Abstract
A kind of generating equipment, is a kind of alternating current generating means, is realized by the way that the kinetic energy produced in wave flow process is changed into electric energy.Vibration is produced using ocean wave inducing metal coil, causes the magnetic flux through wire coil periodically to change, according to electromagnetic induction principle, you can produce alternating current in wire coil.
Description
1. technical field
The present invention relates to Wave power generation equipment field.Specifically a kind of alternating current generating means.This device flows over wave
The kinetic energy produced in journey changes into electric energy.
2. background technology
When fluid (such as empty gas and water, etc.) bypasses non-streamline object, the object wake flow left and right sides can produce it is paired,
The vortex of be alternately arranged, direction of rotation conversely.This be vortexed is referred to as Karman vortex street.Fig. 1 is Karman vortex street formation schematic diagram.
The structure of vortex in Karman vortex street can be explained with the principle of circular rector conservation.I.e. when a whirlpool from bluff (or
Swirl generating body) boundary layer when coming off, necessarily have the presence in the opposite whirlpool of circular rector therewith.In reality, built when fluid flows through
Karman vortex street can be all produced when building thing, electric wire, bridge pier.At swirl generating body rear, vortex can backward be moved along direction of flow.
Simultaneously because the presence of the circular rector of single vortex, this whirlpool can be by one with flowing the active force in vertical direction, i.e. lift.
Thus in Karman vortex street, fluid can on the direction vertical with direction of flow by periodicity alternation active force.It is theoretical and real
Test all it has been shown that (can be represented under certain condition with the Reynolds number of fluid), the structure of the vortex in Karman vortex street is stable
, thus vortex produces what the relation of frequency and rate of flow of fluid was to determine.Widely used Karman vortex street flowmeter is exactly according to this
What individual principle was made.
If disposing a wire coil in magnetic field, by the relative motion in coil and magnetic field, the magnetic flux through coil can be made
Changing of volume production.According to the law of electromagnetic induction, the change of magnetic flux can make to produce electric current in coil.Periodicity in Karman vortex street
, the power of alternating direction a wire coil being placed in fixed magnetic field can be induced to produce vibration.If this cycle
The vibration of property changes the magnetic flux through wire coil, then alternating current is generated in coil.Fig. 2 is to induce production using vortex
The schematic diagram of raw electric current.
Because the vibration of coil is that the vortex induction being alternately present in Karman vortex street is produced, so this device is known as vehicle
Use swing type generating set.The premise that alternating current is produced using this device is that must have the flowing of fluid, thus the device also may be used
To be considered as one kind of wind energy generating plant.
3. the content of the invention
The invention utilizes above-mentioned background technology, designs a device, and the kinetic energy produced when it flows wave changes into electric energy.
In this arrangement, there is a swirl generating body, its cross section is trapezoidal.Swirl generating body is fixed in a housing.
In a tubular form, two ends are respectively the arrival end and the port of export of fluid to this housing.One rectangular metal coil is arranged on by rotary shaft
In housing.The N poles and S poles of two block permanent magnets are separately mounted in housing, and in the both sides of wire coil.Fig. 3 and figure
4 be vortex induction power generator schematic elevation view and schematic top plan view respectively.Fluid stream crosses the Karman vortex street produced during swirl generating body
Cause the vibration in flow field, so as to drive wire coil to swing, then the magnetic flux in wire coil can into cyclically-varying, so
Alternating current is generated in wire coil.
This apparatus structure is simple, small volume, lightweight, can be considered as the unit of a generating set.In use, allowing many
Individual such generator works together, to produce enough electric energy.

5. embodiment
Below in conjunction with Figure of description and examples of implementation, the present invention will be further described.Examples of implementation：The device is after assembling
Working condition is as shown in Figure 3 and Figure 4.The swirl generating body in trapezoidal section is placed in casing center.The trapezoidal base length of side it is wider one
Side is towards the fluid inlet end of housing, i.e., left side one end in Fig. 3 and Fig. 4.The vortex that the total length of housing should be not less than ten times is sent out
The trapezoidal base length of side of raw body.It is, to entering the guide functions that play of fluid of housing, and to allow behind swirl generating body that it, which is acted on,
Vortex street have a development space.Rotatable wire coil is installed in the trapezoidal base length of side in five times of swirl generating body downstream at a distance.
Two block permanent magnets housing cavity, wire coil both sides.
By the device be placed in certain orientation ocean wave come in flowing, then wave can be by the arrival end of housing, into housing.Stream
Body bypasses swirl generating body, and portion can produce Karman vortex street behind.Vortex in Karman vortex street in pairs, reversely flow through wire coil,
Wire coil produces vibration around rotary shaft.In the case of dead-beat, the magnetic flux through wire coil is fixed.In wire coil
During vibration, generating period changes magnetic flux therewith, then generates alternating current in wire coil.Two terminals of wire coil
Drawn by the aperture on housing.
