Description

Technical Field

[0001] The present application relates to the technical field of curtain wall ventilation design, and in particular to an energy-saving external circulation building curtain wall system. Background Art

[0002] The building curtain wall refers to the non-load-bearing exterior wall enclosure of a building, which is usually composed of panels (glass, metal plates, stone slabs, ceramic plates, etc.) and the supporting structure behind it (aluminum beams and columns, steel structures, glass ribs, etc.). It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings.

[0003] Among them, the double-layer curtain wall is a new type of curtain wall composed of two glass curtain wall structures, also known as hot channel curtain wall, breathing curtain wall, ventilated curtain wall, energy-saving curtain wall, etc. Compared with the traditional closed curtain wall, its biggest feature is that a ventilation layer is formed between the inner and outer curtain walls. Due to the circulation or circulation of air in this ventilation layer, the temperature of the inner curtain wall is close to the indoor temperature. Therefore, when the room is heated or cooled, compared with the traditional curtain wall, the double-layer curtain wall can save energy for the room; in addition, due to the use of double-layer curtain walls, the sound insulation effect of the entire curtain wall has also been greatly improved.

[0004] In the prior art, the ventilation devices of double-layer curtain walls mostly use a combination of a frame and a ventilation grille, that is, a number of ventilation grilles are fixedly mounted on the outer facade of the frame. Since curtain walls are generally used in conjunction with medium and high-rise buildings, and a number of ventilation grilles are in an outdoor environment all year round, impurities are easily accumulated at the ventilation grille vents, and dust is accumulated in the ventilation layer of the double-layer curtain wall, thereby affecting the air inlet and outlet of the ventilation grille and the appearance of the double-layer curtain wall. Therefore, it is necessary to regularly perform outdoor high-altitude cleaning operations on the double-layer curtain wall, which makes the cost of later cleaning and maintenance very high, thus hindering the popularity of double-layer curtain walls. Summary of the invention

[0005] In order to improve the convenience of cleaning the air buffer layer in the double-layer curtain wall, the present application provides an energy-saving external circulation building curtain wall system.

[0006] The energy-saving external circulation building curtain wall system provided in this application adopts the following technical solutions: An energy-saving external circulation building curtain wall system comprises a mounting frame, an outer glass curtain wall and an inner glass curtain wall, wherein a hollow cavity for ventilation is surrounded between the outer glass curtain wall, the inner glass curtain wall and the mounting frame, the mounting frame comprises a top frame, a bottom frame and vertical frames on both sides, the top frame and the bottom frame are both connected to the hollow cavity on one side facing the outdoors and are provided with ventilation holes, and anti-blocking parts for unblocking the ventilation holes are slidably provided in the top frame and the bottom frame, a cleaning component for cleaning the opposite side walls of the outer glass curtain wall and the inner glass curtain wall is provided in the hollow cavity, the cleaning component comprises a roller brush part arranged in the hollow cavity along the rotation and a lifting part driving the roller brush part to slide vertically during the rotation process, the roller brush part is matched with the hollow cavity, and the roller brush part continuously scrapes the opposite inner side walls of the outer glass curtain wall and the inner glass curtain wall during the rotation process.

[0007] By adopting the above technical scheme, after long-term use, impurities are easily accumulated at the ventilation grille vents, which can easily lead to blockage of the ventilation inlet and outlet, thereby reducing the inlet and outlet air volume. By arranging anti-blocking parts in the top frame and the bottom frame and utilizing the reciprocating motion of the anti-blocking parts, the vents can be effectively prevented from being blocked, thereby ensuring the ventilation effect of the curtain wall system; dust accumulated in the hollow cavity and adhered to the opposite side walls of the outer glass curtain wall and the inner glass curtain wall will affect the light transmission effect and cleanliness of the double-layer curtain wall. The roller brush can continuously scrape the inner wall of the curtain wall during rotation, and the lifting part drives the roller brush to slide vertically at the same time, thereby realizing comprehensive and automatic cleaning of the inner wall of the curtain wall, greatly improving the cleaning efficiency and effect, and reducing the cost of cleaning and maintenance of the curtain wall in the later stage.

[0008] Optionally, the roller brush member includes a rotating shaft and a U-shaped roller brush frame coaxially fixed on the rotating shaft, and opposite sides of the two vertical frames are provided with sliding grooves in the vertical direction, and both ends of the rotating shaft are arranged in corresponding sliding grooves and slidingly cooperate with the sliding grooves, and one end of the rotating shaft is provided with a rotating wheel, and a rack is vertically arranged on the inner side wall of the sliding groove corresponding to the rotating wheel, and the rotating wheel and the rack are meshingly arranged.

