Description
Technical Field
[0001] This invention relates to the field of cleaning equipment technology, specifically a cleaning robot for high-rise glass curtain walls. Background Technology
[0002] A glass curtain wall is a non-load-bearing building envelope structure, using glass as the main panel material, combined with a metal frame, sealing materials, etc. It is widely used in modern high-rise buildings and public buildings. It is fixed to the main building structure through connectors and only bears its own weight, wind load, seismic action, etc., without bearing the load of the main building structure. High-rise glass curtain wall cleaning is a professional engineering operation that carries out high-altitude special cleaning of the glass curtain wall of the building facade. It removes pollutants such as dust, scale, oil stains, bird droppings, and dirt from the surface of the glass curtain wall, ultimately maintaining the transparency and beauty of the curtain wall, ensuring lighting performance, and extending the service life of the curtain wall.
[0003] When existing cleaning robots clean the exterior surface of glass curtain walls, the wastewater they produce flows down naturally, causing the wastewater, mud, and stains that drip from the height to splash onto pedestrians on the ground. This results in pedestrians getting their clothes dirty and their bodies splashed with wastewater. At the same time, the wastewater forms slippery puddles on the ground, which can easily cause pedestrians to slip and fall, and can also lead to pedestrian complaints and public safety disputes. Summary of the Invention
[0004] The purpose of this invention is to address the problem that existing cleaning robots, when cleaning the exterior surfaces of glass curtain walls, generate wastewater that naturally flows downwards, causing wastewater, along with mud and dirt, to drip onto pedestrians on the ground, resulting in soiled clothing, splashing of wastewater onto their bodies, and slippery puddles that easily cause pedestrians to slip and fall, leading to complaints and public safety disputes. This invention provides a cleaning robot for high-rise glass curtain walls.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a cleaning robot for high-rise glass curtain walls, comprising: a positioning component fixedly connected to the inner side of the glass curtain wall, one end of the positioning component being provided with a cleaning component for cleaning the glass curtain wall, and the cleaning component being provided on the outer side of the glass curtain wall, the cleaning component being provided with an injection component for providing cleaning fluid and a collection component for collecting wastewater, one end of the injection component being provided at the top of the high-rise building where the glass curtain wall is located, and one end of the collection component being provided on the ground; The wastewater collection device includes a T-shaped wastewater collection box. During cleaning, the top of the collection box is flush with the bottom of the glass being cleaned, and the top of the collection box extends to the inner bottom of the fixed end of the metal frame that holds the glass, allowing the wastewater to fall naturally into the collection box as it flows down. A guide block with an isosceles triangular cross-section is fixedly connected to the bottom of the inside of the collection box. A drain hole is opened through the bottom of the inside of the collection box. A conical manifold for collecting wastewater is fixedly connected to the bottom of the collection box, and the manifold is positioned directly below the drain hole. A cross-shaped fixing frame is fixedly connected to the inside of the drain hole. A guide rope is fixedly connected to the bottom of the fixing frame. The guide rope passes through the manifold, and the diameter of the through hole on the manifold is larger than that of the guide rope. A wastewater tank is fixedly connected to the bottom of the guide rope. The wastewater tank is located in the ground work area below the glass curtain wall of the high-rise building.
[0006] As a further embodiment of the present invention: the positioning component includes a rectangular mounting frame 1 with an inner side of the glass curtain wall.

A magnetic suction column is fixedly connected to the corner of the rectangular mounting frame 1 facing the glass curtain wall. A magnetic block is embedded in the end face of the magnetic suction column facing the glass curtain wall. When the pneumatic suction cup fixes the mounting frame 1 to the inner side of the glass curtain wall, the protruding part of the mounting frame 1 inserts into the inner side of the fixed end of the metal frame of the glass to be cleaned and abuts against the inner side of the fixed end, so that the cleaning area of the cleaning component connected to the positioning component is precisely aligned with the outer side of the glass to be cleaned.
