Description

Technical Field

[0001] This invention belongs to the field of building curtain wall technology, and specifically provides a thermal insulation and energy-saving decorative curtain wall. Background Technology

[0002] A curtain wall consists of panels and a supporting structural system. It has a certain displacement capacity relative to the main exterior structure or a certain deformation capacity, serving as both an external and decorative structure for the building. Generally, a breathing curtain wall includes an outer layer of glass and an inner layer of glass, forming a sandwich layer that can be connected to or disconnected from the external environment. When the sandwich layer is disconnected from the external environment, it increases the curtain wall's thermal insulation performance; when connected, it allows for heat exchange between the sandwich layer and the external environment, thus maintaining a better temperature difference between the interior and exterior of the building in some applications, reducing the energy consumed by additional cooling or heating inside the building.

[0003] In the relevant technical solutions, water cooling is used to achieve the cooling of the curtain wall, that is, cooling water is introduced into the interlayer through pipes. When the outside temperature is high in summer, the evaporation of cooling water in the interlayer can remove some heat, thereby reducing the amount of heat entering the room through the curtain wall, which helps to achieve energy-saving effects when cooling the indoor environment.

[0004] However, because the curtain wall requires a high degree of integration during installation and use, it is not convenient to install rainwater collection structures exposed to the outside of the curtain wall. The cooling water in this mezzanine is supplied by an indoor water tank, which makes it inconvenient to reduce reliance on additional cooling water supply by collecting external rainwater. Summary of the Invention

[0005] The purpose of this invention is to provide a thermal insulation and energy-saving decorative curtain wall that can at least solve one of the above-mentioned technical problems.

[0006] To address the aforementioned problems in the prior art, one or more embodiments of the present invention provide a thermally insulated and energy-saving decorative curtain wall, including a frame, inner glass, and outer glass. A square inner cavity is defined within the frame. The inner and outer glass are arranged opposite each other to form a sandwich layer, with their sides supported by the inner edge of the frame. The upper and lower ends of the frame have channels connecting the exterior and the sandwich layer, respectively. A slider capable of sliding along the thickness direction of the curtain wall is installed on the upper part of the frame. The upper end of the outer glass is rotatably connected to the slider via a pivot. A support block is located at the lower end of the frame, the support block having an arc-shaped support surface, the centerline of which is parallel to the width direction of the curtain wall. The lower end of the outer glass is supported by the support surface. The pivot includes a shell with an outer perforated outer periphery and a water-absorbing core embedded within the shell. A water-absorbing cavity is located on the frame, and a water-permeable hole communicating with the water-absorbing cavity is located on the support surface. A water-absorbing block is located within the water-absorbing cavity. Water-absorbing strips connecting the water-absorbing core and the water-absorbing block are located on both sides of the outer glass along its width direction.

[0007] The decorative curtain wall has two states: water absorption and evaporation. In the water absorption state, the slider moves the upper end of the outer glass and the pivot outward along the thickness direction of the curtain wall until the pivot protrudes from the frame, and the upper end of the outer glass tilts outward. In the evaporation state, the slider and the outer glass slide inward along the thickness direction of the curtain wall, the pivot is embedded in the frame, and the outer glass is arranged vertically.

[0008] Furthermore, it also includes multiple photovoltaic panels that are sequentially rotated in the interlayer along the width of the curtain wall. The slider is fixed to the crossbeam, the lower end of the photovoltaic panel is suspended, and the upper end is installed on the crossbeam. The rotation axis on the photovoltaic panel is vertically set in the middle along its width direction, and the distance between adjacent rotation axes is less than the distance between the side of the photovoltaic panel along its width direction and its own center.

[0009] The upper end of the outer glass has a first position and a second position when it is in the water absorption state. In the first position, the rotating shaft is in contact with the vertical projection of the frame. In the second position, the vertical projection of the rotating shaft and the frame does not overlap, and a water inlet is formed between the rotating shaft and the frame. When the outer glass is in the second position, every two photovoltaic panels form a photovoltaic pair. The two photovoltaic panels of each photovoltaic pair rotate around the rotating shaft to form a V-shaped structure that abuts against the outer glass. The opening of the V-shaped structure faces the inner glass, and a guide groove is formed on the inner side of the V-shaped structure.

