Description

Technical Field

[0001] The utility model relates to the technical field of pipeline antifreeze, in particular to a water conservancy project pipeline antifreeze device. Background Art

[0002] The main purpose of the antifreeze device for water conservancy project pipelines is to prevent the freezing and rupture of pipelines in cold environments and ensure the normal operation of pipelines. It is usually composed of insulation materials and protective layers, which can effectively reduce the heat exchange between the pipeline and the external environment, thereby reducing the temperature drop rate inside the pipeline and preventing or delaying freezing.

[0003] When preventing freezing of existing water conservancy project pipelines, generally, a thermal insulation sleeve is directly put on the outer end of the pipeline for thermal insulation protection of the pipeline. However, when the pipeline is in a low temperature environment, the effect of a single-layer thermal insulation sleeve is limited, and it is not convenient to perform physical anti-collision and impact protection on the pipeline in the cold. For this reason, we propose a water conservancy project pipeline anti-freezing device. Utility Model Content
