In urban planning and environmental protection, the drainage and disposal of rainwater and sewage is an important issue. Conventional stormwater drainage systems typically include storm water lines and wells, but these facilities often fail to effectively intercept and drain stormwater, particularly in heavy or heavy rain conditions. Therefore, in order to solve the problem of rainwater interception and drainage, the intercepting well is mainly used for intercepting and drainage of rainwater.
The intercepting well is a water-spreading facility for intensively treating rainwater and sewage. The traditional intercepting well is formed by pouring reinforced concrete, a blocking partition wall (overflow weir) is additionally arranged in the intercepting well, one side of the wall is connected with a converging pipe for receiving incoming water, and meanwhile, the intercepting well is connected with a sewage pipe; an overflow pipe is connected to the other side of the wall, and the overflow pipe is connected with a rainwater pipeline to send overflowed water into a river channel.
However, the conventional intercepting well cannot prevent sewage from being mixed with rainwater.
The application provides a solution, this application embodiment monitors the internal target water level information of well through target level sensor, and first flow sensor monitors the first flow of monitoring sewer line, can in time discover the internal rainwater of well and the change of sewage in the sewer line to when first flow is greater than preset flow or target water level information is greater than preset water level, control stop closes the second water inlet, can avoid sewage to mix in the rainwater, thereby control the discharge of rainwater and sewage effectively.
The following description will be made of a vatch basin applied in the implementation of the technology of the present application:
the present application provides a first embodiment of a shut-in well, and referring to fig. 1, fig. 1 is a schematic structural view of the first embodiment of a shut-in well of the present application, the shut-in well comprising:
a well 10 comprising a water outlet 103, a first water inlet 101 in communication with a sewer line 11 and a second water inlet 102 in communication with a sewer line 12;
a cut-off device 13, wherein the cut-off device 13 is arranged at the second water inlet 102;
a first flow sensor 14, the first flow sensor 14 being arranged in the sewer line 11 for collecting a first flow of the sewer line 11;
a target liquid level sensor 15, disposed in the well body 10, for detecting target water level information of the well body 10;
and the automatic control device 16 is connected with the target liquid level sensor 15 and the first flow sensor 14, and is used for controlling the cut-off device 13 to close the second water inlet 102 if the first flow is greater than a preset flow or the target water level information is greater than a preset water level.
In this embodiment, the intercepting well is a type of intercepting facility commonly used in urban drainage systems for collecting and intercepting rainwater and sewage to relieve the pressure of the drainage system.
The well body 10 of the intercepting well is provided with a first water inlet 101 and a second water inlet 102, the first water inlet 101 is connected with a sewage pipeline 11, the second water inlet 102 is connected with a rainwater pipeline 12, rainwater and sewage generated during rainfall can enter the well body 10 through the rainwater pipeline 102 and the sewage pipeline 11 respectively, the well body 10 has a certain volume, a part of rainwater and sewage can be intercepted, and a mixture of the sewage and the rainwater is gradually discharged into a drainage system through a water outlet 103 when needed, so that the load of the drainage system is smoothed, and the impact of the rainfall flood on the drainage system is reduced. The automatic control device 16 may be a processor with data acquisition, analysis and processing functions.
Specifically, referring to fig. 2, the automatic control device 16 may be connected to the first flow sensor 14, the target level sensor 15, and the stop 13 by wireless connection technology. After the automatic control device 16 is connected with the first flow sensor 14 and the target liquid level sensor, the automatic control device 16 can periodically collect the first flow 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 according to a preset time interval.
Further, the automatic control device 16 determines whether the first flow rate is greater than a preset flow rate or whether the target water level information is greater than a preset water level after receiving the first flow rate and the target water level information. When the target water level information is greater than the preset water level, in order to avoid the water level in the well body 10 being too high, so that sewage in the well body 10 flows backward through the rainwater pipeline 12, the automatic control device 16 controls the cut-off device 13 to close the second water inlet 102, so as to avoid the overflow of the liquid in the well body 10 and enter the rainwater.
