Description

Technical Field

[0001] This invention relates to the field of power equipment maintenance technology, and in particular to a power equipment spraying device based on a drone. Background Technology

[0002] In power system operation and maintenance, equipment such as insulators, conductors, and towers often require spraying operations for anti-pollution flashover, rust prevention, and insulation repair. Traditional manual spraying methods suffer from problems such as high-altitude operation risks, low efficiency, and inconsistent spraying quality.

[0003] Existing drone-based painting devices typically employ a single nozzle structure, limiting them to a fixed spray pattern. When dealing with different equipment, surface conditions, or environments, manual nozzle replacement or spray angle adjustments are required, resulting in complex and inefficient operations. Furthermore, existing painting devices lack a self-cleaning mechanism, leaving some paint residue inside the spray tube after each use. This residue is difficult to remove and, over time, dries and hardens on the inner wall of the spray tube, increasing the difficulty of subsequent cleaning. With repeated drying, blockages can occur inside the spray tube, affecting the normal operation of the painting device. Therefore, providing a drone-based power equipment painting device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The technical problem to be solved and the technical task proposed by this invention is to improve and refine existing technical solutions, and to provide a drone-based power equipment spraying device that can self-clean the spraying components, prevent the spray nozzle from drying and clogging, and simultaneously achieve the purpose of spraying angle adjustment and paint switching. To this end, this invention adopts the following technical solution: A drone-based electrical equipment spraying device includes: The drone body has two landing gears fixedly connected to the two sides of its lower end for support. The front of the drone body is connected to an observation component for real-time ranging. The bottom of the drone body is fixedly installed with an adjustment component for angle adjustment. The front end and the inside of the adjustment component are both connected to a self-cleaning spraying component. The spraying assembly includes a partitioning unit, a painting unit, and a self-cleaning unit. The partitioning unit is located at the rear of the inner cavity of the adjustment assembly, the painting unit is installed on the front of the adjustment assembly, and the self-cleaning unit is located inside the front end of the adjustment assembly.

[0005] This technical solution features a self-cleaning unit within its spraying assembly, which automatically cleans the spraying unit after use, effectively preventing residual paint from drying and clogging the spray nozzles, significantly extending the device's lifespan and reducing maintenance frequency. A partitioning unit allows for the separate storage of different paints and cleaning water, facilitating quick paint switching based on operational needs and providing an independent water source for the self-cleaning unit, ensuring that cleaning and spraying do not interfere with each other. Adjusting the assembly allows for changing the spraying angle, enabling the device to flexibly meet the spraying requirements of different parts of power equipment and improve operational adaptability. An observation assembly monitors the spraying area in real time and maintains a precise distance from the object being sprayed, thereby controlling spraying quality and preventing defects caused by excessive distance or proximity. The entire assembly is mounted on the UAV, replacing manual labor for high-altitude power equipment spraying, eliminating the safety hazards of personnel working at heights, while the landing gear ensures stable takeoff and landing of the UAV.

[0006] As a preferred embodiment of the present invention, the observation component includes two upper mounting plates. The rear ends of the two upper mounting plates are fixedly connected to both sides of the front of the UAV body.

[0009] As a preferred embodiment of the present invention, the partitioning unit includes a compartment plate, which is fixedly connected to the inner wall of the rear end of the regulating main box, dividing the regulating main box into three chambers. The chamber located in the upper left corner is paint chamber one, the chamber located in the upper right corner is paint chamber two, and the chamber located at the bottom is water chamber. The back of the upper end of the regulating main box is provided with two paint inlets communicating with paint chamber one and paint chamber two, and the back of the lower end of the regulating main box is provided with a water inlet communicating with water chamber.

[0010] As a preferred embodiment of the present invention, the painting unit includes a conversion spindle with a cuboid front end. The rear end of the conversion spindle is rotatably connected to the center of the front of the adjustment main box via a bearing. A second servo motor is fixedly installed at the center of the front surface of the inner cavity of the adjustment main box, and the output shaft of the front end of the second servo motor is fixedly connected to the rear end of the conversion spindle. A rotating carrier plate is movably sleeved on the front surface of the conversion spindle. An adjustment cylinder is fixedly installed at the bottom of the front surface of the inner cavity of the adjustment main box. An adjustment plate is rotatably connected to the outer surface of the rear end of the rotating carrier plate via a bearing, and the back of the lower end of the adjustment plate is fixedly connected to the piston rod at the front end of the adjustment cylinder.

