Description

Technical Field

[0001] This invention relates to the field of cleaning robot technology, and in particular to a high-rise building exterior wall cleaning robot. Background Technology

[0002] With the rapid advancement of urbanization, the number of high-rise buildings and glass curtain wall buildings in cities has increased dramatically. The exterior walls of these buildings are exposed to the outdoor environment for a long time, making them prone to accumulating dirt such as dust, oil, catkins, and water stains. This not only affects the overall aesthetics of the building, but also causes long-term accumulation of dirt to corrode the exterior wall material, reduce the light transmittance of the curtain wall, and shorten its service life. Therefore, routine cleaning and maintenance of the exterior walls of high-rise buildings has become an important part of building operation and maintenance.

[0003] Currently, most high-rise building exterior cleaning operations rely on traditional manual rope-slung work, commonly known in the industry as the "spider-man" work mode. Even the few automated cleaning equipment available have numerous technical shortcomings. Manual high-altitude work falls into the category of high-risk operations, with frequent safety hazards such as falls from heights, falling objects, and swaying in strong winds. The safety of these operations is extremely poor. Furthermore, manual cleaning is inefficient, costly, and prone to uneven wiping, leading to blind spots, residue, and inconsistent cleaning quality.

[0004] Existing exterior wall cleaning robots on the market have relatively simple structural designs. Their core cleaning component, the brush roller assembly, mostly only has a single self-rotation function. The roller's position is fixed, and the operation mode is monotonous and rigid. In actual high-altitude cleaning operations, the roller can only rotate and brush in a fixed position. The robot relies solely on its overall movement to complete large-area cleaning of the wall. It cannot perform staggered or reciprocating fine-tuning cleaning of areas such as exterior wall seams, uneven corners, and areas with stubborn stains. The static fixed-point rotation cleaning method easily leads to incomplete rinsing of stains, leaving many cleaning blind spots and poor overall cleaning cleanliness. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a high-rise building exterior wall cleaning robot.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-rise building exterior wall cleaning robot includes a cleaning machine body. A walking device and a wind pressure adsorption device are respectively installed at the bottom of the cleaning machine body. A cleaning device is installed on the front side of the cleaning machine body. The cleaning device includes a cleaning tank shell located on the front side of the cleaning machine body with an open bottom. A brush roller assembly and a water-absorbing roller assembly are arranged at intervals in the front and back of the cleaning tank shell. Both the brush roller assembly and the water-absorbing roller assembly can rotate and slide left and right along the axial direction. A rotary transmission mechanism and a transverse transmission mechanism are also respectively installed in the cleaning tank shell. A power device connected to both the rotary transmission mechanism and the transverse transmission mechanism is installed in the cleaning machine body. The power device provides power to drive the brush roller assembly and the water-absorbing roller assembly to rotate through the rotary transmission mechanism and to drive them to slide left and right along the axial direction through the transverse transmission mechanism.

[0008] In some embodiments, a sliding frame is slidable left and right inside the cleaning tank shell. The brush roller assembly and the water-absorbing roller assembly are both rotatably mounted on the sliding frame. The brush roller assembly includes a first central shaft, a first fixed shaft that slides axially on the first central shaft, and a brush disposed on the first fixed shaft. Both ends of the first fixed shaft are rotatably mounted on the sliding frame. The water-absorbing roller assembly includes a second central shaft, a second fixed shaft that slides axially on the second central shaft, and water-absorbing cotton disposed on the second fixed shaft. Both ends of the second fixed shaft are rotatably mounted on the sliding frame. Both ends of the first central shaft and the second central shaft are rotatably mounted on the cleaning tank shell.

[0009] In some embodiments, guide rods are provided at intervals on both the left and right sides of the sliding frame, and the guide rods on both sides are movably inserted through the side wall of the cleaning tank shell.

[0010] In some embodiments, the power unit includes a motor disposed within the cleaning machine body, the output shaft of the motor extending into the cleaning tank housing and provided with a drive bevel gear, the drive bevel gear being connected to the rotary transmission mechanism and the transverse transmission mechanism respectively.

[0011] In some embodiments, the rotary transmission mechanism includes a first transmission shaft rotatably disposed within the cleaning tank housing, a first bevel gear meshing with the drive bevel gear at one end of the first transmission shaft, a first transmission wheel at the other end, a second transmission wheel and a third transmission wheel respectively disposed at both ends of the second central shaft, a fourth transmission wheel disposed at one end of the first central shaft, a first transmission belt connected and sleeved between the first transmission wheel and the second transmission wheel, and a second transmission belt connected and sleeved between the third transmission wheel and the fourth transmission wheel.

