Description

Technical Field

[0001] The present invention relates to the technical field of lightning protection equipment, and in particular to a self-powered intelligent lightning receptor. Background Art

[0002] Lightning rods are an important component of lightning protection devices and are usually installed at the top or high up in a building. They are used to directly receive lightning strikes and direct the lightning current into the grounding device. They utilize the tip discharge effect to actively attract the lightning current when lightning occurs, making themselves a discharge channel, thereby protecting the buildings or equipment below from damage caused by lightning strikes. For example, the Chinese invention patent disclosed in the existing announcement number CN217692097U discloses a lightning rod capable of early discharge, comprising a main lightning rod, a structural connecting rod provided at the bottom end of the main lightning rod, and a pre-discharge function triggering device provided on the outside of the structural connecting rod, a top cover provided at the top end of the pre-discharge function triggering device, and a plurality of groups of discharge side needles provided at the top end of the top cover; Some lightning rods need to use equalizing rings to equalize the spatial electric field, prevent backlash and assist in generating upward leaders. Most of the existing equalizing rings are fixed ring structures, which have the problems of limited electric field equalization range and insufficient lightning current conduction efficiency. In addition, traditional equalizing rings need to be welded and fixed as a whole or fixed with multiple rods and fasteners and bolts during assembly.
