Description

Technical Field

[0001] This utility model relates to the field of rainwater inlet technology, and in particular to an environmentally friendly rainwater inlet. Background Technology

[0002] Storm inlets are key facilities in urban drainage systems. They are usually located on both sides of roads, squares, or the edges of green belts. They are used to collect surface rainwater and guide it into underground drainage networks. Their core functions are rapid drainage and filtering to intercept debris, while also taking into account requirements such as preventing blockages and ease of maintenance.

[0003] In existing technologies, some initial rainwater is discharged directly into the municipal stormwater system without treatment, and the pipe openings accumulate silt and sand over time, leading to blockages. Due to the limited height of conventional environmentally friendly stormwater inlets, it is difficult to inspect and clean the connection pipes of the stormwater inlets, which affects normal drainage, increases the risk of road flooding, and consequently increases maintenance labor and costs. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an environmentally friendly rainwater inlet that can ensure smooth drainage and reduce maintenance costs without affecting the initial rainwater treatment effect.

[0005] According to an embodiment of the present invention, an environmentally friendly rainwater inlet includes a well body, the opening end of which is covered with a plurality of grates; a sedimentation chamber, which is located in the well body and corresponds vertically to the plurality of grates, and is used to remove large suspended particles from the water flow; a purification chamber, which is located in the well body and is connected to the sedimentation chamber, and is provided with a rainwater pipe connected to the municipal drainage system, which is used to discharge the water flowing in the purification chamber; and a filter wall, which is detachably located between the sedimentation chamber and the purification chamber, and is used to intercept sediment in the flowing water.

[0006] The environmentally friendly rainwater inlet according to the embodiments of this utility model has at least the following beneficial effects: Rainwater first enters the sedimentation chamber through several grates, where large suspended particles naturally settle under gravity. Subsequently, the water flows through the filter wall, whose porous structure effectively intercepts fine silt and prevents it from entering the purification chamber. The purified rainwater then enters the purification chamber and is discharged into the municipal drainage system through the rainwater pipe. Thus, through multi-stage filtration of grates, sedimentation chamber, and filter wall, the silt and suspended solids in the rainwater are effectively reduced, lowering the risk of blockage in the municipal drainage system. At the same time, the detachable design of the filter wall simplifies the maintenance process, improves cleaning efficiency, and extends the service life of the pipe network, thereby reducing operation and maintenance costs.

[0007] According to some embodiments of this utility model, the bottom elevation of the water purification chamber is higher than the bottom elevation of the sedimentation chamber.

[0008] According to some embodiments of the present invention, the filter wall includes multiple filter bricks, each of which is detachably connected to the well body 100. The multiple filter bricks are located between the sedimentation chamber and the water purification chamber, and are stacked sequentially in the vertical direction.

[0009] According to some embodiments of this utility model, a limiting groove is provided on the walls on opposite sides of the water purification chamber. The limiting groove is vertically arranged and corresponds to the width of the filter wall. The filter wall is movably disposed in the limiting groove to separate the water purification chamber and the grit chamber.

[0010] According to some embodiments of this utility model, it also includes a baffle plate, which is vertically installed on the top wall of the well body and extends downward from the top wall of the well body. The baffle plate is located on one side of the filter wall and in the sedimentation chamber. The baffle plate is used to guide the water flow from the sedimentation chamber to the clean water chamber to avoid short-circuiting or turbulence affecting the sedimentation effect.

[0011] According to some embodiments of this utility model, it also includes a weir plate, which is vertically installed on the wall of the well body. The weir plate is located between the filter wall and the debris barrier, and the top height of the weir plate is lower than the top height of the debris barrier. The weir plate is used to intercept scum and light debris on the water surface.

[0012] According to some embodiments of the present invention, the weir plate and the debris barrier plate have overlapping areas in the vertical direction.

[0013] According to some embodiments of the present invention, the bottom of the sedimentation chamber has an inclined portion, which is located at the end of the sedimentation chamber away from the clean water chamber. The inclined portion is inclined toward the clean water chamber and is configured to prevent gravel from accumulating in the horizontal section at the bottom of the well body.

[0014] According to some embodiments of this utility model, each grate is provided with a filter bucket at the bottom, and the opening end of the filter bucket corresponds to the size of the corresponding grate. The filter bucket is used to initially filter large-sized debris in the water flow.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0032] refer to Figures 1 to 5 This embodiment discloses an environmentally friendly rainwater inlet.

[0033] like Figures 1 to 5As shown, the environmentally friendly rainwater inlet includes a well body 100, a sedimentation chamber 200, a water purification chamber 300, and a filter wall 400. The opening end of the well body 100 is covered with several grates 110. The sedimentation chamber 200 is located in the well body 100, and the sedimentation chamber 200 and the several grates 110 are vertically aligned. The sedimentation chamber 200 is used to remove large suspended particles from the water flow. The water purification chamber 300 is located in the well body 100 and is connected to the sedimentation chamber 200. The water purification chamber 300 is equipped with a rainwater pipe 310 that is connected to the municipal drainage system. The rainwater pipe 310 is used to discharge the water flowing in the water purification chamber 300. The filter wall 400 is detachably installed between the sedimentation chamber 200 and the water purification chamber 300. The filter wall 400 is used to intercept the silt and sand in the sewage in the sedimentation chamber 200.

