Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an integrated construction control method for roof rainwater harvesting and drainage. Background Technology

[0002] Roof rainwater harvesting and drainage is a crucial component of building water supply and drainage systems. It needs to both achieve rapid rainwater discharge to prevent water accumulation and collect and utilize rainwater to practice environmental protection principles. Existing roof rainwater treatment equipment mostly has only one function of collection or drainage, which has many shortcomings that make it difficult to coordinate and fails to meet the requirements of efficient and environmentally friendly use.

[0003] Traditional roof rainwater systems generally suffer from the following problems: First, the collection and drainage functions are separated, requiring separate piping, which is complex, space-consuming, and costly. Second, they lack effective backflow prevention structures, making it easy for rainwater to backflow onto the roof or into the pipes when the storage tank is full, affecting safety. Third, the filter components are prone to clogging, and the intercepted impurities require regular manual cleaning, which is cumbersome and costly to maintain. Fourth, installation and fixing are inconvenient, relying heavily on welding or numerous bolts, resulting in poor flexibility in adapting to different roof structures. Fifth, incomplete cleaning of impurities can lead to bacterial growth or pipe blockage over time, affecting rainwater collection quality and drainage efficiency. These problems severely restrict the overall performance of roof rainwater systems and urgently require targeted improvements. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated construction control method for roof rainwater harvesting and drainage.

[0005] The technical solution adopted by this invention to solve its technical problem is: A construction control method for integrated rainwater harvesting and drainage of roofs includes the following steps: S1. Lay collection and drainage pipes at the designed drainage locations on the roof according to the designed slope; S2. Connect and lay the drainage pipe at the lower end of the collection drain pipe. Open a sewage trough on the drainage pipe and install a filter plate inside the drainage pipe according to the design angle, while ensuring that the inclined surface of the filter plate is opposite to the sewage trough. S3. An anti-backflow structure is installed inside the drainage pipe, including two support frames that are fixedly connected to each other on the inner wall of the drainage pipe. A circular floating block is provided between the two support frames. A sensing plate is fixedly connected to the upper surface of the circular floating block. A track rod is fixedly connected to the upper surface of the sensing plate. The outer surface of the track rod is slidably connected to the upper support frame. A sensor that is compatible with the sensing plate is provided on the bottom surface of the upper support frame. S4. Install a self-flushing structure on the outer wall of the drainage pipe and at the location of the sewage trough for closing or opening the sewage trough; install a water storage tank on the ground and connect the bottom end of the drainage pipe to the water storage tank; S5. When the water level in the reservoir rises to the preset height, the circular floating block floats up with the water level, pushing the sensor plate to move up along the guide direction of the track rod. When the sensor plate contacts the sensor on the bottom surface of the support frame, it triggers the self-flushing structure, which in turn opens the drain channel, allowing excess rainwater to drain out and preventing backflow into the roof or pipes.

[0006] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the self-flushing structure includes a track clip fixedly connected to the outer surface of the drain pipe. The track clip is provided along the vertical sides and bottom of the drain trough. The side of the track clip has a track groove, and the inside of the track groove is provided with a sealing gasket.

[0007] Preferably, the self-flushing structure further includes an electric telescopic rod fixedly connected to the outer surface of the drain pipe, and a transmission block is fixedly connected to the movable end of the electric telescopic rod.

[0008] Preferably, an arc-shaped clamping plate is fixedly connected to the side of the transmission block, and the arc-shaped clamping plate is slidably and sealingly connected to the inner wall of the track groove.

[0009] Preferably, the other end of the drainage pipe is rotatably connected to a fixing ring, and the inner wall of the fixing ring is provided with an arc-shaped magnetic block.

[0010] Preferably, a semi-circular support plate is fitted onto the outer surface of the collection and drainage pipe, and a fixing anchor rod is inserted into the inside of the semi-circular support plate.

[0011] Preferably, a magnetic absorbing piece corresponding to the arc-shaped magnetic absorbing block is provided on the bottom surface of one end of the collection drain pipe, and the cross-sectional shape of the collection drain pipe is semi-circular.

[0012] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: 1. This invention integrates rainwater collection, filtration, backflow prevention, and drainage through the integrated design of drainage pipes and collection drainage pipes. It eliminates the need for separate installation of multiple sets of pipes, simplifies the construction process, reduces installation costs, minimizes space occupation, and is adaptable to different building roof structures.

[0013] 2. With the help of the anti-backflow linkage structure, the circular floating block monitors the water level of the water storage tank in real time. When the water level is full, it automatically triggers the electric telescopic rod to switch the rainwater to be discharged from the sewage channel, thus avoiding backflow. Compared with traditional manual monitoring, it responds faster, is safer to use, and ensures the stable operation of the roof and equipment.

[0014] 3. The combination of the filter plate, the arc-shaped clamp, and the drain trough enables self-washing of impurities, eliminating the need for manual cleaning. Impurities intercepted by the filter plate accumulate on one side of the arc-shaped clamp. After the arc-shaped clamp moves, rainwater impacts the impurities and discharges them from the drain trough, improving cleaning efficiency, preventing filter component blockage, and reducing maintenance costs.

