[0054] The following will describe in more detail the switchable working mode building curtain wall cleaning device and method of this utility model with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0055] A switchable working mode building curtain wall cleaning device integrates spraying, brushing, sewage collection and recycling functions through modular design. It is especially suitable for cleaning glass, metal and stone curtain walls and features high efficiency, safety, energy saving and environmental protection.

[0056] Based on existing technology, the curtain wall panel 1 and the curtain wall decorative strip 2 are a single unit.

[0057] like Figures 1-10 , Figures 11-16 A switchable working mode building curtain wall cleaning device, comprising:

[0058] The cleaning frame, which can move along the curtain wall decorative strip 2 and in the Z direction, has an inward recess on the side facing the curtain wall panel 1 to form a mounting cavity, such as... Figures 1-6 .

[0059] A roller-type soft brush 11 is used to clean the curtain wall panel 1. It is located in the mounting cavity. The ends of its brush shaft along the X direction are connected to the output end of a brush drive motor 13 via belt drive. The brush drive motor 13 is fixed to the corresponding electric brush swing arm 12.

[0060] The brush shaft is integrally fixedly connected to or pressurized with the body of the roller-type soft brush 11 to form the roller-type soft brush 11.

[0061] The electric brush arm 12 drives the roller-type soft brush 11 to swing around the X-axis. Its lower end is rotatably connected to the brush shaft, and its upper end is connected to the housing of the brush arm drive motor 21. In this embodiment, the hole on the brush arm 12 is clearance-fitted with the brush shaft. In other embodiments, the brush shaft is rotatably connected to the brush arm 12 via a bearing.

[0062] Regarding the above connections, it can be seen from... Figures 2-4 , Figure 8 Displayed.

[0063] The swing arm drive motor 21 has its output shaft extending along the X direction and is rotatably mounted on the cleaning frame.

[0064] Figures 2-4 In the middle, the structure between the brush drive motor 13 and the cleaning frame is a transition pipe connecting the brush cleaning nozzle 16 and the clean water pipe 7.

[0065] The brush cleaning nozzle 16 is fixed to the housing of the swing arm drive motor, which is a YVP-63 variable frequency speed control micro motor.

[0066] like Figures 17-18 This is a connection diagram of the electric brush arm 12, the arm drive motor 21, and the brush drive motor 13 in other embodiments.

[0067] Figures 17-18 In contrast to this embodiment Figures 2-4 , Figures 7-8 The only difference is the relative position of the swing arm drive motor 21 and the brush drive motor 13; the rest of the structure and connection are the same.

[0068] Since the brush cleaning nozzle 16 can swing with the brush arm 12, the transition tube connecting the brush cleaning nozzle 16 is in a bent state so that it can enter and exit the cleaning frame with the swinging motion.

[0069] The Y-axis moving unit is used to change the Y-axis distance between the cleaning frame and the curtain wall panel 1. It is fixed to the cleaning frame and its output end is connected to the wheel frame. In this embodiment, the Y-axis moving unit is a hydraulic support 10.

[0072] The clean water pipe 7 is connected to the water tank 3 at its upper end and to the spray unit on the cleaning frame at its lower end. The spray unit is set facing the curtain wall panel 1.

[0073] The cleaning frame includes a sewage tank 20 and a sewage pipe 8. The bottom surface of the cleaning frame is open and connected to the upper surface of the sewage tank 20. The sewage tank 20 is inclined to the side facing the curtain wall panel 1 and a bottom waterproofing strip 19 is installed. The sewage pipe 8 is connected to the water tank 3 at its upper end and to the sewage tank 20 at its lower end.

[0074] like Figure 13 As shown, the upper surface of the sewage tank 20 is open, and the bottom surface of the cleaning frame is open.

[0075] Sewage pipe 8 connects to the second chamber of water tank 3, and a water pump is installed in the second chamber; clean water pipe 7 connects to the first chamber of water tank 3.

[0076] Chamber 1 and Chamber 2 are not connected.

[0077] In this embodiment, the belt drive includes:

[0078] The driving wheel and the driven wheel are connected by a brush drive belt 14;

[0079] The drive wheel is fixedly or rotatably connected to the output end of the brush drive motor 13, and the drive wheel is fixedly or rotatably mounted on the end of the brush shaft.

