Description

Technical Field

[0001] This invention belongs to the technical field of photovoltaic arrays, specifically, it relates to an adaptive erection device for photovoltaic arrays in mountainous ravines. Background Technology

[0002] Photovoltaic power generation has become the core direction of clean energy development. Complex terrains such as mountains, hills, and slopes account for more than 60% of the total land area. Photovoltaic development in these areas has huge potential, but there are also challenges such as shading caused by undulating terrain, significant differences in module tilt angles, and high transportation costs.

[0003] However, mountainous and ravine terrain is characterized by drastic changes in slope, irregular surface undulations, and complex geological conditions. Traditional photovoltaic support structures usually adopt fixed or simple adjustable structures, which are difficult to adapt to the spatial variation requirements of such terrain.

[0004] In related technologies, the piles of photovoltaic brackets are mostly rigid flat-bottomed structures, which cannot fit irregular slopes, resulting in a small contact area and insufficient grip. Under the action of external forces such as wind and rain, they are prone to slippage or overturning. At the same time, the spacing and angle of the front and rear piles of the bracket are fixed, and cannot be flexibly adjusted according to the actual slope of the gully terrain. This causes the photovoltaic panel installation angle to deviate from the optimal light-receiving direction, which seriously affects the power generation efficiency. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, embodiments of the present invention propose an adaptive erection device for photovoltaic arrays in mountainous ravines, which has the advantages of high erection efficiency and good stability.

[0007] The adaptive erection device for a photovoltaic array in mountainous ravines according to an embodiment of the present invention includes:

[0008] The frame includes a front anchoring pile frame and a rear adapting pile frame. The rear side of the front anchoring pile frame is connected to the rear adapting pile frame via a deflection frame. The deflection frame is locked by a locking component to lock the attitude after the frame is erected. The bottom side of the rear adapting pile frame is equipped with an adapting foot to help the rear adapting pile frame adapt to the slope of the mountain gully ground. An auxiliary fixing assembly includes a cylinder and a steel wire rope. A rotating shaft is rotatably connected to the center of the cylinder, and the cylinder is connected to the front anchoring pile frame via the rotating shaft. A winding wheel is connected to the end of the rotating shaft away from the front anchoring pile frame, and a spring is installed between the winding wheel and the cylinder. The middle end of the wire rope is crossed and wound around the outer wall of the winding reel. The two ends of the wire rope are folded into loops and fitted with embedded plugs. The overlapping part of the two ends of the wire rope is fixed by a clamping assembly. The wire rope is tightened and anchored on the ground with the embedded plugs. A photovoltaic panel pre-installation frame is used to install photovoltaic panels. Both ends of the bottom side of the photovoltaic panel pre-installation frame are provided with installation components. One end of the installation component is connected to the top side of the front anchoring pile frame, and the other end of the installation component is connected to the top of the rear adaptation pile frame through a vertically sliding lifting sleeve. The lifting sleeve is adjusted by the lifting component.

[0009] In some embodiments, the adaptive erection device for the mountainous ravine photovoltaic array of the present invention further includes a deflection frame and a limiting plug. The deflection frame includes a connecting rod. A first rotating seat is fixedly connected to the rear side of the front anchoring pile frame, and a second rotating seat is fixedly connected to the front side of the rear adaptive pile frame. The connecting rod is rotatably connected between the first rotating seat and the second rotating seat. A limiting tooth groove is formed at the front end of the connecting rod. One end of the limiting plug passes through the first rotating seat and abuts against the inside of the limiting tooth groove.

[0010] In some embodiments, the locking assembly includes a guide frame that slides vertically inside the front anchoring pile frame, a traction frame fixedly connected to the top of the guide frame, a rotating shaft that slides against a guide groove at the top of the traction frame via a guide protrusion, and the other end of the limiting plug that slides against a guide groove at the rear end of the guide frame.

