[0028] The defect marking device 2 includes an upper warehouse 21 installed at the upper end of the casing of the drone body 1, a pigment warehouse 22 is installed inside the upper warehouse 21, a high-pressure pump 23 is installed in the concave cavity of the pigment warehouse 22, and the feed end of the high-pressure pump 23 is located inside the pigment warehouse 22, and a nozzle 26 is provided at the discharge end of the high-pressure pump 23, and a nozzle 28 is installed at the discharge end of the nozzle 26. When a suspected defect is found, the high-pressure pump 23 sucks the pigment from the inside of the pigment warehouse 22, enters the nozzle 26 through the metal hose 24, and is finally sprayed out through the nozzle 28. The high-pressure sprayed pigment is directly sprayed onto the exterior wall surface, leaving a mark, and leaving a pigment mark around the defect, thereby realizing the positioning of the exterior wall defect, and then facilitating the later search and repair of the defect point.

[0029] A circular hole 27 is formed through the front side of the upper chamber 21 , and a nozzle 28 is located inside the circular hole 27 .

[0030] An extension body 25 is installed inside the upper bin 21, and a nozzle 26 is fixed on the movable end of the extension body 25. The extension body 25 includes a linear motor B251, which is installed inside the upper bin 21. The movable end of the linear motor B251 is fixedly connected with a linkage plate 255, and the nozzle 26 is inserted and installed on the linkage plate 255. A metal hose 24 is installed between the discharge end of the high-pressure pump 23 and the feed end of the nozzle 26. Before spray positioning, the linear motor B251 drives the linkage plate 255 to move toward the direction of the circular hole 27, and the linkage plate 255 moves the discharge end of the nozzle 26 toward the wall, thereby shortening the distance between the nozzle 28 and the wall, thereby ensuring that the paint adheres to the outer wall.

[0031] Slides 252 are installed inside the upper warehouse 21 and on both sides of the linear motor B251. A dovetail slide groove B254 is provided on the upper surface of the slide 252, and a dovetail guide block B253 is slidably provided inside the dovetail slide groove B254. The top of the dovetail guide block B253 is connected to the bottom end of the linkage plate 255. The extended body 25 is between the linkage plate 255 and the circular hole 27, and plays a supporting role for the nozzle 26, so that the downward force of the nozzle 26 is distributed more evenly, thereby improving the stability of the device and increasing its service life.

[0032] During use, the paint is filled into the paint bin 22, the drone body 1 is controlled to take off, and the camera 39 is used to shoot the outer wall, capture the outer circle, and detect defects on the outer wall;

[0033] When a defect is found, the high-pressure pump 23 sprays the paint from the paint bin 22, and the paint enters the spray pipe 26 through the metal hose 24, and finally sprays out through the spray head 28. The high-pressure sprayed paint is directly sprayed onto the exterior wall surface, leaving a mark.

[0034] After use, the nozzle 26 can be controlled to retract to prevent the nozzle 26 from protruding and affecting the storage of the device. Example
