Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, and specifically to a telescopic photovoltaic energy storage integrated device. Background Technology

[0002] The core role of photovoltaic equipment is to support the entire photovoltaic industry chain, including production, construction, operation and maintenance, and testing. Every step, from silicon raw material purification to the stable power generation of photovoltaic power plants, relies on specialized photovoltaic equipment to realize process implementation, efficiency improvement, quality control, and large-scale production, ultimately transforming solar power generation technology into commercially viable and widely applicable products and systems.

[0003] Chinese patent CN219041698U discloses a telescopic photovoltaic energy storage integrated device, which includes an extension mechanism and a photovoltaic rotation mechanism. After use, the electric telescopic rod is activated, causing the moving column to move downward, which causes the L-shaped toothed plate to drive the gear to rotate, causing the drive toothed plate to move upward, thereby lifting the protective plate upward. This allows the protective plate to protect the outside of the photovoltaic panel, making the photovoltaic panel safer when not in use and reducing the probability of the photovoltaic panel being damaged and affecting its use.

[0004] However, the existing technology has the following drawbacks: it can only adjust the angle of two photovoltaic panels at a time, which is not efficient enough. After being stored, the overall size of the device does not change significantly and is still large, resulting in a large space occupation. In addition, it can only protect the photovoltaic panels after they are stored. It cannot protect the photovoltaic panels when they are in use, which poses certain safety hazards. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a telescopic photovoltaic energy storage integrated device.

The folding mechanism includes a drive unit, rods a, and protective boxes; multiple protective boxes are stacked together, and photovoltaic panels are installed in the protective boxes; two sets of rods a are provided, with each set consisting of two rods a; and they are respectively located on both sides of the multiple protective boxes; rods a and multiple protective boxes are rotatably connected together; the bottommost protective box is connected to plate a; the drive unit is located on plate a and connected to rods a. The cleaning mechanism, located at the bottom of the protective box, is used to clean the dust on the surface of the protective box.

[0007] Preferably, the output end of motor a is connected to a gear; the bottom end of the sliding cover is provided with a rack; the rack meshes with the gear.

[0008] Preferably, a wiping cotton block is detachably connected to the bottom of the sliding cover for cleaning the dust from the topmost protective box.

[0009] Preferably, the top of the protective box has an opening, and a transparent plate is detachably connected inside the opening.

[0010] Preferably, the cleaning mechanism includes a motor b, a U-shaped plate, a steering plate, and brush bristles; the U-shaped plate is connected to the bottom of the protective box; the steering block is rotatably located on the inner side of the U-shaped plate; the motor is located on the U-shaped plate and its output end is connected to the steering plate; the brush bristles are evenly distributed on the steering plate.

[0014] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: By incorporating storage and folding mechanisms, the protective boxes can provide some protection for the photovoltaic panels during normal operation. The folding mechanism allows for angle adjustment of multiple photovoltaic panels, and after multiple folds are folded and stored, each layer of the protective box carries the photovoltaic panels in a nearly flat state, significantly reducing the overall size of the device and lowering its space occupancy, thus protecting the photovoltaic panels in severe weather.

[0015] By incorporating a cleaning mechanism that utilizes the staggered arrangement of the protective boxes during folding, the cleaning mechanism can automatically clean dust and impurities from each layer of transparent panels. This prevents dust and impurities from accumulating on the transparent panels and affecting light transmittance, eliminating the need for manual cleaning and reducing maintenance time.