[0011] As a preferred embodiment of the present invention, the front of the rotating carrier is embedded with four spray tubes arranged in a circular array. Each spray tube has a nozzle installed at its front end, and the nozzles arranged in sequence from the top along the direction of rotation are nozzle one, nozzle two, nozzle three, and nozzle four.

[0012] As a preferred embodiment of the present invention, the first nozzle is a diffusion spray nozzle, the second nozzle is a columnar spray nozzle, the third nozzle is a fan-shaped spray nozzle, and the fourth nozzle is a cone-shaped spray nozzle.

[0013] As a preferred embodiment of the present invention, the upper front of the compartment plate is provided with two separate extraction pipes that are respectively connected to the first and second paint compartment chambers. A solenoid valve 1 for controlling the opening and closing of its left channel is fixedly installed on the upper surface of the left end of the extraction pipe, and a solenoid valve 2 for controlling the opening and closing of its right channel is fixedly installed on the upper surface of the right end of the extraction pipe. A paint pump is fixedly installed on the top of the front surface of the inner cavity of the regulating main box. The liquid extraction port at the rear end of the paint pump is connected to the front end of the extraction pipe. A connecting pipe 1 that engages with one of the spray pipes is embedded in the front of the upper end of the regulating main box.

[0014] As a preferred embodiment of the present invention, the self-cleaning unit includes a water pump. The bottom of the water pump is fixedly installed on the bottom surface of the inner cavity of the front end of the regulating main box. A water pumping pipe communicating with the water tank chamber is provided on the front side of the lower end of the compartment plate, and the front end of the water pumping pipe is connected to the water pumping port at the rear end of the water pump. A connecting pipe two that engages with one of the spray pipes is embedded in the front side of the right end of the regulating main box, and the rear end of the connecting pipe two is connected to the drain port at the upper end of the water pump.

[0015] Beneficial effects: This invention, through its observation components, firstly allows for real-time observation of the spraying area and control of the spraying distance via a high-definition camera and a laser rangefinder, thereby increasing the spraying quality of the spraying device. Secondly, controlling the start of a stepper motor enables the high-definition camera and laser rangefinder to rotate synchronously forward or backward. By adjusting the forward and reverse rotation of the high-definition camera and laser rangefinder, the observation angle can be adjusted in a timely manner, facilitating timely adjustment of the spraying position of the spraying equipment and greatly improving the practicality of the spraying device.

[0016] This invention utilizes an adjustment component. First, controlling the servo motor to rotate forward drives the adjustment shaft and the main adjustment box to rotate forward 90° simultaneously. The main adjustment box rotating forward 90° drives the spraying component to rotate forward 90°, which in turn moves the spraying end of the spraying component directly downward. This allows for rapid adjustment of the spraying angle, enabling the spraying device to adapt to different spraying environments and improving the user experience. Then, controlling the positioning cylinder to activate moves the locking rod to the left. When the left end of the locking rod is fully inside the positioning slot, the spraying component after angle adjustment is repositioned, significantly improving the stability of the spraying device during operation.

[0017] This invention, through its partitioned unit, firstly divides the chamber behind the main control box into three chambers using a compartmentalized plate. Different paints can be placed in the first and second paint chambers, enabling the spraying device to quickly change paints for different spraying objects, thus improving the practicality of the spraying device. Secondly, the water tank can provide water to the self-cleaning unit, enabling the self-cleaning unit to be used continuously and effectively improving the service life of the spraying device.

