Description

Technical Field

[0001] This invention relates to photovoltaic power generation technology, and more specifically to an adjustable support device for mountain photovoltaic arrays based on terrain adaptation. Background Technology

[0002] With the continuous growth of global energy demand and the rapid development of renewable energy technologies, photovoltaic power generation, as a clean and sustainable energy form, has been widely used around the world. Especially in mountainous areas with complex terrain and abundant sunshine resources, the construction of mountain photovoltaic power stations has become an important way to utilize solar energy resources. Traditional photovoltaic support systems are mainly designed for flat or gently sloping ground and are difficult to apply directly to mountainous environments. To adapt to the diversity and complexity of mountainous terrain, mountain photovoltaic array support devices need to have terrain self-adaptability to ensure that photovoltaic panels can maintain stable and efficient power generation performance under different slopes and geological conditions. In recent years, although some photovoltaic support solutions for mountainous environments have been proposed, such as adjustable-angle supports and segmented supports, these solutions often focus on solving single-dimensional problems, such as only considering angle adjustment without fully addressing terrain adaptability and foundation stability issues.

[0003] However, existing mountain photovoltaic array support devices generally suffer from insufficient terrain adaptability when facing complex and varied mountainous terrain. Traditional support structures often rely on fixed-length support legs or simple angle adjustment mechanisms, making it difficult to make precise adjustments according to the actual terrain. This leads to installation difficulties in areas with large slope variations or complex geological conditions. In particular, when hard and soft soils alternate, traditional support devices cannot simultaneously ensure overturning stability and foundation settlement prevention. They are prone to tilting or even collapsing under extreme weather conditions (such as strong winds and heavy rain) due to unstable foundations, which seriously affects the safe operation and power generation efficiency of photovoltaic power stations. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable support device for mountain photovoltaic arrays based on terrain adaptation, so as to solve the problem that the existing mountain photovoltaic array support devices have insufficient terrain adaptability, making it difficult to achieve rapid and stable installation in complex and ever-changing mountainous terrains and ensure long-term reliable operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable support device for a mountain photovoltaic array based on terrain adaptation, comprising a mounting base plate, wherein inclined inserts are installed around the bottom of the mounting base plate, and a drive assembly is installed on the top of the mounting base plate;

[0006] The inner wall of the inclined insertion rod is rotatably connected to a connecting rod, and the two ends of the connecting rod are rotatably connected to two opposing threaded rods. The surface of the threaded rod is threadedly connected to a limiting sleeve rod, and the surface of the limiting sleeve rod is inserted into the inner wall of the inclined insertion rod. The inner wall of the inclined insertion rod is equipped with a positioning rod, and the two ends of the positioning rod are respectively inserted into the inner walls of the two threaded rods. The surface of the connecting rod is equipped with a first transmission gear, and the first transmission gear is connected to a drive assembly for driving it to rotate around its own axis.

[0007] The mounting base plate has a detachable counterweight on its peripheral side.

[0008] Furthermore, the mounting base plate has insertion slots on all four sides of its surface. A limiting plate is installed on the inner wall of the insertion slot. An installation block is inserted into the inner wall of the insertion slot, and the surface of the limiting plate is inserted into the inner wall of the installation block. One side of the installation block is installed on one side of the counterweight plate.

[0009] Furthermore, protective sleeve frames are fixedly connected to both sides of the top of the mounting base plate, a drive rod is rotatably connected to the top of the protective sleeve frame, a handle is installed at the top of the drive rod, a sealing cover is inserted into the top of the protective sleeve frame, and the inner wall of the sealing cover is fitted onto the surface of the handle and the drive rod, and a first drive gear is installed at the bottom of the drive rod.

[0010] Furthermore, the surface of the first drive gear is meshed with a first connecting gear, the inner wall of the first connecting gear is equipped with a first transmission rod, both ends of the first transmission rod are equipped with second connecting gears, the surface of the second connecting gear is meshed with a third connecting gear, the bottom of the third connecting gear is equipped with a second transmission rod, and the surface of the second transmission rod is rotatably connected to the inner wall of the inclined insert rod, the bottom end of the second transmission rod is equipped with a fourth connecting gear, and the surface of the fourth connecting gear is meshed with the surface of the first transmission gear. The drive rod, grip, first drive gear, first connecting gear, first transmission rod, second connecting gear, third connecting gear, second transmission rod, and fourth connecting gear together constitute a drive assembly.

[0011] Furthermore, a support column is installed on the top of the mounting base plate, a rotating bracket is rotatably connected to the inner wall of the support column, and a mounting bracket is installed on the top of the rotating bracket.