[0010] Furthermore, the curtain wall also features two modes: a power-generating mode with vertically arranged exterior glass panels and a light-transmitting mode. In the power-generating mode, the photovoltaic panels are perpendicular to the thickness direction of the curtain wall. In the light-transmitting mode, the photovoltaic panels are parallel to the thickness direction of the curtain wall, with light-transmitting spaces formed between adjacent photovoltaic panels.

[0011] Furthermore, the photovoltaic panel has a flat pad on one side along its width and a U-shaped pad on the other side, with the U-shaped pad facing the inner glass and used to insert the flat pad.

[0012] Furthermore, there are two sliders, which are located at both ends of the curtain wall along its width. The side of the slider closest to the inner glass is fixed with a horizontal beam, and the other side is fitted with a pivot.

[0013] Furthermore, the upper and lower ends of the frame also have passageways connecting the interior and the mezzanine, and both passageways and channels can be opened and closed independently.

[0014] Furthermore, a linkage shaft is inserted through the lower end of the rotating shaft. The linkage shaft is rotatably mounted on one end of the linkage rod, and the other end of the linkage rod is rotatably connected to the lower end of the outer glass. The outer glass, rotating rod, rotating shaft, and rotating shaft are combined to form a deformable parallelogram structure.

[0015] Furthermore, it also includes a screw and a resilient reset element. The axis of the screw is parallel to the thickness direction of the curtain wall. One end of the screw passes through the inner glass, and the other end abuts against the outer glass. The resilient reset element is used to provide the pulling force for the outer glass to move into the interior to an evaporation state.

[0016] The beneficial effects of one or more of the above technical solutions:

[0017] In this design, during the water absorption phase, the outer glass can move along the thickness of the curtain wall with the slider, exposing the upper pivot and water-absorbing core of the outer glass to the outside of the curtain wall for absorbing rainwater. At this time, the lower end of the outer glass only changes its orientation by rotating; it remains supported by the curved surface at the bottom of the frame and does not protrude beyond the entire curtain wall. This allows the outer glass to tilt downwards and inwards towards the inner glass, achieving stable support for the outer glass while simultaneously guiding rainwater from the water-absorbing core to the water-absorbing block using the tilt of the outer glass in conjunction with the water-absorbing strip.

[0018] In this design, during the evaporation phase, the slider can cause the outer glass to slide in the opposite direction, thereby resetting the outer glass and the pivot, with the entire outer glass vertically arranged inside the frame. In this configuration, the outer glass and pivot are enclosed within the frame to prevent the upper part of the interlayer from directly contacting the external environment and to avoid the accumulation of dust and other contaminants inside the interlayer.

[0035] like Figures 1-11As shown, this embodiment provides a thermal insulation and energy-saving decorative curtain wall, including a frame 4, an inner glass 1, and an outer glass 6. The frame 4 defines a square inner cavity. The inner glass 1 and the outer glass 6 are arranged opposite each other to form a sandwich layer 2, with their sides supported by the inner edge of the frame 4. The upper and lower ends of the frame 4 have channels connecting the outside to the sandwich layer 2. A slider 5, capable of sliding along the thickness direction of the curtain wall, is installed on the upper part of the frame 4. The upper end of the outer glass 6 is rotatably connected to the slider 5 via a pivot 11. The lowermost end of the frame 4 has a support block with an arc-shaped support surface. The centerline of the support surface is parallel to the width direction of the curtain wall, and the lower end of the outer glass 6 is supported by the support surface. The rotating shaft 11 includes a shell with a hollowed-out outer periphery and a water-absorbing core (not shown in the figure) embedded in the shell. The frame 4 has a water-absorbing cavity 20. The inner bottom surface and the support surface of the frame have water-permeable holes (not shown in the figure) that communicate with the water-absorbing cavity 20. The water-absorbing cavity 20 has a water-absorbing block 21. The outer glass 6 has water-absorbing strips 18 on both sides along the width direction that connect the water-absorbing core and the water-absorbing block 21.

