Description

Technical Field

[0001] This invention belongs to the field of curtain wall technology, and specifically relates to a glass curtain wall that automatically cleans the exterior of the glass. Background Technology

[0002] Glass curtain walls are a widely used exterior envelope or decorative structure in modern buildings. They mainly consist of a glass panel mounted on a metal mounting base, which is then fixed to the building's wall. This enhances the building's aesthetics. If energy-saving materials such as double-glazed windows are used, they can also effectively insulate against sound and heat, reduce indoor lighting and air conditioning energy consumption, and achieve a comfortable temperature year-round.

[0003] After a period of use, glass curtain walls require cleaning of the outer glass surface to ensure light transmission and aesthetics. Traditional cleaning requires manual cleaning from the wall. To achieve automatic cleaning, existing glass curtain walls have cleaning mechanisms installed on the outer side. However, these mechanisms protrude from the outer surface, affecting aesthetics. Furthermore, protruding cleaning mechanisms easily accumulate dust, dirt, and other contaminants (potentially causing malfunctions in transmission components), requiring frequent cleaning and maintenance, which is quite troublesome. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide an automatic cleaning system for the exterior of glass curtain walls. The transmission structure, including the lead screw, motor, and moving plate, can be housed within a U-shaped groove along with the U-shaped mounting plate. Simultaneously, a U-shaped sealing plate covers the U-shaped groove, preventing the transmission structure from being exposed to the external environment for extended periods and accumulating dust, thus reducing the maintenance frequency of the cleaning mechanism. Furthermore, the housed system maintains a flat outer surface of the glass curtain wall, enhancing its aesthetics. When cleaning is required, the lead screw lifting mechanism pushes the U-shaped mounting plate out, aligning the rubber scraper with the outer surface of the glass panel. Then, the motor rotates, driving the moving plate downwards, allowing the rubber scraper to remove dust from the glass panel surface, achieving automatic cleaning.

[0005] The technical solution adopted in this invention is as follows: An automatic cleaning glass curtain wall includes a mounting base on which a glass panel is mounted. The mounting base has a U-shaped groove on the outside of the glass panel. A U-shaped mounting plate is movably disposed within the U-shaped groove. A screw-driven lifting mechanism connected to the U-shaped mounting plate is disposed within the U-shaped groove. A screw is vertically rotatably mounted on one side of the U-shaped mounting plate and connected to a motor. A guide rod is vertically mounted on the other side of the U-shaped mounting plate. A movable plate, threadedly connected to the screw and slidably connected to the guide rod, is mounted on the movable plate. A rubber scraper for cleaning the glass panel is disposed on the movable plate. A U-shaped sealing plate for covering the U-shaped groove is fixedly mounted on the U-shaped mounting plate.

[0006] Preferably, the mounting base is provided with a mounting bracket on its back.

[0007] Preferably, a water tank is installed on the U-shaped mounting plate above the glass plate. The water tank is equipped with an exhaust valve. A pressurized delivery pump connected to the water tank is installed on the U-shaped mounting plate. The pressurized delivery pump is connected to a distribution pipe fixed on the water tank. Several connecting pipe assemblies are vertically installed on the distribution pipe. The distribution pipe is connected to a movable plate through the connecting pipe assemblies. An atomizing nozzle connected to the connecting pipe assemblies is installed on the movable plate.

[0008] Preferably, the exhaust valve includes an exhaust pipe, in which an annular plate is fixedly disposed, and a buoyancy plate is hinged to the lower surface of the annular plate.

[0009] Preferably, the connecting pipe assembly includes a connector pipe fixed on the distribution pipe and an insert pipe fixed on the movable plate. The connector pipe is provided with a tapered opening and an annular seat located below the tapered opening. The annular seat and the insert pipe are in a sliding sealing fit.

[0010] Preferably, a sealing ball is movably disposed between the conical opening and the annular seat, and a through hole is provided on the upper side wall of the insertion tube.

[0011] Preferably, the top of the water tank is connected to a rigid water supply pipe, which moves along the direction perpendicular to the glass plate, passes through the U-shaped groove, and is connected to a flexible hose.

[0012] Preferably, the rubber scraper is arranged in a V-shape.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: The transmission structure, including the lead screw, motor, and moving plate, can be stored in the U-shaped groove along with the U-shaped mounting plate. Simultaneously, the U-shaped sealing plate covers the groove, preventing the transmission structure from accumulating dust due to prolonged exposure to the external environment, thus reducing the maintenance frequency of the cleaning mechanism. Furthermore, the stored structure keeps the outer surface of the glass curtain wall flat, enhancing its aesthetics. When cleaning is required, the lead screw lifting mechanism pushes the U-shaped mounting plate out, aligning the rubber scraper with the outer surface of the glass panel. Then, the motor rotates, driving the moving plate downwards, allowing the rubber scraper to remove dust from the glass panel surface, achieving automatic cleaning. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] The following is combined Figures 1-9 The present invention will be described in detail below.

