Description

Technical Field

[0001] The present invention relates to the technical field of pressure self-regulation, and particularly to a self-regulating control system for the cleaning pressure of a delivery pump. Background Art

[0002] A delivery pump is needed during the sewage discharge process in a pool. The delivery pump can accelerate the sewage discharge speed and improve the sewage discharge efficiency. However, during sewage discharge, there are many impurities in the water that easily block the delivery pump, resulting in damage to the delivery pump. Therefore, it is necessary to clean the delivery pump in real time during sewage discharge to avoid blockage of the delivery pump. When the sewage discharge is smooth, no cleaning is required. However, when the sewage is almost discharged, the sludge at the bottom of the pool is sucked into the delivery pump, and the flow rate of the sewage in the delivery pump significantly slows down.

[0003] The existing cleaning devices cannot intelligently adjust the pressure when cleaning the inside of the delivery pump, resulting in an impact on the cleaning effect. Moreover, during the cleaning process, the pressure cannot be adjusted according to the turbidity of the water quality, affecting the sewage discharge efficiency. Therefore, it is necessary to design a self-regulating control system for the cleaning pressure of a delivery pump that can intelligently adjust the pressure. Summary of the Invention

[0004] The purpose of the present invention is to provide a self-regulating control system for the cleaning pressure of a delivery pump to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A self-regulating control system for the cleaning pressure of a delivery pump, comprising a cleaning device and an intelligent regulation system, characterized in that: the cleaning device includes a chassis, a cleaning pump is fixedly installed above the chassis, the cleaning pump is connected to an external clean water pipeline, a pipeline on the left side of the cleaning pump is connected to a delivery pump, the delivery pump is connected to an external sewage pipeline, a water quality detector is fixedly installed inside the delivery pump, a pipeline above the cleaning pump is connected to a pressure pump, the right side of the pressure pump is connected to an external cleaning agent pipeline, a bracket is fixedly installed above the right side of the chassis, a controller is fixedly installed on the left side of the upper end of the bracket, an indicator light is fixedly installed on the surface of the controller, and the intelligent regulation system is electrically connected to the controller, the indicator light, the cleaning pump, the delivery pump, the water quality detector, the cleaning pump, and the pressure pump respectively.

[0006] According to the above technical solution, a rotating cavity is fixedly installed in the middle of the delivery pump, a motor is fixedly installed above the rotating cavity, a flow rate detector is connected to a pipeline on the rear side of the right side of the delivery pump, the flow rate detector is connected to an external sewage pipeline, and the intelligent regulation system is electrically connected to the motor and the flow rate detector respectively.

[0007] According to the above technical solution, the intelligent adjustment system includes a detection module, a processing module, a data transmission module, a data receiving module, a calculation module, and a control module. The detection module is electrically connected to a water quality detector, a flow meter, and the data transmission module respectively. The data receiving module is electrically connected to the calculation module and the data transmission module respectively. The calculation module is electrically connected to the control module. The control module is electrically connected to a cleaning pump and a delivery pump;

[0008] The detection module is used to detect the water quality of the sewage through the water quality detector, convert the detected water quality data into the degree of water quality turbidity, and collect the data. The detection module is used to measure the flow rate of the sewage entering the delivery pump through the flow meter, convert the detected flow rate data into the degree of flow rate, and collect the data. The processing module is used to assist in controlling the device according to the data detected. The data transmission module is used to transmit the detected data. The data receiving module is used to receive the transmitted data. The calculation module is used to automatically calculate the result through the received data. The control module is used to control the cleaning pump and the delivery pump respectively according to the calculated result.

[0009] According to the above technical solution, the processing module includes a data collection module, a conversion module, and a driving module. The data collection module is electrically connected to the detection module. The data collection module is electrically connected to the conversion module. The conversion module is electrically connected to the driving module. The driving module is electrically connected to the cleaning pump, the delivery pump, a pressure pump, a motor, and an indicator light;

[0010] The data collection module is used to collect the data according to the degree of water quality turbidity and the degree of sewage flow rate detected by the detection module. The conversion module is used to convert the collected data to obtain the driving data for the subsequent structure. The driving module is used to control the operating modes of the cleaning pump, the delivery pump, the pressure pump, the motor, and the indicator light according to the converted result.

