[0002] Green roofs, also known as roof gardens or eco-roofs, refer to an ecological technology that covers part or all of a building's roof with vegetation and growing substrate. Traditional green roof systems, especially in the field of modular planting boxes, have some shortcomings or deficiencies: Traditional green roofs rely primarily on soil substrates and plant roots for simple infiltration and absorption, offering limited purification capabilities for fine suspended particles and organic pollutants carried in rainwater, thus failing to achieve high-quality water resource recycling. Furthermore, the filtration system of these purification devices inevitably becomes clogged over long-term operation, requiring frequent manual cleaning or replacement of filter cartridges and removal of sludge, resulting in heavy maintenance work. This is especially problematic on large-area roofs where maintenance is difficult, and the uneven roof surface often leads to uneven planting modules that are simply placed side by side, hindering centralized connection and drainage, resulting in localized water accumulation and low adaptability.

The outlet of the first water pump is connected to an external water storage tank via a pipeline; The other end of the drain pipe is connected to the inside of the filter pipe, and the collection hopper is located directly below the filter pipe.

[0006] Furthermore, the impurity removal unit includes a cleaning pipe fixed inside the treatment box, a plurality of cleaning nozzles equally spaced on the cleaning pipe, a second water pump installed on the outer wall of the treatment box, a water supply pipe with one end connected to the liquid outlet of the second water pump and the other end connected to the cleaning pipe, an impact pipe connected to the water supply pipe, an impact nozzle installed on the impact pipe, and a turbine fixedly sleeved on the upper outer wall of the filter tube and corresponding to the impact nozzle. The inlet of the second water pump is connected to an external water storage tank via a pipe; Several of the cleaning nozzles are perpendicular to the outer wall of the filter tube; The second water pump is driven, and the water flows through the impact nozzle to impact the blades of the turbine.

[0007] Furthermore, the water conveying section includes several connecting pipes that are respectively connected to the bottom of several purification tanks, several sealing rings that are respectively fitted onto both ends of several connecting pipes, and several guide grooves that are respectively opened in the bottom of several purification tanks and correspond to several connecting pipes.

[0008] Furthermore, the irrigation unit includes several supports fixed to the upper ends of several planting frames, several irrigation pipes fixed in the several supports, and several micro-spray nozzles installed at equal intervals on the several irrigation pipes. The two adjacent irrigation pipes are detachably connected by a pipe joint; The water inlet pipe and the second sealing head are respectively installed on the two irrigation pipes at both ends of the irrigation section, and the other end of the water inlet pipe is connected to the external water storage tank.