[0009] By adopting the above technical solution, when the roller brush moves vertically under the guidance of the slide groove, the rotating wheel sleeved on the rotating shaft is always engaged with the rack during the lifting process, so that the roller brush frame rotates synchronously with the rotation of the rotating shaft during the lifting process, and scrapes the outer glass curtain wall and the opposite side walls of the inner glass curtain wall during the rotation process, so as to scrape off the dust adhering to the opposite side walls of the outer glass curtain wall and the inner glass curtain wall, thereby achieving a fast and efficient cleaning effect.

[0010] Optionally, the lifting member includes a limit block rotatably mounted on the other end of the rotating shaft, a screw rod vertically rotatably arranged in the sliding groove, and a driving motor driving the screw rod to rotate. The limit block is vertically slidably arranged in the sliding groove, and the screw rod rotates through the limit block through a thread.

[0011] By adopting the above technical solution, the driving motor is started to drive the screw to rotate, and the rotation of the screw drives the limit block to rotate synchronously. Due to the limitation and guidance of the slide slot, the limit block can only slide vertically in the slide slot. Due to the rotational cooperation between the rotating shaft and the limit block, when the limit block drives the rotating shaft to rise and fall, the roller brush frame rotates synchronously with the meshing rotation of the roller on the rotating shaft and the rack.

[0012] Optionally, the anti-blocking member includes a grille frame slidably arranged in the direction toward the vent and a plurality of clearing rods arranged on the side of the grille frame facing the vent, the clearing rods correspond one-to-one to the mesh holes at the vent and are plugged into each other, a limiting groove is provided on the top wall of the bottom plate of the top frame in the direction toward the vent, and a sliding block is slidably arranged in the limiting groove, the sliding block is arranged on the grille frame, and a driving member is arranged in the top frame to drive the grille frame to slide in the direction toward the vent.

[0013] By adopting the above technical solution, since the dredging rods correspond to the mesh holes at the vents one by one and are plugged together, the driving member drives the grille frame to slide back and forth in the direction of the vents, which can dredge the blocked ventilation mesh holes from time to time, effectively prevent the vents from being blocked, and improve the ventilation effect of the curtain wall system. At the same time, the through-hole setting of the grille frame helps the curtain wall to maintain a good ventilation effect during the process of dredging blockages.

[0014] Optionally, the top end of the screw rod rotates to pass through the bottom plate of the top frame and extends to the inner top wall of the top frame, and rotates in cooperation with the inner top wall of the top frame. The part of the screw rod located in the top frame is arranged in the form of a bare rod, and the driving member includes a driving gear sleeved on the end of the bare rod close to the inner top wall of the top frame, a gear plate rotatably arranged on the inner top wall of the top frame and meshing with the driving gear, and a driving rod arranged on the bottom wall of the gear plate. A guide groove is opened on the top wall of the grille frame along its own length direction, the bottom end of the driving rod is inserted in the guide groove, and the driving rod and the guide groove are slidably matched, and the gear plate drives the driving rod to make synchronous circular motion with the axis center of the gear plate as the center point during rotation, and the driving rod pushes the inner side wall of the guide groove during rotation, thereby driving the grille frame to make reciprocating motion under the limit of the limit groove.

[0015] By adopting the above technical solution, the driving motor is started to drive the screw to rotate, and the rotation of the screw synchronously drives the driving gear to rotate. Due to the meshing arrangement between the gear plate and the driving gear, the rotation of the driving gear drives the gear plate to rotate synchronously, and the gear plate drives the driving rod to perform synchronous circular motion with the axis of the gear plate as the center point during the rotation process. However, the driving rod pushes the inner wall of the guide groove during the rotation process, and the grille frame can be driven to perform reciprocating motion under the limit of the limit groove. During the reciprocating sliding process, the grille frame continuously inserts the dredging rod into the ventilation mesh, which can reduce the possibility of the ventilation mesh being blocked.

[0016] Optionally, a driven bevel gear is sleeved on the position of the light rod near the bottom wall of the top frame, a rotating rod is provided on the side of the light rod facing the room and rotates horizontally, an active bevel gear meshing with the driven bevel gear is sleeved on the end of the rotating rod, and the driving motor is arranged on the side wall of the top frame facing the room, and the output shaft of the driving motor rotates through the side wall of the top frame and extends into the top frame to be coaxially fixedly connected with the rotating rod.

[0017] By adopting the above technical solution, the driving bevel gear sleeved on the rotating rod and the driven bevel gear sleeved on the screw rod are meshed with each other, and the driving motor coaxially fixedly connected with the rotating rod is arranged on the side wall facing the room, so that the user can easily inspect and maintain the driving motor.

