Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to an adjustable photovoltaic array support device suitable for complex terrain. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic power generation, as an important component of green renewable energy, has seen its industry scale continue to expand. In order to obtain more abundant solar resources, the construction of photovoltaic power plants has gradually expanded from flat areas to complex terrains such as mountains, hills, deserts, and Gobi. Therefore, adjustable photovoltaic support equipment suitable for complex terrains is needed.

[0003] Existing photovoltaic panel support frames are unable to achieve shock absorption and damping effects under long-term wind exposure, which can lead to resonance of the photovoltaic panels under instantaneous natural frequency vibration, thus increasing the risk of cracking the photovoltaic panels.

[0004] The existing patent (publication number: CN221886353U) discloses a photovoltaic panel support device. This device can play a role in shock absorption and damping of the support frame, effectively reducing the resonance amplitude, thereby achieving better vibration reduction and solving the problem that photovoltaic panels are easily damaged by resonance and cracked.

[0005] To address the aforementioned issues, existing patents offer solutions. However, when installing photovoltaic panels on complex terrain with varying elevations, existing methods require the use of cement bases to adjust the height of each photovoltaic support, ensuring that the photovoltaic panels are installed at a uniform level. This method necessitates leveling the land and pouring foundations point by point according to the terrain, resulting in high labor input, long construction periods, and high material costs. Excavating multiple cement bases can easily damage vegetation, disturb the soil, and cause significant damage to the ecological environment.

[0006] To address this, an adjustable photovoltaic array support device suitable for complex terrain is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable photovoltaic array support device suitable for complex terrain. This device solves the problem that existing photovoltaic installation methods, when installing photovoltaic panels on most complex terrains with varying elevations, require the use of cement bases to adjust the height of each photovoltaic support to ensure that the photovoltaic panels are installed at a uniform level. This method requires leveling the land and pouring foundations point by point according to the terrain, which involves a large labor input, a long construction period, and high material costs. Excavating multiple cement bases can easily damage vegetation, disturb the soil, and cause significant damage to the ecological environment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an adjustable photovoltaic array support device suitable for complex terrain, comprising a connecting rod, with pillars provided on both sides of the bottom of the connecting rod, an adjustment mechanism provided at the bottom of the connecting rod, the number of adjustment mechanisms being several, and a support mechanism provided at the bottom of the adjustment mechanism;

[0009] The support mechanism includes two throttles, a support plate, a bubble level, and a spiral drill rod. The throttles are rotatably connected to the top of the support plate, the bubble level is embedded inside the support plate, and the top of the spiral drill rod is fixedly connected to the bottom of the support plate.

[0010] Preferably, the adjustment mechanism includes a mounting frame, a sliding sleeve, an adjustment column, several limiting holes, and a fixing column. The bottom of the mounting frame is fixedly connected to the top of the sliding sleeve. The sliding sleeve is disposed on the top of the adjustment column. The bottom of the adjustment column extends into the interior of the fixing column and makes movable contact with the interior of the fixing column. The limiting holes are opened on the front side of the adjustment column.

[0011] Preferably, a limit button is provided on the front side of the fixing post, the rear side of the limit button passes through the fixing post and extends into the interior of the limit hole, and the surface of the limit button is threadedly connected to the interior of the fixing post.

[0012] Preferably, pull blocks are fixedly connected to both sides of the adjusting column, and a rotating shaft is movably arranged inside the sliding sleeve. The bottom of the rotating shaft is fixedly connected to the top of the adjusting column, and the sliding sleeve is rotatably connected to the top of the adjusting column through the rotating shaft.

[0013] Preferably, a connecting plate is fixedly connected to the bottom of the fixed column, and the connecting plate has four connecting holes evenly distributed inside the connecting plate. A stud that mates with the connecting holes is fixedly connected to the top of the support plate. The stud passes through the connecting hole and extends to the outside of the connecting hole. Two nuts are provided on the top of the stud, and the nuts are threaded onto the surface of the stud.

