Description

Technical Field

[0001] The present invention relates to the technical field of water diversion gates for irrigation channels, and in particular to a water diversion gate device on an irrigation channel with a precise diversion function. Background Art

[0002] A sluice gate built at the fork of an irrigation channel to distribute water. It distributes water from the upper channel to the lower channel in a certain proportion and can also be used for water metering. There are two types: open and closed. The former is open-air and simple in structure; the latter is a culvert covered with earth.

[0003] For example, the Chinese patent publication number CN222161158U discloses a water diversion gate device for an irrigation canal, comprising: a fixed frame, a first set of blocks fixedly connected to the outer wall of the front side of the left end of the fixed frame, a rotating shaft body provided at the upper end of the first set of blocks, a second rotating block provided at the right end of the rotating shaft body, a sealing block provided at the front end of the fixed frame, and a clamping block fixedly connected to the outer wall of the sealing block. The utility model can stably move the sealing block toward the right end of the fixed frame through a first sliding mechanism. The two groups of support points in the device make the sealing block in the device more stable when deployed, effectively preventing the gate from being damaged by the impact of large water, and the second sliding mechanism can enable the baffle to move with the second slider, so that floating objects attached to the fixed frame are blocked and salvaged by the baffle, effectively preventing the floating objects from flowing into the next water area and becoming difficult to collect and clean.

[0004] At present, a water diversion gate device for irrigation channels still has some shortcomings. For example, the baffle of the device is a single gate, which achieves rough flow regulation through incomplete closure, and cannot accurately control the precise opening of the gate. It cannot meet the needs of high-precision irrigation scenarios such as drip irrigation and sprinkler irrigation in modern agriculture, especially in plots with mixed planting of multiple crops and large differences in water requirements at different growth stages. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a water diversion gate device with precise diversion function on an irrigation canal, which solves the problems mentioned in the background art.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A water diversion gate device with a precise diversion function on an irrigation canal comprises: an irrigation canal, a diversion block fixedly mounted on the top surface of the irrigation canal, a rotating shaft rotatably mounted on one side of the diversion block, a first water baffle fixedly mounted on the outer circular wall surface of the rotating shaft, and a second water baffle provided on the outer circular wall surface of the rotating shaft; and a diversion regulating assembly, the diversion regulating assembly being arranged on the outer circular wall surface of the rotating shaft and being used to regulate the opening and closing of the first water baffle and the second water baffle.

[0008] By adopting the above technical solution, by setting the first water baffle, the diversion block plays an initial guiding role in water diversion. The guide channel formed by the double water baffles can guide the water flow to divert smoothly, reduce the generation of turbulence and eddy currents, and at the same time improve the fineness of the diversion.

[0009] Preferably, the diversion regulating assembly includes: an inner shaft, an inner shaft is rotatably installed inside the rotating shaft, a connecting block is fixedly installed on the outer circular wall of the inner shaft, the connecting block is fixedly connected to the second water baffle, a first gear ring is fixedly installed on the outer circular wall of the rotating shaft, a second gear ring is fixedly sleeved on the outer circular wall of the inner shaft, a mounting bracket is fixedly installed on the top surface of the diversion block, a first drive motor is fixedly installed on the bottom surface of the mounting bracket, a first gear is fixedly connected to the shaft of the first drive motor, the first gear is meshed with the first gear ring, a second drive motor is fixedly installed on the top surface of the mounting bracket, a connecting hole is opened on the top surface of the mounting bracket, a second gear is fixedly connected to the shaft of the second drive motor, the second gear is meshed with the second gear ring.

[0010] By adopting the above technical solution, by setting an inner shaft, precise control of the double water baffles is achieved through the independent rotation of the inner shaft and the rotating shaft. The first drive motor and the second drive motor independently drive the first gear and the second gear to rotate, thereby driving the first gear ring and the second gear ring to rotate respectively, driving the inner shaft and the rotating shaft to rotate, and the rotation angle of the first water baffle and the second water baffle can be adjusted independently. The angle combination of the two water baffles can flexibly change the distribution ratio of water flow between the main channel and the branch channel, and between the branch channel and the branch channel, to achieve precise diversion in multiple directions and multiple flow rates, and meet the needs of high-precision irrigation scenarios such as drip irrigation and sprinkler irrigation in modern agriculture.

