Description

Technical Field

[0001] This invention relates to the field of surface treatment technology for cable protection pipes, specifically to an intelligent surface treatment device for cable protection pipes and its usage method. Background Technology

[0002] Cable protection pipes are key components ensuring the safe operation of underground power and communication lines, and the quality of their surface treatment directly determines the adhesion and service life of the anti-corrosion coating. In particular, the cleanliness of the pipe's inner wall affects not only the uniformity and density of the coating but also the smoothness of subsequent cable installation and long-term operational reliability. Therefore, thoroughly and evenly cleaning the inner wall of the cable protection pipe is a core process for ensuring the overall quality of the product.

[0003] However, existing surface treatment devices have significant shortcomings in practical applications. Due to the slender shape of the pipes and poor visibility of the inner cavity, traditional direct-jet spray bars or extended nozzles cannot evenly cover the entire inner wall with the cleaning medium, especially in the middle and far-end areas of the pipes, which easily creates cleaning dead zones, resulting in the residue of oxide scale, welding slag, or dust. The presence of these residues will directly reduce the adhesion of the anti-corrosion layer on the inner wall, causing early corrosion, and may even scratch the cable sheath during cable installation, seriously threatening the operational safety of the line.

[0004] Therefore, it is necessary to provide an intelligent cable protection pipe surface treatment device and its usage method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent cable protection pipe surface treatment device and its usage method, which can perform uniform, efficient and controllable cleaning operations on the inner wall of the cable protection pipe, and monitor the cleaning effect in real time, thereby improving the cleaning quality and solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent cable protection pipe surface treatment device, comprising a cleaning mechanism, a feeding mechanism, a positioning component, and a surface treatment mechanism.

The end of the water passage away from the water inlet pipe is connected to the nozzle through a pipe. The pipe connecting the water passage and the nozzle passes through the bracket three.

[0010] According to the above technical solution, the second bracket is hollow in the middle and is located between the support cylinder and the third bracket. The two ends of the second bracket are rotatably connected to the support cylinder and the third bracket, respectively. The connection between the third bracket and the support cylinder is located inside the hollow part of the second bracket. The output end of the first drive unit passes through the support cylinder. The three sets of cylinders are fixed at equal intervals on the bracket two along the axis of the support cylinder, and the movable block is provided with a slope around the side near the limiting groove.

[0011] According to the above technical solution, the camera is fixed at the end of the nozzle away from the bracket three. The camera is connected to a surface treatment module, which is also connected to a pressure sensor. The surface treatment module is used to acquire the camera's image, determine the cleaning quality of the inner wall of the cable protection pipe, and acquire the pressure change when the cleaning block cleans the inner wall of the cable protection pipe. In this way, the cleaning pressure and cleaning mode are adjusted to ensure uniform and thorough cleaning of the inner wall of the cable protection pipe and improve the cleaning quality.

[0012] According to the above technical solution, the drive assembly includes a second drive unit, the output end of the second drive unit is connected to a corresponding connecting shaft, a fourth bracket is sleeved on the outside of the second drive unit, three sets of third cylinders are fixedly connected to the outside of the fourth bracket, an arc-shaped support plate is fixedly connected to the output end of the third cylinder, and support rollers are installed at both ends of the arc-shaped support plate. The support component and the drive component have the same structural configuration, except that the support component is not driven by the second drive unit.

[0013] According to the above technical solution, the cleaning mechanism includes a soaking tank, a rinsing tank, and a rinsing assembly. The soaking tank and the rinsing tank are arranged side by side and connected to each other. A drain outlet one is provided at the bottom of the side of the soaking tank away from the rinsing tank. A drain outlet two is provided on the side of the rinsing tank connected to the soaking tank. The drain outlet two is connected to the inside of the soaking tank. Both the drain outlet one and the drain outlet two are equipped with electrically controlled valves. Both the soaking tank and the rinsing tank are equipped with turbidity meters, and several ultrasonic transducers are fixedly connected inside the soaking tank. The shower assembly includes a support frame and several spray heads. The support frame is fixed on the shower tank, and the spray heads are fixed on the support frame. All the spray heads are arranged facing the shower tank, and each spray head is connected to a liquid pump.

