[0002] As modern architecture becomes increasingly taller and more complex, the cleaning and maintenance of the exterior glass facades of high-rise buildings has become an important and challenging task. Traditional high-altitude window cleaning operations mostly rely on manual hanging methods, which are not only labor-intensive and inefficient but also pose significant safety risks. To address these issues, technological solutions utilizing drones or automated equipment for high-altitude cleaning have gradually emerged in recent years. Among these, drone-based high-altitude window cleaning devices have attracted widespread attention due to their flexibility and wide applicability. These devices typically involve attaching a cleaning module to a drone, enabling it to perform spraying and wiping cleaning operations on high-rise glass under remote control.

[0003] However, existing high-altitude window cleaning devices still have many shortcomings in practical applications. Especially in high-altitude environments, due to factors such as wind disturbances, control errors, or sudden malfunctions, drones are prone to losing control and falling during cleaning tasks, which may not only cause equipment damage but also pose serious safety hazards.

[0025] Example: A high-altitude window cleaning device to prevent falling, as shown in Figures 1, 2, 3, 4, 5, and 7, includes a support platform 14, a control module 22, an anti-fall component, a drone 1, wings 101, a protective cover 2, a connecting plate 3, a motor 4, a cleaning disc 5, a cleaning component, and a limiting component. The anti-fall component is located on the front of the support platform 14, and the control module 22 is installed on the rear of the support platform 14. Limiting pulleys are installed at the bottom of the support platform 14 to guide the support platform 14 to slide smoothly along the window edge and prevent it from deviating or tilting. The support platform 14 is connected to the drone 1 via the anti-fall component. The drone 1 has wings 101 arranged in an X-shape around its periphery. Each wing 101 of the drone 1 is equipped with a protective cover 2, which protects the wings 101 of the drone 1 and prevents them from being damaged by collision during window cleaning. A connecting plate 3 is bolted to the rear of the drone 1. Two motors 4 are symmetrically arranged on the upper and lower sides of the rear of the connecting plate 3. The output shaft of each motor 4 faces the rear and a cleaning disc 5 is bolted to the end of the output shaft. A cleaning component is provided on the rear of the drone 1. A limit component is provided between the support platform 14 and the anti-fall component. The motors 4 are electrically connected to the control module 22.

[0026] As shown in Figures 2, 3, and 4, the anti-fall component includes a rotating shaft 15, a winding reel 16, a connecting rope 17, and a connecting ring 18. The rotating shaft 15 is rotatably connected between the left and right sides of the upper front part of the support platform 14. Two sets of winding reels 16 are connected to the middle of the rotating shaft 15 by welding. The connecting rope 17 is wound on the winding reels 16. The connecting ring 18 is connected to the left and right sides of the top front part of the drone 1 by bolts. Both sets of connecting ropes 17 pass through the corresponding connecting rings 18 and are firmly connected to the drone 1.

[0027] As shown in Figures 4, 5, 6 and 7, the cleaning assembly includes a support plate 6, a liquid storage tank 7, a liquid pump 8, a nozzle 9 and a funnel 10. The support plate 6 is bolted to the left and right sides of the connecting plate 3. A liquid storage tank 7 is installed on each support plate 6. A liquid pump 8 is installed on the top of each liquid storage tank 7. The output end of the liquid pump 8 is connected to and communicates with the nozzle 9. The funnel 10 is bolted to the top of the rear side of the connecting plate 3 above the cleaning disc 5. Two nozzles 9 are staggered and set on the top of the funnel 10. The liquid pump 8 is electrically connected to the control module 22.

[0028] As shown in Figures 7 and 8, the system also includes a telescopic rod 12, a sponge block 11, and a return spring 13. The telescopic rod 12 is bolted to the left and right sides of the cleaning discs 5 located on the upper and lower sides of the connecting plate 3. The sponge block 11 is slidably connected between the rear ends of the telescopic rods 12 on both sides. The return spring 13 is connected between the sponge block 11 and the connecting plate 3. The sponge block 11 can assist in wiping the glass when the cleaning discs 5 are working, thereby improving the cleaning effect.

