AI Technical Summary
The existing lightning protection devices for cathodic protection of gas pipelines cannot accommodate cathodic protection piles of different diameters, leading to installation difficulties.
A cathodic protection device for gas pipelines was designed. A fixing plate is welded to the outer surface of the cathodic protection pile, and an mounting seat and guide shaft are provided on the fixing plate. A guide sleeve is fitted and a lightning rod is connected. The position of the lightning rod is adjusted by using a threaded rod and a slider to achieve the connection of piles with different diameters.
This allows the lightning rod to flexibly adapt to cathodic protection piles of different diameters, simplifying the installation process and improving the applicability and stability of the device.