[0011] In some embodiments, the adaptive erection device for the photovoltaic array in mountainous ravines according to the present invention further includes a retractable frame and a limiting column. The retractable frame includes two connecting rods, with a connecting sleeve rotatably connected to the adjacent side of the two connecting rods, and the opposite side of the two connecting rods rotatably connected to the rotating shaft. The limiting column is fixedly connected to the front middle part of the photovoltaic panel pre-installation frame, and the top side of the connecting rod is inserted into the bottom end of the limiting column through an insertion slot.

[0012] In some embodiments, the adaptive erection device for a mountainous ravine photovoltaic array of the present invention further includes a limiting component. The limiting component is connected between the outer wall of the rotating shaft and the winding wheel. The limiting component includes a locking inner shaft fixedly connected inside the cylinder. The interior of the locking inner shaft is slidably connected to two deflection limiting heads by springs. One end of the deflection limiting head is arc-shaped and abuts against a guide groove opened on the outer wall of the rotating shaft. The other end of the deflection limiting head is inserted into a slot on the inner circumference of the winding wheel.

[0013] In some embodiments, the clamping assembly includes a fixing sleeve disposed on the wire rope. One end of the fixing sleeve is slidably connected to a clamping plate, and one side of the fixing sleeve is rotatably connected to two clamping buckles. One end of each clamping buckle is provided with an arc-shaped abutment portion, and the other end of the clamping buckle is fixedly connected to a pre-locking ring. One end of the clamping buckle abuts against one side of the clamping plate through the arc-shaped abutment portion, and the other side of the clamping plate abuts against the wire rope through a concave-convex groove surface.

[0014] In some embodiments, the lifting assembly includes a screw fixedly connected to the top of the rear-adaptive pile frame, a screw sleeve rotatably connected to the inner center of the lifting sleeve, the screw sleeve being threaded onto the outer wall of the screw, and a force-applying groove provided on the top side of the screw sleeve to facilitate screwing.

[0015] In some embodiments, the installation assembly includes a plurality of snap-fit ​​seats fixedly connected to the bottom side of the photovoltaic panel pre-installation frame, a sliding frame fixedly connected to the front end of the lifting sleeve, a first snap-fit ​​buckle horizontally sliding on the top side of the sliding frame, a second snap-fit ​​buckle fixedly connected to the top side of the front anchoring pile frame, the snap-fit ​​seat located at the rear end of the photovoltaic panel pre-installation frame snapping into the inside of the first snap-fit ​​buckle, and the snap-fit ​​seat located at the front end of the photovoltaic panel pre-installation frame snapping into the inside of the second snap-fit ​​buckle.

[0016] In some embodiments, the adaptive foot includes an adaptive rubber pad fixedly connected to the bottom side of the rear adaptive pile frame. The adaptive rubber pad is hoof-shaped, hollow inside and provided with multiple mutually abutting extrusion protrusions, and the bottom side of the adaptive rubber pad is provided with concave and convex textures.

[0017] In some embodiments, the adaptive erection device for the mountainous ravine photovoltaic array of the present invention further includes an embedded shaft core sleeved on the bottom side of the front anchoring pile frame, the embedded shaft core being used to be buried in a pre-opened foundation pit and sealed with cement.

[0018] This invention provides an adaptive installation device for photovoltaic arrays in mountainous ravines. It has the following beneficial effects: 1. This invention provides a hoof-shaped adaptive rubber pad on the bottom side of the post-adaptive pile frame. Utilizing its internal hollow structure and multiple mutually abutting extrusion protrusions, the rubber pad can adaptively deform along irregular slopes when subjected to the weight of the pile frame and ground reaction forces. The extrusion protrusions automatically fill the depressions on the slope, and the bottom texture maximizes the contact area, thereby significantly increasing grip and friction. This effectively solves the problem that traditional rigid pile feet cannot conform to irregular slopes, ensuring stable support of the post-adaptive pile frame on gully slopes and avoiding the risk of slippage or overturning due to terrain undulations.

