Description

Technical Field

[0001] This utility model belongs to the field of automated curtain wall cleaning technology, and specifically relates to a cleaning device, a curtain wall cleaning robot and a collaborative system. Background Technology

[0002] Existing exterior wall cleaning robots typically use roller brushes for curtain wall cleaning. However, existing roller brushes generally have a fixed coverage width. This means that when cleaning curtain walls of different widths, operators must manually change to different roller brush sizes according to the actual dimensions of the curtain wall. This method is not only time-consuming and labor-intensive, but also significantly reduces overall work efficiency.

[0003] Specifically, in actual curtain wall cleaning operations, the width of curtain walls often varies, ranging from narrow window edges to wide glass curtain walls, each requiring different cleaning coverage areas. If the coverage width of the roller brush is fixed, it may cause unnecessary repeated cleaning or waste of resources when dealing with narrow curtain walls; while when dealing with wide curtain walls, multiple cleaning passes are required to achieve complete coverage, and blind spots may even occur. To solve this problem, current technology has to rely on manual roller brush replacement, which not only increases the preparation time for cleaning operations but also increases the complexity of operations, thus affecting the automation and intelligence level of the cleaning robot. This fixed-width roller brush design limits the adaptability and flexibility of exterior wall cleaning robots in different curtain wall environments, making it impossible for them to efficiently complete cleaning tasks in practical applications.

[0004] Therefore, existing technologies need to be improved and developed. Utility Model Content

The invention achieves adjustable cleaning coverage width, avoids the tedious operation of manually replacing the roller brush, and improves cleaning efficiency and adaptability.

[0041] Reference Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 This utility model provides a cleaning device, including a body, on which a roller brush section is provided. The roller brush section includes a roller brush 110, which includes a first connecting section 111 and a second connecting section 112. The first connecting section 111 is inserted into the second connecting section 112 and together with the second connecting section 112 forms a telescopic section that can extend and retract in the left and right direction. The surface of the first connecting section 111 is provided with multiple first bristles 1111 extending in the left and right direction, and the multiple first bristles 1111 are arranged circumferentially around the first connecting section 111. The surface of the second connecting section 112 is provided with multiple second bristles 1121 extending in the left and right direction, and the multiple second bristles 1121 are arranged circumferentially around the second connecting section 112. The first bristles 1111 and the second bristles 1121 are staggered, and the projection of any first bristle 1111 in the left and right direction falls between two adjacent corresponding second bristles 1121, so as to avoid the first bristles 1111 and the second bristles 1121 interfering with each other when the telescopic section retracts.

[0042] This application effectively solves the problem of fixed coverage width of traditional roller brushes by introducing a retractable roller brush design, significantly improving the efficiency and adaptability of cleaning operations.

[0043] The roller brush section mainly consists of a roller brush 110, which is the component that directly contacts the curtain wall for cleaning. The roller brush 110 is designed with a telescopic structure to accommodate curtain walls of different widths. This telescopic function is achieved through the insertion of a first connecting section 111 and a second connecting section 112. The first connecting section 111 and the second connecting section 112 together constitute the telescopic section of the roller brush 110, allowing the roller brush 110 to be adjusted in length in the left-right direction. Brush bristles are cleaning elements disposed on the surfaces of the first connecting section 111 and the second connecting section 112 for physically scrubbing the curtain wall surface.

[0044] Specifically, the body of the cleaning device is the main structure of the entire equipment, used to support and fix various functional components. A roller brush section is installed on the body, which is the core working unit of the cleaning device. The roller brush section includes a roller brush 110, which is the component that directly contacts the curtain wall for cleaning. The roller brush 110 can adopt various structural forms; for example, it can be composed of a single integral brush roller or a combination of multiple independent brush heads. As a preferred embodiment, the roller brush 110 is designed with a telescopic structure to adapt to curtain walls of different widths.

[0045] The roller brush 110 includes a first connecting section 111 and a second connecting section 112, which are connected by insertion to form a telescopic section capable of extending and retracting in the left-right direction. This telescopic section can be implemented manually, i.e., the operator manually stretches or contracts the roller brush 110 according to the width of the curtain wall; or it can be assisted by a mechanical structure, such as a gear rack, lead screw, or nut transmission mechanism to achieve the extension and retraction of the roller brush 110.

[0046] Furthermore, both the first connecting segment 111 and the second connecting segment 112 are provided with bristles. The material and density of the bristles can be selected according to cleaning requirements; for example, nylon bristles or PBT bristles can be used. The bristles can be fixed by methods such as embedding or bonding. To prevent interference between the bristles of the first connecting segment 111 and the second connecting segment 112 when the telescopic segment retracts, the first bristles 1111 and the second bristles 1121 are staggered. For example, when the first bristles 1111 move in the left-right direction, they can smoothly enter the gap between two adjacent second bristles 1121, so that when the roller brush 110 retracts, the bristles can avoid each other, preventing squeezing and damage. This staggered arrangement can be achieved by adjusting the embedding position of the bristles.

[0047] The cleaning device of this application effectively solves the problem of fixed coverage width of the roller brush in traditional curtain wall cleaning through its unique retractable roller brush design. When cleaning curtain walls of different widths, the first connecting section 111 and the second connecting section 112 of the roller brush 110 can extend and retract in the left and right directions, thereby adjusting the overall width of the roller brush 110 to accurately adapt to the actual width of the curtain wall. For example, when cleaning a narrower curtain wall area, the roller brush 110 can retract to avoid unnecessary repeated cleaning; while when cleaning a wider curtain wall area, the roller brush 110 can extend to ensure coverage of a larger area at once, reducing the number of repetitive cleaning operations.

