Description

Technical Field

[0001] This invention relates to the field of building rainwater harvesting, specifically to a multifunctional rainwater harvesting and recycling device for buildings. Background Technology

[0002] Building rainwater harvesting and recycling is an important water resource management strategy that has emerged under the global water crisis, rapid urbanization, increasing ecological and environmental pressures, and policy and regulatory impetus. It aims to transform rainwater from a burden into a resource, thereby achieving sustainable water resource utilization and ensuring urban ecological security.

[0003] Existing methods for recycling and utilizing rainwater from buildings suffer from significant problems of pre-contamination by runoff impurities and blockage at the collection end. Solid impurities such as atmospheric dust, weathered and flaking particles from building components, debris from exterior wall coatings, fallen leaves, and biological remains accumulate over long periods on building roofs, facades, eaves, and drainage ditches. When rainwater forms roof runoff, it flows along the building envelope, carrying a large amount of inorganic particles and organic debris. This debris flows directly into the rainwater collection tank through downpipes. These impurities enter the collection unit without being intercepted, easily causing siltation in the tank and blockage in the drainage pipes, significantly increasing the processing load on subsequent sedimentation and filtration units.

[0004] In summary, existing building rainwater harvesting systems are prone to siltation and blockage of drainage pipes due to particulate impurities carried on building walls, which significantly increases the processing load on subsequent sedimentation and filtration units. Summary of the Invention

[0005] Based on this, the purpose of this invention is to provide a multi-functional rainwater recycling device for buildings, in order to solve the technical problem that existing building rainwater recycling devices are prone to siltation in the tank and blockage of drainage pipes due to particulate impurities carried on building walls, which greatly increases the processing load of subsequent sedimentation and filtration units.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional rainwater utilization and recycling device for buildings, comprising a box, wherein a filter assembly and a discharge assembly are respectively arranged inside the box; The filter assembly includes a filter plate disposed within a housing, wherein the filter plate is vertically slidable within the housing, and a cam is disposed at the bottom of the filter plate within the housing, the cam being used to drive the filter plate to slide vertically. The discharge assembly includes a scraper disposed within the housing, wherein the scraper is horizontally slidable above the filter plate, and a discharge hole is provided on the housing, and a collection box is disposed on one side of the discharge hole.

[0007] By adopting the above technical solution, under normal filtration conditions, the top of the filter plate is located below the discharge hole, thus effectively filtering rainwater from the building. When the stepper motor drives the threaded rod to rotate, it drives the cam to rotate through the transmission component, lifting the filter plate itself. At this time, the filter plate is flush with the discharge hole, and the bottom of the scraper contacts the filter plate, making it easy to discharge the filtered impurities on the filter plate into the collection box on one side, ensuring the continuous and stable operation of rainwater filtration.

[0008] The present invention is further configured such that a fixing plate is fixedly installed at the bottom of the filter plate inside the box, and the fixing plate is provided with a series of insertion rods that cooperate with the filter plate.

[0009] Preferably, during the process of lifting and scraping away impurities, some impurity particles remain in the filter holes. When the filter plate resets, the filter holes are cleaned by the insert rod, thereby ensuring the stability of the filter and extending the overall cleaning cycle of the device.

[0010] The invention is further configured such that the outer diameter of the insertion rod is smaller than the inner diameter of the filter hole on the filter plate.

[0011] Preferably, in the filtering state, the insertion rod will not clog the filter holes on the filter plate, ensuring that the filter plate itself can perform filtering operations normally.

[0012] The present invention is further configured such that a stepper motor is provided on one side of the housing, and a threaded rod is connected to the output end of the stepper motor, the threaded rod being used to drive the scraper to slide laterally.

[0013] Preferably, by starting a stepper motor, the threaded rod at the output end is rotated, thereby driving the scraper inside the box to slide laterally and scrape away impurities.

[0014] The present invention is further configured such that the output end of the stepper motor is provided with a transmission mechanism, wherein a full gear is connected to the other end of the transmission mechanism, a residual gear is meshed on one side of the full gear on the housing, and a rotating shaft is connected to one end of the residual gear through the housing, wherein the rotating shaft is used to drive the cam to rotate.

