Description

Technical Field

[0001] This invention relates to the field of curtain wall cleaning technology, specifically to a cleaning device and method for building curtain wall panels. Background Technology

[0002] Several curtain wall panels, together with their supporting frames, can form a building curtain wall. During long-term use, the surface of a building curtain wall is easily contaminated with dust, dirt, bird droppings, and various air pollutants. To prevent these pollutants from affecting the overall aesthetics of the curtain wall, cleaning devices are needed to remove them from the panels.

[0003] The cleaning device can move up and down on the outside of the building curtain wall via a suspension mechanism. During the movement, the cleaning device can clean the contaminants attached to the curtain wall panels using cleaning brushes. During the cleaning process, some contaminants tend to adhere to the cleaning brushes. Since the cleaning device operates at a height, the contaminants adhering to the cleaning brushes cannot be cleaned in time. When the cleaning brushes clean the curtain wall panels, the contaminants adhering to the cleaning brushes will rub against the curtain wall panels, resulting in scratches on the surface of the curtain wall panels due to friction.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a cleaning device and method for building curtain wall panels, which has the advantages of preventing contaminants removed during cleaning from rubbing against the surface of the curtain wall panels, thus solving the problem of scratches on the surface of the curtain wall panels caused by friction between contaminants and the panels.

The bottom of the collecting frame is inclined. One end of the shovel plate is in contact with the inner wall of the collecting frame. A through groove is provided on the front of the outer shell. A support frame is fixedly connected to the inner wall of the outer shell. A collecting box is movably connected to the through groove and the inside of the support frame. A filter screen is fixedly connected inside the collecting box. A material drop chute is provided on the lower side of the collecting frame.

[0011] Preferably, the rinsing assembly includes a water pump, which is fixedly installed inside the housing on one side. A suction pipe is fixedly installed at the suction end of the water pump, and a transport pipe is fixedly installed at the output end of the water pump. A diversion pipe is fixedly connected to one end of the transport pipe, and a plurality of rinsing nozzles are fixedly connected to the outer surface of the diversion pipe. The diversion pipe is located at the top of the inner wall of the housing. Fixing brackets are fitted onto the outer surfaces of the suction pipe, the transport pipe, and the diversion pipe, and a plurality of fixing brackets are fixedly installed on the inner wall of the housing.

[0012] Preferably, the movable support assembly includes a support frame, which is fixedly installed on the back of the housing. A small roller is rotatably connected to one side of the support frame and is located on the upper side of the mounting groove. A support box is fixedly connected to the back of the housing. A support shaft is rotatably connected inside the support box. One end of the support shaft passes through the support box and is fixedly connected to a large roller, which is located on the lower side of the mounting groove.

[0013] Preferably, the linkage assembly includes a linkage rod, and the outer surface of the linkage rod and the outer surface of the support shaft are both fixedly connected with linkage bevel gears. The two linkage bevel gears mesh together. The bottom end of the drive shaft passes through the mounting box and the collection frame in sequence, and the bottom end of the drive shaft extends into the interior of the support box. The outer surfaces of the drive shaft and the linkage rod are both fixedly connected with drive bevel gears. The two drive bevel gears mesh together. The bottom of the inner wall of the support box is fixedly connected with a support plate, and the linkage rod is rotatably connected to the support plate.

[0014] Preferably, a connecting ring is fixedly connected to the top and bottom of the outer shell, a guide plate is fixedly installed on the back of the outer shell, an inclined guide groove is opened at the bottom of the guide plate, and a guide rod is fixedly connected to the top of several shovels corresponding to the inclined guide groove.

