The invention relates to a
lightning protection
lightning receiving rod detection connecting device,
system and method. The connecting device comprises a sleeve and a connecting mechanism. The sleeveis used for sleeving and being fixed on a
lightning receiving rod, the connecting mechanism comprises a conductive part and a motor used for driving the conductive part to move, the motor is providedwith an electric
brush conductively connected with the conductive part, the electric
brush is conductively connected with a test wire, and the ground end of the test wire is connected with a
ground resistance tester; part or all of the conductive part is arranged in the sleeve, the conductive part can remove the insulating layer on the surface of the lightning receiving rod during movement, and the part, located in the sleeve, of the conductive part can be effectively and conductively connected with the lightning receiving rod. When the connecting
system is used for lightning protection detection of the lightning receiving rod, the connecting device and the
test line are carried by the unmanned aerial vehicle. The sleeve is sleeved on the lightning receiving rod, the connecting mechanism can be effectively connected with the lightning receiving rod, and the connecting mechanism is conductively connected with the test wire, so that the connection between the lightning receiving rod andthe
grounding resistance tester can be firmer through the connecting
system.
