Description

Technical Field

[0001] The invention relates to the technical field of pressure self-regulation, in particular to a cleaning pressure self-regulation control system of a delivery pump. Background Art

[0002] A delivery pump is needed in the process of discharging sewage in the pool. The delivery pump can speed up the sewage discharge speed and improve the sewage discharge efficiency. When the sewage is discharged, the large number of impurities in the water can easily block the delivery pump, causing damage to the delivery pump. Therefore, the delivery pump needs to be cleaned in real time when the sewage is discharged to avoid blockage. There is no need to clean it when the sewage is discharged smoothly. However, when the sewage is about to be discharged, the sludge at the bottom of the pool is sucked into the delivery pump, and the flow rate of sewage in the delivery pump is significantly slowed down.

[0003] The existing cleaning device cannot intelligently adjust the pressure when cleaning the inside of the delivery pump, which affects the cleaning effect. In addition, the pressure cannot be adjusted according to the turbidity of the water during the cleaning process, which affects 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 object of the present invention is to provide a self-regulating control system for cleaning pressure of a delivery pump to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a self-regulating control system for cleaning pressure of a delivery pump, comprising a cleaning device and an intelligent regulating system, characterized in that: the cleaning device comprises a chassis, a cleaning pump is fixedly installed above the chassis, the cleaning pump is connected to an external clean water pipe, the left pipe of the cleaning pump is connected to a delivery pump, the delivery pump is connected to an external sewage pipe, a water quality detector is fixedly installed inside the delivery pump, a pressure pump is connected to the pipe above the cleaning pump, the right side of the pressure pump is connected to an external cleaning agent pipe, 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 regulating 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 chamber is fixedly installed in the middle of the delivery pump, a motor is fixedly installed above the rotating chamber, a flow meter is connected to the right rear pipe of the delivery pump, the flow meter is connected to the external sewage pipe, and the intelligent adjustment system is electrically connected to the motor and the flow meter 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 the water quality detector, the 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, and the control module is electrically connected to the cleaning pump and the delivery pump.

[0008] The detection module is used to detect the water quality of sewage through a water quality detector, convert the detected water quality data into water turbidity, and collect the data. The detection module is used to measure the flow rate of sewage entering the delivery pump through a flow meter, convert the detected flow rate data into the speed of flow, and collect the data. The processing module is used to assist in controlling the device according to the data obtained by the detection. The data transmission module is used to transmit the detected data, and 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, and 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, and the driving module is electrically connected to the cleaning pump, the delivery pump, the pressure pump, the motor, and the indicator light;

[0010] The data collection module is used to collect the data based on the water turbidity and sewage flow rate detected by the detection module. The conversion module is used to convert the collected data to obtain subsequent driving data for the structure. The driving module is used to control the operating mode of the cleaning pump, delivery pump, pressure pump, motor, and indicator light according to the conversion 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 electrically drives the intelligent regulation system to operate. The intelligent regulation system electrically drives the delivery pump to operate, and the delivery pump delivers sewage.

[0013] S2. The intelligent regulation system controls the operation of the water quality detector through electric drive. The water quality detector detects the water quality of the sewage, converts the detected water quality data into the degree of water turbidity, and measures the flow rate of the sewage through the flow meter to obtain the speed of the sewage flow rate. The sewage flow rate affects the degree of turbidity during water quality detection. Among them, R 检is the turbidity of sewage water detected by the water quality detector, R 设 is the sewage turbidity set in the temperature meter, R is the real-time turbidity of the sewage, and R 系 is the change in water turbidity at a single unit sewage flow rate, V is the real-time flow rate of the sewage, and the flow rate of the sewage entering the delivery pump is measured by the flow meter. Among them, V 检 is the sewage flow rate detected by the flow meter, V 设 is the flow rate set 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 is accumulated in the delivery pump and needs to be cleaned. The two types of data obtained are transmitted to the data transmission module and the data collection module;

[0014] S3, the data transmission module transmits the data, 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 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 turbidity of the water quality, controls the water pressure when the clean water of the cleaning pump is injected into the delivery pump, thereby changing the cleaning intensity, and at the same time changes the operation mode of the cleaning pump to make the cleaning pump intermittently operate, changes the intermittent operation time of the cleaning pump according to the turbidity of the water quality, and controls the mutual operation power of the delivery pump and the cleaning pump according to the flow speed of the sewage. When the turbidity of the water quality is greater than the system setting value, enter S9, otherwise enter S5;

[0016] S5, at the same time, the data collection module collects the data and transmits the data to the conversion module, the conversion module converts the data to obtain the result, and inputs the result to the driving module;

[0017] S6. The driving module changes the operation mode of the cleaning pump again according to the speed of the sewage flow, which affects the residence time of impurities in the water in the delivery pump. The driving module changes the water pressure of the cleaning pump and the intermittent operation time according to the speed of the water flow and the turbidity of the water.

