Description
Technical field
It is the wind energy conversion system of mechanical energy that the utility model relates in a kind of wind power generation field wind energy transformation, more particularly, relates to a kind of vertical axis wind energy conversion system.
Background technique
Wind is the very big new energy of a kind of potentiality, and the someone estimated that the wind resource that can be used to generate electricity on the earth had 10,000,000,000 kilowatts approximately, almost is 10 times of present whole world hydroelectric power amount.The present energy that obtained of the annual coal combustion in the whole world, have only wind-force in 1 year the energy that provides 1/3rd.Therefore, all take much count of both at home and abroad utilizing wind-force to generate electricity, tap a new source of energy.Utilize the trial of wind-power electricity generation, just begun as far back as 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 is widely used in 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.
At present, what the wind energy conversion system of wind-power electricity generation adopted is horizontal axis, and promptly the rotatingshaft of wind energy conversion system is to be horizontally disposed with.Working state when adapting to different wind direction, wind energy conversion system is provided with a vertical empennage, makes wind energy conversion system remain state down with the wind.But, on the heavy-duty generator group,, thereby be not suitable for adjusting the angle down with the wind of wind energy conversion system with it because the volume and the weight of empennage is all bigger.Device such as generator, speed regulating mechanism all is arranged on cat head in the prior art, causes the maintenance trouble, and the load-carrying of tower is required also to have increased cost than higher.
The model utility content
The purpose of this utility model provides a kind of wind energy conversion system that can adapt to various wind directions, wind-force work.
For achieving the above object, the technical solution of the utility model provides a kind of wind energy conversion system, this wind energy conversion system comprises: main shaft, vane frame, blade, bearing, the quantity of described vane frame is at least three, and evenly be arranged on the main shaft is on the face in axle center, it is characterized in that: described main shaft is provided with perpendicular to ground, and the same side on described each vane frame is provided with at least one air deflector frame, and the side that is provided with air deflector frame in described each vane frame is provided with a blade by bearing.
Angle between air deflector frame described in the technical solution of the utility model and vane frame is 90 °～180 °, can fix a barge board on the described air deflector frame.
In the quantity of vane frame described in the technical solution of the utility model is even number greater than three, and described air deflector frame and vane frame be arranged in parallel, by same bearing a pair of mutually perpendicular blade are set on described every pair of symmetrical blading frame.
The wind energy conversion system that the utility model proposes has the following advantages:
1. the main shaft of wind energy conversion system is provided with perpendicular to ground, can be connected work with the generator that is arranged on ground, speed regulating mechanism, has reduced the load-carrying of tower, but and convenient for maintaining; And no matter be in which kind of wind direction, always main shaft there is the blade wind-engaging power effect on the vane frame of a side direction be closed on this vane frame, then the opening of opposite side makes main shaft one side stressed and rotate, thereby can adapt to various wind direction work;
2. the same side on each vane frame of wind energy conversion system is provided with at least one air deflector frame, and the scope of blade wind-engaging power effect rotation has been subjected to certain limitation like this, makes blade rotation more regular, and also having improved wind energy conversion system is the efficient of mechanical energy with wind energy transformation;
3. various wind directions of this wind-force functional adaptation and wind-force work can be installed in various places, are used for beautifying the environment.