[0018] Optionally, an energy collection layer is provided in the hollow cavity, and the energy collection layer includes two transparent films which are heat-sealed to each other on the side of the inner glass curtain wall facing the hollow cavity, and a plurality of solar energy collectors plastic-sealed between the two transparent films, and the solar energy collectors supply energy to the drive motor.

[0019] By adopting the above technical solution, when abundant outdoor sunlight shines on the energy collection layer in the hollow cavity of the curtain wall, the several solar collectors on the energy collection layer convert the absorbed solar energy into electrical energy to supply energy to the driving motor, which drives the screw to rotate, and the screw simultaneously drives the anti-blocking parts and cleaning components to clear the vent mesh and automatically clean the dust accumulated on the inner wall of the hollow cavity of the curtain wall. In the process of cleaning the curtain wall, the cost of external power supply is saved, achieving energy-saving and high-efficiency effects.

[0020] Optionally, the transparent film facing the inner glass curtain wall is a reversible thermochromic material film.

[0021] By adopting the above technical solution, the reversible thermochromic material film pasted on the inner glass curtain wall away from the indoor side wall can change the optical properties, such as transmittance, reflectivity, etc., with the temperature of the outdoor sunlight. During the daytime when the sunlight is strong, the reversible thermochromic material film can absorb solar energy and present a dark color, reduce the penetration of sunlight, thereby reducing the indoor temperature and improving the comfort of the indoor environment; during the daytime when the sunlight is weak, the reversible thermochromic material film presents a light color close to colorless and transparent, improves the penetration of sunlight, and thus has the effect of increasing indoor lighting.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. After long-term use, impurities are easily accumulated at the ventilation grille vents, which may easily lead to blockage of the vent inlet and outlet, thereby reducing the inlet and outlet air volume. By setting anti-blocking parts in the top frame and the bottom frame and utilizing the reciprocating motion of the anti-blocking parts, the vents can be effectively prevented from being blocked, thereby ensuring the ventilation effect of the curtain wall system. Dust accumulated in the hollow cavity and adhering to the opposite side walls of the outer glass curtain wall and the inner glass curtain wall will affect the light transmission effect and cleanliness of the double-layer curtain wall. The roller brush can continuously scrape the inner side wall of the curtain wall during rotation, and the lifting part drives the roller brush to slide vertically, thereby realizing comprehensive and automatic cleaning of the inner wall of the curtain wall, greatly improving the cleaning efficiency and effect, and reducing the cost of cleaning and maintenance of the curtain wall in the later stage. 2. When the roller brush moves vertically under the guidance of the slide groove, the rotating wheel set on the rotating shaft is always engaged with the rack during the lifting process, so that the roller brush frame rotates synchronously with the rotation of the rotating shaft during the lifting process, and scrapes the outer glass curtain wall and the opposite side wall of the inner glass curtain wall during the rotation process, so as to scrape off the dust adhering to the outer glass curtain wall and the opposite side wall of the inner glass curtain wall, so as to achieve a fast and efficient cleaning effect; 3. Start the drive motor to drive the screw to rotate, and the rotation of the screw drives the limit block to rotate synchronously. Due to the limit and guidance of the slide slot, the limit block can only slide vertically in the slide slot. Due to the rotational coordination between the shaft and the limit block, when the limit block drives the shaft to rise and fall, the roller brush frame rotates synchronously with the meshing rotation of the roller and the rack on the shaft.

The bottom end of the screw rod 522 is rotatably penetrated through the top plate of the bottom frame 12 and extends to the inner bottom wall of the bottom frame 12. The part of the screw rod 522 located in the top frame 11 and the bottom frame 12 is a bare rod, and the screw rod 522 is rotatably matched with the top frame 11 and the bottom frame 12 through a bearing.

The driving motor 523 is fixedly arranged on the side wall of the top frame 11 facing the indoor room, and the output shaft of the driving motor 523 rotatably penetrates the side wall of the top frame 11, and extends into the top frame 11 to be coaxially fixedly connected with the rotating rod 8.

[0037] Reference Figure 3 and Figure 4 The anti-blocking component 6 includes a grille frame 61 and a plurality of dredging rods 62. A dovetail-shaped limiting groove 114 is provided on the top wall of the bottom plate of the top frame 11 and the bottom wall of the top plate of the bottom frame 12 along the direction toward the vent 112. A slider 611 is slidably provided in the limiting groove 114. The top wall of the slider 611 is fixedly provided on the corresponding grille frame 61. A plurality of dredging rods 62 are fixedly distributed on the side wall of the grille frame 61 facing the vent 112, and all correspond to the mesh holes at the vent 112 one by one and are plug-fitted.

