Description

Technical Field

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

[0002] Solar cells, also known as "solar chips" or "photovoltaic cells," are semiconductor devices that directly convert sunlight into electrical energy. The core principle is the photovoltaic effect—when sunlight shines on a photovoltaic cell made of semiconductor materials (mostly silicon), photon energy excites electrons to transition, forming an electric current. This current is then collected through wires and converted into usable alternating current by an inverter. A single solar cell cannot be used directly as a power source. To use it as a power source, several individual solar cells must be connected in series and parallel and tightly packaged into a module. It is the core and most important part of a solar power generation system and is widely used in distributed household power generation, large-scale ground-mounted photovoltaic power stations, traffic lights, spacecraft, and other fields.

[0003] When supporting and fixing solar photovoltaic panels, the support frame is usually fixed to the ground with rods. However, the support frame fixed with rods is prone to loosening after long-term use and is not easy to move, which affects the long-term use effect. Therefore, we have proposed a tilt-proof solar photovoltaic panel. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an anti-tipping solar photovoltaic panel, including a concave base frame. A fixed long rod is fixedly connected to the inner side of the concave base frame. A side-expanding round rod is sleeved and fixedly connected to the outer side of the fixed long rod. A guide groove is opened on the outer side of the side-expanding round rod. A center of gravity adjustment device is sleeved and slidably connected to the outer side of the side-expanding round rod. A fixed long rod is fixedly connected to the end of the side-expanding round rod away from the fixed long rod. Both ends of the fixed long rod are fixedly connected to side-connecting square plates. A top plate is fixedly connected to the outer side of the fixed long rod. A frame-type fixing plate is fixedly connected to the top of the top plate. A photovoltaic panel body is fixedly connected to one side of the frame-type fixing plate.

[0005] The center of gravity adjustment device includes an annular frame plate, with a coding mechanism fixedly connected to both sides of the annular frame plate. A threaded torsion bar is threaded through and threaded to the outer side of the annular frame plate. The threaded torsion bar, passing through the annular frame plate and threadedly engaged with it, adjusts the electric roller to maintain tight contact with the side-spreading round rod at all times. This prevents the electric roller from loosening after prolonged use and making it difficult to maintain tight contact with the side-spreading round rod, thus affecting the driving effect. One end of the threaded torsion bar is rotatably connected to the electric roller via a rotating bolt. The electric roller drives the annular frame plate to move the coding mechanism, thereby changing the center of gravity position of the side-spreading round rod to adapt to changes in wind direction. This prevents the support frame for fixing the rod from loosening after prolonged use and becoming difficult to move, thus affecting the long-term performance.

[0006] Two side-expanding round rods are provided, and the two side-expanding round rods are symmetrically distributed on the fixed long rod. Multiple guide long grooves are provided, and the multiple guide long grooves are distributed on the side-expanding round rods. Multiple threaded torsion bars are provided, and the multiple threaded torsion bars are distributed on the annular frame plate.

[0007] The inner wall of the guide groove is slidably connected to the inner side of the center of gravity adjustment device, and one side of the side connecting square plate is fixedly connected to one side of the concave base frame.

[0008] A cleaning mechanism is fixedly connected to the side of the adjusting mechanism away from the annular frame plate. A limit rod is fixedly connected to the inner side of the annular frame plate. By setting four limit rods on the inner side of the annular frame plate to abut against the inner wall of the guide groove, the annular frame plate as a whole will not shift. This prevents the electric roller from becoming loose and shifting, which is difficult to detect in time and causes the annular frame plate to shift as a whole, affecting the driving effect. By inserting the limit rods into the guide groove, the annular frame plate is rotated and limited. This prevents the annular frame plate from rotating due to external force when the electric roller becomes loose, which would cause the electric roller to deflect and make it difficult to move along the direction of the guide groove.

[0009] The cleaning mechanism is sleeved on the side-expanding round rod and slidably connected to the side-expanding round rod; the inner side of the cleaning mechanism is slidably connected to the inner wall of the guide groove.

[0010] The end of the limiting rod away from the annular frame plate is slidably connected to the inner wall of the guide groove. Multiple limiting rods are provided, and the multiple limiting rods are distributed on the inner side of the annular frame plate.

