Description
Technical field
The invention belongs to field of renewable energy, relate to a kind of wind-driven generator, particularly vertical axis aerogenerator.
Background technique
Wind-driven generator is varied, but is summed up and can be divided into two classes: 1. horizontal axis wind-driven generator, and the running shaft of wind wheel is parallel with wind direction; 2. vertical axis aerogenerator, the rotational axis vertical of wind wheel is in ground or airflow direction.Horizontal axis wind-driven generator section is divided into lift-type and resistance type two class.Lift-type wind driven generator rotation speed is fast, and resistance type rotational speed is slow.For wind-power electricity generation, many employing lift-type horizontal axis wind-driven generators.Most of horizontal axis wind-driven generator has wind apparatus, can change and rotate by box haul.For small-sized wind power generator, this to wind apparatus employing tail vane, and for large-scale wind-driven generator, then utilize the driving mechanism of wind direction sensor and actuating motor composition.The wind wheel of wind energy conversion system is called upwind wind energy conversion system before pylon, and wind wheel then becomes leeward to blower fan after pylon.The style of horizontal axis wind-driven generator is a lot, the wind wheel with counter-blades had, multiple wind wheel installed by another pylon had, to reduce the cost of pylon under the condition that output power is certain, the horizontal axis wind-driven generator also had produces whirlpool around wind wheel, focused airflow, increases airspeed.Vertical axis aerogenerator is when change of the wind without the need to wind, and be a large advantage relative to horizontal axis wind-driven generator in this, it not only makes structural design simplify, and decreases wind wheel to gyro power during wind.
The vertical axis aerogenerator utilizing resistance to rotate has several types, and wherein have the wind wheel utilizing flat board and quilt to make, this is a kind of pure resistance device; S type windmill, has part lift, but main or resistance device.These devices have larger starting torque, but tip-speed ratio is low, and when wind wheel size, weight and cost are certain, the power stage provided is low.
In addition, also have some other mutation, such as reach inner luer wind wheel.Reaching inner luer wind wheel is a kind of lift unit, and the section of curved vane is aerofoil profiles, and its starting torque is low, but tip-speed ratio can be very high, for given wind wheel weight and cost, has higher power stage.Have now and multiplely reach inner luer wind-driven generator, as Φ type, Δ type, Y type and H type etc.These wind wheels can be designed to single blade, double-leaf, Three-blade or multiple-blade.Other forms of vertical axis aerogenerator has Magnus effect wind wheel, and it is made up of the cylindrical body spinned, and when it works in the gas flow, the locomotivity of generation causes due to Magnus effect, and its size is directly proportional to wind speed.Some vertical axis rotors use pipeline or eddy generator tower, make horizontal gas flow become uprush by sleeve pipe or Diffuser, to gather way, occasionally write and also utilize solar energy or certain fuel that burns, make horizontal gas flow become the air-flow of Vertical direction.
The wind wheel of these generators is all be directly exposed in wind and rain, is easily drenched with rain, and need to use special material, the life-span is also affected.In addition, wind wheel is all passively accept wind energy, can not accept the size of wind energy by regulation and control.In addition generator receptible wind energy be subject to leaf blade size and shape restriction, fully can not accept wind energy.Existing wind-driven generator could can only generate electricity when wind-force is enough large in addition.Existing wind-driven generator can only utilize the positive pressure of wind, and can not utilize the negative pressure of wind.
Summary of the invention
The present invention is directed to the above defect of existing wind wheel generator, design a kind of wind-driven generator be placed in by wind wheel in shell, by regulating the size of shell intake grill.Very long in the wind wheel length of traditional wind, blade is not wide, not intensive, owing to relying on shell to concentrate wind energy in the present invention, like this without the need to blade being done can accept very greatly the concentrated wind energy power of shell, enough wind energy powers can be just put aside when wind-force is more small, even if width of blade is large, than comparatively dense, also without the need to very large area.Vertical axis aerogenerator often needs wind apparatus, according to the direction of Wind direction-adjusting device, can there is more cost like this.In the present invention wind wheel towards being fixing, without the need to rotating, without the need to special connection set, this can extend its life-span, reduces the requirement of special material.The impeller (wind wheel) of traditional wind is placed in open space, this is also unfavorable for making full use of wind energy, such as when wind energy deviate from the direction of wind wheel, cannot be utilized, impeller is placed in a closed pipeline by the present invention, wind energy is not changed completely through a wind wheel, can promote wind wheel generation in the next wind wheel of pipeline yet, can improve the utilization ratio of wind energy.Key of the present invention is: wind wheel and accessory generator thereof are placed among a shell, this shell is divided into many fans, all can open wide towards all directions, but, the non-return device of a similar valve is all had at these fans of shell, in wind, unlimited, time leeward, can automatically close, as long as have wind like this, no matter wind from which direction comes, all can only enter electricity generating device inside from shell, promote one group of wind wheel generation be arranged on bearing, and can not go out from the intake grill of device.When wind comes from certain direction time, only have those or that fan of wind in the face of direction to be open, as long as other pressure direction is contrary, will automatically close.Each fan of shell is all in fan-shaped, each sector region is closed up and down, and that one end, outside that wind is come in from the external world is comparatively large, and the basal area that wind enters the one-way cock of generator intake grill is less, along with the reduction of section after entering inside, wind speed can increase.Then wind enters in the vertical pipe of a sealing, promotes impeller (wind wheel) group and rotates, then the speed rotated promoted through booster engine, impel electrical power generators.In order to make full use of the negative pressure of wind, strengthen wind speed, can arrange contrary non-return device at the outlet end of wind, form air negative pressure, namely windward side is closed, and lee face is opened, and such wind can be sucked out.
This wind-driven generator comprises: shell, intake grill, pipeline, bearing, wind wheel, one-way cock, exhaust outlet, enters interruption-forming malleation, goes out interruption-forming negative pressure, causes wind in vertical pipe, promote runner generating.
Because device does not adjust along with the change of wind direction, be fixing, so that can do is larger, face of collecting folk songs is very large.Wind wheel, by bearings, can bear larger wind-force.
