Description

Technical Field

[0001] This application relates to the field of construction, and more particularly to a photovoltaic module operable window and a photovoltaic glass curtain wall. Background Technology

[0002] In order to make effective use of solar energy resources, the building exterior is designed as a photovoltaic glass curtain wall to maximize the conversion of solar energy resources.

[0003] Photovoltaic curtain walls generate or absorb heat during operation, causing the internal temperature to rise. Because the curtain wall is close to the building wall, if heat dissipation is ineffective, the photovoltaic modules are at risk of cracking. Simultaneously, the indoor temperature will also rise, and locally excessively high temperatures can pose a fire hazard. Glass curtain walls are typically designed with operable panels, which can be manually opened to achieve indoor-outdoor ventilation.

[0004] However, the aforementioned glass curtain wall opening method cannot be effectively applied to photovoltaic curtain walls. Manually opening the curtain wall prevents timely ventilation and heat dissipation when the temperature rises, posing a safety hazard. Summary of the Invention

Detailed Implementation

[0047] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0048] Reference Figure 1-5As shown in the figure, an embodiment of the present invention discloses a photovoltaic module opening fan for mounting on a crossbeam of a building. The crossbeam includes an upper crossbeam 45 and a lower crossbeam 64. The photovoltaic module opening fan includes an upper sub-frame 10 of the photovoltaic module, a lower sub-frame 20 of the photovoltaic module, and a photovoltaic module. The upper sub-frame of the photovoltaic module includes a connecting part and a first mounting part fixedly connected to one side of the connecting part. The connecting part is movably connected to the upper crossbeam and is used to rotate around the upper crossbeam 45. The first mounting part is used to fix the upper side of the photovoltaic module 40. The lower sub-frame of the photovoltaic module includes a thermosensitive telescopic part and a second mounting part disposed on one side of the thermosensitive telescopic part. The other side of the thermosensitive telescopic part is fixedly connected to the lower crossbeam 64. The second mounting part is used to fix the lower side of the photovoltaic module 40. When the temperature rises, the thermosensitive telescopic part undergoes an expansion deformation, so that under the rotational cooperation of the connecting part, the second mounting part drives the lower side of the photovoltaic module to move away from the crossbeam, thereby opening the photovoltaic module opening fan.

[0049] Specifically, the upper sub-frame 10 and the lower sub-frame 20 of the photovoltaic module are the frames for fixing the photovoltaic module. The upper sub-frame 10 is used to fix the upper side of the photovoltaic module, and the lower sub-frame 20 is used to fix the lower side of the photovoltaic module. This allows the photovoltaic module, fixed inside the sub-frame, to move synchronously as the upper and lower sub-frames of the photovoltaic module move.

[0050] For photovoltaic (PV) modules to be installed on the wall surface of a building, load-bearing beams, supporting columns, and other structural frames must first be fixedly installed on the exterior wall surface before the PV modules are installed on the beams. (Refer to...) Figure 3 The upper sub-frame 10 of the photovoltaic module includes a connecting part, which is the part that connects the upper sub-frame 10 of the photovoltaic module to the upper horizontal beam 45 of the building exterior. The connecting part and the upper horizontal beam 45 can be movably connected, so that the photovoltaic module can be opened. The first mounting part is the part that fixes the upper side of the photovoltaic module 40. A flexible gasket can be set at the position where the upper side of the photovoltaic module contacts the first mounting part to avoid rigid contact between the photovoltaic module 40 and the first mounting part. At the same time, the connection between the upper side of the photovoltaic module and the first mounting part is bonded by structural adhesive 44.

