Description

Technical Field

[0001] This invention relates to rainwater harvesting and treatment technology, specifically to a rainwater harvesting and reuse system for building roofs based on sponge city principles. Background Technology

[0002] In recent years, due to climate change and weakening environmental carrying capacity, my country's urban water ecosystems have faced two extremes: severe urban flooding, making stormwater management a safety hazard affecting urban development; and severe water shortages in most cities, resulting in a serious lack of water resources. This has led to a series of problems, including water ecosystem deterioration, water scarcity, water pollution, and a lack of water security. With socio-economic development and the increasing frequency of urban meteorological disasters, the demands on urban drainage engineering are rising.

[0003] Chinese invention patent CN219863727U discloses an automatic rainwater harvesting system for existing building roofs. This system employs a rainwater separation valve technology to automatically collect both dirty and clean rainwater from the roof, enabling multi-purpose use of rainwater and improving its efficiency. It can be installed close to the building walls; for existing roof drainage systems, only the length of the existing downpipes needs to be changed, and the downpipe ends need to be installed in a debris filter box. This system does not use any electrical control components, making it safe and reliable.

[0004] In existing rainwater storage systems, even after initial filtration, fine suspended solids gradually accumulate at the bottom of the storage tank, forming sludge. This accumulation can lead to fermentation and unpleasant odors, affecting the quality of the stored water and occupying valuable volume. Furthermore, the filter screens are easily clogged by leaves, mud, and other impurities, significantly reducing water flow capacity and causing rainwater overflow losses. Frequent manual cleaning and maintenance are also required, resulting in low automation and high maintenance costs. Therefore, a rainwater harvesting and reuse system for building roofs based on sponge city principles has been developed. Summary of the Invention

[0024] By regularly cleaning the bottom of the storage tank, the sediment at the bottom of the tank is removed, reducing water pollution and ensuring that the collected water is cleaner and suitable for reuse. This avoids the decrease in water storage capacity caused by sediment occupying usable space, while also ensuring smooth water flow, reducing water flow resistance caused by dirt blockage, and improving overall flow efficiency.

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.

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Example: Please refer to Figure 1 - Figure 9 A rainwater harvesting and reuse system for building roofs based on sponge city includes a main body 1. A support column 11 is snapped onto the outer surface of the main body 1, a docking cylinder 12 is fixedly installed at the upper end of the main body 1, and a support rod 13 is fixedly installed on the inner wall of the main body 1.

[0040] In this design, the support column 11 is used to support and limit the main body 1, thereby ensuring that the main body 1 is in a stable state. The support rod 13 is located in the middle of the inner cavity of the main body 1, and a piston is provided at the lower end of its outer surface to seal the main body 1 and facilitate the cleaning of any residual impurities inside.

[0041] Furthermore, the protective component 2, which is assembled on the inner wall of the docking cylinder 12, is used to clean the impurities accumulated at the end of the collection tube; wherein, the protective component 2 includes a conical cylinder 21 that is snapped into the inner wall of the docking cylinder 12, a flow guide ring 211 is fixedly provided at the upper end of the conical cylinder 21, and a filter plate 212 is snapped into the inner wall of the conical cylinder 21.

[0042] In this embodiment, the upper end of the drainage ring 211 is inclined and tilted towards the middle, thereby causing rainwater to concentrate in the middle of the conical cylinder 21.

[0043] The rainwater after screening is filtered a second time through the filter plate 212, which further reduces its internal impurities.

[0044] Furthermore, a snap-fit ​​ring 22 is snapped onto the inner wall of the conical cylinder 21, and a rotating plate 23 is rotatably mounted on the inner wall of the snap-fit ​​ring 22. Multiple sets of arc-shaped plates 231 are evenly fixed at the upper end of the rotating plate 23, and an arc-shaped groove 232 is opened at the end of the arc-shaped plate 231.

[0045] Specifically, the outer surface of the snap ring 22 is provided with bolts and other components that have a fixing function. The snap ring 22 is locked to the inner wall of the conical cylinder 21 by bolts. At the same time, the inner wall of the snap ring 22 is provided with threaded grooves, which are rotated and fixed to the inner wall of the snap ring 22 by rotating plate 23.

[0046] Furthermore, a driving component 24 is fixedly installed at the middle position of the upper end of the rotating plate 23, and a driving plate 241 is fixedly installed at the output end of the driving component 24. Multiple sets of connecting blocks 242 are uniformly fixedly installed on the outer surface of the driving plate 241.

[0047] Specifically, the driving component 24 is a device with power output, such as a motor, and is connected to an external control device. When the driving component 24 is started, it drives the driving plate 241, which is fixedly set at its output end, to rotate. Since the connecting block 242 is fixedly set on the driving plate 241, it drives the connecting block 242 to rotate synchronously.

[0048] Furthermore, an adjusting block 25 is rotatably provided on one side of the end of the connecting block 242, and a scraper 251 is fixedly provided on the upper end of the adjusting block 25.

[0049] Specifically, when the connecting block 242 rotates, it synchronously drives the adjusting block 25, which is rotatably mounted on one side of it, to rotate. The adjusting block 25 is a component with telescopic function. When the adjusting block 25 moves, it drives the scraper 251 to move on the outer surface of the sieve plate 27.

[0050] Furthermore, an adjusting rod 26 is rotatably provided on the inner wall of the end of the connecting block 242. The end of the adjusting rod 26 is fixedly connected to the end of the adjusting block 25, and the end of the adjusting rod 26 away from the connecting block 242 is slidably connected to the inner wall of the arc groove 232.

[0051] Specifically, by sliding the adjusting rod 26 to the inner wall of the arc groove 232, the end of the adjusting rod 26 moves along the inner wall of the arc groove 232 when the connecting block 242 rotates, thereby causing the adjusting block 25, which is fixedly connected to the adjusting rod 26, to rotate.

