Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting and diversion technology, specifically a rainwater harvesting and diversion device for sponge cities. Background Technology

[0002] The significant increase in impermeable areas in cities has weakened the natural infiltration capacity of rainwater, exacerbating urban flooding and severely limiting the resource utilization of rainwater. The concept of "sponge cities" has emerged to address this, aiming to make cities resilient, like sponges, in adapting to environmental changes and responding to natural disasters caused by rainwater. Rainwater harvesting and diversion devices are a key component of sponge city construction. However, existing rainwater harvesting devices have several shortcomings. Some devices lack effective filtration systems, resulting in collected rainwater containing a large number of impurities of varying particle sizes and some harmful substances, severely impacting rainwater quality and making it difficult to use directly for subsequent applications such as greening irrigation and landscape water replenishment. Furthermore, some devices have poorly designed diversion structures, preventing the orderly convergence and centralized storage of collected rainwater, leading to low harvesting efficiency. Additionally, the installation and disassembly of filter components in existing devices are inconvenient, resulting in high maintenance costs and difficulties. Moreover, the lack of real-time monitoring methods for device operation makes it impossible to promptly detect problems such as rainwater collection blockage and effectively prevent rainwater storage tank overflow.

[0003] To address the aforementioned issues, a rainwater harvesting and diversion device for sponge cities is proposed here. Utility Model Content

Each of the first and second flow guide pipes 2 has a second flow guide pipe 9 fixedly connected to its middle bottom end. A second flow guide pipe 10 is fixedly connected to the bottom of each of the second flow guide pipes 9. A third flow guide pipe 11 is fixedly connected to the middle bottom end of each of the second flow guide pipes 10. The third flow guide pipe 11 is connected to the rainwater storage tank 5. Flow sensors 12 are fixedly installed inside each of the first flow guide pipes 2. A level sensor 20 is fixedly installed at the middle of the top of the inner wall of the rainwater storage tank 5. A sealed control box 21 is fixedly installed on one side of the top of the inner wall of the rainwater storage tank 5. A wireless signal transceiver module 22 and a control module 23 are fixedly installed at the bottom of the inner side of the sealed control box 21. The flow sensors 12, level sensors 20, and wireless signal transceiver module 22 are all connected to the control module. Block 23 is electrically connected. By setting the first filter screen 15, the second filter screen 16, and the third filter screen 17, rainwater is filtered in multiple stages, which can effectively remove impurities of different particle sizes and some harmful substances from the rainwater, improve the quality of collected rainwater, and provide a guarantee for the subsequent use of rainwater. Through the reasonable connection of the first guide pipe 2, the first collection pipe 3, the second guide pipe 9, the second collection pipe 10, and the third guide pipe 11, the rainwater collected by each rainwater collection seat 1 is orderly gathered and introduced into the rainwater storage tank 5, realizing efficient rainwater diversion and centralized storage. The design of the ring mounting seat 13 engaging with the fixing ring 14 and several connecting slots 18 engaging with several connecting blocks 19 respectively makes the installation and disassembly of the filter assembly easy. It is very convenient to clean or replace the filter screen regularly, reducing maintenance costs and work difficulty. Flow sensors 12 are installed in each first guide pipe 2 to monitor the amount of rainwater collected per unit time in each rainwater collection seat 1 in real time. Data analysis is used to determine whether the rainwater collection seat 1 is blocked, and a signal is sent to the client in a timely manner through the wireless signal transceiver module 22 to remind the management personnel to clean it, ensuring the collection efficiency of the device. The liquid level sensor 20 installed in the rainwater storage tank 5 can monitor the water level in real time to prevent rainwater from overflowing and ensure the safe operation of the device. The rainwater collection seat 1 adopts a funnel-shaped design, which increases the contact area with rainwater, enabling it to collect surface runoff rainwater more widely and quickly, improving rainwater collection efficiency.

