Abstract
Description
A drainage structure for protecting water and soil resources in mountainous areas Technical Field
[0001] This invention relates to the field of drainage facilities technology in mountainous areas, and in particular to a drainage structure for protecting water and soil resources in mountainous areas. Background Technology
[0002] Mountainous terrain features steep slopes and loose topsoil, making it highly susceptible to soil erosion under rainfall. Large amounts of sediment accumulate and are discharged with surface runoff, leading not only to the continuous loss of precious soil resources and decreased land productivity, but also to siltation and water quality deterioration in downstream rivers, impacting the normal operation of water conservancy projects and regional ecological security. Therefore, implementing soil and water conservation measures that "retain soil and divert clean water" has become crucial for maintaining ecological stability in mountainous areas, ensuring sustainable agricultural production, and safeguarding water resources.
[0003] However, existing drainage structures in mountainous areas mostly employ single drainage channels, lacking targeted designs for soil and water separation and sediment pretreatment. This makes it difficult to effectively intercept sediment in runoff, leading to continuous soil resource loss. While some systems are equipped with interception facilities, their interception components are often fixed structures, prone to blockage due to sediment and impurities after long-term operation, resulting in a significant decrease in interception performance. Furthermore, existing interception facilities are often directly connected to drainage channels, frequently requiring drainage interruptions for dredging and maintenance. This not only increases the difficulty of operation and maintenance but also affects the system's continuous drainage capacity, hindering the achievement of the core objective of separating soil and water resources for protection and restricting the overall effectiveness of soil and water resource protection and watershed ecological security in mountainous areas. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing drainage structures in mountainous areas, which are unable to effectively intercept sediment in water flow, leading to continuous loss of soil resources. Some structures equipped with interception functions have fixed interception components that are easily covered and blocked by sediment after long-term use, resulting in a significant reduction in interception effectiveness. At the same time, the intercepted sediment is directly connected to the drainage channel, requiring shutdown for cleaning, which not only increases the difficulty of subsequent treatment but also affects the smooth flow of drainage. Therefore, this invention proposes a drainage structure to protect water and soil resources in mountainous areas.
[0005] To achieve the above objectives, the present invention adopts the following technical solution.
[0006] A drainage structure for protecting water and soil resources in mountainous areas includes a composite drainage ditch and an automatic filtration and sewage discharge mechanism. The automatic filtration and sewage discharge mechanism is located below the water source inlet and is equipped with an impurity pretreatment mechanism. The automatic filtration and sewage discharge mechanism includes a fixed outer cavity and an inner filter ring structure. The inner filter ring structure is rotatably mounted on the fixed outer cavity via bearings and is driven by a drive assembly. The inner filter ring structure has multiple interception structures distributed along the inner ring of the inner filter ring structure. The two ends of the multiple interception structures are respectively located in two annular guide grooves. The annular guide grooves are formed on an annular mounting rail, which is fixedly connected to the fixed outer cavity.
[0007] Preferably, the composite drainage ditch includes a drainage ditch, the fixed outer cavity is fixedly installed at one end of the drainage ditch, a grid filter plate is installed in the drainage ditch, and a lower filter geotextile is provided above the grid filter plate.
[0008] Preferably, the impurity pretreatment mechanism includes an impurity collection chamber, which is installed on a drainage ditch. Multiple collection chamber fixing frames are fixedly connected to the impurity collection chamber, and the multiple collection chamber fixing frames are fixedly connected to a fixed outer cavity.
[0009] Preferably, a mesh filter structure is installed below the impurity collection chamber, and an upper filter geotextile is provided on the bottom wall of the impurity collection chamber and above the mesh filter structure.
[0010] Preferably, the impurity collection chamber is provided with a collection chamber drain port on both sides, and the collection chamber drain port is provided with a drain port side door structure.
[0011] Preferably, one end of the impurity collection chamber is placed in the fixed outer cavity to collect the impurities intercepted by the interception structure.
[0012] Preferably, the drive assembly includes a drive motor, which is mounted on an annular mounting rail. The output shaft of the drive motor is fixedly connected to a transmission gear, which meshes with a transmission gear ring, which is fixedly mounted on the outer ring of the inner filter ring structure.