[0012] Furthermore, a connecting rod is installed on one side of the rotating bracket, and a second transmission gear is installed on the surface of the connecting rod.

[0013] Furthermore, an installation sleeve is installed on one side of the top of the support column, and the inner wall of the installation sleeve is fitted onto the surface of the second transmission gear. A handle is rotatably connected to one side of the installation sleeve, and a second drive gear is installed on one side of the handle. A connecting gear is meshed with the surface of the second drive gear, and the surface of the connecting gear is meshed with the surface of the second transmission gear.

[0014] Furthermore, a positioning tube is installed on one side of the connecting gear, and a limiting tooth groove is formed on one side of the positioning tube.

[0015] Furthermore, a pull rod is inserted into the inner wall of the mounting box, and sliding blocks are installed around the surface of the pull rod. The surfaces of the sliding blocks are slidably connected to the inner wall of the mounting box. A limit plate is installed at one end of the pull rod, and the surface of the limit plate is inserted into the inner wall of the limit groove.

[0016] Furthermore, an assembly column is installed on the inner wall of the support column, and a connecting chain is installed on the surface of the assembly column.

[0017] Furthermore, a turnbuckle is installed at the bottom end of the connecting chain, and an anchor rod is installed at the bottom end of the turnbuckle.

[0018] Compared with existing technologies, the terrain-adaptive adjustable support device for mountain photovoltaic arrays provided by this invention achieves rapid adaptive installation in complex mountainous terrains through the arrangement of a base plate, tilting rods, limiting sleeves, driving components, transmission components, and counterweights. The initial positioning by the tilting rods and the extension / retraction of the limiting sleeves embedding into the soil form a reliable pull-out resistant structure, effectively preventing the entire device from being pulled upwards. Simultaneously, the installation method of the counterweights can be flexibly selected according to different geological conditions. In hard soil conditions, increasing the overall weight improves overturning stability; in soft soil conditions, expanding the bottom bearing area and adding edge counterweights prevents foundation settlement and lateral slippage. Thus, it achieves the effects of adapting to various mountainous terrains, enhancing foundation stability, and ensuring long-term reliable operation of the device.

[0019] By incorporating support columns, rotating brackets, mounting brackets, a second transmission gear, a second drive gear, and connecting gears, the installation angle of the photovoltaic panels can be flexibly adjusted and precisely positioned. The rotating bracket is rotated by the handle-driven gear transmission system, allowing the photovoltaic panels to adjust to the optimal receiving position according to changes in the angle of sunlight. Simultaneously, the mechanical locking of the rotation angle is achieved through the cooperation between the limit plate controlled by the pull rod and the positioning tube tooth groove, ensuring that the photovoltaic panels maintain a stable orientation under external forces such as wind loads. This achieves the effects of improving photovoltaic power generation efficiency, enhancing the system's wind resistance, and ensuring the long-term stable operation of the photovoltaic panels.

[0020] By installing columns, connecting chains, turnbuckles, and anchor bolts, deep anchoring and prestress adjustment of the entire device are achieved. By driving anchor bolts deep into the rock or soil of the slope to form stable anchor points, and using turnbuckles to precisely adjust the length and tension of the connecting chains, a continuous pre-tension force pointing towards the inside of the slope is applied to the support columns and the upper structure. This effectively balances the overturning moment generated by the photovoltaic array due to its own weight and wind pressure, thereby significantly enhancing the overall wind resistance of the device, improving its anti-overturning stability, preventing foundation deformation and displacement, and ensuring long-term safe operation in steep or loose soil mountainous environments.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] As attached Figure 1 To be continued Figure 10 As shown:

[0036] Example 1:

[0037] The present invention provides an adjustable support device for mountain photovoltaic array based on terrain adaptation, including a mounting base plate 1, inclined insert rods 2 installed around the bottom of the mounting base plate 1, a driving component installed on the top of the mounting base plate 1, and a transmission component connected to one side of the driving component.

[0038] The inner wall of the inclined insertion rod 2 is rotatably connected to a connecting rod 3. The two ends of the connecting rod 3 are rotatably connected to two opposing threaded rods 4. The surface of the threaded rod 4 is threadedly connected to a limiting sleeve 5, and the surface of the limiting sleeve 5 is inserted into the inner wall of the inclined insertion rod 2. The inner wall of the inclined insertion rod 2 is equipped with a positioning rod 6, and the two ends of the positioning rod 6 are respectively inserted into the inner walls of the two threaded rods 4. The surface of the connecting rod 3 is equipped with a first transmission gear 7, and the first transmission gear 7 is connected to the transmission component.

