The rotating head 41 produces a continuous rotation effect under the cooperation of the centrifugal force of the turning branch pipe 42 and the rotating nozzle 43 and the reaction force generated by the inner wall of the carbon steel square tube, thereby being able to achieve a high-pressure rotary cleaning effect on the inner wall of the carbon steel square tube, which can effectively promote the cleaning effect and cleaning efficiency, reduce the generation of cleaning dead corners, and can also produce an automatic rotation effect through water pressure cooperation, effectively reducing the energy loss in the cleaning process, while reducing the cleaning cost, and effectively improving the environmental protection of the cleaning process.

The output end of the intelligent cleaning processing unit is also connected to a shunt control unit, and the output end of the shunt control unit is connected to the electromagnetic flow valve signal. The setting of the auxiliary nozzle 53 can effectively assist the rotation cleaning method of the rotating cleaning component 4.

The flushing cleaning effect of the four corners improves the cleaning effect of the corners, avoids the occurrence of cleaning dead corners, reduces the number of repeated cleaning, and further improves the cleaning effect and cleaning efficiency. The setting of the diversion control unit can effectively coordinate the cooperation between the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5, thereby ensuring the cleaning effect of the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5, improving their mutual cooperation, and improving the cleaning effect. It can also reduce the loss of cleaning resources and reduce cleaning costs, ensure the environmental protection of the cleaning process, and promote the economic benefits of cleaning carbon steel square tubes.

[0045] Figure 2It is shown that the output end of the intelligent cleaning processing unit is also connected to a cleaning regulation and compensation unit, and the output end of the cleaning regulation and compensation unit is connected to the cleaning regulation unit signal. The setting of the cleaning regulation and compensation unit can effectively realize the role of intelligent regulation of the pumping pressure of the cleaning pump 12 through the cleaning regulation unit during the cleaning process, and can effectively cooperate with the role of the diversion regulation unit.

[0047] Second implementation method:

[0048] Figure 1 - Fig.12 A pipe inner wall cleaning device for processing carbon steel square pipes is shown, and the electromagnetic displacement component 6 includes a movable sleeve 61, and the left and right ends of the movable sleeve 61 are fixedly connected with a movable sleeve head 62, and the movable sleeve head 62 is fixedly connected with a sleeve head grasping foot 63 at one end close to the auxiliary cleaning tube 51, the sleeve head grasping foot 63 on the left side is fixedly connected to the auxiliary cleaning tube 51 at one end away from the movable sleeve head 62, and the sleeve head grasping foot 63 on the right side is abutted against the telescopic cleaning tube 2 at one end away from the movable sleeve head 62, and is in sliding cooperation with the telescopic cleaning tube 2. The cooperation of the two sleeve head grasping feet 63 can effectively realize the traction and release of the telescopic cleaning tube 2 during the cleaning process, and effectively realize the function and effect of the movable sleeve 61 driving the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5 to move.

[0049] Figure 3 - Figure 7It is shown that a moving cavity is opened in the moving sleeve 61, and electromagnetic displacement blocks 64 are fixedly connected to the left and right inner walls of the moving cavity. An isolation spring 65 is fixedly connected between the two electromagnetic displacement blocks 64, and the output end of the displacement control unit is connected to the electromagnetic displacement block 64 signal. The cooperation between the electromagnetic displacement block 64 and the displacement control unit can effectively realize automatic control of the movement process of the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5 on the inner wall of the carbon steel square tube, which can meet the needs of carbon steel square tubes with different placement methods, improve the adaptability of the cleaning process, and effectively promote the cleaning efficiency while promoting the cleaning effect, thereby reducing the difficulty of positioning the carbon steel square tube during cleaning.

