Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Please refer to Fig. 1-Fig. 6, the present invention provides a kind of some embodiments of hydromagnetic generating device.
As shown in Figure 1 and Figure 4, a kind of hydromagnetic generating device of the invention, comprising: magnetic fluid, magnet 10, pedestal 20,
First electrode 30 and second electrode 40 on the pedestal 20 are set;Fluted 211, described first is arranged on the pedestal 20
The opening that electrode 30 seals the groove 211 forms the cavity for accommodating the magnetic fluid;The second electrode 40 and the magnet
10 are sequentially located on the opening direction of the groove 211, have gap between the second electrode 40 and the first electrode 30.
It is worth noting that hydromagnetic generating device is controlled using following steps:
Change the distance between magnet 10 and magnetic fluid, so that magnetic fluid magnetizes, and pushes first electrode 30 and second electrode 40
Collision and friction.
It can change the distance between magnet 10 and magnetic fluid by the movement of magnet 10, the movement of magnet 10 here can be with
Using periodical move mode, for example, being moved back and forth back and forth using the opening direction along groove 211, when magnet 10 and magnetic current
The distance of body farther out when, magnetic fluid is not magnetized, then will not to first electrode 30 generate active force, first electrode 30 and second
There are gaps between electrode 40, will not collide and rub, and would not also produce electricl energy;When magnet 10 is at a distance from magnetic fluid
When closer, magnetic fluid is magnetized, then active force can be generated to first electrode 30, and gradually deformation, the first electricity occur for first electrode 30
Gap between pole 30 and second electrode 40 gradually becomes smaller, and collides and rub, to produce electricl energy.
When the minimum range of magnet 10 and magnetic fluid is in 1-20mm, it can be ensured that the magnetic attraction of magnet 10 is effective, also
It is to say, when magnet 10 is within the scope of magnetic fluid to 1-20mm, power generation can be realized.The court after magnet 10 reaches minimum range
Direction far from magnetic fluid is mobile, and magnetic fluid can be demagnetized, reaction force attenuation and disappearance of the magnetic fluid to first electrode 30, and first
Electrode 30 restores deformation, and the gap between first electrode 30 and second electrode 40 is restored.By controlling the magnetization of magnetic fluid and moving back
Magnetization, can make constantly to collide and rub between first electrode 30 and second electrode 40, and produce electricl energy.
Certainly, magnet 10 can also be mobile using other modes, for example, translating in the horizontal direction, as long as can change
Spacing between magnet 10 and magnetic fluid so that magnetic fluid magnetization and it is demagnetized.Magnet 10 uses permanent magnet 10.

It is generated electricity using magnetic fluid and the cooperation of magnet 10, is conducive to that miniature power generating device, the magnetism in magnetic fluid is made
Particle is usually nano particle, even if miniature power generating device is made, magnetic fluid still be can work normally, and the voltage exported is steady
It is fixed.In the prior art, for example, using the pedal force of people's (foot) as drive force first electrode 30 with second electrode 40 collision and
Friction, people's (foot) directly contact with first electrode 30, in this contact power generation, since the movement of each one (foot) is irregular
, pedal force is not also identical, and people's's (foot) tramples that motion profile is consistent with the motion profile of second electrode 40, this results in first
Collision and friction between electrode 30 and second electrode 40 is unstable, and output voltage is also just unstable.In the present invention, magnet 10 with
Second electrode 40(or magnetic fluid) do not contact, this contactless way of propelling dramatically reduces manual operation
Microscopic instability caused by error further improves voltage output stability.

Powder is dispersed in base load liquid, and in the influence in not magnetic field, nano ferriferrous oxide granule carries out unordered fortune in base load liquid
It is dynamic, it is similar to Brownian movement.Due to the influence in the magnetic field of magnet 10, nano ferriferrous oxide granule is magnetized, then then carrying out
Regular movement, formed direction on the whole be directed towards magnet 10 (certainly here with regard to single nano ferriferrous oxide
It for particle, although being influenced by magnetic attraction, is not necessarily towards the movement of magnet 10).Therefore, magnetic fluid is to first electrode
The size of 30 active force can be controlled by the minimum range between magnet 10 and magnetic fluid.
The volume ratio of nano ferriferrous oxide and base load liquid is higher, and output voltage is higher, nano ferriferrous oxide and base load
The volume ratio of liquid is 20%-50%.
