Description

Technical Field

[0001] This invention relates to the field of photovoltaic module angle adjustment technology, specifically to an angle adjustment mechanism for photovoltaic modules. Background Technology

[0002] Photovoltaic module angle adjustment refers to the dynamic or manual adjustment of the tilt angle and azimuth angle of photovoltaic modules through technical means. The angle directly affects the module's ability to receive direct solar radiation, making it as perpendicular to the sunlight as possible or at the optimal incident angle, thereby maximizing the solar radiation energy received and improving the overall power generation efficiency of the photovoltaic power generation system.

[0003] Traditional photovoltaic module angle adjustment mechanisms have poor overall protection and insufficient environmental adaptability in actual use. In harsh weather conditions such as wind, sand, rain, and snow, the adjustment structure is easily corroded or rusted by debris. After long-term use, it is prone to jamming, reduced adjustment accuracy, and difficulty in maintaining the set working angle of the photovoltaic module, ultimately limiting the overall efficiency improvement of photovoltaic power generation.

[0006] Preferably, the protective mechanism includes a controller, the outer surface of which is fixedly connected to the inner wall of the chassis. A stop block is fixedly connected to the outer surface of one of the pitch axes and the bottom surface of the chassis. Two fixed frames are fixedly connected to the outer surface of the column and the inner wall of the chassis. A sliding plate is slidably connected to the inner wall of each fixed frame. A flexible joint is fixedly connected to the side of each sliding plate away from the fixed frame. A trigger post is fixedly connected to the side of each sliding plate near the fixed frame. A contact switch is fixedly connected to the inner wall of each fixed frame. Two telescopic rods are fixedly connected to the side of each sliding plate near the fixed frame. The end of each telescopic rod away from the sliding plate is fixedly connected to the inner wall of the fixed frame. Two springs are fixedly connected to the side of each sliding plate near the fixed frame. The end of each spring away from the sliding plate is fixedly connected to the inner wall of the fixed frame.

[0007] Preferably, the bottom end of the column is fixedly connected to a mounting base, and the upper surface of the mounting base has six mounting holes.

[0008] Preferably, the upper surface of the mounting base is fixedly connected with three reinforcing blocks, and the outer surface of each reinforcing block is fixedly connected to the outer surface of the column.

[0009] Preferably, each of the two pitch axes is fixedly connected to a support plate at one end that is far apart from the other, and a door is fixedly installed on the inner wall of the chassis.

[0010] Preferably, each of the support plates has a docking block fixedly connected to its upper surface, and each docking block has two docking holes on its upper surface.

[0011] Preferably, a stabilizing plate is rotatably connected to the left end of each input shaft, and the outer surface of each stabilizing plate is fixedly connected to the inner wall of the chassis.

[0012] Preferably, a reinforcing plate is fixedly connected to one side of the two stabilizing plates that are close to each other, and the inner wall of the reinforcing plate is rotatably connected to the left end of the rotating shaft.

[0014] Preferably, the left side of both the pitch reducer and the horizontal reducer is threaded with four bolts, and the right end of each bolt is threaded to the inner wall of the housing.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention, by incorporating an adjustment mechanism, utilizes two servo motors: an upper servo motor for pitch adjustment and a lower servo motor for horizontal adjustment. The upper servo motor drives the corresponding input shaft to rotate via a rotating shaft, pulley, and synchronous belt, thereby driving the pitch reducer to operate. This rotation of the pitch shaft allows the photovoltaic modules mounted on the support plate to adjust their pitch angle. The lower servo motor drives the horizontal reducer via a corresponding transmission structure, causing the rotating gear to mesh with the fixed gear. This, in turn, drives the entire housing to rotate on the column via the first sealed bearing, thus adjusting the horizontal azimuth angle of the photovoltaic modules. The two adjustment processes are independent of each other, allowing for precise adjustment of the photovoltaic modules to the optimal angle, ensuring power generation efficiency. Furthermore, the housing, the first sealed bearing, and the second sealed bearing provide fully enclosed protection for the core transmission components of the adjustment mechanism, preventing external wind, sand, rain, snow, and corrosive debris from entering the transmission meshing parts.

