Description

Technical Field

[0001] The invention relates to the technical field of building curtain walls, in particular to a double-layer curtain wall structure of a green energy-saving building. Background Art

[0002] Nowadays, more and more high-rise buildings use double-layer curtain walls. Curtain walls are the exterior wall enclosures of buildings. Curtain walls do not bear weight but are hung like curtains, so they are also called "curtain walls". They are lightweight walls with decorative effects commonly used in modern large and high-rise buildings. Double-layer curtain walls are basically divided into two types: external circulation and internal circulation.

[0003] The outer curtain wall of the external circulation double-layer curtain wall generally adopts single-layer glass, with air inlet at the bottom and exhaust outlet at the top. The inner curtain wall adopts hollow glass and heat-insulating profiles and is equipped with openable windows or doors. It does not require special mechanical equipment and relies entirely on natural ventilation to discharge the solar radiation heat to the outside through the exhaust outlets on the passage. The outer curtain wall of the internal circulation double-layer curtain wall adopts hollow glass and heat-insulating profiles to form a closed state, and the inner curtain wall adopts single-layer glass or single-layer aluminum alloy doors and windows, which are openable. Mechanical ventilation means such as central air-conditioning systems are used to allow air to enter the passage from the air outlets on the floor or underground, and flow into the ceiling through the upper exhaust outlets.

[0004] Regardless of the type of double-layer curtain wall, the outer layer is still glass. Under the long-term exposure to the sun and rain, the surface of the outer layer of the existing double-layer curtain wall will form dust stains, dirt, and even bird droppings.

[0031] For example, see Figure 1-7 The present invention provides a double-layer curtain wall structure of a green energy-saving building, comprising an upper connecting frame 1, a guide plate 2 is fixedly connected to the bottom of the upper connecting frame 1, and a guide groove 3 is penetrated through the side wall of the guide plate 2, a screw 4 is rotatably connected to the inner wall of the guide groove 3, and a cleaning mechanism 5 is arranged on the outer wall of the screw 4, an outer curtain wall 10 is fixedly connected between the two guide plates 2, a slide groove 6 is arranged on the inner wall of the upper connecting frame 1, and a lower connecting frame 8 is fixedly connected to the bottom of the guide plate 2;

[0032] The cleaning mechanism 5 comprises a threaded block 501 and a scraper 507 , and a watering mechanism 7 is arranged inside the chute 6 .

[0033] Further, the side wall of the threaded block 501 is fixedly connected to a mounting frame 502, and the top of the mounting frame 502 is fixedly connected to a connecting plate 503, the top of the connecting plate 503 is fixedly connected to a stop block 504, the side wall of the mounting frame 502 is fixedly connected to a mounting plate 505, and the side of the mounting plate 505 close to the outer curtain wall 10 is fixedly connected to a cleaning brush 506, the top of the scraper 507 is fixedly connected to the bottom of the mounting plate 505, and the bottom of the scraper 507 is fixedly connected to the bottom of the scraper 507. The pressure block 508, the watering mechanism 7 includes a slide bar 701 and a water pipe 706, and a plurality of through holes 702 are formed through the top of the slide bar 701, an inclined groove 703 is formed at the bottom of the slide bar 701, and a tension spring 704 is fixedly connected to the side wall of the slide bar 701, and a connecting block 705 is fixedly connected to the end of the tension spring 704 away from the slide bar 701, and a diverter plate 707 is fixedly connected to the bottom of the water pipe 706, and a plurality of connecting pipes 708 are fixedly connected to the bottom of the diverter plate 707;

[0034] In this embodiment, during the use of the double-layer curtain wall, since the use environment of the outer curtain wall 10 is exposed to the sun and rain for a long time, various dust stains and dirt will form on its surface. When there is too much accumulation, it will affect the light transmittance of the double-layer curtain wall and also affect the appearance. At this time, it is necessary to drive the cleaning mechanism 5 to clean the outer curtain wall 10;

[0035] First, the motor 11 is driven, and the motor 11 outputs through the output shaft, and then the first gear 12 is driven to rotate, thereby driving the second gear 14 to rotate synchronously through the chain 13, and then the second gear 14 drives the screw 4 to rotate on the inner wall of the guide groove 3. Since the threaded block 501 and the screw 4 are threadedly connected, when the second gear 14 rotates, the threaded block 501 is driven to slide downward along the inner wall of the guide groove 3. At the same time, the threaded block 501 drives the mounting plate 505 to move through the mounting frame 502, and then the mounting plate 505 drives the cleaning brush 506 and the scraper 507 to move synchronously. During the movement of the scraper 507, the end of the scraper 507 will slide against the outer surface of the outer curtain wall 10, thereby preliminarily scraping off most of the dust adsorbed on the outer surface of the outer curtain wall 10, and then during the movement of the cleaning brush 506, the end of the cleaning brush 506 will deeply clean the outer surface of the outer curtain wall 10, so that the remaining dust that the scraper 507 cannot scrape off can be deeply cleaned;