[0051] The lower sub-frame of the photovoltaic module includes a thermosensitive expansion joint, which is a component that expands and contracts upon sensing temperature. The thermosensitive element for sensing temperature can be a thermosensitive spring. The second mounting part is for fixing the lower side of the photovoltaic module 40. A flexible gasket can be provided at the contact point between the lower side of the photovoltaic module and the second mounting part to avoid rigid contact between the photovoltaic module 40 and the second mounting part. Simultaneously, the connection between the lower side of the photovoltaic module and the second mounting part is secured by structural adhesive 44. The second mounting part also provides support for the photovoltaic module. Combined with the adhesive effect of the structural adhesive between the upper and lower sides of the photovoltaic module and the mounting part, the photovoltaic module is fixed within the upper and lower sub-frames. Alternatively, the photovoltaic module can be fixed to the upper and lower sub-frames by a snap-fit ​​mechanism; this embodiment of the invention is not limited to this method. (Reference) Figure 4 When the air temperature near the thermistor decreases, it enters a normal contraction state due to its physical properties, and the photovoltaic module's opening fan remains sealed. (Refer to...) Figure 5 When the air temperature near the thermistor rises to a certain limit, the thermistor, due to its physical properties, is in a stretched state. The photovoltaic module, subjected to the force released by the deformation of the thermistor, opens its lower end as the connecting parts rotate, thus achieving ventilation. The thermistor automatically senses temperature and expands or contracts, causing the photovoltaic module's opening doors to open and close automatically, thus automatically realizing the ventilation and heat dissipation function of the photovoltaic curtain wall.

[0052] Optionally, refer to Figure 2 , Figure 4 The thermal expansion joint includes: a first frame plate 22, a second frame plate 23, and a thermal element 24; one side of the first frame plate 22 is provided with a first slot 221, and one side of the second frame plate 23 is provided with a second slot 222; the first slot 221 and the second slot 222 are opposite to each other; one end of the thermal element 24 is fixedly disposed in the first slot 221, and the other end of the thermal element 24 is fixedly disposed in the second slot 222; the first frame plate 22 is fixedly connected to the lower crossbeam 64.

[0053] Specifically, the thermistor 24 can be a thermal spring or other components that can deform and have a certain rigidity, so that the thermistor will not sway due to external forces when encountering severe weather such as strong winds and heavy rain. One end of the thermistor 24 is fixed in the first slot 221, and the first frame plate 22 can be fixedly connected to the lower crossbeam through the glass sub-frame pressure block 48. That is, one end of the thermistor 24 is fixedly set at the lower crossbeam, and the other end of the thermistor 24 is set in the second slot 222. When the thermistor expands due to heat, the thermistor in the second slot extends, generating a force away from the crossbeam, which drives the second frame plate 23 and the second mounting part fixedly connected to the second frame plate 23 to move away from the crossbeam at the same time, so that the lower end of the photovoltaic module opening fan opens.

[0054] Optionally, refer to Figure 2 , Figure 4 A sealing strip 21 is provided in the first groove 221 and the second groove 222.

[0055] Specifically, sealing strips 21 are provided in the first slot 221 and the second slot 222. The sealing strips 21 can fill the entire first slot 221 and the second slot 222. When the photovoltaic module is in the open and closed state, the sealing strips located in the first slot 221 and the second slot 222 squeeze each other, sealing the lower sub-frame of the photovoltaic module from the outside, and preventing water vapor from entering the interior of the photovoltaic curtain wall.

[0056] Optionally, refer to Figure 2 , Figure 4 The second mounting section includes: a first support plate 28; the plane of the first support plate 28 is perpendicular to the plane of the second frame plate 23, and the first support plate is used to support the photovoltaic module.

[0057] Specifically, the second installation part is for assembling the lower side of the photovoltaic module. The first support plate 28 can bear the weight of the photovoltaic module. The position where the lower side of the photovoltaic module contacts the first support plate 28 also needs to be sealed with sealant 46 to prevent moisture from entering the photovoltaic curtain wall from the position where the lower side of the photovoltaic module contacts the first support plate 28 and affecting the performance of the photovoltaic curtain wall. A flexible gasket is also provided between the contact surface of the photovoltaic module and the first support plate 28 to prevent the photovoltaic module from making rigid contact with the first support plate.

[0058] Optionally, refer to Figure 2 , Figure 4 The second mounting part also includes: a first frame, mounting brackets 18 and adhesive strip grooves 29; the first frame is connected to the second frame plate 23 and is used to set the mounting brackets 18; a first support plate 28 is connected to one end of the first frame, and an adhesive strip groove 29 is provided on the side of the first support plate 28 facing the ground and away from the first frame, the adhesive strip groove being used to assemble the waterproof adhesive strip.

