Abstract
A small size vertical shaft wind wheel of a wind driven generator comprises a main shaft, vanes, a top disk and a bottom disk, wherein the main shaft is in a vertical state and used for connecting the top disk and the bottom disk and plays a supporting role. The top ends and the bottom ends of the vanes are respectively connected with the top disk and the bottom disk. When wind force drives the vanes to rotate around the main shaft, the top disk and the bottom disk are driven by the vanes to rotate at the same time and at the same speed, and the bottom disk is connected with a rotor part of the wind driven generator and drives the rotor part of the wind driven generator to rotate. In the whole process, wind energy is converted into mechanical energy of the vanes, then the mechanical energy is converted into electric energy through the wind driven generator, and alternating current is output. The vanes adopt wing shape of an aircraft wing and are in a three vane force lifting mode, are evenly distributed on disks, and included angles between each two vanes are 120 degrees. Chords of the vanes are rotated to appropriate angles to increase power wind area and reduce resisting force.
Description
Affiliated technical field
The utility model relates to a kind of small-sized vertical axis aerogenerator wind wheel, specifically is a kind of three blade wind wheels of vertical shaft.
Background technique
The wind wheel form of small-sized wind power generator is varied, but can be summarized as two classes to its classification, horizontal axis wind-driven generator wind wheel and vertical axis aerogenerator wind wheel.Wherein adopt the vertical axis aerogenerator wind wheel with respect to the wind turbines rotor of horizontal axis, to have following advantage: safe, need not tuning, start that wind speed is low, noise is low, wind loading rating is strong, wind energy utilization is high.What the vertical axis aerogenerator wind wheel was commonly used has three types: Sa Woniusi type (S type), Dari eritrea type (Φ type) and rotor type (H type).
Sa Woniusi type wind wheel is combined by two semi-cylindrical shaped blades, about two blades be on two different circumferencial directions, but have certain overlapping.When wind during to wind wheel, the spill blade makes windmill overcome resistance and rotates under the impetus of wind-force, and has higher rotational speed.Advantages such as this blower fan is to utilize " resistance " that wind is generated to come work, and his tip speed ratio is close to 1, and rotating speed is low, noise is little, torque is big.
The Dari eritrea type wind wheel belongs to " lift-type ", is characterized in that the windmill rotating speed can design very greatly.This blower fan is under halted state, and is very little from the torque that wind-force obtains, and is difficult to entry into service voluntarily, and this is the deficiency of this blower fan, for this reason, can constitute combined blower fan with Sa Woniusi type blower fan, in order to improve its startability.
The blade of rotor type wind wheel has the cross section identical shaped with aircraft wing.Advantages such as the detent torque of rotor type blower fan is very little, and this wind wheel has the tip speed ratio height, and running torque is big.But risk is bigger, because the rotational speed height.
Summary of the invention
In order to overcome existing rotor type (H type) shortcoming that the wind turbines rotor volume is too big, difficult shortcoming, Sa Woniusi type (S type) shortcoming that conversion efficiency is lower of Dari eritrea type (Φ type) startup, the utility model provides a kind of novel vertical axis aerogenerator wind wheel, this vertical axis aerogenerator wind wheel structure is rationally simple, volume is little, in light weight, production technology is easily grasped, and can realize breeze start-up.
The technological scheme that its technical problem that solves the utility model adopts is: comprise main shaft, blade, tip circle dish and end disk, it is characterized in that main shaft in vertical state, and be combined with tip circle dish and end disk, blade tip is fixed on the tip circle dish, the bottom is fixed on the end disk, blade is three blade shapes, evenly arranges, and angle is 120 ° each other.The single-piece blade adopts the shape of blower fan wing, comprises inner arc, outer arc and top circular arc, and the top circular arc is that angle is 100 ° circular arc.The size of blade chord length and top radius of arc is different and different according to design power.The axial angle of the string of blade and tip circle dish is 144 °, so that two flabellums of acting utilize wind energy to a greater extent, and the blade resistance minimum of not doing work.Being connected between main shaft and tip circle dish and the end disk adopts flange to connect, and be not only for convenience detach but also can firmly connect.End disk reserves bolt hole simultaneously and partly is connected with generator amature.When wind drove the blade rotation, blade drove tip circle dish and the rotation of end disk, and end disk drives the rotor portion rotation of generator, was electric energy with wind energy transformation in this process.Being connected between blade and tip circle dish and the end disk adopts the M6x50 bolt to connect, and every blade adopts 4 bolts to connect.Blade, tip circle dish and three parts of end disk adopt aluminum alloy material, and it is the material of Q235 steel that main shaft and institute's adpting flange adopt model.
The beneficial effects of the utility model are, combine the advantage of rotor type wind wheel and Sa Woniusi type wind wheel, have both improved energy transformation efficiency of generator, have possessed the performance that low wind speed starts simultaneously, and the volume that takes up room is less, and is safe.