[0014] According to the above technical solution, the feeding mechanism includes a conveyor belt and several feeding plates.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention, by setting up a cleaning mechanism, can utilize the drain outlet and electrically controlled valve set between the soaking tank and the rinsing tank, and cooperate with the turbidity meter for real-time monitoring, to directly discharge the dirtier soaking water from the soaking tank, while the relatively clean rinsing water is automatically replenished into the soaking tank by relying on the liquid level difference, thereby reducing the total amount of waste liquid discharged, and at the same time reducing the energy consumption of the replenishment equipment and operation. Equipped with a surface treatment mechanism, the device utilizes a spiral propulsion structure to continuously move within the pipe. Combined with a camera for initial inspection, secondary confirmation, and localized re-washing of cleaned areas, it achieves continuous cleaning of the entire pipe length without blind spots. A pressure sensor within the limiting groove monitors the contact pressure of the cleaning block against the pipe wall in real time and feeds the data back to the surface treatment module. Dynamic pressure adjustment is achieved by controlling cylinder two, preventing excessive pressure from damaging the pipe wall or excessively abrading the cleaning block, while also avoiding insufficient pressure leading to missed areas, thus achieving flexible cleaning. Furthermore, different combinations of water washing and air spraying modes can be used to address cleaning challenges of varying difficulty, enabling uniform, efficient, and controllable cleaning of the inner wall of the cable protection pipe, thereby improving cleaning quality.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-10 The present invention provides a technical solution: an intelligent cable protection pipe surface treatment device, comprising a cleaning mechanism 1, a feeding mechanism 2, a positioning component 3, and a surface treatment mechanism; the cleaning mechanism 1 is used to soak and ultrasonically clean the cable protection pipe, the feeding mechanism 2 is used to convey the cable protection pipe after soaking and ultrasonic cleaning, and the positioning component 3 is used to support and clamp the cable protection pipe, so as to facilitate the surface treatment mechanism to perform external wall spraying, internal cleaning, and internal wall cleaning quality inspection on the cable protection pipe.

[0019] Specifically, such as Figure 1 and Figure 2As shown, the cleaning mechanism 1 includes an soaking tank 11, a rinsing tank 13, and a rinsing assembly. The soaking tank 11 and the rinsing tank 13 are arranged side by side and connected to each other. A drain outlet 12 is provided at the bottom of the side of the soaking tank 11 away from the rinsing tank 13. A drain outlet 14 is provided on the side of the rinsing tank 13 connected to the soaking tank 11. The drain outlet 14 is connected to the inside of the soaking tank 11. Both the drain outlet 12 and the drain outlet 14 are equipped with electrically controlled valves. The soaking tank 11 is used to contain the cleaning solution for soaking and cleaning the cable protection pipe. The rinsing tank 13 is used to contain the cleaning solution for spraying the cable protection pipe. The electrically controlled valves are opened to drain the soaking water inside the soaking tank 11 and to drain the rinsing water in the rinsing tank 13 into the soaking tank 11. Both the soaking tank 11 and the rinsing tank 13 are equipped with turbidity meters 16. The turbidity meters 16 are used to detect the turbidity of the cleaning solution inside the soaking tank 11 and the rinsing tank 13, so as to facilitate subsequent judgment on whether the cleaning solution inside the soaking tank 11 needs to be replaced or replenished. Several ultrasonic transducers 15 are fixedly connected inside the soaking tank 11 for ultrasonic cleaning of the cable protection pipe soaked inside the soaking tank 11, thereby improving the quality of soaking and cleaning and reducing the difficulty of subsequent cleaning of the inner wall of the cable protection pipe. Furthermore, such as Figure 2 As shown, the shower assembly includes a support frame 17 and several spray heads 18. The support frame 17 is fixed on the shower tank 13, and the several spray heads 18 are fixed on the support frame 17. The several spray heads 18 are all arranged facing the shower tank 13. The spray heads 18 are connected to a liquid pump, which is located in a clean water tank. The clean water tank is used to hold unused cleaning liquid or the cleaning liquid filtered from the shower tank 13.