[0048] During the extension and retraction of the roller brush 110, the bristles on the surfaces of the first connecting section 111 and the second connecting section 112 are arranged in a staggered manner, a design that is crucial. When the roller brush 110 retracts, if the bristles are not staggered, they will squeeze and interfere with each other, causing deformation, damage, and even affecting the normal extension and retraction function of the roller brush 110. Through this staggered arrangement, the bristles avoid each other when the roller brush 110 retracts, preventing physical interference and ensuring smooth extension and retraction of the roller brush 110 and the lifespan of the bristles. Therefore, the cleaning device of this application can flexibly adjust the cleaning range according to the actual width of the curtain wall, significantly improving the efficiency and adaptability of cleaning operations, while avoiding potential problems caused by bristle interference in traditional solutions.

[0049] The core innovation of this application lies in its retractable roller brush design and the staggered arrangement of the bristles. Compared to the closest prior art solution with a fixed roller brush coverage width, the cleaning device of this application has significant advantages. Traditional solutions require manual replacement of roller brushes of different specifications when dealing with curtain walls of different widths, which is not only time-consuming and labor-intensive but also reduces work efficiency. This application, by introducing the insertion of the first connecting section 111 and the second connecting section 112, allows the roller brush 110 to extend and retract in the left and right directions, thereby achieving adaptive adjustment of the cleaning width without the need for frequent roller brush replacements.

[0050] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 2 The roller brush also includes a first telescopic mechanism, which is connected to the roller brush 110 and is used to drive the roller brush 110 to move back and forth in the front and back direction to adapt to cleaning curtain walls of different depths.

[0051] Specifically, the first telescopic mechanism can be understood as a drive mechanism capable of providing linear displacement, such as an electric push rod, pneumatic cylinder, hydraulic cylinder, gear and rack mechanism, or lead screw and nut mechanism. Its purpose is to adapt to different depths of curtain wall cleaning requirements by changing the front-to-back position of the roller brush 110 relative to the machine body. In practical applications, the first telescopic mechanism can be fixed to the machine body and connected to the bracket or body of the roller brush 110 via a connector, thereby precisely controlling the front-to-back movement distance and position of the roller brush 110 upon receiving control commands.

[0052] The solution of this application adds a first telescopic mechanism to the roller brush section and connects it to the roller brush 110. This allows the roller brush 110 to not only extend and retract in the left and right directions to adapt to width changes, but also to reciprocate in the front and back directions. Because the first telescopic mechanism can precisely control the front and back position of the roller brush 110, the cleaning device can adjust the extension or retraction distance of the roller brush 110 when dealing with curtain walls of different depths, ensuring that the roller brush 110 always maintains optimal contact pressure and angle against the curtain wall surface, thereby achieving effective cleaning of curtain walls of various depths.

[0053] Through the above technical solution, the roller brush of the cleaning device has the ability to move in the front and back directions, effectively solving the problem of poor adaptability of traditional cleaning devices when cleaning curtain walls of different depths. The introduction of the first telescopic mechanism allows the roller brush 110 to be precisely adjusted according to the actual depth of the curtain wall, avoiding cleaning blind spots or poor cleaning effect caused by depth mismatch, and significantly improving the versatility and cleaning efficiency of the cleaning device.

[0054] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 2 The first telescopic mechanism includes two sets of translation devices 210. Each translation device 210 includes a rack 211 and a slide rail 212 arranged parallel to the rack 211. One end of the rack 211 is fixedly connected to the roller brush 110 and slidably connected to the corresponding slide rail 212 through a slider 213. The traditional solution only has a rack 211 and does not have a slide rail 212. The rack in the traditional solution forms a cantilever structure, which cannot guarantee the stability of driving the roller brush 110 to move back and forth. In particular, when the roller brush 110 is used for curtain wall cleaning, it often needs to be pressed tightly against the curtain wall with a certain pressure to achieve a good cleaning effect. The cantilever structure cannot provide stable pressure control. The solution of this application adds a slide rail 212 and forms a parallelogram structure with the rack 211 through a slider 213 (the other end of the rack 211 is also connected to the slide rail 212), which greatly improves the stability.

[0055] Specifically, the aforementioned first telescopic mechanism is designed to include two sets of translation devices 210 to ensure stable support and drive for the roller brush 110. Each set of translation devices 210 consists of a rack 211 and a slide rail 212 arranged parallel to it. One end of the rack 211 is fixedly connected to the roller brush 110, while a slider 213 is mounted on the rack 211 and can slide with the corresponding slide rail 212. This configuration allows the rack 211 and the slide rail 212 to form a parallelogram structure through the slider 213, thereby providing stable support and guidance for the forward and backward movement of the roller brush 110.

[0056] The solution proposed in this application solves the problem of insufficient stability of the traditional cantilever rack 211 when driving the roller brush 110 to move back and forth. This is because a parallel rail 212 is set parallel to the rack 211, and a slider 213 is used to connect the rack 211 and the rail 212, thus constructing a parallelogram structure. This parallelogram structure ensures that the roller brush 110 maintains a stable posture when moving in the back-and-forth direction, avoiding the swaying or tilting that is prone to occur in traditional cantilever structures under stress. When the roller brush 110 needs to be pressed firmly against the curtain wall for cleaning, this parallelogram structure provides uniform and stable support, ensuring a constant contact pressure between the roller brush 110 and the curtain wall, thereby guaranteeing the uniformity and reliability of the cleaning effect.

