Description

Technical Field

[0001] The invention relates to the field of farmland water conservancy projects, in particular to an irrigation channel gate. Background Art

[0002] Irrigation channel gates, as key components of farmland water conservancy systems, fulfill crucial functions such as controlling water flow, regulating water levels, and allocating water resources. Their performance directly impacts irrigation efficiency and water resource utilization. In modern agricultural irrigation systems, adjusting the gate position through control components enables the rational allocation of water resources, ensuring on-demand water supply to farmland. This is crucial for improving agricultural production efficiency and promoting the development of water-saving irrigation technologies.

[0003] Currently, most irrigation channel gates and sluice gates widely used in the market adopt a straight design. Although this traditional structure is simple in construction and easy to manufacture and install, in practice, because the straight gate is perpendicular to the direction of water flow, the pressure of water impacting the gate cannot be effectively dispersed, resulting in concentrated and high water pressure on the gate. Under long-term high water pressure, the gate and its supporting structure are prone to fatigue damage, deformation, and even rupture. This not only shortens the service life of the gate and increases maintenance costs, but can also cause water leakage and difficulty in opening and closing, affecting the stable operation of the irrigation system and making it difficult to meet the requirements of modern agriculture for efficient and safe irrigation facilities. Summary of the Invention

[0004] In view of the above problems, an irrigation channel gate provided in an embodiment of the present application divides the gate into a three-section structure.

[0018] Compared with the prior art, an irrigation channel gate provided by an embodiment of the present invention has the following beneficial effects: 1.

[0019] 2. When performing irrigation and drainage, the present invention divides the gate plate into a three-section combination structure consisting of an arc-shaped plate and rotatable baffles on both sides. The curved surface of the arc-shaped plate disperses the water flow pressure to different areas along the arc surface. When the baffles on both sides rotate, they can guide the direction of the water flow to avoid concentrated impact of the water flow.

[0021] 4. The present invention is provided with a support mechanism, a telescopic part and a pressure-resistant component. When draining a small amount of water, the water pressure on the arc plate increases due to the rotation of the baffle. When the baffle rotates, the connecting rod and the slide plate can be used to enable the extrusion rod to squeeze the reset spring 2. The reverse elastic force generated by squeezing the reset spring 2 can form a supporting force for the arc plate through the connecting rod and the rotating rod. At the same time, when the baffle rotates, the local pressure is evenly dispersed to a larger area through multiple reinforcing plates. The double support mechanism is used to make the stress distribution of the arc plate uniform when it is subjected to water flow pressure, which greatly improves the compressive strength of the gate during use and further extends the service life of the gate.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 - Figure 9 This application is described in further detail.

[0033] Please refer to Figure 1 and Figure 2, an irrigation channel gate, including a gate plate 2 arranged on the inner side of the channel 1, a lifting assembly 3 for driving the gate plate 2 to move up and down is provided on the upper part of the channel 1, the gate plate 2 includes an arc-shaped plate 21 and two baffles 22 rotatably installed on the left and right ends of the rear side of the arc-shaped plate 21, the bottoms of the arc-shaped plate 21 and the baffles 22 are in contact with the inner horizontal section of the channel 1, and driving assemblies 7 for driving the baffles 22 to rotate are provided on both the left and right sides of the upper part of the arc-shaped plate 21.

[0034] During irrigation and drainage, when large-volume drainage is required, the gate plate 2 is driven upward as a whole by the lifting component 3, and the bottom of the arc plate 21 and the baffles 22 on both sides are away from the inner horizontal section of the channel 1. At this time, large-flow drainage can be achieved. When small-volume drainage is required, the driving component 7 is used to drive the baffles 22 on both sides to rotate, and the water flow area is adjusted by controlling the rotation angle of the baffle 22 to achieve precise small-flow drainage.

[0035] At the same time, the gate plate 2 is designed as a three-section combination structure. Through the curved surface design of the arc plate 21, the water flow pressure is dispersed to different areas along the curved surface to avoid pressure concentration. The rotatable baffles 22 on both sides can guide the direction of the water flow when rotating to drain water, further reducing the direct impact force of the water flow on the gate plate 2.

[0036] See Figure 2 The lifting assembly 3 includes a gate frame 31 fixedly arranged on the upper part of the channel 1. A threaded rod 32 is rotatably provided on the inner horizontal section of the gate frame 31. The top end of the threaded rod 32 passes through the interior of the arc plate 21 and is threadedly connected to the arc plate 21. A motor 2 33 is fixedly provided on the upper part of the gate frame 31, and the output shaft of the motor 2 33 is connected to the top end of the threaded rod 32.

[0037] See Figure 7 and Figure 8 The two vertical sections inside the channel 1 are fixed with sealing plates 8, and waterstops 9 are fixed on both sides of the sealing plates 8 close to the baffle 22. The side of the waterstop 9 away from the sealing plates 8 is in close contact with the baffle 22.

