[0026] In the following, only some exemplary embodiments are described briefly. As those skilled in the art can realize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not limiting.

[0027] As Figure 1 shown, a high-standard farmland irrigation channel structure of the present application includes a channel bottom plate 1, a transverse drainage groove 2, an adjusting pad 3, and a support column 4. These components work together to ensure the efficient operation of the irrigation system and adapt to various terrains.

[0028] The channel bottom plate 1 is laid on the farmland to form the bottom of the channel. The channel bottom plate 1 is provided with a plurality of transverse drainage grooves 2 to evenly distribute the water flowing into the channel, preventing local water flow from being too fast or too slow, thereby avoiding the problems of channel siltation or erosion caused by uneven water flow. The transverse drainage grooves 2 are distributed at equal intervals along the width direction of the channel bottom plate 1, ensuring the uniform flow of water in the channel.

[0029] The adjusting pad 3 is arranged below the channel bottom plate 1 and is mainly used to adjust the inclination angle of the channel bottom plate 1. This allows the channel bottom plate 1 to adapt to the slope requirements of different terrains, ensuring the uniformity of water flow. Specifically, the adjusting pad 3 is arranged at different positions below the channel bottom plate 1 according to the different heights of the terrain, so that the overall slope of the channel bottom plate 1 is uniform. This design can flexibly cope with complex terrain changes, improving the adaptability and stability of the irrigation system.

[0030] The support column 4 is arranged on the side wall of the channel on both sides of the adjusting pad 3 and the channel, used to support and fix the channel bottom plate 1 and maintain its structural stability. The support column 4 is fixed on the adjusting pad 3 by bolts 12, ensuring the stability of the entire channel structure. This design not only enhances the carrying capacity of the channel, but also improves its ability to resist external environmental factors, ensuring long-term stable operation.

[0031] Specifically, the channel bottom plate 1 can be made of corrosion-resistant and durable materials such as high-strength plastic or concrete. The transversely arranged drainage grooves can be formed in one piece by a mold to ensure their structural consistency and durability. The adjustment pads 3 can be customized to different heights as needed, facilitating flexible adjustment in different terrain conditions. The support columns 4 can be made of metal materials and are fixed between the ground and the adjustment pads 3 through pre-buried bolts 12, ensuring the firmness and stability of the entire structure.

[0032] The scheme of the present application aims to solve the problem of uneven local water flow caused by the difficulty of the slope of the channel bottom to completely match the actual terrain. Specifically, through the flexible use of the adjustment pads 3, the channel bottom plate 1 can be appropriately adjusted in slope according to the terrain conditions, ensuring the uniform distribution of water flow. At the same time, the uniform arrangement of the transverse drainage grooves 2 makes the water evenly distributed in the entire channel range, preventing the water flow from being too fast or too slow locally, thereby reducing the possibility of channel siltation or erosion and improving irrigation efficiency and farmland management level.

[0033] With reference to Figure 1 In one embodiment, the material of the channel bottom plate 1 of the high-standard farmland irrigation channel structure of the present application is high-strength concrete, which has good durability and carrying capacity and can effectively resist the influence of external environment and the impact of internal water flow. The material properties of the channel bottom plate 1 enable it to maintain stable performance during long-term use. In addition, in order to enhance the safety and stability of the channel, anti-skid lines 5 are added on both sides of the channel bottom plate 1. The design of these anti-skid lines 5 increases the friction between the bottom plate and the soil, effectively reducing the risk of water and soil loss. This design not only improves the stability and reliability of the entire channel system, but also prolongs the service life of the channel to some extent.

[0034] For example, in the process of making the channel bottom plate 1, while pouring high-strength concrete, specific molds or tools can be used to press regular anti-skid lines 5 on both sides of the bottom plate. These anti-skid lines 5 can be arranged in a cross, parallel or other manner to ensure that the soil is not easily washed away under the impact of water flow. The specific shape and spacing of the anti-skid lines 5 can be adjusted according to the water flow and soil type in actual application to achieve the best anti-skid effect. In this way, the high-standard farmland irrigation channel structure not only ensures the smooth flow of water, but also significantly reduces the risk of water and soil loss.

