Description

Technical Field

[0001] This invention relates to the technical field of rainwater harvesting, and in particular to a rainwater harvesting system and rainwater recycling system for industrial parks. Background Technology

[0002] Industrial parks are specific areas that gather various production factors, provide production and services, and achieve industrial intensification and economic development. The completeness of infrastructure and the ability to prevent and control risks are crucial to the development of industrial parks. Rainwater harvesting system design is one of the important aspects of park infrastructure construction. In the overall planning of rainwater harvesting design, the entire industrial park's pipelines are often planned holistically to form a unified pipe network. Rainwater grates, inspection wells, and discharge outlets are then installed within this network, forming a traditional industrial park rainwater harvesting system.

[0003] Industrial parks typically include various production entities, such as chemical industrial parks and electroplating industrial parks. Because industrial parks usually cover a large area, they also have a large catchment area when it rains. In the event of heavy rain or sewage leakage accidents, industrial parks face significant challenges in rainwater collection and quality monitoring, making it difficult to respond quickly, accurately locate pollution sources, and effectively treat and dispose of polluted rainwater.

[0004] Risk monitoring is particularly important for chemical or electroplating industrial parks. These parks use large quantities of chemicals during production, which are highly volatile in the air. During rainfall, these volatile chemicals, along with oil and dust from the ground, can easily mix with rainwater, causing rainwater pollution. If this polluted rainwater is not effectively monitored, it will flow into the entire rainwater collection network, contaminating the entire network and potentially exceeding pollution standards. This significantly increases the difficulty and cost of subsequent treatment of the contaminated rainwater and its associated pipelines. This patent describes a rainwater collection device and rainwater recycling equipment for industrial parks. It aims to provide a novel rainwater collection system for industrial parks that can quickly and accurately locate and control rainwater sources, monitor rainwater collection and water quality, control rainwater pollution areas to a minimum, implement effective treatment and disposal, and prevent the pollution area from expanding. This system improves the risk response capabilities of industrial parks, reduces environmental pollution risks, and simultaneously achieves rainwater resource recycling. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an industrial park rainwater collection system and rainwater recycling system that can quickly and accurately locate and cut off the source of pollution, control the spread of polluted rainwater, and have good risk monitoring and emergency response effects.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An industrial park rainwater harvesting system includes:

[0008] A rainwater collection network, comprising a main pipeline and multiple unit area pipelines, each of which is provided with a unit area inlet.

[0009] The monitoring component includes an intelligent control system, multiple monitoring wells, multiple detection devices, multiple control valves, and multiple sensors. Each monitoring well is located at the corresponding inlet of the unit area and is connected to the main pipeline. Each monitoring well is equipped with a corresponding detection device, sensor, and control valve. Each detection device, sensor, and control valve is electrically connected to the intelligent control system. The detection device is used to detect the degree of rainwater exceeding the standard at the inlet of each unit area, and the sensor is used to control the opening and closing of the control valve.

[0010] A rainwater collection tank is provided, and the main pipeline is connected to the rainwater collection tank. The main pipeline is equipped with a valve, which is used to control the opening and closing of the rainwater collection tank.

[0011] In one embodiment, the monitoring well includes a monitoring well body, a well cover, a first inlet, a second inlet, and an outlet. A receiving cavity is formed within the monitoring well body. The first inlet, the second inlet, and the outlet are respectively connected to the receiving cavity. The receiving cavity is connected to the unit area pipeline via the first inlet and the second inlet, respectively. The receiving cavity is connected to the main pipeline via the outlet. The detection device is disposed on the outer wall of the monitoring well body. The control valve includes a first control valve and a second control valve. The first control valve is disposed within the first inlet, and the second control valve is disposed within the second inlet. The first and second control valves are electrically connected to the sensor. The well cover is used to cover the receiving cavity to form a closed cavity.

[0012] In one embodiment, the monitoring well further includes a first filter plate, which has a plurality of filter holes. The first filter plate is disposed in the receiving cavity, and each of the filter holes is connected to the receiving cavity.

[0013] In one embodiment, the first filter plate is engaged with the side wall of the receiving cavity.

[0014] In one embodiment, the unit area pipeline includes a first inflow transverse pipeline, an inflow longitudinal pipeline, and a second inflow transverse pipeline connected in sequence. The monitoring well is provided between the first inflow transverse pipeline and the inflow longitudinal pipeline, and the monitoring well is provided between the second inflow transverse pipeline and the inflow longitudinal pipeline. The first inflow transverse pipeline, the inflow longitudinal pipeline, the second inflow transverse pipeline, and each of the monitoring wells are connected to form a unidirectional flow pipe.

[0015] In one embodiment, the industrial park rainwater harvesting system further includes multiple flow wells, each of which is arranged side by side on the rainwater harvesting pipeline.

[0016] In one embodiment, a high-pressure pump is provided at the junction of the unit area.

[0017] In one embodiment, the main pipeline is a pre-embedded rigid waterproof sleeve; and / or,

[0018] The pipelines in the unit area are pre-embedded rigid waterproof sleeves.

[0019] A rainwater harvesting system includes the industrial park rainwater collection system described in any of the above embodiments.

