Abstract
The invention discloses a blade overflow hole of a magnetic suspension savonius rotor wind driven generator. The blade overflow hole comprises a rotary shaft, overflow holes, blades and a base disk, wherein the rotary shaft penetrates through the base disk and is fixed on the base disk; the blades are uniformly arranged on the rotary shaft along the circumference; the side face of each blade is fixed on the rotary shaft, the bottom of each blade is fixed on the base disk; and the part, adjacent to the shaft, of the root of each blade is axially provided with a plurality of overflow holes. According to the invention, because the curvature of each blade decreases gradually from the axis center to the outward, the wind utilization ratio is increased, the assistance to the next blade by the utilized wind can be increased due to the overflows on the blades, blade resistance is reduced, and the secondary utilization process of the utilized wind is increased, so that the efficiency of the wind driven generator is improved greatly.
Description
Technical field
The present invention relates to a kind of overflow hole structure of magnetic suspension Savonius rotor blade of wind-driven generator.
Background technique
Wind-power electricity generation is the pollution-free generation mode of competing mutually with the traditional fuel generating. be the clean energy resource that is full of vitality.In recent years, the wind-power electricity generation industry development is rapid, and countries in the world wind-powered electricity generation electric motor power grows with each passing day.Along with the expansion in China wind energy market, the blower fan manufacturing industry progresses into high-speed development period.Impeller is most important, the expensive component of wind-driven generator, and single parts account for 20% of whole wind power generator cost, and the key of impeller then is a blade.
The Sa Funiusi wind energy conversion system is a kind of resistance-type vertical axis wind turbine.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.In addition, because its starting torque is big.Thereby can be used in combination with the wind energy conversion system of other startability differences, play complementation.
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 overflow hole structure, wind is during from radially the blowing of blade, and the wind that has been utilized can hinder the motion of next blade, has further reduced the utilization ratio of wind.
Summary of the invention
The objective of the invention is to overcome the low deficiency of prior art apoplexy utilization ratio, a kind of magnetic suspension Savonius rotor blade of wind-driven generator overflow hole is provided.
A kind of magnetic suspension Savonius rotor blade of wind-driven generator overflow hole is characterized in that comprising rotating shaft, overflow hole, blade and base disk; Base disk and fixed thereon is passed in rotating shaft, and in rotating shaft, the side of blade is fixed in the rotating shaft blade along circumferential arrangement, and the bottom is fixed on the base disk, and each root of blade all is provided with overflow hole vertically near the position of axle.
As improvement, described blade be curvature from the axle center outside ever-reduced curvilinerar figure.
As further improvement, be provided with an overflow hole on described each blade at least.
Use the present invention, since the curve form of blade be curvature from the axle center outside ever-reduced curvilinerar figure, increased utilization ratio to wind, have overflow hole on the blade, can increase and utilize the power-assisted of wind next blade, reduce the blade resistance, increased the second use process of utilizing wind, thereby improved the efficient of this wind-driven generator greatly.
Description of drawings
Fig. 1 is the wind-driven generator three blade structure schematic representation in magnetic suspension Savonius rotor carry potential overflow of the present invention hole;
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, overflow hole 2, blade 3, base disk 4.
Embodiment
Shown in Fig. 1～2, magnetic suspension Savonius rotor blade of wind-driven generator overflow hole comprises rotating shaft 1, overflow hole 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 in rotating shaft 1 along circumference, and the side of blade 3 is fixed in the rotating shaft 1, and the bottom is fixed on the base disk 4, and each blade 3 root all is provided with several overflow holes 2 vertically near the position of axle.
Shown in Fig. 1～2, blade 3 can be for one or more, and blade 3 is not traditional semicircle, but be curvature from the axle center outside ever-reduced curvilinerar figure.
Shown in Fig. 1～2, have an overflow hole 2 on each blade 3 at least, the shape of overflow hole 2 can be the rectangular that has fillet, also can be other shapes.
