[0003] Currently, when water conservancy projects divert water, they typically direct the flow to multiple irrigation canals for farmland. At these points, a gate structure is installed to control the water flow direction. During diversion, debris from the main channel flows into the diverted irrigation canals, causing significant amounts of floating or settling debris, affecting subsequent irrigation. This necessitates the removal of this debris by workers, increasing their workload and labor intensity. Summary of the Invention

[0010] Preferably, a rotating rod is rotatably connected between the first gantry and the second gantry. The rotating rod is provided with a first drum and a movable gear. A rack plate that meshes with the movable gear is provided on the piston rod of one of the hydraulic cylinders. A second pull rope is wound around the first drum. The end of the second pull rope away from the first drum is connected to the receiving seat.

[0011] Preferably, a working pipe is fixedly provided on the outside of the diversion channel, a connecting groove is provided between the working pipe and the diversion channel, a drain pipe is provided at the bottom of the working pipe, a one-way valve is provided on the drain pipe, the end of the drain pipe away from the working pipe is connected to a first slide plate, a cavity is provided on the first slide plate that communicates with the drain pipe, and a plurality of water spray nozzles are provided on the outside of the first slide plate that communicate with the cavity.

[0012] Preferably, a second drum is provided on the rotating rod, and a third pull rope is wound and connected to the second drum.

[0013] Preferably, the diversion channel has a guide surface on its side wall for debris to fall, and a debris trough is provided on one side of the guide surface.

[0014] This invention also discloses a diversion method for a water diversion device in a water conservancy project, comprising the following steps: S1: When diverting water for irrigation, the staff controls the operation of the hydraulic cylinder to generate a pulling force on the elastic telescopic rod. The elastic telescopic rod is no longer compressed and returns to its original position as the piston rod moves upward. During the recovery of the elastic telescopic rod, the rack plate meshes with the movable gear, causing the second drum to release the first pull rope and the second drum to wind up the third pull rope. Under its own weight, the receiving seat swings downward around the fixed rod until the other end of the receiving seat abuts against the support rod. S2: As the piston rod of the hydraulic cylinder continues to retract, the rack plate no longer meshes with the movable gear, the piston rod no longer exerts tension on the first pull rope, and the first and second slide plates drive the receiving seat to move down in the diversion channel until the bottom of the receiving seat abuts against the bottom wall of the diversion channel. S3: After the elastic telescopic rod has been restored to its original length, the hydraulic cylinder transfers the tension on the elastic telescopic rod to the gate. The gate moves upward with the elastic telescopic rod. At this time, the water in the main river enters the diversion channel through the diversion port. Floating debris in the diversion channel is intercepted by the material blocking seat, while non-floating debris is intercepted by the material receiving seat. The filtered water is used for irrigation, and the filtered water enters the working pipe through the connecting channel, so that the water level in the working pipe is the same as the water level in the diversion channel. S4: When it is necessary to stop the irrigation, the piston rod of the hydraulic cylinder drives the gate to move down through the elastic telescopic rod, so that the gate blocks the diversion port. After the gate abuts against the bottom wall of the diversion port, the piston rod of the hydraulic cylinder continues to move down and squeezes the elastic telescopic rod. When the piston rod moves down, it applies a pulling force to the first and second sliding plates through the first pull rope, so that the first and second sliding plates drive the receiving seat to move up and be on the upper side of the diversion channel. S5: Subsequently, the rack plate on the piston rod meshes with the movable gear on the rotating rod, and the rotating rod drives the first drum and the second drum to rotate. The first drum winds up the second pull rope, and the second drum releases the third pull rope. When the second pull rope is wound up, it pulls the receiving seat upward, causing the receiving seat to rotate around the fixed rod. The receiving seat drives the blocking seat to flip, causing the debris on the receiving seat and the blocking seat to slide down and fall off. When the third pull rope is released, the piston block slides inside the working pipe under the push of the elastic element. The piston block squeezes the water at the bottom of the working pipe, and the water in the working pipe is discharged into the first slide plate through the drain pipe. The water in the first slide plate impacts the rotating baffle seat through the spray nozzle, causing the debris that is not easy to fall off the baffle seat to be impacted and fall into the receiving seat. As the impact water falls into the receiving seat, the mud and debris in the receiving seat slide down quickly. The debris that slides down enters the debris trough along the guide surface.