[0011] According to the above technical solution, the intelligent adjustment system includes the following operating steps:

[0012] S1. The operator turns on the controller, and the controller drives the intelligent adjustment system to operate electrically. The intelligent adjustment system drives the delivery pump to operate electrically, and the delivery pump conveys the sewage;

[0013] S2. The intelligent adjustment system controls the water quality detector to operate electrically. The water quality detector detects the water quality of the sewage, converts the detected water quality data into the degree of water quality turbidity, measures the flow rate of the sewage through the flow meter, and obtains the degree of sewage flow rate. The sewage flow rate affects the size of the turbidity during water quality detection. Among them, R 检R is the turbidity of the sewage detected by the water quality detector 设 R is the set sewage turbidity in the thermometer, and R is the real-time turbidity of the sewage 系 is the change amount of the water quality turbidity under the sewage flow rate of a single unit, V is the real-time flow rate of the sewage, and at the same time, the flow rate of the sewage entering the transfer pump is measured by the flow meter wherein, V 检 is the sewage flow rate detected by the flow meter, V 设 is the set flow rate in the flow meter. When the real-time flow rate of the sewage is greater than 100%, it means that the sewage is discharged smoothly and no cleaning is required. When the real-time flow rate of the sewage is less than 100%, it means that the sludge in the sewage accumulates in the transfer pump and needs to be cleaned. The two obtained data are transmitted to the data transmission module and the data collection module

[0014] S3. The data transmission module then transmits the data out. The transmitted data is received by the data receiving module, and the received data is transmitted from the data receiving module to the calculation module through electrical transmission. The calculation module automatically calculates the obtained data to obtain the result and inputs the result into the control module

[0015] S4. The control module drives the cleaning pump to operate according to the water quality turbidity, controls the water pressure when the cleaning pump injects clean water into the transfer pump, thereby changing the cleaning intensity, and at the same time changes the operation mode of the cleaning pump to make the cleaning pump operate intermittently. The intermittent operation time of the cleaning pump is changed according to the water quality turbidity, and the mutual operating power of the transfer pump and the cleaning pump is controlled according to the sewage flow rate. After the water quality turbidity is greater than the system set value, it enters S9, otherwise it enters S5

[0016] S5. At the same time, the data collection module collects the data and transmits the data into the conversion module. The conversion module converts the data to obtain the result and inputs the result into the drive module

[0017] S6. The drive module changes the operation mode of the cleaning pump again according to the sewage flow rate. The flow rate affects the residence time of impurities in the water in the transfer pump. According to the flow rate and the water quality turbidity, the water pressure of the cleaning pump and the intermittent time of the intermittent operation are changed

[0018] S7. The drive module drives the pressure pump to operate, changes the cleaning agent dosage discharged by the pressure pump into the cleaning pump according to the sewage flow rate. At the same time, the greater the water pressure of the clean water injected by the cleaning pump into the transfer pump, the greater the pressure of the pressure pump discharging the cleaning agent, so that the clean water and the cleaning agent can be fused with each other. When the flow rate is less than the system set value, it enters S8, otherwise it enters S10

[0019] S8. The drive module drives the motor to operate and changes the motor operating power according to the flow rate. The motor drives the rotating cavity to rotate, thereby changing the rotation speed of the rotating cavity. At the same time, the drive motor operates alternately, causing the rotating cavity to rotate alternately, and changes the alternating rotation frequency according to the flow rate. Then it enters S;

[0020] S9. At this time, the drive module controls the lighting mode of the indicator light to change through electric drive. The indicator light changes from green to red. At the same time, the drive intelligent regulation system stops operating and performs an emergency stop;

[0021] S10. After the sewage transportation is completed, the controller is turned off and the intelligent regulation system stops operating. If the sewage transportation work continues, it returns to S1.

