Description
Technical field
This patent includes a kind of wind generating unit in clean energy resource field, has especially adopted the wind-force of bionical variable-vane wind-exposuring area to receive the wind-driven generator of blade.
Background technique
Due to day by day consuming and the mineral fuel serious problems such as the environmental pollution that brings of generate electricity of the nonrenewable resources such as oil, coal, increasing country is studied and application aspect has dropped into a large amount of manpowers and fund at renewable resources.Wind energy be a kind of at a low price, clean, environmental protection, convenient, the energy of " inexhaustible ", be the renewable resources of tool exploitation prospect at no distant date.
Wind power generating set mainly comprises horizontal axis wind-driven generator and perpendicular axis type wind-driven generator at present, compare with horizontal axial type wind-driven generator, the feature of perpendicular axis type wind-driven generator is that running shaft is perpendicular to the ground, the plane of rotation of wind wheel is parallel with wind direction, in rotary course, be subject to force direction constant, without regulating system windward, its reliability is high, and will be longer than horizontal axial type generator fatigue life.And vertical axis aerogenerator can be placed on far even ground, wind wheel bottom, be convenient to installation and maintenance.
Wherein, Dari eritrea type (Darrieus) wind energy conversion system belongs to perpendicular axis type wind-driven generator, is mainly made up of rotor blade, gearbox, generator, drag-line, top, bottom rotor center etc.Blade top is connected with top rotor center, and bottom is connected with bottom rotor center, rotor blade rotarily drive vertical shaft rotate, rotating shaft after gearbox speed change by transmission of power to generator, thereby realize generating function.Because the horizontal radius of this wind mill rotor blade is larger, rotating shaft is higher, for solving the strength problem because caused by large wind, adopts drag-line to be fixed on ground from top, has caused to a certain extent location space waste; And for king-tower cylinder spring bearing, need to bear huge radial and axial load, up-down vibration equally also can produce a series of alternate loads etc.; In addition, once power generating equipment breaks down, maintenance and maintenance are all cumbersome, and its time is long, and efficiency is low.
The vertical axis aerogenerator of the type is ripe at present, and there are low advantages such as maintenance that are easy to of its cost simple in structure, but maximum problem is the structural limitations due to blade, causes generating efficiency low, especially has great restriction for high-power generator unit material, construction cost etc.
Summary of the invention
The object of this patent is the deficiency overcoming in prior art; a kind of bionical vertical axis aerogenerator is provided; it is simple in structure; easy to maintenance; do not need the auxiliary devices such as the pitch-controlled system of common three vane windpower engines; floor space is little and high to the conversion ratio of wind energy, also has self-protecting function, has avoided king-tower barrel structure middle (center) bearing to transship stressed problem.
The main body of this patent is the blade of vertical wind wheel, and " open-the closing-open-close ... " of the bionical wing in birds moved and coordinated variation in rotary course to complete the work of wind-driven generator.Wind wheel blade adopts three or more flexible variable wind-exposuring area blade, and in the time that it is worked windward, blade wind-engaging power effect note invests on the support of support and mesh-supported structure, therefore forms a complete plane; In the time that its revolution is met to wind direction, blade opens and is parallel to wind direction, is reduced to the state of resistance minimum.
The structure of bionical vertical axis aerogenerator is that plane of rotation is parallel with the direction of wind-force, does not need the pitch-controlled system of conventional wind power generator, and the precision of processing has been simplified and reduced to structure and component.Therefore its cost is low, has certain anti-typhoon capacity and adaptive performance.Bionical vertical axis aerogenerator comprises vertical wind wheel, planetary gear train speed increaser, coupling and high-speed drive shaft, caliper brake, variable-speed controller, generator, frame main body and rotary support.On vertical wind wheel, have three or multiple wind-force plate, each wind-force plate arranges arranges multi-disc flexible blade, and every blade is all connected with wind-force plate by blade installation shaft, windward time, flexible blade is opened, be attached on the metallic sieve of wind-force plate, thereby form moment with fair wind, drive wind wheel to rotate.Vertical wind wheel and rotary support, rotary support and frame main body are all to pass through Bolt Connection, vertical wind wheel rotates, through rotary support, power is passed to planetary gear train speed increaser, after speedup, power is at a high speed transported to generator, complete wind energy and arrived mechanical transformation of energy, be finally converted to electric energy.
Wherein, wind wheel is automatically realized for each and is arranged rotating freely of blade in rotary course, it is reached in a side windward and together launch completely to realize large size choke formula with fair wind; Turn round against the wind a lateral lobe sheet closing to a certain extent occurs arriving, thereby forming the almost rotating cycle of non-resistance alternately changes, and reaches wind wheel and adapts to the strong and weak regulation and control variation that changes and form the ability of exerting oneself of wind-force.
The beneficial effect of this patent is that the wind-exposuring area that this wind-driven generator reception blade area can be adjusted blade according to the geographical position of different geographical, wind energy density is to reach different generating effects.This design has automatic safety device, exceedes design wind speed and has certain collapsing force once wind-force, can change blade wind-exposuring area and will carry out the adjustment of wind-exposuring area, or completely de-ly put rear formation protection.
This bionical vertical axis aerogenerator automatical control system can detect and control adjustment gear according to wind friction velocity and realize 50Hz electric power networking condition, and realizes as possible the best generating efficiency under different wind conditions.
This bionical vertical axis aerogenerator does not need conventional wind-driven generator pitching device and control system, and general structure has been simplified the supplementary equipment such as wind direction regulating and controlling mechanism, can be according to the different condition such as wind condition and geographical position, and Modulating Power scope as required.
Flexible blade connecting rope can be controlled the closing device of windward blades, changes blade frontal resistance, reduces minimum drag.
