[0049] The specific steps for wiping the inner wall of the cylinder to clean the main unit are as follows:

[0050] Step 1: Wipe the inner wall of the cylinder and wipe the traveling main unit;

[0051] If cleaning fluid needs to be supplied to the inner wall of the cylinder for wiping the traveling unit, the fluid supply unit is connected to the water inlet 15 of the inner wall wiping traveling unit through a pipeline, and the power supply unit is connected to the power supply port of the inner wall wiping traveling unit through a cable.

[0052] Before use, check the completeness and integrity of all components. Open the carrying case and check for any missing parts and the appearance of each part. Check the positions of all switches in the electrical control box and return them to their preset positions.

[0053] If the pipeline is long, connect the pull rope to the lifting ring 16.

[0054] Add cleaning fluid to the storage tank as needed (use cleaning fluid to wipe parts with severe internal corrosion, steel nodules, aluminum residue, copper residue, or paint residue); pour the diluted cleaning fluid into the storage tank, then place the water pump inside. Observe the wiping effect during use. If the wiping effect is not good, continue wiping and add more cleaning fluid to prevent the water pump from running dry. The cleaning agent can be reused after filtration and clarification to avoid clogging the liquid delivery pipes and nozzles.

[0055] Before use, test whether the control program is normal (manual / automatic) after powering on, whether the crawler wheel 24, the second brush body 33, and the cleaning and polishing brush 3 are rotating, whether the inner wall of the cylinder is properly sprayed with liquid for wiping the traveling host, and whether the operation is normal.

[0056] Step 2: Place the inner wall wiping and moving main unit into the pipe, and power the motor 12 of the inner wall wiping and moving main unit. The motor 12 drives the reducer 13 to work, the reducer 13 drives the main shaft 22 to rotate, and the main shaft 22 drives the crawling wheel 24, the first brush body 28, and the cleaning and polishing brush 3 to rotate.

[0057] Switch the automatic / manual switch to the manual position and push the travel switch to the forward position. At this time, the green indicator light above the forward position will light up. After the entire equipment body is inside the pipeline, turn on the spray switch on the control panel. At this time, the green indicator light above the spray switch will light up, and the equipment will begin cleaning the inner wall of the pipeline.

[0058] The main shaft 22 drives the worm gear section 23 to rotate. By engaging the worm gear section 23 with the turbine 25, the worm gear section 23 drives the turbine 25 to rotate, and the turbine 25 drives the crawler wheel 24 to rotate.

[0059] The main shaft 22 drives the bevel gear section 26 to rotate, and the annular gear discs on both sides of the bevel gear section 26 drive the bevel gear 29 to rotate, and the bevel gear 29 drives the first brush body 28 to rotate.

[0060] The main shaft 22 drives the cleaning and polishing brush 3 to rotate, and the second brush body 33 on the outer side of the cleaning and polishing brush 3 rotates.

[0061] Step 3: The crawler wheel 24 drives the inner wall of the cylinder to move forward in the pipe, and the first brush body 28 and the cleaning and polishing brush 3 clean the inner wall of the pipe.

[0062] When the inner wall wiping moving unit moves to the area where the inner diameter of the pipe changes, the inner wall wiping moving unit stops moving forward. Push the forward switch to the reverse position. The green indicator light below the reverse position will light up. The inner wall wiping moving unit will move backward and clean the inner wall of the pipe until the inner wall wiping moving unit protrudes out of the pipe. Repeat the above operation if necessary.

[0063] If liquid cleaning is required, operate the liquid spray button on the electrical control box (green light on, green light off). After the water pump starts working, the cleaning fluid is injected into the water inlet 15 of the moving main unit through the pipeline. The cleaning fluid enters the casing 11 and is sprayed onto the inner wall of the pipeline through the nozzle 17, cleaning the inner wall of the pipeline during the cleaning process.

[0064] After spraying the liquid for one minute, wait five minutes before spraying again. During the wiping process, carefully observe whether the cleaning liquid is used up. If the cleaning liquid is used up, promptly push the spray switch on the electrical control box to the off position to turn off the spraying function. At this time, the spray switch indicator light will turn off. Move the manual forward button to the manual reverse position. At this time, the green indicator light below will light up, causing the wiping and moving main unit inside the cylinder to retract. Add cleaning liquid to the storage tank.

[0065] The terminology used in this invention is descriptive and exemplary, and not restrictive. Since this invention can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