[0018] This invention utilizes a specially designed painting unit. First, it controls the opening and closing of solenoid valves one and two, allowing for rapid opening and closing of the channels at both ends of the extraction pipe. This facilitates the selection of the desired paint. Then, starting the paint pump drives the extraction pipe to draw paint from the corresponding chamber. The paint is then transported to the inside of the spray pipe via connecting pipe one. The corresponding nozzle on the spray pipe then sprays the paint onto the surface of the object being painted. The coordinated use of solenoid valves one and two, along with the paint pump, enables rapid paint switching. Finally, starting the adjusting cylinder moves the adjusting plate forward, which in turn moves the rotating carrier plate forward, ultimately moving the spray pipe forward. When the rear end of the spray tube disengages from the inner cavity of the connecting tube, the second servo motor is then started. The second servo motor drives the conversion spindle and the rotating carrier plate to rotate 90° simultaneously. The 90° rotation of the rotating carrier plate drives each of the four spray tubes to rotate 90°. The 90° rotation of the four spray tubes aligns the new spray tube with the position of the connecting tube. Then, the adjustment cylinder is started again, which drives the rear end of the new spray tube to engage with the inner cavity of the connecting tube. This allows for quick replacement of the spray tube. By replacing the spray tube, it is also convenient to replace different types of nozzles. This enables the spraying device to cope with spraying different equipment, different surfaces, and different environments. Moreover, this nozzle replacement method is simple to operate and highly efficient.

[0019] This invention utilizes a self-cleaning unit. First, the servo motor and the adjusting cylinder work together to switch the position of the used spray tube. The switched spray tube automatically engages with the inner cavity of the connecting pipe, thus connecting the connecting pipe to the used spray tube. Then, the water pump is activated, driving the water pipe to transfer water from the water tank to the connecting pipe, which then transfers the water to the spray tube. The water passing through the spray tube quickly washes away any residual paint in its channel and effectively cleans the corresponding nozzle. This ensures the spray tube is cleaned during the switching process, allowing for continuous use of the spraying device and significantly improving the overall user experience.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0041] like Figures 1-19 As shown, a power equipment spraying device based on a drone includes: a drone body 1, two landing gears 2 for support are fixedly connected to the two sides of the lower end of the drone body 1, an observation component 3 for real-time ranging is connected to the front of the front end of the drone body 1, an adjustment component 4 for angle adjustment is fixedly installed at the bottom of the drone body 1, and a self-cleaning spraying component 5 is connected to the front end and the interior of the adjustment component 4; the spraying component 5 includes a partitioning unit, a painting unit and a self-cleaning unit, the partitioning unit is located behind the interior of the adjustment component 4, the painting unit is installed on the front of the adjustment component 4, and the self-cleaning unit is located inside the front end of the adjustment component 4.

[0042] like Figure 3 , Figure 12 , Figure 13 , Figure 19As shown, the observation component 3 includes two upper mounting plates 301. The rear ends of the two upper mounting plates 301 are fixedly connected to the two sides of the front of the UAV body 1. The middle of the side of each upper mounting plate 301 is rotatably connected to a high-definition camera 302 for observing the paint spraying area via a bearing. A laser rangefinder 303 for measuring the distance of the sprayed object is fixedly installed on the top of the high-definition camera 302. A stepper motor 304 is fixedly installed on the right side of the upper mounting plate 301, and the output shaft at the left end of the stepper motor 304 is fixedly connected to the rotating shaft at the right side of the high-definition camera 302 via a coupling.

[0043] like Figure 5 , Figure 6 , Figure 10 , Figure 16 As shown, the adjustment assembly 4 includes a fixed bracket 401. The upper end of the fixed bracket 401 is fixedly connected to the bottom of the UAV body 1 by multiple bolts. Two adjustment shafts 402 are rotatably connected to the opposite sides of the lower end of the fixed bracket 401 by bearings. A servo motor 403 is fixedly installed in the middle of the left side of the fixed bracket 401, and the output end of the servo motor 403 on the right side is fixedly connected to the left end of the adjustment shaft 402 on the left side by a coupling. An adjustment main box 404 with a door is fixedly connected to the end of each of the two adjustment shafts 402 that are close to each other. A square positioning slot 405 is opened on the right end of the adjustment shaft 402 on the right side. A positioning cylinder 406 is fixedly installed on the right side of the lower end of the fixed bracket 401. A locking rod 407 that fits into the inner cavity of the positioning slot 405 is fixedly connected to the piston rod on the left side of the positioning cylinder 406.

