[0033] The technical solution of the present application will be described below through specific embodiments.

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic structural diagram of a suspended operation spraying system provided by an embodiment of the present application, Figure 2 which shows a schematic structural diagram of a suspended spraying operation device in a suspended operation spraying system provided by an embodiment of the present application. The suspended operation spraying system specifically includes: an aircraft 100, a suspended spraying operation device 200 provided in a mounting area 110 of the aircraft. The suspended spraying operation device 200 includes: a driving and control box 210 and a liquid storage tank 220 provided in the mounting area 110 and close to the center of gravity position of the aircraft 100, and a variable-angle spraying assembly 240 connected to the driving and control box 210 and extending out of the coverage range of the aircraft 100 rotor through a horizontally arranged connecting rod 230.

[0035] In this embodiment, the suspended operation spraying system is used to perform high-altitude spraying operations on the objects to be sprayed on high-altitude facades (the objects to be sprayed can be understood as high-altitude objects, specifically building facades, wind turbine blades, photovoltaic panels, power towers and utility poles in the power distribution system, etc.). Specifically, after determining the location of the object to be sprayed, the aircraft 100 (such as a drone, etc.) is controlled to fly near the object to be sprayed, and then the variable-angle spraying assembly 240 connected to the connecting rod 230 is aligned with the object to be sprayed. Since the connecting rod 230 is a structural member with a certain length (specifically, the length of the connecting rod 230 is greater than the radius or diameter corresponding to the coverage range of the rotor of the aircraft 100), when the aircraft 100 is suspended and close to the object to be sprayed, the object to be sprayed is outside the coverage range of the rotor of the aircraft 100, effectively avoiding the problem that the rotor of the aircraft 100 collides with the object to be sprayed during suspension and preventing safe suspended operation spraying.

[0036] Moreover, during the specific operation of the suspended operation spraying system, if the current alignment angle of the variable-angle spraying assembly 240 is not sufficient to achieve full spraying of the object to be sprayed, the orientation can be changed to adjust the spraying range and cooperate with the aircraft 100 to achieve suspended spraying operations with full coverage of the object to be sprayed in a narrow space, thus coping with spraying operations in complex high-altitude environments. That is, the suspended operation spraying system can, according to the processing technology requirements of the object to be sprayed, spray the solution in the liquid storage tank 220 from the variable-angle spraying assembly 240 by the drive control box 210 according to a preset spraying mode, and the variable-angle spraying assembly 240 can actively adjust the change of the spraying angle according to the operation range of the spraying surface and / or the three-dimensional environment of the spraying surface.

[0037] For example, the suspended operation spraying system can specifically be used to clean or paint high-altitude objects to be sprayed. Specifically, if the object to be sprayed is a building facade, a wind turbine blade, a photovoltaic panel, etc., cleaning its surface is also a routine daily maintenance task. The cleaning liquid required for cleaning can be contained in the liquid storage tank 220. After the suspended operation spraying system flies to the corresponding target operation area of the building facade, wind turbine blade, photovoltaic panel, etc., the drive control box 210 sprays the cleaning liquid in the liquid storage tank 220 from the variable-angle spraying assembly 240 according to a preset spraying mode, and the variable-angle spraying assembly 240 can actively adjust the change of the spraying angle according to the operation range of the spraying surface and / or the three-dimensional environment of the building facade, wind turbine blade, photovoltaic panel, etc.

[0038] Specifically, when the object to be sprayed is a power tower or a utility pole in a power distribution system, repainting the insulating components is a routine maintenance task. The paint required for repainting can be contained in the liquid storage tank 220. After the aerial spraying system flies to the target operation area of the power tower or the utility pole in the power distribution system, the drive control box 210 sprays the paint in the liquid storage tank 220 from the variable-angle spraying component 240 according to a preset spraying mode, and the variable-angle spraying component 240 can actively adjust the spraying angle change according to the spraying surface operation range and / or the three-dimensional environment of the power tower or the utility pole.

[0039] In one embodiment, as Figures 1-6 shown, the variable-angle spraying component 240 includes a variable-angle liquid path 241 and a nozzle 242; the liquid path 241 includes an intermediate flow path 2411 and a rigid variable-bending flow path 2412 connected in sequence; the intermediate flow path 2411 is located inside the connecting rod 230 or on one side of the connecting rod 230; the root of the intermediate flow path 2411 is connected to the drive control box 210, and the end of the intermediate flow path 2411 is connected to the inlet end of the rigid variable-bending flow path 2412; the outlet end of the rigid variable-bending flow path 2412 is connected to the nozzle 242.