[0059] Specifically, the two ends of the first connecting plate 26 are connected to the other side of the second frame plate 23 and the third frame plate 25, respectively. The two ends of the second connecting plate 27 are connected to the other side of the second frame plate 23 and the third frame plate 25, respectively. The second frame plate 23, the third frame plate 25, the first connecting plate 26, and the second connecting plate 27 form a rectangular first frame for mounting corner brackets 18, which are used to fix the upper and lower sub-frames. One end of the first support plate 28 is connected to the other end of the second connecting plate 27, and the first support plate 28 and the second connecting plate 27 are on the same plane. The first support plate 28 is used to support the photovoltaic module. The first support plate 28 and the second connecting plate 27 can be an integrally formed structure.

[0060] Furthermore, the other end of the first support plate 28, facing the ground, is provided with a groove 29 for a waterproof strip. A drip edge can be installed within the groove 29. This drip edge can be designed to run the entire length of the strip to prevent large amounts of rainwater from entering the photovoltaic glass curtain wall. (Reference) Figure 4 Sealant 47 is also installed in the space between the photovoltaic module's opening window and the conventional transparent glass to prevent moisture from entering through the waterproof strip.

[0061] Optionally, refer to Figure 2 , 4 The lower side of the photovoltaic module 40 is bonded to the first frame by structural adhesive 44, and double-sided adhesive is provided between the structural adhesive 44 and the first support plate 28.

[0062] Specifically, a flexible gasket can be provided on the first support plate 28 to avoid rigid contact between the photovoltaic module and the first support plate 28. The lower side of the photovoltaic module and the third frame plate 25 can be connected by structural adhesive 44. The structural adhesive has high strength, peel resistance, impact resistance, and simple construction process, and can fix the photovoltaic module to the lower sub-frame of the photovoltaic module. The structural adhesive can only connect and fix a portion of the area of ​​the third frame plate 25 to the lower side of the photovoltaic module, and the remaining space can be filled with double-sided adhesive tape. The double-sided adhesive tape can be adhered to the first support plate and can be made of foam or other materials. Using double-sided adhesive tape can save the amount of structural adhesive used. The amount of structural adhesive used can be calculated according to actual use, and this embodiment of the invention is not limited here.

[0063] Optionally, refer to Figure 1 , Figure 3 The connecting part includes: an arc-shaped hook 11, the inner side of which is an arc-shaped curved surface.

[0064] Specifically, the connecting part can be movably connected via the arc-shaped hook 11. The upper crossbeam 45 can be pre-set with a support column. When the arc-shaped hook is attached to the head of the support column of the upper crossbeam, the arc shape of the head of the support column is adapted to the curvature of the inner side of the arc-shaped hook, allowing the arc-shaped hook 11 to rotate around the head of the support column within a certain range. This allows the photovoltaic module's opening fan to be opened.

[0065] Optionally, refer to Figure 1 , Figure 3 The first mounting part includes: a second frame, a first sealing plate 13, a second sealing plate 14, and a mounting bracket 18; the second frame is used to set the mounting bracket, one side of the arc-shaped hook is connected to one end of the second frame, the other end of the second frame is connected to one end of the first sealing plate, and the other end of the first sealing plate is perpendicularly connected to one end of the second sealing plate. The second frame, the first sealing plate, and the second sealing plate form a snap-fit ​​space for snapping the upper side of the photovoltaic module.

[0066] Specifically, the third connecting plate 12, the fourth connecting plate 17, the fourth frame plate 15, and the fifth frame plate 16 together form a rectangular second frame. An installation corner bracket is provided in the second frame. One side of the arc-shaped hook 11 is connected to one end of the third connecting plate 12, and the other end of the third connecting plate 12 is connected to one end of the first sealing plate 13. One end of the second sealing plate 14 is perpendicularly connected to the other end of the first sealing plate 13. The third connecting plate 12 and the first sealing plate 13 are on the same plane. The fifth frame plate 16, the first sealing plate 13, and the second sealing plate 14 form a snap-fit ​​space for snapping the upper side of the photovoltaic module 40. The third connecting plate 12, the fourth connecting plate 17, the fourth frame plate 15, and the fifth frame plate 16 can be integrally formed structures. The first sealing plate 13 and the second sealing plate 14 can also be integrally formed structures. The first mounting part as a whole can also be an integrally formed structure.

