Description

Technical Field

[0001] This utility model relates to the field of road drainage system technology, specifically an urban flood control drainage system. Background Technology

[0002] Urban flooding is a waterlogging disaster caused by heavy or continuous rainfall exceeding a city's drainage capacity. Its causes include climate change and problems in urban planning and construction. Since climate change is uncontrollable, improving drainage systems is particularly important in urban planning to prevent urban flooding.

[0003] In urban roads, storm drains, manholes, and sewers are often installed along the roadside to drain rainwater and prevent severe flooding that could render roads impassable. However, existing roadside sewers often retain rainwater, which carries away leaves and debris that haven't been swept away. While the drain openings on the drain grates can filter larger pieces of debris, a significant amount still flows into the manholes, severely impacting drainage efficiency and contributing significantly to urban flooding.

[0004] As garbage accumulates in the sewers over a long period of time, it will inevitably cause blockages in the drainage system. During routine road cleaning and garbage removal, manual cleaning is inconvenient due to the depth of the sewer wells, and the cleaning frequency is relatively low, creating a vicious cycle and posing a risk of urban flooding. Utility Model Content

[0005] In view of the shortcomings of existing technologies, this utility model provides an urban flood control drainage system to solve the problem that existing urban road sewer wells are prone to accumulating garbage and are inconvenient to clean, which leads to the risk of urban flooding.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An urban flood control drainage system includes a fixed frame and a grate movably mounted on the fixed frame. A detachable, open-bottomed secondary filter hopper is installed below the fixed frame. Drainage grooves are evenly distributed on the side walls of the secondary filter hopper. Handles are fixed on both sides of the inner wall of the secondary filter hopper near the top. A tertiary filter hopper is installed at the open bottom of the secondary filter hopper. Drainage holes are evenly distributed on the side walls and bottom of the tertiary filter hopper. A handle is movably hinged to the top edge of the tertiary filter hopper.

[0008] Preferably, the secondary filter bucket has an inverted frustum structure with a larger top and a smaller bottom, and the drain trough is horizontally arranged on the side wall of the secondary filter bucket.

[0009] Preferably, the drain trough is a long strip trough, and the width of the drain trough is smaller than the width of the upper and lower drain openings on the grate.

[0010] Preferably, the three-stage filter hopper has a sloping structure with its four sides converging towards the center.

[0011] Preferably, the drain hole is a round hole, and the diameter of the drain hole is smaller than the width of the drain groove.

[0012] Preferably, the top two sides of the secondary filter hopper are fixedly connected with connecting ears, and handle bolts connected to the fixed frame are installed on the connecting ears.

[0013] Preferably, the top of the tertiary filter bucket is provided with an outer flange, and the bottom of the side wall of the secondary filter bucket is provided with an inner flange. The tertiary filter bucket and the secondary filter bucket are installed by the outer flange and the inner flange being movably snapped together.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention features a detachable secondary and tertiary filter bucket with progressively increasing filtration levels located below the grate. Both the secondary and tertiary filter buckets have sloping sidewalls. As rainwater carrying debris flows downwards, it flows along these sidewalls. The gradually decreasing size of the drain outlet, drain trough, and drain holes gradually increases the filtration and interception effect on the debris, trapping most of it in the tertiary filter bucket. This not only provides excellent debris interception and filtration but also allows for easy removal of debris through the detachable design, preventing sewer blockages, reducing the risk of urban flooding, and solving the problem of existing urban road sewers accumulating debris and being difficult to clean, thus posing a risk of urban flooding.

[0021] 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.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: an urban flood control drainage system, including a fixed frame 1 and a grate 2 movably installed on the fixed frame 1. A detachable secondary filter hopper 3 with an open bottom is installed below the fixed frame 1. The secondary filter hopper 3 has an inverted frustum structure with a larger top and a smaller bottom. Drainage grooves 301 are evenly arranged on the side wall of the secondary filter hopper 3. The drainage grooves 301 are horizontally arranged on the side wall of the secondary filter hopper 3. The drainage grooves 301 are elongated grooves, and the width of the drainage grooves 301 is smaller than the width of the upper and lower water inlets 201 of the grate 2.

[0023] A tertiary filter 6 is installed at the bottom open position of the secondary filter hopper 3. The four sides of the tertiary filter hopper 6 are sloped structures that converge towards the center. Drainage holes 601 are evenly provided on the side walls and bottom of the tertiary filter hopper 6. The drainage holes 601 are round holes, and the diameter of the drainage holes 601 is smaller than the width of the drainage groove 301. A handle 7 is movably hinged to the top edge of the tertiary filter hopper 6.

[0024] Handles 5 are fixed on both sides of the inner wall of the secondary filter 3 near the top. Connecting ears 4 are fixedly connected to the top of the secondary filter 3 on both sides. Handle bolts 8 connected to the fixed frame 1 are installed on the connecting ears 4. The top of the tertiary filter 6 is provided with an outer flange 602. The bottom of the side wall of the secondary filter 3 is provided with an inner flange 302. The tertiary filter 6 and the secondary filter 3 are installed by the movable snap-fit ​​of the outer flange 602 and the inner flange 302.

[0025] Working principle:

[0026] When rainwater carrying garbage flows down through the drain 201 of the grate 2, the size of the drain 201 restricts the initial filtration and interception of larger garbage. Some garbage will flow into the secondary filter hopper 3. The side walls of the secondary filter hopper 3 and the tertiary filter hopper 6 are both sloping. When rainwater carrying garbage flows down, it will flow along the side walls. The gradually decreasing size of the drain 201, the drain groove 301, and the drain hole 601 gradually increases the filtration and interception effect on garbage, trapping most of the garbage in the tertiary filter hopper 6. The garbage interception and filtration effect is relatively good. When cleaning up garbage, the tertiary filter hopper 6 can be lifted up by hand or by using a tool to hook the handle 7 for easy garbage removal. If necessary, the secondary filter hopper 3 can also be disassembled by hand by removing the handle bolt 8. The detachable method makes it easy to remove garbage, avoids sewer blockage, and reduces the risk of urban flooding.
