Submerged generating device directly utilizing liquid metal magnetic fluid wave energy

A submerged generating device directly utilizing liquid metal magnetic fluid wave energy consists of an outer barrel (1), a piston rod (2), a return spring (13), an inner barrel (3), a piston (4), a main hydraulic cylinder (5), a rigid support (11), a base (12), n (n=1, 2, 3...) hydraulic units and n (n=1, 2, 3...) liquid metal magnetic fluid generators. The outer barrel (1) is coaxial with an inner barrel (3), the inner barrel (3) is fixed on the rigid support (11), the inner barrel (3) is fixedly connected with the rigid support (11) and the base (12), the base (12) is fixed on a seabed, the outer barrel (3) is connected with the piston (4) which is coaxially arranged in the main hydraulic cylinder (5) via the piston rod (2) which is arranged along an central axis of the inner barrel (3), the return spring (13) is sleeved outside the piston rod (2), the main hydraulic cylinder (5), the n hydraulic units and the n liquid metal magnetic fluid generators are arranged in the inner barrel (3), and the whole device is vertically arranged below the sea level.
