In the present specification, a mud scraper control method is provided, and the present specification relates to a mud scraper control apparatus, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Referring to fig. 1, fig. 1 illustrates a schematic view of a scenario of a mud scraper control method according to an embodiment of the present specification.
In the application scenario of fig. 1, the computing device 101 may obtain torque information 102 of the mud scraper via a frequency converter. Then, the computing device 101 performs matching with the moment information 102 according to the preset moment threshold value, and determines a matching result 103.

When the computing device 101 is embodied as software, it may be installed in the hardware devices listed above. It may be implemented as a plurality of software or software modules, for example, for providing distributed services, or as a single software or software module. The present invention is not particularly limited herein.
It should be understood that the number of computing devices in fig. 1 is merely illustrative. There may be any number of computing devices, as desired for an implementation.
Referring to fig. 2, fig. 2 shows a flowchart of a control method of a mud scraper according to an embodiment of the present specification, which specifically includes the following steps.
Step 201: moment information of the mud scraper is obtained through the frequency converter, wherein the mud scraper comprises the frequency converter.
The moment information is moment information of the mud scraper, namely information of rotation moment of the mud scraper, for example, the information of the rotation moment can comprise a value of the rotation moment.
In practical application, the rotary harrow motor of the mud scraper can be changed into a frequency converter for driving control, and the rotation moment of the mud scraper is collected by utilizing the self-provided moment detection function of the frequency converter. The mud scraper rotary motor is controlled and driven by the frequency converter, and the rotation moment of the mud scraper detected by the frequency converter is output to a control system of the control system through 4-20 mA current through menu setting definition. The control system records the revolving moment in real time. Further, referring to fig. 3, fig. 3 shows a system architecture diagram of a control method of a mud scraper, wherein the system architecture diagram comprises a control system, an electric cabinet of the mud scraper, a frequency converter, a main rake rotary motor and a main rake lifting motor. The control system can send an instruction to the electric cabinet of the mud scraper, so that the electric cabinet sends a control signal to the frequency converter of the mud scraper, and the main rake rotary motor is controlled. On the other hand, the control system can send an instruction to the electric cabinet of the mud scraper, so that the electric cabinet can control the main rake lifting motor.
For example, in the process of cleaning sludge, an initial value of rotation moment is set for the sludge scraper, then the sludge scraper starts to scrape the sludge on the tank wall, at this time, as the sludge increases, the moment also starts to increase, and the moment of the sludge scraper can be collected through a frequency converter arranged on the sludge scraper.
In one possible implementation, the acquiring, by the frequency converter, torque information of the mud scraper includes: determining a time range and a time interval in response to the time setting instruction; and in the time range, acquiring the rotation moment value of the mud scraper through the frequency converter at time intervals to obtain moment information of the mud scraper.
Specifically, the time period of collection may be set, and the time interval of collection may also be set.
For example, the time period of collection is set to be eight to eighteen, and the time interval of collection is set to be five seconds once, then the collection of the rotation moment value of the mud scraper is carried out at eight to eighteen points per day every five seconds, and the moment information of the mud scraper is obtained according to the rotation moment value of the mud scraper collected every five seconds.
Step 202: and matching according to the preset moment threshold value and moment information, and determining a matching result.
The preset moment threshold value may be a set threshold value for judging whether to protect the mud scraper.
In one possible implementation manner, matching is performed according to a preset moment threshold value and moment information, and determining a matching result includes: determining a first moment threshold value and a second moment threshold value according to a preset moment threshold value; determining a current turning moment value according to moment information, comparing the current turning moment value with a first moment threshold value, and determining a first comparison result; comparing the current turning moment value with a second moment threshold value under the condition that the first comparison result is that the current turning moment value is larger than the first moment threshold value, and determining a second comparison result; and determining a matching result according to the second comparison result.
The first moment threshold value can be a threshold value which is set and used for reducing the rotation frequency of the mud scraper, and the second moment threshold value can be measures which are further taken for protecting the mud scraper.
In practical application, when the control system detects that the rotation moment of the mud scraper is larger than a first moment threshold value of a set value, the control system automatically sends out to reduce rotation frequency, so that overload of the rotary rake assembly and the driving motor is prevented. When the rotation moment further exceeds the second moment threshold value, the control system increases the rotation frequency in an upward stepping way and lifts the rotation mechanism of the mud scraper by one height, so that the scraping and raking assembly is separated from the accumulated mud, the mud scraping amount is reduced, and the rotation resistance is reduced. Thus, the current rotational torque value needs to be matched to the first torque threshold value and the second torque threshold value in order to determine different protective measures for the mud scraper.
Further, referring to fig. 4, fig. 4 shows a control system diagram of a control method of the sludge scraper, specifically, the sludge scraper is subjected to moment detection, so that the speed of the sludge scraper can be controlled through moment feedback, and meanwhile, the speed of the sludge scraper can be controlled through current feedback of a driving circuit.
