Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, specifically to a photovoltaic support device. Background Technology

[0002] Photovoltaic support equipment is the core infrastructure of a solar photovoltaic power generation system. Its core function is to ensure the stability of photovoltaic modules under various environmental conditions, such as wind, snow, and earthquakes, by fixing, supporting, and adjusting the position and angle of the modules, and to maximize the absorption of solar radiation to improve power generation efficiency. Its structure typically consists of poles, support beams, connectors, foundations such as piles, and concrete blocks.

[0003] For example, an existing Chinese patent (CN119519559A) discloses a support mechanism and photovoltaic equipment for easy installation of photovoltaic modules. It includes a first support, consisting of a first horizontal bar and a first vertical frame fixedly connected to both ends of the first horizontal bar. It also includes a second support, consisting of a second horizontal bar and a second vertical frame fixedly connected to both ends of the second horizontal bar. The second vertical frame includes a combined housing with a driving component on the outside and a transmission component inside. A strip support includes a strip-shaped housing with one end connected to the top of the first vertical frame and the other end connected to the top of the combined housing. A drag chain structure is installed inside the strip-shaped housing, and mounting blocks are fixedly mounted on the drag chain structure. Its advantages are: it does not use a complex mechanism for driving and control, maintains an overall shape similar to a steel structure, and meets the requirements for use in outdoor environments while ensuring stability.

[0004] Currently, most common photovoltaic support systems on the market adopt a design scheme of independent large-size photovoltaic panels with fixed brackets. This structure can operate stably under normal weather conditions, but it has significant defects when facing extreme weather, especially when encountering strong convective weather such as hail. The exposed surface of the photovoltaic panels is directly subjected to the impact of hail, and its core components such as glass cover and solar cells are very likely to suffer irreversible damage such as microcracks and breakage due to impact.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example 1: Please refer to Figures 1-5 This invention provides a technical solution: a photovoltaic support device, including a protective shell 1 and a scissor-type telescopic frame 3. The scissor-type telescopic frame 3 is provided between the inner walls of both sides of the protective shell 1. The bottom of one end of the scissor-type telescopic frame 3 is provided with a fixed shaft 13, and the top is provided with a lifting shaft 14. The lifting shaft 14 can slide up and down inside the protective shell 1. One end of the scissor-type telescopic frame 3 forms a fixed fulcrum with the inner wall of the protective shell 1 through the fixed shaft 13, and the other end is a movable end. When the scissor-type telescopic frame 3 extends or retracts, the lifting shaft 14 at the top slides up and down along the trajectory of the inner wall of the protective shell 1, and cooperates with the fixed shaft 13 to realize the expansion and contraction of the frame. The scissor-type telescopic frame 3, together with the fixed shaft 13 and the lifting shaft 14, enables the flexible unfolding and retraction of the photovoltaic panel 4. When unfolded, it ensures that the photovoltaic panel 4 receives sufficient sunlight, and when retracted, it reduces the size of the equipment. When encountering severe weather such as hail, the scissor-type telescopic frame 3 can quickly retract to completely retract the photovoltaic panel 4 into the protective shell 1. The protective shell 1, as the first line of defense, can effectively prevent hail from directly impacting the photovoltaic panel 4, thus avoiding damage such as cracks and breaks in the photovoltaic panel 4.

[0023] The other end of the scissor-type telescopic frame 3 is equipped with a support shaft 15, and drive wheels 6 are provided at both ends of the support shaft 15. A drive motor 7 is fixed to the bottom outer wall of the support shaft 15. One end of the output shaft of the drive motor 7 is fixed to the center of one end of the drive wheel 6. Support wheels 5 are provided on both sides of the bottom of the scissor-type telescopic frame 3. The drive wheels 6 at both ends of the support shaft 15 are driven to rotate by the drive motor 7, providing power for the overall movement of the equipment. The support wheels 5 at the bottom of the scissor-type telescopic frame 3 assist in supporting the weight of the frame body and reducing friction during movement. The drive motor 7 drives the drive wheels 6 in conjunction with the support wheels 5, enabling the equipment to move autonomously, improving the site adaptability of the equipment, and facilitating the adjustment of the installation position according to the lighting conditions.