[0018] S7, the driving module drives the pressure pump to operate, and changes the amount of cleaning agent discharged into the cleaning pump by the pressure pump according to the speed of the sewage flow. At the same time, the greater the pressure of the clean water injected into the delivery pump by the cleaning pump, the greater the pressure of the cleaning agent discharged by the pressure pump, so that the clean water and the cleaning agent can be integrated with each other. When the flow speed is less than the system setting value, enter S8, otherwise enter 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 indicator light to change its lighting mode 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, and then drives the cleaning pump to operate according to the turbidity of the water quality obtained after analysis, and controls the mutual operating power of the conveying pump and the cleaning pump according to the sewage flow rate. Among them, P 清 is the operating power of the cleaning pump, P 输 is the operating power of the conveying pump. The more turbid the water quality is, the greater the operating power of the cleaning pump. At the same time, the slower the sewage viscosity and flow rate are, 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 at the same time, the intermittent time of driving the cleaning pump to operate intermittently is shorter, and high-frequency flushing work is carried out. 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 at the same time, the intermittent time of driving the cleaning pump to operate intermittently is relatively normal, and normal-frequency flushing work is carried out. 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 at the same time, the intermittent time of driving the cleaning pump to operate intermittently is longer, and low-frequency flushing work is carried out.

[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, T 泵For the intermittent running time of the cleaning pump, the driving module controls the cleaning pump to operate at high power, enabling the clear water to conduct a stronger flushing. Meanwhile, the intermittent time of the cleaning pump for flushing varies significantly. 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 conveying pump. At this time, the driving module controls the cleaning pump to significantly increase the original intermittent running 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 running 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 conveying pump. At this time, the driving module controls the cleaning pump to slightly increase the original intermittent running 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 clear water injected by the cleaning pump into the conveying 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 conveying 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 pressure of the driving 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 conveying 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 pressure of the driving pressure pump discharging the cleaning agent is 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 conveying 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 pressure of the driving 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 motor to have a relatively small operating power, and at the same time, the alternating operation frequency of the driving motor is relatively small, making the force of the rotating cavity stirring the water back and forth 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 motor to have a relatively large operating power, and at the same time, the alternating operation frequency of the driving motor is relatively large, making the force of the rotating cavity stirring the water back and forth relatively large.

[0026] According to the above technical solution, in S9, when R>100%, the driving module controls the indicator light to change from green to red, which is used to remind the operator that there are too many particles in the sewage, and continued discharge may easily damage the delivery pump, thereby issuing an alarm and driving the intelligent adjustment system to stop running and perform an emergency stop to prevent stones in the sewage from getting stuck in the delivery pump and causing damage to the delivery pump, thereby preventing the subsequent inability to discharge sewage, thereby protecting the device.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention, by setting up an intelligent adjustment system and a cleaning device, can intelligently clean the delivery pump, and can automatically adjust the cleaning pressure during cleaning, so the cleaning effect is better.

At this time, the intelligent regulating system controls the water quality detector 4 through the electric drive to detect the water quality, and obtains the turbidity of the water quality. The intelligent regulating system drives the cleaning pump 2 to operate according to the turbidity of the water quality. The cleaning pump 2 extracts the external clean water and then injects it into the delivery pump 3 after pressurization. After the clean water is pressurized, the inside of the delivery pump 3 is vigorously flushed. At the same time, the pressure pump 5 is controlled by the electric drive to operate. The pressure pump 5 extracts the cleaning agent from the outside and injects it into the cleaning pump 2 through the pipeline. After merging with the clean water, it is discharged into the delivery pump 3.

Through the above steps, the intelligent adjustment system operates, and the flow meter 11 is controlled by electric drive to operate. The flow meter 11 determines the flow rate of sewage when it enters the delivery pump 3, and obtains the flow rate of the sewage. When the flow rate of the sewage is less than a certain degree, the intelligent adjustment system controls the delivery pump 3 to be closed through electric drive, and controls the motor 10 to operate through electric drive. The motor 10 drives the rotating chamber 9 to rotate, and the rotating chamber 9 stirs the cleaning agent and clean water entering the delivery pump 3 back and forth, thereby accelerating the cleaning speed inside the delivery pump 3 and improving the cleaning quality.

[0038] The intelligent regulation 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 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 water turbidity degree, and collect the data.