[0015] Compared with the prior art, the present invention provides a water diversion device and method for water conservancy projects, which has the following beneficial effects: 1. The water diversion device and its diversion method of this water conservancy project drive the lifting component to operate when the gate mechanism is running, so that the receiving part can automatically receive the debris that enters the diversion channel with the water flow and automatically clean up the received debris. This realizes the automatic collection and cleaning of debris that enters the diversion channel during irrigation, reduces the workload and intensity of subsequent staff, avoids the diversion channel from being blocked, and ensures the diversion effect and flow stability of the subsequent diversion channel.

[0016] 2. The diversion device and diversion method of this water conservancy project, by movably connecting the material blocking seat and the material receiving seat, allows the material blocking seat to move freely in the vertical direction of the diversion channel with the help of the buoyancy of the movable floating plate, so that the material blocking seat can always automatically intercept floating debris on the water surface without the need for manual adjustment of the position of the material blocking seat according to the water level of the diversion channel. The operation is simple and quick, reducing the workload and labor intensity of subsequent staff.

[0017] 3. The water diversion device and its diversion method of this water conservancy project squeeze the water at the bottom of the working pipe by the piston block. The water in the working pipe is discharged into the first slide plate through the drain pipe. The water in the first slide plate impacts the rotating material blocking seat through the water spray nozzle, causing the debris that is not easy to fall off the material blocking seat to be impacted and fall into the receiving seat. As the impacting water falls into the receiving seat, the mud and debris in the receiving seat slide down quickly, ensuring the cleaning effect of the debris in the receiving section.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Refer to Figure 1 , Figure 3 , Figure 6 and Figure 9 A water diversion device for a water conservancy project, comprising a main river channel 1, and further comprising: Diversion channel 2 is located on the side of the main river channel 1, and a diversion outlet 4 connected to the diversion channel 2 is opened on the main river channel 1. Gate mechanism 3 is installed on the main river channel 1 and is located on the upper side of the diversion outlet 4. The receiving section is located at one end of the diversion channel 2 near the main channel 1. The receiving section includes a receiving seat 5 and a material blocking seat 6 connected to the receiving seat 5. Among them, the diversion channel 2 is equipped with a lifting component connected to the receiving part, and the lifting component is connected to the gate mechanism 3.

[0023] Specifically, the diversion channel 2 diverts water from the main river channel 1 through the diversion port 4. When the gate mechanism 3 operates, it drives the lifting component to automatically collect debris entering the diversion channel 2 with the water flow or automatically clean up the collected debris. Floating debris entering the diversion channel 2 is intercepted by the baffle seat 6, while non-floating debris is intercepted by the receiving seat 5. This achieves automatic collection and cleaning of debris entering the diversion channel 2 during irrigation, reducing the workload and intensity of subsequent staff, preventing the diversion channel 2 from being blocked, and ensuring the diversion effect and stable water flow of the subsequent diversion channel 2.

[0024] Example 2: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A water diversion device for a water conservancy project, based on embodiment 1, further includes a gate mechanism 3 comprising a first gantry frame 301 fixed to the top of the main river channel 1, two hydraulic cylinders 302 fixed to the first gantry frame 301, an elastic telescopic rod 303 connected to the piston rod 3021 of the hydraulic cylinders 302, and a gate plate 304 disposed at the bottom of the elastic telescopic rod 303, the gate plate 304 being slidably connected to the inner wall of the diversion port 4.

[0025] Furthermore, the lifting assembly includes a first sliding plate 7 and a second sliding plate 8 that are slidably connected to both sides of the inner wall of the diversion channel 2. The bottom of the second sliding plate 8 is fixed with a support rod 801 for supporting the receiving seat 5. The bottom of the first sliding plate 7 is fixed with a fixing rod 701 that is rotatably connected to the receiving seat 5. The piston rods 3021 of the two hydraulic cylinders 302 are each provided with a first pull rope 10. One of the first pull ropes 10 is connected to the first sliding plate 7, and the other first pull rope 10 is connected to the second sliding plate 8.