[0011] Furthermore, the adjusting mechanism includes an annular weight with a rounded corner groove on its outer side. A rounded-corner heavy weight is inserted into this groove to increase the weight of the side-extending rod, improving stability and preventing the entire frame from being lifted and overturned in strong winds. The top of the inner wall of the rounded corner groove has an internal circular groove, and a push spring is fixedly connected to the top of this groove. A circular pressure plate is fixedly connected to the bottom of the push spring. The pressure plate, pushed by the spring, presses down on the heavy weight at the bottom, preventing it from sliding out of the groove as the annular frame moves back and forth. The inner wall of the rounded corner groove has an arc-shaped sliding hole, and an arc-shaped slider is slidably connected to the inner wall of this hole. The sliding of the arc-shaped slider pushes out the heavy weight, reducing the weight of the side-extending rod and preventing further damage. When the wind resistance is low, the side-extending round rod loses wind balance and is prone to breakage due to excessive gravity after a long period of time. The outer side of the arc-shaped slider is provided with an arc-shaped through hole, and the inner wall of the arc-shaped through hole is slidably connected to an arc-shaped fixing block. By setting the arc-shaped fixing block between the arc-shaped through holes on the outer side of the annular weight, the arc-shaped slider is slidably limited to prevent it from sliding out of the arc-shaped sliding hole when the annular weight moves back and forth, thus affecting its use. One side of the annular weight is fixedly connected to one side of the annular frame plate. Multiple rounded corner through grooves are provided, and multiple rounded corner through grooves are distributed on the outer side of the annular weight. The outer side of the circular pressure plate is slidably connected to the inner wall of the built-in circular groove. Multiple arc-shaped sliding holes are provided, and multiple arc-shaped sliding holes are distributed on the inner wall of the rounded corner through grooves and extend to the outer side of the annular weight. One side of the arc-shaped fixing block is fixedly connected to the outer side of the annular weight.

[0012] Furthermore, the cleaning mechanism includes a conical ring plate. When the conical ring plate moves, it scrapes and cleans the outer surface of the side-expanding round rod, preventing dust and debris carried by the wind from adhering to the surface of the side-expanding round rod and affecting the driving effect of the electric roller. An internal inclined block is fixedly connected to the inner wall of the conical ring plate. As the conical ring plate moves, the internal inclined block is always positioned within the guide groove and scrapes and cleans the inner wall of the guide groove, preventing excessive dust particles from accumulating inside the guide groove after prolonged use and affecting the sliding effect of the limiting rod. A conical ring pad is sleeved and fixedly connected to the outer side of the conical ring plate. By setting the conical ring pad on the outer side of the conical ring plate, it elastically contacts hard stones, reducing impact damage to the conical ring plate and preventing prolonged contact between the conical ring plate and hard stones. After impact contact, the block wears down and gradually becomes unusable. An arc-shaped brush is fixedly connected to the outer side of the conical ring plate. As the conical ring plate moves, the arc-shaped brush cleans the dust particles on the outer surface of the side-extension rod, preventing the dust particles from being difficult to remove when the conical ring plate cleans the outer surface of the side-extension rod, which would cause the dust particles to wear down due to long-term friction contact with the electric roller. The conical ring plate is sleeved on the side-extension rod and slidably connected to it. The outer side of the built-in inclined block is slidably connected to the inner wall of the guide groove. Multiple built-in inclined blocks are provided, and the multiple built-in inclined blocks are distributed at the position where the inner wall of the conical ring plate is aligned with the guide groove. Multiple arc-shaped brushes are provided, and the multiple arc-shaped brushes are distributed on the outer side of the conical ring plate.

[0013] This invention provides an anti-tipping solar photovoltaic panel. It has the following beneficial effects:

[0014] 1. This anti-tipping solar photovoltaic panel uses an electric roller to drive a ring frame plate, which in turn moves a adjusting mechanism to change the center of gravity of the side-mounted round rod to adapt to wind direction changes. This prevents the support frame, which is fixed by the rod, from loosening after prolonged use and becoming difficult to move, thus affecting its long-term performance. Round, rounded heavy weights are inserted into the rounded corner slots to increase the weight of the side-mounted round rod and improve its stability, preventing the entire base frame from being lifted up and tipping over in strong winds. The conical ring plate scrapes and cleans the outer surface of the side-mounted round rod as it moves, preventing the accumulation of mud and debris carried by the wind, which is difficult to remove and affects the driving effect of the electric roller.

