The invention relates to an automatic lifting floating type integrated flexible net cage. The integrated flexible net cage comprises an upper floating frame assembly; the upper floating frame assemblyis of a circular or polygonal rigid structure and floats on water surface through a floating body; multiple automatic lifting devices are arranged at different positions of the upper floating frame assembly and include mounting brackets, winch wheels arranged on the mounting brackets and motors, the winch wheels are wrapped with pulling ropes, and output shafts of the motors are coaxially connected with the winch wheels; the lower ends of the pulling ropes are connected with connecting ropes, the connecting ropes are fixedly connected to a purse seine, and the purse seine is of a flexible structure; the purse seine is fixedly connected with a lower supporting assembly, the lower portion of the lower supporting assembly is connected with an anchor, and the anchor sinks into the bottom of awater body. The adoption of the automatic lifting floating type flexible net cage, on the one hand, can buffer the rigid impact of waves, and on the other hand, can solve disasters caused by bad seaconditions to aquaculture by lifting the purse seine. At the same time, the manufacturing cost of the net cage is reduced, and the mechanical automatic lifting solves the problems of deep sea super large flexible net cages.
