Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, and in particular to a photovoltaic panel with a multi-folded extension structure. Background Technology

[0002] With the increasing global demand for renewable energy, solar energy, as a clean and renewable energy source, has received widespread attention for its development and application. Photovoltaic panels, as the core component of solar power systems, directly impact the cost-effectiveness and widespread adoption of solar power generation through improvements in their performance and efficiency. Traditional photovoltaic panel designs are mostly fixed or have only limited adjustable angles, which to some extent restricts solar energy absorption efficiency, especially under different seasons, time periods, and complex terrain conditions. Therefore, photovoltaic panels with various functions have emerged.

[0003] Most existing folding photovoltaic panels are stacked into one or more panels. However, this folding method still exposes the photovoltaic panels to the external environment, making them susceptible to damage from debris or severe weather. It is difficult to completely protect the photovoltaic panels. In addition, during the photovoltaic power generation process, the angle of the photovoltaic panels needs to be repeatedly adjusted to ensure the photovoltaic power generation effect, making the overall operation inconvenient.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a photovoltaic panel with a multi-foldable extension structure. The photovoltaic panel is stored and extended by a control mechanism, so that the photovoltaic panel can be completely stored inside the box or fully unfolded and laid flat on the surface of the box. The box is rotated 360° to cover the photovoltaic panel by a light source sensor, a first motor and a second motor, thereby ensuring that the photovoltaic panel is always at the optimal illumination angle, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic panel with a multi-folded extension structure, comprising a box body, two cover plates symmetrically and rotatably connected to the inner sides of the box body, an adjustment mechanism installed between the box body and the cover plates, and a fixing block fixed at the bottom of the box body, a telescopic sleeve slidably sleeved on the outer layer of the fixing block, a support column provided at the bottom of the telescopic sleeve, a support base rotatably connected to the bottom of the support column, a reducer fixed inside the support base, a second motor fixed on one side of the reducer, and the output end of the reducer fixed to the bottom of the support base.

[0007] Furthermore, the control mechanism includes a third rotating shaft rotatably connected to the inside of the housing. Two second lead screws are symmetrically sleeved on the outer layers of both sides of the third rotating shaft. The threads of the two second lead screws have opposite structures, and a first threaded sleeve is sleeved on the outer layer of the second lead screw. A first connecting rod is rotatably connected to the top of the first threaded sleeve. The tops of the two first connecting rods are rotatably connected to a third photovoltaic panel. Two light source sensors are symmetrically fixed at the front and rear ends of the upper surface of the third photovoltaic panel, and two connecting pieces are symmetrically fixed at the front and rear ends of the third photovoltaic panel. Two electrical plugs are fixed on the upper surface of the connecting pieces.

[0008] Furthermore, a worm gear is sleeved at the center of the outer layer of the third rotating shaft, and a worm wheel is meshed above the worm gear. A second rotating shaft, rotatably connected to the inside of the housing, passes through the worm wheel. Two rotating disks are symmetrically sleeved on the outer layers of the front and rear ends of the second rotating shaft.

[0009] Furthermore, two connecting blocks are symmetrically fixed on both sides of the rotating disk. A third connecting rod is rotatably connected to one side of the connecting block, a fourth connecting rod is rotatably connected to one side of the third connecting rod, and a second connecting rod is rotatably connected to the upper surface of the third connecting rod. A curved rod is rotatably connected to the top of the fourth connecting rod, and a second photovoltaic panel is rotatably connected to the top of the two second connecting rods and the curved rod on the same side.

[0010] Furthermore, a knob is fixed to one side of the third rotating shaft, extending through and to the outside of the housing, and a main synchronous pulley is sleeved on the outer layer of one side of the third rotating shaft. A first synchronous pulley and a second synchronous pulley are respectively provided on both sides of the main synchronous pulley and rotatably connected to the inside of the housing. The main synchronous pulley and the first synchronous pulley are rotatably connected by a first synchronous belt, which has an X-shaped structure. The main synchronous pulley and the second synchronous pulley are rotatably connected by a second synchronous belt.

[0011] Furthermore, a first rotating shaft is fixed to one side of both the first and second synchronous pulleys and is rotatably connected to the inside of the housing. A connecting sleeve is sleeved on the outer layer of the first rotating shaft, and the outer layer of the connecting sleeve is fixed to one side of the cover plate.

