Description

Technical Field

[0001] The invention belongs to the technical field of building curtain walls, and specifically provides a thermal insulation and energy-saving decorative curtain wall. Background Art

[0002] The curtain wall is composed of panels and a supporting structure system. It has a certain displacement capability relative to the main structure of the exterior wall or a certain deformation capability itself, so as to serve as the building's external structure and decorative structure. Generally, a breathing curtain wall includes an outer layer of glass and an inner layer of glass, with a sandwich layer formed between the two, which can be connected or disconnected from the external environment. When the sandwich layer is disconnected from the external environment, the thermal insulation performance of the curtain wall can be increased; when the sandwich layer is connected to the external environment, it can achieve heat exchange between the sandwich layer and the external environment, thereby maintaining a better temperature difference between the inside and outside of the building in some application scenarios, reducing the energy consumed by additional cooling or heating inside the building.

[0003] In the related technical scheme, water cooling is used to achieve water cooling of the curtain wall, that is, cooling water is passed into the interlayer through a pipeline. In summer, when the outside temperature is high, the evaporation of cooling water in the interlayer can take away some heat, thereby reducing the heat entering the room through the curtain wall, which is beneficial to achieve energy-saving effect when cooling the indoor environment.

[0004] However, because the curtain wall needs to have strong integrity during installation and use, it is not convenient to arrange a rainwater collection structure exposed outside the curtain wall. The cooling water in the interlayer is provided by an indoor water tank, which makes it inconvenient to reduce the dependence on additional cooling water supply by collecting external rainwater. Summary of the invention

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

[0006] In order to solve the above problems in the prior art, one or more embodiments of the present invention provide a heat-insulating and energy-saving decorative curtain wall, including a frame, inner glass and outer glass. A square inner cavity is defined in the frame. The inner glass and the outer glass are arranged relative to each other to form an interlayer, and the sides of the inner glass and the outer glass are supported by the inner edge of the frame. The upper and lower ends of the frame respectively have channels connecting the outside and the interlayer. A slider that can slide along the thickness direction of the curtain wall is installed on the upper part of the frame, and the upper end of the outer glass is rotatably connected to the slider through a rotating shaft. The lower end of the frame has a support block, and the support block has an arc-shaped support surface. The center line of the support surface is parallel to the width direction of the curtain wall, and the lower end of the outer glass is supported by the support surface. The rotating shaft includes a shell with a hollow outer periphery and a water-absorbing core embedded in the shell, a water-absorbing cavity is provided on the frame, a water-permeable hole connected to the water-absorbing cavity is provided on the support surface, and a water-absorbing block is provided in the water-absorbing cavity. Water-absorbing strips connecting the water-absorbing core and the water-absorbing block are provided on both sides of the outer glass along the width direction.

[0007] The decorative curtain wall has a water absorption state and an evaporation state. In the water absorption state, the slider drives the upper end of the outer glass and the rotating shaft to slide outward along the thickness direction of the curtain wall until the rotating shaft protrudes from the frame, and the upper end of the outer glass tilts toward the outside. In the evaporation state, the slider and the outer glass slide inward along the thickness direction of the curtain wall, the rotating shaft is embedded in the frame, and the outer glass is arranged vertically.

[0008] Furthermore, it also includes a plurality of photovoltaic panels arranged on the interlayer and rotating in sequence along the width direction of the curtain wall, the slider is fixed to the crossbeam, the lower end of the photovoltaic panel is suspended in the air, and the upper end is installed on the crossbeam, the rotation axis on the photovoltaic panel is vertically arranged in the middle of the width direction, and the distance between adjacent rotation axes is smaller than the distance between the side of the photovoltaic panel and its own center along the width direction;

[0009] The upper end of the outer glass has a first position and a second position in the water absorbing state. In the first position, the vertical projections of the rotating shaft and the frame are in contact; in the second position, the vertical projections of the rotating shaft and the frame do 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, and the two photovoltaic panels of each photovoltaic pair rotate around the rotating shaft respectively to combine into a V-shaped structure abutting the outer glass, with the opening of the V-shaped structure facing the inner glass, and a guide groove is formed on the inner side of the V-shaped structure.

[0010] Furthermore, the curtain wall also has a power generation state and a light transmission state in which the outer glass is arranged vertically. In the power generation state, the photovoltaic panels are perpendicular to the thickness direction of the curtain wall. In the light transmission state, the photovoltaic panels are parallel to the thickness direction of the curtain wall, and light transmission spaces are formed between adjacent photovoltaic panels.

