Description

Wave energy and vibrational energy generator

Technical field

The utility model relates to a kind of generator.Especially the vibrational energy in living and the wave energy in ocean more effectively change into the generator of electric energy.

Background technology

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

Generator is other forms of energy conversion to be become the plant equipment of electric energy.At present main flow is that rotary generator consists 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, by binding post, draw, be connected in 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 at coil, produces induced potential, 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, for the Wave energy in discrete vibrational energy periodically and ocean in life, changes into electric energy, is not very desirable and effective Conversion of Energy mode.

Summary of the invention

The utility model discloses a kind of new-generation mechanism body simple in structure, run up and make wire carry out cutting magnetic line with need not generating electricity parts, but by forming two magnetic circuit component of generator, do relatively reciprocating motion to change magnetic resistance or the magnetic potential of magnetic circuit in vibration or fluctuating wave environment, and then the magnetic flux intensity in the change coil, a kind of electricity-generating method of generation current in generator coil, the structure of generator is more suitable for transforming in wave energy and vibrational energy ground, can improve wave energy and vibrational energy ground power benefit.

The generating structure 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.

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, 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 is consistent, at this moment the huge increase of magnetic resistance makes the magnetic flux in magnetic circuit occur to change hugely, and the coil on iron core just has huge current flow ground to produce.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.

To be divided into the magnetic circuit of two sections, and be called moving magnetic circuit and magnetostatic road, will move magnetic circuit and be called mover, magnetostatic road is called stator, and mover and stator form the generating movement jointly.Stator and casing directly are fixed together.Mover is connected with elastomeric material with casing, can do and do relatively reciprocating motion with casing and stator under external force and self inertia power and elastomeric material effect.

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 and is in the same place with stator by magnetic force.

In order to make mover when stator moves upward with housing, by magnetic attraction, with stator, do not moved in the same way, at this moment can on mover again with addition of other gravity, to connecting container on mover, the cheap practical mass such as splendid attire metal derby and stone, 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, mover and stator are just 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.

Stator also can be fixed on casing by connecting rod or connecting plate, with casing, is synchronized with the movement;

Mover is fixed on connecting plate, and the connecting rod two ends are separately fixed at container and fixedly on the connecting plate of mover, container and mover are connected and fixed;

The mover two ends also can directly be fixed on connecting plate and container;

The elastomeric material two ends are connected to the connecting plate that is fixed with mover and are fixed with on stator connecting plate or casing, mover and casing or stator connecting plate are linked together, mover is under the effect of external force or self inertia power and elastomeric material, with stator generation reciprocating motion.

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.
