Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic power generation structure with regulation and protection functions for zero-carbon industrial parks. Background Technology

[0002] With the global push for carbon neutrality, the construction of zero-carbon industrial parks has become an important direction. As a core clean energy technology, the efficiency and reliability of photovoltaic power generation systems directly affect the optimization of the park's energy structure.

[0003] Traditional photovoltaic (PV) modules experience a significant decrease in cell efficiency at high temperatures. Existing structures suffer from simplistic ventilation designs and low heat dissipation efficiency, leading to shortened cell lifespan. Furthermore, dust, rain, and snow can easily accumulate on the cell surface, impacting overall PV performance. Traditional cleaning methods, relying on manual labor or fixed brushes, are inefficient and lack rapid protective measures in extreme weather, potentially damaging the PV module's surface glass. Current PV panel angle adjustment relies heavily on simple supports or manual operation, failing to track the sun's position based on installation location and seasonal changes, resulting in significant power generation efficiency losses. Additionally, the dispersed arrangement of power generation, energy storage, and conversion modules in current PV modules increases system complexity and maintenance costs. Existing heat dissipation designs often rely on additional equipment, lacking systematic integration. Some solutions use additional heat sinks or fans, increasing energy consumption and making them unsuitable for different climates. Angle adjustment mechanisms often use single motor drives, resulting in poor stability and limited adjustment range.

[0004] In view of this, existing technologies may already provide solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by designing a photovoltaic power generation structure with adjustment and protection functions for zero-carbon industrial parks. This addresses the issues of significant efficiency drops in photovoltaic cells at high temperatures in traditional photovoltaic modules, the limited ventilation design and low heat dissipation efficiency of existing structures leading to shortened cell lifespan, and the tendency for dust, rain, and snow to accumulate on the cell surface, affecting overall photovoltaic performance. Traditional cleaning methods rely on manual labor or fixed brushes, which are inefficient and lack rapid protective measures in extreme weather, potentially damaging the photovoltaic module's surface glass. Furthermore, current photovoltaic panel angle adjustment relies on simple supports or manual operation, failing to track the sun's position based on installation location and seasonal changes, resulting in significant power generation efficiency losses. Additionally, the dispersed arrangement of power generation, energy storage, and conversion modules in current photovoltaic modules increases system complexity and maintenance costs. While existing technologies attempt to improve heat dissipation, dust removal, or adjustment functions independently, they lack systematic integration. Some solutions use additional heat sinks or fans, increasing energy consumption and making them unsuitable for different climates. Angle adjustment mechanisms often use single motor drives, resulting in poor stability and limited adjustment range.

It tracks the solar azimuth angle according to the installation position and seasonal changes to improve power generation efficiency. In the drive cleaning structure, the second motor drives... The lead screw and moving block drive the cleaning brush to move laterally. Simultaneously, through the meshing of the rack and transmission gear, multiple driven gears on the cleaning shafts are linked to achieve a combined rotation and revolution motion of the cleaning brush, efficiently removing surface dust. The covering structure unfolds the protective film through the movement of the moving plate, and combined with the guide roller and traction rod, it quickly covers the photovoltaic panels. With the locking function of the positioning wheel and positioning block, it can quickly protect the photovoltaic modules in extreme weather conditions, reducing the risk of damage to the photovoltaic modules. At the same time, the conversion box integrates the junction box, converter and battery, realizing the integration of power generation, energy storage and power supply, reducing line loss. The bolt installation design of the first frame and the second frame facilitates layered maintenance or replacement of modules, reducing the overall replacement cost, extending the module life, improving power generation efficiency and reducing maintenance frequency.

[0039] The ventilation holes 2 on the side wall of the aluminum frame 1 correspond to the ventilation holes 7 on the side wall of the ventilation frame 6 to form a Venturi effect air duct, thereby achieving active airflow guidance.

[0040] The aluminum frame 1 is made of 6063-T5 high-strength aluminum alloy profile. The side walls are evenly opened with strip-shaped ventilation holes 2.

[0041] During assembly, the first frame 5 is first placed on top of the back plate 4 and abuts against the tops of the four mounting pieces 3. The fixing holes on the side wall of the fixing block 62 engage with the first threaded holes 64 in the mounting grooves 61 on the side wall of the back plate 4, and the back plate 4 is fixed to the lower end of the first frame 5 with bolts. Then, the ventilation frame 6, the second frame 8, and the monocrystalline silicon solar cell 9 are fixed in sequence by bolts engaging with the second threaded holes and the first threaded holes. Finally, the fixing block 62 at the lower end of the first frame 5 is connected to the mounting pieces 3 by bolts engaging with the third threaded hole 66 and the second fixing hole 67. Then, the glass plate 11 is bonded and fixed by the adhesive layer 10. Finally, the third frame 59 is placed on top of the glass plate 11, and the four screws 60 at the four corners of the third frame 59 pass through the glass plate 11, the adhesive layer 10, the monocrystalline silicon cell 9, the second frame 8, the ventilation frame 6, the first frame 5, the back plate 4, and the four corners of the four mounting pieces 3 in sequence. Finally, it is installed with nuts. The whole assembly is assembled by stacking and fixing. In the future, the internal parts can be quickly replaced according to different maintenance and use needs, while ensuring the overall strength of the assembly.

