Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a photovoltaic sunflower device that is easy to assemble and disassemble. Background Technology

[0002] The solar sunflower is an adjustable photovoltaic energy storage system that uses a global positioning tracking algorithm (sun tracking system) to track the sun's path throughout the day. Even in cloudy weather, the sunflower leaves can move horizontally or vertically to track the sun's position, ensuring that the solar flower maintains the optimal power generation angle with the sun. Furthermore, the solar sunflower is both aesthetically pleasing and practical. It not only provides green electricity to surrounding equipment but also serves as a decorative photovoltaic landscape, adding a beautiful touch to near-zero carbon parks, near-zero carbon communities, near-zero carbon cities, and the construction of low-carbon campuses. This reduces energy consumption and carbon emissions, providing a model for promoting zero-carbon emission reduction.

[0003] However, in the current photovoltaic sunflower installation, the petal-shaped photovoltaic panels need to be fitted one by one onto the outer wall of the drive shaft. The installation of the petal-shaped photovoltaic panels requires multiple people to climb up and assist in the operation. The manpower and material resources required for the installation and removal of the petal-shaped photovoltaic panels are large, resulting in high dismantling costs for the photovoltaic sunflower. Therefore, a photovoltaic sunflower device that is easy to install and remove is proposed. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A photovoltaic sunflower device that is easy to assemble and disassemble, such as Figures 1 to 6 As shown, it includes a photovoltaic base 100, the top of which is equipped with an electric cornering platform to break through multiple sets of petal-shaped photovoltaic panels 110, and the bottom of the photovoltaic base 100 is equipped with a positioning base assembly 200 pre-embedded in the ground.

[0027] The positioning base assembly 200 includes a pre-embedded frame 210 embedded underground. A positioning plate 220, which is mounted on the bottom of the photovoltaic base 100, is slidably installed inside the pre-embedded frame 210. A lead screw 230 connected to the pre-embedded frame 210 is rotatably installed on the lower side of the positioning plate 220. A support beam 221 for driving the positioning plate 220 to rise is threaded on the outer wall of the two sets of lead screws 230. A force plate 250 is fixed inside the lower part of the pre-embedded frame 210 below the petal photovoltaic panel 110. Multiple sets of ball bearings 251 are fixed on the top of the force plate 250. Relief grooves 270 are opened on both sides of the force plate 250 on the inner wall of the pre-embedded frame 210. A frame 280 is slidably installed in each relief groove 270. A storage groove 281 is reserved on the outer wall of the frame 280. An inner lining plate 290 is installed in the storage groove 281.

[0028] The inner lining plate 290 has long straight grooves 291 on both the upper and lower parts. The upper and lower inner walls of the storage groove 281 are fixed with base shafts 283 extending into the long straight grooves 291. The inner wall of the storage groove 281 has a strip groove 282 near the front end for the inner lining plate 290 to slide out.

[0029] The inner side of the clearance groove 270 has L-shaped cable 260. One end of the cable 260 is fixed to the outer wall of the frame 280 and near the bottom. The two sides of the positioning plate 220 are fixed with ear plates 222 that are connected to the other end of the cable 260.

[0030] The embedded frame 210 is equipped with a drive motor 231 for driving the lead screw 230 to rotate. The bottom of the lead screw 230 is rotatably connected to the lower inner wall of the embedded frame 210.

[0031] When installing the petal photovoltaic panel 110, the drive motor 231 can be controlled to work. Its output end drives the lead screw 230 to rotate, and the support beam 221 on its outer wall will drive the positioning plate 220 to be lowered together, so that the lower half of the photovoltaic base 100 enters the pre-embedded frame 210, making its top level moderate. The petal photovoltaic panels 110 can be placed one by one in the pre-embedded frame 210 and made to contact the force plate 250, and then pushed to one side of the photovoltaic base 100. This avoids the dangers of manual climbing operations, saves manpower and material resources required for the installation and disassembly of the device, and achieves the convenience of manual installation and disassembly.

