[0023] The locking device includes a fixed block 4, which is fixedly installed on the side wall of the pipe section 1. The interior of the fixed block 4 is rotatably connected to a rotating block 5 via a rotating shaft. A threaded column 6 is fixedly connected to one side of the rotating block 5. The external thread of the threaded column 6 is connected to a fastening ring block 8. The top of the fastening ring block 8 is fixedly connected to an arc rod 9. The threaded column 6 is located inside the U-shaped groove 7, and the fastening ring block 8 is tightly pressed against the surface of the annular convex edge 14.

[0024] It is worth mentioning that the pipe section 1, the annular flange 14 and the reinforcement strip 3 are all made of polymer composite materials.
