Description

Technical Field

[0001] This invention relates to a photovoltaic panel support, specifically an adjustable photovoltaic panel anti-tipping support, belonging to the field of photovoltaic support technology. Background Technology

[0002] Photovoltaic panel brackets, also known as solar photovoltaic (PV) brackets, are special supports used to place, install, and fix solar panels in a solar photovoltaic (PV) power generation system. These brackets are primarily made of materials such as aluminum alloy, carbon steel, and stainless steel; they serve to support the solar panels, optimize the solar absorption angle, and facilitate installation and maintenance. PV panel brackets play a crucial role in solar PV power generation systems, affecting not only the system's stability, efficiency, and lifespan, but also directly impacting the overall economic benefits.

[0003] Anti-tipping is one of the important functions of photovoltaic brackets. Since photovoltaic brackets are usually installed in flat and open outdoor areas, they are prone to tipping over or collapsing when faced with severe weather such as strong winds and blizzards.

[0004] A Chinese patent titled "A High-Strength Anti-Tipping Solar Photovoltaic Support" (patent number ZL202210051857.0) discloses a photovoltaic support technology. Under wind force, a carbon dioxide aqueous solution released from the sphere shakes, causing carbon dioxide gas to overflow into an expansion bladder. This expansion compresses and bends a flexible heat-conducting plate, which, through heat conduction, causes a memory torsion spring to twist, driving the movable cylinder to deflect. This, in turn, causes the movable sphere to move downwards under gravity, causing the magnetic shielding membrane to contract, eliminating the magnetic shielding of the magnets, and repelling the magnetic plate. This propels the support rod to contact the ground, working in conjunction with a gripping floor to provide support. While the system provides a certain degree of stability, some carbon dioxide gas is also injected into the flexible hose, causing it to extend and compress the fixing plate to tightly press against the photovoltaic support body. This, combined with the phase change energy dissipation of the buffer and stress-reducing layer, helps to resist the impact of wind. However, although this support can achieve the support and fixation of the photovoltaic support base and the photovoltaic support body, improving stability and support strength, the overall wind resistance remains unchanged, resulting in the risk of the photovoltaic support collapsing. Furthermore, it cannot effectively prevent snow from accumulating on the photovoltaic panels, leading to the photovoltaic support system being prone to collapse when there is too much snow accumulation. Therefore, an adjustable photovoltaic panel anti-tipping support is proposed. Summary of the Invention

[0028] I. This invention utilizes a lifting and adjusting mechanism in conjunction with a linkage transmission mechanism to drive the entire support frame through a switching drive mechanism. This allows the support frame to be pushed out of the pre-embedded base for unfolding. Then, by rotating the transmission connecting shaft, the inner wheel of the drive sprocket drives the adjusting chain to move. The moving adjusting chain drives the support frame to move, adjusting the overall tilt angle of the support frame. This ensures that the solar panel is positioned at the required solar absorption angle during daily use, and that the support frame can be leveled during windy weather to reduce wind resistance and improve the anti-tipping performance of the photovoltaic support.

This prevents snow accumulation on the photovoltaic panels during snowy weather, thus avoiding increased burden on the photovoltaic panel support. In the event of strong winds or blizzards, a lifting adjustment mechanism, in conjunction with a linkage transmission mechanism and a switching drive mechanism, retracts the entire support frame into the pre-embedded base, level with the ground, further reducing wind resistance and improving the protection of the photovoltaic panels and the photovoltaic support as a whole during severe weather.

The longitudinal angle adjustment mechanism 3 includes four adjustment chains 301, four driven sprockets 302, four driving sprockets 303 and a transmission connecting shaft 304.

[0055] The two ends of the two adjusting chains 301 are symmetrically hinged to the bottom of the support frame 103. The four driven sprockets 302 and the driving sprockets 303 are all fixedly connected to the bottom of the inner wall of the pre-embedded base 101. The inner wall of the adjusting chain 301 is meshed with the outer wall of the inner wheel of the driven sprocket 302 and the driving sprocket 303. The outer wall of the transmission connecting shaft 304 is fixedly connected to the inner wheel of the four driving sprockets 303 respectively.

[0056] The lateral angle adjustment mechanism 4 is used to adjust the tilt angle of the solar panel inside the support frame 103.

[0057] In one embodiment, the lifting adjustment mechanism 2 includes four threaded rods 201, four pre-embedded sleeves 202, four support blocks 203, four turbines 204, and four internally threaded pipes 205.

