[0029] 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.

[0030] Please see Figure 1 This embodiment of a high-standard farmland active irrigation device includes a fixed plate 1, with fixed blocks 2 fixed at both ends of the fixed plate 1. A threaded rod 3 is threadedly connected to the upper surface of the fixed block 2, with one end penetrating and extending to its lower side. The two threaded rods 3 improve the stability between the fixed plate 1 and the ground. A controller 4 is provided at the top of the left end of the fixed plate 1. A height adjustment mechanism 5 for adjusting the irrigation height is provided in the middle of the inner cavity of the fixed plate 1. An angle adjustment mechanism 6 for adjusting the irrigation angle is provided on the upper side of the fixed plate 1.

[0031] In this embodiment, a water pump is provided on the right side of the fixing plate 1. The input end of the water pump is connected to the water source through a water pipe, and the output end of the water pump is fixed to the right side of the hollow plate 603 through a water pipe and connected to its inner cavity.

[0032] It should be noted that the device includes monitoring nodes, which form a wireless sensor actuator network according to a star network topology. The LoRa module circuit is responsible for wireless communication, enabling real-time data acquisition and transmission. The aggregation node obtains sensor data from the monitoring nodes one by one through a query method and uploads the data to the database of the cloud server, recording irrigation duration and data. The average current of the monitoring node and the aggregation node during one day of operation is as low as approximately 1.21mA and 30.10mA, respectively, ensuring the long-term stable operation of the system.

[0033] Please see Figures 2 to 3 To enable a wider irrigation range, the angle adjustment mechanism 6 in this embodiment includes a bearing plate 601, two support seats 602, a hollow plate 603, a first motor 604, a rotating rod 605, several first gears 606, several connecting frames 607, several shafts 608, several solenoid valves 609, several nozzles 610, and several second gears 611. The bearing plate 601 is located on the upper side of the fixed plate 1. The two support seats 602 are fixed to the left and right ends of the upper surface of the bearing plate 601. The hollow plate 603 is fixed between the opposite sides of the two support seats 602. The first motor 604 is fixed to the bottom left side of the right support seat 602. The right side of the rotating rod 605 is connected to the output of the first motor 604. The shaft is fixed, and the first gear 606 is fixed on the outer surface of the rotating rod 605. The controller 4 starts the first motor 604, and the output shaft of the first motor 604 rotates, which drives the rotating rod 605 to rotate. The rotation of the rotating rod 605 causes the first gear 606 fixed on its outer surface to rotate. The connecting frame 607 is fixed on the front and rear sides of the hollow plate 603. The solenoid valve 609 is located in the inner cavity of the connecting frame 607. The left and right sides of the solenoid valve 609 are fixed to the shaft 608. The side of the shaft 608 away from the solenoid valve 609 is rotatably connected to the inner wall of the connecting frame 607 through a bearing. The nozzle 610 is connected to the solenoid valve 609. The second gear 611 is fixed on the outer surface of the left end shaft 608 inside the connecting frame 607.

[0034] The left side of the rotating rod 605 is rotatably connected to the right side of the left end support 602 via a bearing. Several first gears 606 are fixed on the outer surface of the rotating rod 605. The connecting frame 607 has an inverted U-shaped cross-section. The second gear 611 meshes with the first gear 606. The rotation of the first gear 606 causes the second gear 611 to rotate. The rotation of the second gear 611 drives the rotation of the left end shaft 608. The rotation of the left end shaft 608 drives the solenoid valve 609 to rotate, thereby changing the angle of the nozzle 610. The input end of valve 609 is connected to the inner cavity of hollow plate 603 through a flexible hose. Several connecting brackets 607 are evenly distributed on the outer surface of hollow plate 603. Controller 4 can open the corresponding solenoid valve 609, allowing water in the inner cavity of hollow plate 603 to enter the inner cavity of nozzle 610 through the flexible hose, thereby irrigating farmland. Adjusting the angle of solenoid valve 609 changes the angle of nozzle 610, thus expanding the irrigation range. The solenoid valve 609 can also be used for targeted irrigation, improving the irrigation effect of farmland.

