Description

Technical Field

[0001] The present invention relates to the technical field of glass curtain walls, and in particular to a multi-component assembled glass curtain wall with ventilation, sunshade and green environmental protection functions. Background Art

[0002] Energy conservation, environmental protection, and sustainable development are currently the core themes of architectural development. As a key decorative and protective structure for high-rise building facades, glass curtain walls, with their unique aesthetics and excellent lighting performance, have become the mainstream choice for high-rise building facade design. However, with increasing attention to building environmental quality, energy conservation and emission reduction, and sustainable development, existing glass curtain walls have exposed many urgent issues in ventilation, shading, and environmental protection.

[0003] For example, traditional glass curtain walls are mostly enclosed structures, relying primarily on mechanical ventilation systems for indoor and outdoor air circulation. This approach not only increases building energy consumption but also, in certain situations, such as mechanical ventilation equipment failure or power outages, can make indoor air quality difficult to maintain. Even if some glass curtain walls feature openable sashes, the limited opening area results in poor ventilation, making it difficult to meet the fresh air needs of indoor residents.

[0004] In terms of sunshade, currently common sunshade measures include external sunshades and blinds. External sunshades are easily damaged in strong winds, and the sunshade effect is greatly affected by the installation angle and position. Although blinds can adjust the sunshade angle to a certain extent, in actual use, the blades are prone to dust accumulation and difficult to clean and maintain. In addition, their method of blocking sunlight is relatively simple and cannot be intelligently adjusted according to the intensity of sunlight at different times. For example, when the sun is strong, the room will still be exposed to excessive solar radiation, causing overheating. When light is needed, excessive sunshade may affect the indoor lighting effect. Based on this, we propose a multi-faceted prefabricated glass curtain wall with ventilation and sunshade functions to effectively solve the above-mentioned drawbacks. Summary of the Invention

DETAILED DESCRIPTION

[0044] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] Example 1: Please refer to Figure 1 - Figure 5 A multi-assembly glass curtain wall with ventilation, sunshade and green environmental protection functions includes a longitudinal keel 100, a transverse keel 200 and a plurality of glass curtain wall bodies 300. The number of the longitudinal keels 100 and the transverse keels 200 is several, and the longitudinal keels 100 and the transverse keels 200 are staggered to form a plurality of rectangular installation intervals. The glass curtain wall bodies 300 correspond to the installation intervals one by one and are fixedly arranged in the corresponding installation intervals.

[0046] It should be noted that the longitudinal keel 100 and the transverse keel 200 are both made of aluminum alloy, and are connected to the outer wall of the building through fixings. The cross-sections of the longitudinal keel 100 and the transverse keel 200 are both T-shaped, and the inner end faces of the two are flush with each other.

[0047] In addition, connectors 600 are molded into the left and right sidewalls of the longitudinal purlins 100 and the upper and lower sidewalls of the transverse purlins 200. The glass curtain wall body 300 includes an inner layer of glass 301 and an outer layer of glass 302. The inner layer of glass 301 is fixedly connected to the longitudinal purlins 100 and transverse purlins 200, while the outer layer of glass 302 is fixedly connected to the connectors 600. It should be noted that the glass is bonded to the purlins or connectors 600 using glass adhesive. Mounting holes are pre-drilled in the glass, and bolts are screwed into the mounting holes to secure the glass. Furthermore, the spacing between the inner and outer layers of glass 301 and 302 is between 100 and 500 mm. The outer layer of glass 302 is Low-E glass to reduce indoor temperature.

[0048] Furthermore, a wind direction sensor 400 and a controller 500 are provided on the longitudinal keel 100, and the signal output end of the wind direction sensor 400 is connected to the controller 500; specifically, there is a notch on the longitudinal keel 100 and located on the outside of the glass curtain wall body 300, the wind direction sensor 400 is arranged in the notch, and the controller 500 is arranged on the inside of the longitudinal keel 100; the wind direction sensor 400 is used to monitor the wind direction of the external environment in real time and transmit the information to the controller 500 in a timely manner.

[0049] In order to achieve the ventilation effect of the glass curtain wall, this embodiment has the following designs:

[0050] Ventilation holes 101 are provided on both side walls of the longitudinal keel 100 and on the outer side of the glass curtain wall body 300. A number of exhaust vents 102 are provided on the inner end surface of the longitudinal keel 100, that is, the exhaust vents 102 are located on the indoor side. Ventilation components 103 are provided in the two vents 101. The signal output end of the controller 500 is connected to the ventilation component 103 for controlling the action of the ventilation component 103 to open and close the vents 101. Specifically, when the wind direction is not perpendicular to the glass curtain wall, the ventilation component 103 on the side facing the vent is in an expanded state, and the ventilation component 103 on the side facing away from the vent is in a closed state. When the wind direction is perpendicular to the glass curtain wall, both ventilation components 103 are in an expanded state, so that external air can enter the room to a greater extent.

[0051] It should be noted that when the angle between the wind direction detected by the wind direction sensor 400 and the vertical line of the glass curtain wall does not exceed 10 degrees, the wind direction is considered to be perpendicular to the glass curtain wall. In addition, an insect screen is also provided at the exhaust vent 102 to prevent external mosquitoes or large particles of impurities from entering the room.

