Description
Technical field
The invention belongs to technical field of wind power generation, specifically, particularly helical blade type wind power generation device.
Background technique
Be transformed into the most basic a kind of mode that electric energy is Wind Power Utilization to wind energy.The principle of wind-power electricity generation is to utilize wind-force to drive the air vane rotation, through booster engine rotational speed is promoted again, drives generator for electricity generation.
Because wind-power electricity generation does not have fuel problem, can not produce radiation or atmospheric pollution, so wind-power electricity generation has generally been admitted and widelyd popularize application in the whole world yet.Along with deep, the scientific and technological progress of research, wind generating technology is also in continuous progress.
The simplest wind-driven generator can be made up of impeller and generator two-part, stands on the pylon of certain altitude, and this is small-sized from the net blower fan.The electric energy that initial wind-driven generator sends changes with the wind and cuts in and out, and voltage and frequency are unstable, do not have actual application value.Modern blower fan has increased gear-box, yaw system, hydraulic system, brake system and control system etc., though solved the stable problem of voltage and frequency, but still not enough below existing:
1, parts such as impeller, gear-box are arranged on tower masthead portion, and installation and maintenance all need be carried out high-lift operation, not only installation and maintenance difficulty, and expensive, and only lifting cost at every turn will ten of thousands unit.
2, be straight line type from impeller, gear-box to the transmission of generator, bulky, impeller height-limited, and be difficult to accept disorderly stream wind-force.
3, the blade of blower fan is generally 2 leaves or 3 leaves, in order to catch the wind of any wind direction, must increase empennage or wind direction guider, and head is swung constantly in order to aim at wind direction, has increased rate of fault.
4, in order to absorb more wind energy, impeller diameter will be done very greatly, has not only increased manufacture difficulty and manufacture cost, and it is big to take up room, and Installation and Debugging are inconvenience very.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of helical blade type wind power generation device that is easy to installation and maintenance.
Technological scheme of the present invention is following: a kind of helical blade type wind power generation device; Comprise blade, step-up gear and generator; Wherein the input end of generator is connected with the output terminal of step-up gear; Its key is: the input end of said step-up gear is connected with the output flange of axle bottom, and this is supported on the bottom of support through bearing, and the top of axle is docked with the bottom of blade column and fixed; The top of said blade column is supported on the top of support through bearing, and the top of support is provided with the air-out passage; On said blade column, blade is set, this blade is positioned at support, and along the blade column axially in the shape of a spiral shape spiral.
As everyone knows, wind-power electricity generation at first is the absorption of wind energy, and the structure of impeller and performance are directly connected to the absorption of wind energy, so impeller is the primary critical component of wind-powered electricity generation.The energy that fan blade obtains from the motion of wind is directly proportional with the cube of wind speed; Except that wind speed, the blowing area of impeller diameter or blade has determined the number of fechtable wind energy, and approximately the lifting surface area with impeller diameter square/blade is directly proportional; The number of blade also can have influence on the output of blower fan.
Therefore, the present invention adopts support and spiral blade to form impeller, and the shape of cross section of blade is similar to the aerofoil profile of wing; And along the blade column axially in the shape of a spiral shape spiral; Can catch the wind of any wind direction, let wind cross blade and produce the both sides draught head and blade is rotated around central axis, along with the blade rotation; The guiding air up flows, and the air-out passage from a top of the trellis flows out at last.When blade and blade column rotate, give step-up gear with transmission of power, pass to generator by step-up gear again, make generator carry out generating work through the axle of blade column bottom.Blade and blade column are positioned at support, can bear the wind-force (that is to say wind-engaging not to restriction) of a plurality of directions, and wind energy utilization is high.Compare with traditional high tower electricity generating device, structure of the present invention is simpler, and cost is lower, and installation and the height of safeguarding are low, has both reduced the difficulty of installation and maintenance, has reduced correlative charges again.
Said support is made up of ceiling hold, bracket upright post and base; Wherein ceiling hold be positioned at base directly over; The middle part of base is through the bearing supporting axle, and the middle part of ceiling hold is through bearing and the supporting of blade column, and ceiling hold is provided with the air-out passage; Between said ceiling hold and base, be connected with many bracket upright post, each bracket upright post is positioned at the outside of blade.More than simple in structure firm, easy to assembly, quick, can guarantee to catch the sensitivity of wind-force.
For the ease of manufacturing, guarantee the stability of impeller, the profile of said ceiling hold and base is circle or rectangle, and the bracket upright post between ceiling hold and base is rounded, equilateral triangle, square or limit number distribute greater than four regular polygon.
Between the two adjacent stent columns of the said blade outside, be provided with and be the stiffening rib that " * " shape distributes.Connect into an integral body through stiffening rib between the bracket upright post, structural strength is good, can not deform or damage, and working life is secure.
On the face of blade column, be provided with wind deflector in said bracket upright post; The length direction of this wind deflector and bracket upright post axially in the same way; And the direction of the thickness of wind deflector from bracket upright post to the blade column reduces gradually, and the wind deflector on two adjacent stent columns forms " eight " font structure, and osculum is towards blade; Have the effect of gathering, guiding, can guide the wind-force pick up speed to blow to blade.
Said base is supported by platform, and this base is fixed through bolt and platform; Said platform is arranged at ground or roof, and is positioned at the top of step-up gear and generator.The present invention can be loaded under the environment such as outside wind field, ocean like this, also can be used for roof, incity, city, accepts disorderly stream wind-force, and using scope is very extensive.
Said generator is positioned at the next door of step-up gear, and the axis of the axis of this generator input end and step-up gear output terminal is on same straight line, and is and perpendicular with the axis of step-up gear input end.More than simple in structure, compact, be " L " type from impeller, gear-box to the transmission of generator, on the one hand effectively reduced volume, on the other hand, reduce or to increase impeller height easy.
Said blade column is cylindrical or conical hollow tube, not only simple shape, draw materials conveniently, cost is low, and can effectively reduce the weight of impeller.
Said blade is single head, double end or multi-head spiral shape blade.Under the situation of same diameter, single head, double end or multi-head spiral blade have bigger blowing area than 2 traditional leaves or 3 leaf blades, can absorb more wind energy in the unit time, have improved the absorption efficiency of wind energy.
Beneficial effect: the present invention is simple in structure, installation and maintenance are easy, volume is little, cost is low, can bear the wind-force of a plurality of directions, and the ability of seizure wind-force is strong, and the wind energy absorption efficiency is high.Impeller both can horizontal positioned, also can vertically place, and can install and use in multiple different place.
