Description

Technical Field

[0001] The invention relates to the field of curtain wall cleaning, and more particularly to a glass curtain wall with a self-cleaning function. Background Art

[0002] Glass curtain walls are commonly used in some high-rise buildings. They are widely used due to their advantages of beauty, practicality and good lighting. However, as an outdoor wall, glass curtain walls at high altitudes are more susceptible to pollution. Dust, haze, sandstorms and bird excrement in the air will gradually settle on the surface of the curtain wall, thus affecting the overall appearance and light transmittance of the glass curtain wall. For this reason, the glass curtain wall needs to be cleaned regularly.

[0003] Operators should wear protective equipment such as safety helmets, non-slip shoes, and safety belts to ensure their own safety. Operators should be hoisted to the working position by external hoisting equipment, and fasten the safety belts and self-locking devices. Glass scrapers and water wipers should be used with detergents for deep cleaning to ensure that every glass surface can be fully cleaned;

[0004] Glass curtain walls are usually located outside of buildings, and cleaning work needs to be done at high altitudes. External cleaning of glass curtain walls requires the use of professional equipment and tools, such as hanging baskets, hanging boards, cleaning agents, etc. Since the cleaning work needs to be done by professionals and usually needs to be done at high altitudes, however, due to the particularity of high-altitude operations, environmental factors such as wind and temperature may pose a threat to the safety of workers.

DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] like Figure 1 - Fig. 9 As shown, a glass curtain wall with a self-cleaning function comprises: a curtain wall transverse frame 11, a curtain wall longitudinal frame 12 is arranged on the curtain wall transverse frame 11, a double-layer glass 13 is fixedly arranged between the curtain wall longitudinal frame 12 and the curtain wall transverse frame 11, and an outer wall decontamination mechanism 2 for scraping the outer surface of the glass is arranged between two adjacent curtain wall longitudinal frames 12 on the outer surface of the double-layer glass 13;

[0033] The outer wall dirt removal mechanism 2 includes a scraper, a guide and an inner control unit, which are connected to each other. The scraper is pulled by the inner control unit to move up and down along the guide on the outer surface of the double-layer glass 13, so that the scraper scrapes and wipes the outer surface of the double-layer glass 13 according to the rise and fall;

[0034] The inner control unit is arranged in the curtain wall longitudinal frame 12 on one side of the double-layer glass 13 and is connected to the scraping member for scraping the double-layer glass 13 in the same row.

[0035] Through mechanized means, that is, turning the internal control to drive the scraper to slide along the guide, a large area of ​​glass curtain wall cleaning can be completed quickly, which is more efficient than the traditional manual cleaning method. Since the cleaning work is completely carried out inside the building, the safety risks brought by high-altitude operations, such as falling, being blown off by the wind, etc., are avoided, which greatly ensures the safety of cleaning personnel;

[0036] Depending on the direction in which the scraper slides up or down, the two functions of light brushing and scraping are integrated into one, which reduces the need to change tools during cleaning, thereby improving cleaning efficiency. Cleaning staff do not need to frequently switch tools between light brushing and scraping, but only need to control the sliding of the scraper.

[0037] The scraper includes a rubbing plate 21 parallel to the double-layer glass 13. Both ends of the rubbing plate 21 are provided with guide plates 22 slidably connected to the curtain wall longitudinal frame 12. The two guide plates 22 are provided with guide grooves 25 on one side close to the rubbing plate 21. The height of the guide grooves 25 gradually decreases from the double-layer glass 13 to the outside.

[0038] A slider 26 fixedly connected to the wiping plate 21 is slidably provided inside the guide groove 25, and a guide rail 27 parallel to the guide groove 25 is penetrated inside the slider 26. A guide plate 23 is fixedly provided between two curtain wall longitudinal frames 12 adjacent to the upper wall of the curtain wall transverse frame 11. A plurality of drainage holes 24 are opened on the side wall of the guide plate 23, and the guide plate 22 slides down into the guide plate 23 through the slider 26 and the guide rail 27.

[0039] A limiting groove 41 is provided on one side of the wiping plate 21 close to the outer surface of the double-layer glass 13, and a scraping rubber strip 42 is rotatably arranged inside the limiting groove 41. The scraping rubber strip 42 has a crescent-shaped structure, and a plurality of brush bundles 43 are fixedly arranged on the bottom edge of the scraping rubber strip 42. The crescent tip of the scraping rubber strip 42 protrudes from the side wall of the wiping plate 21.

[0040] A semi-cylindrical limit strip 44 is fixedly provided at the ridge position of the scraping rubber strip 42, and inflation air strips 45 are fixedly provided on the upper and lower walls of the limit strip 44. The air inlet ends of the two inflation air strips 45 are respectively connected to airbag 1 48 and airbag 2 49 through hoses, and an extrusion plate 47 slidably connected to the guide plate 22 is provided between airbag 1 48 and airbag 2 49. A control column 46 that passes through airbag 1 48, airbag 2 49 and guide plate 22 in sequence is fixedly provided at the center position of the extrusion plate 47.

[0041] When the guide plate 22 slides downward, the squeezing plate 47 is in a state of squeezing the airbag 48. The air in the airbag 48 enters the expansion air strip 45 below the limit strip 44 through the hose and expands it. The expansion of the expansion air strip 45 pushes the scraping rubber strip 42 to rotate clockwise by a certain angle, so that the crescent tip of the scraping rubber strip 42 with the brush bundle 43 is tightly attached to the outer surface of the double-layer glass 13. As the scraping rubber strip 42 rises, it cooperates with the cleaning liquid to gently wipe the outer surface of the double-layer glass 13.

