AI Technical Summary
Traditional rainwater and sewage separation devices lack intelligent adjustment mechanisms, making it difficult to dynamically adjust the separation strategy based on real-time rainfall and water quality. This leads to sewage easily clogging the filter screen and accumulating upstream, making it impossible to effectively separate rainwater and sewage. Furthermore, high-concentration pollutants can easily be directly discharged into rivers, resulting in high equipment maintenance costs and poor adaptability.
A diversion valve equipped with a water quality testing probe and a rainfall monitor is used. The controller monitors water quality and rainfall in real time and automatically adjusts the valve plate position to achieve flexible diversion of rainwater and sewage. When the water quality is qualified, it is discharged into the river; otherwise, it is discharged into the sewage pipeline.
It enables flexible diversion based on real-time water quality and rainfall, avoiding river pollution, reducing equipment maintenance costs, and improving the adaptability and processing capacity of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of rainwater and sewage diversion technology, specifically to a rainwater and sewage diversion device. Background Technology
[0002] Rainwater and sewage separation refers to a sewage discharge method in which rainwater and sewage are transported and discharged or subsequently treated through separate pipelines. Rainwater is discharged directly into rivers through a rainwater pipe network, while sewage is collected through a sewage pipe network and sent to a sewage treatment plant for treatment, thus preventing sewage from directly entering rivers and causing pollution. Furthermore, the collection, utilization, and centralized management of rainwater discharge can reduce the impact of water volume on sewage treatment plants and ensure their treatment efficiency.
[0003] Traditional rainwater and sewage separation devices mostly rely on fixed-structure filter screens for physical separation, lacking intelligent adjustment mechanisms. They are difficult to dynamically adjust the separation strategy according to real-time rainfall and water quality. When rainfall is too heavy, dirt easily clogs the filter screen and is difficult to clean in time, leading to the accumulation of rainwater and sewage upstream. This makes it impossible to effectively achieve the function of rainwater and sewage separation, and it is easy to cause sewage overflow or rainwater pipe network pollution. In heavy rain or rainstorm weather, they often face the problem of insufficient treatment capacity.
[0004] In addition, traditional devices are not good at treating initial rainwater, and there is a high risk of high-concentration pollutants being directly discharged into rivers. Furthermore, the equipment has high maintenance costs and poor adaptability, making it difficult to meet the needs of complex urban drainage environments. Utility Model Content
[0005] The purpose of this invention is to provide a rainwater and sewage separation device to address the shortcomings of existing technologies and solve the problems mentioned in the background art.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A rainwater and sewage separation device includes a rainwater receiving pipe buried in the soil, a diversion valve connected to the outlet end of the rainwater receiving pipe, a rainwater discharge pipe and a diversion pipe respectively connected to the two ends of the diversion valve away from the rainwater receiving pipe, and a sewage discharge pipe connected to the end of the diversion pipe.
[0008] A water quality detection probe is embedded and fixedly connected to the side wall of the rainwater receiving pipe, and the control end of the diversion valve is connected to a rain gauge located on the ground.
[0009] The diversion valve includes a valve body, an end cap fixed to the upper port of the valve body, and a valve stem controller fixed to the top surface of the end cap. The outer surface of the valve body is fixedly connected in a ring array with an inlet port, a second outlet port, and a first outlet port. A valve stem is rotatably arranged inside the valve body, and a valve plate is fixedly connected to the outer ring of the valve stem.
[0010] As a preferred embodiment of the rainwater and sewage separation device, the inlet port, the first drain port and the second drain port are all at an angle of 120° to each other.
[0011] As a preferred embodiment of the rainwater and sewage separation device, the valve stem controller has a drive motor inside, and the output shaft of the drive motor passes through the end cover and is fixedly connected to the top of the valve stem.
[0012] As a preferred embodiment of the rainwater and sewage separation device, the inlet port, the port furthest from the valve body, is connected to the outlet end of the rainwater receiving pipe; the second drain port, the port furthest from the valve body, is connected to the inlet of the rainwater discharge pipe; and the first drain port, the port furthest from the valve body, is connected to the port of the separation pipe furthest from the sewage discharge pipe.
[0013] As a preferred embodiment of the rainwater and sewage separation device, the end of the rainwater discharge pipe is connected to the river outlet, and the end of the sewage discharge pipe is connected to the municipal sewage pipeline.
[0014] As a preferred embodiment of the rainwater and sewage separation device, the bottom end of the valve stem is rotatably connected to the bottom side wall of the inner cavity of the valve body, and a sealing ring is provided on the outer surface of the valve plate.
[0015] As a preferred embodiment of the rainwater and sewage separation device, the water quality data from the water quality detection probe and the rainfall data from the rainfall monitor are both connected to the receiver inside the valve stem controller via a control cable. This is used to rotate the valve plate when the water quality data is qualified and there is rainwater, thereby allowing the rainwater inside the rainwater receiving pipe to be discharged into the second drainage port, and vice versa.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The rainwater and sewage separation device of this utility model monitors rainwater quality in real time through a water quality detection probe and rainfall in real time through a rainfall monitoring instrument, and transmits the data to the valve stem controller, thereby achieving flexible separation based on water quality and rainfall.
