The low wind speed region wind-power electricity generation of China has been stepped into the large-scale development stage, but how to improve low wind speed regional generation Efficiency, is always a problem.The strategy generally taken in the market is lengthened blades, increase rotor diameter and uses increase The mode of tower height, these methods can obtain higher wind energy to a certain extent, improve the generating energy of wind power generating set Power.But lengthened blades, increase tower height will certainly increase the weight of wind power generating set, and some part dimensions and weight also can Increase therewith, a series of problems, such as thus also resulting in cost increase, transport difficult, influence unit safety.
The blade of wind power generating set is the critical component that wind power equipment converts wind energy into mechanical energy, and its manufacturing cost is about Account for the 15% to 30% of wind power generating set totle drilling cost.Blade is typically based on Design of Aerodynamic Configuration and shows peculiar aerofoil profile, should The lift-drag ratio of the blade of aerofoil profile is more big more can improve blower fan catch wind efficiency, and then improves the power output of blower fan.But blade is just In normal operation process, the resistance that blade tip and blade root are subject to is larger, reduces the utilization ratio of wind energy.
Utility model content
The purpose of this utility model is to provide a kind of synergy spoiler blade, and it is intended at least partly solve existing low wind Speed generator group, the technical problem that resistance is larger, wind energy utilization efficiency is low that blade is subject to.
The technical scheme that the utility model is provided:A kind of synergy spoiler blade includes blade body and synergy spoiler; The blade body has tip, butt, leading edge, trailing edge, blade pressure surface and blade suction surface;The synergy spoiler is arranged Near the butt;
The synergy spoiler is arranged on the blade body close to the side of the butt, one or more synergy Spoiler is from the trailing edge direction of the blade body, and compartment of terrain is set in the blade pressure surface and the blade suction surface On.
Further, the curved hardened structure of the synergy spoiler, its surface is convex to the tip.
Further, the synergy spoiler is in Y-shaped shape, its described trailing edge of top away from the blade body.
The beneficial effect of synergy spoiler blade that the utility model is provided is:
First, one or more synergy spoilers are set near the butt of blade body, from the trailing edge side of blade body To compartment of terrain is set on blade pressure surface and blade suction surface.This set can increase absorption of the air-flow in blade surface Ability, at the same can block from blade open up to air-flow, make exhibition to air-flow change direction and be converted into promote blade rotation Lift, and during synergy spoiler rotates with blade, formation that can be to be vortexed at the trailing edge of interference blade increases blade Lift, reduce the resistance of blade, improve blade to the utilization ratio of wind energy.