[0050] Figure 3 - Figure 7 The displacement auxiliary component 7 is shown to include a tension support foot 71 fixedly connected to the end of the movable sleeve 62 away from the auxiliary cleaning cylinder 51, the tension support foot 71 is made of elastic material, and a plurality of friction blocks 75 are embedded in the end of the tension support foot 71 away from the auxiliary cleaning cylinder 51. A tension cavity 72 is provided in the tension support foot 71, and a tension bronchial tube 73 connected thereto is fixedly connected to the lower end of the tension cavity 72. The lower end of the tension bronchial tube 73 extends to the outside of the tension support foot 71, and passes through the movable sleeve 62 and the sleeve gripping foot 63 and is fixedly connected to a tension main air pipe 74 connected thereto. The right end of the tension main air pipe 74 is connected to the The air pressure control structure is connected, and the output end of the support foot control unit is respectively connected to the tension solenoid valve installed on the tension bronchial pipe 73 and the air pressure control structure signal. The cooperation between the tension support foot 71, the movable sleeve 61 and the electromagnetic displacement block 64 effectively realizes the automatic positioning and displacement control on the inner wall of the carbon steel square tube. While ensuring the cleaning angle and position of the four-corner auxiliary cleaning assembly 5 in the carbon steel square tube, it can also achieve the effect of smooth movement of the rotating cleaning assembly 4 and the four-corner auxiliary cleaning assembly 5 on the inner wall of the carbon steel square tube, and is therefore suitable for the cleaning of the inner wall of the carbon steel square tube with different settings.

[0051] Figure 1 - Fig.12 It is shown that when the inner wall of the carbon steel square tube needs to be cleaned, the cleaning personnel or technicians input the cleaning parameters to the cleaning parameter setting unit through the control buttons on the cleaning control box 11 according to the specification status of the carbon steel square tube. These parameters include but are not limited to the cleaning pressure, cleaning time, cleaning length and other data related to the cleaning of the inner wall of the carbon steel square tube. Then, the cleaning parameter setting unit converts the cleaning data and transmits it to the intelligent cleaning processing unit. The intelligent cleaning processing unit analyzes and processes these data, and then executes the data instructions of the parameter setting in the subsequent control process;

[0052] The cleaning staff holds the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5 and inserts them into the carbon steel square tube that has been placed, and makes the displacement auxiliary components 7 on the upper and lower sides of the auxiliary cleaning cylinder 51 all enter the carbon steel square tube, and then starts to send an instruction to the cleaning parameter setting unit to start the cleaning program through the control button. After receiving the instruction, the intelligent cleaning processing unit sends an instruction to the support leg control unit. The support leg control unit controls the tension solenoid valves in the four tension bronchial tubes 73 to open, and controls the air pressure control structure to intake air into the tension bronchial tube 73 through the tension main air pipe 74, so that the tension bronchial tube 73 is The tube 73 guides air into the tension chamber 72, causing the tension leg 71 to swell and deform. The tension leg 71 continues to expand, and the end of the tension leg 71 away from the auxiliary cleaning cylinder 51 abuts against the inner wall of the carbon steel square tube, and increases the friction force through the friction block 75 to ensure the positioning effect of the tension leg 71. Then the leg pressure probe located in the tension leg 71 transmits the leg pressure data to the displacement data feedback unit, and the displacement data feedback unit transmits the data to the intelligent cleaning processing unit. The intelligent cleaning processing unit determines that the positioning of the tension leg 71 is completed at this time, and transmits it to the leg control unit. The tension electromagnetic valve on the tension bronchial pipe 73 is closed to maintain the pressure in the tension chamber 72, maintain the inflation effect of the tension support leg 71, maintain the abutment and positioning effect of the tension support leg 71 and the friction block 75 with the inner wall of the carbon steel square tube, and then close the air intake effect of the air pressure control structure to complete the positioning and fixing effect of the tension support leg 71, so that the cleaning personnel stay away from the carbon steel square tube to avoid the subsequent splashing of the cleaning liquid and affecting the cleaning personnel. At the same time, the intelligent cleaning processing unit will also send a control instruction to the diversion control unit, so that the separation control unit controls the electromagnetic flow valve located in the auxiliary nozzle 53 to Flow control, when it is located at the end of the inner wall of the carbon steel square tube and in the initial stage of cleaning, the electromagnetic flow valve in the auxiliary nozzle 53 is controlled to be a parameter control with a smaller flow rate to ensure the cleaning pressure in the rotating head 41 at this time, promote the rotating head 41 to rotate under the centrifugal force of the turning branch pipe 42 and the reaction force of the inner wall of the carbon steel square tube, promote the cleaning effect of the inner wall of the carbon steel square tube end at this time, ensure the effect of the subsequent movement of the electromagnetic displacement component 6 and the displacement auxiliary component 7, avoid the contamination of the displacement auxiliary component 7 by impurities on the inner wall of the carbon steel square tube, and ensure the positioning stability of the tension support foot 71;