[0022] According to the above technical solution, in S1 to S4, the water quality detector analyzes and calculates the turbidity of the sewage. Then, according to the water quality turbidity obtained after analysis, the cleaning pump is driven to operate, and the mutual operating powers of the delivery pump and the cleaning pump are controlled according to the sewage flow velocity. Among them, P 清 is the operating power of the cleaning pump, P 输 is the operating power of the delivery pump. The more turbid the water quality, the greater the operating power of the cleaning pump. At the same time, the more viscous the sewage and the slower the flow rate, which further increases the flushing intensity of the cleaning pump. When 70% < R ≤ 90%, it indicates that the water quality turbidity is relatively large. At this time, the control module drives the cleaning pump to inject clean water with a relatively large pressure, and the intermittent time of driving the cleaning pump to operate intermittently is shorter, for high-frequency flushing work. When 50% < R ≤ 70%, it indicates that the water quality turbidity is relatively normal. At this time, the control module drives the cleaning pump to inject clean water with a relatively normal pressure, and the intermittent time of driving the cleaning pump to operate intermittently is more normal, for normal-frequency flushing work. When 30% < R ≤ 50%, it indicates that the water quality turbidity is relatively small. At this time, the control module drives the cleaning pump to inject clean water with a relatively small pressure, and the intermittent time of driving the cleaning pump to operate intermittently is longer, for low-frequency flushing work.

[0023] According to the above technical solution, in S2 and S6, T 泵 = R 2 * T 系 where R 变 is the change magnitude of the water quality turbidity, T 系 is the intermittent time magnitude of the cleaning pump operation under a single unit of water quality turbidity, and T 泵Regarding the intermittent operation time of the cleaning pump, the driving module controls the cleaning pump to operate at high power, enabling the clean water to perform a stronger flushing. At the same time, the intermittent time of the cleaning pump flushing changes to a large extent. When 70% < V ≤ 90%, it indicates that the sewage flow rate is relatively large and the sewage is relatively dilute, and impurities in the water are not easily adhered to the transfer pump. At this time, the driving module controls the cleaning pump to significantly increase the original intermittent operation time. When 50% < V ≤ 70%, it indicates that the sewage flow rate is normal. At this time, the driving module controls the cleaning pump to increase the original intermittent operation time by a normal margin. When 30% < V ≤ 50%, it indicates that the sewage flow rate is relatively small and the sewage is relatively viscous, and impurities in the water are more likely to adhere to the transfer pump. At this time, the driving module controls the cleaning pump to slightly increase the original intermittent operation time.

[0024] According to the above technical solution, in S7, the driving module drives the pressure pump to operate, changes the amount of cleaning agent discharged by the pressure pump into the cleaning pump according to the speed of the sewage flow, and at the same time, the water pressure of the clean water injected into the transfer pump by the cleaning pump affects the pressure of the pressure pump discharging the cleaning agent. When 70% < V ≤ 90%, it indicates that the sewage flow rate is relatively large and impurities in the water are not easily adhered to the transfer pump. At this time, the driving module controls the pressure pump to discharge a small amount of cleaning agent, and at the same time, the driving pressure of the pressure pump discharging the cleaning agent is relatively small. When 50% < V ≤ 70%, it indicates that the sewage flow rate is relatively large and impurities in the water normally stay in the transfer pump. At this time, the driving module controls the pressure pump to discharge a normal amount of cleaning agent, and at the same time, the driving pressure of the pressure pump discharging the cleaning agent is relatively normal. When 30% < V ≤ 50%, it indicates that the sewage flow rate is relatively small and impurities in the water are more likely to adhere to the transfer pump. At this time, the driving module controls the pressure pump to discharge a large amount of cleaning agent, and at the same time, the driving pressure of the pressure pump discharging the cleaning agent is relatively large.