[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, and 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 data according to 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 subsequent driving data of the structure. The driving module is used to control the operation mode of the cleaning pump 2, the delivery pump 3, the pressure pump 5, the motor 10, and the indicator light 8 according to the conversion result;

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

[0043] S1. The operator turns on the controller 7, and the controller 7 electrically drives the intelligent regulating system to operate. The intelligent regulating system electrically drives the delivery pump 3 to operate, and the delivery pump 3 transports the sewage;

[0044] S2. The intelligent regulation system controls the operation of the water quality detector 4 through electric drive. 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, and measures the flow rate of the sewage through the flow meter 11 to obtain the speed of the sewage flow rate. The sewage flow rate affects the turbidity degree during water quality detection. Among them, R 检 is the turbidity of sewage water detected by water quality detector 4, R 设is the sewage turbidity set in the temperature meter 10, R is the real-time turbidity of the sewage, and R 系 is the change in water turbidity at a single unit sewage flow rate, V is the real-time flow rate of the sewage, and the flow rate of the sewage entering the delivery pump 3 is measured by the flow meter 11. Among them, V 检 is the sewage flow rate detected by the flow meter 11, V 设 is the flow rate set in the flow meter 11. 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 is accumulated in the delivery pump 3 and needs to be cleaned. The two types of data obtained are transmitted to the data transmission module and the data collection module;

[0045] S3, the data transmission module transmits the data, 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 obtain 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 turbidity of the water quality, controls the water pressure when the clean water of the cleaning pump 2 is injected into the delivery pump 3, thereby changing the cleaning intensity, and at the same time changing the operation mode of the cleaning pump 2, so that the cleaning pump 2 is intermittently operated, and changes the intermittent operation time of the cleaning pump 2 according to the turbidity of the water quality, and controls the mutual operation power of the delivery pump 3 and the cleaning pump 2 according to the flow speed of the sewage, and enters S9 when the turbidity of the water quality is greater than the system setting value, otherwise enters S5;

[0047] S5, at the same time, the data collection module collects the data and transmits the data to the conversion module, the conversion module converts the data to obtain the result, and inputs the result to the driving module;

[0048] S6, the driving module changes the operation mode of the cleaning pump 2 again according to the speed of the sewage flow, which affects the residence time of impurities in the water in the delivery pump 3, and changes the water pressure of the cleaning pump 2 and the intermittent operation time according to the speed of the water flow and the turbidity of the water quality;

[0049] S7, the driving module drives the pressure pump 5 to operate, and changes the amount of cleaning agent discharged by the pressure pump 5 into the cleaning pump 2 according to the speed of the sewage flow. At the same time, the greater the pressure of the clean water injected into the delivery pump 3 by the cleaning pump 2, the greater the pressure of the cleaning agent discharged by the pressure pump 5, so that the clean water and the cleaning agent can be integrated with each other. When the flow speed is less than the system setting value, enter S8, otherwise enter S10;

[0050] S8, the driving 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 chamber 9 to rotate, thereby changing the rotation speed of the rotating chamber 9, and at the same time drives the motor 10 to operate alternately, so that the rotating chamber 9 rotates alternately, and changes the alternating rotation frequency according to the flow rate, and then enters S10;

[0051] S9, at this time, the driving module changes the lighting mode of the indicator light 8 through the electric drive control, and the indicator light 8 changes from green to red, and at the same time drives the intelligent adjustment system to stop running and perform emergency stop work;

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

[0053] In S1 to S4, the turbidity of the sewage water is analyzed and calculated by the water quality detector 4, and the cleaning pump 2 is driven to operate according to the turbidity of the water obtained after the analysis, and the mutual operating power of the delivery pump 3 and the cleaning pump 2 is controlled according to the flow speed of the sewage. Among them, P 清 is the operating power of the cleaning pump 2, P 输is 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 its higher viscosity, which further increases the flushing force of the cleaning pump 2. When 70% < R ≤ 90%, it indicates a relatively high degree of water quality turbidity. At this time, the control module drives the cleaning pump 2 to inject clean water with a relatively high pressure, and at the same time, the intermittent operation time of the cleaning pump 2 is shorter, performing 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 2 to inject clean water with a normal pressure, and at the same time, the intermittent operation time of the cleaning pump 2 is normal, performing normal-frequency flushing work. When 30% < R ≤ 50%, it indicates a relatively low degree of water quality turbidity. At this time, the control module drives the cleaning pump 2 to inject clean water with a relatively low pressure, and at the same time, the intermittent operation time of the cleaning pump 2 is longer, performing low-frequency flushing work. For a relatively high degree of water quality turbidity, increase the pressure when the cleaning pump 2 injects clean water, increase the flushing force inside the transfer pump 3, so that the 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 clean 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 a relatively low degree of water quality turbidity, reduce the pressure when the cleaning pump 2 injects clean water, reduce the flushing force inside the transfer pump 3. The greater the pressure, the more clean water is discharged. Therefore, for less impurities, reduce the water discharge, and increase the intermittent operation time to perform low-frequency flushing, further reducing the water discharge. At the same time, it has a cleaning effect, performs intelligent processing of impurities, and can make the clean water in the cleaning pump 2 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 intermittent operation time magnitude of the cleaning pump 2 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 clean 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 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 original intermittent running time. 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 original intermittent running time by a normal amplitude. 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 increase the original intermittent running time by a small amplitude. For the case where the sewage flow rate is large, the sewage is relatively turbulent, and the water flow can quickly discharge the impurities, and the residence time of the 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 original intermittent time, and the time when the cleaning pump 2 stops flushing is increased, which can not only ensure the continuous operation of the impurity flushing work, but also reduce the water output and water waste. At the same time, for the case where the sewage flow rate is small, the sewage flows slowly, and the residence time of the impurities in the conveying pump 3 is long, and the impurities are likely to accumulate in the conveying pump 3. At this time, the cleaning pump 2 is made to increase the original intermittent time by a small amplitude, so that the intermittent time will not be too long, and the cleaning effect on the impurities is increased, preventing the impurities from accumulating for too long and adhering to the inner wall of the conveying pump 3 and affecting the use effect of the conveying pump 3;