[0013] Preferably, the interception structure includes multiple mounting guide sleeves, which are mounted on the inner filter ring structure. Each of the multiple mounting guide sleeves has an interception rod slidably connected to it, and one end of each of the multiple interception rods is fixedly connected to the same connecting strip.
[0014] Preferably, both ends of the connecting strip are fixedly connected to guide wheels, and the guide wheels are slidably connected in an annular guide groove.
[0015] Preferably, the annular guide groove includes an arc-shaped segment and an arc-shaped raised segment, and the arc-shaped segment and the arc-shaped raised segment are smoothly transitioned.
[0016] Compared with existing technologies, this invention has the following beneficial effects: This drainage structure for protecting water and soil resources in mountainous areas forms a debris barrier through a combination of multiple interception structures. This allows water flow to pass through and intercept debris and larger silt, achieving a pre-treatment effect. Secondly, driven by the drive component, the interception structures can rotate at a uniform speed, alternately entering the lowered interception area. When one end of the interception structure enters the arc-shaped protrusion section, the interception structure retracts, allowing debris and impurities to smoothly enter the collection component for collection. After cleaning, the interception structure resets and is put back into use, thus ensuring continuous interception. This drainage structure, designed to protect water and soil resources in mountainous areas, avoids the failure issues of traditional fixed interception structures caused by long-term stress and debris accumulation, ensuring stable interception efficiency. Through the flexible and adaptable nature of the interception structure, intercepted debris and impurities can fall smoothly into the impurity collection chamber for collection. Simultaneously, the mesh filter structure and upper filter geotextile further separate silt, debris, and water, reducing the difficulty of subsequent treatment. Furthermore, the impurity collection chamber is isolated from the composite drainage ditch, allowing workers to clean silt through the side door structure of the impurity collection chamber's discharge outlet. Therefore, this method effectively... Pre-treatment of larger debris facilitates subsequent cleaning, reduces the difficulty of subsequent filtration, and improves drainage efficiency. This drainage structure for protecting water and soil resources in mountainous areas uses a drive component to rotate the inner filter ring structure, allowing the interception structure to alternately enter the interception area. After interception, it carries away debris. When the interception structure reaches the arc-shaped protrusion, it can extend and retract, thus smoothly discharging the debris into the collection component. Its self-cleaning characteristics ensure that the intercepted debris continuously and evenly enters the collection component for individual collection. The individual collection function solves the problem of debris discharge, avoiding incomplete cleaning. The time affects the interception effect, which leads to the need to stop the operation and increases the workload and difficulty of subsequent treatment. The synergy of the two not only greatly improves the efficiency of sediment interception and recycling, but also ensures the long-term smooth flow of drainage channels, and truly achieves the goal of water and soil separation and resource protection of "retaining soil and guiding clean water". The drainage structure for protecting water and soil resources in mountainous areas adopts a double-layer composite structure of composite drainage ditches. Its overall shape is V-shaped. The upper ditch is trapezoidal, and the lower V-shaped ditch is mainly used for water drainage. The upper layer is composed of a mesh filter plate and a lower filter geotextile to form a filtration structure, realizing water filtration and soil collection. Attached Figure Description

In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0020] Example 1: Referring to Figures 1-5 and 7-11, a drainage structure for protecting water and soil resources in mountainous areas includes a composite drainage ditch 100 and an automatic filtration and sewage discharge mechanism 300. The composite drainage ditch 100 includes a drainage ditch 101, and a fixed outer cavity 301 is fixedly installed at one end of the drainage ditch 101. A mesh filter plate 102 is installed in the drainage ditch 101, and a lower filter geotextile 103 is provided above the mesh filter plate 102. The mesh filter plate 102 and the lower filter geotextile 103 can intercept fine silt, thereby achieving the effect of water and sand separation. At the same time, it can realize the collection and utilization of soil resources. The automatic filtration and sewage discharge mechanism 300 is located below the water source inlet 400, and an impurity pretreatment mechanism 200 is installed on the automatic filtration and sewage discharge mechanism 300.The automatic filtration and sewage discharge mechanism 300 includes a fixed outer cavity 301 and an inner filter ring structure 302. The inner filter ring structure 302 is rotatably mounted on the fixed outer cavity 301 via bearings. The inner filter ring structure 302 can be stably rotated by the bearings, thereby allowing the ring-shaped interception structures 306 to alternately perform interception operations. The inner filter ring structure 302 is driven by a drive assembly 305, which includes a drive motor 3051. The drive motor 3051 is mounted on a ring-shaped mounting rail 303. The output shaft of the drive motor 3051 is fixedly connected to a transmission gear 3052. 