[0018] When the water quality is up to standard and it rains, the valve stem controller controls the valve stem to drive the valve plate to open the second drainage port, and the rainwater is discharged into the river through the rainwater discharge pipe to avoid polluting the river and to replenish the water source.
[0019] When the water quality is substandard or there is no rain, open the first drainage port and the liquid will be discharged into the municipal sewage pipeline through the diversion pipe and sewage discharge pipe to prevent sewage from entering the river. Attached Figure Description

[0030] Example 1:
[0031] like Figures 1 to 3 As shown, this embodiment provides a rainwater and sewage diversion device, including a rainwater receiving pipe 1, a diversion valve 2 connected to the outlet end of the rainwater receiving pipe 1, a rainwater discharge pipe 5 and a diversion pipe 8 respectively connected to the two ends of the diversion valve 2 away from the rainwater receiving pipe 1, and a sewage discharge pipe 6 connected to the end of the diversion pipe 8.
[0032] The diverter valve 2 includes a valve body 201, an end cap 202 fixed to the upper port of the valve body 201, and a valve stem controller 203 fixed to the top surface of the end cap 202. The outer surface of the valve body 201 is fixedly connected in a ring array with an inlet port 204, a second drain port 208 and a first drain port 206. A valve stem 207 is rotatably disposed inside the valve body 201, and a valve plate 205 is fixedly connected to the outer ring of the valve stem 207.
[0033] During installation, the rainwater receiving pipe 1 is buried in the soil, and its outlet end is connected to the inlet port 204 of the diversion valve 2. On the valve body 201 of the diversion valve 2, the inlet port 204, the first drain port 206, and the second drain port 208 are distributed at a 120° angle to each other. The port of the second drain port 208 furthest from the valve body 201 is connected to the inlet of the rainwater discharge pipe 5, and the end of the rainwater discharge pipe 5 is connected to the river outlet; the port of the first drain port 206 furthest from the valve body 201 is connected to the port of the diversion pipe 8 furthest from the sewage discharge pipe 6, and the end of the sewage discharge pipe 6 is connected to the municipal sewage pipeline.
[0034] A water quality detection probe 7 is embedded and fixedly connected to the side wall of the rainwater receiving pipe 1. A rainfall monitor 4 is connected to the control end of the diversion valve 2. During installation, the rainfall monitor 4 is placed in a suitable position on the ground. The water quality data of the water quality detection probe 7 and the rainfall data of the rainfall monitor 4 are both connected to the receiver inside the valve stem controller 203 through the control cable 3.
[0035] The bottom end of the valve stem 207 of the diverter valve 2 is rotatably connected to the bottom side wall of the inner cavity of the valve body 201. A sealing ring is provided on the outer surface of the valve plate 205 fixedly connected to the outer ring of the valve stem 207. The output shaft of the drive motor inside the valve stem controller 203 passes through the end cover 202 and is fixedly connected to the top end of the valve stem 207.
[0036] When the water quality detection probe 7 detects that the water quality data is qualified and the rainfall monitoring instrument 4 detects rainwater, the valve stem controller 203 receives the signal and controls the drive motor to rotate the valve stem 207. The valve stem 207 drives the valve plate 205 to rotate, so that the rainwater inside the rainwater receiving pipe 1 is discharged into the second drainage port 208, and then discharged into the river outlet through the rainwater discharge pipe 5. When the water quality data is unqualified or there is no rainwater, the valve stem controller 203 controls the valve plate 205 to rotate, so that the liquid inside the rainwater receiving pipe 1 is discharged into the first drainage port 206, and then discharged into the municipal sewage pipeline through the diversion pipe 8 and the sewage discharge pipe 6.
[0037] When installing the rainwater and sewage separation device, the burial depth of the rainwater receiving pipe 1 can be adjusted appropriately according to the actual soil conditions and the surrounding environment, as long as its outlet end can be smoothly and tightly connected to the inlet port 204 of the diversion valve 2.
[0038] The angle of each port on the valve body 201 of the diversion valve 2 remains unchanged at 120°. When connecting the rainwater discharge pipe 5 and the sewage discharge pipe 6, the degree of curvature and length of the pipe can be adjusted appropriately according to the site terrain and pipe route, but it is necessary to ensure that the connection is firm and there is no risk of leakage.
[0039] The water quality testing probe 7 should be embedded in the side wall of the rainwater receiving pipe 1 in a location that best represents the rainwater quality. The rainfall monitoring instrument 4 should be placed in an open, unobstructed location to ensure accurate rainfall monitoring. After the valve stem controller 203 is connected to the water quality testing probe 7 and the rainfall monitoring instrument 4 via the control cable 3, preliminary debugging should be performed to check whether the signal transmission is normal.
