[0005] The purpose of this invention is to provide a flexible photovoltaic carport that uses horizontally arranged steel strands and main support beams to form a roof load-bearing structure, eliminating the need for horizontal purlins and reducing the amount of steel used.

[0006] This utility model is implemented as follows:

[0007] A flexible photovoltaic carport includes a carport support frame. The carport support frame includes main columns arranged horizontally at intervals and main support beams located at the top of the main columns. The main support beams are arranged inclined longitudinally. Several steel strands are arranged at intervals along the length of the two main support beams. The two ends of the steel strands are tightened and anchored to the main support beams. Several longitudinal inclined drainage channels parallel to the main support beams are arranged at intervals on the steel strands between the two main support beams. The longitudinal inclined drainage channels are connected to the steel strands through a first connector. Photovoltaic panel modules are spliced ​​and laid flat on the canopy formed by the main support beams and steel strands through a second connector installed on the longitudinal inclined drainage channels.

[0008] In the aforementioned flexible photovoltaic carport, a transverse drainage channel is provided between adjacent photovoltaic panels at the front and rear, and the transverse drainage channel is connected to the longitudinal inclined drainage channel through a third connector.

[0009] In the aforementioned flexible photovoltaic carport, the second connector includes a crossbeam for supporting the photovoltaic panel assembly. Pressure plates are rotatably connected to both ends of the crossbeam. The inner end of the pressure plate is used to press against the frame. The crossbeam and the pressure plate are locked together by a first fastener. An extension plate for installing a longitudinal inclined drainage channel is symmetrically provided on the bottom surface of the crossbeam.

[0010] In the aforementioned flexible photovoltaic carport, cylindrical rotating shafts are respectively provided at both ends of the crossbeam.

[0011] In the aforementioned flexible photovoltaic carport, the clamping plate further includes a vertical plate, a first horizontal wing plate, and a second horizontal wing plate. The first horizontal wing plate is higher than the second horizontal wing plate. The lower end of the vertical plate is connected to the outer cylindrical surface of the rotating sleeve. One end of the first horizontal wing plate is connected to the upper end of the vertical plate, and the other end is connected to one end of the second horizontal wing plate through an oblique connecting plate. The second horizontal wing plate is pressed onto the frame.

[0012] In the aforementioned flexible photovoltaic carport, the crossbeam includes a central bearing plate and lifting plates located on both sides.

[0031] The present invention will be further described below with reference to specific embodiments:

[0032] like Figure 1-9 As shown, this utility model provides a flexible photovoltaic carport. The flexible photovoltaic carport includes a carport support frame, which includes horizontally spaced main columns 1 and main support beams 2 located at the top of the main columns 1. The main support beams 2 are inclined longitudinally, and several steel strands 3 are spaced along their length on the two main support beams 2. The two ends of the steel strands 3 are tightened and anchored to the main support beams 2. Several longitudinal inclined drainage channels 4 parallel to the main support beams 2 are spaced on the steel strands 3 between the two main support beams 2. In this embodiment, the longitudinal inclined drainage channels 4 are M-shaped drainage channels. The longitudinal inclined drainage channels 4 are connected to the steel strands 3 through a first connector. The photovoltaic panel assemblies 6 are spliced ​​and laid flat on the canopy formed by the main support beams 2 and the steel strands 3 through a second connector installed on the longitudinal inclined drainage channels 4. Furthermore, this utility model also provides horizontal drainage channels 7 below the adjacent ends of the front and rear adjacent photovoltaic panel assemblies 6. The horizontal drainage channels 7 are connected to the longitudinal inclined drainage channels 4 through a third connector.

[0033] This invention utilizes transversely arranged steel strands 3 and main support beams 2 to form a roof load-bearing structure, making the overall support lighter while still meeting structural strength requirements. It eliminates the need for transverse purlins, reducing steel usage, material costs, and processing complexity. Furthermore, a grid-like drainage system is formed by longitudinal inclined drainage channels 4 and transverse drainage channels 7, ensuring that each photovoltaic panel module 6 has a drainage channel around its perimeter, improving drainage efficiency and preventing water accumulation.

[0034] Furthermore, such as Figures 5-8 As shown, the photovoltaic panel assembly 6 includes a frame 5. The second connecting member includes a crossbeam 8 for supporting the frame 5 of the photovoltaic panel assembly 6. A pressure plate 9 is rotatably connected to both ends of the crossbeam 8. The inner end of the pressure plate 9 is used to press against the frame 5. The crossbeam 8 and the pressure plate 9 are locked together by a first fastener. An extension plate 10 for installing a longitudinal inclined drainage channel 4 is symmetrically provided on the bottom surface of the crossbeam 8. The extension plate 10 is detachably and fixedly connected to the longitudinal inclined drainage channel 4 by a second fastener.

[0035] The second connector enables the synchronous fixing of the photovoltaic panel assembly 6 and the longitudinal inclined drainage channel 4, resulting in a compact structure that is easy to assemble and disassemble. Simultaneously, the clamping plate 9 is rotatably connected to both ends of the crossbeam 8, adjustable within an allowable angle range, such as ±15°, making it suitable for fixing the frame 5 of photovoltaic panel assemblies 6 of varying thicknesses. A rigid connection is formed by locking it in place with the first fastener.

[0036] It should be noted that both the first and second fasteners of this utility model are screws.