[0040] In this embodiment, the rigid variable-bending flow path 2412 is made of a hard material, which is convenient for improving the rigidity of the liquid path 241; moreover, the rigid variable-bending flow path 2412 enables the end of the liquid path 241 to be adjustable, that is, it can be adjusted according to the position of the specific spraying target surface of the object to be sprayed, so that the nozzle 242 changes with the orientation of the outlet end, thereby realizing precise spraying of the object to be sprayed.

[0041] In one embodiment, as Figures 1-6 shown, the end of the intermediate flow path 2411 has a rigid connection end, and the rigid connection end is fixedly connected or integrally provided with the end of the connecting rod 230; the inlet end of the rigid variable-bending flow path 2412 is rotatably connected to the rigid connection end, and the axis direction of the rotational connection is parallel to the liquid flow direction in the inlet end; the inlet end and the outlet end of the rigid variable-bending flow path 2412 are arranged at an angle.

[0042] In this embodiment, when the rigid variable-bending flow path 2412 rotates, the orientation of the nozzle 242 changes with the change of the orientation of the outlet end of the rigid variable-bending flow path 2412, and at the same time, the intermediate flow path 2411 and the connecting rod 230 maintain a consistent stable pose, making the overall aerial spraying system more stable.

[0043] In one embodiment, as Figures 1-6As shown, the variable-angle spraying assembly 240 further includes a first rotating assembly 243; the rigid variable-bending flow channel 2412 includes a first variable section 24121 having a first inlet end 24121A and a first outlet end 24121B, the first inlet end 24121A and the first outlet end 24121B are arranged at an angle, the first rotating assembly 243 drives the first variable section 24121 to rotate, and the rotation axis is parallel to the axis of the first inlet end 24121A.

[0044] In this embodiment, with the above arrangement, the rigid variable-bending flow channel 2412 is rotated by the first rotating assembly 243, so that the liquid path 241 is adjustable; in addition, the rotation axis being parallel to the axis of the first inlet end 24121A can effectively improve the stability of the entire variable-angle spraying assembly 240 when adjusting the orientation of the nozzle 242, so as to ensure stable and accurate spraying of the object to be sprayed.

[0045] In one embodiment, as Figures 1-6 shown, the variable-angle spraying assembly 240 further includes a second rotating assembly 244; the rigid variable-bending flow channel 2412 further includes a second variable section 24122 having a second inlet end 24122A and a second outlet end 24122B, the second inlet end 24122A and the second outlet end 24122B are arranged at an angle, the second rotating assembly 244 drives the second variable section 24122 to rotate, and the rotation axis is parallel to the axis of the second inlet end 24122A;

[0046] The first inlet end 24121A is rotatably connected to the end of the intermediate flow channel 2411, the first outlet end 24121B is rotatably connected to the second inlet end 24122B coaxially, and the second outlet end 24122B is connected to the nozzle 242.

[0047] In this embodiment, the variable-angle spraying assembly 240 includes both the first rotating assembly 243 and the second rotating assembly 244. By arranging the above two sets of rotating assemblies, the rigid variable-bending flow channel 2412 is rotated in different directions, so that a larger spraying angle and a larger spraying range can be achieved to meet the operation requirements of suspended spraying operations in complex scenarios.

[0048] Among them, the rotation directions of the first rotating component 243 and the second rotating component 244 are perpendicular to each other; that is, there are two cases. The first case is that the rotation direction of the first rotating component 243 is the vertical direction and the rotation direction of the second rotating component 244 is the horizontal direction; the second case is that the rotation direction of the first rotating component 243 is the horizontal direction and the rotation direction of the second rotating component 244 is the vertical direction. Through the cooperation of the rotation directions of the first rotating component 243 and the second rotating component 244, the adjustment of the orientation of the entire liquid path 241 and the nozzle 242 can be provided to the greatest extent, so that any surface of the object to be sprayed can be sprayed.

[0049] In one embodiment, as Figures 1-6 shown, the variable-angle spraying assembly 240 further includes a mounting seat 245. The mounting seat 245 is connected to the intermediate flow path 2411, and the end of the intermediate flow path 2411 penetrates through one end of the mounting seat 245. The end of the connecting rod 230 is connected to the mounting seat 245, and the intermediate flow path 2411 is arranged along the connecting rod 230; the length of the intermediate flow path 2411 is greater than the length of the rigid variable-bending flow path 2412.