[0012] In some embodiments, the transverse transmission mechanism includes a second transmission shaft rotatably disposed within the cleaning tank housing, a second bevel gear meshing with the first bevel gear is provided at one end of the second transmission shaft, a disc is provided at the other end, an eccentric rod is provided on the disc, a vertical slide groove is provided on the sliding frame, and the eccentric rod is disposed within the vertical slide groove.

[0013] In some embodiments, a water tank is further provided in the cleaning machine body, and a water outlet pipe is connected to one side of the water tank via a water pump. One end of the water outlet pipe is connected to a horizontal pipe, which is located on the cleaning tank shell and connected to a plurality of water spray pipes. Each of the water spray pipes extends into the cleaning tank shell and faces the front side of the brush roller assembly.

[0014] In some embodiments, a scraper mounting bracket is provided on the rear side of the cleaning machine body, and a scraper blade is provided on the rear side of the scraper mounting bracket.

[0015] In some embodiments, a mounting bracket is also provided on the main body of the cleaning machine, and a traction rope is provided on the mounting bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This device has brush roller assemblies and water absorption roller assemblies spaced at the front and back inside the cleaning tank. The two sets of rollers can be driven to rotate autonomously by a rotary transmission mechanism to complete the basic work of brushing wall stains and absorbing sewage. At the same time, the two sets of rollers can be driven to slide left and right along the axis by a transverse transmission mechanism. The combination of dual motion modes breaks the limitations of traditional cleaning equipment with fixed rollers and cleaning by moving the machine body alone. It can perform reciprocating fine cleaning on the corners, gaps, uneven areas and stubborn stains of the exterior walls of buildings, effectively eliminating cleaning blind spots and greatly improving the overall cleaning uniformity and cleaning quality of the exterior walls.

[0018] 2. This device provides power to the rotary transmission mechanism and the transverse transmission mechanism simultaneously through a single power unit, realizing the synchronized operation of brush roller washing, water absorption roller water absorption, and roller body lateral fine adjustment. There is no need for separate operations in each step, making the operation process more continuous and efficient. At the same time, the layout design of the brush roller washing in front and the water absorption roller absorbing water behind immediately can quickly absorb residual sewage on the wall after washing away stains, avoiding the formation of water stains and watermarks by the drying of sewage residue, eliminating secondary pollution of the wall surface, and completing the entire washing and cleaning process in one operation, significantly improving the overall cleaning efficiency.

[0024] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0025] like Figures 1-5 The illustrated high-rise building exterior wall cleaning robot includes a cleaning machine body 1. A walking device 2 and a wind pressure adsorption device 3 are respectively installed at the bottom of the cleaning machine body 1. A cleaning device is installed on the front side of the cleaning machine body 1. The cleaning device includes a cleaning tank 4 located on the front side of the cleaning machine body 1 with an open bottom. A brush roller assembly 5 and a water-absorbing roller assembly 6 are arranged at intervals in front and back within the cleaning tank 4. Both the brush roller assembly 5 and the water-absorbing roller assembly 6 can rotate and slide left and right along the axial direction. A rotary transmission mechanism and a transverse transmission mechanism are also respectively installed within the cleaning tank 4. A power device connected to both the rotary transmission mechanism and the transverse transmission mechanism is installed within the cleaning machine body 1. The power device provides power to drive the brush roller assembly 5 and the water-absorbing roller assembly 6 to rotate via the rotary transmission mechanism and to drive them to slide left and right along the axial direction via the transverse transmission mechanism.

[0026] During operation, this high-rise building exterior wall cleaning robot relies on a walking device 2 and a wind pressure adsorption device 3 located at the bottom of the cleaning machine body 1 to complete the machine's movement and fixation. Both the walking device 2 and the wind pressure adsorption device 3 are existing technologies. The equipment moves and moves on the surface of the high-rise building exterior wall through the walking device 2, while the wind pressure adsorption device 3 generates negative pressure adsorption force to stably adhere and fix the cleaning machine body 1 to the building facade, ensuring the stability and safety of the high-altitude cleaning operation and providing a reliable working foundation for subsequent cleaning operations.

[0027] The overall cleaning operation is completed by a cleaning device located at the front of the cleaning machine body 1. The cleaning tank shell 4, with its lower opening, covers the outside of the external wall cleaning area, protecting the internal cleaning structure and concentrating the cleaning area to prevent stains and wastewater from overflowing. Inside the cleaning tank shell 4, brush roller assemblies 5 and water absorption roller assemblies 6 are arranged at intervals, forming a continuous operation structure of brushing first and then absorbing water.

