Technical Field
[0001] This utility model relates to the field of road construction drainage technology, specifically a drainage device with anti-clogging function. Background Technology
[0002] Municipal road drainage refers to the measures taken to remove water accumulated on the road surface. Usually, water on the road surface flows into the street ditch according to the slope of the road surface, and then flows into the drainage pipe through the rainwater inlet from the street ditch. Finally, it is discharged from the outlet of the drainage pipe to a nearby sewage pond or water body such as a river, lake, or sea. The drainage of water on urban roads should be rapid and smooth, and water should not accumulate on the road surface to form a water film, which would affect driving. Drainage devices are used to drain water, and sometimes they also play a role in water storage and retention.
[0003] Existing patent CN219794149U proposes a road drainage anti-clogging device, in which a screening plate seat is inclinedly set at the bottom of the drainage cover, a water filter screen is provided on the upper part of the screening plate seat, a debris collection trough is provided on one side of the drainage trough seat, and a connecting slot is provided on the side of the debris collection trough that connects with the drainage trough seat. The debris collection trough is connected to the drainage trough seat through the connecting slot. This device can effectively prevent debris from accumulating at the bottom of the drainage trough seat.
[0004] However, this drainage device still has some drawbacks. During use, the filter screen holes are prone to accumulating impurities, which affects the filtration effect and reduces the drainage volume. Cleaning the filter screen holes is also quite cumbersome. In addition, the accumulation of debris in the debris collection tank can clog the filter screen, affecting the drainage effect. Furthermore, the debris collection tank is easy to clean.
[0005] Based on this, a drainage device with anti-clogging function is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] In one embodiment, such as Figure 1 - Figure 4 As shown, a drainage device with anti-clogging function includes a drainage tank 1. Two drainage channels 11 are opened on both sides inside the drainage tank 1. A connecting channel 12 is opened on the top inside the drainage tank 1. A fixing channel 13 is opened in the middle inside the drainage tank 1. Two limiting rods 14 are installed on both sides inside the fixing channel 13. A fixing frame 15 is installed in the middle of the drainage channel 11.
[0030] A drainage assembly is placed on the right side of the drainage trough 11;
[0031] A filter assembly is provided in the middle of the left side of the drainage trough 11;
[0032] A collection component is placed on the top of the fixed frame 15. The collection component includes a limiting frame 3. The limiting frame 3 is placed on the top of the fixed frame 15. Two handles 31 are installed on the top two sides of the limiting frame 3. A frame 32 is installed at the bottom of the limiting frame 3. A filter screen 33 is installed around the frame 32 and at the bottom.
[0033] The frame 32 is wrapped with a water filtration assembly on its outer side.
[0034] In this embodiment, the movement of the filter assembly is limited by the limiting rod 14, the collection assembly is supported by the fixing frame 15, the frame 32 is supported by the limiting frame 3, the water is filtered out by the filter screen 33 on the outside of the frame 32, which also serves as a support, and the water filtration assembly wraps the outer layer of the frame 32 to perform double-layer filtration.
[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, a first drainage cover 16 is placed on the left side of the drainage trough 11. An opening groove 17 is provided on one side of the first drainage cover 16. The first drainage cover 16 intercepts large pieces of impurities and garbage, and the opening groove 17 allows the handle 22 to slide inside it.
[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the drainage assembly includes a second drainage cover 18, which is placed on the right side of the drainage trough 11. Two support plates 19 are installed on both sides of the bottom of the second drainage cover 18, and a guide plate 110 is installed at the bottom of the support plate 19. The second drainage cover 18 intercepts large impurities, the support plates 19 support the guide plate 110, and the guide plate 110 guides the sewage to the top of the filter plate 21.
[0037] In one embodiment, such as Figure 1 and Figure 2 As shown, a water outlet assembly is installed at the bottom of the drainage tank 1, through which sewage is discharged.
[0038] In one embodiment, such as Figure 1 and Figure 2 As shown, the water outlet assembly includes a water outlet frame 111, which is installed at the bottom of the drain tank 1. A water guide plate 112 is installed on one side of the inside of the water outlet frame 111, and a drain pipe 113 is installed on one side of the water outlet frame 111. The sewage is treated by the water outlet frame 111 and then discharged through the drain pipe 113.
[0039] In one embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the filter assembly includes a support frame 2, which is placed inside the drain trough 11 on the left side. A filter plate 21 is installed in the middle of the support frame 2. A handle 22 is rotatably connected to the top side of the support frame 2. The handle 22 is slidably connected inside the opening slot 17. Two sliding grooves 23 are opened on the right side of the support frame 2. The sliding grooves 23 are slidably connected to the limiting rod 14. By pulling the handle 22, the left side of the support frame 2 moves upward, so that the sliding grooves 23 slide outside the limiting rod 14, thereby connecting and supporting the support frame 2, causing the filter plate 21 to shake and send impurities into the collection assembly.
[0040] In one embodiment, such as Figure 1 and Figure 4 As shown, the water filtration assembly includes a metal mesh 34, which is wrapped around the outside of the frame 32. The metal mesh 34 is woven from fine metal wires. Through the small aperture of the metal mesh 34, impurities and garbage are filtered out, avoiding the problem of clogging.
[0041] The above embodiment discloses a drainage device with anti-clogging function. Larger impurities in the sewage are filtered and intercepted by the first drain cover 16 and the second drain cover 18. The guide plate 110 is supported by the bottom support plate 19 of the second drain cover 18. The guide plate 110 guides the sewage through the connecting channel 12 into the interior of the left drain trough 11. The sewage is filtered by the filter plate 21 inside the support frame 2, removing impurities and garbage. The sewage is then guided into the collection assembly by the slope of the support frame 2. Garbage and impurities are intercepted and collected by the filter screens 33 around and at the bottom of the frame 32, facilitating garbage collection. The metal mesh 34 wrapped around the outside of the frame 32 further facilitates the removal of garbage and impurities from the sewage. The device effectively intercepts dust and impurities, preventing blockages and improving its practicality. When excessive impurities accumulate above the filter plate 21, pulling the handle 22 moves the left side of the support frame 2 upwards, causing the sliding groove 23 to slide outside the limit rod 14, thus connecting and supporting the support frame 2. This causes the filter plate 21 to vibrate, sending impurities into the collection assembly. When cleaning the collection assembly is required, the first drain cover 16 and the second drain cover 18 are removed, and the handle 22 is pulled to move the support frame 2 upwards, preventing obstruction of the collection assembly. The collection assembly can then be removed for cleaning by pulling the two handles 31. This enhances the practicality and convenience of the device and improves its anti-clogging effect.
[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