Accordingly, when the first flow rate is greater than the preset flow rate, that is, the flow rate in the sewage pipe exceeds the threshold value, the sewage may still be mixed into the rainwater if the cut-off device 13 is not controlled to close the second water inlet 102. Therefore, when the first flow is greater than the preset flow, the automatic control device 16 controls the stop device 13 to close the second water inlet 102, so that the sewage and the rainwater can be properly split in the stop well, cross contamination and mixing are avoided, the sewage is prevented from being mixed into the rainwater, and the normal drainage effect is further affected.
In this embodiment, the intercepting well includes: the well body comprises a water outlet, a first water inlet communicated with the sewage pipeline and a second water inlet communicated with the rainwater pipeline; the cut-off device is arranged at the second water inlet; a first flow sensor arranged in the sewage pipeline and used for collecting a first flow of the sewage pipeline; the target liquid level sensor is arranged in the well body and used for detecting target water level information of the well body; and the automatic control device is connected with the target liquid level sensor and the first flow sensor and is used for controlling the cut-off device to close the second water inlet if the first flow is larger than the preset flow or the target water level information is larger than the preset water level. According to the embodiment, the target water level information in the well body is monitored through the target liquid level sensor, the first flow sensor monitors the first flow of the sewage pipeline, the change of rainwater in the well body and sewage in the sewage pipeline can be found timely, when the first flow is larger than the preset flow or the target water level information is larger than the preset water level, the second water inlet is closed by the control cut-off device, sewage can be prevented from being mixed into the rainwater, and accordingly the discharge of the rainwater and the sewage can be effectively controlled.
The present application provides a second embodiment of a shut-in well, and referring to fig. 3, fig. 3 shows a schematic structural view of the second embodiment of a shut-in well of the present application.
In this embodiment, the intercepting well further includes:
a first liquid level sensor 17, wherein the first liquid level sensor 17 is arranged in the sewage pipeline 11, and the first liquid level sensor 17 is connected with the automatic control device 16 and is used for collecting first water level information of the sewage pipeline 11;
a second liquid level sensor 18, wherein the second liquid level sensor 18 is disposed in the rainwater pipeline 12, and the first liquid level sensor 18 is connected with the automatic control device 16 and is used for collecting second water level information in the rainwater pipeline 12;
the automatic control device 16 is further configured to receive the first water level information and the second water level information, and 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 a corresponding preset threshold, control the cut-off device 13 to close the second water inlet.
In this embodiment, referring to fig. 4, the automatic control device 16 may be connected to the first liquid level sensor 17 and the second liquid level sensor 18 through wireless communication technology, and the automatic control device 16 may periodically collect the first liquid level information of the sewage pipe 11 and the second liquid level information of the rainwater pipe 12 according to a preset interval period.
After receiving the first water level information and the second water level information, the automatic control device 16 may determine whether the first water level information, the second water level information, the first flow rate, or the target water level information are all smaller than the corresponding preset threshold. When the first water level information, the second water level information, the first flow or the target water level information are smaller than the corresponding preset threshold values, the current drainage condition is in the normal range, and the interception treatment is not needed. Accordingly, 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 value, and the other indexes are not 0, this means that the drainage system has abnormal situations such as sudden increase of the first flow rate of the sewage pipeline 11. In this case, however, in order to prevent the sewage from flowing into the rainwater, thereby affecting the environment, the automatic control device 16 needs to control the shut-off device 13 to close the second water inlet to prevent the diffusion of the sewage.
It will be appreciated that, in order to fully understand the real-time condition of the liquid in the rainwater pipeline 12 so as to find abnormal fluctuations or faults in time, further, as an alternative embodiment, referring to fig. 3, the intercepting well further includes:
a second flow sensor 19, where the second flow sensor 19 is disposed in the rainwater pipeline 12 and is used for collecting a second flow of the rainwater pipeline 12;
the automatic control device 16 is further configured to receive the second flow rate, and 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 a corresponding preset threshold, control the cut-off device 13 to close the second water inlet.
Specifically, referring to fig. 4, the second flow sensor 19 may be connected to the automatic control device 16 based on the foregoing connection manner, and the automatic control device 16 may periodically collect the second flow in the rainwater pipeline 12 collected by the second flow sensor 19 at preset intervals.
After the automatic control device 16 receives the second flow, the automatic control device 16 determines whether at least one of the first water level information, the second water level information, the first flow, the second flow or the target water level information is greater than a corresponding preset threshold, and when at least one of the first water level information, the second water level information, the first flow, the second flow or the target water level information is greater than the corresponding preset threshold and the other indexes are not 9, the automatic control device 16 needs to control the cut-off device 13 to close the second water inlet at this time so as to prevent the diffusion of sewage.
