[0045] The water scraping unit is tightly attached to the surface of the sound barrier through the scraping strip 28 on the scraping plate 27, and scrapes off the remaining water when the device moves.

[0046] The guide plate 15 guides the stains and waste water falling during the cleaning process.

[0047] Working process:

[0048] Start the device, move the device to the position of the sound barrier to be cleaned through the walking wheels 3 and the push handle 2.

[0049] Start the telescopic cylinder 1 9, drive the sliding plate 1 and the supporting plate 16 to move horizontally in the rectangular slot, and align the cleaning assembly with the initial cleaning position of the sound barrier.

[0050] Start the telescopic cylinder 2 36 to make the scraping plate 27 tightly attached to the sound barrier.

[0051] Start the telescopic cylinder 3 37 to make the cleaning roller 25 tightly attached to the sound barrier.

[0052] Start the rotating motor 1 9 to drive the transmission assembly to rotate, drive the lead screw 10 to rotate, and make the connecting plate 17 and the cleaning assembly move up and down along the height direction of the sound barrier.

[0053] Start the rinsing unit to spray the cleaning liquid onto the surface of the sound barrier through the water pump 30 to perform preliminary rinsing.

[0054] Start the cleaning unit to make the cleaning brush 6 on the two cleaning rollers 25 contact the surface of the sound barrier to clean the sound barrier. At the same time, start the rotating motor 2 35 to drive the two cleaning rollers 25 to move alternately and remove stubborn stains on the surface of the sound barrier.

[0055] After cleaning, start the water scraping unit to make the scraping strip 28 on the scraping plate 27 tightly attached to the surface of the sound barrier to scrape off the remaining water.

[0056] The stains and waste water falling during the cleaning process are guided through the guide plate 15.