[0039] The mounting base plate 1 has insertion slots 8 on all four sides of its surface. Limiting plates 9 are installed on the inner walls of the insertion slots 8. Mounting blocks 10 are inserted into the inner walls of the insertion slots 8, and the surface of the limiting plates 9 is inserted into the inner wall of the mounting blocks 10. A counterweight 11 is installed on the surface of the mounting blocks 10. Protective frames 12 are fixedly connected to both sides of the top of the mounting base plate 1. A drive rod 13 is rotatably connected to the top of the protective frame 12. A handle 14 is installed at the top of the drive rod 13. A sealing cover 15 is inserted into the top of the protective frame 12, and the inner wall of the sealing cover 15 fits onto the surfaces of the handle 14 and the drive rod 13. A first drive gear 16 is installed at the bottom of the drive rod 13. The drive rod 13, handle 14, and first drive gear 16 together form a driving component. A first connecting gear 17 is meshed with the surface of wheel 16. A first transmission rod 18 is installed on the inner wall of the first connecting gear 17. A second connecting gear 19 is installed at both ends of the first transmission rod 18. A third connecting gear 20 is meshed with the surface of the second connecting gear 19. A second transmission rod 21 is installed at the bottom of the third connecting gear 20, and the surface of the second transmission rod 21 is rotatably connected to the inner wall of the inclined insert rod 2. A fourth connecting gear 22 is installed at the bottom end of the second transmission rod 21, and the surface of the fourth connecting gear 22 is meshed with the surface of the first transmission gear 7. The first connecting gear 17, the first transmission rod 18, the second connecting gear 19, the third connecting gear 20, the second transmission rod 21, and the fourth connecting gear 22 together form a transmission component.

[0040] In use, the base plate 1 serves as the foundation support platform, and the inclined rods 2 around its bottom can be inserted into the hillside terrain for initial positioning and support. The connecting rods 3 inside the inclined rods 2 are rotatably connected at both ends to two opposing threaded rods 4. The threads on the surface of the threaded rods 4 are fitted with limiting sleeves 5, which are inserted into the inner wall of the inclined rods 2 and axially limited by positioning rods 6 passing through the two threaded rods 4. When the connecting rod 3 rotates, the limiting sleeves 5 on both sides move axially along the threaded rods 4 through the threaded transmission, thus extending out of the surface of the inclined rod 2 and inserting into the surrounding soil, forming an anti-pull-out structure to prevent the entire device from being pulled upwards. The first transmission gear 7 installed on the connecting rod 3 is connected to the transmission system, which consists of a drive rod 13, a handle 14, and a first drive gear 16. Rotating the handle 14 drives the drive rod 13, which in turn drives the first drive gear 16 to rotate, thereby meshing... The first connecting gear 17 drives the first transmission rod 18 to rotate. The second connecting gears 19 at both ends of the first transmission rod 18 respectively mesh with the third connecting gear 20. The third connecting gear 20 meshes with the first transmission gear 7 through the fourth connecting gear 22 at the bottom of the second transmission rod 21, thereby realizing power transmission and ultimately driving the connecting rod 3 to rotate, controlling the extension and retraction of the limit sleeve 5. Limiting insert plates 9 are provided in the insertion grooves 8 opened around the surface of the mounting base plate 1 for inserting the mounting block 10. The counterweight plate 11 is installed on the mounting block 10. Under hard soil conditions, the counterweight plate 11 is placed directly on the mounting base plate 1, which significantly improves the overturning stability of the device by increasing the overall weight. Under softer soil conditions, the counterweight plate 11 is installed in the insertion grooves 8 around the mounting base plate 1 through the mounting block 10. By expanding the bottom bearing area and increasing the edge counterweight, the overall stability is further enhanced, preventing foundation settlement or lateral slippage.

[0041] The second connecting gear 19 and the third connecting gear 20 are not traditional cylindrical gears, but a pair of bevel gears (or bevel gears). Bevel gears are specifically designed to transmit motion and power between two intersecting axes (typically 90 degrees, but other angles are also possible). In this invention:

[0042] The second connecting gear 19 is driven by the first transmission rod 18, and its axis is generally horizontal.

[0043] The third connecting gear 20 is connected to the second transmission rod 21, and its axis is designed to be parallel to the tilt angle of the tilting rod 2.

[0044] The axes of these two gears intersect in space, perfectly meeting the application requirements of bevel gears. Through the meshing of these bevel gears, the horizontal rotational motion is successfully converted into a tilting rotational motion that matches the angle of the tilting rod 2.

