Description

Technical Field

[0001] This utility model belongs to the field of lightning protection technology, specifically relating to a lightning protection mechanism for photovoltaic power stations. Background Technology

[0002] Renewable energy sources such as solar, wind, hydro, and geothermal energy are developing rapidly and have become a new path for sustainable development. my country has abundant solar energy resources. However, since most solar photovoltaic power generation equipment is installed in open and remote outdoor environments, it is easily affected by lightning strikes, which can cause equipment damage or power outages, and even threaten personal safety. Therefore, it is very important to take relevant lightning protection measures for solar photovoltaic power generation systems. At present, most of the methods used for lightning protection are to install lightning rods. However, lightning rods are exposed to the outdoor environment for a long time and are subject to erosion by various natural factors, such as weathering and corrosion. These factors will reduce the performance and lifespan of the lightning rods, so regular inspection and replacement are necessary.

[0003] Traditional lightning rod installation methods are often quite simple. Under severe weather conditions such as thunderstorms and strong winds, lightning rods are easily broken or displaced due to the strong winds and lightning strikes, affecting their normal lightning protection function and thus threatening the safe and stable operation of the entire photovoltaic power station. Furthermore, traditional methods are not convenient or efficient for installing and dismantling lightning rods, making it difficult to replace damaged rods promptly. Therefore, a lightning protection mechanism for photovoltaic power stations is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a lightning protection mechanism for photovoltaic power plants that is easy to install and has strong stability in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A lightning protection mechanism for a photovoltaic power station includes a photovoltaic panel and a mounting base, wherein a lightning rod is installed on the mounting base, and a lightning protection flat iron is installed between the photovoltaic panel and the mounting base;

[0007] It also includes:

[0008] A mounting bracket, which is slidably mounted on a mounting base;

[0009] An opening and closing mechanism is provided in the mounting base. The fixing frame moves inward by pressing the opening and closing mechanism with a lightning rod.

[0010] As a further optimization of this utility model, the mounting base is provided with an embedded cylinder, the embedded cylinder is provided with a mounting plate, the inner surface of the mounting base is provided with positioning grooves on both sides, the mounting base is provided with sliding grooves, the sliding grooves are located on both sides of the embedded cylinder, the fixing bracket is slidably disposed in the sliding grooves, and the mounting base is provided with a ground wire.

[0011] As a further optimization of this utility model, the opening and closing mechanism includes a sliding rod, which is slidably mounted on the mounting plate. A pressure plate is provided at the upper end of the sliding rod, and a spring is provided between the pressure plate and the mounting plate. A rotating seat is provided at the lower end of the sliding rod. Push rods are slidably mounted on both sides of the embedded cylinder, and a connecting rod is hinged between the push rod and the rotating seat.

[0012] As a further optimization of this utility model, the push rod passes through the embedded cylinder and is fixedly connected to the fixing frame. The upper end of the fixing frame is provided with a clamping ring, which is a semi-circular structure.

[0014] As a further optimization of this utility model, a fixing bolt is provided between the embedded cylinder and the lightning rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] Unlike existing technologies, when installing a lightning rod, the downward movement of the lightning rod triggers an opening and closing mechanism, causing the fixing frame to move inward. The semi-circular clamping ring at the upper end clamps and fixes the lightning rod, effectively preventing it from breaking. This greatly improves the stability of the lightning rod in severe weather and ensures the reliable implementation of lightning protection. Moreover, the operation is simple and quick when disassembling and replacing the lightning rod. When the lightning rod is lifted to the initial position of the pressure plate, the clamping ring fully opens, and the lightning rod can be completely removed by simply lifting it to the height of the embedded cylinder.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 - Figure 4 As shown, a lightning protection mechanism for a photovoltaic power station includes a photovoltaic panel 1 and a mounting base 2. A lightning rod 3 is installed on the mounting base 2, and a lightning protection flat iron is installed between the photovoltaic panel 1 and the mounting base 2.