[0025] According to the above technical solution, in S8, when 30% ≥ V, the driving module drives the motor to operate, changes the operating power of the motor according to the speed of the flow rate, changes the rotation speed of the rotating cavity, and at the same time, drives the motor to operate alternately, enabling the rotating cavity to rotate alternately, and changes the alternating rotation frequency according to the speed of the flow rate. When 30% ≥ V > 20%, it indicates that the speed of the flow rate is too small. At this time, the driving module controls the operating power of the motor to be relatively small, and at the same time, the alternating operation frequency of the driving motor is relatively small, so that the force of the rotating cavity stirring the water back and forth is relatively small. When 20% ≥ V > 10%, it indicates that the speed of the flow rate is extremely small. At this time, the driving module controls the operating power of the motor to be relatively large, and at the same time, the alternating operation frequency of the driving motor is relatively large, so that the force of the rotating cavity stirring the water back and forth is relatively large.

[0026] According to the above technical solution, in S9, when R > 100%, the drive module controls the indicator light to change from green to red, which is used to remind the operator that there are too many particulate matters in the sewage, and continuous discharge is likely to damage the delivery pump, thus giving an alarm. At the same time, the drive intelligent regulation system stops running and performs an emergency stop to prevent the stones in the sewage from getting stuck in the delivery pump and causing damage to the delivery pump, and to prevent subsequent inability to continue discharging sewage, which plays a protective role for the device.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, by setting up an intelligent regulation system and a cleaning device, the delivery pump is intelligently cleaned through the intelligent regulation system and the cleaning device, and the cleaning pressure can be automatically adjusted during cleaning, and the cleaning effect is better.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-5, the present invention provides a technical solution: a self-regulating control system for the cleaning pressure of a transfer pump, including a cleaning device and an intelligent regulation system. The cleaning device includes a chassis 1, above which a cleaning pump 2 is fixedly installed. The cleaning pump 2 is connected to an external clean water pipeline. A pipeline on the left side of the cleaning pump 2 is connected to a transfer pump 3, and the transfer pump 3 is connected to an external sewage pipeline. Inside the transfer pump 3, a water quality detector 4 is fixedly installed. A pipeline above the cleaning pump 2 is connected to a pressure pump 5, and the right side of the pressure pump 5 is connected to an external cleaning agent pipeline. Above the right side of the chassis 1, a bracket 6 is fixedly installed. On the upper left side of the bracket 6, a controller 7 is fixedly installed. On the surface of the controller 7, an indicator light 8 is fixedly installed. The intelligent regulation system is electrically connected to the controller 7, the indicator light 8, the cleaning pump 2, the transfer pump 3, the water quality detector 4, the cleaning pump 2, and the pressure pump 5 respectively. When the operator turns on the controller 7, the controller 7 electrically drives to drive the intelligent regulation system to operate. The intelligent regulation system drives the transfer pump 3 to operate through electrical drive. The transfer pump 3 conducts the transportation work on the sewage. At this time, the intelligent regulation system then controls the water quality detector 4 to detect the water quality through electrical drive, obtaining the turbidity of the water quality. The intelligent regulation system then drives the cleaning pump 2 to operate according to the turbidity of the water quality. The cleaning pump 2 extracts and pressurizes the external clean water and then injects it into the transfer pump 3. After the clean water is pressurized, it vigorously flushes the inside of the transfer pump 3. At the same time, it controls the operation of the pressure pump 5 through electrical drive. The pressure pump 5 extracts the cleaning agent from the outside and injects it into the cleaning pump 2 through the pipeline, and then discharges it into the transfer pump 3 after being mixed with the clean water. The pressure pump 5 can control the amount of the discharged cleaning agent and the pressure when discharging the cleaning agent, changing the impact force when the cleaning agent enters the cleaning pump 2, and changing the lighting condition of the indicator light 8 according to the turbidity of the water quality. When the turbidity does not exceed the standard, it shows a green light, and when the turbidity exceeds the standard, it shows a red light. Through the intelligent regulation system and the cleaning device, the transfer pump 3 is intelligently cleaned, and at the same time, the cleaning pressure can be automatically adjusted during cleaning, and the cleaning effect is better;

