Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic installation technology, specifically relating to an installation structure for a photovoltaic power station on a coal gangue hill. Background Technology

[0002] Currently, the common method for installing photovoltaic (PV) systems on mountainsides is through reinforced concrete drilling and grouting. This involves drilling large areas of holes at the installation site, pouring concrete into the holes to form cast-in-place piles, and then erecting the PV systems on these piles. However, when installing PV systems on coal gangue mountains, the large-scale drilling can introduce instability and increase the risk of collapse and landslides, given that coal gangue mountains are naturally deposited coal gangue. Although wind farms have been used to manage this, there are still risks of collapse, landslides, and spontaneous combustion. Therefore, installing PV systems on coal gangue mountains presents significant risks due to the inherent instability of the area. Utility Model Content

[0003] This utility model provides a photovoltaic power station erection structure for coal gangue hills, which aims to solve the problem in the prior art that the erection of photovoltaic supports on coal gangue hills can easily affect the stability of the hill and cause danger.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a photovoltaic power station erection structure for a coal gangue hill, comprising:

[0005] The foundation support is cast on the slope of the coal gangue mountain, and the length direction of the foundation support is set along the slope inclination direction.

[0006] Multiple support columns are fixedly installed on the foundation support.

[0007] A photovoltaic frame is installed on multiple of the aforementioned support columns.

[0008] In one possible implementation, the foundation support includes a top platform at the mountaintop, a bottom platform at the foot of the mountain, and a sloping platform on the mountainside between the top platform and the bottom platform.

[0009] In one possible implementation, the foundation support is a monolithically cast structure.

[0010] In one possible implementation, the top and bottom of the coal gangue mountain are respectively provided with foundation pits for pouring the top platform and the bottom platform.

[0016] Fasteners, threadedly connected to the pre-embedded bolts, are used to fix the mounting plate to the column.

[0017] In one possible implementation, the pre-embedded bolt is also threaded with a support member, which is located on both sides of the mounting plate, along with the fastener.

[0018] In one possible implementation, the column includes a molded tube pre-embedded inside the foundation support, and a cast column poured inside the molded tube.

[0019] In one possible implementation, the inner wall of the mold tube is provided with a plurality of anti-slip grooves, which are spaced apart along the length of the mold tube.

[0020] In one possible implementation, the hillside inclined platform includes a plurality of spaced vertical ribs, the length direction of which is arranged along the slope direction, and a supporting rib is provided between two adjacent vertical ribs.

Detailed Implementation

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please refer to the following: Figures 1 to 3 The present invention describes the supporting structure for a photovoltaic power station on a coal gangue hill. The supporting structure includes a foundation support 1, support columns 2, and a photovoltaic frame 3. The foundation support 1 is cast into the slope of the coal gangue hill, and its length is aligned with the slope's inclination direction. Multiple support columns 2 are fixedly installed on the foundation support 1. The photovoltaic frame 3 is installed on the multiple support columns 2.

[0029] The photovoltaic power station erection structure provided in this embodiment, compared with the prior art, involves pouring a foundation support 1 on the slope of the coal gangue hill. Multiple support columns 2 are installed on top of the foundation support 1, arranged sequentially along the slope's inclination direction. Finally, the photovoltaic frame 3 is erected on these support columns 2. During construction, a casting mold can be erected on the coal gangue hill. The foundation support 1 and support columns 2 are first poured onto the slope, forming multiple support columns 2 without damaging the structure of the coal gangue hill. The photovoltaic frame 3 is then erected on these support columns 2, thus completing the photovoltaic support structure erection. This avoids drilling into the coal gangue hill slope, improving the stability of the coal gangue hill and consequently enhancing the stability of the photovoltaic power station erected on it.

[0030] Specifically, in this embodiment, a cable tray for accommodating cables is also erected on the base support 1, so that the cable tray can be run between multiple base supports 1, which facilitates the wiring operation of photovoltaic equipment in the later stage.

[0031] In some embodiments, the aforementioned basic support 1 may adopt the following approach: Figure 1 The structure shown. See also Figure 1The foundation support 1 includes a top platform 11 located at the mountaintop, a bottom platform 12 located at the foot of the mountain, and a sloping platform 13 located between the top platform 11 and the bottom platform 12. Planes for casting the top platform 11 and the bottom platform 12 are pre-machined at the top of the coal gangue hill, ensuring that both the top and bottom of the foundation support 1 can support forces along the vertical direction. This prevents the foundation support 1 from sliding down the slope under the weight of the photovoltaic power station and enhances its supporting effect, thereby improving the stability of the photovoltaic power station support.

[0032] In some embodiments, the aforementioned basic support 1 may adopt the following approach: Figure 1 The structure shown. See also Figure 1 The foundation support 1 adopts an integral cast-in-place structure. During the casting process, the support mold can be erected on the coal gangue hill, and a steel reinforcement support frame can be installed inside the support mold. Molds for casting the top platform 11 and bottom platform 12 are erected at the top and bottom of the slope, and the top platform 11, bottom platform 12 and the hillside inclined platform 13 are interconnected, achieving integral casting during the casting process. This facilitates on-site construction and casting, while also enhancing the overall strength of the foundation support 1.

[0033] In some embodiments, the aforementioned basic support 1 may adopt the following approach: Figure 1 The structure shown. See also Figure 1 The top and bottom of the coal gangue mountain are respectively provided with foundation pits for pouring the top platform 11 and the bottom platform 12. When pouring the foundation support 1, it is preferable to pre-excavate foundation pits at the top and bottom of the coal gangue mountain so that the poured top platform 11 and bottom platform 12 are located inside the foundation pits. This can reduce the displacement of the foundation support 1 after pouring and improve the stability of the position of the foundation support 1.

