[0034] Embodiment: the existing coating storage is prone to segregation phenomenon, and the color is relatively light when marking, which affects use, so the embodiment is through the following technical scheme, such as Figure 1 、 Figure 3 And Figure 6 Since stirring assembly 5 includes first connecting shaft 501, stirring motor 502 and stirring blade 503, the outer surface of first connecting shaft 501 is embeddedly connected with stirring blade 503 at equal intervals, and stirring blade 503 constitutes a rotating structure in the inside of liquid storage cavity 4 through first connecting shaft 501;

[0035] Therefore, the inside of liquid storage cavity 4 stores coating, wing 3 works to make unmanned aerial vehicle main body 1 fly up to pipeline inspection through installation arm 2, and first connecting shaft 501 rotates in the inside of liquid storage cavity 4 when stirring motor 502 works;

[0036] When the first connecting shaft 501 rotates, the equidistantly arranged stirring blades 503 rotate in the interior of the liquid storage cavity 4, so that the equidistantly arranged stirring blades 503 stir the paint in the liquid storage cavity 4 in rotation, prevent the paint in the liquid storage cavity 4 from segregating, affect the quality during marking, and thus prevent the paint from precipitating;

[0037] The existing unmanned aerial vehicle causes air disturbance in the flight inspection process, various sensors are close to the propeller of the unmanned aerial vehicle, and the detection accuracy of the sensors is reduced due to the air disturbance during detection. Therefore, the embodiment achieves the following technical solutions, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The front end of the first bevel gear 13 is connected with the second bevel gear 14, the second connecting shaft 15, the second bevel gear 14, the first bevel gear 13 and the threaded rod 12 form a linkage structure, and the mounting seat 11 forms a lifting structure on the lower side of the unmanned aerial vehicle body 1 through the threaded rod 12 and the support rod 10;