[0016] Secondly, this invention, by incorporating a protective mechanism, utilizes a stop block and a retaining ring. When the adjustment is rotated to its maximum angle, the stop block compresses the flexible joint at the corresponding position. The pressure on the flexible joint causes the sliding plate to retract into the fixed frame. During the movement of the sliding plate, the spring and telescopic rod are compressed until the trigger pin abuts the contact switch. Once the contact switch is triggered, it sends a stop signal to the controller, which then controls the corresponding servo motor to stop operating. This achieves limit position protection for angle adjustment, preventing damage to components due to over-range adjustment. When the rotation reaches the retraction direction, the stop block disengages from compressing the flexible joint, and the spring pushes the sliding plate back to its original position, awaiting the next trigger. This ensures long-term stable operation of the adjustment mechanism under harsh operating conditions and prevents over-travel jamming from affecting adjustment accuracy. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Please see Figs. 1-6An angle adjustment mechanism for photovoltaic modules includes a column 1, an adjustment mechanism 2 and a protective mechanism 3 located above the column 1. The adjustment mechanism 2 includes a housing 201. A first sealed bearing 203 is fixedly connected to the top of the column 1, and the outer ring of the first sealed bearing 203 is fixedly connected to the inner wall of the housing 201. A pitch reducer 204 and a horizontal reducer 205 are respectively arranged on the inner wall of the housing 201. A pitch shaft 206 is fixedly connected to the output end of each pitch reducer 204. A second sealed bearing 207 is fixedly connected to the outer surface of each pitch shaft 206, and the outer ring of each second sealed bearing 207 is fixedly connected to the inner wall of the housing 201. A rotating gear 208 is fixedly connected to the output end of the horizontal reducer 205. A rotating gear 208 is fixedly connected to the upper surface of the column 1. The outer surfaces of the fixed gear 209 and the rotating gear 208 mesh with the outer surface of the fixed gear 209. The input ends of the pitch reducer 204 and the horizontal reducer 205 are both fixedly mounted with couplings 210. The left end of each coupling 210 is fixedly connected with an input shaft 211. The outer surfaces of the pitch reducer 204 and the horizontal reducer 205 are jointly fixedly connected with a fixed plate 202. The outer surface of the fixed plate 202 is fixedly connected to the inner wall of the housing 201. The right side of the fixed plate 202 is fixedly connected with two servo motors 212. The output end of each servo motor 212 is fixedly connected with a rotating shaft 213. The left end of each rotating shaft 213 and the input shaft 211 is fixedly connected with a pulley 214. The outer surface of each set of pulleys 214 is rotatably connected with a synchronous belt 215.

[0021] The bottom end of the column 1 is fixedly connected to the mounting base 4. The upper surface of the mounting base 4 has six mounting holes 5. By setting the mounting base 4 and the mounting holes 5, users can easily fix the entire mechanism in the installation position with screws, ensuring the stability of the device after installation and reducing the probability of tipping over during use.

[0022] Three reinforcing blocks 6 are fixedly connected to the upper surface of the mounting base 4. The outer surface of each reinforcing block 6 is fixedly connected to the outer surface of the column 1. By setting the reinforcing blocks 6, the connection strength between the column 1 and the mounting base 4 can be increased, and the connection between the column 1 and the mounting base 4 can be prevented from loosening and cracking after the column 1 is subjected to long-term force, thereby further improving the overall structural stability of the device.

[0023] Support plates 8 are fixedly connected to the ends of the two pitch axes 206 that are far apart from each other. A door 7 is fixedly installed on the inner wall of the chassis 201. By setting the door 7, users can easily open the chassis 201 to inspect and maintain the internal components without disassembling the entire device, which reduces the difficulty of maintenance work and improves maintenance efficiency. The support plates 8 can provide a stable installation support position for the photovoltaic modules and ensure the structural stability of the photovoltaic modules after installation.

[0024] Each support plate 8 has a fixed connection to a docking block 9 on its upper surface. Each docking block 9 has two docking holes 10 on its upper surface. By setting the docking blocks 9 and docking holes 10, users can quickly align and install the photovoltaic modules with the support plate 8, thereby achieving rapid positioning and fixing of the photovoltaic modules, reducing installation time and improving installation efficiency.