[0057] By adding the slide rail 212 and forming a parallelogram structure with the slider 213 and rack 211, the stability of the roller brush 110 during its forward and backward movement is significantly improved. Compared with the traditional solution that only uses a cantilever rack 211, the solution of this application can better ensure the close contact between the roller brush 110 and the curtain wall during cleaning operations and provide stable pressure control, thereby effectively avoiding the problems of incomplete cleaning or uneven cleaning effect caused by insufficient stability, and thus ensuring the high efficiency and high quality of the cleaning operation.

[0058] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 2 The racks 211 of the two sets of translation devices 210 are meshed with the same drive shaft 220. The drive shaft 220 is connected to the first drive device 230. The first drive device 230 is used to drive the drive shaft 220 so that the racks 211 of the two sets of translation devices 210 move synchronously, thereby preventing the roller brush 110 from tilting and ensuring that the roller brush 110 is horizontally and tightly attached to the curtain wall, thus ensuring the cleaning effect.

[0059] Specifically, the aforementioned drive shaft 220 can be understood as a horizontally arranged rotating shaft, with its two ends or middle position respectively meshing with the racks 211 of the two sets of translation devices 210. The meshing connection can be achieved through the cooperation of gears and racks, ensuring that the rotation of the drive shaft 220 can directly drive the linear movement of the racks 211. The first drive device 230 can be a motor, such as a stepper motor or a servo motor, whose output shaft is directly connected to the drive shaft 220 or through a reduction mechanism. The first drive device 230 achieves synchronous drive of the two sets of racks 211 by precisely controlling the rotation of the drive shaft 220.

[0060] The solution of this application ensures absolute synchronization of the two sets of racks 211 during movement by meshing the racks 211 of the two sets of translation devices 210 with the same drive shaft 220, and driving the drive shaft 220 uniformly by a first drive device 230. Since the moving distance and speed of the two sets of racks 211 remain consistent, the two ends of the roller brush 110 connected to the racks 211 can move back and forth at the same pace, effectively avoiding tilting of the roller brush 110 due to uneven force or asynchronous driving during its forward and backward movement. Therefore, the roller brush 110 can always remain horizontal and adhere tightly to the curtain wall surface with stable pressure.

[0061] Through the above technical solution, this application can effectively solve the problem of tilting that may occur during the forward and backward movement of the roller brush 110. Because the racks 211 of the two sets of translation devices 210 are forced to move synchronously, the roller brush 110 always maintains a horizontal posture, thus ensuring that the roller brush 110 can be evenly and stably pressed against the curtain wall. This not only improves the stability of the cleaning operation, but more importantly, it ensures the uniformity of the contact pressure between the roller brush 110 and the curtain wall, thereby significantly improving the thoroughness and consistency of the cleaning, avoiding localized unclean or missed areas caused by roller brush tilting, and thus ensuring the overall cleaning effect.

[0062] In some embodiments, reference is made to the appendix. Figure 5 and attached Figure 6 The machine body is also equipped with a wiping unit, which includes a fixing frame 310 and a wiping strip 320. The fixing frame 310 is connected to the machine body through a hole shaft so that the fixing frame 310 can swing left and right relative to the machine body. The wiping strip 320 is connected to the fixing frame 310 through a hole shaft so that the wiping strip 320 can swing left and right relative to the fixing frame 310. The multi-level adaptive adjustment of the swing can ensure that the wiping strip 320 is horizontally and tightly attached to the curtain wall, thereby ensuring the cleaning effect.

[0063] Specifically, the squeegee is configured to scrape water off the curtain wall surface after the roller brush has completed its cleaning operation. The mounting bracket 310 is connected to the machine body via a perforated shaft, meaning the bracket 310 can swing at a certain angle horizontally around this shaft. This swinging capability allows the squeegee to adapt to slight unevenness on the curtain wall surface or changes in the cleaning device's posture during movement. Furthermore, the squeegee strip 320 is also connected to the mounting bracket 310 via a perforated shaft, allowing the squeegee strip 320 to swing left and right relative to the mounting bracket 310. This two-stage (mounted bracket 310 relative to the machine body, squeegee strip 320 relative to the mounting bracket 310) swing adjustment mechanism provides the squeegee strip 320 with greater adaptability. The squeegee strip 320 is typically made of a material with a certain degree of elasticity, such as rubber or silicone, with its edges contacting the curtain wall surface to scrape away liquid. The perforated shaft connection can be understood as a rotational connection achieved through structures such as pins or pivots, allowing the components to rotate freely within a certain range.