[0015] Preferably, when the stepper motor starts, its output end drives the transmission mechanism to rotate, which in turn drives the full gear to rotate. Through meshing with the residual gear, the rotating shaft inside the housing rotates by a certain angle, thereby causing the cam to rotate by a certain angle and lift the filter plate itself upward. When the scraper is reset, the stepper motor drives the transmission mechanism to reverse, and the cam also reverses to drive the filter plate to reset.

[0016] The present invention is further configured such that a drain pipe is provided at the bottom of one side of the box, and a control switch is provided on the drain pipe.

[0017] Preferably, the drainage pipe facilitates the direct discharge of rainwater filtered inside the container, making it easier for staff to collect it uniformly.

[0018] The present invention is further configured such that the transmission mechanism includes a driving disc, a transmission belt and a driven disc, the driving disc and the driven disc are connected by the transmission belt, the output end of the stepper motor is connected to the driving disc, and one end of the driven disc is connected to a full gear.

[0019] Preferably, the stepper motor drives the active disk to rotate, and the drive belt drives the driven disk to rotate, thereby driving the full gear on the outer wall of the housing to rotate.

[0020] The present invention is further configured such that a flexible protective sleeve is provided at the bottom of the scraper, and the flexible protective sleeve itself is detachable from the scraper.

[0021] Preferably, the flexible protective sleeve prevents jamming between the scraper and the filter plate during the sliding process, further improving the removal effect of impurity particles on the filter plate.

[0022] The present invention is further configured such that the scraper and the threaded rod are threadedly connected, and the two ends of the scraper are provided with limit mechanisms at the threaded rod.

[0023] Preferably, the threaded connection facilitates the lateral sliding of the scraper as the threaded rod rotates, and the setting of the limiting mechanism prevents the scraper from rotating on its own along with the threaded rod, further improving the stability of the scraper sliding.

[0024] In summary, the present invention has the following main beneficial effects: 1. This invention features a filter plate that slides vertically within the housing and a scraper that slides horizontally on the filter plate. In normal filtration mode, the top of the filter plate is positioned below the discharge hole, thus effectively filtering rainwater from the building. When the stepper motor drives the threaded rod to rotate, it drives the cam to rotate through the transmission assembly, lifting the filter plate itself. At this point, the filter plate is flush with the discharge hole, and the bottom of the scraper contacts the filter plate, facilitating the discharge of impurities filtered on the filter plate into a collection box on one side, ensuring continuous and stable rainwater filtration operations. 2. This invention features a fixed plate inside the housing, on which a rod is mounted to cooperate with the filter plate. Under normal conditions, since the outer diameter of the rod is smaller than the aperture of the filter plate itself, it does not affect the overall filtration and drainage operation. Furthermore, during the process of the filter plate lifting and scraping away impurities, some impurity particles remain in the filter holes. When the filter plate resets, the rod will remove impurities from the filter holes, thereby ensuring the stability of the filtration process and extending the overall cleaning cycle of the device.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of the present invention will now be described.

