[0046] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0048] In urban planning and environmental protection, the discharge and treatment of rainwater and sewage is a crucial issue. Traditional rainwater drainage systems typically include rainwater pipes and wells, but these facilities are often ineffective in intercepting and discharging rainwater, especially during heavy rain or storms. Therefore, to solve the problem of rainwater interception and discharge, interception wells are mainly used for rainwater interception and discharge treatment.

[0049] An intercepting well is a water treatment facility that centrally treats combined rainwater and sewage. Traditional intercepting wells are made of reinforced concrete and have an overflow weir inside. One side of the weir is connected to a combined pipe to receive incoming water and a sewage pipe at the same time; the other side of the weir is connected to an overflow pipe, which is connected to a rainwater pipe to send the overflowing water into the river.

[0050] However, traditional interception wells cannot prevent sewage from mixing with rainwater.

[0051] This application provides a solution in which a target liquid level sensor monitors the target water level information in the well body, and a first flow sensor monitors the first flow rate in the sewage pipe. This can detect changes in rainwater in the well body and sewage in the sewage pipe in a timely manner. When the first flow rate is greater than the preset flow rate or the target water level information is greater than the preset water level, the interception device is controlled to close the second inlet, which can prevent sewage from mixing with rainwater, thereby effectively controlling the discharge of rainwater and sewage.

[0052] The following embodiments of this application will describe the intercepting well used in the technical implementation of this application:

[0053] This application provides a first embodiment of a diversion well, with reference to... Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the intercepting well of this application. The intercepting well includes:

[0054] Well body 10, the well body includes a water outlet 103, a first water inlet 101 connected to a sewage pipe 11, and a second water inlet 102 connected to a rainwater pipe 12;

[0055] A flow interceptor 13 is provided at the second water inlet 102;

[0056] A first flow sensor 14 is disposed inside the sewage pipe 11 and is used to collect the first flow rate of the sewage pipe 11.

[0057] The target liquid level sensor 15 is installed inside the well body 10 and is used to detect the target water level information of the well body 10;

[0058] An automatic control device 16 is connected to both the target liquid level sensor 15 and the first flow sensor 14. It is used to control the interception device 13 to close the second water inlet 102 if the first flow rate is greater than the preset flow rate or the target water level information is greater than the preset water level.

[0059] In this embodiment, the intercepting well is a commonly used interception facility in urban drainage systems, used to collect and intercept rainwater and sewage to reduce the pressure on the drainage system.

[0060] The intercepting well 10 is equipped with a first inlet 101 and a second inlet 102. The first inlet 101 is connected to the sewage pipe 11, and the second inlet 102 is connected to the rainwater pipe 12. During rainfall, rainwater and sewage can enter the well 10 through the rainwater pipe 102 and the sewage pipe 11, respectively. The well 10 has a certain volume, which can intercept a portion of the rainwater and sewage. When needed, the mixture of sewage and rainwater is gradually discharged into the drainage system through the outlet 103, thereby smoothing the load on the drainage system and reducing the impact of rainwater on the drainage system. The automatic control device 16 can be a processor with data acquisition, analysis, and processing functions.

[0061] Specifically, refer to Figure 2 As shown, the automatic control device 16 can be wirelessly connected to the first flow sensor 14, the target liquid level sensor 15, and the flow control device 13. After the automatic control device 16 is connected to the first flow sensor 14 and the target liquid level sensor respectively, the automatic control device 16 can periodically collect the first flow rate collected by the first flow sensor 14 and the target water level information of the well body collected by the target liquid level sensor 15 at preset time intervals.

[0062] Furthermore, after receiving the first flow rate and target water level information, the automatic control device 16 determines whether the first flow rate is greater than the preset flow rate or whether the target water level is greater than the preset water level. When the target water level is greater than the preset water level, in order to prevent the water level in the well body 10 from being too high, which would cause sewage in the well body 10 to backflow into the rainwater pipe 12, the automatic control device 16 controls the interceptor device 13 to close the second inlet 102 to prevent liquid in the well body 10 from overflowing and entering the rainwater.

