Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a photovoltaic support suitable for mountainous areas. Background Technology

[0002] Against the backdrop of a global energy structure accelerating its transition towards cleaner and lower-carbon energy, mountain-based photovoltaic (PV) power is becoming an inevitable trend in the development of the PV industry due to its unique resource advantages and comprehensive benefits. Traditional PV power plants typically rely on flat land, but with increasingly scarce high-quality land resources, underdeveloped areas such as mountains and hills are becoming ideal choices. Mountain-based PV can fully utilize sloping terrain and, through scientific design, improve power generation efficiency per unit area, achieving efficient and intensive use of land resources.

[0003] Compared to conventional flatland photovoltaic installations, mountainous terrain presents significant challenges for photovoltaic (PV) support system installation. Single-column systems are commonly used in mountainous PV systems to adapt to these conditions. However, with the increasing frequency of extreme weather events such as strong winds and heavy snow, single-column systems suffer from poor wind resistance, leading to widespread collapses and severe economic losses. To avoid these issues, double-column systems with wind resistance are now widely used. However, in double-column systems, the angles of the PV modules at the top of the front and rear columns are fixed, and the weight borne by the front and rear columns supporting the PV modules is almost identical. Directly adjusting the column height to adapt to the terrain would destabilize the overall structure's center of gravity, significantly impacting its safety. Yet, mountainous terrain necessitates adjusting the column height; otherwise, the slope or uneven terrain could make installation extremely difficult. Utility Model Content

[0004] This utility model provides a photovoltaic support system suitable for mountainous areas. Its purpose is to ensure the stability of the center of gravity of the double-column support system while adjusting the installation height of the rear column of the support system to adapt to the mountainous terrain.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A photovoltaic support structure suitable for mountainous areas includes an inclined beam, a front support column located at the bottom of the inclined end of the inclined beam, and a rear support column located at the bottom of the inclined end of the inclined beam. A height adjustment component is provided between the rear support column and the inclined beam, which includes a sleeve fitted on the rear support column and an upper column located on the top of the sleeve. Multiple height adjustment holes are evenly opened on the side of the upper column along the length direction, and one of the height adjustment holes is connected to the inclined beam through a triangular piece.

[0007] Furthermore, multiple stiffening ribs are provided at intervals between the side of the upper column and the top of the sleeve.

[0008] Furthermore, multiple upper bolt holes are spaced apart on the upper side of the sleeve along its circumferential direction, and each upper bolt hole is provided with an upper tightening bolt; multiple lower bolt holes are spaced apart on the lower side of the sleeve along its circumferential direction, and each lower bolt hole is provided with a lower tightening bolt.

[0009] Furthermore, a through bolt hole is provided in the middle of the side of the sleeve, and a through bolt is installed in the through bolt hole.

[0010] Furthermore, a front diagonal brace is provided between the front support column and the diagonal beam, and a rear diagonal brace is provided between the rear support column and the diagonal beam.

[0011] This utility model has the following beneficial effects:

[0012] This invention utilizes a height adjustment assembly consisting of a sleeve, upper column, height adjustment hole, and triangular fitting to achieve flexible height adjustment of the photovoltaic support structure in complex mountainous terrain. This effectively adapts to different slopes and elevation differences, ensuring the flatness of the installation surface. The support structure, through multi-stage locking with upper and lower tightening bolts and through bolts, along with reinforcing ribs, ensures the stability and load-bearing capacity of the connection nodes. It boasts advantages such as wind and earthquake resistance, convenient installation, high adjustment precision, and simple maintenance, significantly improving the construction efficiency and long-term operational reliability of mountainous photovoltaic power stations.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] Please refer to Figure 1-2This embodiment describes in detail a photovoltaic support system suitable for mountainous areas, including an inclined beam 3, a front support column 1 located at the bottom of the inclined end of the inclined beam 3, and a rear support column 2 located at the bottom of the inclined end of the inclined beam 3. A height adjustment assembly 4 is provided between the rear support column 2 and the inclined beam 3, which includes a sleeve 41 sleeved on the rear support column 2 and an upper column 42 located on the top of the sleeve 41. Multiple height adjustment holes 43 are evenly opened on the side of the upper column 42 along the length direction, and one of the height adjustment holes 43 is connected to the inclined beam 3 through a triangular piece 44.