[0012] Furthermore, two second bevel gears are sleeved on the outer layer of the third rotating shaft at the position corresponding to the fixed block. A first bevel gear rotatably connected to the inside of the housing is meshed below the second bevel gear. A first lead screw is fixed below the first bevel gear, penetrating and extending into the inside of the fixed block.

[0013] Furthermore, a second threaded sleeve is fitted onto the outer layer of the first lead screw, one side of which is fixedly connected to the inside of the telescopic sleeve, and a through groove is provided inside the first lead screw corresponding to the connection between the second threaded sleeve and the telescopic sleeve.

[0014] Furthermore, the support column is internally rotatably connected to two gears, one of which has a first motor fixed to its bottom, and the other gear extends through and to the outside of the first motor and is fixed to the bottom of the telescopic sleeve.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In this invention, the three photovoltaic panels are controlled by a regulating mechanism. During normal placement, the three photovoltaic panels are folded inside the box to protect them and reduce the space occupied, thus reducing the damage that may occur during normal placement. During use, the regulating mechanism controls the three photovoltaic panels to extend and lay flat on the surface of the box without stacking, maximizing their area to receive sunlight and thereby improving the overall efficiency of photovoltaic power generation.

[0017] 2. In this invention, while the photovoltaic panel is controlled by the control mechanism, the telescopic sleeve is raised and lowered, thereby increasing the overall height of the photovoltaic panel during operation and avoiding shading, which would reduce the overall efficiency of photovoltaic power generation. After all the photovoltaic panels are laid flat on the upper surface of the box, the electrical terminals and electrical sockets of the second and third photovoltaic panels are engaged, thereby turning on the light source sensor to work, thus ensuring that the photovoltaic panel is at the optimal angle to receive sunlight.

[0018] 3. In the process of photovoltaic power generation, the photovoltaic panel is kept at the optimal angle by a light source sensor. When the light source shifts due to the movement of the sun, the light source sensor transmits a signal to the first motor and the second motor. The second motor drives the support column to rotate, and the first motor drives the telescopic sleeve to deflect. The two work together to make the box rotate 360°, so that when the sun moves to different positions, the photovoltaic panel can be adjusted to the optimal receiving angle.

[0019] In summary, this invention relies on a control mechanism to fold and unfold the photovoltaic panel, facilitating daily storage and preventing potential damage. It also improves the overall photovoltaic power generation efficiency during use. Combined with a telescopic sleeve for lifting, the height of the photovoltaic panel is increased, ensuring it is not obstructed and thus maintaining overall efficiency. Furthermore, a light source sensor, along with the first and second motors, works together to adjust the angle of the photovoltaic panel, ensuring it is at the optimal receiving angle.

[0029] 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

[0030] This embodiment addresses the problem that most existing anti-theft transformers are fixed and sealed inside a protective box to achieve the anti-theft effect. However, the process of fixing and disassembling the anti-theft transformer requires excessive manual intervention, making it difficult to achieve a self-locking effect that is formed as soon as the transformer is placed in the box, which is quite inconvenient overall.

[0031] like Figure 1-6 As shown, a photovoltaic panel with a multi-folded extension structure includes a housing 1. Two cover plates 6 are symmetrically rotatably connected to the two sides of the interior of the housing 1. An adjustment mechanism 5 is installed between the housing 1 and the cover plates 6. The adjustment mechanism 5 includes a third rotating shaft 32 rotatably connected to the interior of the housing 1. Two second lead screws 31 are symmetrically sleeved on the outer layers of the two sides of the third rotating shaft 32. The threads of the two second lead screws 31 are opposite in structure. The opposite threads drive two first threaded sleeves 24 to move relative to each other or in opposite directions. The outer layers of the second lead screws 31 are sleeved with first threaded sleeves 24. The top of the first threaded sleeves 24 is rotatably connected to a first connecting rod 13. The tops of the two first connecting rods 13 are rotatably connected to a third photovoltaic panel 10. Two light source sensors 8 are symmetrically fixed at the front and rear ends of the upper surface of the third photovoltaic panel 10. The light source sensors 8 are electrically connected to a second motor 40 and a first motor 38. Two connecting pieces 41 are symmetrically fixed at the front and rear ends of the third photovoltaic panel 10. Two electrical plugs 42 are fixed on the upper surface of the connecting pieces 41.