[0038] See Figure 7 A guide block 10 is fixedly provided on the side of the baffle 22 close to the water stop 9, and a guide opening 11 for use with the guide block 10 is opened on the side of the sealing plate 8 close to the baffle 22. The side of the guide block 10 away from the baffle 22 passes through the guide opening 11 and contacts one side of the guide opening 11.

[0039] When large-volume drainage is required, motor 2 33 works to drive threaded rod 32 to rotate. The rotation of threaded rod 32 can drive the curved plate 21 and baffle 22 to move upward away from the inner horizontal section of channel 1. During the rising process of curved plate 21 and baffle 22, guide block 10 will slide synchronously along guide opening 11 to ensure the stability of baffle 22 and curved plate 21 during the upward movement. When curved plate 21 and baffle 22 move to appropriate positions, motor 2 33 stops working. At this time, a larger water channel is formed between the inner side of channel 1 and curved plate 21 and baffle 22. Water flow through the larger water channel can achieve large-volume drainage and meet the water requirements for irrigation. After drainage is completed, motor 2 33 works to drive curved plate 21 and baffle 22 to reset and continue to close the water flow.

[0040] See Figure 6 The drive assembly 7 includes a mounting plate 71 fixedly mounted on the side of the curved plate 21 near the channel 1. A motor 1 72 is fixedly mounted on the top of the mounting plate 71. A rotating rod 73 is rotatably mounted on the rear side of the curved plate 21. The baffle 22 is fixedly mounted on the outside of the rotating rod 73. The top end of the rotating rod 73 passes through the curved plate 21 and is rotatably connected to the inner horizontal section of the mounting plate 71. The output shaft of the motor 1 72 is connected to the top end of the rotating rod 73. A waterstop 2 12 is fixedly mounted on the side of the curved plate 21 near the baffle 22. The side of the waterstop 22 away from the curved plate 21 is in close contact with the baffle 22.

[0041] When a small amount of drainage is required, the motor 1 72 drives the rotating rod 73 to rotate counterclockwise. The counterclockwise rotation of the rotating rod 73 can drive the baffle 22 to rotate toward the side away from the channel 1, so that the baffle 22 and the sealing plate 8 are separated to form a water passage with a smaller area. The water flows through the water passage with a smaller area to achieve a small amount of drainage (such as Figure 9 As shown), during the drainage process, the curved surface design of the arc plate 21 and the rotation angle of the baffle 22 can effectively guide the water flow to pass smoothly and reduce the direct impact of the water flow on the gate 2; at the same time, the baffles 22 on both sides can independently control the rotation angle to achieve asymmetric drainage and meet the water flow distribution requirements under special working conditions. After the drainage is completed, the motor 1 72 drives the baffle 22 to rotate to the initial position. At this time, the water stop 1 9 and the water stop 2 12 are both tightly attached to the baffle 22. During this process, the driving force of the motor 1 72 to drive the arc plate 21 to rotate can overcome the water pressure of the water flow on the baffle 22, and the water flow can continue to be closed.

[0042] See Figure 1 and Figure 3A support plate 4 is fixedly provided on the rear side of the gate plate 2. Two sets of support mechanisms 5 are symmetrically arranged between the support plate 4 and the gate plate 2 to support the gate plate 2. Slide grooves are provided on both the left and right sides of the support plate 4. The support mechanism 5 includes a slide plate 51 slidably arranged in the slide groove. Two connecting rods 52 symmetrically arranged in the upper and lower directions are hingedly provided on the side of the slide plate 51 away from the slide groove. The end of the connecting rod 52 away from the slide plate 51 is hingedly connected to the baffle 22. Two sets of telescopic members 53 symmetrically arranged in the upper and lower directions are provided between the curved plate 21 and the slide plate 51.

[0043] See Figure 4 The telescopic member 53 includes a connecting sleeve 531 hingedly arranged on the rear side of the arc-shaped plate 21, an extrusion rod 532 is slidably arranged inside the connecting sleeve 531, and a return spring 2 533 connected to one end of the extrusion rod 532 is fixedly arranged inside the connecting sleeve 531. The end of the extrusion rod 532 away from the return spring 2 533 passes through the interior of the connecting sleeve 531 and is hinged to the front side of the corresponding slide plate 51.

[0044] See Figure 5 A groove is provided inside the slide 51, and a limit assembly 54 is provided in the groove to limit the use position of the slide 51. The limit assembly 54 includes two guide rods 541 fixedly arranged in the groove and symmetrically distributed up and down. A movable plate 542 is slidingly arranged between the two guide rods 541, and a return spring 543 is sleeved on the outer side of the guide rod 541. The two ends of the return spring 543 are respectively connected to the inner wall of the groove and the movable plate 542. Two limit rods 544 symmetrically distributed up and down are fixedly provided on the side of the movable plate 542 close to the support plate 4, and a magnetic block 545 is fixedly provided on the side of the movable plate 542 away from the limit rod 544. An electromagnet 546 used in conjunction with the magnetic block 545 is fixedly provided in the groove.

