Based on their intended use, they can be categorized as civil, military, and general aviation aircraft. Civil aircraft further include passenger and cargo aircraft. Modern aircraft utilize advanced materials and technologies, such as composite materials to reduce weight, turbofan engines to improve fuel efficiency, and autopilot systems to enhance safety. Aircraft have significantly reduced the time required for long-distance travel. In the military, aircraft are used for reconnaissance, transportation, and combat operations. With technological advancements, aircraft are evolving towards more environmentally friendly and intelligent features. Various types of dirt and debris accumulated on aircraft surfaces not only affect their appearance but also reduce their surface finish, increase friction, and boost fuel consumption.

Detailed implementation manners

[0029] The present invention will be further described below in conjunction with embodiments.

[0030] Please refer to Figures 1-9The present invention provides an aircraft cleaning device, including a top frame 4, a support rod 5 is fixed on the bottom side of the top frame 4, and the support rod 5 is provided with multiple and symmetrically distributed at the corners of the top frame 4. A servo motor 8 is fixed on the top side of the top frame 4, and a transfer assembly 3 is provided on the top of the top frame 4, which is transmission-connected with the servo motor 8. The transfer assembly 3 is transmission-connected with a washing assembly 2 that can move along the length direction of the top frame 4 and wash and clean the exterior of the aircraft. The washing assembly 2 is provided with a liquid regulating assembly 1 for regulating the sprayed liquid; when in use, the aircraft is dragged to the bottom of the top frame 4 and placed inside the washing assembly 2, the servo motor 8 is started to work, and the servo motor 8 drives the transfer assembly 3 to work, thereby driving the washing assembly 2 to move back and forth along the length direction of the top frame 4 through the transfer assembly 3, so that the washing assembly 2 sprays the cleaning liquid evenly and finely to the outer surface of the aircraft, thereby evenly and fully washing the outer surface of the aircraft, and ensuring that the cleaning liquid covers the outer surface of the aircraft through the reciprocating motion of the washing assembly 2 It covers every area of the aircraft's outer surface, avoiding blind spots or omissions that may be caused by traditional fixed nozzles, and improving the consistency of the cleaning effect. The flushing component 2 continuously sprays cleaning liquid during movement, which can quickly soften and remove dirt, oil stains and pollutants on the aircraft surface, significantly shortening the cleaning time. The uniform and refined spraying method reduces the impact on the aircraft surface coating and structure, avoids damage caused by high-pressure water jets or improper cleaning methods, and extends the service life of the aircraft. The automated cleaning formed by the flushing component 2 and the transfer component 3 effectively reduces dependence on manual operation, reduces labor intensity, and improves the safety and reliability of the cleaning operation. At the same time, it can be adapted to aircraft of different models and sizes, has strong versatility and flexibility, and meets the diverse needs of the aviation maintenance field; the liquid adjustment component 1 can adjust the thickness of the water flow sprayed by the flushing component 2, thereby conveniently adjusting the flushing flow rate of the water flow. The liquid adjustment component 1 can flexibly adjust the thickness and flow rate of the water flow according to the type and degree of dirt on the aircraft surface. For stubborn stains, a coarser, high-speed water flow can be used for strong washing; for sensitive areas or light dirt, it can be switched to a fine water flow and low-speed washing to avoid damaging the aircraft surface. By optimizing the water flow thickness and flow rate, pollutants on the aircraft surface can be removed more efficiently, cleaning time can be reduced, and work efficiency can be improved. High-speed and coarse water flow is suitable for large-area cleaning, while fine water flow can be used for cleaning fine parts.

The design of the liquid adjustment component 1 makes water flow adjustment simple and intuitive, and operators can quickly master it without complex training, thereby improving the convenience and operability of cleaning operations.

[0031] Further, as shown in Figure 1 , Figure 6 and Figure 7 It is worth specifically stating that the flushing assembly 2 includes a flushing frame plate 201 disposed inside the top frame 4 and movable and adjustable along the length direction of the top frame 4. A liquid passage cavity 202 is formed inside the flushing frame plate 201. Liquid spraying holes 203 communicating with the liquid passage cavity 202 are formed on the inner side wall of the flushing frame plate 201. A liquid inlet pipe 204 communicating with the liquid passage cavity 202 is fixed on the outer side wall of the flushing frame plate 201. A plurality of liquid spraying holes 203 are provided and the plurality of liquid spraying holes 203 are equidistantly distributed on the inner side wall of the flushing frame plate 201. During specific operation, the liquid inlet pipe 204 is externally connected to a water pump, and the cleaning liquid is conveyed into the inside of the flushing frame plate 201 through the liquid inlet pipe 204 and uniformly and finely sprayed onto the surface of the aircraft through the plurality of liquid spraying holes 203. Thus, the cleaning liquid is uniformly and finely sprayed onto the outer surface of the aircraft through the reciprocatingly moving flushing frame plate 201, so as to uniformly and fully flush the outer surface of the aircraft. Through the reciprocating movement of the flushing frame plate 201, it is ensured that the cleaning liquid covers every area of the outer surface of the aircraft, avoiding cleaning dead corners or omissions that may be caused by traditional fixed nozzles, improving the consistency of the cleaning effect. The flushing frame plate 201 continuously sprays the cleaning liquid during the movement, which can quickly soften and remove dirt, oil stains and pollutants on the surface of the aircraft, significantly shortening the cleaning time. The uniformly and finely spraying method reduces the impact on the surface coating and structure of the aircraft, avoiding damage caused by high-pressure water columns or improper cleaning methods, prolonging the service life of the aircraft. The formed automatic cleaning effectively reduces the dependence on manual operation, reduces the labor intensity, improves the safety and reliability of the cleaning operation at the same time, and can be adapted to aircraft of different models and sizes, having strong versatility and flexibility, and meeting the diverse needs of the aviation maintenance field.

