Abstract
Description
Technical Field
[0001] This utility model relates to the field of road drainage technology, and in particular to a municipal road drainage structure that facilitates debris removal. Background Technology
[0002] Urban roads are distributed throughout cities, serving as the main arteries for pedestrian and vehicular traffic and playing a crucial role in transportation. Underground drainage systems are typically designed beneath urban roads. These systems generally consist of storm drains, sedimentation tanks, inspection manholes, sewers, and main underground drainage canals. The storm drains within these systems collect rainwater from the roads and discharge it into the main underground drainage canals, preventing flooding during heavy rains.
[0003] Most underground drainage systems use manhole covers and storm drain grates 21, which are frequently clogged by debris such as branches, leaves, and stones left on the road, slowing down rainwater drainage and affecting urban traffic. While existing storm drains are designed with anti-clogging mechanisms, clearing debris requires opening the manhole cover for manual cleaning or removing the storm drain grate 21 to clean the road drainage outlet 14. However, this is very inconvenient for cleaning sand and silt deposited in storm drains and sewers.
[0004] Therefore, it is necessary to provide a municipal road drainage structure that facilitates debris removal in order to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a municipal road drainage structure that facilitates debris removal. It can use a submersible sand pump to pump and transport the sediment deposited in the drainage area to the sediment placement area, which facilitates subsequent manual cleaning and completes the silt removal work of the drainage area.
[0006] To achieve the above objectives, the technical solution proposed by this utility model is as follows: a municipal road drainage structure that facilitates debris removal, comprising:
[0007] The drainage ditch has a drainage area and a sediment placement area separated from the drainage area. The drainage ditch has a pre-reserved installation port that communicates with the drainage area. The drainage ditch is buried underground, and the installation port is exposed on the road surface.
[0008] A water filtration mechanism, comprising a rain grate, a fluid filtration component, and a mounting plate with a water trough, wherein the mounting plate with the water trough is installed at the installation port of the drainage trough, the fluid filtration component is detachably installed on the mounting plate with the water trough, and the rain grate is detachably installed on the fluid filtration component.
[0009] A submersible sand suction pump is installed at the bottom of the drainage area and is connected to the silt and sand storage area via a sewage pipe.
[0010] A drain pipe, which is connected to the drainage area.
[0011] Preferably, the drainage area of the drainage trough is provided with a drainage outlet, and the drainage pipe is connected to the drainage outlet of the drainage area.
[0012] Preferably, an electrical conduit is installed in the drainage area, and the power cord of the submersible sand suction pump is housed inside the electrical conduit.
[0013] Preferably, the electrical conduit and the sewage pipe are arranged adjacent to each other, and both the electrical conduit and the sewage pipe are installed on the outside of the silt and sand placement area.
[0014] Preferably, the rain grate has multiple water inlet holes, the fluid filtration component is a circular filter cylinder, and the bottom of the fluid filtration component has multiple evenly spaced filter holes.
[0015] Preferably, the water filtration mechanism includes a base plate, on which mounting holes are formed, and the circular filter cylinder is installed at the mounting holes.
[0016] Preferably, the mounting plate with the water tank has multiple load-bearing beams above the water tank, and the base plate is mounted on the load-bearing beams.
[0017] Preferably, the rain grate has multiple grid holes, the fluid filtration component is a square filter tank, and the bottom of the fluid filtration component has multiple filter holes evenly spaced.
[0018] Compared with existing technologies, the beneficial effects are as follows: 1) When encountering heavy rain, rainwater on the road surface enters the fluid filtration component through the rain grate. The rain grate can intercept debris (such as plastic bags, branches, leaves, and larger stones) in the rainwater for primary filtration. The fluid filtration component performs secondary filtration to intercept the remaining debris in the rainwater, which can prevent too much debris from entering the drainage area of the drainage trough. The rainwater then flows to the drainage area through both ends of the water trough with the mounting plate with the water trough. Then the drainage pipe discharges the rainwater in the drainage area into the sewer and the underground drainage main canal.
[0019] 2) If there is too much sediment in the drainage area, when the submersible sand pump is connected to the external power supply, the submersible sand pump will start to pump and transport the sediment in the drainage area through the sewage pipe to the sediment placement area, which will facilitate manual cleaning later, thus completing the dredging work of the drainage area.

[0034] Please see Figures 1 to 2 This utility model proposes a municipal road drainage structure that facilitates debris removal, comprising:
[0035] The drainage ditch 1 has a drainage area 11 and a mud and sand placement area 12 separated from the drainage area 11. The drainage ditch 1 has a reserved installation port 13 communicating with the drainage area 11. The drainage ditch 1 is buried underground, and the installation port 13 is exposed on the road surface.
[0036] The water filtration mechanism 2 includes a rain grate 21, a fluid filtration component 22, and a mounting plate 23 with a water tank. The mounting plate 23 with the water tank is installed at the installation port 13 of the drainage trough 1. The fluid filtration component 22 is detachably installed on the mounting plate 23 with the water tank, and the rain grate 21 is detachably installed on the fluid filtration component 22.
[0037] A submersible sand suction pump 3 is installed at the bottom of the drainage area 11 and is connected to the sediment placement area 12 via a sewage pipe 4.
[0038] Drain pipe 5, which is connected to the drainage area 11 of drainage trough 1.
