Description

Technical Field

[0001] This invention relates to the field of municipal engineering drainage technology, and in particular to a honeycomb-type rainwater collection tank. Background Technology

[0002] Currently, rainwater storage and collection devices used at the end of municipal stormwater branch pipes and in small sites can be mainly divided into three categories: The first category is traditional cast-in-place concrete or brick-built fixed storage tanks, which are large-scale centralized facilities in the civil engineering category. They are formed by on-site formwork casting and brick masonry, equipped with inlets, overflow outlets, and sewage outlets. They rely on the cavity of the tank to store rainwater and are mostly used in large areas, main roads, and other scenarios with large catchment areas. The second category is conventional PP assembled rainwater collection modules, which use standardized polypropylene injection-molded single modules. They are assembled on-site and then buried underground. The outside is wrapped with impermeable geotextile. They rely on the cavity of the module to store water and are mostly used in underground spaces such as green belts and parks, mainly for large-area underground water storage. The third category is small fixed-size prefabricated rainwater tanks, which are mostly made of fiberglass or integrated injection molding. Their volume and external dimensions are fixed and they are directly buried and connected to the rainwater pipes. They are suitable for very small and scattered sites.

[0003] Traditional fixed stormwater storage tanks suffer from poor site adaptability and extremely high construction and maintenance costs. Traditional concrete stormwater storage tanks are rigid, fixed structures where volume, size, and shape are designed and molded in a single step, leaving no room for flexible adjustments. These structural defects directly limit their application: firstly, these tanks are large in size, require extensive excavation, and have stringent requirements on site area and foundation bearing capacity, making them suitable only for open sites. They are unsuitable for areas with narrow, irregular locations such as road corners, narrow gaps in old residential areas, and narrow green belts where stormwater branch pipes often end. The installation requirements are high, which can easily lead to problems such as site inability to carry out construction, damage to existing ground structures and greenery; on the other hand, the on-site pouring construction cycle is long, requires large construction equipment, and causes great interference to surrounding traffic and residents' lives during the construction process. Moreover, the pool is a rigid integrated structure that cannot be expanded, disassembled or moved later. Once the catchment area of ​​the area is adjusted or the pipeline network is renovated, the pool will be directly abandoned, with a zero reuse rate. At the same time, the concrete pool is prone to cracking and leakage, and the space for cleaning is small and extremely difficult after the silt and sand accumulate inside. The operation and maintenance costs throughout the entire life cycle remain high.

[0004] Conventional PP rainwater modules are standardized, universal water storage units with fixed individual structures and splicing methods. They can only be laid flat or stacked in large areas, lacking dedicated interfaces and layout designs for the ends of rainwater branch pipes. Their core flaws stem from their universal, large-capacity structural design: First, the overall size of the module assembly is too large, making it impossible to flexibly adjust the volume and shape for small, scattered sites at the ends of branch pipes. In small-capacity scenarios, splicing redundancy is high, wasting materials and space. Second, the module's internal structure is a dense, hollow support structure without independent drainage and flow guidance structures. Sediment and suspended solids in rainwater runoff easily accumulate in the module's cavity gaps, adhering tightly and difficult to clean. Long-term use significantly reduces the effective water storage capacity, and repairs require disassembling numerous surrounding modules after partial module damage, greatly increasing maintenance difficulty. Third, these modules are designed for large-area underground water storage and lack a miniaturized, compact layout design suitable for the ends of branch pipes. The fixed positions of the inlet, overflow, and drainage interfaces cannot match the varying pipe connection angles and elevations at the ends of branch pipes, resulting in poor installation adaptability.

[0005] Small, integrated prefabricated rainwater tanks are integrally injection molded or fiberglass-cured. Their volume, shape, and interface positions are all fixed parameters, leaving no room for combination or adjustment. The defects are entirely due to their integral, fixed structure: these tanks have a single size, making it impossible to accurately match the volume according to the site size, catchment area, and storage requirements. Either the volume is too large to fit on the site, or the volume is too small to meet the storage and peak shaving requirements. Moreover, the tank is a single integral structure, which cannot achieve multi-unit combination and linkage. It can only be used for a very few fixed-specification sites and cannot be adapted to complex and variable branch pipe end scenarios such as old urban areas and municipal branch roads, thus greatly limiting its application scope.

