Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline anti-freezing, in particular to an anti-freezing device for water conservancy project pipelines. Background Technique
[0002] The water conservancy project pipeline refers to the pipeline system used for conveying water flow in water conservancy projects. This pipeline system is usually used for water supply, drainage, irrigation, and water resource utilization, etc. The water conservancy project pipeline plays an important role in water resource management and utilization, and can effectively meet people's water use needs, prevent floods, and improve farmland productivity. At the same time, reasonable management and maintenance of the pipeline system are also the keys to ensuring its long-term operation and sustainable development. When the temperature around the pipeline system is relatively low, the low temperature affects the water conveyance efficiency of the pipeline and even damages the pipeline. It is necessary to prevent freezing on the pipeline surface. However, currently, generally, a heat preservation cylinder is used to heat and prevent freezing on the pipeline surface. When ice layers are generated on the pipeline surface, the ice layers weaken the heat conduction effect of the heat preservation cylinder, resulting in a decrease in the heating efficiency of the heat preservation cylinder, thus affecting the anti-freezing efficiency. For this reason, we propose an anti-freezing device for water conservancy project pipelines. Content of the Utility Model
