[0002] With the development of photovoltaic technology, heterojunction (HJT) bifacial photovoltaic modules have been widely used in industrial and commercial distributed photovoltaic fields due to their high conversion efficiency, low temperature coefficient, and excellent bifacial power generation performance. To fully leverage their bifacial power generation advantages, vertical installation is gaining increasing attention, and these devices are mostly installed on industrial and commercial concrete flat roofs with good load-bearing capacity.

[0003] Currently, most brackets used to fix photovoltaic modules on the market use traditional clamps and bolts for fastening. During installation and disassembly, operators need to use tools to tighten or loosen a large number of bolts, nuts, clamps, and other fasteners one by one. The process is tedious, time-consuming, and physically demanding. In addition, problems such as stripped fasteners and loss also exist during the operation.

[0004] Therefore, a heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs, which simplifies the assembly and disassembly process, eliminates the need for a large number of tools and fasteners, and enables rapid installation and disassembly of the photovoltaic panel body, effectively reducing the labor intensity of installers; at the same time, it can prevent problems such as stripping or loss of fasteners.

[0006] This utility model is implemented as follows: a heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs includes a flat plate and a photovoltaic panel body with a frame, wherein a limiting mechanism is provided on the upper side of the flat plate.

[0007] The limiting mechanism includes a vertical plate fixedly connected to the upper end of the flat plate. A positioning groove is opened through the outer wall of the vertical plate. A fixed limiting frame is fixedly connected to the left end of the vertical plate. Two fixed plates are fixedly connected to the upper end of the flat plate. A movable rod is rotatably connected between the two fixed plates. A connecting frame is fixedly connected to the outer wall of the movable rod. A movable limiting frame is fixedly connected to the left end of the connecting frame.

[0008] A locking mechanism is provided on the outside of the movable limiting frame. The locking mechanism includes an L-shaped plate fixedly connected to the right end of the movable limiting frame. A connecting plate is fixedly connected to the upper end of the L-shaped plate. A circular hole is opened through the upper end of the connecting plate. A sliding column is inserted through the circular hole. A limiting hole is opened at the lower end of the sliding column. A limiting column inserted into the limiting hole is fixedly connected to the upper end of the upright plate. A connecting ring is fixedly connected to the outer wall of the sliding column. A compression spring is fixedly connected between the connecting ring and the connecting plate.

[0009] A counterweight mechanism is provided on the lower side of the plate.

[0010] As a preferred embodiment of the heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs according to this utility model, the counterweight mechanism includes a cement base, and two mounting plates are fixedly connected to the upper side of the cement base by multiple pre-embedded bolts. Multiple support rods are fixedly connected to the upper ends of the two mounting plates, and the multiple support rods are fixedly connected to the flat plate.

[0011] As a preferred embodiment of the heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs according to this utility model, the outer wall of the sliding column is provided with two sliding grooves, and the interior of each of the two sliding grooves is slidably connected with a slider that is fixedly connected to the inner wall of the circular hole.

[0012] As a preferred embodiment of the heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs according to this utility model, the upper end of the limiting column is fixedly connected with a conical guide head.

[0013] As a preferred embodiment of the heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs according to this utility model, a baffle is fixedly connected to the upper end of the sliding column.

[0014] In a preferred embodiment of this utility model, a heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs, the compression spring is sleeved on the outside of the sliding column.

[0015] As a preferred embodiment of the heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs according to this utility model, the distance between the left and right sides of the vertical plate is equal to the distance between the left and right sides of the frame.

[0016] The beneficial effects of this utility model are:

[0017] 1. During installation, the operator first places the photovoltaic panel and its frame into the positioning slot for initial positioning. After the frame is aligned with the fixed limiting frame, the photovoltaic panel is prevented from moving to the left. Then, the movable limiting frame is lifted upwards, causing it to rotate counterclockwise around the movable rod until the movable limiting frame is simultaneously aligned with the right end of the frame and the upright plate, thus confining the photovoltaic panel in the predetermined position. During the lifting of the movable limiting frame, the sliding column is pulled, compressing the spring. Then, the tension on the sliding column is released, and the spring force pushes the sliding column downwards, allowing the limiting hole to engage with the limiting column and complete the locking process. Through the cooperation of the limiting mechanism and the locking mechanism, problems such as stripped or lost fasteners in traditional installations are completely avoided.