[0006] Existing stormwater storage facilities are all centralized or general-purpose designs, and their structures have not been optimized to address the core characteristics of stormwater branch pipe ends: "dispersed layout, small single-point catchment area, flexible storage capacity requirements, and proximity to the main pipe network." They generally suffer from poor interface compatibility, inability to freely combine and deform, non-adjustable volume, and high maintenance difficulty. As a result, it is difficult to achieve localized storage of stormwater runoff at the source, leading to a large amount of stormwater flowing directly into the main pipe network from the branch pipe ends. Problems such as excessive instantaneous flow, pipe network pressure overload, and localized road surface water accumulation still exist, failing to truly meet the refined management requirements of "infiltration, retention, storage, and drainage" for sponge cities. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a honeycomb-type rainwater harvesting tank. These shortcomings include: traditional concrete tanks being bulky and unsuitable for small, irregular sites; conventional PP modules being too large and lacking flexibility for fine-tuning; and small prefabricated tanks having fixed dimensions that are difficult to match with the scattered spaces at the ends of branch pipes. None of these existing facilities can flexibly adjust the size and layout of the tank according to the catchment area and storage requirements, easily leading to either excess volume waste or insufficient volume for peak shaving. Furthermore, the hollow internal structure of conventional PP modules lacks a dedicated sewage drainage design, making it difficult to clean after sediment accumulation. Traditional tanks and prefabricated tanks are integral structures, preventing future expansion and renovation, resulting in high maintenance costs. The fixed positions of the inlet and outlet ports cannot match the varying pipe diameters, elevations, and connection angles at the ends of branch pipes, easily leading to leakage and poor drainage. Traditional civil engineering requires large equipment and has a long construction period. Existing modules lack compact designs for small, scattered projects, resulting in an imbalance between construction flexibility and economy.

[0008] The objective of this invention is achieved as follows:

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0017] The filter assembly is located within a combination of two three-hole side plates, two closed side plates, and two double-hole side plates. When rainwater fills and flows into the three-hole side plates, closed side plates, and double-hole side plates, secondary filtration is performed.

[0018] As a preferred embodiment of the present invention, the upper ends of the two side plates are provided with an upper fixing plate and a lower fixing plate, and the upper fixing plate and the lower fixing plate are engaged and connected with the column.

[0019] In a preferred embodiment of the present invention, the upper fixed plate has a circular opening at its upper end, and the upper fixed plate has an upper cover plate at its upper end, the upper cover plate covering the circular opening.

[0020] In a preferred embodiment of the present invention, the sedimentation tank assembly includes an upper sedimentation tank, a lower sedimentation tank, a connecting rod B, a three-joint suction pipe, a filter screen, a stirring rod, and a connecting rod A. The upper and lower sedimentation tanks are fixedly positioned symmetrically. The filter screen is fixedly connected to the upper sedimentation tank. The three-joint suction pipe is located in the lower sedimentation tank, with the other end of the three-joint suction pipe penetrating the lower sedimentation tank and extending outward. The connecting rod B is located inside a side plate and rotatably connected to the filter screen. The stirring rod is fixedly connected to the circumferential surface of the connecting rod B and is located above the filter screen. The connecting rod A is located at the upper end of the connecting rod B and rotatably connected to the upper cover plate.

[0021] As a preferred embodiment of the present invention, the filter assembly includes a rigid filter element, filter cotton, and an outer frame, wherein multiple sets of filter cotton are provided, and the surface of the outer frame is fixed to the adjacent ends of a three-hole side plate, a closed side plate, and a two-hole side plate, respectively. The rigid filter element is located inside the outer frame, and multiple sets of filter cotton are fixedly connected to the surface of the rigid filter element, and all sets of filter cotton are located inside the outer frame.