[0036] Specifically, the frame 4 here is square, comprising a horizontally arranged top frame and a bottom frame 41, with a vertical frame installed between the top frame and the bottom frame 41. The cross-sections of the top frame, bottom frame 41, and vertical frame are approximately square. The top frame, bottom frame 41, and vertical frame of the frame 4 can be integrally manufactured, or they can be manufactured separately and then fixed by angle iron or welding.

[0037] In this embodiment, the curtain wall has a first direction, a second direction, and a thickness direction that are perpendicular to each other. The first direction is arranged horizontally and serves as the width direction of the curtain wall, while the second direction is arranged approximately vertically and serves as the height direction of the curtain wall.

[0038] Specifically, the inner glass 1 and the outer glass 6 are respectively located on the inner and outer sides of the curtain wall along its thickness direction, with the inner glass 1 facing the interior of the building and the outer glass 6 facing the exterior. When the curtain wall is in evaporation mode, the outer glass 6 is approximately vertical, making the space of the interlayer 2 roughly square. The inner glass 1 and the outer glass 6 each have four sides. Taking the inner glass 1 as an example, its top side is fixed to the top frame, and its bottom side is fixed to the bottom frame 41 for support. More specifically, the outer glass 6 is fixed with a protective sleeve 61 around its perimeter, which connects the pivot 11 and the water-absorbing strip 18.

[0039] Specifically, an air outlet channel is provided on the top frame of the frame 4, and an air inlet channel is provided on the bottom frame 41. This allows outside air to enter the interlayer 2 through the air inlet channel, forming an upward cooling airflow within the interlayer 2. This airflow can carry away the heat accumulated in the interlayer 2 during hot summer months, preventing excessive heat accumulation in the double-glazed curtain wall structure and thus preventing this heat from being conducted to the indoor environment through thermal radiation. During cold winter months, by closing the air outlet and air inlet channels, the interlayer 2 can be completely isolated from the external environment, thereby reducing the probability of indoor heat dissipating to the outside through the curtain wall. In other words, the glass curtain wall in this embodiment is a breathing curtain wall structure, which facilitates the achievement of thermal insulation and energy-saving effects.

[0040] Specifically, in this embodiment, the frame 4 has a slider 5 on each side along its first direction. The frame 4 has a groove arranged along the thickness direction of the curtain wall, which penetrates the outer surface of the frame 4. The slider 5 is inserted into the groove. Two sliders 5 are respectively located on both sides of the upper end of the outer glass 6 along the first direction, and are rotatably connected to the upper end of the outer glass 6 via the aforementioned pivot 11. Specifically, after the pivot 11 passes through the support frame 62 at the upper end of the outer glass 6, both ends of the pivot 11 are rotatably connected to the two sliders 5. Preferably, the cross-section of the groove and the slider 5 can be T-shaped or dovetail-shaped to prevent the slider 5 from falling out of the groove vertically.

[0041] In this embodiment, the support block is made of elastic material such as silicone or rubber. The use of elastic material in the support block facilitates close contact between the lower part of the outer glass 6 and the support block, thereby preventing the gap between the frame 4 and the lower part of the outer glass 6 from causing unnecessary communication between the interlayer 2 and the outdoor environment. Specifically, the upper surface of the support block forms the arc-shaped support surface. With the center line of the support surface parallel to the current width direction, it ensures that the upper end of the outer glass 6 is always supported as the slider 5 slides along the thickness direction of the curtain wall and the outer glass 6 rotates around the pivot 11. This prevents the lower end of the outer glass 6 from being suspended in the air, thus avoiding the pivot 11 and slider 5 bearing excessive weight from the outer glass 6.

[0042] In this embodiment, the rotating shaft 11 is a hollow shaft, and the outer wall of the rotating shaft 11 has a plurality of hollow holes that connect to its own inner cavity. The hollow shaft of the rotating shaft 11 is filled with the water-absorbing core. The upper end of the water-absorbing strip 18 passes through the hollow hole and enters the inner cavity of the rotating shaft 11 to connect with the water-absorbing core. The water-absorbing strip 18 is inclined downward along the side of the outer glass 6, and the lower end of the water-absorbing strip 18 passes through the water-permeable hole on the support surface. The lower end of the water-absorbing strip 18 is connected to the water-absorbing block 21.