[0067] The second frame provides stable support for the photovoltaic modules. The mounting brackets 18 connect and fix the lower sub-frame of the photovoltaic module to other sub-frame structures via the frame structure. One end of the second sealing plate 14 is perpendicularly connected to the other end of the first sealing plate 13, and the other end extends downwards. The third connecting plate 12 and the fourth connecting plate 17 are opposite ends located on one side of the fifth frame plate 16, parallel to each other. The third connecting plate 12 and the first sealing plate 13 are on the same plane and can be integrally formed. The plane formed by the third connecting plate 12 and the first sealing plate 13 can prevent rainwater or moisture from entering the photovoltaic curtain wall, preventing leakage. Flexible gaskets are installed on the contact surfaces of the first sealing plate 13 and the second sealing plate 14 with the upper side surface of the photovoltaic module to prevent hard contact between the photovoltaic module and the upper sub-frame, providing cushioning, shock absorption, anti-slip, and breakage prevention. Additionally, sealant is applied at the contact points between the photovoltaic module and the upper sub-frame to prevent moisture from entering through gaps. The upper side of the photovoltaic module is fixedly connected to the fifth frame plate with structural adhesive. The amount and cross-sectional size of the structural adhesive are determined according to the actual use.

[0068] In summary, this invention discloses a photovoltaic module opening fan and a photovoltaic glass curtain wall for mounting on a building beam. The beam includes an upper beam and a lower beam. The photovoltaic module opening fan includes an upper sub-frame, a lower sub-frame, and a photovoltaic module. The upper sub-frame includes a connecting part and a first mounting part fixedly connected to one side of the connecting part. The connecting part is movably connected to the upper beam and is used to rotate around the upper beam. The first mounting part is used to fix the upper side of the photovoltaic module. The lower sub-frame includes a thermosensitive telescopic part and a second mounting part disposed on one side of the thermosensitive telescopic part. The other side of the thermosensitive telescopic part is fixedly connected to the lower beam. The second mounting part is used to fix the lower side of the photovoltaic module. The thermosensitive telescopic part is used to generate an extension deformation when the temperature rises, so that under the rotational cooperation of the connecting part, the second mounting part drives the lower side of the photovoltaic module to move away from the beam, thereby opening the photovoltaic module opening fan. The thermosensitive expansion joint automatically extends when the temperature rises, causing the photovoltaic module's opening fan to open and dissipate heat in a timely manner. When the temperature drops, the thermosensitive expansion joint retracts, and the photovoltaic module's opening fan returns to a sealed position. This allows the photovoltaic curtain wall to automatically open or close the opening fan according to temperature changes, enabling timely ventilation and heat dissipation when the internal temperature rises.

[0069] Secondly, refer to Figure 7 , 8 9, 10, Embodiments of the present invention disclose a photovoltaic glass curtain wall, comprising: a glass curtain wall and a photovoltaic curtain wall, wherein the glass curtain wall is disposed in the light-transmitting area of ​​the building, and the photovoltaic curtain wall is disposed in the non-light-transmitting area of ​​the building, and the photovoltaic curtain wall includes a photovoltaic module operable sash as described in the first aspect.

[0070] Specifically, the glass curtain wall is installed in the light-transmitting area of ​​the building, while the photovoltaic curtain wall is installed in the non-light-transmitting area of ​​the building. This allows for the effective utilization of solar energy resources without obstructing the building's lighting. The installation sequence of the photovoltaic glass curtain wall can be as follows: the building structure 50 and the embedded system 57 are reliably connected by fasteners such as screws and anchors. The system can be pre-installed in the building structure. Construction layout and installation of floor transition pieces 54 are then carried out. Next, the vertical support columns 58 are installed, the horizontal beams are installed, the support columns and horizontal beams are adjusted, the steel connection positions are fully welded, anti-corrosion measures and lightning protection are implemented for the steel components, fireproof iron sheets 51 are installed, fireproof sealing metal plates 53 are installed, fireproof rock wool 52 is laid, thermal insulation rock wool 55 is installed, photovoltaic module panels and photovoltaic junction boxes 56 are installed, pressure plates are installed, sealant is applied, and subsequent work such as glass cleaning is carried out.