52 meshes with the transmission gear ring 3053, and power is transmitted through the transmission gear 3052 and the transmission gear ring 3053, thereby smoothly driving the inner filter ring structure 302 to rotate. The transmission gear ring 3053 is fixedly installed on the outer ring of the inner filter ring structure 302. The inner filter ring structure 302 is provided with a plurality of interception structures 306 distributed along the inner ring of the inner filter ring structure 302. The interception structure 306 includes a plurality of mounting guide sleeves 3064, which are mounted on the inner filter ring structure 302. An interception rod 3061 is slidably connected in each of the plurality of mounting guide sleeves 3064. The installation of guide sleeve 3064 ensures the smooth sliding of interceptor bar 3061. Multiple interceptor bars 3061 have one end fixedly connected to the same connecting strip 3062. Both ends of the connecting strip 3062 are fixedly connected to guide wheels 3063. The guide wheels 3063 are slidably connected in an annular guide groove 304. The annular guide groove 304 includes an arc-shaped section 3041 and an arc-shaped protruding section 3042. The guide wheels 3063 can maintain normal movement along the arc-shaped section 3041, allowing the interception structure 306 to perform interception operations smoothly. When the guide wheels 3063 enter the arc-shaped protruding section 3042, the guide... The guide wheel 3063 rises in advance, causing the intercepting rod 3061 to retract, thus clearing away debris. When the guide wheel 3063 enters the arc-shaped section 3041 along the arc-shaped protrusion section 3042, it resets downwards, allowing the intercepting rod 3061 to smoothly reset for the next round of interception. The arc-shaped section 3041 and the arc-shaped protrusion section 3042 transition smoothly. The two ends of the multiple interception structures 306 are respectively located in two annular guide grooves 304. The annular guide grooves 304 are formed on an annular mounting rail 303, which is fixedly connected to the fixed outer cavity 301.
[0021] In this embodiment: multiple interception structures 306 are combined to form a debris barrier, allowing water flow to pass through which debris and larger silt can be intercepted, achieving a pretreatment effect. Next, the drive motor 3051 drives the transmission gear 3052 to rotate, and the transmission gear 3052 drives the transmission gear ring 3053 to rotate, which in turn drives the inner filter ring structure 302 to rotate, allowing the interception structure 306 to rotate at a uniform speed. This allows the interception structure 306 to alternately enter the lowered interception area. When one end of the interception structure 306 enters the arc-shaped protrusion section 3042, the interception structure 306 retracts, allowing debris and impurities to smoothly enter the collection component for collection. After cleaning, the interception structure 306 is reset and put back into use. This cycle ensures the interception effect and avoids the interception failure problem caused by long-term stress and debris coverage of traditional fixed interception structures, ensuring stable interception efficiency.
[0022] Example 2: Referring to Figures 4-6, a drainage structure for protecting water and soil resources in mountainous areas includes an impurity pretreatment mechanism 200. The impurity pretreatment mechanism 200 includes an impurity collection chamber 201, which is installed on a drainage ditch 101. Multiple collection chamber fixing frames 206 are fixedly connected to the impurity collection chamber 201 to secure it and ensure its stability. The multiple collection chamber fixing frames 206 are fixedly connected to a fixed outer cavity 301. A mesh filter structure 204 is installed below the impurity collection chamber 201. The bottom wall of the impurity collection chamber 201 and the mesh filter structure 204... Above the 4, an upper filter geotextile 205 is provided. The combination of the mesh filter structure 204 and the upper filter geotextile 205 can filter and separate residual fine mud and sand, which is convenient for mud and sand collection and subsequent treatment. It can also reduce residual moisture and reduce the difficulty of treatment. Both sides of the impurity collection chamber 201 are provided with collection chamber drain outlets 203. The collection chamber drain outlets 203 are provided with drain outlet side door structures 202. By opening the drain outlet side door structure 202, it is convenient to discharge impurities and mud and sand from the collection chamber drain outlets 203. One end of the impurity collection chamber 201 is placed in the fixed outer cavity 301, thereby collecting the impurities intercepted by the interception structure 306.