[0032] During storms and heavy rain, the lower half of the photovoltaic base 100 can be positioned within the pre-embedded frame 210, lowering its overall center of gravity and allowing it to better withstand external forces generated by the natural environment. When the positioning plate 220 is lowered, it pulls the cable 260 down simultaneously, dragging the frame 280 up within the clearance groove 270. At this time, the inner lining plate 290 can be manually rotated 90 degrees around the base axis 283, and then pushed towards the center of gravity of the front surface of the petal photovoltaic panel 110. Under the constraint of the base axis 283, the inner lining plate 290 moves through the groove 282 to the front surface of the petal photovoltaic panel 110. A hydrophilic rubber pad can be added to the side of the inner lining plate 290 that contacts the petal photovoltaic panel 110 to increase the connection force between them, thereby protecting the outermost petal photovoltaic panel 110 and allowing it to better withstand severe weather such as storms and heavy rain, thus extending the service life of the photovoltaic sunflower.

[0033] Please refer to this carefully. Figure 2 and Figure 3 The top of the load-bearing plate 250 is curved and concave, and the curvature of the load-bearing plate 250 corresponds to the bottom of the petal photovoltaic panel 110.

[0034] The better fit with the bottom of the petal photovoltaic panel 110, and the use of ball bearing 251 to make the petal photovoltaic panel 110 easier to move forward, make the petal photovoltaic panel 110 easy to install and remove.

[0035] Please refer to this carefully. Figure 3 The inner wall of the clearance groove 270 is provided with an L-groove for the cable 260 to move, and a reversing wheel is provided in the L-groove at the inside corner of the cable 260.

[0036] This allows the cable 260 to move along a preset trajectory, ensuring that the frame 280 rises smoothly and effortlessly.

[0037] Please refer to this carefully. Figure 1 and Figure 2 Multiple sets of drainage holes 240 are provided on both sides of the outer wall of the embedded frame 210. The multiple sets of drainage holes 240 are provided on the outer wall of the embedded frame 210 near the bottom.

[0038] This allows water that enters the pre-embedded frame 210 during rainy days to be discharged into the external drainage ditch through the drainage hole 240.

[0039] Please refer to this carefully. Figure 3 Two sets of guide rods 271 are fixed to the lower inner wall of the recess 270, and blind holes matching the guide rods 271 are opened at the bottom of the frame 280.

[0040] By using the guide rod 271 and the blind hole, the frame 280 is constrained when it is raised, so that it rises straight upward.

[0041] When in use, the drive motor 231 can be controlled to work when installing the petal photovoltaic panel 110. Its output end drives the lead screw 230 to rotate, and the support beam 221 on its outer wall will drive the positioning plate 220 to be lowered together, so that the lower half of the photovoltaic base 100 enters the pre-embedded frame 210, making its top level moderate. The petal photovoltaic panels 110 can be placed one by one in the pre-embedded frame 210 and made to contact the force plate 250, and then pushed to one side of the photovoltaic base 100. This avoids the dangerous risks of manual climbing operation, saves manpower and material resources required for the installation and disassembly of the device, and achieves the convenience of manual installation and disassembly.

[0042] During storms and heavy rain, the lower half of the photovoltaic base 100 can be positioned within the pre-embedded frame 210, lowering its overall center of gravity and allowing it to better withstand external forces generated by the natural environment. When the positioning plate 220 is lowered, it pulls the cable 260 down simultaneously, dragging the frame 280 up within the clearance groove 270. At this time, the inner lining plate 290 can be manually rotated 90 degrees around the base axis 283, and then pushed towards the center of gravity of the front surface of the petal photovoltaic panel 110. Under the constraint of the base axis 283, the inner lining plate 290 moves through the groove 282 to the front surface of the petal photovoltaic panel 110. A hydrophilic rubber pad can be added to the side of the inner lining plate 290 that contacts the petal photovoltaic panel 110 to increase the connection force between them, thereby protecting the outermost petal photovoltaic panel 110 and allowing it to better withstand severe weather such as storms and heavy rain, thus extending the service life of the photovoltaic sunflower.