[0032] A worm gear 20 is sleeved at the outer center of the third rotating shaft 32. A worm wheel 30 is meshed above the worm gear 20. A second rotating shaft 29, rotatably connected to the inside of the housing 1, runs through the inside of the worm wheel 30. Two rotating disks 16 are symmetrically sleeved on the outer layers of the front and rear ends of the second rotating shaft 29. Two connecting blocks 17 are symmetrically fixed on both sides of the rotating disks 16. A third connecting rod 18 is rotatably connected to one side of the connecting block 17. A fourth connecting rod 19 is rotatably connected to one side of the third connecting rod 18. A second connecting rod 14 is rotatably connected to the upper surface of the third connecting rod 18. A curved rod 15 is rotatably connected to the top of the fourth connecting rod 19. The tops of the two second connecting rods 14 and the curved rod 15 on the same side are rotatably connected to the second photovoltaic panel 9. The second photovoltaic panel 9 is lifted and moved horizontally by the swing of the second connecting rod 14 and the curved rod 15, thereby moving out of the housing 1 and laying flat on both sides of the housing 1.

[0033] A knob 26 is fixed to one side of the third rotating shaft 32, extending to the outside of the housing 1. A main synchronous pulley 25 is sleeved on the outer layer of one side of the third rotating shaft 32. A first synchronous pulley 22 and a second synchronous pulley 28 are respectively provided on both sides of the main synchronous pulley 25 and are rotatably connected inside the housing 1. The main synchronous pulley 25 and the first synchronous pulley 22 are rotatably connected by a first synchronous belt 23. The first synchronous belt 23 has an X structure. When the main synchronous pulley 25 rotates, it drives the first synchronous pulley 22 to rotate in the opposite direction to the main synchronous pulley 25. The main synchronous pulley 25 and the second synchronous pulley 28 are rotatably connected by a second synchronous belt 27. When the second synchronous belt 27 is in a normal connection state, it drives the second synchronous pulley 28 to rotate in the same direction as the main synchronous pulley 25. A first rotating shaft 11 is fixed to one side of both the first synchronous pulley 22 and the second synchronous pulley 28 and is rotatably connected inside the housing 1. A connecting sleeve 12 is sleeved on the outer layer of the first rotating shaft 11. The outer layer of the connecting sleeve 12 is fixed to one side of the cover plate 6.

[0034] When photovoltaic power generation is needed using photovoltaic panels, the third rotating shaft 32 is rotated by turning the knob 26. During the rotation of the third rotating shaft 32, the worm gear 20 and worm wheel 30 drive the second rotating shaft 29 to rotate. During the rotation of the second rotating shaft 29, the rotating disk 16 and connecting block 17 pull the third connecting rods 18 on both sides to move towards the middle. During the movement of the third connecting rods 18, the fourth connecting rod 19 is pulled to swing. The swing of the fourth connecting rod 19 causes the curved rod 15 to deflect. At the same time, during the movement of the third connecting rod 18, the second connecting rod 14 is driven to swing. Then, through the swing of the second connecting rod 14 and the curved rod 15, the two second photovoltaic panels 9 are lifted and moved horizontally. At the same time, the rotation of the third rotating shaft 32 drives the second lead screw 31 to rotate. The rotation of the second lead screw 31 drives the two first screw sleeves 24 to move towards the middle position. As the first screw sleeves 24 move, the third photovoltaic panel 10 is lifted by the swing of the first screw sleeves 24, thus moving out of the box 1 and forming a synchronous flat extension with the second photovoltaic panel 9.

[0035] As the knob 26 rotates, it drives the main synchronous pulley 25 to rotate. The rotation of the main synchronous pulley 25 drives the first synchronous pulley 22 and the second synchronous pulley 28 to rotate through the first synchronous belt 23 and the second synchronous belt 27, respectively. The rotation of the first synchronous pulley 22 and the second synchronous pulley 28 drives the two connecting sleeve rods 12 to rotate. The rotation of the connecting sleeve rods 12 drives the cover plate 6 to flip up. After the cover plate 6 flips up to the side, the first photovoltaic panel 7 inside it forms a flat and unfolded state. At this time, the first photovoltaic panel 7, the second photovoltaic panel 9 and the third photovoltaic panel 10 form an unfolded state, achieving the best light reception state. Example

[0036] This embodiment addresses the problem in the prior art where, when anti-theft transformers need maintenance, personnel must enter the enclosure, which is often quite cramped and inconvenient for maintenance.

