Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting, in particular to a fire fighting water channel heating device for a fire fighting vehicle in cold regions. Background Art

[0002] The fire water system for cold-region fire trucks refers to the water system on fire trucks used in cold regions, which is designed to provide the water pressure and flow required for firefighting operations to extinguish fires and rescue. The water system needs to be able to work normally in a low-temperature environment to prevent the water system from freezing or icing to ensure the smooth progress of firefighting operations.

[0003] The fire water circuits used in fire trucks in cold regions in the prior art are prone to freezing of fire water due to low temperatures, especially at the water outlet pipes connected to the water pumps. The existing methods for preventing freezing of fire water circuits used in cold regions are mostly to wrap the surface of the fire water pipes with an insulation layer. This method has poor effect in extremely cold regions and is likely to affect the normal water use of fire trucks, delaying the best time to extinguish fires. At the same time, when the fire truck is not in use, water is likely to remain in the fire water circuit, which is likely to cause freezing in the water pipes in cold regions, affecting the water output of the water pumps and the progress of firefighting operations.

[0004] To this end, we provide a fire water line heating device for cold area fire trucks to solve the above problems. Utility Model Content