[0011] Compared with the prior art, the embodiments of this utility model have the following beneficial effects: This green roof embedded purification device, through the cooperation of a substrate layer, a permeable layer, a non-woven filter pad, and a filter screen in the planting frame, allows for preliminary physical and biological filtration of rainwater while plants are planted on the substrate layer. The rainwater filtered by several planting frames is then transported to the treatment unit with the help of the water conveyance unit. In the treatment unit, it undergoes a second stage of precision filtration through a rotating filter tube, and the initial rainwater is discharged, effectively removing finer pollutants and ensuring the quality of the purified rainwater. This allows the rainwater to be recycled and used to irrigate the plants in the planting frames, facilitating the recycling of purified water and achieving high-quality water resource recovery. This green roof embedded purification device, through its impurity removal section, allows high-pressure water to be vertically flushed against the outer wall of the filter tubes when the filtration efficiency decreases after a period of use. In conjunction with the impact nozzles, the same stream of high-pressure water impacts the turbine blades, driving the turbine to rotate the filter tubes automatically. This ensures that the filter tubes are flushed while rotating, resulting in thorough cleaning without any blind spots. Impurities are flushed into the collection hopper and can be periodically discharged through the drain valve, making cleaning very convenient. This greatly reduces long-term maintenance costs and the frequency of manual intervention, ensuring the long-term stable and efficient operation of the purification device. This green roof embedded purification device allows for independent height adjustment and leveling of each purification box via support screws at the four corners, perfectly adapting to the roof slope. This ensures that the assembled purification boxes maintain the same height and remain level, guaranteeing tight contact. Combined with several connecting parts, the device enables quick, stable, and level installation on roofs with varying slopes and uneven surfaces. It also ensures accurate connection of the connecting pipes on the purification boxes, ensuring stable connectivity and synchronous drainage, preventing localized water accumulation, and guaranteeing the overall stability and reliability of the device.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] like Figure 1-8 As shown, a green roof embedded purification device includes: a purification box 1, a plurality of purification boxes 1 are fitted together, and a planting frame 2 is slidably inserted into the upper part of the inner wall of each of the purification boxes 1. Water conveying section 3 is provided on a plurality of purification boxes 1, and drain pipe 4 and first sealing head 5 are respectively provided at both ends of the water conveying section 3; Processing unit 6, which is connected to the other end of the drain pipe 4, is used to further filter the rainwater passing through the purification box 1; The irrigation section 7 is installed on a plurality of the purification boxes 1, and the two ends of the irrigation section 7 are respectively provided with a water inlet pipe 8 and a second sealing head 9; Impurity removal unit 10 is installed inside the processing unit 6 and is used to clean up the impurities accumulated inside the processing unit 6; Support parts 11, a plurality of support parts 11 are respectively disposed at the lower end of a plurality of purification boxes 1, for supporting the plurality of purification boxes 1 respectively; Connecting parts 12, a plurality of the connecting parts 12 are respectively installed on a plurality of the purification boxes 1, for connecting the plurality of purification boxes 1 to each other; The planting frame 2 is provided with a substrate layer 27, a water-permeable layer 28, a non-woven fabric filter pad 29, and a filter screen 30 from top to bottom inside; When rainwater falls onto the roof, some of it is intercepted and absorbed by the plants in the planting frames 2, and then seeps downwards. The rainwater passes sequentially through the substrate layer 27, the permeable layer 28, the non-woven filter pad 29, and the filter screen 30 within the planting frames 2, effectively separating and removing most suspended solids, particulate matter, and some pollutants. If a plant in a single planting frame 2 malfunctions, the planting frame 2 can be quickly removed from the corresponding purification box 1 for replacement. The pre-purified water flows into the bottom of the purification box 1, and the bottoms of several purification boxes 1 are interconnected through the water conveying part 3, thus allowing the several purification boxes 1 to collect water. The collected water can be gathered into the drain pipe 4 and discharged to the treatment unit 6. The treatment unit 6 discharges the rainwater at the beginning of the rainfall, while the subsequent water is filtered by the filter pipe 14 and stored in the treatment tank 13. It is then pumped by the first water pump 18 through the water collection pipe 19 into an external water storage tank for later use. The filtered impurities settle into the collection hopper 15 and are discharged through the sewage pipe 16. This achieves double filtration of rainwater, resulting in high purification efficiency, ensuring the quality of the effluent, and guaranteeing the usability of the purified rainwater. When the filter pipe 14 needs cleaning, the second water pump 22 of the impurity removal unit 10 is started, and the high-pressure water flows through several cleaning sections. The nozzle 21 sprays vertically onto the outer surface of the rotating filter tube 14, flushing away the clogging impurities. Simultaneously, another stream of water, through the impact nozzle 25, precisely sprays onto the turbine 26 mounted on the filter tube 14. The reaction force of the water flow drives the filter tube 14 to rotate automatically, ensuring thorough cleaning. The flushed impurities fall into the collection hopper 15, and the drain valve 17 can be opened periodically for centralized discharge, achieving automatic cleaning of the filter tube 14, effectively reducing manual intervention and ensuring maintenance efficiency. When irrigation is needed, purified water from the storage tank is pumped through the inlet pipe 8 into several irrigation pipes 35 of the irrigation section 7. Finally, the water is discharged through… The micro-spray nozzles 36 spray water evenly onto the plants in the form of atomization or fine rain, completing the closed-loop utilization of water resources. When several purification boxes 1 are installed on the roof, the height of the purification boxes 1 can be independently adjusted and leveled through the support part 11. This ensures that several purification boxes 1 are at the same height and remain flat on uneven or sloping roofs, ensuring the effective connection of the bottom connecting pipes 31 of several purification boxes 1. This guarantees the long-term stable and efficient operation of the purification device. At the same time, several connecting parts 12 tightly connect adjacent purification boxes 1 to form a stable whole, resisting wind loads and preventing displacement.

