Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support foundations, specifically to a photovoltaic support for use in mountainous steep slope rocky geological areas. Background Technology

[0002] Implementing photovoltaic projects in mountainous areas presents a variety of challenges. First, the complex and varied terrain with steep slopes not only increases construction difficulty but can also lead to unstable equipment operation, impacting efficiency. Second, frequent gully formations challenge site stability, increasing the risk of geological disasters and posing safety hazards to foundation construction. Third, widespread rock formations and protruding rock formations increase construction difficulty and costs. Furthermore, the unique geological conditions of mountains, including underground caves and faults, further increase construction risks and uncertainties. Simultaneously, the fragile ecosystem of mountains necessitates careful environmental protection during construction to avoid ecological damage. These intertwined issues present significant challenges to the construction of mountainous photovoltaic power stations, requiring designers and construction teams to fully consider various factors and develop reasonable solutions to ensure successful project implementation.

[0003] Photovoltaic support foundations are a crucial component of photovoltaic power generation projects. These foundations come in various forms and are numerous. Selecting safe, economical, and suitable foundations for complex and varied mountainous terrain, while maximizing land utilization, has become a key focus and challenge in the civil engineering design of mountain photovoltaic power stations. During the implementation of mountain photovoltaic projects, problems frequently arise at some sites, such as those described above, including steep slopes, well-developed gullies, abundant rocks, or exposed rock formations. In some areas, the slope can exceed 45 degrees, making it extremely difficult for construction equipment to climb and operate. Due to the steep slopes, large cranes face significant difficulties in transporting and installing photovoltaic panels. The development of gullies also poses considerable challenges to construction; some gullies can reach depths of over 5 meters and widths of over 10 meters, preventing conventional drilling equipment from accessing the site for foundation construction and making the land unusable.

This support system consists of anchor rods, connecting sleeves, transition steel bars, foundation ends, and mortar. It fully utilizes the mechanical properties of rock and features small hole diameter and shallow hole depth, allowing for drilling using handheld rock drilling equipment. This effectively solves the problem of large machinery being unable to enter the site for construction and increases the available land for the project.

[0011] Furthermore, a layer of cement mortar is filled between the first support and the drilled hole.

[0012] Furthermore, the first support component includes an anchor bolt.

[0013] Furthermore, the second support includes multiple transition steel bars, one end of which is evenly arranged around the end of the first support, and the other end of which forms a groove for receiving the end of the connecting sleeve. One end of the connecting sleeve is embedded in the groove along the coaxial direction of the first support frame.

[0014] Furthermore, the connection ends of multiple transition steel bars and the first support member extend into the cement mortar layer.

[0015] Furthermore, the transition steel bars are connected to the connecting sleeve and the first support member by double-sided welds.

[0016] Furthermore, the diameter of the connecting sleeve is larger than the diameter of the first support member.

[0017] Furthermore, the connection between the connecting sleeve and the second support is also wrapped with a foundation end, which connects to the surface of the steep slope rock.

[0027] Example 1

[0028] A photovoltaic support system for steep mountain slopes and rocky geological areas, such as Figure 3 As shown, the structure includes an anchor bolt 1, which extends into a borehole drilled into the steep rock slope 4. The borehole diameter is larger than that of the anchor bolt 1. The anchor bolt 1 is arranged along the central axis of the borehole. The gap between the borehole and the anchor bolt 1 is filled with a cement mortar layer 6, which is at the same height as the borehole opening. This direct support part is drilled using a handheld rock drilling device, which effectively solves the problem that large machinery cannot enter the site for construction and increases the available land for the project.

[0029] like Figure 2 As shown, it also includes three transition steel bars 5. One end of each of the three transition steel bars 5 is evenly arranged around one end of the anchor rod 1. The two adjacent bars of the three transition steel bars 5 are at 120°. The ends of the three transition steel bars 5 away from the anchor rod 1 form a circumferential distribution, and the diameter of the circumference is larger than the diameter of the anchor rod 1. The specific structure is funnel-shaped. The connecting sleeve 3 is clamped at the ends of the three transition steel bars 5 away from the anchor rod 1. That is, the connecting sleeve 3 is mounted at the top end of the transition steel bar 5. The part of the transition steel bar 5 near the end is in close contact with the body of the connecting sleeve 3. One end of the transition steel bar 5 connected to the anchor rod 1 extends into the cement mortar layer 6, and the two ends of the transition steel bar 5 are welded to the anchor rod 1 and the connecting sleeve 3 respectively by double-sided welding.

[0030] It also includes a foundation end 2, which is wrapped around the connection between the connecting sleeve 3 and the transition steel bar 5. The foundation end 2 is located on the surface of the steep rock 4 and is used to fix the connection between the connecting sleeve 3 and the transition steel bar 5, thus playing a reinforcing role.

[0031] The foundation type of this support consists of anchor rod 1, connecting sleeve 3, transition steel bar 5, foundation end 2, and cement mortar layer 6. It makes full use of the mechanical properties of rock, and the foundation has the characteristics of small hole diameter and shallow hole depth. It can be drilled using handheld rock drilling equipment, which effectively solves the problem of large machinery not being able to enter the site for construction, increases the available land for the project, and at the same time ensures the safety, economy and progress of the project. It provides a new idea for the selection of complex and ever-changing mountain photovoltaic support foundations.

Compared with the distribution of Embodiment 1, the distribution of this embodiment can provide more stable support for the connecting sleeve 3, forming support points in four directions, so that the connecting sleeve 3 has good stability when supporting the photovoltaic panel.

[0035] Example 3 is a further improvement on Example 1; further explanation: identical components will not be repeated here, such as... Figure 1 As shown, the connecting sleeve 3 and the anchor rod 1 are coaxially arranged in the vertical direction, resulting in a more concentrated force.

[0036] This utility model mainly consists of anchor rod 1, connecting sleeve 3, transition steel bar 5, foundation end 2, and mortar. It makes full use of the mechanical properties of rock, and the foundation has the characteristics of small hole diameter and shallow hole depth.
