Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, and in particular to an intelligent high-altitude exterior wall cleaning device. Background Technology

[0002] With the acceleration of urbanization and economic development, high-rise and even super high-rise buildings have sprung up globally, becoming important symbols of modern cities. These buildings generally use large areas of glass curtain walls or windows as their exterior walls to achieve good lighting, aesthetically pleasing visual effects, and a modern image. However, large glass facades are exposed to the natural environment for extended periods, easily accumulating dust, stains, and rainwater residue, severely impacting the building's appearance and interior lighting. Therefore, regular and effective cleaning of the exterior glass of high-rise buildings is essential for maintaining building quality, ensuring functionality, and protecting urban environmental hygiene.

[0003] Currently, the cleaning of exterior glass facades of high-rise buildings mainly relies on manual labor. Typically, a suspended platform, capable of accommodating one or two cleaners, is suspended from the rooftop by two main steel cables. During operation, the cleaners are positioned inside the suspended platform, wearing safety harnesses for secondary protection. Workers control the platform's height by operating its lifting mechanism, and upon reaching the designated floor, they manually move left and right within the limited platform space, using handheld cleaning tools to wipe and scrape the glass surface of the area covered by the platform.

[0004] However, the suspended platform is suspended high in the air by only two steel cables. When workers move left and right significantly inside the platform to clean different areas, the reaction force generated by their movements is directly transmitted to the platform, exacerbating its swaying and swinging. This increases the difficulty of operation and psychological pressure on the workers. Secondly, when two workers work together to clean in the same platform, the cleaning responsibility for the glass in the middle area where their work areas meet can easily become unclear: either both workers clean the area, or due to communication or line-of-sight problems, the area is missed by both, affecting the overall integrity and uniformity of the final cleaning effect. Utility Model Content

[0005] To overcome the drawbacks of swaying suspended platforms and missed cleaning areas, this utility model provides an intelligent automatic cleaning device for high-altitude exterior walls.

[0006] A smart high-altitude exterior wall cleaning device includes a suspended basket, a mounting frame, and air pipes. The suspended basket has fixed seats connected to both sides. A lead screw is rotatably connected between the fixed seats on one side, and a motor is mounted on the front of the fixed seat. The output shaft of the motor is connected to the front end of the lead screw. A guide rod is connected between the fixed seats on the other side. Connecting plates are connected to both ends of the mounting frame. One connecting plate is threaded to the lead screw, and the other connecting plate is slidably connected to the guide rod. A smart control terminal is installed inside the suspended basket. The motor is wired to the smart control terminal. An air pump is installed inside the smart control terminal. Several suction cups are installed on the rear side of the mounting frame. The air pump and all the suction cups are connected via air pipes. A cleaning mechanism for automatically cleaning glass is provided on the rear side of the mounting frame.

[0007] Preferably, the cleaning mechanism includes a fixed plate, a delivery pipe, and a water pump. Electric slide rails are installed on both the left and right sides of the mounting frame. The fixed plate is slidably connected to the electric slide rails. A brush is rotatably connected between the two fixed plates. A rack is connected to the rear side of the mounting frame. A gear that meshes with the rack is connected to the end of the brush. A scraper is connected to the top of both fixed plates. A water spray pipe is installed between the two fixed plates. A water tank is connected inside the basket. Clean water is delivered between the water tank and the water spray pipe through the delivery pipe. A water pump is installed at one end of the delivery pipe that extends into the water tank. The water pump and the electric slide rails are both wired to the intelligent control terminal.

[0008] Preferably, baffles are connected to both the left and right ends of the rear side of the mounting frame, a collection box is connected to the bottom of the mounting frame, the collection box is slidably connected to the basket, a guide plate is connected inside the collection box, and a drain outlet is opened on the front side of the collection box, with the drain outlet located in front of the lowest point of the guide plate.

[0009] Preferably, the baffle and the rear side of the collection box are connected with rubber pads.

[0010] Preferably, the hollow portion of the mounting frame is connected to a filter screen, and the flexible delivery pipe is slidably connected between the filter screens.

[0011] Preferably, the water tank has a transparent observation window on the front side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The motor drives the lead screw to push the connecting plate to move linearly along the guide rod, and the air pump draws air from the suction cup to form a negative pressure to adhere to the glass, so that the mounting frame and the glass form a rigid connection, completely fixing the position of the suspended basket. When the worker moves, the suspended basket shakes zero, improving the safety and stability of the operation.