In this embodiment, 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 a corresponding preset threshold value can be determined, and when 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 determined, the real-time situation of the sewage pipeline 11, the rainwater pipeline 12, and the liquid in the well body 10 can be comprehensively known, so that abnormal fluctuation can be found in time, and when abnormality occurs, the abnormal situation is responded, that is, the control cut-off device 13 closes the second water inlet 102, so as to avoid sewage from being mixed into rainwater.
It should be noted that, when 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 all smaller than the corresponding preset threshold values, the automatic control device 16 will not control the shutoff device 13 to close the second water inlet 102 for the shutoff operation. However, when 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 all smaller than the corresponding preset threshold values, there may be a situation that the concentration of the pollutants in the water is too high at this time, and in this case, if the automatic control device 16 does not control the shut-off device 13 to close the second water inlet 102 for performing the shut-off operation, the sewage with the too high concentration of the pollutants still mixes into the rainwater, so as to affect the normal drainage effect.
In this embodiment, the intercepting well further includes:
a first water quality sensor 20, wherein the first water quality sensor 20 is arranged in the sewage pipeline 11, and the first water quality sensor 20 is connected with the automatic control device 16 and is used for collecting a first PH value or a first BOD concentration value in the sewage pipeline 11;
a second water quality sensor 21, wherein the second water quality sensor 21 is arranged in the rainwater pipeline 12, and the second water quality sensor 21 is connected with the automatic control device 16 and is used for collecting a second PH value or a second BOD concentration value in the rainwater pipeline 12;
a third water quality sensor 22, wherein the third water quality sensor 22 is arranged in the well body 10, and the third water quality sensor 22 is connected with the automatic control device 16 and is used for collecting a third PH value or a third BOD concentration value in the well body 10;
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, and if at least one of the first water level information, the second water level information, the first flow, the second flow, 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 a corresponding preset threshold value, control the shutoff device 13 to close the second water inlet.
In this embodiment, the first, second and third water quality sensors 20, 21 and 23 may be used to monitor and measure various chemical, microbiological and other contaminant concentrations in water, such as PH, BOD (Biochemical Oxygen Demand ) concentrations, etc.
It is understood that when the PH of the water is too high or too low, the ecological balance in the water is destroyed and some of the dissolved substances in the water are caused to precipitate out, forming solid particles, reducing the quality of the water. When the BOD concentration of the water is too high, the water can be eutrophicated, the propagation of algae and bacteria is promoted, and the balance of an aquatic ecosystem is destroyed.
Therefore, in order to avoid the disruption of the water ecological balance, referring to fig. 6, the first water quality sensor 20, the second water quality sensor 21, and the third water quality sensor 22 may be connected to the automatic control device 16 by wireless communication technology. After the automatic control device 16 is connected with 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 pipeline 11 collected by the first water quality sensor 20, the second PH value or the second BOD concentration value of the rainwater pipeline 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 according to a preset time interval. 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, the second flow, or the target water level information is greater than a corresponding preset threshold, the automatic control device 16 controls the shutoff device 13 to close the second water inlet 102.
In this embodiment, three indexes, i.e., the liquid level, the flow rate and the pollutant concentration, are comprehensively considered, so that whether the cut-off device 13 is controlled to close the second water inlet 102 is determined, and the situation that the sewage in the drainage system contains high-concentration pollutants or the flow rate suddenly increases can be avoided, so that the sewage is prevented from being mixed into rainwater.

the automatic control device 16 is further configured to obtain a closing time period of the second water inlet 102 based on the shutoff time period, and control the shutoff device 13 to open and close based on the closing time period.
Specifically, referring to fig. 8, the rainfall sensor 23 may be connected to the automatic control device 16 through a wireless communication technology, and after receiving the rainfall collected by the rainfall sensor, the automatic control device 16 may input the rainfall into the rainfall prediction model to obtain the predicted future rainfall output by the rainfall prediction model.