[0064] This application's solution effectively solves the problem of residual liquid after curtain wall cleaning by incorporating a squeegee unit on the machine body and introducing a two-stage hole-shaft connection swing mechanism between the fixing frame 310 and the squeegee strip 320 within the squeegee unit. When the cleaning device moves on the curtain wall, even if there are local unevenness on the curtain wall surface or slight changes in the posture of the cleaning device, the fixing frame 310 can first swing left and right through its hole-shaft connection with the machine body to perform initial posture adjustment of the squeegee unit. Based on this, the squeegee strip 320 then swings left and right a second time through its hole-shaft connection with the fixing frame 310, achieving more precise adaptive adjustment. This multi-stage adaptive adjustment swing mechanism ensures that the squeegee strip 320 always maintains a suitable angle and pressure in close contact with the curtain wall surface, thereby efficiently removing residual water stains and cleaning fluid after cleaning and avoiding problems such as incomplete squeegee removal or watermarks caused by poor contact between the squeegee strip 320 and the curtain wall.

[0065] Through the above technical solution, after completing the roller brush cleaning, the cleaning device can efficiently scrape water off the curtain wall surface using the squeegee. In particular, the adaptive oscillation capability achieved by the two-stage hole shaft connection between the fixing bracket 310 and the squeegee 320 significantly improves the fit between the squeegee 320 and the curtain wall surface. This not only ensures the complete removal of residual liquid, preventing water stains and dirt, but also ensures that the squeegee 320 maintains a stable scraping effect even on complex curtain wall structures or uneven surfaces during the cleaning process, thereby greatly improving the cleanliness and overall aesthetics of the curtain wall after cleaning.

[0066] In some embodiments, reference is made to the appendix. Figure 5The wiping unit includes two wiping strips 320, which are slidably mounted on the fixed frame 310 and staggered so that the two wiping strips 320 can change the coverage width in the left and right directions by reciprocating in the left and right directions.

[0067] Specifically, the two wiper blades 320 are designed to slide independently or synchronously on the mounting bracket 310 in the left-right direction. This sliding arrangement can be achieved by providing guide rails or grooves on the mounting bracket 310, with the wiper blades 320 engaging with the guide rails or grooves via corresponding sliders or connectors. The sliding of the wiper blades 320 can be controlled by an independent drive mechanism (e.g., a stepper motor, a lead screw drive mechanism, or a rack and pinion mechanism) to achieve precise displacement adjustment. Furthermore, the two wiper blades 320 are staggered, meaning they are not perfectly aligned initially, but rather have a certain offset or partial overlap. This staggered arrangement aims to ensure finer coverage width adjustment during the reciprocating movement of the wiper blades 320 and to avoid wiping blind spots in certain positions. For example, when the two wiper blades 320 move inward, the overlapping area can be increased, reducing the overall coverage width; when they move outward, the overlapping area can be reduced or they can be separated, thereby increasing the overall coverage width. In this way, the wiping unit can flexibly adjust its wiping coverage in the left and right directions according to actual cleaning needs.

[0068] The solution in this application configures the wiping unit to include two sliding and staggered wiping strips 320, thus making the left and right coverage width of the wiping strips 320 no longer fixed. When the cleaning device moves on the curtain wall, the two wiping strips 320 can be controlled to reciprocate in the left and right direction via a drive mechanism, depending on the actual width of the curtain wall, corners, or obstacles. For example, when cleaning a narrower area, the two wiping strips 320 can slide inwards, increasing the overlap and thus reducing the effective wiping width; while when cleaning a wider area, the two wiping strips 320 can slide outwards, reducing the overlap or separating them, thus increasing the effective wiping width. This dynamic adjustment capability allows the wiping unit to better adapt to curtain wall areas of different sizes and shapes, ensuring the comprehensiveness and efficiency of the wiping operation.

[0069] Through the above technical solution, the squeegee of this application can flexibly adjust the squeegee coverage width, effectively solving the problem of limited coverage when a single squeegee strip faces curtain walls of different widths. This not only improves the adaptability and flexibility of squeegee operations and avoids incomplete cleaning due to insufficient coverage, but also significantly improves overall cleaning efficiency and effectiveness by optimizing the squeegee path and reducing repetitive work. Especially when cleaning curtain walls with complex structures or irregular shapes, this solution ensures that the squeegee strip 320 always operates with the optimal coverage width, thereby guaranteeing the cleanliness of the curtain wall after cleaning.

[0070] In some embodiments, reference is made to the appendix. Figure 6 and attached Figure 7 The wiper unit includes a vacuum pump 330 and a suction chamber 340 connected to the vacuum pump 330. The wiper strip 320 is located on the upper edge of the suction chamber 340, and a water-blocking strip 350 is provided on the lower edge of the suction chamber 340. The water-blocking strip 350 is used to collect the liquid scraped off by the wiper strip 320 and guide it into the suction chamber 340.

[0071] Specifically, the vacuum pump 330 refers to a device capable of generating negative pressure. Its function is to create negative pressure inside the suction chamber 340 through suction, thereby drawing away the liquid within the suction chamber 340. In practical applications, the vacuum pump 330 can be any commercially available miniature vacuum pump or industrial vacuum pump. Its selection should be based on a comprehensive consideration of factors such as the overall size of the cleaning device, the required suction efficiency, and power consumption. The suction chamber 340 can be understood as a closed or semi-closed space used to temporarily store and guide the scraped liquid. The suction chamber 340 is typically designed to match the width of the wiper blade 320 to ensure effective collection of all liquid scraped by the wiper blade 320. The material of the suction chamber 340 can be a corrosion-resistant and easy-to-clean material, such as engineering plastics or stainless steel. The wiper blade 320 is located at the upper edge of the suction chamber 340, meaning that during wiping operations, the edge of the wiper blade 320 is in close contact with the curtain wall surface, while its lower area connects to the inlet of the suction chamber 340. This layout ensures that liquid scraped by the squeegee 320 can fall directly into or be guided into the suction chamber 340. A water-blocking strip 350 is positioned along the lower edge of the suction chamber 340. Its main function is to form a physical barrier to collect liquid scraped from the squeegee 320 and flowing into the suction chamber 340, preventing it from dripping or overflowing directly into the suction chamber 340 under gravity. Instead, it guides the liquid into the suction chamber 340 for extraction by the vacuum pump 330. The water-blocking strip 350 is typically made of flexible materials, such as rubber or silicone, to accommodate slight unevenness on the curtain wall surface and ensure effective liquid collection and diversion.