[0011] Preferably, a guide frame is fixedly installed on the top surface of the irrigation channel, a guide opening is opened on the top surface of the guide frame, and a guide rod is fixedly installed on the top surfaces of the first water baffle and the second water baffle, and the guide rod is slidably mounted together with the guide opening.

[0012] By adopting the above technical solution, a guide rod is set up, and the guide opening of the guide frame is arc-shaped, which matches the rotation trajectory of the first water baffle and the second water baffle. When the first water baffle rotates with the rotating shaft, the guide rod on its top slides along the corresponding trajectory of the guide opening, ensuring that the water baffle rotates around the axis of the rotating shaft, avoiding angular deviation caused by mechanical clearance or water flow impact.

[0013] Preferably, a limiting groove is provided on the inner bottom surface of the irrigation channel, and sliding frames are fixedly installed on the bottom surfaces of the first water baffle and the second water baffle, and rollers are rotatably installed inside the sliding frames.

[0014] By adopting the above technical solution, by setting rollers, the limit groove trajectory matches the rotation trajectory of the first water baffle and the second water baffle. When the water baffle rotates under the drive of the first drive motor or the second drive motor, the roller at the bottom rolls along the limit groove trajectory, and forms "upper and lower double constraints" with the sliding of the top guide rod along the guide mouth, jointly limiting the movement path of the water baffle. The roller in the sliding frame converts the sliding friction of the water baffle during rotation into rolling friction, greatly reducing the movement resistance and reducing the direct wear between the bottom of the water baffle and the bottom surface of the channel body.

[0015] Preferably, a first articulated frame is fixedly installed on one side of the first and second water baffles, a second articulated frame is fixedly installed on both sides of the diversion block, a hydraulic rod is hingedly installed inside the second articulated frame, and the axis of the hydraulic rod is hingedly installed together with the first articulated frame.

[0016] By adopting the above technical solution and setting a hydraulic rod, when the first drive motor drives the first water baffle to rotate, the hydraulic rod on the corresponding side will extend and retract synchronously with the angle change of the water baffle: when the water baffle rotates to one side, the hydraulic rod will extend to adapt to the angle change; when it rotates to the other side, the hydraulic rod will shorten, and the displacement of the water baffle will be compensated by the rotation of the hinge point. The hydraulic rod is driven by the hydraulic power auxiliary motor and can provide greater thrust or pull, ensuring that the angle of the water baffle can still be accurately adjusted under high load.

[0017] Preferably, a positioning hole is opened on the inner bottom surface of the irrigation channel, a positioning frame is fixedly installed on one side of the first water baffle and the second water baffle, a third drive motor is fixedly installed on the top surface of the positioning frame, the shaft of the third drive motor is fixedly connected to a threaded rod, and the external thread of the threaded rod is connected to a positioning sleeve.

[0018] By adopting the above technical solution and setting a positioning sleeve, when the first water baffle or the second water baffle closes the irrigation channel to store water, the output shaft of the third drive motor drives the threaded rod to rotate, and the rotation of the threaded rod is converted into a vertical lifting movement of the positioning sleeve, so that the positioning sleeve is inserted into the positioning hole to form a mechanical lock. When a strong water flow impacts, the water baffle is prevented from flipping or displacement due to excessive force, thereby ensuring the safe operation of the irrigation system.

[0019] Preferably, a sealing block is fixedly adhered to one side of the first water baffle and the second water baffle.

[0020] By adopting the above technical solution and setting up a sealing block, after the first water baffle and the second water baffle are rotated and adjusted, there may be tiny gaps between their edges and the inner wall of the irrigation channel or the diversion block. The sealing block fills these gaps through its own deformation to form a tightly fitting sealing surface, thereby reducing leakage.

[0021] Preferably, an interception net is provided inside the irrigation channel.

[0022] By adopting the above technical solution and setting up an interception net, the water flow in the irrigation channel is often mixed with large impurities such as branches, stones, and weeds. If it directly rushes towards the first water baffle, the second water baffle or enters the transmission area such as the rotating shaft and the inner shaft, it may cause the water baffle to get stuck, the gear meshing to be abnormal, or even the motor to be overloaded and damaged.

