Abstract
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.
Description
Technical field
The present invention relates to the floated hollow magnetic group of one in a kind of buoyant raft Wave power generation device, coordinate with cylindrical layer winding winding and can form drum type brake ocean wave generator.
Background technology
Relevant Wave power generation device has thousands of kinds of patented inventions at present, the common feature of these patents is all the kinetic energy of wave is changed into multi-form mechanical energy by servicing units such as machinery or hydraulic pressure such as various gear, tooth bar, levers drive electrical power generators, cause Blast Furnace Top Gas Recovery Turbine Unit (TRT) complicated integral structure, manufacture and installation cost high, be difficult to popularize application.Buoyant raft Wave power generation device generator adopts cylindrical structure, cylindrical layer winding winding is hung on buoyant raft, realize moving up and down under the effect of wave, but ebb tide again due to seawater flood tide every day and form the tidal range of several meters high, magnet is difficult to fixing a certain position in the seawater, and cylindrical layer winding winding is difficult to form effective relative motion with magnet.
Summary of the invention
The problem of fixing a certain position is in the seawater difficult in order to solve buoyant raft Wave power generation device magnet, the invention provides a kind of floated hollow magnetic group, the relative motion realizing speed with cylindrical layer winding winding and superpose can be suspended in the cavity in cylindrical layer winding winding stroke.
The technical solution used in the present invention is: permanent magnet layering loaded in hollow magnetic skeleton, and fill plastic mattress between each layer there, in hollow magnetic skeleton top and bottom, O-ring seal and plastic dome are installed, are fixed by fastening bolt and form floated hollow magnetic group together.The overall proportion of floated hollow magnetic group is less than the proportion of seawater, plastic dome on hollow magnetic skeleton there is a screwed hole, above screwed hole, having sealing ring and bolt, for injecting appropriate seawater under generator during water, the overall proportion that floated hollow magnetic group comprises sealing ring and bolt is adjusted to the proportion equaling seawater.Floated hollow magnetic is assembled in cylindrical layer winding winding, then cylindrical layer winding winding is hung over raft and form a kind of buoyant raft Wave power generation device with it.Cylindrical layer winding winding in this device is when rising fast with wave or decline, always floated hollow magnetic group has little time to change the direction of motion, both will produce the superposition of the contrary speed of the direction of motion.The motion of this high-frequency cutting magnetic line can produce induced electromotive force in cylindrical layer winding winding.
The invention has the beneficial effects as follows: structure is simple, easy for installation, with low cost.

Embodiment
With injection molding machine of plastic injection moulding hollow magnetic skeleton (2) and plastic dome (4) and plastic mattress (6), multiple gusset is had between magnetic group skeleton (2) inner and outer ring, the equally distributed space of multiple equal and opposite in direction will be divided between two rings, by permanent magnet (1) layered mosaics of customization in space, fill plastic mattress (6) between every layer and its pole orientation one glue of applying is fixed, O-ring seal (5) and plastic dome (4) fastening bolt (3) are then installed respectively in hollow magnetic skeleton (2) top and bottom fix, form floated hollow magnetic group (G).Floated hollow magnetic group (G) is loaded the inner chamber of cylindrical layer winding winding (H), open bolt (7) to inject appropriate seawater by screwed hole the overall proportion that floated hollow magnetic group (G) comprises bolt (7) and sealing ring (8) is adjusted to the proportion equaling seawater, make floated hollow magnetic group (G) can not rise fast in the seawater and can not sink to being advisable fast.Cylindrical layer winding winding (H) is hung over a kind of buoyant raft Wave power generation device of the upper composition of floating body (L) by lifting rope (E).Cylindrical layer winding winding (H) in this device is when rising fast with wave, be suspended in floated hollow magnetic group (G) in cylindrical layer winding winding (H) inner chamber by seawater drag effects movement velocity much smaller than cylindrical layer winding winding (H), the bottom of cylindrical layer winding winding (H) can be moved to very soon, if the height of wave is much larger than the length of cylindrical layer winding winding (H), now floated hollow magnetic group (G) is identical with direction with the movement velocity of cylindrical layer winding winding (H), and when the moment that cylindrical layer winding winding (H) the flip-flop direction of motion falls after rise fast, floated hollow magnetic group (G) has little time to change the direction of motion, still motion state is upwards remain at effect lower suspension hollow magnetic group (G) of inertia force, this is superposing of a kind of speed for cylindrical layer winding winding (H) with floated hollow magnetic group (G), conversely when cylindrical layer winding winding (H) moves upward, this phenomenon still exists.According to Faraday's electromagnetic induction law, the induced electromotive force E=BLv produced in cylindrical layer winding winding (H), under the condition that B and L is certain, speed v is the single factor determining induced electromotive force size, and therefore the superposition of speed can significantly improve the operating efficiency of drum type brake generator.
