Description

Technical Field

[0001] The invention belongs to the technical field of curtain walls, and in particular relates to a glass curtain wall capable of automatically cleaning the outer side of the glass. Background Art

[0002] Glass curtain wall is a kind of external protective structure or decorative structure widely used in modern buildings. It mainly installs a glass panel on a metal mounting base, and then fixes the metal mounting base on the wall of the building to enhance the beauty of the building. If energy-saving materials such as hollow glass are used, it can also effectively insulate sound and heat, reduce indoor lighting and air-conditioning energy consumption, and achieve warmth in winter and coolness in summer.

[0003] After a glass curtain wall has been used for a period of time, the glass surface on the outside of the glass curtain wall needs to be cleaned to ensure the light transmittance and aesthetics of the glass. Traditional cleaning requires manual cleaning operations by hanging on the wall. In order to achieve the function of automatic cleaning, existing glass curtain walls will be equipped with a cleaning mechanism on the outside of the glass curtain wall. However, the cleaning mechanism will protrude from the outer surface of the curtain wall, affecting the appearance. In addition, the protruding cleaning mechanism is prone to accumulation of dust, dirt and other pollutants (which can easily cause transmission components to operate poorly), requiring frequent cleaning and maintenance, which is more troublesome. Summary of the Invention

[0004] In response to the above problems, the purpose of the present invention is to provide a glass curtain wall that automatically cleans the outside of the glass. The transmission structure such as the screw rod, motor and movable plate can be stored in the circular groove along with the circular mounting plate. At the same time, the circular sealing plate can cover the circular groove to prevent the transmission structure from being exposed to the external environment for a long time and accumulating dust, thereby reducing the maintenance frequency of the cleaning mechanism. At the same time, after storage, the outer surface of the glass curtain wall is kept flat, thereby increasing the aesthetics of the glass curtain wall. When cleaning is needed, the screw rod lifting mechanism is controlled to push out the circular mounting plate so that the rubber scraper is flush with the outer surface of the glass plate, and then the motor is controlled to rotate to drive the movable plate to move downward, so that the rubber scraper scrapes off the dust on the surface of the glass plate, thereby achieving automatic cleaning.

[0005] The technical solution adopted in the present invention is as follows: A glass curtain wall for automatically cleaning the outer side of the glass comprises a mounting seat, a glass plate is mounted on the mounting seat, a return groove is formed on the mounting seat and is located on the outer side of the glass plate, a return mounting plate is movably arranged in the return groove, a screw lifting mechanism connected to the return mounting plate is arranged in the return groove, a screw is vertically rotatably arranged on one side of the return mounting plate, the screw is connected to a motor, a guide rod is vertically arranged on the other side of the return mounting plate, a movable plate slidably connected to the guide rod is threadedly connected to the screw rod, a rubber scraper for scraping the glass plate is arranged on the movable plate, and a return sealing plate for covering the return groove is fixedly arranged on the return mounting plate.

DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0017] The following combination Figures 1-9 The present invention is described in detail.

[0018] The present invention provides a glass curtain wall that automatically cleans the outer side of the glass, including a mounting base 1, a glass plate 2 is mounted on the mounting base 1, a return groove 4 is opened on the mounting base 1 and is located on the outer side of the glass plate 2, a return mounting plate 5 is movably arranged in the return groove 4, a screw lifting mechanism 17 connected to the return mounting plate 5 is arranged in the return groove 4, a screw 3 is vertically rotatably arranged on one side of the return 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 return mounting plate 5, a movable plate 15 is threadedly connected to the screw 3 and is slidably connected to the guide rod 14, a rubber scraper 19 is arranged on the movable plate 15 for scraping the glass plate 2, and a return sealing plate 18 for covering the return groove 4 is fixedly arranged on the return mounting plate 5.

[0019] The transmission structure including the screw rod 3, the motor 6 and the movable plate 15 can be stored in the circular groove 4 along with the circular mounting plate 5. At the same time, the circular sealing plate 18 can cover the circular groove 4 to prevent the transmission structure from being exposed to the external environment for a long time and accumulating dust, thereby reducing the maintenance frequency of the cleaning mechanism. At the same time, after storage, the outer surface of the glass curtain wall is kept flat, which increases the aesthetics of the glass curtain wall. When cleaning is needed, the screw rod lifting mechanism 17 is controlled to push out the circular mounting plate 5 so that the rubber scraper 19 is flush with the outer surface of the glass plate 2, and then the motor 6 is controlled to rotate and drive the movable plate 15 to move downward, so that the rubber scraper 19 scrapes off the dust on the surface of the glass plate 2 to achieve automatic cleaning.

[0020] The circular sealing plate 18 is provided with a sealing gasket that seals the gap between the circular sealing plate 18 and the mounting base 1, reducing dust from entering the circular groove 4. The back of the mounting base 1 is provided with a hole for access to the screw jacking mechanism 17. The mounting base 1 is made of aluminum alloy, maintaining structural strength while reducing the weight of the entire glass curtain wall. This application provides for programmable control of the relevant electrical appliances to achieve automated operation. Alternatively, a corresponding in-position switch can be provided to assist in moving the movable plate 15 and the circular mounting plate 5 to the correct position and achieve automated operation.

[0021] The back of the mounting base 1 is provided with a mounting bracket 7. Expansion bolts are installed on the mounting bracket 7 and the mounting base 1 is fixed to the wall through the expansion bolts.