[0020] In use, this embodiment of the application describes a device comprising several rainwater collection seats 1 and a rainwater storage tank 5. The rainwater collection seats 1 are evenly distributed in urban areas requiring rainwater collection, such as along roadsides and around squares. Each rainwater collection seat 1 has a fixed annular mounting base 13 at its inner center. The annular mounting base 13 has an annular structure, its size adapted to a fixing ring 14, providing a stable mounting foundation for the fixing ring 14. The tops of each of the several annular mounting bases 13 are engaged with a fixing ring 14. This engagement design makes the installation and removal of the fixing ring 14 very convenient. When maintenance or replacement of the filter assembly is required, the fixing ring 14 can be easily removed from the annular mounting base 13. Regarding the filter assembly, the several fixing rings 14... Each inner top is fixedly equipped with a first filter screen 15. The first filter screen 15 uses a filter material with a larger pore size, which can initially intercept larger particles and impurities in rainwater, such as leaves and stones, to prevent them from entering the subsequent pipes and causing blockages. A second filter screen 16 is fixedly equipped in the middle of the inner side of each of the several fixing rings 14. The second filter screen 16 has a smaller pore size than the first filter screen 15, which can further filter smaller particles and suspended solids in the rainwater, improving the cleanliness of the rainwater. A third filter screen 17 is fixedly equipped at the bottom of the inner side of each of the several fixing rings 14. The third filter screen 17 uses a fine filter screen, which can deeply filter the rainwater, removing tiny impurities and some harmful substances, ensuring high-quality collected rainwater. After collection, the rainwater needs to be diverted. Each water collection base 1 has a fixed connection to a first guide pipe 2 at its bottom. The first guide pipe 2 guides the rainwater collected by each rainwater collection base 1 downwards. A first collecting pipe 3 is fixedly connected to the bottom of several first guide pipes 2 located on the same side. The first collecting pipe 3 collects rainwater from multiple rainwater collection bases 1 on the same side. A second guide pipe 9 is fixedly connected to the middle of the bottom of several first collecting pipes 3. The second guide pipe 9 continues to transport the rainwater collected by the first collecting pipes 3 downwards. A second collecting pipe 10 is fixedly connected to the bottom of several second guide pipes 9. The second collecting pipe 10 further concentrates the rainwater. A third guide pipe 11 is fixedly connected to the middle of the bottom of the second collecting pipe 10. The third guide pipe 11 connects to the rainwater... The storage tanks 5 are connected, and the filtered rainwater is ultimately introduced into the rainwater storage tanks 5 for storage. In order to realize intelligent management of the device, flow sensors 12 are fixedly installed inside several first guide pipes 2. The flow sensors 12 can monitor the amount of rainwater collected per unit time of each rainwater collection seat 1 in real time. Under normal circumstances, the amount of rainwater collected by each rainwater collection seat 1 should be within a relatively stable range. If the flow sensor 12 of a certain rainwater collection seat 1 detects that the amount of rainwater collected per unit time is significantly lower than the normal value, it can be determined that the rainwater collection seat 1 may be blocked. For example, the first filter screen 15, the second filter screen 16, or the third filter screen 17 may be blocked by large impurities, or there may be foreign objects inside the first guide pipe 2 that obstruct the flow of rainwater.A liquid level sensor 20 is fixedly installed at the center of the top of the inner wall of the rainwater storage tank 5. The liquid level sensor 20 can monitor the water level in the rainwater storage tank 5 in real time. When the water level reaches the set upper limit, timely measures can be taken, such as stopping rainwater collection or starting the drainage device, to prevent rainwater from overflowing. A sealed control box 21 is fixedly installed on one side of the top of the inner wall of the rainwater storage tank 5. The sealed control box 21 has good sealing performance and can prevent rainwater from entering and damaging internal components. A wireless signal transceiver module 22 and a control module 23 are fixedly installed at the bottom of the inner side of the sealed control box 21. Several flow sensors 12, liquid level sensors 20, and wireless signal transceiver module 22 are all electrically connected to the control module 23. The control module 23 receives the data transmitted by the flow sensors 12 and liquid level sensors 20, processes and analyzes it. When it is determined that a rainwater collection seat 1 is blocked, the control module 23 sends a signal to the client, such as the administrator's mobile phone or computer, through the wireless signal transceiver module 22 to remind the administrator to clean the rainwater collection seat 1 in time to ensure the normal operation of the device.