[0035] In one embodiment, the channel structure of the high-standard farmland irrigation channel of the present application is provided with a flow guide groove 13 on the side walls of the channel bottom plate 1, with the opening of the flow guide groove 13 facing the farmland, used to guide the excess water flow back to the farmland during irrigation, thereby achieving full utilization of water resources and reducing waste. The two side walls of the channel bottom plate 1 serve as a support structure, ensuring that the flow guide groove 13 can remain stable under the impact of water flow. The cross-sectional shape of the flow guide groove 13 can be designed as a rectangle or a semicircle to adapt to different irrigation needs and flow rates.

[0036] Specifically, the flow guide groove 13 can be formed integrally with the side walls on both sides of the channel bottom plate 1, ensuring a stable connection with the side walls. In order to ensure the smoothness and durability of the flow guide groove 13, the inner wall can be coated with a waterproof and corrosion-resistant material, such as a polyurethane coating or an epoxy resin coating. The opening part of the flow guide groove 13 can be designed with a slight inclination angle to better guide the excess water to the farmland. In addition, several flow guide baffles can be arranged inside the flow guide groove 13 to control the speed and direction of the water flow, preventing the water flow from washing away the soil of the farmland too quickly. For example, in actual application, a vertical baffle can be installed every certain distance inside the flow guide groove 13, and the height and spacing of the baffles can be adjusted to optimize water flow distribution and further improve irrigation effect.

[0037] In one embodiment, the channel structure of the high-standard farmland irrigation channel of the present application is characterized in that the cross-sectional shape of the transverse drainage groove 2 is V-shaped, with a depth of 30mm to 50mm. This design can effectively disperse the water flow and reduce the impact force of the water flow on the bottom of the channel, thereby preventing local erosion of the channel bottom. Specifically, the V-shaped cross-section of the transverse drainage groove 2 guides the water flow to both sides through its two inclined surfaces, so that the water flow is effectively dispersed before it contacts the channel bottom, reducing the direct impact force. In addition, the V-shaped design can also ensure smooth flow of water to the next area, avoiding water accumulation or sediment deposition.

[0038] For example, when making the channel, V-shaped grooves can be first opened on the channel bottom at predetermined positions and intervals, and then the overall pouring of the channel is carried out. In order to ensure the accuracy and stability of the V-shaped grooves, a mold positioning method can be used, in which a specially designed V-shaped mold is positioned and fixed at the predetermined position before pouring the concrete, and the mold is kept from moving during pouring. Specifically, the angles of the two inclined surfaces of the V-shaped groove can be set between 30° and 45° to further optimize the dispersion effect of the water flow.

[0039] In one embodiment, the lateral drainage groove 2 of the channel structure for high-standard farmland irrigation of the present application is provided with reinforcing ribs 6 at both side edges of the lateral drainage groove 2, which are perpendicular to the channel bottom plate 1 to enhance the structural strength of the lateral drainage groove 2 and prevent deformation after being subjected to water flow for a long time. Specifically, the reinforcing ribs 6 are fixedly installed at the edges of the lateral drainage groove 2 and are perpendicular to the channel bottom plate 1, forming a stable support structure. In addition, filter screens 7 are provided between the reinforcing ribs 6 to block larger debris from entering the lateral drainage groove 2 and prevent the debris from clogging and affecting the smooth flow of water. The filter screens 7 are fixed between two adjacent reinforcing ribs 6 to ensure smooth water flow while filtering out larger solid impurities. More specifically, the filter screens 7 are arranged on the surface of the lateral drainage groove 2, so that smaller particles of silt can leak into the lateral drainage groove 2 and be washed away by the water flow, while larger impurities such as stones are filtered by the filter screens and do not settle in the lateral drainage groove 2, thereby not blocking the water flow to carry away fine silt and reducing sedimentation.