[0037] Inside the transfer pump 3, a rotating cavity 9 is fixedly installed. Above the rotating cavity 9, a motor 10 is fixedly installed. On the rear side of the right side of the transfer pump 3, a flowmeter 11 is connected to the pipeline. The flowmeter 11 is connected to the external sewage pipeline. The intelligent regulation system is electrically connected to the motor 10 and the flowmeter 11 respectively. Through the above steps, the intelligent regulation system operates, controls the operation of the flowmeter 11 through electrical drive. The flowmeter 11 determines the flow rate of the sewage when it enters the transfer pump 3, obtaining the speed of the sewage flow. When the speed of the sewage flow is less than a certain degree, the intelligent regulation system controls the transfer pump 3 to be closed through electrical drive, and at the same time controls the operation of the motor 10 through electrical drive. The motor 10 drives the rotating cavity 9 to rotate. The rotating cavity 9 stirs the cleaning agent and the clean water entering the transfer pump 3 back and forth, accelerating the cleaning speed inside the transfer pump 3 and improving the cleaning quality;

[0038] The intelligent adjustment system includes a detection module, a processing module, a data transmission module, a data receiving module, a calculation module and a control module. The detection module is electrically connected to the water quality detector 4, the flow velocity meter 11 and the data transmission module respectively. The data receiving module is electrically connected to the calculation module and the data transmission module respectively. The calculation module is electrically connected to the control module. The control module is electrically connected to the cleaning pump 2 and the delivery pump 3;

[0039] The detection module is used to detect the water quality of the sewage through the water quality detector 4, convert the detected water quality data into the turbidity of the water quality, and collect the data. The detection module is used to measure the flow velocity of the sewage entering the delivery pump 3 through the flow velocity meter 11, convert the detected flow velocity data into the speed of the flow velocity, and collect the data. The processing module is used to assist in controlling the device according to the data detected. The data transmission module is used to transmit the detected data. The data receiving module is used to receive the transmitted data. The calculation module is used to automatically calculate the result through the received data. The control module is used to control the cleaning pump 2 and the delivery pump 3 respectively according to the calculated result;

[0040] The processing module includes a data collection module, a conversion module and a driving module. The data collection module is electrically connected to the detection module. The data collection module is electrically connected to the conversion module. The conversion module is electrically connected to the driving module. The driving module is electrically connected to the cleaning pump 2, the delivery pump 3, the pressure pump 5, the motor 10 and the indicator light 8;

[0041] The data collection module is used to collect the turbidity of the water quality and the speed of the sewage flow detected by the detection module. The conversion module is used to convert the collected data to obtain the driving data for the subsequent structure. The driving module is used to control the operating modes of the cleaning pump 2, the delivery pump 3, the pressure pump 5, the motor 10 and the indicator light 8 according to the converted result;

[0042] The intelligent adjustment system includes the following operating steps:

[0043] S1. The operator turns on the controller 7. The controller 7 electrically drives to drive the intelligent adjustment system to operate. The intelligent adjustment system electrically drives to drive the delivery pump 3 to operate. The delivery pump 3 conducts the conveying work on the sewage;

[0044] S2. The intelligent adjustment system electrically drives to control the water quality detector 4 to operate. The water quality detector 4 detects the water quality of the sewage, converts the detected water quality data into the turbidity of the water quality, measures the flow velocity of the sewage through the flow velocity meter 11, and obtains the speed of the sewage flow. The sewage flow affects the size of the turbidity during water quality detection. wherein, R 检 is the turbidity of the water quality of the sewage detected by the water quality detector 4, R 设is the turbidity of the sewage set within the thermometer 10, R is the real-time turbidity of the sewage, R 系 is the change amount of the water quality turbidity under the sewage flow rate of a single unit, V is the real-time flow rate of the sewage. At the same time, the flowmeter 11 measures the flow rate of the sewage when it enters the transfer pump 3, wherein, V 检 is the sewage flow rate detected by the flowmeter 11, V 设 is the set flow rate within the flowmeter 11. When the real-time flow rate of the sewage is greater than 100%, it means the sewage is discharged smoothly and no cleaning is required. When the real-time flow rate of the sewage is less than 100%, it means the sludge in the sewage accumulates in the transfer pump 3 and cleaning is needed. The two obtained data are transmitted to the data transmission module and the data collection module;

