Description

Wave energy and vibrational energy generator

Technical field

The present invention relates to the electromagnetism field.The objective of the invention is more effectively to change into electric energy for vibrational energy and the Wave energy in the ocean in life, propose a kind of principle and method of new exploitation.

Background technology

The wave-energy power generation mode is a lot, and traditional generator changes into electric energy with wave energy but all must use now.

Generator is other forms of energy conversion to be become the plant equipment of electric energy.At present main flow is that rotary generator is made of parts such as stator, rotor, end cap and bearings usually.During generating, require rotor in the rotation of stator high speed, do the motion of cutting magnetic line, thereby produce induced potential, draw by binding post, be connected in the loop, just produced electric current.

Be exactly linear electric motors in addition, linear electric motors are exactly that a dynamotor that rotatablely moves is cut open along the direction of radius, and flatten, and this has just become a linear generating motivation.In linear electric generator, be equivalent to the rotary electrification machine stator, cry elementaryly; Be equivalent to the rotary electrification machine rotor, cry secondaryly.The permanent-magnet reciprocating linear electric generator provides magnetic field with permanent magnet, and is the same with the permanent magnet generator of rotation, and the permanent magnet of linear electric generator is also to be contained on movement parts, and coil is in the stator core of silicon steel material.Its principle is also the guidewire movement cutting magnetic line, thereby produces induced potential at coil, at the coil middle generation current of returning.

above these two kinds of electricity-generating methods, to dominate now GENERATION MARKET tradition main flow electricity-generating method, the restriction of generator operation conditional request is more, change into electric energy for the Wave energy in discrete vibrational energy periodically and ocean in life, it not very desirable and effective Conversion of Energy mode, the present invention proposes a kind of simple in structure, the generator operation condition restriction is few, be not coil run up cutting magnetic line, but change magnetic resistance or the magnetic potential of magnetic circuit by the aggregate motion of mechanism, and then the magnetic flux intensity in the change coil, a kind of electricity-generating method of generation current in coil.

The seagoing vessel of tens tons, up to a hundred tons that navigates by water in the sea, under the effect of wave, just as a leaf floating in nautical mile following sea, but to allow on land its fluctuating be need to be very large energy.Of the present invention is exactly to allow such energy change into electric energy, serves navigation, makes the wave energy can be as one of additional power of navigation, thereby reduces the consumption of gasoline.

Summary of the invention

The present invention discloses a kind of across the sea floating, and all generating parts directly do not contact with seawater, and once wave power generation or vibrational energy is converted to the method for electric energy.

The electrification structure that wave energy or vibrational energy is once changed into electric energy is such: form closed magnetic circuit by coil, iron core and permanent magnet and be placed in casing, the generating casing with floating body in Motion Waves.

The generation mode that this patent is set forth, its principle part profile is just as transformer, different from transformer is, in the magnetic conductive material of closure, the existence of permanent magnet is arranged, permanent magnet and magnetic conductive material iron core (as silicon steel sheet) formed magnetic circuit, and magnetic circuit be divided into can closure and two parts of split movement, and other have formed generating body as all parts such as elastomeric material, casings.

At first magnetic circuit is divided into two sections, when being divided into magnetic force between the magnetic circuit parting surface of two sections and being magnetic attraction, in two sections processes of separating of magnetic circuit, magnetic circuit Air gap increases, the magnetic resistance of air is far longer than the magnetic resistance of iron core, when permanent magnet performance was consistent, the at this moment huge increase of magnetic resistance made the magnetic flux in magnetic circuit occur to change hugely, and the coil on iron core just has huge current flow ground generation.Two sections of magnetic circuits are approached in closed ground process, the magnetic resistance in magnetic circuit reduces again, and in iron-core coil, magnetic flux increases, and on iron core, coil equally also has electric current to produce.

The magnetic circuit of two sections be will be divided into, moving magnetic circuit and magnetostatic road will be called.Magnetostatic body and casing directly are fixed together.Moving magnet is connected with spring with casing, can do relative motion with casing in the time of under external force.To move magnetic circuit and be called mover, magnetostatic road is called stator, and mover and stator form the generating movement jointly.

Form mover and the stator of magnetic circuit, be the generating movement.It can have coil, iron core and permanent magnet simultaneously; Also can have respectively the part in coil, iron core or permanent magnet.But whole magnetic circuit must have coil, iron core and permanent magnet three parts.。

The generating body that stator, mover and casing are formed is positioned on floating body in the environment of ocean wave or in the environment of vibration, due to the effect of extraneous power, stator and casing move in the same way.The gravity of mover itself less than and the stator contact-making surface between magnetic attraction the time, act directly on mover without other external force again except magnetic attraction, mover is inhaled with stator by magnetic force and is in the same place.

In order to make mover when stator moves upward with housing, do not moved in the same way with stator by magnetic attraction, at this moment can on mover again with addition of other gravity, make effect power thereon can and stator two contact-making surfaces between magnetic attraction form balance, as long as external force is arranged like this, just mover and stator are separable, both do relative reciprocating motion, just generation current in coil, generating body just changes into electric energy with the wave energy in vibrational energy or ocean Dispensable continuously like this.

Secondly, when magnetic circuit is divided into two sections, if when the magnetic force of two sections magnetic circuit parting surfaces is repulsion, at this moment two sections magnetic circuits is that magnetic potential on the magnetic circuit iron core reduces near meeting, because magnetic potential ground reduces, occur in coil magnetic flux reduce change, in coil thereby the generation of electric current also just arranged.

