In this way, the buoyancy of seawater is indirectly converted into the potential energy of the weight 16 and the hydraulic energy of the jacking hydraulic cylinder 14 .

Similarly, when the introduction oil pipe 17P is opened by the hydraulic solenoid valve 17S, the weight of the weight block 16 itself will force the support piston rod 141 to retract into the cylinder body of the top support hydraulic cylinder 14, so that the top support hydraulic cylinder 14 The oil inside is sent to the hydraulic generator 17G from the introduction oil pipe 17P. In this way, the continuously flowing liquid oil can drive the hydraulic generator 17G to generate electricity. In other words, the potential energy of the weight block 16 and the hydraulic energy of the jacking hydraulic cylinder 14 are both converted into electrical energy.
