Description

Technical Field

[0001] This utility model relates to the field of runoff interception technology on sloping farmland, and more specifically, to an ecological diversion channel structure for runoff interception on sloping farmland. Background Technology

[0002] Sloping farmland, as an important type of agricultural land, is widely distributed in my country and even worldwide. However, due to the slope of the terrain, sloping farmland is highly susceptible to runoff during rainfall or irrigation. This runoff not only carries large amounts of soil and fertilizer, causing serious soil erosion and decreased soil fertility, but may also trigger a series of ecological and environmental problems downstream, such as floods and water pollution. Therefore, the effective interception and treatment of runoff from sloping farmland is of paramount importance.

[0003] Currently, some devices and technologies exist on the market for intercepting runoff on sloping farmland. However, these existing technologies generally have many defects and shortcomings, specifically: Traditional runoff interception devices are simply designed, and the size and shape of their runoff collection inlets are unreasonable, making it impossible to effectively collect scattered runoff on sloping farmland. In cases of heavy rainfall or uneven runoff distribution on the slope, a large amount of runoff will bypass the interception device and flow directly away, resulting in low interception efficiency and failing to achieve the expected runoff control effect.

[0004] Existing diversion channels lack effective diversion structures, and when runoff enters the channels, it often flows in a concentrated, large stream. Many traditional runoff interception devices do not consider the protection of slope soil and lack effective soil stabilization measures. Under long-term erosion by runoff, slope soil is easily lost, leading to slope instability and potentially triggering geological disasters such as landslides. Furthermore, soil erosion also removes large amounts of nutrients, reducing the fertility of sloping farmland and affecting crop growth.

[0005] Although the existing facilities include slope protection structures, their design is inadequate and fails to effectively buffer the direct erosion of the slope by runoff. The selection of slope protection materials is also problematic; their durability and erosion resistance are poor, making them prone to damage within a short period and rendering them ineffective in protecting the slope.

[0006] Existing drainage channels often employ only one drainage method and lack flexible drainage design. When runoff is high, the channels cannot discharge excess water in time, easily leading to overflow and damaging the surrounding environment. Furthermore, the size and location of some drainage outlets are fixed and cannot be adjusted according to actual conditions, failing to adapt to varying rainfall intensities or irrigation needs.

[0007] Traditional runoff interception devices mostly lack flow regulation capabilities, making it impossible to precisely control runoff flow based on the actual needs of sloping farmland and the carrying capacity of downstream drainage systems. This can lead to excessive water accumulation on sloping farmland in some cases, affecting crop growth, while in other cases, it can result in water waste.

[0008] Most existing flow channels tend to accumulate silt, debris, and other dirt over long-term use, affecting their flow guiding effect. However, these devices generally lack effective self-cleaning systems, requiring regular manual cleaning, which is not only labor-intensive and inefficient but also difficult to guarantee in terms of cleaning effectiveness. Over time, the accumulation of dirt becomes increasingly severe, eventually leading to blockage of the flow channel and loss of its intended function.

[0009] The existing equipment has an inadequate structural design and lacks necessary reinforcement measures, resulting in poor stability on sloping farmland. When subjected to runoff erosion, external impacts, or natural factors, it is prone to displacement and tipping, affecting its normal use. Furthermore, the unstable structure increases the risk of damage and shortens its service life.

[0010] In summary, existing runoff interception technologies for sloping farmland have many shortcomings and deficiencies, failing to meet the needs of practical applications. Therefore, developing an efficient, environmentally friendly, stable, and easy-to-install and maintain ecological diversion channel structure is of significant practical importance. Consequently, we propose an improved ecological diversion channel structure for runoff interception on sloping farmland. Utility Model Content

[0011] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned utility model objective, this utility model provides the following technical solution: an ecological diversion channel structure for intercepting runoff on sloping farmland, including a diversion channel hole, a diversion inner plate is provided inside the diversion channel hole, and the diversion channel hole is connected to the flow channel shell.

[0012] As a preferred technical solution of this utility model, a soil-stabilizing grid is provided on the outside of the flow channel shell, and the side of the soil-stabilizing grid is provided with reinforcing ribs.

[0013] As a preferred technical solution of this utility model, the end of the flow channel shell is provided with a flow diversion connection flange, and the flow diversion connection flange is provided with a drain hole.

[0014] As a preferred technical solution of this utility model, the diversion connection flange is provided with a slope protection gasket in annular shape.

[0015] As a preferred technical solution of this utility model, the outer surface of the flow channel shell is provided with an annular groove.

[0016] As a preferred technical solution of this utility model, a flow channel is provided inside the flow channel housing, and a flow channel flushing nozzle is provided inside the flow channel.

[0017] As a preferred technical solution of this utility model, the flow channel flushing nozzle is provided with a nozzle head, the nozzle head is provided with a nozzle outlet hole, the flow channel flushing nozzle is connected to the flushing nozzle delivery pipe, and the flushing nozzle delivery pipe is also provided in the flow channel of the guide groove.

