Description

Technical Field

[0001] The utility model relates to the technical field of instrument protection boxes, in particular to an instrument protection box used for a high-altitude platform. Background Art

[0002] At present, large-diameter gas pipelines in factories are usually arranged in high-altitude pipe galleries. When using insertion flow meters to measure pipeline flow, the insertion flow meters are also placed on high-altitude platforms. At the same time, instrument protection boxes are required to protect the insertion flow meters, and the insertion flow meters need to be cleaned and purged regularly. When cleaning and purging, the insertion flow meter needs to be pulled out to clean the probe of the insertion flow meter. The length of the probe is about two meters, and the traditional instrument protection box is fixed on the platform, which makes it difficult to plug and unplug the insertion flow meter. Therefore, the entire instrument protection box needs to be dismantled to pull out the probe. However, the traditional instrument protection box is not only difficult to dismantle, but also there is a risk of falling when dismantling at high altitude. In addition, the removal of the traditional instrument protection box takes a long time, which will also affect the measurement of pipeline nodes. Utility Model Content