[0014] 2. The fixed plate with brush moves longitudinally at a uniform speed through the electric slide rail. When the brush moves downward, the gear meshes with the fixed rack to force the brush to rotate at high speed. The cleaning path and number of reciprocations are precisely controlled by the intelligent terminal. The brush completely covers the glass surface, completely eliminating the problem of repeated or missed cleaning in the middle area caused by manual collaboration.

[0015] 3. By sealing the four sides of the work area through the compression deformation of the rubber pad, the wastewater is restricted from flowing into the collection box. After the filter screen intercepts debris, the guide plate directs the wastewater to the drain outlet. This closed system achieves zero high-altitude dripping of wastewater, avoiding environmental pollution and affecting pedestrians. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example: A smart high-altitude exterior wall cleaning device, such as... Figures 1-6As shown, the system includes a suspended platform 1, a fixed base 2, a motor 3, a lead screw 4, a connecting plate 5, a guide rod 6, a mounting bracket 7, a suction cup 14, a cleaning mechanism, an air pipe 18, an intelligent control terminal 19, and an air pump 20. Fixed bases 2 are connected to both sides of the suspended platform 1. A lead screw 4 is rotatably connected between the fixed bases 2 on one side, and a motor 3 is mounted on the front of the fixed base 2. The output shaft of the motor 3 is connected to the front end of the lead screw 4. A guide rod 6 is connected between the fixed bases 2 on the other side. Connecting plates 5 are connected to both ends of the mounting bracket 7. One connecting plate 5 is threadedly connected to the lead screw 4, and the other connecting plate 5 is threadedly connected to the guide rod 6. The rod 6 is slidably connected, the motor 3 drives the lead screw 4 to rotate, and pushes the connecting plate 5, which is threadedly connected to the lead screw 4, to move back and forth. The basket 1 is equipped with an intelligent control terminal 19. The motor 3 is wired to the intelligent control terminal 19. The intelligent control terminal 19 is equipped with an air pump 20. Two suction cups 14 are installed on the rear side of the mounting frame 7. The air pump 20 is connected to the two suction cups 14 through the air pipe 18. The air pump 20 draws air from the suction cups 14 through the air pipe 18 to form a negative pressure, which firmly adsorbs the mounting frame 7 onto the glass surface. The rear side of the mounting frame 7 is equipped with a cleaning mechanism for automatically cleaning the glass.

[0026] like Figures 2-4 As shown, the cleaning mechanism includes a fixed plate 8, an electric slide rail 9, a brush 10, a rack 11, a gear 12, a scraper 13, a water spray pipe 15, a water tank 16, a delivery pipe 17, and a water pump 171. Electric slide rails 9 are installed on both the left and right sides of the mounting frame 7. The fixed plate 8 is slidably connected to the electric slide rail 9. The brush 10 is rotatably connected between the two fixed plates 8. The electric slide rail 9 drives the two fixed plates 8 to move up and down synchronously, causing the water spray pipe 15 and the brush 10 to move longitudinally. A rack 11 is connected to the rear side of the mounting frame 7, and the end of the brush 10 is connected to a component that meshes with the rack 11. When the brush 10 moves downward, the gear 12 at its end meshes with the fixed rack 11, forcing the brush 10 to rotate at high speed. The top of the two fixed plates 8 are connected to a scraper 13. The scraper 13 scrapes away residual sewage when the fixed plates 8 move upward. A water spray pipe 15 is installed between the two fixed plates 8. A water tank 16 is connected inside the basket 1. Clean water is transported between the water tank 16 and the water spray pipe 15 through a conveying pipe 17. A water pump 171 is installed at one end of the conveying pipe 17 that extends into the water tank 16. The water pump 171 and the electric slide rail 9 are both wired to the intelligent control terminal 19.