[0020] In one embodiment, the rainwater harvesting system further includes a wastewater treatment pond.

[0021] Compared with the prior art, the present invention has at least the following advantages:

[0022] 1. The aforementioned industrial park rainwater harvesting system, due to the rainwater harvesting network comprising interconnected main pipelines and multiple unit area pipelines, divides the rainwater harvesting network within the industrial park into multiple different module unit area pipelines. This allows for the monitoring and management of independent unit area pipelines, reducing the difficulty of risk monitoring of the industrial park rainwater harvesting system. Furthermore, by setting up monitoring wells at the inflow point of each unit area, each monitoring well is equipped with corresponding detection devices, sensors, and control valves. This allows the detection devices, sensors, and control valves in each monitoring well to form multiple monitoring loops with the intelligent control system. When the rainwater in a monitoring well exceeds the standard, the detection device can quickly detect the degree of exceedance and feed the detection information back to the intelligent control system. The system can control the flow of rainwater exceeding the standard, and then the intelligent control system transmits this information to the sensors. The sensors then automatically activate the control valves, effectively preventing excessive rainwater from flowing into the unit area's inlet. This avoids cross-contamination of the entire pipe network by the excessive rainwater. This not only allows for the rapid and accurate identification and isolation of pollution sources, preventing rainwater from exceeding the standard unit area's pipes from entering the rainwater collection network and improving rainwater recycling rates, but also allows users to treat only the rainwater and pipes in the excessive unit area, reducing the difficulty of subsequent treatment of excessive rainwater and the cost of pipe cleaning. Furthermore, the clean rainwater treated in the wastewater treatment pond is recycled and reused, reducing water waste and improving the recycling rate of qualified rainwater.

[0023] 2. The aforementioned industrial park rainwater harvesting system, through the combined use of multiple monitoring wells, detection devices, control valves, and sensors, enables more precise and real-time monitoring of rainwater within different module unit areas. This helps control the spread of polluted rainwater, thereby improving the risk monitoring and emergency response capabilities for rainwater within the industrial park. It is particularly suitable for rainwater harvesting in chemical or electroplating industrial parks. Attached Figure Description

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] This application provides a rainwater harvesting system for industrial parks. The system includes a rainwater harvesting pipe network, a monitoring component, and a rainwater harvesting tank. The rainwater harvesting pipe network includes a main pipe and multiple unit area pipes, each unit area pipe having a unit area inlet. The monitoring component includes an intelligent control system, multiple monitoring wells, multiple detection devices, multiple control valves, and multiple sensors. Each monitoring well is located at a corresponding unit area inlet and is connected to the main pipe. Each monitoring well is equipped with a corresponding detection device, sensor, and control valve. Each detection device, sensor, and control valve is electrically connected to the intelligent control system. The detection device detects the excess rainwater level at each unit area inlet, and the sensor controls the opening and closing of the control valve. The main pipe is connected to the rainwater harvesting tank and is equipped with a valve. The valve controls the opening and closing of the rainwater harvesting tank.

[0039] The aforementioned industrial park rainwater harvesting system, due to its interconnected main pipeline and multiple unit area pipelines, divides the rainwater harvesting network within the industrial park into several different modular unit area pipelines. This allows for the monitoring and management of individual unit area pipelines, reducing the difficulty of risk monitoring for the industrial park's rainwater harvesting system. Furthermore, by installing monitoring wells at the inflow point of each unit area, each monitoring well is equipped with corresponding detection devices, sensors, and control valves. This allows the detection devices, sensors, and control valves in each monitoring well to form multiple monitoring loops with the intelligent control system. When the rainwater level in a monitoring well exceeds the standard, the detection device can quickly detect the degree of exceedance and feed the detection information back to the intelligent control system. The control system transmits this information to the sensors, which then automatically activate the control valves. This effectively prevents excessive rainwater from flowing into the unit area's inlet, thus avoiding cross-contamination of the entire pipe network. This not only allows for the rapid and accurate identification and isolation of pollution sources, preventing rainwater from exceeding standards from entering the rainwater collection network and improving rainwater recycling rates, but also allows users to treat only the rainwater and pipes in the excessively polluted unit area, reducing the difficulty of subsequent excessive rainwater treatment and pipe cleaning costs. The clean rainwater treated in the wastewater treatment pond is then recycled, reducing water waste and improving the recycling rate of qualified rainwater. Furthermore, the aforementioned industrial park rainwater collection system, by employing multiple monitoring wells, detection devices, control valves, and sensors, enables more precise and real-time monitoring of rainwater in different module unit areas, thereby improving the risk monitoring and emergency response capabilities for rainwater within the industrial park. It is especially suitable for rainwater collection in chemical industrial parks or electroplating industrial parks.