[0014] Preferably, the sliding sleeve is slidably fitted onto the surface of the connecting rod, and a connecting groove is provided inside the support column, with the surface of the connecting rod contacting the inner wall of the connecting groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a support mechanism, this application allows the user to hold the handle and observe the bubble level. The spiral rod is then drilled horizontally into the ground to keep the support plate horizontal. The connecting plate is then connected to the support plate through the connecting hole, two nuts, and studs. At this time, the top of the mounting frame will also be horizontal, which facilitates the subsequent installation of photovoltaic panels at the same height and in a neat manner.

[0019] 2. This application, by setting an adjustment mechanism, allows for height adjustment of the adjustment column, and then fine-tuning of the height of the mounting frame by rotating the auger drill rod. This ensures that multiple sliding sleeves and the mounting frame can maintain the same height. Then, multiple sliding sleeves are rotated to the same angle and connected in series using connecting rods to form an array. Finally, the support column and connecting rod are stably connected with screws. Only two cement foundation piles are needed to stably support the support column and connection. This allows for the uniform and orderly installation of multiple photovoltaic panels at the same height in complex terrain with varying elevations, significantly reducing labor and construction costs and environmental damage.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] An adjustable photovoltaic array support device suitable for complex terrain includes a connecting rod 1, with support columns 2 on both sides of the bottom of the connecting rod 1, an adjustment mechanism 4 at the bottom of the connecting rod 1, and several adjustment mechanisms 4, with a support mechanism 3 at the bottom of the adjustment mechanism 4.

[0031] The support mechanism 3 includes two throttles 301, a support plate 302, a bubble level 303, and a spiral drill rod 304. The throttles 301 are rotatably connected to the top of the support plate 302, the bubble level 303 is embedded inside the support plate 302, and the top of the spiral drill rod 304 is fixedly connected to the bottom of the support plate 302.

[0032] In this embodiment: When installing photovoltaic panels on complex terrain, the support mechanism 3 is first placed at a predetermined position. The construction worker holds the handle 301 and drills into the spiral drill rod 304. Adjusting according to the bubble level 303, the support plate 302 is fixed horizontally. Then, the connecting plate 5 is tightly connected to the support plate 302 through the stud 10 and double nuts 9, driving the top of the mounting frame 401 to a horizontal state. Next, the adjusting column 403 pull block 8 is held, and the height of the sliding sleeve 402 is adjusted by its sliding within the fixed column 405 and fixed by the limit button 7. If it is restricted by the limit hole 404, the handle 301 can be rotated to finely adjust the height of the support plate 302 and the sliding sleeve 402. Then, the sliding sleeve 402 and the mounting frame 401 are rotated to the same angle. Multiple sliding sleeves 402 are connected in series by the connecting rod 1 to restrict the sliding sleeves 402 and the mounting frame 401. Rotation arranges the mounting brackets 401 into a matrix distribution. Two cement piles are constructed to fix the support pillars 2. The positioning plate 12 is connected to the cement base via external bolts, and the connecting rod 1 is securely connected to the support pillar 2 via screws 13. Only two cement bases are needed to install multiple photovoltaic panels at the same height on complex terrain with varying elevations. This significantly reduces labor costs and environmental damage. It solves the problem that existing methods for installing photovoltaic panels on most complex terrains with varying elevations require the use of cement bases to adjust the height of each photovoltaic support to ensure that the photovoltaic panels are installed at a uniform level. This method requires leveling the land and pouring the bases point by point according to the terrain, which involves a large labor input, a long construction period, and high material costs. Excavating multiple cement base foundations can easily damage vegetation, disturb the soil, and cause significant damage to the ecological environment.

[0033] Specifically, such as Figure 3 As shown, the adjustment mechanism 4 includes a mounting bracket 401, a sliding sleeve 402, an adjustment column 403, several limiting holes 404, and a fixing column 405. The bottom of the mounting bracket 401 is fixedly connected to the top of the sliding sleeve 402. The sliding sleeve 402 is located on the top of the adjustment column 403. The bottom of the adjustment column 403 extends into the interior of the fixing column 405 and makes movable contact with the interior of the fixing column 405. The limiting holes 404 are opened on the front side of the adjustment column 403.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, a limit button 7 is provided on the front side of the fixing post 405. The rear side of the limit button 7 passes through the fixing post 405 and extends into the interior of the limit hole 404. The surface of the limit button 7 is threadedly connected to the interior of the fixing post 405.

