Description

Technical Field

[0001] This invention relates to the field of intelligent cleaning technology, specifically to a modular guide rail type high-rise window cleaning system. Background Technology

[0002] Currently, cleaning high-rise windows mainly relies on manual suspended platforms or "spider-men" performing high-altitude operations, which poses extremely high safety risks and is inefficient and costly. Although some automated window cleaning robots have emerged on the market, most are suction-type or wheeled, which have limited applicability (e.g., cannot be used on frameless glass or certain special glass), inaccurate movement paths, easy detachment, insufficient cleaning coverage, and uneven pressure applied to the glass, which may cause scratches. Existing automated window cleaning solutions usually integrate water supply pipelines into the moving cleaning head, resulting in complex wiring structures, high failure rates, and inconvenient maintenance. Furthermore, existing automation solutions typically lack integrated fluid supply and wastewater collection functions, and the cleaning process still requires manual intervention, failing to achieve truly fully automated closed-loop management.

[0003] Therefore, there is an urgent need to provide a modular guide rail-type high-rise window cleaning system to solve the above problems. Summary of the Invention

[0022] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0023] The present invention proposes a modular guide rail type high-rise window cleaning system.

[0024] Reference Figures 1 to 5 In this embodiment, it includes: The guide rail module is installed on the side of the window 1 frame and includes at least one guide rail 2 extending along the height direction of the window 1; The cleaning head assembly 3 is slidably connected to the guide rail 2 and includes an elastic clamping mechanism 31 and a modular cleaning assembly. The modular cleaning assembly is detachably connected to the elastic clamping mechanism 31, which is used to press the modular assembly against the surface of the window 1. The drive system includes a first drive mechanism 41 and a second drive mechanism 42. The first drive mechanism 41 is drively connected to the second drive mechanism 42 to drive the second drive mechanism 42 to move up and down along the guide rail 2. The second drive mechanism 42 is used to drive the cleaning head assembly 3 to move laterally in a direction parallel to the plane of the window 1. The fluid supply unit includes a cleaning water tank 51 and a spraying unit 52; the spraying unit 52 is located at the top of the window 1 and connected to the cleaning water tank 51 via a pipe 53, and is used to spray cleaning fluid onto the surface of the window 1. The control unit, located indoors, is electrically connected to the cleaning head assembly 3, the drive system, and the fluid supply unit. The water collection unit, located at the bottom of window 1, is used to collect the wastewater after cleaning.

[0025] In this embodiment, the cleaning system includes a guide rail module, a cleaning head assembly 3, a drive system, a fluid supply unit, a control unit, and a water collection unit. The guide rail module is installed on the left and right sides or one side of the window 1 frame and includes at least one guide rail 2 extending along the height direction of the window 1. The rail can be made of high-strength aluminum alloy profile to ensure the stability of the guide rail. The cleaning head assembly 3 is slidably connected to the guide rail 2 and includes an elastic clamping mechanism 31 and a modular cleaning component. The modular cleaning component can be quickly and detachably installed at the front end of the elastic clamping mechanism 31. During cleaning operations, the elastic clamping mechanism 31... The modular cleaning components are pressed evenly and controllably onto the glass surface of window 1 during operation to ensure cleaning effectiveness. In non-operational states (such as during reset or maintenance), they are kept away from the glass to avoid unnecessary wear, resistance, and safety risks. The elastic pressing mechanism 31 has a certain buffering capacity, ensuring that the modular cleaning components maintain uniform pressure when encountering minor unevenness in the glass, preventing scratches and ensuring effective cleaning. Furthermore, the elastic pressing mechanism 31 has a certain degree of elasticity and adjustability to prevent excessive pressure between the modular cleaning components and the glass, which could cause damage. The drive system includes a first drive mechanism 41 and a second drive mechanism 42. The first drive mechanism 41 drives and connects to the second drive mechanism 42, responsible for driving the second drive mechanism 42, along with the cleaning head assembly 3, to perform precise lifting and lowering movements along the guide rail 2. The second drive mechanism 42 is mounted on the moving part of the first drive mechanism 41, and its output end is connected to the cleaning head assembly 3. The second drive mechanism 42 is responsible for driving the cleaning head assembly 3 to move laterally and reciprocally in a horizontal direction parallel to the plane of the window 1 to achieve all-round cleaning of the glass. The fluid supply unit includes a cleaning water tank 51 and a spray unit 52 installed at the top of the window 1. The cleaning water tank 51 can store clean water or cleaning solution and is connected to the spray unit 52 through a pipe 53. The control unit is located indoors and is an integrated controller with a user interface (such as a touch screen or button panel). The control unit is electrically connected to the cleaning head assembly 3, the drive system and the fluid supply unit, and is responsible for receiving instructions, sending control signals and monitoring the system status. The water collection unit is fixedly installed on the outer edge of the bottom of the window 1. Its function is to collect the cleaning wastewater flowing down from the glass surface to avoid sewage pollution of the building exterior wall or making the ground slippery. Through the setting of the above components, the automatic water spraying, wiping and water collection process of the high-altitude window is realized. The cleaning efficiency is high and the manual intervention is greatly reduced. By fixing the spray unit 52 at the top of the window and separating it from the cleaning head assembly 3, the problems of entanglement, wear and maintenance caused by the movement of water pipes with the cleaning head assembly 3 are completely avoided, the system structure is simplified and the long-term reliability is improved.