[0072] This application's solution establishes a highly efficient liquid collection and removal system by incorporating a vacuum pump 330, a suction chamber 340, and a water-blocking strip 350 into the squeegee unit. When the squeegee 320 moves across the curtain wall surface and scrapes off liquid, the liquid flows down its surface and is effectively collected and guided by the water-blocking strip 350 located at the lower edge of the suction chamber 340. The design of the water-blocking strip 350 ensures that the liquid does not drip directly but is guided into the suction chamber 340. Simultaneously, the vacuum pump 330 continuously operates, generating negative pressure within the suction chamber 340, thereby rapidly drawing away the liquid entering the suction chamber 340 and transporting it through pipelines to a recovery container or for further treatment. This collaborative mechanism ensures that liquid on the curtain wall surface is thoroughly removed after squeegeeing, preventing liquid residue and secondary pollution.

[0073] Through the above technical solution, this application effectively solves the problems of incomplete liquid collection, liquid residue, and secondary pollution caused by traditional squeegee devices. The synergistic effect of the squeegee strip 320, suction chamber 340, water-blocking strip 350, and vacuum pump 330 ensures that the scraped liquid can be collected and removed quickly and efficiently, thereby significantly improving the overall cleaning effect and work efficiency of the cleaning device, avoiding water stains, and making the surface of the curtain wall cleaner after cleaning.

[0074] In some embodiments, reference is made to the appendix. Figure 5 The squeegee also includes a second telescopic mechanism, which is connected to the fixed frame and is used to drive the squeegee strip 320 to reciprocate in the front-back direction via the fixed frame, so as to adapt to cleaning curtain walls of different depths.

[0075] Specifically, the second telescopic mechanism is configured to connect to the fixed frame 310. This second telescopic mechanism drives the fixed frame 310, which in turn drives the wiper strip 320 connected to the fixed frame 310 to reciprocate in the front-to-back direction. This reciprocating movement in the front-to-back direction allows the wiper strip 320 to flexibly adapt to curtain wall surfaces of different depths. For example, when there is a recessed area on the curtain wall surface, the second telescopic mechanism can drive the wiper strip 320 to extend forward to ensure that the wiper strip 320 fits tightly against the surface of the recessed area; conversely, when there is a raised area on the curtain wall surface, the second telescopic mechanism can drive the wiper strip 320 to retract backward to avoid excessive compression or interference between the wiper strip 320 and the raised area. The second telescopic mechanism can be implemented in various ways, such as a motor-driven lead screw mechanism, a rack and pinion mechanism, or a hydraulic / pneumatic telescopic mechanism, the core of which is to provide stable and controllable front-to-back displacement.

[0076] The solution in this application adds a second telescopic mechanism to the wiping section, enabling the wiping strip 320 to adapt not only to changes in the horizontal position of the curtain wall via the left-right swing of the mounting bracket 310, but also to reciprocate along the front-back direction via the second telescopic mechanism, thereby adapting to changes in the curtain wall's depth. When the cleaning device moves along the curtain wall, if a change in curtain wall depth is detected, the second telescopic mechanism adjusts the position of the wiping strip 320 in the front-back direction according to a preset control strategy or real-time feedback information. This bidirectional (left-right swing and front-back extension) adaptive adjustment capability ensures that the wiping strip 320 can always adhere tightly to the curtain wall surface with appropriate pressure and angle, regardless of the complexity of the curtain wall's shape or changes in depth.

[0077] Through the above technical solution, the squeegee unit gains the ability to move back and forth in the front-to-back direction, greatly enhancing the adaptability of the squeegee strip 320 to curtain walls of different depths. This allows the squeegee strip 320 to effectively cover and scrape away liquid from all areas of the curtain wall, avoiding problems such as incomplete squeegeeing or damage to the squeegee strip 320 due to depth differences. As a result, the squeegeeing effect of the cleaning device is significantly improved, ensuring the cleanliness and dryness of the curtain wall after cleaning, thereby improving the efficiency and quality of the overall cleaning operation.

[0078] In some embodiments, reference is made to the appendix. Figure 8 The machine body is also equipped with a spray section, which includes a main control shaft 410 and two spray bars 420. The two spray bars 420 are slidably mounted on the main control shaft 410 and staggered so that the two spray bars 420 can change the coverage width in the left and right directions by reciprocating along the left and right directions.