[0040] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0041] like Figures 1 to 3 As shown, an industrial park rainwater harvesting system 10 in one embodiment includes a rainwater harvesting pipe network 100, a monitoring component 200, and a rainwater harvesting tank 300. The rainwater harvesting pipe network 100 includes a main pipe 110 and multiple unit area pipes 120, which can be referred to in conjunction with the above. Figure 4 , Figure 5 and Figure 6Each unit area pipeline 120 is provided with a unit area inlet 130; the monitoring component 200 includes an intelligent control system (not shown), multiple monitoring wells 210, multiple detection devices 220, multiple control valves 230, and multiple sensors 240. Each monitoring well 210 is located at the corresponding unit area inlet 130, and each monitoring well 210 is connected to the main pipeline 110. Each monitoring well 210 is provided with a corresponding detection device 220, sensor 240, and control valve 240. The control valve 230, each of the aforementioned detection devices 220, each of the aforementioned sensors 240, and each of the aforementioned control valves 230 are electrically connected to the intelligent control system. The detection device 220 is used to detect the degree of rainwater exceeding the standard at the inflow point 130 of each of the aforementioned unit areas, and the sensor 240 is used to control the opening and closing of the control valve 230. The main pipeline 110 is connected to the rainwater collection tank 300, and the main pipeline 110 is equipped with a valve 310, which is used to control the opening and closing of the rainwater collection tank 300.

[0042] The aforementioned industrial park rainwater harvesting system 10, because the rainwater harvesting network 100 includes a main pipeline 110 and multiple unit area pipelines 120, divides the rainwater harvesting network 100 within the industrial park into multiple unit area pipelines 120 with different modules. This allows for the monitoring and management of individual unit area pipelines 120, reducing the difficulty of risk monitoring for the industrial park rainwater harvesting system 10. Furthermore, by setting up monitoring wells 210 at the confluence of each unit area, each monitoring well 210 is equipped with a corresponding detection device 220, sensor 240, and control valve 230. This allows the detection device 220, sensor 240, and control valve 230 within each monitoring well 210 to form multiple monitoring loops with the intelligent control system. When the rainwater level in a certain monitoring well 210 exceeds the standard, the detection device 220 can quickly detect the problem. The system logs the rainwater level in well 210 to detect any exceeding the standard and feeds the detection information back to the intelligent control system. The intelligent control system then transmits this information to sensor 240, which automatically activates control valve 230. This effectively prevents the excessive rainwater from flowing into the unit area's inlet, thus avoiding cross-contamination of the entire pipe network. This not only allows for the rapid and accurate identification and isolation of the pollution source to prevent excessive rainwater from entering the rainwater collection network 100, improving the rainwater recycling rate, but also allows users to treat only the rainwater and pipes in the unit area 120 that exceed the standard. This reduces the difficulty of subsequent treatment of excessive rainwater and the cost of pipe cleaning. Furthermore, the clean rainwater treated in the wastewater treatment pond is recycled and reused, reducing water waste and improving the recycling rate of qualified rainwater.

[0043] The aforementioned industrial park rainwater harvesting system 10, by employing the combined use of multiple monitoring wells 210, multiple detection devices 220, multiple control valves 230, and multiple sensors 240, can achieve more accurate and real-time monitoring of rainwater in different module unit areas, thereby improving the risk monitoring and emergency response capabilities for rainwater in industrial parks. It is particularly suitable for rainwater harvesting in chemical or electroplating industrial parks, enabling faster and more accurate source tracing and effective risk monitoring measures.

[0044] like Figure 6 and Figure 7 As shown, in one embodiment, the monitoring well 210 includes a monitoring well body 211, a well cover 212, a first inlet 213, a second inlet 214, and an outlet 215. A receiving cavity 2111 is formed within the monitoring well body 211. The first inlet 213, the second inlet 214, and the outlet 215 are respectively connected to the receiving cavity 2111. The receiving cavity 2111 is connected to the unit area pipeline 120 through the first inlet 213 and the second inlet 214, respectively. The receiving cavity 2111 is connected to the main pipeline 110 through the outlet 215. The detection device 220 is disposed within the monitoring well body. On the outer wall of body 211, the control valve 230 includes a first control valve 231 and a second control valve 232. The first control valve 231 is disposed in the first water inlet 213, and the second control valve 232 is disposed in the second water inlet 214. The first control valve 231 and the second control valve 232 are electrically connected to the sensor 240. The well cover 212 is used to cover the receiving cavity 2111 to form a closed cavity, so that the detection device 220 can effectively monitor the rainwater in the monitoring well 210. The first control valve 231 and the second control valve 232 can isolate and block the rainwater exceeding the standard to prevent the rainwater from flowing into the next stage. In addition, the receiving cavity 2111 can collect a certain amount of rainwater to provide backup water for fire.

[0045] Furthermore, since the first control valve 231 is located inside the first inlet 213 and the second control valve 232 is located inside the second inlet 214, the rainwater flowing into the receiving cavity 2111 through the first inlet 213 and the rainwater flowing into the receiving cavity 2111 through the second inlet 214 can be monitored. When the detection device 220, the first control valve 231, and the second control valve 232 can be electrically connected to an external controller, the first control valve 231 and the second control valve 232 can close the corresponding inlets. Alternatively, it can be opened. For example, when the monitoring data value shows that the rainwater in the first inlet 213 exceeds the standard, the first control valve 231 closes the first inlet 213. If the rainwater in the second inlet 214 exceeds the standard, the second control valve 232 closes the second inlet 214. This quickly and timely isolates the excessive rainwater from entering the receiving cavity 2111, preventing the excessive rainwater from causing cross-contamination of the entire pipe network. This achieves accurate and real-time monitoring of rainwater in different unit areas of the pipe 120.