[0044] The positioning slot 405 is square in shape. This allows the positioning slot 405 to be easily inserted into the chamber of the main box 404 after the main box 404 rotates the adjusting shaft 402 by 90 degrees. This effectively improves the stability of the spraying assembly 5 after angle adjustment.

[0045] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 14 As shown, the partition unit includes a compartment plate 501, which is fixedly connected to the inner wall of the rear end of the regulating main box 404, dividing the regulating main box 404 into three chambers. The chamber located in the upper left corner is paint chamber 1 502, the chamber located in the upper right corner is paint chamber 2 503, and the chamber located at the bottom is water chamber 504. The upper back of the regulating main box 404 is provided with two paint inlets 505 that communicate with the paint chamber 1 502 and paint chamber 2 503, and the lower back of the regulating main box 404 is provided with a water inlet 506 that communicates with the water chamber 504.

[0046] like Figure 7 , Figure 9 , Figure 10 , Figure 12 , Figure 14 , Figure 17 , Figure 19 As shown, the painting unit includes a conversion spindle 507 with a cuboid front end. The rear end of the conversion spindle 507 is rotatably connected to the center of the front of the adjustment main housing 404 via a bearing. A servo motor 508 is fixedly mounted at the center of the front surface of the inner cavity of the adjustment main housing 404, and the output shaft of the front end of the servo motor 508 is fixedly connected to the rear end of the conversion spindle 507. A rotating carrier plate 509 is movably sleeved on the front surface of the conversion spindle 507. A rotating carrier plate 509 is fixedly mounted at the bottom of the front surface of the inner cavity of the adjustment main housing 404. There is an adjusting cylinder 515. The outer surface of the rear end of the rotating carrier 509 is rotatably connected to the adjusting plate 516 via a bearing. The back of the lower end of the adjusting plate 516 is fixedly connected to the piston rod at the front end of the adjusting cylinder 515. The front of the rotating carrier 509 is embedded with four spray tubes 510 arranged in a circular array. Each spray tube 510 has a nozzle installed at its front end. The nozzles from the top along the forward rotation direction are nozzle one 511, nozzle two 512, nozzle three 513, and nozzle four 514.

[0047] like Figure 12 , Figure 14 , Figure 15 As shown, nozzle 1 511 is a diffusion spray nozzle, nozzle 2 512 is a columnar spray nozzle, nozzle 3 513 is a fan-shaped spray nozzle, and nozzle 4 514 is a cone-shaped spray nozzle.

[0048] like Figure 17 As shown, on both sides of the upper front of the compartment plate 501, there are separate extraction pipes 517 that communicate with the first paint compartment 502 and the second paint compartment 503, respectively. A solenoid valve 518 is fixedly installed on the upper surface of the left end of the extraction pipe 517 to control the opening and closing of its left channel, and a solenoid valve 519 is fixedly installed on the upper surface of the right end of the extraction pipe 517 to control the opening and closing of its right channel. A paint pump 520 is fixedly installed on the top of the front surface of the inner cavity of the main regulating chamber 404. The liquid extraction port at the rear end of the paint pump 520 is connected to the front end of the extraction pipes 517. The upper front of the main regulating chamber 404... The self-cleaning unit includes a water pump 522, the bottom of which is fixedly installed on the bottom surface of the front cavity of the main regulating box 404. A water suction pipe 523 communicating with the water tank 504 is provided on the front of the lower end of the compartment plate 501, and the front end of the water suction pipe 523 is connected to the water suction port at the rear end of the water pump 522. A second connecting pipe 524 communicating with one of the spray pipes 510 is embedded in the front of the right end of the main regulating box 404, and the rear end of the second connecting pipe 524 is connected to the drain port at the upper end of the water pump 522.

