Fig. 2 is the side structure schematic diagram of wave-type electric generator.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated: the present embodiment is implemented under take technical solutions of the utility model as prerequisite, has provided detailed mode of execution, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1, a kind of wave-type electric generator shown in Figure 2, comprise mechanical module, electric energy conversion module, electricity storage module.
Mechanical module mainly contains buoyancy aid 9, buoyancy bar 10, two magnets 12/14, two coils 13/16, two coil supporters 3/5, dunnage 2, supporting frame 8, two buoyancy bar limit rods 7/17; Electric energy conversion module comprises two rectifier filters 22/23, multiple conducting wires 4/6/21/24; Power storage module comprises storage battery 19, output conductor 20, tutorial light 1.
Wherein, dunnage 2 is fixed on supporting frame 8, and supporting frame 8 is placed in and supports whole electricity generating device in water; Buoyancy bar 10 is fixed on buoyancy aid 9, two buoyancy bar limit rods 7/17 of arranging along buoyancy bar 10 bearing of trends are fixed in dunnage 2, buoyancy bar 10 slides and is arranged in the through hole that forms on described buoyancy bar limit rod 7/17, and two magnets 12/14 are arranged in buoyancy bar 10 along the length bearing of trend of buoyancy bar 10; Two coils 13/16 are placed in coil supporter 3/5, and coil supporter 3/5 is connected on dunnage 2 and arranges equally the setting corresponding to coil 13/16 of described magnet 12/14 along the length bearing of trend of buoyancy bar 10.
This electricity generating device is positioned on sea bed, adjust height, make buoyancy aid 9 float on horizontal plane, wherein buoyancy aid 9 can be selected suitable material and shape (for example illustrated spheroid) to make more to be conducive to fluctuate, magnet 12 and magnet 14 keep certain distance that its magnetic is not interfered with each other, and coil 13 and coil 16 also keep certain distance.
When wave stroke was come, buoyancy aid 9 was subject to floating function and floats, and buoyancy bar 10 moves upward, and when reaching crest, movement travel is maximum.Less at wave, when the range magnet does not go out coil: buoyancy aid 9 for straight line moves upward, makes the buoyancy bar 10 drive magnet 12/14 that moves upward enter coil 13/16 cutting magnetic induction line generation current under buoyancy bar limit rod restriction; Wave will enter trough when wave is fallen after rise by crest, under buoyancy aid 9 self gravitation effects, do straight line and will move downward, and magnet leaves coil cutting magnetic induction line generation current again.Large at wave, when the range magnet passes coil: buoyancy aid 9 moves upward for straight line under the restriction of buoyancy bar limit rod, make buoyancy bar 10 move upward to drive magnet 12/14 to enter coil 13/16 cutting magnetic induction line generation current, the buoyancy bar magnet 12/14 that continues to move upward leaves coil 13/16 cutting magnetic induction line generation current again; Wave will enter trough when wave is fallen after rise by crest, under buoyancy aid 9 self gravitation effects, do straight line and will move downward, and magnet 12/14 enters coil 13/16 cutting magnetic induction line, cutting magnetic induction line generation current, repeatedly generation current again when leaving coil 13/16.
The electric current that makes coil produce by the above motion repeatedly is the Ac that alternately changes, process wire 4/6 is input to the rectifier filter 22/23 with two corresponding connections of coil 13/16, rectifier filter 22/23 can convert Ac to direct current, is transported on the storage battery 19 that is fixed on the dunnage side through wire 21/24 through the electric current after rectifying and wave-filtering; To storage battery 19 charging the time, LED lamp 1 has electric current to pass through and luminous, is used for monitoring the working state of electricity generating device.So just passed through the one-period of wave stroke, along with the impact of wave period, just made the continuous generation current of electricity generating device, through after rectifier filter, electric energy is stored in storage battery.This electricity generating device can high density be distributed in ocean, seabeach, forms a power generation system.
Although the utility model with preferred embodiment openly as above; but it is not to limit claim; any those skilled in the art are not within breaking away from spirit and scope of the present utility model; can make possible change and modification, therefore protection domain of the present utility model should be as the criterion with the scope that the utility model claim is defined.