[0015] 2. This anti-tipping solar photovoltaic panel is equipped with a center of gravity adjustment device. A threaded torsion bar passes through the annular frame plate and engages with its thread to adjust the electric roller to maintain tight contact with the side-mounted round rod. This prevents the electric roller from loosening after prolonged use, which would affect the driving effect. The electric roller drives the annular frame plate, which in turn moves the adjusting mechanism to change the center of gravity position of the side-mounted round rod to adapt to wind direction changes. This prevents the support frame fixed by the rod from loosening after prolonged use and becoming difficult to move, thus affecting long-term performance. Four limiting rods are set on the inner side of the annular frame plate to abut against the inner wall of the guide groove, ensuring that the annular frame plate does not shift. This prevents the electric roller from shifting and being difficult to detect in time, which would affect the overall driving effect. The limiting rods are inserted into the guide groove to limit the rotation of the annular frame plate, preventing the electric roller from shifting due to external forces when it is loose, which would make it difficult for the electric roller to move along the direction of the guide groove.

[0016] 3. This anti-tipping solar photovoltaic panel is equipped with a weight adjustment mechanism. A rounded-corner heavy weight is inserted into the rounded-corner slot to increase the weight of the side-mounted rod, improving stability and preventing the entire frame from being lifted and tipping over in strong winds. A circular pressure plate, pushed by a spring, constantly presses down on the heavy weight at the bottom, preventing it from sliding out of the rounded-corner slot as the ring frame moves back and forth. An arc-shaped slider pushes the heavy weight out, reducing the weight of the side-mounted rod and preventing breakage due to excessive gravity caused by wind imbalance in low winds. An arc-shaped fixing block between the arc-shaped holes on the outside of the ring weight limits the sliding of the arc-shaped slider, preventing it from sliding out of the arc-shaped holes as the ring weight moves back and forth, thus affecting its use.

[0017] 4. This anti-tipping solar photovoltaic panel is equipped with a cleaning mechanism. When the conical ring plate moves, it scrapes and cleans the outer surface of the side-mounted round rod to prevent the surface of the side-mounted round rod from being covered with mud and dust carried by the wind, which is difficult to remove and affects the driving effect of the electric roller. By setting a conical ring pad on the outside of the conical ring plate, it makes elastic contact with hard stones to reduce impact damage to the conical ring plate and prevents the conical ring plate from being worn and gradually damaged after long-term impact contact with hard stones, making it unusable. The built-in inclined block is always located in the guide groove as the conical ring plate moves and scrapes and cleans the inner wall of the guide groove to prevent excessive accumulation of dust particles in the guide groove after long-term use, which affects the sliding effect of the limit rod. The arc-shaped brush sweeps away dust particles on the outer surface of the side-mounted round rod as the conical ring plate moves, preventing the conical ring plate from being unable to remove dust particles from the outer surface of the side-mounted round rod, which would cause dust particles to rub against the electric roller for a long time and cause wear.

[0027] 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.

[0028] Please see Figures 1-4This invention provides an anti-tipping solar photovoltaic panel, comprising a concave base frame 1, a fixed long rod 2 fixedly connected to the inner side of the concave base frame 1, a side-expanding round rod 3 sleeved and fixedly connected to the outer side of the fixed long rod 2, a guide groove 4 opened on the outer side of the side-expanding round rod 3, a center of gravity adjustment device 5 sleeved and slidably connected to the outer side of the side-expanding round rod 3, a fixed long rod 6 passing through and fixedly connected to the end of the side-expanding round rod 3 away from the fixed long rod 2, side-connecting square plates 7 fixedly connected to both ends of the fixed long rod 6, a top connecting plate 8 fixedly connected to the outer side of the fixed long rod 2, a frame-type fixing plate 9 fixedly connected to the top of the top connecting plate 8, and a photovoltaic panel body 10 fixedly connected to one side of the frame-type fixing plate 9.