[0042] When the guide plate 22 rises to the highest end, the control column 46 will be squeezed, causing the squeezing plate 47 to squeeze the airbag 2 49, and the air in the airbag 2 49 enters the expansion gas strip 45 above the limit strip 44 through the hose, causing it to expand. Under the push of the expansion gas strip 45, the scraping strip 42 rotates counterclockwise by a certain angle, so that the crescent tip of the scraping strip 42 without the brush bundle 43 is tightly attached to the outer surface of the double-layer glass 13, and as the scraping strip 42 slides downward, all the stains and cleaning fluid wiped off by the brush bundle 43 can be scraped away.

[0043] The guide member includes a guide column 31 which is vertically fixed between two adjacent curtain wall horizontal frames 11 and is passed through the center of two guide plates 22. A lifting groove 34 is opened inside the guide column 31. The guide plate 22 slides along the guide column 31 through the lifting groove 34. A bottom plate 32 is fixedly provided at the bottom of the guide column 31. A magnetic strip 2 33 is fixedly provided on the side wall of the bottom plate 32. A magnetic strip 1 28 is fixedly provided on the side of the wiping plate 21 away from the outer surface of the double-layer glass 13, and the magnetic strip 1 28 and the magnetic strip 2 33 attract each other.

[0044] The guide plate 22 is pulled up by two steel cables 29 at the same time, driving the guide plate 22 to slide upward, and at the same time, the wiping plate 21 is pulled out of the guide plate 23 through the guide plate 22, so that the magnetic strip 1 28 is separated from the suction of the magnetic strip 2 33. At this time, the spring is wound around the guide rail 27 to push the wiping plate 21 to slide and contact the outer surface of the double-layer glass 13. Afterwards, when the wiping plate 21 moves upward or downward, it plays a role in cleaning the outer surface of the double-layer glass 13.

[0045] The internal control includes a guide cross column 35 fixedly connected to the inside of the curtain wall longitudinal frame 12. Two identical and symmetrical pull-wire blocks 36 are slidably arranged on the guide cross column 35. The two pull-wire blocks 36 are both slidably connected to the curtain wall longitudinal frame 12. In the initial state, the two pull-wire blocks 36 are respectively located at the two ends of the guide cross column 35.

[0046] A steel cable 29 is fixedly installed on one side of the two pull-wire blocks 36 close to the guide column 31 on the same side. The end of the steel cable 29 away from the pull-wire block 36 passes through the lifting groove 34 and is fixedly connected to the guide plate 22. A steel cable 2 37 is also fixedly installed on one side of the two pull-wire blocks 36 away from the guide column 31 on the same side.

[0047] A steel wire main cable 38 that runs through multiple curtain wall longitudinal frames 12 in the same row is fixedly provided at one end of the steel wire cable 2 37 away from the pull wire block 36, a pulling-up reel 39 that is rotatably connected to the highest curtain wall transverse frame 11 is fixedly provided at the top of the steel wire main cable 38, a winding spring 301 is fixedly provided inside the pulling-up reel 39, a pulling-down reel 302 that is rotatably connected to the lowest curtain wall transverse frame 11 is fixedly provided at the bottom end of the steel wire main cable 38, and an elastic band 201 is fixedly provided on one side of the guide plate 22 away from the steel wire cable 1 29.

[0048] A liquid injection head 51 is fixedly arranged on the curtain wall cross frame 11 on one side of the pull-down reel 302, and the output end of the liquid injection head 51 is connected to a water outlet hose distributed at the edge of the curtain wall cross frame 11 on one side of the outer surface of each double-layer glass 13, which is used to inject cleaning liquid from the liquid injection head 51 and spray it onto the outer surface of the double-layer glass 13 through the water outlet hose.

[0049] When the glass curtain wall installed outside the building needs to be cleaned, the staff first needs to inject the cleaning liquid from the liquid injection head 51, and the cleaning liquid is sprayed onto the outer surface of the double-layer glass 13 along the interconnected water outlet hoses, so that the cleaning liquid flows from top to bottom;

[0050] After that, the staff only needs to rotate the pull-down reel 302 inside the building, and reel the wire main cable 38 by rotating the pull-down reel 302, so as to pull the multiple sets of wire cables 2 37 at different positions in the same column at the same time through the wire main cable 38, and pull the two wire pulling blocks 36 to slide along the guide cross column 35 in different directions at the same time through the wire cables 2 37. When the two wire pulling blocks 36 slide to the other end at the same time, the wire cables 1 29 on the two guide plates 22 are pulled at the same time, thereby driving the two guide plates 22 to slide upward in the same direction and at the same speed, and the sliding of the guide plates 22 drives the light wiping plate 21 to slide upward along the outer surface of the double-layer glass 13;

[0051] Finally, after the staff has finished cleaning the outer surface of this row of double-layer glass 13, the two guide plates 22 are pulled down along the guide column 31 through the pull-back elasticity of the elastic band 201, so that the wiping plate 21 slides into the guide plate 23, and the elasticity of the winding spring 301 drives the lifting reel 39 to rewind the wire main cable 38.

[0052] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