[0025] Each input shaft 211 is rotatably connected to a stabilizing plate 12 at its left end. The outer surface of each stabilizing plate 12 is fixedly connected to the inner wall of the housing 201. By setting the stabilizing plate 12, the left end of the input shaft 211 can be supported and limited to avoid radial displacement during the rotation of the input shaft 211, thus ensuring the stability of the rotation of the input shaft 211 and ensuring the stability of power transmission.

[0026] Two stabilizing plates 12 are fixedly connected to a reinforcing plate 13 on their adjacent sides. The inner wall of the reinforcing plate 13 is rotatably connected to the left end of the rotating shaft 213. By setting the reinforcing plate 13, the left ends of the two rotating shafts 213 can be supported, increasing the structural stability of the rotating shafts 213 during rotation, preventing the rotating shafts 213 from bending and deforming under stress, extending the service life of the rotating shafts 213, and ensuring more stable and reliable power transmission.

[0027] Anti-tilting blocks 11 are fixedly connected to the two support plates 8 on their opposite sides. The upper surface of each anti-tilting block 11 is fixedly connected to the bottom surface of the docking block 9. By setting anti-tilting blocks 11, the connection strength between the docking block 9 and the support plate 8 can be increased, and the docking block 9 can be prevented from breaking and tilting at the connection point after bearing the load of the photovoltaic module for a long time.

[0028] The left side of both the pitch reducer 204 and the horizontal reducer 205 is threaded with four bolts 14. The right end of each bolt 14 is threaded to the inner wall of the housing 201. The bolts 14 can further secure the pitch reducer 204 and the horizontal reducer 205 to the inner wall of the housing 201. Together with the fixing plate 202, they can achieve double fixing, increase the structural stability of the reducer installation, avoid positional displacement during the operation of the reducer, and ensure the transmission meshing accuracy.

[0029] The specific implementation of this embodiment is as follows: In use, the entire device is first installed in the pre-set installation position using the mounting base 4 and mounting holes 5 with fixing screws. Then, the photovoltaic module is aligned with the docking block 9, and the photovoltaic module is positioned and fixed to the support plate 8 through the docking holes 10. The mechanism can then be used normally. When it is necessary to adjust the pitch angle of the photovoltaic module, the servo motor 212 above is started. The servo motor 212 drives the corresponding rotating shaft 213 to rotate. The rotating shaft 213 drives the corresponding input shaft 211 to rotate through the pulley 214 and the synchronous belt 215. The input shaft 211 drives the pitch reducer 2 through the coupling 210. 04 operates, thereby driving the pitch axis 206 to rotate. When the pitch axis 206 rotates, it drives the support plate 8 and the photovoltaic module installed above to rotate, completing the pitch angle adjustment. When it is necessary to adjust the horizontal azimuth angle of the photovoltaic module, the servo motor 212 below is started, which drives the horizontal reducer 205 to operate through the same transmission path. The horizontal reducer 205 drives the rotating gear 208 to rotate. Since the fixed gear 209 is fixed on the column 1, the rotating gear 208 will mesh and rotate along the fixed gear 209 when it rotates, thereby driving the entire chassis 201 to rotate relative to the column 1 through the first sealed bearing 203, completing the horizontal azimuth angle adjustment. Example

[0030] Please see Figs. 1-6 The protective mechanism 3 includes a controller 301, the outer surface of which is fixedly connected to the inner wall of the chassis 201. A stop block 302 is fixedly connected to the outer surface of one of the pitch axes 206 and the bottom surface of the chassis 201. Two fixed frames 303 are fixedly connected to the outer surface of the column 1 and the inner wall of the chassis 201. A sliding plate 304 is slidably connected to the inner wall of each fixed frame 303. A flexible joint 305 is fixedly connected to the side of each sliding plate 304 away from the fixed frame 303. Each sliding plate 304 is close to the fixed frame 303. Each sliding plate 304 has a trigger post 306 fixedly connected to one side, a contact switch 307 fixedly connected to the inner wall of each fixed frame 303, two telescopic rods 308 fixedly connected to the side of each sliding plate 304 near the fixed frame 303, and the end of each telescopic rod 308 away from the sliding plate 304 fixedly connected to the inner wall of the fixed frame 303. Each sliding plate 304 has two springs 309 fixedly connected to the side of each sliding plate 304 near the fixed frame 303, and the end of each spring 309 away from the sliding plate 304 fixedly connected to the inner wall of the fixed frame 303.