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

[0012] Furthermore, there are two sliders, which are arranged at both ends of the curtain wall along its width direction. A beam is fixed on one side of the slider close to the inner glass, and a rotating shaft is installed on the other side.

[0013] Furthermore, the upper and lower ends of the frame also have passages connecting the interior of the room and the interlayer, and the passages and channels can be opened and closed independently.

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

[0015] Furthermore, it also includes a screw and an elastic reset member, 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 the outer glass, and the elastic reset member is used to provide a pulling force for the outer glass to move into the room to an evaporation state.

[0016] Advantages of the above one or more technical solutions:

[0017] In this solution, in the water absorption state, the outer glass can move along the thickness direction of the curtain wall with the slider, so that the rotating shaft and the water absorption core at the upper end of the outer glass are exposed to the outside of the curtain wall to facilitate the absorption of rainwater from the outside; and at this time, the lower end of the outer glass only changes its own posture by rotating, and it is still supported by the arc surface at the lower end of the frame and will not protrude from the entire curtain wall. This makes the outer glass face the inner glass in an inclined downward and inward manner, which can realize the stable support of the outer glass while using the inclination of the outer glass to cooperate with the water absorption strip to guide the rainwater from the water absorption core to the water absorption block.

[0018] In this solution, in the evaporation state, the slider can drive the outer glass to slide in the reverse direction, and then reset the outer glass and the rotating shaft, and the entire outer glass is vertically arranged inside the frame. That is, in this setting method, the outer glass, the rotating shaft, etc. are covered inside the frame to prevent the upper end of the interlayer from directly contacting the external environment and avoid accumulating more dust and other dirt inside the interlayer.

[0035] Such as Figures 1 - 11As shown in the figure, a heat-insulating and energy-saving decorative curtain wall provided in this embodiment includes a frame 4, an inner glass 1, and an outer glass 6. A square inner cavity is defined within the frame 4. The inner glass 1 and the outer glass 6 are arranged opposite to each other to form an interlayer 2, and the sides of the two are supported by the inner edges of the frame 4. There are channels at the upper and lower ends of the frame 4 that communicate the outside with the interlayer 2. A slider 5 that can slide in the thickness direction of the curtain wall is installed at the upper part of the frame 4. The upper end of the outer glass 6 is rotatably connected to the slider 5 through a rotating shaft 11. The lowermost end of the frame 4 has a support block with an arc-shaped support surface, and the center line of the support surface is parallel to the width direction of the curtain wall. The lower end of the outer glass 6 is supported by the support surface. The rotating shaft 11 includes a housing with a hollow outer periphery and a water-absorbing core (not shown in the figure) embedded in the housing. There is a water-absorbing cavity 20 on the frame 4, and there are water-permeable holes (not shown in the figure) on the inner bottom surface of the frame and the support surface that communicate with the water-absorbing cavity 20. There is a water-absorbing block 21 in the water-absorbing cavity 20, and water-absorbing strips 18 that connect the water-absorbing core and the water-absorbing block 21 are provided on both sides of the outer glass 6 in the width direction.

[0036] Specifically, the frame 4 here is square, which includes a top frame arranged horizontally and a bottom frame 41. Vertical frames are installed between the top frame and the bottom frame 41. The cross-sections of the top frame, the bottom frame 41, and the vertical frames here are approximately square. Each of the top frame, the bottom frame 41, and the vertical frames of the frame 4 can be formed by an integral manufacturing method, or can be manufactured separately and then fixed by angle irons 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 in pairs. Among them, the first direction is arranged horizontally and serves as the width direction of the curtain wall, and the second direction is arranged approximately vertically to serve as the height direction of the curtain wall.

[0038] Specifically, the inner glass 1 and the outer glass 6 are respectively arranged on the inner and outer sides of the curtain wall in its own thickness direction. The inner glass 1 faces the interior of the building, and the outer glass 6 faces the exterior of the building. When the curtain wall is in the evaporation working state, the outer glass 6 is approximately vertical, and at this time, the space of the interlayer 2 is approximately square. The inner glass 1 and the outer glass 6 each have four sides. Taking the inner glass 1 as an example, the side at its top is fixed to the top frame, and the side at its bottom is fixed to the bottom frame 41 to achieve support. More specifically, a sheath 61 is fixed around the outer glass 6, and the sheath 61 is used to connect the rotating shaft 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. As a result, the outside air enters the interlayer 2 through the air inlet channel, forming an upward heat dissipation air flow in the interlayer 2. This air flow can carry away the heat accumulated in the interlayer 2 in hot summer, preventing excessive heat accumulation in the structure of the double-glass curtain wall and further avoiding the conduction of this part of the heat to the indoor environment by means of thermal radiation. In cold winter, by closing the air outlet channel and the air inlet channel, the interlayer 2 can be completely isolated from the external environment, thereby reducing the probability of indoor heat being dissipated to the outside through the curtain wall. That is, the glass curtain wall in this embodiment is a breathing curtain wall structure, which is convenient for achieving the effect of heat preservation and energy saving.

