[0031] The present invention provides an automatic decontamination system for an entire aircraft, comprising:

[0032] The decontamination device 1 comprises a moving track 101, a track car 102, an arm-type robot 103 arranged on the track car 102, a first drying fan 104, and a first decontamination pump 105. The track car 102 is slidably arranged on the moving track 101. The arm-type robot 103 is connected to a first nozzle 106. The first decontamination pump 105 is connected to the first nozzle 106. The first decontamination fan 104 is connected to a first blowing pipe 107. The first nozzle 106 can spray decontamination liquid to the aircraft. The first blowing pipe 107 can convey dry airflow to the aircraft.

[0033] The aircraft towing device 2 includes an omnidirectional mobile platform 201, a second decontamination pump 202, a second drying fan and a second nozzle 203. The omnidirectional mobile platform 201 can support the entire aircraft. A drag wheel 205 is arranged at the bottom of the omnidirectional mobile platform 201. The drag wheel 205 can drive the omnidirectional mobile platform 201 to rotate and slide. The second decontamination pump 202 is slidably arranged on one side of the omnidirectional mobile platform 201. The second nozzle 203 is arranged on the omnidirectional mobile platform 201. The omnidirectional mobile platform 201 adjusts the safety distance with the decontamination device 1. The second decontamination pump 202 is connected to the second nozzle 203. The second drying fan is connected to a second blowing pipe. The second nozzle 203 can spray decontamination liquid on the belly of the aircraft. The second blowing pipe can convey dry airflow to the aircraft.

[0034] The decontamination device 1 is arranged on one side of the aircraft towing device 2 .

[0035] When the automatic disinfection system for the entire aircraft of the present invention is working, the aircraft stops on the omnidirectional mobile platform 201, the disinfection device 1 moves back and forth, and the arm-type robot 103 can drive the first nozzle 106 to disinfect different positions of the aircraft fuselage. At the same time, a second nozzle 203 is arranged on the omnidirectional mobile platform 201, and the belly of the aircraft can be disinfected through the second nozzle 203, thereby realizing all-round disinfection of the entire aircraft and improving the efficiency of disinfection of the entire aircraft. In addition, the present invention is provided with a first drying fan 104 and a second drying fan, which can convey dry airflow to the aircraft so as to dry the aircraft after the aircraft is cleaned, disinfected and sterilized, so as to avoid secondary pollution caused by residual water stains.

[0036] Among them, a radar sensor is also provided at the first nozzle 106, and the radar sensor is provided on the arm-type robot 103. The radar sensor can sense the distance between the first nozzle 106 and the aircraft. When the radar sensor determines that the distance between the first nozzle 106 and the aircraft is suitable for the decontamination operation, the first nozzle 106 cleans, disinfects, sterilizes and dries the aircraft to improve the decontamination efficiency. Correspondingly, the omnidirectional mobile platform 201 has a laser radar sensor, and the laser radar sensor can sense the distance between the omnidirectional mobile platform 201 and the decontamination device 1. At the same time, the laser radar sensor can synchronize with the radar sensor at the first nozzle 106 to ensure a safe distance from the aircraft, ensure that the aircraft surface is not mechanically damaged, and improve the decontamination safety factor.

[0037] In this specific embodiment, the first nozzle 106 is a fan-shaped nozzle, so that the first nozzle 106 can perform fan-shaped spraying and disinfection on the aircraft fuselage, expand the spraying surface, and improve work efficiency. In other specific embodiments of the present invention, the air outlets of the first blowing pipe 107 and the second blowing pipe can be set as fan-shaped air outlets to improve the drying efficiency of the aircraft.

[0038] Specifically, the aircraft towing device 2 is also connected to a lifting mechanism 206, which is arranged on both sides of the omnidirectional mobile platform 201. The lifting mechanism 206 can cooperate with the towing wheel 205 to coordinately adjust the position of the aircraft, wherein the lifting mechanism 206 adjusts the height position of the omnidirectional mobile platform 201, and the towing wheel 205 adjusts the horizontal position of the omnidirectional mobile platform 201 to ensure a safe distance between the aircraft and the device, while ensuring that the cleaning range of the device can cover the entire surface of the aircraft. In this specific embodiment, the lifting mechanism 206 is arranged at both ends of the omnidirectional mobile platform 201 to improve the convenience of operation.