[0029] The center of gravity adjustment device 5 includes an annular frame plate 501. Both sides of the annular frame plate 501 are fixedly connected to the adjustment mechanism 502. A threaded torsion bar 503 is threaded through and threaded to the outer side of the annular frame plate 501. One end of the threaded torsion bar 503 is rotatably connected to an electric roller 504 through a rotating bolt.

[0030] There are two side-expanding round rods 3, and the two side-expanding round rods 3 are symmetrically distributed on the fixed long rod 2. There are multiple guide long grooves 4, and the multiple guide long grooves 4 are distributed on the side-expanding round rods 3. There are multiple threaded torsion bars 503, and the multiple threaded torsion bars 503 are distributed on the annular frame plate 501.

[0031] The inner wall of the guide groove 4 is slidably connected to the inner side of the center of gravity adjustment device 5, and one side of the side connecting square plate 7 is fixedly connected to one side of the concave base frame 1.

[0032] A cleaning mechanism 505 is fixedly connected to the side of the adjusting mechanism 502 away from the annular frame plate 501, and a limit rod 506 is fixedly connected to the inner side of the annular frame plate 501.

[0033] The cleaning mechanism 505 is sleeved on the side-expanding round rod 3 and slidably connected to the side-expanding round rod 3. The inner side of the cleaning mechanism 505 is slidably connected to the inner wall of the guide groove 4.

[0034] The end of the limiting rod 506 away from the annular frame plate 501 is slidably connected to the inner wall of the guide groove 4. Multiple limiting rods 506 are provided, and multiple limiting rods 506 are distributed on the inner side of the annular frame plate 501. When in use, when the wind force is large on one side of the concave base frame 1 near the side connecting square plate 7, the position of the center of gravity adjustment device 5 on the side extension round rod 3 is moved towards the windward direction so that the center of gravity is close to the windward side. When the wind force is large on the two sides adjacent to the concave base frame 1 and the side connecting square plate 7, the center of gravity adjustment device 5 is adjusted to the position of the side extension round rod 3 near the bottom to reduce the height of the center of gravity of the frame, so that the frame is not easy to tip over.

[0035] The rotating threaded torsion bar 503 passes through the annular frame plate 501 and, through its threaded engagement, pushes the electric roller 504 into tight contact with the outer surface of the side-extension round rod 3. The threaded torsion bar 503, passing through the annular frame plate 501 and threadedly engaging with it, adjusts the electric roller 504 to maintain constant tight contact with the side-extension round rod 3. At this time, the rolling contact between the electric roller 504 and the side-extension round rod 3 causes the annular frame plate 501 to move. When the annular frame plate 501 moves, it drives the adjusting mechanisms 502 and cleaning mechanisms 505 on both sides to move together. The electric roller 504 drives the annular frame plate 501, which in turn moves the adjusting mechanisms 502, thereby changing the center of gravity position of the side-extension round rod 3 to adapt to changes in wind direction. When 01 moves, it drives the inner limiting rod 506 to move. When the limiting rod 506 moves with the annular frame plate 501, the end of the limiting rod 506 away from the annular frame plate 501 always abuts against the guide groove 4. By setting four limiting rods 506 on the inner side of the annular frame plate 501 and abutting against the inner wall of the guide groove 4, the annular frame plate 501 will not shift as a whole. By inserting the limiting rods 506 into the guide groove 4, the annular frame plate 501 is rotated and limited. At the same time, when the wind force changes, the weight can be adjusted by the adjusting mechanism 502 to improve the overall center of gravity stability of the frame. When the annular frame plate 501 moves, the cleaning mechanism 505 cleans the surface of the side-extension round rod 3.