[0037] like Figure 7 As shown, the embodiment is a photovoltaic panel with a multi-folded extension structure. There are two second bevel gears 36 sleeved on the outer layer of the third rotating shaft 32 corresponding to the position of the fixing block 35. The lower part of the second bevel gear 36 meshes with a first bevel gear 33 rotatably connected to the inside of the housing 1. The lower part of the first bevel gear 33 is fixed with a first lead screw 21 that passes through and extends into the inside of the fixing block 35. The outer layer of the first lead screw 21 is sleeved with a second threaded sleeve 34. One side of the second threaded sleeve 34 is fixedly connected to the inside of the telescopic sleeve 2. The rotation of the first lead screw 21 drives the second threaded sleeve 34 to rise and fall. The rise and fall of the second threaded sleeve 34 drives the telescopic sleeve 2 to rise and fall, thereby forming the housing 1 to achieve the effect of rising. The inside of the first lead screw 21 is provided with a through groove corresponding to the connection between the second threaded sleeve 34 and the telescopic sleeve 2.

[0038] During the rotation of the third rotating shaft 32, it works in conjunction with the second bevel gear 36 and the first bevel gear 33 to drive the first lead screw 21 to rotate. The rotation of the first lead screw 21 drives the second screw sleeve 34 to rise and fall. The rise and fall of the second screw sleeve 34 drives the telescopic sleeve 2 to rise and fall, thereby forming the box 1 to achieve the effect of rising, avoiding shading during the process of receiving sunlight, and ensuring that the overall working efficiency is not affected when photovoltaic power generation is carried out. Example

[0039] This embodiment addresses the problem in the prior art where it is difficult to quickly remove the anti-theft transformer in the event of an emergency, leading to serious consequences.

[0040] like Figure 8 As shown, the embodiment is a photovoltaic panel with a multi-folded extension structure. A fixing block 35 is fixed to the bottom of the housing 1. A telescopic sleeve 2 is slidably sleeved on the outer layer of the fixing block 35. A support column 3 is provided at the bottom of the telescopic sleeve 2. The opposite surfaces of the telescopic sleeve 2 and the support column 3 are at an angle. Therefore, when the telescopic sleeve 2 rotates, it will deflect, thereby achieving a 360° coverage effect in conjunction with the rotation of the support column 3. A support base 4 is rotatably connected to the bottom of the support column 3. A reducer 39 is fixed inside the support base 4. A second motor 40 is fixed to one side of the reducer 39, and the output end of the reducer 39 is fixed to the bottom of the support base 4. Two gears 37 are rotatably connected inside the support column 3. A first motor 38 is fixed to the bottom of one gear 37, and the top of the other gear 37 passes through and extends to the outside of the first motor 38 and is fixed to the bottom of the telescopic sleeve 2.

[0041] When the housing 1 is opened and extended, the fixed slot at the bottom of the second photovoltaic panel 9 engages with the electrical terminals at the front and rear ends of the third photovoltaic panel 10, thereby activating the light source sensor 8. The light source sensor 8 controls the operation of the first motor 38 and the second motor 40. When sunlight is deflected, the second motor 40 starts and drives the output end of the reducer 39 to rotate. This drives the telescopic sleeve 2 to rotate through the support column 3, which in turn drives the housing 1 to rotate. At the same time, the rotation of the first motor 38, in conjunction with the two gears 37, drives the telescopic sleeve 2 to rotate. Because the opposite surfaces of the telescopic sleeve 2 and the support column 3 are designed with an angle, the telescopic sleeve 2 will deflect when it rotates, thus creating a 360° rotation effect. This allows for the reception of light from different angles, achieving the best reception effect.