[0046] Furthermore, in this embodiment, when a monitoring well 210 exceeds the standard, the monitoring well 210 adjacent to the one exceeding the standard can be closed at the same time. This allows the monitoring component 200 to more comprehensively block the excessive rainwater from entering the rainwater collection network 100, making the risk monitoring of rainwater by the industrial park rainwater collection system 10 more comprehensive and accurate.

[0047] like Figure 7 As shown, in one embodiment, the monitoring well 210 further includes a first filter plate 216. The first filter plate 216 has multiple filter holes and is disposed within the receiving cavity 2111. Each filter hole is connected to the receiving cavity 2111, enabling the first filter plate 216 to perform preliminary filtration of rainwater from the ground to obtain cleaner rainwater and improve the detection accuracy of the monitoring component 200. To facilitate user disassembly and assembly of the first filter plate 216, in one embodiment, the first filter plate 216 is engaged with the side wall of the receiving cavity 2111.

[0048] like Figure 1 As shown, to improve the collection of rainwater within the industrial park, in one embodiment, the unit area pipeline 120 includes a first horizontal inflow pipeline 121, a vertical inflow pipeline 122, and a second horizontal inflow pipeline 123 connected in sequence. A monitoring well 210 is disposed between the first horizontal inflow pipeline 121 and the vertical inflow pipeline 122, and between the second horizontal inflow pipeline 123 and the vertical inflow pipeline 122. The first horizontal inflow pipeline 121, the vertical inflow pipeline 122, the second horizontal inflow pipeline 123, and each monitoring well 210 are connected to form a unidirectional flow pipe. Please refer to [link / reference]. Figure 8 It is understandable that, since the industrial park includes multiple different factory buildings such as chemical industrial park and electroplating industrial park, the first horizontal inlet pipe 121, the vertical inlet pipe 122, and the second horizontal inlet pipe 123 are respectively arranged around the outer perimeter of a factory building and form a unidirectional flow pipe. On the one hand, this can increase the amount of rainwater collected around the factory building. On the other hand, the unidirectional flow pipe can effectively reduce the cross-contamination of rainwater in the unit area pipe 120, so as to improve the risk monitoring of the unit area pipe 120.

[0049] Furthermore, in one embodiment, the first transverse conduit 121 and the first end of the longitudinal conduit 122 form a first connection point, and the second transverse conduit 123 and the second end of the longitudinal conduit 122 form a second connection point, and the monitoring component 200 is provided at both the first connection point and the second connection point. It is understandable that, since monitoring components 200 are respectively installed at the first and second connection points, the monitoring components 200 can subdivide the unit area pipe 120 into multiple smaller monitoring modules, so that users can more quickly and accurately locate and cut off the source, effectively preventing excessive rainwater from entering the rainwater collection pipe network 100 and causing pollution to the entire rainwater collection pipe network 100 and the rainwater. This achieves better risk monitoring of rainwater in the unit area pipe 120, which not only improves the accuracy of rainwater collection pipe network 100, but also improves the recycling rate of other qualified rainwater in the unit area pipe 120, reduces the difficulty and cost of subsequent treatment of excessive rainwater, and reduces the cleaning length of the excessive unit area pipe 120 and the amount of water used during cleaning, thereby reducing the cleaning cost and water consumption of the excessive unit area pipe 120.

[0050] Please refer to Figure 8. In this embodiment, the industrial park rainwater harvesting system 10 further includes a risk monitoring component 21. The risk monitoring component 21 includes a risk monitoring pool 24, which is connected to the main pipeline 110. The risk monitoring pool 24 is equipped with a connected sewage outlet 22 and a wastewater discharge outlet 23. The sewage outlet 22 is used to connect to the municipal pipeline, and the wastewater discharge outlet 23 is used to connect to the rainwater harvesting pool 300. It can be understood that when a certain unit area pipeline 120 is polluted, the monitoring well 210 can quickly detect the corresponding unit area pipeline 120 and close the corresponding control valve, so that the excessive rainwater flows into the main pipeline 110 and into the risk monitoring pool 24, and then flows into the rainwater harvesting pool 300 through the wastewater discharge outlet 23. This achieves the recovery of the excessive rainwater. Furthermore, if the rainwater does not exceed the standard, the rainwater will flow to the sewage outlet 22 and finally flow into the municipal pipeline.

[0051] It should be noted that in practical applications, rainwater is discharged into the rainwater collection tank 300 15 minutes before collection. Since the rainwater collection pipe network 100, which has not been used for a long time, is prone to bacterial growth, which may lead to the rainwater failing to meet the standards, this application discharges rainwater into the rainwater collection tank 300 15 minutes before collection to prevent excessive rainwater from flowing into the municipal pipeline, thus ensuring that qualified rainwater enters the municipal pipeline and improving the accuracy of rainwater monitoring.