[0026] Specifically, during irrigation, the hydraulic cylinder 302 is controlled to pull the elastic telescopic rod 303. The elastic telescopic rod 303 is no longer compressed and returns to its original position as the piston rod 3021 moves upward. As the piston rod 3021 of the hydraulic cylinder 302 continues to contract, the piston rod 3021 no longer pulls the first pull rope 10. The first slide plate 7 and the second slide plate 8 drive the receiving seat 5 to move downward in the diversion channel 2 until the bottom of the receiving seat 5 abuts against the bottom wall of the diversion channel 2. After the elastic telescopic rod 303 has returned to its original length, the hydraulic cylinder 302 transfers the pulling force on the elastic telescopic rod 303 to the gate plate 304. The gate plate 304 moves upward with the elastic telescopic rod 303. At this time, the water in the main river channel 1 enters the diversion channel 2 through the diversion port 4. Floating debris entering the diversion channel 2 is intercepted by the intercepting seat 6, and non-floating debris is intercepted by the receiving seat 5. The filtered water is used for irrigation. When irrigation needs to be stopped, the piston rod 3021 of the hydraulic cylinder 302 drives the gate 304 to move down through the elastic telescopic rod 303, so that the gate 304 blocks the diversion port 4. After the gate 304 abuts against the bottom wall of the diversion port 4, the piston rod 3021 of the hydraulic cylinder 302 continues to move down and squeezes the elastic telescopic rod 303. When the piston rod 3021 moves down, it applies a pulling force to the first slide plate 7 and the second slide plate 8 through the first pull rope 10, so that the first slide plate 7 and the second slide plate 8 drive the receiving seat 5 to move up and be on the upper side of the diversion channel 2.

[0027] Example 3: Reference Figure 1 , Figure 3 and Figure 6 A water diversion device for a water conservancy project, based on embodiment 2, further includes a second gantry 9 fixedly installed on the diversion channel 2, and a first pull rope 10 slidably connected to the second gantry 9.

[0028] Specifically, by setting up a second gantry 9, the force direction of the first pull rope 10 can be guided, and a pulley that contacts the first pull rope 10 can be installed inside the second gantry 9. The first pull rope 10 is made of wear-resistant material.

[0029] Example 4: Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 A water diversion device for a water conservancy project, based on embodiment 3, further includes a movable groove 501 on the receiving seat 5, an elastic telescopic tube 502 fixedly installed on the inner wall of the movable groove 501, a movable float 503 fixedly installed on the top of the elastic telescopic tube 502 and slidably connected to the inner wall of the movable groove 501, and one end of the movable float 503 away from the elastic telescopic tube 502 connected to the material blocking seat 6.

[0030] Specifically, the material blocking seat 6 is movably connected to the material receiving seat 5. The material blocking seat 6 can move freely in the vertical direction of the diversion channel 2 with the help of the buoyancy of the movable float 503, so that the material blocking seat 6 can always automatically intercept floating debris on the water surface. There is no need to manually adjust the position of the material blocking seat 6 according to the water height of the diversion channel 2. The operation is simple and quick, reducing the workload and labor intensity of subsequent staff.

[0031] Example 5: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 and Figure 10 A water diversion device for a water conservancy project, based on embodiment 4, further includes a rotating rod 11 rotatably connected between the first gantry 301 and the second gantry 9. The rotating rod 11 is equipped with a first drum 111 and a movable gear 112. The piston rod 3021 of one of the hydraulic cylinders 302 is equipped with a rack plate 12 that meshes with the movable gear 112. A second pull rope 1111 is wound and connected to the first drum 111. The end of the second pull rope 1111 away from the first drum 111 is connected to the receiving seat 5.