[0007] As a further embodiment of the present invention: the cleaning component includes a second mounting frame that magnetically attracts a magnetic block at the end face of the magnetic column. A magnetic block is embedded at the corner of the second mounting frame facing the glass curtain wall, and the magnetic block and the magnetic block embedded on the magnetic column have opposite poles. A linear actuator is fixedly connected to the second mounting frame in the vertical direction. The linear actuator mainly includes a motor, a lead screw, a nut, and a moving block. The lead screw and the nut constitute a motion conversion mechanism. After startup, the motor outputs rotational motion, which is converted into linear motion by the lead screw-nut mechanism. The guiding component and the control component work together to ensure smooth and precise motion and realize the efficient conversion of electrical energy into linear driving force. A scraping component is provided on the moving block of the linear actuator. One end of the dirt collection box is fixedly connected to the second mounting frame. The stroke of the linear actuator is greater than the length of each glass panel.
[0008] As a further embodiment of the present invention: the scraping component includes a mounting plate fixedly connected to the moving block of the linear actuator, an extension plate fixedly connected to the side of the mounting plate facing the glass curtain wall, and the mounting plate and the extension plate are distributed in a T-shape, a cleaning brush fixedly connected to the side of the extension plate facing the glass curtain wall, the length of the cleaning brush being consistent with the width of each glass panel, and a flow guide platform with a triangular cross-section fixedly connected to the top of the extension plate, the inclined surface of the triangular flow guide platform facing upward.
[0009] As a further embodiment of the present invention: the liquid injection component includes a clean water tank fixedly connected to the top of a high-rise building and storing cleaning liquid therein, a fixing plate fixedly connected to the top of the clean water tank, a winding motor fixedly connected to the top of the fixing plate, a winding reel fixedly connected to the output end of the winding motor, a pull rope fixedly connected to the winding reel, a cleaning box provided at one end of the pull rope, the cleaning box being fixedly connected to the second mounting frame, and the cleaning box being positioned directly above the guide platform.
[0010] As a further embodiment of the present invention: a drain cylinder is fixedly connected to one end of the clean water tank, and one end of the drain cylinder penetrates through the clean water tank. A pump is fixedly connected to the bottom of the inside of the clean water tank. The output end of the pump is connected to the drain cylinder, so that the cleaning liquid in the clean water tank is pumped into the drain cylinder by the pump. One end of the pull rope penetrates through the outer circumference of the drain cylinder and is fixedly connected to the cleaning box. The diameter of the through hole through which the pull rope passes through the drain cylinder is larger than that of the pull rope, so that the cleaning liquid in the drain cylinder falls down along the pull rope into the cleaning box.
[0011] As a further embodiment of the present invention: a drain hole is provided through the bottom of the cleaning box, and a conical plug is slidably inserted into the drain hole. The plug is larger at the top and smaller at the bottom, and the diameter of the top end is the same as the inner diameter of the drain hole. A circular sealing plate is fixedly connected to the top end of the plug, and the diameter of the sealing plate is larger than the inner diameter of the drain hole.
[0012] As a further embodiment of the present invention: a limiting plate is fixedly connected to the bottom end of the block, the length of the limiting plate being greater than the inner diameter of the drain hole. When the linear actuator drives the scraper to move upward, the top inclined surface of the guide platform abuts against the limiting plate, pushing the block upward and creating a gap between the block and the drain hole. This allows the cleaning fluid in the cleaning box to fall and contact the top inclined surface of the guide platform, and under the guidance of the top inclined surface of the guide platform, enter the cleaning brush area, so that the cleaning brush applies the cleaning fluid to the glass curtain wall.
[0013] Compared with the prior art, the beneficial effects of the present invention are: 1.

