Description
Technical Field
[0001] This utility model belongs to the field of farmland water conservancy technology, specifically relating to a water-retaining plate for farmland irrigation. Background Technology
[0002] A water-retaining barrier for farmland irrigation is a device used to control the direction of water flow, regulate water level, or intercept water flow. It is typically installed in channels, farmland boundaries, or irrigation systems. Through its physical structure, it directly blocks water flow, changes its direction, or controls the water level. Some water-retaining barriers are equipped with adjustable devices, allowing for dynamic regulation of water flow through manual or automatic control. This enables precise irrigation, prevents soil erosion, or protects farmland from flooding. Water-retaining barriers not only precisely control water distribution, avoiding water waste and improving irrigation efficiency, but also intercept excess water during heavy rains or floods, preventing farmland from being submerged and protecting crop growth.
[0003] Chinese Patent Publication No. CN222382350U discloses a water-retaining plate for farmland irrigation, comprising a U-shaped frame with an insertion groove. A positioning plate is connected to the U-shaped frame via fixing screws. An inflatable baffle door is connected to the positioning plate, and the side area of the inflatable baffle door is not less than the side area of the U-shaped opening of the U-shaped frame. An air supply head and an air outlet head are connected to the positioning plate, and the air supply head and air outlet head are connected to the inflatable baffle door. A front filter mesh baffle and a rear filter mesh baffle are connected to the U-shaped frame. The bottom surface inside the U-shaped frame is inclined. Beneficial effects: It efficiently seals the water-retaining plate and easily and efficiently allows water to flow through it.
[0004] In practical use, this utility model is typically installed at farmland ditches or sluice gates. However, existing water-retaining barriers for farmland irrigation are mostly fixed designs, only adaptable to channels or sluice gates of specific sizes to achieve their water-retaining function. This fixed structure limits its application scenarios. When faced with ditches or sluice gates of different sizes, the water-retaining barriers are difficult to adapt due to their inflexibility, requiring frequent replacement of equipment of the corresponding specifications to meet operational needs. This limitation not only increases the cost and complexity of equipment use but also exposes its insufficient applicability in diverse farmland environments, restricting its versatility and efficiency in actual irrigation management.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Example 1:
[0029] Please see Figure 1-5 This utility model provides a water-retaining plate for farmland irrigation, comprising:
[0030] The baffle body 1 and two mounting brackets 2;
[0031] Two rectangular slots are respectively opened on both sides of the baffle body 1. Each of the two rectangular slots is provided with a matching extension plate 3. The other end of the two extension plates 3 abuts against the inner wall of the two mounting brackets 2 respectively.
[0032] A drive groove is formed inside the baffle body 1. A threaded rod 4 is provided through the drive groove. The external threads on both sides of the threaded rod 4 are arranged in opposite directions and are located in two rectangular grooves respectively.
[0033] A positioning groove is formed inside the baffle body 1. The positioning groove has a drain outlet through it. A positioning plate 5 that matches the drain outlet is provided inside the positioning groove. Filter plates 6 are provided on both sides of the drain outlet.
[0034] Specifically, such as Figure 1 and Figure 2 As shown, a fixed plate 7 is provided between the two mounting brackets 2. A cylinder 18 is provided at the bottom of the fixed plate 7. The cylinder 18 is existing technology and will not be described in detail here. The output end of the cylinder 18 is located at the upper end of the baffle body 1. A snap-fit plate 8 is provided on both sides of the fixed plate 7. A snap-fit groove adapted to the snap-fit plate 8 is opened on one side of each of the two mounting brackets 2. The two snap-fit plates 8 are located in the two snap-fit grooves respectively and are slidably connected to the side wall of the snap-fit groove. When the cylinder 18 is started, it can drive the baffle body 1 and the two extension plates 3 to move up and down, thereby controlling the opening and closing of the baffle. The snap-fit plates 8 on both sides of the fixed plate 7, in conjunction with the snap-fit grooves on both sides of the two mounting brackets 2, can flexibly adjust the position of the two mounting brackets 2 so that they can be adapted to baffles of different sizes and specifications.
[0035] Specifically, such as Figure 2 As shown, each of the two extension plates 3 has a threaded hole on one side that is compatible with the threaded rod 4. The two ends of the threaded rod 4 are located in the two threaded holes respectively and are threadedly connected to the side wall of the threaded hole.
[0036] Through its design, when the threaded rod 4 rotates, it will drive the two extension plates 3 to move respectively. When it stops rotating, it can lock the position of the extension plates 3 according to the characteristics of the threaded rod 4, so that the size and specifications of the baffle plate can be flexibly adjusted to adapt to different farmland channels or sluice gates.