[0020] It should be noted that after the electrically controlled valve on drain outlet 12 is opened to discharge the highly turbid cleaning solution inside soaking tank 11, the electrically controlled valve on drain outlet 12 is closed, and the electrically controlled valve on drain outlet 14 is opened. By utilizing the liquid pressure difference inside shower tank 13, the cleaning solution inside shower tank 13 is discharged into soaking tank 11, reducing the equipment required for liquid supply and improving the efficiency and flexibility of cleaning solution use.

[0021] Specifically, such as Figure 2 and Figure 3 As shown, the feeding mechanism 2 includes a conveyor belt 21 and several feeding plates 22. The conveyor belt 21 is inclined and its lower end is located in the soaking tank 11. Several feeding plates 22 are equidistantly arranged on the conveyor belt 21. Limiting posts 23 are fixedly connected to both sides of the conveyor belt 21. Movable grooves are opened on the limiting posts 23. Limiting baffles 24 are provided between the two sets of limiting posts 23. Fasteners are provided in the movable grooves and are fixedly connected to the limiting baffles 24. The fasteners are used to fix the limiting posts 23 between the two sets of limiting baffles 24 after adjusting the height and angle of the limiting posts 23.

[0022] It should be noted that the fasteners can be bolts and nuts, or other components that serve a fastening function. The limit post 23 and the fasteners can also be other components that can adjust the height, angle and fix the limit baffle 24.

[0023] Specifically, the positioning component 3 includes two sets of lifting columns 31 and two sets of electric grippers 32. The two sets of lifting columns 31 are installed inside the soaking tank 11, and the two sets of electric grippers 32 are fixed to the top of the lifting columns 31 respectively. The lifting columns 31 are used to adjust the height of the electric grippers 32, and the electric grippers 32 are used to clamp the cable protection tube.

[0024] In practical use, the staff adjusts the height and angle of the limiting baffle 24 according to the size of the cable protection pipe, so that the distance between the limiting baffle 24 and the conveyor belt 21 is only enough for one set of cable protection pipes to pass through. Then, the cable protection pipes are placed in the soaking tank 11, and the ultrasonic transducer 15 is turned on to soak and ultrasonically clean the cable protection pipes. After soaking for a certain period of time, the conveyor belt 21 is turned on. When the feeding plate 22 on the conveyor belt 21 moves to the bottom of the soaking tank 11, the feeding plate 22 extends between the stacked cable protection pipes. As the conveyor belt 21 is raised, the feeding plate 22 lifts the cable protection pipes. The cable protection tube is scooped up from the bottom of the soaking tank 11 and lifted upwards. During this process, the cable protection tube rolls down from the loading plate 22 onto the surface of the conveyor belt 21 under its own gravity. It is located within the angle formed by the loading plate 22 and the conveyor belt 21. It continues to be lifted by the conveyor belt 21 to the end of the conveyor belt 21. Finally, it falls into the clamping range of the electric gripper 32, which has been adjusted to a certain height, by the inertia of the conveyor belt 21 and its own gravity. The electric gripper 32 clamps the cable protection tube. Then, the liquid pump is started to pump the cleaning liquid into the spray head 18 to spray the cable protection tube on the electric gripper 32 to remove impurities from the outer surface of the cable protection tube.

[0025] Specifically, such as Figure 1 and Figure 4 As shown, the surface cleaning mechanism includes a climbing component 4, a cleaning component 5, a camera 6, a support component 7, a drive component 8, and two sets of connecting shafts 9. The climbing component 4, the support component 7, and the drive component 8 are connected sequentially via the connecting shafts 9. The cleaning component 5 is mounted on the climbing component 4, and the camera 6 is fixed on the cleaning component 5. The climbing component 4 is used to climb inside the cable protection pipe, the cleaning component 5 is used to clean the inner wall of the cable protection pipe, and the camera 6 is used to monitor the inner wall of the cable protection pipe, including but not limited to the observation of cleaning quality and inner wall quality. The support component 7 is used to provide support, and the drive component 8 is used to drive the climbing component 4 and the support component 7.

[0026] Furthermore, such as Figure 4 and Figure 6As shown, the climbing component 4 includes a bracket 41, which is configured as a triangular structure. Cylinders 42 are fixedly connected to the three sides of the bracket 41 respectively. A support plate 43 is fixedly connected to the output end of the cylinders 42. Tilting rollers 44 are rotatably connected to both ends of the support plate 43.

