Description

Technical Field

[0001] This utility model relates to the field of water pollution control equipment technology, specifically to an ecological interception ditch for the prevention and control of non-point source pollution in farmland. Background Technology

[0002] With the acceleration of agricultural modernization, non-point source pollution from farmland has become increasingly prominent, posing a significant threat to water quality and ecological balance. Pollutants such as fertilizers, pesticides, and livestock manure from farmland are carried into water bodies by surface runoff from rainfall or irrigation, leading to eutrophication of rivers, lakes, and other bodies of water. This threatens the habitat of aquatic organisms and poses a potential risk to the safety of human drinking water.

[0003] Chinese utility model patent CN221567039U proposes an ecological interception ditch for the prevention and control of non-point source pollution in farmland, which relates to the field of water pollution control technology. It includes a ditch body and multiple flow-blocking structures equidistantly distributed within the ditch body. The ditch body includes two symmetrically arranged ditch walls. By setting the flow-blocking structures, the water flow residence time is increased, the filtration performance of nitrogen and phosphorus in the water is improved, and thus the purification effect of the ecological ditch is enhanced.

[0004] The aforementioned device features an integrated design for the interception ditch walls, resulting in a relatively long overall length. This not only increases the difficulty and cost of material transportation but also makes on-site installation work complex and arduous. Especially in farmland areas with complex terrain, the long ditch walls are easily damaged during transportation and are not easily adjustable to adapt to different terrains, limiting their versatility and effectiveness in practical applications. Therefore, we propose an ecological interception ditch for the prevention and control of non-point source pollution in farmland to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An ecological interception ditch for the prevention and control of non-point source pollution in farmland includes:

[0007] Flow-retarding seats are evenly spaced inside the ditch, and limit plates are provided on both sides of the flow-retarding seats;

[0008] A flow guide plate is disposed on both sides of the top of the flow-slowing seat near the limiting plate. Connecting plates are fixed on both sides of the flow guide plate. The connecting plates on both sides are staggered and each has a connecting hole.

[0009] The flow control assembly includes a stud that slides through the connection hole, a mounting plate fixed to the top of the stud, and a baffle fixed to one side of the bottom of the mounting plate.

[0010] Furthermore, the top of the flow-slowing seat is arc-shaped, and the bottom side of the guide plate has an arc-shaped notch that matches the flow-slowing seat.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This application provides an ecological interception ditch for the prevention and control of non-point source pollution in farmland. It primarily addresses the problem that the ditch walls are designed as a single unit with a long overall length. This not only increases the difficulty and cost of material transportation but also makes on-site installation complex and arduous, especially in farmland areas with complex terrain. Long ditch walls are easily damaged during transportation and are not easily adjustable to adapt to different terrains, limiting their versatility and effectiveness in practical applications. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0024] An ecological interception ditch for the prevention and control of non-point source pollution in farmland includes:

[0025] Slow-flow seat 1 is set at equal intervals inside the ditch, and limit plates 2 are set on both sides of slow-flow seat 1;

[0026] The guide plate 3 is set on both sides of the top of the flow-slowing seat 1 near the limiting plate 2. The two sides of the guide plate 3 are fixed with connecting plates 4. The two connecting plates 4 are staggered and each has a connecting hole 401.

[0027] The flow control component 5 includes a stud 501 that slides through the connection hole 401, a mounting plate 502 fixedly mounted on the top of the stud 501, and a baffle 503 fixedly mounted on one side of the bottom of the mounting plate 502.

[0028] Workflow Description:

[0029] Preparation stage: Based on the actual situation of non-point source pollution in farmland and the terrain characteristics, select an appropriate number of guide plates 3, flow-slowing seats 1 and flow-slowing components 5;

[0030] Excavating ditches: According to the design requirements, dig ditches of appropriate depth and width in the farmland as the basis for ecological interception ditches.

[0031] To install and deploy, place the flow-retarding seats 1 at equal intervals inside the ditch, ensuring they are stable and level. Place the guide plates 3 on both sides of the top of each flow-retarding seat 1 near the limiting plate 2. Then, align the connecting holes 401 of the adjacent connecting plates 4. Finally, insert the stakes 501 into the connecting holes 401, embedding their bottom ends into the soil. This completes the installation.

[0032] The ecological interception ditch used for the prevention and control of non-point source pollution in farmland adopts a modular design, consisting of detachable components such as a flow-slowing seat 1, a flow guide plate 3, a stake 501, and a baffle 503, which facilitates transportation and on-site assembly. This design reduces the difficulty and cost of material transportation and improves the efficiency of on-site installation.

[0033] like Figure 1As shown, in some embodiments, the top of the flow-slowing seat 1 is arc-shaped, and the bottom center of the guide plate 3 has an arc-shaped notch 302 adapted to the flow-slowing seat 1. More specifically, the arc-shaped top design can more evenly disperse the force of the water flow when subjected to water flow impact. Compared with flat or sharp top designs, the arc-shaped structure can gradually disperse the impact force of the water flow along the arc surface, reducing the risk of structural damage caused by excessive local stress. This ensures that the flow-slowing seat 1 can maintain good structural integrity even when subjected to water flow impact of different degrees during long-term use. The cooperation between the arc-shaped notch 302 and the flow-slowing seat 1 forms a complementary structural relationship, enhancing the connection strength between the guide plate 3 and the flow-slowing seat 1. This tight fit makes the guide plate 3 more stable after installation, reducing the possibility of the guide plate 3 loosening or shifting due to water flow impact or other external forces.

[0034] like Figure 3 As shown, in some embodiments, the surface of the guide plate 3 is uniformly distributed with drainage holes 301. More specifically, in the early stages of rainfall or during farmland irrigation, a large amount of surface runoff flows into the interception ditch. Without these drainage holes 301, the water level in the ditch would rise rapidly, which may cause the river water to overflow the ditch and fail to effectively intercept pollution. The drainage holes 301 can allow some water to flow out through the holes when the water level is too high, maintaining the water level in the ditch within a reasonable range and avoiding the reduction of the water flow's residence time in the ditch due to the high water level, which would affect the sedimentation and treatment effect of pollutants.

[0035] like Figure 1 As shown, in some embodiments, two adjacent baffles 503 are staggered, or more specifically, two adjacent baffles 503 are staggered, so that the water flow cannot pass through the interception ditch in a straight line, but needs to change direction constantly. This tortuous flow path significantly prolongs the time the water stays in the ditch, just like the water flow is shuttling through a maze. Every turn and obstacle makes it stay for a while longer. During rainfall, the surface runoff may have passed through a straight channel quickly, but now, due to the staggered baffles 503, it needs to meander between each baffle 503, thus having more time to settle the suspended matter such as silt and humus.

[0036] like Figure 2 As shown, in some embodiments, the bottom end of the stake 501 is conical, and the thickness of the baffle 503 gradually decreases from one side near the mounting plate 502 to the other. More specifically, the conical bottom end can easily penetrate the soft sand layer and reach into the relatively stable stratum, providing a solid foundation for the entire ecological interception ditch device. Compared to the flat-bottomed or blunt-bottomed stake 501, the conical bottom end acts like a wedge, allowing it to enter the soil more smoothly. The gradually decreasing thickness of the baffle 503 makes it easier for its bottom end to be inserted into the soil, thereby forming a stable structure.

[0037] like Figure 2 As shown, in some embodiments, a pull rod 504 is fixed to the top of the mounting plate 502, and the surface of the pull rod 504 is provided with an anti-slip sleeve. More specifically, the design of the pull rod 504 makes it easier for workers to pull the stake 501 out of the soil.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
