[0057] The specific steps for cleaning the inner wall of the cylinder are as follows:

[0058] Step 1: Assemble the inner wall wiping machine of the cylinder, the liquid supply unit 2 is connected to the water inlet 115 of the wiping host 1 through a pipeline, and the power supply unit 3 is connected to the power supply port of the wiping host 1 through a cable;

[0059] Before use, check the completeness and integrity of all parts, open the carrying case, check whether any components are missing and whether the appearance of each part is intact. Check the position of each switch in the electrical control box and return it to the preset position.

[0060] If the pipeline is long, connect the pull rope to the lifting ring 116.

[0061] Fill the storage tank with cleaning liquid as needed (use cleaning liquid to wipe when the inner wall of the parts is severely rusted or has steel nodules, aluminum, copper, or paint); pour the cleaning liquid mixed in proportion into the storage tank, and then place the water pump in the storage tank. During use, observe the wiping effect. If the wiping effect is not good, continue wiping and add cleaning liquid to prevent the water pump from drying out. The cleaning agent can continue to be used after filtration and clarification to avoid blocking the liquid delivery pipeline and nozzle 117.

[0062] Test before use. After power on, test whether the control program is normal (manual / automatic), whether the crawler wheel 124, the second brush body 133, and the cleaning and polishing brush 13 are rotating, whether the wiping host 1 sprays liquid normally, and whether it works normally.

[0063] Step 2: Place the wiping main unit 1 into the pipeline, power the motor 112 of the wiping main unit 1, the motor 112 drives the reducer 113 to work, the reducer 113 drives the main shaft 122 to rotate, and the main shaft 122 drives the crawling wheel 124, the first brush body 128, and the cleaning and polishing brush 13 to rotate;

[0064] Turn the automatic / manual switch to the manual position, push the travel switch to the forward gear, then the green indicator light above the forward gear lights up, wait until the equipment body is completely inside the pipeline, turn on the spray switch on the control panel, then the green indicator light above the spray switch lights up, and the equipment starts to clean the inner wall of the pipeline.

[0065] The main shaft 122 drives the worm section 123 to rotate. By virtue of the meshing between the worm section 123 and the turbine 125 , the worm section 123 drives the turbine 125 to rotate, and the turbine 125 drives the creeper wheel 124 to rotate.

[0066] The main shaft 122 drives the bevel gear segment 126 to rotate, the annular gear plates on both sides of the bevel gear segment 126 drive the bevel gear 129 to rotate, and the bevel gear 129 drives the first brush body 128 to rotate.

[0067] The main shaft 122 drives the cleaning and polishing brush 13 to rotate, and the second brush body 133 outside the cleaning and polishing brush 13 rotates.

[0068] Step 3: The crawling wheel 124 drives the wiping main machine 1 to move forward in the pipeline, and the first brush body 128 and the cleaning and polishing brush 13 clean the inner wall of the pipeline.

[0069] When the wiping host 1 moves to the area where the inner diameter of the pipeline changes, the wiping host 1 stops moving forward, pushes the forward switch to the reverse gear, the green indicator light below the reverse gear lights up, the wiping host 1 moves backward and cleans the inner wall of the pipeline until the wiping host 1 protrudes out of the pipeline, and repeats the above operation if necessary.

[0070] If liquid spray cleaning is required, operate the liquid spray button of the electrical control box (green light turns on, green light turns off). After the water pump starts working, the cleaning liquid is injected into the water inlet 115 of the wiping host 1 through the pipeline. The cleaning liquid enters the casing 111 and is sprayed onto the inner wall of the pipe through the nozzle 117. The inner wall of the pipe is cleaned during the cleaning process.

[0071] The equipment should spray liquid for one minute and then spray again after an interval of five minutes. During wiping, pay attention to whether the cleaning liquid is used up. If the cleaning liquid is used up, push the spray switch on the electrical control box to the off position in time to turn off the spray function. At this time, the spray switch indicator light goes out, and move the manual forward button to the manual reverse position. At this time, the green indicator light below is on, so that the wiping host 1 exits and add cleaning liquid to the liquid storage barrel.

[0072] The terms used in the present invention are illustrative and exemplary, rather than restrictive. Since the present invention can be implemented 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 aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
