Description

Technical Field

[0001] The present invention relates to the technical field of gas detection, and in particular to a granary temperature and gas measurement integrated detection device. Background Art

[0002] In recent years, with the implementation of the grain system storage and expansion plan, a large number of grain storage silos have been planned and built. The silo is a carrier for storing grain. During storage, the gas inside the silo needs to be tested to ensure the quality of the storage environment. Generally speaking, grain stored for a long time will generate more gas. It is necessary to install gas concentration detection tubes in the silo to regularly test the concentrations of gases such as phosphine, oxygen and carbon dioxide in the silo.

[0003] In the current practice of granary gas detection operations, the problem of difficulty in laying out gas concentration detection tubes is often encountered, especially in large-diameter silos with high grain loading lines ranging from 20 meters to 45 meters. Manually laying detection tubes can only be laid to about 9 meters, and the workload is large, which is difficult to meet actual needs. In special situations such as half-warehouse, gas detection tubes cannot be laid, affecting normal grain storage and grain storage safety. For this reason, a granary temperature and gas measurement integrated detection device is proposed. Summary of the Invention