[0023] In this embodiment: the flexible and extensible nature of the interception structure 306 allows intercepted debris and impurities to fall smoothly into the impurity collection chamber 201 for collection. At the same time, the mesh filter structure 204 and the upper filter geotextile 205 work together to further separate mud, sand, debris and water, reducing the difficulty of subsequent treatment. Furthermore, the impurity collection chamber 201 is isolated from the composite drainage ditch 100, and workers can clean mud and sand through the sewage outlet side door structure 202 of the impurity collection chamber 201. This method can achieve pretreatment of larger debris, providing convenience for subsequent cleaning, reducing the difficulty of subsequent filtration, and improving drainage efficiency.
[0024] Example 3: Referring to Figures 1-3 and 7-8, a drainage structure for protecting water and soil resources in mountainous areas includes an automatic filtration and sewage discharge mechanism 300. The automatic filtration and sewage discharge mechanism 300 is located below the water source inlet 400, and an impurity pretreatment mechanism 200 is mounted on the automatic filtration and sewage discharge mechanism 300. The automatic filtration and sewage discharge mechanism 300 includes a fixed outer cavity 301 and an inner filter ring structure 302. The inner filter ring structure 302 is rotatably mounted on the fixed outer cavity 301 via bearings. The inner filter ring structure 302 is driven by a drive assembly 305. The inner filter ring structure 302 is provided with a plurality of interception structures 306 distributed along the inner ring of the inner filter ring structure 302. The two ends of the plurality of interception structures 306 are respectively located in two annular guide grooves 304. The annular guide grooves 304 are opened on an annular mounting rail 303, and the annular mounting rail 303 is fixedly connected to the fixed outer cavity 301.
[0025] In this embodiment: the driving component 305 drives the inner filter ring structure 302 to rotate, so that the interception structure 306 can alternately enter the interception area to intercept. After interception, it can carry the debris. When the interception structure 306 moves to the arc-shaped protrusion section 3042, it can generate a telescopic movement, which can smoothly discharge the debris into the collection component for collection. Its self-cleaning characteristics ensure that the intercepted debris continuously and evenly enters the collection component for separate collection. The separate collection function solves the problem of debris discharge, avoiding the impact of untimely cleaning on the interception effect, which would lead to the need for machine shutdown and increase the workload and difficulty of subsequent processing. The synergy of the two not only greatly improves the efficiency of sediment interception and recycling, but also ensures the long-term smooth flow of drainage channels, truly achieving the goal of water and soil separation and resource protection of "retaining soil and guiding clean water".
[0026] During water treatment operations, water flows into the interception area through the water source inlet 400. Multiple interception bars 3061 are combined to intercept debris and silt. The treated water flows directly into the mesh filter plate 102 and the upper filter geotextile 205 of the drainage ditch 101 for filtration. The filtered water is then discharged through the drainage ditch 101. During the interception process in the interception structure 306, the drive motor 3051 drives the transmission gear 3052 to rotate. The transmission gear 3052 drives the transmission gear ring 3053, which in turn drives the inner filter ring structure 302 to rotate. This causes the interception structure 306 to rotate and perform alternating interception operations. The intercepted debris follows the interception structure 306 towards... As the guide wheel 3063 moves upward along the arc-shaped section 3042 into the arc-shaped protrusion section 3041, the guide wheel 3063 drives the connecting bar 3062 and the intercepting rod 3061 to retract, allowing the debris to fall smoothly into the impurity collection chamber 201. When the guide wheel 3063 moves downward into the arc-shaped section 3041 along the slope of the arc-shaped protrusion section 3042, the intercepting rod 3061 extends and resets, ready to intercept again. The debris entering the impurity collection chamber 201 can be filtered by the upper filter geotextile 205 and the mesh filter structure 204, and the residual water can flow back to the composite drainage ditch 100 for discharge.
[0027] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
