[0014] This invention provides another technical solution: an anti-clogging control system for an anti-clogging intelligent valve, the intelligent valve control system comprising:

[0015] The flow monitoring module is used to acquire the velocity and flow rate data of the fluid inside the smart valve. The acquired velocity and flow rate data are packaged with the basic data of the smart valve to generate a dataset. The dataset is then transmitted sequentially to the data processing module for processing based on a time series.

[0016] The data processing module is used to extract speed and flow data from the dataset, determine whether the speed and flow data are within a preset value range, and obtain control commands if they exceed or fall below the preset value, and transmit the control commands to the control module.

[0017] The control module is used to receive control commands, input the control commands into the command database for one-to-one matching, generate valve body control commands and anti-blocking control commands, drive the motor to receive the valve body control commands, and the anti-blocking mechanism to receive the anti-blocking control commands.

[0018] The feedback module is used to obtain instruction feedback from the drive motor and the anti-blocking mechanism, and at the same time obtain speed and flow data from the flow monitoring module. Based on the time series, it determines whether the speed and flow data are consistent, generates feedback data, and establishes a table.

[0019] Furthermore, the intelligent valve control system also includes:

[0020] The power supply module provides operating voltage to the flow monitoring module, data processing module, control module, and feedback module.

[0021] The wake-up calibration module is used to automatically synchronize the built-in real-time clock and the smart valve daily; at the same time, it acquires the time nodes when the control module issues valve control commands and anti-blocking control commands.

[0022] The remote data transmission module is used to obtain the dataset from the data processing module, transmit the dataset to the remote control terminal based on the Internet of Things, extract the basic data of the smart valves in the dataset, establish a smart valve network map, and display it on the remote control terminal.

[0024] Furthermore, the wake-up module is also used to obtain the time series of various data of the smart valve and compare them one by one with the real-time clock, and to continuously determine whether the drive motor and anti-blocking mechanism in the long-term shutdown state have reached the set wake-up time.

[0025] Furthermore, the early warning module includes:

[0026] The wake-up data of the wake-up module is obtained, the target data is extracted from the data, and the power threshold corresponding to the power module, the drive motor and the anti-blocking mechanism is established for the target data.

[0027] Extract the initial power of each drive motor and anti-blocking mechanism from the target data, and determine the actual power of each power module.

[0028] Analyze the power consumption characteristics of the drive motor and anti-blocking mechanism corresponding to the power module, and analyze the power consumption characteristics of the drive motor and anti-blocking mechanism based on the power consumption duration of the power consumption characteristics.

[0029] Determine whether the power consumption characteristics and power usage characteristics match preset characteristics. If they cannot match, an abnormal alarm is triggered.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. The valve controller receives a control signal and controls the output shaft at the lower end of the drive motor to rotate, which in turn drives the transmission disc to rotate synchronously. This causes the adjusting sleeve, which is fixed to the transmission disc, to rotate synchronously. The limiting block, which meshes with the adjusting sleeve, moves the piston rod up and down under the limiting action of the piston rod. This causes the lower piston to move the inner valve plate up and down, adjusting the space of the fluid in the valve core and thus adjusting the fluid flow rate. The adjustment is fully automatic and highly accurate. The guide sleeve effectively guides the movement of the inner valve plate, ensuring the verticality of the valve core movement, improving the sealing of the valve core piston groove, and extending the service life of the equipment.

[0032] 2. Based on the controlled flow rate, the inner valve plate moves upward, the tension shaft drives the crushing disc to move upward, and the sealing bushing extends and retracts while ensuring the sealing of the valve core piston groove. The anti-clogging motor rotates, driving the crushing disc to rotate, crushing impurities in the fluid within the valve core piston groove. The height of the inner valve plate is adjusted according to the flow rate to achieve the crushing effect based on the flow rate, thus achieving the anti-clogging function. This makes the operation more flexible and avoids the crushing disc running idle when there is a small flow and no blockage, extending the service life of the crushing disc and saving energy consumption.

[0033] 3. The drive motor and anti-blocking mechanism are periodically woken up by the wake-up module. If the drive motor and anti-blocking mechanism have not worked for a long time, periodic monitoring is performed. Based on the obtained power consumption characteristics, it is determined whether the drive motor and anti-blocking mechanism are normal, and abnormal equipment is detected in time. Alarms are issued for abnormal equipment, and maintenance prompts are sent through the remote terminal to facilitate timely maintenance and replacement by maintenance personnel. This ensures the working quality of the drive motor and anti-blocking mechanism and improves control accuracy. Attached Figure Description

