Description

A kind of lightning protection pole

technical field

The utility model relates to the field of electric equipment, in particular to an electric pole capable of lightning protection.

Background technique

A pole is a vertical structure used to erect cables to facilitate long-distance transmission of electricity or telecommunications. Usually, the cables are erected high on the pole so that they can stay away from pedestrians or cross roads and buildings. However, traditional electric poles have no lightning protection measures. In thunderstorm weather, lightning can easily damage transmission lines, which not only easily lead to line tripping and large-scale power outages, but also affect industrial and agricultural production and people's daily electricity consumption, and even endanger the safety of people and livestock beside the line.

The bottom of the support rod is detachably connected to the top of the connection seat, and the connection seat includes a "mouth" shaped seat body. , a through hole is opened at the bottom of the seat body, a push rod is pierced through the through hole, a pressure block and a limit block are respectively provided at the upper end and the lower end of the push rod, and a compression spring is set on the top rod, and the two ends of the compression spring respectively connected to the inner wall of the pressing block and the seat body; the top and bottom ends of at least one of the steel bars are respectively exposed to the top and bottom ends of the pole body, one end of the wire is connected to the exposed end of the top of the steel bar, and the other end of the wire is connected to the exposed end of the top of the steel bar. The support rods are connected.

Further, at least one needle point is provided on the lightning rod.

Further, the bottom of the support rod is provided with a threaded rod, the top of the base body is provided with a hole, and the inner wall of the hole is provided with an internal thread matched with the threaded rod.

Further, a connecting block is provided between the threaded rod and the supporting rod, and a ring is provided at one end of the wire, and the ring is sleeved on the threaded rod.

Further, the pressing block and the limiting block are respectively connected to the push rod by welding, the width of the pressing block is adapted to the inner diameter of the seat body, and the sizes of the pressing block and the limiting block are both larger than the diameter of the through hole.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model is simple in structure and easy to install. The pull-down limit block makes the compression spring in a stretched state, and the seat body is sleeved on the cross arm, and the compression spring drives the pressure block to effectively compress and fix the cross arm and the seat body. The use of compression springs can effectively buffer the seat body and the cross arm, avoiding damage to the lightning protection device due to strong winds or other external factors; the support rod and the seat body are threaded, not only easy to install, but also convenient to transport and carry; the wire passes through The ring is set on the threaded rod. When the threaded rod and the hole are tightened, the connecting block can be driven to press and fix the ring, so that one end of the wire is reliably connected to the support rod; the other end of the wire is connected to the top of the steel bar. The exposed ends are connected, and the bottom end of at least one steel bar is exposed from the bottom end of the pole body, so that the lightning is introduced into the earth through the lightning protection device and the steel bars exposed at both ends of the pole body, effectively ensuring the safety of people and livestock beside the line. Minimize the harm of lightning to industrial and agricultural production and people's daily electricity consumption.
