Description
Technical field
It is specifically a kind of for being segmented the composite material of wind-powered blade mold the present invention relates to wind turbine leaf blade mould field
The connection method of shell.
Background technique
Wind energy is as a kind of clean renewable energy, the increasingly attention by countries in the world.Its amount of accumulateing is huge, the whole world
Wind energy be about 2.74 × 109MW, wherein available wind energy be 2 × 107MW, than the water energy total amount that can be developed and used on the earth
Also want 10 times big.Wind is utilized by people very early, is mainly drawn water by windmill, flour milling etc., and present, and people are interested
It is how to use wind to generate electricity, the principle of wind-power electricity generation is to drive air vane to rotate using wind-force, then will revolve by booster engine
The speed turned is promoted, to promote electrical power generators.According to the technology of current wind-power electricity generation, three meters of gentle breeze about per second
Speed can start to generate electricity.Wind-power electricity generation just forms one upsurge in the world, because wind-power electricity generation does not have fuel problem,
Radiation or air pollution will not be generated.
As country greatly develops clean energy resource, wind-powered electricity generation industry also rapidly develops therewith, the MW class of wind electricity blade
Not increasing, the length of wind electricity blade is from original more than 40 meters till now more than 80 meters, because the length of wind electricity blade is subsisted
Become to lengthening, the length of mold is also with lengthening；For convenience of the production, transport and installation of mold, mold usually requires that point several
Duan Jinhang production and transport, the segmentation of mold, the segmentation including steel construction and composite material casing are more and more common.Traditional answers
Condensation material housing segments generally use one or more works such as bonding, hand paste, vacuum injection when mold is installed, in segmentation position
