Abstract
The utility model relates to a blade angle adjusting washer of a wind power generator, comprising three sections of circular arcs with equal length which are movably arranged; the thickness of each section of circular arc is changed uniformly; and a plurality of installation holes are uniformly arranged on the circular arcs. The washer has a simple structure, is convenient to use and can adjust the installation angle of a blade, so that wind energy can be better utilized.
Description
Technical field:
The utility model belongs to the accessory on the wind-driven generator, and particularly a kind of blade of wind-driven generator is adjusted the angle pad.
Background technique:
The working principle of wind-driven generator is that wind-force blows on the blade back to the four sides diffusion, and wind-force produces air pressure to blade surface, and pressure produces moment of torsion to the generator central shaft, and then drives the central shaft rotation and realize generating.When these blades are installed, must make blade according to unified sense of rotation, with wind wheel self axle serves as that axle turns over a given angle, even the wing chord of each blade and wind wheel plane of rotation form an established angle, the size of this established angle angle has determined startup difficulty, maximum (top) speed and the wind energy utilization of wind.
Summary of the invention:
The purpose of this utility model just is to provide a kind of blade of wind-driven generator to adjust the angle pad, and this gasket construction is simple, easy to use, setting angle that can adjusting vane, so that utilize wind energy better.
As above design, the technical solution of the utility model is: a kind of blade of wind-driven generator is adjusted the angle pad, it is characterized in that: be made up of three sections movable installations of isometric circular arc; The thickness even variation of every section circular arc, and on circular arc, evenly have several mounting holes.
The center of circle angle of above-mentioned every section circular arc is 117.7 °.
Gapped between the surface of contact between above-mentioned every adjacent two sections circular arcs.
Above-mentioned every section circular arc external surface scribbles anticorrosive coat.
The utlity model has following advantage and good effect:
1, this pad is made up of movable installation of three sections thickness even variation, isometric circular arcs, is convenient to processing, transportation and installation.
2, owing on annulus, evenly have several fixedly circular holes, therefore be convenient to of the installation of 3 stops annulus, thereby reach the purpose of adjusting vane plane included angle at diverse location.
3, owing to scribble anticorrosive coat at the outer surface of every section circular arc, so this pad both reached the desired antiseptic effect of harsh weather, helped reducing the caused system vibration noise of variable height again.
Description of drawings:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the side view of every section circular arc.
Embodiment:
As shown in the figure: a kind of blade of wind-driven generator is adjusted the angle pad, is made up of three sections isometric circular arcs, 1,2,3 movable installations.The thickness even variation of every section circular arc evenly has several mounting holes 4 on circular arc, and every section circular arc external surface scribbles anticorrosive coat 5.The center of circle angle of above-mentioned every section circular arc is 117.7 °, and is gapped between the surface of contact between every adjacent two sections circular arcs.
It is host material that this pad adopts manganese steel, and its intensity and toughness all can satisfy the requirement of 1.5-2MW blower fan to material.
