[0052] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail.

[0053] This application provides an external surface wall-climbing cleaning device, which mainly includes an external guide rail 1, a lead screw motor 2, a lead screw 3, a steering motor 4, an external support 5, an external suction cup 6, an external pump 7, an internal guide rail 8, a drive motor 9, a gear 10, an internal support 11, an internal suction cup 12, an internal pump 13, a support plate 14, a cleaning water tank 15, a roller brush 16, a rolling motor 17, a roller 18, an internal support beam 19, an external support beam 20, a transmission bar 21, a transmission wheel 22, and a rotating cleaning brush 23. The whole device can be divided into three main parts: an external guide rail movement mechanism, an internal guide rail movement mechanism, and a cleaning mechanism.

[0054] The outer guide rail motion mechanism includes an outer guide rail 1, a lead screw motor 2, a lead screw 3, a steering motor 4, an outer bracket 5, an outer suction cup 6, and an outer pump 7. Each outer guide rail 1 has a gear guide groove and three lead screw motor mounting grooves. The lead screw motor 2 is installed in the lead screw motor mounting groove, and the lead screw 3 cooperates with the lead screw motor 2. The bottom of the lead screw 3 has a motor shaft mounting hole. The outer bracket 5 is provided with a steering motor groove, and the steering motor 4 is located between the motor shaft mounting hole and the steering motor groove. Four outer suction cups 6 are installed on the outer bracket 5. The outer pump 7 is located next to the lead screw motor 2. The outer suction cups 6 achieve lifting and lowering actions under the drive of the lead screw motor 2 and the lead screw 3.

[0055] The inner guide rail motion mechanism includes an inner guide rail 8, a drive motor 9, a gear 10, an inner support 11, an inner suction cup 12, an inner pump 13, a support plate 14, and a cleaning water tank 15. Each inner guide rail 8 has a roller guide groove and two drive motor grooves. The drive motor 9 is installed in the drive motor groove, and the gear 10 is installed on the drive motor 9. The gear 10 meshes with the gear guide groove. The inner support 11 is set on the inner guide rail 8, the inner suction cup 12 is installed on the inner support 11, the support plate 14 is set on the inner guide rail 8, the inner pump 13 is located at the bottom of the support plate 14, and the cleaning water tank 15 is located at the top of the support plate 14.

[0056] The cleaning mechanism includes a roller brush 16, a rolling motor 17, rollers 18, an inner support beam 19, an outer support beam 20, transmission bars 21, transmission wheels 22, and rotating cleaning brushes 23. The roller brush 16 has rolling motor slots at both ends, and the rolling motor 17 is installed within these slots. The rollers 18 are mounted on the motor shaft of the rolling motor 17 and located within the roller guide rails. The inner support beam 19 connects to the front ends of two inner guide rails 8, and the outer support beam 20 connects to the inner ends of two outer guide rails 1. Three transmission bars 21 are fixed to the inner support beam 19. The connecting rods of the three rotating cleaning brushes 23 pass through through holes in the outer support beam 20. The transmission wheels 22 are installed at the top of the connecting rods of the rotating cleaning brushes 23 and mesh with the transmission bars 21. The inner support beam 19 connects the transmission bars 21 to the inner guide rails 8, and the outer support beam 20 connects the transmission wheels 22, causing them to move synchronously with the outer guide rails 1.

[0057] The aforementioned external surface wall-climbing cleaning device has omnidirectional movement capability, and its specific operation is as follows:

[0058] Start the lead screw motor 2, drive the lead screw 3 to move downward, so that the steering motor 4 and the outer bracket 5 extend downward until the outer suction cup 6 is attached to the outer surface of the aircraft. Stop the lead screw motor 3, start the outer suction pump 7, so that the outer suction cup 6 is attached to the outer surface of the aircraft, ensuring that the entire device will not fall off the outer surface of the aircraft. At this time, the two outer guide rails 1 are fixed to the outer surface of the aircraft.

