Description
Technical field
The utility model relates to a kind of blade, specifically, relates to a kind of blade of wind-driven generator of easy access.
Background technology
Wind energy, as a kind of clean regenerative resource, is more and more subject to the attention of countries in the world. Its amount of accumulateing is huge, the whole worldWind energy is about 2.74 × 10^9MW, and wherein available wind energy is 2 × 10^7MW, can be total than the water that can develop on the earthAmount is also wanted large 10 times.
Wind-power electricity generation is that the kinetic energy of keeping watch transfers electric energy to. Wind-driven generator is that wind energy is converted to mechanical power, mechanical power rotor drivenRotation, the power equipment of final output AC electricity. In a broad sense, wind energy is also solar energy, so also can say wind-power electricity generationMachine, is a kind of taking the sun as thermal source, the heat energy utilization generator taking atmosphere as working media.
Blade on wind power plant, owing to operating in for a long time in the comparatively severe situation of operating mode, need to often overhaul at present,But existing blade construction often cannot be overhauled up hill and dale, or the maintenance comparatively effort of getting up.