[0045] S3. The data transmission module then transmits the data out. The transmitted data is received by the data receiving module. The received data is transmitted from the data receiving module to the calculation module through electrical transmission. The calculation module automatically calculates the obtained data to get the result and inputs the result into the control module;

[0046] S4. The control module drives the cleaning pump 2 to operate according to the water quality turbidity, controls the water pressure when the cleaning pump 2 injects clean water into the transfer pump 3, thereby changing the cleaning intensity. At the same time, it changes the operation mode of the cleaning pump 2 to make the cleaning pump 2 operate intermittently, changes the intermittent operation time of the cleaning pump 2 according to the water quality turbidity, and controls the mutual operating power of the transfer pump 3 and the cleaning pump 2 according to the sewage flow velocity. After the water quality turbidity is greater than the system set value, it enters S9, otherwise it enters S5;

[0047] S5. At the same time, the data collection module collects the data and transmits the data into the conversion module. The conversion module converts the data to get the result and inputs the result into the driving module;

[0048] S6. The driving module changes the operation mode of the cleaning pump 2 again according to the sewage flow rate. The flow rate affects the residence time of impurities in the water in the transfer pump 3. According to the flow rate and the water quality turbidity, it changes the water pressure of the cleaning pump 2 and the intermittent time of the intermittent operation;

[0049] S7. The driving module drives the pressure pump 5 to operate, changes the cleaning agent dosage discharged by the pressure pump 5 into the cleaning pump 2 according to the sewage flow rate. At the same time, the greater the water pressure of the clean water injected by the cleaning pump 2 into the transfer pump 3, the greater the pressure for the pressure pump 5 to discharge the cleaning agent, so that the clean water and the cleaning agent can be integrated with each other. When the flow rate is less than the system set value, it enters S8, otherwise it enters S10;

[0050] S8. The drive module drives the motor 10 to operate and changes the operating power of the motor 10 according to the flow rate. The motor 10 drives the rotating cavity 9 to rotate, thereby changing the rotation speed of the rotating cavity 9. At the same time, the drive motor 10 operates alternately, causing the rotating cavity 9 to rotate alternately, and changing the alternating rotation frequency according to the flow rate. Then it proceeds to S10;

[0051] S9. At this time, the drive module controls the drive of the indicator light 8 to change the lighting mode through electric drive. The indicator light 8 changes from green to red. At the same time, the drive intelligent regulation system stops operating and performs an emergency stop;

[0052] S10. After the sewage transportation is completed, the controller 7 is turned off and the intelligent regulation system stops operating. If the sewage transportation work continues, it returns to S1;

