Description

Technical Field

[0001] This application relates to the field of exterior wall cleaning operations, and in particular to a building exterior wall cleaning device. Background Technology

[0002] Currently, with the development of science and technology, the cleaning of building exterior walls is gradually shifting from manual cleaning to mechanical cleaning. Existing mechanical cleaning methods often involve fixing a traction device on the roof and then lowering the cleaning device down through the traction device. When cleaning the exterior wall surface, the cleaning device uses a vacuum suction cup to adhere to the exterior wall surface, thereby increasing the reliability of the cleaning device to the exterior wall surface.

[0003] However, the method of using vacuum suction cups to adhere to exterior wall surfaces is only suitable for smooth exterior wall surfaces, such as the surface of glass curtain walls, or the surface of smooth large tiles. However, for exterior wall surfaces with uneven surfaces, such as exterior wall surfaces formed by small tiles being pieced together, the vacuum suction cups cannot guarantee effective adhesion to the wall surface throughout the entire operation. This will affect the reliability of the connection between the cleaning device and the exterior wall surface, which will lead to a reduction in the cleaning quality of the wall surface. Summary of the Invention

[0004] To improve the cleaning quality of wall surfaces, this application provides a building exterior wall cleaning device.

[0005] The building exterior wall cleaning device provided in this application adopts the following technical solution:

[0006] The system includes a traction component, a sliding bracket, a cleaning component, and a water supply component. The traction component is equipped with a traction rope and is connected to the sliding bracket via the traction rope. The sliding bracket includes two parallel guide rails, sliders mounted on the two guide rails, and a threaded rod and a guide rod located between the two sliders and parallel to each other. The two ends of the threaded rod and the two ends of the guide rod are respectively connected to the two sliders, and the two sliders can slide synchronously on the two guide rails. The cleaning component includes a frame, a drive unit, and an exterior wall cleaning roller brush. The frame includes two side plates and a connecting plate. The two side plates are respectively mounted on the same side of the connecting plate and are parallel to each other. Both side plates have through holes for the threaded rod to pass through and guide holes for the guide rod to pass through. The exterior wall cleaning roller brush is located between the two side plates and is connected to the threaded rod by a threaded engagement. The drive unit is mounted on one of the side plates to drive the exterior wall cleaning roller brush to rotate. The water supply component is used to supply water to the cleaning position of the exterior wall cleaning roller brush.

[0007] By adopting the above technical solution, the traction component is installed above the wall. The traction component causes the sliding bracket to move perpendicularly to the ground while closely adhering to the exterior wall surface. During this movement, the water supply component supplies water to the wall surface, causing the water to flow down the wall surface. Then, the drive component one is activated, which drives the exterior wall cleaning roller brush to rotate, thereby cleaning the exterior wall. As the exterior wall cleaning roller brush rotates on the threaded rod, it moves along the axis of the threaded rod. When the exterior wall cleaning roller brush reaches the end of the threaded rod, the drive component one rotates in the opposite direction, driving the exterior wall... The cleaning roller brush moves in the opposite direction on the threaded rod. After the exterior wall cleaning roller brush completes one round trip on the threaded rod, the slider drives the exterior wall cleaning roller brush to move on the guide rail to achieve a larger cleaning area. Moreover, during the process of the traction component driving the sliding bracket to rise or fall, regardless of whether the wall surface is smooth or rough, the exterior wall cleaning roller brush can move up and down on the exterior wall through the traction component without relying on the vacuum suction cup to adhere to the wall. Therefore, it is suitable for both smooth and rough exterior walls and can effectively clean the exterior wall surface, thereby improving the cleaning quality.

[0008] Optionally, the traction assembly includes a traction base, a telescopic boom, a winch, and a slide rail. The traction base is mounted on the slide rail and can slide on the slide rail. One end of the telescopic boom is connected to the traction base, and the other end of the telescopic boom is connected to the winch. One end of the traction rope is wound around the winch, and the other end of the traction rope is connected to the guide rail.

[0009] By adopting the above technical solution, the winch is equipped with a traction rope, which is connected to the guide rail on the sliding bracket. This allows the sliding bracket to be pulled by the traction rope, thereby achieving vertical movement at the exterior wall. The traction base can slide on the guide rail, which enables the sliding bracket to move laterally at the exterior wall, making the sliding bracket's range of motion larger and thus the cleaning range larger.

[0010] Optionally, the water supply assembly includes a water tank, a water supply pipe, and a water outlet plate. One end of the water supply pipe is connected to the water tank, and the other end of the water supply pipe is connected to the water outlet plate. A water pump is installed on the water supply pipe. The water outlet plate is fixedly connected to the traction base. The water outlet plate is used to discharge water to the cleaning position of the exterior wall cleaning roller brush.

