Description

Technical Field

[0001] This invention relates to the field of cutting sewage pump technology, and more specifically, to an anti-clogging cutting sewage pump. Background Technology

[0002] Sewage pumps are widely used in sewage transportation, industrial discharge, and urban drainage. Since the transported medium usually contains foreign objects such as fibers, plastic fragments, and impurity particles, long-term operation can easily cause problems such as pump inlet blockage, impeller entanglement, and flow rate reduction. At present, some sewage pumps use cutting mechanisms to cut off the debris entering the pump body to reduce the probability of blockage. However, existing anti-blockage structures usually rely on mechanical cutting methods and lack the ability to detect and intelligently judge the operating status of sewage pumps in real time.

[0003] Existing blockage detection methods typically use single pressure or current detection to determine equipment malfunctions. These methods are easily affected by changes in operating conditions, fluctuations in sewage flow, and equipment aging, resulting in insufficient accuracy in blockage detection. Furthermore, existing technologies usually address blockages after they occur, failing to predict blockage trends in advance based on changes in operating parameters. This leads to increased equipment downtime for maintenance and affects the continuous operation of the sewage system.

When the detected blockage risk reaches the first threshold, the cutting mechanism is activated to actively prevent blockage. When the detected blockage risk reaches the second threshold, the operating load is reduced or shutdown protection is executed.

[0086] The operation recording unit is used to record the changes in the operating status of the sewage pump;

[0087] The fault tracing unit is used to analyze the causes of blockages based on historical data.

[0088] During operation, the data acquisition module collects inlet pressure, outlet pressure, motor operating current, flow rate, pump vibration, and cutting mechanism operating parameters in real time, and sends the collected data to the status sensing module. The status sensing module first filters and detects anomalies in the collected data, marking abnormal data caused by sensor interference. Then, it extracts the pressure difference change rate, current change rate, flow rate decrease ratio, and vibration change characteristics. The blockage identification module fuses and analyzes multiple operating characteristics. When it detects a continuous increase in the inlet and outlet pressure difference, an increase in the motor operating current, a decrease in the flow rate, and an increase in the vibration amplitude, it determines that the sewage pump is at risk of blockage. The system determines the blockage level based on the degree of change. The trend prediction module establishes a trend model based on the operating data over a continuous period of time, analyzes the direction of change of parameters such as pressure, current, and flow, and outputs early warning information when the predicted blockage risk continues to increase. After receiving the blockage status information, the intelligent control module generates a control strategy based on the blockage level. When the blockage is slight, it controls the cutting mechanism to increase the operating frequency. When the blockage is severe, it executes load reduction or shutdown protection operations. The data management module stores the operating data, status judgment results, and control commands throughout the detection process, providing data basis for subsequent equipment maintenance and operation optimization.

[0089] This invention acquires real-time data on pressure, current, flow rate, vibration, and speed of the sewage pump during operation using multiple sensors, and uses data analysis algorithms to identify the operating status. When debris becomes entangled inside the sewage pump or the flow channel tends to become blocked, it usually leads to a decrease in flow rate, changes in the inlet and outlet pressure difference, an increase in motor load, and abnormal vibration. This invention avoids misjudgment caused by judging a single parameter by comprehensively analyzing the changes in the above parameters. The system first uses a status perception module to extract operating characteristics, then uses a blockage identification module to determine the current blockage status, and then uses a trend prediction module to analyze the blockage development trend. According to the risk level, the intelligent control module automatically adjusts the working status of the cutting mechanism to achieve blockage prevention. Through the above methods, the sewage pump is transformed from a traditional passive blockage removal method to an active detection, early warning, and intelligent control method, improving the operational stability and anti-blockage reliability of the sewage pump.

[0090] This invention achieves real-time perception and comprehensive analysis of the operating status of the anti-clogging cutting sewage pump by collecting multi-dimensional operating parameters such as pressure, current, flow rate, vibration, and rotational speed, thereby improving the accuracy and reliability of clogging detection. Through feature extraction and fusion of multi-source data, it can identify normal operation, minor clogging, continuous clogging, and severe clogging, enabling intelligent judgment of the degree of clogging. The trend prediction module analyzes the changing patterns of operating parameters, allowing for the early detection of abnormal trends and the output of risk warnings before clogging occurs, reducing the probability of sudden equipment shutdown. The intelligent control module automatically generates control strategies based on the clogging risk level, controlling the cutting mechanism and the sewage pump's operating status to achieve proactive clogging prevention and operational optimization, improving the equipment's automation level and continuous operation capability. Simultaneously, the data management module correlates and stores operating data, fault status, and control processes, enabling fault tracing, operation maintenance, and equipment status optimization, thus improving the operational safety, stability, and intelligence level of the anti-clogging cutting sewage pump.