[0036] Please see Figures 1-8 This invention provides an anti-tipping solar photovoltaic panel: the adjusting mechanism 502 includes an annular weight 5021, a rounded corner through groove 5022 on the outer side of the annular weight 5021, an inner circular groove 5023 on the top of the inner wall of the rounded corner through groove 5022, a push spring 5024 fixedly connected to the top of the inner wall of the inner circular groove 5023, a circular pressure plate 5025 fixedly connected to the bottom of the push spring 5024, an arc-shaped sliding hole 5026 on the inner wall of the rounded corner through groove 5022, an arc-shaped slider 5027 slidably connected to the inner wall of the arc-shaped sliding hole 5026, and an arc-shaped through hole 50 on the outer side of the arc-shaped slider 5027. 28. An arc-shaped fixing block 5029 is slidably connected to the inner wall of the arc-shaped through hole 5028. One side of the annular weight 5021 is fixedly connected to one side of the annular frame plate 501. Multiple rounded corner through grooves 5022 are provided, and multiple rounded corner through grooves 5022 are distributed on the outside of the annular weight 5021. The outer side of the circular pressure plate 5025 is slidably connected to the inner wall of the built-in circular groove 5023. Multiple arc-shaped sliding holes 5026 are provided, and multiple arc-shaped sliding holes 5026 are distributed on the inner wall of the rounded corner through groove 5022 and extend to the outside of the annular weight 5021. One side of the arc-shaped fixing block 5029 is fixedly connected to the outside of the annular weight 5021.

[0037] The cleaning mechanism 505 includes a conical ring plate 5051. An internal inclined block 5052 is fixedly connected to the inner wall of the conical ring plate 5051. A conical ring pad 5053 is sleeved and fixedly connected to the outer side of the conical ring plate 5051. An arc-shaped brush 5054 is fixedly connected to the outer side of the conical ring plate 5051. The conical ring plate 5051 is sleeved on the side-expanding round rod 3 and slidably connected to the side-expanding round rod 3. The outer side of the internal inclined block 5052 is slidably connected to the inner wall of the guide groove 4. Multiple internal inclined blocks 5052 are provided, and these blocks are distributed at positions where the inner wall of the conical ring plate 5051 aligns with the guide groove 4. Multiple arc-shaped brushes 5054 are provided. Multiple arc-shaped brushes 5054 are distributed on the outer side of the conical ring plate 5051. During use, when the wind force increases, a rounded-corner heavy weight is inserted into the rounded-corner through-slot 5022 to increase the weight of the side-extending round rod 3 and improve center of gravity stability. Simultaneously, the push spring 5024 at the top of the inner wall of the built-in round groove 5023 applies pressure to the round pressure plate 5025 through its extension force. The round pressure plate 5025, pushed by the push spring 5024, presses down on the heavy weight at the bottom. When the wind force decreases, an arc-shaped slider 5027 is pushed into the arc-shaped sliding hole 5026. As the arc-shaped slider 5027 moves along the arc-shaped path into the arc-shaped sliding hole 5026, it pushes the rounded-corner through-slot 5022... The heavy weight inside is pushed out by the arc-shaped slider 5027, reducing the weight of the side-extending round rod 3. The arc-shaped slider 5027, which slides into the arc-shaped sliding hole 5026, stops sliding when it comes into contact with the arc-shaped fixing block 5029. The arc-shaped fixing block 5029 is set between the arc-shaped through holes 5028 on the outside of the annular weight 5021 to limit the sliding of the arc-shaped slider 5027. When the annular weight 5021 moves with the annular frame plate 501, it drives the conical ring plate 5051 on one side to move. When the conical ring plate 5051 moves, it scrapes and cleans the outer surface of the side-extending round rod 3. At the same time, hard debris such as stones carried by the wind are blown towards the conical ring plate. When plate 5051 moves, it will first come into elastic contact with the conical ring pad 5053 fitted on the outside of the conical ring plate 5051. By setting the conical ring pad 5053 on the outside of the conical ring plate 5051 to make elastic contact with hard stones, the impact damage to the conical ring plate 5051 is reduced. When the conical ring plate 5051 moves, it drives the built-in inclined block 5052 on the inner wall and the arc-shaped brush 5054 on the outer side to move together. When the conical ring plate 5051 moves, the built-in inclined block 5052 is always located in the guide groove 4 and performs scraping cleaning on the inner wall of the guide groove 4. When the conical ring plate 5051 moves, the arc-shaped brush 5054 cleans the dust particles on the outer surface of the side-extension round rod 3.

