Description

Technical Field

[0001] This application relates to the field of municipal drainage technology, and in particular to a municipal engineering road drainage filtration system. Background Technology

[0002] Urban road drainage systems are a crucial component of urban infrastructure, functioning to rapidly remove rainwater from roads and prevent flooding that could disrupt traffic and the urban environment. Traditional drainage systems typically collect water through road slopes into street gutters, which then flow through storm drains, connecting pipes, and manholes into main drainage pipes, ultimately discharging into nearby water bodies. With accelerating urbanization, the load on road drainage systems is increasing, placing ever higher demands on drainage efficiency and filtration effectiveness.

[0003] A related technology, CN213508829U, discloses a municipal engineering road drainage and filtration system. This system includes drainage wells installed on both sides of the road. The top of each drainage well is open, and a cover is provided at the open end of the well. Multiple water inlet holes are provided through the cover. A filter screen for filtering solid debris is slidably installed inside the drainage well. A lifting assembly is installed inside the drainage well to move the filter screen towards the open end of the well. A drainage pipe is connected to one side of the bottom of the drainage well. This application has the effect of improving the drainage function of the drainage wells.

[0004] Due to its inherent design features, the municipal road drainage filtration system described above has a clean water layer located below the baffle plate. This layout makes the maintenance and cleaning of the clean water layer extremely difficult. Workers must frequently disassemble the baffle plate to access the clean water layer for cleaning and inspection. This process is not only time-consuming and labor-intensive but may also lead to interruptions in the drainage system's operation. Frequent disassembly and installation of the baffle plate also increases component wear, thereby shortening the overall system's lifespan and increasing maintenance costs and replacement frequency. Utility Model Content

[0005] To address the challenges posed by the design of current municipal road drainage filtration systems, where the purification layer is located below the guide plate, maintenance and cleaning become difficult. Workers must disassemble the guide plate to access the purification layer, which is not only time-consuming and labor-intensive but may also disrupt the normal operation of the drainage system. Furthermore, frequent disassembly of the guide plate can lead to component wear and shorten the system's lifespan. This application provides a municipal road drainage filtration system.

[0006] The municipal engineering road drainage filtration system provided in this application adopts the following technical solution: it includes a drainage ditch and a filter box set on the upper end of the drainage ditch. The filter box includes a primary filtration unit set on the end of the filter box that is connected to the drainage ditch away from the filter box, a water purification layer set on the filter box, a fixing member set between the water purification layer and the filter box, a first guide plate set between the lower end of the water purification layer and the drainage ditch, and a first drainage pipe connected to the first guide plate.

[0007] It also includes a side drainage section connected to the water purification layer and the filter box, a drainage connection pipe between the side drainage section and the water purification layer, a second guide plate evenly distributed on both sides of the lower end face of the side drainage section, and a second drainage pipe located at the middle of the lower end face of the side drainage section.

[0008] By adopting the above technical solution, rainwater is first filtered through the primary filtration unit, and then enters the water purification layer for deep purification. The purified rainwater is discharged through the first guide plate and the first drainage pipe, while the deposited rainwater is guided by the side drainage section and the second guide plate to the second drainage pipe for discharge, thereby ensuring the efficient operation of the filtration system and improving drainage quality and efficiency.

[0009] As a preferred embodiment, the secondary filtration unit includes an overflow plate fixedly disposed on the upper surface of the filter housing and an overflow grille uniformly disposed on the overflow plate relative to the clean water layer.

[0010] By adopting the above technical solution, when water flows through the overflow plate and overflow grille, it can not only effectively remove the debris deposited on the overflow plate, but also reduce the impact on the water purification layer to a certain extent and extend the service life of the water purification layer. The overflow grille facilitates the sorting and guidance of the rainwater discharge direction, thereby making it easier for rainwater to enter the water purification layer.