[0039] Thus, in the drainage trough 1, a pre-set drainage area 11 and a sediment placement area 12 are constructed, and the water filtration mechanism 2 is entirely distributed at the installation port 13. During heavy rain, rainwater on the road surface enters the fluid filtration component 22 through the rainwater grate 21. The rainwater grate 21 intercepts debris (e.g., plastic bags, branches, leaves, large stones, etc.) in the rainwater for primary filtration. The fluid filtration component 22 then performs secondary filtration to remove any remaining debris from the rainwater, preventing excessive debris from entering the drainage area 11 of the drainage trough 1. The rainwater then flows through both ends of the water trough on the mounting plate with the water trough to the drainage area, and finally, the drainage pipe 5 discharges the rainwater in the drainage area 11 into the sewer and the main underground drainage channel.
[0040] If too much silt accumulates in drainage area 11, the submersible sand pump 3 will start to pump the silt accumulated in drainage area 11 through the sewage pipe 4 to the silt placement area 12 when the external power supply is connected. This facilitates manual cleaning later and completes the silt removal work of drainage area 11.
[0041] The fluid filter component 22 is detachably mounted on the mounting plate 23 with a water tank, and the rain grate 21 is detachably mounted on the fluid filter component 22. The advantage of this design is that, under long-term use, the rain grate 21 and fluid filter component 22 may become clogged. This design, by making the rain grate 21 and fluid filter component 22 detachable, allows for easy removal and unclogging. Furthermore, the rain grate 21 and fluid filter component 22 may become damaged, deformed, or corroded. This design, by making the rain grate 21 and fluid filter component 22 detachable, allows for easy disassembly and replacement with new ones.
[0042] In a preferred embodiment, the drainage area 11 of the drainage trough 1 is provided with a drain outlet 14, and the drain pipe 5 is connected to the drain outlet 14 of the drainage area 11. It should be noted that in this embodiment, there are two drain outlets 14, which can be used as an inlet and an outlet, respectively, and each inlet and outlet is connected to a drain pipe 5. In actual application, the height of the inlet in the drainage area 11 can be higher than the height of the outlet in the drainage area 11, or the height of the inlet in the drainage area 11 can be equal to the height of the outlet in the drainage area 11, and can be flexibly designed and selected according to the actual working conditions.
[0043] In a preferred embodiment, an electrical conduit 6 (made of insulating material, such as plastic) is provided in the drainage area 11. The power cord of the submersible sand suction pump 3 is housed in the electrical conduit 6 and electrically connected to an external power source. This can prevent the power cord from being cut and leaking electricity, which could damage the submersible sand suction pump 3 and thus provide protection.
[0044] In a preferred embodiment, the electrical conduit 6 and the sewage pipe 4 are arranged adjacent to each other, and both the electrical conduit 6 and the sewage pipe 4 are fixedly installed on the outside of the silt and sand placement area 12. By fixing the electrical conduit 6 and the sewage pipe 4, the flow of rainwater in the drainage area 11 can be prevented from impacting the electrical conduit 6 and the sewage pipe 4, thus avoiding shaking or loosening of the sewage pipe 4 and the electrical conduit 6, and shortening the service life of the electrical conduit 6, the submersible sand pump 3, and the sewage pipe 4.
[0045] Please see Figures 3 to 6 In the first embodiment, the rain grate 21 has multiple water inlet holes, and the fluid filter component 22 is a circular filter cylinder with multiple evenly spaced filter holes at its bottom. It should be noted that in this embodiment, the apertures of the water inlet holes and filter holes can be designed according to actual application conditions.
[0046] In a preferred embodiment, the water filtration mechanism 2 includes a base plate 24, on which a mounting hole 241 is formed, and the circular filter cylinder is fixedly installed at the mounting hole 241. It should be noted that in this embodiment, the base plate 24 is L-shaped, and the circular filter cylinder can be installed at the mounting hole 241 by welding.
[0047] In a preferred embodiment, the mounting plate 23 with the water tank is generally U-shaped, and the mounting plate 23 with the water tank has a plurality of load-bearing beams 231 above the water tank, and the base plate 24 is mounted on the load-bearing beams. In this way, by designing the load-bearing beams, the stress strength of the base plate 24 can be increased, and the base plate 24 can be prevented from bending deformation.
[0048] Please see Figure 7In the second embodiment, the rainwater grate 21 has multiple grid holes, and the fluid filtering component 22 is a square filter tank with multiple evenly spaced filter holes at its bottom. It should be noted that in this embodiment, the size of the grid holes and the aperture of the filter holes can be selected and designed according to actual application conditions.
[0049] Among them, such as Figure 6 As shown, multiple water filtration mechanisms 2 can be continuously applied in a line on the ditch according to actual working conditions to filter the sewage flowing into the ditch.
[0050] When encountering heavy rain, rainwater on the road surface enters the fluid filtration component 22 through the rain grate 21. The rain grate 21 can filter out debris (such as plastic bags, branches, leaves, and larger stones) in the rainwater in the first stage. The fluid filtration component 22 performs a second filtration to filter out the remaining debris in the rainwater, which can prevent too much debris from entering the drainage area 11 of the drainage trough 1. The rainwater then flows to the drainage area through both ends of the water trough with the mounting plate with the water trough. Then, the drainage pipe 5 discharges the rainwater in the drainage area 11 into the sewer and the underground drainage main canal.
[0051] If too much silt accumulates in drainage area 11, the submersible sand pump 3 can be connected to an external power source periodically. When the submersible sand pump 3 is working, it will start to pump the silt accumulated in drainage area 11 and transport it to silt storage area 12 through sewage pipe 4. This will facilitate the later manual cleaning of the silt piled up in the silt storage area, thus completing the dredging work of drainage area 11.
[0052] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
