Preferably, the section of the wrap-type anti-falling device is U-shaped, C-shaped or V-shaped.
Preferably, the wrap-around fall arrest device is a tire-like structure formed from a plurality of arcuate channel structures connected circumferentially.
Preferably, the wrap-around fall arrest device comprises a two, three or four arcuate slot arrangement.
Preferably, the end of each groove structure is provided with a square plate with bolt holes, and the adjacent groove structures are fixed by bolts passing through the square plates with the bolt holes.
Preferably, the wrap-around anti-falling device is radially spaced from the lightning rod body, the needle mount/ground post and is not directly connected.
Preferably, a plurality of stiffening plates for fixing the flange plate and the lightning rod body are arranged on the flange plate, and the wrap-type anti-falling device wraps the periphery of the stiffening plates.
Preferably, the stiffening plate comprises two right-angle edges, one of which is welded to the flange and the other of which is welded to the lightning rod body or the needle base/ground post.
Compared with the prior art, the invention has the following advantages:
according to the transformer substation lightning rod, the wrapped anti-falling device is arranged outside the flange, so that the wrapped anti-falling device can wrap the flange, separation of the two flanges is effectively limited, the upper lightning rod body and the lower base or the ground wire column are effectively prevented from being separated from each other at the flange after fatigue failure of the flange bolts, and falling down of the lightning rod can be prevented. Simple structure, convenient to use can avoid the lightning rod empting to fall, avoids the lightning rod to empty to fall and smashes bad adjacent equipment and causes the secondary loss.
