Description
Technical field
The present invention relates to a kind of electric energy storage device, relate in particular to a kind of accumulated energy flywheel.
Background technology
Accumulated energy flywheel is considered to best electric energy storage device, has that volume is little, in light weight, the efficient advantages of higher.Just more and more be applied to the every field that to carry out electric energy storage.
As shown in Figure 1, accumulated energy flywheel The main mechanical part structure comprises the flywheel 1 and the energy conversion device 2 of connecting shaft with it in the prior art, supports bearing 3 and other auxiliary mechanical structure of rotatable parts.
The accumulated energy flywheel complex structure of prior art uses inconvenience.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of simple in structure, the accumulated energy flywheel that reliability is high.
A kind of accumulated energy flywheel of the present invention, comprise: the permanent magnetic material flywheel of hollow, super-conductive magnetic suspension parts, stator and chassis, stator is hollow form and is fixed on around the chassis, the super-conductive magnetic suspension parts are fixed on the chassis, be positioned at the hollow form structure of stator, the permanent magnetic material flywheel of hollow is arranged in the hollow structure of stator.
A kind of accumulated energy flywheel, described chassis is rounded, and it is ring-like that described stator is hollow, and the permanent magnetic material flywheel of described hollow is rounded.
The invention has the advantages that: compared with prior art, accumulated energy flywheel of the present invention is simple in structure, and function is concentrated, good reliability.
Description of drawings
Fig. 1 is the accumulated energy flywheel structural representation of prior art.
Fig. 2 is an accumulated energy flywheel of the present invention vertical section schematic diagram.
Fig. 3 is an accumulated energy flywheel birds-eye perspective of the present invention.
Embodiment
Relevant technology contents of the present invention and detailed description, existing conjunction with figs. is described as follows:
Shown in Fig. 2,3, the invention provides a kind of accumulated energy flywheel, comprise: the permanent magnetic material flywheel 1 of hollow, super-conductive magnetic suspension parts 2, stator 3 and chassis.Stator 3 is the hollow circular ring type and is fixed on around the chassis.The chassis is rounded, and super-conductive magnetic suspension parts 2 are fixed on the chassis uniformly, and is positioned at the hollow circular ring type structure of stator 3.The permanent magnetic material flywheel 1 of hollow is rounded, is arranged in the circular ring type structure of stator 3.
A key character of superconducting phenomenon is a Meisser effect, be the diamagnetism of superconductor, its main idea is: when superconductor was in superconducting state, the magnetic line of force of external magnetic field can be excreted by superconductor, make that inner magnetic field intensity is zero, this phenomenon is called as Meisser effect.
The reason that this phenomenon produces is the supercurrent that formation can loss under the effect of superconductor outside magnetic field, induced field and external magnetic field opposite sign but equal magnitude that this supercurrent forms, after the external magnetic field interaction, make superconductor obtain suspending power, this correlation can prevent superconductor to move in discontinuous magnetic field in inner " pinning " phenomenon that produces of superconductor simultaneously, utilizes this characteristic to realize a kind of dynamic " location ".
Utilize said structure and principle, the present invention is in actual moving process, suspending power that produces after high-temperature superconducting magnetic levitation parts 2 enter superconducting state and guiding force can make permanent magnetic material flywheel 1 suspend, by providing energy to make 1 rotation of permanent magnetic material flywheel to stator 3 and storing this mechanical energy by motor; When needs release energy, make stator 3 and permanent magnetic material flywheel 1 convert mechanical energy to electric energy jointly by control unit and discharge, make accumulated energy flywheel can finish the process of energy storage and power conversion like this.According to the weight of permanent magnetic material flywheel 1, can suitably increase the quantity of super-conductive magnetic suspension parts 2, to guarantee reliable suspension.
The position of stator and rotor is not limited to rotor in stator.
Above-mentioned is preferred embodiment of the present invention only, is not to be used for limiting the scope of the present invention.Be that all equalizations of being done according to the present patent application claim change and modification, be all claim of the present invention and contain.