[0032] Further, as shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 It is worth specifically stating that the adjustment and movement assembly 3 includes a connecting rod 301 fixed on the top side surface of the flushing frame plate 201. A convex support plate 306 is fixed on the top side surface of the top frame 4. Two convex support plates 306 are provided and the two convex support plates 306 are symmetrically distributed. A lead screw 304 is rotatably connected between the two convex support plates 306. The output end of the servo motor 8 is coaxially fixed to one end of the lead screw 304. A lead screw nut 302 in threaded cooperation with the lead screw 304 is fixed on the top end of the connecting rod 301. During specific operation, the output end of the servo motor 8 drives the lead screw 304 to rotate, so as to drive the connecting rod 301 to reciprocate through the cooperation of the lead screw 304 and the lead screw nut 302, and then drive the flushing frame plate 201 to reciprocate synchronously through the connecting rod 301.

[0033] Further, as Figure 5 shown, it is worth specifically stating that a convex rod 303 is fixed on the outer side wall of the lead screw nut 302, and a guide rod 305 arranged along the length direction of the top frame 4 is fixed on the top end of the top frame 4. A guide groove arranged along the length direction of the guide rod 305 and slidably adapted to the convex rod 303 is formed in the guide rod 305. During specific operation, the movement of the flushing frame plate 201 is guided and limited by the cooperation of the convex rod 303 and the guide rod 305 provided, thereby effectively improving the stability and accuracy of the movement of the flushing frame plate 201.

[0034] Further, as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, it is worth specifically stating that the liquid adjusting assembly 1 includes a moving and adjusting plate 106 located inside the flushing frame plate 201 and fittingly sliding with the inner side wall of the flushing frame plate 201. Adjusting through holes 107 are formed on the side surface of the moving and adjusting plate 106. There are multiple adjusting through holes 107, and the multiple adjusting through holes 107 are arranged in one-to-one correspondence with the multiple liquid spraying holes 203. A support plate 102 is fixed on the outer side wall of the flushing frame plate 201, and a nut sleeve 103 is fixed inside the support plate 102. A threaded rod 101 is threadedly connected inside the nut sleeve 103, and one end of the threaded rod 101 is rotatably connected to the outer side wall of the flushing frame plate 201. During specific operation, by rotating the threaded rod 101, the moving and adjusting plate 106 is driven to move and adjust through the cooperation of the threaded rod 101 and the nut sleeve 103, so that the adjusting through holes 107 and the liquid spraying holes 203 are misaligned to different degrees, realizing synchronous adjustment of the flow areas of the multiple liquid spraying holes 203, and the thickness of the water flow sprayed from the liquid spraying holes 203 can be adjusted. Thus, the flushing flow rate of the water flow can be conveniently adjusted, and the thickness and flow rate of the water flow can be flexibly adjusted according to the type and degree of dirt on the aircraft surface. For stubborn stains, a relatively thick high-speed water flow can be used for strong flushing; while for sensitive areas or slight dirt, it can be switched to a thin water flow for low-speed flushing to avoid damaging the aircraft surface. By optimizing the thickness and flow rate of the water flow, the pollutants on the aircraft surface can be removed more efficiently, the cleaning time can be reduced, and the operation efficiency can be improved. The high-speed thick water flow is suitable for large-area cleaning, while the thin water flow can be used for cleaning of fine parts, and the flow rate and pressure of the water flow can be precisely controlled to avoid unnecessary waste. At the same time, during the cleaning process, the water flow can be adjusted according to actual needs to reduce water resource consumption, meeting the requirements of environmental protection and energy conservation. The thin water flow low-speed mode is suitable for cleaning of aircraft surface coatings, sensors and precision components, avoiding physical damage or coating peeling caused by high-pressure water flow, extending the service life of the aircraft, making the water flow adjustment simple and intuitive, and the operator can quickly master it without complex training, improving the convenience and operability of the cleaning operation.