[0011] As a preferred embodiment, the water purification layer includes a water purification frame, filter units uniformly arranged within the water purification frame, and partitions disposed between adjacent filter units. The outer periphery of the partitions is fixedly connected to the water purification frame, and the partitions facilitate the isolation of adjacent filter units. Each filter unit consists of several filter plates, and the number of filter holes on the filter plates decreases sequentially in the direction of rainwater falling.

[0012] By adopting the above technical solution, it is convenient to filter rainwater in multiple stages through the filter plate. The water purification frame is used to accommodate all the filter units and maintain the stability of the overall structure. The partition separates adjacent filter units to prevent rainwater from flowing back and forth during the filtration process, ensuring that each filter unit can complete the filtration work independently. The filter plate achieves step-by-step filtration by setting multiple filter holes with a progressively decreasing number of holes in the direction of rainwater falling, effectively removing impurities and pollutants from the rainwater.

[0013] As a preferred embodiment, it also includes a sealing cover plate fixedly installed on one side of the filter unit and a maintenance port installed on one side of the filter housing that is adapted to the sealing cover plate. The sealing cover plate is configured as a "T" shape, and a sealing rubber is provided at the connection between the sealing cover plate and the maintenance port.

[0014] By adopting the above technical solution, the design of the sealing cover makes it more convenient to maintain and clean the filter unit. Its "T"-shaped structure and the combination of the sealing rubber strip ensure that good sealing is maintained when the maintenance port is opened for cleaning, preventing debris from entering and rainwater from leaking out. The maintenance port is the channel to enter the internal filter unit for cleaning, which makes it easy to clean and maintain the filter unit according to actual usage needs.

[0015] As a preferred embodiment, the fixing component includes a U-shaped connector evenly distributed around the outer periphery of the water purification frame, a connecting rod for connecting the open ends of the U-shaped connector, and a fixing pin that passes through the overflow plate and connects to the U-shaped connector. The lower end face of the connecting rod is tangent to the upper end face of the water purification frame.

[0016] This makes it easier to fix the water purification frame between the U-shaped connector and the connecting rod.

[0017] As a preferred embodiment, the overflow plate is provided with mounting holes that are compatible with the fixing pins.

[0018] By adopting the above technical solution, a stable fixed structure is formed by evenly arranged U-shaped connectors and connecting rods. Then, the U-shaped connectors and overflow plate are connected by fixing pins, thereby installing the water purification layer inside the filter box. This design makes the entire device easy to install and quick to disassemble, effectively improving the installation efficiency of the water purification frame inside the filter box, and facilitating rapid adjustment and maintenance of the water purification layer according to actual needs.

[0019] As a preferred embodiment, one end of the drain connection pipe is connected to both sides of the water purification frame, and the other end of the drain connection pipe is connected to the side drain section.

[0020] By adopting the above technical solution, it is easier to discharge rainwater deposited on the water purification layer through the drainage connection pipe, thereby eliminating rainwater that may be deposited on the water purification layer and avoiding excessive water accumulation area that may affect the filtration effect.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. The filter box is the core part of the system. The primary filter unit set on its upper surface can initially intercept larger impurities and reduce the load entering the water purification layer.

[0023] 2. The water purification layer further removes fine impurities and contaminants through multiple layers of filter material. The fasteners ensure that the water purification layer can be firmly fixed in the filter box, while the first guide plate guides the filtered clean rainwater to flow downwards and is discharged through the first drainage pipe.

[0024] 3. The side drainage section is designed to remove rainwater that may accumulate in the clean water layer, preventing excessive water accumulation that could affect the filtration effect. Second guide plates are evenly distributed on both sides of the lower end face of the side drainage section to ensure uniform rainwater distribution. The second drainage pipe collects and discharges this side-drained rainwater. Attached Figure Description

The water purification frame 2 is used to accommodate all the filter units 21 and maintain the stability of the overall structure. The partitions 20 isolate adjacent filter units 21 to prevent rainwater from flowing back during the filtration process, ensuring that each filter unit 21 can complete the filtration work independently.