[0055] In S7, the driving module drives the pressure pump 5 to operate, changes the amount of cleaning agent discharged by the pressure pump 5 into the cleaning pump 2 according to the speed of the sewage flow, and 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 pressure pump 5 to discharge 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 inside of the transfer pump 3. At this time, the driving module controls the pressure pump 5 to discharge a small amount of cleaning agent, and at the same time, the pressure of the pressure pump 5 to discharge 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 3. At this time, the driving module controls the pressure pump 5 to discharge a normal amount of cleaning agent, and at the same time, the pressure of the pressure pump 5 to discharge the cleaning agent is normal. When 30% < V ≤ 50%, it indicates that the sewage flow rate is relatively small and impurities in the water are relatively easy to adhere to the inside of the transfer pump 3. At this time, the driving module controls the pressure pump 5 to discharge a large amount of cleaning agent, and at the same time, the pressure of the pressure pump 5 to discharge the cleaning agent is relatively large. For a relatively large sewage flow rate where impurities in the water are not easily adhered to the inside of the transfer pump 3, the discharge of the cleaning agent is reduced. At this time, the flushing intensity 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, fully saving the cleaning agent. At the same time, for a relatively small sewage flow rate where impurities in the water are relatively easy to adhere to the inside of the transfer pump 3, the discharge of the cleaning agent is increased. At this time, the flushing intensity 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 impacted 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 impurities inside the transfer pump 3 better;

[0056] In S8, when 30% ≥ V, the driving module drives the motor 10 to run, and changes the running power of the motor 10 according to the speed of the flow, changes the rotation speed of the rotating chamber 9, and drives the motor 10 to run alternately, so that the rotating chamber 9 rotates alternately, and changes the alternating rotation frequency according to the speed of the flow. When 30% ≥ V> 20%, it means that the speed of the flow is too slow. At this time, the driving module controls the running power of the motor 10 to be relatively small, and at the same time, the driving motor 10 alternately runs at a relatively small frequency, so that the rotating chamber 9 stirs the water flow back and forth with relatively small force. When 20% ≥ V> 10%, it means that the speed of the flow is extremely slow. At this time, the driving module controls the running power of the motor 10 to be relatively large, and at the same time, the driving motor 10 alternately runs at a relatively large frequency, so that the rotating chamber 9 stirs the water flow back and forth with relatively small force. The force of the back-stirring water flow is relatively large. If the flow rate of the sewage is too slow, the motor 10 is rotated at a low power. At the same time, the driving motor 10 is rotated alternately at a low frequency, so that the rotating chamber 9 rotates alternately at a low efficiency, thereby stirring the inside of the delivery pump 3 slightly, increasing the cleaning effect of impurities, so that impurities cannot be adhered to the inner wall of the delivery pump 3, and improving the sewage discharge efficiency. At the same time, if the flow rate of the sewage is extremely slow, the motor 10 is rotated at a high power. At the same time, the driving motor 10 is rotated alternately at a high frequency, so that the rotating chamber 9 rotates alternately at a high frequency, thereby stirring the inside of the delivery pump 3 significantly, increasing the impurity stripping force on the inner wall of the delivery pump 3, and strengthening the cleaning effect. At the same time, the cleaning agent entering the delivery pump 3 can fully exert its cleaning effect;

[0057] In S9, when R>100%, the driving module controls the indicator light 8 to change from green to red, which is used to remind the operator that there are too many particles in the sewage, and continued discharge may easily damage the delivery pump 3, thereby sounding an alarm and driving the intelligent adjustment system to stop running and perform an emergency stop to prevent stones in the sewage from getting stuck in the delivery pump 3 and causing damage to the delivery pump 3, thereby preventing the subsequent inability to discharge sewage and protecting the device.
