A thermal pipeline with external protection function

Abstract

This utility model discloses a thermal pipeline with external protection function. The buffer mechanism includes a first annular frame with an angled top. A telescopic plate is fixedly connected to the bottom of the first annular frame. The telescopic plate is arc-shaped and has a through groove in the middle of its inner wall. A second annular frame is sleeved and slidably connected to the end of the telescopic plate away from the first annular frame. The through groove extends to the end of the telescopic plate inside the second annular frame, and the top of the second annular frame also has an angled top. Threaded mounting holes are provided on the upper sidewalls of both the first and second annular frames, and the two threaded mounting holes are on the same straight line. An anti-collision mechanism is set above the thermal pipeline to isolate and protect it through an upper shield. This prevents construction tools from directly impacting the thermal pipeline during road construction, thus helping to extend the life of the thermal pipeline.