[0029] Example 1: Please refer to Figures 1-7The invention relates to a multi-functional rainwater recycling device for buildings, comprising a housing 1, a drain pipe 2, a filter plate 3, an adjustment component, a cleaning component, and a collection box 7. The filter plate 3 is installed inside the housing 1 and can slide vertically within the housing 1. When rainwater is introduced into the housing 1, a discharge hole 10 is provided on the housing 1, and a collection box 7 is located on one side of the discharge hole 10. When filtering, the top of the filter plate 3 is below the discharge hole 10, which can stably trap solid impurities in the rainwater, achieving efficient filtration and drainage, while preventing rainwater from being discharged into the collection box 7 through the discharge hole 10. A transmission mechanism 15 is also provided at the output end of a stepper motor 4, and a full gear 8 is connected to the other end of the transmission mechanism 15. A residual gear 9 is meshed on one side of the full gear 8 on the housing 1, and a rotating shaft 12 is connected to one end of the residual gear 9 through the housing 1. The rotating shaft 12 is used to drive a cam 14 to rotate. When the stepper motor 4 starts, its output drives the transmission mechanism 15 to rotate, which in turn drives the full gear 8 to rotate. Through meshing with the residual gear 9, the rotating shaft 12 inside the housing 1 rotates by a certain angle. This causes the cam 14 to rotate by a certain angle, lifting the filter plate 3 upwards so that the filter plate 3 is flush with the discharge hole 10. The top of the filter plate 3 contacts the bottom of the scraper 6. At this time, the scraper 6 slides to one side under the action of the stepper motor 4, which facilitates the discharge of the filtered impurities on the filter plate 3 into the collection box 7 on one side, ensuring the continuous and stable operation of rainwater filtration. Subsequently, a drain pipe 2 is provided at the bottom of one side of the housing 1. The drain pipe 2 is equipped with a control switch. Under the action of the drain pipe 2, the filtered rainwater inside the housing 1 can be directly discharged for unified collection by the staff.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A stepper motor 4 is installed on one side of the housing 1. A threaded rod 5 is connected to the output end of the stepper motor 4. The threaded rod 5 is used to drive the scraper 6 to slide laterally. By starting the stepper motor 4, the threaded rod 5 at the output end is rotated, thereby driving the scraper 6 inside the housing 1 to slide laterally and scrape away impurities. A flexible protective sleeve is provided at the bottom of the scraper 6. The flexible protective sleeve itself is detachable from the scraper. The flexible protective sleeve is designed to prevent jamming between the scraper 6 and the filter plate 3 during the sliding process, thereby further improving the removal effect of impurity particles on the filter plate 3.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 2The transmission mechanism 15 includes a driving disc, a transmission belt, and a driven disc. The driving disc and the driven disc are connected by the transmission belt. The driving disc is connected to the output end of the stepper motor 4, and one end of the driven disc is connected to the full gear 8. Under the action of the stepper motor 4, the driving disc can be driven to rotate. Under the action of the transmission belt, the driven disc can be driven to rotate, thereby driving the full gear 8 on the outer wall of the housing 1 to rotate.

[0032] Example 2: Please refer to Figure 6 The illustrated multi-functional rainwater recycling device for buildings has an overall structure similar to that of Embodiment 1. A fixing plate 11 is fixedly installed at the bottom of the filter plate 3 inside the housing 1. The fixing plate 11 has a series of insert rods 13 that cooperate with the filter plate 3. During the process of the filter plate 3 lifting and scraping away impurities, some impurity particles remain in the filter holes. When the filter plate 3 subsequently resets, the insert rods 13 remove impurities from the filter holes, thus ensuring the stability of the filtration process and extending the overall cleaning cycle of the device. Furthermore, the outer diameter of the insert rods 13 is smaller than the inner diameter of the filter holes on the filter plate 3, so during filtration, the insert rods 13 will not clog the filter holes on the filter plate, ensuring that the filter plate 3 can perform its filtration operation normally.

[0033] In practical operation, this invention works as follows: Construction wastewater is guided to the top of the housing 1, allowing rainwater to drain into the housing 1. A filter plate 3 is installed inside the housing 1, with a discharge hole 10 on one side. Under normal conditions, the top of the filter plate 3 is below the discharge hole 10, effectively trapping solid impurities in the rainwater and achieving efficient filtration and drainage. This also prevents rainwater from draining into the collection box 7 on one side through the discharge hole 10. Operators periodically activate a stepper motor 4 on one side of the housing 1. The stepper motor 4, in conjunction with a transmission assembly, causes the rotating shaft 12 to rotate the cam 14 at the bottom of the filter plate 3 at a certain angle. The cam 14 then lifts the filter plate 3, bringing it flush with the discharge hole 10. The top of the filter plate 3 contacts the bottom of the scraper 6. The output of the stepper motor 4 drives the threaded rod 5 to rotate, causing the scraper 6 to drain the fixed impurities on the filter plate 3 into the collection box on one side, ensuring continuous and stable rainwater filtration.
