Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and more specifically, to a photovoltaic support structure that is adaptive and conveniently adjustable to mountainous terrain. Background Technology

[0002] Constructing photovoltaic power plants in complex terrain environments such as mountainous areas presents technical challenges, including significant slope variations, uneven ground, and difficulties in standardizing installation reference surfaces. Traditional photovoltaic support systems often employ rigid, fixed structures with limited height and tilt adjustment capabilities. This frequently necessitates extensive on-site cutting, welding, or custom foundation work, resulting in low construction efficiency, high costs, and difficulty in ensuring the flatness and structural stability of the module installation surface. Particularly in areas with frequent slope undulations, uneven stress distribution across the support points can easily lead to settlement, tilting, or even structural failure, severely impacting the long-term safe operation and power generation efficiency of the photovoltaic system.

[0003] While some adjustable support solutions exist in existing technologies, they generally suffer from problems such as complex adjustment mechanisms, cumbersome operation, and insufficient locking reliability. For example, some supports use multi-point independent adjustment methods, requiring individual adjustment of the support height, making it difficult to achieve overall synchronous leveling; other solutions, although incorporating gear and rack or screw mechanisms, lack effective self-locking and anti-loosening structures, making them prone to displacement under vibration or wind loads. Furthermore, the sub-beams of most supports rely on bolts for individual tightening, resulting in low installation efficiency and failing to meet the engineering requirements of rapid deployment and high adaptability for mountain photovoltaic projects.

[0004] Therefore, there is an urgent need for a photovoltaic support system that is structurally sound, easy to adjust, reliably locked, and capable of adapting to changes in terrain as a whole, in order to overcome the shortcomings in current practical applications. Summary of the Invention

Combined with the sliding connection between the outer support cylinder and the inner support rod and the lifting and locking mechanism of the adjustment components, it achieves these advantages.

Detailed Implementation

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0028] The following is a detailed description, with reference to the accompanying drawings, of a mountain terrain adaptive and convenient adjustable photovoltaic bracket according to an embodiment of the present invention.

[0029] like Figure 1-5 As shown, an embodiment of the present invention provides a mountain terrain adaptive and convenient adjustable photovoltaic support, including two parallel main support beams 1, and further comprising: Sub-bearing beams 3: Multiple sub-bearing beams 3 are evenly distributed on the upper side of the two main bearing beams 1, and the sub-bearing beams 3 are perpendicular to the main bearing beams 1. A first rod support 11 for supporting the sub-bearing beams 3 is fixed on the main bearing beams 1. Synchronous fixing component: The main bearing beam 1 is equipped with a synchronous fixing component, which is used to synchronously clamp and fix all the secondary bearing beams 3 set on the main bearing beam 1. The second rod support 12 is also adjustable and slidably provided on the lower side of both ends of the main support beam 1. The lower side of the two second rod supports 12 that are far apart is hinged to the outer support cylinder 10. The outer support cylinder 10 and the second rod support 12 are also fixed with a curved arm adjusting rod 6. The curved arm adjusting rod 6 is used to support the outer support cylinder 10 and adjust the angle of the outer support cylinder 10 relative to the second rod support 12. The inner side of the outer support cylinder 10 is slidably provided with a support inner rod 8. The lower end of the support inner rod 8 is fixed with an anti-sinking base plate 7. Adjustment component 9 is detachably installed on the outer support cylinder 10. Adjustment component 9 is used to drive the inner support rod 8 to move relative to the outer support cylinder 10 and to lock and fix the inner support rod 8.

[0030] In this embodiment of the invention, a stable frame structure is formed by the combination of the secondary support beam 3 and the main support beam 1, which facilitates the installation of photovoltaic panels on the foundation plane formed by the main support beam 1 and the secondary support beam 3 (the specific installation structure is not limited or described in detail). By setting the first pole support 11 with the synchronous fixing component, not only can the secondary support beam 3 be stably supported, but all the secondary support beams 3 set on the main support beam 1 can also be clamped and fixed synchronously through the synchronous fixing component, so as to realize the rapid overall locking and fixing after the secondary support beam 3 is placed in the correct position, which significantly improves the installation efficiency.

