[0002] At present, there are thousands of patented inventions related to wave power generation devices. The common feature of these patents is that the kinetic energy of waves is converted into different forms of mechanical energy through various gears, racks, levers and other mechanical or hydraulic auxiliary devices to drive generators to generate electricity. As a result, the overall structure of the power generation device is complex, the cost of manufacturing and installation is high, and it is difficult to promote and popularize the application
The generator of the floating raft wave power generation device adopts a cylindrical structure, and the cylindrical coil winding is hung on the floating raft to realize up and down movement under the action of the waves. Fixed at a certain position in seawater, it is difficult for the cylindrical coil winding to form effective relative motion with the magnet

Embodiment Construction
[0011] Use a plastic injection molding machine to inject the hollow magnetic frame (2), the plastic dome (4) and the plastic pad (6). Spaces of equal size and uniform distribution, inlaid custom-made permanent magnets (1) layered in the space, a plastic pad (6) is placed between each layer and the direction of the magnetic poles is fixed with glue, and then the hollow magnetic skeleton (2) The sealing rubber ring (5) and the plastic dome (4) are respectively installed on the upper and lower sides and fixed with fastening bolts (3) to form a suspended hollow magnetic group (G). Put the suspended hollow magnetic group (G) into the inner cavity of the cylindrical coil winding (H), open the bolt (7) and inject an appropriate amount of seawater through the threaded hole to put the suspended hollow magnetic group (G) including the bolt (7) and seal The overall specific gravity of circle (8) is adjusted to be equal to the specific gravity of seawater, so that it is advisable that the...

The invention provides a suspension type hollow magnetic group which is used for a floating raft wave power generation device. The suspension type hollow magnetic group is mainly composed of permanent magnets and a hollow magnetic group framework. A threaded hole covers the suspension type hollow magnetic group. Sealing rings and bolts are arranged above the threaded hole and are used for injection of proper amount of seawater when a power generator enters the water. The whole specific gravity of the suspension type hollow magnetic group including the sealing rings and the bolts is adjusted to be equal to the specific gravity of seawater so that the suspension type hollow magnetic group is enabled to be suspended in a coil winding without rapid rising or rapid sinking. When the cylindrical coil winding rapidly rises or falls along with sea waves, the suspension type hollow magnetic group is always late to change movement direction so that superposition of speed of opposite movement directions of the cylindrical coil winding and the suspension type hollow magnetic group can be generated. According to the law of electromagnetic induction, induced electromotive force generated in the cylindrical coil winding is E=BLv, and speed v is the only factor determining the size of the induced electromotive force under the condition that B and L are certain so that working efficiency of the cylindrical power generator can be substantially enhanced by superposition of speed.