Further, after obtaining the future rainfall output by the rainfall prediction model, the automatic control device 16 may input the future rainfall into the rainfall runoff pipe network model to obtain the rainfall runoff variation output by the rainfall runoff pipe network model. After obtaining the rainfall runoff change, urban drainage system simulation software (such as SWMM, EPANET and the like) can be utilized to establish a river basin model, rainfall data and related parameters such as rainfall runoff change are input, and the formation and flow process of the runoff is simulated, so that a flow result entering a intercepting well is obtained.
After the flow result is obtained, the flow result, the first PH or the first BOD concentration value, the second PH or the second BOD concentration value, and the third PH or the third BOD concentration value may be sent to the automatic control device 16. When 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, the second flow and the target water level information are input into the interception regulation model, the interception duration output by the interception regulation model is obtained. The automatic control device 16 obtains the closing time length of the second water inlet 102 based on the closing time length, controls the opening and closing of the shutoff device 13 based on the closing time length, namely, the closing time length of the second water inlet 102 is taken as the closing time length, and controls the opening and closing of the shutoff device 13 based on the closing time length.

For example, when the preset simulation step length is 60 seconds, the interception regulation model uses the parameters to calculate every 60 seconds.
Further, after the future rainfall is obtained, the automatic control device 16 is further configured to input the future rainfall and the target water level information into a intercepting regulation model to obtain predicted well water level information output by the intercepting regulation model, so as to avoid overflow of the liquid in the intercepting well body 10 caused by the excessive future rainfall or incapability of effectively intercepting rainwater due to the insufficient future rainfall;
the automatic control device 16 is further used for controlling the cut-off device 13 to be opened and closed based on the predicted well water level information.
Specifically, after obtaining the future rainfall, the automatic control device 16 may obtain a flow result of the rainwater entering the intercepting well based on the foregoing operation, input the flow result and the target water level information into the intercepting regulation model, calculate the intercepting regulation model based on the flow result and the target water level information, and output the pre-logging water level information.
Further, the automatic control device 16 compares the predicted well water level information with the target water level information after obtaining the predicted well water level information, and controls the opening and closing of the cut-off device 13 according to the comparison result.
It will be appreciated that when the automatic control device 16 controls the stop device 13 to close the second water inlet 102, in order to prevent the liquid in the well body 10 from overflowing and effectively stop rainwater, the opening of the stop device 13 needs to be determined, so further, as an alternative implementation, the automatic control device 16 is further configured 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 by using a fuzzy control algorithm, obtain a water flow parameter, and adjust the opening of the stop device 13 based on the water flow parameter.
Specifically, after the automatic control device 16 receives the first PH value or the first BOD concentration value, the second PH value or the second BOD concentration value, and the third PH value or the third BOD concentration value is sent to the automatic control device 16, the automatic control device 16 may perform the blurring process on 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, the second flow, and the target water level information, to obtain a blurring variable, that is, map a specific numerical value onto the blurring set. After the fuzzy variable is obtained, fuzzy reasoning is carried out by utilizing the fuzzy variable and a fuzzy rule to obtain a fuzzy output result, the fuzzy output result is converted into a specific output value, namely a water flow parameter, and the opening degree of the cut-off device 13 is adjusted according to the water flow parameter.
In this embodiment, the automatic control device controls the opening degree and closing time of the intercepting device according to the collected parameters, so that rainwater, sewage and the like can be intercepted and discharged automatically and effectively.

The automatic control device 16 is in communication with a drain 24. Referring to fig. 10, the drain 24 can open or close a valve under the control of the automatic control device 16.
Specifically, the drain device 24 is connected to the water outlet 101 of the well body 10, when the water level of the liquid in the well body 10 exceeds the maximum storage water level, in order to avoid overflow of the liquid in the well body 10, the automatic control device 16 controls the valve of the drain device 24 to be opened at this time, so as to drain the liquid in the well body 10 to the sewer system or the sewage treatment system.
In this embodiment, the drainage device 24 is connected to the water outlet 103 of the well body 10, so that when the water level of the liquid in the well body exceeds the maximum storage water level, the liquid in the well body 10 can be drained to a sewer system or a sewage treatment facility, and by draining the rainwater and sewage in the well body to a designated position, the problem of random drainage of the rainwater and sewage can be effectively prevented, so that the overflow of the liquid in the well body 10 is avoided, and the cost of sewage treatment can be effectively reduced.