[0031] The second support rod 12 is adjustable relative to the main support beam 1 to meet special installation requirements and facilitate disassembly. The curved arm adjustment rod 6 facilitates the adjustment of the angle between the outer support cylinder 10 and the second support rod 12, meeting the installation requirements of mountainous terrain and allowing the photovoltaic panels to receive sunlight better. The outer support cylinder 10 and the inner support rod 8 are slidably connected, and the adjustment component 9 is detachable and drives the inner support rod 8 to rise and fall and lock the inner support rod 8 in place, further meeting the needs of adaptive and convenient adjustment installation in mountainous terrain, making it flexible in application.

[0032] In summary, this terrain-adaptive and convenient adjustable photovoltaic support system significantly improves the convenience, stability, and efficiency of photovoltaic panel installation in complex mountainous environments through the stable frame structure of the main support beam 1 and the secondary support beam 3, the rapid overall locking achieved by the synchronous fixing components, the adjustability of the second rod support 12, and the angle adjustment function of the curved arm adjustment rod 6. Combined with the sliding connection between the outer support cylinder 10 and the inner support rod 8 and the lifting and locking mechanism of the adjustment component 9, it achieves these advantages.

[0033] like Figure 1-4 As shown, in a preferred embodiment of the present invention, the first rod support 11 is arranged perpendicular to the main bearing beam 1 and adopts a U-shaped structure with an upper opening. The length of the first rod support 11 is greater than the width of the main bearing beam 1, and the secondary bearing beam 3 can be reliably supported by the first rod support 11.

[0034] The synchronous fixing assembly includes a threaded drive shaft 17 rotatably mounted on the inner side of the main bearing beam 1. One end of the threaded drive shaft 17 is fixed with a first knob 13 for easy control of the rotation of the threaded drive shaft 17. The first rod support 11 has movable openings 15 on both sides at the top of the main bearing beam 1, and clamping openings 16 on both sides of the first rod support 11. The synchronous fixing assembly also includes an inverted L-shaped fixed clamping plate 14. The horizontal part of the fixed clamping plate 14 is slidably connected to the clamping opening 16, and the vertical part of the fixed clamping plate 14 passes through the movable opening 15 and extends into the inner cavity of the main bearing beam 1 and is threadedly connected to the threaded drive shaft 17. When the threaded drive shaft 17 rotates, the two fixed clamping plates 14 on both sides of the first rod support 11 move closer or further away synchronously, so that when the two fixed clamping plates 14 move closer, they can securely abut against the secondary bearing beam 3.

[0035] Optionally, the horizontal portion of the fixed clamping plate 14 is damped and slidably connected to the clamping opening 16, and the threaded drive shaft 17 is damped and rotatably connected to the main bearing beam 1 to ensure reliability after tightening. Alternatively, bolts for locking the threaded drive shaft 17 may be arranged, without limitation or elaboration.

[0036] It should be noted that the connection between the two fixed clamping plates 14 on both sides of the first rod support 11 and the threaded drive shaft 17 can be arranged with positive and negative threads. In this way, when the threaded drive shaft 17 rotates, all the secondary support beams 3 can be clamped and fixed synchronously.

[0037] As described above, the first support 11 with an open U-shaped structure ensures stable support for the secondary support beams 3. The synchronous fixing assembly utilizes the engagement of a threaded drive shaft 17 with both positive and negative threads and an inverted L-shaped fixing clamping plate 14 to achieve rapid and synchronous clamping or releasing of all secondary support beams 3. This design not only improves installation efficiency but also enhances the stability and reliability of the overall structure. Especially in complex terrain conditions, it effectively ensures the stability and flatness of the photovoltaic support system, simplifying the installation and adjustment process. Furthermore, the design of damped sliding and rotating connections further enhances the system's vibration resistance and stability after fastening, reducing the risk of unnecessary loosening.

[0038] like Figure 1-4 As shown, in a preferred embodiment of the present invention, the second rod support 12 adopts an open-top U-shaped structure, and the two sides of the main support beam 1 are integrally formed with detachment blocking ribs 2 that are slidably connected to the inner walls of the two sides of the second rod support 12. This allows the second rod support 12 to be installed only from the end, avoiding longitudinal separation between the main support beam 1 and the second rod support 12 and improving reliability.

[0039] The second rod support 12 is also equipped with a first fixing bolt 4 for locking and fixing it to the main bearing beam 1.

[0040] The crank arm adjusting rod 6 adopts an arc-shaped telescopic adjusting structure. The crank arm adjusting rod 6 is provided with a second fixing bolt 5 for locking after adjustment. The center of the crank arm adjusting rod 6 is located on the hinge axis of the outer support cylinder 10 and the second rod support 12. By controlling the extension and retraction of the crank arm adjusting rod 6, the angle of the outer support cylinder 10 relative to the main support beam 1 can be adjusted, which is stable and reliable.