[0052] like Figure 1 As shown, in one embodiment, the unit area pipe 120 is configured as an open loop. It can be understood that the first horizontal inlet pipe 121, the vertical inlet pipe 122, and the second horizontal inlet pipe 123 are connected with a gap to prevent them from forming a closed loop. This ensures unidirectional flow in the unit area pipe 120, better preventing cross-contamination of rainwater between the first horizontal inlet pipe 121, the vertical inlet pipe 122, and the second horizontal inlet pipe 123.

[0053] In one embodiment, the first horizontal inflow pipe 121 and the second horizontal inflow pipe 123 are horizontally distributed in the industrial park, and the second vertical inflow pipe 122 is vertically distributed in the industrial park, so that the horizontal inflow pipes and the vertical inflow pipes 122 can be staggered in the industrial park. This improves the distribution area of ​​the unit area pipes 120 in the industrial park, thereby increasing the amount of rainwater collected in the industrial park and thus improving the rainwater recycling rate.

[0054] In one embodiment, the first transverse inlet pipe 121 is obliquely buried in the ground of the industrial park. It is understood that by obliquely burying the first transverse inlet pipe 121 in the ground, a certain height difference is created between the two ends of the first transverse inlet pipe 121, allowing rainwater from the industrial park to flow into the first transverse inlet pipe 121 more effectively and quickly, preventing excessive water accumulation on the industrial park's surface and thus improving the flood control effect. Similarly, in one embodiment, the second transverse inlet pipe 123 is obliquely buried in the ground of the industrial park to further improve the flow of rainwater from the industrial park's surface into the second transverse inlet pipe 123 more effectively and quickly, thereby further improving the horizontal flood control effect of the industrial park. Furthermore, in one embodiment, the longitudinal conduit 122 is obliquely buried in the ground of the industrial park to further improve the flow of rainwater from the industrial park into the longitudinal conduit 122 more effectively and quickly, thereby improving the vertical flood control effect of rainwater in the industrial park. This allows rainwater in the industrial park to flow into the unit area conduit 120 more comprehensively and quickly, which not only improves the recycling rate of rainwater in the industrial park, but also improves the flood control effect of rainwater in the industrial park.

[0055] In one embodiment, the first inlet transverse conduit 121 is inclined at an angle of 22° to 25° on the ground of the industrial park to achieve inclined burial of the first inlet transverse conduit 121.

[0056] In one embodiment, the inflow longitudinal pipe 122 is inclined at an angle of 12° to 20° on the ground of the industrial park to achieve inclined burial of the inflow longitudinal pipe 122.

[0057] In one embodiment, the second inlet transverse conduit 123 is inclined at an angle of 5° to 10° on the ground of the industrial park to achieve inclined installation of the second inlet transverse conduit 123.

[0058] In one embodiment, the first transverse inlet pipe 121 gradually slopes upward toward the ground from near the transverse inlet pipe 122 toward away from the transverse inlet pipe 122, the transverse inlet pipe 122 gradually slopes downward toward the ground from near the first transverse inlet pipe 121, and the second transverse inlet pipe 123 gradually slopes upward toward the ground from near the transverse inlet pipe 122. This arrangement results in the first transverse conduit 121 having an inclined first low-lying portion at the end near the longitudinal conduit 122, and an inclined first high-lying portion at the end away from the longitudinal conduit 122, thus achieving a high-low configuration for the first transverse conduit 121. Similarly, the longitudinal conduit 122 has an inclined second high-lying portion at the end near the first transverse conduit 121, and an inclined second low-lying portion at the end near the second transverse conduit 123, achieving a high-low configuration for the longitudinal conduit 122. Likewise, the second transverse conduit 123 has an inclined third low-lying portion at the end near the longitudinal conduit 122, and an inclined third high-lying portion at the end away from the longitudinal conduit 122. Furthermore, by adjusting the first transverse conduit... The inclination angle of the transverse pipe 121 is 22° to 25°, the inclination angle of the longitudinal pipe 122 is 12° to 20°, and the inclination angle of the second transverse pipe 123 is 5° to 10°. This allows the first transverse pipe 121, the second transverse pipe 123, and the longitudinal pipe to form a stepped slope, creating a stepped, unidirectional inclined flow unit area pipe 120. This not only enables the rapid collection of rainwater from the industrial park ground but also ensures a good flow velocity in the unit area pipe 120, allowing the rainwater in the unit area pipe 120 to flow more quickly into the rainwater collection tank 300. This achieves unidirectional rapid flow of rainwater in the unit area pipe 120, thus preventing large-scale water accumulation on the ground in the industrial park.