[0011] By adopting the above technical solution, when the water pump starts working, the water pump delivers water from the water tank to the water outlet plate through the water pipe. The water outlet plate sprays out the water delivered by the water pump, and the water sprayed out by the water outlet plate flows down the wall surface. Since the water outlet plate is located above the sliding bracket during cleaning, the water flowing out of the water outlet plate flows down the exterior wall surface and then flows to the contact position between the exterior wall cleaning roller brush and the exterior wall surface. The water not only washes away the dust on the exterior wall panel, but also wets the exterior wall surface, making it easier for the exterior wall cleaning roller brush to clean the exterior wall.

[0012] Optionally, the telescopic boom includes a connecting arm and an extending arm. One end of the connecting arm is connected to the traction base, and the other end of the connecting arm is sleeved on the extending arm. A second driving component is provided on the connecting arm, which is used to drive the extending arm to slide along the length of the connecting arm. The connecting arm is connected to the winch.

[0013] By adopting the above technical solution, the telescopic boom includes a connecting arm and an extending arm, and the extending arm is connected to the winch. This allows the extension length of the extending arm on the connecting arm to be adjusted when the second drive unit is started, so as to adjust the lowering position of the traction rope on the winch. This allows the distance between the traction rope and the wall surface to be adjusted, thereby making the sliding bracket move away from or close to the exterior wall surface.

[0014] Optionally, the drive unit is provided with a drive gear, and the end of the exterior wall cleaning roller brush near the drive unit is provided with a driven gear that meshes with the drive gear. The drive unit is also connected with a cleaning roller that is coaxial with the drive gear. The cleaning roller is used to clean the exterior wall cleaning roller brush.

[0015] By adopting the above technical solution, when the drive component is started, the active gear drives the driven gear to rotate, thereby realizing the rotation of the exterior wall cleaning roller brush. This allows the exterior wall cleaning roller brush to clean the surface of the exterior wall, while the cleaning roller is used to clean the exterior wall cleaning roller brush, so that dust and dirt on the wall surface will not accumulate excessively on the exterior wall cleaning roller brush and affect the cleaning effect of the exterior wall cleaning roller brush.

[0016] Optionally, a rotating shaft parallel to the axis of the cleaning roller is provided between the two side plates. A scraper is sleeved on the rotating shaft, and a torsion spring is provided between the scraper and the rotating shaft. The scraper abuts against the outer surface of the cleaning roller.

[0017] By adopting the above technical solution, the scraper, through the torsion spring, ensures that the cleaning roller remains in contact with the outer surface of the cleaning roller regardless of whether it is rotating forward or backward, thereby cleaning the dirt adhering to the outer surface of the cleaning roller, ensuring the cleanliness of the cleaning roller surface, and enabling the cleaning roller to maintain its cleaning effect on the exterior wall cleaning roller brush for a long time.

[0018] Optionally, water collection pads are provided on both sides of the scraper, and the water collection pads are connected to the scraper by adhesive bonding.

[0019] By adopting the above technical solution, the water collection pad is used to absorb the water squeezed out when the scraper comes into contact with the surface of the cleaning roller, which prevents excessive sewage from dripping from the top of the exterior wall. At the same time, the water collection pad is connected to the scraper by adhesive, which makes the water collection pad replaceable.

[0020] Optionally, an exhaust fan is provided on the connecting plate to direct airflow away from the cleaning roller.

[0021] By adopting the above technical solution, when the exhaust fan is started, it drives the external airflow through the cleaning roller and then blows it away from the cleaning roller. The exhaust fan makes the exterior wall cleaning roller brush fit more tightly with the exterior wall surface when in use. At the same time, it drives the airflow through the cleaning roller, so that the water in the cleaning roller can dry faster.

[0022] In summary, this application includes at least the following beneficial technical effects:

[0023] 1. The sliding bracket and the cleaning component on the sliding bracket are moved on the exterior wall surface by the traction component and the traction rope on the traction component. This makes it suitable for both smooth and rough exterior walls, and can effectively clean the exterior wall surface, thus improving the cleaning quality, because the exterior wall cleaning roller brush is moved up and down on the exterior wall by the traction component and does not need to rely on vacuum suction cups to adhere to the wall.