[0040] In actual use, when encountering light rain and good water quality, the rain monitor 4 detects a small amount of rain, the water quality detection probe 7 detects a qualified water quality signal, and the valve stem controller 203 controls the valve stem 207 to rotate a certain angle according to the received signal, so that the valve plate 205 is in a suitable position, allowing rainwater to be discharged into the river outlet through the second drain port 208 and the rainwater discharge pipe 5.
[0041] When encountering heavy rain and the rainwater contains a lot of impurities, resulting in substandard water quality, the valve stem controller 203 receives the corresponding signal and controls the valve stem 207 to rotate in the opposite direction, causing the valve plate 205 to change position, so that the rainwater is discharged into the municipal sewage pipeline through the first drain port 206, the diversion pipe 8 and the sewage discharge pipe 6.
[0042] Example 2:
[0043] This rainwater and sewage separation device is used in urban old residential area renovation projects. During installation, due to the complexity of underground pipelines in old residential areas, the laying of rainwater receiving pipe 1 needs to avoid the original underground pipelines, and a segmented excavation and laying method can be adopted.
[0044] Diversion valve 2 is installed in a relatively open and easily accessible location within the community. The ports on its valve body 201 are set at a 120° angle and are respectively connected to rainwater receiving pipe 1, rainwater discharge pipe 5, and diversion pipe 8. Rainwater discharge pipe 5 is laid along the edge of the community to the nearby river outlet, and sewage discharge pipe 6 is connected to the community's existing municipal sewage pipeline.
[0045] The water quality detection probe 7 is installed on the rainwater receiving pipe 1 near the diversion valve 2 so as to detect the quality of the rainwater that is about to enter the diversion valve 2 more timely and accurately.
[0046] The rainfall monitoring instrument 4 is installed on the roof of a high building in the community to ensure comprehensive monitoring of rainfall within the community.
[0047] The valve stem controller 203 is installed above the diversion valve 2 in a convenient position for operation and observation. After being connected to the water quality detection probe 7 and the rainfall monitor 4 via the control cable 3, the system is debugged. During the debugging process, different water quality and rainfall conditions are simulated to check whether the valve stem controller 203 can accurately control the movement of the valve stem 207 and the valve plate 205.
[0048] In actual operation, when there is short-term heavy rainfall in the afternoon in summer and the water quality is good, the rain monitor 4 quickly detects a large amount of rainwater signal, the water quality detection probe 7 detects qualified water quality signal, and the valve stem controller 203 immediately controls the valve stem 207 to rotate quickly, so that the valve plate 205 opens the second drainage port 208, allowing rainwater to be discharged into the river outlet through the rainwater discharge pipe 5, reducing the drainage pressure of the community.
[0049] When a lot of leaves fall in autumn and rainwater is mixed with leaves and other impurities, causing the water quality to be substandard, even if there is rainwater, the valve stem controller 203 will control the valve plate 205 to open the first drain port 206 according to the signal of the water quality detection probe 7, so as to discharge the rainwater into the municipal sewage pipeline and avoid pollution of the river.
[0050] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:
[0051] Rainwater receiving pipe 1 is buried in the soil to collect rainwater. During the flow of rainwater, water quality detection probe 7, which is embedded and fixed on the side wall of rainwater receiving pipe 1, detects the rainwater quality in real time and transmits the water quality data to the receiver inside valve stem controller 203 on the top surface of valve body 201 of diversion valve 2 via control cable 3.
[0052] Meanwhile, the rainfall monitoring instrument 4 located on the ground monitors the rainfall, and the monitored rainfall data is also transmitted to the receiver inside the valve stem controller 203 via the control cable 3.
[0053] When the valve stem controller 203 receives qualified water quality data transmitted by the water quality detection probe 7 and the rainfall monitoring instrument 4 transmits a rainwater signal, the valve stem controller 203 controls the internal drive motor to work. The output shaft of the drive motor drives the valve stem 207 to rotate, and the valve stem 207 drives the valve plate 205 to rotate, so that the valve plate 205 is in a suitable position and the second drain port 208 is opened. At this time, the rainwater inside the rainwater receiving pipe 1 enters the rainwater discharge pipe 5 through the inlet port 204, the inner cavity of the valve body 201, and the second drain port 208 in sequence, and finally discharges into the river outlet through the rainwater discharge pipe 5.
[0054] When the valve stem controller 203 receives water quality data from the water quality detection probe 7 that is unqualified or a no-rain signal from the rainfall monitor 4, the valve stem controller 203 controls the drive motor to rotate the valve stem 207 in the opposite direction. The valve stem 207 drives the valve plate 205 to rotate, so that the valve plate 205 is in another suitable position, opening the first drain port 206. At this time, the liquid inside the rainwater receiving pipe 1 enters the diversion pipe 8 through the inlet port 204, the inner cavity of the valve body 201, and the first drain port 206 in sequence, and then enters the sewage discharge pipe 6 through the diversion pipe 8, and finally is discharged into the municipal sewage pipeline.
[0055] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