[0050] In this embodiment, the middle part of the connecting rod 230 can be bent. Since the intermediate flow path 2411 is relatively long, a connecting rod 230 with a longer length is required for auxiliary fixation. During transportation, the space occupied by the too-long connecting rod 230 is relatively large, so it is set to be bendable, which is convenient for transportation and effectively prevents damage or breakage of the connecting rod 230 during transportation. In specific implementation, the intermediate flow path 2411 can also be arranged inside the connecting rod 230. And in other embodiments, the intermediate flow path 2411 can be a rigid flow path. At this time, the intermediate flow path 2411 not only has the function of conveying the spraying material, but also has the function of connecting the driving and control box 210 and the mounting seat 245.

[0051] In one embodiment, as Figures 1-6 shown, the mounting seat 245 has a fixed end 2451 arranged oppositely and a connecting end 2452 connecting the two fixed ends 2451. An installation space is formed between the two fixed ends 2451, and a support portion 2453 is provided on the connecting end 2452. The support portion 2453 is located in the installation space;

[0052] The first rotating assembly 243 includes a first servo 2431. The first inlet end 24121A is rotatably connected to the end of the intermediate flow channel 2411 at the support portion 2453. The first servo 2431 is provided on the fixed end 2451 away from the intermediate flow channel 2411, and the rotating shaft of the first servo 2431 is coaxially arranged with the first inlet end 24121A. The first servo 2431 is connected to the drive control box 210 through a first wire, and the first wire is arranged along the connecting rod 230 and the mounting seat 245. The first servo 2431 is used to control the first variable section 24121 to rotate in the vertical direction;

[0053] The fixed end 2451 provided with the first servo 2431 is also rotatably provided with a mounting bracket 246. The mounting bracket 246 rotates following the rotation of the first variable section 24121. The first variable section 24121 is fixedly connected to the mounting bracket 246. The second variable section 24122 is rotatably connected or in clearance fit with the mounting bracket 246. The mounting bracket 246 has two angled inner cavities, and each inner cavity respectively wraps different angled parts of the first variable section 24121;

[0054] The second rotating assembly 244 includes a second servo 2441. The second servo 2441 is connected to the mounting bracket 246. The second servo 2441 is connected to the drive control box 210 through a second wire, and the second wire is arranged inside the connecting rod 230, the mounting seat 245, and the mounting bracket 246. The second servo 2441 is used to control the rotation of the second variable section 24122, and the rotation direction of the second variable section 24122 is perpendicular to the rotation direction of the first variable section 24121;

[0055] The first rotating assembly 243 includes a wire winding guard plate 2432. The wire winding guard plate 2432 is arranged at the corresponding position of the first servo 2431. The wire winding guard plate 2432 provides a winding space for the first wire to prevent interference of the first wire during rotation, resulting in extrusion damage.

[0056] In this embodiment, the mounting bracket 246 and the first variable section 24121 are connected as a whole, which can enhance the control and adjustment of the rotation of the first variable section 24121.

[0057] Moreover, specifically by connecting the power supply in the drive control box 210 through the first wire and the second wire, it is not necessary to add an additional power supply at the mounting seat 245, thereby reducing the load at the end of the variable-angle spraying assembly 240.

[0058] Among them, as Figures 1-6As shown, the fixed end 2451 is provided with an arc-shaped positioning groove 24511. The arc-shaped positioning groove 24511 is located on the side of the fixed end 2451 close to the installation space. The mounting bracket 246 is provided with a positioning protrusion 2461 extending into the arc-shaped positioning groove 24511. The positioning protrusion 2461 rotates within the arc-shaped positioning groove 24511, and the rotation angle is ±90°. The rotation angle of the first variable section 24121 can be roughly judged from the relative positions of the positioning protrusion 2461 and the arc-shaped positioning groove 24511. In some embodiments, angle scales can also be provided on the periphery of the arc-shaped positioning groove 24511, so that the rotation angle of the first variable section 24121 can be read in real time, in order to accurately adjust the rotation amplitude of the first variable section 24121.

