[0002] An unmanned aerial vehicle (UAV), also known as a drone, is an unmanned aircraft that flies remotely and / or autonomously. A drone does not require a pilot to operate it; the entire flight process is automatically controlled by electronic equipment. Drones do not require any pilot-related equipment, freeing up space and weight for more important equipment. Based on their application areas, drones can be categorized as military, civilian, and consumer. Civilian drones are widely used in aerial filming, traditional agriculture and forestry, industrial operations, disaster relief, public safety, and consumer entertainment.

[0003] High-altitude cleaning drones are mainly used to clean building exterior walls, bridges, cooling towers, etc. Since the holes of the drone's spray head are fixed, when the drone is operating at high altitude, the sprayed cleaning liquid can easily concentrate together, making it impossible to carry out large-scale cleaning.

[0017] Preferably, one end of the elastic strip away from the sliding plate is fixedly connected to a bottom connecting rod, and the bottom of the fixed block is fixedly connected to a limiting plate;

[0018] The limiting plate is used for limiting the bottom connecting rod.

DETAILED DESCRIPTION

[0041] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 11 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, it includes a drive component 1 for performing power control processing on the entire drone;

[0043] A lifting mechanism 2 for lifting the entire drone, the lifting mechanism 2 being arranged outside the driving assembly 1;

[0044] The spraying mechanism 3 is used for spraying materials at high altitude, and the spraying mechanism 3 is arranged at the bottom of the driving component 1.

[0045] The lifting mechanism 2 includes a connecting rod 21, which is installed on the outside of the driving assembly 1. An adjustment assembly 22 is provided on the outside of the connecting rod 21. A control console 23 is installed on the end of the connecting rod 21 away from the driving assembly 1. A spiral blade 24 is installed on the top of the control console 23 through a shaft. The spiral blade 24 is used to control the lifting of the drone.

[0046] A rotating shaft 25 is provided at the bottom of the console 23. The top end of the rotating shaft 25 is fixedly connected to the shaft body. A No. 1 bearing 26 is squeezed and fitted on the bottom of the rotating shaft 25. A circular seat 27 is fixedly connected to the outer side of the No. 1 bearing 26. A No. 1 rail groove 28 is defined inside the circular seat 27. A No. 1 reset folding piece 29 is slidably fitted inside the No. 1 rail groove 28.

[0047] The outer side of the rotating shaft 25 is extruded and adapted with the No. 2 bearing 20, and the outer side of the No. 2 bearing 20 is fixedly connected with a circular disk 201, the interior of the circular disk 201 is provided with a No. 2 rail groove 208, and the interior of the No. 2 rail groove 208 is slidably adapted with a No. 2 reset folding piece 202; in addition, the arc seat 203 is fixedly connected to the rotating shaft 25, so the No. 2 reset folding piece 202 and the No. 1 reset folding piece 29 will rotate in the No. 2 rail groove 208 and the No. 1 rail groove 28 respectively, and the part of the folding piece that slides with the rail groove is rigid, while the rest of the part can be folded and retracted.

[0048] An arc-shaped seat 203 is fixedly installed on the outer side of the rotating shaft 25, and a telescopic plate 204 is rotatably installed inside the arc-shaped seat 203. The end of the telescopic plate 204 away from the arc-shaped seat 203 is fixedly connected to a double-headed ring plate 205, and the upper and lower ends of the double-headed ring plate 205 are respectively fixedly connected to the No. 2 reset folding piece 202 and the No. 1 reset folding piece 29; start the drive component 1 to make the spiral blade 24 rotate, wherein the connecting rod 21 and the adjustment component 22 are used to protect and stabilize the power component, and then the rotation of the four spiral blades 24 will drive the entire drone to take off. When the drone needs to rise again and spray at high altitude, the speed of the spiral blade 24 will increase, and the shaft at the center of the spiral blade 24 is connected to the rotating shaft 25, so the rotating shaft 25 will rotate accordingly. Under the action of centrifugal force, the telescopic plate 204, which was originally in a downward tilted state, will tend to deflect upward. Subsequently, the telescopic plate 204 will deflect upward with the arc seat 203 as the fulcrum, and the double-headed ring plate 205 connected to the other end of the telescopic plate 204 will deflect upward accordingly. However, the upper and lower ends of the double-headed ring plate 205 are respectively connected to the No. 2 reset folding piece 202 and the No. 1 reset folding piece. The stack 29 is fixedly connected, so the No. 2 reset folding sheet 202 will shrink into the circular disk 201, and the No. 1 reset folding sheet 29 will extend outward from the circular seat 27. The No. 2 reset folding sheet 202 and the No. 1 reset folding sheet 29 are foldable, and the rigidity of their extended state is much greater than the outward squeezing force generated by the upward deflection of the telescopic plate 204. Therefore, the deflection force load passing through the telescopic plate 204 is less than the bearing load of the folding sheet itself, and does not reach the yield strength of the folding sheet, thereby causing the No. 2 reset folding sheet 202 and the No. 1 reset folding sheet 29 to stretch and shrink in an inclined state.