[0038] When the wind force is strong on one side of the concave base frame 1 near the side connecting square plate 7, the position of the center of gravity adjustment device 5 on the side extension round rod 3 is moved towards the windward direction so that the center of gravity is close to the windward side. When the wind force is strong on the two sides adjacent to the concave base frame 1 and the side connecting square plate 7, the center of gravity adjustment device 5 is adjusted to the position of the side extension round rod 3 near the bottom to reduce the height of the center of gravity of the frame and make the frame less likely to tip over.

[0039] The rotating threaded torsion bar 503 passes through the annular frame plate 501 and, through its threaded engagement, pushes the electric roller 504 into tight contact with the outer surface of the side-extension round rod 3. The threaded torsion bar 503, passing through the annular frame plate 501 and threadedly engaging with it, adjusts the electric roller 504 to maintain constant tight contact with the side-extension round rod 3. At this time, the rolling contact between the electric roller 504 and the side-extension round rod 3 causes the annular frame plate 501 to move. When the annular frame plate 501 moves, it drives the adjusting mechanisms 502 and cleaning mechanisms 505 on both sides to move together. The electric roller 504 drives the annular frame plate 501, which in turn moves the adjusting mechanisms 502 to change the center of gravity of the side-extension round rod 3 to adapt to wind direction changes. When the annular frame plate 501 moves, it also moves the inner limiting rod 506. As the annular frame plate 501 moves, the end of the positioning rod 506 away from the annular frame plate 501 always abuts against the guide groove 4. By setting four positioning rods 506 on the inner side of the annular frame plate 501 and ensuring their contact with the inner wall of the guide groove 4, the annular frame plate 501 as a whole will not shift. The positioning rods 506 are inserted into the guide groove 4 to limit the rotation of the annular frame plate 501. Simultaneously, when the wind force changes, the weight can be adjusted by the adjusting mechanism 502 to improve the overall stability of the frame. The cleaning mechanism 505 cleans the surface of the side-extension round rod 3 as the annular frame plate 501 moves. When the wind force increases, rounded-corner heavy weights are inserted into the rounded-corner through groove 5022 to increase the weight of the side-extension round rod 3 and improve its stability. The center of gravity is stable. Simultaneously, the push spring 5024 at the top of the inner wall of the built-in circular groove 5023 applies pressure to the circular pressure plate 5025 through its extension force. The circular pressure plate 5025, pushed by the push spring 5024, presses down on the heavy weight at the bottom. When the wind force decreases, the arc-shaped slider 5027 is pushed into the arc-shaped sliding hole 5026. As the arc-shaped slider 5027 moves along the arc-shaped path into the arc-shaped sliding hole 5026, it pushes out the heavy weight in the rounded corner through-slot 5022. The pushing action of the arc-shaped slider 5027 pushes out the heavy weight, reducing the weight of the side-extending circular rod 3. The arc-shaped slider 5027, sliding into the arc-shaped sliding hole 5026, stops sliding when it contacts the arc-shaped fixing block 5029. The arc-shaped through-slot 5022 on the outside of the annular weight block 5021... An arc-shaped fixing block 5029 is set between holes 5028 to limit the sliding of the arc-shaped slider 5027. When the annular weight 5021 moves with the annular frame plate 501, it drives the conical ring plate 5051 on one side to move. When the conical ring plate 5051 moves, it scrapes and cleans the outer surface of the side-spreading round rod 3. At the same time, when hard debris such as stones blown by the wind hits the conical ring plate 5051, it will first come into elastic contact with the conical ring pad 5053 sleeved on the outside of the conical ring plate 5051. By setting the conical ring pad 5053 on the outside of the conical ring plate 5051 to make elastic contact with hard stones, the impact damage to the conical ring plate 5051 is reduced. When the conical ring plate 5051 moves, it drives the built-in inclined block 5052 on the inner wall and the arc-shaped brush 5054 on the outer side to move together.The built-in inclined block 5052, as it moves with the conical ring plate 5051, remains within the guide groove 4 and scrapes the inner wall of the guide groove 4. The arc-shaped brush 5054, as it moves with the conical ring plate 5051, cleans dust particles from the outer surface of the side-extended round rod 3.
