[0002] Photovoltaic curtain wall is a new type of building exterior wall enclosure structure that combines solar photovoltaic power generation technology with building curtain walls. Photovoltaic curtain wall mainly converts solar energy into electrical energy through photovoltaic modules integrated in the curtain wall material, and then feeds it into the power grid or uses it inside the building, reducing energy consumption and electricity bills. It uses solar power to generate electricity, reduces dependence on traditional energy, reduces carbon emissions, and helps achieve green and sustainable development of buildings.

DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0035] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Embodiment 1: This embodiment provides a photovoltaic module, such as Figure 1 As shown, it includes a longitudinal support column 1, and transverse support columns 4 are arranged on both sides of the longitudinal support column 1. There are multiple longitudinal support columns 1 and multiple transverse support columns 4. The multiple longitudinal support columns 1 and the multiple transverse support columns 4 are crisscrossed to form a grid structure, and the photovoltaic panels 2 are installed in the grid.

[0039] like Figures 2 to 4 As shown, the photovoltaic panel 2 includes a photovoltaic cover plate 21, a power generation component, a bimetallic coil spring 24, an adjustment shaft 25, a focusing mirror 26, a slide plate 27, a combination sheet 28 and a mesh 210. Both ends of the adjustment shaft 25 are rotatably connected to the photovoltaic cover plate 21 through a rotating shaft. One end of the bimetallic coil spring 24 is fixedly installed inside the photovoltaic cover plate 21. A focusing mirror 26 is provided in the middle of the adjustment shaft 25. The focusing mirror 26 adopts an arc surface structure. The arc center line of the focusing mirror 26 is located on the power generation component. The bimetallic coil spring 24 includes a ferritic stainless steel sheet and a nickel-iron alloy sheet. The ferritic stainless steel sheet and the nickel-iron alloy sheet are riveted to each other. The rotating shaft at the end of the adjustment shaft 25 passes through the center of the bimetallic coil spring 24 and supports the adjustment shaft 25 through the rotating shaft. A bearing is fixedly installed at the end of the rotating shaft of the adjustment shaft 25 so that the deformation of the bimetallic coil spring 24 drives the adjustment shaft 25 to rotate.

[0040] like Figure 2 and Figure 3 As shown, the power generation component includes a photovoltaic cell 22 and a transparent sealing glass 23. The photovoltaic sealing plate 21 and the transparent sealing glass 23 form a closed box-like structure. The photovoltaic cell 22 is fixedly installed inside the photovoltaic sealing plate 21. There is a distance between the photovoltaic sealing plate 21 and the photovoltaic cell 22. The arc center of the focusing mirror 26 is located on the photovoltaic cell 22.

[0041] The ferritic stainless steel sheet and the nickel-iron alloy sheet that constitute the bimetallic coil spring 24 have different thermal stresses, so that the bimetallic coil spring 24 is deformed when heated, and the deformation of the bimetallic coil spring 24 is used to drive the adjustment shaft 25 to rotate, so that the focusing mirror 26 is irradiated on the photovoltaic cell 22. When the temperature is low, the adjustment shaft 25 is rotated by the deformation of the bimetallic coil spring 24, so that the focusing mirror 26 reflects light onto the photovoltaic cell 22, and the focusing mirror 26 has a focusing effect, which increases the heat received by the photovoltaic cell 22, thereby improving the power generation effect.

[0042] like Figure 4 As shown, the slide plate 27 slides left and right on the inner wall of the photovoltaic cover plate 21, and the side of the slide plate 27 is fixedly installed with a combination plate 28. The other end of the bimetallic coil spring 24 is in contact with the combination plate 28. The bottom of the combination plate 28 is slidably connected to the adjustment shaft 25. The inner wall of the photovoltaic cover plate 21 and on both sides of the slide plate 27 are fixedly installed with a limit plate 29.

[0043] The bimetallic coil spring 24 is heated and expanded to move the combination sheet 28 and the slide plate 27. Due to the existence of the limit plate 29, the movement range of the slide plate 27 is limited. The combination sheet 28 is divided into an upper and lower part. The upper part of the combination sheet 28 is made of a copper sheet, which is in contact with the bimetallic coil spring 24. The lower part of the combination sheet 28 is made of a steel sheet. A notch is provided at the end of the adjustment shaft 25, and the steel sheet is located in the notch.