[0024] 2. By setting the scraper to contact the surface of the cleaning roller, the scraper cleans the surface of the cleaning roller when the cleaning roller rotates, thereby extending the cleaning time of the external wall cleaning roller brush. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a building exterior wall cleaning device, referring to... Figure 1-2 The system includes a traction assembly 1, a sliding bracket 2, a cleaning assembly 3, and a water supply assembly 4. The traction assembly 1 is located at the top of the wall and includes a traction base 15, a telescopic arm 16, a winch 17, and a slide rail 18. The slide rail 18 is fixedly connected to the top of the wall, and its length direction is parallel to the wall's extension direction parallel to the ground. The traction base 15 is slidably connected to the slide rail 18. A motor is installed on the traction base 15 to drive the traction base 15 to slide along the slide rail 18 along its length direction. One end of the telescopic arm 16 is connected to the traction base 15, and the other end is connected to the winch 17. A traction rope 5 is wound around the winch 17 and is connected to the sliding bracket 2. The sliding bracket 2 is close to the outer wall surface. When the winch 17 is operating, the traction rope 5 drives the sliding bracket 2 to rise or fall vertically along the wall surface. The cleaning assembly 3 is installed on the sliding bracket 2.

[0032] Furthermore, the telescopic boom 16 includes a connecting arm 23 and an extending arm 22. One end of the connecting arm 23 is connected to the traction base 15, and the other end of the connecting arm 23 is sleeved on the extending arm 22. The side wall of the connecting arm 23 is provided with an opening groove whose extension direction is consistent with the length direction of the connecting arm 23. The extending arm 22 is provided with a toothed groove at the position of the side wall where the opening groove is located. A second driving component 32 is installed on the connecting arm 23. The second driving component 32 can be a drive motor. A gear that meshes with the toothed groove is installed on the output shaft of the second driving component 32. This allows the motor on the connecting arm 23 to drive the extending arm 22 to extend or retract on the connecting arm 23 after starting, so as to adjust the extension length of the extending arm 22 on the connecting arm 23. The end of the extending arm 22 away from the connecting arm 23 is connected to the winch 17.

[0033] The water supply component 4 includes a water tank 19, a water pipe 20, and a water outlet plate 21. The water tank 19 can be a self-made water tank or a water tank 19 that is installed on the top of the wall. A water pump is installed on the water pipe 20, and one end of the water pipe 20 is connected to the water tank 19, while the other end of the water pipe 20 is connected to the water outlet plate 21. The water outlet plate 21 is fixedly connected to the traction base 15, and the water outlet on the water outlet plate 21 is close to the surface of the exterior wall. This allows the water flowing from the water outlet plate 21 to flow along the surface of the exterior wall before and during the cleaning of the exterior wall by the cleaning component 3, thereby working with the cleaning component 3 to clean the surface of the exterior wall.

[0034] Reference Figure 2 and Figure 3 The cleaning component 3 is mounted on the sliding bracket 2. The sliding bracket 2 includes two parallel guide rails 6. Both ends of the two guide rails 6 are connected to fixed beams. Slider 7 is provided on the two guide rails 6 respectively. One of the sliders 7 is equipped with a motor for driving the slider 7 to move on the guide rail 6. The guide rail 6 that slides with the slider 7 equipped with the motor is provided with a toothed groove. The motor on the slider 7 realizes the movement of the slider 7 on the guide rail 6 by installing a gear that meshes with the toothed groove.

[0035] Between the two sliders 7, a guide rod 9 and a threaded rod 8 are provided. The two ends of the guide rod 9 and the two ends of the threaded rod 8 are respectively fixedly connected to the two sliders 7. The cleaning assembly 3 includes a frame 10, a drive component 11, and an exterior wall cleaning roller brush 12. The frame 10 includes two parallel side plates 13 and a connecting plate 14 for connecting the two side plates 13. Both side plates 13 are mounted on the same side of the connecting plate 14. Both side plates 13 have through holes for the threaded rod 8 to pass through and guide holes for the guide rod 9 to pass through. The exterior wall cleaning roller brush 12 is located between the two side plates 13 and is connected to the threaded rod 8 by a threaded engagement. The drive component 11... The drive unit 11 is installed on one of the connecting plates 14. The drive unit 11 can be a motor. A drive gear 24 is installed on the output shaft of the drive unit 11. A driven gear 25 that meshes with the drive gear 24 is provided at the end of the exterior wall cleaning roller brush 12 near the drive unit. When the drive unit 11 is started, the drive gear 24 drives the exterior wall cleaning roller brush 12 to rotate on the threaded rod 8 through the meshing between the drive gear 24 and the driven gear 25. This allows the exterior wall cleaning roller brush 12 to clean the exterior wall on the threaded rod 8 and reciprocate along the axis of the threaded rod 8. This allows the exterior wall cleaning roller brush 12 to not only clean the exterior wall by rotating, but also wipe the surface of the wall by moving on the threaded rod 8.

[0036] Furthermore, a cleaning roller 26 coaxial with the drive gear 24 is also provided on the drive component 11. The outer diameter of the cleaning roller 26 is smaller than the outer diameter of the exterior wall cleaning roller brush 12, and the outer surface of the cleaning roller 26 is in close contact with the surface of the exterior wall cleaning roller. The cleaning roller 26 has a water absorption function. The cleaning roller 26 is used to clean the exterior wall cleaning roller brush 12 while cleaning the exterior wall, so that the exterior wall cleaning roller brush 12 can maintain a clean state for a longer time when cleaning the exterior wall, thereby enabling the exterior wall cleaning roller brush 12 to maintain a good cleaning effect on the exterior wall surface.