[0018] The inclined beam 3, as the main load-bearing component for photovoltaic panel installation, can be constructed using rectangular or C-shaped steel profiles. The front support column 1 is fixedly installed at a lower position on the hillside, with a foundation anchoring device at its base. The rear support column 2 is positioned at a higher position on the hillside, also with a foundation anchoring device at its base. The sleeve 41 is a tubular structure, its inner diameter matching the outer diameter of the rear support column 2, forming a clearance fit. Multiple height adjustment holes 43 are evenly spaced along the length of the side of the upper column 42. One of the height adjustment holes 43 is adjustablely connected to the inclined beam 3 via a triangular fitting 44. By selecting different height adjustment holes 43 to engage with the triangular fitting 44 and securing them with bolts, precise adjustment of the inclined beam 3's installation height can be achieved.

[0019] Furthermore, multiple stiffening ribs 45 are circumferentially spaced in the connection area between the side of the upper column 42 and the top of the sleeve 41. These stiffening ribs 45 are evenly distributed circumferentially to enhance the structural strength and stability of the connection between the upper column 42 and the sleeve 41. The stiffening ribs 45 are triangular or trapezoidal in shape, and their connection with the upper column 42 and the sleeve 41 is fixed by welding.

[0020] Furthermore, multiple upper bolt holes 411 are spaced apart along the circumferential direction on the upper side of the sleeve 41, each upper bolt hole 411 containing an upper tightening bolt 46; multiple lower bolt holes 412 are spaced apart along the circumferential direction on the lower side of the sleeve 41, each lower bolt hole 412 containing a lower tightening bolt 47. To increase the connection stability between the sleeve 41 and the rear support column 2, multiple upper bolt holes 411 and upper tightening bolts 46 are provided circumferentially on the upper side of the sleeve 41. These upper bolt holes 411 and upper tightening bolts 46 are evenly distributed along the circumference of the sleeve 41, used to press and fix the rear support column 2 from above. A protective pad can be provided at the end of the upper tightening bolt 46 to prevent damage to the surface of the rear support column 2. The lower tightening bolts 47 and the upper tightening bolts 46 are kept at a certain distance in the vertical direction, forming two sets of fastening points. The lower tightening bolt 47 has the same structure as the upper tightening bolt 46, and its end can also be provided with a corresponding protective pad.

[0021] Furthermore, a through bolt hole 413 is provided in the middle of the side of the sleeve 41, and a through bolt 48 is installed in the through bolt hole 413. The through bolt 48 passes through the through bolt hole 413 and penetrates both side walls of the sleeve 41, and is fastened with a nut. The through bolt 48 ensures a firm connection between the sleeve 41 and the rear support column 2.

[0022] Furthermore, a front diagonal brace 5 is provided between the front support column 1 and the inclined beam 3, and a rear diagonal brace 6 is provided between the rear support column 2 and the inclined beam 3. In order to increase the connection stability between the front support column 1 and the inclined beam 3, and between the rear support column 2 and the inclined beam 3, and to prevent the support from failing in windy and snowy weather, a front diagonal brace 5 is provided between the front support column 1 and the inclined beam 3, and a rear diagonal brace 6 is provided between the rear support column 2 and the inclined beam 3. The front support column 1, the inclined beam 3, and the front diagonal brace 5 together form a main triangular stable structure, and the rear support column 2, the inclined beam 3, and the rear diagonal brace 6 form another triangular stable structure. The combination of the two stable triangular structures can effectively resist the wind load, snow load, and other external loads transmitted from the photovoltaic modules.

[0023] In the actual installation process, the installation positions of the front support column 1 and the rear support column 2 are first determined based on the characteristics of the mountainous terrain. After the foundation construction is completed, the front support column 1 is installed in place and its verticality is adjusted. Then, the rear support column 2 is installed, with the sleeve 41 fitted onto it. The appropriate height adjustment hole 43 position is selected according to the design elevation, and the inclined beam 3 is connected via the triangular fitting 44. After the inclined beam 3 is installed, the upper tightening bolt 46, the lower tightening bolt 47, and the through bolt 48 are tightened sequentially to ensure the stability of the entire support system.

[0024] This embodiment details the specific structural composition of the mountain photovoltaic support system and the connection relationships of its components. The height adjustment component 4 effectively solves the technical problems of large elevation differences and difficult construction in mountainous terrain. The entire system adopts a modular design, facilitating transportation and on-site installation. This support system features convenient adjustment, quick installation, and strong adaptability, and can meet the special requirements of photovoltaic support system installation in various complex mountainous terrains.