[0059] It should be noted that monitoring components 200 are installed at the first connection between the first horizontal inlet pipe 121 and the vertical inlet pipe 122, and at the second connection between the second horizontal inlet pipe 123 and the vertical inlet pipe 122. In order to avoid the rainwater flow velocity in the first horizontal inlet pipe 121 being too high and causing the detection results of the monitoring component 200 at the first connection to be inaccurate. Therefore, by setting the inclination angle of the first transverse conduit 121 to 22°–25°, the inclination angle of the longitudinal conduit 122 to 12°–20°, and the inclination angle of the second transverse conduit 123 to 5°–10°, the present invention achieves relatively gentle slopes in the inclination angles of the first transverse conduit 121, the longitudinal conduit 122, and the second transverse conduit 123. This avoids excessive fluctuations in the rainwater flow velocity within the unit area conduit 120, which could affect the accuracy of the monitoring component 200's detection. This enables more accurate detection of the unit area conduit 120, rapid detection and cut-off of excessive rainwater, and thus effective risk monitoring of rainwater in the industrial park.

[0060] In one embodiment, the first inflow transverse pipe 121 is further provided with a first intercepting plate, which is located on the side away from the ground. It can be understood that by adding a first intercepting plate inside the first inflow transverse pipe 121, the first intercepting plate can effectively slow down the flow velocity of rainwater entering the first inflow transverse pipe 121, thus preventing the rainwater flow velocity inside the first inflow transverse pipe 121 from being too high and affecting the accuracy of the detection by the monitoring component 200 at the first connection point. This ensures accurate real-time monitoring of rainwater in the unit area pipe 120, thereby improving the accuracy of rainwater monitoring in the industrial park. Similarly, in one embodiment, the second inflow transverse pipe 123 is further provided with a second intercepting plate, which is located on the side away from the ground, to effectively slow down the flow velocity of rainwater entering the second inflow transverse pipe 123, thus preventing the rainwater flow velocity inside the second inflow transverse pipe 123 from being too high and affecting the accuracy of the detection by the monitoring component 200 at the second connection point. In addition, the first and second intercepting plates can effectively block the silt in the rainwater in the unit area, thereby preventing a large amount of silt from entering the monitoring component 200 and affecting the accuracy of the monitoring component 200's detection.

[0061] In one embodiment, both the first and second intercepting plates are hourglass-shaped. Understandably, the hourglass-shaped first intercepting plate disperses rainwater in the first inflow transverse pipe 121 into multiple streams, effectively reducing the impact of the incoming rainwater on the first inflow transverse pipe 121, thus providing better protection for it. It also effectively slows down the flow rate of the rainwater in the first inflow transverse pipe 121, ensuring the accuracy of detection by the monitoring component 200 at the first connection. Similarly, the hourglass-shaped second intercepting plate disperses rainwater in the second inflow transverse pipe 123 into multiple streams, effectively reducing the impact of the incoming rainwater on the second inflow transverse pipe 123, thus providing better protection for it. It also effectively slows down the flow rate of the rainwater in the second inflow transverse pipe 123, ensuring the accuracy of detection by the monitoring component 200 at the second connection.

[0062] Furthermore, since the hourglass-shaped first and second intercepting plates gradually increase in size from the middle to both ends, a symmetrical flow avoidance section is formed in the middle, so that the incoming rainwater can be better dispersed through the symmetrical flow avoidance section in the middle. This effectively avoids the deformation of the first and second intercepting plates due to the impact of rainwater, ensuring that the first and second intercepting plates are not easily deformed under long-term use, thereby extending the service life of the first and second intercepting plates and ensuring that the rainwater in the first and second inlet transverse pipes 121 and 123 has a better interception and dispersion effect.

[0063] To increase the amount of rainwater collected within the industrial park, in one embodiment, the industrial park rainwater collection system 10 further includes multiple flow wells 400. Each flow well 400 is arranged side-by-side on the rainwater collection pipe network 100, and the flow wells 400 are spaced apart along the length of the rainwater collection pipe network 100. It can be understood that by adding multiple flow wells 400 to the rainwater collection pipe network 100, the distribution of the rainwater collection pipe network 100 within the industrial park can be improved, thereby achieving better collection of surface rainwater from the industrial park and increasing the recycling rate of surface rainwater in the industrial park.

[0064] like Figure 1As shown, in one embodiment, first collecting pipes 1211 are respectively arranged on both sides away from the first transverse inlet pipe 121, thereby improving the distribution of the first transverse inlet pipe 121 in the industrial park and improving the collection of rainwater from the industrial park's surface. Similarly, second collecting pipes 1221 are respectively arranged on both sides away from the longitudinal inlet pipe 122, thereby improving the distribution of the longitudinal inlet pipe 122 in the industrial park and improving the collection of rainwater from the industrial park's surface. Similarly, third collecting pipes 1231 are respectively arranged on both sides away from the second transverse inlet pipe 123, thereby improving the distribution of the longitudinal inlet pipe 122 in the industrial park and improving the collection of rainwater from the industrial park's surface.

[0065] In one embodiment, a Y-shaped first gathering portion is formed at one end of the first inflow transverse pipe 121 away from the inflow longitudinal pipe 122, which can further increase the amount of rainwater collected by the first inflow transverse pipe 121.

[0066] In one embodiment, a Y-shaped second collecting section is formed at one end of the second inflow transverse pipe 123 away from the inflow longitudinal pipe 122. The second collecting section can further increase the amount of rainwater collected by the second inflow transverse pipe 123, thereby improving the rainwater recycling rate.