[0028] During operation, the power unit built into the main body 1 of the cleaning machine serves as the sole power source, simultaneously providing operating power to the rotary transmission mechanism and the transverse transmission mechanism inside the cleaning tank 4. The rotary transmission mechanism, upon receiving power, drives the brush roller assembly 5 and the water-absorbing roller assembly 6 to continuously rotate. The high-speed rotation of the brush roller assembly 5 frictionally scrubs away dust, oil, and stubborn dirt from the exterior wall surface, completing the wall cleaning operation. Then, the rear-mounted water-absorbing roller assembly 6 absorbs residual wastewater from the wall surface, achieving water purification of the wall.

[0029] Simultaneously, the transverse transmission mechanism receives power from the power unit, driving the brush roller assembly 5 and the water-absorbing roller assembly 6, which have completed their rotation, to slide left and right along their own axis. Through the combined motion of roller rotation cleaning and axial transverse movement, the traditional single-point rotation operation mode is changed, allowing the brush roller assembly 5 and the water-absorbing roller assembly 6 to cover a larger cleaning area. At the same time, it performs fine reciprocating cleaning of exterior wall crevices, corners, and uneven areas, compensating for the blind spots of fixed-point rotation cleaning. Combined with the overall displacement of the equipment's traveling device 2, it completes an all-round, no-dead-angle automated cleaning operation of the high-rise building's exterior walls.

[0030] Furthermore, a sliding frame 21 is slidably mounted on the left and right sides inside the cleaning tank shell 4. The brush roller assembly 5 and the water-absorbing roller assembly 6 are both rotatably mounted on the sliding frame 21. The brush roller assembly 5 includes a first central shaft 22, a first fixed shaft 23 that slides axially on the first central shaft 22, and a brush 24 disposed on the first fixed shaft 23. Both ends of the first fixed shaft 23 are rotatably mounted on the sliding frame 21. The water-absorbing roller assembly 6 includes a second central shaft 25, a second fixed shaft 26 that slides axially on the second central shaft 25, and water-absorbing cotton 27 disposed on the second fixed shaft 26. Both ends of the second fixed shaft 26 are rotatably mounted on the sliding frame 21. Both ends of the first central shaft 22 and the second central shaft 25 are rotatably mounted on the cleaning tank shell 4. Guide rods 31 are provided at intervals on both sides of the sliding frame 21. The guide rods 31 on both sides are movably inserted through the side wall of the cleaning tank shell 4.

[0031] The synchronous axial lateral movement of the brush roller assembly 5 and the water absorption roller assembly 6 is achieved by the overall sliding of the sliding frame 21. The brush roller assembly 5 adopts a split sliding structure. The two ends of the first central shaft 22 are fixedly and rotatably mounted on the cleaning tank shell 4, maintaining a fixed axial position. The first fixed shaft 23 can slide left and right along the first central shaft 22. The brush 24 is fixedly mounted on the first fixed shaft 23, and the two ends of the first fixed shaft 23 are rotatably mounted on the sliding frame 21. When the sliding frame 21 slides left and right, it can drive the first fixed shaft 23 and the brush 24 to generate axial sliding displacement relative to the first central shaft 22. At the same time, the first fixed shaft 23 can rotate autonomously relative to the sliding frame 21, realizing the self-rotating brushing operation of the brush 24.

[0032] The corresponding absorbent roller assembly 6 adopts the same split sliding fit structure. The two ends of the second central shaft 25 are rotatably and fixedly installed on the cleaning tank shell 4 and remain stationary. The second fixed shaft 26 can slide left and right along the axial direction of the second central shaft 25. The absorbent cotton 27 is assembled on the surface of the second fixed shaft 26, and the two ends of the second fixed shaft 26 are rotatably installed on the sliding frame 21. During the sliding process of the sliding frame 21, the second fixed shaft 26 and the absorbent cotton 27 are moved axially laterally. At the same time, the second fixed shaft 26 can rotate relative to the sliding frame 21 to complete the adsorption of residual sewage on the wall.

[0033] Guide rods 31 are arranged at intervals on both sides of the sliding frame 21. Both guide rods 31 are movably inserted through the side wall of the cleaning tank shell 4. Through the sliding cooperation between the guide rods 31 and the side wall of the cleaning tank shell 4, the left and right lateral movement of the sliding frame 21 is precisely guided and limited. This ensures that the axial sliding process of the sliding frame 21, the brush roller assembly 5 and the water absorption roller assembly 6 is smooth, without deviation or jamming. It effectively improves the accuracy of the roller lateral movement adjustment and the stability of operation, and makes the composite rotation and lateral movement of the brush 24 and the water absorption cotton 27 more regular and reliable, ensuring the effect of fine cleaning of the exterior wall.