[0049] An extension rod 206 is fixedly connected to the outer side of the double-headed ring plate 205 , and an outer connecting ring 207 is fixedly connected to one end of the extension rod 206 away from the double-headed ring plate 205 .

[0050] The adjustment assembly 22 includes a fixed block 221, which is fixedly mounted on the outside of the connecting rod 21. A U-shaped groove 222 is formed inside the fixed block 221. An elastic strip 223 is slidably adapted inside the U-shaped groove 222. One end of the elastic strip 223 is fixedly connected to a sliding plate 224, which is slidably adapted on the outside of the fixed block 221.

[0051] The bottom of the sliding plate 224 is fixedly connected to a return spring 225 , the bottom end of the return spring 225 is fixedly connected to the fixed block 221 , and the outer side of the sliding plate 224 is squeezed and adapted to the outer ring 207 ;

[0052] The outer ring 207 is used to adjust the height of the sliding plate 224;

[0053] One end of the elastic strip 223 away from the sliding plate 224 is fixedly connected to the bottom connecting rod 226, and the bottom of the fixed block 221 is fixedly connected to the limiting plate 227;

[0054] The limiting plate 227 is used to limit the bottom connecting rod 226. As the double-headed ring plate 205 rotates and moves obliquely upward, the extension rod 206 fixedly connected to its outer side will move obliquely upward with the outer connecting ring 207, wherein the outer connecting ring 207 is elastic, and in the process of the outer connecting ring 207 moving obliquely upward and expanding, it will squeeze the sliding plate 224, and the squeezed sliding plate 224 will move upward along the U-shaped groove 222 provided in the fixed block 221, and stretch the return spring 225, wherein the return spring 225 plays a role in resetting the sliding plate 224, and the upward movement of the sliding plate 224 will squeeze the elastic strip 223, wherein the elastic strip 223 is elastic, and its other end is connected to the bottom connecting rod 226, so the bottom connecting rod 226 will Move downward along the limit plate 227. In addition, the bottom of the bottom connecting rod 226 is connected to the circular ring 301, so the circular ring 301 will move downward with the multi-disc ring 30, and the bottom of the multi-disc ring 30 is connected to the top rod 38. Therefore, the top rod 38 will move downward with the blocking tube 35, so that the blocking tube 35 will extend outward from the bottom of the spray head 34. The blocking tube 35 initially blocks the holes in this part, so that the cleaning liquid can only be sprayed outward from the center of the spray head 34. As the blocking tube 35 extends downward, the cleaning liquid will also be sprayed outward from the outer holes, thereby increasing the spraying range of the cleaning liquid when the drone is operating at high altitude, and focusing more on large-scale cleaning operations.

[0055] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the spraying mechanism 3 includes a material receiving basket 31, which is mounted on the bottom of the driving assembly 1 through fasteners. The bottom of the driving assembly 1 is fixedly connected to a support frame 32. The outer side of the material receiving basket 31 is fixedly connected to a material delivery pipe 33. The end of the delivery pipe 33 away from the material receiving basket 31 is fixedly connected to a spray head 34. The material receiving basket 31 is used for receiving and processing the cleaning liquid. In addition, releasing the fasteners can separate the material receiving basket 31 from the driving assembly 1 to facilitate the replenishment and cleaning of the cleaning liquid. Then the delivery pipe 33 will transport the cleaning liquid inside the material receiving basket 31 to the spray head 34 for spraying.

[0056] A blocking tube 35 is inserted into the bottom of the spray head 34, sealing a row of openings at the bottom of the spray head 34. A perforation 36 is formed on the outside of the blocking tube 35, and a spring 37 is fixedly connected to the outside of the blocking tube 35. The bottom end of the spring 37 is fixedly connected to the bottom of the inner cavity of the spray head 34. The spring 37 resets the blocking tube 35, while the beveled plate 39 prevents the cleaning fluid from overflowing. The perforation 36 also allows the cleaning fluid inside the spray head 34 to be sprayed outward, thereby expanding the spray range.