[0015] A cleaning method based on the aforementioned building curtain wall panel cleaning device: The suspension device is connected to the outer shell through the connecting ring. Under the suspension of the suspension device, the small roller, the large roller, several shovels and the collection frame are all in contact with the outer surface of the curtain wall panel. The outer shell is moved on the outside of the curtain wall panel by the suspension device. At this time, the small roller and the large roller can roll on the curtain wall panel. The large roller drives the linkage rod to rotate on the support plate through the support shaft and the meshing linkage bevel gear. The linkage rod drives the drive shaft to rotate through the meshing drive bevel gear. The drive shaft drives several connecting frames to rotate inside the drive groove through the sprocket and chain. As a result, the several connecting frames drive the corresponding shovel plates to move out of the collection frame through the installation groove. The shovel plate that moves out from inside the collection frame can tilt and contact the curtain wall panel under the elastic force of the torsion spring. At the same time, driven by the chain, the shovel plate can tilt and remove the contaminants on the curtain wall panel. Some of the removed impurities fall into the inside of the collection frame under their own gravity. The contaminants inside the collection frame can roll into the collection box through the drop chute under the guidance of the collection frame. When the shovel is about to move into the inside of the collection frame, the guide rod at the top of the shovel can move into the inside of the inclined guide groove. At this time, the inclined guide groove allows the shovel to rotate to one side of the outer shell through the guide rod. When the shovel moves into the inside of the collection frame, the guide rod moves out from the inside of the inclined guide groove, and at the same time, the shovel contacts the inner wall of the collection frame at an inclination under the elastic force of the torsion spring. The water pump can draw cleaning fluid from inside the outer casing through the extraction pipe. The extracted cleaning fluid flows into the inside of the diversion pipe under the guidance of the transport pipe. Several of the rinsing nozzles can rinse the shovel plate that moves inside the collection frame. The contaminants adhering to the shovel plate can be removed from the shovel plate by the rinsing of the cleaning fluid. The removed contaminants flow into the inside of the collection box under the drive of the cleaning fluid. The collection box then filters out the contaminants, while the cleaning fluid falls back to the bottom of the outer casing.

[0016] Compared with the prior art, the present invention provides a cleaning device and method for building curtain wall panels: 1. This invention enables several scraping components to continuously move in a curved path and scrape away contaminants from the surface of the curtain wall panel through a driving component. Since the scraping components clean the contaminants on the curtain wall panel in the form of scrapers, the scraping components will not cause friction between the scraped contaminants and the curtain wall panel when they move. In addition, after the scraping components move into the inner shell, the rinsing component can rinse away the contaminants adhering to the scraping components. Thus, when the scraping components come into contact with the curtain wall panel again, there are no contaminants on the surface. The above settings effectively avoid scratches on the surface of the curtain wall panel caused by friction between the scraped contaminants and the curtain wall panel.

[0017] 2. This invention brings a large roller into contact with the outer surface of the curtain wall panel, allowing the large roller to rotate on the curtain wall panel as the outer casing moves. The large roller, through a support shaft, a linkage bevel gear, a linkage rod, and a drive bevel gear, drives the drive shaft to rotate. This, in turn, causes the drive shaft to drive several shovels to move in a curved path via sprockets, chains, and several connecting frames. This arrangement links the movement speed of the shovels to the movement speed of the outer casing. This configuration ensures that regardless of the movement of the outer casing, several shovels can move from the same position on the curtain wall panel, thus ensuring that the effectiveness of the shovels in removing contaminants from the curtain wall panel is not affected by the movement speed of the outer casing.

[0018] 3. When the shovel plate is moved into the interior of the outer shell by the sprocket and chain, the guide rod at the top of the shovel plate can move into the inclined guide groove. As the guide rod moves continuously inside the inclined guide groove, it can pull the shovel plate to one side of the outer shell. When the shovel plate moves into the interior of the collection frame, the guide rod moves out from the interior of the inclined guide groove. At the same time, under the action of the torsion spring, the shovel plate contacts the inner wall of the collection frame in a shoveling manner. The inclined guide groove and guide rod can prevent the shovel plate from getting stuck or locked when it moves into the collection frame due to the contact position between the collection frame and the curtain wall panel, thus allowing the shovel plate to move normally into the interior of the collection frame in a shoveling manner.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a cleaning device and cleaning method for building curtain wall panels.