[0043] When the water-absorbing core, water-absorbing strip 18 and water-absorbing block 21 are combined, the three components can evenly distribute the rainwater absorbed at the pivot 11 within the water-absorbing core, water-absorbing strip 18 and water-absorbing block 21 for storage, preventing rainwater from splashing around in the interlayer 2 and affecting the transparency function of the curtain wall.

[0044] The decorative curtain wall has a water absorption state and an evaporation state. In the water absorption state, the slider 5 drives the upper end of the outer glass 6 and the rotating shaft 11 to slide outward along the thickness direction of the curtain wall until the rotating shaft 11 protrudes out of the frame 4 and the upper end of the outer glass 6 tilts towards the outside. In the evaporation state, the slider 5 and the outer glass 6 slide inward along the thickness direction of the curtain wall, the rotating shaft 11 is embedded in the frame 4, and the outer glass 6 is arranged vertically.

[0045] In use, during hot summer weather, when it is raining outdoors, in order to collect the rainwater and use it for evaporative cooling of the interlayer 2, the upper side of the curtain wall of the slider 5 slides. At this time, the upper end of the outer glass 6 and the rotating shaft 11 slide outward synchronously with the slider 5, thereby exposing the rotating shaft 11 above the outer glass 6 to the outside. It can absorb some rainwater from the perforated holes into the water-absorbing core during the process of being washed by rainwater, and finally guide the rainwater into the interior of the interlayer 2.

[0046] When enough rainwater accumulates in the interlayer 2, the slider 5 moves the rotating shaft 11 and the upper end of the outer glass 6 towards the interior, so that the outer glass 6 returns to its original position. At this time, the upper end of the outer glass 6 and the rotating shaft 11 are completely covered inside the frame 4, thus preventing them from being affected by external rainwater. When the rainfall stops, the air inlet and outlet channels on the frame 4 are opened. As the airflow circulates within the interlayer 2, it gradually carries away the water accumulated in the water-absorbing blocks 21, etc., within the interlayer 2. The evaporation of water vapor cools the interlayer 2 and even the entire curtain wall.

[0047] It is known that when there is heavy outdoor rainfall, the rotating shaft 11 at the upper end of the outer glass 6 can absorb enough rainwater to the interlayer 2 and complete the storage of rainwater. However, when there is light outdoor rainfall, the short-term and light rainfall is not enough to allow the interlayer 2 to accumulate enough rainwater. In order to allow the interlayer 2 to accumulate enough rainwater in light rain: In this embodiment, multiple photovoltaic panels 7 are also included, which are rotatably installed in the interlayer along the width of the curtain wall. The slider is fixed to the crossbeam, the lower end of the photovoltaic panel is suspended, and the upper end is installed on the crossbeam. The distance between adjacent rotating shafts is less than the distance between the side of the photovoltaic panel along the width direction and its own center.

[0048] The upper end of the outer glass has a first position and a second position when it is in the water absorption state. In the first position, the rotating shaft is in contact with the vertical projection of the frame. In the second position, the vertical projection of the rotating shaft and the frame does not overlap, and a water inlet 51 is formed between the rotating shaft and the frame. When the outer glass is in the second position, every two photovoltaic panels 7 form a photovoltaic pair. The two photovoltaic panels 7 of each photovoltaic pair rotate around the rotating shaft to form a V-shaped structure that abuts against the outer glass. The opening of the V-shaped structure faces the inner glass, and a guide groove 73 is formed on the inner side of the V-shaped structure.

[0049] It is known that the distance the slider 5 needs to move to the first position when the upper end of the outer glass 6 moves is L1, and the distance the slider 5 needs to move to the second position when the upper end of the outer glass 6 moves is L2, where L1 is less than L2. When the slider 5 and the upper end of the outer glass 6 move to the second position, a water inlet 51 is formed between the rotating shaft 11 and the frame 4, and this water inlet 51 can be directly introduced into the interlayer 2.