A sealing device is installed on the side wall of the limiting block 112. A sealing ring abuts against the inner wall of the adjusting sleeve 111; the lower surface of the limiting block 112 is fixedly connected to the piston rod 113, the piston rod 113 passes through the adjusting column 11 and is fixedly connected to the lower piston 114, the lower surface of the lower piston 114 is fixedly connected to the upper surface of the inner valve plate 115, oil sleeves 116 are provided on both sides of the lower end of the piston rod 113, the lower surface of the inner valve plate 115 is provided with a groove adapted to the anti-blocking mechanism 15, and the inner valve plate 115 and the anti-blocking mechanism 15 are nested together; the drive motor 16 is electrically connected to the valve controller 13, the lower surface of the adjusting column 11 is fixedly connected to the lower valve body 12 through a connecting flange, the two ends of the lower valve body 12 are respectively connected to the pipeline through connecting flanges, the lower end of the lower valve body 12 is equipped with an anti-blocking mechanism 15, and the anti-blocking mechanism 15 is electrically connected to the valve controller 13;

[0047] Specifically, the valve controller 13 receives a control signal and controls the output shaft at the lower end of the drive motor 16 to rotate, which drives the transmission disc 17 to rotate synchronously. This causes the adjusting sleeve 111, which is fixed to the transmission disc, to rotate synchronously. The limiting block 112, which meshes with the adjusting sleeve 111, drives the piston rod 113 to move up and down under the limiting action of the piston rod 113.

The guide sleeve 181 effectively guides the movement of the inner valve plate 115, ensuring the verticality of the movement of the inner valve plate 115, improving the sealing of the piston groove of the valve core 19, and extending the service life of the equipment.

[0048] To address the technical problem of valves becoming clogged due to impurities in the fluid settling inside over time, please refer to [link to relevant documentation]. Figure 4-6 This embodiment provides the following technical solution:

The anti-blocking motor 151 is fixedly connected to the lower surface of the lower valve body 12 by bolts. The upper surface of the anti-blocking motor 151 is fixedly connected to the sealing bushing 152 by a motor shaft. The sealing seat 153 is fixedly connected to the lower surface of the inner valve body 18. The sealing seat 153 and the piston groove of the valve core 19 are on the same center.

The upper surface of the telescopic shaft is fixedly connected to the crushing disc 154.

[0050] The lower surface of the inner valve plate 115 is provided with a placement groove 156 that is adapted to the tension shaft 155.

The upper surface of the crushing disc 154 and the upper surface of the sealing seat 153 form a plane.

[0051] Specifically, depending on the controlled flow rate, the inner valve plate 115 moves upward, the tension shaft 155 drives the crushing disc 154 to move upward, and the sealing sleeve 152 extends and retracts while ensuring the sealing of the piston groove of the valve core 19. The anti-clogging motor 151 rotates, driving the crushing disc 154 to rotate, crushing the impurities in the fluid in the piston groove of the valve core 19. The height of the inner valve plate 115 is further adjusted according to the flow rate, thereby achieving the crushing effect according to the flow rate and achieving the anti-clogging function. This makes the operation more flexible and avoids the crushing disc 154 from running idle when there is a small flow and no blockage, thus extending the service life of the crushing disc 154 and saving energy consumption.

[0052] To better demonstrate the anti-clogging function of the anti-clogging smart valve, please refer to [link / reference]. Figure 7-8 An anti-clogging control system for an anti-clogging intelligent valve, the intelligent valve control system comprising:

[0053] The flow monitoring module is used to acquire the velocity and flow rate data of the fluid inside the smart valve 1, and package the acquired velocity and flow rate data with the basic data of the smart valve 1 to generate a dataset. The dataset is transmitted sequentially to the data processing module for processing based on a time series. The data processing module is used to extract the velocity and flow rate data from the dataset, determine whether the velocity and flow rate data are within a preset value range, and acquire control commands if they exceed or fall below the preset value, and transmit the control commands to the control module.

[0055] Specifically, the intelligent valve control system acquires the flow rate in real time to determine whether the flow rate within the valve body is within the preset range. If normal, it continuously monitors; if abnormal, it controls the inner valve plate 115 to move, adjusting the fluid flow area to achieve the desired control effect. This facilitates adjustment and provides real-time feedback, resulting in high adjustment accuracy. The control module issues valve body control commands and anti-blocking control commands to control the drive motor 16 and the anti-blocking mechanism 15 one by one. As needed, it controls the anti-blocking mechanism 15 to crush impurities in the fluid, providing high adjustment flexibility and improving adjustment accuracy.

If they cannot match, an abnormal alarm is triggered.

[0058] Specifically, the drive motor 16 and the anti-blocking mechanism 15 are periodically woken up by the wake-up module. If the drive motor 16 and the anti-blocking mechanism 15 have not worked for a long time, periodic monitoring is performed. Based on the obtained power consumption characteristics, it is determined whether the drive motor 16 and the anti-blocking mechanism 15 are normal, and abnormal equipment is detected in time.