[0023] Please see Figure 1-11 A cleaning device for building curtain wall panels includes a housing 1, an installation groove 2 on the back of the housing 1, a plurality of scraping components 3 arranged in a curved array inside the installation groove 2, a driving component 4 inside the installation groove 2, the driving end of the driving component 4 being connected to the plurality of scraping components 3, a collecting component 5 being arranged below the scraping components 3, a rinsing component 6 inside the housing 1, the rinsing end of the rinsing component 6 being vertically aligned with the plurality of scraping components 3, a movable support component 7 on the back of the housing 1, and a linkage component 8 between the movable support component 7 and the driving component 4. By bringing the movable support assembly 7 into contact with the curtain wall panel, a plurality of scraping components 3 on the outside of the housing 1 come into contact with the curtain wall panel. When the housing 1 moves the movable support assembly 7 up and down, the movable support assembly 7 drives the drive assembly 4 through the linkage assembly 8, so that the plurality of scraping components 3 move in a curved path and clean the curtain wall panel. The collection assembly 5 is used to collect the pollutants that have been cleaned up, and the flushing assembly 6 is used to flush the scraping components 3 that have moved into the housing 1.

[0024] The hoisting device housing 1 can move up and down on the outside of the curtain wall panel. At this time, the moving support assembly 7 can roll on the outer surface of the curtain wall panel. Simultaneously, the moving support assembly 7 can drive the drive assembly 4 through the linkage assembly 8, thereby causing the drive assembly 4 to move several scraping components 3 out from inside the housing 1 and directly contact the curtain wall panel. Driven by the drive assembly 4, the scraping components 3 can scrape off the contaminants on the curtain wall panel. The scraped contaminants fall into the collection assembly 5 under their own gravity. At the same time, when the scraping components 3 move back into the housing 1 under the drive assembly 4, the flushing assembly 6 can flush off the contaminants adhering to the surface of the scraping components 3, and the contaminants fall into the collection assembly 5 under the flushing liquid.

[0025] The drive component 4 enables several scraping components 3 to continuously move in a curved path and scrape away contaminants from the surface of the curtain wall panel. Since the scraping components 3 clean the contaminants on the curtain wall panel in the form of scrapers, the scraping components 3 do not cause friction between the scraped contaminants and the curtain wall panel when they move. In addition, after the scraping components 3 move into the housing 1, the flushing component 6 can wash away the contaminants adhering to the scraping components 3. As a result, when the scraping components 3 come into contact with the curtain wall panel again, there are no contaminants on its surface. The above settings effectively avoid scratches on the surface of the curtain wall panel caused by friction between the scraped contaminants and the curtain wall panel.

[0026] Furthermore, for the aforementioned scraping component 3, the scraping component 3 includes a connecting frame 301, a mounting block 302 is fixedly connected to one side of the connecting frame 301, a rotating shaft 303 is rotatably connected inside the mounting block 302, both ends of the rotating shaft 303 pass through the mounting block 302, a scraper plate 304 is fixedly fixed to the outer surface of the rotating shaft 303, mounting cylinders 305 are fixedly installed at the top and bottom of the mounting block 302, the rotating shaft 303 is rotatably connected to the mounting cylinder 305, and a torsion spring 306 is fixedly connected between the inner wall of the mounting cylinder 305 and the outer surface of the rotating shaft 303.