[0042] In the specific implementation process, an adjustment structure is installed at the lower end of the aluminum frame 1. The adjustment structure includes: a support plate 17, a support frame 18, two semi-circular gear rings 19, two connecting shafts 20, two operating rods 21, a base plate 22, a first motor 23, a worm gear 24, a drive shaft 25, a worm wheel 26, a driven shaft 27, two sprockets 28, a chain 29, a drive gear 30, and an auxiliary positioning component.

[0043] Support plate 17 is fixedly installed at the lower end of aluminum frame 1, support frame 18 is fixedly installed at the lower wall of support plate 17, two semi-circular gear rings 19 are fixedly installed on both sides of the lower end of support frame 18, one end of two connecting shafts 20 is respectively embedded in the lower side walls of support frame 18 through bearings, the top ends of two operating rods 21 are respectively movably mounted on the other ends of two connecting shafts 20 through bearings, base plate 22 is fixedly installed at the lower end of two operating rods 21, first motor 23 is fixedly installed on one side of upper end of base plate 22, one end of worm gear 24 is connected to the drive end of first motor 23, and drive shaft 25 is embedded in it through bearings. The lower end of one of the operating rods 21 has a worm gear 26 fixedly installed on one side of the drive shaft 25 and meshing with the worm 24. The driven shaft 27 is embedded in the upper end of one of the operating rods 21 through a bearing. Two sprockets 28 are respectively installed on the upper ends of the drive shaft 25 and the driven shaft 27 and are located inside one of the operating rods 21. The chain 29 is movably fitted above the two sprockets 28. The drive gear 30 is fixedly installed on one side of the driven shaft 27 and meshes with one of the semi-circular gear rings 19. The auxiliary positioning component is fixedly installed on the side wall of the other operating rod 21 and meshes with the other semi-circular gear ring 19.

[0044] When fixing the photovoltaic structure, the workers first fix the aluminum frame 1 to the upper end of the support plate 17. Then, the support frame 18 is connected to the two operating poles 21 through two connecting shafts 20. The bottom ends of the two operating poles 21 are fixed through the base plate 22. Then, the device is moved to the designated position, supported by the base plate 22, and connected to the photovoltaic system. Then, according to the installation position and installation time, the first motor 23 on one side of the upper end of the base plate 22 is driven to work. Under the connection between the first motor 23 and the worm gear 24, the worm gear 24 is driven to rotate. Under the meshing action of the worm gear 24 and the worm wheel 26, the worm wheel 26 and the drive shaft 25 are driven to rotate. The internal rotation of the support pole 21, coupled with the transmission action of the two sprockets 28 and the chain 29, causes the driven shaft 27 and the two sprockets 28 to rotate synchronously. At the same time, the drive gear 30 located outside the driven shaft 27 meshes with one of the semi-circular gear rings 19, which drives the semi-circular gear ring 19 to rotate to one side, causing the bottom end of the support frame 18 to rotate around the connecting shaft 20. This allows for the adjustment of the angle of the support plate 17 and the photovoltaic structure. The angle of the support plate 17 and the photovoltaic module is fixed by the self-locking ability of the worm gear 24 and the worm wheel 26. Subsequently, the angle of the photovoltaic module is adjusted periodically according to the installation position and seasonal changes, without the need for real-time adjustment of the photovoltaic module angle.

[0045] In the specific implementation process, a drive cleaning structure is installed on the upper rear side of the support plate 17. The drive cleaning structure includes: drive frame 31, second motor 32, lead screw 33, moving block 34, mounting bracket 35, rack 36, moving plate 37, guide groove 38, roller 39, transmission gear 40, several cleaning shafts 41, several cleaning brushes 42, and several driven gears 43.

[0046] The drive frame 31 is fixedly installed on the rear wall of the support plate 17. The second motor 32 is fixedly installed on one side of the rear wall of the drive frame 31. The two ends of the lead screw 33 are respectively embedded in the two side walls of the drive frame 31 through bearings, and one end is connected to the drive end of the second motor 32. The moving block 34 is movably embedded in the drive frame 31 and movably fitted above the lead screw 33. The mounting bracket 35 is fixedly installed on the upper wall of the drive frame 31. The rack 36 is fixedly installed on the side wall of the mounting bracket 35. One end of the moving plate 37 is connected to the side wall of the moving block 34. The guide groove... 38 is installed on the front wall of the support plate 17. Roller 39 is installed on the other end of the movable plate 37 through a shaft, and its bottom end is movably embedded in the guide groove 38. Transmission gear 40 is movably installed on one side of the upper end of the movable plate 37 through a shaft, and one side meshes with rack 36. Several cleaning shafts 41 are evenly distributed on the upper end of the movable plate 37 through bearings. Several cleaning brushes 42 are respectively installed on the lower end of several cleaning shafts 41. Several driven gears 43 are respectively installed on the top end of several cleaning shafts 41, and one of the driven gears 43 meshes with transmission gear 40.

