Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a photovoltaic module installation structure. Background Technology

[0002] Photovoltaic modules, as the core energy conversion unit of a solar photovoltaic power generation system, are mainly assembled from tempered glass, EVA film, solar cells, backsheets, and frames. Their core function is to efficiently convert solar energy into electrical energy, providing clean energy for various electrical devices or the power grid. As the global energy structure accelerates its transformation towards low-carbon and renewable energy, the application scenarios of photovoltaic modules have gradually expanded from traditional large-scale ground-mounted photovoltaic power plants to distributed photovoltaic systems, such as industrial plant roofs, commercial building curtain walls, residential balconies, and agricultural photovoltaic greenhouses.

[0003] According to the search, Chinese patent document CN212137588U discloses a photovoltaic module installation structure. When it is necessary to adjust the angle of the photovoltaic module body, simply start the hydraulic cylinder, and then the oil pump inside the oil tank starts to operate. The oil pump delivers an appropriate amount of oil into the hydraulic chamber through the oil guide pipe, thereby generating hydraulic pressure in the hydraulic chamber. At this time, the piston located inside the hydraulic chamber will move upward under the thrust of the hydraulic pressure, which in turn moves the slide rod upward, thereby adjusting the angle of the photovoltaic module body.

[0004] However, the above-mentioned photovoltaic module installation structure can only adjust the pitch angle of the photovoltaic panel in actual use, while resetting and adjusting its azimuth angle, which has limitations in use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a photovoltaic module installation structure, which has the advantages of being able to adjust both the azimuth angle and the pitch angle of the photovoltaic panel, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module installation structure, comprising two bottom support frames, one of which has a flat plate fixedly connected to its top surface, a C-shaped frame fixedly connected to its top surface, a rotating rod rotatably connected inside the C-shaped frame, a worm gear fixedly connected to one end of the rotating rod, and an ear block rotatably connected to the outer surface of the rotating rod, an azimuth bracket fixedly connected to one end of the ear block rotatably, an azimuth shaft rotatably connected inside the azimuth bracket, a worm gear fixedly connected to one end of the azimuth shaft, and an ear block 2 fixedly connected to the outer circumference of the azimuth shaft, a square frame fixedly connected to one end of the ear block rotatably, a crossbeam bolted to the outer surface of the square frame, an ear block 3 fixedly connected to the outer surface of the azimuth bracket, a connecting rod rotatably connected inside the ear block 3, a sliding block rotatably connected to one end of the connecting rod, and a pitch angle adjustment rod threadedly connected inside the sliding block.

[0007] Preferably, the crossbeam is a C-shaped channel steel plate, and the outer surface of the crossbeam is provided with multiple straight slots. A pressure block is provided on the inner wall of the crossbeam, and a buckle plate is bolted to the top of the pressure block. The buckle plate is used to fix the photovoltaic panel.

[0008] Preferably, the worm gear transmission is connected to a worm, and a handwheel is fixedly connected to the end of the rotating rod away from the worm.

[0009] Preferably, one end of the azimuth bracket is fixedly connected to two lugs, one of which is rotatably connected to a rotating rod, and the other is rotatably connected to the rotating shaft of a worm gear.

[0010] Preferably, a limiting ring is fixedly connected to the outer surface of the pitch angle adjusting rod, the two ends of the pitch angle adjusting rod are rotatably connected to the bottom support frame, and a handle is fixedly connected to one end of the pitch angle adjusting rod.

[0011] Preferably, one side of the C-shaped frame is engraved with angle lines, a pointer is provided on the outer circumference of the rotating rod near the C-shaped frame, a scale is fixedly connected between the two bottom support frames, and a pointer is also fixedly connected to the outer surface of the sliding block.

[0012] Compared with the prior art, the present invention provides a photovoltaic module installation structure, which has the following advantages: 1. In terms of azimuth angle adjustment, this utility model utilizes a worm gear transmission structure. Rotating the handwheel at the end of the rotating rod drives the photovoltaic panel to rotate. Simultaneously, the pointer on the outer circumference of the rotating rod aligns with the angle markings on the C-shaped frame, allowing direct reading of the adjustment value and avoiding deviations caused by experience-based judgment. For pitch angle adjustment, rotating the handle at the end of the pitch angle adjustment rod moves the sliding block through a threaded connection, thereby pulling the connecting rod to adjust the angle. Furthermore, the pointer on the sliding block corresponds to the scale between the base support frame, allowing indirect control of the pitch angle amplitude through the distance the sliding block moves. This adjustment design with scale indication ensures that multiple photovoltaic modules in the same group are adjusted to the same angle.