[0029] As shown in Figures 2 and 3, the limiting assembly includes a servo motor 19, a worm gear 20, and a worm wheel 21. The servo motor 19 with its output shaft facing forward is mounted on the upper part of the support platform 14. The worm gear 20 is connected to its output shaft by welding. The worm wheel 21 is connected to the outer periphery of the middle part of the rotating shaft 15 by welding. The worm wheel 21 and the worm gear 20 mesh with each other, and both the worm wheel 21 and the worm gear 20 are located between two sets of winding discs 16. The servo motor 19 is electrically connected to the control module 22.

[0030] Operators can apply the corresponding technical solutions in this device to high-altitude glass cleaning operations according to specific circumstances. When this device is needed to assist in high-altitude window cleaning operations, firstly, slide the support platform 14 to the roof position above the window to be cleaned via the limiting pulley, and lock the limiting pulley to prevent it from moving. Then, a counterweight can be placed on the support platform 14 to enhance overall stability. Next, one end of the connecting rope 17 of the drone 1 is fixed to the winding reel 16, and the other end is passed through the connecting ring 18 and securely connected to the drone 1. This secure connection can be achieved by, but is not limited to, knotting, binding, or snap-fit ​​connections to ensure that the connection structure has sufficient strength and stability during high-altitude operations.

[0031] The connecting rope 17 and winding reel 16 in the anti-drop assembly allow the drone 1 to be slowly released to the outside of the window at a corresponding height. Specifically, the servo motor 19 drives the worm gear 20 to rotate, which in turn drives the meshing worm wheel 21 to rotate synchronously, thereby controlling the rotation direction of the shaft 15 and the winding reel 16. This enables the orderly release or retrieval of the connecting rope 17, allowing the drone 1 to rise or fall stably to the target area. At this time, the operator can use a remote control to adjust the attitude of the drone 1, bringing the cleaning disc 5 on its rear side close to the glass surface.

[0032] During the cleaning process, when the operator controls the drone 1 via remote control, the high-speed rotation of the drone 1's wings 101 not only adjusts the drone 1's position but also performs preliminary dust removal on the glass surface. Then, the motor 4 drives the cleaning disc 5 to rotate at high speed, cleaning the glass surface. Simultaneously, the liquid pump 8 in the cleaning assembly draws liquid from two storage tanks 7 on either side, one containing cleaning fluid and the other containing water. The cleaning fluid is first evenly sprayed onto the funnel 10 area by the cleaning fluid nozzle 9, thus covering the cleaning area of ​​the cleaning disc 5 and improving the cleaning effect. Then, the water nozzle 9 continues to spray water to rinse away any remaining cleaning agent on the glass surface. After the spraying operation is completed, the sponge block 11 adheres tightly to the glass surface under the action of the return spring 13, automatically adapting to different glass thicknesses as the telescopic rod 12 adjusts elastically. Simultaneously, the drone 1 flies slowly, carrying the sponge block 11 to wipe the glass, achieving the final drying process.

[0033] Throughout the cleaning process, the protective cover 2 effectively protects the wing 101 from collision damage and prevents the connecting rope 17 from getting tangled in the rotating area, enhancing safety. In the event of emergencies such as wind disturbances or instability of the drone 1, the flexible connection structure in the anti-fall component provides cushioning to prevent the drone 1 from accidentally falling. After cleaning, the servo motor 19 reverses its direction, retracting the connecting rope 17 through the worm gear 21 and worm 20 transmission system, smoothly returning the drone 1 to the vicinity of the support platform 14 for subsequent transfer or maintenance.

[0034] In summary, this device not only achieves efficient cleaning of high-altitude glass, but also possesses good safety and controllability, making it suitable for exterior wall cleaning operations in various complex environments.