[0027] After the drive assembly 4 moves the scraper plate 304 out of the housing 1 via the connecting bracket 301, the scraper plate 304 can directly contact the curtain wall panel. At this time, the torsion spring 306 can pull the rotating shaft 303, allowing the rotating shaft 303 to rotate on the mounting block 302. Simultaneously, the scraper plate 304 can rotate to one side of the curtain wall panel under the drive of the rotating shaft 303. Under the elastic force of the torsion spring 306, when scraping away contaminants on the curtain wall panel, the scraper plate 304 can make close contact with the curtain wall panel, thus ensuring effective removal of contaminants. The cleaning effect of the contaminants can be guaranteed, and the scraper plate 304 will not cause wear to the surface of the curtain wall panel due to excessive squeezing force. When the scraper plate 304 moves on the curtain wall panel, the contaminants on the curtain wall panel can be removed from the curtain wall panel by the scraper plate 304 and can move to the outer surface of the scraper plate 304. This setting ensures that the scraper plate 304 will not squeeze the removed contaminants when it moves, thereby avoiding the phenomenon of contaminants rubbing against the curtain wall panel. Most of the contaminants on the scraper plate 304 will fall directly into the interior of the collection component 5 under the action of gravity.

[0028] Furthermore, for the aforementioned drive assembly 4, the drive assembly 4 includes a mounting box 401, which is fixedly installed on the top of the inner wall of the mounting groove 2. Two drive shafts 402 are rotatably connected inside the mounting box 401. Sprockets 403 are fixedly connected to the outer surfaces of the two drive shafts 402. Chains 404 are meshed on the outer surfaces of the sprockets 403. A drive groove 405 is provided on the outer surface of the mounting box 401. The connecting frame 301 is connected to the chain 404 through the drive groove 405. A connecting rod 406 is fixedly installed between the top and bottom of the inner wall of the mounting box 401.

[0029] By driving the drive shaft 402, the drive shaft 402 drives the chain 404 to move inside the mounting box 401 via the sprocket 403. The continuously moving sprocket 403 can drive several connecting frames 301 to move inside the drive groove 405, so that the connecting frames 301 can drive the scraper 304 to move in a curved path outside the mounting box 401. The mounting box 401 is designed so that when cleaning the curtain wall panels, the contaminants cleaned off will not fall onto the sprocket 403 and chain 404, so that the sprocket 403 and chain 404 can drive the connecting frames 301 normally. At the same time, the connecting rod 406 inside the mounting box 401 prevents the mounting box 401 from separating due to the drive groove 405, so that the overall protective effect of the mounting box 401 can be guaranteed.

[0030] Furthermore, for the aforementioned connecting frame 301, a limiting rod 407 is fixedly connected to the outer surface of the connecting frame 301, a limiting groove 408 is formed on the inner wall of the mounting box 401, the limiting rod 407 is movably connected to the limiting groove 408, and a shielding strip 409 is sleeved on the outer surface of the mounting box 401 corresponding to the driving groove 405, and the shielding strip 409 is connected together with several connecting frames 301.

[0031] When the connecting brackets 301 move inside the drive groove 405, the shielding strip 409 can move outside the mounting box 401 under the drive of the connecting brackets 301. The moving shielding strip 409 always keeps the drive groove 405 blocked. This setting further improves the protection effect of the mounting box 401 on the sprocket 403 and chain 404 inside. When the connecting brackets 301 move, they can drive the limiting rod 407 to move inside the limiting groove 408. The setting of the limiting rod 407 and the limiting groove 408 ensures that the connecting brackets 301 will not shake when moving.

[0032] Furthermore, for the aforementioned collection component 5, the collection component 5 includes a collection frame 501, which is fixedly connected to the bottom of the inner wall of the mounting groove 2. The bottom of the collection frame 501 is inclined. One end of the shovel plate 304 is in contact with the inner wall of the collection frame 501. A through groove 502 is provided on the front of the outer shell 1. A support frame 503 is fixedly connected to the inner wall of the outer shell 1. A collection box 504 is movably connected to the inside of the through groove 502 and the support frame 503. A filter screen 505 is fixedly connected to the inside of the collection box 504. A material drop chute 506 is provided on the lower side of the collection frame 501.