[0017] Optionally, the processing unit 6 includes a processing box 13 installed on the green roof, a filter tube 14 rotatably installed in the processing box 13 via bearings, a collection hopper 15 connected to the lower end of the processing box 13, a drain pipe 16 connected to the lower end of the collection hopper 15, a drain valve 17 installed on the drain pipe 16, and a first water pump 18 installed on the outer wall of the processing box 13, one end of which is connected to the liquid inlet of the first water pump 18, and the other end of which extends to a water collection pipe 19 at the bottom of the processing box 13. The outlet of the first water pump 18 is connected to an external water storage tank via a pipe; The other end of the drain pipe 4 is connected to the inside of the filter pipe 14, and the collection hopper 15 is located directly below the filter pipe 14; During use, rainwater enters the rotating filter tube 14 through the drain pipe 4. In the first few minutes of the initial rainfall, the drain valve 17 is open, allowing the high-concentration sewage at the beginning of the rainfall to be discharged directly through the drain pipe 16, thus avoiding affecting the filtration effect of subsequent rainwater. After a period of time, the drain valve 17 closes the drain pipe 16. After the water flows into the filter tube 14, it is filtered by the filter tube 14, and impurities are left inside the filter tube 14. Heavier impurities settle into the collection hopper 15 below under gravity. The design of the collection hopper 15 makes the sedimentation and collection of impurities very convenient, facilitating centralized cleaning and preventing large-area accumulation at the bottom of the treatment tank 13. The filtered impurities can then be periodically discharged through the drain valve 17 and the drain pipe 16. The filtered clean water accumulates inside the treatment tank 13 and is finally pumped by the first water pump 18 through the water collection pipe 19 into the external water storage tank for storage. The filter tube 14 provides a secondary physical barrier, which can remove finer pollutants and ensure the quality of the effluent.

[0018] Optionally, the impurity removal unit 10 includes a cleaning pipe 20 fixed inside the treatment box 13, a plurality of cleaning nozzles 21 evenly spaced on the cleaning pipe 20, a second water pump 22 installed on the outer wall of the treatment box 13, a water supply pipe 23 with one end connected to the liquid outlet of the second water pump 22 and the other end connected to the cleaning pipe 20, an impact pipe 24 connected to the water supply pipe 23, an impact nozzle 25 installed on the impact pipe 24, and a turbine 26 fixedly sleeved on the upper outer wall of the filter pipe 14 and corresponding to the impact nozzle 25. The inlet of the second water pump 22 is connected to an external water storage tank via a pipe; Several of the cleaning nozzles 21 are perpendicular to the outer wall of the filter tube 14; The second water pump 22 is driven, and the water flows through the impact nozzle 25 to impact the blades of the turbine 26; After the filter tube 14 has been used for a period of time, the second water pump 22 can be started. High-pressure water jets are sprayed vertically from the outside of the filter tube 14 through the cleaning pipe 20 and several cleaning nozzles 21 to flush away the impurities clogging the filter screen. At the same time, the same high-pressure water jets are precisely sprayed onto the blades of the turbine 26 through the impact pipe 24 and impact nozzles 25. The turbine 26 is driven to rotate by the impact force of the water flow, thereby driving the filter tube 14 to rotate automatically. The water pressure of the cleaning water is used as a power source, which has high energy utilization efficiency and simple and reliable structure. While the filter tube 14 is rotating, several cleaning nozzles 21 can complete the comprehensive rinsing of the filter tube 14, avoiding blind spots in cleaning and realizing fully automatic cleaning, which greatly reduces the workload and cost of later maintenance.

[0019] Optionally, the water conveying part 3 includes a plurality of connecting pipes 31 that are respectively connected to the bottom of a plurality of purification tanks 1, a plurality of sealing rings 32 that are respectively sleeved on both ends of the plurality of connecting pipes 31, and a plurality of guide grooves 33 that are respectively opened in the bottom of the plurality of purification tanks 1 and correspond to the plurality of connecting pipes 31. The drain pipe 4 and the first plug head are respectively installed on the two connecting pipes 31 at both ends of the water conveying part 3; When several purification boxes 1 are assembled, they are tightly connected to each other through several connecting parts 12, so that the connecting pipes 31 at the bottom of several purification boxes 1 are connected to each other, and the internal parts of multiple purification boxes 1 are connected in series to form a connected water storage space. The collected water from all purification boxes 1 is collected in one place and transported to the treatment unit 6 through the drain pipe 4. The sealing ring 32 between two adjacent connecting pipes 31 is squeezed to ensure that there is no water leakage at the joint between two adjacent connecting pipes 31. The guide groove 33 is designed to prevent water accumulation at the bottom of the box and ensure that all water can flow into the connecting pipe 31.

