Abstract
The invention designs a lift force blade system for an aerogenerator, which belongs to the field of generators and is an improvement for a vertical blade aerogenerator. The lift force blade system comprises vertical blades, an upper circular ring, a lower circular ring, a center shaft, fly ball components and lift force blades, wherein two ends of the vertical blade are fixed on two circular ring components respectively, and the two circular ring components are fixed on a generator input shaft through a spoke to form a stable pulling force system; and the top of the blade and the center shaft connected with the generator input shaft in the lower circular ring are provided with a plurality of the lift force blades rectangular with the vertical blades, and an attack angle of the blades is designed with variable distances and is controlled by one or more groups of the fly ball components. The lift force blade system uses few materials and has light weight; and the rotation of the lift force blades generates lift force to cancel out the gravity generated by the lift force system, and the axial frictional resistance is reduced to the minimum to improve the efficiency of a vertical shaft wind generator system.
Description
Technical field:
The present invention relates to a kind of wind-driven generator, particularly a kind of fixed structure of vertical axis aerogenerator.
Background technique:
Entered since 21 century, along with the whole world to the protection environment with rationally utilize the raising of attention degree of the concept of renewable energy sources, more and more the renewable energy utilization technology is developed.
China just begins to research and develop vertical axis aerogenerator in calendar year 2001, and it is very ripe and promising that this technology has been proved to be.But because the structural feature of vertical axis aerogenerator, system has a big chunk energy to be fallen by system's autophage in generating.Since the axial rub drag effects that lift force blade gravity produces the generating efficiency of system, in order to address this problem, invented a kind of magnetic suspension bearing, offset the frictional force of gravity generation with the same sex characteristics of repelling each other of permanent-magnet material.This system has solved the problem of surface friction drag, has brought the problem of the manufacture cost increase of vertical axis aerogenerator again.
Summary of the invention:
The objective of the invention is to solve the described problem of background technique, design a kind of blade system of in light weight, band lift structure that intensity is good,, improve generating efficiency to reduce axial friction.
Vertical vane of the present invention two ends are separately fixed on two annulus members, and these two ring members are fixed on the generator input shaft by spoke, form a stable pulling force system.On in the top of blade and bottom annulus and the central shaft that the generator input shaft is connected, be provided with multi-disc lift force blade and vertical vane and meet at right angles, but the angle of attack of blade is the displacement design, by one or more groups flyball component controls.
The spoke structure substitutes support force with pulling force, and is reliable and stable, and the raw material ratio section bar is fixing less, in light weight, reduced the weight of whole system; The rotation of lift force blade produces lift, the flyball parts change the adjusting of implementing the lift force blade angle of attack by the centrifugal force in rotary course, reach optimum angle of attack, offset the gravity that lift force blade system produces, the axial rub resistance is reduced to minimum, improves the efficient of vertical axis wind power generation system.
Description of drawings:
Fig. 1 is a structural front view of the present invention
Fig. 2 is the plan view of structure of the present invention
Embodiment:
In conjunction with Fig. 1, Fig. 2 concrete structure of the present invention is described.The present invention contains vertical vane 1, last annulus 2, following annulus 3, central shaft 5, flyball parts 7, lift force blade 6, vertical vane 1 two ends are separately fixed on two annulus members 2,3, these two ring members are fixed on the generator input shaft 5 by spoke 4, form a stable pulling force system.We know that in physics the pulling force stability of a system is better than pressure system.In this system because blade no longer is a mechanics member in the mechanics fixed system, and just wind energy accept parts, structural strength can reduce greatly.The reduction of the spoke of pulling force system and blade structure intensity means the minimizing of the system weight of same material.Same principle, the axial rub resistance of system also will reduce, and vertical axis wind power generation system efficient also will be improved.Because the requirement of the structural strength of blade itself reduces, just make that the range of choice of blade material is enlarged on the other hand, reach the purpose that reduces the vertical axis wind power generation system cost.
On the axle 5 that is connected with the generator input shaft in the top of blade 1 and the bottom annulus 3, be provided with multi-disc lift force blade 6 and vertical vane 1 meets at right angles.But the angle of attack of blade 6 is the displacement design, by one or more groups flyball parts 7 controls.But adopted similar helicopter displacement propeller cavitation lift system here.Flyball parts 7 change the adjusting of implementing lift force blade 6 angles of attack by the centrifugal force in rotary course, reach optimum angle of attack, offset the gravity that the rotation blade system produces, the axial rub resistance is reduced to minimum, improve the purpose of vertical axis wind power generation system cost.
Adopt the vertical axis wind power generation system of this patent, can substitute or cancel the permanent magnetism magnetic suspension bearing arrangement, lower the manufacture cost of vertical axis wind power generation system, improve generating efficiency.