[0053] Then the intelligent cleaning processing unit sends a cleaning control instruction to the cleaning control unit to start the cleaning pump 12. The cleaning pump 12 transports the cleaning liquid into the telescopic cleaning tube 2, and then continuously enters the rotating cleaning component 4 and the four-corner auxiliary cleaning component 5 under the guidance of the pipe joint 3. After the cleaning liquid continuously enters the auxiliary cleaning cylinder 51 and the rotating head 41, a small amount of cleaning liquid will enter the auxiliary nozzle 53 through the electromagnetic flow valve, so that the auxiliary nozzle 53 flushes and cleans the four corners of the inner wall of the carbon steel square tube. A larger amount of cleaning liquid will flow into the turning branch pipe 42 through the rotating head 41, and then be discharged through the rotating nozzle 43. On the one hand, it can promote the rotation of the rotating head 41, and at the same time, it can also perform high-pressure cleaning on the inner wall of the carbon steel square tube while rotating, thereby improving the cleaning effect at this time.

[0054] After cleaning is started, the cleaning pressure probes located in the rotating head 41 and the auxiliary cleaning cylinder 51 will transmit the pressure data in the rotating head 41 and the auxiliary cleaning cylinder 51 to the cleaning pressure feedback unit. The cleaning pressure feedback unit transmits the dual pressure data to the intelligent cleaning processing unit. The intelligent cleaning processing unit judges and processes the dual pressure data. When it is judged that the pressure in the rotating head 41 at this time is less than the set cleaning pressure, the cleaning compensation data is transmitted to the cleaning regulation and compensation unit. The cleaning regulation and compensation unit transmits the compensation regulation data to the cleaning regulation unit. The cleaning regulation unit controls the cleaning pump 12 to generate a pressurization effect to promote the pressure of the cleaning liquid entering the rotating head 41. Then the cleaning pressure probes located in the rotating head 41 and the auxiliary cleaning cylinder 51 continue to transmit the pressure data to the intelligent cleaning processing unit through the cleaning pressure feedback unit. The intelligent cleaning processing unit again The intelligent cleaning processing unit transmits the instruction of shunt control to the shunt control unit, and controls the electromagnetic flow valve to increase the flow rate through the shunt control unit, so that the auxiliary nozzle 53 can produce a larger liquid spray cleaning effect, and effectively play the effect of shunt pressure reduction, while ensuring the cleaning effect of the rotating cleaning component 4, reducing the damage caused by pressure, and then the intelligent cleaning processing unit judges the effectiveness of the control according to the dual pressure data transmitted and fed back by the cleaning pressure feedback unit;