In the process that two sections magnetic circuits separate, the magnetic potential on the magnetic circuit iron core occurs constantly to increase, and due to the increase of magnetic potential, the increase that magnetic flux occurs in coil changes, and coil also just has the generation of electric current simultaneously.Equally, by giving the mover counterweight, so that it produces best generating effect.

Embodiment

Fig. 1 is vibrating type electric generator core stereoscopic principal figure.

Magnetic force between two magnetic circuit parting surfaces is magnetic attraction.As Fig. 1 coil 1, iron core 2, permanent magnet 3 have formed the stator of generating movement.Coil 5, iron core 6, permanent magnet 7 have formed the mover of generating movement.In this figure, generating movement mover and stator all comprises coil, iron core, permanent magnet three parts, Fig. 1 for generating movement stator and mover two parting surfaces away from the time situation.The parting surface 4 of mover and stator constantly approach with away from the time, coil 5 changes with magnetic flux and magnetic flux density in coil 1, and the generation of electric current is arranged in two coils.

Fig. 2 is the structural upright schematic diagram of vibrating type electric generator

In Fig. 2, be that the generating movement with Fig. 1 is placed in casing, stator 9 use connecting rods 2 directly are fixed on the upper end of casing 1, move in the same way simultaneously with casing 1.Be fixed with connecting plate 7 on mover 4, be connected with spring 3, connecting rod 6 and positioning track 8 each two on connecting plate 7, spring 3 is that extension spring is connected with the upper end of casing 1, container 5 below connecting rod 6 connects, positioning track 8 and casing 1 upper end are directly fixing, and positioning track 8 is that restriction connecting plate 7 only can move up and down.Its effect is that restriction mover 4 only can move up and down with respect to stator 9.5 li objects that counterweight can be housed of container, as other mass such as metal derby or stones, the gravitation energy and the magnetic attraction between mover 4 and 9 liang of parting surfaces of stator that make all connections and act on mover 4 form equilibrant force, this point is one of most important factor, the size of mass gravity must and the magnetic attraction of 9 of mover 4 and stators form equilibrant force, at this moment, be zero making a concerted effort between mover and stator, chest is as long as upward next is moving, and mover will separate with stator.Mass gravity is excessive and too small, all will affect mover and separates with stator ground and approach closed.Again it, the selection of spring parameter is two of key factor, elastic force is excessive, mover can not separate with stator.Elastic force is too small, and mover and stator can not returns, all can cause mover and stator not to separate constantly and approach.

Be positioned over Fig. 2 whole generator in vibration environment or be positioned on a floating body, floating on the environment of ocean wave, whole generator can directly not contact with water, in the ocean of rising one after another, has electric current to produce in its coil and continues like this.

Fig. 3 is the another kind of manifestation mode of Fig. 2, be only will assembling kind of thing container 1 be placed on above casing 3, positioning sleeve 4 fixes with the casing upper end, restriction connecting rod 2 only can move up and down.Mover in connecting rod 2 connecting containers 1 and casing passes casing 3 upper ends and can move up and down with respect to casing, and power generation process is described consistent with Fig. 2.

Fig. 4 is that two magnetic circuit parting surface magnetic force are situations of repulsion, wherein container 1 is connected in aggregates with mover single piece 3 by connecting rod 2, connecting rod 2 passes casing 6 upper ends, and the positioning sleeve 7 of connecting rod 2 is together with the casing upper end is fastening, and restriction connecting rod 2 only can move up and down with respect to casing.

Stator single piece 5 is fixed on below casing, and is connected with stage clip 4 between the mover single piece.Container 1 is equipped with mass, when moving up and down in overall with respect to casing 6, mover single piece 3 and stator single piece 5 will the up and down away from approach motion, so just generation current in the coil of stator and mover!

The selection of stage clip 4 parameters is that the size of repulsion between the size of or vibration amplitude high according to wave wave and magnetic circuit decides, and adding of mass makes power benefit reach best.

Fig. 5 is the schematic diagram of another compound mode of vibrating type electric generator core mover and stator.

Iron core 3 in Fig. 5 on (A) figure is the stator 9 on (B) figure in Fig. 5 with permanent magnet 4 and coil 2, iron core 7 in Fig. 5 on (A) figure is another stator 11 on (B) figure in Fig. 5 with permanent magnet 6 and coil 8, (A) the non-core material in figure 1 is the mover 10 on (B) figure in Fig. 5 with iron core 5, two parts stator 9 and stator 11 are arranged like this, a mover 10 forms the generating movement.This attraction of the equal magnetic of magnetic force between two stators and between mover.

Iron core 6 in the mover of Fig. 5 (A) generating movement is nearest with stator, and at this moment the magnetic resistance in magnetic circuit is minimum.

Iron core 6 in the mover of Fig. 5 (B) generating movement and stator away from, at this moment the magnetic resistance in magnetic circuit is maximum.

This generating core is placed in the environment of vibration and ocean wave, figure in Fig. 5 (A) alternately occurs with the situation of figure (B), at this moment the variation of magnetic resistance is just arranged in coil, in coil, the variation of magnetic flux has just been arranged also simultaneously, just had electric current to produce constantly in coil.

Fig. 6 is placed on the structure of Fig. 5 vibrating type electric generator the three-dimensional combination figure of casing.

In Fig. 6, the container 1 of placing mass is fixed together with generator mover 2 and mover connecting plate 7, forms the mover single piece.