[0035] Specifically, such as Figure 3 As shown, pull blocks 8 are fixedly connected to both sides of the adjusting column 403, and a rotating shaft 14 is movably arranged inside the sliding sleeve 402. The bottom of the rotating shaft 14 is fixedly connected to the top of the adjusting column 403, and the sliding sleeve 402 is rotatably connected to the top of the adjusting column 403 through the rotating shaft 14.

[0036] In this embodiment: by adjusting the height of the adjusting column 403 and then fine-tuning it by rotating the auger drill rod 304, multiple sliding sleeves 402 can be adjusted to the same height, facilitating subsequent series connection using the connecting rod 1, so that the mounting brackets 401 form an array. After adjusting the adjusting column 403, the adjusting column 403 is limited by rotating the limit button 7 into the limit hole 404. The adjusting column 403 can be easily moved by pulling the pull block 8. The sliding sleeve 402 is rotatably connected to the adjusting column 403 through the rotating shaft 14. No matter where the auger drill rod 304, connecting plate 5, fixed column 405 and adjusting column 403 are rotated, the sliding sleeve 402 and the mounting bracket 401 can be rotated to the same position, facilitating the connection rod 1 to pass through the gap between the rotating shaft 14 and the sliding sleeve 402, restricting the rotation of the sliding sleeve 402 and the mounting bracket 401, facilitating the subsequent installation of photovoltaic panels at the same height and in a neat manner.

[0037] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, a connecting plate 5 is fixedly connected to the bottom of the fixed column 405. The connecting plate 5 has four connecting holes 6 inside, which are evenly distributed inside the connecting plate 5. A stud 10 that mates with the connecting hole 6 is fixedly connected to the top of the support plate 302. The stud 10 passes through the connecting hole 6 and extends to the outside of the connecting hole 6. Two nuts 9 are provided on the top of the stud 10. The nuts 9 are threaded onto the surface of the stud 10.

[0038] Specifically, such as Figure 1 and Figure 5 As shown, the sliding sleeve 402 is slidably sleeved on the surface of the connecting rod 1, and the support column 2 has a connecting groove 11 inside, with the surface of the connecting rod 1 in contact with the inner wall of the connecting groove 11.

[0039] In this embodiment: After observing the bubble level 303 to rotate the auger rod 304 horizontally to the ground, the connecting plate 5 is aligned with the studs 10 on the top of the support plate 302 through the four connecting holes 6. Then, two nuts 9 are threaded onto the studs 10 extending out of the connecting holes 6. By tightening the nuts 9, the two nuts 9 make the connection between the connecting plate 5 and the support plate 302 tighter, thus limiting the mounting frame 401 to a horizontal state at the top. The photovoltaic panels are then installed at the top in a regular and uniform manner. The connecting rod 1 passes through multiple sliding sleeves 402 to connect the mounting frame 401 in series to the array distribution. By contacting the connecting rod 1 with the connecting groove 11, the support column 2 can stably support the connecting rod 1, thereby making the state of the sliding sleeves 402 and the mounting frame 401 more stable.

[0040] Specifically, such as Figure 1 and Figure 5As shown, screws 13 are provided on both sides of the front side of the support column 2. The rear side of the screws 13 passes through the support column 2 and the connecting rod 1 in sequence and extends to the outside of the support column 2. The surface of the screws 13 is connected to the internal thread of the connecting rod 1.

[0041] Specifically, such as Figure 5 As shown, a positioning plate 12 is fixedly connected to the bottom of the support column 2.

[0042] In this embodiment: by passing screw 13 through the support column 2 and the connecting rod 1 and locking it, the connecting rod 1 can be connected to the support column 2. By constructing two cement foundation piles at the corresponding positions of the positioning plate 12 and fixing the support column 2 through the positioning plate 12 with external bolts, the support column 2 can provide stable support for the connecting rod 1.

