Abstract
The utility model relates to a blade of a vertical axis wind generator, which comprises a blade main body, an opening arranged in the middle of the blade main body, a fixed plate in the middle of the opening and end plates arranged at two ends of the blade main body; the transverse section of the blade main body is in the form of a streamline wing; furthermore, the middle of the blade main body is wide; and two sides of the blade main body are narrow. By adopting symmetrical streamline wings, the blade has steady maximum lift coefficient in a separation region, so that a good power generation effect can be played.
Description
Technical field
The utility model relates to a kind of generator blade, is specifically related to a kind of vane of vertical shaft wind-driven generator.
Background technique
Wind-driven generator is divided into two kinds of horizontal axis and vertical shaftes, and the running shaft of horizontal axis wind-driven generator is parallel to the ground, the blade face rotation of facining the wind.Noise was big when small-sized horizontal axis wind-driven generator rotated, and influenced people and normally had a rest.Large-scale horizontal axis wind-driven generator is made complicated, and the unit price is high, has influenced the electricity price that is incorporated into the power networks.The vertical axis aerogenerator running shaft is perpendicular to the ground, is divided into two kinds of resistance type and lift-types, and resistance type wind-driven generator startability is good, but generating efficiency is low, and lift-type wind turbine power generation efficient is high, but startability is poor.In the interconnection technique of vane of vertical shaft wind-driven generator and wheel hub, there also have just in order to reduce resistance of air to be convenient with location and installation and adopt and have certain fairshaped structure and be connected, and its effect just reduces resistance of air and do not increase moment of rotation.With respect to the conventional horizontal axis wind power generator, numerous advantages such as vertical axis aerogenerator has the design method advanced person, wind energy utilization is high, starting wind velocity is low, noise free have wide market application prospect more.And the blade of general vertical axis aerogenerator is very common fairshaped shape, just relies on the effect of wind-force purely, and has ignored the characteristics of blade itself.
Summary of the invention
Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art, a kind of stable vane of vertical shaft wind-driven generator with maximum lift coefficient to be provided.
Technological scheme: the described vane of vertical shaft wind-driven generator of the utility model, it comprises blade body, is located at the opening at this blade body middle part, the fixed plate in the middle of this opening, and the end plate that is located at said blade body two; The lateral cross section shape of said blade body is the streamline aerofoil profile, and middle wide both sides are narrow.
The lateral cross section shape of the shape of said end plate and said blade body is the same.
Said blade body is fixedly connected with connecting rod through the opening of center.
Said connecting rod is distributed on the main shaft.
The part that said blade body two is narrower is also inequality, is a narrow limit of circular arc and the narrow limit of triangle.
Said blade body structure adopts symmetrical streamline aerofoil profile, and stable maximum lift coefficient is arranged in the separation zone, has bigger ratio of lift coefficient to drag coefficient, and less Ra influence characteristic is little to the stall influence.
The described vane of vertical shaft wind-driven generator of the utility model is applied in fields such as ship and Motor Vehicle.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: adopt symmetrical streamline aerofoil profile, make blade that stable maximum lift coefficient arranged in the separation zone, play good generating effect.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Of Fig. 1, Fig. 2 and Fig. 3, the described vane of vertical shaft wind-driven generator of the utility model, it comprises blade body 1, is located at the opening 2 at this blade body 1 middle part, the fixed plate 3 in the middle of this opening 2, and the end plate 4 that is located at said blade body 1 two; The lateral cross section shape of said blade body 1 is the streamline aerofoil profile, and middle wide both sides are narrow; The lateral cross section shape of the shape of said end plate 4 and said blade body 1 is the same; Said blade body 1 is fixedly connected with connecting rod 5 through the opening 2 of center; Said connecting rod 5 is distributed on the main shaft 6; The part that said blade body 1 two is narrower is also inequality, is a narrow limit of circular arc and the narrow limit of triangle.The utility model adopts symmetrical streamline aerofoil profile, makes blade that stable maximum lift coefficient arranged in the separation zone, plays good generating effect.
The utility model does not relate to all identical with the existing technology existing technology that maybe can adopt of part to be realized.