[0034] like Figure 1 and Figure 2 As shown, the environmentally friendly rainwater inlet consists of a well body 100, a sedimentation chamber 200, a water purification chamber 300, and a filter wall 400. The open end of the well body 100 is covered with several grates 110. The sedimentation chamber 200 is located within the well body 100 and is perpendicularly aligned with the grates 110. The water purification chamber 300 is connected to the sedimentation chamber 200 and contains a rainwater pipe 310 that communicates with the municipal drainage system. The filter wall 400 is detachably installed between the sedimentation chamber 200 and the water purification chamber 300. Rainwater first enters the sedimentation chamber 200 through several grates 110, where large suspended particles settle naturally under gravity. The water then flows through the filter wall 400, whose porous structure effectively intercepts fine sediment, preventing it from entering the purification chamber 300. The purified rainwater then enters the purification chamber 300 and is discharged into the municipal drainage system through the rainwater pipe 310. Thus, through multi-stage filtration via grates 110, sedimentation chamber 200, and filter wall 400, sediment and suspended solids in the rainwater are effectively reduced, lowering the risk of blockage in the municipal drainage system. Furthermore, the detachable design of the filter wall 400 simplifies maintenance, improves cleaning efficiency, extends the service life of the pipe network, and reduces operating costs.

[0035] In some specific embodiments of this utility model, the bottom elevation of the water purification chamber 300 is higher than the bottom elevation of the grit settling chamber 200. For example... Figure 2 and Figure 3As shown, the bottom of the purification chamber 300 is higher than the bottom of the grit chamber 200. This height difference creates a water level difference during rainwater flow, promoting natural water flow and sedimentation. Specifically, when rainwater enters the grit chamber 200, large particles of silt settle at the lower bottom due to gravity, while the relatively cleaner upper water flows towards the purification chamber 300 due to the water level difference. This optimizes sedimentation efficiency, reduces the likelihood of silt being carried into the purification chamber 300 by the water flow, and thus improves the overall filtration effect. Furthermore, the concentrated sedimentation in the grit chamber 200 facilitates cleaning. During maintenance, only the grit chamber 200 needs to be cleaned, rather than the purification chamber 300, thus reducing long-term maintenance costs.

[0036] In some specific embodiments of this utility model, the filter wall 400 includes a plurality of filter bricks 410, all of which are detachably connected to the well body 100. The plurality of filter bricks 410 are disposed between the sedimentation chamber 200 and the water purification chamber 300, and are stacked sequentially in the vertical direction.

[0037] like Figure 2 and Figure 4 As shown, the filter wall 400 is composed of multiple filter bricks 410, which are stacked vertically between the grit chamber 200 and the purification chamber 300. It should be noted that each filter brick 410 is a porous filtration structure capable of intercepting sediment and suspended solids of different particle sizes. When rainwater flows from the grit chamber 200 to the purification chamber 300, the water flows through different layers of filter bricks 410. Larger particles are first intercepted by the bottom filter bricks 410, while finer suspended solids are gradually filtered in the upper filter bricks 410, thus reducing the risk of clogging of the filter wall 400. In addition, since the filter bricks 410 can be disassembled individually, the entire filter wall 400 does not need to be removed when cleaning or replacing them. During maintenance, the filter bricks 410 can be removed first, that is, the permeable concrete brick strips can be disassembled one by one, and mud, sand and other debris can be removed from the rainwater connection pipe opening. At the same time, enough space can be created for maintenance personnel to put in the pipeline CCTV inspection equipment to inspect the rainwater connection pipe, thereby improving the convenience of maintenance.

[0038] In some specific embodiments of this utility model, a limiting groove 320 is provided on the walls on opposite sides of the water purification chamber 300. The limiting groove 320 is vertically arranged and corresponds to the width of the filter wall 400. The filter wall 400 is movably disposed in the limiting groove 320 to separate the water purification chamber 300 and the grit chamber 200.

[0039] like Figure 4 and Figure 5As shown, the front and rear walls of the water purification chamber 300 are provided with limiting grooves 320 that match the width of the filter wall 400. The limiting grooves 320 extend vertically, allowing the filter wall 400 to be movably embedded within them, effectively separating the water purification chamber 300 and the sedimentation chamber 200. When the filter wall 400 needs cleaning due to sediment buildup, it can be lifted upwards along the limiting grooves 320 or removed entirely, avoiding damage to the overall structure of the rainwater inlet. Furthermore, partially damaged filter walls 400 can be replaced individually without rebuilding the entire rainwater inlet structure, thus extending the service life of the facility and ensuring both high-efficiency filtration and practicality and economy.

[0040] In some specific embodiments of this utility model, a baffle plate 500 is also included. The baffle plate 500 is vertically installed on the top wall of the well body 100 and extends downward from the top wall of the well body. The baffle plate 500 is located on one side of the filter wall 400 and in the sedimentation chamber 200. The baffle plate 500 is used to guide the water flow from the sedimentation chamber 200 to the clean water chamber 300 to avoid short-circuiting or turbulence affecting the sedimentation effect.

