Description

Technical Field

[0001] This utility model relates to the field of water guiding equipment technology, specifically a slope runoff buffer and sediment filtration device. Background Technology

[0002] When rainfall falls to the ground, it must be intercepted by plants, infiltrated, filled in depressions, and evaporated. When the soil moisture content in the vadose zone reaches saturation or the rainfall intensity exceeds the soil surface infiltration capacity, the remaining water forms many small, dispersed water flows that sometimes merge and sometimes separate, namely slope runoff. On a flat slope or during heavy rainstorms, it can extend into sheet-like or gully-like flows, thus forming slope runoff.

[0003] Slope runoff is mainly caused by insufficient slope collection and drainage capacity. Continuous slope runoff can easily lead to soil erosion and gully formation, and in severe cases, it can cause risks such as landslides and debris flows. The most common method at present is to reinforce the slope by setting up grass grids or constructing reinforced concrete surfaces to guide water and drain water. Both methods have their shortcomings. Grass grids and other methods that rely on plants to stabilize the soil and drain water are time-consuming and slow to take effect, while concrete structures are expensive to construct. They lack a simple function that can alleviate slope runoff and accelerate drainage.

[0004] Now, a novel slope runoff buffering and sediment filtration device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a slope runoff buffer and sediment filtration device to solve the problem of slope runoff that cannot be quickly alleviated as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slope runoff buffer and sediment filtration device, comprising an arc-shaped water guide plate, a U-shaped half-pipe fixedly connected to the bottom end of the arc-shaped water guide plate, V-shaped grooves respectively provided on the left and right sides of the arc-shaped water guide plate, an arc-shaped filter plate fixedly connected to the top end of the U-shaped half-pipe, multiple sets of sediment filtration holes opened inside the arc-shaped filter plate, three sets of positioning plates fixedly connected to the top end of the arc-shaped water guide plate, positioning holes opened inside the positioning plates, positioning rods inserted into the positioning holes, positioning rings welded to the top end of the positioning rods, and hammer blocks welded to the top end of the positioning rods.

[0007] As a further technical solution of this utility model, the left and right sides of the arc-shaped water guide plate and the U-shaped half-pipe are flush, and the bottom end of the arc-shaped water guide plate and the top end of the U-shaped half-pipe have the same curvature.

[0008] As a further technical solution of this utility model, the arc-shaped water guide plate and the U-shaped half-pipe have the same thickness, and the arc-shaped water guide plate is arranged at equal intervals.

[0009] As a further technical solution of this utility model, the V-shaped grooves are symmetrically distributed about the vertical center line of the arc-shaped water guide plate, and the top end of the V-shaped grooves is flush with the bottom end of the U-shaped half-pipe.

[0010] As a further technical solution of this utility model, the mud and sand filter hole extends through both ends of the arc-shaped filter plate, and the left and right sides of the U-shaped half-pipe and the arc-shaped filter plate are flush.

[0011] As a further technical solution of this utility model, the bottom end of the positioning ring and the top end of the positioning piece are fitted together, and the outer diameter of the positioning rod and the inner diameter of the positioning hole are the same.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the slope runoff buffering and sediment filtration device not only realizes the function of buffering runoff and accelerating drainage, and the function of filtering sediment to prevent overflow, but also realizes the function of easy fixation. (1) By setting up an arc-shaped water guide plate, a U-shaped half-pipe and a V-shaped groove, when in use, an arc-shaped groove is pre-drilled on the slope where it is easy to form surface runoff. The arc-shaped pipe composed of the arc-shaped water guide plate and the U-shaped half-pipe is buried in the groove. The V-shaped groove is arranged on both sides of the slope at low points. When rainwater flows down the slope, it enters the U-shaped half-pipe directly along the arc-shaped water guide plate. The arc-shaped structure inside the U-shaped half-pipe alleviates the impact of water flow on the one hand, and guides it to both sides into the V-shaped groove on the other hand. It is discharged in a concentrated manner at the V-shaped groove. Multiple sets of arc-shaped water guide plates and U-shaped half-pipes work together to form a stepped structure, which reduces the runoff layer by layer. The overall cost is low and the layout is fast, realizing the function of buffering runoff and accelerating drainage. (2) By setting up an arc-shaped filter plate and a sediment filter hole, when the slope runoff enters the U-shaped half-pipe, it will roll upward under its own impact force. The water seeps out along the sediment filter hole on the arc-shaped filter plate. The sediment is intercepted in the U-shaped half-pipe and discharged to both sides. It is not easy to accumulate on the slope, thus achieving the function of filtering sediment and preventing overflow. (3) By setting up positioning plates, positioning holes, positioning rods, positioning rings and hammer blocks, when in use, as the arc-shaped pipeline composed of arc-shaped water guide plates and U-shaped half-pipes is buried in the trench, the positioning rods are inserted along the positioning holes on the positioning plates until the positioning rings are pressed against the positioning plates, thus completing the installation. The hammer blocks are convenient for hammering and pulling out, and the positioning rods can prevent the arc-shaped water guide plates and U-shaped half-pipes from being washed away by the water flow, thus realizing the function of easy fixation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figure 1-4 A slope runoff buffer and sediment filtration device includes an arc-shaped water guide plate 1, a U-shaped half-pipe 2 fixedly connected to the bottom end of the arc-shaped water guide plate 1, and V-shaped grooves 3 respectively provided on the left and right sides of the arc-shaped water guide plate 1. The left and right sides of the arc-shaped water guide plate 1 and the U-shaped half-pipe 2 are flush. The bottom end of the arc-shaped water guide plate 1 and the top end of the U-shaped half-pipe 2 have the same curvature. The thickness of the arc-shaped water guide plate 1 and the U-shaped half-pipe 2 is the same. The arc-shaped water guide plates 1 are arranged at equal intervals. The V-shaped grooves 3 are symmetrically distributed about the vertical center line of the arc-shaped water guide plate 1. The top end of the V-shaped grooves 3 and the bottom end of the U-shaped half-pipe 2 are flush, which facilitates buffering and guiding the slope runoff. Specifically, such as Figure 1 and Figure 2 As shown, an arc-shaped trench is pre-drilled on a slope prone to surface runoff. An arc-shaped pipe consisting of an arc-shaped water guide plate 1 and a U-shaped half-pipe 2 is buried in the trench. A V-shaped groove 3 is arranged on both sides of the slope at low points. When rainwater flows down the slope, it enters the U-shaped half-pipe 2 directly along the arc-shaped water guide plate 1. The arc-shaped structure inside the U-shaped half-pipe 2 not only reduces the impact of the water flow, but also guides it to both sides into the V-shaped groove 3, where it is discharged in a concentrated manner. Multiple sets of arc-shaped water guide plates 1 and U-shaped half-pipes 2 work together to form a stepped structure, reducing the runoff layer by layer. The overall cost is low and the deployment is quick.