[0024] The protective casing 1 has an opening on one side, and a water tank 2 is located on the top of the protective casing 1. The opening on one side of the protective casing 1 provides a passage for the unfolding and retraction of the scissor-type telescopic frame 3. The water tank 2 stores water in advance to provide a water source for subsequent cleaning of the photovoltaic panels 4, eliminating the need for an external water source and enhancing the independence of the equipment.

[0025] An electro-hydraulic rod 8 is fixed to the outer wall of the middle section of the support shaft 15. A pressure plate is located at the bottom of the electro-hydraulic rod 8, and anti-slip textures are formed on the bottom surface of the pressure plate. The electro-hydraulic rod 8 is fixed to the movable end of the scissor-type telescopic frame 3 via the support shaft 15. When the equipment moves to the target position or the scissor-type telescopic frame 3 unfolds, the electro-hydraulic rod 8 extends, pushing the bottom pressure plate downwards until the pressure plate is tightly pressed against the ground. The anti-slip textures on the bottom surface of the pressure plate increase the coefficient of friction with the ground, enhancing the static friction after contact. The telescopic movement of the electro-hydraulic rod 8 allows for quick fixing and unlocking of the equipment, making operation convenient and efficient. The large contact area between the pressure plate and the ground, combined with the anti-slip textures, effectively resists external forces such as wind, preventing the equipment from shifting or tipping over during operation and improving the stability of the equipment in outdoor environments.

[0026] A photovoltaic panel 4 is fixed to the top surface of one side of the scissor-type telescopic frame 3. There are multiple photovoltaic panels 4, which are arranged in parallel on the scissor-type telescopic frame 3. The photovoltaic panels 4 are directly fixed to the top surface of the scissor-type telescopic frame 3 and move synchronously with the expansion and contraction of the scissor-type telescopic frame 3. This achieves rapid expansion for lighting and safe storage of the photovoltaic panels 4, with strong operational continuity. The parallel arrangement of multiple photovoltaic panels 4 maximizes the use of the top surface space of the scissor-type telescopic frame 3, increases the power generation capacity of the equipment, and ensures that the light-receiving angle of each photovoltaic panel 4 is basically the same.

[0027] The protective outer shell 1 has vertical lifting slots 12 on both sides, and the two ends of the lifting shaft 14 are located inside the vertical lifting slots 12, allowing the lifting shaft 14 to slide up and down within them. The vertical lifting slots 12 provide a precise sliding trajectory for the lifting shaft 14. When the scissor-type telescopic frame 3 extends or retracts, the two ends of the lifting shaft 14 are confined within the vertical lifting slots 12, and can only slide up and down along the vertical trajectory of the slots. This prevents lateral deviation of the lifting shaft 14, ensuring the smoothness and stability of the scissor-type telescopic frame 3's extension and retraction, and preventing the frame from jamming or becoming stuck due to deviation of the lifting shaft 14. The symmetrical vertical lifting slots 12 on both sides ensure even force distribution on the lifting shaft 14, improving the structural stability of the scissor-type telescopic frame 3 after deployment.

[0028] This invention utilizes a scissor-type telescopic frame 3 as its core to achieve efficient folding and storage of photovoltaic panels 4. One end of the scissor-type telescopic frame 3 is positioned by a fixed shaft 13, while the other end is moved via a support shaft 15. The top lifting shaft 14 slides along the vertical lifting groove 12 of the protective shell 1, forming a stable telescopic trajectory, allowing multiple parallel photovoltaic panels 4 to be simultaneously unfolded or stored. When unfolded, the photovoltaic panels 4 can be fully extended to obtain the maximum light-receiving area, improving power generation efficiency. When stored, the photovoltaic panels 4 retract into the protective shell 1 along with the scissor-type telescopic frame 3, significantly reducing the equipment volume and facilitating transportation, storage, and relocation. Simultaneously, the electro-hydraulic rod 8 on the support shaft 15, in conjunction with an anti-slip pressure plate, can quickly fix the equipment after unfolding, ensuring the stability of the photovoltaic panels 4 during operation. The synchronous drive motor 7 drives the drive wheels 6, enabling the equipment to be flexibly moved to the position with optimal lighting conditions, further improving photovoltaic utilization efficiency.