For example, the first torque threshold is A1, the second torque threshold is A2, when the mud scraper starts to work, the collection of the rotation torque value of the mud scraper is performed every five seconds, when the control system detects that the current rotation torque value of the mud scraper is greater than A1, whether the current rotation torque value is greater than A2 is judged, and it is determined that the current rotation torque value is between A1 and A2, or the current rotation torque value is greater than A2.
Step 203: and controlling the mud scraper through the frequency converter according to the matching result.
In practical application, the center-driven sludge scraper drives the rotary rake to slowly rotate and scrape the sludge deposited on the tank wall through the rotary motor, and the sludge is collected into the bottom sludge collecting pit. When the sludge is accumulated to a certain extent, a sludge discharge pipe pump is started to discharge the sludge. The central transmission mud scraper controls the up-and-down motion of the rotary harrow to adjust the contact depth with the mud through the lifting motor.
In one possible implementation, controlling the mud scraper by the frequency converter according to the matching result includes: when the second comparison result is that the current rotation moment value is smaller than the second moment threshold value, sending a frequency reducing instruction to the mud scraper so as to reduce the rotation frequency of the mud scraper through the frequency converter; and under the condition that the second comparison result is that the current rotation moment value is larger than the second moment threshold value, sending a frequency reducing instruction and a first mechanism lifting instruction to the mud scraper so as to reduce the rotation frequency of the mud scraper and lift the height of the rotation mechanism through the frequency converter.
In practical application, the normal no-load turning moment of the mud scraper is a first moment threshold. As the sludge is gradually increased, the resistance of the slewing mechanism is gradually increased, and when the detected slewing torque exceeds a second torque threshold value of a preset allowable torque value, a control system sends a command for reducing the rotating speed of the rotary rake to the frequency converter so as to prevent the motor from being overloaded. After the rotation speed of the rotary driving motor is reduced by the control system, when the moment of the rotary mechanism continuously rises until the moment exceeds a fourth moment threshold value of a preset moment value, the control system sends a lifting signal to step up the rotary harrow of the mud scraper, so that the contact depth of the harrow and the mud is reduced, and the moment of the rotary mechanism is reduced to be below the fourth moment threshold value.
For example, when the mud scraper starts to work, the rotation moment value of the mud scraper is collected every five seconds, when the control system detects that the current rotation moment value of the mud scraper is larger than A1, whether the current rotation moment value is larger than A2 is judged, the current rotation moment value is determined to be between A1 and A2, then an instruction for reducing the rotation speed of the rotary rake is sent to a frequency converter of the mud scraper, and overload of a motor is prevented.
For example, when the mud scraper starts to work, the rotation moment value of the mud scraper is collected once every five seconds, when the control system detects that the current rotation moment value of the mud scraper is larger than A1, whether the current rotation moment value is larger than A2 or not is judged, an instruction for reducing the rotation speed of the rotary harrow is sent to a frequency converter of the mud scraper, and an instruction for lifting the rotary harrow of the mud scraper is sent to the mud scraper, so that the contact depth of the harrow and mud is reduced.
Specifically, the above instruction for lifting the rotating rake of the mud scraper to the mud scraper may be a gradual lifting method, for example, lifting the rotating rake of the mud scraper first, detecting the current value of the rotation moment of the mud scraper, continuously judging that the current value of the rotation moment is greater than A2, and continuously lifting the rotating rake of the mud scraper if the current value of the rotation moment is greater than A2 until the current value of the rotation moment is not greater than A2.
Further, the heights of the rotating harrows of the scraper can be inconsistent each time, for example, the rotating harrow of the scraper is lifted for the first time to be L1, then the value of the current rotation moment of the scraper is detected, the value of the current rotation moment is continuously judged to be larger than A2, and if the value of the current rotation moment is larger than A2, the rotating harrow of the scraper is continuously lifted to be L1 until the value of the current rotation moment is not larger than A2.
In one possible implementation, after controlling the mud scraper through the frequency converter according to the matching result, the method further includes: and sending a sludge discharge instruction to the sludge discharge equipment so as to enable the sludge discharge equipment to reduce the thickness of the sludge.
Furthermore, linkage mud discharging can be performed, wherein the linkage mud discharging means that the control system sends a command for reducing the rotating speed of the rotary rake to the frequency converter, so that overload of the motor is prevented. Meanwhile, a mud discharging instruction is sent to mud discharging equipment to discharge mud, and the rotary mud scraping moment is reduced.