[0063] Correspondingly, when the first flow rate exceeds the preset flow rate, that is, when the flow rate in the sewage pipe exceeds the threshold, sewage may still mix with rainwater if the intercepting device 13 is not controlled to close the second inlet 102. Therefore, when the first flow rate exceeds the preset flow rate, the automatic control device 16 controls the intercepting device 13 to close the second inlet 102, which can ensure that sewage and rainwater are properly separated in the intercepting well, avoiding cross-contamination and mixing, thereby preventing sewage from mixing with rainwater and affecting the normal drainage effect.

[0064] In this embodiment, the intercepting well includes: a well body, the well body including an outlet, a first inlet connected to a sewage pipe, and a second inlet connected to a rainwater pipe; an intercepting device, the intercepting device being disposed at the second inlet; a first flow sensor, the first flow sensor being disposed inside the sewage pipe for collecting the first flow rate of the sewage pipe; a target liquid level sensor, disposed inside the well body for detecting the target water level information of the well body; and an automatic control device, the automatic control device being connected to both the target liquid level sensor and the first flow sensor, for controlling the intercepting device to close the second inlet if the first flow rate is greater than a preset flow rate or the target water level information is greater than a preset water level. This embodiment monitors the target water level information inside the well body using the target liquid level sensor, and monitors the first flow rate of the sewage pipe using the first flow sensor. This allows for timely detection of changes in rainwater inside the well body and sewage in the sewage pipe. When the first flow rate is greater than a preset flow rate or the target water level information is greater than a preset water level, the intercepting device is controlled to close the second inlet, preventing sewage from mixing with rainwater, thereby effectively controlling the discharge of rainwater and sewage.

[0065] This application provides a second embodiment of a diversion well, referring to... Figure 3 , Figure 3 A schematic diagram of the structure of a second embodiment of the intercepting well of this application is shown.

[0066] In this embodiment, the intercepting well further includes:

[0067] A first liquid level sensor 17 is installed inside the sewage pipe 11 and is connected to the automatic control device 16 to collect the first water level information of the sewage pipe 11.

[0068] The second liquid level sensor 18 is installed inside the rainwater pipe 12. The first liquid level sensor 18 is connected to the automatic control device 16 and is used to collect the second water level information inside the rainwater pipe 12.

[0069] The automatic control device 16 is also used to receive the first water level information and the second water level information. If at least one of the first water level information, the second water level information, the first flow rate, or the target water level information is greater than the corresponding preset threshold, the device 16 controls the interception device 13 to close the second water inlet.

[0070] In this embodiment, refer to Figure 4 As shown, the automatic control device 16 can be connected to the first liquid level sensor 17 and the second liquid level sensor 18 respectively through wireless communication technology. The automatic control device 16 can periodically collect the first water level information of the sewage pipe 11 and the second water level information of the rainwater pipe 12 from the first liquid level sensor 17 and the second liquid level sensor according to a preset time interval.

[0071] After receiving the first water level information and the second water level information, the automatic control device 16 can determine whether the first water level information, the second water level information, the first flow rate, or the target water level information are all less than the corresponding preset threshold. When the first water level information, the second water level information, the first flow rate, or the target water level information are all less than the corresponding preset threshold, it indicates that the current drainage situation is within the normal range and no interception treatment is required. Conversely, when at least one of the first water level information, the second water level information, the first flow rate, or the target water level information is greater than the corresponding preset threshold, and the other indicators are not zero, it means that the drainage system has experienced an abnormal situation such as a sudden increase in the first flow rate of the sewage pipe 11. In this case, in order to prevent sewage from flowing into rainwater and thus affecting the environment, the automatic control device 16 needs to control the interception device 13 to close the second inlet to prevent the spread of sewage.

[0072] Understandably, in order to fully understand the real-time situation of the liquid inside the rainwater pipe 12, so as to promptly detect abnormal fluctuations or malfunctions, further, as an optional implementation method, refer to... Figure 3 As shown, the interception well also includes:

[0073] The second flow sensor 19 is disposed inside the rainwater pipe 12 and is used to collect the second flow rate of the rainwater pipe 12.

[0074] The automatic control device 16 is also used to receive the second flow rate. If at least one of the first water level information, the second water level information, the first flow rate, the second flow rate, or the target water level information is greater than the corresponding preset threshold, the device 13 is controlled to close the second inlet.

[0075] Specifically, refer to Figure 4 As shown, the second flow sensor 19 can be connected to the automatic control device 16 based on the aforementioned connection method. The automatic control device 16 can periodically collect the second flow rate in the rainwater pipe 12 collected by the second flow sensor 19 at preset intervals.