[0029] When encountering severe weather such as hail, the scissor-type telescopic frame 3 can quickly retract, completely retracting the photovoltaic panel 4 into the protective shell 1. The protective shell 1 acts as the first line of defense, effectively preventing hail from directly impacting the photovoltaic panel 4 and avoiding damage such as cracks or breaks. Simultaneously, the photovoltaic panel 4, once retracted, is within a closed space, preventing secondary damage from rainwater immersion and strong winds. Furthermore, when the equipment is deployed, the scissor-type telescopic frame 3, through the cooperation of the lifting shaft 14 and the vertical lifting groove 12, the auxiliary support of the support wheels 5, and the fixing effect of the electro-hydraulic rod 8, forms a stable frame structure that can resist external forces such as strong winds, reducing the impact of extreme weather on the overall structure of the equipment and providing indirect protection for the photovoltaic panel 4.

[0030] Example 2: Please refer to Figures 1-10This invention provides a technical solution: a photovoltaic support device, including a protective shell 1 and a scissor-type telescopic frame 3. The scissor-type telescopic frame 3 is provided between the inner walls of both sides of the protective shell 1. The bottom of one end of the scissor-type telescopic frame 3 is provided with a fixed shaft 13, and the top is provided with a lifting shaft 14. The lifting shaft 14 can slide up and down inside the protective shell 1. One end of the scissor-type telescopic frame 3 forms a fixed fulcrum with the inner wall of the protective shell 1 through the fixed shaft 13, and the other end is a movable end. When the scissor-type telescopic frame 3 extends or retracts, the lifting shaft 14 at the top slides up and down along the trajectory of the inner wall of the protective shell 1, and cooperates with the fixed shaft 13 to realize the expansion and contraction of the frame. The scissor-type telescopic frame 3, together with the fixed shaft 13 and the lifting shaft 14, enables the flexible unfolding and retraction of the photovoltaic panel 4. When unfolded, it ensures that the photovoltaic panel 4 receives sufficient sunlight, and when retracted, it reduces the size of the equipment. When encountering severe weather such as hail, the scissor-type telescopic frame 3 can quickly retract to completely retract the photovoltaic panel 4 into the protective shell 1. The protective shell 1, as the first line of defense, can effectively prevent hail from directly impacting the photovoltaic panel 4, thus avoiding damage such as cracks and breaks in the photovoltaic panel 4.

[0031] The other end of the scissor-type telescopic frame 3 is equipped with a support shaft 15, and drive wheels 6 are provided at both ends of the support shaft 15. A drive motor 7 is fixed to the bottom outer wall of the support shaft 15. One end of the output shaft of the drive motor 7 is fixed to the center of one end of the drive wheel 6. Support wheels 5 are provided on both sides of the bottom of the scissor-type telescopic frame 3. The drive wheels 6 at both ends of the support shaft 15 are driven to rotate by the drive motor 7, providing power for the overall movement of the equipment. The support wheels 5 at the bottom of the scissor-type telescopic frame 3 assist in supporting the weight of the frame body and reducing friction during movement. The drive motor 7 drives the drive wheels 6 in conjunction with the support wheels 5, enabling the equipment to move autonomously, improving the site adaptability of the equipment, and facilitating the adjustment of the installation position according to the lighting conditions.

[0032] The protective casing 1 has an opening on one side, and a water tank 2 is located on the top of the protective casing 1. The opening on one side of the protective casing 1 provides a passage for the unfolding and retraction of the scissor-type telescopic frame 3. The water tank 2 stores water in advance to provide a water source for subsequent cleaning of the photovoltaic panels 4, eliminating the need for an external water source and enhancing the independence of the equipment.

