Abstract
The utility model relates to a vertical-shaft wind return type breeze generator, belonging to the field of renewable energy sources and comprising two groups of wind turbines rotating around a vertical shaft, wherein a wind baffle and a wind return groove are arranged at the front of each group of wind turbine; and a half of wind at the front of the wind turbines is guided to the rear parts of blades by the wind return grooves, so as to push blades at the other side from the rear part and generate a pure torque, so that not only is the overturning moment eliminated, but also the torque is increased. Two group of wind turbines are respectively positioned at the two sides of the two symmetrical wind return grooves A; the middle of the wind return grooves is provided with a vertical shaft B which can enable the wind return grooves, the left wind turbine and the right wind turbine to rotate around the vertical shaft B, so as to adapt to the change of the wind direction; each group of wind turbine is provided with four arc-shaped blades I; the jackets of the vertical shafts in the middle of the wind return grooves are provided with two supporting rods C; the lower ends of the supporting rods, the left wind turbine and the right wind turbine are provided with rollers which can roll along round guide rails at the bottom; and the upper ends and the lower ends of the two wind turbines and the wind return grooves are provided with upper cover plates and lower cover plates.
Description
Technical field
The invention belongs to the renewable energy source domain, by 2 groups of wind energy conversion system generatings around the vertical shaft rotation of vertical ground, every group of wind energy conversion system formed with upper blade and return duct of a barge board by 3; This mechanism can be converted into electric energy with the wind energy of faint wind.
Background technique
Wind energy more and more is subjected to the attention of countries in the world as a kind of renewable energy sources of cleaning.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 * 10
9MW, wherein available wind energy is 2 * 10
7MW is also bigger 10 times than the water energy total amount that can develop on the earth.
Present wind-driven generator, major part are that a horizontal axis is arranged on the upright bar, and axle head has 3 blades, and wind-force promotes the blade rotation and generates electricity by gear transmission drive generator.More than 50 ton of 1500 kilowatts blower fan cabin gross weight, 30 tons in impeller, making such system aim at prevailing wind direction at any time also has suitable technical difficulty.
Horizontal axis wind-driven generator must have driftage and cable-releasing equipment, and vertical axis windmill does not then need driftage and cable-releasing equipment, and the wind energy transformation rate of vertical axis windmill unit area is about about 50%, horizontal axis propeller wind power machine wind energy transformation rate about about 25%.
The gentle breeze-driven generator that the small part vertical shaft is also arranged, but all be that single face is stressed, there is tilting moment, whole efficiency is not high yet.
Summary of the invention
The present invention is a vertical shaft air-return gentle breeze-driven generator, this gentle breeze-driven generator has 2 groups of wind energy conversion systems that rotate around vertical shaft, there are a barge board and a return duct in every group of wind energy conversion system front, with half wind guiding forward of wind energy conversion system front backward, promote the blade of opposite side, make it to produce a torque in the same way, both eliminated tilting moment, increased torque again, improved generating efficiency, 2 groups of wind energy conversion systems lay respectively at the both sides of the return duct of 2 symmetries, a vertical shaft that can make return duct and left and right sides wind energy conversion system around its rotation is arranged in the middle of the return duct, and adapting to the change of wind direction, return duct intermediate vertical axle outer put 2 poles, there is guide wheel the lower end of pole, can roll along the circular guideway of bottom, the lower end of left and right sides wind energy conversion system also has roller to roll along guide rail, and every group of wind energy conversion system has 4 arc shaped blades, there is upper cover plate the upper end of two wind energy conversion systems and return duct, and there is lower cover plate the lower end.
The size of this wind energy conversion system is changeable, both has been suitable for the small generator of several hectowatts, also is suitable for large-scale wind power station.

Embodiment
As shown in Figure 1, H is the rotating shaft of 2 wind energy conversion systems, lay respectively at the both sides of 2 return duct A, left and right sides wind energy conversion system respectively has 4 arc shaped blade I, under the effect of wind-force, rotate around separately running shaft H, drive generator G generating, in order to adapt to the variation of wind direction, one vertical axis B is arranged in the middle of the return duct A of two symmetries, return duct and left and right sides wind energy conversion system can be turned about this axis, and for the balance tilting moment, vertical shaft has put 2 pole C outward, there is guide wheel D the lower end of pole, can roll along the circular guideway E of bottom.
As shown in Figure 2, the generator G of left and right sides wind energy conversion system is contained in the lower end of the running shaft H of wind energy conversion system, and the lower end of left and right sides wind energy conversion system has roller F to roll along guide rail E, and there is upper cover plate J the upper end of two wind energy conversion systems and return duct, and there is lower cover plate K the lower end.
The blade available metal plate roll forming of return duct and wind energy conversion system, 3 vertical shaft lower end installed thrust bearings, cover plate available metal plate is made up and down.
