Description
Technical field:
Patent of the present invention relates to wind-power electricity generation, and particularly a kind of startup wind speed is low, the wind power generating set with vertical shaft that generating efficiency is high.
Background technique:
As everyone knows, wind energy conversion system is a kind of energy conversion device that wind energy is converted to mechanical energy, electric energy or heat energy, position difference by rotor shaft can be divided into horizontal-shaft wind turbine and vertical axis windmill, energy drives chain (being wind wheel, main shaft, speedup box, generator) in horizontal direction be referred to as horizontal-shaft wind turbine (Horizontal Axis Wind Turbine, HAWT).The energy drives chain become Vertical direction be referred to as vertical axis windmill (Verticaol Axis Wind Turbine, VAWT).
Horizontal-shaft wind turbine is that development both at home and abroad is maximum at present, modal a kind of wind energy conversion system, it also is the most ripe a kind of wind energy conversion system of technology, its wind wheel impeller number is generally 2～3 leaves, impeller shape is generally wing, and this wind wheel starting torque is bigger, the power coefficient height, for make sweep the wind face at any time facing the wind to, device for regulating direction need be housed.
Vertical axis windmill is applied in the human sphere of life very early, but because people generally believe that the starting torque of vertical axis rotor is little, wind energy utilization is low, thereby cause vertical axis windmill to can not get for a long time paying attention to.Along with improving constantly of development of science and technology and human knowledge's level, studies have shown that the vertical axis aerogenerator wind energy utilization and be not less than horizontal axis wind-driven generator that the mechanism of present many countries and individual are studying various vertical axis aerogenerators.Vertical axis windmill can be divided into two main types: a class is to utilize the aerodynamical resistance acting, and typical structure is a S type wind energy conversion system; Another kind of is the lift acting that utilizes aerofoil profile, most typical is Da Lie (Darrieus) type wind energy conversion system, the Da Lie wind energy conversion system have various ways as: Φ type, H type, Y type and rhombus are two kinds of straight impeller and bending impellers basically, are the typical case with H type, Φ type wind wheel.
There is following defective in above-mentioned existing wind generating technology:
The horizontal axis wind-driven generator complex structure, Installation and Debugging are difficult in maintenance, manufacture cost is high, the anti-ability of decreasing, and certain noise pollution is arranged, show as: (1) is from the impeller force analysis, be subjected to front wind load power, centrifugal action on the horizontal axis paddle, RANDOM WIND load reaches tens tons, and the similar overhang of blade wheel structure, the moment of flexure stress that the impeller root is subjected to is very big, and a large amount of accidents all are that the impeller root fractures; (2) when wind speed changes, in order to regulate rotating speed, hydraulic pressure closed-loop adjustment control system is installed regulates the slurry distance, promptly under wind load, rotate angle of paddle, this system accuracy height, price is expensive, maintenance is difficult; (3) for realizing the rational Match of rotating speed, design has 50～100 tons the multi-stage planetary gear gearbox of weighing, its transportation and that the difficulty of lifting is installed is very big, and cost is very high; (4) the horizontal axis set engine room is placed on the top of high tower, is one rotatable 360 ° activity system of connections.Its center of gravity height, structural instability causes installation and maintenance inconvenience.
2. the vertical shaft wind force motor has characteristics such as, Security height lower than horizontal axis wind-force electrical machinery noise.The general vertical axis windmill regulating system of facining the wind can be accepted in 360 ° of orientation any direction and the wind comes from, and rotate towards the direction of design all the time; Blower fan do not need closed loop hydraulic distance-regulating system, do not need impeller facing the wind regulating system, without any need for the vscf generator of automatic control speed control system or particular design.In the whole wind speed range of generating electricity to electrical network output same frequency, with voltage; The supervisory system that does not need overload, Over Current Protection System and the complex and expensive of generator; The gear-box of generator is placed on the bottom, and center of gravity is low, and is not only stable, and easy to maintenance; Blower fan pylon can be fixed with cable wire, thereby manufacture cost reduces greatly, but shortcoming such as vertical axis aerogenerator ubiquity startability is poor, and operational efficiency is low, this all is a difficult problem to cross over global wind generator set design field.Be made up of the half round post of two axis misalignment as S type blower fan (windage type), its advantage is that detent torque is big, and shortcoming is that (1) rotation speed of fan is low, and its tip-speed ratio is less than 1, so wind energy utilization is low, transformation efficiency coefficient Cp is about 0.3; (2), thereby it is produced lateral thrust owing to produce asymmetric air-flow round wind wheel.For relatively large wind energy conversion system, owing to be subjected to the restriction of deflection and ultimate stress, adopting this structural type is the comparison difficulty.And the lift-type blower fan can reach 0.45～0.55 as Da Lie wind energy conversion system (tip-speed ratio 4～5) its wind energy utilization height when the high rotating speed.But shortcoming is that (1) starting torque is little, can not self-starting (2) speed governing, the speed limit difficulty.
Summary of the invention:
The purpose of patent of the present invention is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of starting torque is big, generating efficiency is high, the wind power generating set with vertical shaft of long service life.
Patent of the present invention can reach by following measure:
A kind of wind power generating set with vertical shaft, comprise support, generator, impeller, impeller is made up of blade, spoke, wheel hub and main shaft, blade is connected on the spoke, and spoke is connected on the wheel hub, and wheel hub can be around main axis rotation, it is characterized in that impeller is H type and vertical the installation, generator is connected with main shaft, and main shaft is a vertical shaft, and automatic driftage brake arrangements for speed regulation are housed on the main shaft.
The present invention's brake arrangements for speed regulation of going off course automatically are installed in the top of main shaft, and box haul and rotational speed regulation are controlled the angle of attack that facings the wind of vertically arranged impeller; Thereby impeller is transferred to drive generator at the wind-drive backspin and is rotated the purpose that reaches generating.
Patent impeller of the present invention adopts H type airfoil fan, spoke adopts the triangle spoke, upper and lower pair of fulcrum of spoke and wheel hub is connected, blade and spoke adopt and flexibly connect, and can swing around bearing pin, and its swaying direction and position are subjected to the control of driftage brake speed control system automatically, owing to adopted the two fulcrum designs of vertical vane and triangle, make main force bearing point concentrate on wheel hub, therefore solved problems such as leaf abscission, fracture and blade fly out well, prolong working life.