[0052] Therefore, in specific applications of this embodiment, the vents 101 located on both sides of the longitudinal keel 100 can be automatically opened in a timely manner according to the dynamic changes in wind direction, ensuring that the airflow can always flow smoothly into the room, greatly promoting the circulation and flow of indoor air.

[0053] Example 2: Please refer to Figure 1 - Figure 5 The embodiment of the present application also provides a multi-element prefabricated glass curtain wall with ventilation, sunshade and green environmental protection functions. Compared with the first embodiment, the longitudinal keel 100 of this embodiment is further provided with a light intensity sensor 104, and the signal output end of the light intensity sensor 104 is connected to the controller 500. When the outdoor light intensity exceeds the threshold of the light intensity sensor 104, both ventilation components 103 are in the closed state. The light intensity sensor 104 is also provided inside the longitudinal keel 100, and the detection end of the light intensity sensor 104 extends outside the longitudinal keel 100. In other words, the light intensity sensor 104 can monitor the changes in the external light intensity in real time and transmit the signal to the controller 500 in real time.

[0054] It should be noted that the light intensity signal has a higher priority than the wind direction signal. That is, when the outdoor light intensity exceeds the threshold of light intensity sensor 104, both ventilation assemblies 103 are necessarily closed. This serves to prevent high-temperature airflow from entering the room during summer or hot weather. When the outdoor light intensity does not exceed the threshold of light intensity sensor 104, controller 500 will open both ventilation assemblies 103 as appropriate based on the wind direction signal.

[0055] In addition, an electric sunshade mechanism 303 is provided between the inner glass 301 and the outer glass 302, and the signal output end of the controller 500 is connected to the electric sunshade mechanism 303; when the outdoor light intensity exceeds the threshold of the light intensity sensor 104, the controller 500 controls the electric sunshade mechanism 303 to operate and put it in a sunshade state.

[0056] Compared with the first embodiment, this embodiment adds a light intensity sensor 104 as a signal source for determining whether the vent 101 is open or closed. The advantage of this embodiment is that when the outdoor light intensity is high, the vent 101 can automatically close, thereby preventing external airflow from entering the room through the vent 101. In addition, when the outdoor light intensity is high, the electric sunshade mechanism 303 automatically unfolds the sunshade, which can also prevent strong external light from shining into the room, further preventing the indoor temperature from rising, thereby helping to reduce the energy consumption of the indoor air conditioner and achieve a green and environmentally friendly effect.

[0057] Example 3: Please refer to Figure 1 - Figure 9The embodiment of the present application also proposes a multi-faceted prefabricated glass curtain wall with ventilation, sunshade and green environmental protection functions. The difference between this embodiment and the second embodiment is that: the ventilation component 103 includes a plurality of ventilation plates 1031 arranged at intervals in the horizontal direction, and the ventilation plates 1031 rotate with the inner wall of the vent 101 through the rotating shafts 1032 at the upper and lower ends thereof; the ventilation component 103 also includes a ventilation drive component for controlling the synchronous rotation of the plurality of ventilation plates 1031 to realize the opening and closing of the vent 101.

[0058] Specifically, an adjustment port 105 is provided on the inner wall of the longitudinal keel 100 and below the vent 101, and the rotating shaft 1032 at the bottom end of the vent plate 1031 extends into the adjustment port 105. An adjustment shaft 1033 is also vertically provided on the rotating shaft 1032 at the bottom end of the vent plate 1031, and an opening is passed through the adjustment shaft 1033; the ventilation drive assembly includes a displacement block 1034 and two electromagnets 1035, the displacement block 1034 is movably connected to the inner wall of the longitudinal keel 100, the two electromagnets 1035 are respectively located on both sides of the displacement block 1034, and a horizontal shaft 1036 is also provided on the top of the displacement block 1034, and a drive shaft 1037 corresponding to the adjustment shaft 1033 is provided on the horizontal shaft 1036, and several drive shafts 1037 respectively pass through the openings on the corresponding adjustment shafts 1033; when the two electromagnets 1035 are alternately energized, the vent 101 is respectively in a closed or open state.

[0059] It should be noted that the electromagnets 1035 are electrically connected to the built-in power supply of the longitudinal keel 100, and the controller 500 controls the power on and off of the two electromagnets 1035 through the control circuit, thereby controlling the left and right translation of the displacement block 1034 to drive the rotation of the ventilation fins 1031. It is worth mentioning that when the ventilation assembly 103 is in the open state, the ventilation fins 1031 are all tilted and have the function of guiding outdoor airflow into the room.

[0060] Furthermore, an exhaust duct 106 is rotatably mounted at the exhaust port 102. Inside the exhaust duct 106, a number of obliquely spaced, louver-like air guide vanes 107 are positioned. An exhaust drive assembly is also located within the longitudinal keel 100 to control the rotation of the exhaust duct 106 and thereby change the direction of exhaust. Due to the oblique arrangement of the air guide vanes 107, they also serve to guide the airflow.

