Description
(1) technical field:
The utility model relates to a kind of improvement technology of flying wheel battery, particularly a kind of dynamical double-flywheel battery.
(2) background technology:
At present, the storage battery kind that people use in productive life is a lot, as lead-acid battery, lithium battery, fuel cell, superconducting energy storage battery etc., wherein using at most, the widest energy-storage battery is undoubtedly chemical cell, it changes electric energy into chemical energy and stores, be converted into electric energy output again, and the shortcoming of the same its existence of other storage batterys: the one, energy storage density is little, and the electricity consumption time is short; The 2nd, discharge and recharge number of times and be restricted, so useful life is short; The 3rd, the charging interval is long, and service efficiency is low; The 4th, caused second environmental pollution, battery needs to be recovered processing after using.
Progress and development of science and technology along with society; people are more and more higher to the requirement of environmental protection and battery performance; though the accumulation of energy mode of fuel cell, superconducting energy storage battery is advanced more; can meet people's requirement; but fuel cell need constantly be safeguarded; its range of application is little, and the operational environment of superconduction energy storage battery has strict restriction, and old friends are developed the flying wheel battery that mechanically energy storage gradually.Flying wheel battery is the new ideas battery that the world just proposes the nineties, it has broken through the limitation of chemical cell, realize a kind of technology of energy storage with physical method, existing flying wheel battery mainly is by a flywheel body, the motor that can drag the flywheel body rotation is that motor generator and Technics of Power Electronic Conversion device constitute, motor drives flywheel operation when its operation principle is charging, flywheel store kinetic energy (mechanical energy), flywheel drives generator operation during discharge, kinetic energy is converted to electric energy, the shortcoming of its existence is that moment loading is in the axle center, starting torque is big, makes the rotating speed of flywheel be restricted, thereby has influenced the power and the energy storage effect of battery.
(3) summary of the invention:
The purpose of this utility model is that a kind of double-flywheel battery will be provided, it not only can increase the energy storage of flywheel, and can improve the limit speed of flywheel, thereby have that stored energy capacitance is big, effect is good, charging is fast, energy consumption is low, effect is high, a long service life, free of contamination remarkable advantage.
The utility model is to constitute like this, it comprises the sealing outer cage of being located on the support, rotating shaft, bearing, the main rotor that links to each other with rotating shaft, be located at outer cage inner surface and the corresponding main motor stator of main rotor, vacuum nozzle and Technics of Power Electronic Conversion device, it is characterized in that: described rotating shaft both sides respectively are equiped with a flywheel assembly, the bracing frame that described each flywheel assembly is installed flywheel body by a pair of flywheel body and being used to constitutes, described bracing frame is fixedlyed connected with rotating shaft, at the outer of described flywheel body circumference or interior along being equiped with magnetic pole on the circumference, constitute the flywheel-type rotor with this, on the inner surface of outer cage, be provided with and the corresponding flywheel-type motor stator of flywheel-type rotor.
The utility model is when charging, the Technics of Power Electronic Conversion device is connected external power supply and is given main motor power supply, this moment, main motor used as motor, quicken for the flywheel of rotating shaft both sides, promptly utilize the inertia force store kinetic energy of flywheel high speed rotating, finish the conversion of electric energy to kinetic energy (mechanical energy), when discharge, flywheel applies torque for main motor, drive main motor rotation, this moment, main motor used as generator, externally exported electric energy by the Technics of Power Electronic Conversion device, finished the conversion of kinetic energy (mechanical energy) to electric energy.
Because the flywheel design of rotating shaft both sides becomes the flywheel-type rotor, and on outer cage, be provided with the flywheel-type motor stator, so it constitutes the flywheel-type motor, it can cooperate acting to alleviate main electric motor starting load with main motor simultaneously, make it shorten the starting time, increase work efficiency, thereby reach the effect that the double-flywheel battery fast energy storage charges.Again because interior in flywheel body along being equiped with magnetic pole on circumference or the outer circumference, the moment loading of flywheel is on circumference when rotated, so can improve the limit speed (per minute can reach ten thousand change more than) of flywheel, thereby has the effect height, energy consumption is low, the energy storage effect is good, the remarkable advantage of long service life.
The utility model is owing to adopt the structure of round trip flight wheel, so can increase the energy storage of flywheel, stored energy capacitance is big, effect is good, the fast advantage of charging thereby have.In addition, the utility model also has advantage simple in structure, in light weight, easy to use, pollution-free, repeatedly used, and it is specially adapted to the effectively power source of electric automobile, and is used for energy storage devices such as transformer station, hydroelectric station and civilian traffic instrument.