[0049] Working principle: First, the drone body 1 starts, driving the entire spraying device to the vicinity of the power equipment. At this time, the high-definition camera 302 and the laser rangefinder 303 work together to observe the spraying area and control the spraying distance in real time, thus improving the spraying quality of the spraying device. Then, controlling the stepper motor 304 to start enables the high-definition camera 302 and the laser rangefinder 303 to rotate synchronously forward or backward. By controlling the forward and reverse rotation of the high-definition camera 302 and the laser rangefinder 303, their observation angle can be adjusted in a timely manner, thus facilitating timely adjustment of the spraying position of the spraying device. Finally, controlling the opening and closing of solenoid valve 518 and solenoid valve 519 respectively, the spraying process can be completed quickly. The opening and closing of the channels at both ends of the component extraction pipe 517, with solenoid valve one 518 open and solenoid valve two 519 closed, connects the extraction pipe 517 to the chamber of paint tank one 502. Conversely, with solenoid valve one 518 closed and solenoid valve two 519 open, the extraction pipe 517 connects to the chamber of paint tank two 503, facilitating the selection of the desired paint. Then, controlling the start of the paint pump 520 drives the extraction pipe 517 to extract the paint from the corresponding chamber, which is then transported to the spray pipe 510 via connecting pipe one 521. At this point, the corresponding nozzle one 511 on the spray pipe 510 can spray the paint onto the surface of the object being painted. The coordinated use of solenoid valve 518, solenoid valve 519, and paint pump 520 enables rapid paint switching and spraying. Finally, activating the adjusting cylinder 515 moves the adjusting plate 516 forward, which in turn moves the rotating carrier 509 forward. The rotating carrier 509 then moves the spray nozzle 510 forward. When the rear end of the spray nozzle 510 disengages from the inner cavity of the connecting pipe 521, servo motor 508 is activated. This activation drives the conversion spindle 507 and the rotating carrier 509 to simultaneously rotate 90° in reverse. The 90° rotation of the rotating carrier 509 then drives four... The spray tubes 510 are rotated 90° each. Rotating the four spray tubes 510 by 90° will align the new spray tube 510 with the first connecting tube 521. Then, the adjustment cylinder 515 is activated again, which will drive the rear end of the new spray tube 510 into the inner cavity of the first connecting tube 521. This allows for the quick replacement of the spray tubes 510. At this time, the second nozzle 512 corresponds to the position of the first connecting tube 521, and after rotation, the first nozzle 511 corresponds to the position of the second connecting tube 524. By replacing the spray tubes 510, it is convenient to replace different types of nozzles. This enables the spraying device to spray different equipment, different surfaces, and different environments. Vertical spraying of power equipment: First, controlling the servo motor 403 to rotate forward will drive the adjusting shaft 402 and the adjusting main box 404 to rotate forward 90° simultaneously. The adjusting main box 404 rotating forward 90° will drive the spraying component 5 to rotate forward 90°. The spraying component 5 rotating forward 90° will move its spraying end directly downward, thus quickly adjusting the spraying angle of the spraying component 5, thereby enabling the spraying device to perform vertical spraying of the power equipment. Then, controlling the positioning cylinder 406 to start will drive the locking rod 407 to move to the left. When the left end of the locking rod 407 is fully moved into the positioning slot 405, the spraying component 5 after angle adjustment can be repositioned, improving the spraying quality of the power equipment. Self-cleaning of spraying assembly 5: First, the servo motor 508 and the adjusting cylinder 515 work together to switch the position of the used spray tube 510. The switched spray tube 510 will automatically snap into the inner cavity of the connecting pipe 524, thus connecting the connecting pipe 524 with the used spray tube 510. Then, the water pump 522 is started, which drives the water pumping pipe 523 to transfer the water source in the water tank 504 to the inside of the connecting pipe 524. The connecting pipe 524 then transfers the water source to the inside of the spray tube 510. At this time, the water source inside the spray tube 510 can quickly complete the self-rinsing of the residual paint in its channel. At the same time, it can also effectively complete the self-cleaning of the corresponding nozzle. This enables the spray tube 510 to be cleaned during the switching process, thereby enabling the spraying device to be used continuously.