[0071] Further, refer to Figure 7 When the thermistor is heated, the photovoltaic module's ventilation fan can open at a certain angle for ventilation. (Reference) Figure 8When the temperature around the thermistor decreases, the photovoltaic module's open window can return to a closed state. At this time, the photovoltaic curtain wall is in a sealed state that isolates it from the outside world. Sealing strips are installed at the connection points of the photovoltaic modules for sealing.

[0072] Optionally, refer to Figure 6 , Figure 8 , Figure 9 The glass curtain wall includes: a glass support plate; the glass support plate includes a load-bearing part and an arc-shaped baffle, the load-bearing part is used to support conventional transparent glass; the curved surface of the arc-shaped baffle fits with the outer surface of the arc-shaped hook.

[0073] Specifically, a photovoltaic glass curtain wall can be composed of photovoltaic modules and conventional transparent glass. When conventional transparent glass is above the operable sash of the photovoltaic module, the upper sub-frame of the operable sash of the photovoltaic module can cooperate with the sub-frame of the conventional transparent glass. Since the shear strength of the structural adhesive is weak and cannot bear the load of the conventional transparent glass for a long time, a support plate is also required at the lower end of the conventional transparent glass 41, which is fixed to the glass sub-frame 49 by the structural adhesive, to support the conventional transparent glass. By connecting and fixing the glass support plate 30 to the glass sub-frame, the load of the conventional transparent glass is transferred to the glass support plate, thereby avoiding the structural adhesive from bearing shear force and breaking. There can be multiple glass support plates, which can be set according to actual needs to increase the safety of load bearing.

[0074] Furthermore, the sub-frame 10 of the photovoltaic module and the glass support plate 30 can be connected by an arc-shaped baffle 31. The arc-shaped baffle 31 is located on the outside of the arc-shaped hook, and the curvature of the groove of the arc-shaped baffle 31 is adapted to the curvature of the outer side of the arc-shaped hook. This allows the arc-shaped baffle 31 to prevent the arc-shaped hook from falling upwards and forwards when it rotates around the arc surface of the head of the support column, thus preventing the photovoltaic module from falling off. This limits the rotation range of the arc-shaped hook to a safe range. The opening effect of the photovoltaic module's opening fan is achieved through the connection between the arc-shaped baffle, the arc-shaped hook, and the head of the support column.

[0075] Optionally, refer to Figure 3 , Figure 6 The supporting part includes: a second support plate 33 and a third support plate 36; the second support plate 33 is provided with a hook 34 on the side facing the conventional light-transmitting glass 41 for hanging the glass support plate 30 on the sub-frame 42 of the conventional light-transmitting glass 41; a limit plate 35 is provided at one end of the second support plate 33; one end of the arc-shaped baffle 31 is connected to the other end of the second support plate 33; one end of the third support plate 36 is perpendicularly connected to the second support plate 33; the other end of the third support plate 36 is provided with a rubber strip groove 32 on the side facing the ground for assembling a waterproof rubber strip.

[0076] Specifically, the glass support plate 30 is used to support the conventional translucent glass 41. The glass support plate 30 can be hung on the sub-frame 42 of the conventional translucent glass 41 via hooks 34. The sub-frame 42 of the conventional translucent glass 41 can be pre-set with a structure to accommodate the hooks of the glass support plate 30, thereby reducing the need for nailing and improving the ease of installation. One end of the second support plate 33 is provided with a limiting plate 35. The limiting plate 35 contacts the glass sub-frame, restricting the range of motion of the hooks, making the connection more secure and preventing the glass support plate from shaking, which could affect the safety of the glass curtain wall.

[0077] Furthermore, the other end of the third support plate 36 facing the ground is provided with a strip groove 32. A drip edge strip can be installed in the strip groove 32. The drip edge strip can be adapted to the full length design of conventional light-transmitting glass to block rainwater from entering the photovoltaic glass curtain wall.

[0078] Optionally, refer to Figure 3 The upper crossbeam 45, which is movably connected to the sub-frame of the photovoltaic module, is equipped with a support column. The head of the support column is an arc shape that fits the inner side of the arc hook, and the arc hook is attached to the head of the support column.