[0041] As described above, by employing a second rod support 12 with an open U-shaped structure and slidingly connecting it to the detachment-preventing ribs 2 integrally formed with the main bearing beam 1 on both sides, it is ensured that the second rod support 12 can only be installed from the end, effectively preventing longitudinal separation between the main bearing beam 1 and the second rod support 12, and significantly improving the reliability and stability of the system. Furthermore, the application of the first fixing bolt 4 further ensures the secure locking of the second rod support 12 onto the main bearing beam 1, enhancing the overall structural safety.

[0042] The adjustable boom arm 6 is designed as an arc-shaped, telescopic adjustable structure, with its center located on the hinge axis of the outer support cylinder 10 and the second support rod 12. This allows for precise adjustment of the angle of the outer support cylinder 10 relative to the main support beam 1 simply by adjusting the length of the adjustable boom arm 6. This design not only simplifies the angle adjustment process but also provides greater flexibility to adapt to different mountainous terrain conditions. The second fixing bolt 5 is used to lock the adjusted position of the adjustable boom arm 6, ensuring stability at any set angle. This guarantees that the photovoltaic panel can receive sunlight at the optimal angle, improving energy collection efficiency. Overall, these design elements work together to achieve a fast, convenient, and stable installation and adjustment mechanism, which is particularly suitable for complex and varied mountainous environments.

[0043] like Figure 1-3 As shown in Figures 5-7, in a preferred embodiment of the present invention, a side opening 18 is provided on the side wall of the outer support cylinder 10, and a constraint groove 19 is also provided on the side wall of the side opening 18. An assembly groove 20 is provided on the side of the inner support rod 8 near the side opening 18. A rack 21 is installed and fixed in the assembly groove 20, and a locking groove 22 is also provided on one side wall of the assembly groove 20.

[0044] The adjusting assembly 9 includes a constraint plate 28 slidably connected to the constraint groove 19. An adjusting outer cylinder 31 is fixed on the constraint plate 28. A gear 23 capable of meshing with a rack 21 is rotatably mounted on the inner end of the adjusting outer cylinder 31. An adjusting inner rod 33 is slidably and rotatably connected to the inner side of the adjusting outer cylinder 31. A linkage head 25 is provided at the inner end of the adjusting inner rod 33. A linkage groove 24 is opened on the gear 23 corresponding to the linkage head 25. The linkage head 25 can be drivenly connected to the linkage groove 24. A collar 35 is also rotatably connected to the adjusting inner rod 33. An open annular cavity 34 is opened on the adjusting outer cylinder 31 corresponding to the collar 35. A locking rod 26 is fixed on the collar 35 for locking. Rod 26 extends from the opening of the open annular cavity 34, and the end of locking rod 26 away from collar 35 extends into locking groove 22. An elastic element 27 is provided between locking rod 26 and constraint plate 28. The collar 35 allows adjusting inner rod 33 to rotate freely without affecting locking rod 26. Locking rod 26 is limited by the opening of open annular cavity 34, making it stable and reliable. A flat pad 29 is also slidably provided on the side of constraint plate 28 away from locking rod 26 on adjusting outer cylinder 31. A fixing nut 30 is threadedly connected to the side of flat pad 29 away from constraint plate 28 on adjusting outer cylinder 31. A second knob 32 is also fixed to the outer end of adjusting inner rod 33.

[0045] Optionally, both the linkage groove 24 and the linkage head 25 adopt a conical structure, and the surfaces of both the linkage groove 24 and the linkage head 25 are provided with anti-slip protrusions to ensure the reliability of the abutment transmission between the linkage groove 24 and the linkage head 25.