For example, when the mud scraper starts to work, the rotation moment value of the mud scraper is collected every five seconds, when the control system detects that the current rotation moment value of the mud scraper is larger than A1, whether the current rotation moment value is larger than A2 is judged, the current rotation moment value is determined to be between A1 and A2, then an instruction for reducing the rotation speed of the rotary rake is sent to a frequency converter of the mud scraper, and overload of a motor is prevented. Simultaneously, a mud discharging instruction is sent to mud discharging equipment, wherein the mud discharging equipment can be a mud discharging pipeline, and mud is sucked out through a mud discharging pump, so that linkage mud discharging is realized.
It should be noted that the scheme of sending a sludge discharge instruction to the sludge discharge device and lifting the rotary rake of the sludge scraper can be combined.
When the control system detects that the current value of the rotation moment of the mud scraper is larger than A1, judging whether the current value of the rotation moment is larger than A2 or not, sending a command for reducing the rotating speed of the rotary harrow to a frequency converter of the mud scraper, and simultaneously sending a command for lifting the rotary harrow of the mud scraper to the mud scraper, thereby reducing the contact depth of the harrow and mud. And a mud discharging instruction is sent to mud discharging equipment, so that linkage mud discharging is realized.
In one possible implementation, after controlling the mud scraper through the frequency converter according to the matching result, the method further includes: determining a third moment threshold according to a preset moment threshold; determining a current rotation moment value according to the moment information, comparing the current rotation moment value with a third moment threshold value, and determining a third comparison result; and sending a frequency lifting instruction to the mud scraper under the condition that the third comparison result is that the current rotation moment value is smaller than a third moment threshold value, so that the rotation frequency of the mud scraper is improved through the frequency converter.
In practical application, when the detected rotation moment is lower than the third moment threshold of the set moment, the control system sends out an instruction to start stepping to reduce the rotation mechanism, increase the mud eating amount of the scraping mechanism and stop the mud discharging equipment. Correspondingly, the rotation frequency of the mud scraper can be increased and the mud discharging equipment can be stopped.
For example, when the mud scraper starts to work, the rotation moment value of the mud scraper is collected every five seconds, and when the control system detects that the current rotation moment value of the mud scraper is smaller than A3, an instruction for increasing the rotation speed of the rotary rake can be sent to the frequency converter of the mud scraper, and an instruction for reducing the rotary rake of the mud scraper is sent to the mud scraper, so that the contact depth of the rake and the mud is increased. And a mud discharging instruction is sent to mud discharging equipment, so that the mud eating amount of the scraping and raking mechanism is increased.
In one possible implementation, after controlling the mud scraper through the frequency converter according to the matching result, the method further includes: determining a fourth moment threshold according to a preset moment threshold; determining a current rotation moment value according to the moment information, comparing the current rotation moment value with a fourth moment threshold value, and determining a fourth comparison result; and under the condition that the fourth comparison result is that the current rotation moment value is larger than the fourth moment threshold value, sending a second mechanism lifting instruction to the mud scraper so as to enable the mud scraper to lift the height of the rotary harrow, and sending a warning signal.
For example, when the mud scraper starts to work, the rotation moment value of the mud scraper is collected once every five seconds, when the control system detects that the current rotation moment value of the mud scraper is larger than A1, whether the current rotation moment value is larger than A2 or not is judged, an instruction for reducing the rotation speed of the rotary harrow is sent to a frequency converter of the mud scraper, and an instruction for lifting the rotary harrow of the mud scraper is sent to the mud scraper, so that the contact depth of the harrow and mud is reduced. And a mud discharging instruction is sent to mud discharging equipment. When the rotary rake of the lifting mud scraper reaches the set height L1 and the current value of the turning moment continues to rise to be more than A4, the rotary rake of the lifting mud scraper reaches the set height L2, and an alarm signal is sent to an alarm system to prompt a worker to process.

The method comprises the steps of acquiring moment information of the mud scraper through the frequency converter, wherein the mud scraper comprises the frequency converter, matching the moment threshold with the moment information according to the preset moment threshold, determining a matching result, and controlling the mud scraper through the frequency converter according to the matching result, so that the working state of the mud scraper can be automatically controlled according to the moment information, damage and the like of the mud scraper are prevented, and the service life of the mud scraper is prolonged.
Furthermore, the moment measuring mode of the rotary mechanism of the mud scraper is changed, the original mechanical moment measuring mechanism with insufficient precision and poor reliability is transformed into the moment accurate measurement which is controlled by a frequency converter, and an electric excitation model of the rotary motor is established through the frequency converter. And a control model based on dynamic change of the turning moment of the scraper is built in the control system, so that linkage speed reduction is realized, equipment is started to discharge mud, and the motor is controlled not to be overloaded. The rake is lifted and lowered in a stepping mode according to the further change of the rotation moment in real time, the mud scraping amount is accurately adjusted through the change of the height of the rake scraping assembly, and the moment is controlled within a set range. By the implementation of the function, the abnormality that the sludge scraper is stopped and equipment is damaged due to overload of the sludge pressing rake and the rake component of the wastewater treatment concentration tank is effectively solved.