[0080] In this embodiment, a transmission belt 14 can be directly installed between the output end of the brush drive motor 13 and the brush shaft, that is, the transmission belt 14 connects the brush shaft and the output end of the brush drive motor 13.

[0081] like Figure 14 As shown, the electric brush arm 12 is L-shaped.

[0082] In this embodiment, a top squeegee 18 is further included, which is inclinedly disposed on the upper end face of the cleaning frame.

[0083] like Figure 8 As shown, the spray unit includes: a pre-wash nozzle 15, a brush cleaning nozzle 16, and a secondary rinsing nozzle 17, all of which are connected to the clean water pipe 7.

[0084] Figure 13 As shown, the pre-wash nozzle 15 is located below the roller-type soft brush 11, and its spray end is set towards the curtain wall panel 1.

[0085] The brush cleaning nozzle 16 and the secondary rinsing nozzle 17 are both located above the roller-type soft brush 11; the spray end of the secondary rinsing nozzle 17 is set towards the curtain wall panel 1; the spray end of the brush cleaning nozzle 16 is set towards the roller-type soft brush 11.

[0086] The pre-wash nozzle 15 is used to spray clean water or cleaning agent to moisten the surface of the curtain wall panel 1, the brush cleaning nozzle 16 is used to lubricate the roller-type soft brush 11, and the secondary rinsing nozzle 17 is used to rinse away residual dirt.

[0087] like Figures 2-4 Regarding the connection relationships between the clean water pipe 7, the secondary flushing nozzle 17, the brush cleaning nozzle 16, and the pre-wash nozzle 15:

[0088] The clean water pipe 7 includes pipes 1, 2, 3, and 4, which are sequentially connected to the water tank 3; the lower end of pipe 4 is closed. Solenoid valves are installed on pipes 1, 2, and 3 to control the flow of liquid (cleaning agent or water) within the pipes. These solenoid valves are ZCW solenoid valves (direct-acting piston type).

[0089] The secondary flushing nozzle 17 connects pipe 1 and pipe 2 via a T-junction, and the water spray pipe of the secondary flushing nozzle 17 extends out of the cleaning frame.

[0090] The brush cleaning nozzle 16 is connected to the transition pipe, which is connected to pipe No. 2 and pipe No. 3 via a T-junction.

[0091] Pre-wash nozzle 15 is connected to pipe No. 3 and pipe No. 4 via a T-junction.

[0092] Depend on Figure 13 It can be seen that the secondary rinsing nozzle 17 and the pre-rinsing nozzle 15 both pass through and extend out of the cleaning frame.

[0093] In this embodiment, a suspension cable 6 is further included, with its upper end connected to a winch 4 and its lower end connected to a cleaning frame. The suspension cable 6 is in contact with the circumferential surface of the pulley on the suspension bracket 5.

[0094] Figure 11 The relative positions of the winch and water tank 3 Figure 12 The orientation of the central suspension cable 6 differs from other diagrams. Figure 11 The remaining structures are the same as those in this embodiment. Figures 1-10 , Figures 13-16 The same as in [the previous sentence].

[0095] In summary, the device is mainly divided into seven parts: "support and tension system", "curtain wall decorative strip and limiting system", "working mode switching system", "spray system", "scrubbing system", "cleaning auxiliary system", and "sewage collection and filtration system", which are described in detail below:

[0096] 1. Support and traction system:

[0097] The cleaning device is connected to the lower end of the suspension cable 6. The suspension cable 6 is fixed by the suspension bracket 5 to avoid friction with the curtain wall system or the edge of the building. The upper end of the suspension cable 6 is fixed to the roof winch 4 to realize the vertical lifting of the equipment.

[0098] The winch 4 can adjust its height by retracting and extending the suspension cable 6, ensuring that the equipment covers the entire cleaning work area. The suspension bracket 5 is fixed to the top of the building, providing the main load-bearing capacity for the equipment.

[0099] The winch 4 is operated remotely or by an automated control module to control the lifting and lowering of the equipment, ensuring that the entire cleaning work surface is covered.