[0018] As a preferred technical solution of this utility model, the end of the flushing nozzle infusion pipe is provided with a flushing pipe infusion connection flange, and a flushing inlet hole is provided inside the flushing pipe infusion connection flange.

[0019] Compared with existing technologies, the beneficial effects of this invention are as follows: the guide channel holes, as the main inlet for runoff, can effectively collect scattered runoff on sloping farmland through their reasonable design. Compared with traditional runoff collection methods, it can gather water flow over a larger area, preventing runoff from flowing randomly on the slope, improving the interception efficiency of runoff on sloping farmland, and reducing soil erosion and water waste caused by runoff loss.

[0020] The inner diversion plate is installed inside the guide channel holes. When runoff enters, it evenly disperses it into multiple smaller streams. This diversion effect allows the water to enter the flow channel shell more smoothly, avoiding the strong impact of a concentrated large stream of water on the guide channel, reducing the risk of damage to the guide channel due to excessive local stress, and extending the service life of the guide channel. At the same time, the uniform water flow distribution also helps to smoothly guide and treat subsequent runoff.

[0021] The soil-stabilizing grid and reinforcing ribs outside the flow channel shell work together to form a stable soil-stabilizing structure. The soil-stabilizing grid increases the contact area and friction with the surrounding soil, effectively fixing the slope soil and preventing soil loss under runoff erosion. The reinforcing ribs further enhance the structural strength of the soil-stabilizing grid, enabling it to withstand greater external forces. In this way, soil erosion on sloping farmland is reduced, soil fertility is protected, and the sustainable use of sloping farmland is promoted.

[0022] The slope protection liner, with its ring-shaped flange for diversion connections, provides additional protection for the slope. It buffers the direct scouring of the slope by runoff, reduces erosion of the slope surface, and maintains slope stability. Furthermore, the slope protection liner also acts as a filter, intercepting some of the sediment and debris in the runoff, reducing pollution to the downstream environment and promoting the healthy development of the ecological environment surrounding sloping farmland.

[0023] The drain holes on the diversion flange can discharge a portion of the runoff as needed, depending on the water volume in the diversion channel. When the runoff volume is large, the drain holes can divert some of the water flow, reducing the drainage pressure on the diversion channel and preventing overflow due to excessive water volume. This flexible drainage design allows the diversion channel to adapt to rainfall or irrigation conditions of varying intensities, ensuring its normal operation under various conditions.

[0024] The flow channel flushing nozzle, the flushing nozzle inlet pipe, the flushing pipe inlet flange, and the flushing inlet hole together constitute the flow channel's self-cleaning system. When sediment or other debris accumulates in the flow channel, water can be sprayed from the round outlet of the nozzle head through an external water source, thoroughly flushing the inner wall of the flow channel. This self-cleaning function can promptly remove dirt from the flow channel, ensuring its unobstructed flow and preventing problems such as poor flow and reduced drainage efficiency caused by debris blockage.

[0025] The annular grooves on the outer surface of the channel shell increase friction with the surrounding soil, making the diversion channel more stable on sloping farmland. Even when subjected to runoff scouring, external impacts, or natural factors, it maintains a relatively fixed position and is not prone to displacement or tipping. This stable structure ensures that the diversion channel can continuously and reliably perform its functions of runoff interception and diversion. Attached Figure Description

[0032] 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. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0033] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] Example 1: An ecological diversion channel structure for intercepting runoff on sloping farmland includes a diversion channel hole 1, a diversion inner plate 2 inside the diversion channel hole 1, and the diversion channel hole 1 connected to a channel shell 3. A soil stabilizing grid 4 is installed outside the channel shell 3, and reinforcing ribs 5 are provided on the sides of the soil stabilizing grid 4. A diversion connecting flange 6 is provided at the end of the channel shell 3, and a drainage hole 7 is provided on the diversion connecting flange 6. A slope protection pad 8 is provided annularly on the diversion connecting flange 6. An annular groove 9 is provided on the outer surface of the channel shell 3. A diversion channel 10 is provided inside the channel shell 3, and a channel flushing nozzle 11 is provided inside the diversion channel 10. The channel flushing nozzle 11 is provided with a nozzle head 12, and a nozzle head liquid outlet 13 is provided on the nozzle head 12. The channel flushing nozzle 11 is connected to a flushing nozzle delivery pipe 14, which is also located inside the diversion channel 10.

[0035] The end of the flushing nozzle inlet pipe 14 is equipped with a flushing pipe inlet connection flange 15, and a flushing inlet hole 16 is provided inside the flushing pipe inlet connection flange 15. When runoff is generated on the sloping farmland due to rainfall or irrigation, the runoff first flows into the guide channel hole 1. Since the guide channel hole 1 is equipped with a diversion inner plate 2, the runoff is divided into multiple smaller water streams after entering the guide channel hole 1. This initial diversion effect allows the runoff to enter the flow channel shell 3 connected to the guide channel hole 1 more evenly, avoiding excessive impact on subsequent structures caused by concentrated large water streams.