[0019] 2. This invention utilizes the rotation of the connecting rod between rotating seat one and rotating seat two to achieve adjustment of the angle and position of the rear adaptive pile frame relative to the front anchor pile frame. The rotation of the rotating shaft drives the linkage displacement of the traction frame, guide frame, and limit plug, so that the limit plug is precisely inserted into the limit tooth groove at the front end of the connecting rod, achieving reliable locking of the deflection frame posture. This design allows the relative angle of the front and rear pile frames to be flexibly adjusted according to the actual slope of the gully. After adjustment, it can be locked with one click, taking into account both terrain adaptability and structural rigidity, and overcoming the defect of traditional fixed supports that cannot adapt to slope changes.

[0020] 3. This invention can flexibly switch between the stored state and the unfolded state, which is convenient for transportation and rapid on-site deployment. By pulling the clamping buckle, the arc-shaped abutment part is offset and pushes against the clamping plate. The concave and convex grooves bite the steel wire rope to achieve high-strength fixation. This anchoring system can quickly establish tension anchoring points in mountainous gullies, forming a double anchoring with the cement sealing of the embedded shaft core on the bottom side of the front anchoring pile frame.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1-19As shown, the adaptive mounting device for a mountainous ravine photovoltaic array according to an embodiment of the present invention includes: a frame, auxiliary fixing components, and a photovoltaic panel pre-mounting frame 22.

[0025] The frame includes a front anchoring pile frame 1 and a rear adapting pile frame 2. The rear side of the front anchoring pile frame 1 is connected to the rear adapting pile frame 2 via a deflection frame. The deflection frame is locked by a locking component to lock the attitude after the frame is erected. The bottom side of the rear adapting pile frame 2 is equipped with an adapting foot to help the rear adapting pile frame 2 adapt to the slope of the mountain gully ground.

[0026] The auxiliary fixing component includes a cylinder 4 and a steel wire rope 16. A rotating shaft 11 is rotatably connected to the center of the cylinder 4. The cylinder 4 is connected to the front anchoring pile frame 1 through the rotating shaft 11. A winding wheel 12 is connected to the end of the rotating shaft 11 away from the front anchoring pile frame 1. A spring is installed between the winding wheel 12 and the cylinder 4. The middle end of the steel wire rope 16 is crossed and wound on the outer wall of the winding wheel 12. The two ends of the steel wire rope 16 are folded into loops and fitted with embedded plugs 21. The overlapping part of the two ends of the steel wire rope 16 is fixed by a clamping component. The steel wire rope 16 is tightened and anchored on the ground with the embedded plugs 21.

[0027] The photovoltaic panel pre-installation frame 22 is used to install photovoltaic panels. Both ends of the bottom side of the photovoltaic panel pre-installation frame 22 are equipped with installation components. One end of the installation component is connected to the top side of the front anchor pile frame 1, and the other end of the installation component is connected to the top of the rear adaptation pile frame 2 through a vertically sliding lifting sleeve 25. The lifting sleeve 25 is adjusted by the lifting component.

[0028] like Figure 1 , Figure 3 and Figure 19 As shown, the frame includes two front anchor pile frames 1 and two rear adapting pile frames 2. The rear adapting pile frames 2 are connected to the rear of the front anchor pile frames 1 via deflection frames. The deflection frames are locked by the locking component transmission limit plug 6 to lock the attitude after the frame is erected. The rear adapting pile frames 2 are equipped with adapting feet on the bottom to help the rear adapting pile frames 2 adapt to the slope of the mountain gully ground. The embedded shaft core 33, which is sleeved on the bottom of the front anchor pile frames 1, is used to be buried in the pre-opened foundation pit and sealed with cement. Specifically, standard anchor points need to be established on the same straight line according to the measurement distance. Based on the position of the standard anchor points, pits are dug, the embedded shaft core 33 is placed into the pits, and sufficient cement is poured into the pits. The standard anchor points cannot be changed. In order to maintain the normal operation of the photovoltaic panels, the area of ​​the photovoltaic panels cannot be changed arbitrarily. Only one set of points is set as the quantitative basis of the process, which serves as a favorable support condition for subsequent variable adaptation. Without setting a quantitative basis, too many variables will excessively waste the available area of ​​the photovoltaic array in the mountainous ravines. With the aid of a stable support frame, wait for the embedded shaft core 33 to be firmly sealed in cement. Then, unfold the front anchoring pile frame 1 and the rear adapting pile frame 2 on both sides. During the unfolding process, the two connecting rods 23 rotate on the connecting sleeve 24 and the rotating shaft 11 respectively. After being fully unfolded, they are in a horizontal position. Figure 2 It is in storage state.