[0038] Reference Figure 1 and Figure 4The top frame 11 and the bottom frame 12 are both provided with a driving member 9 for driving the grille frame 61 to slide in the direction toward the vent 112. The driving member 9 includes a driving gear 91, a gear plate 92, and a driving rod 93. Taking the top frame 11 as an example, the driving gear 91 is fixedly sleeved on the end of the light rod close to the inner top wall of the top frame 11, and the gear plate 92 is meshed with the driving gear 91 and is rotatably arranged on the inner top wall of the top frame 11. A guide groove 5121 is provided on the top wall of the frame of the grille frame 61 along its length direction, the bottom end of the driving rod 93 is inserted into the guide groove 5121, and the driving rod 93 and the guide groove 5121 are slidably matched, and the top end of the driving rod 93 is fixedly set on the gear plate 92 at an offset from the center of the circle of the gear plate 92. In this embodiment, the length of the guide groove 5121 is exactly matched with the diameter of the driving rod 93 performing synchronous circular motion with the axis of the gear plate 92 as the circle point. When the driving rod 93 rotates with the gear plate 92 to the position closest to the vent 112, the dredging rod 62 is inserted into the mesh at the vent 112. The installation method of the driving member 9 in the bottom frame 12 is the same as that in the top frame 11, but in the opposite direction.

[0039] Reference Figure 1 , Figure 3 and Figure 4 In order to improve the effect of discharging dust and dirt during the ventilation process of the curtain wall, a sewage outlet 121 is provided at the bottom of the bottom frame 12 at the bottom of the ventilation opening 112 and connected to the inner cavity of the bottom frame 12, and a cover plate 122 for covering the sewage outlet 121 is hingedly connected to the outer wall of the bottom frame 12 above the sewage outlet 121, and magnetically attracted magnets 123 are fixedly provided at both ends of the cover plate 122 along the length direction and at the opposite side of the outer wall of the bottom frame 12. During the ventilation process, the wind overcomes the magnetic attraction and brings the dust and dirt out of the curtain wall from the sewage outlet 121. When there is no ventilation, the magnetic attraction of the magnet 123 prevents external rainwater and dirt from entering the curtain wall from the sewage outlet 121.

[0040] The implementation principle of an energy-saving external circulation building curtain wall system in the embodiment of the present application is as follows: during normal use of the curtain wall, a plurality of solar collectors 413 fixed by a transparent film 411 absorb solar radiation toward the outdoors, and can convert solar energy into electrical energy and supply energy to a driving motor 523. At this time, the driving motor 523 works to drive the rotating rod 8 to rotate. Since the rotating rod 8 and the screw 522 are meshed by a bevel gear, the rotating rotating rod 8 drives the screw 522 to rotate synchronously, and the rotation of the screw 522 drives the limit block 521 in the hollow cavity 4 to rotate synchronously. However, under the restriction of the slide slot 131, the limit block 521 in the hollow cavity 4 is not rotated synchronously. The block 521 slides along the length direction of the slide groove 131, thereby driving the rotating shaft 511 set in the limit block 521 to slide vertically synchronously. Since the rotating wheel 5111 sleeved on the end of the rotating shaft 511 is directly engaged with the rack 7, the roller brush frame 512 is driven to slide vertically and rotate at the same time. During the rotation process, the roller brush frame 512 continuously scrapes the inner side walls of the outer glass curtain wall 2 and the inner glass curtain wall 3 relative to each other, and scrapes the dust and dirt on the inner wall of the glass curtain wall until it falls into the bottom frame 12. The scraped dust and dirt are blown out of the curtain wall from the sewage outlet 121 along the wind direction in the hollow cavity 4, thereby realizing automatic cleaning of the curtain wall.

[0041] The rotation of the screw rod 522 drives the driving gear 91 to rotate at the same time. Since the gear plate 92 and the driving gear 91 are meshed, the rotation of the driving gear 91 drives the gear plate 92 to rotate synchronously. During the rotation of the gear plate 92, the driving rod 93 drives the driving rod 93 to perform synchronous circular motion with the axis of the gear plate 92 as the center point. However, during the rotation of the driving rod 93, the inner wall of the guide groove 5121 is pushed, and the grill frame 61 can be driven to perform reciprocating motion under the limit of the limit groove 114. During the reciprocating sliding process, the grill frame 61 continuously inserts the ventilation mesh with the dredging rod 62, thereby pushing the obstruction blocked in the ventilation mesh out of the curtain wall, thereby achieving the anti-blocking effect of the curtain wall.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