[0032] Specifically, during irrigation, the hydraulic cylinder 302 is controlled to generate a pulling force on the elastic telescopic rod 303. The elastic telescopic rod 303 is no longer compressed and returns to its original position as the piston rod 3021 moves upward. During the recovery of the elastic telescopic rod 303, the rack plate 12 meshes with the movable gear 112, causing the second drum 113 to release the first pull rope 10. Under its own weight, the receiving seat 5 swings downward around the fixed rod 701 until the other end of the receiving seat 5 abuts against the support rod 801, which facilitates the subsequent sliding of the receiving part in the diversion channel 2. When irrigation needs to be stopped, the piston rod 3021 of the hydraulic cylinder 302 drives the gate 304 to move downward via the elastic telescopic rod 303, blocking the diversion port 4. After the gate 304 abuts against the bottom wall of the diversion port 4, the piston rod 3021 of the hydraulic cylinder 302 continues to move downward and compresses the elastic telescopic rod 303. When the piston rod 3021 moves downward, it applies a pulling force to the first sliding plate 7 and the second sliding plate 8 through the first pull rope 10, causing the first sliding plate 7 and the second sliding plate 8 to move together. The material seat 5 moves upward and is positioned above the diversion channel 2. Subsequently, the rack plate 12 on the piston rod 3021 meshes with the movable gear 112 on the rotating rod 11, and the rotating rod 11 drives the first drum 111 to rotate. The first drum 111 winds up the second pull rope 1111. When the second pull rope 1111 is wound up, it pulls the receiving seat 5 upward, causing the receiving seat 5 to rotate around the fixed rod 701. The receiving seat 5 drives the blocking seat 6 to flip, causing the debris on the receiving seat 5 and the blocking seat 6 to slide down and fall off.

[0033] Example 6: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A water diversion device for a water conservancy project, based on embodiment 5, further includes a working pipe 13 fixedly installed on the outside of the diversion channel 2, a connecting groove 131 between the working pipe 13 and the diversion channel 2, a drain pipe 132 installed at the bottom of the working pipe 13, a one-way valve installed on the drain pipe 132, and the end of the drain pipe 132 away from the working pipe 13 connected to the first slide plate 7. The first slide plate 7 has a cavity connected to the drain pipe 132, and a plurality of spray nozzles 702 connected to the cavity are opened on the outside of the first slide plate 7.

[0034] Furthermore, a second drum 113 is provided on the rotating rod 11, and a third pull rope 1131 is wound and connected to the second drum 113. The end of the third pull rope 1131 away from the second drum 113 passes through the working tube 13 and is connected to a piston block 133. The piston block 133 is slidably connected inside the working tube 13, and an elastic element 134 is provided between the piston block 133 and the inner wall of the working tube 13.

[0035] Furthermore, the diversion channel 2 has a guide surface 14 on its side wall for debris to fall, and a debris trough 15 is provided on one side of the guide surface 14.

[0036] Specifically, when irrigation needs to be stopped, the piston rod 3021 of the hydraulic cylinder 302 drives the gate 304 to move downward via the elastic telescopic rod 303, blocking the diversion port 4. After the gate 304 abuts against the bottom wall of the diversion port 4, the piston rod 3021 of the hydraulic cylinder 302 continues to move downward and presses against the elastic telescopic rod 303. When the piston rod 3021 moves downward, it applies tension to the first slide plate 7 and the second slide plate 8 through the first pull rope 10, causing the first slide plate 7 and the second slide plate 8 to move the receiving seat 5 upward and onto the upper side of the diversion channel 2. Subsequently, the rack plate 12 on the piston rod 3021 meshes with the movable gear 112 on the rotating rod 11, and the rotating rod 11 drives the second drum 113. Rotation causes the second drum 113 to release the third pull rope 1131. When the third pull rope 1131 is released, the piston block 133 slides inside the working tube 13 under the push of the elastic element 134. The piston block 133 squeezes the water at the bottom of the working tube 13. The water in the working tube 13 is discharged into the first slide plate 7 through the drain pipe 132. The water in the first slide plate 7 impacts the rotating material blocking seat 6 through the spray nozzle 702, causing the debris that is not easy to fall off the material blocking seat 6 to be impacted and fall into the receiving seat 5. As the impact water falls into the receiving seat 5, the mud and debris in the receiving seat 5 slide down quickly, ensuring the cleaning effect of the debris in the receiving part. The debris that slides down enters the debris trough 15 along the guide surface 14.