[0018] The present invention provides an automatic cleaning glass curtain wall for the outside of the glass, including a mounting base 1, on which a glass plate 2 is mounted. A U-shaped groove 4 is formed on the mounting base 1 on the outside of the glass plate 2. A U-shaped mounting plate 5 is movably arranged in the U-shaped groove 4. A screw lifting mechanism 17 connected to the U-shaped mounting plate 5 is arranged in the U-shaped groove 4. A screw 3 is vertically rotatably arranged on one side of the U-shaped mounting plate 5. The screw 3 is connected to a motor 6. A guide rod 14 is vertically arranged on the other side of the U-shaped mounting plate 5. A movable plate 15 is threadedly connected to the screw 3 and slidably connected to the guide rod 14. A rubber scraper 19 for cleaning the glass plate 2 is arranged on the movable plate 15. A U-shaped sealing plate 18 for covering the U-shaped groove 4 is fixedly arranged on the U-shaped mounting plate 5.

[0019] The transmission structure, including the lead screw 3, motor 6, and moving plate 15, can be stored in the U-shaped groove 4 along with the U-shaped mounting plate 5. At the same time, the U-shaped sealing plate 18 can cover the U-shaped groove 4 to prevent the transmission structure from accumulating dust due to long-term exposure to the external environment, thus reducing the maintenance frequency of the cleaning mechanism. After storage, the outer surface of the glass curtain wall remains flat, increasing its aesthetics. When cleaning is required, the lead screw lifting mechanism 17 is controlled to push the U-shaped mounting plate 5 out, making the rubber scraper 19 flush with the outer surface of the glass panel 2. Then, the motor 6 is controlled to rotate and drive the moving plate 15 to move downward, allowing the rubber scraper 19 to scrape away the dust on the surface of the glass panel 2, thus achieving automatic cleaning.

[0020] The U-shaped sealing plate 18 is equipped with a sealing gasket, which seals the gap between the U-shaped sealing plate 18 and the mounting base 1, reducing dust entering the U-shaped groove 4. The back of the mounting base 1 has a hole to allow the lead screw lifting mechanism 17 to pass. The mounting base 1 is made of aluminum alloy, reducing the weight of the entire glass curtain wall while maintaining structural strength. This application includes a related electrical setting program to automate operation; alternatively, a positioning switch can be set to assist the moving plate 15 and the U-shaped mounting plate 5 in moving to the accurate position and automating the operation.

[0021] Mounting base 1 has a mounting bracket 7 on its back. Expansion bolts are installed on the mounting bracket 7, and the mounting base 1 is fixed to the wall by the expansion bolts.

[0022] A water tank 11 is mounted on the U-shaped mounting plate 5, located above the glass plate 2. An exhaust valve 9 is installed on the water tank 11. A pressurized delivery pump 8, connected to the water tank 11, is mounted on the U-shaped mounting plate 5. The pressurized delivery pump 8 is connected to a distribution pipe 12 fixed to the water tank 11. Several connecting pipe assemblies 13 are vertically mounted on the distribution pipe 12, which is connected to a movable plate 15 via the connecting pipe assemblies 13. An atomizing nozzle 20, connected to the connecting pipe assemblies 13, is mounted on the movable plate 15. The suction pipe of the pressurized delivery pump 8 is connected to the bottom of the water tank 11, and the output pipe of the pressurized delivery pump 8 is connected to the distribution pipe 12. The atomizing nozzle 20 is located below the rubber scraper 19 and faces the glass plate 2.

[0023] The water tank 11 stores cleaning fluid (or clean water). The pressurized delivery pump 8 pressurizes and pumps the cleaning fluid. The cleaning fluid passes through the distribution pipe 12 and the connecting pipe assembly 13 and is finally atomized and sprayed out from the atomizing nozzle 20. The cleaning fluid is sprayed onto the glass plate 2, and more cleaning fluid can be sprayed out, so that the cleaning fluid flows downwards from the glass plate 2. The pressurized delivery pump 8 is turned off and the motor 6 is started, so that the moving plate 15 and the rubber scraper 19 move downwards to scrape off the softened dust and the cleaning fluid mixed with the dust, so as to ensure the cleanliness of the glass plate 2.