[0043] Working Principle: When installing photovoltaic panels on complex, undulating terrain, the support mechanism 3 is first placed at the predetermined installation point. The worker holds the handle 301 with both hands. The rotating connection between the handle 301 and the support plate 302 facilitates the rotation of the support plate 302, thereby driving the spiral drill rod 304, which is fixedly connected to the bottom of the support plate 302, to drill into the ground. During this process, the worker must constantly observe the bubble level 303 embedded inside the support plate 302. The position of the bubble indicates the horizontal state of the support plate 302. When the bubble is in the center of the level, it indicates that the support plate 302 is horizontal, and the spiral drill rod 304 has been firmly drilled into the ground. This connects to the plate 5, fixed column 405, adjusting column 403, and sliding sleeve 4. 02 and mounting bracket 401 provide a horizontal foundation. Then, the connecting plate 5 is aligned with the studs 10 on the top of the support plate 302 through the four connecting holes 6. Subsequently, two nuts 9 are threaded onto the studs 10 extending outside the connecting holes 6. By tightening the nuts 9, the double nuts 9 make the connection between the connecting plate 5 and the support plate 302 tighter. At this time, the mounting bracket 401 connected to the sliding sleeve 402 is also in a horizontal state along with the support plate 302. Then, the construction personnel hold the pull blocks 8 on both sides of the adjusting column 403 with both hands and pull the adjusting column 403 up or down according to the actual terrain height difference. The adjusting column 403 slides inside the fixed column 405. When the adjusting column 403 is adjusted to a suitable height, so that the sliding sleeve 402 is at the same height as the adjacent sliding sleeve 402, Turn the limiting button 7 on the front side of the fixed column 405 backward. The limiting button 7 passes through the fixed column 405 and screws into the corresponding limiting hole 404 on the front side of the adjusting column 403. The position of the adjusting column 403 is fixed by the threaded connection. If the sliding sleeve 402 cannot be adjusted to the ideal height by adjusting the adjusting column 403 due to the gap between the limiting holes 404, the construction worker can hold the handle 301 again and turn the support plate 302 slightly to drive the spiral drill rod 304 to make fine adjustments on the ground, thereby achieving fine adjustment of the height of the support plate 302 and the sliding sleeve 402. Then, rotate the sliding sleeve 402 and the mounting bracket 401 to the same angle, and use the connecting rod 1 to pass through the gap between the rotating shaft 14 and the sliding sleeve 402 to connect multiple sliding sleeves 402 together, limiting the sliding sleeve 402. The rotation of 02 and mounting bracket 401 causes the mounting bracket 401 to be arranged in an array. The sliding sleeve 402 is rotatably connected to the adjusting column 403 through the rotating shaft 14, allowing the sliding sleeve 402 to rotate. At this time, the positioning plate 12 at the bottom of the support column 2 is placed in the selected position. Two cement foundation piles are built at the corresponding positions of the positioning plate 12. External bolts are used to pass through the positioning plate 12 to fix the support column 2. Then, the two ends of the connecting rod 1 are embedded into the connecting groove 11 inside the support column 2, and screws 13 are used to pass through the support column 2 and the connecting rod 1 in sequence and tighten them, so that the support column 2 provides stable support for the connecting rod 1. The connecting rod 1 and the support column 2 can further stabilize and restrict the rotation of multiple sliding sleeves 402 and mounting bracket 401. Finally, since the mounting bracket 401 is set at an angle,Construction workers can directly and neatly fix multiple photovoltaic panels at the same height on top of the mounting frame 401. The installation of multiple photovoltaic panels requires only two cement bases to fix the support pillars 2. Furthermore, by adjusting the height of the adjusting column 403 and the auger drill rod 304, the photovoltaic panels can be easily installed at the same height in complex terrain with varying elevations. Compared to traditional methods, this significantly reduces labor input and construction costs, while greatly minimizing the ecological damage caused by constructing numerous cement bases. It solves the problem of existing methods that require cement bases to adjust the height of each photovoltaic support pillar in most complex terrains to achieve a uniform horizontal position after installation. This method necessitates leveling the land and pouring foundations point by point according to the terrain, resulting in high labor input, long construction periods, and high material costs. Excavating multiple cement bases can also easily damage vegetation, disturb the soil, and cause significant ecological damage.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
