[0002] Water conservancy and hydropower are fundamental industries for national economic and social development. In the process of constructing water conservancy and hydropower projects, pipelines are inevitably used. In the cold winter, pipelines located outdoors and not buried in the ground are more vulnerable at the pipe joints and are easily frozen and cracked or the water inside the pipeline freezes into ice. This can cause some water conservancy and hydropower equipment to malfunction or prevent the project from starting, seriously affecting the progress of the work. Therefore, antifreeze devices for water conservancy and hydropower equipment are needed.

[0003] Existing antifreeze equipment typically uses insulation cotton in the insulation layer for insulation and antifreeze operations. Insulation cotton and other materials are easily damaged under long-term wind and sun exposure, reducing the insulation effect and resulting in poor protection. Most existing antifreeze devices are fixed equipment, making it inconvenient to disassemble the insulation layer and replace or adjust it in a timely manner. Therefore, a water conservancy and hydropower equipment antifreeze device with enhanced pipeline connections is needed to improve the above problems. Utility Model Content