[0076] After receiving the second flow rate, the automatic control device 16 determines whether at least one of the first water level information, the second water level information, the first flow rate, the second flow rate, or the target water level information is greater than the corresponding preset threshold. When at least one of the first water level information, the second water level information, the first flow rate, the second flow rate, or the target water level information is greater than the corresponding preset threshold, and the other indicators are not 9, the automatic control device 16 needs to control the interception device 13 to close the second inlet to prevent the spread of sewage.

[0077] In this embodiment, the real-time status of the liquid in the sewage pipe 11, rainwater pipe 12, and well body 10 can be fully understood by checking whether at least one of the first water level information, second water level information, first flow rate, second flow rate, or target water level information is greater than the corresponding preset threshold. This helps to detect abnormal fluctuations in a timely manner, and thus respond to the abnormal situation when an abnormality occurs, that is, control the interception device 13 to close the second inlet 102 to prevent sewage from mixing into the rainwater.

[0078] It should be noted that when the first water level, the second water level, the first flow rate, the second flow rate, and the target water level are all less than the corresponding preset thresholds, the automatic control device 16 will not control the interception device 13 to close the second inlet 102 for interception. However, when the first water level, the second water level, the first flow rate, the second flow rate, and the target water level are all less than the corresponding preset thresholds, there may be a situation where the concentration of pollutants in the water is too high. In this case, if the automatic control device 16 does not control the interception device 13 to close the second inlet 102 for interception, the sewage with excessively high pollutant concentration will still mix into the rainwater, thereby affecting the normal drainage effect. Furthermore, this application provides a third embodiment of the interception well, referring to... Figure 5 , Figure 5 A structural schematic diagram of the third embodiment of the intercepting well of this application is shown.

[0079] In this embodiment, the intercepting well further includes:

[0080] A first water quality sensor 20 is installed inside the sewage pipe 11 and is connected to the automatic control device 16. It is used to collect the first pH value or the first BOD concentration value inside the sewage pipe 11.

[0081] The second water quality sensor 21 is installed inside the rainwater pipe 12. The second water quality sensor 21 is connected to the automatic control device 16 and is used to collect the second pH value or the second BOD concentration value inside the rainwater pipe 12.

[0082] The third water quality sensor 22 is installed inside the well body 10 and is connected to the automatic control device 16. It is used to collect the third pH value or the third BOD concentration value inside the well body 10.

[0083] The automatic control device 16 is further configured to receive a first pH value or a first BOD concentration value, a second pH value or a second BOD concentration value, and a third pH value or a third BOD concentration value. If at least one of the first water level information, the second water level information, the first flow rate, the second flow rate, the first pH value or the first BOD concentration value, the second pH value or the second BOD concentration value, the third pH value or the third BOD concentration value, or the target water level information is greater than the corresponding preset threshold, then the intercepting device 13 is controlled to close the second water inlet.

[0084] In this embodiment, the first water quality sensor 20, the second water quality sensor 21, and the third water quality sensor 23 can be used to monitor and measure the concentrations of various chemical substances, microorganisms, and other pollutants in the water, such as the pH value and BOD (Biochemical Oxygen Demand) concentration.

[0085] Understandably, when the pH level of water is too high or too low, it disrupts the ecological balance of the water body and causes some dissolved substances in the water to precipitate out, forming solid particles and reducing water quality. When the BOD concentration of water is too high, it leads to eutrophication, promotes the reproduction of algae and bacteria, and disrupts the balance of the aquatic ecosystem.

[0086] Therefore, in order to avoid disrupting the aquatic ecological balance, refer to Figure 6As shown, the first water quality sensor 20, the second water quality sensor 21, and the third water quality sensor 22 can all be connected to the automatic control device 16 via wireless communication technology. After the automatic control device 16 is connected to the first water quality sensor 20, the second water quality sensor 21, and the third water quality sensor 22, the automatic control device 16 can periodically collect the first pH value or the first BOD concentration value of the sewage pipe 11 collected by the first water quality sensor 20, the second pH value or the second BOD concentration value of the rainwater pipe 12 collected by the second water quality sensor 21, and the third pH value or the third BOD concentration value of the well body collected by the third water quality sensor at preset time intervals. When at least one of the first pH value or the first BOD concentration value, the second pH value or the second BOD concentration value, the third pH value or the third BOD concentration value, the first water level information, the second water level information, the first flow rate, the second flow rate, or the target water level information is greater than the corresponding preset threshold, the automatic control device 16 controls the interception device 13 to close the second inlet 102.