[0046] Optionally, the open annular cavity 34 is used for the movement of the collar 35 and the extension and movement of the locking rod 26, which will not be described in detail. The elastic element 27 is a spring. When there is no external force, the elastic element 27 is used to separate the linkage head 25 and the linkage groove 24. At the same time, the locking rod 26 is fixed to the side wall of the locking groove 22. At this time, the longitudinal movement of the inner support rod 8 is restricted by the locking rod 26 to achieve stability after adjustment. When the second knob 32 is pressed to make the linkage head 25 and the linkage groove 24 connected, the locking rod 26 is separated from the side wall of the locking groove 22. At this time, the second knob 32 can be operated to rotate the inner adjustment rod 33, thereby driving the gear 23 to rotate, and using the meshing relationship between the gear 23 and the rack 21 to drive the inner support rod 8 to move relative to the outer support cylinder 10. In addition, during adjustment, the adjustment component 9 can be pre-installed to a suitable position and the flat washer 29 can be locked to the surface of the outer support cylinder 10 by the fixing nut 30 to ensure the stability of the adjustment component 9 in advance. Then, the adjustment can be made by pressing and rotating the second knob 32. This ensures the flexibility of the installation position of the adjustment component 9 and makes it easy to press the second knob 32 to adjust the inner support rod 8 by using the gear 23 and rack 21 transmission (it can be understood that after pressing the second knob 32 to release the brake of the locking rod 26, the inner support rod 8 can also be pulled directly for quick adjustment, which will not be elaborated).

[0047] Optionally, the contact surfaces of the locking rod 26 and the locking groove 22 are both provided with an anti-slip layer to ensure the reliability of the support fixation. In addition, to further ensure reliability, bolts for locking and fixing the inner rod 8 can be directly arranged on the outer support cylinder 10, or the locking groove 22 can be arranged in a sawtooth or grooved structure to enhance the locking reliability, without limitation or elaboration.

[0048] Preferably, a disc-shaped structure is adopted for the anti-sinking chassis 7 to achieve stable and reliable overall support. The main support beam 1 and the secondary support beam 3 are made of high-strength aluminum alloy or hot-dip galvanized steel with a thickness of 2-5mm to balance weight and strength. The telescopic range of the articulated arm adjustment rod 6 is designed to be 200-800mm, allowing the angle of the outer support cylinder 10 to be adjusted between 0° and 45°, covering most mountain slopes.

[0049] As described above, by opening a side opening 18 in the side wall of the outer support cylinder 10 and installing an inner support rod 8 with a rack 21 inside it, combined with the design of the adjustment assembly 9, precise and convenient adjustment of the height of the inner support rod 8 is achieved. The adjustment assembly 9 includes a constraint plate 28 slidably connected to the outer support cylinder 10 and an adjustment outer cylinder 31 fixed thereon. A gear 23 meshing with the rack 21 is installed inside the adjustment outer cylinder 31, so that rotating the second knob 32 can drive the inner support rod 8 to move relative to the outer support cylinder 10 through gear and rack transmission, thereby achieving height adjustment. The locking rod 26 and the locking groove 22 cooperate to ensure the stability after adjustment and prevent the inner support rod 8 from moving accidentally.

[0050] The adjusting inner rod 33 is connected to the locking rod 26 via a collar 35, allowing it to rotate freely without affecting the position of the locking rod 26, thus increasing operational flexibility. The elastic element 27 (spring) ensures that the locking rod 26 is in close contact with the locking groove 22 without external force, enhancing the system's self-locking performance. Furthermore, the application of the flat washer 29 and the fixing nut 30 further ensures the stability of the adjusting assembly 9's installation position, making the entire adjustment process both flexible and reliable.

[0051] The linkage head 25 and linkage groove 24 adopt a conical structure and are equipped with anti-slip ridges, which improves transmission efficiency and reliability. This design not only simplifies the adjustment process, but also provides stable support under complex terrain conditions, adapts to different ground height changes, and greatly improves the adaptability and installation efficiency of the photovoltaic support system.

[0052] The specific installation process is as follows: During installation, first place the main support beam 1 on the mountainous terrain, adjust the support point position by sliding the second rod support 12, and lock it with the first fixing bolt 4. Then, adjust the length of the curved arm adjusting rod 6 to set the angle of the outer support cylinder 10, and fix it with the second fixing bolt 5. Next, install the adjusting component 9 onto the outer support cylinder 10 and pre-tighten it with the fixing nut 30. Press and rotate the second knob 32 to drive the inner support rod 8 up and down until the required installation angle and height are reached (the heights at both ends are not the same to achieve the purpose of angle adjustment), and release the second knob 32 to automatically lock it. Finally, place the secondary support beam 3 on the first rod support 11 and adjust its position. Rotate the first knob 13 to lock all the secondary support beams 3 with the synchronous fixing component, and the photovoltaic panel can be installed.