[0013] 2. This utility model achieves rapid assembly of photovoltaic panels through the coordinated design of crossbeams, pressure blocks, and buckle plates. During installation, simply place the photovoltaic panel on the upper surface of the crossbeams made of two C-shaped channel steel plates, then fasten the buckle plates to the edge of the photovoltaic panel, and then use bolts to connect the buckle plates to the pressure blocks attached to the inner wall of the crossbeams. This connection method does not require complicated tools or cumbersome procedures, and operators can easily complete the fixing of the photovoltaic panels and brackets. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5A photovoltaic module mounting structure includes two base support frames 1. A flat plate 2 is fixedly connected to the top surface of one of the base support frames 1. A C-shaped frame 3 is fixedly connected to the top surface of the flat plate 2. A rotating rod 4 is rotatably connected inside the C-shaped frame 3. A worm gear 5 is fixedly connected to one end of the rotating rod 4. An ear block 6 is rotatably connected to the outer surface of the rotating rod 4. An azimuth bracket 7 is fixedly connected to one end of the ear block 6. An azimuth shaft 8 is rotatably connected inside the azimuth bracket 7. A worm gear 9 is fixedly connected to one end of the azimuth shaft 8. An ear block 10 is fixedly connected to the outer circumference of the azimuth shaft 8. A square frame 11 is fixedly connected to one end of the ear block 10. A crossbeam 12 is bolted to the outer surface of the square frame 11. An ear block 13 is fixedly connected to the outer surface of the azimuth bracket 7. A connecting rod 14 is rotatably connected inside the ear block 13. A sliding block 15 is rotatably connected to one end of the connecting rod 14. A pitch angle adjustment rod 16 is threadedly connected inside the sliding block 15.

[0018] Specifically, the crossbeam 12 is a C-shaped channel steel plate, and multiple straight slots are opened through the outer surface of the crossbeam 12. A pressure block 17 is provided on the inner wall of the crossbeam 12, and a buckle plate 18 is bolted to the top of the pressure block 17. The buckle plate 18 is used to fix the photovoltaic panel 19.

[0019] The advantage is that by placing the photovoltaic panel 19 on the upper surface of the two crossbeams 12, and then fastening the buckle 18 to the edge of the photovoltaic panel 19, and then using matching screws to connect the buckle 18 to the pressure block 17, the pressure block 17 will fit tightly against the inner wall of the crossbeam 12. This makes it easy and quick to connect the photovoltaic panel 19 to the crossbeam 12, thereby connecting the photovoltaic panel 19 to the entire mounting bracket.

[0020] Specifically, the worm gear 9 is connected to the worm 5, and a handwheel is fixedly connected to the end of the rotating rod 4 away from the worm 5.

[0021] Specifically, one end of the azimuth bracket 7 is fixedly connected to two lugs 6, one of which is rotatably connected to a rotating rod 4, and the other is rotatably connected to the shaft of a worm gear 5.

[0022] The advantage is that when the azimuth angle of the photovoltaic panel 19 needs to be adjusted, the operator turns the handwheel at the end of the rotating rod 4. The handwheel drives the rotating rod 4 and the worm gear 5 to rotate synchronously. The rotating worm gear 5 drives the worm wheel 9 to rotate through tooth meshing. The worm wheel 9 then drives the azimuth angle shaft 8 to rotate inside the azimuth angle bracket 7. The rotation of the azimuth angle shaft 8 will be transmitted to the ear block 10, the square frame 11, and the crossbeam 12 in sequence, and finally drive the photovoltaic panel 19 to achieve the adjustment of the azimuth angle.

[0023] Specifically, a limiting ring is fixedly connected to the outer surface of the pitch angle adjustment rod 16, the two ends of the pitch angle adjustment rod 16 are rotatably connected to the bottom support frame 1, and a handle is fixedly connected to one end of the pitch angle adjustment rod 16.