[0023] In summary, the present invention mainly has the following beneficial effects:

[0024] By setting an inner shaft, precise control of the double water baffles is achieved through the independent rotation of the inner shaft and the rotating shaft. The first drive motor and the second drive motor independently drive the first gear and the second gear to rotate, thereby driving the first gear ring and the second gear ring to rotate respectively, driving the inner shaft and the rotating shaft to rotate, and the rotation angles of the first water baffle and the second water baffle can be adjusted independently. The angle combination of the two water baffles can flexibly change the distribution ratio of water flow between the main channel and branch channels, and between branch channels, to achieve precise diversion in multiple directions and multiple flow rates, meeting the needs of high-precision irrigation scenarios such as drip irrigation and sprinkler irrigation in modern agriculture.

[0025] By setting a guide rod, the guide opening of the guide frame is arc-shaped, which matches the rotation trajectory of the first water baffle and the second water baffle. When the first water baffle rotates with the rotating shaft, the guide rod on its top slides along the corresponding trajectory of the guide opening to ensure that the water baffle rotates around the axis of the rotating shaft to avoid angular deviation caused by mechanical clearance or water flow impact. By setting rollers, the limit groove trajectory matches the rotation trajectory of the first water baffle and the second water baffle. When the water baffle rotates under the drive of the first drive motor or the second drive motor, the bottom roller rolls along the limit groove trajectory, forming "up and down double constraints" with the sliding of the top guide rod along the guide opening, jointly limiting the movement path of the water baffle. The rollers in the sliding frame convert the sliding friction of the water baffle during rotation into rolling friction, greatly reducing the movement resistance and reducing the direct wear between the bottom of the water baffle and the bottom surface of the channel body.

[0026] By setting a hydraulic rod, when the first drive motor drives the first water baffle to rotate, the hydraulic rod on the corresponding side extends and retracts synchronously with the change of the angle of the water baffle: when the water baffle rotates to one side, the hydraulic rod extends to adapt to the angle change; when it rotates to the other side, the hydraulic rod shortens, and the displacement of the water baffle is compensated by the rotation of the hinge point. The hydraulic rod is driven by the hydraulic power auxiliary motor, which can provide greater thrust or pull, ensuring that the water baffle can still accurately adjust the angle under high load, ensuring that the water baffle can still accurately adjust the angle under high load. By setting a positioning sleeve, when the first water baffle or the second water baffle closes the irrigation channel to store water, the output shaft of the third drive motor drives the threaded rod to rotate, and the rotation of the threaded rod will be converted into a vertical lifting motion of the positioning sleeve, so that the positioning sleeve is inserted into the positioning hole to form a mechanical lock, which can prevent the water baffle from flipping or displacement due to excessive force when impacted by strong water flow, thereby ensuring the safe operation of the irrigation system.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] By setting the first water baffle 4, the diversion block 2 plays an initial guiding role in water diversion. The guide channel formed by the double water baffles can guide the water to divert smoothly, reduce the generation of turbulence and eddy currents, and improve the fineness of the diversion.

[0037] As a further solution of the present invention, the shunt regulating assembly includes: an inner shaft 6, an inner shaft 6 is rotatably mounted on the interior of the rotating shaft 3, a connecting block 15 is fixedly mounted on the outer circular wall surface of the inner shaft 6, the connecting block 15 is fixedly connected to the second water baffle 5, a first gear ring 7 is fixedly mounted on the outer circular wall surface of the rotating shaft 3, a second gear ring 8 is fixedly sleeved on the outer circular wall surface of the inner shaft 6, a mounting bracket 9 is fixedly mounted on the top surface of the shunt block 2, a first drive motor 10 is fixedly mounted on the bottom surface of the mounting bracket 9, a first gear 11 is fixedly connected to the shaft of the first drive motor 10, the first gear 11 is meshed with the first gear ring 7, a second drive motor 12 is fixedly mounted on the top surface of the mounting bracket 9, a connecting hole 13 is provided on the top surface of the mounting bracket 9, a second drive motor 12 is fixedly connected to the shaft of the second drive motor 12, and the second gear 14 is meshed with the second gear ring 8;

[0038] By setting the inner shaft 6, precise control of the double water baffles is achieved through the independent rotation of the inner shaft 6 and the rotating shaft 3. The first drive motor 10 and the second drive motor 12 independently drive the first gear 11 and the second gear 14 to rotate, thereby driving the first gear ring 7 and the second gear ring 8 to rotate respectively, driving the inner shaft 6 and the rotating shaft 3 to rotate, and the rotation angles of the first water baffle 4 and the second water baffle 5 can be adjusted independently. The angle combination of the two water baffles can flexibly change the distribution ratio of water flow between the main channel and the branch channel, and between the branch channel and the branch channel, to achieve precise diversion in multiple directions and multiple flow rates, meeting the needs of high-precision irrigation scenarios such as drip irrigation and sprinkler irrigation in modern agriculture.

