[0002] A building refers to an engineering entity that is constructed through the construction of various types of housing buildings and their ancillary facilities. Buildings are often prone to lightning strikes due to their high height. Once struck by lightning, the buildings will be destroyed, so it is necessary to install lightning protection devices above the buildings.

[0003] At present, buildings are usually equipped with lightning rods for grounding and lightning protection. However, the current lightning rods are difficult to raise and lower according to the main height of the building, which will make the process of adjusting the lightning protection height range of the lightning rods complicated and reduce the installation speed of the lightning rods. For this reason, we propose a building lightning protection device to solve the above problems. Utility Model Content