[0067] In one embodiment, each of the flow wells 400 is equipped with a second filter plate. It is understood that by adding a second filter plate to each flow well 400, the filter plate can perform preliminary filtration of rainwater from the industrial park ground to obtain cleaner rainwater. This effectively prevents blockage of the unit area pipes 120, ensuring that rainwater from the industrial park ground can enter the rainwater collection tank 300 more quickly. Furthermore, it also ensures the detection accuracy of the monitoring component 200, preventing fallen leaves or garbage from flowing in and obstructing the detection sensitivity of the monitoring component 200's detection device 220 and sensor 240. Further, each of the second filter plates is detachably connected to the transition well. Since the second filter plates are prone to blockage or damage under long-term use, the detachable connection between the second filter plate and the transition well allows users to quickly replace blocked or damaged second filter plates.

[0068] In this embodiment, the main pipeline 110 includes a main pipeline body 111 and a plurality of connecting pipes 112. Each connecting pipe 112 is connected to the second inlet 214 of the corresponding monitoring well 210. The first inlet 213 is connected to one end of the main pipeline 110, and the outlet 215 is connected to the other end of the main pipeline 110, so that the connecting pipe 112 and the main pipeline 110 form a junction 130, thereby realizing the connection between the main pipeline 110, the monitoring well 210 and the unit area pipeline 120.

[0069] In one embodiment, the main pipe body 111 is arranged around the outer perimeter of the entire industrial park, so that the main pipe body 111 can surround the outer perimeter of the entire industrial park, realizing a more comprehensive coverage of the entire industrial park by the rainwater collection network 100, and forming a more comprehensive coverage with multiple unit area pipes 120, so as to better improve the rainwater recycling rate of the industrial park.

[0070] In one embodiment, the industrial park rainwater harvesting system 10 further includes multiple alarms, each alarm being installed on a corresponding monitoring well 210. The alarm is used to monitor and alert the monitoring well 210. When the rainwater in a monitoring well 210 exceeds the standard, the alarm can issue an alarm message so that the user can accurately and quickly find the specific rainwater exceeding the standard based on the alarm and take timely prevention and control measures for the rainwater exceeding the standard, thereby achieving better risk monitoring of rainwater in the industrial park.

[0071] In one embodiment, the industrial park rainwater harvesting system 10 also includes a vehicle-mounted pump for quickly extracting rainwater exceeding the standard. It is understood that when excessive rainwater is detected in a monitoring well 210, the first control valve 231 or the second control valve 232 is intelligently closed to block the excessive rainwater. Simultaneously, an alarm is triggered, allowing the user to quickly locate the excessive rainwater based on the alarm information, open the monitoring well 210, and then use the vehicle-mounted pump to quickly remove the excessive rainwater, thereby preventing the excessive rainwater from flowing into the rainwater collection network 100 and causing cross-contamination of the pipes 120 in different unit areas.

[0072] For example Figure 1 and Figure 5As shown, in one embodiment, the industrial park rainwater harvesting system 10 further includes multiple temporary storage tanks 600, each of which is located next to a monitoring well 210. The temporary storage tank 600 is used to collect excess rainwater. It is understood that because the inlet of the unit area pipe 120 where the excess rainwater is located is closed, water accumulation is likely to occur at that location, especially during heavy rainstorms when the truck-mounted pump has not yet arrived on site, leading to widespread water accumulation on the industrial park ground. Therefore, this invention adds temporary storage tanks 600 next to the monitoring well 210, allowing the temporary storage tanks 600 to be connected to the unit area pipe 120. This enables the temporary storage tanks 600 to effectively collect excess rainwater, preventing water accumulation on the industrial park ground.

[0073] In one embodiment, each of the first inflow transverse pipes 121 is provided with a temporary storage tank 600, each of the inflow longitudinal pipes 122 is provided with a temporary storage tank 600, and each of the second inflow transverse pipes 123 is provided with a temporary storage tank 600. This avoids the phenomenon of water accumulation on the ground of the industrial park.

[0074] In one embodiment, each of the temporary storage tanks 600 is equipped with a third control valve, and the third control valve is electrically connected to the corresponding intelligent control system. Thus, when the detection device 220 detects that the rainwater in a certain monitoring well 210 exceeds the standard, it can quickly feed the information back to the intelligent control system, and the intelligent control system will close the corresponding first control valve 231 or second control valve 232, and at the same time open the corresponding third control valve in the temporary storage tank 600, so that the excessive rainwater can flow into the temporary storage tank 600, avoiding the phenomenon of water accumulation on the ground of the industrial park.

[0075] like Figure 5 As shown, in one embodiment, the temporary storage tank 600 is equipped with a connecting pump 610 to facilitate quick connection between the connecting pump 610 and the vehicle-mounted pump. Furthermore, the connecting pump 610 protrudes within the temporary storage tank 600 and is flush with the industrial area ground. This avoids the connecting pump 610 being exposed on the ground, allowing users to quickly activate and connect the connecting pump 610, enabling the vehicle-mounted pump to rapidly pump away excess rainwater and prevent water accumulation in the industrial park. Furthermore, because the connecting pump 610 is flush with the industrial area ground, it prevents pedestrians from tripping over it, thus improving the safety of the industrial park rainwater harvesting system 10.