[0027] Furthermore, such as Figures 6-10 As shown, the cleaning assembly 5 includes a drive unit 51, a support cylinder 52, several nozzles 54, a brushing unit 57, and a water washing unit 58. A fixing groove is provided at the center of the bracket 41, and the drive unit 51 is fixed in the fixing groove. The support cylinder 52 is fixed at the end of the bracket 41 away from the support assembly 7. An air passage 53 and two sets of water passages 55 are provided inside the support cylinder 52. Two sets of water inlet pipes 56 are fixedly connected to the side of the support cylinder 52. The water inlet pipes 56 correspond to the positions of the water passages 55 and are connected to the water passages 55. The water inlet pipes 56 are connected to a pump body, which is placed in a cleaning liquid tank containing cleaning liquid. The pump body is used to pump the cleaning liquid in the cleaning liquid tank into the water passages 55. Several nozzles 54 are fixed at equal intervals on the side wall of the support cylinder 52. The nozzles 54 correspond to the positions of the air passage 53 and are connected to the air passage 53. An air pump is connected to the air passage 53 and is used to input gas to the nozzles 54 through the air passage 53.

[0028] Furthermore, such as Figures 6-8 As shown, the water washing unit 58 includes a jet flange 582 and several nozzles 583. A bracket 3 581 is fixedly connected to the end of the support cylinder 52 away from the drive unit 51. The jet flange 582 is fixed on the side of the bracket 3 581 away from the support cylinder 52. Several nozzles 583 are equidistantly arranged on the jet flange 582 along the axial direction of the jet flange 582. The end of the water passage 55 away from the water inlet pipe 56 is connected to the nozzles 583 through a pipe. The pipe connecting the water passage 55 and the nozzles 583 passes through the bracket 3 581. When the pump is started, the cleaning liquid in the cleaning liquid tank can be pumped into the water passage 55, and then pumped into the jet flange 582 through the connecting pipe, and sprayed out by the nozzles 583 to clean the inner wall of the cable protection pipe.

[0029] Furthermore, such as Figures 6-8 As shown, the brushing unit 57 includes a second bracket 571 and three sets of second cylinders 572. The second bracket 571 is hollow in the middle and is located between the support cylinder 52 and the third bracket 581. The two ends of the second bracket 571 are rotatably connected to the support cylinder 52 and the third bracket 581, respectively. The connection between the third bracket 581 and the support cylinder 52 is located inside the hollow part of the second bracket 571. The output end of the first drive unit 51 passes through the support cylinder 52 and is connected to the second bracket 571 through a gear set. The first drive unit 51 is used to drive the second bracket 571 to rotate through the gear set. like Figure 6 , Figure 9and Figure 10 As shown, three sets of cylinders 572 are equidistantly fixed on bracket 571 along the axis of support cylinder 52. A support base 573 is fixedly connected to the output end of each cylinder 572. A limit groove 574 is provided on the side of the support base 573 away from cylinders 572. Three pressure sensors 575, several springs 576, and a movable block 577 are installed inside the limit groove 574. The three pressure sensors 575 are respectively located at the bottom of the limit groove 574 and on both sides along the rotation direction of bracket 571. One side of each pressure sensor 575 is fixedly connected to the support base 573. The other side of the sensor 575 is fixedly connected to several springs 576, and the other end of the several springs 576 is fixedly connected to the movable block 577. The movable block 577 has a ramp around its perimeter near the limiting groove 574. A cleaning block 578 is fixedly connected to the side of the movable block 577 away from the support base 573. The cylinder 572 extends and retracts to adjust the distance between the cleaning block 578 and the inner wall of the cable protection pipe. The cleaning block 578 is used to clean the inner wall of the cable protection pipe. The pressure sensor 575 is used to detect the pressure change when the cleaning block 578 cleans the inner wall of the cable protection pipe.

[0030] like Figure 6 As shown, the camera 6 is fixed at the end of the nozzle 583 away from the bracket 581. The camera 6 is connected to the surface treatment module, which is also connected to the pressure sensor 575. The surface treatment module is used to acquire the image captured by the camera 6, determine the cleaning quality of the inner wall of the cable protection pipe, and acquire the pressure change when the cleaning block 578 cleans the inner wall of the cable protection pipe. In this way, the cleaning pressure and cleaning mode are adjusted to ensure that the inner wall of the cable protection pipe is cleaned evenly and thoroughly, thereby improving the cleaning quality.