[0037] Reference Figure 3 and Figure 4 Furthermore, in order to ensure that the cleaning roller 26 can maintain its cleaning function on the exterior wall cleaning roller brush 12 for a long time, a rotating shaft 27 is provided between the two side plates 13. The axis of the rotating shaft 27 is parallel to the axis of the cleaning roller 26. A scraper 28 is sleeved on the rotating shaft 27 and can rotate around the axis of the rotating shaft 27. A torsion spring 29 is also provided between the scraper 28 and the rotating shaft 27. This ensures that the scraper 28 can maintain its contact with the surface of the cleaning roller 26 regardless of whether the cleaning roller 26 rotates forward or backward under the drive of the drive component 11, thereby scraping off the dirt adhering to the surface of the cleaning roller 26. At the same time, the cleaning roller 26 can be squeezed when rotating, thereby squeezing out the sewage absorbed inside the cleaning roller 26, so that the cleaning roller 26 can maintain its cleaning function on the exterior wall cleaning roller brush 12 for a long time.

[0038] On both sides of the scraper 28, there are water collection pads 30. The water collection pads 30 can be made of cotton cloth or sponge. The water collection pads 30 are connected to the scraper 28 by adhesive. This allows the wastewater scraped off by the scraper 28 from the cleaning roller 26 to be absorbed by the water collection pads 30, thereby reducing the occurrence of wastewater dripping. The adhesive connection between the water collection pads 30 and the scraper 28 also makes the water collection pads 30 easy to replace. After the wastewater in the water collection pads 30 is squeezed out, they can still be used normally.

[0039] Reference Figure 1 An exhaust fan 31 is also provided on the connecting plate 14. The exhaust fan 31 is used to drive the airflow to be discharged away from the cleaning roller 26 after passing through the cleaning roller 26. This means that after the exhaust fan 31 is started, it will draw the airflow through the cleaning roller 26 and discharge it through the exhaust fan 31. This not only speeds up the evaporation of water in the cleaning roller 26, but also increases the tightness between the exterior wall cleaning roller brush 12 and the exterior wall surface.

[0040] In this application, the motors on the drive unit 11 and the traction base 15 used to drive the traction base 15 to slide on the slide rail 18 may not have a braking function, while the drive unit 2, the motor mounted on the connecting arm 23 and the motor mounted on the slider 7 need to have a braking function.

[0041] The implementation principle of this application embodiment is as follows: Adjust the extension length of the telescopic arm 16 on the traction base 15 so that the exterior wall cleaning roller brush 12 can press against the exterior wall surface during vertical movement. Then, start the winch 17 to lower the sliding bracket 2 and start the water pump. The water in the water tank 19 flows to the water outlet plate 21 through the water pipe 20 and is finally discharged through the water outlet plate 21. The water flows down the wall and wets the exterior wall surface. Then, start the exhaust fan 31 and the drive component 11 respectively. The drive component 11 drives the exterior wall cleaning roller brush 12 and the cleaning roller 26 to rotate together. While the exterior wall cleaning roller brush 12 rotates, the cleaning roller 26 cleans the exterior wall cleaning roller brush 12, while the scraper 28 cleans the cleaning roller 26. As the exterior wall cleaning roller brush 12 rotates, the entire frame 10 moves along the length of the threaded rod 8. When the exterior wall cleaning roller brush 12 moves to one end of the threaded rod 8, the drive component 11 changes the direction of rotation, thereby causing the exterior wall cleaning roller brush 12 to move towards the other end of the threaded rod 8. Repeating this back and forth once or multiple times is considered as the cleaning of the wall surface that is in contact with the exterior wall cleaning roller brush 12.

[0042] After the current position is cleaned, the drive unit 11 stops running, and the slider 7 moves a distance along the length of the guide rail 6 under the action of the motor. Then the drive unit 11 is restarted, and the exterior wall cleaning roller brush 12 starts to rotate again and cleans a new area on the exterior wall surface.

[0043] When the slider 7 moves to the travel limit on the guide rail 6, the winch 17 starts running and continues to lower the cleaning component to a certain extent, restarting the cleaning of the exterior wall. At this time, the slider 7 will move towards the travel limit at the other end of the guide rail 6.

[0044] Once the vertical cleaning of the exterior wall surface is completed, the traction base 15 moves on the slide rail 18, enabling the exterior wall cleaning roller brush 12 to move laterally on the exterior wall surface, thereby cleaning the exterior wall surface.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