[0058] Among them, one end of each of the four threaded rods 201 is fixedly connected to the bottom of the two support plate frames 102, and each of the four pre-embedded sleeves 202 is fixedly connected to the bottom of the inner wall of the pre-embedded base 101.

[0059] The rotating turbine 204 drives the internally threaded tube 205 to rotate, and the rotating internally threaded tube 205 drives the threaded rod 201 to move using its threads. The moving threaded rod 201 drives the support plate frame 102 to move upward as a whole. The pre-embedded sleeve 202 is used to provide lifting space for the threaded rod 201.

[0060] In one embodiment, the lateral angle adjustment mechanism 4 includes a first driver 401, two photovoltaic panel racks 402, a drive gear 403, a timing belt 404, and two driven gears 405.

[0061] Two photovoltaic panel racks 402 are rotatably connected to the inner wall of the support frame 103. The first driver 401 is installed in the middle of one side of the support frame 103. One end of the drive gear 403 is rotatably connected to the middle of the inner wall of the support frame 103, and the other end of the drive gear 403 is fixedly connected to the output shaft of the first driver 401. One end of each of the two driven gears 405 is rotatably connected to one side of the inner wall of the support frame 103, and the other end of each driven gear 405 is fixedly connected to the middle of one side of the two photovoltaic panel racks 402. The synchronous belt 404 covers the outer wall of the two driven gears 405 and the drive gear 403, and the inner wall of the synchronous belt 404 meshes with the outer wall of the driven gears 405 and the drive gear 403.

[0062] The output shaft of the first driver 401 drives the drive gear 403 to rotate. The rotating drive gear 403 drives the driven gear 405 to rotate via the synchronous belt 404. The rotating driven gear 405 drives the photovoltaic panel rack 402 to move, so that the moving photovoltaic panel rack 402 can drive the solar panel to move. The photovoltaic panel rack 402 is used to provide installation space for the photovoltaic panel, and space is reserved between the two photovoltaic panel racks 402 and between the photovoltaic panel racks 402 and the support frame 103 to ensure that the photovoltaic panel rack 402 can rotate smoothly.

[0063] In one embodiment, the switching drive mechanism 5 includes a second driver 501, a drive switching box 502, a first gear 503, a second gear 504, a bevel linkage gear 505, an outer ring 506, two electric push rods 507, and a double bevel drive shaft 508.

[0064] The second driver 501 is installed on the bottom of the inner wall of the pre-embedded base 101, the bottom of the drive switching box 502 is fixedly connected to the bottom of the inner wall of the pre-embedded base 101, the first toothed column 503 is located on the inner wall of the drive switching box 502 and is fixedly connected to the output shaft of the second driver 501, the second toothed column 504 is located at the end of the first toothed column 503 away from the second driver 501, the inner wall of the bevel linkage gear 505 is meshed with the outer wall of the first toothed column 503 and the second toothed column 504, and the inner wall of the outer ring 506 is rotatably connected to the outer wall of the bevel linkage gear 505.

[0066] The piston rod of the electric push rod 507 drives the outer ring 506 to move.

The guide rod 82 is used to guide the moving outer ring 506. Then, the output shaft of the second driver 501 drives the second toothed column 504 to rotate via the bevel linkage gear 505. Alternatively, the piston rod of the electric push rod 507 drives the outer ring 506 to move. The moving outer ring 506 causes the bevel linkage gear 505 to separate from the second toothed column 504 and make the bevel linkage gear 505 fit against the bottom of the outer side wall of the double bevel drive shaft 508. Then, the output shaft of the second driver 501 drives the first toothed column 503 to rotate.

The rotating drive sprocket 303 drives the adjusting chain 301 to move, thereby adjusting the overall tilt angle of the support frame 103. The driven sprocket 302 is used to change the direction of movement of the adjusting chain 301.

Between the two second limiting frames 603, the transmission main shaft 601 is connected to the two second driven shafts 605 at one end by bevel gear meshing. The two second driven shafts 605 are connected to the two first driven shafts 604 by bevel gear meshing. Several connecting pipes 606 are fixedly connected between the support block 203, the second limiting frame 603, and the first limiting frame 602 in pairs. Four worm gears 607 are fixedly connected to the outer side walls of the two first driven shafts 604 respectively. The outer side walls of the four worm gears 607 are meshed with the outer side walls of the four turbines 204 respectively.

[0072] The rotating second gear 504 drives the transmission main shaft 601 to rotate. The rotating transmission main shaft 601 uses a bevel gear to cooperate with the second driven shaft 605 to drive the first driven shaft 604 to rotate. The rotating first driven shaft 604 uses a worm gear 607 to drive the turbine 204 to rotate.