[0018] Example 1, as Figures 1-5 and Figure 7 As shown, the present invention proposes a telescopic photovoltaic energy storage integrated device, which includes a storage mechanism, a folding mechanism and a cleaning mechanism. The storage mechanism includes a box 1, a plate a4, telescopic components 19, a sliding cover 2, and a motor a7. Multiple telescopic components 19 are located inside the box 1. The plate a4 is connected to the telescopic components 19. A slide rail 5 is provided at the top of the box 1. A sliding groove is provided at the bottom of the sliding cover 2, which slides along the slide rail 5. The motor a7 is mounted on the box 1 and connected to the sliding cover 2. A gear 14 is connected to the output end of the motor a7. A rack 15 is provided at the bottom of the sliding cover 2; the rack 15 meshes with the gear 14. A detachable wiping cotton block is attached to the bottom of the sliding cover 2 for cleaning the top protective box 9 (since there is no cleaning mechanism above the top protective box 9, when the sliding cover 2 is closed, the wiping cotton block at its bottom can clean the top protective box 9). Dust and impurities on the surface of the protective box 9 are cleaned; the wiping cotton pad is connected to the sliding cover 2 via Velcro, making it easy to replace the wiping cotton pad; one end of the sliding cover 2 is connected to a caster 3 to support the sliding cover 2 (when the sliding cover 2 reaches its maximum opening degree, the caster 3 can support the end of the sliding cover 2 away from the slide rail 5, ensuring the stability of the sliding cover 2); a functional box 6 is provided on the plate a4, which contains an inverter, a battery pack, and a charger; the battery pack is connected to the inverter and the charger via wires; the inverter is connected to an external circuit via wires; the charger is connected to the photovoltaic panel 11 via wires; so that the electrical energy generated by the photovoltaic panel 11 can be stored in the battery pack; The folding mechanism includes a drive unit, rods a8, and protective boxes 9. Multiple protective boxes 9 are stacked (with a certain spacing between adjacent protective boxes 9 to ensure they are staggered and achieve a flat laying effect). Photovoltaic panels 11 are installed on the protective boxes 9. Two sets of rods a8 are provided, with each set consisting of two rods a8. These are located on both sides of the multiple protective boxes 9. The rods a8 and multiple protective boxes 9 are rotatably connected. The bottommost protective box 9 is connected to plate a4. The drive unit is located on plate a4 and connected to rods a8. An opening is provided at the top of the protective box 9, and a transparent plate 10 is detachably connected inside the opening (the transparent plate 10 is a composite front panel, with a PET layer in the middle and a fluorine-containing coating on the outer layer; its light transmittance decreases slightly with increasing thickness, and it is resistant to UV aging and has good acid resistance). The protective box 9 can protect the photovoltaic panels 11 during normal operation, while the transparent plate 10 allows sunlight to penetrate and illuminate the photovoltaic panels 11. The cleaning mechanism is located at the bottom of the protective box 9 and is used to clean the dust on the surface of the protective box 9.

[0019] In this embodiment, when the photovoltaic panel 11 is in normal use, the drive unit drives the rod a8 to rotate and tilt at a certain angle. During the tilting process, the protective box 9 remains in a horizontal state, thereby keeping the photovoltaic panel 11 inside the protective box 9 in a horizontal state. After the rod a8 tilts, the photovoltaic panels 11 of each layer are staggered, realizing the function of synchronous adjustment of the angle of multiple photovoltaic panels 11; ensuring that sunlight can shine on each layer of photovoltaic panels 11 to ensure photovoltaic power generation efficiency; the protective box 9 can protect the photovoltaic panel 11 when it is in normal use.

[0020] When the photovoltaic panel 11 needs to be folded and stored due to severe weather (such as strong winds, hail, etc.), the drive unit can tilt the rod a8 to its maximum extent, so that the photovoltaic panels 11 in each protective box 9 are in a similar flat state (i.e., each photovoltaic panel 11 is almost on the same horizontal plane), which significantly reduces the volume of the entire device. Then, the telescopic component 19 drives the plate a4 to descend, thereby lowering the entire folding mechanism into the box 1. Finally, the motor a7 is turned on, and the motor a7 drives the gear 14 to rotate. The gear 14 drives the rack 15 to move, so that the sliding covers 2 on both sides move towards each other. During the movement of the sliding covers 2, the wiping cotton at the bottom of the sliding covers can sweep away the dust and impurities on the surface of the top protective box 9. After the sliding covers 2 close together, they can seal and protect the box 1, thereby protecting the photovoltaic panel 11 and ensuring the safety of the photovoltaic panel 11 in harsh environments.

[0021] Example 2, as Figure 6 As shown, the present invention proposes a telescopic photovoltaic energy storage integrated device. Compared with Embodiment 1, this embodiment also details the structure of the cleaning mechanism. The cleaning mechanism includes a motor b12, a U-shaped plate, a steering plate, and brush bristles 13. The U-shaped plate is connected to the bottom end of the protective box 9. The steering block is rotatably located on the inner side of the U-shaped plate. The motor is located on the U-shaped plate and its output end is connected to the steering plate. The brush bristles 13 are evenly distributed on the steering plate.

