The invention provides an automatic passive cable winding device. A spring type spring is used as power for winding a cable, when the cable is pulled out, the spring type spring is tensioned for energy storage, when the cable is loosened, the spring type spring releases energy to drive a rotating barrel to rotate to automatically wind the cable, the synchronous performance is good, electric energy drive is not needed, the cable take-up and pay-off efficiency is high, take-up and pay-off are reliable, and the automatic passive cable winding device can be suitable for any installing position. An electric brush and a slip ring are matched and communicated inside the rotating barrel, the slip ring is made of a high-melting-point brass material, and the electric brush is made of a mixture material of copper with a higher melting point and graphite. The automatic passive cable winding device can serve as a lifting equipment take-up and pay-off device and a lightning stroke current release device, and is wide in app