[0052] Furthermore, a sieve plate 27 is snapped onto the inner wall of the conical cylinder 21. Multiple sets of guide grooves 271 are evenly provided at the end of the sieve plate 27, and the inner wall of the guide grooves 271 is slidably connected to the outer surface of the adjusting block 25. A collection groove 28 is provided at the end of the sieve plate 27 near the edge.

[0053] Specifically, the guide groove 271 limits the adjustment block 25 to ensure the stability of the adjustment block 25 and the scraper 251, and the collection groove 28 is opened to collect the impurities after screening.

[0054] When rainwater is guided into the conical cylinder 21 by the diversion ring 211, it is first initially filtered by the filter plate 212, and larger impurities such as leaves and branches are intercepted. Then the rainwater falls to the sieve plate 27, which filters the rainwater again, intercepting smaller particles of impurities. The drive unit 24 is activated, which drives the drive plate 241 to rotate. The drive plate 241 drives the adjusting block 25 to rotate together with it through the connecting block 242.

[0055] Since the adjusting block 25 is slidably connected to the guide groove 271 on the sieve plate 27, the guide groove 271 guides the rotation of the adjusting block 25; at the same time, one end of the adjusting rod 26 slides in the arc groove 232, and the trajectory of the arc groove 232 causes the adjusting rod 26 to rotate on its own axis while revolving with the adjusting block 25, thereby driving the adjusting block 25 and the scraper 251 to adjust their angles.

[0056] During rotation, the scraper 251 can scrape off impurities on the upper surface of the sieve plate 27 to prevent impurities from clogging the sieve holes of the sieve plate 27. The scraped impurities are pushed to the edge of the sieve plate 27 under the action of centrifugal force and eventually fall into the collection tank 28, realizing the centralized collection of impurities for subsequent cleaning.

[0057] Furthermore, the cleaning component 3 is assembled on the outer surface of the support rod 13 and is used to discharge the sludge deposited at the bottom of the inner cavity of the main body 1. The cleaning component 3 includes a fixed plate 31 that is slidably connected to the outer surface of the support rod 13. Multiple sets of movable grooves 32 are evenly opened at the upper end of the fixed plate 31, and movable blocks 33 are slidably arranged on the inner wall of the movable grooves 32.

[0058] Specifically, the movable block 33 is limited by the movable groove 32 opened on the fixed plate 31, so that when the movable block 33 is moved by force, it can only slide along the trajectory of the movable groove 32, thus preventing the movable block 33 from deviating during the movement.

[0059] Furthermore, a movable rod 34 is fixedly provided on one side of the movable block 33, and the end of the movable rod 34 passes through and extends to the outside of the fixed plate 31. At the same time, a cleaning plate 341 is snapped onto the end of the movable rod 34.

[0060] Specifically, when the movable block 33 slides in the movable groove 32, it will drive the movable rod 34 fixedly connected to it to move synchronously. The movable rod 34 will push the cleaning plate 341 to scrape at the bottom of the inner cavity of the main body 1, thereby pushing the sludge deposited at the bottom towards the middle position.

[0061] The lower end of the inner wall of the main body 1 is conical, so that when it moves downward, the movable rod 34 slowly moves towards the middle by squeezing and pushes the accumulated impurities to the middle position.

[0062] Furthermore, a disc 35 is rotatably provided on the inner wall of the fixed plate 31, and a guide groove 351 corresponding to the movable block 33 is opened at the end of the disc 35. The inner wall of the guide groove 351 is slidably connected to the outer surface of the upper end of the movable block 33.

[0063] Specifically, when the disc 35 rotates, it rotates in conjunction with the guide groove 351 at its end, thereby driving the movable block 33, which is slidably disposed on the inner wall of the guide groove 351, to move along the inner wall of the movable groove 32.

[0064] The end of the disc 35 may be equipped with a device with power output, such as a motor, to drive the disc 35 to rotate, thereby driving the limiting cylinder 36 to rotate.

[0065] Furthermore, a limiting cylinder 36 is fixedly provided on the inner wall of the disc 35, and a turntable 361 is fixedly provided at both ends of the limiting cylinder 36, and the ends of the turntable 361 are rotatably connected to the two ends of the fixing plate 31.

[0066] Specifically, when the disc 35 rotates, it drives the turntables 361 fixed at both ends to rotate. At the same time, the ends of the turntables 361 are fitted and slidably disposed at the ends of the fixed plate 31, thereby ensuring that the turntables 361 remain stable as a whole when rotating.

[0067] Furthermore, multiple sets of protective rods 363 are slidably arranged on the outer surface of the turntable 361, and a cleaning ring 362 is fixedly arranged at the end of the protective rod 363. The outer surface of the cleaning ring 362 is in contact with the inner wall of the main body 1.

[0068] Specifically, the outer surface of the protective rod 363 is provided with a spring to support the cleaning ring 362, thereby ensuring that the cleaning ring 362 is tightly attached to the inner wall of the main body 1.

[0069] Furthermore, a positioning block 37 is rotatably provided on the outer surface of the support rod 13, and the end of the positioning block 37 is engaged with the end of the turntable 361. At the same time, multiple sets of airbags 38 are uniformly fixed on the outer surface of the positioning block 37.

[0070] Specifically, the positioning block 37 is used to assist in positioning and supporting the rotation of the turntable 361, ensuring the stability of the turntable 361's rotation; the airbag 38 can automatically adjust its volume according to the water pressure when the water level inside the main body 1 changes, thereby providing a certain buffering and adjustment effect on the position of the fixing plate 31, so that the cleaning component 3 can maintain a good cleaning effect under different water level conditions.

[0071] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0072] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