[0022] As a preferred embodiment of the present invention, the lower sedimentation tank is provided with an inclined plate, and the three-joint suction pipe is located on the lower inclined surface of the inclined plate.

[0023] In a preferred embodiment of the present invention, the lower end of the connecting rod A is fixedly connected to a threaded rod, and the upper end of the connecting rod B is provided with a threaded hole, wherein the threaded rod is threadedly connected to the threaded hole.

[0024] In a preferred embodiment of the present invention, a rotating wheel is fixedly connected to the upper end of the connecting rod A; the rotating wheel is configured as an interface structure for receiving external torque and driving the connecting rod A to rotate.

[0025] As a preferred embodiment of the present invention, the upper and lower ends of the upper cover plate are provided with limiting rubber rings, and the two limiting rubber rings are sleeved on the circumferential surface of the connecting rod A.

[0026] As a preferred embodiment of the present invention, one of the closed side plates is provided with a water outlet pipe on one side, and the water outlet pipe is connected to the interior of the combination of two three-hole side plates, two closed side plates and two double-hole side plates.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. Adopting a honeycomb modular design, the six side panels, three-hole side panels, closed side panels, and double-hole side panels are connected by columns. The overall shape has no fixed size restrictions. The number of modules can be increased or decreased and the combination can be adjusted according to the actual space of small and irregular sites such as the end of rainwater branch pipes, road corners, gaps in old communities, and narrow green belts. At the same time, the interlocking positioning structure of the upper and lower fixed plates and columns ensures the overall stability after assembly.

[0029] 2. The sedimentation tank assembly includes an upper sedimentation tank, a lower sedimentation tank, and a filter screen to achieve gravity settling and initial interception of large particles. The lower sedimentation tank is equipped with an inclined plate, and a three-joint suction pipe is located on the lower inclined surface of the inclined plate. The inclined surface guides the flow to concentrate and collect the sediment, which can be quickly pumped out by external suction equipment, achieving "dig-free" maintenance. At the same time, connecting rod A drives connecting rod B to rotate, so that the stirring rod continuously agitates the water above the filter screen, actively preventing the filter holes from clogging and extending the cleaning cycle of the filter assembly. The filter assembly adopts a combination structure of hard filter core and multiple sets of filter cotton for secondary fine filtration of fine suspended solids.

[0030] 3. All components are assembled using a snap-fit ​​connection method, eliminating the need for cast-in-place concrete curing. This achieves "factory prefabrication and rapid on-site assembly," with installation cycles measured in hours or days. The absence of large hoisting equipment significantly reduces road occupancy time and disruption to surrounding traffic and residents. The modular units utilize lightweight and durable materials, ensuring high transportation efficiency and suitability for long-distance transport. Compared to traditional concrete pools, it eliminates the need for expensive reinforced concrete and large-scale earthwork excavation. Compared to conventional PP modules, it features an independent drainage structure and an active anti-clogging mechanism, significantly reducing the frequency and cost of subsequent maintenance.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1-13 The present invention provides the following technical solutions:

[0048] A honeycomb-type rainwater harvesting tank includes:

[0049] Six side panels 1;

[0050] Water inlet pipe 5, which is fixed to one of the side plates 1;

[0051] Multiple columns 21, each column 21 is located on one side of each side plate 1, and the column 21 and the side plate 1 are connected by a snap-fit ​​connection;

[0052] Two three-hole side plates 2001, two closed side plates 2002 and two double-hole side plates 2003, each of the three-hole side plates 2001, closed side plates 2002 and double-hole side plates 2003 is engaged with the column 21 and is hexagonal in shape, with one side of one of the three-hole side plates 2001 being attached to the side plate 1;

[0053] Two lower fixing plates 23 are located at the upper and lower ends of the three-hole side plate 2001, the closed side plate 2002 and the double-hole side plate 2003 respectively, and both lower fixing plates 23 are engaged with the column 21.

[0054] The sedimentation tank assembly is located inside the two side plates 1. When rainwater passes through the inlet pipe 5, it will fill the sedimentation tank assembly and filter impurities in the rainwater through the sedimentation tank assembly.