[0036] The runoff entering the flow channel housing 3 flows along the guide channel 10. The diversion flange 6 at the end of the flow channel housing 3 serves to connect multiple guide channel structures and control runoff discharge. Part of the runoff is discharged through the drain hole 7 on the diversion flange 6 to regulate the water volume in the guide channel and prevent excessive accumulation of runoff in the guide channel.

[0037] The soil-stabilizing grid 4 and its side reinforcing ribs 5, installed outside the flow channel shell 3, work together to reinforce the surrounding soil. The soil-stabilizing grid 4 increases the contact area and friction with the soil, while the reinforcing ribs 5 further enhance the structural strength of the soil-stabilizing grid 4, thus effectively preventing soil loss from sloping farmland due to runoff erosion. At the same time, the slope protection gasket 8, which is annularly arranged on the diversion connecting flange 6, can reduce the direct erosion of the slope by runoff and protect the stability of the slope.

[0038] During long-term use, sediment and other debris will gradually accumulate in the flow channel 10 of the guide channel, affecting the normal flow of runoff. At this time, the flow channel 10 can be flushed using the flow channel flushing nozzle 11. External water enters the flushing nozzle delivery pipe 14 through the flushing inlet hole 16 on the flushing pipe connection flange 15, and is then delivered to the flow channel flushing nozzle 11. Water is sprayed out from the round outlet hole 13 on the nozzle head 12, flushing the inner wall of the flow channel 10, removing the accumulated sediment and other debris, and ensuring the smooth flow of the flow channel 10.

[0039] The various components of the ecological diversion channel structure work together to intercept, divert, and treat runoff from sloping farmland. The annular groove 9, located on the outer surface of the channel shell 3, increases the friction between the shell 3 and the surrounding soil, further enhancing the stability of the entire diversion channel structure. Through their rational placement and connection, the components form an organic whole, efficiently addressing runoff issues on sloping farmland and achieving eco-friendly runoff interception and treatment.

[0040] When rainfall or irrigation occurs on sloping farmland, the water naturally flows towards lower elevations and converges at the diversion channel opening 1. Diversion channel opening 1, as the inlet of the entire ecological diversion channel structure, effectively collects runoff from the sloping farmland.

[0041] After the runoff enters the guide channel hole 1, the inner diversion plate 2, located inside the guide channel hole 1, disperses the originally concentrated runoff into multiple smaller streams. This process allows the runoff to enter the subsequent flow channel shell 3 more evenly, avoiding impact and damage to the guide channel caused by excessive local water flow, and ensuring the stability and durability of the entire structure.

[0042] After initial diversion, the runoff enters the flow channel housing 3 and flows within the guide channel 10. The diversion connecting flange 6 at the end of the flow channel housing 3 plays a crucial role in connecting different guide channel structures and regulating runoff discharge. Part of the runoff is discharged through the evenly distributed drainage holes 7 on the diversion connecting flange 6, thereby regulating the water volume in the guide channel, preventing excessive accumulation of runoff in the guide channel, and avoiding problems such as overflow caused by excessive water volume.

[0043] During runoff diversion, the soil-stabilizing grid 4 on the outside of the channel shell 3 plays a crucial role in soil stabilization. The soil-stabilizing grid 4 increases the contact area and friction with the surrounding soil, effectively fixing the soil and preventing it from being washed away by runoff. Simultaneously, the reinforcing ribs 5 on the sides of the soil-stabilizing grid 4 further enhance its structural strength and improve its soil-stabilizing effect. In addition, the annularly arranged slope protection gasket 8 on the diversion connecting flange 6 reduces the direct scouring of the slope by runoff, protecting the slope's stability and maintaining the ecological balance of the sloping farmland.

[0044] With prolonged use, sediment and debris will gradually accumulate inside the flow channel 10 of the guide channel. To ensure the normal flow guidance function of the guide channel, the flow channel 10 needs to be flushed periodically. At this time, an external water source is connected to the flushing nozzle delivery pipe 14 via the flushing pipe delivery flange 15. The water source enters the flushing nozzle delivery pipe 14 through the flushing inlet hole 16 and is delivered to the flow channel flushing nozzle 11. Water is sprayed out at a certain pressure from the round outlet hole 13 on the nozzle head 12, thoroughly flushing the inner wall of the guide channel 10, removing accumulated sediment and debris, and ensuring the unobstructed flow of the guide channel 10.

[0045] The annular groove 9 on the outer surface of the flow channel shell 3 increases the friction between the flow channel shell 3 and the surrounding soil, further improving the stability of the entire diversion channel structure on sloping farmland. Even under long-term runoff scouring and external forces, the position of the diversion channel structure can be kept relatively fixed, ensuring that it can continuously and effectively play its role in runoff interception and diversion.

[0046] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
