Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic lightning protection technology, specifically relating to a photovoltaic array lightning protection structure. Background Technology

[0002] A photovoltaic (PV) array, often simply called a solar cell array, refers to a power generation unit formed by connecting and installing multiple photovoltaic modules together electrically and mechanically. Because PV arrays are typically installed in open, prominent locations, they are highly susceptible to lightning strikes. Therefore, their lightning protection structure is crucial for the safe and reliable operation of the system. Its main purpose is to prevent direct lightning strikes from damaging equipment and to suppress lightning-induced overvoltages from damaging electrical components. Lightning rods are a very common component of lightning protection structures.

[0003] Existing lightning rods are usually installed at high altitudes by welding or bolting. However, welding requires hot work and cutting at high altitudes, which poses a high risk. Although bolts are removable, they are difficult to loosen after years of corrosion. This makes it difficult for workers to disassemble and maintain the lightning rods after climbing to high altitudes, thus affecting the stability of the photovoltaic array lightning protection structure. Utility Model Content

[0004] To address the aforementioned technical issues, this invention designs a photovoltaic array lightning protection structure, which facilitates the quick disassembly of the lightning rods for regular maintenance, thereby reducing safety risks and improving work efficiency.

[0005] The photovoltaic array lightning protection structure of this utility model includes a concrete tower and a lightning rod. A support column is installed on the top of the concrete tower, and a column is welded to the top of the support column. A ring is welded on the column, and a turntable is sleeved on the ring. A fixing component is welded to the top of the turntable, and the fixing component is snapped into the limiting seat at the bottom of the lightning rod. A limiting plate is inserted into the turntable, and a lifting plate is welded to the bottom of the limiting plate.

[0006] The column has an I-shaped cross section, and the top circumference of the column has through holes at equal intervals for the limiting seat to pass through. The bottom of the limiting seat is provided with a transverse U-shaped groove, and an L-shaped fastener is engaged in the U-shaped groove.

[0007] Multiple guide rods are slidably connected to the inner wall of the lifting plate. The bottom of the guide rods is welded to the support plate, and the support plate is welded and fixed to the column. A spring is also connected between the support plate and the lifting plate.

[0008] Both the turntable and the outer wall of the lifting plate are welded with handles.

[0009] A base is fixedly connected to the outer side of the top of the concrete tower. Separate semi-circular fixed cylinders are connected to the top two sides of the base. A rotating cylinder is inserted inside the fixed cylinder. A protective cover is connected to the top of the rotating cylinder. Both the protective cover and the outer wall of the rotating cylinder are connected to extension plates.

[0010] The concrete tower has ladders on both sides of its outer wall.

[0011] The beneficial effects of this utility model are:

[0012] Compared with existing technologies, the photovoltaic array lightning protection structure of this utility model removes the connection between the fixing component and the limiting seat by rotating the turntable, thereby eliminating the limitation on the lightning rod. It eliminates the need to violently rotate the rusted bolts, avoiding the risk of flying metal fragments or broken tools falling from the sky and injuring people. The lightning rod can be quickly disassembled for regular maintenance, thereby reducing safety risks and improving work efficiency. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] See Figures 1 to 9 As shown, the photovoltaic array lightning protection structure proposed in this embodiment includes a concrete tower 1 and a lightning rod 4. A support column 2 is installed on the top of the concrete tower 1, and a column 3 is welded to the top of the support column 2. A ring 9 is welded to the column 3, and a turntable 8 is fitted onto the ring 9, allowing the turntable 8 to rotate around the ring 9. A fixing member 7 is welded to the top of the turntable 8, and the fixing member 7 is engaged with a limiting seat 6 at the bottom of the lightning rod 4. Specifically, as... Figures 3 to 6 As shown, the column 3 has an I-shaped cross section. Three through holes 301 are equidistantly opened on the top circumference of the column 3 for the limit seat 6 to pass through. The bottom of the limit seat 6 is provided with a transverse U-shaped groove, and the L-shaped fastener 7 is engaged in the U-shaped groove.

[0028] See Figure 7 and Figure 8 A limit plate 10 is inserted inside the turntable 8. A lifting plate 11 is welded to the bottom of the limit plate 10. Four circumferentially distributed guide rods 12 are slidably connected to the inner wall of the lifting plate 11. The bottom of the guide rods 12 is welded to the support plate 13. The support plate 13 is welded and fixed to the column 3. A spring 14 is also connected between the support plate 13 and the lifting plate 11.

[0029] See Figure 1 and Figure 2 After the concrete tower 1 is erected at the photovoltaic array installation location, the support column 2, column 3 and lightning rod 4 are transported to the vicinity of the concrete tower 1. The separate design of the support column 2, column 3 and lightning rod 4 reduces the transportation pressure. Then, the support column 2, column 3 and lightning rod 4 are erected and fixed vertically from bottom to top. In the event of thunderstorms, the lightning rod 4 at the top will attract lightning, so that the lightning is conducted to the ground through the grounding wire connected to the lightning rod 4, thereby protecting the photovoltaic array.

[0030] See Figures 3-8When using this device, pull the lifting plate 11 down along the guide rod 12 to compress the spring 14 until the limiting plate 10 is disengaged from the turntable 8; then push the turntable 8 to rotate along the ring 9 until the fixing part 7 is disengaged from the limiting seat 6, thus canceling the limiting of the lightning rod 4. The lightning rod 4 can then be disassembled for replacement or maintenance, thus eliminating the need for violently turning rusted bolts, which could cause flying metal fragments or broken tools to fall from a height and injure people, or for high-risk cutting operations at heights. The lightning rod 4 can be quickly disassembled for regular maintenance, thereby reducing safety risks and improving work efficiency.

[0031] When installing the lightning rod 4, insert the limiting seat 6 into the top of the column 3, rotate the turntable 8 to engage the top of the fixing part 7 with the limiting seat 6, then the spring 14 returns to its original position, the lifting plate 11 moves up, and the limiting plate 10 is inserted into the turntable 8, thus completing the installation of the lightning rod 4.

[0032] To facilitate the rotation of the turntable 8 and the pressing of the lifting plate 11, handles 801 are welded to the outer walls of both the turntable 8 and the lifting plate 11.

[0033] To facilitate the installation and maintenance of lightning rod 4, ladders 5 are also installed on both sides of the outer wall of the concrete tower 1.

[0034] See Figure 1 , Figure 2 and Figure 9 As shown, a base 15 is fixedly connected to the outer side of the top of the concrete tower. Separate semi-circular fixed cylinders 16 are connected to the top two sides of the base 15. A rotating cylinder 17 is inserted inside the fixed cylinder 16. A protective cover 18 is connected to the top of the rotating cylinder 17, and extension plates 19 are connected to both the protective cover 18 and the outer wall of the rotating cylinder 17.

[0035] When installing the protective cover 18, install the base 15, the fixed cylinder 16, the rotating cylinder 17, and the protective cover 18 in sequence, and then combine them in pairs to form a circular enclosure to improve the protective performance of the bottom of the lightning rod 4, prevent bird strikes, and thus protect the support components at the bottom of the lightning rod 4, thereby improving the support stability and durability of the lightning rod 4.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