[0059] After the outer suction cup 6 is successfully attached to the outer surface of the aircraft, the drive motor 9 can be started, and the drive gear 10 can be moved back and forth in the gear guide groove, thereby driving the two inner guide rails 8 to move back and forth. When the inner guide rails 8 reach their limit positions, the lead screw motor 2 is started, and the lead screw 3 is driven to retract upward, thereby driving the steering motor 4 and the outer bracket 5 to retract upward until the outer suction cup 6 and the inner suction cup 12 are on the same plane. The lead screw motor 2 is turned off, and the inner pump 13 is started, so that the inner suction cup 12 is attached to the outer surface of the aircraft. The outer pump 7 is turned off, and the lead screw motor 2 is started, and the lead screw 3 continues to retract upward, driving the steering motor 4 and the outer bracket 5 to continue to retract upward until the outer suction cup 6 is detached from the outer surface of the aircraft. The lead screw motor 2 is turned off. At this time, the entire device is attached to the outer surface of the aircraft by the inner suction cup 12, and the two inner guide rails 8 are fixed to the surface of the aircraft.

[0060] After the inner suction cup 12 is successfully attached to the outer surface of the aircraft, the drive motor 9 can be started to drive the gear 10 to rotate, causing the two outer guide rails 1 to move back and forth. After the outer guide rails 1 reach their limit positions, the inner pump 13 can be turned off, causing the inner suction cup 12 to detach from the outer surface of the aircraft. By continuously repeating the process of the outer suction cup 6 and the inner suction cup 12 attaching and detaching from the outer surface of the aircraft, as well as the relative movement between the outer guide rails 1 and the inner guide rails 8, the overall forward and backward movement of the device can be achieved.

[0061] After the outer suction cup 6 is successfully attached to the outer surface of the aircraft, the corresponding steering motor 4 can be activated to rotate the entire device at any angle, achieving rotation in any direction. Combined with the forward and backward movement of the entire device, the entire device can move in all directions on the surface of the aircraft.

[0062] The above-mentioned external surface wall-climbing cleaning device is used to clean the aircraft surface. The specific process is as follows:

[0063] After the outer suction cup 6 is successfully attached to the outer surface of the aircraft, the rolling motor 17 can be started to drive the roller 18 to roll along the roller guide groove, so that the roller brush 16 moves back and forth and uses the cleaning liquid flowing out of the cleaning water tank 15 to clean the outer surface of the aircraft.

[0064] When the inner guide rail 8 moves back and forth, the transmission bar 21 moves back and forth accordingly, which can drive the transmission wheel 22 to rotate, thereby causing the rotating cleaning brush 23 to rotate, assisting in cleaning the outer surface of the aircraft. This process can be carried out before the roller brush 16 cleans the outer surface of the aircraft, so as to improve the cleaning effect on the outer surface of the aircraft and effectively utilize the energy of the inner guide rail 8 moving back and forth. When the outer guide rail 1 moves back and forth, it has the same effect.

[0065] The omnidirectional movement and cleaning process of the aforementioned external surface wall-climbing cleaning device on the aircraft surface can be controlled by a remote controller, which has a high degree of safety. The inner suction cup 12 can be a large suction cup to ensure the adsorption capacity. The roller 18 can be made of a high-precision wear-resistant engineering plastic material with a certain degree of elasticity to reduce friction, wear and noise caused by rigid contact transmission. In addition, considering the limited capacity of the cleaning water tank 15, the roller brush 16 can be designed to be made of a soft and absorbent material to improve the efficiency of cleaning agent use.

[0066] The aforementioned external surface wall-climbing cleaning device, through the design of its inner and outer guide rails, motor, and suction cups, has omnidirectional movement capability on the aircraft's external surface. It can quickly climb on large curved surfaces or flat surfaces, and is designed to use roller brushes to perform all-round cleaning of the aircraft's external surface by rotating and translating within the overall movement range of the device. It is convenient, fast, safe, and efficient.

[0067] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