[0100] The suspension cable 6 is made of steel cable, and its specific specifications can be flexibly selected according to the actual weight of the equipment. It is used in conjunction with the limiting pulley 9 and the curtain wall decorative strip 2 to enhance the stability of the equipment.

[0101] 2. Curtain wall decorative strips and limiting system

[0102] The cleaning device is equipped with hydraulic supports 10 at the four corners. The ends of the hydraulic supports 10 are connected to limiting pulleys 9. The limiting pulleys 9 are snapped and fixed to the curtain wall decorative strips 2 to enhance the stability of the equipment and prevent deviation or derailment during the vertical lifting and working stages of the cleaning device.

[0103] The hydraulic support 10 has an adaptive buffer function to ensure that the components of the device will not be excessively squeezed against the curtain wall panel 1, thus ensuring work safety.

[0104] like Figure 16 As shown, the upper and lower ends of the curtain wall decorative strip 2 are open along the Z direction. One of the limiting pulleys 9 enters the internal guide rail of the curtain wall decorative strip 2 from the upper end and slides out of the internal guide rail of the curtain wall decorative strip 2 from the lower end.

[0105] 3. Working mode switching system

[0106] The hydraulic support 10 is directly connected to the cleaning frame and is used to control the distance between the cleaning frame and the curtain wall panel 1.

[0107] The electric brush arm 12 is connected and fixed to the roller soft brush 11. By adjusting the angle of the electric brush arm 12, the roller soft brush 11 is controlled to contact or separate from the curtain wall panel 1.

[0108] This building curtain wall cleaning device has three working modes: "lifting mode", "rinsing mode" and "brushing mode", as described below:

[0109] like Figure 2 As shown, lifting mode:

[0110] The lifting mode is used to move the equipment from one cleaning area to another, avoiding unnecessary contact with the curtain wall panel surface and improving equipment operating efficiency and protection. The curtain wall panels form several cleaning areas arranged along the Z-axis.

[0111] The electric brush arm 12 drives the roller soft brush 11 to retract completely into the equipment frame, so that the soft brush is completely separated from the curtain wall panel 1.

[0112] When the hydraulic support 10 extends, the top squeegee 18 and the bottom adhesive strip 19 maintain a certain distance from the curtain wall panel 1 to prevent friction or scratches on the curtain wall when not in operation.

[0113] At this time, the opening degree of the solenoid valve on the clean water pipe 7 is 0.

[0114] like Figure 3 Rinse mode:

[0115] The rinsing mode is used for cleaning light dirt or as a pretreatment stage before deep cleaning to reduce the resistance of stubborn dirt to the subsequent scrubbing process.

[0116] The electric brush arm 12 drives the roller-type soft brush 11 to remain in the retracted state, and the soft brush does not contact the curtain wall surface.

[0117] The hydraulic support 10 remains retracted, with the top squeegee 18 and the bottom sealant strip 19 in contact with the curtain wall surface.

[0118] Pre-wash nozzle 15 sprays clean water and detergent to wet the curtain wall surface and soften dirt.

[0119] The secondary flushing nozzle 17 starts simultaneously to assist in removing dirt residue.

[0120] The top squeegee 18 removes water stains and dirt residue, while the bottom waterproofing strip 19 helps to receive and guide sewage into the sewage collection tank 20.

[0121] like Figure 4 As shown, the scrubbing mode is:

[0122] The scrubbing mode is suitable for deep cleaning of stubborn dirt and is the main cleaning mode of the equipment, achieving a highly efficient cleaning effect on curtain wall surfaces.

[0123] The electric brush arm 12 drives the roller soft brush 11 to extend to the working position and contact the curtain wall panel 1.

[0124] The hydraulic support 10 remains retracted, ensuring that the top squeegee 18 and the bottom applicator strip 19 are in contact with the curtain wall surface, and the roller-type soft brush 11 is in contact with the curtain wall panel 1.

[0125] The pre-wash nozzle 15 sprays clean water and detergent to wet the surface of the curtain wall panel and soften the dirt. The soft brush is rotated by the brush drive motor 13 and the brush drive belt 14 to achieve physical scrubbing.