[0040] Specifically, in this embodiment, there is a slider 5 on each side of the frame 4 along its first direction. A chute is arranged on the frame 4 in the thickness direction of the curtain wall. Here, the chute penetrates the outer surface of the frame 4, and the slider 5 is inserted into the chute. The two sliders 5 are respectively arranged on both sides of the upper end of the outer glass 6 along the first direction, and the two sliders 5 are respectively rotatably connected to the upper end of the outer glass 6 through the above-mentioned rotating shaft 11. Specifically, after the rotating shaft 11 passes through the support frame 62 at the upper end of the outer glass 6, both ends of the rotating shaft 11 are rotatably connected to the two sliders 5. Preferably, the cross-sections of the chute and the slider 5 here can be T-shaped or dovetail-shaped to prevent the slider 5 from falling off the chute vertically.

[0041] In this embodiment, the support block is an elastic block made of materials such as silica gel or rubber. In the contact with the elastic material of the support block, it is convenient to achieve the close contact between the lower part of the outer glass 6 and the support block, thereby avoiding the connection between the interlayer 2 and the outdoor environment through the gap between the frame 4 and the lower part of the outer glass 6 under unnecessary circumstances. Specifically, the upper surface of the support block forms the arc-shaped support surface. When the center line of the support surface is parallel to the current width direction, during the process of the upper end of the outer glass 6 sliding along the thickness direction of the curtain wall with the slider 5 and the outer glass 6 rotating around the rotating shaft 11: the support surface can always support the outer glass 6, avoiding the situation that the lower end of the outer glass 6 is suspended, causing the rotating shaft 11 and the slider 5 to bear a large gravity of the outer glass 6.

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

[0043] In the case of using a combination of a water-absorbing core, a water-absorbing strip 18, and a water-absorbing block 21, the three can evenly disperse the rainwater absorbed at the rotating shaft 11 and store it in the water-absorbing core, the water-absorbing strip 18, and the water-absorbing block 21, preventing the rainwater from splashing everywhere in the interlayer 2 and avoiding the influence of the rainwater splashing in the interlayer 2 on the perspective function of the curtain wall.

[0044] The decorative curtain wall has a water-absorbing state and an evaporation state. In the water-absorbing 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 from the frame 4, and the upper end of the outer glass 6 inclines outward. In the evaporation state, the slider 5 and the outer glass 6 slide inward along the thickness direction of the curtain wall, and the rotating shaft 11 is embedded in the frame 4, and the outer glass 6 is vertically arranged.

[0045] During use, if it is a hot summer environment and it is rainy outdoors, in order to collect the outdoor rainwater for subsequent use of this part of the rainwater to achieve the evaporation heat dissipation of the interlayer 2, the upper end of the slider 5 slides on the outer side of the curtain wall. At this time, the upper end of the outer glass 6 and the rotating shaft 11 slide outward synchronously with the slider 5, so that the rotating shaft 11 above the outer glass 6 is exposed to the outside. It can absorb some rainwater from the hollow holes to the water-absorbing core during the process of being washed by the rainwater, and finally drain the rainwater to the inside of the interlayer 2.

[0046] When enough rainwater is accumulated in the interlayer 2, the slider 5 drives the rotating shaft 11 and the upper end of the outer glass 6 to move toward the indoor direction to reset the outer glass 6. At this time, the upper end of the outer glass 6, the rotating shaft 11, etc. are completely covered inside the frame 4 and will not be affected by the external rainwater. When the rainfall stops, open the air intake channel and the air outlet channel on the frame 4. During the process of the air flow flowing through the interlayer 2, it will gradually take away the water accumulated in the water-absorbing block 21 in the interlayer 2, and the evaporation of the water vapor will achieve the cooling of the interlayer 2 and even the entire curtain wall.