[0033] One end of the collection frame 501 contacts the outer side of the curtain wall panel. The pollutants removed by the shovel 304 can fall directly into the collection frame 501 under their own weight. Due to the inclined bottom of the collection frame 501, the pollutants inside the collection frame 501 can automatically roll downwards and fall into the collection box 504 through the drop chute 506. When cleaning the collected pollutants, the collection box 504 can be directly pulled out from the inside of the outer shell 1 through the through groove 502. This setting makes it convenient to clean the collected pollutants. The shovel 304 can move into the collection frame 501 in a shovel-like state under the drive of the connecting frame 301 and the chain 404. Under the restriction of the collection frame 501, when the shovel 304 moves to the curtain wall panel again, it still contacts the curtain wall panel in a shovel-like state.

[0034] Furthermore, for the above-mentioned rinsing assembly 6, the rinsing assembly 6 includes a water pump 601, the water pump 601 is fixedly installed inside one side of the housing 1, the extraction end of the water pump 601 is fixedly installed with an extraction pipe 602, the output end of the water pump 601 is fixedly installed with a transport pipe 603, one end of the transport pipe 603 is fixedly connected to a diversion pipe 604, a plurality of rinsing nozzles 605 are fixedly connected to the outer surface of the diversion pipe 604, the diversion pipe 604 is disposed at the top of the inner wall of the housing 1, and the outer surfaces of the extraction pipe 602, the transport pipe 603 and the diversion pipe 604 are all fitted with fixing brackets 606, and a plurality of fixing brackets 606 are fixedly installed on the inner wall of the housing 1.

[0035] The outer casing 1 stores cleaning fluid. The water pump 601 can extract the cleaning fluid from the outer casing 1 through the extraction pipe 602. The extracted cleaning fluid can flow into the diversion pipe 604 under the transport pipe 603. At the same time, the flushing nozzle 605 can spray the cleaning fluid in the diversion pipe 604 onto the scraper 304 passing under the flushing nozzle 605. At this time, the contaminants adhering to the surface of the scraper 304 can be removed from the scraper 304 under the impact of the cleaning fluid and fall into the collection frame 501 along with the cleaning fluid. Then, the contaminants in the collection frame 501 can flow into the collection box 504 through the drop chute 506 under the action of the cleaning fluid. The collection box 504 filters the contaminants through the filter screen 505, while the cleaning fluid flows back into the outer casing 1. This setting allows the cleaning fluid to be reused, thereby effectively avoiding the waste of cleaning fluid when cleaning curtain wall panels.

[0036] Furthermore, for the aforementioned movable support assembly 7, the movable support assembly 7 includes a support frame 701, which is fixedly installed on the back of the outer casing 1. A small roller 702 is rotatably connected to one side of the support frame 701. The small roller 702 is disposed on the upper side of the mounting groove 2. A support box 703 is fixedly connected to the back of the outer casing 1. A support shaft 704 is rotatably connected inside the support box 703. One end of the support shaft 704 passes through the support box 703 and is fixedly connected to a large roller 705. The large roller 705 is disposed on the lower side of the mounting groove 2.

[0037] When the outer casing 1 is suspended on the outside of the curtain wall panel, the large roller 705 and the small roller 702 can come into contact with the outside of the curtain wall panel. At the same time, when the outer casing 1 moves up and down on the outside of the curtain wall panel, the two rollers can rotate on the curtain wall panel. The arrangement of the two rollers ensures that the outer casing 1 will not collide with the curtain wall panel when it moves up and down.

[0038] Furthermore, for the aforementioned linkage component 8, the linkage component 8 includes a linkage rod 801. The outer surface of the linkage rod 801 and the outer surface of the support shaft 704 are both fixedly connected to linkage bevel gears 802. The two linkage bevel gears 802 mesh together. The bottom end of the drive shaft 402 passes through the mounting box 401 and the collection frame 501 in sequence. At the same time, the bottom end of the drive shaft 402 extends into the interior of the support box 703. The outer surfaces of the drive shaft 402 and the linkage rod 801 are both fixedly connected to drive bevel gears 803. The two drive bevel gears 803 mesh together. The bottom of the inner wall of the support box 703 is fixedly connected to a support plate 804. The linkage rod 801 and the support plate 804 are rotatably connected together.