[0034] Optionally, in this embodiment, the top platform 11 and the bottom platform 12 can be supported on one side of the curb at the top of the coal gangue mountain, increasing the support force on the foundation support 1 and ensuring stable support for the photovoltaic power station in the future.

[0035] In some embodiments, the aforementioned basic support 1 may adopt the following approach: Figure 1 The structure shown. See also Figure 1 The base support 1 has multiple staggered steps 14 arranged sequentially along the slope direction at its bottom. Before pouring the base support 1, multiple steps are pre-processed within the pouring area on the slope. After pouring, multiple staggered steps 14 are formed at the bottom of the base support 1. The arrangement of multiple staggered steps 14 can prevent the base support 1 from sliding down the slope, thereby improving the stability of the base support 1 on the slope.

[0036] In some embodiments, the aforementioned support column 2 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The support column 2 includes a column body 21, pre-embedded bolts 22, connecting rods 23, and fasteners 24. The column body 21 is fixedly installed on the foundation support 1 and protrudes from the foundation support 1. Multiple pre-embedded bolts 22 protrude from the top of the column body 21. A mounting plate 231 is fixedly installed at the bottom of the connecting rod 23, and the mounting plate 231 has mounting holes for installing the pre-embedded bolts 22. The photovoltaic frame 3 is installed on the connecting rod 23. The fasteners 24 are threadedly connected to the pre-embedded bolts 22 to fix the mounting plate 231 to the column body 21. The length of the support column 2 is vertical and protrudes from the top surface of the foundation support 1, thus avoiding interference between the photovoltaic power station and the foundation support 1 during installation. The column body 21 is pre-embedded during the pouring of the foundation support 1. Multiple pre-embedded bolts 22 are pre-embedded inside the column body 21, and the multiple pre-embedded bolts 22 are arranged in a ring with uniform intervals. When the connecting rod 23 is installed on the column 21, the connecting rod 23 is set in the vertical direction. The connecting rod 23 is fixedly installed in the middle of the mounting plate 231. When installing the connecting rod 23, the mounting plate 231 can be installed between multiple pre-embedded bolts 22, and the mounting plate 231 is fixed to the column 21 by fasteners 24. The structure is simple and the operation is convenient.

[0037] Specifically, in this embodiment, a connector is hinged at the top of the connecting rod 23. The connector is fixedly installed on the photovoltaic frame 3 by bolts, and the connection between the photovoltaic frame 3 and the connecting rod 23 can be realized through the connector.

[0038] In some embodiments, the connecting rod 23 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The pre-embedded bolts 22 are also threaded with support members 25, which are located on both sides of the mounting plate 231, along with the fasteners 24. Both the support members 25 and the fasteners 24 are nuts. When the mounting plate 231 is installed onto multiple pre-embedded bolts 22, the fasteners 24 are positioned above the mounting plate 231, and the support members 25 are positioned below it. Thus, the mounting plate 231 can be fixed to the pre-embedded bolts 22 using the fasteners 24 and the support members 25. Simultaneously, the height of the mounting plate 231 can be adjusted by adjusting the height of the support members 25, allowing for free adjustment of the height of the connecting rods 23 during the later installation of the photovoltaic frame 3, facilitating the connection between the photovoltaic frame 3 and the connecting rods 23.

[0039] In some embodiments, the column 21 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The column 21 includes a mold tube 211 pre-embedded inside the foundation support 1, and a cast column 212 cast inside the mold tube 211. During on-site construction, when casting the foundation support 1, the mold tube 211 can be placed inside the casting mold of the foundation support 1 in advance. After the foundation support 1 is cast, the pre-embedded bolts 22 are placed inside the mold tube 211, and then the cast column 212 is cast, which facilitates the overall forming of the column 21 and its connection with the foundation support 1.

[0040] In some embodiments, the above-mentioned mold tube 211 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The inner wall of the mold tube 211 is provided with multiple anti-slip grooves, which are spaced apart along the length of the mold tube 211. During the pouring of the column 212, the concrete can be poured into the anti-slip grooves, thereby preventing the column 212 from sliding inside the mold tube 211 and affecting the stability of the photovoltaic frame 3 installation.

[0041] Specifically, in this embodiment, the anti-slip groove is a ring-shaped structure or a spiral structure.

[0042] Preferably, in this embodiment, a plurality of annular protrusions are provided on the outer side of the mold tube 211, and the plurality of annular protrusions are arranged sequentially at intervals along the length direction of the mold tube 211. After the mold tube 211 is embedded in the foundation support 1, the stability of the mold tube 211 inside the foundation support 1 can be guaranteed.

[0043] In some embodiments, the aforementioned hillside inclined platform 13 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The hillside sloping platform 13 includes multiple spaced vertical reinforcement bars 131, arranged along the slope direction. Supporting reinforcement bars 132 connect adjacent vertical reinforcement bars 131. The two ends of each vertical reinforcement bar 131 are a top platform 11 and a bottom platform 12, respectively, with multiple vertical reinforcement bars 131 connected to the same top platform 11 or bottom platform 12. The vertical reinforcement bars 131 are used to install the support columns 2, and the supporting reinforcement bars 132 are used to strengthen the support between adjacent vertical reinforcement bars 131, thereby effectively improving the overall strength of the foundation support 1. Simultaneously, the arrangement of vertical reinforcement bars 131 and supporting reinforcement bars 132 reduces the pouring area on the slope, decreasing on-site construction materials and thus reducing construction costs.

[0044] The above description is only a preferred embodiment of the present utility model and is 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.