[0015] 4. Quick-install components adapt to different installation scenarios. The semi-circular bracket and fixed anchor rod ensure a stable fixation of the collection and drainage pipe. The magnetic structure quickly connects the drainage pipe and the collection and drainage pipe. The installation process does not require complicated tools and can be completed by a single person. The sealing gasket enhances the sealing of the connection and prevents water leakage. The versatility and convenience are significantly improved. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0019] like Figures 1 to 5 As shown in the figure, this embodiment provides a construction control method for integrated rainwater harvesting and drainage of roofs, including the following steps: S1. Lay collection and drainage pipes 2 at the designed drainage locations on the roof according to the designed slope; S2. Connect and lay drainage pipe 1 at the lower end of collection drainage pipe 2. Open sewage trough 6 on drainage pipe 1 and install filter plate 7 in drainage pipe 1 according to the design angle, while ensuring that the inclined surface of filter plate 7 is opposite to sewage trough 6. S3. An anti-backflow structure is installed inside the drainage pipe 1, including two support frames 10 fixedly connected to each other on the inner wall of the drainage pipe 1. A circular floating block 11 is provided between the two support frames 10. A sensing plate 12 is fixedly connected to the upper surface of the circular floating block 11. A track rod 13 is fixedly connected to the upper surface of the sensing plate 12. The outer surface of the track rod 13 is slidably connected to the upper support frame 10. A sensor adapted to the sensing plate 12 is provided on the bottom surface of the upper support frame 10. S4. Install a self-flushing structure on the outer wall of the drainage pipe 1 and at the location of the sewage trough 6 for closing or opening the sewage trough 6; install a water storage tank 5 on the ground and connect the bottom end of the drainage pipe 1 to the water storage tank 5; S5. When the water level in the reservoir 5 rises to the preset height, the circular floating block 11 floats up with the water level, pushing the sensor 12 to move up along the guide direction of the track rod 13. When the sensor 12 contacts the sensor on the bottom surface of the support frame 10, it triggers the self-flushing structure, which in turn opens the channel of the sewage trough 6, and excess rainwater is discharged from the sewage trough 6 to prevent backflow into the roof or pipes.

[0020] In practice, the drainage pipe 1 serves as the core flow guide. The sewage trough 6 on the outer surface is used to drain excess rainwater and wash away impurities on the filter plate 7 when the water is full. The filter plate 7, which is fixed inside, is set at an angle to intercept solid impurities in the rainwater and prevent them from entering the water storage tank and causing pollution or blockage.

[0021] The support frame 10 is fixed to the inner wall of the drainage pipe 1. The preferred installation position is on the lower side of the filter plate 7. It provides support and guidance for the circular floating block 11 and the track rod 13, ensuring that the circular floating block 11 moves smoothly up and down. The sensor and the sensing plate 12 cooperate precisely to realize the reliable transmission of water level signals.

[0022] The drainage pipe 1 can be made of PVC-U environmentally friendly pipe material, with a sewage trough 6 opened on the outer surface; the filter plate 7 is made of stainless steel and is fixed inside the drainage pipe 1 at an angle of 15° to ensure that impurities accumulate naturally; the circular floating block 11 is made of closed-cell foam material and is covered with a waterproof coating.

[0023] The support frame 10 is made of stainless steel angle steel and is fixed to the inner wall of the drainage pipe 1 at a spacing of 150mm; the track rod 13 is fixed to the upper surface of the sensor plate 12 and slides with the guide hole of the upper support frame 10 with a clearance of 0.1-0.2mm; the sensor is fixed to the bottom surface of the upper support frame 10 by bolts, with a vertical distance of 5mm from the sensor plate 12 to ensure accurate signal triggering.

[0024] The sensor 12 can have a built-in magnet, and the sensor uses a magnetic proximity switch. When the water tank 5 is full, the circular floating block 11 drives the sensor 12 to float up and approach the sensor, thereby triggering the full water signal.

[0025] The self-flushing structure includes a track clip 8 fixedly connected to the outer surface of the drain pipe 1. The track clip 8 is set along the vertical sides and bottom of the drain trough 6. The track clip 8 has a track groove 9 on its side and a sealing gasket is set inside the track groove 9.

[0026] The self-flushing structure also includes an electric telescopic rod 16 fixedly connected to the outer surface of the drain pipe 1, and a transmission block 15 fixedly connected to the movable end of the electric telescopic rod 16.

[0027] An arc-shaped clamping plate 14 is fixedly connected to the side of the transmission block 15, and the arc-shaped clamping plate 14 is slidably and sealingly connected to the inner wall of the track groove 9.

