Abstract

The invention relates to a wind driven generator with multiple wind wheels, comprising a machine frame, an electric generator, a support bar, wind wheels, a wind rudder, a plane bearing which enables the wind wheels to rotate in all directions; the minimum number of the wind wheels is 2. Two installation methods of the wind wheels are available. In the first method, a plurality of wind wheels are arranged on the machine frame by the support bar, each wind wheel drives the electric generator to work by driving a driving shaft which is arranged in the support bar. In the second method, a plurality of wind wheels are arranged on the machine frame by a plurality of support bars, each wind wheel drives the electric generator to work by driving a driving shaft which is arranged in the support bar. A plurality of wind wheels are arranged on the machine frame by one or a plurality of support bars, the wind wheels drive the electric generator, thus reducing diameter of the wind wheels and height of the machine frame; in addition, the wind wheels act in coordination, thus increasing wind area and improving power generation efficiency.

Description

Wind driven generator with multiple wind wheels
Technical field
The present invention relates to a kind of wind-driven generator, particularly a kind of synchronous windy wind-driven power generator of taking turns that makes full use of wind energy.
Background technique
Wind is the very big new energy of a kind of potentiality, and wind has just sent the power of 10,000,000 horsepowers (promptly 7,500,000 kilowatts) in the several seconds.According to estimates, the wind resource that can be used to generate electricity on the earth has 10,000,000,000 kilowatts approximately, almost is 10 times of present whole world hydroelectric power amount.Though wind is utilized by people very early--mainly be by windmill draw water, flour milling etc., just begin to utilize the trial of wind-power electricity generation up to the beginning of this century.
The '30s, Denmark, Sweden, the Soviet Union and the U.S. use the rotor technology of aviation industry, have successfully developed some small wind-driven generators.This small-sized wind power generator extensively uses on windy island and remote rural area, and the power cost that it obtained is more much lower than the cost of electricity-generating of compact internal combustion engine.But, generated energy at that time is lower, mostly below 5 kilowatts.Modern society has stepped into the period of the quick development and utilization energy.The energy continues basis progressive and development as entire society, and its status is more and more paid attention to by people.But as the coal and the oil of traditional energy, because the complicated mechanism of its formation can not recycle for people as the reproducible energy.And in the last hundred years, people's exploitation and use scale are increasing, and coal and petroleum resources have shown and have been about to depleted sign, so, the pressing issues that energy crisis has just become contemporary society to solve.Atomic power is as a kind of new energy, but utilizing, it needs extremely complicated and most advanced and sophisticated technical know-how, and the processing of development and maintenance cost and nuclear waste is perplexed always and is being limited its promotion and application, and its Security also is a key factor must considering, pollution and the injury that is caused leaked in Soviet Union Chernobyl Plant blast then, still is difficult to even to this day eliminate.And wind energy is vouchsafed the eco-friendly power source of our tool prospect as nature, not only widely distributed, and we can say inexhaustible, without cease with it, when we utilize wind energy power, not only can provide huge never depleted electric energy to us, and can reduce near the wind-force in the face of land, and alleviate sand and airborne dust, improve the cleaning of surrounding environment.Therefore, all take much count of both at home and abroad utilizing wind-force to generate electricity, tap a new source of energy.
Utilizing wind energy power generally all is to adopt to fix a rod assemblies on the ground, in the rod assemblies upper end cantilever is installed, the cantilever two ends are provided with wind wheel and generator respectively, the moving wind wheel rotation of wind, the kinetic energy of keeping watch is transformed into mechanical energy, wind wheel produces electric current by the rotor rotation and the cutting stator magnetic field of output axle driven dynamo, again mechanical energy is converted into electric energy, Here it is wind-power electricity generation.Therefore, wind wheel is the vitals that the kinetic energy of keeping watch changes mechanical energy into, and it is made up of the impeller of two to three double helix oar shapes.When wind during, produce aerodynamic force on the blade and drive wind wheel and rotate to paddle.
In order to improve the wind-power electricity generation acc power, existing wind-driven generator is to increase rotor diameter and support height mostly, enlarges the place and increases the platform number.The diameter of wind wheel maximum has been increased to 50-100M at present, and great majority are installed in away from the grassland in city or desert region, and floor space is big, and making, installation, maintenance all have certain degree of difficulty.
Though this increase wind wheel, increase support and certain effect arranged to improving the wind-power electricity generation acc power, but because present wind power plant generally all is in the cover power generating equipment, a wind wheel only is set, such structure cause only utilized wind wheel the wind energy of an aspect aloft.And the distribution of wind energy is very extensive in vertical direction, and how the wind energy of utilizing different aspects as much as possible has very important significance for improving generated energy and making full use of wind energy resources.
Summary of the invention
At the deficiencies in the prior art part, the objective of the invention is to overcome the shortcoming of prior art, the wind driven generator with multiple wind wheels that provide that a kind of volume is little, power is big, can make full use of the wind energy of different aspects.
In order to realize purpose of the present invention, the technical solution used in the present invention is: wind driven generator with multiple wind wheels, and comprise frame, generator, strut, wind wheel, wind rudder, make the plane bearing that wind wheel can universal rotation, described wind wheel is at least two.
The mounting type of described wind wheel can have two kinds: a kind of mode is, by a strut a plurality of wind wheels is installed on frame, and each wind wheel is by the drive shaft generator for electricity generation of drive installation in strut.
Another kind of form is, by a plurality of struts a plurality of wind wheels is installed on frame, and each wind wheel is by the drive shaft generator for electricity generation of drive installation in strut.
Beneficial effect of the present invention is: by one or more struts, a plurality of wind wheels can be installed on frame, a plurality of wind wheels drive a generator, reduce rotor diameter, thereby reduced the height of dynamo cradle, windyly taken turns acting in conjunction, increase blowing area, improved generating efficiency.The wind energy purpose that realized that volume of the present invention is little, power is big, can make full use of different aspects.