[0033] Please refer to the following: Figures 6-10The rest is the same as in Embodiment 1. In this embodiment, water spray pipes 17 are slidably provided on both sides of the inner wall of the upper half of the protective shell 1. Multiple water spray heads are provided at the bottom of the water spray pipes 17, and these heads are arranged equidistantly at the bottom of the water spray pipes 17. One end of the water spray pipe 17 is connected to the water tank 2. The water spray pipes 17 are installed on the inner wall of the upper half of the protective shell 1 and can be slidably adjusted along the inner wall. Water in the water tank 2 is transported to the water spray pipes 17 through connecting pipes and then sprayed out through the multiple water spray heads at the bottom. The equidistant arrangement of the water spray heads causes the sprayed water to form a uniform water curtain covering the surface of the photovoltaic panel 4. The sliding design of the water spray pipe 17, combined with the equidistant spray heads, achieves comprehensive cleaning of the photovoltaic panel 4 surface, avoiding cleaning dead corners. The evenly distributed spray heads ensure uniform water pressure and flow distribution, effectively removing dust and debris from the photovoltaic panel 4 surface while preventing damage to the photovoltaic panel 4 from excessive local water flow. The water spray pipe 17 is directly connected to the water tank 2, forming an independent cleaning water supply system that does not rely on external water sources, thus improving the outdoor adaptability of the equipment.

[0034] The protective housing 1 has lead screws 18 on both inner walls and lead screw nuts 20 on the outer walls of the lead screws 18. A support rod 16 is provided between the lead screws and nuts 20, and a water spray pipe 17 is fixed to the bottom of the support rod 16. The lead screws 18 are connected to the inner walls of the protective housing 1 through bearing seats. The lead screw nuts 20 are threadedly engaged with the lead screws 18. The support rod 16 connects the lead screw nuts 20 on both sides to form a stable beam structure. The water spray pipe 17 is fixed to the bottom of the support rod 16. When the lead screws 18 rotate, the lead screw nuts 20 convert the rotational motion of the lead screws 18 into linear motion, moving along the axis of the lead screws 18, driving the support rod 16 and the water spray pipe 17 to move synchronously, ensuring the uniformity of the cleaning process.

[0035] A water pipe adjustment groove 22 is provided in the middle of the support rod 16. A C-type pipe clamp 23 is fixed to the outer wall of the water spray pipe 17. The top of the C-type pipe clamp 23 is connected to the support rod 16 by bolts. The water pipe adjustment groove 22 is a long strip. The C-type pipe clamp 23 clamps and fixes the water spray pipe 17. The bolts at the top of the C-type pipe clamp 23 pass through the water pipe adjustment groove 22 and are connected to the support rod 16. When the bolts are loosened, the C-type pipe clamp 23 can move along the length of the water pipe adjustment groove 22 to adjust the lateral position of the water spray pipe 17. After adjustment, the bolts are tightened to fix it. The clamping and fixing method of the C-type pipe clamp 23 not only ensures the installation stability of the water spray pipe 17, but also facilitates the disassembly and maintenance of the water spray pipe 17, reducing the later maintenance cost.

[0036] A water pump 9 is installed at the bottom of one side of the outer wall of the water tank 2. One end of the water pump 9 is connected to the water tank 2, and one end of the water pump 9 is connected to a flexible hose 10. One end of the flexible hose 10 is connected to one end of the spray pipe 17. The end of the spray pipe 17 away from the flexible hose 10 is a closed end. The closed end design of the spray pipe 17 ensures uniform water pressure inside the pipe, making the water output of each spray head consistent, and further improving the uniformity of cleaning. A flexible hose moving groove 11 is opened on one side of the protective shell 1, outside the flexible hose 10. The flexible connection of the flexible hose 10, in conjunction with the flexible hose moving groove 11, adapts to the horizontal movement of the spray pipe 17, avoiding damage to the water supply pipeline due to pulling and extending the service life of the pipeline. Water pump 9 provides power for the cleaning water supply. During operation, it draws clean water from the bottom of water tank 2, delivers it through the outlet to hose 10, and then guides it into spray pipe 17. The end of spray pipe 17 away from hose 10 is sealed to ensure stable water pressure inside the pipe and uniform water output from each spray head. When spray pipe 17 moves horizontally, hose 10 can extend or move along hose movement groove 11 to avoid tangling or pulling. This effectively removes stubborn stains from the surface of photovoltaic panel 4, improving the cleaning effect.

