Abstract
The utility model relates to a wind power generation impeller, in particular to a vertical axis machete-type wind power generation impeller, which comprises an upright column, a generator and an impeller; a rotating shaft is vertically arranged; the utility model is characterized in that the impeller has at least 4 hollow blades which are machete-shaped in an overlooking way; the cross-section of the blade is a hollow isosceles triangle; the upwind side of the blade is the bottom of the triangle, while the wind exit side of the blade is the triangular top. The wind power generation impeller is novel in structure and the blades are provided with good wind energy conversion effect; besides, the wind power generation impeller is characterized by small occupied space, strong resistance, high wind energy utilization rate, as well as wide scope of wind power application; and the wind power generation impeller can be widely applied to open grassland, desert and marine for wind power generation, and is also suitable for various vehicles and ships for wind power generation.
Description
Technical field
The utility model relates to a kind of wind power generation impeller, and concrete is a kind of vertical shaft machete formula wind power generation impeller.
Background technique
On our earth, wind resource is contained abundant, and it is wide to distribute, and the amount of wind resource is not second to water resource, and it is renewable to have the energy, and characteristics such as pollution-free are with a wide range of applications.How economic, a large amount of Application and Development wind resources are current important topics.Common wind-driven generator all is to be provided with generator on column, is provided with impeller in the rotating shaft of generator.The impeller of wind-driven generator has horizontal shaft type and perpendicular axis type.The impeller vertical rotation of horizontal shaft type wind-driven generator, for reasons of safety, the mounting point that needs is higher, and it is big to take up room, and wind loading rating is poor, and wind energy utilization is low, and the wind-force narrow application range need be considered the influence of windward side during installation.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of technological scheme of vertical shaft machete formula wind power generation impeller being provided.This technological scheme has and takes up room for a short time, and anti-resistance ability is strong, wind energy utilization height, characteristics such as wind-force Applicable scope is wide.
Structure of the present utility model is: vertical shaft machete formula wind power generation impeller, comprise column, generator and impeller, rotating shaft vertically is provided with, and it is characterized in that, at least 4 in the blade of impeller, blade hollow is overlooked and is big knife-edge, and its cross section is the isosceles triangle of hollow, the windward side of blade is the leg-of-mutton end, and the outlet air surface of blade is leg-of-mutton top.
Establish the oblique rollering steel rope on the described blade.The width H of described blade the widest position is H:F=1:0.3-0.8 with the ratio of place, the windward side of blade thickness F.
Rotating shaft of the present utility model is vertical setting, and impeller horizontally rotates on the column top, can be suitable for the wind comes from of a plurality of directions, the mounting point of impeller needs can be lower like this, because impeller is to be horizontally disposed with, the setting that can just interlace of each wind-driven generator can take less space.Monolithic impeller of the present utility model is overlooked and is big knife-edge, and its cross section is an isosceles triangle, and the windward side of blade is the leg-of-mutton end, and the outlet air surface of blade is leg-of-mutton top, and is very little to the resistance of air, and for alleviating the weight of blade, blade is to be designed to hollow.When blade is big, can between column top and blade, establish oblique rope, to improve its Security.The utility model novel structure, blade have good wind energy transformation effect, have take up room little, anti-resistance ability is strong, wind energy utilization height, characteristics such as wind-force Applicable scope is wide, can be widely used in open grassland, region, desert and seashore wind-power electricity generation, also be applicable to wind-power electricity generation on the various car and boat.
