The lightning rod overcomes the defects that the existing lightning rod for preventing shielding failure is small in protection range and complex in installation and disassembly. The lightning rod is locked by a clamping type locking mechanism, lightning rod receiving rods are uniformly distributed on the outer edge of the ground wire clamp, and each lightning rod receiving rod is fixed on the ground wire clamp cover through bolts.

Description

Lightning rod for preventing shielding failure
Technical Field
The invention relates to the technical field of lightning conductors of power transmission lines, in particular to a lightning rod capable of preventing shielding failure.
Background
Overhead transmission lines are generally provided with lightning conductors along the lines to resist direct lightning. However, the lightning conductor cannot ensure that the protected wire below is not hit by the direct lightning, and the shielding failure rate of part of lines is seriously higher due to the reasons of landform, design and the like. The anti-shielding failure lightning rod is arranged at the key position of the overhead ground wire, so that the line shielding failure rate can be greatly reduced, but the existing anti-shielding failure lightning rod is not widely applied due to the complex installation and disassembly and limited protection range.
Disclosure of Invention
The invention aims to provide an anti-shielding failure lightning rod which is wide in protection range and convenient to install and disassemble, aiming at the defects that the existing anti-shielding failure lightning rod is small in protection range and complex in installation and disassembly.
The invention specifically adopts the following technical scheme:
the utility model provides an anti-shielding failure lightning rod, includes ground wire anchor clamps lid, and the center of ground wire anchor clamps lid is equipped with the ground wire hole, ground wire anchor clamps lid is including looks articulated ground wire anchor clamps upper cover and ground wire anchor clamps lower cover, and the portion that opens and shuts of ground wire anchor clamps upper cover and ground wire anchor clamps lower cover is locked through buckle formula locking mechanism, the outer edge evenly distributed of ground wire anchor clamps has the lightning rod that connects.
Preferably, the ground wire hole is located at the junction of the upper cover of the ground wire clamp and the lower cover of the ground wire clamp.
Preferably, the top end of the lightning rod is conical, and the top end of the lightning rod extends to the outer side of the ground wire clamp cover.
Preferably, the ground clamp cover is in the shape of a regular hexagon.
Preferably, the number of the lightning receiving needle rods is three, each lightning receiving needle rod is 30cm in length and is symmetrically distributed at 120 degrees with each other.
Preferably, one of the lightning receiving needle rods is vertically arranged upwards, and the other two lightning receiving needle rods are horizontally arranged at a position 30 degrees lower than the other lightning receiving needle rods.
Preferably, each lightning rod is fixed on the ground wire clamp cover through a bolt.
Preferably, the surface of the ground wire hole is covered with conductive rubber.
Preferably, the ground clamp upper cover and the ground clamp lower cover are hinged through a connecting shaft.
The invention has the following beneficial effects: one end of the upper cover and the lower cover of the ground wire clamp are hinged, the opening and closing part is locked through a buckle type locking mechanism, the installation and the disassembly are very convenient, the ground wire clamp can be installed, disassembled and shifted by adopting special disassembly integrated equipment, and the installation and the disassembly are very convenient;
the lightning rod adopts the structure setting of symmetric distribution, can avoid general single-needle, double-needle structure lightning rod because ageing not hard up protection inefficacy that leads to, can guarantee the lightning rod connect the sudden strain of a muscle scope, can avoid general single-needle, double-needle structure lightning rod because ageing not hard up protection inefficacy that leads to, thereby can guarantee the lightning rod connect the sudden strain of a muscle scope and ensure lightning rod long-term steady operation.
Drawings
Fig. 1 is a schematic view of the overall structure of the lightning rod;
fig. 2 is a snap-in locking mechanism configuration.
Wherein, 1 is an upper cover of the ground wire clamp, 2 is a lower cover of the ground wire clamp, and 3 is conductive rubber; 4 is a buckle type locking mechanism, 5 is a lightning rod, 6 is a connecting shaft, 7 is a bolt, and 8 is a ground wire.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1 and 2, the lightning rod for preventing shielding failure comprises a ground wire clamp cover 1, a ground wire hole is formed in the center of the ground wire clamp cover, conductive rubber 3 covers the surface of the ground wire hole, the ground wire hole is formed in the joint of the ground wire clamp upper cover 1 and the ground wire clamp lower cover 2, the opening and closing parts of the ground wire clamp upper cover 1 and the ground wire clamp lower cover 2 are locked through a clamping type locking mechanism 4, lightning rod receiving rods 5 are uniformly distributed on the outer edge of the ground wire clamp, and each lightning rod receiving rod 5 is fixed on the ground wire clamp cover through a bolt 7.
The top end of the lightning rod 5 is conical, and the top end of the lightning rod extends to the outer side of the ground wire clamp cover.
Ground wire anchor clamps lid is regular hexagon, and lightning receiving needle bar quantity is three, and every length is 30cm, is 120 symmetric distribution each other, one of them lightning receiving needle bar sets up perpendicularly upwards, and other two difference levels are 30 orientation settings under the one side.
The upper cover of the ground wire clamp and the lower cover of the ground wire clamp are hinged through a connecting shaft 6.
When the lightning rod is used, the lightning rod is additionally held on a ground wire 8, wherein the ground wire is positioned in a ground wire hole, and the conductive rubber in the ground wire hole plays roles of protecting a lead and damping vibration.
The shielding failure prevention lightning rod is arranged at a point position with a higher shielding failure rate in the direction from a lightning conductor gear of an overhead line, and is usually arranged at a position 10-50 m away from a tower, so that the shielding failure rate of the whole line can be greatly reduced.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
