Leakage-proof pipeline protection assembly

The utility model provides a leakage-proof pipeline protection assembly, and relates to the technical field of petroleum pipelines. The left end surface and the right end surface of the mounting seat are symmetrically and fixedly connected with two mounting plates; four fixed insertion rods are slidably connected to the centers of the interiors of the four mounting plates; the front part and the rear part of the top end surface of the mounting seat are symmetrically and fixedly connected with a group of support frames; the top end faces of the two sets of supporting frames are each fixedly connected with a lower arc-shaped base plate. When leakage occurs at the joint of the petroleum pipeline, petroleum leaked at the joint of the petroleum pipeline can be blocked and limited to spread through the upper oil conveying sliding groove and the lower oil conveying sliding groove, and meanwhile the leaked petroleum can be collected through the upper oil conveying sliding groove and the lower oil conveying sliding gr