[0045] Example 2:

[0046] This embodiment is basically the same as the previous embodiment, except that a support column 23 is installed on the top of the mounting base plate 1, a rotating bracket 24 is rotatably connected to the inner wall of the support column 23, a mounting bracket 25 is installed on the top of the rotating bracket 24, a connecting rod 26 is installed on one side of the rotating bracket 24, a second transmission gear 27 is installed on the surface of the connecting rod 26, a mounting sleeve 28 is installed on one side of the top of the support column 23, and the inner wall of the mounting sleeve 28 is fitted onto the surface of the second transmission gear 27. A handle 29 is rotatably connected to one side of the mounting sleeve 28, and a second transmission gear 27 is installed on one side of the handle 29. The second drive gear 30 has a connecting gear 31 meshing with its surface, and the surface of the connecting gear 31 meshes with the surface of the second transmission gear 27. A positioning tube 32 is installed on one side of the connecting gear 31, and a limiting tooth groove is formed on one side of the positioning tube 32. A pull rod 33 is inserted into the inner wall of the mounting box 28. Sliding blocks 34 are installed around the surface of the pull rod 33, and the surface of the sliding blocks 34 is slidably connected to the inner wall of the mounting box 28. A limiting plate 35 is installed at one end of the pull rod 33, and the surface of the limiting plate 35 is inserted into the inner wall of the limiting tooth groove.

[0047] In use, the main support is provided by the support column 23 fixed to the mounting base plate 1. The rotating bracket 24 rotatably connected to its inner wall can drive the top mounting bracket 25 to rotate, thereby realizing the direction adjustment of the photovoltaic panel. The connecting rod 26 installed on one side of the rotating bracket 24 is fixedly connected to the second transmission gear 27, which transmits the rotational motion to the inside of the mounting box 28. The handle 29 rotatably connected to one side of the mounting box 28 drives the second drive gear 30 to rotate. The second drive gear 30 meshes with the connecting gear 31, thereby driving the second transmission gear 27, which is coaxially connected to the connecting gear 31, to rotate. Finally, the rotating bracket 24 and the mounting bracket 25 are driven to rotate as a whole through the connecting rod 26. In order to lock the angle, a limiting tooth groove is opened on the positioning tube 32 on one side of the connecting gear 31. By pulling the pull rod 33 in the mounting box 28, the sliding block 34 on its surface ensures smooth movement, and the limiting plate 35 at its end is inserted into or released from the limiting tooth groove of the positioning tube 32, thereby realizing the fixing or release of the rotation angle, ensuring that the photovoltaic panel can be stably maintained in the required position after being adjusted.

[0048] Example 3:

[0049] This embodiment is basically the same as the previous embodiment, except that an assembly column 36 is installed on the inner wall of the support column 23, a connecting chain 37 is installed on the surface of the assembly column 36, a turnbuckle 38 is installed at the bottom end of the connecting chain 37, and an anchor rod 39 is installed at the bottom end of the turnbuckle 38.

[0050] In use, the upper connection point is provided by the assembly column 36 installed inside the support column 23. The lower end of the connecting chain 37 installed on the surface of the assembly column 36 is connected to the turnbuckle 38, and the bottom of the turnbuckle 38 is connected to the anchor rod 39. In use, the anchor rod 39 is driven into the geology of the hillside as a deep anchoring point. By rotating the turnbuckle 38, the length and tension of the connecting chain 37 can be precisely adjusted, thereby applying a prestress towards the slope to the support column 23 and the entire upper structure. This setting can effectively enhance the overall wind resistance and overturning stability of the device. Especially in steep or loose soil mountain environments, the deep fixation of the anchor rod 39 and the flexible connection of the turnbuckle 38 form a two-way constraint mechanism, which not only prevents the support device from tilting forward, but also avoids the overall displacement caused by foundation deformation, significantly improving the installation reliability and long-term safety of the photovoltaic array in mountain environments.

[0051] Application example:

[0052] In areas with complex terrain, varying slopes, and uneven soil structure—some areas having hard rock foundations while others are soft, sloping ground—traditional photovoltaic (PV) support systems struggle to adapt to such diverse terrain, exhibiting problems such as installation difficulties, insufficient stability, and weak wind resistance. To ensure the safe and stable operation of PV arrays under different slopes and geological conditions, this invention employs a terrain-adaptive adjustable support device for mountainous PV arrays.

[0053] At the project site, construction workers first conducted a terrain survey and site leveling of the area to be arranged for the photovoltaic array. The installation location of each support device was determined according to the design drawings. Installation work then commenced.