[0024] The advantage is that when the pitch angle of the photovoltaic panel 19 needs to be adjusted, the operator turns the handle at the end of the pitch angle adjustment rod 16, causing the pitch angle adjustment rod 16 to rotate. Since the sliding block 15 is threadedly engaged with the pitch angle adjustment rod 16, the rotation of the adjustment rod is converted into the linear movement of the sliding block 15 along the axis of the pitch angle adjustment rod 16. When the sliding block 15 moves, it will pull or push the connecting rod 14. The connecting rod 14 then exerts a force on the azimuth bracket 7 through the lug 3 13, causing the azimuth bracket 7 to drive the azimuth axis rod 8 to rotate synchronously. This force is then transmitted to the photovoltaic panel 19 through the frame 11 and the crossbeam 12, thereby realizing the adjustment of the pitch angle of the photovoltaic panel 19.

[0025] Specifically, angle lines are engraved on one side of the C-shaped frame 3, a pointer is set on the outer circumference of the rotating rod 4 near the C-shaped frame 3, a scale 20 is fixedly connected between the two bottom support frames 1, and a pointer is also fixedly connected to the outer surface of the sliding block 15.

[0026] The advantages are that when adjusting the azimuth angle, the rotating rod 4 rotates with the operation, and the pointer on its outer circumference will synchronously correspond to the angle scale line on the C-shaped frame 3. The operator can directly read the azimuth angle adjustment value through the scale line pointed to by the pointer, avoiding the problem of azimuth angle adjustment deviation or inaccuracy caused by relying solely on experience. When adjusting the pitch angle, the sliding block 15 moves along the pitch angle adjustment rod 16, and the pointer on its outer surface will correspond to the scale 20 between the bottom support frames 1. The operator can clearly grasp the moving distance of the sliding block 15 by using the position change of the pointer on the scale 20, thereby indirectly and accurately controlling the adjustment range of the pitch angle, preventing the photovoltaic panel 19 from receiving solar energy due to excessive or insufficient pitch angle adjustment, and ultimately ensuring that multiple photovoltaic modules in the same group can be adjusted to the same pitch angle and azimuth angle.

[0027] In use, the photovoltaic panel 19 is first installed and fixed. The operator places the photovoltaic panel 19 on the upper surface of the two crossbeams 12, then fastens the buckle plate 18 to the edge of the photovoltaic panel 19. Subsequently, the buckle plate 18 is connected to the pressure block 17 attached to the inner wall of the crossbeam 12 using the matching screws, thereby tightly connecting the photovoltaic panel 19 to the crossbeam 12 and forming a stable connection between the photovoltaic panel 19 and the entire mounting bracket. When it is necessary to adjust the azimuth angle of the photovoltaic panel 19, the operator turns the handwheel at the end of the rotating rod 4. The handwheel drives the rotating rod 4 and the worm gear 5 to rotate synchronously. The rotating worm gear 5 drives the worm wheel 9 to rotate through tooth meshing. The worm wheel 9 drives the azimuth angle shaft 8 to rotate inside the azimuth angle bracket 7. The rotation of the azimuth angle shaft 8 is transmitted sequentially to the ear block 10, the square frame 11, and the crossbeam 12, and finally drives the photovoltaic panel 19 to rotate. At the same time, the operator reads the azimuth angle through the pointer on the outer circumference of the rotating rod 4 corresponding to the angle scale line on the side of the C-shaped frame 3. Adjust the values ​​until the photovoltaic panel 19 is adjusted to the required azimuth angle. When the pitch angle of the photovoltaic panel 19 needs to be adjusted, the operator rotates the handle at the end of the pitch angle adjustment rod 16 to rotate the pitch angle adjustment rod 16. Since the sliding block 15 is threadedly engaged with the pitch angle adjustment rod 16, the rotation of the adjustment rod is converted into the linear movement of the sliding block 15 along the axis of the pitch angle adjustment rod 16. When the sliding block 15 moves, it pulls or pushes the connecting rod 14. The connecting rod 14 exerts a force on the azimuth bracket 7 through the lug three 13, causing the azimuth bracket 7 to drive the azimuth axis rod 8 to rotate synchronously. This force is then transmitted to the photovoltaic panel 19 through the frame 11 and the crossbeam 12. During this period, the operator can control the movement distance of the sliding block 15 by observing the pointer on the scale 20 between the two bottom support frames 1 on the outer surface of the sliding block 15, and indirectly control the pitch angle adjustment range until the photovoltaic panel 19 is adjusted to the required pitch angle, ensuring that the pitch angle and azimuth angle of multiple photovoltaic modules in the same group are consistent.