[0045] See Figure 5 A plurality of limiting holes 6 distributed in a linear array and connected to the slide groove are provided on both sides of the left and right sides of the support plate 4. The limiting rod 544 passes through the groove on the side away from the movable plate 542 and is plugged into the corresponding limiting hole 6.

[0046] In order to improve the compressive strength of the arc plate 21 during small-volume drainage, the electromagnet 546 works to magnetically adsorb the magnetic block 545 before the baffle 22 rotates. At this time, the magnetic block 545 will approach the electromagnet 546 and fit into the electromagnet 546. When the magnetic block 545 moves, it will drive the movable plate 542 to move in the direction of the electromagnet 546. When the movable plate 542 moves and squeezes the reset spring 543, it will drive the limit rod 544 to move out of the corresponding limit hole 6. At this time, the limit lock on the slide plate 51 is cancelled.

[0047] When the baffle 22 rotates, the connecting rod 52 pushes the slide plate 51 in the slide groove toward the direction close to the curved plate 21. After the baffle 22 rotates to a suitable angle, the slide plate 51 stops sliding, and then the electromagnet 546 stops working. The return spring 1 543 can drive the limit rod 544 to be re-inserted into the corresponding limit hole 6, so that the slide plate 51 can be re-limited and locked. At this time, a stable connection system is established between the slide plate 51, the support plate 4, the baffle 22 and the curved plate 21, and the slide plate 51 will drive the extrusion rod 532 to press the return spring 2 53 during the movement. 3 is squeezed, and the compression degree of the second return spring 533 changes after being squeezed, which generates a reverse elastic force. The generated reverse elastic force is evenly transmitted to the curved plate 21 through the squeezing rod 532, the sliding plate 51 and the connecting rod 52, thereby enhancing the rigidity of the curved plate 21. At the same time, when the elastic force of the second return spring 533 acts on the baffle 22, it generates a supporting force on the curved plate 21. When the water flow hits the curved plate 21, this supporting force can help the curved plate 21 resist the pressure of the water flow, making the curved plate 21 less likely to deform, thereby effectively improving the compressive strength of the curved plate 21.

[0048] See Figure 2 and Figure 9 The two baffles 22 are each provided with a pressure-resistant component 55 on the side close to each other to assist the curved plate 21 in resisting pressure. The pressure-resistant component 55 includes a plurality of reinforcing plates 551 fixedly arranged on the side of the curved plate 21 away from the channel 1, and the plurality of reinforcing plates 551 are distributed in a linear array on the curved plate 21.

[0049] In order to further improve the compressive strength of the curved plate 21 during small-volume drainage, when the motor 72 drives the rotating rod 73 to rotate so that the baffle 22 rotates to drain water, when the water flow hits the curved plate 21, multiple reinforcing plates 551 distributed in a linear array can disperse the pressure originally concentrated on the local part of the curved plate 21 to more areas, avoiding local damage to the curved plate 21 due to excessive pressure, making the overall force on the curved plate 21 more uniform, reducing the risk of stress concentration, further improving the compressive strength of the curved plate 21, and extending the service life of the gate plate 2.

[0050] During specific work, when irrigation and drainage are carried out, the hydrostatic pressure and dynamic impact force exerted by the water flow on the gate plate 2 are dispersed by dividing the gate plate 2 into a three-section combination structure of an arc plate 21 and rotatable baffles 22 on both sides. Then, when large-volume drainage is carried out, the gate plate 2 can be driven upward as a whole by the lifting component 3, and the bottom of the arc plate 21 and the baffles 22 on both sides are away from the inner horizontal section of the channel 1. At this time, large-flow drainage can be achieved; when small-volume drainage is required, the driving component 7 is used to drive the baffles 22 on both sides to rotate, and the water flow area is adjusted by controlling the rotation angle of the baffle 22 to achieve precise small-flow drainage.

[0051] At the same time, during the rotation of the baffle 22, the slide plate 51 can be pushed to move through the cooperation of the limit assembly 54 and the connecting rod 52. The movement of the slide plate 51 can generate a supporting force on the curved plate 21 through the cooperation of the telescopic member 53. When the water flow hits the curved plate 21, this supporting force can help the curved plate 21 resist the pressure of the water flow, making the curved plate 21 less likely to deform, thereby effectively improving the compressive strength of the curved plate 21.

[0052] Moreover, as the rotation angle of the baffle 22 gradually increases, more water flows directly impact the curved plate 21, causing the water pressure on the curved plate 21 to increase accordingly. At this time, the pressure-resistant component 55 can be used to evenly disperse the pressure originally concentrated on the curved plate 21 to a larger area, avoiding deformation of the curved plate 21 due to pressure concentration, further improving the compressive strength of the curved plate 21, and extending the service life of the gate plate 2.

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