[0037] The inner wall of the protective housing 1 is provided with guide bars 21 on both sides. A guide groove is provided on one side of the lead screw nut 20 to cooperate with the guide bars 21. The lead screw nut 20 can slide along the guide bars 21. When the lead screw 18 rotates, the guide bars 21 restrict the rotation of the lead screw nut 20 through the guide groove, ensuring that the lead screw nut 20 can only translate along the axis of the guide bars 21. The cooperation between the guide bars 21 and the guide groove eliminates the rotational freedom of the lead screw nut 20, ensuring that the rotational motion of the lead screw 18 is accurately converted into the translational motion of the lead screw nut 20, thus improving the movement accuracy of the water spray pipe 17. Furthermore, the guiding effect reduces the radial force between the lead screw 18 and the lead screw nut 20, reduces thread wear, and extends the service life of the transmission components. The symmetrical guide bars 21 on both sides ensure that the force on the lead screw nut 20 is balanced, preventing deviation during movement and ensuring the smooth translation of the water spray pipe 17.

[0038] Motor brackets 24 are provided on both sides of the outer wall of the support shaft 15. The drive motor 7 is fixed to one side of the motor bracket 24. The motor bracket 24 provides fixed support for the drive motor 7, stably mounting the drive motor 7 on both sides of the support shaft 15. The motor bracket 24 improves the installation stability of the drive motor 7, preventing the drive motor 7 from loosening due to vibration during operation and ensuring the power transmission efficiency of the drive wheel 6. The two drive motors 7 are also synchronous motors, and the two drive motors 7 are controlled synchronously to ensure that the rotation speed of the drive wheel 6 on both sides is consistent, so that the equipment does not deviate when moving linearly, improving the movement accuracy and stability of the equipment.

[0039] Servo motors 19 are installed on both sides of the outer wall of the protective housing 1. The two servo motors 19 are synchronous motors. One end of the output shaft of the servo motor 19 is fixed to one end of the lead screw 18. The servo motor 19 is fixed to the outer wall of the protective housing 1, and its output shaft is directly connected to the lead screw 18 to provide power for the rotation of the lead screw 18. The two servo motors 19 adopt synchronous control to ensure that the speed and direction of the lead screw 18 on both sides are consistent. The synchronous servo motors 19 ensure that the lead screw 18 on both sides rotates synchronously, so that the support rod 16 and the water spray pipe 17 always maintain horizontal translation, avoiding equipment jamming or damage due to inconsistent movement speed on both sides.

[0040] The water tank 2 at the top of the protective casing 1 stores cleaning water in advance. The water pump 9 provides stable power to deliver water to the spray pipe 17. The spray nozzles at equal intervals at the bottom of the spray pipe 17 can form a uniform water curtain. During cleaning, the synchronous servo motors 19 on both sides drive the lead screw 18 to rotate. The lead screw nut 20 moves smoothly along the guide bar 21, and the support rod 16 drives the spray pipe 17 to move laterally along the surface of the photovoltaic panel 4 to achieve full coverage cleaning. The position of the spray pipe 17 can be adjusted along the water pipe adjustment groove 22 by the C-type pipe clamp 23 to adapt to the arrangement of photovoltaic panels 4 of different widths, ensuring no cleaning dead corners. The hose 10 works with the hose moving groove 11 to avoid pipe tangling when the spray pipe 17 moves, further improving the cleaning stability. The entire cleaning device does not require an external water source or additional cleaning equipment. It can complete the cleaning while the photovoltaic panel 4 is in the protected state, which not only ensures the cleaning effect but also avoids accidental damage to the photovoltaic panel 4 during the cleaning process.