[0037] This invention also discloses a diversion method for a water diversion device in a water conservancy project, comprising the following steps: S1: When diverting water for irrigation, the staff controls the operation of the hydraulic cylinder 302, so that the hydraulic cylinder 302 generates a pulling force on the elastic telescopic rod 303. The elastic telescopic rod 303 is no longer compressed and returns to its original position as the piston rod 3021 moves upward. During the recovery of the elastic telescopic rod 303, the rack plate 12 meshes with the movable gear 112, so that the second drum 113 releases the first pull rope 10 and the second drum 113 winds up the third pull rope 1131. Under its own weight, the receiving seat 5 swings downward with the fixed rod 701 as the center until the other end of the receiving seat 5 abuts against the support rod 801. S2: As the piston rod 3021 of the hydraulic cylinder 302 continues to retract, the rack plate 12 no longer meshes with the movable gear 112, the piston rod 3021 no longer exerts tension on the first pull rope 10, and the first slide plate 7 and the second slide plate 8 drive the receiving seat 5 to move down in the diversion channel 2 until the bottom of the receiving seat 5 abuts against the bottom wall of the diversion channel 2. S3: After the elastic telescopic rod 303 has been restored to its original length, the hydraulic cylinder 302 transfers the pulling force on the elastic telescopic rod 303 to the gate 304. The gate 304 moves upward with the elastic telescopic rod 303. At this time, the water in the main river channel 1 enters the diversion channel 2 through the diversion port 4. The floating debris in the diversion channel 2 is intercepted by the material blocking seat 6, and the non-floating debris is intercepted by the material receiving seat 5. The filtered water is used for irrigation, and the filtered water enters the working pipe 13 through the connecting groove 131, so that the water level in the working pipe 13 is the same as the water level in the diversion channel 2. S4: When it is necessary to stop the irrigation, the piston rod 3021 of the hydraulic cylinder 302 drives the gate 304 to move down through the elastic telescopic rod 303, so that the gate 304 blocks the diversion port 4. After the gate 304 abuts against the bottom wall of the diversion port 4, the piston rod 3021 of the hydraulic cylinder 302 continues to move down and squeezes the elastic telescopic rod 303. When the piston rod 3021 moves down, it applies a pulling force to the first slide plate 7 and the second slide plate 8 through the first pull rope 10, so that the first slide plate 7 and the second slide plate 8 drive the receiving seat 5 to move up and be on the upper side of the diversion channel 2. S5: Subsequently, the rack plate 12 on the piston rod 3021 meshes with the movable gear 112 on the rotating rod 11, and the rotating rod 11 drives the first drum 111 and the second drum 113 to rotate. The first drum 111 winds up the second pull rope 1111, and the second drum 113 releases the third pull rope 1131. When the second pull rope 1111 is wound up, it pulls the receiving seat 5 upward, causing the receiving seat 5 to rotate around the fixed rod 701. The receiving seat 5 drives the blocking seat 6 to flip, causing the debris on the receiving seat 5 and the blocking seat 6 to slide down and fall off. When the third pull rope 1131 is released, the piston block 133 slides inside the working pipe 13 under the push of the elastic element 134. The piston block 133 squeezes the water at the bottom of the working pipe 13, and the water in the working pipe 13 is discharged into the first slide plate 7 through the drain pipe 132. The water in the first slide plate 7 impacts the rotating material blocking seat 6 through the spray nozzle 702, causing the debris that is not easy to fall off the material blocking seat 6 to be impacted and fall into the receiving seat 5. As the impact water falls into the receiving seat 5, the mud and debris in the receiving seat 5 slide down quickly. The debris that slides down enters the debris trough 15 along the guide surface 14.