[0039] As a further embodiment of the present invention, a guide frame 16 is fixedly mounted on the top surface of the irrigation channel 1, a guide opening 17 is opened on the top surface of the guide frame 16, and a guide rod 18 is fixedly mounted on the top surfaces of the first water baffle 4 and the second water baffle 5, and the guide rod 18 is slidably mounted on the guide opening 17;

[0040] By setting a guide rod 18, the guide opening 17 of the guide frame 16 is arc-shaped, which matches the rotation trajectory of the first water baffle 4 and the second water baffle 5. When the first water baffle 4 rotates with the rotating shaft 3, the guide rod 18 on its top slides along the corresponding trajectory of the guide opening 17 to ensure that the water baffle rotates around the axis of the rotating shaft 3, avoiding angular deviation caused by mechanical clearance or water flow impact.

[0041] As a further solution of the present invention, a limiting groove 19 is provided on the inner bottom surface of the irrigation channel 1, and a sliding frame 20 is fixedly installed on the bottom surface of the first water baffle 4 and the second water baffle 5, and a roller 21 is rotatably installed inside the sliding frame 20;

[0042] By setting the roller 21, the trajectory of the limit groove 19 matches the rotation trajectory of the first water baffle 4 and the second water baffle 5. When the water baffle rotates under the drive of the first drive motor 10 or the second drive motor 12, the roller 21 at the bottom rolls along the trajectory of the limit groove 19, and forms a "double constraint up and down" with the sliding of the top guide rod 18 along the guide mouth 17, jointly limiting the movement path of the water baffle. The roller 21 in the sliding frame 20 converts the sliding friction during the rotation of the water baffle into rolling friction, greatly reducing the movement resistance and reducing the direct wear between the bottom of the water baffle and the bottom surface of the channel body.

[0043] As a further solution of the present invention, a first articulated frame 22 is fixedly installed on one side of the first water baffle 4 and the second water baffle 5, and a second articulated frame 24 is fixedly installed on both sides of the diverter block 2. A hydraulic rod 23 is hingedly installed inside the second articulated frame 24, and the axis of the hydraulic rod 23 is hingedly installed with the first articulated frame 22;

[0044] By setting a hydraulic rod 23, when the first drive motor 10 drives the first water baffle 4 to rotate, the hydraulic rod 23 on the corresponding side extends and retracts synchronously with the angle change of the water baffle: when the water baffle rotates to one side, the hydraulic rod 23 extends to adapt to the angle change; when it rotates to the other side, the hydraulic rod 23 shortens, and the displacement of the water baffle is compensated by the rotation of the hinge point. The hydraulic rod 23 is driven by a hydraulic power auxiliary motor and can provide greater thrust or pulling force, ensuring that the water baffle can still accurately adjust the angle under high load, ensuring that the water baffle can still accurately adjust the angle under high load.

[0045] As a further embodiment of the present invention, a positioning hole 25 is formed on the inner bottom surface of the irrigation channel 1, a positioning frame 26 is fixedly mounted on one side of the first water baffle 4 and the second water baffle 5, a third drive motor 27 is fixedly mounted on the top surface of the positioning frame 26, a threaded rod 28 is fixedly connected to the shaft of the third drive motor 27, and a positioning sleeve 29 is threadedly connected to the outer surface of the threaded rod 28;

[0046] By setting the positioning sleeve 29, when the first water baffle 4 or the second water baffle 5 closes the irrigation channel 1 to store water, the output shaft of the third drive motor 27 drives the threaded rod 28 to rotate, and the rotation of the threaded rod 28 will be converted into a vertical lifting movement of the positioning sleeve 29, so that the positioning sleeve 29 is inserted into the positioning hole 25 to form a mechanical lock. When a strong water flow impacts, the water baffle is prevented from flipping or displacement due to excessive force, thereby ensuring the safe operation of the irrigation system.