[0039] In addition, the automatic disinfection system for the entire aircraft also includes a ramp device 3, which is arranged at an angle. The higher end of the ramp device 3 is connected to the omnidirectional mobile platform 201, and the two ramp devices 3 are respectively connected to the two ends of the omnidirectional mobile platform 201. By using the ramp device 3, the aircraft can smoothly travel to the omnidirectional mobile platform 201. The ramp devices 3 are arranged at both ends of the omnidirectional mobile platform 201 to improve the convenience of operation. The ramp device 3 is detachably connected to the omnidirectional mobile platform 201, which is convenient for disassembly and assembly, and avoids the ramp device 3 affecting the movement of the omnidirectional mobile platform 201.

[0040] In this specific embodiment, the angle between the ramp device 3 and the horizontal plane is 2.5°, the slope is gentle, and the difficulty of climbing is reduced. It should be noted here that the ramp device 3 is welded with square steel and patterned steel, and anti-rust paint is applied on the surface of the ramp device 3 to prevent metal corrosion.

[0041] More specifically, there are multiple second nozzles 203, which are arranged in a rectangular array. The second disinfection pump 202 is connected to the second nozzles 203 through a disinfection pipeline 204. The multiple second nozzles 203 can disinfect different parts of the belly of the aircraft, thereby improving the efficiency of the disinfection work.

[0042] In order to facilitate control, the decontamination device 1 is provided with a first controller, and the rail car 102, the arm-type robot 103, the first drying fan 104, the first decontamination pump 105, and the first nozzle 106 are all connected to the first controller. The arm-type robot 103 is provided with a photoelectric sensor, and the photoelectric sensor is connected to the first controller; the aircraft towing device 2 is provided with a second controller, and the omnidirectional mobile platform 201, the second decontamination pump 202, the second drying fan and the second nozzle 203 are all connected to the second controller. The first control is installed on the rail car 102, and the first control device can plan the movement path for the arm-type robot 103 according to the position of the aircraft surface to be decontaminated. The first control device and the radar sensor collect the distance signal from the aircraft surface through Ethernet communication, and the first control device can issue a decontamination command to control the arm-type robot 103, the first decontamination pump 105, the first drying fan 104 and the rail car 102 to perform corresponding actions. At the same time, the first control device can monitor the distance signal fed back by the radar sensor to ensure the safety of the aircraft. The second control device can control the omnidirectional mobile platform 201. The omnidirectional mobile platform 201 uses SLAM natural navigation combined with inertial navigation for precise positioning. Because the position of the aircraft is deviated and the fuselage of the aircraft is tilted each time it is manually parked, the aircraft is first manually dragged to the designated position on the omnidirectional mobile platform 201. After completion, the second control device sends a positioning function start. The omnidirectional mobile platform 201 uses SLAM natural navigation and inertial navigation based on a laser radar sensor to adjust the position of the aircraft. After the adjustment is completed, according to the disinfection process, the second control device controls the second disinfection pump 202 and the second drying fan to disinfect and dry the belly of the aircraft. In addition, the omnidirectional mobile platform 201 integrates an anti-collision soft rubber strip switch and an obstacle detection sensor for personal and equipment safety protection.

[0043] Furthermore, a drag chain 4 is arranged between the track and the rail car 102, and between the second decontamination pump 202 and the omnidirectional mobile platform 201. During the movement of the rail car 102 and the second decontamination pump 202, the drag chain 4 can ensure the normal transportation of the decontamination liquid, while protecting the safety of the electrical components, thereby ensuring the normal progress of the decontamination work; the tug wheel 205 is a Mecanum wheel, which can rotate 360° and adopts a laser radar sensor for navigation and positioning, and can realize precise positioning in a compact space, and is used for precise positioning of the parking position of the aircraft.

[0044] In addition, in this specific embodiment, the number of the decontamination devices 1 is twelve, and the twelve decontamination devices 1 are evenly distributed on both sides of the omnidirectional mobile platform 201 and work simultaneously to improve the aircraft decontamination efficiency. In actual applications, the number of decontamination devices 1 can be determined according to the aircraft model.

[0045] When the automatic disinfection system for the entire aircraft of the present invention is working, the aircraft stops on the omnidirectional mobile platform 201, the omnidirectional mobile platform 201 can assist the aircraft in precise positioning, the rail car 102 reciprocates, and the arm-type robot 103 arranged on the rail car 102 can drive the first nozzle 106 to disinfect different positions of the aircraft fuselage. At the same time, the second nozzle 203 is arranged on the omnidirectional mobile platform 201, and the belly of the aircraft can be disinfected through the second nozzle 203, and the entire aircraft can be disinfected in all directions, thereby improving the efficiency of the disinfection of the entire aircraft. In addition, the present invention is provided with a first drying fan 104 and a second drying fan, which can convey dry airflow to the aircraft so as to dry the aircraft after the aircraft is cleaned, disinfected and sterilized, so as to avoid secondary pollution caused by residual water stains.

[0046] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
