Lightning conductor conductor detection device for fan blade

The lightning conductor detection device comprises an unmanned aerial vehicle, a cover body and a lightning conductor detector, an upward opening is formed in the cover body, the side, away from the opening, of the cover body is connected with the unmanned aerial vehicle, and the lightning conductor detector is provided with a first detection line and a second detection line. The connector of the first detection line is used for being connected with the blade root of the blade, the second detection line extends into the opening of the cover body, and the connector of the second detection line is used for abutting against a lightning arrester arranged on the blade tip when the cover body covers the blade tip of the blade. An operator can control the unmanned aerial vehicle to fly to the blade tip of the blade, align the cover body to the blade tip and make the connector located in the opening of the cover body abut against the blade tip, so that detection of the lightning conductor of the fan blade is achieved
