[0039] Working principle: When in use, connect to an external power supply. First, the construction workers move the device to the designated construction site. The construction workers fix the slide rail 1 to the wall or fixed building of the designated construction site through multiple sets of fixing screws to facilitate subsequent dust suppression treatment.

When dust suppression operation is required, the water pump 13 transports the water inside the water tank 9 into the interior of the hose 14, and the hose 14 transports it to the interior of the liquid outlet cylinder 10 through the adapter sleeve 11. The water inside the liquid outlet cylinder 10 is sprayed to the external construction site through the nozzle 15 to play a role in dust suppression. When mobile spraying is required, the stepping motor 16 drives the main wheel 17 to rotate, and the main wheel 17 slides on the surface of the slide rail 1. At the same time, under the sliding support of multiple sets of support wheels 18, the walking frame 2 slides on the surface of the slide rail 1 to facilitate lateral mobile spraying.