[0044] After the slide plate 27 moves to the extreme position, the elastic force of the bimetallic spring 24 cannot push the slide plate 27. At this time, the bimetallic spring 24 is deformed and bent by the reaction force of the slide plate 27 to avoid the slide plate 27. The continued bending of the bimetallic spring 24 can no longer affect the position of the slide plate 27. The bimetallic spring 24 avoids the slide plate 27 to prevent the bimetallic spring 24 from being continuously stressed and causing elastic fatigue, which cannot be recovered. The movable range of the slide plate 27 affects the rotation angle of the adjustment shaft 25, thereby limiting the reflection range of the focusing mirror 26 and avoiding the adjustment shaft 25 from rotating too much, causing the focusing mirror 26 to reflect light to the outside of the photovoltaic cover 21, causing light pollution and affecting the newlyweds.

[0045] When the bimetallic coil spring 24 is heated to a high temperature, the bimetallic coil spring 24 expands to push the combination sheet 28 to rotate the adjustment shaft 25, so that the focusing mirror 26 is staggered with the photovoltaic cell 22, avoiding continuous temperature rise and shortening the service life of the photovoltaic cell 22. As the bimetallic coil spring 24 continues to expand, the slide plate 27 moves to the limit position, and the bimetallic coil spring 24 deforms to avoid the combination sheet 28. When the bimetallic coil spring 24 is heated to a low temperature, the bimetallic coil spring 24 contracts and pulls back the combination sheet 28, so that the focusing mirror 26 irradiates the photovoltaic cell 22. A magnetic strip is provided at the inner center of the combination sheet 28.

[0046] like Figure 3 and Figure 4 As shown, a mesh cloth 210 is fixedly installed on the bottom of the skateboard 27, and the mesh cloth 210 slides left and right on the inner wall of the photovoltaic sealing panel 21. A plurality of exhaust holes are provided on the back of the photovoltaic sealing panel 21. An electrostatic plastic sheet is fixedly installed on the mesh cloth 210. A plurality of electrostatic plastic sheets are provided, and the plurality of electrostatic plastic sheets are equidistantly distributed in a straight line, and the positions of the electrostatic plastic sheets correspond to the positions of the exhaust holes.

[0047] When the temperature is low, during the movement of the skateboard 27, the skateboard 27 drives the mesh 210 to move, so that the electrostatic plastic sheet on the mesh 210 moves to the exhaust hole, and the mesh 210 is adsorbed on the photovoltaic sealing panel 21, thereby improving the sealing effect, thereby increasing the temperature inside the photovoltaic sealing panel 21; when the temperature is high, the skateboard 27 drives the mesh 210 to move, so that the mesh 210 avoids the exhaust hole, thereby improving the air permeability inside the photovoltaic sealing panel 21.

[0048] In this embodiment, when the temperature inside the photovoltaic sealing plate 21 is high, the bimetallic coil spring 24 unfolds and pushes the combination piece 28 to rotate the adjustment shaft 25 counterclockwise, so that the focusing mirror 26 is hidden inside the photovoltaic sealing plate 21, and the light focused by the focusing mirror 26 is prevented from irradiating the photovoltaic cell 22, thereby shortening the service life of the photovoltaic cell 22. When the temperature inside the photovoltaic sealing plate 21 is low, the combination piece 28 rotates clockwise, and the focusing mirror 26 reflects and focuses the light, thereby increasing the temperature inside the photovoltaic sealing plate 21 and improving the light intensity received by the photovoltaic cell 22.

[0049] Embodiment 2, based on embodiment 1, this embodiment proposes a photovoltaic module, such as Fig. 9 and Fig.10 As shown, a wiring assembly 5 is fixedly installed on the side of the photovoltaic cover plate 21, and the wiring assembly 5 includes a junction box 51, an upstream line 53 and a downstream line 54. The upstream line 53 and the downstream line 54 are fixedly installed on both ends of the junction box 51, and the ends of the upstream line 53 and the downstream line 54 are electrically connected to the photovoltaic cell 22. A plurality of photovoltaic panels 2 are provided.

[0050] The photovoltaic panel 2 located above is connected to the upstream line 53 on the photovoltaic panel 2 located below through the downstream line 54, so as to connect multiple photovoltaic components to transmit the electricity generated by all photovoltaic components to the battery.

[0051] like Fig.10 As shown, an iron core 52 is fixedly installed at both upper and lower ends of the junction box 51, and the uplink line 53 and the downlink line 54 are respectively wound around the two iron cores 52. A baffle 55 is slidably connected to the inner wall of the longitudinal support column 1, and an air spring is fixedly installed between the end of the baffle 55 and the longitudinal support column 1. When the baffle 55 is fully extended, the baffle 55 contacts the side of the junction box 51.

