Claim Text:
1. A bipolar lightning rod apparatus, comprising: a fixation plate; a rod member configured to have a first end connected to the fixation plate in a length direction of the rod member and charged with electric charges of a ground; at least two insulators installed in the length direction of the rod member; an electrification plate installed between adjacent insulators, electrically insulated from the rod member, and charged with electric charges having an opposite polarity to the electric charges of the ground; an electrification tube installed between the electrification plate and the insulators, electrically connected to the electrification plate, and charged with electric charges having an opposite polarity to the electric charges of the ground; and a rod cap connected to a top of the rod member and configured to induce a falling of a thunderbolt; and binding means for stable binding between the fixation plate and the rod member, wherein the rod cap is configured to have an outside diameter relatively greater than an outer diameter of the insulators so that discharge efficiency is increased by greatly increasing an area into which the falling of a thunderbolt is induced, and wherein the rod cap comprises: a first cap of a dome shape; a second cap coupled to an outer circumference of the first cap in a radius direction of the first cap; and a coupling member configured to couple the first cap to the rod member, wherein the coupling member comprises a base plate configured to have a coupling hole formed therein and a first coupling tool coupled to the coupling hole of the base plate, wherein a multi-staged fitting jaw is formed in an outer circumference direction and in a length direction of the first coupling tool, wherein a coupling plate is located between the first cap and the base plate and has fitting pieces at one end thereof, wherein the fitting pieces of the coupling plate are coupled with the multi-staged fitting jaw of the first coupling tool through a press type coupling structure and the other end of the coupling plate is fixed on the first cap wherein the fixation plate and the rod member are coupled by a second coupling tool protruded from the fixation plate, and wherein the binding means comprises a wire configured to have a first end inserted into a support that is disposed on one side of the rod member in the length direction of the rod member and spirally wound in the length direction of the rod member, a fastening bolt configured to have a through groove through which a second end of the wire penetrates formed at the side of a head of the fastening bolt and inserted into a side of the second coupling tool, and a stopper member installed at the second end of the wire and configured to prevent the wire from being separated from the fastening bolt.
