Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall technology, and particularly relates to a double-layer curtain wall with automatic cleaning and ventilation. Background Technology

[0002] As modern buildings develop towards high-rise and intelligent structures, double-layer curtain walls are widely used due to their aesthetic appeal and good lighting. Double-layer curtain walls are also known as thermal aisle curtain walls, breathing curtain walls, ventilated curtain walls, and energy-saving curtain walls. Double-layer curtain walls consist of two facade structures, inner and outer, forming an air buffer layer between the interior and exterior.

[0003] The existing utility model with authorization announcement number CN109083316B discloses a double-layer curtain wall, including columns installed on the main body of the building and beams installed on the columns, as well as an inner panel and an outer panel. The inner panel is sealed to the columns and beams, and the outer panel is connected to the columns and beams. The outer panel is a decorative panel.

[0004] The above technical solution serves a decorative purpose, separating the waterproof panel from the decorative panel. This ensures that sealant or sealing strips are only present on the inner panel, not the outer panel, thus improving the aesthetics of the curtain wall. However, while this solution achieves insulation in winter and heat insulation in summer, reducing energy consumption for air conditioning and making it energy-saving and environmentally friendly, the presence of dust in the air causes it to adhere to the inner surfaces of the inner and outer glass as it passes between them, making cleaning difficult. Over time, this can affect the light transmission of the curtain wall.

[0005] Therefore, we propose an automatic cleaning and ventilation type double-layer curtain wall to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that dust in the air adheres to the inner side of the inner and outer glass when passing between them, making it inconvenient to clean and affecting the light transmission effect of the curtain wall after long-term use. The invention proposes an automatic cleaning and ventilation type double-layer curtain wall.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automatic cleaning and ventilation type double-layer curtain wall includes a main frame, with two glass panels snapped into the interior of the main frame.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] Vertical downward cleaning is achieved by a first motor driving a first threaded rod, which in turn drives a first slider and a first silicone scraper. This, combined with the first through-hole, forms a natural ventilation channel for the double-layer curtain wall air layer. A second motor, via a second threaded rod, drives a second slider and a second silicone scraper to achieve horizontal bidirectional dust removal. Dust is automatically collected into the dust collection box via the guide structure of the dust collection trough. A servo motor drives a guide vane through a gear-rack-linkage mechanism to adjust its angle. This, combined with the second through-hole in the upper frame and the first airflow groove in the lower frame, forms a three-dimensional airflow circulation. The drawer-type dust collection box is equipped with a handle for tool cleaning.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 The self-cleaning and ventilation type double-layer curtain wall includes a main frame 1. Two glass panels 2 are internally snapped into the main frame 1. An upper frame 3 is fixedly connected to the upper surface of the main frame 1. A first motor 4 is fixedly connected to the bottom surface of the upper frame 3. A first threaded rod 5 is fixedly connected to the output end of the first motor 4. A first slider 6 is threadedly connected to the outer surface of the first threaded rod 5. First silicone scrapers 7 are fixedly connected to both the front and back of the first slider 6. The opposite sides of the two first silicone scrapers 7 contact the opposite sides of the two glass panels 2. Several first through holes 8 are opened on the upper surface of each first silicone scraper 7. Two second motors 9 are fixedly connected to the inner wall of the main frame 1. The output ends of the two second motors 9 are fixedly connected to... There is a second threaded rod 10, and the outer surfaces of the two second threaded rods 10 are threadedly connected to the second sliders 11. The outer surfaces of the two second sliders 11 are fixedly connected to the second silicone scrapers 12. The double glass panel 2 structure can improve the thermal insulation and sound insulation performance of the curtain wall. When the first motor 4 drives the first threaded rod 5 to rotate, it can drive the first slider 6 and the first silicone scraper 7 to move up and down, so as to achieve automatic cleaning of the inner side of the double glass panel 2. The first through hole 8 can reduce the air resistance between the scraper and the glass panel 2 during cleaning and improve the cleaning smoothness. The second motor 9 drives the second slider 11 and the second silicone scraper 12 to move through the second threaded rod 10, so as to perform targeted cleaning of the dust scraped off by the first silicone scraper 7, achieving full cleaning coverage.

[0027] A lower frame 13 is fixedly connected to the bottom surface of the main frame 1. A servo motor 14 is fixedly connected to the inner wall of the lower frame 13. A gear 15 is fixedly connected to the output end of the servo motor 14. A rack 16 is meshed with the outer surface of the gear 15. Several connecting rods 17 are movably connected to the right side of the rack 16. A guide vane 18 is fixedly connected to the outer surface of each connecting rod 17. A rotating shaft 19 is rotatably connected inside each guide vane 18. When the servo motor 14 drives the gear 15 to rotate, the guide vane 18 can be driven to rotate around the rotating shaft 19 through the transmission between the rack 16 and the connecting rod 17, so as to realize the angle adjustment of the guide vane 18, thereby flexibly controlling the airflow inside and outside the curtain wall and meeting the ventilation needs in different scenarios. Since the servo motor 14 has a built-in encoder and brake, when the servo motor 14 stops rotating, it will automatically lock the output shaft, so as not to cause the rack 16 to fall under its own weight.

[0028] Two dust collection troughs 20 are provided on the inner wall of the main frame 1. Two second silicone scrapers 12 are slidably connected inside the dust collection troughs 20. The dust collection troughs 20 can collect the dust cleaned by the first silicone scraper 7 in a concentrated manner to avoid dust scattering and causing secondary pollution. At the same time, they provide sliding guidance for the second silicone scraper 12 to ensure the stability of the cleaning path.