[0027] like Figure 2 , Figure 6 and Figure 7As shown, it also includes baffles 21, collection boxes 22, guide plates 24, and filters 26. Baffles 21 are connected to both the left and right ends of the rear side of the mounting frame 7. The bottom of the mounting frame 7 is connected to the collection box 22, which is slidably connected to the basket 1. The guide plate 24 is connected inside the collection box 22. A drain outlet 23 is opened on the front side of the collection box 22, and the drain outlet 23 is located in front of the lowest point of the guide plate 24. The hollow part of the mounting frame 7 is connected to the filters 26. The gaps in the filters 26 ensure the accuracy of the staff's observation of the glass. The flexible conveying pipe 17 is slidably connected between the filters 26. When the cleaning wastewater flows down the glass, it is blocked by the baffles 21, collection boxes 22, and filters 26 sealed by the rubber gaskets 25 and flows into the collection box 22. The guide plate 24 directs the wastewater to the drain outlet 23.

[0028] like Figure 2 and Figure 6 As shown, it also includes a rubber pad 25, a baffle 21 and a collection box 22. The rubber pad 25 is connected to the rear side of the collection box 22. The top of the rubber pad 25 on the rear side of the collection box 22 is provided with a slope facing forward to guide the water flow into the collection box 22.

[0029] like Figure 5 As shown, it also includes an observation window 27. A transparent observation window 27 is provided on the front side of the water tank 16, through which staff can monitor the water level in the water tank 16 in real time.

[0030] Workers stand inside the suspended basket 1, which is suspended outside the building by steel cables. The rear of the mounting frame 7 is close to the glass. Before cleaning, the motor 3 is started via the intelligent control terminal 19. The motor 3 drives the lead screw 4 to rotate. The rotating lead screw 4 causes the connecting plate 5, which is slidably connected to it, to move backward. Through the guide rod 6 on the other side, the mounting frame 7 moves backward stably. At this time, the collection box 22, the baffle 21, and the suction cup 14 are all close to the glass. The air pump 20 is started via the intelligent control terminal 19. The air pump 20 draws out the air between the suction cup 14 and the glass through the air pipe 18, creating a negative pressure that fixes the suction cup 14 to the glass. At this time, the rubber pad 25 on the back of the baffle 21 and the collection box 22 is squeezed and undergoes elastic deformation, thereby sealing all areas on the back of the mounting frame 7. The mounting frame 7 is fixed by the suction cup 14, and the suspended basket 1 is also stabilized. The suspended basket 1 will not shake when the workers move.

[0031] During cleaning, staff activate water pump 171 via intelligent control terminal 19. Water pump 171 draws clean water from water tank 16 and sprays it onto the glass surface through spray pipe 15. Simultaneously, electric slide rail 9 is activated, driving two fixed plates 8 downwards. The brush 10 between the two fixed plates 8 and the spray pipe 15 also move downwards. The scraper 13 on top of the fixed plates 8 also moves downwards. As the spray pipe 15 moves downwards, it sprays clean water evenly. When the brush 10 drives gear 12 downwards, gear 12 meshes with rack 11, causing the brush 10 to rotate. The rotating brush 10 cleans the wet glass surface, while the scraper 13 removes residual wastewater from the glass surface, reducing water stains after cleaning. Electric slide rail 9 drives fixed plates 8 to move up and down repeatedly. The number of reciprocating movements is set via intelligent control terminal 19 according to the degree of contamination on the glass surface. Water pump 171 only activates each time the spray pipe 15 moves downwards, thus completing the cleaning of the glass surface.

[0032] The cleaning wastewater flows down the glass surface. Because the rubber pad 25 is in close contact with the glass, the wastewater is blocked by the rubber pad 25 at the bottom of the collection box 22 and the rubber pad 25 on the side of the baffle 21. It is also blocked by the filter screen 26 at the front. Then the wastewater enters the collection box 22 along the glass surface, reducing the possibility of wastewater dripping and affecting pedestrians. After the area is cleaned, the air pump 20 inflates the suction cup 14, causing the suction cup 14 to disconnect from the glass. The motor 3 is then started to reverse the screw 4, pulling the mounting bracket 7, suction cup 14, baffle 21 and collection box 22 forward. After the rubber pad 25 separates from the glass, it rebounds and moves to the next area to be cleaned via a steel cable, finally completing the cleaning work.

[0033] After the wastewater enters the collection tank 22, it is guided by the guide plate 24 to the drain outlet 23. After the basket 1 lands, the drain outlet 23 on the front of the collection tank 22 is opened to discharge the collected wastewater. Before the work starts, the amount of clean water is observed through the observation window 27 to ensure the use of clean water during the cleaning process.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