[0047] It can be known that when the outdoor precipitation is large, the rotating shaft 11 at the upper end of the outer glass 6 can absorb enough rainwater into the interlayer 2 and complete the storage of the rainwater. However, when the external precipitation is small, the short-term and small amount of rainwater is not enough to accumulate enough rainwater in the interlayer 2. In order to accumulate enough rainwater in the interlayer 2 in a light rain environment: in this embodiment, it further includes a plurality of photovoltaic panels 7 rotatably arranged in sequence along the width direction of the curtain wall in the interlayer. The slider is fixed to the cross beam. The lower end of the photovoltaic panel is suspended, and the upper end is installed on the cross beam. The distance between adjacent rotating shafts is less than the distance between the side of the photovoltaic panel along the width direction and its center.

[0048] The upper end of the outer glass has a first position and a second position in the water-absorbing state. In the first position, the rotating shaft contacts the vertical projection of the frame. In the second position, the vertical projections of the rotating shaft and the frame do 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, and the two photovoltaic panels 7 of each photovoltaic pair rotate around the rotating shaft respectively to form a V-shaped structure abutting against the outer glass. The opening of the V-shaped structure faces the inner glass, and a diversion groove 73 is formed inside the V-shaped structure.

[0049] It is known that the distance that the slider 5 needs to move for the upper end of the outer glass 6 to move to the first position is L1, and the distance that the slider 5 needs to move for the upper end of the outer glass 6 to move to the second position is L2, and 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 has been formed between the rotating shaft 11 and the frame 4, and this water inlet 51 can already directly introduce water into the interlayer 2.

[0050] The above-mentioned rotation of the photovoltaic panels 7 forms a plurality of diversion grooves 73 in the interlayer 2. The diversion grooves 73 can smoothly guide the rainwater flowing in from the water inlet 51 to the bottom of the interlayer 2, avoiding the rainwater splashing everywhere, and reducing the probability that the rainwater splashes everywhere in the interlayer 2 onto the inner glass and the outer glass and affects the light transmission.

[0051] In some embodiments, in order to make the side formed by adjacent photovoltaic panels 7 abut against the inner side surface of the outer glass 6, and further make the diversion groove 73 and the rainwater in the diversion groove 73 flow obliquely downward in a direction parallel to the outer glass 6, the upper end of the rotating shaft 8 of the photovoltaic panel 7 rotates around the horizontal rotating shaft 10, so that the rotating shaft 8 is parallel to the outer glass 6.

[0052] In order to drive the rotation of the rotating shaft 8, a linkage shaft is provided through the lower end of the rotating shaft 8. The linkage shaft is parallel to the axis of the rotating shaft 10 and is rotatably installed at 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 form a deformable parallelogram structure. It is known that on the basis of the above-mentioned formation of the parallelogram structure, the rotation of the outer glass 6 will cause the rotation of the rotating shaft 8 in a linkage manner, so that the two always remain parallel. Specifically, the rotation of the photovoltaic panel 7 relative to the rotating shaft 8 here can refer to the structure of the existing shutter. Adjacent photovoltaic panels 7 are connected by multiple wires, and the tightening or loosening of the wires can drive the above-mentioned photovoltaic panels 7 to adjust the orientation. The specific connection method of the wires here will not be elaborated, and it can be set by those skilled in the art themselves.

[0053] In addition, in the case of not using the linkage rod 22, a wire or a micro-motor drive method can also be used to make the rotating shaft 8 rotate around the horizontal rotating shaft 11 until the rotating shaft 8 is parallel to the inclined outer glass 8, which will not be elaborated here.

[0054] In this embodiment, there are a plurality of water baffle plates (not shown in the figure) arranged staggeredly along the width direction of the curtain wall on the cross beam 19. The water baffle plates are used to fill the gaps between adjacent photovoltaic pairs to prevent rainwater flowing in from the water inlet from directly flowing into the interlayer through the gaps between adjacent photovoltaic pairs without being guided by the diversion groove 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 panel 7 is perpendicular to the thickness direction of the curtain wall. In the light transmission state, the photovoltaic panel 7 is parallel to the thickness direction of the curtain wall, and a light transmission space is formed between adjacent photovoltaic panels 7.