[0037] Specifically, such as Figure 2 and Figure 4 As shown, a drive motor 9 is provided at the upper end of the drive groove. The drive motor 9 is existing technology and will not be described in detail here. A first bevel gear 10 is provided at the output end of the drive motor 9. A second bevel gear 11 that meshes with the first bevel gear 10 is provided on the outer side of the threaded rod 4. The output end of the drive motor 9 will drive the first bevel gear 10 and the second bevel gear 11 to rotate, thereby driving the threaded rod 4 to rotate.
[0038] Specifically, such as Figure 2 and Figure 3 As shown, each of the two extension plates 3 has a T-shaped limiting plate 12 on one side, and each of the two mounting brackets 2 has a limiting groove adapted to the limiting plate 12 on one side. The two limiting plates 12 are located in the two limiting grooves respectively and are slidably connected to the side wall of the limiting groove. The two T-shaped limiting plates 12 and the limiting groove can enable the extension plates 3 to move the mounting brackets 2 without affecting the up and down movement of the extension plates 3.
[0039] Specifically, such as Figure 3 As shown, sealing gaskets 13 are provided on both sides of the two extension plates 3. The two sealing gaskets 13 on both sides abut against the two rectangular grooves respectively. The sealing gaskets 13 can ensure the sealing of the connection between the extension plate 3 and the baffle body 1 and avoid leakage.
[0040] Specifically, such as Figure 2 and Figure 5 As shown, an electric push rod 19 is provided at the upper end of the positioning groove. The electric push rod 19 is existing technology and will not be described in detail here. The output end of the electric push rod 19 is located at the upper end of the positioning plate 5. When the electric push rod 19 is started, it will drive the positioning plate 5 to move up and down, thereby conveniently opening or closing the drain outlet.
[0041] Example 2:
[0042] Please see Figure 1-5 This utility model provides a water-retaining plate for farmland irrigation, comprising:
[0043] The baffle body 1 and two mounting brackets 2;
[0044] Two rectangular slots are respectively opened on both sides of the baffle body 1. Each of the two rectangular slots is provided with a matching extension plate 3. The other end of the two extension plates 3 abuts against the inner wall of the two mounting brackets 2 respectively.
[0045] A drive groove is formed inside the baffle body 1. A threaded rod 4 is provided through the drive groove. The external threads on both sides of the threaded rod 4 are arranged in opposite directions and are located in two rectangular grooves respectively.
[0046] A positioning groove is formed inside the baffle body 1. The positioning groove has a drain outlet through it. A positioning plate 5 that matches the drain outlet is provided inside the positioning groove. Filter plates 6 are provided on both sides of the drain outlet.
[0047] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the bottom end of the positioning groove is rotatably connected to the mounting shaft 14. Both ends of the mounting shaft 14 extend to the outside and are equipped with cleaning brushes 15. The two cleaning brushes 15 abut against one side of the two filter screens respectively. The outside of the mounting shaft 14 is provided with mounting wheels 16, and the bottom end of the positioning plate 5 is provided with a rack plate 17 that meshes with the mounting wheels 16.
[0048] Through its design, the positioning plate 5 can drive the rack plate 17 to move when it moves up and down. The rack plate 17 will drive the mounting wheel 16 and the mounting shaft 14 to rotate. The mounting shaft 14 will drive the cleaning brushes 15 on both sides to rotate, which can conveniently clean the impurities blocked on the filter plates 6 on both sides of the drain outlet, thereby ensuring the continuous smooth flow of irrigation water.
[0049] See Figure 1-5 When using a water-retaining baffle for farmland irrigation, the drive motor 9 needs to be started first, according to the size of the farmland channel or sluice gate. The output of the drive motor 9 will drive the first bevel gear 10 to rotate, which in turn will drive the second bevel gear 11 and the threaded rod 4 to rotate. The threaded rod 4 will drive the extension plates 3 on both sides to move, thereby adjusting the size of the water-retaining baffle. When it is necessary to open or close the water-retaining baffle, the baffle body 1 and the two extension plates 3 can be moved up and down by starting the cylinder 18 to open or close the baffle. Alternatively, the electric push rod 19 can be started. The output of the electric push rod 19 will drive the positioning plate 5 to move up and down, thereby opening or closing the drain outlet and opening or closing the water-retaining baffle. When the positioning plate 5 moves up and down, it will drive the rack plate 17 to move, which will drive the mounting wheel 16 and the mounting shaft 14 to rotate. This will conveniently drive the two cleaning brushes 15 to rotate and clean the two filter plates 6, avoiding the tediousness and lag of manual cleaning and preventing the reduction of drainage efficiency caused by the accumulation of impurities.
