Description

A kind of pneumatic type energy-storing and power-generating system

Technical field

The utility model relates to the electromechanical equipment technical field, especially relates to a kind of pneumatic type energy-storing and power-generating system.

Background technology

At present, adopt the mode of compressed-air energy storage actually rare, usually adopt electrochemical means storage of electrical energy such as lead acid storage battery equipment, yet the defective that this mode exists is that the charging interval is oversize, the oversize use that limits energy storage device of charging interval, seek new energy storage mode and be always one of focus that the technical staff studies, adopt air pump compressed air form energy storing and electricity generating to be expected to provide a kind of new new application model of energy storage, generating, electricity consumption.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of pneumatic type energy-storing and power-generating system, and this electricity generation system adopts novel energy-storing device, can be fast with electric energy conversion storage, and fast the energy of compressed-air actuated storage is reduced to electric energy.

For achieving the above object, the utility model by the following technical solutions:

This pneumatic type energy-storing and power-generating system comprises air pump, air motor, generator, air pump drives air motor, the power shaft of the output shaft connecting generator of air motor, the electric energy output end of generator is connected with the input port of a switching device, and the output port of this switching device connects the input of air pump supply unit.

The beneficial effects of the utility model are:

Compared with prior art, the utility model adopts different energy storage and power generation mode fully, be that electric energy conversion storage or energy reduction conversion are all quite rapid, the utility model is stored with compressed-air actuated form electric energy with the quick-frozen conversion that is exceedingly fast, can be carried into the place that needs electric energy and can't directly power after the storage, then the rapid release of compressed-air actuated energy being converted to electric energy is externally fed, and a part of power cycles is used, and is a kind of novel energy storage, generating equipment.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, take a hint to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.

Description of drawings

Accompanying drawing is the principle of compositionality figure of system of the present utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in the figure, the pneumatic type energy-storing and power-generating system of present embodiment comprises air pump, air motor 2, generator 1, air pump comprises the electronic pump housing 5 that compressed air is used and the cavity 4 that is used for the store compressed air, during concrete the use, can adopt the whirlpool air pump, the operation principle of vortex air pump is: be made up of tens of blades on the impeller, its similar huge gas turbine impeller, when the impeller of vortex air pump rotates, air in the middle of the impeller blade is subjected to action of centrifugal force, border movement towards impeller, air enters the toroidal cavity of the pump housing there, return impeller then again, carry out shuttling movement in the same way again from the starting point of blade again, because air is quickened uniformly, the circulating current that is produced during the impeller rotation makes air scurry out with the form of helix, so air leaves the pump housing with high energy, for use, the characteristics of air pump are the storage of energy and discharge rapidly; The device translates time of this and common electrochemical means storage of electrical energy is much smaller, and it is quite high therefore to have the research using value.Air motor is to be prime mover of working media with compressed air, and it is the expansion of adopting Compressed Gas, can be converted to the power set of mechanical energy to pressure, is the direct tool that compressed air energy discharges conversion.In the utility model, the cavity that is used for the store compressed air 4 of air pump is connected with air motor 2 by high-pressure air pipe 3, the power shaft of the output shaft connecting generator 1 of air motor 2, the electric energy output end of generator 1 is connected with the input port of a switching device 6, the output port of this switching device 6 connects the input of air pump supply unit, the electric energy output end of generator 1 also is connected with power consumption equipment such as lighting bulb 7, like this, the utility model just can adopt compressed-air energy storage, and release compressed air pushing generator 1 generating, the part of the electric energy that generator produces can be powered for power consumption equipment, another part can circulate by switching device 6 and be the use of air pump compressed air, in order to avoid cause waste of energy, realize the energy circulation utilization and save utilization, air pump can use external power supply 8 to carry out air compression by switching device 6 in advance when specifically implementing.Compared with prior art, system of the present utility model can be carried to the device of the utility model system Anywhere then fast with electric energy conversion storage, discharges the energy of storage, still utilizes the energy with the form of electric energy.The utility model provides a kind of electric energy has been changed storage fast, and the technical scheme of fast restore use, has higher application prospect.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