[0028] The filter plate 7, the arc-shaped clamping plate 14, and the drain trough 6 work together to form a self-cleaning structure for impurities. The filter plate 7 is tilted so that impurities accumulate on one side of the arc-shaped clamping plate 14. The electric telescopic rod 16 drives the arc-shaped clamping plate 14 to move, opening the drain trough 6. The impact force of rainwater washes the impurities out of the drain trough 6, thus achieving self-cleaning.

[0029] The electric telescopic rod 16 is waterproof, with a stroke of 50mm and a thrust of 100N. It is fixed to the outer surface of the drainage pipe 1 by a clamp. The transmission short block 15 is welded to the telescopic end of the electric telescopic rod 16. The arc of the arc-shaped plate 14 is adapted to the drainage pipe 1 and is fixed to the transmission short block 15 by bolts. It is embedded in the track slot 9. The track slot 9 is 12mm wide and 10mm deep. A rubber sealing gasket is pasted inside the track slot 9.

[0030] The other end of the drainage pipe 1 is rotatably connected to a fixing ring 17, and the inner wall of the fixing ring 17 is provided with an arc-shaped magnetic block.

[0031] A semi-circular support plate 3 is fitted onto the outer surface of the collection and drainage pipe 2, and a fixed anchor rod 4 is inserted into the inside of the semi-circular support plate 3.

[0032] A magnetic plate corresponding to the arc-shaped magnetic block is provided on the bottom surface of one end of the collection drain pipe 2, and the cross-sectional shape of the collection drain pipe 2 is semi-circular.

[0033] The semi-circular support plate 3, the fixed anchor rod 4, and the magnetic structure constitute the quick-installation components. The semi-circular support plate 3 supports the collection and drainage pipe 2, and the fixed anchor rod 4 is inserted into the roof structure to achieve rigid fixation. The fixing ring 17 and the collection and drainage pipe 2 are attracted and matched by the magnetic block and the magnetic plate for quick docking and installation. The sealing gasket in the track slot 9 enhances the sealing of the connection.

[0034] The semi-circular support plate 3 is made of ABS material with pre-drilled anchor holes inside; the fixed anchor rod 4 is made of hot-dip galvanized round steel, which is suitable for fixing different roof bases; the fixing ring 17 is rotatably connected to the drainage pipe 1, and the inner wall is pasted with an arc-shaped neodymium iron boron magnetic block with a magnetic strength of 10N. A magnetic sheet is pasted on the bottom surface of one end of the collection drainage pipe 2 to ensure tight adsorption.

[0035] The entire assembly is completed. The bottom end of the drainage pipe 1 is connected to the water storage tank 5, and the connection is sealed with sealant. The collection drainage pipe 2 is fitted into the semi-circular support plate 3 and fixed to the preset position on the roof by the fixed anchor rod 4. The collection drainage pipe 2 is pushed to connect with the fixing ring 17, and the magnetic block and magnetic plate are attracted and fixed, completing the overall assembly.

[0036] The principles of use in the embodiments of this invention include: Rainwater collection and filtration: Rainwater from the roof flows into the collection drain pipe 2, enters the drainage pipe 1 through the magnetic connection, and when the rainwater flows through the filter plate 7, solid impurities (such as leaves and pebbles) are intercepted. The filtered rainwater flows into the water storage tank 5 along the drainage pipe 1 for storage, thus realizing rainwater collection and utilization.

[0037] Anti-backflow linkage: When the water level in the water storage tank 5 rises to the preset height, the circular floating block 11 floats up with the water level, pushing the sensor 12 to move up along the guide direction of the track rod 13. When the sensor 12 contacts the sensor on the bottom surface of the support frame 10, it triggers the electric telescopic rod 16 to retract, driving the transmission short block 15 and the arc-shaped card plate 14 to move up along the track slot 9, opening the sewage trough 6 channel, and excess rainwater is discharged from the sewage trough 6 to prevent backflow into the roof or pipes.

[0038] Self-cleaning of impurities: Impurities intercepted by the filter plate 7 accumulate on one side of the arc-shaped card plate 14 due to its tilted setting. After the arc-shaped card plate 14 moves upward, the drain channel 6 opens, and the flowing rainwater generates an impact, flushing the accumulated impurities out of the drain channel 6, realizing the self-cleaning of the filter components and avoiding blockage. After the water level in the water storage tank 5 drops, the circular floating block 11 falls back, the sensing plate 12 separates from the sensor, the electric telescopic rod 16 extends, the arc-shaped card plate 14 resets, the drain channel 6 closes, and the rainwater collection state is restored.

[0039] Installation and maintenance: During installation, first fix the collection and drainage pipe 2 with the semi-circular bracket 3 and the fixed anchor rod 4, and then quickly connect the drainage pipe 1 and the collection and drainage pipe 2 with the magnetic structure. The sealing gasket ensures that there is no water leakage at the connection. During daily maintenance, regularly check the firmness of the magnetic connection and the operation status of the electric telescopic rod 16. If the filter plate 7 is stubbornly blocked, the arc-shaped card plate 14 can be opened for manual cleaning, which is convenient to operate.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