[0036] A large water tank is installed on the roof of the building and is equipped with a water pump, which is connected to the water tank through a water pipe 706 to complete the water supply for cleaning the curtain wall. While the threaded block 501 drives the installation frame 502 to move downward, the installation frame 502 drives the block 504 to move downward synchronously through the connecting plate 503. The top of the block 504 corresponds to the inside of the inclined groove 703, the outer wall of the slide rod 701 is slidably connected to the inner wall of the slide groove 6, the inner wall of the through hole 702 corresponds to the inner wall of the connecting pipe 708, the end of the connecting block 705 away from the tension spring 704 is fixedly connected to the side wall of the guide plate 2, and then the block 504 is separated from the inclined groove. When the groove 703 is formed, the tension spring 704 will retract and reset, and then the slide bar 701 will slide along the inside of the slide groove 6. After the slide bar 701 has slid, the inside of the through hole 702 will be connected to the inside of the connecting pipe 708. Then the water in the water pipe 706 will be diverted through the diverter plate 707, and then will flow into the through hole 702 through the connecting pipe 708, and then will be sprayed from the through hole 702 to the outer surface of the outer curtain wall 10. Then, in the process of the cleaning brush 506 cleaning the outer surface of the outer curtain wall 10, the outer surface of the outer curtain wall 10 is assisted by sprinkling water, thereby effectively improving the cleaning effect.

[0037] As described above, the cleaning mechanism 5 is driven to move by the driving motor 11, so that the scraper 507 can perform preliminary scraping work on the outer surface of the outer curtain wall 10, and most of the dust can be scraped off by the scraper 507, and then the outer surface of the outer curtain wall 10 is deeply cleaned by the cleaning brush 506. After that, the scraper 507 can scrape off the water marks on the outer surface of the outer curtain wall 10 when resetting, so as to prevent water stains from being left by natural drying, thereby effectively completing the cleaning work of the outer curtain wall 10, without the need for manual high-altitude cleaning, and the cleaning process is simple and safer to operate, and the cleaning efficiency is higher;

[0038] The tension spring 704 drives the slide bar 701 to slide on the inner wall of the slide groove 6, thereby connecting the interior of the through hole 702 with the interior of the connecting pipe 708. Then, the water in the water pipe 706 enters the through hole 702 through the connecting pipe 708, and then is sprayed onto the outer surface of the outer curtain wall 10. When the cleaning brush 506 cleans the outer surface of the outer curtain wall 10, the cleaning effect of the cleaning brush 506 can be effectively improved by adding water in advance.

[0039] Embodiment 2, based on the above embodiment, a scraping mechanism 9 is provided on the side wall of the lower connecting frame 8, so that the dust adsorbed by the scraper 507 can be cleaned when cleaning the external curtain wall 10;

[0040] Furthermore, the scraping mechanism 9 includes a fixed rod 901 and a second mounting ring 905, and the outer wall of the fixed rod 901 is slidably connected to the first mounting ring 902, the side wall of the first mounting ring 902 is fixedly connected to the first inclined block 904, the side wall of the second mounting ring 905 is fixedly connected to the second inclined block 906, and the inclined surface of the second inclined block 906 corresponds to the inclined surface of the first inclined block 904, and the second mounting ring 905 is fixedly connected to the side away from the second inclined block 906 with a cleaning sponge 907, and the fixed rod 901 and the side of the second mounting ring 905 are fixedly connected to the second inclined block 906. The side away from the first mounting ring 902 is fixedly connected to the side wall of the lower connecting frame 8, the side away from the first mounting ring 902 and the first inclined block 904 is fixedly connected with a spring 903, and the side away from the first mounting ring 902 of the spring 903 is fixedly connected to the side wall of the lower connecting frame 8, the inside of the second mounting ring 905 is rotatably connected to the outer wall of the fixed rod 901, the inside of the cleaning sponge 907 is rotatably connected to the outer wall of the fixed rod 901, and the bottom of the lower pressing block 508 corresponds to the outer wall of the second mounting ring 905;

[0041] In the present embodiment, during the cleaning process of the external curtain wall 10, the scraper 507 scrapes the outer surface of the external curtain wall 10, which causes a lot of dust to be adsorbed on the outer wall of the scraper 507. At the same time, the scraper 507 drives the pressing block 508 to move downward synchronously. When the scraper 507 slides to the bottom along the outer surface of the external curtain wall 10, the bottom of the pressing block 508 squeezes the outer wall convex corner of the second mounting ring 905. During this process, the second mounting ring 905 squeezes the first oblique block 904 through the second oblique block 906. As the second mounting ring 905 is continuously stressed, the first oblique block 904 drives the first mounting ring 902 to squeeze the spring 903. The second inclined block 906 is compressed, and the inclined surface of the second inclined block 906 will slide along the inclined surface of the first inclined block 904. After that, when the scraper 507 is close to the outer surface of the outer curtain wall 10 and is about to slide to the bottom, the second inclined block 906 will pass over the first inclined block 904, and then the spring 903 will reset, so that the second inclined block 906 and the first inclined block 904 will be re-attached together. In this process, the second mounting ring 905 will drive the cleaning sponge 907 to rotate. When the cleaning sponge 907 rotates, one side of the cleaning sponge 907 will squeeze the outer side wall of the scraper 507, and then slide in contact, so as to achieve the cleaning effect on the outer side wall of the scraper 507.