[0039] When the large roller 705 rotates as the outer casing 1 moves, the large roller 705 drives the linkage rod 801 to rotate on the support plate 804 through the support shaft 704 and two meshing linkage bevel gears 802. The linkage rod 801 then drives the drive shaft 402 to rotate through two meshing drive bevel gears 803. This causes the drive shaft 402 to drive several shovels 304 to move in a curved path through the sprocket 403, chain 404, and several connecting frames 301. The above arrangement links the moving speed of the shovels 304 with the moving speed of the outer casing 1. This arrangement ensures that no matter how the outer casing 1 moves, several shovels 304 can move from the same position on the curtain wall panel. Therefore, the effect of the shovels 304 in removing contaminants from the curtain wall panel is not affected by the moving speed of the outer casing 1.

[0040] Furthermore, for the aforementioned outer shell 1, a connecting ring 9 is fixedly connected to both the top and bottom of the outer shell 1, a guide plate 10 is fixedly installed on the back of the outer shell 1, an inclined guide groove 11 is provided at the bottom of the guide plate 10, and a guide rod 12 is fixedly connected to the top of several shovel plates 304 corresponding to the inclined guide groove 11.

[0041] Lifting devices are installed at both the top and bottom of the building. The traction ends of the two lifting devices are connected to the connecting rings 9 at the top and bottom of the outer shell 1, respectively. When the outer shell 1 moves, the lifting device at the top of the building continuously extends the traction end outward, while the lifting device at the bottom of the building continuously retracts the traction end. This allows the outer shell 1 between the two traction ends to move downward, and the outer shell 1 is less prone to swaying during movement under the pull of the two traction ends. When the shovel plate 304 is about to move into the collection frame 501, the guide rod 12 at the top of the shovel plate 304 can move into the inclined guide groove 11. As the shovel plate 304 moves continuously outside the mounting box 401, the guide rod 12 can move into the inclined guide groove 11. The guide rod 12 moves towards the inside of the inclined guide groove 11 and pulls the shovel plate 304 towards one side of the outer shell 1 under the guidance of the inclined guide groove 11. When the shovel plate 304 moves into the inside of the collection frame 501, the guide rod 12 moves out from the inside of the inclined guide groove 11. At this time, the torsion spring 306 can drive the shovel plate 304 to rotate through the rotating shaft 303 and make the shovel plate 304 contact the inner wall of the collection frame 501. The inclined guide groove 11 and the guide rod 12 can prevent the shovel plate 304 from getting stuck and locked when it moves into the inside of the collection frame 501 due to the contact position between the collection frame 501 and the curtain wall panel. This allows the shovel plate 304 to move normally into the inside of the collection frame 501 in the form of a shovel.

