Wherein the floating body 7 provides buoyancy for the whole device, and the size and the position of the floating body 7 can be adjusted to adjust the submerging depth of the rotor 10 in water. The size and shape of the float 7 may be designed to provide appropriate buoyancy and damping forces as required by the hydrodynamic characteristics of the device. The upper air guide sleeve 6, the stator iron core 2 and the lower air guide sleeve 11 are connected together through a stud 9 and a nut 8, the lower air guide sleeve 11 is connected with an anchor chain 13 through an anchor chain connecting ring 12 attached to the lower air guide sleeve 11, the anchor chain 13 is fixed to the sea bottom through anchors or other forms, the lower air guide sleeve 11 and the upper air guide sleeve 6 can be designed in size and shape as required, the coil 3 is installed on the stator iron core 2, the permanent magnet 4 is fixed to the outer wall of the rotor 10, the number of the blades 1 is multiple, and the outer edges of the blades are fixedly installed on the inner wall of the rotor 10.