[0087] In this embodiment, the liquid level, flow rate, and pollutant concentration are considered together to determine whether to control the interception device 13 to close the second inlet 102. This can prevent the drainage system from having high concentrations of pollutants in the sewage or a sudden increase in flow rate, thereby preventing sewage from mixing with rainwater.

[0088] This application provides a fourth embodiment of a diversion well, referring to... Figure 7 , Figure 7 A structural schematic diagram of the fourth embodiment of the intercepting well of this application is shown.

[0089] In this embodiment, the intercepting well further includes:

[0090] Rainfall sensor 23 is disposed on the surface of the well body 10 and is connected to the automatic control device 16 for collecting rainfall data.

[0091] The automatic control device 16 is also used to receive the rainfall and, based on the rainfall, predict future rainfall using a rainfall forecasting model;

[0092] The automatic control device 16 is also used to input the future rainfall into the rainfall runoff network model to obtain the rainfall runoff change output by the network model, and input the rainfall runoff change, the first water level information, the second water level information, the first flow rate, the second flow rate, the first pH value or the first BOD concentration value, the second pH value or the second BOD concentration value, the third pH value or the third BOD concentration value, and the target water level information into the interception control model to obtain the interception duration output by the interception control model;

[0093] The automatic control device 16 is also used to obtain the closing duration of the second inlet 102 based on the interception duration, and control the opening and closing of the interception device 13 based on the closing duration.

[0094] Specifically, refer to Figure 8 As shown, the rainfall sensor 23 can be connected to the automatic control device 16 via wireless communication technology. After receiving the rainfall data collected by the rainfall sensor, the automatic control device 16 can input the rainfall data into the rainfall forecast model to obtain the predicted future rainfall output by the rainfall forecast model.

[0095] Furthermore, after obtaining the future rainfall amount output by the rainfall forecast model, the automatic control device 16 can input the future rainfall amount into the rainfall runoff network model to obtain the rainfall runoff change output by the rainfall runoff network model. After obtaining the rainfall runoff change, a watershed model can be established using urban drainage system simulation software (such as SWMM, EPANET, etc.), inputting rainfall data and related parameters, such as rainfall runoff change, to simulate the formation and flow process of runoff, thereby obtaining the flow rate entering the interception well.

[0096] After obtaining the flow rate result, the flow rate result, the first pH value or first BOD concentration value, the second pH value or second BOD concentration value, and the third pH value or third BOD concentration value can be sent to the automatic control device 16. When the first pH value or first BOD concentration value, the second pH value or second BOD concentration value, the third pH value or third BOD concentration value, the first water level information, the second water level information, the first flow rate, the second flow rate, and the target water level information are input into the interception control model, the interception duration output by the interception control model is obtained. Based on the interception duration, the automatic control device 16 obtains the closing duration of the second inlet 102, and controls the opening and closing of the interception device 13 based on the closing duration. That is, the interception duration is used as the closing duration of the second inlet 102, and the opening and closing of the interception device 13 is controlled based on the closing duration.

[0097] It should be noted that when the automatic control device 16 inputs the first pH value or first BOD concentration value, the second pH value or second BOD concentration value, the third pH value or third BOD concentration value, the first water level information, the second water level information, the first flow rate, the second flow rate, and the target water level information into the interception control model to obtain the interception duration output by the interception control model, in order to ensure calculation accuracy and efficiency, as an optional implementation, the automatic control device 16 is further used to input the rainfall-runoff change, the first water level information, the second water level information, the first flow rate, the second flow rate, the first pH value or first BOD concentration value, the second pH value or second BOD concentration value, the third pH value or third BOD concentration value, and the target water level information into the interception control model, so that the interception control model outputs the interception duration according to a preset simulation step size; and controls the opening and closing of the interception device 13 based on the interception duration.

