Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline antifreeze technology, specifically an antifreeze device for water conservancy engineering pipelines. Background Technology
[0002] Water conservancy projects refer to engineering projects constructed to prevent and control water-related disasters and to develop and utilize water resources. They mainly include projects related to flood control, drainage, irrigation, water supply, hydropower generation, navigation, water resource protection, and soil and water conservation. Their basic purpose is to control and regulate surface water and groundwater in nature through engineering construction in order to achieve the goals of eliminating harm and promoting benefits.
[0003] Pipelines are widely used in water conservancy projects, so proper management and maintenance of the pipeline system are crucial to ensuring the long-term operation and sustainable development of these projects. However, current water conservancy pipelines are prone to freezing in winter or in some cold regions, which can severely impact construction schedules. Therefore, pipeline insulation is necessary. Existing methods generally involve directly covering the pipeline with an insulation sleeve. However, single-layer insulation cannot perfectly protect the pipeline in severe weather, and freezing is still possible. Furthermore, the length of the insulation sleeve needs to be adjusted according to the pipeline length. To address this, we have designed a water conservancy pipeline antifreeze device.
