[0045] A cleaning structure 5 is arranged on the surface of the camera 3, and the cleaning structure 5 includes a limit frame 502 fixedly connected to the surface of the camera 4, a slider 511 is slidably connected to the surface of the limit frame 502, a wind frame 509 is fixedly installed on the side wall of the slider 511, a folding tube 508 of a folding structure is fixedly connected to the upper surface of the wind frame 509, a pressing plate 507 is fixedly installed on the upper end of the folding tube 508, a fixing strip 510 is fixedly connected to the surface of the camera 4, a wavy strip 501 is fixedly installed on the end side of the fixing strip 510, and a convex strip 515 is fixedly connected to the side wall of the pressing plate 507;

[0046] The auxiliary structure 6 is arranged on the surface of the wind frame 509, and the auxiliary structure 6 includes a heat preservation frame 61 fixedly connected to the lower port of the wind frame 509. The heat preservation frame 61 is a hollow structure, and a plurality of air holes 66 are opened on the surface of the heat preservation frame 61. The inner walls of the two air holes 66 are fixedly connected with a plastic film 64 of a cylindrical structure.

[0047] The adjustment structure 7 is arranged on the surface of the insulation frame 61, and the adjustment structure 7 includes two positioning bars 75 fixedly connected to the surface of the insulation frame 61. The side walls of the two positioning bars 75 are slidably connected with a movable plate 71, and a plurality of adjustment holes 72 are evenly opened on the surface of the movable plate 71. By setting the cleaning structure 5, it is convenient to clean the camera 4 mirror surface by blowing, and the phenomenon that the camera 4 mirror surface is easily scratched by directly wiping and cleaning the dust, and the wind generated in the blowing process can also realize the rapid drying of the water mist on the surface of the drone lens when the drone is used in rainy weather, thereby further improving the clarity of the lens surface. By setting the auxiliary structure 6, it is convenient to quickly melt and dry the wind frost on the surface of the drone lens in some relatively cold weather conditions where frost is prone to appear, thereby further improving the performance of the drone and the applicable environment of the drone. By setting the adjustment structure 7, it is convenient to flexibly adjust the size of the blowing wind. When the adjusted air outlet is larger, a large area of ​​hot air can be passed through, and a large area of ​​frost on the lens surface can be melted. The smaller the adjusted air outlet is, the greater the wind force blown out. At this time, some tightly adhered dust can be cleaned, thereby improving the performance of the drone under different conditions.

[0048] The specific settings and functions of the cleaning structure 5, the auxiliary structure 6 and the regulating structure 7 are described in detail below.

[0049] like Figure 1-Figure 3 and Figure 7-Figure 9 As shown, the cross section of the wave strip 501 is a wave line structure. The convex strip 515 will be compressed by the wave strip 501 to shrink, and vice versa, the convex strip 515 will be stretched by the rebound effect of the folding tube 508. The cleaning structure 5 also includes two mounting rods 504 fixedly connected to the surface of the limit frame 502, and the ends of the two mounting rods 504 close to each other are fixedly connected with a mounting ring 506, and the inner side of the mounting ring 506 is fixedly installed with a servo motor 505, and the output end of the servo motor 505 is fixedly connected with a screw rod 503, and the screw rod 503 and the internal thread connection of the slider 511. Start the servo motor 505, the servo motor 505 will drive the screw rod 503 to rotate, so as to realize the driving work of the slider 511, and the slider 511 can realize the driving work of the wind frame 509 during the movement, and the wind frame 509 will drive the folding tube 508 and the pressure plate 507 to move at the same time. Two positioning blocks 512 are fixedly connected to the surface of the wind frame 509, and two mounting plates 514 are fixedly connected to the side wall of the pressure plate 507. A sliding pin 513 is slidably connected inside the mounting plate 514, and the lower end of the sliding pin 513 is fixedly connected to the positioning block 512. By setting the sliding pin 513 to slide inside the mounting plate 514, the compression direction of the folding tube 508 is limited.

[0050] like Figure 1-Figure 4 and Figure 6 As shown, the surface of the heat preservation frame 61 is connected with a water injection pipe 62. Hot water is injected into the inner side of the heat preservation frame 61 through the water injection pipe 62. A threaded plug 63 is threadedly connected to the inner side of the port of the water injection pipe 62. The threaded plug 63 is rotated to the inner side of the water injection pipe 62. A cover plate 65 is fixedly connected to the upper end of the threaded plug 63. The cover plate 65 covers the inner side of the pipe opening of the water injection pipe 62.