[0098] In this embodiment, the simulation step size can be the interval at which the interception control model calculates the interception duration using a first pH value or a first BOD concentration value, a second pH value or a second BOD concentration value, a third pH value or a third BOD concentration value, first water level information, second water level information, first flow rate, second flow rate, and the target water level information. For example, when the preset simulation step size is 60 seconds, the interception control model uses the above parameters to perform a calculation every 60 seconds.

[0099] Furthermore, after obtaining the future rainfall, in order to avoid the liquid overflowing from the interception well 10 due to excessive future rainfall, or the rainwater not being effectively intercepted due to insufficient future rainfall, the automatic control device 16 is further used to input the future rainfall and the target water level information into the interception control model to obtain the predicted well water level information output by the interception control model.

[0100] The automatic control device 16 is also used to control the opening and closing of the interception device 13 based on the predicted well water level information.

[0101] Specifically, after obtaining the future rainfall, the automatic control device 16 can obtain the flow rate of rainwater entering the interception well based on the aforementioned operation, input the flow rate result and target water level information into the interception control model, and the interception control model calculates based on the flow rate result and target water level information, and outputs the predicted well water level information.

[0102] Furthermore, after obtaining the predicted well water level information, the automatic control device 16 compares the predicted well water level information with the target water level information, and controls the opening and closing of the interception device 13 based on the comparison result.

[0103] It is understandable that when the automatic control device 16 controls the intercepting device 13 to close the second inlet 102, in order to prevent the liquid in the well body 10 from overflowing and to effectively intercept rainwater, it is also necessary to determine the opening degree of the intercepting device 13. Therefore, further, as an optional implementation, the automatic control device 16 is also used to use a fuzzy control algorithm to analyze at least one of the first water level information, the second water level information, the first flow rate, the second flow rate, the first pH value or the first BOD concentration value, the second pH value or the second BOD concentration value, the third pH value or the third BOD concentration value, or the target water level information to obtain water flow parameters, and adjust the opening degree of the intercepting device 13 based on the water flow parameters.

[0104] Specifically, after receiving the first pH value or first BOD concentration value, the second pH value or second BOD concentration value, and the third pH value or third BOD concentration value, the automatic control device 16 can perform fuzzification processing on at least one of the following: the first pH value or first BOD concentration value, the second pH value or second BOD concentration value, the third pH value or third BOD concentration value, the first water level information, the second water level information, the first flow rate, the second flow rate, and the target water level information, to obtain fuzzy variables, that is, mapping specific numerical values ​​onto fuzzy sets. After obtaining the fuzzy variables, fuzzy inference is performed using the fuzzy variables and fuzzy rules to obtain fuzzy output results, and the fuzzy output results are converted into specific output values, i.e., water flow parameters, and the opening degree of the intercepting device 13 is adjusted according to the water flow parameters.

[0105] In this embodiment, the automatic control device controls the opening degree and closing time of the interception device based on the collected parameters, thereby automatically and effectively intercepting and discharging rainwater, sewage, etc.

[0106] This application provides a fifth embodiment of a diversion well, referring to... Figure 9 , Figure 9 A structural schematic diagram of the fifth embodiment of the intercepting well of this application is shown.

[0107] In this embodiment, the intercepting well further includes:

[0108] Discharge device 24, which is connected to the outlet 103.

[0109] In this embodiment, the discharge device 24 can be a device or structure for discharging liquid from the well body 10 to a sewer system or sewage treatment system. The automatic control device 16 is communicatively connected to the discharge device 24, as shown in the following figure. Figure 10 As shown, the discharge device 24 can open or close the valve under the control of the automatic control device 16.

[0110] Specifically, the discharge device 24 is connected to the outlet 101 of the well body 10. When the water level in the well body 10 exceeds the maximum storage water level, in order to prevent the liquid in the well body 10 from overflowing, the automatic control device 16 controls the valve of the discharge device 24 to open and discharge the liquid in the well body 10 to the sewer system or sewage treatment system.

[0111] In this embodiment, the discharge device 24 is connected to the outlet 103 of the well body 10. When the water level in the well body exceeds the maximum storage water level, the liquid in the well body 10 can be discharged to the sewer system or sewage treatment facility. By discharging the rainwater and sewage in the well body to a designated location, the problem of random discharge of rainwater and sewage can be effectively prevented, thereby avoiding the overflow of liquid in the well body 10 and effectively reducing the cost of sewage treatment.

[0112] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
