Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic glass curtain walls, and in particular to a photovoltaic unit integrated glass curtain wall structure. Background Art

[0002] A photovoltaic unit-integrated glass curtain wall is a building structure that integrates a solar power generation system with the building's exterior curtain wall. It typically integrates photovoltaic modules (solar cells) between double layers of glass, creating photovoltaic glass. This photovoltaic glass then serves as the curtain wall's substrate and is nested within the curtain wall's frame structure, creating a complex structure that both generates electricity and serves as a building curtain wall.

[0003] Currently, photovoltaic glass curtain wall facades in high-rise buildings are primarily installed using fixed frames. First, multiple vertical beams are installed at equal intervals along the building's exterior wall. Horizontal beams are then secured between the vertical beams, creating multiple independent mounting frames. Next, the photovoltaic glass is embedded in a matching frame, which is then installed within the frame and securely fastened with bolts. To address wind resistance, maintenance, and wind noise concerns in high-rise buildings, all external bolted joints and gaps are sealed with sealant after installation. This prevents rainwater erosion and rust while ensuring the wall's smoothness.

[0004] However, in low-rise buildings, photovoltaic glass curtain walls have a relatively small area and are easily affected by the shadows cast by surrounding buildings, resulting in low light utilization. To improve light utilization, adjustable photovoltaic glass angles have become an effective solution. Since low-rise buildings are less affected by wind and relatively simple to maintain, they offer the possibility of implementing photovoltaic glass angle adjustment. While some technical solutions currently exist that can achieve photovoltaic glass angle adjustment, these solutions often overlook the exposure of the curtain wall frame after adjustment, resulting in poor dust and water protection, which in turn accelerates the aging and corrosion of the curtain wall frame and connecting structures. Therefore, these solutions are not comprehensive and practical in actual application.

[0005] In view of this, it is necessary to design a photovoltaic unit integrated glass curtain wall structure, which can not only realize the angle adjustment function of the photovoltaic glass, but also effectively prevent dust and water during the adjustment process. Summary of the Invention

[0006] The object of the present invention is to provide a photovoltaic unit integrated glass curtain wall structure to solve the problems described in the background art.

[0007] The technical solution of the present invention is achieved in this way:

[0008] A photovoltaic unit integrated glass curtain wall structure includes a curtain wall frame formed by fixedly connecting multiple vertically arranged vertical beams and multiple horizontally arranged cross beams. The curtain wall frame includes multiple rectangular installation frames, and each installation frame is jointly clamped by two adjacent vertical beams on the left and right and two adjacent cross beams on the top and bottom. A groove frame is fixedly arranged around the inner frame wall of the installation frame, and a groove is formed by surrounding and opening on the inner frame surface of the groove frame from the inside to the outside. An annular grooved rubber strip is fixedly arranged in the groove, and a glue groove is formed by surrounding and opening on the inner side surface of the grooved rubber strip from the inside to the outside. A photovoltaic glass is also arranged inside the groove frame, and a frame is sleeved on the edge of the photovoltaic glass. A hollow rubber strip is also arranged around the outer frame surface of the frame. The hollow rubber strip is arranged in the glue groove of the grooved rubber strip, and the outer side surface of the hollow rubber strip is in contact with the groove wall of the glue groove. The front and rear width of the glue groove is greater than the front and rear width of the hollow rubber strip. Middle connectors are respectively fixedly arranged at the center of the rear frame surface at the top and the center of the rear frame surface at the bottom of the frame. The middle connector at the top of the frame is horizontally rotatably connected to the bottom of the upper cross beam of the installation frame, and the middle connector at the bottom of the frame is horizontally rotatably connected to the top of the lower cross beam of the installation frame. Side connectors are respectively fixedly arranged on the left and right sides of the center of the rear frame surfaces at the top and bottom of the frame, a total of four side connectors. Three side connectors are horizontally rotatably connected with telescopic rods, and the other ends of the telescopic rods are horizontally rotatably connected to the vertical beam behind the frame. One side connector is horizontally rotatably connected with an electric push rod, and the other end of the electric push rod is horizontally rotatably connected to the vertical beam behind the frame.

[0009] When using the above solution, when it is necessary to rotate the photovoltaic glass, control the electric push rod to extend or retract, and the photovoltaic glass rotates with the middle connector as the rotation center, so as to change the angle of the photovoltaic glass and absorb light energy more efficiently. When the electric push rod does not act, the length of the electric push rod remains fixed, thus ensuring that the frame cannot rotate and is in a fixed state.

