Abstract: The present invention relates to an atmospheric environment-improving drone having life-saving and advertising functions, and more specifically, to a drone configured to move while hovering in the air, the drone comprising: a drone body; and a hovering transport unit for hovering the drone body in the air and moving same. The drone body is provided with a water spray means for purifying the air by adsorbing dust and fine dust in the air. The water spray means includes: support shafts, each of which has one end fixed on the outer surface of the drone body; spray liquid supply pipes fixed to lower portions of the support shafts; and spray liquid spraying nozzles formed at regular intervals on the purified liquid supply pipes. Since the drone configured to move while hovering in the air is used to spray water from the air, the drone can spray a wider area than ground-based water spray devices, thus having the effect of improving the purification efficiency for contaminants or fine dust in the air.

Abstract: The present invention relates to a drone for painting an outer wall of a multi-story building and, more specifically, to a painting drone which can float and move in the air and comprises a drone body and a floating and moving part for floating and moving the drone body in the air. A camera unit for obtaining an image of the outer surface of a building is provided on the drone body. Driving wheels for guidance to the outer surface of the building are provided on one surface of the drone body. Absorption angle members are further formed on the drone body in order to absorb the impact from the building. Paint nozzle parts for painting by spraying paint on the outer surface of the building are further formed on the drone body. By using a drone which can float and move in the air to paint an outer wall of a skyscraper, cost or painting the sky scraper can be reduced, the painting work can be simplified, fatal accidents due to falls can be prevented, and painting time can be shortened.

Abstract: A drone for cleaning an outer wall of a high-rise building is configured to float and move in the air. The drone includes a drone main body and a floating transfer unit for floating and moving the drone main body in the art. The drone main body has a camera unit provided to photograph the exterior of a building and driving wheels on one surface thereof to be guide to the exterior of the building. The drone main body further has a buffer angle member to cushion an impact with the building and a washing nozzle unit which sprays water onto and washes the exterior of the building. Accordingly, by cleaning the exterior or a window of a skyscraper using the drone, there are the effects of reducing the costs of cleaning a skyscraper, simplifying a cleaning operation, preventing human accidents due to falls, and reducing cleaning time.