[0047] As a further solution of the present invention, a sealing block 30 is fixedly adhered to one side of the first water retaining plate 4 and the second water retaining plate 5;

[0048] By setting the sealing block 30, after the first water baffle 4 and the second water baffle 5 are rotated and adjusted, there may be tiny gaps between their edges and the inner wall of the irrigation channel 1 or the diversion block 2. The sealing block 30 fills these gaps by its own deformation, forming a tightly fitting sealing surface and reducing leakage.

[0049] As a further solution of the present invention, an interception net 31 is provided inside the irrigation channel 1;

[0050] By setting up the interception net 31, the water flow in the irrigation channel 1 is often mixed with large impurities such as branches, stones, and weeds. If it directly rushes towards the first water baffle 4, the second water baffle 5 or enters the transmission area such as the rotating shaft 3 and the inner shaft 6, it may cause the water baffle to get stuck, the gear meshing to be abnormal, or even the motor to be overloaded and damaged.

[0051] Working principle: Please refer to Figures 1-6As shown, after entering the irrigation channel 1, the water first passes through the internal interception net 31. The interception net 31 filters out large impurities such as branches, stones, and weeds, as well as some impurity clumps containing mud and sand, from the water flow, preventing these impurities from damaging subsequent components or affecting their normal operation. The water then reaches the diversion block 2, which serves as the initial guide for water diversion. A first water baffle 4 is fixed to a rotating shaft 3 rotatably mounted on one side of the diversion block, and a second water baffle 5 is also provided on the outer wall of the rotating shaft 3. The diversion channel formed by the double water baffles guides the water flow for smooth diversion, reducing turbulence and eddies, while improving the diversion precision. When the diversion needs to be adjusted, the diversion adjustment component starts working, and the first drive motor 10 on the bottom of the mounting frame 9 starts, driving the first gear 11 to rotate. Since the first gear 11 is engaged with the first gear ring 7 on the outer cylindrical wall of the rotating shaft 3, the rotating shaft 3 and the first water baffle 4 are driven to rotate around their own axis; the second drive motor 12 on the top of the mounting frame 9 is started, and its shaft passes through the connecting hole 13 to drive the second gear 14 to rotate. The second gear 14 is engaged with the second gear ring 8 on the outer cylindrical wall of the inner shaft 6, thereby driving the inner shaft 6 to rotate. The inner shaft 6 drives the second water baffle 5 to rotate through the connecting block 15, thereby realizing independent adjustment of the rotation angles of the first water baffle 4 and the second water baffle 5, so as to flexibly change the distribution ratio of water flow between the main channel and the branch channel, and between the branch channel and the branch channel. During the rotation of the water baffle, the guide frame 16 fixedly installed on the top surface of the irrigation channel 1 plays a role. The guide opening 17 on the guide frame 16 is arc-shaped and matches the rotation trajectory of the water baffle. The guide rod 18 on the top surface of the first water baffle 4 and the second water baffle 5 slides along the guide opening 17 to provide top constraint for the rotation of the water baffle; at the same time, the limit groove 19 on the bottom surface of the irrigation channel 1 cooperates with the roller 21 in the sliding frame 20 on the bottom surface of the water baffle. The roller 21 rolls along the limit groove 19, forming a "double constraint up and down" with the top guide, jointly limiting the movement path of the water baffle, and the roller 21 converts sliding friction into rolling friction, reducing movement resistance and wear. In addition, the first articulated frame 22 on one side of the first water baffle 4 and the second water baffle 5 is hinged to the hydraulic rod 23 on the second articulated frame 24 on both sides of the diversion block 2. When the water baffle rotates, the hydraulic rod 23 extends and retracts synchronously, assisting the motor drive to provide greater thrust or pulling force, ensuring that the water baffle can still be accurately adjusted under high load. After adjusting to the target angle, the hydraulic rod 23 is locked to maintain the angle. If the angle of the water baffle needs to be fixed, the third drive motor 27 on the positioning frame 26 is started, driving the threaded rod 28 to rotate, so that the positioning sleeve 29 connected to the external thread of the threaded rod 28 is vertically raised and lowered, and inserted into or disengaged from the positioning hole 25 on the bottom surface of the irrigation channel 1, forming a mechanical lock to prevent the water baffle from flipping or displacement when a strong water flow impacts.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
