Description

A multi-angle lightning rod

technical field

The utility model belongs to the technical field of lightning protection facilities, in particular to a multi-angle lightning protection rod.

Background technique

Lightning rod, also known as lightning rod, lightning rod, lightning arrester, lightning terminal, is a device used to protect buildings, tall trees, etc. from lightning strikes. When the thundercloud discharge is close to the ground, the ground electric field will be distorted. At the top of the lightning rod, a space where the local electric field is concentrated is formed to affect the development direction of the lightning pilot discharge, guide the lightning to discharge to the lightning rod, and then introduce the lightning current into the ground through the grounding down-conductor and the grounding device, so that the protected object is protected from lightning strikes .

However, the current lightning rod is only a single lightning rod, and the lightning effect is not obvious. In order to more effectively attract lightning to strike the lightning rod, the existing technology makes the lightning rod generate ions, thereby making it easier for lightning to discharge to the lightning rod. The effect of attracting lightning.

Lightning shielding and side strike lightning.

In order to achieve the above-mentioned purpose, the technical scheme adopted by the present utility model is: it comprises a circular base, a main connecting column, a secondary connecting column, a cross-reinforced connecting rod, a docking fixed seat, a main lightning rod, an externally inclined lightning rod, and a grounding wire connecting groove; A main connecting column is arranged in the middle of the upper end of the circular base, and a circle of auxiliary connecting columns is arranged on the outer side of the main connecting column, and the main connecting column and the auxiliary connecting column are reinforced and connected by cross reinforcement connecting rods, and each auxiliary connecting column is reinforced and connected. The columns are also reinforced and connected by cross reinforcement connecting rods; the top of the main connecting column is connected with the main lightning rod through the docking fixed seat, and the upper end of the auxiliary connecting column is connected with the externally inclined lightning rod through the docking fixed seat. One side of the base is provided with a ground wire connecting groove.

Preferably, the auxiliary connecting columns are distributed at four points, and the outer side of the externally inclined lightning rod box at the top thereof is inclined.

Preferably, an included angle of 45 degrees is maintained between the externally inclined lightning rod and the vertical line of the auxiliary connecting column.

Preferably, the length of the main lightning rod is twice the length of the outer inclined lightning rod.

Preferably, the circular base is fixed on the roof through expansion bolts.

After the above structure is adopted, the beneficial effect of the utility model is that it increases the lightning protection area, and at the same time greatly improves the lightning guiding effect, and can effectively prevent lightning shielding and side lightning strikes.