[0031] In actual operation, the operator uses a robotic arm to place the surface treatment mechanism at the opening of the cable protection pipe held by the electric gripper 32. The climbing component 4 then enters the pipe to begin operation. At this time, the pump body starts, pumping the cleaning fluid in the cleaning fluid tank into the water circuit 55, and then into the jet flange 582 and nozzle 583 through the connecting pipeline. The nozzle 583 then washes and cleans the inner wall of the cable protection pipe with water, removing impurities attached to the inner wall. The cylinder 572 extends, causing the cleaning block 578 to fit against the inside of the cable protection pipe until the pressure sensor 575 at the bottom of the limit groove 574 can detect pressure data and ensure that the pressure data is within a certain pressure range. This pressure range is determined by the operator. After setting, the drive unit 51 is started, and the brushing unit 57 is rotated through the gear set. The cleaning block 578 brushes the inside of the cable protection tube to remove the inner wall deposits that are difficult to rinse off during water washing. At the same time, even if the cleaning fluid enters the limiting groove 574, the cleaning fluid can flow out along the inclined movable block 577 under the action of centrifugal force, avoiding the accumulation of liquid in the limiting groove 574 and reducing the service life of the pressure sensor 575. The air pump is started, and air is input into the nozzle 54 through the air passage 53. The airflow blows away the cleaning fluid in the cable protection tube, and at the same time, it can improve the drying efficiency of the inner wall of the cable protection tube by promoting the air flow.

[0032] Furthermore, such as Figure 5 As shown, the drive assembly 8 includes a second drive section 81. The output end of the second drive section 81 is connected to the corresponding connecting shaft 9. A fourth bracket 82 is sleeved on the outside of the second drive section 81. Three sets of third cylinders 83 are fixedly connected to the outside of the fourth bracket 82. An arc-shaped support plate 84 is fixedly connected to the output end of the third cylinder 83. Support rollers 85 are installed at both ends of the arc-shaped support plate 84.

[0033] Furthermore, such as Figure 5 As shown, the support component 7 and the drive component 8 have the same structural configuration. The difference is that the support component 7 is not driven by the drive unit 81, but is driven as a whole by the drive component 8.

[0034] In actual operation, the surface treatment device adopts a spiral propulsion structure. The axial rotation of the main drive motor, i.e., drive unit 81, is transmitted to the spiral wheel tilting roller 44 via the transmission conversion mechanism support assembly 7 and connecting shaft 9, causing the spiral wheel to form a spiral motion trajectory on the inner wall of the pipe, similar to a bolt rotating and advancing in a nut, thereby driving the device to move axially along the cable protection pipe.

[0035] It should be noted that when the connecting shaft 9 is a rigid shaft, the surface treatment device can be used for cleaning the inner wall of a straight pipe, and when the connecting shaft 9 is a flexible shaft, the surface treatment device can be used for cleaning the inner wall of a bent pipe, thereby improving the flexibility of the surface treatment device. The drive unit 2 81 can drive the surface treatment mechanism to move back and forth along the axial direction of the cable protection pipe inside the cable protection pipe.

[0036] Instructions for use of intelligent cable protection pipe surface treatment device: Step 1: Pipe soaking and ultrasonic cleaning: Adjust the height and angle of the limiting baffle 24 according to the size of the cable protection pipe, put the pipe into the soaking tank 11, turn on the ultrasonic transducer 15, soak and ultrasonically clean the pipe to remove most of the oil and impurities on the surface.

[0037] Step 2: Pipe feeding and external wall spraying: After soaking, the conveyor belt 21 is turned on, and the feeding plate 22 moves with the conveyor belt 21 to the bottom of the soaking tank 11, extends between the stacked cable protection pipes and scoops them up; the cable protection pipes are lifted to the end of the conveyor belt 21 and fall into the clamping range of the electric gripper 32 with the height adjusted by inertia and gravity. After the electric gripper 32 clamps the pipe, the liquid pump is started and the cleaning liquid is pumped into the spray head 18 to spray and clean the outer wall of the pipe to remove impurities from the outer surface.