[0054] First, the basic fixing work is carried out. Construction workers place the mounting base plate 1 in the predetermined position and, using manpower or simple tools, insert the four inclined rods 2 into the hillside soil at a certain angle to achieve initial positioning of the device. In areas with harder geology, construction workers operate the handle 14 to rotate the drive rod 13, which in turn drives the first connecting gear 17 to rotate via the first drive gear 16. The power is transmitted through the first transmission rod 18 to the second connecting gears 19 at both ends, which in turn drive the third connecting gear 20 and the second transmission rod 21 to rotate. Finally, through the meshing of the fourth connecting gear 22 with the first transmission gear 7, the connecting rod 3 is rotated. The rotation of the connecting rod 3 causes the two opposing threaded rods 4 to rotate synchronously, pushing the limiting sleeve 5 outward along the threaded rods 4, gradually extending out of the surface of the inclined rods 2 and embedding into the surrounding hard soil or rock fissures, forming a reliable pull-out resistant structure. The positioning rod 6 ensures the stability of the threaded rods 4 during transmission. Under these geological conditions, the construction workers place the counterweight plate 11 directly on the upper surface of the mounting base plate 1. The extra weight of the counterweight plate significantly increases the overall mass and inertia of the device, effectively resisting wind loads and possible overturning moments, and enhancing stability.

[0055] In sloping areas with relatively soft soil, construction workers employed a different method for installing counterweights. They inserted the mounting block 10 into the interlocking slots 8 around the mounting base plate 1, and secured it with limiting plates 9. Then, multiple counterweight plates 11 were installed and fixed onto the mounting block 10. This circumferentially distributed counterweight method significantly increased the total weight at the bottom of the device. More importantly, it expanded the effective contact area between the device and the ground, distributing the concentrated load to a wider soil layer, thereby reducing the pressure on the foundation. This effectively prevented uneven settlement or overall slippage of the device under soft soil conditions, ensuring the long-term stability of the foundation.

[0056] After the foundation is fixed, the photovoltaic panel brackets are installed and their angles adjusted. The installers fix the mounting bracket 25 to the rotating bracket 24, and the photovoltaic modules are installed on the mounting bracket 25. When it is necessary to adjust the orientation of the photovoltaic panels to receive sunlight at the optimal angle, the installers first pull the lever 33 outwards. The lever 33 causes the limiting plate 35 at its end to overcome friction and disengage from the limiting groove of the positioning tube 32 (the sliding block 34 ensures the smooth movement of the lever 33), releasing the rotational lock on the connecting gear 31. Then, the handle 29 is turned, causing the second drive gear 30 to rotate. The second drive gear 30 drives the connecting gear 31, which in turn drives the second transmission gear 27, which meshes with the connecting gear 31, to rotate. The rotation of the second transmission gear 27 is transmitted through the connecting rod 26, ultimately driving the rotating bracket 24, along with the mounting bracket 25 and the photovoltaic modules, to rotate around the axis of the support column 23 to the predetermined optimal angle. After the angle is adjusted to the correct position, the construction workers push the pull rod 33 again, so that the limit plate 35 is accurately inserted into the current tooth groove of the positioning tube 32, thereby achieving mechanical locking of the rotation angle and ensuring that the photovoltaic panel can maintain a stable orientation under wind load or other external forces.

[0057] Finally, at installation points with extremely high stability requirements, such as steep slopes or windy areas, additional anchoring facilities were installed. Anchor rods 39 were driven at a certain angle into the solid rock or soil deep within the slope, forming deep anchoring points. Then, the length of the connecting chain 37 was finely adjusted by rotating the turnbuckle 38, tightening the chain and applying a continuous prestressing force pointing inwards towards the support column 23 through the mounting column 36. This prestressing effectively balances the overturning moment that the photovoltaic array might experience due to its own weight and wind pressure, greatly enhancing the wind resistance and overall stability of the entire support device, forming a rigid-flexible constraint system.

[0058] The terrain-adaptive adjustable support device for mountain photovoltaic arrays has successfully solved many problems in the construction of photovoltaic power stations in complex mountainous environments. It has achieved the goals of rapid adaptation to terrain, stable installation, flexible adjustment, and long-term reliable operation, ensuring the smooth construction of the mountain photovoltaic power station project and its subsequent stable power generation.

The connecting rod 3, rotatably connected inside the inclined rod 2, drives the limiting sleeve 5 through two opposing threaded rods 4 rotatably connected at its ends. When the connecting rod 3 rotates, the limiting sleeve 5 moves axially along the threaded rods 4 via threaded transmission, extending out from the surface of the inclined rod 2 and embedding into the surrounding soil, forming a pull-out resistant structure.