[0041] like Figure 2 As shown, a baffle plate 500 is vertically installed on the top wall of the well body 100. The baffle plate 500 is located inside the sedimentation chamber 200 and on one side of the filter wall 400, thus preventing rainwater and its carried mud and sand impurities from splashing directly into the rainwater inlet connection pipe and guiding the flow direction of water in the sedimentation chamber 200. Specifically, when rainwater enters the sedimentation chamber 200 from the grate 110, it is blocked by the baffle plate 500 and forced to flow downward or around it, extending the hydraulic path. This guiding effect not only increases the contact time between the water flow and the bottom of the sedimentation chamber 200, promoting the natural settling of mud and sand, but also prevents high-speed water flow from directly impacting the filter wall 400, avoiding stirring up the settled mud and sand again.

[0042] In some specific embodiments of this utility model, a weir plate 600 is also included. The weir plate 600 is vertically disposed on the wall of the well body 100. The weir plate 600 is located between the filter wall 400 and the debris barrier 500. The top height of the weir plate 600 is lower than the top height of the debris barrier 500. The weir plate 600 is used to intercept scum and light debris on the water surface.

[0043] like Figure 2As shown, a vertically installed weir plate 600 is located inside the well body 100, adjacent to the filter wall 400. The weir plate 600 is situated between the debris barrier 500 and the filter wall 400, with its top height lower than the debris barrier 500. When water containing scum flows through the debris barrier 500 and encounters the lower-height weir plate 600, the surface floating matter accumulates on the water-facing side of the weir plate 600 due to physical obstruction, while the middle and lower layers of water pass smoothly through the space below the weir plate 600. This creates a multi-stage treatment space, which not only extends the residence time of floating matter in the grit chamber 200, facilitating subsequent cleaning, but also prevents scum from directly contacting the filter wall 400 and causing blockage. Simultaneously, the height difference between the weir plate 600 and the debris barrier 500 ensures that, under heavy rain conditions, excess rainwater can overflow through the top of the weir plate 600, maintaining the system's drainage capacity and significantly improving the operational reliability of the drainage system.

[0044] In some specific embodiments of this utility model, the weir plate 600 and the debris barrier plate 500 have overlapping areas in the vertical direction, thereby further constructing a tortuous water flow channel, which not only ensures the controllable passage of water flow, but also creates a relatively stable sedimentation environment.

[0045] In some specific embodiments of this utility model, the bottom of the settling chamber 200 has an inclined portion 210, which is located at the end of the settling chamber 200 away from the clean water chamber 300. The inclined portion 210 is inclined towards the clean water chamber 300, and is configured to prevent gravel from accumulating in the horizontal section at the bottom of the well body 100. Figure 2 As shown, the inclined section 210 is inclined towards the end near the water purification chamber 300. When rainwater containing sand and gravel flows in, the heavier particles will slide and accumulate along the inclined surface to the lowest point under the action of gravity, so that the sediment will automatically accumulate in the designated area, which greatly improves the convenience of dredging operations.

[0046] In some specific embodiments of this utility model, each grate 110 is provided with a filter bucket 111 at its bottom. The opening end of the filter bucket 111 corresponds to the size of the corresponding grate 110. The filter bucket 111 is used for preliminary filtration of large-sized debris in the water flow. Figure 1 As shown, a filter bucket 111 of matching size is configured below each grate 110, thus forming a double-layer interception system with the grate 110. When rainwater carrying debris passes through the gaps of the grate 110, it will immediately enter the secondary screening space of the filter bucket 111, realizing three-dimensional interception of larger debris in surface runoff.

[0047] In some specific embodiments of this utility model, four cast iron grates 110 with filter buckets 111 are symmetrically arranged on the top of the well body 100. The grate 110 corresponds to the water inlet area of ​​the sedimentation chamber 200. The sedimentation chamber 200 is kept horizontal on the side near the clean water chamber 300, and an inclined part 210 is provided at the far end to form an inclined bottom plate. A rainwater pipe 310 is pre-embedded in the rear wall of the clean water chamber 300, and a limiting groove 320 is preset on the front and rear side walls. A detachable filter wall 400 composed of three stackable filter bricks 410 is installed in the clean water chamber 300. The filter wall 400 can be flexibly disassembled and assembled through the limiting groove 320. A debris baffle 500 is provided on the water-facing side of the filter wall 400. The debris baffle 500 extends downward from the top wall of the well body 100. A weir plate 600 is provided between the filter wall 400 and the debris baffle 500. The two plates overlap vertically to form a scum interception area. Through multi-stage filtration of grate 110, grit chamber 200 and filter wall 400, the silt and suspended solids in rainwater are effectively reduced, lowering the risk of blockage in the municipal drainage system. At the same time, the detachable design of filter wall 400 simplifies the maintenance process, improves cleaning efficiency, and thus extends the service life of the pipeline network and reduces operation and maintenance costs.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
