Abstract
The invention discloses a maglev Savonius rotor wind power generator blade, which comprises a rotating shaft, rigid fins, blades and a base disk, wherein the rotating shaft passes through the base disk and is fixed thereon; the blades are uniformly arranged on the base disk along the circumference; the side faces of the blades are fixed on the rotating shaft; and a series of rigid fins forming a certain angle with the blades are fixed on the inner sides of the surfaces of the blades. The projection of the blades in the vertical direction is a curve of which the curvature is constantly decreased outwards along with the axis, so the trust of wind to the blades is increased; and the rigid fins are arranged on the blades, the thrust of wind to the blades is increased, and the efficiency and the wind utilization rate are better improved.
Description
Technical field
The present invention relates to a kind of magnetic suspension Savonius rotor blade of wind-driven generator.
Background technique
Wind energy is a kind of renewable energy sources of cleaning.Solar radiation is the main reason of wind to the nonuniformity heating of earth surface.At present, along with the growing interest of various countries to problems such as environmental protection, energy shortages, the wind-power electricity generation industry has been subjected to increasing attention.Wind wheel blade is the basic element of character of accepting wind energy, is the parts of the most basic and most critical in the wind-driven generator, and its good design, quality and superior performance are the determinant factors that guarantees the normal stable operation of unit reliably.The quantity of the aerofoil profile of blade and distortion, blade and tip-speed ratio all directly influence the efficient that blade receives wind energy.Major requirement to blade has: density is little, mechanical property and fatigue strength are good, can stand exceedingly odious conditions such as storm wind and random load etc.
The Sa Funiusi wind energy conversion system is a kind of resistance-type vertical axis wind turbine.It has the peculiar advantage of all vertical axis aerogenerators: 1) wind turbine tower is simple in structure, need not wind apparatus; 2) generator driving mechanism and control mechanism etc. install on ground or the low latitude, and maintenance maintenance is convenient; 3) blade is made easily, cost is low.These advantages can reduce the research and development and the manufacture cost of vertical axis aerogenerator, are easier to vertical axis aerogenerator and promote in low wind speed districts such as cities.This wind energy conversion system is a S type blade, and it is simple to have a mechanism, characteristics such as starting torque is big.But this shaft resistance type windmill is compared with lift-type wind energy conversion system (as modern propeller type horizontal-shaft wind turbine), and power factor is lower, and tip-speed ratio is little.Thereby use seldom, just be used for irrigation by pumping etc. in rural area and remote districts.In recent years, because the fast development of generator techniques, some are applicable to that the generator of slow speed wind energy conversion system constantly occurs, and this provides the chance of using just for the Sa Funiusi wind energy conversion system, makes it can be applied in small capacity on net type wind-power electricity generation.
It is semicircle that the cutting plane of existing Savonius rotor blade of wind-driven generator mostly is, this blade structure is lower to the utilization ratio of wind, on some direction, the power of blowing of wind can become resistance on the contrary, and do not have in the blade structure of rigid fin structure, because the air ventilation path is simple, wind-force is not carried out multistage utilization, further is unfavorable for the raising of efficient.
Summary of the invention
The objective of the invention is to overcome prior art apoplexy utilization ratio deficiency, a kind of magnetic suspension Savonius rotor blade of wind-driven generator is provided.
A kind of magnetic suspension Savonius rotor blade of wind-driven generator is characterized in that comprising rotating shaft, rigid fin, blade and base disk; Base disk and fixed thereon is passed in rotating shaft, and blade is evenly distributed on the base disk along circumference, and the side of blade is fixed in the rotating shaft, and rigid fin is fixed in the blade surface inboard.
Use the present invention, because the projection on the vertical direction of blade is that curvature is with the outside ever-reduced curve in axle center, increased the thrust of wind to blade, be arranged with rigid fin on the blade, increase the thrust of wind to blade, produced the air flow channel in blade, better increased efficient and the utilization ratio of wind.
Description of drawings
Fig. 1 is magnetic suspension Savonius rotor wind-driven generator three blade structure schematic representation of the present invention;
Fig. 2 is magnetic suspension Savonius rotor wind-driven generator three blade structure plan views of the present invention;
Among the figure, rotating shaft 1, rigid fin 2, blade 3, base disk 4.
Embodiment
Shown in Fig. 1～2, array-type magnetic suspension Savonius rotor blade structure for wind driven generator comprises rotating shaft 1, rigid fin 2, blade 3 and base disk 4; Base disk 4 and fixed thereon is passed in rotating shaft 1, and blade 3 is evenly distributed on base disk 4 along circumference, and the side of blade 3 is fixed in the rotating shaft 1, a series of rigid fin 2 and blade 3 angled blade 3 inner side surfaces that are fixed in.
Shown in Fig. 1～2, blade 3 can be for one or more, and the projection on blade 3 vertical directions is not traditional semicircle, but curvature is with the outside ever-reduced curve in axle center.
Shown in Fig. 1～2, a series of rigid fin 2 that is being intervally arranged on each blade 3 so that each is carried out multistage utilization to wind-force, better increases efficient.