[0034] The power output and dual-mode transmission operation of this equipment are completed by the power unit, rotary transmission mechanism and transverse transmission mechanism working together. The whole system achieves synchronous linkage operation of roller self-rotation cleaning and axial transverse adjustment through a single power source, with high structural transmission coordination and strong operation synchronization.

[0035] The power for all cleaning actions of the machine is provided by the motor 41 located inside the main body 1 of the cleaning machine. The output shaft of the motor 41 extends into the cleaning chamber 4 and is fixedly mounted with the drive bevel gear 42.

[0036] The rotary transmission mechanism is used to achieve synchronous rotation of the brush roller assembly 5 and the water absorption roller assembly 6. The specific transmission process is as follows: A first transmission shaft 51 is rotatably installed inside the cleaning tank 4. A first bevel gear 52 is fixedly mounted at one end of the first transmission shaft 51. The first bevel gear 52 meshes with a driving bevel gear 42. When the driving bevel gear 42 rotates, it drives the first bevel gear 52 to rotate synchronously, causing the first transmission shaft 51 to rotate accordingly. A first transmission wheel 53 is fixedly mounted at the other end of the first transmission shaft 51. A second transmission wheel 54 and a third transmission wheel 55 are fixedly mounted at both ends of the second central shaft 25, respectively. A fourth transmission wheel 56 is fixedly mounted at one end of the first central shaft 22. A first transmission belt 57 is sleeved between the first transmission wheel 53 and the second transmission wheel 54, forming the water absorption roller transmission link; a second transmission belt 58 is sleeved between the third transmission wheel 55 and the fourth transmission wheel 56, forming the brush roller linkage transmission link. Power is transmitted to the second drive wheel 54 via the first drive shaft 51, the first drive wheel 53, and the first drive belt 57, driving the second central shaft 25 to rotate as a whole. This causes the second fixed shaft 26 and the absorbent cotton 27 on its surface to rotate at high speed, absorbing the wastewater after the wall is washed. At the same time, during the rotation of the second central shaft 25, the third drive wheel 55 and the second drive belt 58 drive the fourth drive wheel 56 to rotate synchronously with the first central shaft 22, causing the first fixed shaft 23 and the brush 24 on its surface to rotate at high speed. This allows for the rotational friction and brushing of dust, stubborn stains, and grime on the exterior wall surface, achieving synchronous, unidirectional, and synchronous rotation of the brush roller assembly 5 and the absorbent roller assembly 6.

[0037] The transverse transmission mechanism is used to realize the reciprocating sliding of the brush roller assembly 5 and the water absorption roller assembly 6 along the left and right axes, forming a compound cleaning motion with the rotational action. The specific transmission process is as follows: A second transmission shaft 61 is rotatably installed inside the cleaning tank shell 4. A second bevel gear 62 is fixedly mounted at one end of the second transmission shaft 61. The second bevel gear 62 meshes with the first bevel gear 52. While the first bevel gear 52 is driven to rotate, it synchronously drives the second bevel gear 62 to rotate, thereby driving the second transmission shaft 61 to rotate continuously. A disc 63 is fixedly mounted at the other end of the second transmission shaft 61. An eccentric rod 64 is eccentrically fixed on the end face of the disc 63. A vertical groove 65 is opened on the sliding frame 21, and the eccentric rod 64 is slidably fitted inside the vertical groove 65. As the disc 63 rotates continuously with the second drive shaft 61, the eccentric rod 64 makes uninterrupted eccentric circular motion with the disc 63. The vertical movement margin of the vertical slide groove 65 is used to offset the vertical displacement component of the eccentric rod 64. At the same time, the horizontal displacement component of the eccentric circular motion is converted into horizontal reciprocating pushing and pulling power, and the sliding frame 21 is continuously pushed and pulled to make reciprocating linear sliding in the left and right directions.