[0050] The rotation of the photovoltaic panel 7 forms multiple guide channels 73 in the interlayer 2. The guide channels 73 can smoothly guide the rainwater flowing in from the inlet 51 to the bottom of the interlayer 2, preventing rainwater from splashing everywhere and reducing the probability of rainwater splashing everywhere in the interlayer 2 onto the inner and outer glass layers and affecting light transmission.

[0051] In some embodiments, in order to make the side edges formed by adjacent photovoltaic panels 7 abut against the inner side of the outer glass 6, and thus make the guide groove 73 and the rainwater in the guide groove 73 flow downward at an angle parallel to the outer glass 6, the upper end of the rotation shaft 8 of the photovoltaic panel 7 rotates around the horizontal rotation shaft 10, so that the rotation shaft 8 is parallel to the outer glass 6.

[0052] To drive the rotation of the rotating shaft 8, a linkage shaft is installed at the lower end of the rotating shaft 8. The linkage shaft is parallel to the axis of the rotating shaft 10 and is rotatably mounted on one end of the linkage rod 22. The other end of the linkage rod 22 is rotatably connected to the lower end of the outer glass. The outer glass, the rotating rod, the rotating shaft, and the rotating shaft combine to form a deformable parallelogram structure. It is understood that, based on the above-mentioned parallelogram structure, the rotation of the outer glass 6 will cause the rotation of the rotating shaft 8, ensuring that the two remain parallel. Specifically, the rotation of the photovoltaic panel 7 relative to the rotating shaft 8 can refer to the structure of existing venetian blinds. Adjacent photovoltaic panels 7 are connected by multiple pull wires, and the tightening or loosening of the pull wires can drive the photovoltaic panels 7 to adjust their orientation. The specific connection method of the pull wires will not be elaborated here; it can be set by those skilled in the art.

[0053] Alternatively, without using the linkage rod 22, a pull wire or a micro motor can be used to drive the rotating shaft 8 to rotate around the horizontal rotating shaft 11 until the rotating shaft 8 is parallel to the inclined outer glass 8. This will not be elaborated further here.

[0054] In this embodiment, the crossbeam 19 has multiple water baffles (not shown in the figure) arranged alternately along the width direction of the curtain wall. The water baffles are used to fill the gaps between adjacent photovoltaic pairs to prevent rainwater flowing in from the inlet from flowing directly into the interlayer from the gaps between adjacent photovoltaic pairs without being guided by the guide channel 73.

[0055] In this embodiment, the curtain wall also has a power generation state and a light transmission state with the outer glass 6 arranged vertically. In the power generation state, the photovoltaic panels 7 are perpendicular to the thickness direction of the curtain wall. In the light transmission state, the photovoltaic panels 7 are parallel to the thickness direction of the curtain wall, and a light transmission space is formed between adjacent photovoltaic panels 7.

[0056] Specifically, during periods of ample sunlight, the photovoltaic panel 7, positioned perpendicular to the thickness of the curtain wall, increases the area of ​​the photovoltaic panel 7 exposed to direct sunlight, thereby improving its power generation efficiency. In the light-transmitting state, while the photovoltaic panel 7 still receives external light, its power generation efficiency decreases when not directly exposed to sunlight. However, in the light-transmitting state, more light passes through the gaps between adjacent photovoltaic panels 7 and enters the indoor environment.

[0057] In this embodiment, the photovoltaic panel 7 has a flat pad 72 on one side along its width direction and a U-shaped pad 71 on the other side. The U-shaped pad 71 faces the inner glass 1 and is used to insert the flat pad 72.

[0058] Specifically, by using the flat pad 72 and the U-shaped pad 71 together, the overlapping area of ​​the two photovoltaic panels 7 used in pairs can be tightly contacted, preventing rainwater from leaking out from that point. More specifically, the U-shaped pad 71 and the flat pad 72 can be made of elastic materials such as rubber or silicone.

[0059] In this embodiment, a crossbeam 19 is fixed to one side of the slider 5 near the inner glass 1, and a rotating shaft 11 is installed on the other side. Specifically, there is a large gap between the crossbeam 19 and the rotating shaft 11, which facilitates the formation of the aforementioned water inlet 51 between the rotating shaft 11 and the frame 4.