The installation and disassembly are convenient, adapting to the positioning requirements of glass curtain walls of different specifications, and improving the adaptability and accuracy of the operation. 2. In this invention, the magnetic linkage between the cleaning component and the positioning component is achieved through the mounting frame of the cleaning component. The linear driver provides a stable linear driving force, which drives the scraping component to complete the full-coverage cleaning of the glass. The size of the cleaning brush is adapted to the width of the glass, ensuring that the horizontal area of the glass can be covered in one swipe. The guide platform guides the cleaning liquid to be evenly distributed. Automated reciprocating cleaning replaces manual operation, greatly improving cleaning efficiency, while avoiding the safety risks of manual high-altitude operation. 3. In this invention, the cleaning fluid is centrally stored in the clear water tank of the injection unit, the pump and the drain cylinder ensure stable delivery of the cleaning fluid, the pull rope moves synchronously with the cleaning unit to achieve flexible adaptation of the cleaning fluid delivery path, and the linkage structure of the guide platform and the limiting plate enables the cleaning fluid to be automatically dispensed on demand and automatically cut off when there is no cleaning operation to avoid waste of cleaning fluid, while ensuring that the cleaning fluid is evenly applied to the cleaning brush area to improve the glass cleaning effect; 4. In this invention, the T-shaped sewage collection box of the sewage collection component is attached to the bottom of the glass and the inner side of the metal frame to achieve seamless collection of clean sewage, preventing sewage from dripping down from the source.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.
[0018] Reference Figures 1 to 2 In this embodiment of the invention, a cleaning robot for high-rise glass curtain walls includes: a positioning component 1 fixedly connected to the inner side of the glass curtain wall; a cleaning component 2 for cleaning the glass curtain wall is provided at one end of the positioning component 1, and the cleaning component 2 is provided on the outer side of the glass curtain wall; the cleaning component 2 is provided with an injection component 3 for providing cleaning fluid and a collection component 4 for collecting wastewater; one end of the injection component 3 is provided at the top of the high-rise building where the glass curtain wall is located, and one end of the collection component 4 is provided on the ground.
[0019] Reference Figure 3 The positioning component 1 includes a rectangular mounting frame 11 with an inner side of the glass curtain wall. The mounting frame 11 has a convex cross-section, with the protruding part located on the inner side of the mounting frame 11. A pneumatic suction cup 12 is fixedly connected to the side of the mounting frame 11 facing the glass curtain wall. A magnetic suction column 13 is fixedly connected to the corner of the rectangular mounting frame 11 facing the glass curtain wall. A magnetic block is embedded in the end face of the magnetic suction column 13 facing the glass curtain wall. When the pneumatic suction cup 12 fixes the mounting frame 11 to the inner side of the glass curtain wall, the protruding part of the mounting frame 11 inserts into the inner side of the fixed end of the metal frame of the glass to be cleaned and abuts against the inner side of the fixed end, so that the cleaning area of the cleaning component 2 connected to the positioning component 1 is precisely aligned with the outer side of the glass to be cleaned.
[0020] The above solution is adopted: the mounting frame 11 of the positioning component 1 is fixed by negative pressure with the pneumatic suction cup 12 to achieve stable installation of the cleaning robot on the inside of the glass curtain wall. With the magnetic adsorption of the magnetic column 13, the cleaning component 2 is precisely aligned with the outside of the glass to be cleaned, avoiding the cleaning area from shifting and ensuring the accuracy and stability of the cleaning operation.
[0021] Reference Figures 4 to 5 The cleaning component 2 includes a second mounting frame 21 that magnetically attracts a magnetic block to the end face of the magnetic column 13. A magnetic block is embedded at the corner of the mounting frame 21 facing the glass curtain wall, and the corresponding surfaces of this magnetic block and the magnetic block embedded on the magnetic column 13 are opposite poles. A linear actuator 22 is vertically fixedly connected to the mounting frame 21. The linear actuator 22 mainly includes a motor, a lead screw, a nut, and a moving block. The lead screw and nut constitute a motion conversion mechanism. After startup, the motor outputs rotational motion, which is converted into linear motion through the lead screw-nut mechanism. The guiding component and the control component work together to ensure smooth and precise motion, achieving efficient conversion of electrical energy into linear driving force. A scraper 23 is provided on the moving block 22. One end of the dirt collection box 41 is fixedly connected to the second mounting frame 21. The stroke of the linear actuator 22 is greater than the length of each glass piece. The scraper 23 includes a mounting plate 231 fixedly connected to the moving block of the linear actuator 22. An extension plate 232 is fixedly connected to the side of the mounting plate 231 facing the glass curtain wall. The mounting plate 231 and the extension plate 232 are distributed in a T-shape. A cleaning brush 233 is fixedly connected to the side of the extension plate 232 facing the glass curtain wall. The length of the cleaning brush 233 is the same as the width of each glass piece. A flow guide platform 234 with a triangular cross section is fixedly connected to the top of the extension plate 232. The inclined surface of the triangular flow guide platform 234 faces upward.