[0024] The vent valve 9 includes a vent pipe 901, in which an annular plate 902 is fixedly installed. A buoyancy plate 903 is hinged to the lower surface of the annular plate 902. The vent valve 9 can maintain the internal and external air pressure balance of the water tank 11, thereby facilitating the replenishment or suction of cleaning fluid. Specifically, the end of the buoyancy plate 903 abuts against the lower surface of the annular plate 902 in its natural state, thus keeping the buoyancy plate 903 in an inclined state, thereby keeping the vent valve 9 open and connecting the internal and external environments of the water tank 11. When the cleaning fluid is replenished, the liquid level rises and contacts the buoyancy plate 903, which can drive the buoyancy plate 903 to flip upward, thereby closing the vent valve 9 and preventing excessive replenishment of cleaning fluid from leaking out of the water tank 11.

[0025] The connecting pipe assembly 13 includes a connector pipe 131 fixed to the distribution pipe 12 and an insert pipe 135 fixed to the moving plate 15. The connector pipe 131 has a tapered opening 132 and an annular seat 134 located below the tapered opening 132. The annular seat 134 and the insert pipe 135 are in a sliding sealing fit. A sealing ring is provided on the inner wall of the annular seat 134 to seal the gap between the insert pipe 135 and the annular seat 134 to prevent liquid leakage. When the cleaning fluid is atomized and sprayed, the moving plate 15 needs to be controlled to move downward a certain distance, but the sliding sealing fit between the insert pipe 135 and the annular seat 134 also needs to be maintained. At this time, the atomizing nozzle 20 moves to the position aligned with the upper edge of the glass plate 2 to spray the cleaning fluid. After spraying, the moving plate 15 is controlled to continue to move downward, so that the rubber scraper 19 cleans and scrapes the glass plate 2 from top to bottom. The screw lifting mechanism 17 is provided so that after the rubber scraper 19 moves to the bottom of the glass plate 2, the screw lifting mechanism 17 can be controlled to lift further so that the rubber scraper 19 does not contact the glass plate 2. Then the moving plate 15 is controlled to move upward to avoid dust adhering to the lower surface of the rubber scraper 19 from contaminating the glass plate 2.

[0026] After the pressurized delivery pump 8 is shut off and the cleaning fluid spraying stops, some cleaning fluid will remain in the distribution pipe 12. If the moving plate 15 does not move downwards, the cleaning fluid will flow to the atomizing nozzle 20 and be wasted (cleaning fluid without pressure cannot be sprayed onto the glass plate 2). If the moving plate 15 moves downwards, the cleaning fluid will flow directly out from the connector pipe 131, also resulting in waste. Therefore, a sealing ball 133 is movably arranged between the conical opening 132 and the annular seat 134, and a through hole 136 is opened on the upper side wall of the insertion tube 135. Figure 7As shown, in state one, the sealing ball 133 is pressed against the conical opening 132 by the insertion tube 135, thereby blocking the outflow of cleaning fluid. In state two, the pressurized delivery pump 8 is turned on to pressurize and deliver the cleaning fluid, which flows into the insertion tube 135 through the through hole 136 and is finally atomized and sprayed out from the atomizing nozzle 20. In state three, the moving plate 15 drives the rubber scraper 19 to perform the cleaning operation, and the insertion tube 135 moves downward with the moving plate 15. At this time, the sealing ball 133 cooperates with the annular seat 134 to prevent leakage of cleaning fluid. Even when the moving plate 15 is reset upward to allow the insertion tube 135 to be reinserted into the connector tube 131, the amount of cleaning fluid wasted from the connector tube 131 is minimal. Therefore, the sealing ball 133 can greatly reduce the waste of cleaning fluid and reduce the frequency of replenishing the cleaning fluid.

[0027] The occlusion ball 133 includes a solid metal ball, which is wrapped with an elastic rubber layer to ensure that the occlusion ball 133 can sink in water. At the same time, when it is squeezed by the insertion tube 135, it can undergo a certain elastic deformation to prevent the insertion tube 135 from hitting the occlusion ball 133 upward and causing hard contact that could damage the occlusion ball 133 or the insertion tube 135.

[0028] A rigid water supply pipe 10 is connected to the top of the water tank 11. The rigid water supply pipe 10 moves along the direction perpendicular to the glass plate 2, passes through the U-shaped groove 4, and is connected to a flexible hose 16. The rigid water supply pipe 10 can be made of stainless steel and can move with the water tank 11. The flexible hose 16 can maintain its connection with the rigid water supply pipe 10 through its own deformation. When the cleaning fluid needs to be replenished, the cleaning fluid is delivered to the water tank 11 through the flexible hose 16.

[0029] The rubber scraper 19 is arranged in a V-shape, which can cause excess cleaning liquid on both sides to converge in the middle, so that the cleaning liquid can be evenly covered on the surface of the glass plate 2, improving the cleaning effect.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