[0017] The top of the U-shaped half-pipe 2 is fixedly connected to an arc-shaped filter plate 4. The arc-shaped filter plate 4 has multiple sets of mud and sand filter holes 5 inside. The mud and sand filter holes 5 pass through the front and rear ends of the arc-shaped filter plate 4. The left and right sides of the U-shaped half-pipe 2 and the arc-shaped filter plate 4 are flush, which facilitates the interception and filtration of mud and sand. Specifically, such as Figure 1 and Figure 3As shown, when the slope runoff enters the U-shaped half-pipe 2, it will roll upward under its own impact force. The water seeps out along the mud and sand filter holes 5 on the arc-shaped filter plate 4. The mud and sand are intercepted in the U-shaped half-pipe 2 and discharged to both sides, making it difficult to accumulate on the slope.

[0018] Three sets of positioning plates 6 are fixedly connected to the top of the arc-shaped water guide plate 1. The positioning plate 6 has a positioning hole 7 inside. A positioning rod 8 is inserted into the positioning hole 7. A positioning ring 9 is welded to the top of the positioning rod 8. A hammer block 10 is welded to the top of the positioning rod 8. The bottom end of the positioning ring 9 fits with the top of the positioning plate 6. The outer diameter of the positioning rod 8 is the same as the inner diameter of the positioning hole 7, which is convenient for fixing the equipment. Specifically, such as Figure 1 and Figure 4 As shown, insert the positioning rod 8 along the positioning hole 7 on the positioning piece 6 until the positioning ring 9 presses against the positioning piece 6, and the installation is completed. The hammer block 10 facilitates hammering and pulling out. The positioning rod 8 can prevent the arc-shaped water guide plate 1 and the U-shaped half-pipe 2 from being washed away by the water flow.

[0019] Working Principle: In use, this invention first involves creating an arc-shaped trench on a slope prone to runoff. An arc-shaped pipe system, consisting of an arc-shaped guide plate 1 and a U-shaped half-pipe 2, is then buried within the trench. V-shaped grooves 3 are positioned on the lower sides of the slope. As rainwater flows down the slope, it enters the U-shaped half-pipe 2 directly along the arc-shaped guide plate 1. The arc-shaped structure inside the U-shaped half-pipe 2 mitigates the impact of the water flow and guides it to both sides into the V-shaped grooves 3, where it is discharged. Multiple sets of arc-shaped guide plates 1 and U-shaped half-pipes 2 work together to form a tiered structure, progressively reducing runoff. The overall design is cost-effective and quick to deploy. When the runoff enters the U-shaped half-pipe 2, it is churned upwards by its own impact force. Water seeps out through the sediment filter holes 5 on the arc-shaped filter plate 4, where sediment is trapped and discharged to both sides, preventing accumulation on the slope. As the arc-shaped water guide plate 1 and the U-shaped half-pipe 2 are buried in the trench, the positioning rod 8 is inserted along the positioning hole 7 on the positioning plate 6 until the positioning ring 9 presses against the positioning plate 6, thus completing the installation. The hammer block 10 facilitates hammering and pulling out, and the positioning rod 8 can prevent the arc-shaped water guide plate 1 and the U-shaped half-pipe 2 from being washed away by the water flow.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