The piston block (133) is slidably connected inside the working tube (13), and an elastic element (134) is provided between the piston block (133) and the inner wall of the working tube (13).

9. A water diversion device for a water conservancy project according to claim 8, characterized in that, The diversion channel (2) has a guide surface (14) on its side wall for debris to fall, and a debris trough (15) is provided on one side of the guide surface (14) of the diversion channel (2).

10. A diversion method for a water diversion device in a water conservancy project according to claim 9, characterized in that, Includes the following steps: S1: When diverting water for irrigation, the staff controls the operation of the hydraulic cylinder (302) so that the hydraulic cylinder (302) generates a pulling force on the elastic telescopic rod (303). The elastic telescopic rod (303) is no longer compressed and recovers as the piston rod (3021) moves upward. During the recovery of the elastic telescopic rod (303), the rack plate (12) meshes with the movable gear (112), so that the second drum (113) releases the first pull rope (10) and the second drum (113) winds up the third pull rope (1131). The receiving seat (5) swings downward with the fixed rod (701) as the center under its own gravity until the other end of the receiving seat (5) abuts against the support rod (801). S2: As the piston rod (3021) of the hydraulic cylinder (302) continues to retract, the rack plate (12) no longer meshes with the movable gear (112), the piston rod (3021) no longer exerts tension on the first pull rope (10), and the first slide plate (7) and the second slide plate (8) drive the receiving seat (5) to move down in the diversion channel (2) until the bottom of the receiving seat (5) abuts against the bottom wall of the diversion channel (2); S3: After the elastic telescopic rod (303) has been restored to its original length, the hydraulic cylinder (302) transfers the pulling force on the elastic telescopic rod (303) to the gate (304). The gate (304) moves up with the elastic telescopic rod (303). At this time, the water in the main channel (1) enters the diversion channel (2) through the diversion port (4). The floating debris in the diversion channel (2) is intercepted by the material blocking seat (6), and the non-floating debris is intercepted by the material receiving seat (5). The filtered water is used for irrigation, and the filtered water enters the working pipe (13) through the connecting groove (131), so that the water height in the working pipe (13) is the same as the water height in the diversion channel (2). S4: When it is necessary to stop the irrigation, the piston rod (3021) of the hydraulic cylinder (302) drives the gate (304) to move down through the elastic telescopic rod (303), so that the gate (304) blocks the diversion port (4). After the gate (304) abuts against the bottom wall of the diversion port (4), the piston rod (3021) of the hydraulic cylinder (302) continues to move down and squeezes the elastic telescopic rod (303). When the piston rod (3021) moves down, it applies a pulling force to the first slide plate (7) and the second slide plate (8) through the first pull rope (10), so that the first slide plate (7) and the second slide plate (8) drive the receiving seat (5) to move up and be on the upper side of the diversion channel (2). S5: Subsequently, the rack plate (12) on the piston rod (3021) meshes with the movable gear (112) on the rotating rod (11), and the rotating rod (11) drives the first drum (111) and the second drum (113) to rotate. The first drum (111) winds up the second pull rope (1111), and the second drum (113) releases the third pull rope (1131). When the second pull rope (1111) is wound up, it pulls the receiving seat (5) upward, causing the receiving seat (5) to rotate around the fixed rod (701) as the center. The receiving seat (5) drives the blocking seat (6) to flip, causing the debris on the receiving seat (5) and the blocking seat (6) to slide down and fall off. When the third pull rope (1131) is released, the piston block (133) slides in the working tube (13) under the push of the elastic element (134). The piston block (133) squeezes the water at the bottom of the working tube (13). The water in the working tube (13) is discharged into the first slide plate (7) through the drain pipe (132). The water in the first slide plate (7) impacts the rotating material blocking seat (6) through the spray nozzle (702), causing the debris that is not easy to fall off the material blocking seat (6) to be impacted and fall into the receiving seat (5). As the impact water falls into the receiving seat (5), the mud and debris in the receiving seat (5) slide down quickly. The debris after sliding down enters the debris trough (15) along the guide surface (14).