[0042] The working process and principle of this invention:

[0043] Step 1: When photovoltaic power generation is needed using photovoltaic panels, the third rotating shaft 32 is rotated by turning the knob 26. During the rotation of the third rotating shaft 32, the worm gear 20 and worm wheel 30 drive the second rotating shaft 29 to rotate. During the rotation of the second rotating shaft 29, the rotating disk 16 and connecting block 17 pull the third connecting rods 18 on both sides to move towards the middle. During the movement of the third connecting rods 18, the fourth connecting rod 19 is pulled to swing. The swing of the fourth connecting rod 19 causes the curved rod 15 to deflect. At the same time, during the movement of the third connecting rod 18, the second connecting rod 14 is driven to swing. Then, through the swing of the second connecting rod 14 and the curved rod 15, the two second photovoltaic panels 9 are lifted and moved horizontally. At the same time, the rotation of the third rotating shaft 32 drives the second lead screw 31 to rotate. The rotation of the second lead screw 31 drives the two first screw sleeves 24 to move towards the middle position. As the first screw sleeves 24 move, the third photovoltaic panel 10 is lifted by the swing of the first screw sleeves 24, thus moving out of the box 1 and forming a synchronous flat extension with the second photovoltaic panel 9.

[0044] As the knob 26 rotates, it drives the main synchronous pulley 25 to rotate. The rotation of the main synchronous pulley 25 drives the first synchronous pulley 22 and the second synchronous pulley 28 to rotate via the first synchronous belt 23 and the second synchronous belt 27, respectively. The rotation of the first synchronous pulley 22 and the second synchronous pulley 28 drives the two connecting sleeve rods 12 to rotate. The rotation of the connecting sleeve rods 12 drives the cover plate 6 to flip up. After the cover plate 6 flips up to the side, the first photovoltaic panel 7 inside it forms a flat and unfolded state. At this time, the first photovoltaic panel 7, the second photovoltaic panel 9 and the third photovoltaic panel 10 are in an unfolded state, achieving the best light reception state.

[0045] Step 2: During the rotation of the third rotating shaft 32, the second bevel gear 36 and the first bevel gear 33 simultaneously drive the first lead screw 21 to rotate. The rotation of the first lead screw 21 drives the second screw sleeve 34 to rise and fall. The rise and fall of the second screw sleeve 34 drives the telescopic sleeve 2 to rise and fall, thereby forming the box 1 to achieve the effect of rising, avoiding shading during the process of receiving sunlight, and ensuring that the overall working efficiency is not affected when photovoltaic power generation is carried out.

[0046] Step 3: When the housing 1 is opened and extended, the fixed slot at the bottom of the second photovoltaic panel 9 engages with the electrical terminals at the front and rear ends of the third photovoltaic panel 10, thereby activating the light source sensor 8. The light source sensor 8 controls the operation of the first motor 38 and the second motor 40. When sunlight is deflected, the second motor 40 starts and drives the output end of the reducer 39 to rotate. This drives the telescopic sleeve 2 to rotate through the support column 3, which in turn drives the housing 1 to rotate. At the same time, the rotation of the first motor 38, in conjunction with the two gears 37, drives the telescopic sleeve 2 to rotate. Because the opposite surfaces of the telescopic sleeve 2 and the support column 3 are designed with an inclined plane, the telescopic sleeve 2 will deflect when it rotates, thus forming a 360° rotation effect. This allows for the reception of light from different angles, achieving the best reception effect.

[0047] In summary, the control mechanism 5 is used to control the unfolding of the housing 1. When the knob 26 is turned, the control mechanism 5 causes the first photovoltaic panel 7, the second photovoltaic panel 9, and the third photovoltaic panel 10 to rise sequentially and be laid flat on the upper surface of the housing 1, thereby forming a larger area of ​​light reception and improving the overall photovoltaic power generation efficiency. At the same time, the light source sensor 8 monitors the light angle, and the second motor 40 and the first motor 38 drive the housing 1 to deflect, thereby keeping the first photovoltaic panel 7, the second photovoltaic panel 9, and the third photovoltaic panel 10 at the optimal light reception angle. Finally, the control mechanism 5 drives the housing 1 to rise, avoiding the housing 1 being blocked as a whole, thus ensuring that the photovoltaic power generation efficiency is not affected as much as possible.

[0048] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