[0035] In this embodiment, telescopic rods are fixed at both ends of the fixed plate 1 and the bearing plate 601 on opposite sides, and the two telescopic rods are evenly distributed between the fixed plate 1 and the bearing plate 601 on opposite sides.

[0036] It should be noted that the movement of the bearing plate 601 causes the two telescopic rods to extend, which can limit the movement of the bearing plate 601. Sprinklers 610 are provided on both the front and rear sides of the hollow plate 603, which improves the irrigation efficiency.

[0037] Please see Figure 4 To adjust the irrigation height, the height adjustment mechanism 5 in this embodiment includes a second motor 501, a screw 502, a screw sleeve 503, and two linkage rods 504. A through groove 505 is provided in the middle of the inner cavity of the fixing plate 1. The second motor 501 is fixed to the inner bottom wall of the through groove 505. The output shaft of the second motor 501 is fixed to the screw 502. The screw sleeve 503 is threadedly connected to the screw 502. The controller 4 starts the second motor 501. The output shaft of the second motor 501 rotates, causing the screw 502 to rotate. The rotation of the screw 502 causes the screw sleeve 503, which is threadedly connected to it, to move upward. The two linkage rods 504 are fixed on the left and right sides of the screw sleeve 503. The top of the linkage rod 504 passes through the through groove 505 and extends to the upper side of the fixing plate 1 and is fixed to the support plate 601. The movement of the screw sleeve 503 causes the two linkage rods 504 to move upward. The movement of the linkage rods 504 pushes the support plate 601 to move upward. The upward movement of the support plate 601 can drive the nozzle 610 to rise.

[0038] In this embodiment, limit grooves are provided on the opposite sides of the left and right side walls of the inner cavity of the through groove 505, and limit blocks are fixed at the bottom of the opposite sides of the two linkage rods 504. The limit blocks move up and down linearly within the inner cavity of the limit grooves.

[0039] It is understandable that the height of the bearing plate 601 can be adjusted by the cooperation between the second motor 501, the screw 502, the screw sleeve 503 and the linkage rod 504, thereby changing the height of the nozzle 610. In conjunction with the angle adjustment mechanism 6, it can irrigate farmland.

[0040] The working principle of the above embodiments is as follows:

[0041] (1) The stability between the fixed plate 1 and the ground can be improved by setting two threaded rods 3. When irrigating farmland, since there is a humidity sensor in the farmland, the humidity sensor can send a signal to the controller 4. After receiving the signal, the controller 4 can control the height and angle of the nozzle 610. When adjusting the height of the nozzle 610, the controller 4 first starts the second motor 501. The output shaft of the second motor 501 rotates and drives the screw 502 to rotate. The rotation of the screw 502 causes the threaded sleeve 503 connected to it to move upward. Due to the setting of the limit block and the limit groove, the threaded sleeve 503 can only move in a straight line. The movement of the threaded sleeve 503 drives the two linkage rods 504 to move upward. The movement of the linkage rods 504 pushes the bearing plate 601 to move upward. The upward movement of the bearing plate 601 can drive the nozzle 610 to rise. The movement of the bearing plate 601 drives the two telescopic rods to extend, which can limit the movement of the bearing plate 601.

[0042] (2) When adjusting the angle of the nozzle 610, the controller 4 starts the first motor 604. The output shaft of the first motor 604 rotates, which drives the rotating rod 605 to rotate. The rotation of the rotating rod 605 causes the first gear 606 fixed on its outer surface to rotate. The rotation of the first gear 606 causes the second gear 611 to rotate. The rotation of the second gear 611 drives the left end shaft 608 to rotate. The rotation of the left end shaft 608 drives the solenoid valve 609 to rotate, thereby changing the angle of the nozzle 610. Then the controller 4 can open the corresponding solenoid valve 609, so that the water in the inner cavity of the hollow plate 603 can enter the inner cavity of the nozzle 610 through the hose, thereby irrigating the farmland.
