Problems solved by technology

Lightning conductors have a good effect on preventing direct lightning strikes and induction lightning strikes, but the effect of preventing circumventing lightning strikes is poor. The reason is that in general-purpose tower design, the protection angle of lightning conductors determines the protection range, and the side-phase conductors are at the Near the edge of the protection, it is easy to be hit by lightning strikes. For example, adding a lightning protection line can achieve the effect of expanding the protection range, but the cost is too high

Embodiment 1

[0016] Such as figure 1 , 2 As shown, the lightning rod of the present invention has a needle body 1, an angle steel 2 and an adjustment bolt 7. The angle steel 2 is fixed on the tower head of the power transmission tower by two bolts 6 and grounded, and an adjustment slideway 4 is arranged on the angle steel 2. The adjustment slideway 4 is arc-shaped. The needle body 1 is made of aerospace aluminum. After the tail end of the needle body 1 passes through the adjustment bolt 7, the adjustment bolt 7 is inserted on the adjustment slideway 4 and locked by the adjustment lock nut 3. The tail end of the needle body 1 is fixed on the angle steel 2 with a bolt 5 .

Embodiment 2

[0018] Such as image 3 Shown, the adjustment slideway of the present invention is linear, and all the other are the same as embodiment 1.

Abstract

The invention relates to a lightning rod. The lightning rod comprises a rod body, angle steel and an adjusting bolt, wherein the angle steel is fixed on a tower head of a power transmission iron tower by bolts and is grounded; the angle steel is provided with an adjusting slideway; the adjusting bolt is arranged on the adjusting slideway by adjusting a lock nut; and the tail end of the rod body is fixed by bolts after penetrating through the adjusting bolt. The adjusting slideway is arc-shaped. The adjusting slideway is straight line-shaped. The lightning rod comprises the rod body, the angle steel and the adjusting bolt, the angle steel is fixed on the tower head of the power transmission iron tower by the bolts and is grounded, the angle steel is provided with the adjusting slideway, the adjusting bolt is arranged on the adjusting slideway by adjusting the lock nut, and the tail end of the rod body is fixed by the bolts after penetrating through the adjusting bolt. An angle of protection can be adjusted through the adjusting bolt, so that the protective range of a lightning conductor is widened, the problem that circle lightning poses a threat to the iron tower and insulators and conducting wires thereof is solved, and the iron tower and the insulators and conducting wires thereof are effectively protected.

Description

technical field [0001] The invention relates to a lightning rod. Background technique [0002] At present, known iron towers are equipped with one or two lightning protection wires to prevent direct lightning strikes, induction lightning strikes and circumventing lightning strikes. Lightning conductors are effective in preventing direct lightning strikes and induction lightning strikes, but are less effective in preventing circumventing lightning strikes. The reason is that in the design of general iron towers, the protection angle of lightning conductors determines the protection range. Near the edge of the protection, it is easy to be hit by lightning strikes. For example, adding a lightning conductor can achieve the effect of expanding the protection range, but the cost is too high. To prevent iron towers and their insulator wires from being struck by shielding lightning, there is an urgent need for a lightning conductor with low cost and good lightning protection effect...