[0079] Specifically, the spray unit is a component used to spray liquids (such as water, cleaning agents, etc.) onto the curtain wall surface. The main control shaft 410 can be understood as the support and guide structure for the spray strips 420; it is typically rod-shaped or tubular and fixedly mounted on the machine body. The two spray strips 420 are mounted on the main control shaft 410 via a sliding connection, meaning that the spray strips 420 can move freely along the axial direction (i.e., left-right direction) of the main control shaft 410. The "staggered arrangement" of the spray strips 420 means that the two spray strips 420 do not completely overlap, but rather have a certain interval or overlap, allowing them to cover a wider area or achieve more precise coverage adjustment during movement. By moving the two spray strips 420 back and forth in the left-right direction, the coverage width of the spray can be effectively changed. For example, when the two spray strips 420 move closer together, the coverage width decreases; when they separate to the sides, the coverage width increases. This design aims to provide flexible spray range adjustment capabilities to adapt to cleaning areas of different widths or shapes.

[0080] This application's solution addresses the lack of liquid spraying functionality in basic cleaning solutions by adding a spray unit to the body of the cleaning device. Specifically, the main control shaft 410 of the spray unit provides a stable mounting and guiding platform for the spray strips 420. Two spray strips 420 are slidably mounted on the main control shaft 410 and staggered, allowing them to cover a certain area initially. When the spray coverage width needs adjustment, a drive mechanism (e.g., a stepper motor and transmission mechanism) causes the spray strips 420 to reciprocate along the left-right direction of the main control shaft 410. This movement allows the spray strips 420 to dynamically change their spray range in the left-right direction according to actual cleaning needs. For example, when cleaning a narrow area, the spray strips 420 can retract inward to avoid liquid waste; when cleaning a wider area, they can extend outward to ensure full coverage. Thus, this spray unit can effectively perform pre-wetting, spraying cleaning agents, or rinsing operations, providing a good foundation for subsequent roller brush cleaning, or rinsing after cleaning, thereby significantly improving the overall cleaning effect.

[0081] Through the above technical solution, the cleaning device of this application can achieve flexible liquid spraying on the curtain wall surface, making up for the shortcomings of relying solely on physical cleaning with roller brushes. In particular, by having two spray strips 420 slide and staggered on the main control shaft 410 and move back and forth in the left and right directions, the spray coverage width can be precisely adjusted according to the actual width of the curtain wall or the needs of the cleaning area. This not only avoids waste of liquid spraying and improves the utilization efficiency of cleaning agents, but also ensures comprehensive and effective spraying of curtain walls of different sizes, thereby creating favorable conditions for subsequent cleaning operations, significantly improving the thoroughness and efficiency of cleaning, and ultimately ensuring the cleanliness of the curtain wall.

[0082] In some embodiments, reference is made to the appendix. Figure 8 The spray unit also includes a second drive device 430, which is connected to the main control shaft 410 and is used to drive the main control shaft 410 to rotate so that the spray bar 420 swings up and down, thereby spraying the dead corners of the curtain wall more effectively.

[0083] Specifically, the second drive device 430 can be understood as a mechanism that provides rotational power to drive the main control shaft 410 to rotate. In practical applications, the second drive device 430 can be a motor, such as a stepper motor or a servo motor, connected to the main control shaft 410 through a reduction mechanism. The rotation of the main control shaft 410 will directly drive the spray strips 420 mounted on it to swing up and down. "Swinging up and down" means that the spray strips 420 can rotate around the axis of the main control shaft 410 at a certain angle, thereby changing the vertical spray angle of the spray liquid or the vertical position of the spray strips 420. This swinging capability allows the spray strips 420 to adapt to curtain wall areas of different heights and depths, especially those dead corners that are difficult to reach with traditional fixed-angle spraying.

[0084] The solution proposed in this application solves the problem of ineffective spraying of curtain wall corners by relying solely on the left-right movement of the spray bar 420. Specifically, when the second drive device 430 drives the main control shaft 410 to rotate, the spray bar 420, which is fixed or slidably mounted on the main control shaft 410, swings up and down. This up-and-down swing allows adjustment of the spray angle or vertical position of the spray bar 420, enabling the cleaning fluid to be sprayed onto traditionally difficult-to-clean areas such as the top edge, bottom recesses, and inner sides of window frames. It is precisely because the spray bar 420 gains vertical flexibility that the cleaning device can achieve more comprehensive and thorough spraying coverage of the curtain wall.

[0085] Through the above technical solution, the spray section of the cleaning device can not only adjust the coverage width by moving the spray strips 420 left and right, but also drive the main control shaft 410 to rotate via the second drive device 430, thereby achieving the up-and-down swing of the spray strips 420. This multi-dimensional spray angle adjustment capability significantly improves the adaptability of the cleaning device to complex curtain wall structures, ensuring that the cleaning fluid can be accurately and effectively sprayed to every corner of the curtain wall, especially those easily overlooked dead corner areas, thus greatly improving the overall cleaning effect and cleanliness of the curtain wall.

[0086] In some embodiments, reference is made to the appendix. Figure 8 The spray bar 420 is provided with a rotatable baffle plate 440 at its end. The baffle plate 440 is used to block the liquid sprayed from the left and right ends of the spray bar 420 and can rotate to the back side of the spray bar 420, thereby avoiding interference between the baffle plate 440 and the corner of the curtain wall, which would cause the spray bar 420 to be obstructed and thus affect cleaning.

