[0018] By adopting the above technical solution, the present invention can intercept impurities in the water through the filter plate embedded in the side wall of the gate seat, ensuring the water quality of the diverted water and reducing damage to downstream irrigation equipment; at the same time, the collection box that slides and fits next to the filter plate can collect impurities in a timely manner, and the drive components on both sides of the canal can raise and lower the collection box to a position that is easy to clean as needed, making operation convenient and reducing maintenance difficulty.
[0019] In this invention, multiple water outlets on the other side wall of the gate seat, in conjunction with the corresponding gate plates inside, can flexibly and precisely control the opening and closing of each water outlet and the water flow size according to the water demand of different farmland areas, with the help of the lifting components on the top of the gate seat.

[0026] 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.
[0027] Please see Figure 1-3 A farmland irrigation diversion device includes a gate seat 1 fixedly installed between the inner walls of both sides of a canal. The gate seat 1 has a hollow internal structure. A filter plate 2 is embedded in one side wall of the gate seat 1. A collection box 3 is slidably attached to the side of the filter plate 2 away from the gate seat 1. A drive assembly 4 for driving the collection box 3 to move up and down is also provided on the inner walls of both sides of the canal. At least two water outlets 5 are opened through the other side wall of the gate seat 1. A gate plate 6 is slidably installed inside the gate seat 1 corresponding to the position of each water outlet 5. A lifting assembly 7 is provided on the top of the gate seat 1 to drive each gate plate 6 to move up and down to control the opening and closing of the corresponding water outlet 5.
[0028] This design ensures that, firstly, the hollow gate seat 1 fixed to the inner wall on both sides of the canal can effectively resist the impact of water flow by means of high-strength concrete pouring and pre-embedded metal connectors, providing reliable support for the internal components and ensuring long-term stable operation.
[0029] Secondly, the filter plate 2 embedded in the side wall of the gate seat 1 can intercept impurities in the water, ensure the quality of the diverted water, and reduce damage to downstream irrigation equipment; at the same time, the collection box 3 that slides and fits next to the filter plate 2 can collect impurities in time, and the drive components 4 on both sides of the canal can raise and lower the collection box 3 to a position that is easy to clean as needed, making operation convenient and reducing maintenance difficulty.
[0030] Furthermore, the multiple outlets 5 on the other side wall of the gate seat 1, together with the corresponding gate plates 6 inside, can flexibly and precisely control the opening and closing of each outlet 5 and the water flow size according to the water demand of different farmland areas, with the help of the lifting components 7 on the top of the gate seat 1. This greatly improves the rationality of water resource allocation and irrigation efficiency, and meets the diverse irrigation needs of farmland.
[0031] The drive assembly 4 includes two mounting boxes 41 that are symmetrically fixed on the inner wall of the canal, and each mounting box 41 is arranged parallel to the filter plate 2.
[0032] The two mounting boxes 41 each have a through-hole groove 42 on their opposite sidewalls, and the through-hole groove 42 is arranged along the height direction of the mounting box 41.
[0033] Each of the mounting boxes 41 is rotatably equipped with a screw 43. The top end of the screw 43 passes through the mounting box 41 and is connected to the first drive motor 45. Each screw 43 is threaded with a screw sleeve 44. One end of the screw sleeve 44 slides through the movable groove 42 and is fixedly connected to the collection box 3.
[0034] With this design, firstly, the first drive motor 45 drives the screw 43 to rotate. Utilizing the principle of threaded transmission, the screw sleeve 44 will smoothly rise or fall along the axial direction of the screw 43. Moreover, since the threaded transmission has high precision, it can accurately control the lifting height of the collection box 3. Thus, when it is necessary to clean the collection box 3, it can be accurately lifted to a suitable height, making it convenient for operators to carry out cleaning work.
[0035] Secondly, the two mounting boxes 41 are symmetrically fixed to the inner wall of the canal and are set parallel to the filter plate 2. This symmetrical structure allows the collection box 3 to be subjected to a uniform force during the lifting and lowering process, avoiding tilting or shaking. The movable groove 42 not only provides guidance for the movement of the screw sleeve 44, but also ensures a tight fit between the screw sleeve 44 and the mounting box 41, further enhancing the stability of the overall structure. Thus, even when the water flow in the canal is rapid, the collection box 3 can still be lifted and lowered stably, ensuring the reliable operation of the device.
[0036] Furthermore, the mounting box 41 encloses the transmission components such as the screw 43, which on the one hand prevents water flow, silt and other impurities in the river and canal from corroding and damaging the transmission components, thus extending their service life; on the other hand, when maintenance or repair of the drive assembly 4 is required, the components inside the mounting box 41 can be directly inspected and replaced, making the operation relatively simple; moreover, the first drive motor 45 is installed outside the mounting box 41, making it convenient for maintenance personnel to debug, repair and maintain it, reducing maintenance costs and difficulty.