[0029] like Figures 6-8 As shown, there are two cylinders 4, which are fixedly connected to the two front anchoring piles 1 on the same side. A rotating shaft 11 is rotatably connected to the center of the cylinder 4. A take-up frame is installed on the side of the rotating shaft 11 on both sides that are close to each other. The side of the rotating shaft 11 on both sides that are far apart is connected to a locking component. A winding wheel 12 is connected to the outer wall of the side of the rotating shaft 11 on both sides through a limiting component. A spring is installed between the winding wheel 12 and the cylinder 4.

[0030] like Figure 3 , Figure 6 and Figure 11 As shown, the middle end of the wire rope 16 is crossed and wound around the outer wall of the winding wheel 12. The two ends of the wire rope 16 are folded into loops and fitted with embedded plugs 21. The overlapping part of the two ends of the wire rope 16 is fixed by a clamping assembly. The wire rope 16 is tightened and anchored on the ground with the embedded plugs 21 to improve the firmness and stability of the front anchoring pile frame 1.

[0031] In some embodiments, the adaptive erection device for the mountainous ravine photovoltaic array of the present invention further includes a deflection frame and a limiting plug 6. The deflection frame includes a connecting rod 3. A first rotating seat 8 is fixedly connected to the rear side of the front anchoring pile frame 1, and a second rotating seat 9 is fixedly connected to the front side of the rear adaptive pile frame 2. The connecting rod 3 is rotatably connected between the first rotating seat 8 and the second rotating seat 9. A limiting tooth groove 7 is opened at the front end of the connecting rod 3. One end of the limiting plug 6 passes through the first rotating seat 8 and abuts against the inside of the limiting tooth groove 7.

[0032] like Figures 3-5 As shown, specifically, the bottom end of the front anchoring pile frame 1 is first inserted into the embedded shaft core 33 as a reference anchor point. Then, the rear adapting pile frame 2 is pulled backward, causing the connecting rod 3 to deflect on the first rotating seat 8 and the second rotating seat 9, so that the relative position of the rear adapting pile frame 2 and the front anchoring pile frame 1 changes until the adapting rubber pad 31 at the bottom end of the rear adapting pile frame 2 is placed on the irregular ground of the mountain gully. Due to the terrain, a slope will be generated here, and the adapting rubber pad 31 at the bottom end of the rear adapting pile frame 2 is placed on the irregular slope.

[0033] In some embodiments, the locking assembly includes a guide frame 5 that slides vertically inside the front anchoring pile frame 1, a traction frame 10 that is fixedly connected to the top of the guide frame 5, a rotating shaft 11 that slides against the guide groove at the top of the traction frame 10 via a guide protrusion, and the other end of the limiting plug 6 that slides against the guide groove at the rear end of the guide frame 5.

[0034] like Figures 3-5 As shown, after the position of the post-adaptive pile frame 2 is stabilized, the structure including the connecting rod 23 and the rotating shaft 11 is twisted to rotate it by 90°, so that the insertion groove on the connecting rod 23 faces upward. The rotating shaft 11 sequentially drives the traction frame 10 to move through the guide groove and offsets and abuts against the deflection limiting head 14 through the guide groove 15. After the displacement, the traction frame 10 drives the bottom guide frame 5 to move upward, so that the guide groove on the guide frame 5 drives the limiting plug 6 to move, so that the end of the limiting plug 6 is inserted into the limiting tooth groove 7 at the end of the connecting rod 3, thereby limiting the angle of the connecting rod 3.