[0053] The above embodiments of the present invention provide a convenient and adaptive photovoltaic support for mountainous terrain, the working principle of which is as follows: Two main support beams 1 are arranged in parallel, with multiple secondary support beams 3 evenly distributed on their upper sides, perpendicular to the main support beams 1. The secondary support beams 3 are supported by first rod supports 11 fixed to the main support beams 1. A synchronous fixing assembly is installed inside the main support beams 1. This assembly includes a threaded drive shaft 17 and a first knob 13. The threaded drive shaft 17 has positive and negative threads corresponding to the fixed clamping plates 14, and the fixed clamping plates 14 are threadedly connected to it. The vertical part of the fixed clamping plate 14 passes through the movable opening 15 at the top of the main support beam 1, and its horizontal part slides into the clamping openings 16 on both sides of the first rod support 11. Rotating the first knob 13 drives the threaded drive shaft 17 to rotate, causing the fixed clamping plates 14 on both sides of each secondary support beam 3 to move synchronously towards or away from each other, thereby achieving synchronous clamping or release of all secondary support beams 3.

[0054] The main support beam 1 has two adjustable second rod supports 12 at its lower ends. The second rod supports 12 have an open U-shaped structure, and their inner walls slide against the anti-detachment ribs 2 integrally formed on both sides of the main support beam 1 to prevent longitudinal detachment. They are also locked in place by the first fastening bolts 4. The lower outer end of the second rod supports 12 is hinged to a supporting outer cylinder 10. A curved arm adjusting rod 6 is provided between the two. The curved arm adjusting rod 6 is an arc-shaped telescopic structure with its center located on the hinge axis. By adjusting its length and locking it with the second fastening bolts 5, the inclination angle of the supporting outer cylinder 10 relative to the main support beam 1 can be changed to adapt to the mountain slope.

[0055] An inner support rod 8 is slidably mounted inside the outer support cylinder 10, and an anti-sinking plate 7 is fixed to the lower end of the inner support rod 8. A side opening 18 is provided on the side wall of the outer support cylinder 10, and a limiting groove 19 is provided on its inner side. A mounting groove 20 is provided on the corresponding side of the inner support rod 8, and a rack 21 is fixed within the mounting groove 20. A fixing groove 22 is also provided on the side wall of the mounting groove 20. An adjusting assembly 9 is detachably mounted on the outside of the outer support cylinder 10, including a limiting plate 28 slidably connected to the limiting groove 19. An adjusting outer cylinder 31 is fixed on the limiting plate 28, and a gear 23 that meshes with the rack 21 is rotatably mounted on the inner end of the adjusting outer cylinder 31. An adjusting inner rod 33 is slidably and rotatably connected to the adjusting outer cylinder 31, and a linkage head 25 is provided on its inner end. A linkage groove 24 that engages with the gear 23 is provided on the gear 23. A collar 35 is rotatably connected to the adjusting inner rod 33, and a locking rod 26 is fixed to the collar 35. The locking rod 26 passes through the open annular cavity 34 on the adjusting outer cylinder 31 and extends into the fixing groove 22. The elastic element 27 is located between the locking rod 26 and the limiting plate 28. When there is no external force, it pushes the locking rod 26 against the side wall of the fixing groove 22 to lock the inner rod 8; at the same time, it separates the linkage head 25 from the linkage groove 24.

[0056] When the second knob 32 is pressed, the linkage head 25 inserts into the linkage slot 24 to form a transmission connection, and at the same time, the locking rod 26 disengages from the fixing slot 22. At this time, rotating the second knob 32 can drive the gear 23 to rotate, and through the meshing of the gear 23 and the rack 21, the inner support rod 8 is driven to rise and fall. After releasing the second knob 32, the elastic element 27 returns to its original position and relocks the inner support rod 8. A flat pad 29 and a nut 30 are provided on the outer side of the adjusting outer cylinder 31 in sequence, which are used to pre-tighten and fix the adjusting component 9 on the supporting outer cylinder 10 to ensure that the adjustment process is stable and reliable.

[0057] In summary, the bracket forms a stable installation platform with the secondary support beam 3 and the main support beam 1, and the secondary support beam 3 is quickly and integrally locked using synchronous fixing components. Through the triple adaptive mechanism of sliding adjustment of the second pole support 12, angle adjustment of the curved arm telescopic rod 6, and height adjustment of the inner support rod 8, it can flexibly adapt to complex mountainous terrain and achieve convenient, stable, and efficient installation of photovoltaic brackets.