[0126] Simultaneously activate the brush cleaning nozzle 16 to spray clean water to clean the brush and provide lubrication.

[0127] The secondary flushing nozzle 17 starts simultaneously to assist in removing dirt residue.

[0128] The top squeegee 18 and the bottom adhesive strip 19 work together to remove excess water and residual cleaning agent, and the wastewater is directed into the wastewater collection tank 20 through the wastewater pipe 8.

[0129] Wastewater is guided to the wastewater tank 20 by the top squeegee 18 and the bottom squeegee 19, and is purified after multi-stage filtration.

[0130] 4. Sprinkler system (sprinkler unit)

[0131] The spray system includes a pre-wash nozzle 15, a brush cleaning nozzle 16, and a secondary rinsing nozzle 17.

[0132] The pre-wash nozzle 15 is located below the roller-type soft brush 11 and is connected to the clean water pipe 7, water pump, and water tank 3. It is used to spray clean water or cleaning agent to moisten the curtain wall surface and soften dirt.

[0133] The brush cleaning nozzle 16 is installed above the soft brush and connected to the water tank 3 via the clean water pipe 7. It is used to provide water flow for lubrication and cleaning of the brush during the cleaning process.

[0134] The secondary rinsing nozzle 17 is arranged above the equipment and connected to the water tank 3 through the clean water pipe 7, and is used to rinse away residual dirt and cleaning agents.

[0135] Furthermore, the spray angle of the nozzle is adjustable to adapt to different curtain wall surfaces.

[0136] 5. Scrubbing System

[0137] The brushing system consists of a roller-type soft brush 11, an electric brush swing arm 12, a brush drive motor 13, and a brush transmission belt 14.

[0138] The roller-type soft brush 11 is connected to the brush drive motor 13 via the transmission belt 14. The motor drives the soft brush to rotate and contact the curtain wall glass panel 1 to complete the physical cleaning. The electric brush swing arm 12 switches the contact state between the roller-type soft brush 11 and the curtain wall panel 1 through remote control or automatic control, while ensuring that the soft brush maintains appropriate contact pressure with the curtain wall surface.

[0139] 6. Cleaning Assistance System

[0140] The cleaning assistance system includes a top squeegee 18 and a bottom adhesive strip 19, which can be controlled to contact the curtain wall panel 1 as the hydraulic support 10 extends and retracts.

[0141] The top wiper strip 18 touches the curtain wall glass panel 1 to wipe away excess water from the surface.

[0142] The bottom water-applied adhesive strip 19 is attached to the surface of the curtain wall panel to guide the sewage to the sewage collection tank 20 for centralized recycling.

[0143] The cleaning assistance system works in conjunction with the spray system, operating synchronously in rinsing and scrubbing modes to ensure cleaning efficiency.

[0144] Furthermore, the top squeegee 18 and the bottom adhesive strip 19 are fixed to the cleaning frame.

[0145] 7. Wastewater collection and filtration system

[0146] Wastewater collection tank 20 is connected to wastewater pipe 8 and is used to store wastewater generated during equipment operation. Wastewater collection tank 20 is equipped with a filter module, which can perform preliminary filtration of wastewater, intercepting medium and large-sized debris such as leaves, and preventing wastewater from clogging wastewater pipe 8.

[0147] The water pump and water tank 3 are installed on the roof and have the functions of conveying clean water and recycling and filtering sewage.

[0148] The water pump and water tank 3 are connected to the spray system to provide clean water for the pre-wash nozzles 15, the brush cleaning nozzles 16, and the secondary rinsing nozzles 17. The water pump and water tank 3 are connected to the sewage collection tank 20 through the sewage pipe 8 to collect the sewage generated during the operation of the equipment. The sewage is then purified through a filtration device and subsequently recycled or discharged in a unified manner to reduce environmental pollution.

[0149] In summary, this device is an integrated, efficient, and environmentally friendly automated cleaning system that can safely and efficiently clean the curtain walls of high-rise buildings while reducing water waste and lowering operating costs. The device features spray cleaning, physical scrubbing, wastewater collection, and wastewater filtration functions, significantly improving cleaning efficiency and environmental performance while reducing cleaning costs.