[0055] The filter assembly is located in the combination of two three-hole side plates 2001, two closed side plates 2002 and two double-hole side plates 2003. When rainwater fills and flows into the three-hole side plates 2001, closed side plates 2002 and double-hole side plates 2003, secondary filtration is performed.

[0056] The sedimentation tank assembly includes an upper sedimentation tank 11, a lower sedimentation tank 12, a connecting rod B10, a three-joint suction pipe 13, a filter screen 15, a stirring rod 14, and a connecting rod A9. The upper sedimentation tank 11 and the lower sedimentation tank 12 are fixedly fixedly arranged vertically. The filter screen 15 is fixedly connected to the upper sedimentation tank 11. The three-joint suction pipe 13 is located in the lower sedimentation tank 12. The other end of the three-joint suction pipe 13 passes through the lower sedimentation tank 12 and extends outward. The connecting rod B10 is located in the side plate 1 and is rotatably connected to the filter screen 15. The stirring rod 14 is fixedly connected to the circumferential surface of the connecting rod B10 and is located on the upper side of the filter screen 15. The connecting rod A9 is located at the upper end of the connecting rod B10 and is rotatably connected to the upper cover plate 3.

[0057] The filter assembly includes a rigid filter element 6, filter cotton 7, and an outer frame 8. Multiple sets of filter cotton 7 are provided. The surface of the outer frame 8 is fixed to the adjacent ends of the three-hole side plate 2001, the closed side plate 2002, and the double-hole side plate 2003, respectively. The rigid filter element 6 is located inside the outer frame 8. Multiple filter cotton 7 are fixedly connected to the surface of the rigid filter element 6, and all multiple filter cotton 7 are located inside the outer frame 8.

[0058] In a specific embodiment of the present invention, the filter cotton 7 in this device is composed of PP cotton and glass fiber cotton. When assembling the honeycomb rainwater collection tank, the six side plates 1 are first initially arranged according to a hexagonal outline. Then, multiple columns 21 are placed on one side of each side plate 1, and each column 21 is engaged with its corresponding side plate 1 to form a stable support frame. When constructing the internal honeycomb structure, the operator sequentially engages two three-hole side plates 2001, two closed side plates 2002, and two two-hole side plates 2003 with the columns 21, making the overall structure hexagonal. The shape is such that one side of one of the three-hole side plates 2001 is in close contact with the aforementioned side plate 1. To fix the upper and lower end faces, two lower fixing plates 23 are respectively installed at the upper and lower ends of the three-hole side plate 2001, the closed side plate 2002, and the double-hole side plate 2003, and both lower fixing plates 23 are engaged with the column 21. Thus, an internal filtration chamber composed of the three-hole side plate 2001, the closed side plate 2002, and the double-hole side plate 2003 is formed, as well as an external sedimentation chamber enclosed by the side plates 1. After rainwater enters the equipment through the inlet pipe 5, it first enters the two... The sedimentation tank assembly area, formed by side plates 1, is continuously filled with rainwater. During this process, large particles of impurities in the rainwater naturally settle within the sedimentation tank assembly, achieving initial impurity filtration. After reaching a certain level within the sedimentation tank assembly, the rainwater continues to flow into the internal cavity composed of two three-hole side plates 2001, two closed side plates 2002, and two double-hole side plates 2003. When the internal cavity is full, the rainwater passes through the filter assembly for secondary fine filtration. Specifically, the rainwater first comes into contact with the hard filter element 6 and the filter cotton 7, where the filter... The cotton 7 is equipped with multiple sets to effectively intercept tiny suspended solids, thereby obtaining cleaner collected water. In summary, this honeycomb rainwater collection tank achieves a modular honeycomb structure through the combination and interlocking of side plate 1, column 21, three-hole side plate 2001, closed side plate 2002, double-hole side plate 2003 and lower fixed plate 23. The overall assembly is convenient and the structure is strong. The internally integrated sedimentation tank component and filter component form a two-stage filtration system: first, sedimentation and separation are carried out using the upper sedimentation tank 11, lower sedimentation tank 12 and filter screen 15, and then anti-clogging and sewage discharge are achieved through the stirring rod 14 and the three-joint suction pipe 13.Subsequently, a hard filter element 6 and multiple sets of filter cotton 7 are used for fine filtration, significantly improving rainwater purification efficiency. All parts are assembled using snap-fit ​​or adhesive methods, facilitating disassembly and maintenance and reducing long-term operating costs. Existing rainwater collection tanks often use a single filtration method, such as only setting up a sedimentation zone or only setting up a simple filter screen, which easily leads to the accumulation and clogging of impurities, resulting in limited filtration effect and difficulty in cleaning. At the same time, traditional collection tanks are mostly integrally cast or welded structures, which are bulky and extremely inconvenient to transport and install on site. Once a component is damaged, the entire tank often needs to be replaced. In contrast, this solution adopts a honeycomb modular design, which uses multiple side plates 1 and columns 21 to form a honeycomb modular structure. The hexagonal unit design is not only compact and high-strength, but also allows for flexible combination and expansion to adapt to different site requirements. More importantly, this solution integrates a two-stage purification system: a sedimentation tank assembly and a filtration assembly. The sedimentation tank assembly removes large particles through an upper sedimentation tank 11, a lower sedimentation tank 12, and a filter screen 15, with an active anti-clogging mechanism implemented by a stirring rod 14. The filtration assembly then uses a hard filter element 6 and multiple sets of filter cotton 7 for fine filtration, significantly improving the quality of the effluent. Furthermore, all parts are connected by snap-fit ​​or adhesive joints, facilitating individual disassembly, cleaning, or replacement, greatly reducing maintenance difficulty and life-cycle costs, and overcoming the shortcomings of existing technologies such as fixed structures, single filtration methods, and difficult maintenance.

