Preferably, the top of the generating device 3-7 is mounted on the top end of the inner part of the mounting box 3-10 through a lifting appliance 3-4, so as to ensure that the generating device 3-7 is always vertically arranged when the mounting box 10 swings and deflects under the action of water impact, and as a further preference, the lifting appliance 3-4 in this embodiment is flexible soft lines or fixed hard rods.