[0025] It also includes:

[0026] Fixture 4 is slidably mounted on mounting base 2;

[0027] The opening and closing mechanism 6 is installed in the mounting base 2. The lightning rod 3 presses against the opening and closing mechanism 6, causing the fixing frame 4 to move inward.

[0028] The mounting base 2 is provided with an embedded cylinder 22, and an installation plate 222 is provided inside the embedded cylinder 22. Positioning grooves 221 are opened on both sides of the inner surface of the mounting base 2. Sliding grooves 21 are opened on the mounting base 2 and are located on both sides of the embedded cylinder 22. The fixing frame 4 is slidably disposed in the sliding groove 21. The fixing frame 4 can move in a specified direction through the sliding groove 21, so that the fixing frame 4 can move accurately inward under the action of the opening and closing mechanism 6. A ground wire 23 is provided on the mounting base 2. Lightning is safely guided to the ground wire 23 on the mounting base 2 through the lightning protection flat iron, so as to realize the lightning protection of the photovoltaic power station.

[0029] The opening and closing mechanism 6 includes a sliding rod 61, which is slidably mounted on the mounting plate 222. A pressure plate 611 is provided at the upper end of the sliding rod 61, and a spring 65 is provided between the pressure plate 611 and the mounting plate 222. A rotating seat 62 is provided at the lower end of the sliding rod 61. Push rods 63 are slidably mounted on both sides of the embedded cylinder 22. A connecting rod 64 is hinged between the push rod 63 and the rotating seat 62. When the lightning rod 3 presses against the pressure plate 611, the sliding rod 61 moves down, and the push rod 63 moves through the connecting rod 64, thereby moving the fixing frame 4 inward to clamp and fix the lightning rod 3.

[0030] After the push rod 63 passes through the embedded cylinder 22, it is fixedly connected to the fixing frame 4. The upper end of the fixing frame 4 is provided with a clamping ring 41. The clamping ring 41 has a semi-circular structure, which facilitates the clamping and fixing of the lightning rod 3. In thunderstorms, when the lightning rod 3 is subjected to external force, the fixing frame 4 can enhance the stability of the lightning rod 3, prevent it from breaking, and ensure the lightning protection effect.

[0031] The lightning rod 3 has positioning blocks 31 on both sides. The positioning blocks 31 can be embedded in the positioning grooves 221, and the embedding cylinder 22 is sleeved on the lightning rod 3.

[0032] A fixing bolt 5 is provided between the embedded cylinder 22 and the lightning rod 3.

[0033] It should be noted that the working principle of the lightning protection mechanism for this photovoltaic power station is as follows: When installing the lightning rod 3, the positioning blocks 31 on both sides of the lightning rod 3 are embedded into the positioning grooves 221 on both sides of the embedded cylinder 22 on the mounting base 2, and the embedded cylinder 22 is sleeved on the lightning rod 3 and further fixed by the fixing bolts 5. As the lightning rod 3 moves down in the embedded cylinder 22, the pressure plate 611 is pressed down by force, which drives the sliding rod 61 to slide down along the mounting plate 222, compressing the spring 65. The rotating seat 62 at the lower end of the sliding rod 61 then descends, and the push rods 63 that are slidably installed on both sides of the embedded cylinder 22 move inward through the connecting rod 64. Since the push rods 63 are fixedly connected to the fixing frame 4 that is slidably installed in the sliding groove 21 on the mounting base 2 after passing through the embedded cylinder 22, the fixing frame 4 will move inward. The semi-circular clamping ring 41 at the upper end can clamp and fix the lightning rod 3. The fixing frame 4 supports the lightning rod 3, which can effectively prevent the lightning rod 3 from breaking and improve the stability of the lightning rod 3 in thunderstorms and strong winds. At the same time, when disassembling and replacing the lightning rod 3, it will be lifted. When the lightning rod 3 is lifted to the initial position of the pressure plate 611, the clamping ring 41 will be fully opened. Then, the lightning rod 3 can be completely removed by simply lifting it to the height of the embedded cylinder 22.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