[0059] Please refer to the details. Figures 1-8 The upper end of the side plate 1 is provided with an upper fixing plate 2 and a lower fixing plate 23, and the upper fixing plate 2 and the lower fixing plate 23 are engaged and connected to the column 21.

[0060] In this embodiment: the operator places the upper fixing plate 2 and the lower fixing plate 23 on the upper and lower ends of the side plate 1, respectively. At this time, the upper fixing plate 2 and the lower fixing plate 23 are engaged with the column 21 on one side of the side plate 1. In this way, the upper fixing plate 2 and the lower fixing plate 23 further lock the multiple side plates 1 and the column 21, thereby enhancing the stability of the entire outer structure of the collection pool.

[0061] Please refer to the details. Figure 8 The upper fixed plate 2 has a circular opening at its upper end, and the upper fixed plate 2 has an upper cover plate 3 at its upper end, which covers the circular opening.

[0062] In this embodiment: when it is necessary to seal the top of the collection pool, the operator opens a circular opening at the upper end of the upper fixing plate 2, and then places the upper cover plate 3 on the upper fixing plate 2 and makes the upper cover plate 3 completely cover the circular opening. In this way, the sealing of the inside of the collection pool is guaranteed, and an openable entrance is provided for subsequent maintenance and operation of internal components.

[0063] Please refer to the details. Figure 8An inclined plate 18 is provided in the lower sedimentation tank 12, and a three-joint suction pipe 13 is located on the lower inclined surface of the inclined plate 18.

[0064] In this embodiment: When the sedimentation tank assembly is performing sludge settling and discharge, the inclined plate 18 installed in the lower sedimentation tank 12 plays a role in guiding flow and collecting sludge. The three-joint suction pipe 13 is located on the lower inclined surface of the inclined plate 18, that is, the lowest side of the inclined plate 18. When the sludge slides down the inclined surface of the inclined plate 18, it will naturally collect in the area where the three-joint suction pipe 13 is located. At this time, the external suction equipment is started, and the three-joint suction pipe 13 can efficiently extract the sludge collected on the lower inclined surface of the inclined plate 18, reducing sludge residue.

