Description

Technical Field

[0001] The utility model relates to the technical field of main steam pipelines, in particular to a main steam pipeline displacement monitoring device. Background Art

[0002] As the carrier of steam circulation, the main steam pipeline is one of the devices for transporting steam. The main steam pipeline is the trunk pipeline used to transport steam.

[0003] After searching, the applicant discovered a Chinese patent application titled "A New Main Steam Pipeline Displacement Monitoring Device," with publication (announcement) number "CN220398475U." This patent utilizes a support ring and a bottom box. The bottom box is installed below the main steam pipe body, and the support ring abuts against the bottom surface of the main steam pipe body, enabling full-scale displacement monitoring of the main steam pipe body. The device is compact, flexible, and easy to move and use. It is mounted directly on the bottom of the main steam pipe body, offering quick, easy installation, comprehensive monitoring, and exceptional ease of use.

[0004] During the use of the main steam pipeline, since it needs to connect multiple branch pipes, the stability of its position needs to be guaranteed. Otherwise, the stability of the branch pipe connection will be affected, and even the branch pipe connection position will become loose and leak. In order to avoid the above problems, it is necessary to monitor the displacement of the main steam pipeline. However, the existing detection structure can only monitor one side of the main steam pipeline and cannot reflect the displacement of the main steam pipeline on all sides. This will affect the accuracy of the main steam pipeline displacement monitoring and reduce the performance of the main steam pipeline displacement monitoring device. Utility Model Content

The push plate 5 drives the movement of the measuring cone block 10 through the longitudinal rod 8, which can be reflected in real time on the scale plate 11. After the installation is completed, the scale indicated by the measuring cone block 10 on each scale plate 11 is recorded for future comparison, thereby ensuring the monitoring effect of the pipeline displacement.