[0020] Optionally, the irrigation section 7 includes a plurality of supports 34 respectively fixed to the upper ends of a plurality of planting frames 2, a plurality of irrigation pipes 35 respectively fixed in the plurality of supports 34, and a plurality of micro-spray nozzles 36 respectively installed at equal intervals on the plurality of irrigation pipes 35. The two adjacent irrigation pipes 35 are detachably connected by a pipe joint 37. The water inlet pipe 8 and the second sealing head are respectively installed on the two irrigation pipes 35 at both ends of the irrigation section 7, and the other end of the water inlet pipe 8 is connected to the external water storage tank; When the plants in the planting frame 2 are dry due to lack of water, irrigation water enters from the inlet pipe 8 into several irrigation pipes 35 of the irrigation section 7 through the external water storage tank. It is then sprayed evenly and slowly onto the plants through several micro-sprinklers 36 to prevent the plants from drying out and dying. Compared with flood irrigation, micro-sprinkler irrigation can significantly reduce water evaporation and loss, resulting in significant water conservation. It can also increase air humidity, creating a microenvironment conducive to plant growth and promoting healthy plant growth. Furthermore, since adjacent irrigation pipes 35 are quickly connected through pipe joints 37, they match the modular design of the purification box 1, making it convenient to disassemble them simultaneously as the planting frame 2 is removed from the corresponding purification box 1.

[0021] Optionally, the support part 11 includes a plurality of bearing seats 38 fixed in a rectangular array at the lower end of the purification box 1, a plurality of support screws 39 respectively threaded to the plurality of bearing seats 38, and universal supports 40 respectively movably installed at the lower end of the plurality of support screws 39. By rotating several support screws 39, the height of the four corners of a single purification box 1 can be adjusted independently, thereby adjusting its levelness and overall height. This ensures that several purification boxes 1 can be at the same height and remain level on an uneven roof surface, facilitating the subsequent connection of several connecting parts 12 to complete the interconnection of several purification boxes 1. It also ensures that several connecting pipes 31 on each purification box 1 are accurately connected, ensuring the effective delivery of purified rainwater by the water supply part 3, avoiding local water accumulation. Furthermore, it allows the purification box 1 to be suspended, completely confining the plant roots inside the purification box 1, preventing them from contacting the roof waterproofing layer below, thus fundamentally eliminating the risk of root puncture. At the same time, the elevated space at the bottom of the purification box 1 forms an air circulation layer, which can effectively remove the water vapor generated by the evaporation of accumulated water, avoiding the problem of roof dampness.

[0022] Optionally, the connecting part 12 includes two connecting screws 41 symmetrically hinged to the outer wall of the purification box 1, two connecting seats 42 symmetrically fixed to the outer wall of the purification box 1, two connecting grooves 43 respectively opened on the connecting seats 42, two connecting nuts 44 respectively threaded to the two connecting screws 41, and two limiting plates 45 symmetrically fixed to the outer wall of the purification box 1. When the device is assembled on the roof, the connecting screws 41 of two adjacent purification boxes 1 are inserted into the connecting grooves 43 on the connecting seat 42 of the other, and then the connecting nuts 44 are tightened to tightly connect several dispersed purification boxes 1 together, ensuring the overall stability and anti-displacement ability, preventing them from falling apart under the interference of the external environment, ensuring the compression stability of the sealing rings 32 between two adjacent purification boxes 1, and avoiding water leakage at the contact position between two adjacent connecting pipes 31. Before assembly, one of the purification boxes 1 will be inserted between the two limiting plates 45 on the adjacent purification box 1 to ensure the quick positioning of several purification boxes 1. The hinged screw and limiting plate 45 design makes the alignment and tightening operation very quick and simple.
