Description

Technical Field

[0002] A lightning rod, also known as a lightning protection rod or a lightning conductor, is an important device used to protect buildings, tall trees, etc. from the harm of lightning strikes. A lightning rod is a device that installs a lightning conductor on the top of the protected object, uses the discharge or dissipation of electric charge at the tip to guide or eliminate lightning, and conducts the lightning current into the earth, thereby protecting the protected object from lightning strikes.

[0003] In real life, some lightning rods are not grounded as required and are invalid lightning rods. The purpose of lightning rod testing is to prevent this phenomenon from occurring. When testing lightning rods, lightning rods are usually located on the top floor of a building, and the detection equipment must be inserted into the ground. Long lines are usually used to connect clips to hold the lightning rods. Under long-term exposure to the open air, the surface of the lightning rod will usually rust. In order not to affect the test results, sandpaper is usually used to grind the lightning rod. Then, the lightning rod is clamped with a clip. However, it is very inconvenient to use sandpaper to grind some lightning rods in special locations, and the preliminary preparation time is long, which affects efficiency. Utility Model Content