[0026] Optionally, in this embodiment, the modular cleaning component includes a wiper module 32 (which may be made of elastic materials such as rubber or silicone) and a quick-release mechanism 33. The quick-release mechanism 33 includes a fixing base 331, a locking spring 332, and an unlocking button 333. The fixing base 331 has a guide groove 3311 for inserting the wiper module, the shape of which matches the cross-section of the wiper module to guide the wiper module to be inserted accurately. The locking spring 332 is preferably made of spring steel sheet by stamping and bending, and has excellent elasticity and wear resistance. One end of the locking spring 332 is a fixed end 3321, and the other end is a free end 3322, which is suspended above the guide groove 3311. The free end 3322 has an inwardly bent locking part 3323 in the middle, preferably a hook. The wiper module has a locking boss 322 that cooperates with the locking part 3323, preferably a step or recess that matches the shape of the hook. Further, the unlocking button 333 is slidably disposed on the side of the fixed base 331. The inner side of the unlocking button 333 has a transmission slope 335. The free end 3322 of the locking spring 332 has a driven part 3324 that cooperates with the transmission slope 335. The fixed base 331 has a return spring 334 to provide a force for the unlocking button 333 to return backward. The wiper module has a guide slope 321 to guide and deform the locking spring 332.

[0027] When installing the wiper module, align the wiper module with the guide groove 3311 of the mounting base 331 and push it forward. The guide ramp 321 at the front end of the wiper module first contacts the locking part 3323 of the free end 3322 of the locking spring 332. As it continues to push forward, the guide ramp 321 squeezes the hook, using the ramp to convert the horizontal thrust into a vertical component, forcing the free end 3322 of the locking spring 332 to elastically bend and deform, thus making way for the wiper module. When the wiper module is fully pushed in, its locking boss 322 just passes the hook. At this moment, the locking spring 332 releases its accumulated elastic potential energy instantly due to the loss of pressure, and the free end 3322 drives the hook to quickly spring back. The springing hook clicks and engages with the rear of the locking boss 322, tightly meshing with the vertical locking surface, thus firmly locking the wiper module in the mounting base 331, completing the installation. When the wiper module needs to be replaced, the user presses the unlock button 333. The button slides forward against the force of the return spring 334, and the inner transmission ramp 335 moves forward accordingly. The transmission ramp 335 contacts the driven part 3324 on the locking spring 332 and slides relative to it. Due to the action of the ramp, as the transmission ramp 335 moves forward, it will generate a thrust on the driven part 3324 in a direction away from the wiper module, forcing the free end 3322 to bend and deform again. As the amount of deformation increases, the locking part 3323 is gradually lifted and eventually completely disengages from the locking surface of the locking boss 322, and the locking state is released, allowing the wiper module to be replaced. After releasing the unlock button 333, the button automatically slides back to the initial position under the action of the return spring 334; at the same time, the locking spring 332 also returns to its original position.