[0022] The above solution is adopted: the linear driver 22 of the cleaning component 2 drives the scraper 23 to make vertical reciprocating linear motion. Combined with the size design of the cleaning brush 233 that is adapted to the width of a single glass panel, the full coverage cleaning of a single glass panel is achieved. Relying on the inclined structure of the guide platform 234, the cleaning liquid is guided to flow evenly to the cleaning brush 233, thereby improving the cleaning effect and work efficiency of the glass curtain wall.
[0023] Reference Figures 6 to 8The liquid injection component 3 includes a clean water tank 31 fixedly connected to the top of a high-rise building and containing cleaning fluid. A fixing plate 32 is fixedly connected to the top of the clean water tank 31, and a winding motor 33 is fixedly connected to the top of the fixing plate 32. A winding reel 34 is fixedly connected to the output end of the winding motor 33, and a pull rope 35 is fixedly connected to the winding reel 34. A cleaning box 36 is provided at one end of the pull rope 35. The cleaning box 36 is fixedly connected to the mounting frame 21 and is positioned directly above the guide platform 234. A drain cylinder 311 is fixedly connected to one end of a clean water tank 31, and one end of the drain cylinder 311 passes through the clean water tank 31. A pump is fixedly connected to the bottom of the clean water tank 31, and the output end of the pump is connected to the drain cylinder 311, so that the cleaning liquid in the clean water tank 31 is pumped into the drain cylinder 311 by the pump. One end of a pull rope 35 passes through the outer surface of the drain cylinder 311 and is fixedly connected to the cleaning box 36. The diameter of the through hole of the pull rope 35 through the drain cylinder 311 is larger than that of the pull rope 35, so that the cleaning liquid in the drain cylinder 311 is drawn into the drain cylinder 311. The cleaning solution falls along the pull cord 35 into the cleaning box 36. A drain hole 361 is provided at the bottom of the cleaning box 36. A conical plug 362 is slidably inserted into the drain hole 361, with the plug 362 being larger at the top and smaller at the bottom. The diameter of the top of the plug 362 is the same as the inner diameter of the drain hole 361. A circular sealing plate 263 is fixedly connected to the top of the plug 362, and the diameter of the sealing plate 263 is larger than the inner diameter of the drain hole 361. A limiting plate 364 is fixedly connected to the bottom of the plug 362, and the length of the limiting plate 364 is greater than... As the linear actuator 22 drives the scraper 23 to move upward, the top inclined surface of the guide platform 234 abuts against the limiting plate 364, pushing the block 362 upward, creating a gap between the block 362 and the drain hole 361. This allows the cleaning fluid in the cleaning box 36 to fall and contact the top inclined surface of the guide platform 234, and under the guidance of the top inclined surface of the guide platform 234, enter the cleaning brush 233 area, so that the cleaning brush 233 can apply the cleaning fluid to the glass curtain wall.
[0024] The above solution is adopted: the cleaning fluid is stored in the clean water tank 31 of the injection component 3, and the cleaning fluid is directionally transported by the pump and the drain cylinder 311. The pull rope 35 moves synchronously with the cleaning component 2, and the cleaning fluid is automatically discharged by the contact linkage between the guide table 234 and the limit plate 364, so as to avoid waste of cleaning fluid and achieve precise linkage between cleaning fluid supply and cleaning operation.
[0025] Reference Figures 9 to 12The wastewater collection component 4 includes a wastewater collection box 41 for collecting wastewater. The wastewater collection box 41 is T-shaped, and during cleaning, the top of the wastewater collection box 41 is flush with the bottom of the glass piece being cleaned. The top of the wastewater collection box 41 facing the glass extends to the bottom inner side of the fixed end of the metal frame that fixes the glass piece, so that the wastewater naturally falls into the wastewater collection box 41 as it flows down. A guide block 411 with an isosceles triangular cross-section is fixedly connected to the bottom inside the wastewater collection box 41. A drain hole 412 is opened through the bottom inside the wastewater collection box 41. The bottom of the box 41 is fixedly connected to a conical manifold 413 for collecting sewage, and the manifold 413 is located directly below the drain hole 412. A cross-shaped fixing bracket 414 is fixedly connected to the inside of the drain hole 412. A guide rope 42 is fixedly connected to the bottom of the fixing bracket 414. The guide rope 42 passes through the manifold 413, and the diameter of the through hole on the manifold 413 is larger than that of the guide rope 42. A sewage tank 43 is fixedly connected to the bottom of the guide rope 42. The sewage tank 43 is located in the ground operation area below the glass curtain wall of the high-rise building.