[0073] In one embodiment, the tensioning mechanism 7 includes four upper supports 701, four lower supports 702, a limiting part 703, eight connecting blocks 704, eight connecting plates 705, eight tensioning sprockets 706, and eight torsion springs 707.

[0074] Among them, one end of each of the four upper brackets 701 is hinged to one end of each of the four lower brackets 702, and the other end of each of the four upper brackets 701 is hinged to the bottom of each of the two support plate frames 102. The other end of each of the four lower brackets 702 is hinged to the bottom of the inner side wall of the pre-embedded base 101. The limiting part 703 is provided on one side of each of the four lower brackets 702. Eight connecting blocks 704 are fixedly connected to one side of each of the four lower brackets 702. Eight connecting plates 705 are rotatably connected to one side of each of the eight connecting blocks 704. Eight tension sprockets 706 are rotatably connected to one side of each of the eight connecting plates 705. Eight torsion springs 707 are fixedly connected between the inner side wall of each of the eight connecting blocks 704 and the eight connecting plates 705. The outer side wall of each of the eight tension sprockets 706 is meshed with one side of each of the four adjusting chains 301.

[0075] The moving adjusting chain 301 drives the tension sprocket 706 to move, which in turn drives the connecting plate 705 to move. The moving connecting plate 705 then drives the torsion spring 707 to twist, so that the rotating torsion spring 707, in conjunction with the connecting plate 705, drives the tension sprocket 706 to provide thrust to one side of the adjusting chain 301. This ensures that the adjusting chain 301 is always in a taut state. At the same time as the adjusting chain 301 returns to its original position with the support plate frame 102, the lower bracket 702, in conjunction with the connecting plate 705 and the tension sprocket 706, can tighten the adjusting chain 301.

[0076] In one embodiment, a water-passing frame 81 is fixedly connected to the middle of the inner wall of the pre-embedded base 101, and a sealing cover plate 86 is installed on the top of the inner wall of the pre-embedded base 101; two external connecting frames 83 are provided on the non-adjacent side of the two support plate frames 102, and the middle of one side of the two external connecting frames 83 is fixedly connected to the support frame 103 through a rotating shaft; a cross connecting part 84 is provided at the end of the two second driven shafts 605 away from the first limiting frame 602; a threaded sleeve 85 is threadedly connected to the outer wall of the two second driven shafts 605; and a cross external connecting plate 87 is slidably connected to the inner wall of the external connecting frame 83.

[0077] The pre-embedded base 101 is sealed by the sealing cover plate 86 to prevent rainwater from entering the interior of the pre-embedded base 101 and causing corrosion to the second actuator 501. The water drain rack 81 is used to drain the water from the inside of the pre-embedded base 101.

[0078] In one embodiment, to improve operational efficiency and reduce the cost of using photovoltaic brackets, a row of driven brackets can be added to both sides of the aforementioned adjustable photovoltaic panel anti-tipping bracket, with the specific effect as follows: Figure 14 and Figure 15As shown, compared with the photovoltaic panel anti-tipping bracket, the row of driven brackets does not have the switching drive mechanism 5, transmission connecting shaft 304, cover 305, and conical transmission gear 306. The rest of the structure is the same. The specific installation method is as follows: insert the cross outer connecting plate 87 between the two outer connecting frames 83 and fix it so that the moving support frame 103 can drive the support frame 103 on the row of driven brackets to move synchronously with the outer connecting frame 83 and the cross outer connecting plate 87; connect the cross connecting part 84 between the two by plugging in, and reinforce the two cross connecting parts 84 with the threaded sleeve 85 so that the second driven shaft 605 in the row of driven brackets can rotate synchronously with the cross connecting part 84 so as to synchronously adjust the overall height of the support plate frame 102.

[0079] When the present invention is in operation: First, the pre-embedded base 101 is installed and fixed as a whole by pre-embedding, and the pre-embedded sleeve 202 is inserted into the soil as a whole to enhance the overall stability of the pre-embedded base 101.