[0060] In this embodiment, the upper and lower ends of the frame 4 also have passages connecting the interior and the mezzanine 2, and both the passages and channels can be opened and closed independently.

[0061] Specifically, the passage at the upper end of frame 4 is the air outlet passage, and the passage at the lower end of frame 4 is the air inlet passage 17. Valves are installed on the air outlet passage and the air inlet passage 17 respectively to facilitate their independent opening and closing. The channel at the upper end of frame 4 is the air outlet channel, and the channel at the lower end of frame 4 is the air inlet channel.

[0062] In some embodiments, a micro fan is provided in the air outlet passage and the aforementioned air outlet channel 9, respectively. The micro fan is used to increase the airflow velocity in the interlayer 2, so as to better achieve the cooling of the interlayer 2.

[0063] Specifically, a vertically upward extension pipe 12 is installed on the bottom frame 401. The upper end of the extension pipe 12 is higher than the bottom frame 401, and the lower end of the extension pipe 12 is connected to the air inlet channel and the air inlet passage, respectively. With the extension pipe 12 higher than the bottom frame 401, rainwater accumulated in the interlayer 2 can be prevented from flowing back into the air inlet passage or the air inlet channel.

[0064] In this embodiment, the absorbent core, absorbent block 21, and absorbent strip 18 are all made of sponge. It is understood that using sponge facilitates diffusion along the internal pores of the sponge, thereby quickly storing the water within the interlayer 2 of the curtain wall. In other embodiments, the sponge can be replaced with cotton or other absorbent polymers, which can be determined by those skilled in the art.

[0065] In this embodiment, hollow holes are evenly distributed on both the rotating shaft 11 and the supporting surface. As one specific structural form, the hollow holes can be square or circular, as these shapes are easy to manufacture. The hollow holes can also be triangular, rhomboid, or other shapes, which can be designed by those skilled in the art.

[0066] In this embodiment, a screw 14 and an elastic reset member are also included. The axis of the screw 14 is parallel to the thickness direction of the curtain wall. One end of the screw 14 passes through the inner glass and the other end abuts against the outer glass 6. The elastic reset member is used to provide a pulling force for the outer glass 6 to move into the interior to an evaporation state.

[0067] Specifically, a nut seat is fixed on the frame 4, and a screw hole on the nut seat penetrates the inner glass 1. A screw rod 14 passes through the screw hole. A wheel 16 and a handle are installed at the indoor end of the screw rod 14, and the other end of the screw rod 14 abuts against the sheath 61 of the outer glass 6. A spring 15 is used as the elastic reset component. One end of the spring 15 is fixed to the inner side of the outer glass 6, and the other end of the spring 15 is fixed to the inner side of the frame 4. More specifically, both the spring 15 and the screw rod 14 are installed at the upper end of the curtain wall.

[0068] As can be seen, when the screw 14 moves outward to push the slider 5 away from the interlayer, the lower end of the outer glass 6 will not move outward because the lower end of the outer glass 6 is limited by the arc-shaped support surface. As a result, the upper end of the outer glass 6 will rotate around the axis 11 relative to the slider during the outward movement, thus causing the upper end of the outer glass 6 to tilt outward.

[0069] In other embodiments, where it is inconvenient to arrange the rotating wheel in the interior structure inside the curtain wall, the rotating wheel 16 and handle may not be installed at the screw 14. The screw 14 can be rotated by a micro motor and a corresponding transmission structure.

[0070] In this embodiment, multiple brackets 3 are fixed on the side of the frame closer to the interior. These brackets 3 are used to connect the curtain wall to the fixed support structure of the building's exterior wall.

[0071] The technical solutions of this application have been described in conjunction with the preferred embodiments above. However, it will be readily understood by those skilled in the art that the scope of protection of this application is not limited to the above preferred embodiments. Without departing from the technical principles of this application, those skilled in the art can disassemble and combine the technical solutions in the above preferred embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this application will fall within the scope of protection of this application.