[0031] The specific implementation of this embodiment is as follows: During use, when adjusting the pitch, the stop block 302 on the surface rotates synchronously. When the pitch angle reaches the preset maximum range, the stop block 302 will press the flexible joint 305 at the corresponding position. After being pressed, the flexible joint 305 will push the sliding plate 304 to slide inward along the inner wall of the fixed frame 303. During the sliding process, the telescopic rod 308 is compressed, and the spring 309 is also compressed at the same time, until the trigger post 306 on the sliding plate 304 abuts against the contact switch 307. After the contact switch 307 is triggered, it will immediately send a stop signal to the controller 301. After receiving the signal, the controller 301 will control the servo motor 21 corresponding to the pitch adjustment. 2. Stop rotation to prevent the pitch axis 206 from continuing to rotate beyond the adjustment range, causing component jamming or damage; similarly, when the chassis 201 is adjusting the horizontal azimuth angle, the stop block 302 at the bottom of the chassis 201 will rotate synchronously with the chassis 201. After reaching the preset horizontal adjustment limit position, it will also trigger the corresponding contact switch 307, controlling the servo motor 212 corresponding to the horizontal adjustment to stop operating, realizing the limit position protection in the horizontal direction. When the adjustment direction is reversed, after the stop block 302 is released from the pressure on the flexible joint 305, the spring 309 will push the sliding plate 304 to quickly reset, waiting for the next trigger, providing stable and reliable overtravel protection for the adjustment mechanism 2.

[0032] The working principle of this invention is as follows: In use, the entire device is first installed in the pre-set installation position using the mounting base 4 and mounting holes 5 with fixing screws. Then, the photovoltaic module is aligned with the docking block 9, and the photovoltaic module is positioned and fixed to the support plate 8 through the docking holes 10. The mechanism can then be used normally. When it is necessary to adjust the pitch angle of the photovoltaic module, the servo motor 212 above is activated. The servo motor 212 drives the corresponding rotating shaft 213 to rotate. The rotating shaft 213 drives the corresponding input shaft 211 to rotate via the pulley 214 and synchronous belt 215. The input shaft 211 drives the pitch reducer 204 to rotate via the coupling 210. The movement of the servo motor 212 drives the pitch axis 206 to rotate, which in turn drives the support plate 8 and the photovoltaic modules mounted above to rotate, thus adjusting the pitch angle. When the horizontal azimuth angle of the photovoltaic modules needs to be adjusted, the servo motor 212 below is activated, which drives the horizontal reducer 205 through the same transmission path. The horizontal reducer 205 drives the rotating gear 208 to rotate. Since the fixed gear 209 is fixed on the column 1, the rotating gear 208 will mesh with the fixed gear 209 when it rotates, thus driving the entire housing 201 to rotate relative to the column 1 through the first sealed bearing 203, thus adjusting the horizontal azimuth angle. During pitch adjustment, the stop block 302 on the surface rotates synchronously. When the pitch angle reaches the preset maximum range, the stop block 302 will press the flexible joint 305 at the corresponding position. After being pressed, the flexible joint 305 will push the sliding plate 304 to slide inward along the inner wall of the fixed frame 303. During the sliding process, the telescopic rod 308 is compressed, and the spring 309 is also compressed at the same time, until the trigger post 306 on the sliding plate 304 abuts against the contact switch 307. After the contact switch 307 is triggered, it will immediately send a stop signal to the controller 301. After receiving the signal, the controller 301 will control the servo motor 212 corresponding to the pitch adjustment to stop rotating, thus preventing pitch. If shaft 206 continues to rotate beyond the adjustment range, it may cause component jamming or damage. Similarly, when the chassis 201 is adjusted by rotating horizontally, the stop block 302 at the bottom of the chassis 201 will rotate synchronously with the chassis 201. After reaching the preset horizontal adjustment limit position, the corresponding contact switch 307 will be triggered to control the servo motor 212 corresponding to the horizontal adjustment to stop operating, thereby achieving limit position protection in the horizontal direction. When the adjustment direction is reversed, after the stop block 302 is released from the pressure on the flexible joint 305, the spring 309 will push the sliding plate 304 to quickly reset, waiting for the next trigger, thus providing stable and reliable overtravel protection for the adjustment mechanism 2.