[0037] Finally, since the rotational speed and direction of the screw 43 can be adjusted by controlling the first drive motor 45, the drive assembly 4 can adapt to different working scenarios and needs. This allows for faster lifting and lowering of the collection box 3 when water levels fluctuate significantly or when rapid removal of large amounts of impurities is required. Furthermore, when high positional accuracy of the collection box 3 is required, the motor speed can be fine-tuned for more precise positioning. This flexibility enables the farmland irrigation diversion device to better cope with complex and changing farmland irrigation and water management conditions.
[0038] In this embodiment, the first drive motor 45 is a waterproof DC servo motor produced by Ganzhou Shengfu Motor Co., Ltd. or a waterproof geared motor produced by Shanghai Taixing Transmission Technology Co., Ltd.
[0039] The working principle and installation method of the first drive motor 45 are existing technologies and are known to those skilled in the art, so they will not be described in detail in this embodiment.
[0040] The top of the gate seat 1 is fixedly connected to a support frame 8 that is in the shape of an inverted U, and the lifting components 7 are all installed on the support frame 8.
[0041] This design ensures that, firstly, the inverted U-shaped support frame 8 has a stable structure, providing a solid and reliable installation foundation for the lifting assembly 7. Thus, in farmland irrigation environments, where there are many factors such as water flow impact and equipment vibration, the support frame 8 can effectively resist these external forces, preventing the lifting assembly 7 from shifting or being damaged, and ensuring its stable operation.
[0042] The lifting assembly 7 includes a take-up roller 71, with fixed plates 72 rotatably mounted at both ends of the take-up roller 71. The bottoms of the two fixed plates 72 are fixedly connected to the support frame 8. A second drive motor 73 is drivenly connected to one end of the take-up roller 71, and the second drive motor 73 is fixedly mounted on the support frame 8.
[0043] A steel cable 74 is wound on the take-up roller 71, and the free ends of the steel cable 74 all pass through the top of the support frame 8 and are fixedly connected to the corresponding gate plate 6.
[0044] With this design, firstly, the second drive motor 73 is directly connected to the winding roller 71, which can quickly and efficiently transmit power to the winding roller 71. Thus, when it is necessary to control the raising and lowering of the gate 6, the second drive motor 73 is started, which quickly drives the winding roller 71 to rotate, realizing the winding and unwinding of the steel cable 74. This allows for rapid adjustment of the height of the gate 6, timely response to the control needs of farmland irrigation for water flow size and on / off, and improvement of the overall operating efficiency of the diversion device.
[0045] Secondly, by controlling the forward and reverse rotation and speed of the second drive motor 73, the length of the take-up and unwinding of the steel cable 74 by the take-up roller 71 can be precisely adjusted, thereby precisely controlling the lifting height of the gate 6. This allows for precise adjustment of the water flow at the outlet 5 according to the actual water demand of different farmland areas, achieving precise irrigation, avoiding water waste, and improving the efficiency of water resource utilization.
[0046] Furthermore, the fixing plates 72 at both ends of the take-up roller 71 are fixedly connected to the support frame 8, providing a stable support structure for the take-up roller 71. Thus, during the frequent rotation of the take-up roller 71 driven by the motor, the fixing plates 72 can effectively prevent the take-up roller 71 from shaking or shifting, ensuring the stable operation of the entire lifting assembly 7. At the same time, the steel cable 74 has high strength and wear resistance, and can withstand the weight of the gate plate 6 and the tension during the lifting process, ensuring long-term stable operation and reducing the probability of failure.
[0047] In this embodiment, the second drive motor 73 is a waterproof DC servo motor produced by Ganzhou Shengfu Motor Co., Ltd.
[0048] The working principle and installation method of the second drive motor 73 are existing technologies and are known to those skilled in the art, so they will not be described in detail in this embodiment.
[0049] The surface of the collection box 3 is evenly provided with multiple water-permeable holes, and the diameter of the water-permeable holes is 0.1mm-0.2mm.
[0050] With this design, firstly, when the collection box 3 intercepts the impurities filtered out by the filter plate 2, the water flow can pass through quickly due to the presence of water permeable holes, making it easier for the impurities to settle and accumulate in the collection box 3, preventing the impurities from drifting around with the water flow, thus collecting various types of garbage more efficiently and improving the collection box 3's ability to capture garbage.
[0051] Secondly, the water flows out through the permeable holes, which can effectively prevent garbage from accumulating and clogging at the inlet of the collection box 3, ensure that the water flow continuously washes the filter plate 2, maintains the filtration efficiency, keeps the water flow circulation of the entire diversion device smooth, and ensures the stable operation of the water system.
[0052] Furthermore, when cleaning collection box 3, since the water has been drained through the permeable holes, the garbage inside the box will not stick together due to water accumulation, but will become loose and easy to clean. As a result, the staff can more easily clean the garbage out of collection box 3, reducing the amount of cleaning work and improving maintenance efficiency.