[0018] 2. When disassembly is required, simply pull the sliding column upwards to disengage the limiting hole from the limiting column to release the locking state. Then, lower the movable limiting frame and rotate it clockwise to open it, allowing the photovoltaic panel to be removed. This installation and disassembly process significantly simplifies the operation steps, enabling rapid assembly and disassembly of the photovoltaic panel and effectively reducing the labor intensity of installers.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-5 A heterojunction vertical bifacial photovoltaic module support for industrial and commercial roofs includes a flat plate 1 and a photovoltaic panel body 2 with a frame 3, wherein a limiting mechanism is provided on the upper side of the flat plate 1.

[0028] The limiting mechanism includes a vertical plate 4 fixedly connected to the upper end of the flat plate 1. A positioning groove 5 is provided through the outer wall of the vertical plate 4. A fixed limiting frame 6 is fixedly connected to the left end of the vertical plate 4. Two fixed plates 7 are fixedly connected to the upper end of the flat plate 1. A movable rod 8 is rotatably connected between the two fixed plates 7. A connecting frame 9 is fixedly connected to the outer wall of the movable rod 8. A movable limiting frame 10 is fixedly connected to the left end of the connecting frame 9.

[0029] A locking mechanism is provided on the outside of the movable limiting frame 10. The locking mechanism includes an L-shaped plate 11 fixedly connected to the right end of the movable limiting frame 10. A connecting plate 12 is fixedly connected to the upper end of the L-shaped plate 11. A circular hole 13 is opened through the upper end of the connecting plate 12. A sliding post 14 is inserted through the circular hole 13. A limiting hole 16 is opened at the lower end of the sliding post 14. A limiting post 17 inserted into the limiting hole 16 is fixedly connected to the upper end of the upright plate 4. A connecting ring 18 is fixedly connected to the outer wall of the sliding post 14. A compression spring 15 is fixedly connected between the connecting ring 18 and the connecting plate 12.

[0030] A counterweight mechanism is provided on the underside of the plate 1.

[0031] In this embodiment: In the initial state, the movable limiting frame 10 is in the open position. During installation, the operator first places the photovoltaic panel body 2 and the frame 3 into the positioning groove 5. The frame 3 and the positioning groove 5 cooperate with each other, thereby providing initial positioning for the photovoltaic panel body 2 and the frame 3. When the frame 3 is in contact with the right end of the fixed limiting frame 6, the fixed limiting frame 6 prevents the photovoltaic panel body 2 and the frame 3 from moving to the left. At this time, the right end of the frame 3 is coplanar with the right end of the upright plate 4. Subsequently, the operator lifts the movable limiting frame 10 upwards, causing the connecting frame 9 to rotate counterclockwise around the movable rod 8 until the movable limiting frame 10 is simultaneously in contact with the right ends of the frame 3 and the upright plate 4, thereby vertically limiting the photovoltaic panel body 2 to the predetermined position. During the process of lifting the movable limiting frame 10, the sliding column 14 needs to be pulled to move. The compression spring 15 is compressed through the connecting ring 18 and the connecting plate 12. When the movable limiting frame 10 is in contact with the right ends of the frame 3 and the upright plate 4, the limiting column 17 and the limiting hole 16 are aligned. Then, the tension on the sliding post 14 is released, and the elastic force of the compression spring 15 pushes the sliding post 14 downward until the limiting hole 16 fits into the outer wall of the limiting post 17. Through the cooperation between the limiting hole 16 and the limiting post 17, the position of the movable limiting frame 10 is locked, preventing it from rotating open. Through the cooperation of the above-mentioned limiting mechanism and locking mechanism, problems such as stripped fasteners and loss in traditional installation are completely avoided.

[0032] When it is necessary to disassemble the photovoltaic panel, simply pull the sliding column 14 upwards to disengage the limiting hole 16 from the limiting column 17, thereby releasing the locking state of the movable limiting frame 10. Then, lower the movable limiting frame 10, causing the connecting frame 9 to rotate clockwise with the movable rod 8, which opens the movable limiting frame 10, allowing the photovoltaic panel body 2 to be removed. Combined with the above-described limiting installation steps for the photovoltaic panel body 2, the disassembly and assembly process is simplified, eliminating the need for numerous tools and fasteners, enabling rapid installation and disassembly of the photovoltaic panel body 2, and effectively reducing the labor intensity of installers.

[0033] As a technical optimization of this utility model, the counterweight mechanism includes a cement base 19. Two mounting plates 20 are fixedly connected to the upper side of the cement base 19 by multiple pre-embedded bolts. Multiple support rods 21 are fixedly connected to the upper ends of the two mounting plates 20, and the multiple support rods 21 are fixedly connected to the plate 1.

