Description

Technical Field

[0001] This utility model relates to the field of lightning rod technology, specifically to an insulated and rainproof internal lightning rod. Background Technology

[0002] A lightning rod, also known as a lightning arrestor or lightning rod, is a device used to protect buildings, tall trees, and other structures from lightning strikes. A lightning arrester is installed at the top of the protected object and connected to an underground grounding network using a compliant conductor.

[0003] However, ordinary lightning rods lack insulation, making them prone to allowing lightning to be conducted into buildings and causing danger; the insulation lacks rainproof features, and rainwater wets the insulator, causing it to lose its insulating properties; the grounding wire of ordinary lightning rods is hung on the outside, which is prone to aging and is unsightly, and can easily cause accidents when blown back and forth by the wind. Therefore, we propose an insulated and rainproof internal lightning rod. Utility Model Content

[0006] Preferably, the outer thread of the external threaded connector is connected to an internal threaded connector, and a second column is fixedly connected inside the internal threaded connector, with a lightning arrester fixedly connected to the top of the second column.

[0007] Preferably, a grounding wire is fixedly connected to the bottom of the terminal block, and one end of the grounding wire passes through the first column and the hollow insulating column and extends to the outside of the first column and is fixedly connected to a grounding device.

[0008] Preferably, the first column, the second column, and the lightning arrester are all made of metal.

[0009] Preferably, one of the insulating rainproof umbrellas has a connecting sleeve inside, and the first upright and the hollow insulating column are connected by the connecting sleeve.

[0010] Preferably, the wiring terminal and the terminal connector are fixed by bolts.

[0011] Preferably, the terminal block is made of copper.

[0012] This utility model provides an insulated and rainproof internal lightning rod, which has the following beneficial effects: 1. This insulated and rainproof internal lightning rod is easier to install and maintain by routing the grounding wire inside the first column and the hollow insulated column. The routing of the grounding wire inside the first column and the hollow insulated column also makes the grounding wire less prone to aging, thus increasing its service life. The cooperation between the hollow insulated column and the insulated rainproof umbrella improves the insulation performance, prevents lightning from entering the building, and enhances the practicality of this insulated and rainproof internal lightning rod.
