Description

Technical Field

[0001] This utility model relates to the field of sediment collector technology, and in particular to a sediment collector for soil erosion in small drainage ditches. Background Technology

[0002] Drainage ditches are important drainage facilities in areas such as farmland, roads, and construction sites, but soil erosion often occurs during their use due to natural or human factors.

[0003] Small drainage ditch sediment collectors are devices used for soil and water conservation monitoring, primarily to collect sediment from runoff plots to assess soil erosion. Their general structure includes an inlet, a sediment collection container, and an outlet, and they are typically placed in the riverbed at the base of the slope to collect sediment from runoff. Existing traditional small drainage ditch sediment collectors have many problems. For example, there are few sediment collectors on the market specifically designed for small drainage ditches. Most use large equipment, which increases costs and makes it difficult to achieve the desired effect. In addition, traditional small drainage ditch sediment collection generally uses a single filter screen, which is not only easy to clog, but also has relatively low collection efficiency.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] This embodiment provides a soil and sediment collector for small drainage ditches, such as... Figure 4 and 5 As shown, it includes: a first baffle 11 and a second baffle 15, with a drainage channel formed between the first baffle 11 and the second baffle 15; a first sediment collection part is provided outside the first baffle 11; a second sediment collection part is provided outside the second baffle 15; it also includes: a first filter part, which is located in the drainage channel and is used for the initial filtration of sediment in the water and soil. The second filtration section is located inside the drainage channel and below the first filtration section, and is used to filter the mud and sand in the water and soil again.

[0017] The first sediment collection unit includes two first drainage holes 8 opened on the first baffle 11, a first sediment storage box 17 fixedly installed on the outside of the first baffle 11, and a first drainage net 7 fixedly installed on the outside of the first sediment storage box 17 for drainage; the second sediment collection unit includes two second drainage holes 12 opened on the second baffle 15, a second sediment storage box 18 fixedly installed on the outside of the second baffle 15, and a second drainage net 14 fixedly installed on the outside of the second sediment storage box 18 for drainage. The first filtration section includes a first drawer 13 slidably disposed at the upper end between the first baffle 11 and the second baffle 15. A first filter screen 1 is fixedly installed on the first drawer 13 for initial filtration of sediment. Figure 3 As shown, two rows of symmetrical first filter leaves 5 are fixedly installed on the first filter screen 1; The second filtration section includes a second drawer 16, which is slidably disposed below the first drawer 13. A second filter screen 4 is fixedly installed on the second drawer 16 for secondary filtration of mud and sand. Two rows of mutually symmetrical second filter leaves 2 are fixedly installed on the second filter screen 4. The first filter leaves 5 and the second filter leaves 2 can slow down the flow rate of mud and water.

[0018] Pull out the first drawer 13 and the second drawer 16 to facilitate cleaning of the sediment and make the first drawer 13 and the second drawer 16 reusable.

[0019] like Figure 4 A second baffle plate 6 and a first baffle plate 10 are fixedly installed at the outer ends between the first baffle plate 11 and the second baffle plate 15. A third filter screen 3 for filtering large-volume debris is fixedly installed on the second baffle plate 6, and a water inlet pipe 9 is installed through the first baffle plate 10. Figure 2 As shown, the water inlet pipe 9 extends inward through the second baffle plate 6 and slopes downward.

[0020] like Figure 2 As shown, the two first drainage holes 8 are parallel on the first baffle 11, and the two second drainage holes 12 are parallel on the second baffle 15.

[0021] like Figure 1 As shown, the central portion of the first filter 1 and the second filter 4 is convex and wedge-shaped.

[0022] The first filter screen 1 uses a 30-mesh filter screen to filter mud and sand with a particle size of 0.5-0.85mm; the second filter screen 4 uses a 40-mesh filter screen to filter mud and sand with a particle size of 0.25-0.6mm; the first drainage screen 7 and the second drainage screen 14 use 60-mesh filter screens to filter mud and sand with a particle size of 0.15-0.4mm.

[0023] In use, the collector is first placed in the drainage ditch downstream of the drainage channel. The sand-laden water in the drainage ditch enters the device through the inlet pipe 9. The downward-sloping design of the inlet pipe 9 reduces water flow impact, allowing the water to flow more smoothly into the interior. The water first contacts the third filter screen 3 on the second baffle plate 6, which filters out large debris such as branches, stones, and plastics, preventing subsequent filter screens from becoming clogged. The pre-treated water enters the space between the first baffle plate 11 and the second baffle plate 15, first flowing through the first filter screen 1 on the first drawer 13. The first filter screen 1 has a wedge-shaped protrusion design with a high center and low edges, which guides the water flow to both sides, making it easier for sediment to settle on the filter screen surface and intercepting some larger particles of sediment. At the same time, the two rows of symmetrically distributed first filter leaves 5 on the first filter screen 1 block the water flow, significantly reducing the water velocity. After the flow velocity slows down, the sediment settles more easily on the surface of the first filter screen or falls into the space below due to gravity, improving the initial filtration efficiency. The second filter screen 4 also features a wedge-shaped protrusion design, further intercepting fine particles of silt and achieving graded filtration from coarse to fine. The second filter leaf 2 on the second filter screen 4 further slows down the water flow, providing a double deceleration design, enhancing the settling effect, allowing the remaining fine sand to settle fully, and improving the silt separation efficiency. The clean water after two stages of filtration flows into the first sludge storage tank 17 and the second sludge storage tank 18 on both sides through the first drain hole 8 of the first baffle 11 and the second drain hole 12 of the second baffle 15, respectively. The first drain net 7 and the second drain net 14 on the outside of the sludge storage tanks perform a final filtration of the water flow. Finally, the filtered water flows out along the first drain net 7 and the second drain net 14, and the filtered silt accumulates in the first sludge storage tank 17 and the second sludge storage tank 18, respectively. The upper parts of the first sludge storage tank 17 and the second sludge storage tank 18 are open to facilitate the removal of silt from inside.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