[0055] After the intelligent cleaning processing unit completes the regulation of the cleaning pressure, it continues to send regulation instructions to the support leg regulation unit, so that the support leg regulation unit at this time controls the tension solenoid valves of the two tension bronchial pipes 73 located at the outer end of the auxiliary cleaning cylinder 51 to open, and produces a pressure relief effect under the cooperation of the air pressure regulation structure and the tension main air pipe 74, so that the air in the tension chamber 72 is discharged through the tension bronchial pipe 73 and the tension main air pipe 74, so that the tension support leg 71 produces a recovery deformation. Therefore, at this time, the two tension support legs 71 located at the outer end of the auxiliary cleaning cylinder 51 do not contact the inner wall of the carbon steel square tube. After receiving the pressure data in the two tension support legs 71 at the outer end of the auxiliary cleaning cylinder 51 transmitted by the displacement data feedback unit, the intelligent cleaning processing unit determines that after the pressure relief is completed, and sends a regulation instruction to the support leg regulation unit. The displacement control unit sends out a control instruction, and the displacement control unit passes current into the two electromagnetic displacement blocks 64 in the movable sleeve 61, so that the two 54 produce repulsive electromagnetic forces, causing the movable sleeve 61 to extend and deform, and then under the action of the two tension legs 71 located at the outer end of the telescopic cleaning tube 2 maintaining abutment and positioning with the inner wall of the carbon steel square tube, and the sleeve head grasping foot 63 and the telescopic cleaning tube 2 slidingly cooperate, the elongation deformation of the movable sleeve 61 can drive the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5 to produce a forward displacement in the carbon steel square tube, and in the process of moving, the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5 still maintain an effective cleaning effect. After the deformation of the movable sleeve 61 is completed, the intelligent cleaning processing unit controls the leg control unit 71 to move the movable sleeve 61 forward. The element produces a continuous control effect, so that the air pressure control structure transmits gas to the tension cavity 72 of the two tension support legs 71 located at the outer end of the auxiliary cleaning cylinder 51 through the tension main air pipe 74 and the tension bronchial pipe 73, so that the tension support legs 71 produce an air expansion effect, and then maintain the abutment effect with the inner wall of the carbon steel square tube with the cooperation of the friction block 75. After the intelligent cleaning processing unit transmits the pressure data in the tension cavity 72 through the displacement data feedback unit, it is judged that the abutment is completed, and the tension solenoid valves on the two tension bronchial pipes 73 located at the outer end of the auxiliary cleaning cylinder 51 are closed through the support leg control unit to ensure the air expansion abutment effect in the tension support legs 71 at this time, and then the tension solenoid valves on the two tension bronchial pipes 73 located at the outer end of the telescopic cleaning tube 2 are opened so that they are in contact with the tension. The main air pipe 74 is connected to the main air pipe 74, and the pressure relief effect is generated in the tension chamber 72 of the two tension legs 71 located at the outer end of the telescopic cleaning tube 2 through the air pressure control structure, so that the tension legs 71 are restored and contacted with the inner wall of the carbon steel square tube for positioning. The intelligent cleaning processing unit receives the pressure data in the two tension legs 71 located at the outer end of the telescopic cleaning tube 2 transmitted by the displacement data feedback unit, and after judging that the pressure relief is completed, it sends a control instruction to the displacement control unit, so that the displacement control unit controls the two electromagnetic displacement blocks 64 in the same movable sleeve 61 to generate an electromagnetic force of attraction, so that the movable sleeve 61 is contracted and deformed. Under the action of the two tension legs 71 located at the outer end of the auxiliary cleaning tube 51 being kept in contact with the inner wall of the carbon steel square tube for positioning,The sleeve head gripping foot 63 and the telescopic cleaning tube 2 are in sliding cooperation. The contraction of the movable sleeve 61 can drive the two tension legs 71 located at the outer end of the telescopic cleaning tube 2 to produce deformation to restore the position, and continuously approach the side of the pipe joint 3. After the movable sleeve 61 completes the contraction deformation, the intelligent cleaning processing unit continues to control the leg regulating unit to function. In this way, the two tension legs 71 located at the outer end of the auxiliary cleaning cylinder 51 and the two tension legs 71 located at the outer end of the telescopic cleaning tube 2 are continuously inflated and deflated, and the extension and contraction adjustment of the movable sleeve 61 are coordinated to effectively realize the effect of the rotating cleaning component 4 and the four-corner auxiliary cleaning component 5 continuously moving in the carbon steel square tube, which can effectively realize the complete cleaning effect on the inside of the longer carbon steel square tube.