[0087] Specifically, rotatable baffles 440 are positioned at both ends of the spray bar 420. Their main function is to effectively block liquid sprayed from both ends of the spray bar 420 during normal spraying operations, preventing liquid from splashing onto non-cleaning areas and pedestrians, or causing unnecessary waste. The baffle 440 can be understood as a structural component capable of rotating around its own axis or connection point. Its rotation mechanism (not shown) may include, but is not limited to, a pivot, hinge, or rotating joint. In practical applications, when the spray bar 420 moves to the vicinity of a corner of the curtain wall, the baffle 440 can be driven to rotate to the back side of the spray bar 420, i.e., the side away from the curtain wall. For example, the baffle 440 can be configured to detect an obstacle via a sensor when it comes into contact with or approaches the curtain wall, and then be rotated and retracted by a drive mechanism (such as a small motor or linkage mechanism). The purpose is to reduce the overall width or protrusion of the end of the spray bar 420 by rotating the water baffle 440 to the back side, thereby avoiding physical interference or collision between the water baffle 440 and the corner of the curtain wall.

[0088] The solution proposed in this application effectively solves the interference problem that the spray strip 420 may encounter when cleaning the corners of the curtain wall by setting a rotatable baffle 440 at the end of the spray strip 420. It is precisely because the baffle 440 has a rotatable characteristic that it can unfold and function when it is necessary to block liquid splashing, and can rotate and retract to the back of the spray strip 420 when approaching narrow areas such as curtain wall corners. This design allows the end of the spray strip 420 to adapt more flexibly to complex curtain wall structures when moving left and right, avoiding collisions or jamming caused by fixed baffle structures, thus ensuring smooth movement of the spray strip 420 and effective coverage of blind spots in the curtain wall.

[0089] Through the above technical solution, this application can significantly improve the adaptability and efficiency of the cleaning device when cleaning the corners or edges of curtain walls. Because the baffle plate 440 can rotate according to actual operational needs, interference with the corner positions of the curtain wall is avoided, thus ensuring that the spray strip 420 can move unimpeded to the predetermined position, achieving comprehensive spraying of the curtain wall's dead corners, thereby guaranteeing the uniformity and thoroughness of the overall cleaning effect. Furthermore, this solution also helps protect the spray strip 420 and its associated structures from impact damage, extending the service life of the equipment.

[0090] Reference Appendix Figure 9 This utility model provides a curtain wall cleaning robot, including the cleaning device in the above embodiments.

[0091] Specifically, a curtain wall cleaning robot is an automated device capable of autonomously or semi-autonomously moving across the surface of a curtain wall and performing cleaning operations. Its core lies in integrating the aforementioned cleaning device as a functional module into the robot body, allowing the cleaning device to move and position along with the robot body on the curtain wall surface, thereby achieving cleaning of different areas of the curtain wall. The detailed structure and function of the cleaning device have been described in the above embodiments, and it includes key components such as the body, roller brush, squeegee, and sprayer. These components work together to complete the cleaning, squeegeeing, and spraying operations of the curtain wall.

[0092] The solution proposed in this application integrates the aforementioned cleaning device into a curtain wall cleaning robot, eliminating the need for direct manual operation or deployment of large auxiliary equipment. The curtain wall cleaning robot can autonomously move across the curtain wall surface, bringing the cleaning device to the area requiring cleaning and ensuring it operates close to the surface. This allows components such as the roller brush 110, squeegee 320, and spray strip 420 to effectively contact the curtain wall, performing cleaning, squeegeeing, and spraying functions. This integration significantly improves the automation and efficiency of the cleaning operation while avoiding the safety risks associated with working at heights, making it particularly suitable for the maintenance of high-rise building curtain walls.

[0093] Through the above technical solution, the curtain wall cleaning robot of this application can achieve automated and efficient cleaning of curtain walls. Compared with traditional manual cleaning or cleaning methods relying on large mechanical assistance, this robot significantly reduces labor costs and operational risks, especially demonstrating unique advantages in high-rise curtain wall cleaning. The integration of the cleaning device makes the entire cleaning process smoother and more continuous, improving the overall efficiency and safety of the cleaning operation, while ensuring the stability and consistency of the cleaning effect.

[0094] In some embodiments, reference is made to the appendix. Figure 5 and attached Figure 9 The curtain wall cleaning robot also includes a robot body and ducted fans 500 arranged on the left and right sides of the robot body. The ducted fans 500 are used to adjust the left and right offset of the cleaning device by changing the left and right position of the robot body.

[0095] Specifically, the robot body refers to the core structure that carries the cleaning device and other related components. It can be a frame, a box, or other structure suitable for movement and operation on the curtain wall. The ducted fan 500 can be understood as an axial flow fan with a shroud, which generates thrust or suction to move or adjust the robot body horizontally. The ducted fans 500 are arranged on the left and right sides of the robot body, meaning there are at least two ducted fans 500, located on the left and right sides of the robot body respectively. The ducted fans 500 are used to adjust the lateral offset of the cleaning device by changing the left and right position of the robot body. This means that by controlling the difference in thrust or suction between the left and right ducted fans 500, the robot body can move laterally, thereby causing the cleaning device mounted on it to make precise left and right offset adjustments. For example, when the thrust of the left ducted fan 500 is greater than that of the right ducted fan 500, the robot body will move to the right, and vice versa. The purpose is to ensure that the cleaning device can accurately cover the cleaning area of ​​the curtain wall, avoiding omissions or repeated cleaning.