[0065] Please refer to the details. Figure 8 The lower end of the connecting rod A9 is fixedly connected to a threaded rod 16, and the upper end of the connecting rod B10 is provided with a threaded hole 19, in which the threaded rod 16 is threadedly connected.

[0066] In this embodiment: when connecting rod A9 and connecting rod B10 need to be assembled into one unit, the operator aligns the threaded rod 16 at the lower end of connecting rod A9 with the threaded hole 19 at the upper end of connecting rod B10, and then rotates connecting rod A9 to screw the threaded rod 16 into the threaded hole 19, thus completing the threaded connection between the two. When it is necessary to disassemble or replace stirring rod 14, the connecting rod A9 is rotated in the opposite direction to allow the threaded rod 16 to exit from the threaded hole 19, achieving quick separation.

[0067] Please refer to the details. Figures 7-8 A rotating wheel 4 is fixedly connected to the upper end of the connecting rod A9; the rotating wheel 4 is configured as an interface structure for receiving external torque and driving the connecting rod A9 to rotate.

[0068] In this embodiment: when it is necessary to drive the stirring rod 14 to rotate to prevent the filter screen 15 from clogging, the operator or an external power source applies torque to the rotating wheel 4. The rotating wheel 4 is located at the upper end of the connecting rod A9 and serves as an interface structure to receive external torque. When the rotating wheel 4 rotates, it drives the connecting rod A9 to rotate, and then drives the connecting rod B10 and the stirring rod 14 to rotate together through the cooperation of the threaded rod 16 and the threaded hole 19. The operator can manually rotate the rotating wheel 4, or connect the output end of the power equipment such as the motor to the rotating wheel 4 to achieve automated drive.

[0069] Please refer to the details. Figure 8 The upper and lower ends of the upper cover plate 3 are provided with limiting rubber rings 17, and the two limiting rubber rings 17 are sleeved on the circumferential surface of the connecting rod A9.

[0070] In this embodiment: When the connecting rod A9 rotates within the upper cover plate 3, in order to ensure the stability and sealing of the rotation process, two limiting rubber rings 17 are respectively set at the upper and lower ends of the upper cover plate 3. Both limiting rubber rings 17 are fitted around the circumferential surface of the connecting rod A9. The upper limiting rubber ring 17 prevents the connecting rod A9 from moving downwards, and the lower limiting rubber ring 17 prevents the connecting rod A9 from moving upwards. At the same time, it seals the gap between the connecting rod A9 and the upper cover plate 3 to prevent external impurities from entering or internal rainwater from overflowing.

[0071] Please refer to the details. Figures 4-13 One of the closed side plates 2002 has a water outlet pipe 22 on one side, and the water outlet pipe 22 is connected to the interior of the combination of two three-hole side plates 2001, two closed side plates 2002 and two double-hole side plates 2003.

[0072] In this embodiment: the operator installs the water outlet pipe 22 on one side of one of the closed side plates 2002. The internal channel of the water outlet pipe 22 is connected to the internal cavity composed of two three-hole side plates 2001, two closed side plates 2002 and two double-hole side plates 2003. The rainwater after secondary filtration collects inside the assembly. When the liquid level reaches the inlet height of the water outlet pipe 22, the rainwater flows into the water outlet pipe 22 naturally and is guided to the external water storage container or the point of use. Since the water outlet pipe 22 is directly installed on the closed side plate 2002 and connected to the filtered clean water area, it ensures that the discharged rainwater has a high water quality, while avoiding additional openings in the load-bearing structure and maintaining the integrity of the side plate.