[0053] In S1 to S4, the water quality detector 4 analyzes and calculates the turbidity of the sewage quality. Then, according to the analyzed sewage quality turbidity, the cleaning pump 2 is driven to operate, and the mutual operating powers of the transfer pump 3 and the cleaning pump 2 are controlled according to the sewage flow rate. Among them, P 清 is the operating power of the cleaning pump 2, and P 输Let \(P\) be the operating power of the transfer pump 3. The more turbid the water quality is, the greater the operating power of the cleaning pump 2. At the same time, the slower the flow rate of the sewage due to higher viscosity, which further increases the flushing force of the cleaning pump 2. When \(70\% \lt R\leq90\%\), it indicates a relatively high turbidity of the water quality. At this time, the control module drives the cleaning pump 2 to inject clear water with a relatively high pressure, and the intermittent operation interruption time of the cleaning pump 2 is shorter, performing high-frequency flushing work. When \(50\% \lt R\leq70\%\), it indicates that the water quality turbidity is relatively normal. At this time, the control module drives the cleaning pump 2 to inject clear water with a normal pressure, and the intermittent operation interruption time of the cleaning pump 2 is normal, performing normal-frequency flushing work. When \(30\% \lt R\leq50\%\), it indicates a relatively low turbidity of the water quality. At this time, the control module drives the cleaning pump 2 to inject clear water with a relatively low pressure, and the intermittent operation interruption time of the cleaning pump 2 is longer, performing low-frequency flushing work. For relatively high water quality turbidity, increase the pressure when the cleaning pump 2 injects clear water, increase the flushing force inside the transfer pump 3, so that impurities in the water can be quickly removed, avoiding blockage of the drainage port of the transfer pump 3 by excessive impurities and affecting the use of the device. At the same time, make the cleaning pump 2 operate intermittently, reduce the discharge of clear water, save water resources, and make the intermittent operation time shorter, increase the flushing frequency, and improve the effect of removing impurities. At the same time, for relatively low water quality turbidity, reduce the pressure when the cleaning pump 2 injects clear water, reduce the flushing force inside the transfer pump 3. The greater the pressure, the more clear water is discharged. Therefore, for less impurities, reduce the water volume discharge, increase the intermittent operation time, and perform low-frequency flushing to further reduce the water volume discharge. At the same time, it has a cleaning effect, performs intelligent processing of impurities, and enables the clear water in the cleaning pump 2 to smoothly enter the transfer pump 3, thus completing the cleaning work;

[0054] In S2 and S6, T 泵 =R 2 *T 系 , where, R 变 is the change magnitude of the water quality turbidity, T 系 is the interruption time magnitude of the cleaning pump 2 operation under the water quality turbidity of a single unit, T 泵For the intermittent running time of the cleaning pump 2, the driving module controls the cleaning pump 2 to operate at high power, so that the clear water can be flushed with greater force. At the same time, the intermittent time of the cleaning pump 2 for flushing changes to a large extent. When 70% < V ≤ 90%, it means that the sewage flow rate is relatively large and the sewage is relatively dilute and thick, and impurities in the water are not easily adhered to the conveying pump 3. At this time, the driving module controls the cleaning pump 2 to greatly increase the intermittent running time on the original basis. When 50% < V ≤ 70%, it means that the sewage flow rate is normal. At this time, the driving module controls the cleaning pump 2 to increase the intermittent running time on the original basis by a normal margin. When 30% < V ≤ 50%, it means that the sewage flow rate is relatively small and the sewage is relatively viscous, and impurities in the water are more likely to adhere to the conveying pump 3. At this time, the driving module controls the cleaning pump 2 to slightly increase the intermittent running time on the original basis. For relatively large sewage flow rate, the sewage is relatively turbulent, and the water flow can quickly discharge impurities, and the residence time of impurities in the conveying pump 3 is short. At this time, the cleaning pump 2 is made to operate at high power to increase the flushing force on the impurities. At the same time, the cleaning pump 2 is made to greatly increase the intermittent time on the original basis, and the time when the cleaning pump 2 stops flushing is increased, which not only ensures the continuous operation of the impurity flushing work, but also reduces the water output and water waste. At the same time, for relatively small sewage flow rate, the sewage flow is slow, and the residence time of impurities in the conveying pump 3 is long, and it is easy to accumulate in the conveying pump 3. At this time, the cleaning pump 2 is made to slightly increase the intermittent time on the original basis, so that the intermittent time is not too long, and the cleaning effect on the impurities is increased, preventing the influence on the use effect of the conveying pump 3 caused by the long-term accumulation of impurities adhering to the inner wall of the conveying pump 3;