[0022] In this embodiment, when the photovoltaic panel 11 is in normal use, the motor b12 drives the steering plate and brush 13 to rotate to a horizontal state to prevent the brush 13 from blocking sunlight. Before folding and storing, the rod a8 is in a vertical state. The motor b12 drives the steering plate to rotate, so that the brush 13 rotates to a state perpendicular to the protective box 9. At this time, the brush 13 at the bottom of the upper protective box 9 will contact the transparent plate 10 at the top of the lower protective box 9. Then, the drive unit drives the rod a8 to rotate and tilt so that the protective boxes 9 carrying the photovoltaic panel 11 are staggered and stored. At this time, due to the relative movement between the protective boxes 9, the brush 13 will sweep across the transparent plate 10 at the top of the protective box 9 to clean the dust and impurities on it, realizing the self-cleaning function and preventing the accumulation of dust and impurities on the transparent plate 10 from affecting the light transmittance.

[0023] Example 3, asFigures 1-2 As shown, the present invention proposes a telescopic photovoltaic energy storage integrated device. Compared with Embodiment 2, this embodiment also details the structure of the drive unit. The drive unit includes a motor c20, a synchronous pulley a18, a synchronous pulley b16, and a synchronous toothed belt 17. The synchronous pulley a18 is connected to the rod a8. The motor c20 is mounted on the plate a4 and its output end is connected to the synchronous pulley b16. The synchronous pulley a18 and the synchronous pulley b16 are connected by the synchronous toothed belt 17 (the radius of the synchronous pulley a18 is larger than the radius of the synchronous pulley b16).

[0024] In this embodiment, motor C20 drives synchronous pulley B16 to rotate, which in turn drives synchronous pulley A18 to rotate via synchronous toothed belt 17. Since the radius of synchronous pulley A18 is larger than that of synchronous pulley B16, the transmission ratio is greater than 1. This means that the rotational speed of synchronous pulley A18 is less than that of synchronous pulley B16. At the same time, the driving force required by synchronous pulley B16 to drive synchronous pulley A18 is also reduced, thereby reducing the output power of motor C20. The reduced rotational speed of synchronous pulley A18 allows rod A8 to rotate and tilt slowly, ensuring the stability of photovoltaic panel 11 during angle adjustment.

[0025] In summary, when the photovoltaic panel 11 is in normal use, the motor c20 drives the synchronous pulley b16 to rotate, which in turn drives the synchronous pulley a18 to rotate slowly through the synchronous toothed belt 17. The synchronous pulley a18 drives the rod a8 to rotate and tilt at a certain angle. During the tilting process, the protective box 9 remains in a horizontal state, thus keeping the photovoltaic panel 11 inside the protective box 9 in a horizontal state. After the rod a8 is tilted, the photovoltaic panels 11 of each layer are staggered, realizing the function of synchronous adjustment of the angle of multiple photovoltaic panels 11; ensuring that sunlight can shine on each layer of photovoltaic panels 11 to ensure photovoltaic power generation efficiency; the protective box 9 can protect the photovoltaic panel 11 when it is in normal use.

[0026] When photovoltaic panels 11 need to be folded and stored due to severe weather (such as strong winds or hail), before folding and storing, rod a8 is positioned vertically. Motor b12 drives the steering plate to rotate, causing the brush bristles 13 to rotate perpendicular to the protective box 9. At this point, the brush bristles 13 at the bottom of the upper protective box 9 will contact the transparent plate 10 at the top of the lower protective box 9. Then, motor c20 drives rod a8 to rotate and tilt, allowing the protective boxes 9 carrying photovoltaic panels 11 to be staggered for storage. Due to the relative movement between the protective boxes 9, the brush bristles 13 will sweep across the transparent plate 10 at the top of the protective box 9, cleaning away dust and impurities, achieving a self-cleaning function and preventing dust and impurities from accumulating on the transparent plate 10 and affecting light transmittance. After a8 is tilted to its maximum angle, the protective box 9 carries the photovoltaic panel 11 in a nearly flat state (i.e., each layer of photovoltaic panel 11 is almost on the same horizontal plane), significantly reducing the volume of the entire device. Then, the telescopic component 19 drives the plate a4 to descend, thereby lowering the entire folding mechanism into the box 1. Finally, the motor a7 is turned on, and the motor a7 drives the gear 14 to rotate. The gear 14 drives the rack 15 to move, causing the sliding covers 2 on both sides to move towards each other. During the movement of the sliding covers 2, the wiping cotton at the bottom of the sliding covers can sweep away the dust and impurities on the surface of the top protective box 9. After the sliding covers 2 close together, they can seal and protect the box 1, thereby protecting the photovoltaic panel 11 and ensuring the safety of the photovoltaic panel 11 in harsh environments.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
