[0049] The method for using the traveling cleaning brush head for pipeline is as follows:

[0050] Step 1: Assemble the traveling main machine for cylinder inner wall cleaning machine.

[0051] If cleaning liquid is needed for the traveling main machine for cylinder inner wall cleaning machine, the liquid supply unit is connected to the water inlet 15 of the traveling main machine for cylinder inner wall cleaning machine through a pipeline, and the power supply unit is connected to the power supply port of the traveling main machine for cylinder inner wall cleaning machine through a cable.

[0052] Before use, check the completeness and integrity of each part, open the carrying case, check whether each component is missing, and whether the appearance of each part is intact. Check the position of each switch of the electrical control box, and return to the preset position.

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

[0054] According to the situation, fill the cleaning liquid into the liquid storage barrel (use the cleaning liquid for wiping when the inner wall of the part is severely rusted or has steel tumors, aluminum, copper, and paint); pour the cleaning liquid mixed in proportion into the liquid storage barrel, and then place the water pump in the liquid storage barrel. During use, observe the wiping effect. If the wiping effect is not good, continue to wipe and add cleaning liquid to prevent the water pump from drying out. The cleaning agent can be used continuously after being filtered and clarified to prevent the liquid delivery pipeline and nozzle 17 from being blocked.

[0055] Before use, test whether the control program is normal (manual / automatic) after power-on, whether the crawling wheel 24, the second brush body 33, and the cleaning and polishing brush 3 rotate, whether the traveling main machine for cylinder inner wall cleaning machine normally sprays liquid, and whether the work is normal.

[0056] Step 2: Place the traveling main machine for cylinder inner wall cleaning machine into the pipeline, power the motor 12 of the traveling main machine for cylinder inner wall cleaning machine, drive the speed reducer 13 to work by the motor 12, drive the main shaft 22 to rotate by the speed reducer 13, and drive the crawling wheel 24, the first brush body 28, and the cleaning and polishing brush 3 to rotate by the main shaft 22.

[0057] Turn the automatic / manual switch to the manual position, and push the walking switch to the forward gear position. At this time, the green indicator light above the forward gear position is on. After the equipment body is completely placed into the pipeline, turn on the liquid spraying switch on the control panel. At this time, the green indicator light above the liquid spraying switch is on, and the equipment starts to clean the inner wall of the pipeline.

[0058] The main shaft 22 drives the worm segment 23 to rotate, the worm segment 23 drives the turbine 25 to rotate through the meshing of the worm segment 23 and the turbine 25, and the turbine 25 drives the crawling wheel 24 to rotate.

[0059] The main shaft 22 drives the bevel gear segment 26 to rotate, the annular toothed discs on both sides of the bevel gear segment 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 crawling wheel 24 drives the cylinder inner wall wiping machine to move forward in the pipeline, and the first brush body 28 and the cleaning and polishing brush 3 clean the inner wall of the pipeline.

[0062] When the cylinder inner wall wiping machine travels to a pipeline inner diameter change area, the cylinder inner wall wiping machine stops advancing, the forward switch is pushed to the backward gear position, the green indicator light under the backward gear position is on, the cylinder inner wall wiping machine retreats and cleans the inner wall of the pipeline, and the cylinder inner wall wiping machine is pulled out of the pipeline, and the above operation is repeated if necessary.

[0063] If liquid spraying cleaning is needed, the liquid spraying button of the electrical control box is operated (the green light is on and the green light is off), the water pump works, and the cleaning liquid is injected into the water inlet 15 of the cylinder inner wall wiping machine through the pipeline, the cleaning liquid enters the machine shell 11, and the cleaning liquid is sprayed to the inner wall of the pipeline through the nozzle 17, so that the inner wall of the pipeline is cleaned.

[0064] The equipment sprays liquid every five minutes after spraying liquid for one minute, and it is observed whether the cleaning liquid is used up during wiping, if the cleaning liquid is used up, the liquid spraying switch on the electrical control box is pushed to the closed gear position in time, the liquid spraying function is closed, the liquid spraying switch indicator light is turned off at this time, the manual forward button is moved to the manual backward position at this time, the lower green indicator light is on, the cylinder inner wall wiping machine is withdrawn, and the cleaning liquid is added to the liquid storage barrel.

[0065] The terms used in the utility model are illustrative and non-limiting terms. Since the utility model can be embodied in various forms without departing from the spirit or essence of the technical scheme, it should be understood that the above examples are not limited to any of the above details, but should be widely interpreted within the spirit and scope defined in the appended claims, and therefore all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