[0052] An electromagnet is formed by winding an up line 53 and a down line 54 around two iron cores 52 respectively. The electromagnet attracts the baffle 55 so that the baffle 55 blocks and fixes the position of the junction box 51, thereby fixing the position of the photovoltaic cover 21. During maintenance, when a photovoltaic module has a problem, no current flows in the up line 53 and the down line 54 connected to it.

[0053] In this embodiment, an electromagnet is formed by winding an up line 53 and a down line 54 around two iron cores 52 respectively, and the electromagnet is used to attract the baffle 55 so that the baffle 55 blocks and fixes the position of the junction box 51, thereby fixing the position of the photovoltaic cover plate 21. If a photovoltaic module in the photovoltaic curtain wall has a problem, the baffle 55 is reset under the action of the air spring, and the baffle 55 on it is misaligned with the junction box 51 for maintenance.

[0054] Embodiment 3, based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a photovoltaic module, such as Figures 5 to 7As shown, the transverse support column 4 includes a column 41, a clamping block 42, a spring sheet 43, a tooth plate 44, a transmission assembly, a stud 47, an adjustment plate 48 and a positioning plate 49. The inner wall of the column 41 is slidably connected to the clamping block 42, and the spring sheet 43 is elastically connected between the clamping block 42 and the column 41. The tooth plate 44 is fixedly installed on the side of the clamping block 42, and the end of the stud 47 is rotatably connected to the longitudinal support column 1. The tooth plate 44 is connected to the stud 47 through the transmission assembly, and the middle part of the stud 47 is threadedly connected to the adjustment plate 48. The side of the adjustment plate 48 is slidably connected to the stud 47. An inclined surface is provided on the top of the clamping block 42, and the photovoltaic sealing panel 21 contacts the clamping block 42. The clamping block 42 is fixedly installed in the column 41, and the adjustment plate 48 slides back and forth on the inner wall of the longitudinal support column 1.

[0055] like Figure 8 As shown, the transmission assembly includes a gear 45 and a bevel gear 46, the gear 45 is coaxially connected with the bevel gear 46, the end height of the stud 47 is installed with a docking bevel gear, the bevel gear 46 is meshed with the docking bevel gear, the rotating shaft on the gear 45 and the bevel gear 46 is rotatably connected to the longitudinal support column 1, and the bottom of the column 41 is slidably connected with a welding plate 3.

[0056] The photovoltaic sealing panel 21 is placed on the column 41, and the bottom of the photovoltaic sealing panel 21 squeezes the clamp 42, and the clamp 42 moves to avoid the photovoltaic sealing panel 21. The clamp 42 uses the tooth plate 44 to drive the gear 45 and the bevel gear 46 to rotate, so that the stud 47 rotates to change the position of the adjustment plate 48, so that a surface on the positioning plate 49 is in the same plane as the surface of the photovoltaic sealing panel 21.

[0057] A pressure plate 410 is connected to the inside of the column 41 so as to slide up and down. A supporting spring 411 is fixedly installed at the bottom of the pressure plate 410. A transfer rod 412 is fixedly installed at the bottom of the supporting spring 411. The other end of the transfer rod 412 is fixedly connected to the positioning plate 49. The positioning plate 49 and the baffle 55 are respectively located on both sides of the photovoltaic sealing plate 21, and the photovoltaic sealing plate 21 is pressed on the pressure plate 410.

[0058] When the pressing plate 410 is pressed down by the photovoltaic sealing plate 21 to reach the limit position, the pressing plate 410 uses the supporting spring sheet 411 to push the transfer rod 412, and the transfer rod 412 pulls out the positioning plate 49 to clamp the photovoltaic sealing plate 21, thereby positioning and installing the photovoltaic sealing plate 21.

[0059] In this embodiment, the photovoltaic sealing panel 21 is used to squeeze the clamp block 42 to generate displacement. The thicker the photovoltaic sealing panel 21 is, the greater the distance the clamp block 42 moves, so that the rotation angle of the stud 47 is larger. The stud 47 is used to rotate and adjust the position of the adjustment plate 48 and the positioning plate 49. The photovoltaic sealing panel 21 is used to press down the pressure plate 410 to move the transfer rod 412 to pop out the positioning plate 49 to adapt to the thickness of the photovoltaic sealing panel 21 and position and support the photovoltaic sealing panel 21, thereby achieving adaptation to photovoltaic sealing panels 21 of different thicknesses and positioning and installation.

[0060] The photovoltaic curtain wall in this embodiment is formed by connecting a plurality of photovoltaic modules to each other.

[0061] The above specific embodiments are only several optional embodiments of the present invention.
