Abstract
Disclosed is a vortex induction power generator. The utility model relates to novel power generation equipment, in particular to an AC generation device which is realized by converting kinetic energy generated in the fluid flow process into electric energy. When the fluid passes through a non-streamline body, pairs of vortexes that are generated behind the non-streamline body, are arranged alternately and have opposite rotating directions, namely the Kaman vortex street can be formed. The pressure along the flow direction of the fluid in the Kaman vortex street can be alternately changed. The alternately-changed pressure field can induce an object placed therein to generate the periodical oscillation. If the Kaman vortex street is generated in the magnetic field, the vortex can induce a metal coil to generate oscillation so as to cause the periodical change of the magnetic flux of the metal coil, namely, the alternating current can be generated in the metal coil according to the electromagnetic induction principle. The vortex induction power generator is mainly used for generating power at the place with the wind field or is arranged on a moving carrier for generating power.
Description
1. technical field
The present invention relates to field of generating equipment.It specifically is a kind of alternating current generating means.This device changes into electric energy with the kinetic energy that produces in the process fluid flow.
2. background technology
When fluid (as air, water, etc.) when walking around the non-streamline object, that the object wake flow left and right sides can produce is paired, vortex that arrange, that direction of rotation is opposite alternately.This vortex is known as Karman vortex street.Fig. 1 is that Karman vortex street forms schematic diagram.The structure of the vortex in the Karman vortex street can be explained with the principle of circular rector conservation.Promptly when a whirlpool when the boundary layer of bluff (or claim vortex generation body) comes off, the existence in the whirlpool that circular rector is opposite with it must be arranged.In reality, when flowing through building, electric wire, bridge pier, fluid all can produce Karman vortex street.At vortex generation body rear, vortex can be along coming flow path direction to move backward.Simultaneously because the existence of the circular rector of single vortex, this whirlpool can be subjected to one with the incoming flow vertical direction on active force, i.e. lift.Thereby in Karman vortex street, fluid can be subjected to the periodically active force of alternation on the direction vertical with coming flow path direction.Theoretical and experiment all shows, (can represent) that under certain condition the structure of the vortex in the Karman vortex street is stable with the Reynolds number of fluid, thereby the relation of vortex generation frequency and rate of flow of fluid is determined.Widely used Karman vortex street flowmeter is exactly around this principle to make.
If in magnetic field, settle a wire coil,, the magnetic flux that passes coil is changed by the relative motion in coil and magnetic field.According to the law of electromagnetic induction, the variation of magnetic flux can make and produce electric current in the coil.Power periodic, alternating direction in the Karman vortex street can induce a wire coil that is placed in the fixing magnetic field to produce vibration.If this periodic vibration has changed the magnetic flux that passes wire coil, then in coil, produced alternating current.Fig. 2 utilizes vortex to induce the schematic diagram that produces electric current.
Since the vibration of coil be by alternately occur in the Karman vortex street vortex induce generation, so this device is become " vortex is induced generator ".The prerequisite of utilizing this device to produce alternating current is that flowing of fluid must be arranged, thereby this device also can be regarded as a kind of of wind energy generating plant.
3. summary of the invention
This invention utilizes the above-mentioned background technology, designs a device, and the kinetic energy that it produces when fluid is flowed changes into electric energy.
In this device, a vortex generation body is arranged, its cross section is trapezoidal.Vortex generation body is fixed in the housing.This housing in a tubular form, two ends are respectively the arrival end and the port of export of fluid.A rectangular metal coil is installed in the housing by rotation axis.The N utmost point and the S utmost point of two block permanent magnets are installed in the housing respectively, and in the both sides of wire coil.Fig. 3 and Fig. 4 are respectively that vortex is induced generator front elevational schematic and schematic top plan view.The Karman vortex street that fluid produces when flowing through vortex generation body causes the vibration in flow field, thereby drives the wire coil swing, so the magnetic flux in the wire coil can become cyclic variation, so produced alternating current in the wire coil.
This apparatus structure is simple, volume is little, and is in light weight, can be regarded as the unit of a generating set.During use, allow a plurality of such generators work together, to produce enough electric energy.

5. embodiment
The present invention will be further described below in conjunction with Figure of description and examples of implementation.
Examples of implementation: the operating state of this device after assembling as shown in Figure 3 and Figure 4.The vortex generation body that is the trapezoid cross section places the housing center.One side of trapezoidal base length of side broad is towards the fluid intake end of housing, i.e. left side one end among Fig. 3 and Fig. 4.The total length of housing should be not less than the trapezoidal base length of side of ten times vortex generation body.Its effect is the guide functions that the fluid that enters housing is played, and allows the vortex street of vortex generation body back that a development space is arranged.Rotating wire coil is installed in five times of trapezoidal bases, vortex generation body downstream length of side at a distance.Two block permanent magnets housing inner chamber, wire coil both sides.
This device is placed the incoming flow of certain orientation, for example in the wind field, perhaps this device is moved with certain speed, then fluid can enter housing by the arrival end of housing.Fluid is walked around vortex generation body, can produce Karman vortex street at its rear portion.Vortex in the Karman vortex street in pairs, reverse flow is through wire coil, and the wire coil moving axis that rotates produces vibration.Under the dead-beat situation, pass the magnetic flux of wire coil and fix.When wire coil vibrated, magnetic flux generating period variation thereupon was so produced alternating current in the wire coil.Two terminals of wire coil are drawn by the aperture on the housing.