[0057] The spring 37 is used to reset the blocking tube 35;

[0058] The top of the plugging tube 35 is fixedly connected to a push rod 38, and the outer side of the push rod 38 is sleeved with a bevel disk 39, which is fixedly connected to the outer side of the spray head 34. The top of the push rod 38 is fixedly installed with a multi-disc ring 30;

[0059] The top of the multi-disc ring 30 is fixedly connected to a circular ring 301 , the top of the circular ring 301 is fixedly connected to the bottom connecting rod 226 , and the bottom of the circular ring 301 is fixedly connected to a vertical rod 305 ;

[0060] A baffle 302 is fixedly connected to the outside of the support frame 32. A handle 303 is fixedly mounted at the bottom of the baffle 302. A plug-in board 304 is plugged into the bottom of the handle 303. The outside of the plug-in board 304 is fixedly connected to a vertical rod 305. As the ring 301 moves downward, the vertical rod 305 connected to its bottom moves downward, carrying the plug-in board 304 with it. The plug-in board 304 then extends downward from the handle 303. When the drone is at high altitude, the downward extension of the plug-in board 304 protects the sprayed cleaning fluid from being carried away by high-altitude airflow. Furthermore, the baffle 302 blocks and guides the airflow generated by the spiral blades 24 during rotation, preventing it from affecting the cleaning fluid.

[0061] On the contrary, when the drone is at low altitude, the cleaning fluid sprayed out will be concentrated together, thereby playing the role of centralized cleaning treatment of fixed points.

[0062] When the present invention is in use: first, the driving component 1 is started to rotate the spiral blades 24, wherein the connecting rod 21 and the adjustment component 22 are used to protect and stabilize the power components, and then the rotation of the four spiral blades 24 will drive the entire drone into the air. When the drone needs to rise again and perform high-altitude spraying, the rotation speed of the spiral blades 24 will accelerate, and the shaft at the center of the spiral blades 24 is connected to the rotating shaft 25, so the rotating shaft 25 will rotate accordingly. Under the action of centrifugal force, the telescopic plate 204, which was originally in a downward tilted state, will tend to deflect upward, and then the telescopic plate 204 will deflect upward with the arc seat 203 as the fulcrum, and the double-headed ring plate 205 connected to the other end of the telescopic plate 204 will It will deflect upward accordingly, however, the upper and lower ends of the double-headed ring plate 205 are fixedly connected to the No. 2 reset folding piece 202 and the No. 1 reset folding piece 29 respectively, so the No. 2 reset folding piece 202 will shrink into the circular disk 201, and the No. 1 reset folding piece 29 will extend outward from the circular seat 27. In addition, the arc seat 203 is fixedly connected to the rotating shaft 25, so the No. 2 reset folding piece 202 and the No. 1 reset folding piece 29 will rotate in the No. 2 rail groove 208 and the No. 1 rail groove 28 respectively.

[0063] As the double-headed ring plate 205 rotates and moves obliquely upward, the extension rod 206 fixedly connected to its outer side will move obliquely upward with the outer ring 207, wherein the outer ring 207 is elastic, and in the process of the outer ring 207 moving obliquely upward and expanding, it will squeeze the sliding plate 224, and the squeezed sliding plate 224 will move upward along the U-shaped groove 222 opened in the fixed block 221, and stretch the return spring 225, and the upward movement of the sliding plate 224 will press the elastic The elastic strip 223 is squeezed, wherein the elastic strip 223 is elastic, and its other end is connected to the bottom connecting rod 226, so the bottom connecting rod 226 will move downward along the limiting plate 227, and the bottom of the bottom connecting rod 226 is connected to the circular ring 301, so the circular ring 301 will move downward with the multi-disc ring 30, and the bottom of the multi-disc ring 30 is connected to the top rod 38, so the top rod 38 will move downward with the blocking tube 35, so that the blocking tube 35 will extend outward from the bottom of the sprinkler head 34.

[0064] As the ring 301 moves downward, the vertical rod 305 connected to the bottom thereof will move downward with the plug board 304, and then the plug board 304 will extend downward from the sleeve handle 303 and block the airflow to avoid interference with the cleaning liquid.

[0065] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