[0059] The wire-winding guard plate 2432 is arranged between the first servo motor inside the fixed end 2451 of the mounting base and the positioning protrusion 2461, close to the rotating shaft of the first servo motor. The first wire passes through the positioning protrusion 2461 and enters the inside of the mounting bracket 246. When the positioning protrusion 2461 drives one end of the first wire to rotate along the arc-shaped groove, the part of the first wire outside the positioning protrusion 2461 rotates between the inside of the side of the fixed end 2451 where the arc-shaped positioning groove 24511 is opened and the wire-winding guard plate 2432 without being interfered / squeezed or wound.

[0060] Among them, in some other embodiments, the first rotating assembly 243 is arranged on the driving and controlling box 210 or the connecting rod 230. The first rotating assembly 243 is connected to the end of the first inlet end 24121A and the intermediate flow channel 2411 through a first transmission member, so as to drive the first variable section 24121 to rotate around the axis of the first inlet end 24121A. The second rotating assembly 244 is arranged on the driving and controlling box 210 or the connecting rod 230. The second rotating assembly 244 is connected to the first outlet end 24121B and the second inlet end 24122A through a second transmission member, so as to drive the second variable section 24122 to rotate around the axis of the second inlet end 24122A. Through the above settings, the weight at the end of the variable-angle spraying assembly 240 can be further reduced, thereby improving the sensitivity and operability of the rotation adjustment of the variable-angle spraying assembly 240, and the first transmission member and the second transmission member include one of a pull rope, a belt, and a timing belt.

[0061] In one embodiment, as Figures 1-6 shown, the driving and controlling box 210 includes a control box base 211, a control box 212, and a fluid pump (not shown); the control box base 211 is fixed to the mounting area 110 of the aircraft 100; the control box 212 is arranged on the control box base 211; the fluid pump is arranged inside the control box 212 and is used to pump out the liquid stored in the liquid storage tank 220 to the variable-angle spraying assembly 240.

[0062] In this embodiment, a control box base 211 and a control box 212 are specifically arranged in the drive and control box 210. The control box 212 is stably fixed to the mounting area 110 of the aircraft 100 through the control box base 211. Specifically, the control box 212 is stably fixed to the mounting area 110 near the center of gravity position of the aircraft 100 through the control box base 211, so that the center of gravity of the entire system is basically concentrated at the center of gravity position of the aircraft 100, which can improve the stability of the movement of the entire system.

[0063] Among them, a first control module for controlling the angles and relative positions between the aircraft 100 and the nozzle 242 by the first rotation assembly 243 and / or the second rotation assembly 244, and a second control module for controlling the opening and closing of the variable-angle spraying assembly 240 are further arranged in the control box 212. The first control module is electrically connected to the first rotation assembly 243 and / or the second rotation assembly 244, and the second control module is electrically connected to the variable-angle spraying assembly 240.

[0064] Moreover, a first wireless control module wirelessly communicatively connected to the first control module and a second wireless control module wirelessly communicatively connected to the second control module are both integrally arranged on the operation handle of the aircraft 100. While the aircraft 100 can be controlled in real time through the operation handle, the adjustment of the orientation of the liquid path 241 and the nozzle 242 can be realized based on the interaction between the first wireless control module and the first control module and the interaction between the second wireless control module and the second control module, so that it faces the target surface of the object to be sprayed in the best pose, realizing accurate and full-coverage spraying operations.

[0065] In one embodiment, as Figures 1-6 shown, the liquid storage tank 220 includes a liquid storage tank support base 221 and a liquid storage tank body 222; the liquid storage tank support base 221 is fixed to the mounting area 110 of the aircraft 100 and is located on one side of the control box base 211; the liquid storage tank body 222 is fixed on the liquid storage tank support base 221.

[0066] In this embodiment, the liquid storage tank body 222 is fixed to the mounting area 110 through the liquid storage tank support base 221.

The root of the connecting rod 230 is also connected to the control box 212.

[0068] In this embodiment, in order to improve the stability of the control box base 211 as a support structure, a first spraying component support frame 2111 and a second spraying component support frame 2112 may be specifically arranged at intervals on the control box base 211. Through this arrangement, both ends of the control box 212 are supported and fixed by the first spraying component support frame 2111 and the second spraying component support frame 2112 respectively, realizing the firm fixation of the control box 212. Moreover, the root of the connecting rod 230 can penetrate through the first spraying component support frame 2111 and the second spraying component support frame 2112 and be fixed on the first spraying component support frame 2111 and the second spraying component support frame 2112, and the root of the connecting rod 230 is also connected to the control box 212, so that the connecting rod 230 is more firmly supported in the above manner.