[0053] Finally, preventing water from accumulating in the collection box 3 for a long time reduces the corrosion and wear of the collection box 3 caused by garbage; at the same time, the smooth flow of water also reduces the water pressure on the collection box 3, thereby extending the service life of the collection box 3 and reducing the maintenance cost of the device.
[0054] A diversion plate 9 is provided between each of the two adjacent outlets 5. One end of the diversion plate 9 is fixedly connected to the gate seat 1, and the bottom of the diversion plate 9 is fixedly connected to the bottom of the river channel.
[0055] This design allows the diversion plate 9 to guide and distribute the water flowing from the gate seat 1 according to the needs of different outlets 5. Thus, when different farmland areas have different water requirements, the diversion plate 9 can change the direction and flow rate of the water flow, making the water flowing out of each outlet 5 more in line with the irrigation requirements of the corresponding area, avoiding water flow from concentrating at a certain outlet 5, and improving the balance and accuracy of water resource distribution.
[0056] Furthermore, during the process of water flowing from gate seat 1 to outlet 5, the diversion plate 9 acts as a buffer and disperses the impact force of the water flow, reducing the direct impact of the water flow on gate seat 1, outlet 5 and the bottom of the canal, reducing the risk of damage to these parts due to long-term water flow scouring, and extending the service life of the device and the canal.
[0057] Finally, the diversion plate 9 is connected to the gate seat 1 at one end and fixed to the bottom of the canal at the other end, forming a stable support structure between the two. This helps the gate seat 1 resist the pressure of the water flow when the water flow is rapid, preventing the gate seat 1 from being displaced or shaking due to the impact of the water flow, and improving the structural stability of the entire device under complex hydraulic conditions.
[0058] Silicone brushes are evenly arranged on the inner wall of the movable groove 42.
[0059] With this design, firstly, the screw sleeve 44 slides up and down frequently in the movable groove 42, and mud and impurities in the river can easily adhere to it. The silicone brush can continuously wipe its surface during the sliding process of the screw sleeve 44, effectively removing the attached impurities, preventing impurities from entering the thread gap, ensuring smooth transmission between the screw sleeve 44 and the screw 43, avoiding jamming caused by impurity wear, and ensuring that the collection box 3 rises and falls smoothly.
[0060] Secondly, after prolonged use, the friction between the screw sleeve 44 and the inner wall of the movable groove 42 may cause wear and scratches on the inner wall, affecting the structural stability. The brush can act as a buffer, reducing the direct scraping of the inner wall of the movable groove 42 by the screw sleeve 44, extending the service life of the movable groove 42, maintaining the integrity of the overall structure of the drive assembly 4, and reducing the maintenance cost of the device.
[0061] When in use, the water in the canal enters the gate seat 1 and first passes through the filter plate 2. The garbage in the water is intercepted by the filter plate 2, and the water continues to flow into the gate seat 1 through the filter plate 2. At this time, the collection box 3 is in the initial position, located below the filter plate 2, and is used to receive the impurities intercepted by the filter plate 2.
[0062] As impurities accumulate on the filter plate 2, when it is necessary to clean the collection box 3 or clean the garbage attached to the filter plate 2, the first drive motor 45 is started. The first drive motor 45 drives the screw 43 to rotate. Since the screw sleeve 44 is threadedly connected to the screw 43, and one end of the screw sleeve 44 passes through the movable groove 42 and is fixed to the filter plate 2 (and the connected collection box 3), the rotation of the screw 43 causes the screw sleeve 44 to move upward along the movable groove 42, thereby driving the collection box 3 to rise. At the same time, during the rising process, the silicone brush on the inner side wall of the movable groove 42 cleans the surface of the screw sleeve 44 to prevent impurities such as mud and sand from adhering to the screw sleeve 44 and affecting the transmission.
[0063] When the collection box 3 rises to a position easy to clean, the first drive motor 45 is stopped, and the staff cleans the collection box 3. After cleaning, the first drive motor 45 is restarted to lower the collection box 3 back to the initial position to continue collecting impurities. During this process, the tiny water-permeable holes on the surface of the collection box 3 allow water to flow back into the canal in a timely manner, reducing the weight of the collection box 3 and facilitating lifting and lowering operations.
[0064] When irrigation water needs to be supplied to farmland, the second drive motor 73 is controlled to operate according to the water demand of different farmland areas. The second drive motor 73 drives the winding roller 71 to rotate, and the winding roller 71 winds up and unwinds the steel cable 74, thereby controlling the lifting height of the gate 6. Thus, when it is necessary to increase the water flow of a certain outlet 5, the corresponding second drive motor 73 rotates forward, the winding roller 71 winds up the steel cable 74, pulls the gate 6 up, increases the opening degree of the outlet 5, and increases the water flow; conversely, the motor reverses, the gate 6 descends, and reduces the water flow.
[0065] The diversion plate 9 between adjacent outlets 5 will guide and distribute the water flowing out of the gate seat 1 in a reasonable manner according to the needs of each outlet 5, so as to ensure that the water flows evenly to each outlet 5 and meet the irrigation needs of different farmland areas.
[0066] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