[0035] In some embodiments, the adaptive installation device for the mountainous ravine photovoltaic array of the present invention further includes a retractable frame and a limiting post 30. The retractable frame includes two connecting rods 23. A connecting sleeve 24 is rotatably connected to the adjacent side of the two connecting rods 23. The opposite side of the two connecting rods 23 is rotatably connected to the rotating shaft 11. The limiting post 30 is fixedly connected to the front middle part of the photovoltaic panel pre-installation frame 22. The top side of the connecting rod 23 is inserted into the bottom end of the limiting post 30 through an insertion slot.

[0036] like Figure 1 As shown, the folding frame automatically locks when extended to a predetermined angle via the insertion of the limiting post 30 and the insertion slot, eliminating the need for additional locking operations and improving installation efficiency. The two connecting rods 23 are rotatably connected via the connecting sleeve 24, forming a four-bar linkage (or scissor structure). This allows the two connecting rods 23 to swing symmetrically relative to the rotating shaft 11, ensuring balanced force on the left and right sides of the photovoltaic panel pre-installation frame 22 and preventing tilting due to uneven loading. The folding frame can be folded (in transport mode) and extended (in working mode). The limiting post 30 limits the maximum opening after extension, preventing excessive opening and structural instability. It adapts to irregular ground while ensuring the flatness of the photovoltaic panel array.

[0037] In some embodiments, the adaptive erection device for the mountainous ravine photovoltaic array of the present invention further includes a limiting component. The limiting component is connected between the outer wall of the rotating shaft 11 and the winding wheel 12. The limiting component includes a locking inner shaft 13 fixedly connected inside the cylinder 4. The interior of the locking inner shaft 13 is slidably connected to two deflection limiting heads 14 by springs. One end of the deflection limiting head 14 is arc-shaped and abuts against the guide groove 15 opened on the outer wall of the rotating shaft 11. The other end of the deflection limiting head 14 is inserted into the slot on the inner circumference of the winding wheel 12.

[0038] like Figures 8-10 As shown, specifically, the deflection limiting head 14 deflects along the curved surface of the guide groove 15 area, causing the maximum diameter surface of the rotating shaft 11 to abut against the guide groove 15, and causing the deflection limiting head 14 to shift so that its end is inserted into the slot of the winding wheel 12, thereby limiting the winding wheel 12 and preventing the winding wheel 12 from pulling the wire rope 16.

[0039] In some embodiments, the clamping assembly includes a fixing sleeve 17 disposed on the wire rope 16. One end of the fixing sleeve 17 is slidably connected to a clamping piece 18. Two clamping buckles 19 are rotatably connected to one side of the fixing sleeve 17. One end of the clamping buckle 19 is provided with an arc-shaped abutment portion. The other end of the clamping buckle 19 is fixedly connected to a pre-locking ring 20. One end of the clamping buckle 19 abuts against one side of the clamping piece 18 through the arc-shaped abutment portion. The other side of the clamping piece 18 abuts against the wire rope 16 through a concave-convex groove surface.

[0040] like Figures 11-13 As shown, specifically, pulling the wire rope 16 causes the winding wheel 12 wound around the wire rope 16 to rotate, causing both ends of the wire rope 16 wound on the winding wheel 12 to lengthen, and move together with the structure including the fixing sleeve 17 and the embedded plug 21, until it is pulled to the limit distance, and the embedded plug 21 is inserted into the ground at the limit distance. Then, pulling the end of the wire rope 16 causes the wire rope 16 to partially displace and lengthen through the fixing sleeve 17, thereby increasing the tension of the wire rope 16.