[0047] When facing rain or snow, the system first automatically cleans the rain and snow by coordinating the hydrophobic coating 12 on the top of the glass plate 11 with the tilt angle of the photovoltaic module. Then, the second motor 32 on one side of the drive frame 31 is operated. Under the connection between the second motor 32 and the lead screw 33, the lead screw 33 is driven to rotate inside the drive frame 31. Under the meshing action of the internal thread inside the moving block 34 and the lead screw 33, the moving block 34 moves to one side within the drive frame 31, causing the moving plate 37 to move at a uniform speed. At the same time, the roller 39 on the other side of the moving plate 37 moves in the guide groove 38, increasing the overall stability of the moving plate 37. During the movement of the moving plate 37, the transmission gear 40 on one side above the moving plate 37 meshes with the rack 36 on the side wall of the mounting bracket 35, which links the driven gears 43 on multiple cleaning shafts 41 to realize the combined rotation and revolution motion of the cleaning brush 42. As the moving plate 37 moves, the surface of the photovoltaic module is cleaned.

[0048] In the specific implementation process, a covering structure is connected to one side of the movable plate 37. The covering structure includes: two fixed plates 44, a traction rod 45, a connecting frame 46, a guide roller 47, a winding box 48, a third motor 49, a winding shaft 50, a positioning wheel 51, an operating frame 52, a first electric push rod 53, and a positioning block 54.

[0049] Two fixed plates 44 are respectively installed at both ends of the side wall of the movable plate 37.

The first electric push rod 53 is embedded in the operating frame 52. The positioning block 54 is fixedly installed on the telescopic end of the first electric push rod 53, and its top end meshes with the positioning wheel 51.

[0050] As the moving plate 37 moves, the first electric push rod 53 is driven to retract, causing the positioning block 54 to separate from the positioning wheel 51 on one side of the winding shaft 50. As the moving plate 37 moves, the two fixing plates 44 on one side of the moving plate 37 cooperate with the traction rod 45 to move one end of the protective cloth wound on the upper end of the winding shaft 50. The guide roller 47 set on the upper end of the connecting frame 46 supports the other end of the protective cloth, ensuring the gap between the protective cloth and the photovoltaic panel, thereby ensuring the protective buffering effect. When the moving plate 37 moves to the other side, the third motor 49 located on one side of the winding box 48 works, driving the winding shaft 50 to rotate at a specified angle within the winding box 48, performing a small-amplitude winding of the protective cloth to tighten it. Then, the first electric push rod 53 in the operating frame 52 is driven to work, pushing the positioning block 54 to engage with the positioning wheel 51, thereby limiting the rotation of the winding shaft 50. In severe weather such as hail, the protective cloth can effectively block the impact of hail and ensure the overall safety of the photovoltaic module.

[0051] In the specific implementation process, the auxiliary positioning components include: a second electric push rod 55 and a positioning rack 56;

[0052] The second electric push rod 55 is fixedly installed on the side wall of another operating rod 21, and the positioning rack 56 is fixedly installed on the telescopic end of the second electric push rod 55 and meshes with another semi-circular gear ring 19.

[0053] After the angle of the photovoltaic module is adjusted, the angle of the photovoltaic module is initially fixed by the cooperation of the worm gear 26 and worm 24. Then, the second electric push rod 55 is driven to work, pushing the positioning rack 56 to mesh with another semi-circular gear ring 19, and the angle of the photovoltaic module is fixed a second time to ensure the overall stability of the photovoltaic module.

[0054] In the specific implementation process, a number of driven gears 43 mesh in sequence. As the transmission gear 40 rotates, the driven gears 43 can rotate synchronously with the transmission gear 40 to ensure the cleaning effect of the photovoltaic module.

[0055] In the specific implementation process, positioning grooves 57 are uniformly machined on the outer wall of the positioning wheel 51. By the engagement of the machined positioning grooves 57 with the positioning block 54, the winding shaft 50 can be stably limited, ensuring the tension of the protective cloth and thus ensuring the protection effect of the photovoltaic module.

[0056] In the specific implementation process, the conversion box 13 is installed on the upper end of the base plate 22 through the frame. The frame can achieve stable installation of the conversion box 13 and ensure the overall installation stability of the conversion box 13.

[0057] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