[0026] The above solution is adopted: the T-shaped sewage collection box 41 of the sewage collection component 4 is attached to the bottom of the glass and the inner side of the metal frame to realize the full range of collection of clean sewage. The sewage is collected by the guide block 411 and the confluence tube 413. With the help of the guide rope 42, the sewage is directed to the ground sewage tank 43, preventing sewage from flowing down and dripping, eliminating pedestrian safety hazards, and protecting the curtain wall substrate from sewage corrosion.
[0027] The working principle of this invention is as follows: Before operation, it is necessary to confirm that the environment meets the general requirements for no wind or light wind for cleaning high-rise glass curtain walls. Strong winds can have multiple fatal effects on any high-altitude cleaning operation. First, they will change the trajectory of the cleaning liquid and wastewater, causing the liquid to spread and contaminate the cleaned area. Second, they will generate lateral thrust on the cleaning equipment, damaging the fixed stability of the equipment and the curtain wall, and causing the equipment to fall. Third, they will interfere with the balance and operation of the operators (if manual labor is involved), inducing high-altitude fall accidents. Therefore, a no-wind or light-wind environment is the basic prerequisite for ensuring the safety and effectiveness of all high-rise glass curtain wall cleaning operations. Then, the mounting frame 11 of the positioning component 1 is attached to the inner side of the glass curtain wall to be cleaned, and the pneumatic suction cup 12 is activated to generate negative pressure, so that the mounting frame 11 is firmly adsorbed. On the glass surface, simultaneously, the convex protrusion of the mounting frame 11 is precisely embedded inside the metal frame of the glass to be cleaned, achieving mechanical positioning and preventing the positioning component 1 from shifting. At this time, the magnetic block on the end face of the magnetic column 13 is exposed. Then, the winding motor 33 drives the winding reel 34 to rotate, releasing the pull rope 35 wound on the winding reel 34. This causes the cleaning box 36, the cleaning component 2 fixedly connected to the cleaning box 36, and the dirt collection box 41 fixedly installed on the cleaning component 2 to move down until the magnetic block of the mounting frame 21 aligns with the magnetic block embedded on the magnetic column 13. Through the magnetic attraction between the magnetic column 13 and the mounting frame 21, the precise docking of the positioning component 1 and the cleaning component 2 is quickly completed, ensuring that the cleaning area of the cleaning component 2 is completely aligned with the glass to be cleaned, laying a precise foundation for subsequent cleaning operations. First, the pump of the injection unit 3 is started, and the cleaning fluid in the clean water tank 31 is drawn into the drain cylinder 311. Because the diameter of the through hole of the drain cylinder 311 is larger than that of the pull rope 35, the cleaning fluid falls along the rope due to its own gravity and the adhesion tension on the surface of the pull rope 35. At this time, thanks to the windless environment requirements common to high-rise cleaning, there is no lateral wind interference, and the cleaning fluid will not be blown away from the pull rope 35 by the wind. It can flow stably into the cleaning box 36 fixedly connected to the installation frame 21 for storage. Then, the linear actuator 22 of the cleaning unit 2 is started. The moving block on the linear actuator 22 drives the scraper 23 to move upward synchronously. During this process, the inclined surface of the top of the guide platform 234 of the scraper 23 gradually abuts against the limiting plate 364 of the cleaning box 36, pushing the conical block 362 to move upward, so that the block 36 A gap is created between the cleaning box 36 and the drain hole 361. The cleaning liquid in the cleaning box 36 falls through the drain hole 361 onto the inclined surface of the guide platform 234, and flows evenly along the inclined surface to the cleaning brush 233. The cleaning brush 233 moves upward with the scraper 23, evenly applying the cleaning liquid to the glass curtain wall surface and scraping simultaneously to remove stains, dust and other contaminants from the glass. Finally, the wastewater generated during cleaning flows naturally down the glass surface. Because the top of the T-shaped wastewater collection box 41 of the collection component 4 is flush with the bottom of the