[0041] Then, pulling the clamping buckle 19 causes the arc-shaped contact area of ​​the clamping buckle 19 to shift and come into contact with the clamping plate 18, causing the clamping plate 18 to shift and the concave and convex surfaces of the clamping plate 18 to bite the rope part of the wire rope 16 for fixation. The two traction frames 10 on the clamping buckle 19 are locked by inserting bolts, safety bolts and other fixing methods to form double anchoring, which greatly enhances the pull-out resistance and overturning resistance of the front anchoring pile frame 1 under soft or inclined geological conditions.

[0042] In some embodiments, the lifting assembly includes a screw 34 fixedly connected to the top of the rear adaptation pile frame 2, a screw sleeve 35 rotatably connected to the inner center of the lifting sleeve 25, the screw sleeve 35 being threadedly connected to the outer wall of the screw 34, and a force-applying groove provided on the top side of the screw sleeve 35 to facilitate turning the screw sleeve 35.

[0043] like Figure 15 and Figure 16 As shown, the rear-adaptive pile frame 2 and the lifting sleeve 25 are driven by the screw of the threaded pair, which converts the rotational motion into linear motion. The thread has a self-locking characteristic (generally, a single-threaded thread is self-locking when there is no vibration), which allows the lifting sleeve 25 to stay at any height without sliding down due to its own weight.

[0044] In some embodiments, the installation assembly includes a plurality of snap-fit ​​seats 29 fixedly connected to the bottom side of the photovoltaic panel pre-installation frame 22, a sliding frame 26 fixedly connected to the front end of the lifting sleeve 25, a first snap-fit ​​buckle 27 horizontally sliding on the top side of the sliding frame 26, a second snap-fit ​​buckle 28 fixedly connected to the top side of the front anchoring pile frame 1, a snap-fit ​​seat 29 located at the rear end of the photovoltaic panel pre-installation frame 22 snaps into the inside of the first snap-fit ​​buckle 27, and a snap-fit ​​seat 29 located at the front end of the photovoltaic panel pre-installation frame 22 snaps into the inside of the second snap-fit ​​buckle 28.

[0045] like Figures 14-16 As shown, specifically, after the frame is stabilized, the force groove on the top side of the screw sleeve 35 on the lifting sleeve 25 is turned to make the screw sleeve 35 rotate, causing it to rotate on the screw rod 34. This allows the lifting sleeve 25 to adjust its height along with the screw sleeve 35. The infantry then adjusts the position of the first snap fastener 27 on the sliding frame 26 so that the two adjacent sets of first snap fasteners 27 and second snap fasteners 28 are on overlapping diagonal lines. When the two adjacent rear-adaptive pile frames 2 are on irregular slopes, the installation point at the top of the rear-adaptive pile frame 2 can be adjusted to adapt to the influence of irregular slopes and overcome the environmental influence of mountain gullies. Finally, the snap fasteners 29 on the bottom side of the photovoltaic panel pre-installation frame 22 are sequentially snapped onto the first snap fasteners 27 and the second snap fasteners 28. The limiting post 30 is inserted into the insertion slot of the connecting rod 23 to restrict the rotation of the connecting rod 23 and its rotating shaft 11. Finally, the photovoltaic panel is installed on the photovoltaic panel pre-installation frame 22, thus completing the installation.

[0046] In some embodiments, the adapting foot includes an adapting pad 31 fixedly connected to the bottom side of the rear adapting pile frame 2. The adapting pad 31 is hoof-shaped, and its interior is hollowed out and provided with a plurality of mutually abutting extrusion protrusions 32. The bottom side of the adapting pad 31 is provided with concave and convex textures.

[0047] like Figure 3 , Figure 17 and Figure 18 As shown, the adapting foot includes an adapting rubber pad 31 fixedly connected to the bottom side of the rear adapting pile frame 2. The adapting rubber pad 31 is hoof-shaped, hollow inside, and has multiple mutually abutting extrusion protrusions 32. The bottom side of the adapting rubber pad 31 is provided with concave and convex textures.