[0038] Since the brush roller assembly 5 and the absorbent roller assembly 6 are rotatably mounted on the sliding frame 21, and the first central shaft 22 and the second central shaft 25 are fixed at both ends to the cleaning tank shell 4 and remain stationary, the first fixed shaft 23 can slide along the first central shaft 22 axially, and the second fixed shaft 26 can slide along the second central shaft 25 axially. Therefore, the reciprocating left and right sliding of the sliding frame 21 can drive the first fixed shaft 23, the second fixed shaft 26, and the corresponding brush 24 and absorbent cotton 27 to slide left and right along the roller body axial direction. At the same time, the guide rods 31, which are spaced back and forth on the left and right sides of the sliding frame 21, are movably inserted through the side wall of the cleaning tank shell 4 to precisely guide and limit the lateral movement of the sliding frame 21, preventing sliding deviation, jamming, and shaking, and ensuring a smooth and regular lateral movement.

[0039] In summary, during operation, the brush 24 and absorbent cotton 27 continuously rotate to complete the basic brushing and water absorption actions. At the same time, the entire machine continuously moves left and right back and forth to sweep and wash. Combined with the overall displacement of the machine's walking device 2, the cleaning coverage area is effectively expanded, eliminating blind spots in the cleaning of gaps, corners, and uneven areas of the exterior wall. This solves the defects of traditional single fixed-point rotation cleaning that is not clean and leaves residual water stains and dirt, achieving full coverage, high precision, and residue-free automated cleaning of the exterior wall surface.

[0040] This high-rise building exterior wall cleaning robot integrates a water tank 71 inside the cleaning machine body 1 as a water storage structure to continuously provide cleaning water for automated exterior wall cleaning operations. One side of the water tank 71 is connected to a water outlet pipe 72 via a water pump. During operation, the water pump provides the power to continuously pump the cleaning water stored inside the water tank 71 into the water outlet pipe 72, thus ensuring a stable water supply.

[0041] The outlet end of the water outlet pipe 72 is connected to a horizontal pipe 73 fixed on the cleaning tank shell 4. The horizontal pipe 73 serves as a water distribution structure, which can evenly distribute the cleaning water transported by the water outlet pipe 72 to each spray structure. Several spray pipes 74 are connected below the horizontal pipe 73. All spray pipes 74 extend into the internal area of ​​the cleaning tank shell 4, and the outlet end of the spray pipes 74 faces the front side of the brush roller assembly 5.

[0042] During the equipment cleaning operation, the water pump continuously delivers water. After passing through the water tank 71, the outlet pipe 72, and the horizontal pipe 73, the water is simultaneously sprayed evenly onto the exterior wall surface in front of the brush roller assembly 5 by multiple spray pipes 74. This wets, softens, and rinses the dust, dried dirt, and stubborn stains on the wall surface in advance. Combined with the subsequent self-rotating brushing operation of the brush roller assembly 5, the adhesion strength of dirt is greatly reduced, the cleaning and stain removal effect of the brush is improved, and problems such as incomplete cleaning, wall wear, and dust flying caused by dry brushing are avoided. At the same time, the wetted wall surface can be quickly absorbed by the water absorption roller assembly 6, effectively improving the overall cleanliness and work efficiency of the exterior wall cleaning.

[0043] See Figures 1-3 As shown, a scraper mounting bracket 81 is installed on the rear side of the cleaning machine body 1. The scraper mounting bracket 81 serves as a fixed load-bearing structure, providing stable mounting support for the scraper blade 82 and ensuring the overall structure of the scraper component is robust and reliable. The scraper blade 82 is fixedly mounted on the rear side of the scraper mounting bracket 81, so that the scraper blade 82 is positioned rearward at the rear of the entire machine's cleaning operation structure, forming a multi-stage cleaning operation layout of front-end water spraying and brushing, mid-end water suction, and rear-end scraping for finishing.

[0044] A mounting bracket 91 is installed on the main body 1 of the cleaning machine. The mounting bracket 91 is a special fixed installation structure that provides a stable mounting point for the traction rope 92, ensuring that the traction structure is firmly assembled and under stable force. The traction rope 92 is installed on the mounting bracket 91, so that the traction rope 92 is reliably connected to the top of the machine.

[0045] During high-altitude exterior wall cleaning operations, the traction rope 92 is reliably connected to the cleaning machine body 1 via the mounting bracket 91, providing auxiliary traction, limiting protection, and fall prevention for the entire machine. Combined with the wind pressure adsorption device 3 and the walking device 2 at the bottom of the equipment, the traction rope 92 effectively distributes the force on the equipment at high altitudes, limiting the swaying and displacement of the equipment in strong winds, improving the overall stability of the machine during high-altitude wall operations. Simultaneously, as a safety protection structure, it prevents accidental detachment and falls, significantly enhancing the safety and reliability of high-altitude exterior wall cleaning operations.
