This utility model discloses a backflow prevention safety protection device for oil production systems, relating to the technical field of oil production systems. It includes: an active component, a driven component, and a backflow prevention assembly. The active component has a cavity. The backflow prevention assembly is installed within the cavity. One end of the driven component is installed within the cavity. The backflow prevention assembly includes: two swing blocks, two springs, and two friction plates. The two swing blocks are rotatably connected to the active component. The two ends of the two springs are fixedly connected to the two swing blocks. The two friction plates are fixedly installed on the outer arc surfaces of the two swing blocks. Under the action of the backflow prevention assembly, when the motor drives the active component to rotate, the two swing blocks, under the action of centrifugal force, stretch the two springs, causing the friction plates to contact the friction rings. Under the action of friction, the driven component begins to rotate synchronously with the active component. When the motor stops, the oil pump cannot drive the motor to rotate, thus improving the safety and dexterity of the protection device.
