Description
Technical field
The utility model relates to a kind of wind-driven generator, particularly a kind of underground railway tunnel wind power generator.
Background technique
Along with the raising of industrialization degree, the world today is increasing for the demand of the energy, and is increasing to the yield and the consumption of traditional energies such as coal, oil, rock gas.The total amount of these non-renewable resources is certain, adopts a just few portion, a day of always having exploitation to finish, and people press for now with the new energy and replace these traditional resources.Wind resource is to use many new energy recently, use many a kind of modes just to be to use wind-driven generator that wind energy is converted into electric energy to wind resource, relatively more commonly used is in the outdoor blower fan exploitation wind energy of setting up, but this kind mode is subjected to the influence of geographical environment bigger, and wind collecting do not have rule, and collecting energy is put aside and could be used within a certain period of time.
In recent years, the city rail construction of China development very fast, just opened ten with regard to one ground, Shanghai surplus a subway.We find when waiting train on platform, and subway can produce huge wind energy when entering the station and during departures, and subway per tour train number all is regular, and certain interval of time just has train to enter the station, and the wind energy of Chan Shenging also is to be periodic so.Simultaneously, for passenger's safety, and the loss of reduction waiting room air-conditioning, shielded gate all has been installed between track and Waiting Lounge, can we just expect utilizing the periodicity wind energy that is enclosed in the subway orbit to make it to be converted into electric energy like this.
Chinese invention patent Shen Qing Publication specification CN101334955A has announced a kind of wind energy type cartoon display screen, this display screen is installed in the orbit of subway, small-sized wind power generator is equipped with in upper edge and lower edge at display screen, wind-driven generator is respectively with storage battery, display device does not show during no wind-force, large wind rises when blowing, and wind power switch starts automatically, and display device shows.This model utility is the periodicity wind energy in utilizing track, and it is converted into electric energy uses, but this model utility is not used the periodicity wind energy transformation in the subway for the electric energy that can use continuously, simultaneously the utility model only under large wind blower fan just start working, utilization ratio of wind energy is low.
The model utility content
It is the wind-driven generator that electric energy uses and wind energy utilization is high of sustainable use that the technical problems to be solved in the utility model provides a kind of periodicity wind energy transformation that in subway tunnel train operation is produced.

Described unidirectional accumulation of energy buffering synchronizer comprises receiving terminal, discharges end and clockwork spring between the two, and described clockwork spring is connected with discharging to hold with described receiving terminal respectively; Described receiving terminal is connected with described one-way element, and described release end is connected with described multistage generator.
Described multistage generator is connected with external load or storage battery.
The fan radius of described wind wheel is 60 centimetres.
A pair of wind wheel is installed on both sides at subway tunnel at least.
Three pairs of wind wheels are installed on both sides at subway tunnel.
Described wind wheel is installed in the tunnel wall, and half embeds wall described wind wheel, and half is arranged on the wall outside.
Described wind wheel is made up of the big wind wheel of coaxial rotation, little wind wheel and the spider gear between two wind wheels.When diameter was identical, the blower fan that the number of blade is many rotated earlier, based on this, puts big blade outside the inner ring small leaf, and inside is equipped with the small gear of gearwheel and generator, forms high gear ratio.Like this, when low wind speed, big blade is relative to rotating earlier, and drive inner ring small leaf overcomes the resistance peak value, when inner ring rotating speed during greater than the outer ring, need not drive the outer ring blade.The wind-force that produces in the process of subway process also can drive the wind wheel rotation in smaller scope like this, thereby drives generator set work, and working efficiency is higher, and wind energy utilization is higher.
Described unidirectional accumulation of energy buffering synchronizer comprises receiving terminal, discharges end and clockwork spring between the two, and described clockwork spring is connected with discharging to hold with described receiving terminal respectively; Described receiving terminal is connected with described one-way element.At the collected energy of receiving terminal may be discontinuous, not at the uniform velocity.Put aside enough when big when the energy on the clockwork spring, clockwork spring will be in tight state, discharge end and can emit energy equably.At this moment, as long as receiving terminal still has energy before clockwork spring fluffs, discharge end and emit energy just continuously constantly.If a certain moment blade stops operating, the power that stores on the clockwork spring still can guarantee to discharge the uniform rotation of end, reaches the evenly effect of output of electric energy.When blade restarts to rotate, clockwork spring will begin the accumulation of energy in another cycle.Theoretically, if cycle of once releasing energy fully of clockwork spring, just can accomplish that the breakpoint of energy in the whole process of moving renews greater than the interval of adjacent twice subway process.So the utility model underground railway tunnel wind power generator is the periodicity wind energy transformation that train operation produces the electric energy of sustainable use in subway tunnel.
