Self-heating composite hose for conveying shallow sea thickened oil

The utility model belongs to the technical field of ocean engineering, and relates to a self-heating composite hose for conveying shallow sea thick oil, which comprises an inner pipe, a framework layer, a sealing layer, a compression-resistant layer, a tensile layer, a heat tracing band layer, a heat preservation layer and an outer protection layer which are sequentially arranged from inside to outside. The compression-resistant layer is of a steel tape armored structure, the tensile layer is formed by spirally winding steel bars, and temperature measuring optical fibers are arranged in the heat tracing tape layer. According to the self-heating composite hose, the solid-wall inner pipe is adopted, the roughness of the inner wall of the ocean hose is greatly reduced, friction and shear force in the thickened oil conveying process are reduced, and thickened oil crystallization and sediment accumulation are reduced; meanwhile, the temperature measuring optical fiber in the heat preservation belt can achieve real