[0040] Specifically, the reinforcing ribs 6 can be installed at the edges of the lateral drainage groove 2 by welding or mechanical fixation to ensure their perpendicular relationship with the channel bottom plate 1. Specifically, mounting holes or fixing seats can be pre-provided at the edges of the lateral drainage groove 2, and the reinforcing ribs 6 are firmly connected by bolts 12 or welding points. The filter screens 7 can be embedded between two adjacent reinforcing ribs 6 by a frame structure, and the four corners of the frame can be fixedly connected to the inner side surfaces of the reinforcing ribs 6 by bolts 12 to ensure the stability and filtering effect of the filter screens 7. For example, the filter screens 7 and the frame can be made of stainless steel or corrosion-resistant plastic materials to adapt to various irrigation environments.

[0041] In one embodiment, the adjustment pad 3 of the channel structure for high-standard farmland irrigation of the present application is made of an elastic material. The elastic material allows the adjustment pad 3 to maintain a certain elasticity under different terrain conditions, thereby effectively relieving the impact caused by local elevation changes. Specifically, the adjustment pad 3 is installed between the base layer of the channel and the irrigation pipeline, serving as an adjustment and support. The shape and size of the adjustment pad 3 are customized according to actual needs, and are usually cuboid or trapezoidal structures with smooth surfaces to reduce friction and wear.

[0042] In one embodiment, the adjustment pad 3 can be made of a variety of elastic materials, such as rubber or silicone. These materials not only have good elasticity and toughness, but also maintain stable performance under long-term hydraulic and mechanical action. In order to further enhance the applicability and reliability of the adjustment pad 3, its support capacity can be increased by embedding metal springs or fiber-reinforced materials inside the adjustment pad 3. For example, embedding a metal spring inside the adjustment pad 3 can further improve its stability and adaptability in uneven terrain. In addition, the upper surface of the adjustment pad 3 fits tightly with the bottom of the irrigation pipe, ensuring that the contact surface between the two is evenly stressed, reducing the impact caused by elevation changes. Specifically, the adjustment pad 3 is fixed to the channel base layer by a preset slot or adhesive to ensure its stability and reliability.

[0043] In one embodiment, Figure 2 As shown, a channel structure for high-standard farmland irrigation of the present application is characterized in that an adjustable spiral rod 8 is provided on the adjustment pad 3. By rotating the spiral rod 8, the height of the adjustment pad 3 can be accurately adjusted to ensure that the slope of the channel bottom plate 1 is uniform. Specifically, the adjustment pad 3 is installed at a key position below the channel bottom plate 1 to support the channel bottom plate 1 and adjust its height. The spiral rod 8 is installed on the top of the adjustment pad 3, passes through the adjustment pad 3 and is threadedly connected to it. In this way, when the spiral rod 8 is rotated, the height change of the adjustment pad 3 can be accurately controlled by the lifting action of its thread.

[0044] Furthermore, if Figure 3 As shown, a level ruler 9 is provided at the bottom of the screw rod 8 for measuring the levelness during installation. The level ruler 9 is fastened to the bottom of the screw rod 8 and forms an integral structure with the screw rod 8. During the installation process, the operator can read the levelness value through the scale or indicator on the level ruler 9 to ensure that the height adjustment of the adjustment block 3 is accurate. For example, when it is necessary to adjust the height of a specific part of the channel floor 1, the operator can raise or lower it by rotating the screw rod 8 while observing the reading on the level ruler 9 until the ideal levelness is reached. In this way, even on uneven ground, the slope of the entire channel floor 1 can be ensured to be uniform by adjusting the pad 3 and the screw rod 8.