[0034] In this embodiment, the cement base 19 of the counterweight mechanism is connected to the mounting plate 20 by pre-embedded bolts, and the mounting plate 20 is fixedly connected to the plate 1 by multiple support rods 21. Due to the counterweight effect provided by the cement base 19, sufficient anti-overturning force is provided for the entire device.

[0035] As a technical optimization of this utility model, the outer wall of the sliding column 14 is provided with two sliding grooves, and the inner wall of the two sliding grooves is slidably connected to a slider that is fixedly connected to the inner wall of the circular hole 13.

[0036] In this embodiment, the sliding grooves are respectively engaged with the two sliders to prevent the sliding post 14 from shifting when moving up and down, thus ensuring that the limiting post 17 can accurately enter the interior of the limiting hole 16.

[0037] As a technical optimization of this utility model, a tapered guide head is fixedly connected to the upper end of the limiting post 17.

[0038] In this embodiment, the tapered guide head at the upper end of the limiting post 17 provides guidance when the sliding post 14 falls. The tapered surface can guide the limiting post 17 into the limiting hole 16, reducing the difficulty of alignment.

[0039] As a technical optimization of this utility model, a baffle is fixedly connected to the upper end of the sliding column 14.

[0040] In this embodiment, a baffle is provided to prevent the sliding column 14 from slipping out of the circular hole 13.

[0041] As a technical optimization of this utility model, the compression spring 15 is sleeved on the outside of the sliding column 14.

[0042] In this embodiment: Since the compression spring 15 is sleeved on the outside of the sliding post 14, the sliding post 14 provides a guiding effect for the compression spring 15, preventing the compression spring 15 from twisting during operation.

[0043] As a technical optimization of this utility model, the distance between the left and right sides of the upright plate 4 is equal to the distance between the left and right sides of the frame 3.

[0044] In this embodiment: Since the distance between the left and right sides of the upright plate 4 is equal to the distance between the left and right sides of the frame 3, when the movable limiting frame 10 is in a vertical state, it can simultaneously fit with the right end of the frame 3 and the upright plate 4.

[0045] The working principle and usage process of this utility model are as follows: In the initial state, the movable limiting frame 10 is in the open position. During installation, the operator first places the photovoltaic panel body 2 and the frame 3 into the positioning groove 5. The frame 3 and the positioning groove 5 cooperate with each other, thereby providing initial positioning for the photovoltaic panel body 2 and the frame 3. When the frame 3 is in contact with the right end of the fixed limiting frame 6, the fixed limiting frame 6 prevents the photovoltaic panel body 2 and the frame 3 from moving to the left. At this time, the right end of the frame 3 is coplanar with the right end of the upright plate 4. Subsequently, the operator lifts the movable limiting frame 10 upwards, causing the connecting frame 9 to rotate counterclockwise around the movable rod 8 until the movable limiting frame 10 is simultaneously in contact with the right ends of the frame 3 and the upright plate 4, thereby vertically limiting the photovoltaic panel body 2 in the predetermined position. During the lifting of the movable limiting frame 10, the sliding column 14 needs to be pulled to move. The connecting ring 18, in conjunction with the connecting plate 12, compresses the compression spring 15. When the movable limiting frame 10 is in contact with the right end of the frame 3 and the upright plate 4, the limiting column 17 and the limiting hole 16 are aligned. Then, the tension on the sliding column 14 is released, and the elastic force of the compression spring 15 pushes the sliding column 14 downwards until the limiting hole 16 fits into the outer wall of the limiting column 17. Through the mutual cooperation of the limiting hole 16 and the limiting column 17, the position of the movable limiting frame 10 is locked, preventing it from rotating open. Through the cooperation of the above limiting and locking mechanisms, problems such as stripped or lost fasteners in traditional installations are completely avoided.

[0046] When it is necessary to disassemble the photovoltaic panel, simply pull the sliding column 14 upwards to disengage the limiting hole 16 from the limiting column 17, thereby releasing the locking state of the movable limiting frame 10. Then, lower the movable limiting frame 10, causing the connecting frame 9 to rotate clockwise with the movable rod 8, which opens the movable limiting frame 10, allowing the photovoltaic panel body 2 to be removed. Combined with the above-described limiting installation steps for the photovoltaic panel body 2, the disassembly and assembly process is simplified, eliminating the need for numerous tools and fasteners, enabling rapid installation and disassembly of the photovoltaic panel body 2, and effectively reducing the labor intensity of installers.

[0047] The cement base 19 of the counterweight mechanism is connected to the mounting plate 20 by pre-embedded bolts. The mounting plate 20 is fixedly connected to the plate 1 by multiple support rods 21. Due to the counterweight effect provided by the cement base 19, the entire device is provided with sufficient anti-overturning force.