[0056] Then, while the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5 are continuously moved in the carbon steel square tube under the action of the electromagnetic displacement component 6 and the displacement auxiliary component 7, and the inner wall of the carbon steel square tube is cleaned, the intelligent cleaning processing unit will also send control instructions to the cleaning regulation and compensation unit and the diversion regulation unit. During the continuous forward movement of the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5, compensation regulation data is sent to the cleaning regulation unit through the cleaning regulation and compensation unit, so that the cleaning regulation unit continuously increases the power of the cleaning pump 12, increases the pressure of the cleaning liquid pumped into the telescopic cleaning tube 2, increases the cleaning pressure of the rotating cleaning component 4 and the four-corner auxiliary cleaning components 5, and then the diversion regulation unit is connected to the electromagnetic displacement component 6 and the displacement auxiliary component 7. The magnetic flow valve is controlled to increase the control of the electromagnetic flow valve on the flow of cleaning liquid in the auxiliary nozzle 53, increase the cleaning pressure and spray volume of the auxiliary nozzle 53, and promote the cleaning effect. At the same time, it can also clean and export impurities in the carbon steel square tube through the continuously increasing cleaning pressure, avoid the accumulation of cleaning impurities, cause subsequent cleaning defects and poor movement of the rotating cleaning component 4 and the four-corner auxiliary cleaning component 5, effectively ensure the cleaning efficiency, promote the cleaning effect, and can also effectively realize the environmental protection of the cleaning process through the control of the cleaning pressure and the auxiliary cleaning flow during the cleaning process, reduce the loss and waste of the cleaning liquid, reduce the cost of cleaning the inner wall of the carbon steel square tube, and promote the economic benefits of carbon steel square tube processing.

[0057] Finally, in the process of continuous cleaning, the intelligent cleaning processing unit will output the relevant data of this cleaning through the cleaning data output unit. On the one hand, it will display the real-time cleaning status to the cleaning personnel or technicians through the display located in the cleaning control box 11, and on the other hand, it will save the cleaning records through the memory, which can not only play the role of data tracing, but also provide technical personnel with data support for subsequent improvement of cleaning parameters, realize the continuous development of cleaning process methods, and improve the cleaning quality of carbon steel square tubes to ensure the quality and safety of subsequent carbon steel square tube applications. In addition, in the cleaning process, the intelligent cleaning processing unit judges the transmission data of the cleaning pressure feedback unit and the displacement data feedback unit, and in the event of abnormal cleaning pressure, including but not limited to the state where the pressure in the rotating head 41 is too low and the pressure in the auxiliary cleaning cylinder 51 is high, and the rotating head 41 If the pressure in the auxiliary cleaning cylinder 51 is too small, it means that there are abnormalities in the sealing connection between the rotating head 41 and the auxiliary cleaning cylinder 51, the sealing connection between the auxiliary cleaning cylinder 51 and the pipe joint 3, the sealing connection between the pipe joint 3 and the telescopic cleaning tube 2, and the sealing goodness of the telescopic cleaning tube 2 and the cleaning pump 12. If the pressure of the tension support foot 71 remains unchanged after the pressure is relieved and the pressure of the tension support foot 71 remains unchanged when the air is taken in, it means that the tension support foot 71 has a sealing abnormality. The intelligent cleaning processing unit will display and store the abnormal data through the cleaning data output unit, and will also send an abnormal instruction to the cleaning abnormality warning unit, so that the cleaning abnormality warning unit controls the alarm to start, and sends an abnormal reminder to the cleaning staff or technicians, so that the cleaning staff or technicians can shut down the cleaning operation in time and inspect and maintain the device.

[0058] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