[0073] The workflow of this invention is as follows: After the installer completes the snap-fit ​​connection of all components, the six side plates 1 and multiple columns 21 form an external support frame. Two three-hole side plates 2001, two closed side plates 2002, and two double-hole side plates 2003 snap-fit ​​onto the columns 21 to form a hexagonal internal cavity. Two lower fixing plates 23 are located at the upper and lower ends of the assembly, respectively, and are snap-fitted and positioned with the columns 21. The sedimentation tank assembly is located within the space enclosed by the two side plates 1, and the filter assembly is located inside the assembly of the three-hole side plates 2001, closed side plates 2002, and double-hole side plates 2003. At this time, the entire collection tank is in a standby state. After rainwater enters the collection tank through the inlet pipe 5, it first flows into the sedimentation tank assembly area formed by the two side plates 1. This sedimentation tank assembly includes an upper sedimentation tank. The sedimentation tank assembly consists of tank 11, lower sedimentation tank 12, connecting rod B10, three-joint suction pipe 13, filter screen 15, stirring rod 14, and connecting rod A9. Rainwater continuously flows in, gradually filling the sedimentation tank assembly. During this process, rainwater first enters the upper sedimentation tank 11. The filter screen 15 initially intercepts the incoming water, blocking large suspended solids and impurities such as fallen leaves. The water continues to flow downwards into the lower sedimentation tank 12, where heavier sludge settles to the bottom under gravity. The three-joint suction pipe 13 is located inside the lower sedimentation tank 12, with its other end penetrating the lower sedimentation tank 12 and extending outwards for periodically discharging deposited sludge. To prevent the filter screen 15 from being clogged by impurities, the connecting rod B10 is located inside the side plate 1 and rotates within the filter screen 15. The stirring rod 14 is located on the circumferential surface of the connecting rod B10. Located above filter screen 15, it rotates with the rotation of connecting rod B10, continuously agitating the water above filter screen 15, causing impurities attached to the surface of filter screen 15 to detach and suspend, maintaining the permeability of filter screen 15. Connecting rod A9 is located above connecting rod B10 and rotates within the upper cover plate 3, transmitting external power to connecting rod B10. Through the action of the sedimentation tank assembly, large particles of impurities in rainwater are initially removed. When the water level in the sedimentation tank assembly continues to rise and exceeds the height of the water passage holes of the three-hole side plate 2001, the rainwater that has undergone preliminary sedimentation flows into the internal cavity composed of two three-hole side plates 2001, two closed side plates 2002, and two double-hole side plates 2003. This filter assembly includes a hard filter element 6, filter cotton 7, and an outer... The frame 8 contains multiple sets of filter cotton 7. When rainwater fills the internal cavity and flows through the filter assembly, the surface of the outer frame 8 is positioned relative to the adjacent ends of the three-hole side plate 2001, the closed side plate 2002, and the double-hole side plate 2003, forming a flow channel. The hard filter core 6 is located inside the outer frame 8, providing deep filtration support. Multiple sets of filter cotton 7 are located on the surface of the hard filter core 6 and are all located inside the outer frame 8. Rainwater passes through the first set of filter cotton 7, the hard filter core 6, and subsequent sets of filter cotton 7 in sequence. Tiny suspended solids, colloidal particles, and residual organic matter are intercepted layer by layer. The clean rainwater after secondary filtration collects at the bottom of the combined cavity. When the filtered clean water level reaches the inlet height of the outlet pipe 22, the rainwater naturally flows into the outlet pipe 22.The water is guided to an external water storage container or water point. The outlet pipe 22 is located on one side of one of the closed side plates 2002 and is connected to the interior of the combination of two three-hole side plates 2001, two closed side plates 2002 and two double-hole side plates 2003 to ensure that the water used is always clean water after two stages of filtration. When it is necessary to clean the sludge accumulated in the sedimentation tank assembly, the operator connects the external suction equipment to the outward extension end of the three-joint suction pipe 13 and starts the equipment to discharge the sludge at the bottom of the lower sedimentation tank 12. When it is necessary to clean the filter screen 15 more thoroughly or replace the filter cotton 7, the operator opens the upper cover plate 3, separates the connecting rod A9 from the upper end of the connecting rod B10, and then takes out the relevant parts in sequence for cleaning or replacement. When it is necessary to disassemble the entire filter assembly, the operator first releases the three-hole side plate 2001, closed side plate 2002 and double-hole side plate 2003 from the column 21, and then takes out the outer frame 8, hard filter element 6 and multiple sets of filter cotton 7 for maintenance. ,
