 can be laid according to the area to be irrigated. In addition, the equipment also includes a connecting pipe. The two ends of the connecting pipe are also provided with a first connector 26 and a second connector 27. The distance between the water supply pipe 2 and the nozzle 8 is adjusted through the connecting pipe.

[0029] In use, water supply pipes 2 are fixed at appropriate distances according to the required irrigation range. The water supply pipes 2 are connected by connecting pipes. One end of each water supply pipe 2 is connected to a water source via a water pump. The water pump delivers water into the water supply pipes 2 and sprays it out from the nozzles 8. During irrigation, the motor 22 drives the bevel gear 23 to rotate. The bevel gear 23 meshes with the first bevel gear 20 and the second bevel gear 21 in sequence, causing the first bevel gear 20 and the second bevel gear 21 to drive the support rod 6 to rotate in opposite directions. This causes the support rod 6 to continuously swing the nozzles 8, and the horizontal plate 9 below the support rod 6 rotates synchronously. The rotating rod 11 and gear 17 on the horizontal plate 9... The synchronous movement within the arc-shaped slide block 16 causes the gear 17 to continuously mesh with the arc-shaped rack 18, thereby driving the rotating rod 11 and the cylindrical cylinder 12 to rotate continuously. The slider 14 slides within the elliptical groove 13 on the cylindrical cylinder 12, and simultaneously drives the movable rod 15 to move up and down, adjusting the angle of the nozzle 8. This achieves a synchronous and coordinated effect of horizontal rotation and vertical angle adjustment of the nozzle 8, dynamically adjusting the vertical angle of the nozzle while rotating horizontally. This corrects the water volume imbalance caused by the difference in the parabolic trajectory of water droplets during irrigation, avoids large deviations in water volume at different ranges within the irrigation coverage area, and solves the problem of near-flooding and far-drought due to single-angle rotation.

[0030] It should be noted that, for the present invention as fully described, there may be various variations and modifications, and it is not limited to the specific embodiments described above. In summary, the scope of protection of this utility model should include those variations, substitutions, and modifications that are obvious to those skilled in the art, and the appended claims shall prevail.