[0055] In S7, the drive module drives the pressure pump 5 to operate, changing the amount of cleaning agent discharged by the pressure pump 5 into the cleaning pump 2 according to the sewage flow rate. At the same time, the water pressure of the clean water injected by the cleaning pump 2 into the transfer pump 3 affects the pressure of the cleaning agent discharged by the pressure pump 5. When 70% < V ≤ 90%, it indicates that the sewage flow rate is relatively large and impurities in the water are not easily adhered to the transfer pump 3. At this time, the drive module controls the pressure pump 5 to discharge a small amount of cleaning agent, and at the same time, the pressure of the cleaning agent discharged by the pressure pump 5 is relatively small. When 50% < V ≤ 70%, it indicates that the sewage flow rate is relatively large and impurities in the water normally stay in the transfer pump 3. At this time, the drive module controls the pressure pump 5 to discharge a normal amount of cleaning agent, and at the same time, the pressure of the cleaning agent discharged by the pressure pump 5 is normal. When 30% < V ≤ 50%, it indicates that the sewage flow rate is relatively small and impurities in the water are more easily adhered to the transfer pump 3. At this time, the drive module controls the pressure pump 5 to discharge a large amount of cleaning agent, and at the same time, the pressure of the cleaning agent discharged by the pressure pump 5 is relatively large. For a relatively large sewage flow rate where impurities in the water are not easily adhered to the transfer pump 3, the discharge of the cleaning agent is reduced. At this time, the flushing force of the cleaning pump 2 is also small, and the cleaning agent can smoothly blend into the clean water, thereby reducing the discharge pressure of the cleaning agent and reducing the waste of the cleaning agent. Further reducing the pressure when discharging the cleaning agent can further reduce the discharge amount of the cleaning agent, saving the cleaning agent fully. At the same time, for a relatively small sewage flow rate where impurities in the water are more easily adhered to the transfer pump 3, the discharge of the cleaning agent is increased. At this time, the flushing force of the cleaning pump 2 is also large, and the cleaning agent cannot quickly and smoothly blend into the clean water. Therefore, by increasing the discharge pressure of the cleaning agent, the cleaning agent can be promptly flushed into the clean water to improve the cleaning effect. Further increasing the pressure when discharging the cleaning agent can further increase the discharge amount of the cleaning agent, making the effect of the cleaning agent in cleaning the internal impurities of the transfer pump 3 better;

[0056] In S8, when 30% ≥ V, the drive module drives the motor 10 to operate, and changes the operating power of the motor 10 according to the flow rate, changes the rotation speed of the rotating cavity 9, and at the same time drives the motor 10 to operate alternately, so that the rotating cavity 9 rotates alternately, and changes the alternating rotation frequency according to the flow rate. When 30% ≥ V > 20%, it means that the flow rate is too slow. At this time, the drive module controls the operating power of the motor 10 to be small, and at the same time the alternating operating frequency of the motor 10 is small, so that the force of the rotating cavity 9 stirring the water back and forth is small. When 20% ≥ V > 10%, it means that the flow rate is extremely slow. At this time, the drive module controls the operating power of the motor 10 to be large, and at the same time the alternating operating frequency of the motor 10 is large, so that the force of the rotating cavity 9 stirring the water back and forth is large. For the sewage with too slow flow rate, the motor 10 rotates at a low power, and at the same time the alternating rotation frequency of the motor 10 is small, so that the rotating cavity 9 rotates alternately with low efficiency, thereby stirring the inside of the delivery pump 3 slightly, increasing the cleaning effect on impurities, preventing the impurities from adhering to the inner wall of the delivery pump 3, improving the sewage discharge efficiency. At the same time, for the sewage with extremely slow flow rate, the motor 10 rotates at a high power, and at the same time the alternating rotation frequency of the motor 10 is large, so that the rotating cavity 9 rotates alternately at a high frequency, thereby stirring the inside of the delivery pump 3 greatly, increasing the force of peeling off the impurities on the inner wall of the delivery pump 3, strengthening the cleaning effect, and at the same time making the cleaning agent entering the delivery pump 3 fully exert its cleaning effect;

[0057] In S9, when R > 100%, the drive module controls the indicator light 8 to change from green to red, which is used to remind the operator that there are too many particulate matters in this sewage, and continuous discharge is likely to damage the delivery pump 3, thus sending an alarm. At the same time, the intelligent adjustment system is driven to stop running and perform an emergency stop operation to prevent the stones in the sewage from getting stuck in the delivery pump 3 and causing damage to the delivery pump 3, and to prevent the subsequent inability to continue discharging sewage, which plays a protective role for the device.