[0079] Specifically, since the connection part of the photovoltaic module opening fan needs to be movable, the upper crossbeam 45 can be pre-set with a support column. The arc shape of the head of the support column is adapted to the arc of the inner side of the arc hook, so that when the arc hook is hooked on the head of the support column of the upper crossbeam, it can rotate around the head of the support column within a certain range, so that the photovoltaic module opening fan can be opened.

[0080] Optionally, refer to Figure 10 The photovoltaic curtain wall is formed by alternating arrangements of one or more photovoltaic module opening panels 63 and one or more photovoltaic module fixed panels 61, wherein the photovoltaic module fixed panels are photovoltaic modules fixedly installed on the crossbeam.

[0081] refer to Figure 10 The photovoltaic curtain wall and the glass curtain wall can be set up alternately. The photovoltaic curtain wall is formed by alternating arrangement of one or more photovoltaic module operable windows 63 and one or more photovoltaic module fixed windows 61. The alternation can be that one photovoltaic module operable window and one photovoltaic module fixed window are arranged alternately, or multiple photovoltaic module operable windows and one photovoltaic module fixed window are arranged alternately, or multiple photovoltaic module operable windows and multiple photovoltaic module fixed windows are arranged alternately. The specific arrangement can be set according to actual needs, and the embodiments of the present invention are not limited here.

[0082] Optionally, refer to Figure 10The glass curtain wall is formed by alternating arrangements of one or more conventional light-transmitting operable glass panels 62 and one or more conventional light-transmitting fixed glass panels 41. The conventional light-transmitting operable glass panels are conventional light-transmitting glass panels that are movably installed on the crossbeam, and the conventional light-transmitting fixed glass panels are conventional light-transmitting glass panels that are fixedly installed on the crossbeam.

[0083] refer to Figure 10 Photovoltaic curtain walls and glass curtain walls can be installed alternately. A conventional light-transmitting glass curtain wall is formed by alternating one or more conventional light-transmitting operable glass panels and one or more conventional light-transmitting fixed glass panels. The alternation can be arranged by alternating one conventional light-transmitting glass panel with one conventional light-transmitting fixed glass panel, or by alternating multiple conventional light-transmitting operable glass panels with one conventional light-transmitting fixed glass panel, or by alternating multiple conventional light-transmitting operable glass panels with multiple conventional light-transmitting fixed glass panels. The specific arrangement can be set according to actual needs, and the embodiments of the present invention are not limited here.

[0084] Furthermore, a photovoltaic module opening fan 63 can be set above the non-openable conventional transparent glass fixed fan 41, and a photovoltaic module fixed fan 61 can be set above the openable conventional transparent glass opening fan 62, in order to reduce the impact on adjacent conventional transparent glass or photovoltaic modules when the opening fan is opened or closed. Figure 10 The arrangement of these elements forms a photovoltaic glass curtain wall.

[0085] In summary, this invention discloses a photovoltaic glass curtain wall for mounting on a building's crossbeams. The crossbeams include an upper crossbeam and a lower crossbeam. The photovoltaic module opening panel includes an upper sub-frame, a lower sub-frame, and a photovoltaic module. The upper sub-frame includes a connecting portion and a first mounting portion fixedly connected to one side of the connecting portion. The connecting portion is movably connected to the upper crossbeam and is used to rotate around the upper crossbeam. The first mounting portion is used to fix the upper side of the photovoltaic module. The lower sub-frame includes a thermosensitive telescopic portion and a second mounting portion disposed on one side of the thermosensitive telescopic portion. The other side of the thermosensitive telescopic portion is fixedly connected to the lower crossbeam. The second mounting portion is used to fix the lower side of the photovoltaic module. The thermosensitive telescopic portion is used to generate an extension deformation when the temperature rises, so that under the rotational cooperation of the connecting portion, the second mounting portion drives the lower side of the photovoltaic module to move away from the crossbeam, causing the photovoltaic module opening panel to open. The thermosensitive expansion joint automatically extends when the temperature rises, causing the photovoltaic module's opening fan to open and dissipate heat in a timely manner. When the temperature drops, the thermosensitive expansion joint retracts, and the photovoltaic module's opening fan returns to a sealed position. This allows the photovoltaic curtain wall to automatically open or close the opening fan according to temperature changes, enabling timely ventilation and heat dissipation when the internal temperature rises.