[0056] Specifically, when there is sufficient sunlight during the day, the photovoltaic panel 7 is perpendicular to the thickness direction of the curtain wall, which can increase the area of the photovoltaic panel 7 directly irradiated by the sun, so as to improve the power generation efficiency of the photovoltaic panel 7. In the light transmission state, although the photovoltaic panel 7 can still receive external light, its power generation efficiency will decrease without direct sunlight. However, in the light transmission state, more light will pass through the gaps between adjacent photovoltaic panels 7 and enter the indoor environment.

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

[0058] Specifically, when the flat gasket 72 and the U-shaped gasket 71 are used in cooperation, the overlapping positions of two paired photovoltaic panels 7 can be in close contact, preventing rainwater from leaking from this position. More specifically, the U-shaped gasket 71 and the flat gasket 72 here can be made of elastic materials such as rubber or silicon.

[0059] In this embodiment, one side of the slider 5 close to the inner glass 1 is fixed to the cross beam 19, and the other side is installed with a rotating shaft 11. Specifically, there is a large gap between the cross beam 19 and the rotating shaft 11, and this gap facilitates the formation of the above-mentioned water inlet 51 between the rotating shaft 11 and the frame 4.

[0060] In this embodiment, there are also passages connecting the indoor and the interlayer 2 at the upper and lower ends of the frame 4, and both the passages and the channels can be independently opened and closed.

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

[0062] In some embodiments, micro fans are respectively arranged in the air outlet passage and the above-mentioned air outlet channel 9. The micro fans are used to increase the flow rate of the air flow in the interlayer 2, so as to better achieve the cooling of the interlayer 2.

[0063] Specifically, a vertically upward extending pipe 12 is provided on the bottom frame 401. The upper end of the extending pipe 12 is higher than the bottom frame 401, and the lower end of the extending pipe 12 is respectively communicated with the air inlet passage and the air inlet path. When the extending pipe 12 is higher than the bottom frame 401, it can prevent the rainwater accumulated in the interlayer 2 from flowing back from the air inlet path or the air inlet passage.

[0064] In this embodiment, the water absorption core, the water absorption block 21 and the water absorption strip 18 are all made of sponge material. It can be known that when the sponge material is used, it is convenient for the diffusion along the internal voids of the sponge, and then it can be quickly stored inside the interlayer 2 of the curtain wall. In some other embodiments, the sponge can be replaced with cotton or other water-absorbing polymers, which can be set by those skilled in the art themselves.

[0065] In this embodiment, the rotating shaft 11 and the supporting surface are respectively and uniformly provided with hollow holes. As a specific structural form, the hollow holes can be square holes or circular holes, and the hollow holes of this shape are convenient for manufacturing. The hollow holes here can be other shapes such as triangles or rhombuses, which can be set by those skilled in the art themselves.

[0066] In this embodiment, it further includes a screw rod 14 and an elastic resetting member. The axis of the screw rod 14 is parallel to the thickness direction of the curtain wall. One end of the screw rod 14 passes through the inner glass, and the other end abuts against the outer glass 6. The elastic resetting member is used to provide a pulling force for the outer glass 6 to move towards the indoor to the evaporation state.

[0067] Specifically, a nut seat is fixed on the frame 4, and the screw hole on the nut seat penetrates through the inner glass 1. The screw rod 14 is arranged inside the screw hole. A runner 16 and a handle are installed at one end of the screw rod 14 located indoors, and the other end of the screw rod 14 abuts against the sheath 61 of the outer glass 6. The elastic resetting member adopts a spring 15. One end of the spring 15 is fixed on the inner side surface of the outer glass 6, and the other end of the spring 15 is fixed on the inner side surface of the frame 4. More specifically, the spring 15 and the screw rod 14 here are both installed at the upper end of the curtain wall.

[0068] It can be known that when the screw rod 14 moves outwards to push the slider 5 away from the interlayer, since the lower end of the outer glass 6 is limited by the arc-shaped supporting surface, the lower end of the outer glass 6 will not move outwards. Therefore, when the upper end of the outer glass 6 moves outwards, it will cause itself to rotate relative to the slider around the rotating shaft 11, and then the upper end of the outer glass 6 will tilt outwards.

[0069] In some other embodiments, when it is not convenient to arrange the runner inside the indoor structure on the inner side of the curtain wall, the runner 16 and the handle may not be installed at the screw rod 14, and the screw rod 14 can be driven to rotate by a micro motor and the corresponding transmission structure.

[0070] In this embodiment, a plurality of brackets 3 are fixed on the side of the frame close to the interior. The brackets 3 here are used to realize the connection between the curtain wall and the fixed support structure of the building exterior wall.