[0042] After the cleaning work is completed, the driving motor 11 rotates in the opposite direction, and then drives the cleaning mechanism 5 to reset upward. During the movement, the inner wall of the scraper 507 scrapes the outer surface of the outer curtain wall 10, and can scrape the water marks on the outer surface of the outer curtain wall 10 to avoid water stains flowing down naturally. After that, when the cleaning mechanism 5 is reset, the block 504 squeezes the inclined groove 703, so that the slide bar 701 slides and resets along the inner wall of the slide groove 6, and the through hole 702 is separated from the connecting pipe 708, so as to stop sprinkling water after the cleaning work is completed, and avoid waste of water resources;

[0043] As described above, the outer wall convex corner of the second mounting ring 905 is squeezed by the pressing block 508, so that the second mounting ring 905 drives the cleaning sponge 907 to rotate, and then one side of the cleaning sponge 907 is pressed on the outer wall of the scraper 507, and then slides in close contact, so as to scrape off the dust adsorbed on the outer wall of the scraper 507, thereby achieving the effect of cleaning the outer wall of the scraper 507 and preventing too much dust from accumulating on the outer wall of the scraper 507 and affecting the next cleaning effect.

[0044] Working principle: first, the motor 11 is driven, and the motor 11 outputs through the output shaft, and then the first gear 12 is driven to rotate, thereby driving the second gear 14 to rotate synchronously through the chain 13, and then the second gear 14 drives the screw 4 to rotate on the inner wall of the guide groove 3. Since the threaded block 501 and the screw 4 are threadedly connected, when the second gear 14 rotates, the threaded block 501 is driven to slide downward along the inner wall of the guide groove 3, and at the same time, the threaded block 501 drives the mounting plate 505 to move through the mounting frame 502, and then the mounting plate 505 drives the cleaning brush 506 and the scraper 507 to move synchronously. During the movement of the scraper 507, the end of the scraper 507 will slide against the outer surface of the outer curtain wall 10, thereby preliminarily scraping off most of the dust adsorbed on the outer surface of the outer curtain wall 10, and then during the movement of the cleaning brush 506, the end of the cleaning brush 506 will deeply clean the outer surface of the outer curtain wall 10, so that the remaining dust that the scraper 507 cannot scrape off can be deeply cleaned;

[0045] A large water tank is installed on the roof of the building and is equipped with a water pump, which is connected to the water tank through a water pipe 706 to complete the water supply for cleaning the curtain wall. While the threaded block 501 drives the installation frame 502 to move downward, the installation frame 502 drives the block 504 to move downward synchronously through the connecting plate 503. The top of the block 504 corresponds to the inside of the inclined groove 703, the outer wall of the slide rod 701 is slidably connected to the inner wall of the slide groove 6, the inner wall of the through hole 702 corresponds to the inner wall of the connecting pipe 708, the end of the connecting block 705 away from the tension spring 704 is fixedly connected to the side wall of the guide plate 2, and then the block 504 is separated from the inclined groove. When the pull spring 704 is pulled back to its original position, the slide bar 701 will slide along the inside of the slide groove 6. After the slide bar 701 has slid, the inside of the through hole 702 will be connected to the inside of the connecting pipe 708. Then the water inside the water pipe 706 will be diverted through the diverter plate 707, and then will flow into the through hole 702 through the connecting pipe 708, and then will be sprayed from the through hole 702 to the outer surface of the outer curtain wall 10. Then, in the process of cleaning the outer surface of the outer curtain wall 10 by the cleaning brush 506, the outer surface of the outer curtain wall 10 is assisted by sprinkling water. In the process of cleaning the outer curtain wall 10, The scraper 507 scrapes the outer surface of the outer curtain wall 10, which causes a lot of dust to be adsorbed on the outer wall of the scraper 507. At the same time, the scraper 507 drives the pressing block 508 to move downward synchronously. When the scraper 507 slides to the bottom along the outer surface of the outer curtain wall 10, the bottom of the pressing block 508 squeezes the outer wall convex corner of the second mounting ring 905. In this process, the second mounting ring 905 squeezes the first oblique block 904 through the second oblique block 906. As the second mounting ring 905 is continuously stressed, the first oblique block 904 drives the first mounting ring 902 to compress the spring 903. At the same time, the second oblique block The inclined surface of 906 will slide along the inclined surface of the first inclined block 904, and then when the scraper 507 is about to slide to the bottom along the outer surface of the outer curtain wall 10, the second inclined block 906 will pass over the first inclined block 904, and then the spring 903 will reset, so that the second inclined block 906 and the first inclined block 904 will fit together again. During this process, the second mounting ring 905 will drive the cleaning sponge 907 to rotate. When the cleaning sponge 907 rotates, one side of the cleaning sponge 907 will squeeze the outer side wall of the scraper 507, and then slide in contact, thereby achieving the cleaning effect on the outer side wall of the scraper 507.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
