[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides the following embodiments: Figures 1-4 As shown, the pipeline corrosion protection structure includes protective covers 3 and corrosion protection mechanisms at the connections. Two sets of four connecting flanges 2 are fixedly connected to the outer sides of both ends of the two pipeline bodies 1. The two pipeline bodies 1 can be aligned and connected via the two connecting flanges 2. The two protective covers 3, when engaged, cover the pipe wall of the pipeline body 1 to form a protective mechanism, providing protection to the outer side of the pipeline body 1. Additionally, a protective pad, made of rubber, can be added between the pipeline body 1 and the protective covers 3 to enhance the protective effect. Upper seat 4 is slidably installed on the outer top of two adjacent connecting flanges 2, and lower seat 5 is slidably installed on the outer bottom of two adjacent connecting flanges 2. After the upper seat 4 and lower seat 5 are assembled, the end of the protective cover 3 can be clamped and fixed, and the pipe body 1 and the protective cover 3 can be replaced. The upper seat 4 and lower seat 5 are movably installed through the installation assembly to facilitate the assembly and fixing between the upper seat 4 and lower seat 5. The inner sides of the upper seat 4 and lower seat 5 are respectively provided with clamping assemblies to facilitate the fixed clamping between two adjacent connecting flanges 2. The installation assembly includes two sets of six threaded holes 8 opened on the lower surface of both ends of the upper seat 4. The two ends of the top of the lower seat 5 are respectively fixedly connected to the connecting blocks 10. Three screw rods 9 are evenly inserted through the inner bottom of the connecting blocks 10. The top ends of the three screw rods 9 are respectively threaded into the inner side of the two sets of threaded holes 8 at the bottom of the upper seat 4. The threaded part of the screw rod 9 is related to the threaded connection between the connecting blocks 10 and the threaded holes 8, realizing the upper seat 4 on the lower seat 5. The clamping assembly includes two clamping plates 6 that are slidably installed via a limiting assembly, which can clamp two adjacent connecting flanges 2. Three limiting sleeves 12 are evenly fixedly installed on the side of the clamping plate 6 away from the connecting flange 2, which can reduce the wear of the threaded push rod 7 on the clamping plate 6. The threaded push rod 7 is installed on the inner thread of the three limiting sleeves 12, which can push the threaded push rod 7 to move towards the connecting flange 2 and squeeze the clamping plate 6 to clamp the connecting flange 2. The upper seat 4 and the lower seat 5 are respectively provided with through holes corresponding to the positions of the limiting sleeves 12. The threaded push rod 7 is rotatably installed in the through holes via bearings to facilitate the rotation installation of the threaded push rod 7.