glass and extends to the inner bottom of the metal frame fixing end, it can fully collect the flowing wastewater. After the wastewater enters the wastewater collection box 41, it is guided by the inclined surface of the isosceles triangular guide block 411 and converges into the drain hole 412. After being collected by the conical manifold 413, it falls down along the guide rope 42 at the bottom of the fixing frame 414.Similarly, relying on the windless environment common in high-rise cleaning, the wastewater flows steadily down using its own gravity and the adhesion tension of the guide rope 42, preventing it from being blown away by the wind. It ultimately flows precisely into the wastewater tank 43 on the ground for centralized collection, avoiding safety hazards caused by wastewater dripping at the source. This also meets the environmental protection requirements of general operating procedures. When cleaning a single glass panel is finished, the linear actuator 22 reverses its direction, causing the scraper 23 to move vertically downwards. The guide platform 234 separates from the limit plate 364, and the conical block 362 falls under its own weight, resealing the drain hole 361. The cleaning fluid supply stops. During the downward movement, the cleaning brush 233 performs a secondary scraping of the glass surface to remove residual water stains, completing the cleaning of the single glass panel. If further cleaning is needed... To clean other glass panes, release the negative pressure of the pneumatic suction cup 12, move the positioning component 1 to the inside of the next glass pane, and repeat the entire process. This allows for precise cleaning of each pane of high-rise glass curtain wall without requiring manual high-altitude work, adhering to general safety regulations for high-rise cleaning while further improving operational efficiency and stability. The convex structure of the mounting frame 11 of the positioning component 1 allows for precise embedding into the glass's metal frame for positioning and limiting. Combined with the negative pressure of the pneumatic suction cup 12, this ensures stable installation of the robot inside the glass. The magnetic adsorption structure of the magnetic column 13 quickly connects with the cleaning component 2, ensuring precise alignment between the cleaning area of the cleaning component 2 and the glass to be cleaned, preventing cleaning misalignment. Installation and disassembly are convenient. To adapt to the positioning requirements of glass curtain walls of different specifications and improve operational adaptability and accuracy, the cleaning component 2 is magnetically linked with the positioning component 1 through the mounting frame 21. The linear actuator 22 provides stable linear driving force, driving the scraper 23 to complete full-coverage cleaning of the glass. The cleaning brush 233 is sized to match the width of the glass, ensuring that the horizontal area of the glass can be covered with one swipe. The guide platform 234 guides the cleaning fluid to be evenly distributed. Automated reciprocating cleaning replaces manual operation, greatly improving cleaning efficiency while avoiding the safety risks of manual high-altitude operations. The cleaning fluid is centrally stored through the clean water tank 31 of the liquid injection component 3. The pump and drain cylinder 311 ensure stable delivery of the cleaning fluid. The pull rope 35 moves synchronously with the cleaning component 2 to achieve cleaning... The flexible adaptation of the cleaning fluid delivery path and the linkage structure between the guide platform 234 and the limiting plate 364 enable automatic on-demand dispensing of cleaning fluid and automatic fluid cut-off when no cleaning work is being performed, avoiding waste of cleaning fluid. Simultaneously, it ensures that the cleaning fluid is evenly applied to the cleaning brush 233 area, improving the glass cleaning effect. The T-shaped collection box 41 of the collection component 4 fits snugly against the bottom of the glass and the inner side of the metal frame, achieving seamless collection of cleaning wastewater and preventing wastewater from dripping downwards at the source. The guide block 411 and the confluence tube 413 enable rapid collection of wastewater, and the guide rope 42 directs the wastewater to the ground wastewater tank 43, preventing wastewater from corroding the curtain wall metal frame and sealing strips, eliminating safety hazards such as wastewater splashing onto pedestrians and slippery ground, and achieving centralized wastewater collection and environmentally friendly treatment.