[0061] Specifically, the exhaust drive assembly includes a number of driven gear rings 108 mounted on the outside of the exhaust duct 106 and an electric slide 109 fixedly mounted on the inner wall of the longitudinal keel 100. The movable end of the electric slide 109 is provided with an active rack 110. The driven gear ring 108 is engaged with the active rack 110, and the signal output end of the controller 500 is connected to the electric slide 109. When the electric slide 109 drives the active rack 110 to move, it can indirectly control the rotation of the exhaust duct 106, thereby changing the exhaust direction.

[0062] Since both the exhaust direction and the air inlet direction are controlled by the controller 500, in order to allow external air to enter the room more smoothly, when the ventilation component 103 on the left side of the longitudinal keel 100 is unfolded, the controller 500 controls the air outlet direction of the air guide plate 107 to point to the right; when the ventilation component 103 on the right side of the longitudinal keel 100 is unfolded, the controller 500 controls the air outlet direction of the air guide plate 107 to point to the left; when both ventilation components 103 are unfolded, the controller 500 controls the air outlet direction of the air guide plate 107 to point downward.

[0063] For example, when the ventilation assembly 103 located on the left side of the longitudinal keel 100 is unfolded, Figure 8 As shown, external air typically blows into the interior of the longitudinal keel 100 at an angle from left to right. In this airflow state, precisely adjusting the outlet direction of the air guide 107 to point to the right cleverly aligns with the airflow. This allows air to flow more smoothly and efficiently into the curtain wall, following the direction of the air guide 107. This reduces resistance and turbulence during airflow entry, ensuring stable ventilation.

[0064] However, when the two ventilation components 103 are deployed simultaneously, the situation changes significantly. At this time, external air flows in from both sides of the longitudinal keel 100, and the airflow direction is almost perpendicular to the glass curtain wall, forming a large airflow volume. In this high airflow environment, if the air continues to blow directly into the room in a horizontal direction, it is very likely to interfere with the activities and comfort of the people indoors. Therefore, adjusting the air outlet direction of the air guide 107 to point downward can effectively change the airflow trajectory, allowing the air to enter the indoor space in a more gentle manner, avoiding the discomfort caused by direct blowing, and ensuring a stable and comfortable indoor environment.

[0065] In other embodiments of the present application, the plurality of exhaust vents 102 are arranged vertically at intervals, and the active rack 110 is also arranged vertically. The maximum travel of the active rack 110 is greater than the distance between the two farthest exhaust vents 102. When the active rack 110 is at the bottommost position, the active rack 110 and the plurality of driven ring gears 108 are all engaged. At this time, the inclination directions of the air guide vanes 107 in the plurality of exhaust vents 102 are consistent. That is, as the active rack 110 moves, the plurality of exhaust tubes 106 can move synchronously to change the exhaust direction.

[0066] As the active rack 110 continues to rise from the bottom position, it gradually separates from the driven ring gear 108 at the bottom, until the active rack 110 reaches the topmost position, at which point the active rack 110 is separated from all the driven ring gears 108. Because each exhaust duct 106 rotates a different number of times during the ascending process of the active rack 110, the exhaust directions of the exhaust ducts 106 are also different. Specifically, in this embodiment, when the active rack 110 reaches the topmost position, the exhaust ducts 106 discharge air in different directions, up, down, left, and right, respectively, to ensure that external air enters the indoor space more evenly.

[0067] In addition, the wind direction sensor 400 can be an integrated wind speed and direction sensor that can detect both wind direction and wind speed. When the outdoor wind speed exceeds the sensor's wind speed threshold, it indicates that the external wind speed is relatively high. Therefore, the active rack 110 can be raised to its topmost position, causing the multiple exhaust vents 102 to discharge air in different directions.

[0068] In addition, in different embodiments of the present application, a soil-free and maintenance-free plant shading module 700 is provided between the inner glass 301 and the outer glass 302, such as Figure 10 As shown, the soil-free, maintenance-free plant shading module 700 includes a planting frame and an irrigation system. The planting frame houses green plants, and the irrigation system is connected to the outside through pipes, allowing workers to provide water and nutrients to the plants. Furthermore, the air layer between the two layers of glass is connected to the longitudinal keel to ensure that air can enter the air layer.

[0069] This embodiment also has a photovoltaic power generation module, which includes flexible thin-film solar cells. The solar cells are attached to the inner surface or outer surface of the outer glass 302 and are used to convert light energy into electrical energy, thereby powering indoor electrical appliances and achieving energy-saving and environmental protection effects.

[0070] In summary, this embodiment utilizes soil-free, maintenance-free plant shading modules 700 to add green vitality to the building, improving the indoor and outdoor environments and enhancing the building's aesthetics. Furthermore, photovoltaic power generation modules convert solar energy into electricity, providing clean energy for the building and achieving energy conservation and emission reduction. Furthermore, the glass curtain wall body 300, longitudinal keels 100, and transverse keels 200 all utilize detachable connections. This modular design facilitates installation, maintenance, and replacement, enhancing the maintainability and scalability of the curtain wall system.
