Description

Technical Field

[0001] This utility model relates to the field of pipeline monitoring technology, specifically to a high-pressure steam pipeline displacement monitoring device. Background Technology

[0002] High-pressure steam flows through high-pressure steam pipelines. The high-pressure steam will cause the high-pressure steam pipelines to expand thermally. Thermal expansion is generally divided into front-back, left-right, and up-down directions. The amount of expansion in these three directions needs to be monitored.

[0003] For example, Chinese patent CN220818895U describes a real-time displacement monitoring device for detecting the expansion of four tubes in a boiler. It includes a wireless laser displacement monitor and an adjustment box fixedly connected to the monitor. Slide plates are slidably connected to both sides of the adjustment box, and clamping components are fixedly connected to the slide plates to clamp the pipes. The adjustment box is equipped with a power box and a threaded rod with opposite threads connected to it. The threads on both sides of the threaded rod are in opposite directions, and each side is threadedly connected to a slide plate, allowing the slide plates to move closer or further apart under the power of the power box. This invention provides a convenient detection device for installation and disassembly; it eliminates the need for periodic manual inspection, saving manpower; and it provides real-time feedback of detection information, improving work efficiency.

[0004] However, the above structure can only monitor the expansion in one direction and cannot monitor in all directions. In addition, it is easily moved by the external environment when monitoring outdoors. Furthermore, when the pipeline is long, the use and maintenance costs of power lines and communication cables are high.

[0005] Based on this, the present invention designs a high-pressure steam pipeline displacement monitoring device to solve the above problems. Utility Model Content