[0076] To enable rainwater collected in the unit area to flow more quickly into the next stage, in one embodiment, a high-pressure pump 500 is installed at the unit area inlet 130 to increase the flow rate of the rainwater, thereby allowing the rainwater to flow into the rainwater collection tank 300 more quickly. In this embodiment, the high-pressure pump 500 is a high-pressure submersible pump.

[0077] To facilitate the pre-installation of the rainwater harvesting network 100, in one embodiment, the main pipe 110 is a pre-embedded rigid waterproof sleeve. Compared to traditional cement pipes, the pre-embedded rigid waterproof sleeve has a smaller diameter, making it easier for users to pre-install, i.e., a shallower pre-installation depth. Furthermore, the interconnectivity of each pre-embedded rigid waterproof sleeve is better, thereby effectively preventing leakage in the main pipe 110. Similarly, in other embodiments, the unit area pipe 120 is a pre-embedded rigid waterproof sleeve, effectively preventing leakage in the unit area pipe 120, thus improving the sealing performance of the rainwater harvesting network 100 and allowing more rainwater to flow into the rainwater collection tank 300.

[0078] In this embodiment, the pre-embedded rigid waterproof sleeve is an HDPE (High Density Polyethylene) double-wall corrugated pipe. It can be understood that because the double-wall corrugated pipe can further increase the total flow rate of the unit area pipe 120, rainwater from the industrial park ground can quickly flow into the unit area pipe 120, effectively preventing water accumulation on the industrial park ground. Furthermore, the double-wall corrugated pipe has good anti-leakage performance, effectively preventing rainwater leakage from the rainwater collection network 100, thereby improving the rainwater recycling rate.

[0079] like Figure 8 As shown, this application also provides a rainwater harvesting system, including the industrial park rainwater collection system 10 described in any of the above embodiments. It is understood that the above-described rainwater harvesting system not only increases the amount of rainwater collected but also prevents leakage in the rainwater collection network 100. Furthermore, it enables individual real-time monitoring of the pipes 120 in each unit area to quickly and accurately locate excessive rainwater, allowing users to take timely preventative measures. This effectively prevents excessive rainwater from flowing into the rainwater collection network 100 and causing cross-contamination, thereby improving the risk monitoring index of rainwater within the industrial park, enabling rapid source identification and control, and reducing the difficulty and cost of subsequent rainwater treatment.

[0080] In one embodiment, the rainwater harvesting system further includes a wastewater treatment pond. It is understood that by discharging rainwater from the rainwater collection pond 300 to the wastewater treatment pond for chemical treatment, the various indicators of the rainwater meet the standards for use. Finally, the rainwater treated in the wastewater treatment pond is recycled to a wastewater treatment chemical dosing tank or a greywater reuse system for further recycling, thereby improving the rainwater recovery rate.

[0081] Compared with the prior art, the present invention has at least the following advantages:

[0082] 1. The aforementioned industrial park rainwater harvesting system 10, because the rainwater harvesting network 100 includes a main pipeline 110 and multiple unit area pipelines 120, divides the rainwater harvesting network 100 in the industrial park into multiple unit area pipelines 120 with different modules, so that the independent unit area pipelines 120 can be monitored and managed, reducing the difficulty of risk monitoring of the industrial park rainwater harvesting system 10; and by setting a monitoring well 210 at the inlet of each unit area, each monitoring well 210 is equipped with a corresponding detection device 220, sensor 240 and control valve 230, so that the detection device 220, sensor 240 and control valve 230 in each monitoring well 210 can form multiple monitoring loops with the intelligent control system. When the rainwater in a certain monitoring well 210 exceeds the standard, the detection device 220 can quickly detect it. The system monitors the level of rainwater exceeding the standard in well 210 and feeds the detection information back to the intelligent control system. The intelligent control system then transmits this information to sensor 240, which automatically activates control valve 230. This effectively prevents excessive rainwater from flowing into the unit area's inlet, thus avoiding cross-contamination of the entire pipe network. In this way, the pollution source can be quickly and accurately located and isolated to prevent excessive rainwater from entering the rainwater collection pipe network 100, improving the rainwater recycling rate. Furthermore, users only need to treat the rainwater and pipes in the unit area 120 that exceed the standard, reducing the difficulty of subsequent treatment of excessive rainwater and the cost of pipe cleaning. The clean rainwater treated in the wastewater treatment pond is then recycled and reused, which not only reduces water waste but also improves the recycling rate of qualified rainwater.

[0083] 2. The aforementioned industrial park rainwater harvesting system 10, by employing the combined use of multiple monitoring wells 210, multiple detection devices 220, multiple control valves 230, and multiple sensors 240, can achieve more accurate and real-time monitoring of rainwater in different module unit areas, thereby controlling the spread of polluted rainwater and improving the risk monitoring and emergency response capabilities for rainwater in industrial parks. It is particularly suitable for rainwater harvesting in chemical industrial parks or electroplating industrial parks.

[0084] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
