Abstract
An offset vertical axis wind turbine structure comprises a vertical axis, a generator, a controller, a joint tray, swing axis devices, blades and the like. The offset vertical axis wind turbine can be started by gentle breeze, dispense with spoiler adjustment, is simple in structure design, convenient in maintenance and high in generating efficiency and can be randomly modeled to beautify the environment. Wind energy is combined to the grid. Wind is inexhaustible, thus wind is quite suitable for and has bright prospect in generating power in such places lacking water and fuel and being inconvenient in traffic as offshore islands, grassland pasturing areas, maintain areas and plateau areas, scenic spots, frontier defense areas, schools, troops and even the backward mountainous areas. Sea wind is used for generating power on the sea and the blade system can be placed in the sea, being not affected by the flow direction, the energy of the sea waves and tides can be used for generating power, and flow movement can be used for generating power in the rivers, thus the wind turbine widely popularizes the best clean energy.
Description
Technical field
The invention belongs to the energy field of cleaning, along with the rise of wind-power electricity generation, wind energy more and more is subjected to the attention of countries in the world as a kind of renewable energy sources of cleaning.The Chinese feature energy storage capacity is very big, distribution is wide, and development and use have a high potential.Wind generating technology is the technology that wind energy is changed into electric energy.Realize by wind-driven generator, utilize wind-force to drive the air vane rotation, impel generator for electricity generation.
Background technique
Along with the continuous development of science and technology, new energy field requires to have high efficiency, the wind-power electricity generation machinery efficient of using at present is low, complex structure, be not easy to safeguard, cost is high, as: horizontal axis wind motor, current vertical axis aerogenerator etc.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, efficient is high, the vertical axis aerogenerator of applied range, vertical axis aerogenerator need not in change of the wind wind, be a big advantage with respect to horizontal axis wind-driven generator in this, it not only makes structural design simplify, and the gyro power when having eliminated wind wheel to wind, the object of the present invention is achieved like this:
1, a kind of offset vertical axis wind turbine is characterized in that:
Offset vertical axis wind turbine blade system structure, to blade from the center to the edge, form with offset distance is installed on the sharf, under the effect of wind-force or fluid power, make blade produce gyro power, make wherein on one side blade rotation to the resistance minimum of substantially horizontal generation, the resistance maximum that the another side blade rotation produces to Vertical direction, under the effect of wind-force or fluid power main shaft is produced rotating force, directly drive equipment turns round, or drives the generator generating of turning round.
2, offset vertical axis wind turbine according to claim 1 is characterized in that:
The offset vertical axis wind turbine structure, form by vertical shaft (1), generator (2), controller (3), land (4), swing axle device (5), blade (6), on vertical vertical shaft, generator is installed, connect controller on the generator, land is installed again, one or more groups swing axle device is installed on the land, and blade is installed in parallel on the swing axis two ends with the form of offset distance, forms a work system.
3, offset vertical axis wind turbine according to claim 1 is characterized in that:
The offset vertical axis wind turbine structure, form by vertical shaft (1), generator (2), controller (3), land (4), sharf (9), blade (6), stop collar (10), on vertical vertical shaft, generator is installed, connect controller on the generator, land is installed again, connect two or many sharfs on the land, blade is installed in parallel on the sharf by stop collar with the form of offset distance, forms a work system.
4, offset vertical axis wind turbine according to claim 1 is characterized in that:
The offset vertical axis wind turbine structure, form by vertical shaft (1), generator (2), controller (3), connecting rod (7), supporting frame (8), sharf (9), blade (6), on vertical vertical shaft, generator is installed, connect controller on the generator, connecting rod is installed again, one or more groups supporting frame is installed on the connecting rod, two or many sharfs are installed on supporting frame, blade is vertically mounted on the sharf with the form of offset distance, forms a work system.
5, offset vertical axis wind turbine according to claim 1 is characterized in that:
The blade shape of offset vertical axis wind turbine can be square, also can adopt circle, rectangular, ellipse, irregular shape.
6, offset vertical axis wind turbine according to claim 1 is characterized in that:
