[0002] Artificial waterways are built for farmland. The main function of existing ditches is to divert water for irrigation. The traditional slope lining of ditches is mostly three-sided smooth lining. The above three-sided smooth lining method allows the irrigation water to flow smoothly, but the fertilizers and pesticides in the farmland enter the natural streams and rivers and lakes with the irrigation and drainage of the ditches, causing water pollution, damage to the aquatic ecosystem, and even affecting drinking water safety.
[0003] Planting aquatic plants in ditches on pristine land without lining structures is a trend in ecological ditches. However, as irrigation water flushes, the soil in the ditch is lost due to the erosion of irrigation water. In addition, the irrigation water mixes with and accumulates sand and soil, destroying the soil structure of the pristine land. This in turn causes aquatic plants to be unable to grow normally, and the functionality and ecology of the ecological ditch cannot be guaranteed.
[0004] In summary, the existing farmland ecological ditches have the technical problem that the irrigation water is mixed with and silted up with sand, which destroys the soil structure of the original land and thus causes aquatic plants to be unable to grow normally. Utility Model Content

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the examples of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
[0026] Specific implementation method 1: Combination Figure 1 Describe this embodiment. This embodiment is a soil and water conservation ecological ditch, which includes a ditch body 1, a drainage plate 2, a sand outlet 3, a sand pool 4 and a retaining plate 5. An inverted trapezoidal channel 6 is provided in the middle of the ditch body 1, and a sand outlet 3 is opened on one side of the inverted trapezoidal channel 6. A drainage plate 2 is arranged on the inner side of the sand outlet 3. Several drainage plates 2 are arranged obliquely along the inverted trapezoidal channel 6, and the tail of the drainage plate 2 points to the sand outlet 3. A sand pool 4 is provided on the outside of the sand outlet 3. The sand pool 4 is built with concrete mortar material, and the bottom elevation of the sand pool is lower than the bottom elevation of the inverted trapezoidal channel 6. The inverted trapezoidal channel 6 is connected with the sand pool 4 through the sand outlet 3, and a retaining plate 5 is detachably installed between the sand outlet 3 and the sand pool 4. On the one hand, the function of the drainage plate 2 is to guide the irrigation water to the sand and soil mouth. When the retaining plate 5 is removed, the irrigation water flows into the sand and soil pool. On the other hand, the drainage plate 2 can play a turbulent role to a certain extent, reducing the flow rate of the irrigation water, reducing the scouring of the inverted trapezoidal channel structure, and retaining the sand in the irrigation water in the sand and soil pool. Turbulence blocks are provided in the sand and soil pool to prevent the irrigation water from flowing back to the inverted trapezoidal channel at too fast a speed, thereby preventing the irrigation water from carrying away too much sand and soil, reducing the content of mixed and deposited sand and soil in the irrigation water, protecting the soil structure of the original land, and allowing aquatic plants to grow normally.
[0027] Specific implementation method 2: Combination Figure 1 and Figure 2This embodiment differs from the first embodiment in that the inverted trapezoidal channel 6 of the ditch body 1 includes a ditch soil layer 61, a gravel layer 62, and a brick layer 63. The bottom and sides of the inverted trapezoidal channel 6 of the ditch body 1 are paved with a gravel layer 62. The lower layer of the gravel layer 62 is the original soil layer 61, and the upper layer of the gravel layer 62 is paved with a brick layer 63, which is made of hollow bricks. The gravel layer maintains water permeability in the ditch and preserves the ecology of the original soil. The purpose of the hollow brick layer is to allow aquatic plants to grow through the holes in the hollow bricks, thereby better maintaining the ecological environment in the irrigation water. The other components and connection methods are the same as those in the first embodiment.
[0028] Specific implementation method three: Combination Figure 1 and Figure 2 This embodiment differs from the first embodiment in that aquatic plants 7 are planted in the original soil layer 61 below the gravel layer 62. These plants are one or more of the following: aquatic canna, pennywort, black schizonepeta, myriophyllum spicatum, and rush. Their purpose is to absorb pollutants such as nitrogen and phosphorus from the irrigation water, thereby maintaining the ecological environment. The remaining components and connection methods are the same as those in the first or second embodiments.
[0029] Specific implementation method four: Combination Figures 1 to 4 This embodiment differs from the first embodiment in that several sand buckets 8 are arranged within the sand pit 4. Water holes 9 are provided in the walls of these buckets. These buckets 8 allow for the removal of sand from the pit 4 when it is full, eliminating the need for direct desilting in the pit 4 and improving efficiency. The remaining components and connections are the same as in any of the first through third embodiments.
[0030] Specific implementation method five: Combination Figures 1 to 4 This embodiment differs from the first embodiment in that water holes 9 are shaped like a cross. This cross-shaped water hole 9 is less susceptible to clogging and improves the flow of irrigation water between the sand and soil buckets 8. The remaining components and connections are the same as those of any of the first to fourth embodiments.
[0031] Specific implementation method six: combination Figures 1 to 4 This embodiment differs from the first embodiment in that a handle 10 is installed on the top of the sand bucket 8 to facilitate lifting. The other components and connection methods are the same as any of the first to fifth embodiments.
[0032] Specific implementation method seven: combination Figures 1 to 4This embodiment differs from the first embodiment in that a thickness gauge 11 is detachably mounted on the wall of the sand pit 4. This gauge is used to measure the thickness of the accumulated sand within the sand pit 4. The thickness gauge 11 facilitates monitoring and measuring the thickness of the accumulated sand within the sand pit 4, allowing for timely removal and improving the convenience of this embodiment. The remaining components and connections are identical to any of the first through sixth embodiments.
[0033] Specific implementation method eight: combination Figures 1 to 5 This embodiment is described. The difference between this embodiment and the specific embodiment 1 is that the thickness ruler 11 includes a ruler bottom 12, a ruler body 13 and a ruler hand 14. The ruler bottom 12 is conical, the ruler body 13 is cylindrical, and a plurality of ruler hands 14 are evenly installed on one side of the ruler body 13. The function of the ruler hand 14 is that when the thickness of the silted sand reaches the height of the ruler hand, the thickness ruler 11 can be pulled out to facilitate observation by the user. The function of the conical bottom 12 is that after the thickness ruler 11 is pulled out to complete the detection of the thickness of the silted sand in the sand pool 4, if the thickness of the silted sand does not meet the cleaning standard, the thickness ruler 11 needs to be inserted back to its original position. The ruler bottom 12 is set to be conical to facilitate the operation. The other components and connection methods are the same as any one of the specific embodiments 1 to 7.
[0034] Specific implementation method nine: combination Figures 1 to 5 This embodiment differs from the first embodiment in that the plurality of fingers 14 are attached to the ruler body 13 at an oblique downward angle. This facilitates the accumulation of sediment in the angle between the fingers 14 and the ruler body 13, improving the accuracy of monitoring sediment thickness. The remaining components and connection methods are the same as those of any of the first through eighth embodiments.
[0035] Combine Figures 1 to 5 Explain the working principle of this utility model:
[0036] The diversion plate directs irrigation water to the sand and soil inlet. When the retaining plate is removed, the irrigation water flows into the sand and soil pool. Furthermore, the diversion plate creates a certain degree of turbulence, reducing the flow rate of irrigation water and reducing erosion on the inverted trapezoidal channel structure. This retains sand in the irrigation water in the sand and soil pool, preventing the irrigation water from carrying away excessive sand. This reduces the amount of sand mixed in the irrigation water and silting it, protecting the soil structure of the original land and allowing the normal growth of aquatic plants. The aquatic plants are one or more of the following: aquatic canna, pennywort, black trifoliate vine, spike-flowered foxtail algae, and rush. Their purpose is to absorb pollutants such as nitrogen and phosphorus from the irrigation water, maintaining the ecological environment within the irrigation water.
[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