[0021] Example 2: Please see Figure 1-6This utility model provides a rainwater collection and diversion device for sponge cities, including several rainwater collection seats 1 and rainwater storage tanks 5. Each rainwater collection seat 1 has an annular mounting base 13 fixedly installed in the middle of its inner side. Each annular mounting base 13 has a fixing ring 14 engaged at its top. Each fixing ring 14 has a first filter screen 15 fixedly installed at its top inner side. Each fixing ring 14 has a second filter screen 16 fixedly installed in the middle of its inner side. Each fixing ring 14 has a third filter screen 17 fixedly installed at its bottom inner side. Each rainwater collection seat 1 has a first diversion pipe 2 fixedly connected to its bottom. The bottoms of the several first diversion pipes 2 located on the same side are... A first collecting pipe 3 is fixedly connected to the bottom of several first collecting pipes 3, and a second guide pipe 9 is fixedly connected to the middle of the bottom of several second guide pipes 9. A second collecting pipe 10 is fixedly connected to the bottom of several second guide pipes 9. A third guide pipe 11 is fixedly connected to the middle of the bottom of the second collecting pipe 10. The third guide pipe 11 is connected to the rainwater storage tank 5.

One end of the water outlet pipe 6 extends to the bottom of the inner side of the rainwater storage tank 5. A pressure relief pipe 7 is fixedly connected to the bottom of one side of the rainwater storage tank 5. A solenoid valve 8 is fixedly installed at the connection between the pressure relief pipe 7 and the rainwater storage tank 5. A first filter screen 15, a second filter screen 16, and a third filter screen are set. 17. Multi-stage filtration of rainwater effectively removes impurities of different particle sizes and some harmful substances, improving the quality of collected rainwater and ensuring its subsequent utilization. Through the rational connection of the first guide pipe 2, the first collection pipe 3, the second guide pipe 9, the second collection pipe 10, and the third guide pipe 11, rainwater collected by each rainwater collection seat 1 is orderly gathered and guided into the rainwater storage tank 5, achieving efficient rainwater diversion and centralized storage. The design of the annular mounting seat 13 engaging with the fixing ring 14 and several connecting slots 18 engaging with several connecting blocks 19 makes the installation and disassembly of the filter assembly very convenient, facilitating regular cleaning of the filter screen. Alternatively, replacement can be used to reduce maintenance costs and work difficulty. Flow sensors 12 are installed in each of the first diversion pipes 2 to monitor the amount of rainwater collected per unit time in each rainwater collection seat 1 in real time. Data analysis is used to determine whether the rainwater collection seat 1 is blocked, and a signal is promptly sent to the client via the wireless signal transceiver module 22 to remind the management personnel to clean it, ensuring the collection efficiency of the device. The liquid level sensor 20 installed in the rainwater storage tank 5 can monitor the water level in real time to prevent rainwater overflow and ensure the safe operation of the device. The rainwater collection seat 1 adopts a funnel-shaped design, which increases the contact area with rainwater, enabling it to collect surface runoff rainwater more widely and quickly, thus improving rainwater collection efficiency.

[0022] In this embodiment, the rainwater storage tank 5 is the core storage component of the entire device. Its capacity is rationally planned according to actual needs to meet the rainwater storage requirements of areas of different sizes. A drain pipe 6 is fixedly connected to the top of one side of the rainwater storage tank 5, with one end extending to the bottom of the inner side of the rainwater storage tank 5. This design allows for maximum drainage of rainwater from the storage tank, minimizing residue. The drain pipe 6 can be used to guide the collected and stored rainwater to other areas requiring water, such as urban greening irrigation systems and landscape water replenishment, achieving secondary utilization of rainwater and improving the recycling rate of water resources. A pressure relief pipe 7 is fixedly connected to the bottom of one side of the water storage tank 5. A solenoid valve 8 is fixedly installed at the connection between the pressure relief pipe 7 and the rainwater storage tank 5. During urban rainfall, when the amount of rainwater collected is too large, causing the pressure inside the rainwater storage tank 5 to exceed the set safety value, the solenoid valve 8 will automatically open. At this time, the pressure relief pipe 7 can quickly discharge the excess rainwater in the rainwater storage tank 5, reduce the pressure inside the tank, prevent damage to the rainwater storage tank 5 due to excessive pressure, and ensure the safe and stable operation of the device. At the same time, the automatic control mode of the solenoid valve 8 can accurately adjust the drainage volume according to the actual pressure inside the rainwater storage tank 5, avoiding unnecessary waste of rainwater.