[0029] The bottom surface of the upper frame 3 is provided with several second through holes 21, and the front and back of the upper frame 3 are provided with several first air flow grooves 22. The second through holes 21 can connect the interior of the upper frame 3 with the space between the double glass panels 2, and together with the first air flow grooves 22, form an airflow channel that runs through the upper and lower parts, thereby improving the natural ventilation efficiency of the curtain wall and enhancing the indoor and outdoor air circulation effect.

[0030] The main frame 1 has a sliding connection to a dust collection box 23. A handle 24 is fixedly connected to the back of the dust collection box 23. The dust collection box 23 is connected to the dust collection trough 20. The dust collected in the dust collection trough 20 can be driven by the second motor 9 to drive the second threaded rod 10, which in turn drives the second slider 11 and the second silicone scraper 12 to move, so that the scraped dust falls into the dust collection box 23. The dust collection box 23 can be easily pulled out for cleaning through the handle 24 without disassembling the curtain wall structure, which reduces the difficulty of maintenance.

[0031] The back of the lower frame 13 is provided with several second air flow slots 25. Each second air flow slot 25 is fixedly connected to a filter screen 26 on its inner wall. The second air flow slots 25 and the first air flow slots 22 of the upper frame 3 cooperate to form a complete ventilation path. The filter screen 26 can filter the incoming air, block dust, impurities and other contaminants from entering the room, and ensure the cleanliness of the ventilated air.

[0032] Two brackets 27 are fixedly connected to the inner wall of the lower frame 13. Each rotating shaft 19 is snapped into the inside of the bracket 27. The bracket 27 provides stable support for the rotating shaft 19, preventing the guide vane 18 from shaking under adjustment or airflow impact, and ensuring the stability of ventilation regulation.

[0033] The front of the lower frame 13 is fixedly connected to two emergency through-hole plates 28. Each of the two emergency through-hole plates 28 has several third through holes 29 on its front. The emergency through-hole plates 28 and the third through holes 29 can serve as backup ventilation paths when the main ventilation channel fails, ensuring the safety of indoor air circulation and improving the emergency protection capability of the curtain wall.

[0034] The working principle of this utility model is as follows: In use, firstly, the first motor 4, the second motor 9, and the servo motor 14 are connected to an external power supply and a controller. The first motor 4 inside the upper frame 3 is then started. The first motor 4 drives the first threaded rod 5 to rotate, which in turn drives the first slider 6 to move up and down along the length of the threaded rod via threaded transmission. This, in turn, causes the first silicone scrapers 7 on the front and back of the first slider 6 to move synchronously. Because the first silicone scraper 7 is in close contact with the opposite sides of the two glass plates 2, it can scrape away dust and stains on the inner side of the glass plates 2 during movement. Simultaneously, the first through-hole 8 on the first silicone scraper 7 reduces air resistance during scraper movement, preventing scraper deviation due to airflow impact and ensuring the stability of the cleaning trajectory. When the silicone scraper 7 moves to the lowest point on the opposite side of the two glass plates 2, the second motor 9 on the inner wall of the main frame 1 is activated. The second motor 9 drives the second threaded rod 10 to rotate, causing the second slider 11 and the second silicone scraper 12 to move along the threaded rod direction. This allows for targeted cleaning of the dust scraped off by the first silicone scraper 7, achieving full cleaning coverage. At this time, the dust collection groove 20 on the inner wall of the main frame 1 provides a sliding guide for the second silicone scraper 12 and collects the dust scraped off by the scraper. The dust moves through the second silicone scraper 12 and falls into the connected dust collection box 23 via the dust collection groove 20. The dust collection box 23 can be pulled out by the handle 24 for centralized cleaning to avoid secondary dust pollution. The servo motor 14 in the lower frame 13 is then activated, driving the second slider 11 and the second silicone scraper 12 to move along the threaded rod direction. Gear 15 rotates, driving rack 16 to move horizontally through meshing. Rack 16, via connecting rod 17, pushes several guide vanes 18 to rotate around shaft 19, adjusting the tilt angle of the guide vanes 18. Shaft 19 is stably supported by bracket 27 on the inner wall of lower frame 13 to prevent guide vanes 18 from wobbling. When the angle of guide vanes 18 is adjusted to the appropriate position, the second through hole 21 on the bottom of upper frame 3 connects the interior of upper frame 3 with the space between the two glass plates 2. This, together with the first airflow grooves 22 on the front and back of upper frame 3 and the second airflow groove 25 on the back of lower frame 13, forms a vertically connected airflow channel: outdoor air enters through the second airflow groove 25 of lower frame 13 and passes through filter 26. After filtering out dust and impurities, the air flows upward under the guidance of the guide vane 18, and is discharged to the outside through the gap between the two glass plates 2, the second through hole 21 of the upper frame 3 and the first air flow channel 22, completing the indoor and outdoor air circulation. By adjusting the angle of the guide vane 18, the airflow resistance can be changed, thereby precisely controlling the ventilation volume to meet the ventilation needs of different scenarios. When the main ventilation channel cannot ventilate normally due to a malfunction, the emergency through hole plate 28 on the front of the lower frame 13 can serve as a backup ventilation path. The third through hole 29 on the emergency through hole plate 28 can achieve air circulation, ensuring that the indoor air can still maintain basic air circulation when the main ventilation system fails, avoiding the decline in indoor air quality due to ventilation interruption, and improving the safety and reliability of the curtain wall.
