The invention provides a multifunctional intelligent protection device for oil extraction equipment, which comprises a bottom mounting table, a swing arm support frame, a rotary locking frame structure, a swing cross beam, a horse head, an oil pumping pull rod, an elastic locking frame structure, an intelligent driving frame structure, a connecting shaft plate, a driving connecting rod, a support base, a reduction gearbox, an input belt wheel, a rotary crank and a counterweight flywheel, the swing arm supporting frames are connected to the front end and the rear end of the left side of the upper portion of the bottom mounting table through bolts. The rotary locking frame structure is installed on the upper portion of the inner side of the swing arm supporting frame. The swing cross beam is arranged on the upper portion of the swing arm supporting frame. The device has the beneficial effects that through the arrangement of the insulating spacer, the armature and the electromagnet, the electromagnet and the armature are matched to drive the transverse conductive plate to move downwards, so that the metal conductive columns on the left side and the right side are disconnected, and the insulating spacer can prevent electrification between the armature and the transverse conductive plate.