[0022] A water tank 11, located above the glass sheet 2, is mounted on the circular mounting plate 5. An exhaust valve 9 is provided on the water tank 11. A pressure pump 8, connected to the water tank 11, is also mounted on the circular mounting plate 5. This pressure 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. The distribution pipe 12 is connected to a movable plate 15 via these connecting pipe assemblies 13. The movable plate 15 is also equipped with an atomizing nozzle 20, which is connected to the connecting pipe assemblies 13. The suction pipe of the pressure pump 8 is connected to the bottom of the water tank 11, and the output pipe of the pressure pump 8 is connected to the distribution pipe 12. The atomizing nozzle 20 is located below the rubber scraper 19 and faces the glass sheet 2.

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

[0024] The exhaust valve 9 includes an exhaust pipe 901, in which an annular plate 902 is fixedly disposed, and a buoyancy plate 903 is hingedly connected to the lower surface of the annular plate 902. The exhaust valve 9 can maintain the internal and external air pressure balance of the water tank 11, thereby facilitating the replenishment or suction of cleaning liquid. Specifically, the end of the buoyancy plate 903 naturally abuts the lower surface of the annular plate 902, so that the buoyancy plate 903 remains in an inclined state, thereby maintaining the exhaust valve 9 in an open state, thereby connecting the internal and external environments of the water tank 11. When the cleaning liquid 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 exhaust valve 9, preventing excessive cleaning liquid from leaking out of the water tank 11.

[0025] The connecting pipe assembly 13 includes a joint pipe 131 fixed on the distribution pipe 12 and a plug 135 fixed on the movable plate 15. The joint pipe 131 is provided with a tapered mouth 132 and an annular seat 134 located below the tapered mouth 132. The annular seat 134 and the plug 135 are in sliding and sealing cooperation. The inner wall of the annular seat 134 is provided with a sealing ring to seal the gap between the plug 135 and the annular seat 134 to prevent liquid leakage. When the cleaning liquid is atomized and sprayed, it is necessary to control the movable plate 15 to move downward a certain distance, but it is also necessary to maintain the sliding and sealing cooperation between the plug 135 and the annular seat 134. At this time, the atomizing nozzle 20 moves to align with the upper edge of the glass plate 2 to spray the cleaning liquid. After the spraying is completed, the movable plate 15 is controlled to continue to move downward, so that the rubber scraper 19 performs a cleaning and scraping operation on the glass plate 2 from top to bottom. Among them, since a screw lifting mechanism 17 is provided, after the rubber scraper 19 moves to the bottom of the glass plate 2, the screw lifting mechanism 17 can be controlled to further lift so that the rubber scraper 19 does not contact the glass plate 2, and then the movable plate 15 is controlled to move upward to prevent dust attached to the lower surface of the rubber scraper 19 from contaminating the glass plate 2.

[0026] After the pressurized delivery pump 8 is turned off and the cleaning liquid stops spraying, some cleaning liquid will remain in the distribution pipe 12 and not be sprayed out. If the movable plate 15 does not move downward, the cleaning liquid will flow to the atomizing nozzle 20 and outflow, causing waste (cleaning liquid without pressure delivery cannot be sprayed onto the glass plate 2). If the movable plate 15 moves downward, the cleaning liquid will flow directly out of the joint pipe 131, which will also cause waste. Therefore, a blocking ball 133 is movably installed between the tapered opening 132 and the annular seat 134, and a through hole 136 is opened on the upper side wall of the insertion pipe 135. Figure 7As shown, when in state one, the blocking ball 133 is abutted against the conical opening 132 by the cannula 135, thereby blocking the outflow of the cleaning liquid; when in state two, the pressurized delivery pump 8 is turned on to pressurize the cleaning liquid, and the cleaning liquid flows into the cannula 135 through the through hole 136 and is finally sprayed out from the atomizing nozzle 20 in the form of atomizer; when in state three, the movable plate 15 drives the rubber scraper 19 to perform the cleaning operation, and the cannula 135 moves downward with the movable plate 15. At this time, the blocking ball 133 cooperates with the annular seat 134 to prevent leakage of the cleaning liquid. Even if the movable plate 15 is reset upward to reinsert the cannula 135 into the joint pipe 131, less cleaning liquid will be wasted from the joint pipe 131. Therefore, the provision of the blocking ball 133 can greatly reduce the waste of cleaning liquid and reduce the frequency of replenishing the cleaning liquid.

[0027] Among them, the blocking ball 133 includes a solid metal, and the solid metal ball is wrapped with an elastic rubber layer to ensure that the blocking ball 133 can sink in the water. At the same time, when squeezed by the cannula 135, it can undergo a certain elastic deformation to prevent the cannula 135 from abutting against the blocking ball 133 upward to cause hard contact and damage the blocking ball 133 or the cannula 135.

[0028] A rigid water supply pipe 10 is connected to the top of the water tank 11. This pipe 10 extends vertically through the return groove 4 and is connected to a flexible hose 16. Made of stainless steel, it moves with the water tank 11. The flexible hose 16 maintains its connection to the pipe through its own deformation. When the cleaning fluid needs to be replenished, it 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 make the excess cleaning liquid on both sides converge to the middle, so that the cleaning liquid can evenly cover the surface of the glass plate 2, thereby improving the cleaning effect.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.