[0051] like Figure 1-Figure 6 As shown, the adjustment hole 72 and the air hole 66 are both diamond-shaped holes. Since the air hole 66 and the adjustment hole 72 are both diamond-shaped structures, the gap formed by the staggered gap between the two is still a diamond-shaped structure. The inner rotation of the heat preservation frame 61 is connected with a screw rod 73, and the screw rod 73 is connected with the inner thread of the movable plate 71. The screw rod 73 drives the movable plate 71 to slide on the side wall of the positioning bar 75 during the driving process. The other end of the screw rod 73 is fixedly connected with a rotating block 74. The rotating block 74 can realize the driving work of the screw rod 73.

[0052] Working principle: When using a drone for long-distance safety inspections of power transmission lines, when it is necessary to clean the surface of the camera 4, start the servo motor 505, and the servo motor 505 will drive the screw rod 503 to rotate, thereby realizing the driving work of the slider 511. The slider 511 can drive the wind frame 509 during the movement, and the wind frame 509 will drive the folding tube 508 and the pressure plate 507 to move at the same time. The convex strip 515 on the pressure plate 507 will move relative to the wavy strip 501 of the wavy line structure. When the convex strip 515 moves to the protruding position of the wavy strip 501, the convex strip 515 will be compressed by the wavy strip 501 and shrink. Conversely, the convex strip 515 will be stretched by the rebound effect of the folding tube 508. At this time, the stretching work of the wavy strip 501 can be realized. The reciprocating compression of the tube 508 and the gas generated during the compression of the folding tube 508 will blow away the dust and other particulate impurities on the surface of the camera 4, thereby realizing the cleaning of the surface of the camera 4 and improving the clarity of the camera 4 during use as much as possible. By setting the sliding pin 513 to slide inside the mounting plate 514, the compression direction of the folding tube 508 is limited, and the stability of the compression of the folding tube 508 is improved. By setting the cleaning structure 5, it is convenient to clean the mirror surface of the camera 4 by blowing, avoiding the phenomenon that the dust on the mirror surface of the camera 4 is directly wiped and cleaned, which is easy to scratch the lens. In addition, the wind generated during the blowing process can also realize the rapid drying of the water mist on the surface of the drone lens when the drone is used in rainy weather, thereby further improving the clarity of the lens surface.

[0053] When the drone is used in some cold weather conditions where frost is prone to occur, before using the drone, hot water is first injected into the inner side of the heat preservation frame 61 through the water injection pipe 62, and then the threaded plug 63 is rotated to the inner side of the water injection pipe 62, and the cover plate 65 will cover the inner side of the pipe mouth of the water injection pipe 62, so that the sealing work of the pipe mouth position of the water injection pipe 62 can be achieved. During the compression and blowing process, the blown gas will pass through the plastic film 64 of the tubular structure, thereby facilitating the heating of the blown gas, and then facilitating the rapid melting and drying of the frost on the surface of the lens, further improving the clarity of the lens shooting effect, by setting the heat preservation frame 61 with a heat preservation structure, the phenomenon of rapid heat consumption and loss is avoided, and the plastic film 64 has a poor heat insulation effect, and the heat here is convenient to discharge, thereby improving the utilization effect of the heat, and by setting the auxiliary structure 6, it is convenient to melt and dry the frost on the surface of the drone lens in some cold weather conditions where frost is prone to occur, thereby further improving the use performance of the drone and improving the applicable environment of the drone.

[0054] By rotating the rotating block 74, the screw 73 can be driven to rotate. During the driving process, the screw 73 will drive the movable plate 71 to slide on the side wall of the positioning bar 75. The sliding of the movable plate 71 on the surface of the positioning bar 75 plays a role in limiting the moving direction of the movable plate 71. At this time, the misalignment adjustment work between the adjustment hole 72 and the air hole 66 can be achieved. Since the air hole 66 and the adjustment hole 72 are both diamond-shaped structures, the gap formed by the misalignment between the two is still a diamond-shaped structure. By adjusting the moving distance of the movable plate 71, it is convenient to adjust the misalignment The pore size is adjusted, and the pores formed by staggering are the pores for blowing out air, which facilitates the adjustment of the size of the blowing air. By setting the adjustment structure 7, it is convenient to flexibly adjust the size of the blowing wind. When the adjusted air outlet is larger, a large area of ​​hot air can pass through, and a large area of ​​frost on the lens surface can be melted. The smaller the adjusted air outlet is, the greater the wind force is. At this time, some tightly adhered dust can be cleaned, thereby improving the performance of the drone under different conditions.