[0048] Specifically, the hoof-shaped design of the adaptable pad 31 is based on the hoof of a ibex. The ibex hoof maximizes the contact area with the slope surface by branching the hoof when facing rugged and stable slopes, and maintains stable friction. The deformation it undergoes also helps to improve its adaptability to irregular slopes.

[0049] The hollow and extruded protrusions 32 of the adaptable pad 31 are used to simulate the adaptable pad 31 contacting the ground on an irregular slope. By extruding and filling the redundant space, the adaptable pad 31 is shaped to fit the irregular slope, so as to maintain the maximum contact area.

[0050] The adapting rubber pad 31 at the bottom of the rear adapting pile frame 2 is placed on the irregular ground of the mountain gully. Due to the terrain, a slope will be formed here, and the adapting rubber pad 31 at the bottom of the rear adapting pile frame 2 is placed on the irregular slope. Due to the weight of the rear adapting pile frame 2 on the top side, the adapting rubber pad 31 is subjected to double compression from the ground and the rear adapting pile frame 2. The adapting rubber pad 31 deforms along the irregular slope, and the internal compression protrusions 32 fill into the corresponding idle areas, dynamically adapting to the irregular slope, so that the bottom side of the adapting rubber pad 31 always has maximum contact with the slope, providing sufficient grip and friction.

[0051] In some embodiments, the adaptive erection device for the mountainous ravine photovoltaic array of the present invention further includes an embedded shaft core 33 sleeved on the bottom side of the front anchoring pile frame 1. The embedded shaft core 33 is used to be buried in a pre-opened foundation pit and sealed with cement.

[0052] like Figure 1 and Figure 19 As shown, specifically, the embedded shaft core 33 is a hollow cylindrical structure, that is, multiple through holes are opened on the outer peripheral wall of the embedded shaft core 33 so that when cement is sealed, cement can flow into the interior of the embedded shaft core 33 through multiple through holes, thereby making the overall stability of the embedded shaft core 33 better after the cement solidifies.

[0053] In summary, the present invention provides an adaptive erection device for photovoltaic arrays in mountainous ravines, which has the following beneficial effects: 1. This invention provides a hoof-shaped adaptive rubber pad on the bottom side of the post-adaptive pile frame. Utilizing its internal hollow structure and multiple mutually abutting extrusion protrusions, the rubber pad can adaptively deform along irregular slopes when subjected to the weight of the pile frame and ground reaction forces. The extrusion protrusions automatically fill the depressions on the slope, and the bottom texture maximizes the contact area, thereby significantly increasing grip and friction. This effectively solves the problem that traditional rigid pile feet cannot conform to irregular slopes, ensuring stable support of the post-adaptive pile frame on gully slopes and avoiding the risk of slippage or overturning due to terrain undulations.

[0054] 2. This invention utilizes the rotation of the connecting rod between rotating seat one and rotating seat two to achieve adjustment of the angle and position of the rear adaptive pile frame relative to the front anchor pile frame. The rotation of the rotating shaft drives the linkage displacement of the traction frame, guide frame, and limit plug, so that the limit plug is precisely inserted into the limit tooth groove at the front end of the connecting rod, achieving reliable locking of the deflection frame posture. This design allows the relative angle of the front and rear pile frames to be flexibly adjusted according to the actual slope of the gully. After adjustment, it can be locked with one click, taking into account both terrain adaptability and structural rigidity, and overcoming the defect of traditional fixed supports that cannot adapt to slope changes.

[0055] 3. This invention can flexibly switch between the stored state and the unfolded state, which is convenient for transportation and rapid on-site deployment. By pulling the clamping buckle, the arc-shaped abutment part is offset and pushes against the clamping plate. The concave and convex grooves bite the steel wire rope to achieve high-strength fixation. This anchoring system can quickly establish tension anchoring points in mountainous gullies, forming a double anchoring with the cement sealing of the embedded shaft core on the bottom side of the front anchoring pile frame.