[0096] This application's solution addresses the problem of inaccurate or inflexible left-right position adjustment of the cleaning device in traditional curtain wall cleaning robots by incorporating a robot body and ducted fans 500 positioned on either side of the robot body. Specifically, the ducted fans 500 generate controllable airflow thrust or suction, enabling precise left-right adjustments to the robot body. When a leftward shift is required, the thrust of the right ducted fan 500 can be increased or the thrust of the left ducted fan 500 decreased; conversely, a rightward shift can be achieved by increasing the thrust of the left ducted fan 500 or decreasing the thrust of the right ducted fan 500. This differentiated thrust control allows for precise lateral movement of the robot body, thereby driving accurate left-right adjustments to the cleaning device.

[0097] Through the above technical solutions, the curtain wall cleaning robot can achieve precise and flexible adjustment of the cleaning device in the left and right directions. This not only improves the coverage and efficiency of the cleaning operation, avoids cleaning dead spots and repeated cleaning, but also enables the robot to better adapt to changes in the curtain wall structure and the planning of the cleaning path, thereby significantly improving the overall effect and intelligence level of curtain wall cleaning.

[0098] Reference Appendix Figure 10 This utility model provides a collaborative system, including the curtain wall cleaning robot 600 in the above embodiments.

[0099] In some embodiments, reference is made to the appendix. Figure 10The collaborative system also includes a water treatment unit 700, which is connected to the curtain wall cleaning robot 600 and is used to supply liquids to the curtain wall cleaning robot 600. The liquids include tap water, detergent, and pure water. Each liquid is controlled by an independent control valve. When cleaning the curtain wall, the curtain wall cleaning robot 600 mainly sprays detergent as it climbs up from the ground. When the curtain wall cleaning robot 600 descends, it sprays tap water or pure water. Since tap water often contains impurities, the water treatment unit 700 produces pure water through an ultrafiltration device, which can further improve the cleanliness of the curtain wall after cleaning.

[0100] Specifically, the integrated water treatment unit 700 can be understood as a device that integrates liquid storage, treatment, and supply functions. As a specific implementation, the integrated water treatment unit 700 may include multiple independent storage tanks for storing tap water, detergent concentrate, and purified water, respectively. For example, the detergent concentrate can be stored in a separate container and supplied after being diluted and mixed with tap water in a specific ratio using a metering pump when needed. Liquid transfer between the integrated water treatment unit 700 and the curtain wall cleaning robot 600 is achieved through connecting pipelines; for example, high-pressure hoses and quick connectors can be used to ensure the stability and sealing of the liquid during transmission.

[0101] The control of the liquid supply is achieved through independent control valves. Specifically, each liquid (tap water, detergent, purified water) has its own independent control valve, such as a solenoid valve or an electric ball valve, on its supply line. These control valves can be centrally managed by the collaborative system's control unit, precisely opening, closing, and regulating the flow rate according to preset cleaning programs or operator instructions. For example, in some implementations, the control valves can also be manually operated, switched by on-site personnel as needed.

[0102] This application also optimizes the liquid spraying strategy during the cleaning process. Specifically, when the curtain wall cleaning robot 600 ascends from the ground, it primarily sprays detergent. This ascent can be determined by the robot's position sensor or altimeter, triggering the detergent spraying. For example, the detergent can be sprayed from the robot's built-in spray unit or directly delivered to the nozzles on the robot via a high-pressure pump from the integrated water treatment unit 700. When the curtain wall cleaning robot 600 descends, it sprays tap water or purified water. Similarly, the robot's descent can be detected by sensors, and the spraying mode can be switched to tap water or purified water based on a preset program or operator selection. For example, in some cases, to save costs, tap water can be used for initial rinsing; while in situations requiring extremely high cleanliness, purified water will be used for final rinsing.

[0103] Furthermore, the integrated water treatment unit 700 is equipped with an ultrafiltration device to treat tap water into pure water. The ultrafiltration device may include an ultrafiltration membrane module, a booster pump, and a pre-filter. For example, tap water first passes through a pre-filter to remove large particulate impurities, and then is pumped into the ultrafiltration membrane module. The ultrafiltration membrane removes colloids, bacteria, viruses, and other impurities from the water through physical retention, thus obtaining high-purity water. The purpose is that tap water often contains mineral impurities such as calcium and magnesium ions, which can easily leave water stains on the curtain wall surface after drying, affecting the cleaning effect. Producing pure water through ultrafiltration effectively avoids water stains, thereby further improving the cleanliness of the curtain wall after cleaning and achieving a more perfect cleaning effect.

[0104] This application's collaborative system, building upon existing curtain wall cleaning technologies, significantly enhances the automation level and final cleaning effect by introducing a water treatment integrated machine 700 and its intelligent liquid supply strategy. Traditional cleaning solutions often rely on a single water source or manually prepared cleaning solutions, which are not only inefficient but also difficult to guarantee cleaning quality, especially when water quality is poor, easily leaving water stains. This application, through the water treatment integrated machine 700, achieves on-demand supply of tap water, detergent, and purified water, and intelligently switches the sprayed liquid according to the robot's climbing and descending operation stages, effectively solving the problems of crude liquid management and unstable cleaning results in traditional solutions. In particular, the water treatment integrated machine 700 produces purified water through an ultrafiltration device, completely avoiding impurities in tap water from leaving water stains on the curtain wall, thereby significantly improving the cleanliness after cleaning and achieving more efficient, thorough, and intelligent curtain wall cleaning operations, further enhancing the overall performance of the cleaning robot and the user experience.