[0080] When the solar panel is installed and ready for use, the piston rod of the electric push rod 507 drives the outer ring 506 to move. The moving outer ring 506 causes the bevel linkage gear 505 to separate from the double bevel drive shaft 508 and slide between the first gear 503 and the second gear 504. The guide rod 82 guides the moving outer ring 506. Then, the output shaft of the second driver 501 drives the second gear 504 to rotate via the bevel linkage gear 505. The rotating second gear... 504 drives the transmission main shaft 601 to rotate. The rotating transmission main shaft 601 uses a bevel gear to cooperate with the second driven shaft 605 to drive the first driven shaft 604 to rotate. The rotating first driven shaft 604 uses a worm gear 607 to drive the turbine 204 to rotate. The rotating turbine 204 drives the internal threaded tube 205 to rotate. The rotating internal threaded tube 205 uses its thread to drive the threaded rod 201 to move. The moving threaded rod 201 drives the support plate frame 102 to move upward as a whole, so that the support plate frame 102 can be unfolded as a whole for use.

[0081] When the support plate frame 102 moves upward as a whole, the moving support plate frame 102 drives the adjusting chain 301 and the upper bracket 701 to move. The moving support plate frame 102 drives the lower bracket 702 to compensate for the distance between the pre-embedded base 101 and the support plate frame 102, and drives the connecting block 704 to move. The moving adjusting chain 301 drives the tension sprocket 706 to move. The moving tension sprocket 706 drives the connecting plate 705 to move. The moving connecting plate 705 drives the torsion spring 707 to twist, so that the torsion spring 707, together with the connecting plate 705, drives the tension sprocket 706 to provide thrust to one side of the adjusting chain 301, ensuring that the adjusting chain 301 is always in a taut state. The limiting part 703 is used to limit the movement between the upper bracket 701 and the lower bracket 702 to prevent the upper bracket 701 and the lower bracket 702 from moving in opposite directions when the support plate frame 102 is reset.

[0082] After the support frame 102 is fully deployed, when it is necessary to adjust the angle of the support frame 103 and the solar panel, the piston rod of the electric push rod 507 drives the outer ring 506 to move. The moving outer ring 506 drives the conical linkage gear 505 to separate from the second gear column 504, and makes the conical linkage gear 505 fit against the bottom of the outer wall of the double conical drive shaft 508. Then, the output shaft of the second driver 501 drives the first gear column 503 to rotate. The rotating first gear column 503 utilizes the conical linkage gear 505 drives the double cone drive shaft 508 to rotate. The rotating double cone drive shaft 508 drives the transmission connecting shaft 304 to rotate via the bevel transmission gear 306. The rotating transmission connecting shaft 304 drives the inner wheel of the drive sprocket 303 to rotate. The rotating drive sprocket 303 drives the adjusting chain 301 to move. The moving adjusting chain 301 pulls down on one side of the support frame 103 to adjust the overall tilt angle of the support frame 103. The driven sprocket 302 is used to change the direction of movement of the adjusting chain 301.

[0083] When the overall tilt angle of the support frame 103 is adjusted, and the angle of the solar panel needs to be adjusted, the output shaft of the first driver 401 drives the drive gear 403 to rotate. The rotating drive gear 403 drives the driven gear 405 to rotate via the synchronous belt 404. The rotating driven gear 405 drives the photovoltaic panel holder 402 to move, so that the moving photovoltaic panel holder 402 can drive the solar panel to move and adjust its angle. The angle of the photovoltaic panel holder 402 and the solar panel can also be adjusted according to the change of the sun's position, so that the solar panel can follow the sun to improve power generation efficiency. However, with the change of angle, shading may easily occur between the two photovoltaic panel holders 402.

[0084] When facing strong winds, the longitudinal angle adjustment mechanism 3 is driven by the switching drive mechanism 5 to level the entire support frame 103, thereby reducing the wind resistance caused by the photovoltaic bracket and preventing the photovoltaic bracket from tilting or deforming due to excessive wind resistance. When facing snowy weather, after leveling the entire support frame 103, the photovoltaic panel rack 402 is driven by the first driver 401 to keep it perpendicular to the support frame 103, so as to prevent snow from accumulating on the photovoltaic panel rack 402 and the solar panels. When facing strong winds or blizzards... The photovoltaic panel rack 402 is reset by the first driver 401 and kept horizontal with the support frame 103. Then, the longitudinal angle adjustment mechanism 3 is driven by the switching drive mechanism 5 to level and reset the support frame 103. Then, the lifting adjustment mechanism 2 is driven by the switching drive mechanism 5 in conjunction with the linkage transmission mechanism 6. The moving lifting adjustment mechanism 2 drives the support rack 102 to retract into the pre-embedded base 101, so that the whole bracket is relatively flush with the ground, which further reduces wind resistance and improves the overall pressure bearing performance of the photovoltaic bracket.

[0085] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