[0010] When adopting the above structure, the front and rear width of the glue groove is greater than the front and rear width of the hollow rubber strip. Within a certain rotation angle, whether the frame is in a straight state or an angled state, the hollow rubber strip on the outer frame surface of the frame always contacts the grooved rubber strip in the groove frame, and the structure of the hollow rubber strip can also effectively always be close to the glue groove through its own compression deformation, so as to achieve the effect of sealing the installation frame and prevent dust and rainwater from entering the interior of the curtain wall structure through the installation frame.

[0011] A further technical solution is that through holes are respectively opened at the centers of the upper and lower cross beams of the installation frame, and the through holes penetrate through the upper and lower end faces of the cross beams. The middle connector is a middle connecting plate, and a middle shaft hole penetrating through the upper and lower end faces of the middle connecting plate is opened on the middle connecting plate. A bearing is also arranged in the middle shaft hole, a bushing is also arranged between the middle connecting plate and the cross beam, a middle shaft bolt is also arranged in the cross beam, and the middle shaft bolt sequentially passes through the bearing in the middle connecting plate below the cross beam, the bushing below the cross beam, the through hole of the cross beam, the bushing above the cross beam, and the bearing in the middle connecting plate above the cross beam from bottom to top and is screwed with a nut. The middle shaft bolt is rotationally connected with the bearing and the bushing.

[0012] When using the above solution, the frame rotates around the central axis bolt, and the errors during the installation of the mounting crossbeam and the middle connecting plate of the frame are adjusted by setting the bushing. At the same time, this structure can fix the frames above and below the crossbeam, simplifying the installation structure.

[0013] A further technical solution is that the side connecting member is a side connecting plate, on which a side shaft rod is fixedly provided. One end of the telescopic rod is horizontally rotatably connected to the side shaft rod, and one end of the electric push rod is horizontally rotatably connected to the side shaft rod.

[0014] A further technical solution is that a crossbar is also fixedly provided on the vertical beam, and a vertical shaft is also fixedly provided on the crossbar. The other end of the telescopic rod is horizontally rotatably connected to the vertical shaft, and the other end of the electric push rod is horizontally rotatably connected to the vertical shaft.

[0015] A further technical solution is that two non-linear embedding grooves surrounding the entire frame are further provided on the outer frame surface of the frame from outside to inside. The hollow rubber strip includes two non-linear embedding parts and a hollow arc part. The bottom of the hollow arc part is connected to the top of the two non-linear embedding parts. The non-linear embedding parts of the hollow rubber strip are inserted into the non-linear embedding grooves, and the hollow arc part remains outside the outer frame surface of the frame and abuts against the grooved rubber strip.

[0016] When using the above solution, the connection sealing performance between the frame and the hollow rubber strip can be improved by setting the installation method of the non-linear embedding groove and the non-linear embedding part.

[0017] A further technical solution is that an elastic cotton strip is further provided in the hollow arc part.

[0018] When using the above solution, the elasticity of the hollow rubber strip can be improved by setting the elastic cotton strip, and the sealing performance with the grooved rubber strip can be improved.

[0019] A further technical solution is that the groove surface of the rubber groove facing the hollow rubber strip further includes a flat surface and an arc surface. The flat surface is arranged in the middle of the groove surface of the rubber groove facing the hollow rubber strip, and the arc surfaces are respectively arranged at the front and rear ends of the flat surface.

[0020] When using the above solution, by setting the arc surface, the contact surface between the hollow rubber strip and the grooved rubber strip can be increased after the frame rotates, thereby improving the sealing performance.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. Flexible angle adjustment: By extending or retracting the electric push rod, the angle of the photovoltaic glass can be conveniently adjusted, enabling it to absorb light energy more efficiently. When the length of the electric push rod is fixed, the frame remains stable, ensuring the stability and reliability of the system.

[0023] 2. Excellent sealing performance: Since the glue groove is designed wider than the hollow rubber strip, the hollow rubber strip can maintain close contact with the grooved rubber strip whether the frame is straight or inclined. This design not only achieves a good sealing effect but also effectively prevents dust and rainwater from seeping into the curtain wall structure through the installation frame, thus protecting the internal structure of the curtain wall.

[0024] 3. Simplified installation and adjustment: This solution allows the frame to rotate around the central axis bolt, and at the same time, the installation error is adjusted through the bushing. This design not only simplifies the installation process but also can fix the frames on both sides of the upper and lower crossbeams simultaneously, improving the installation efficiency and reducing the installation complexity.
