Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically to a rotary fire protection pipe. Background Technology

[0002] Firefighting pipelines refer to pipeline equipment used in firefighting to connect firefighting equipment and materials and transport firefighting water. Firefighting pipelines are directly connected to the fire water source. In use, firefighting water can be quickly transmitted from the pipeline and injected into the fire water tank of the fire truck through the curved pipe. Compared with the traditional method of connecting the fire water tank through fire hydrants and fire hoses, adding firefighting water through firefighting pipelines can reduce the impact of water pressure when the water level in the tank is high, making the firefighting water addition speed faster. At the same time, firefighting pipelines have good pressure resistance, corrosion resistance and high temperature resistance to cope with the harsh environment during a fire.

[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: existing fire-fighting pipelines are fixed and locked together by multiple separate fire-fighting pipe fittings, thus fixing their extension angle and transmission angle. When fire trucks are adding water, they often need to move to a designated position to align the fire-fighting pipeline with the water tank's inlet. When it is necessary to adjust the alignment position of the fire-fighting pipeline end, it cannot be adjusted directly. It is necessary to adjust the alignment position by using a flexible hose or additional connecting separate pipe fittings. The adjustment steps are cumbersome and time-consuming, resulting in poor adaptability of the fire-fighting pipeline. Utility Model Content
