Abstract
The utility model relates to a vertical shaft type wind generator, and particularly to a vertical shaft type multistage-fan-blade wind generator which comprises the following components: a tower body at bottom, a power generator, a speed increasing box, a brake, a wind turbine equipped with fan blades, wherein the power generator, the speed increasing box, the brake and the wind turbine are successively provided above the tower body from bottom to top. The utility model is characterized in that: the fan blades are divided into at least two layers; each layer of fan blades are fixed on a shaft sleeve which is matched with a fixed shaft through a bearing; three fan blades are arranged along a circumferential direction of the fixed shaft in each layer of fan blades; and the fixed shaft is fixed on the tower body. The vertical shaft type wind generator has the following advantages: high wind energy utilization rate, large capacity of single set of the wind generator, simple structure, high firmness, convenient maintenance and high economic benefit.
Description
Technical field
The utility model relates to a kind of perpendicular axis type wind-driven generator, especially relates to the multistage fan blade wind driven generator of a kind of perpendicular axis type.
Background technique
Wind-driven generator has horizontal shaft type and two kinds of structures of perpendicular axis type at present, though the swept area of the power-driven generator leaf of horizontal shaft type wheel is big, the wind energy that acts on the fan blade is lower, and wind energy utilization is low; The generator of present horizontal shaft type wind-driven generator, gear-box, direction regulator, braking device etc. all are installed on the high pinnacle of a pagoda of 50-90 rice, and be both unstable along with wind energy conversion system is movable together, also very difficult during maintenance; The structure of perpendicular axis type has overcome above-mentioned defective, but the present air blade that has only individual layer of perpendicular axis type, thereby has influenced the wind energy utilization of wind-driven generator.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of wind energy utilization height, single-machine capacity is big, simple in structure, firm, easy to maintenance, economic benefit the is high multistage fan blade wind driven generator of perpendicular axis type are provided.
The utility model is realized in the following way:
The multistage fan blade wind driven generator of a kind of perpendicular axis type, body of the tower, body of the tower bottom it comprises up are combined with successively on generator, speedup box, braking device, wind energy conversion system, the wind energy conversion system air blade are installed, and it is characterized in that: above-mentioned air blade is at least two-layer;
Described every layer of air blade all is fixed on the axle sleeve, and described axle sleeve cooperates with stationary axle by bearing, and every layer of air blade circumferentially is distributed with three along described stationary axle, and described stationary axle is fixed on the described body of the tower;
The oblique triangular cone of the hollow that described each air blade is a recording quantity, the triangular cone of hollow are can to link together by draught spring and its lap by movable face by one;
The part of the hollow that described each air blade opens wide is in face of wind direction;
The face of a sealing of described each air blade one end is vertically fixed on the described wind energy conversion system;
Described air blade be two-layer, three layers or four layers.
The utility model has following effect:
1) blowing area is big, wind energy utilization is high: the blade that the utility model provides is the triangular taper that a face of hollow opens wide, and open surface facings the wind, and forms the whirlpool energy when wind acts on the blade, has increased the active force of wind on blade.Because the fan blade windward side is a bucket shape, the blowing area of fan blade is more than two times of actual air blade projection plane, and the whirlpool effect of wind in air blade in addition just improved the wind energy utilization of wind energy conversion system greatly, and air blade is sharp cone distal dorsad, thereby the resistance of wind is very little.Air blade is double-layer structure at least, has not only increased blowing area, and has improved wind energy utilization.
2) long service life, cost are low; The device that the utility model provides, because air blade is the triangle-frame structure, warping resistance intensity height, long service life, the length of air blade can be longer than the air blade of horizontal shaft type wind-driven generator, and more likely the direction to big capacity wind-driven generator develops, and the utility model need not be to wind apparatus, thereby can simplify airframe structure, thereby reduce cost.
3) the running middle machine body is stable, easy to maintenance: the device that the utility model provides, and body of the tower is fixed on ground, and the main shaft of wind energy conversion system, speedup box, generator, braking device etc. all are installed on the body of the tower, make whole fuselage more stable and stronger, keep in repair very convenient.
4) speed governing is simple, reliable: the device air blade that the utility model provides is the triangular centrum of the not contour hollow of recording quantity, the triangular centrum of hollow is can to link together by draught spring and its lap by movable face by one, and movable face becomes the speed governing blade; Speed governing blade two ends connect by draught spring, like this when wind speed surpasses 25 meter per seconds: air blade is pushed open by wind, this moment, wind energy conversion system slowed down, and below cut-out wind speed 25 meter per seconds, move, when wind speed air blade auto-closing during less than 25 meter per seconds, the pulling force of two ends spring just in time is the thrust of 25 meter per second wind speed: this kind arrangements for speed regulation are simply effective.
