[0002] A lightning protection device refers to the sum of lightning rods, down conductors, grounding devices, surge protectors (SPDs) and other connecting conductors. Generally, a building's lightning protection device is divided into two categories: external lightning protection devices and internal lightning protection devices. External lightning protection devices consist of lightning rods, down conductors and grounding devices, that is, traditional lightning protection devices. Internal lightning protection devices are mainly used to reduce lightning currents and their electromagnetic effects inside buildings, such as using electromagnetic shielding, equipotential bonding and installing surge protectors (SPDs) to prevent the hazards that may be caused by lightning electromagnetic pulses.

[0003] For example, publication number CN214313562U discloses "A lightning protection and grounding device for power engineering buildings", which includes a main body, a first connecting plate fixedly connected to the bottom of the main body, a first threaded hole provided on the first connecting plate, a first bolt threadedly connected to the first threaded hole, a telescopic plate fixedly connected to the bottom of the first connecting plate, a second connecting plate fixedly connected to the bottom of the telescopic plate, a groove provided on the main body, a slide groove provided on the side of the groove, a sliding rod fixedly connected to the inside of the slide groove, a spring provided on the outer surface of the sliding rod, a first slider slidably connected to the sliding rod, and through the action of the first threaded hole, the first bolt, the telescopic plate and the second connecting plate, when the device is installed on the power engineering building, its setting can make the connection between the entire device and the power engineering building relatively tight.

[0004] Although the above-mentioned lightning protection grounding device has certain advantages in installation and fixation, it still has certain disadvantages: when using the above-mentioned lightning protection grounding device for transportation, the length of the connecting pipe is relatively long, which is more troublesome to transport and cannot be transported conveniently. At the same time, a down conductor is provided in the connecting pipe. When the down conductor needs to be repaired, the entire connecting pipe needs to be removed for inspection. This method is more troublesome, takes a long time and effort, and is inconvenient to use. Utility Model Content