[0045] In one embodiment, returning reference Figure 2The lower part of the support column 4 of the channel structure for high-standard farmland irrigation of the present application is provided with a telescopic foot 10 to adapt to different ground conditions and enhance the stability of the overall structure. The design of the telescopic foot 10 can flexibly adjust the height of the support column 4, enabling it to maintain balance on uneven ground and ensure the stability of the irrigation channel. In addition, the telescopic foot 10 is also wrapped with a layer of anti-rust layer 11, which can effectively prevent rusting problems caused by long-term exposure to outdoor environments, thereby prolonging the service life of the support column 4 and the overall structure. Through this design, not only the reliability of the irrigation system can be improved, but also the maintenance cost can be reduced.

[0046] The telescopic foot 10 is usually composed of multiple nested metal pipes, which can be connected and locked through mechanisms such as screws, pins or springs to achieve different heights. The anti-rust layer 11 can be made by electroplating, spraying or other surface treatment processes, covering the outer surface of the telescopic foot 10. This not only improves the aesthetics, but also effectively protects the foot from external corrosion. Specifically, when the height needs to be adjusted, the operator can extend or shorten the foot to the appropriate position through the adjusting device and fix it through the locking device, thereby ensuring the stability and safety of the entire irrigation channel structure.

[0047] In one embodiment, the support column 4 of the channel structure for high-standard farmland irrigation of the present application is connected with the adjusting pad 3 by a bolt 12, and the bolt 12 adopts a self-locking design. Through this design, the loosening of the bolt 12 caused by vibration or environmental factors during long-term use can be effectively prevented, ensuring the firm and reliable connection between the support column 4 and the adjusting pad 3. The support column 4 is located on both sides of the irrigation channel and mainly serves to support the entire channel structure, maintaining its stability and compression resistance. The adjusting pad 3 is arranged below the support column 4 and plays a role in adjusting and supporting, enabling the support column 4 to flexibly adjust the height and level according to the terrain and construction requirements.

[0048] In one embodiment, in order to realize the self-locking bolt 12 connection between the support column 4 and the adjusting pad 3, special bolts 12 with locking function can be selected. These bolts 12 usually have a self-locking mechanism, such as spring locking piece, nylon insert or other locking structure, which can prevent self-loosening after tightening. For example, using a self-locking bolt 12 with a nylon insert, when the bolt 12 is screwed into the threaded hole on the support column 4 and the adjusting pad 3, the nylon insert will form an internal friction, thereby providing additional tightening effect. In addition, the method of combining a lock washer with a common bolt 12 can also be used to ensure that the bolt 12 remains stable during long-term use.

[0049] In actual operation, when the device is used, first, the channel bottom plate 1 is laid on the farmland to form the bottom of the channel. The channel bottom plate 1 is provided with a plurality of transverse drainage grooves 2, which are distributed at equal intervals along the width direction of the channel bottom plate 1. The main function of the transverse drainage grooves 2 is to uniformly disperse water when the water flows through, so as to prevent the local water flow from being too fast or too slow due to uneven water distribution, thereby affecting the irrigation effect. At the same time, the adjusting pads 3 are arranged under the channel bottom plate 1 according to the height of different terrains. By adjusting the height difference of the adjusting pads 3, it is ensured that the channel bottom plate 1 can adapt to the slope requirements of different terrains, so that the water flow maintains a uniform speed in the entire channel. The adjusting pads 3 not only play a role in adjusting the slope, but also serve as the foundation of the supporting columns 4. The supporting columns 4 are fixed on the adjusting pads 3 and the side walls on both sides of the channel, and are used to support and fix the channel bottom plate 1, so as to ensure the stability and durability of the channel structure. The supporting columns 4 are connected with the adjusting pads 3 through bolts 12. This connection method is not only simple and reliable, but also convenient for disassembly and maintenance. Overall, through the cooperation between the channel bottom plate 1, the transverse drainage grooves 2, the adjusting pads 3 and the supporting columns 4, the irrigation channel structure can realize efficient and uniform farmland irrigation under various complex terrains, improve the utilization efficiency of water resources, and reduce the labor intensity of farmers.

[0050] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