[0042] Through the above technical solution: 1. The driving component 4 enables several scraping components 3 to continuously move in a curved path and scrape away contaminants from the surface of the curtain wall panel. Since the scraping components 3 clean the contaminants on the curtain wall panel in the form of scrapers, the scraping components 3 do not cause friction between the scraped-off contaminants and the curtain wall panel when they move. In addition, after the scraping components 3 move into the housing 1, the rinsing component 6 can rinse away the contaminants adhering to the scraping components 3. Thus, when the scraping components 3 come into contact with the curtain wall panel again, there are no contaminants on their surface. The above settings effectively avoid... 1. The surface of the curtain wall panel is scratched due to friction between the removed contaminants and the panel. 2. By bringing the large roller 705 into contact with the outer surface of the curtain wall panel, the large roller 705 can rotate on the curtain wall panel when the outer casing 1 moves. The large roller 705 drives the drive shaft 402 to rotate via the support shaft 704, the linkage bevel gear 802, the linkage rod 801, and the drive bevel gear 803. This causes the drive shaft 402 to drive several scraper plates 304 to move in a curved path via the sprocket 403, the chain 404, and several connecting frames 301. The above configuration... The moving speed of the scraper plate 304 can be linked to the moving speed of the outer casing 1. This setting allows multiple scraper plates 304 to move from the same position on the curtain wall panel regardless of the movement of the outer casing 1, thus ensuring that the scraper plate 304's effect on removing contaminants from the curtain wall panel is not affected by the moving speed of the outer casing 1; 3. When the scraper plate 304 is moved into the interior of the outer casing 1 by the sprocket 403 and chain 404, the guide rod 12 at the top of the scraper plate 304 can move into the interior of the inclined guide groove 11. As the guide rod 12 continuously moves within the inclined guide groove 11, the guide... The guide rod 12 can pull the shovel plate 304 to one side of the outer casing 1. When the shovel plate 304 moves into the inside of the collection frame 501, the guide rod 12 moves out from the inside of the inclined guide groove 11. At the same time, under the elastic force of the torsion spring 306, the shovel plate 304 contacts the inner wall of the collection frame 501 in a shovel-like manner. The inclined guide groove 11 and the guide rod 12 can prevent the shovel plate 304 from getting stuck and locked when it moves into the inside of the collection frame 501 due to the contact position between the collection frame 501 and the curtain wall panel. This allows the shovel plate 304 to move normally into the inside of the collection frame 501 in a shovel-like manner.

[0043] A cleaning method based on the aforementioned building curtain wall panel cleaning device: The suspension device is connected to the outer shell 1 via the connecting ring 9. Under the suspension of the suspension device, the small roller 702, the large roller 705, several shovels 304 and the collection frame 501 are all in contact with the outer surface of the curtain wall panel. The outer casing 1 is moved on the outside of the curtain wall panel by the suspension device. At this time, the small roller 702 and the large roller 705 can roll on the curtain wall panel. The large roller 705 drives the linkage rod 801 to rotate on the support plate 804 through the linkage bevel gear 802 meshing with the support shaft 704. The linkage rod 801 drives the drive shaft 402 to rotate through the drive bevel gear 803 meshing with it. The drive shaft 402 drives several connecting frames 301 to rotate inside the drive groove 405 through the sprocket 403 and the chain 404. Thus, the several connecting frames 301 drive the corresponding shovel plates 304 to move out of the collection frame 501 through the mounting groove 2. The shovel plate 304, which moves out from inside the collection frame 501, can tilt and contact the curtain wall panel under the elastic force of the torsion spring 306. At the same time, driven by the chain 404, the shovel plate 304 can tilt and remove the contaminants on the curtain wall panel. Some of the removed impurities fall into the collection frame 501 under their own weight. The contaminants inside the collection frame 501 can roll into the collection box 504 through the drop chute 506 under the guidance of the collection frame 501. When the shovel plate 304 is about to move into the collection frame 501, the guide rod 12 at the top of the shovel plate 304 can move into the inclined guide groove 11. At this time, the inclined guide groove 11 allows the shovel plate 304 to rotate to one side of the outer shell 1 through the guide rod 12. When the shovel plate 304 moves into the collection frame 501, the guide rod 12 moves out from the inside of the inclined guide groove 11. At the same time, the shovel plate 304 is inclined to contact the inner wall of the collection frame 501 under the elastic force of the torsion spring 306. The water pump 601 can extract the cleaning fluid inside the outer casing 1 through the extraction pipe 602. The extracted cleaning fluid flows into the inside of the diversion pipe 604 under the guidance of the transport pipe 603. Several rinsing nozzles 605 can rinse the shovel 304 that moves inside the collection frame 501. The contaminants adhering to the shovel 304 can be removed from the shovel 304 by the rinsing of the cleaning fluid. The removed contaminants flow into the inside of the collection box 504 under the drive of the cleaning fluid. The collection box 504 then filters out the contaminants, while the cleaning fluid falls back to the bottom of the outer casing 1.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