[0028] Optionally, in this embodiment, the second drive mechanism 42 is fixedly mounted on a lifting slider 411, which is directly driven by the first drive mechanism 41 and can move up and down along the guide rail 2. The cleaning head assembly 3 is mounted on the slide of the second drive mechanism 42 through a connector, so as to realize the vertical and horizontal movement of the cleaning head assembly 3.

[0029] Optionally, in this embodiment, the elastic clamping mechanism 31 can be selected from one of a hydraulic push rod, a pneumatic push rod, or a linear motor; the control unit can precisely control the extension amount of the elastic clamping mechanism 31; in cleaning mode, the control unit instructs the elastic clamping mechanism 31 to press the wiper module 32 against the glass with a preset pressure. This pressure can be adaptively adjusted according to the flatness of the glass or the cleaning program, ensuring the wiping effect while preventing excessive pressure from damaging the glass; when the cleaning head needs to move laterally to change lanes or return to the top, the control unit instructs the elastic clamping mechanism 31 to retract slightly, so that the wiper module 32 maintains a small gap (e.g., 1-2 mm) with the glass, reducing movement resistance. When entering maintenance mode, the elastic clamping mechanism 31 is fully retracted, so that the entire cleaning head assembly 3 is away from the glass surface, leaving a safe space for manual inspection or maintenance. It adapts to different working conditions and protects the glass surface.

[0030] Optionally, in this embodiment, the spray pipe of the spray unit 52 has multiple nozzles evenly distributed, which can spray the cleaning liquid evenly and completely onto the glass area to be cleaned, forming a water film, softening and removing stains, and creating good conditions for subsequent scraping.

[0031] Optionally, in this embodiment, the control module built into the control unit presets multiple modes: Single cleaning mode: The user starts with one button, and the system automatically performs a complete top-to-bottom cleaning cycle of "spraying-scraping-water collection", suitable for daily cleaning. The control module controls the spray unit 52 to start and spray continuously for a preset time. Then, it controls the elastic clamping mechanism 31 to press the modular cleaning component against the window surface. The first drive mechanism 41 and the second drive mechanism 42 drive the cleaning head component to perform a complete wiping cycle. After wiping, the control module controls the elastic clamping mechanism 31 to move the modular cleaning component away from the window surface. Cyclic cleaning mode: Suitable for extremely dirty glass or after rain, the system can continuously perform two or more single cleaning cycles until the preset cleaning standard is reached. Inspection mode: Used for maintenance. After starting, the cleaning head component 3 automatically moves to the preset inspection position on the side or bottom of the window 1, the elastic clamping mechanism 31 retracts, and all drives are powered off and locked to ensure personnel safety. It provides flexible work options to adapt to different scenario needs.

[0032] Optionally, in this embodiment, the cleaning system also includes an emptying mode. In winter or before long-term disuse, the user can activate this mode. The control module will command the water pump to run in reverse or open the pressure relief valve, and at the same time control the drive system to move the cleaning head assembly 3 to a specific position to completely empty the residual liquid in the spray pipe 53, spray unit 52 and components that may contain water, effectively preventing the pipe 53 or components from cracking due to liquid freezing.

[0033] Optionally, in this embodiment, the water collection unit includes a water collection tank 61, a pressure sensor located at the bottom of the inner wall of the water collection tank 61, and a valve 62 connected to the pressure sensor. A pressure sensor (or liquid level sensor) is installed on the inner side of the bottom of the water collection tank 61. When clean wastewater flows in and the liquid level reaches a certain height to generate a specific pressure, the pressure sensor signal is triggered, and the control unit automatically opens the valve 62 connected to the drain pipe 63 to drain the water. After draining to a low water level, the valve 62 closes, realizing the automated management of wastewater collection and discharge, and avoiding the overflow problem caused by forgetting to drain the water. In other embodiments, an overflow weir can also be used. By setting the height of the overflow weir, the discharge water level of the wastewater can be controlled and adjusted to realize the automatic discharge of wastewater; or a mechanical float valve structure can be used instead of the pressure sensor and valve. The rise of the water level drives the float to rise. The float is connected to the valve or sealing plug to realize automatic drainage. No limitation is made here.

[0034] The embodiments described above merely illustrate implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