[0037] Specifically, cylindrical rotating shafts 11 are respectively provided at both ends of the crossarm 8. The axis of the rotating shafts 11 is arranged along the width direction of the crossarm 8. One end of the clamping plate 9 is provided with a rotating sleeve 12 that can be fitted onto the rotating shaft 11. The rotating sleeve 12 is provided with an opening groove 13 to avoid the crossarm 8. The width of the opening groove 13 is greater than the thickness of the crossarm 8. The opening groove 13 facilitates the rotation of the clamping plate 9 around the rotating shaft 11, so as to be suitable for the installation of the frame 5 of photovoltaic panel modules 6 with different thicknesses. In addition, during assembly, the clamping plate 9 can be inserted into both ends of the crossarm 8 along the opening groove 13. The opening size of the opening groove 13 determines the rotation angle of the clamping plate 9.

[0038] In addition, the clamping plate 9 also includes a vertical plate 14, a first horizontal wing plate 15, and a second horizontal wing plate 16. The first horizontal wing plate 15 is higher than the second horizontal wing plate 16. The lower end of the vertical plate 14 is connected to the outer cylindrical surface of the rotating sleeve 12. One end of the first horizontal wing plate 15 is connected to the upper end of the vertical plate 14, and the other end is connected to one end of the second horizontal wing plate 16 through an oblique connecting plate 17. The second horizontal wing plate 16 is pressed onto the frame 5. The structure of the first horizontal wing plate 15, the second horizontal wing plate 16, and the oblique connecting plate 17 can increase strength, and the connection between the second horizontal wing plate 15 and the frame 5 can increase the contact area and improve the connection strength.

[0039] To further improve strength, the first horizontal wing plate 15 and the second horizontal wing plate 16 of this utility model are connected by a reinforcing plate 18, so that the first horizontal wing plate 15, the oblique connecting plate 17 and the reinforcing plate 18 form a triangularly stable structure.

[0040] Meanwhile, this utility model also provides a thickened portion 19 on the first horizontal wing plate 15, and the first fastener passes through the crossbeam 8 and is connected to the thickened portion 19. In this embodiment, the first fastener is a screw. Providing a threaded hole on the thickened portion 19 can increase the threaded connection length of the screw and also avoid the risk of the clamping plate 9 breaking due to stress concentration at the connection with the screw.

[0041] Overall, the clamping plate 9 of this utility model includes a first horizontal wing plate 15, a second horizontal wing plate 16, an oblique connecting plate 17, a reinforcing plate 18, and a thickened part 19. It can reduce weight while ensuring the strength of the clamping plate 9 and reduce material costs.

[0042] like Figure 6 and Figure 7 As shown, this utility model also includes a vertical partition 20 in the middle of the crossarm 8 for positioning the two photovoltaic panel modules 6. The vertical partition 20 serves as a physical separation reference, standardizing the installation spacing of the photovoltaic panel modules 6 on both sides, avoiding cumulative deviations caused by manual measurement, and ensuring the straightness of the overall support system. Simultaneously, the vertical partition 20 also enhances the torsional stiffness of the crossarm 8.

[0043] like Figures 5-7 As shown, in order to enhance the strength of the crossbeam 8, the crossbeam 8 of this utility model includes a central bearing plate 21 and lifting plates 22 located on both sides. The two ends of the central bearing plate 21 are connected to the lifting plates 22 through a ramp transition section 23. The rotating shaft 11 is located at the end of the lifting plate 22, and the extension plate 10 is provided on the bottom surface of the lifting plate 22.

[0044] In addition, such as Figure 4As shown, the structure of the first connecting member of this utility model is as follows: it includes a mounting plate 24 horizontally disposed below the longitudinal inclined drainage channel 4, with both ends of the mounting plate 24 extending beyond the longitudinal inclined drainage channel 4. Clamping plates 25 are respectively provided at both ends of the mounting plate 24, with one end of the clamping plate 25 pressing against the longitudinal inclined drainage channel 4 and the other end pressing against the mounting plate 24. The clamping plate 25 and the mounting plate 24 are connected by U-bolts 26 and locking nuts. The steel strand 3 is threaded through the closed loop formed by the U-bolts 26 and the mounting plate 24, thus realizing the installation of the longitudinal inclined drainage channel 4 and the steel strand 3. This structure allows installers to connect and fix the steel strand 3 to the longitudinal inclined drainage channel 4 inside the carport, eliminating the need to climb to the roof for high-altitude work and significantly reducing construction risks.

[0045] In addition, such as Figure 9 As shown, the third connecting member of this utility model has the following structure: it includes a lower plate 27 attached to the side wall of the longitudinal inclined drainage channel 4, and a bending plate 28 bent and connected to the lower plate 27. An upper plate 29 is provided at the upper end of the bending plate 28 and attached to the upper surface of the transverse drainage channel 7. The lower plate 27 is fixedly connected to the longitudinal inclined drainage channel 4, generally by fasteners (screws, etc.). The third connecting member is located on both sides of the transverse drainage channel 7, and the transverse drainage channel 7 is mounted on the longitudinal inclined drainage channel 4.

[0046] The angle between the lower plate 27, the turning plate 28 and the upper plate 29 is based on the alignment with the longitudinal oblique drainage groove 4 and the transverse drainage groove 7, and can be set according to the actual situation.

[0047] like Figure 1-3 As shown, this utility model also includes a gutter 30, which is arranged horizontally. Two sets of main support beams 2 are symmetrically arranged along the gutter 30. One end of the longitudinal inclined drainage channel 4 of each set faces the gutter 30 to drain water, which can increase the number of parking spaces.

[0048] To increase the lateral width and further increase the number of parking spaces, this utility model provides a middle support beam 31 between the two main support beams 2. The middle support beam 31 is arranged parallel to the main support beams 2, and the middle support beam 30 is supported on the ground by the central column 32.

[0049] In addition, the two main support beams 2 of this utility model are connected to the ground by cable stays 33 to further enhance the strength of the carport.

[0050] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