[0023] Example 3: Please see Figure 1-6This utility model provides a rainwater collection and diversion device for sponge cities, including several rainwater collection seats 1 and rainwater storage tanks 5. Each rainwater collection seat 1 has an annular mounting base 13 fixedly installed in the middle of its inner side. Each annular mounting base 13 has a fixing ring 14 engaged at its top. Each fixing ring 14 has a first filter screen 15 fixedly installed at its top inner side. Each fixing ring 14 has a second filter screen 16 fixedly installed in the middle of its inner side. Each fixing ring 14 has a third filter screen 17 fixedly installed at its bottom inner side. Each rainwater collection seat 1 has a first diversion pipe 2 fixedly connected to its bottom end. The bottom ends of the several first diversion pipes 2 located on the same side are connected to each other. Each rainwater collection base 1 is fixedly connected to a first collecting pipe 3. The middle of the bottom end of each of the first collecting pipes 3 is fixedly connected to a second guiding pipe 9. The bottom of each of the second guiding pipes 9 is fixedly connected to a second collecting pipe 10. The middle of the bottom end of each second collecting pipe 10 is fixedly connected to a third guiding pipe 11. The third guiding pipe 11 is connected to the rainwater storage tank 5. Each rainwater collection base 1 is funnel-shaped. All the rainwater collection bases 1, first guiding pipes 2, first collecting pipes 3, second guiding pipes 9, second collecting pipes 10, and third guiding pipes 11 are made of PVC material. A first filter screen 15, a second filter screen 16, and a third filter screen 17 are installed. Multi-stage filtration of rainwater effectively removes impurities of different particle sizes and some harmful substances, improving the quality of collected rainwater and ensuring its subsequent utilization. Through the rational connection of the first guide pipe 2, the first collection pipe 3, the second guide pipe 9, the second collection pipe 10, and the third guide pipe 11, rainwater collected by each rainwater collection station 1 is orderly gathered and guided into the rainwater storage tank 5, achieving efficient rainwater diversion and centralized storage. The design of the annular mounting base 13 engaging with the fixing ring 14 and several connecting slots 18 engaging with several connecting blocks 19 makes the installation and disassembly of the filter assembly very convenient, facilitating regular cleaning of the filter screen. Replacement reduces maintenance costs and workload. Flow sensors 12 are installed in each first guide pipe 2 to monitor the amount of rainwater collected per unit time in real time at each rainwater collection seat 1. Data analysis determines whether the rainwater collection seat 1 is blocked and promptly sends a signal to the client via the wireless signal transceiver module 22 to remind management personnel to clean it, ensuring the collection efficiency of the device.

[0024] In this embodiment, the rainwater collection seats 1 are configured in a funnel shape. This funnel design has significant advantages: its wider opening faces upwards, greatly increasing the contact area with rainwater, thus collecting surface runoff rainwater more widely and quickly during rainfall. Compared to traditionally shaped collection devices, the funnel-shaped rainwater collection seats 1 can collect more rainwater from different directions, effectively improving rainwater collection efficiency. Furthermore, its narrower opening faces downwards and connects to the subsequent diversion pipes, allowing the collected rainwater to flow more concentratedly and smoothly into the diversion system, reducing splashing and loss during the collection process. The rainwater collection seats 1, the first diversion pipes 2, the first collection pipes 3, the second diversion pipes 9, the second collection pipes 10, and the third diversion pipe 11 are all made of PVC. Made of PVC, this material boasts numerous excellent properties. First, it exhibits good corrosion resistance. In urban environments, rainwater may contain various acidic, alkaline substances and impurities, and PVC can resist the erosion of these substances, ensuring the long-term stable operation of the drainage device and preventing damage. Second, PVC is lightweight, making the entire drainage device easier and faster to install and transport, reducing construction difficulty and costs. Third, PVC has a relatively low cost, and its large-scale application in rainwater harvesting drainage devices can effectively control manufacturing costs, improving its economic viability and the possibility of widespread application. In addition, PVC also has a certain degree of flexibility, making it less prone to breakage under certain external forces, and adaptable to different terrains and installation environments.