[0035] This solution has the following working process: The output end of the servo motor 8 drives the lead screw 304 to rotate back and forth, so as to drive the connecting rod 301 to move back and forth through the cooperation of the lead screw 304 and the lead screw nut 302. Then, the connecting rod 301 drives the flushing frame plate 201 to move synchronously back and forth. The cleaning liquid is conveyed into the interior of the flushing frame plate 201 through the liquid inlet pipe 204 and evenly and finely sprayed onto the surface of the aircraft through a plurality of liquid spraying holes 203. Thus, the cleaning liquid is evenly and finely sprayed onto the outer surface of the aircraft through the reciprocating flushing frame plate 201, so as to conduct a uniform, sufficient and comprehensive flushing of the outer surface of the aircraft. The reciprocating movement of the flushing frame plate 201 ensures that the cleaning liquid covers every area of the outer surface of the aircraft, avoiding cleaning dead corners or omissions that may be caused by traditional fixed nozzles; By rotating the threaded rod 101, the moving and adjusting plate 106 is driven to move and adjust through the cooperation of the threaded rod 101 and the nut sleeve 103, so that the adjusting through hole 107 and the liquid spraying holes 203 are misaligned to different degrees, realizing the synchronous adjustment of the flow areas of a plurality of liquid spraying holes 203, and the thickness of the water flow sprayed out of the liquid spraying holes 203 can be adjusted. Thus, the flushing flow rate of the water flow can be conveniently adjusted, and the thickness and flow rate of the water flow can be flexibly adjusted according to the type and degree of dirt on the aircraft surface.

[0036] Further, as Figure 8 shown, it is worth specifically explaining that a end head plate 104 is fixed to the end of the threaded rod 101 away from the flushing frame plate 201, and a handle rod 105 is fixed to the side surface of the end head plate 104; During specific work, the threaded rod 101 is driven to rotate by holding the handle rod 105. The force arm of the threaded rod 101 is long, and the operation is labor-saving.

[0037] Further, as Figure 8 shown, it is worth specifically explaining that a rubber sleeve 108 is fitted and sleeved on the surface of the handle rod 105, and the length of the rubber sleeve 108 is set to be equal to the length of the handle rod 105; During specific work, the friction force when holding the handle rod 105 is increased through the provided rubber sleeve 108 to prevent slipping.

[0038] Further, as Figure 1 、 Figure 2 and Figure 3 shown, it is worth specifically explaining that bottom plates 6 are fixed to the bottoms of a plurality of support rods 5, and screw holes 7 are formed in the top side surfaces of the plurality of bottom plates 6; During specific work, the top frame 4 is fixedly installed by installing bolts in the screw holes 7, improving the operation stability of the overall device.

[0039] In summary: By driving the flushing component 2 to reciprocate along the length direction of the top frame 4 through the shifting component 3, the flushing component 2 evenly and finely sprays the cleaning liquid onto the outer surface of the aircraft, thereby comprehensively flushing the outer surface of the aircraft evenly and sufficiently. The reciprocating movement of the flushing component 2 ensures that the cleaning liquid covers every area of the aircraft's outer surface, avoiding cleaning dead corners or omissions that may be caused by traditional fixed nozzles, improving the consistency of the cleaning effect. The flushing component 2 continuously sprays the cleaning liquid during the movement, which can quickly soften and remove dirt, oil stains and pollutants on the aircraft surface, significantly shortening the cleaning time. The evenly and finely spraying method of the cleaning liquid reduces the impact on the aircraft surface coating and structure, avoiding damage caused by high-pressure water jets or improper cleaning methods, and extending the service life of the aircraft. The automated cleaning formed by the cooperation of the flushing component 2 and the shifting component 3 effectively reduces the dependence on manual operations, reduces the labor intensity, and improves the safety and reliability of the cleaning operation. At the same time, it can be adapted to different models and sizes of aircraft, with strong versatility and flexibility, meeting the diverse needs of the aviation maintenance field; by setting the liquid adjustment component 1, the thickness of the water flow sprayed by the flushing component 2 can be adjusted, so that the flushing flow rate of the water flow can be conveniently adjusted. The liquid adjustment component 1 can flexibly adjust the thickness and flow rate of the water flow according to the type and degree of dirt on the aircraft surface. For stubborn stains, a thicker high-speed water flow can be used for strong flushing; for sensitive areas or slight dirt, it can be switched to a thin water flow for low-speed flushing to avoid damaging the aircraft surface. By optimizing the thickness and flow rate of the water flow, the pollutants on the aircraft surface can be removed more efficiently, reducing the cleaning time and improving the operation efficiency. The high-speed thick water flow is suitable for large-area cleaning, while the thin water flow can be used for cleaning fine parts. The liquid adjustment component 1 can accurately control the flow rate and pressure of the water flow, avoiding unnecessary waste. At the same time, during the cleaning process, the water flow can be adjusted according to actual needs, reducing water resource consumption, meeting the requirements of environmental protection and energy conservation. The thin water flow low-speed mode is suitable for cleaning the aircraft surface coating, sensors and precision components, avoiding physical damage or coating peeling caused by high-pressure water flow, and extending the service life of the aircraft.