[0038] Step 3: Positioning of the inner wall cleaning device: After the outer wall is sprayed, the robotic arm is used to place the surface treatment mechanism at the opening of the cable protection pipe held by the electric gripper 32, and the climbing component 4 then enters the pipe to start the operation.

[0039] Step 4: Inner Wall Cleaning and Quality Inspection: Drive unit 2 81 transmits rotational motion to tilting roller 44 via connecting shaft 9, causing the roller to form a spiral motion trajectory on the inner wall of the cable protection pipe, thereby driving the entire device to move axially along the cable protection pipe. At the same time, the pump body starts, pumping the cleaning fluid in the cleaning fluid tank into the water channel 55 and the jet flange 582 in sequence, and finally spraying it out from the nozzle 583 to perform high-pressure water washing on the inner wall of the cable protection pipe, removing loose impurities attached to the inner wall, and realizing continuous cleaning operation along the entire pipe length. During the movement, the camera 6 fixed at the front end of the nozzle 583 collects images of the inner wall of the pipe in real time and transmits the images to the surface treatment module. The surface treatment module analyzes the images, automatically identifies the type and degree of stains on the inner wall, determines the cleaning difficulty level of the current area, and dynamically matches the best cleaning mode combination when the surface treatment mechanism exits the cable protection pipe.

[0040] Specifically, in the light contamination mode (separate water wash): when only floating dust or slight stains are detected on the inner wall, the pump starts and pumps the cleaning fluid into the water path 55 and the jet flange 582. The high-pressure water jet is then sprayed out by the nozzle 583 to flush and quickly remove loose impurities, maintaining efficient operation.

[0041] Medium contamination mode (water washing + brushing synergy): When oxide scale or stubborn spots are detected, while water washing continues, cylinder 2 572 extends, pushing the cleaning block 578 to adhere to the pipe wall. Pressure sensor 575 monitors the contact pressure in real time to ensure that the cleaning block 578 is in constant contact with the pipe wall. Drive unit 1 51 starts and drives the brushing unit 57 to rotate through the gear set for wet brushing. The water flow plays a role in lubrication, cooling and chip removal in this process, improving brushing efficiency and reducing wear on the cleaning block 578.

[0042] Heavy pollution mode (water washing + brushing + air spray full linkage): When welding slag, solidified oil film and other extremely difficult-to-remove deposits are detected, the device starts the full linkage mode; nozzle 583 continuously sprays water to wet and soften stubborn stains; cleaning block 578, under the precise control of pressure sensor 575, adheres to the pipe wall and rotates powerfully to brush and mechanically peel off the deposits; at the same time, air pump starts, inputting high-speed airflow to nozzle 54 through air passage 53, quickly blowing the turbid liquid and debris generated by brushing out of the pipe to prevent secondary deposition, and assisting in drying after brushing.

[0043] Step 5: Pressure Adaptation and Dynamic Adjustment: During the brushing process, the pressure sensor 575 continuously monitors the pressure of the cleaning block 578 on the pipe wall and feeds the data back to the surface treatment module in real time. The surface treatment module automatically adjusts the extension and retraction of the cylinder 572 according to the preset pressure threshold to ensure that the cleaning pressure is always within the optimal range. When the pressure sensors 575 on both sides of the limit groove 574 detect a sudden change in pressure value, it means that the cleaning block 578 has encountered a local protrusion or depression. The surface treatment module responds quickly and controls the cylinder 572 to extend and retract in time to avoid over-washing and damage to the pipe wall or leaving dead corners due to missed washing.

[0044] Step Six: Continuous Operation and Full-Process Quality Control: Driven by the screw propulsion mechanism, the device moves at a constant speed along the pipe axis. The above-mentioned detection, judgment, cleaning, and feedback processes are executed cyclically during the movement, achieving uninterrupted continuous cleaning operations along the entire pipe length. Camera 6 performs a secondary confirmation of the cleaned area. If the cleaning quality is found to be substandard, the surface treatment module instructs the device to perform local re-washing in that area until the set standard is met.

[0045] The above methods can be used to clean the inner wall of the cable protection pipe evenly and thoroughly, and monitor the cleaning effect in real time, thereby improving the cleaning quality.
